The Body Builder

by Greggrth

 Steve’s life is about to take a very strange turn when a supervillain called the Body Builder breaks into his lab and causes an accident. Will this be the origin story of a new hero’s rise to glory, or will it spell disaster for the heroes of the city when Super Dick causes all sorts of changes when he can’t control his not so little buddy…

“Morning Tom,” I said as I approached the security desk, tucking my travel cup into the crook of my arm to retrieve my ID badge. I held it over the scanner until the light went green.

“Morning Steve,” the balding guard said, rising from his chair and hoisting his trousers up as he did. “Step on the blue dot please sir.”

I did as instructed, straightening my posture and standing still as Tom went over to one of his screens and started typing on the keyboard. The scanner began to warm up, and over the low hum I could hear the news report from the small TV Tom had been watching.

“—raiding the warehouse with little success for the Wardens yesterday afternoon. Witnesses reported to have seen the likes of Icarus and Watcher in the skies moments before Density and the Expando infiltrated the building. Police were quick on the scene thereafter suggesting a joint effort, but as they were cordoning off the area, Icarus and Watcher flew down to meet a disgruntled Density. It seems that the Body Builder is still at large.”

I tried to surpass a snort at the reporter’s terrible pun. It was such an odd name for the scrawny nutjob running around robbing banks and the like by causing random people to grow into muscle men he would control like his own personal army. The bright side was that both the transformation and the mind control were short lived. From the reports I’d heard earlier, the mind control only worked when the subject was under the influence of the Body Builder’s formula, which he would administer with a dart gun. His target would swell up with muscle and mass and then, somehow, they would do as he commanded, be it ripping safe doors off their hinges, knocking down walls or even throwing cars at the Wardens to cover his escape. Fortunately everyone he’d shot had shrunk back to normal afterwards, unharmed if a little shaken and in the need of new clothes.

“All finished,” said Tom, returning to his chair. “Have a good day sir.”

“You too,” I said, toasting him with my coffee.

My steps were almost silent as I walked across the polished marble floors into the labyrinth of Pymm Technics, the lights coming on one by one to illuminate my way. I had become used to walking into an all but deserted facility ever since I’d been assigned to work with Dr Garner who insisted on working these ridiculous hours. He was the earliest of birds and could only work so early in the morning it could be mistaken for the previous night. Because he was the project lead it was my sleep schedule that had to be fucked up, one that would take me months to get back to normal.

ID badge still in hand I swiped it through the card reader and punched in the code to the lab door and waited for the heavy click before opening it.

“I need those samples,” was the gruff greeting I received before I’d got more than one foot in the lab.

“Coming right up” I said, far too use to this behaviour to take it personal.

I set my coffee down at my desk and slipped my coat onto the chair back. I then donned my gloves and got to work. I could hear Dr Garner moving around on the other side of the lab, able to visualise him scurrying from his standing desk to the sequencer on the opposite side. He would remove his glasses to chew on the arms while he read his notes and then put them back on again to read from the screen. Our deadline was fast approaching and we needed some good results or risk losing funding.

Once I had the samples ready, I brought them over to him. He took them without comment which I took as a compliment.

“They’re are progressing well,” he said after he’d inspected them all. “I’m seeing 13% increase in all samples.”

“That’s good isn’t it?”

“Only 2% better than last time,” Garner grunted. “Not enough with our review coming up.”

Before I could offer any words of encouragement, the sound of the lab lock slamming open drew our attention. We both looked over to see Tom the security guard opening the door for a man in a suit. All I noticed of the man was the vibrant green of his suit, my attention snagged on Tom.

Now Tom may have once had a body of peek physique but time had softened his middle almost as much as it had thinned his hair. I was used to seeing the button of his shirt straining over his belly, now however they seemed to be pulled taunt over his chest. His expression was glazed over, mouth opening and closing while his eyes blinked lazily, unable to focus on anything for long, continuously returning to the man in green.

Standing next to Tom, the man looked short, maybe standing at 5’6” and whip thin compared to the guard’s width. He carried a garish cane with a spherical grip he kept caressing as he looked over his shaded glasses to study the lab.

“Forgive my intrusion,” he drawled, slamming his cane on the ground with a sharp crack. “I’m hoping this is the office of Dr Gordon Garner?”

“Yes?” Garner’s response was hesitant. He was focused solely on the man in green, not seeming to have given Tom a second glance. Maybe it was just me unable to stop staring at the (to me) obvious physical differences our regular night guard had gone through. His black trousers hugged his quads, the cuffs of his sleeves were riding up his wrists and bunched where biceps met forearm. There was also an abundance of biceps there that hadn’t been when I walked past him a few hours ago. “Are you…one of the investors? Our presentation isn’t for a few weeks yet. I’m afraid you’ll have to wait until then. I don’t discuss my work without an NDA—”

The man in green just laughed. “Oh, no I’m not an investor. I am invested in your work but have no intention of paying for it.”

Dr Garner seemed to stall at this. “I’m afraid I don’t understand.”

“My apologies, I thought it was quite clear. I’m here to steal your research.”

Shock dropped Garner’s jaw for a beat but he rallied round quick and his cheeks began to flush with rage. “How dare you?! You,” he gestured at Tom, never having learned his name, “do your job! Remove him from my lab at once!”

During the exchange I hadn’t seen any change in Tom’s expression. He would simply stare at the floor, eyes lifting momentarily when the green man spoke but when it was clear he wasn’t the target audience his gaze lowered again. Every now and then he’d fidget though, one hand rising to adjust his crotch or fumble at his tight sleeves, as though trying to resolve some discomfort. He was pawing at his crotch when Garner yelled at him. The words didn’t seem to reach him. When his hand came away, I was almost certain I could see an above average erection travelling down his right leg, throbbing clearly against the material.

“And here I was hoping this wouldn’t get violent,” the man in green sighed. He opened his blazer and withdrew a gun coloured a hideous vibrant neon green and brandished it at Garner and I. “I don’t have time to dally about now. Give me your research or I shoot your assistant and make him make you.”

“Oh shit,” I breathed, finally realising who was robbing us.

The man in green’s eyes lit up over the rim of his glasses, smile broadening at my recognition. “Your assistant seems quicker on the uptake doctor. Perhaps you’d like to enlighten him as to who I am?”

“Guard!” Garner bellowed. “I order you to apprehend this madman!” He then spun on me. “Is this some kind of joke? Who is he, and why does he say you know him?”

“Well… if I’m not mistaken… this is the Body Builder.”

Garner snorted derisively. “Oh please! You have more muscle than him.”

“Rude,” said the Body Builder. “I grant you, maybe I should have chosen a better name for myself, but I find it fits so well with what I do. Perhaps I need to demonstrate.” Slowly he turned the gun on to Tom, aiming for his thigh. Tom’s clouded eyes followed the gun until it stopped moving and then lost interest again. “I only gave him a mild dose to keep his services for longer, but if this will step things up…”

There was a hiss of air as the Body Builder pulled the trigger. Tom gave a low grunt, head dropping to stare at the dart sticking out of his thigh. Curiosity got the better of me and I found myself staring in anticipation rather than running away.

Tom’s thigh began to inflate and ripple under his trousers. It shuddered and swelled, the dart getting dislodged to clatter on the floor. The growth spread outwards, Tom’s trousers getting tighter and tighter, the heads of muscle swelling out and becoming clearer. I could see his dick throb and thicken as well, earning a grunt of discomfort and possibly pleasure from the growing guard. The cuffs of his trousers began to rise and I could see his shoes begin to swell and creak as his feet grew too. His belly began to recede, the mass seeming to move upwards and spread across his chest. He moaned again, straightening up as he appeared to get taller, spreading his arms out as lats stretched out. His pecs ballooned against his dark blue shirt, pulling at the buttons to give a glimpse of his hairy chest. The collar was the first to go as his neck thickened with a deepening growl coming from it. Traps rose up and delts stretched out his frame even more.

Tom’s glazed expression had quickly evolved into one of rapture and awe; his eyes drank in his growing form, watching himself bring an arm up and flex until the sleeve burst off, his chest sending two more buttons flying as they broke free. His shoes came apart with a pop, inseams of his trousers splitting open. The tails of his shirt fluttered around his narrow, chiselled waist, several inches from the waist band which while too wide for his core was struggling over the swell of his quads, glutes and crotch. And speaking of crotch… a wet patch was spreading out from the flaring, clearly defined mushroom head pushing against his trousers, moments before the monster sprang free in a flurry of tattered trousers and spatters of cum. Tom gave a below of relief, feeling his pecs, tugging the strips of shirt off of his arms as they cut into him.

I had to admit I was rock hard myself. I’d always like muscular men and to see Tom swell up to this Titan was pushing buttons I hadn’t known I had. He’d only grown to about 6’11” but his frame was immense. I struggled to think how much muscle he’d packed on, his heaving shoulders easily wider than the door behind him. He looked all the more massive standing next to the diminutive form of the Body Builder, who had pulled out a tissue to wipe off a few splatters of cum from his shoulder.

“Should have known he’d be a gusher” he muttered to himself. “Now, I’m on an ever tighter schedule because of that demonstration so give me your research now or my henchman will break your assistant like a toy. No offence,” he added, giving me a sparing glance. The Body Builder’s posture suddenly stiffened. “Shit.”

With surprising agility, he leapt forward just as a dark figure flew through the wall behind him like a ghost, landing on the spot the man in green had stood moments before. Tom reacted with an immediate swing of his powerful arm, striking the figure and knocking him clear across the room into the empty fridge hard enough to shatter the glass in the door. My scrambling brain tried to discern how this figure had managed to pass through a wall like it wasn’t even there but then take a hit from the pumped up Tom, dent a reinforced fridge and still stand on his own feet. Then I took in the outfit and realisation struck.

“Density,” I breathed.

The real life superhero was in our lab, rolling his bulky shoulder as shards of glass fell off him. His suit was skin tight, showing off every bump, curve and crease of his muscular form. The majority of his suit was a shiny black, with swaths of dark purple running over his chest and shoulders, bands running over the crooks of his elbows and patches on his quads. He also wore a pair or speedos of the same colour. He brought his gloved hand to massage his smooth, chiseled jaw, his black mask over his eyes somehow whiting them out so it was impossible to tell where he was looking. His skin was a dark caramel, hair darker than his suit and swept back to show off his sturdy, furrowed brow.

Despite the situation, I couldn’t help but find myself thinking, not only was he hotter in person, but bigger as well. The stomp of his boots. The way his quads rippled as he shifted his weight was clear to see beneath his suit, he may as well have been naked. Suffice to say, I had the hots for the hero, as the collection of pictures taking up a folder in my phone I would often peruse while waiting on test results in the lab, pulled into my desk to hide my hard-on. Now to have him here, in the flesh, it was almost a dream come true…if not for the danger.

The Body Builder lifted his gun and fired a quick shot, but Density tensed his pecs and the dart bounced off. His power was the ability to alter his mass and density at will; able to become solid enough to stop a car or to become insubstantial enough to pass through solid objects. The hero gave a few extra cocky bounces of his thick chest as a taunt but the villain didn’t fire again. Instead he snapped his fingers.

“Deal with him,” he ordered.

Tom pounced like a jumbo tiger, his first blow meeting Density’s raised hand with the sound of 2 boulders clashing rather than flesh. I was distracted from the fight when the Body Builder spun round in a graceful arc and struck Dr Garner with his staff against his jaw. The doctor fell against me, causing me to lose my balance. I had enough sense to catch him and slowed our decent to the ground, except Garner caught his head on the edge of the counter with a sickening crack. The Body Builder bore down on us, ignoring Density and the ‘roided up henchmen he’d made of Tom.

“Research, now” he demanded simply. When Garner didn’t respond, he jabbed him in the chest with his staff. “I didn’t hit you that hard, stop faking.” After waiting a beat and the doctor still didn’t stir, he sighed in frustration and then turned on me. “Did he have a fucking glass jaw or something? What a wimp.”

Meanwhile one of the blows Density landed against Tom’s chest was so powerful it made the widows rattle. But all the security guard did was grunt and stagger back before following it with a blow of his own. The blow never landed, in fact his whole arm passed harmlessly through Density’s grinning face. The giant staggered forward, unbalanced while the hero stepped out of his back and then swung a well shaped leg to boot his butt and send him head first into the fridge.

The tip of that bloody cane tapped my chin and forced my attention back onto the Body Builder. “Ignore them and focus on yourself. Where does he keep his research files?”

I pointed to his standing desk just as Tom ripped the fridge from the wall and hurled it at Density. The hero crossed his arms in from of him and then flung them apart, the fridge frame bending and buckling even more as he deflected it to cash into the desk and smash the desk, and the computer into pieces. The tray of samples I’d compiled were launched across the room and spilled their contents over the floor in the corner.

“Of course,” the Body Builder sighed as the titans clashed behind him again. “Well, plan B, you’re going to cart the doc out of here so when he wakes up, he can tell me what he knows.”

“No!” I cried, feeling like a deer in the headlights as the villain lifted his gun and aimed it at me. His angular face twisted in a sneer as he pulled the trigger.

Just as he fired, Density hurled a beaker past Tom’s bulk and struck the Body Builder on his shoulder. I heard the gun go off, flinched and frantically searched myself for the dart but felt nothing. It must have missed.

Meanwhile, when Tom twisted to inspect what had caused his master’s distress, Density closed one hand over the other, lifted them both overhead and brought them down swiftly into the back of Tom’s head. The swollen security guard’s eyes lost focus and he tottered to one side. Density quickly followed him with a kick to one of his knees and when Tom toppled forward, Density’s fist was already swinging up to meet it. The force of the blow shook the windows again as Tom was lifted off his feet a few inches and fell back, sprawling across my desk for a beat before it buckled and broke under his weight.

“Fuck,” grumbled the Body Builder, more disgruntled than angry. He eyed me and then Garner’s unconscious form and then finally Tom sprawled out on the lab floor. “Fuck.”

Density, slightly winded from his battle made his slow way to the villain, heavy booted feet crunching glass and plastic debris that littered the floor. “Back up is on the way,” he panted, chest heaving beneath his suit. “Surrender peacefully or—”

“No thanks” snorted the Body Builder and lifted the gun again as he lunged for me. He grabbed me by the shoulder and hauled me up with surprising strength. Dr Garner rolled off my lap, face hitting the floor. Density was already charging towards us, hands outstretched to grab the gun. It went off, I saw it bounce off of his chest again, saw it ricocheted back towards the Body Builder, skim past his arm just before I felt it pierce my neck.

I felt a flush of heat spread from my throat, then the world spun as Density crashed into me, wrenching me from the Body Builder’s grasp and sending us stumbling into the corner of the lab. I felt the bite of glass against my back while the front was getting smothered by the lycra costumed expanse of a superhero’s pecs. Well, if I was going to die at least I would be happy.

Density’s strong arms cradled me as he set me in the recovery position and then hurried after the fleeing figure of the Body Builder. I remembered seeing his purple clad backside swaying before me as he ran, dreamily wishing I could have a piece of that cake.

I’m not sure how much time passed, while I laid there on the floor, still feeling a pulsing heat in my throat coupled with a spreading chill running through my hands like icy pins and needles. I was vaguely aware I was in a puddle of something but couldn’t find the will to move.

“He’s gone,” I heard Density saying, “took off through the window and had one of his hover scooter things waiting.” There was a pause and then he continued aggressively, “Well Icarus had better get his feathered backside moving then! I held him for as long as I could, it shouldn’t have taken them this long to get here.” Another pause. “Just the one. He’s knocked out so should shrink back down soon. I’ve two injured civilians as well in need of medical attention.”

My vision went dark. For a moment I thought I was passing out, until I noticed the purple speedos containing a hefty basket. Density had come to check on me, squatting down with his legs spread. I quickly pulled my gaze away and pushed myself up off the floor.

“Easy there sir,” he said, a supportive hand coming up to help me rise gently. “It’s all right, he’s gone now and medical help is on the way. Can you tell me your name?”

“It’s Steve, and thank you” I said, grateful my words weren’t slurred despite how foggy my head felt. I reached up to rub my neck and brushed the dart out. It fell to the floor with an accusing clatter and I heard Density inhale sharply.

“You got hit” he stated. His white eyes gave nothing away but I think there was a pucker of concern on his lips. He had nice lips, full and just begging for a kiss. This close I could see the fine shadow of stubble starting to grow through.

“Yeah, I saw it bounce off of you and hit me,” I said, touching the hot patch of skin the dart had pierced. The silence that rang from the hero made me rethink my choice of words. “It was an accident, I know, you were trying to save me, I don’t blame y—”

“Why haven’t you grown?” he asked, cutting me off. “His formula is normally nigh instantaneous. How do you feel?”

“Like that Katy Perry song. I’m hot then I’m cold…” I trailed off as I took in more of the hero’s frame. His suit hugged him incredibly well, it was honestly like it was painted on, how tightly it clung to him and showed off every striation of muscle. The speedo was the only part that had enough extra room to leave some mystery. I could see it sag with the weight of the package but there was no visible penis line. “Feeling very hot now.”

I shifted off my hip to sit on my backside, spreading my legs and resting against the wall. I was now shamelessly staring at Density’s body, groping my crotch as I started to get hard. I wanted so bad to reach out and get a handful of those purple pecs, to see what the material felt like, and just how firm his muscles were. I lifted my gaze up that thick neck, seeing the hero bite his lower lip, brow furrowing slightly. There was a twitch from my groin as it pushed against my hand. Suddenly my trousers and underwear were feeling tight.

“What’s…what’s happening?” I asked, a small part of me rising above the horny cloud that had enveloped me. “Why does my dick feel…”

Density and I both looked down. My crotch was twitching and swelling, it had ballooned into an orange sized bulge, considerably bigger than it should have been, and with a start I watched it jump and swell bigger. I could see my balls growing larger, lifting up a thickening, plumping dick to push against the fabric of my trousers. I could feel my cock sliding across my thigh, feeling I was just chubbing up into an erection but it had already surpassed what used to be my full size.

“It’s… it’s just your dick growing,” breathed Density. “I’ve never known his formula to do that.”

“Why is it getting so big?” I asked, trying to stay calm as my package continued to swell, the confines of my clothes becoming restricting, moving from uncomfortable towards painful. “Seriously, how big is it going to get?!”

“I don’t know. How… how big is it normally?”

“Not this big!” I snapped, grunting as the salami and plums continued to grow and grow. My shaft was a clear tube across my lap, reaching over to my left hip while my nuts were pushing against my thighs forcing me to spread them wider.

“We’d better let it out,” said Density, his large hand going for my crotch.

“W-wait!” I sputtered, but when his palm brushed my shudderingly shaft it turned into an embarrassing moan. Just that slight tough sent tingles of pleasure running along the large surface area of my cock. My eyes rolled and toes curled, I thought I was going to cum. I felt a spurt of warm liquid ooze out as Density popped my fly open and tugged on my trousers. I’d picked a pair of bright red boxer briefs, the only splash of colour in my usual black and grey underwear drawer, my cheeks going a similar colour now that such a hottie like Density was seeing them. I lifted my hips to help get my trousers down until we were both staring at my comically straining red boxers trying to contain my growing cock.

There was a hesitancy in the way Density held his hand over my groin, hovering there for a beat before he pulled on the waistband. As though sensing a way out, my cock made a break for freedom, the head shiny with pre, leaving a trail as it slid up to my navel but continued to stretch higher up my stomach. My jaw dropped and I spread my legs, feeling my nuts flop down with a bouncy jiggle. My dick throbbed, still steadily getting bigger, thickening into a coke can cock but promising to get even bigger.

I vaguely heard Tom moan, caught a glimpse in my periphery of him starting to shrink down, but Density only had eyes for the monster of a dick attached to my groin. The hero changed his position, knees going to the floor and resting on his haunches.

“I… I…” he stammered. “Fuck, that is a big dick.”

In response my dick throbbed and swelled a little bit more. Hesitancy tightening his burly shoulders, the hero reached out for my shaft again. He brushed it with his fingers, causing my stomach to flip and making me bite my lip to keep from crying out again. The head flared and oozed a heavy stream of pre onto my shirt, but I didn’t care. Density licked his lips. His hand rested against my shaft, fingers trying to encircle it but finding he couldn’t get his grip all the way around.

“So thick,” he breathed, and then gave a wheeze of a laugh, grinning, “I can feel it pushing against my fingers. It’s still getting bigger.”

I saw his Adam’s Apple bob as he swallowed, again his tongue slipping out to wet his lips. I began to wonder what it would feel like to have those luscious lips wrap around the head of my massive dick. What would it feel like to have his tongue roll over the glands. Density started to lean forward.

“Density!” a sharp voice cracked the moment like a rock through a window. It echoed down the corridor and into the lab and snapped us both out of our stupor. “Where’s the injured civilians?!”

“In here” Density called back, his voice hoarse. He quickly rose to his feet, and I saw his purple speedos tenting over his impressive erection. Well, it was impressive to my normal standards before my cock grew well into double digits. He quickly tried to adjust himself to make the tent less obvious, hunching over to bring his hips in while vigorously rubbing his forearm to try and redirect the blood flow. “We’ve got a bit of a situation,” he called again before a man and woman carrying medical gear came into the lab.

I expected the pair of them to stop and gape at me, but I got the briefest of glances before they descended onto Tom first of all. The man withdrew a blanket that looked like it was made of tin foil, draping it over the guard’s lower body while the woman opened Tom’s eyes to check his pupils and then felt the pulse at his neck. The pair worked like a well-oiled machine; he sprayed something onto Tom’s chest while she prepped a needle, jabbing it in as soon as he’d wiped the skin down. They then began collecting samples, in what I’m not entirely sure was legal without Tom’s consent. The guard was in no position to comment though, still away with the fairies while he was swabbed and checked.

“He’s stable, he’ll be fine,” said the woman. “Best to give him an overnight stay at St Margaret’s just in case but looks like it’s left his system already.”

Then the pair turned their attention to Dr Garner. I’ll admit to feeling a little hurt. I mean, granted I was conscious and perhaps the other two did take priority with possible head trauma, but come on! I was sat there with a dick that had grown to maybe almost two feet with my nuts filling my bright red underwear like I was smuggling a paid of grapefruits in them. Surely I should have garnered a bit of attention? That was when I realised that since their entrance and my distraction, my dick had stopped growing. I snuck a glance over at Density and saw his erection had settled but he was doing his best to look anywhere but at me.

“We’re going to need an ambulance for this one,” the woman said, waving her torch over Garner’s eyes. She pressed the radio on her shoulder and then barked off a series of instructions while her partner checked Garner’s air waves and attached a mask over his face. “Did you say this one was the target?” the woman asked, breaking her string of instructions to fire the question at Density.

“Yeah,” the hero grunted, voice still sounding a little strained. “He was after the doctor’s work but wasn’t successful.”

“Probably best to take him to a secure location” she said before relaying the same thing to the person on the other end of the radio. All she got was a crackly “Copy” in response before she rose up and approached me.

I did not like the way she stood over me, staring at my exposed penis. Despite its size I actually felt it almost shrivel up under that cold grey stare. I was beginning to wish they’d focus on Tom and Garner again.

“Hmph,” she grunted. “Haven’t seen his serum do that before. I assume it wasn’t like that before you got shot?”

I shook my head.

“How big was it before?”

My cock was definitely softening now as with a rush of heat I felt like all the blood in my body was marching to my cheeks. “Erm…about…S-ss-six inches.”

“Hmm, so we’re looking at a 250% increase at a guess. I don’t see any unhealthy swelling or threatening growths, it looks to be just a healthy penis. Admittedly a quite impressively large one. Well, have to run some tests, just to make sure everything is all right. Think you can get it back in your trousers or do you want a blanket?”

“Can I have both?”

“Sure,” she said matter-of-factly. “I’ll arrange transport to Eugene Labs and they’ll—”

“No!” Density blurted, then coughed and covered his mouth. “I mean it would probably be best if he came back to base… for protection and… observation.”

“Why?” asked the woman, her voice dropping a few degrees. It didn’t look like she was used to being contradicted.

“Watcher will want to take a look at him, and his lab equipment will be better than what they have at Eugene Labs.”

“But Watcher isn’t technically a medical Doctor.”

“He can do all the fancy scans anyone would ask for in a blink. Besides he’s the one leading the charge to break the Body Builder’s formula, he’d want to get first look at someone that erm… reacted… like this.”

The woman frowned hard at the hero who despite his greater size and stature seemed to shuffle awkwardly like a little boy caught doing something he knew he shouldn’t. Her icy glare thawed however and she sighed. “It’s your call, on your head be it. But if he’s coming to base we need to bag him.”

The trip to the mysterious base was a disorientating one. Once I’d stuffed my soft, yet still quite larger dick into the leg of my trousers and wrapped myself in their foil blanket, I was escorted to a sturdy looking 4x4, bundled into the back where a black sack was draped over my head. I’d never been car sick before, but without a point of reference every slight turn felt like we’re were hitting every roundabout and doing the loop 3 times. I was relieved when we got to a stop, felt Density’s strong hands help me down from the 4x4, it was however short lived when he stopped me from removing the hood and instead I was put into a different car. I was very aware of Density sitting beside me, the car being much smaller than the 4x4, and the proximity causing my cock to chub up uncomfortably.

There was also the strange sensation in my balls. They felt very sensitive, I could feel the vibrations of the car and it was causing a tingling sensation…which was quite pleasant honestly. I really wanted to touch them, part to try and find a comfortable position and the other just to rub them. They were begging for attention. They felt so full, and tight, like I was a horny teen again that needed to get off just to relieve some of the pressure.

“Are you okay?” Density’s voice was a soft rumble, shoulder bumping mine as I imagine he lowered his head to my ear.

“Yeah,” I said, my voice coming out strained until I cleared my throat. “Everything’s just… tighter than I’m used to.”

“I’ll say.” There was a pause, hanging heavy in the air. “Do…do you need any—”

I flinched when I felt his hand on my lap, started by the sudden contact. Density seemed to pull away from me as much as the car would allow and didn’t speak again until we arrived.

The bag stayed on as I was hustled and jostled about, gripping my blanket tightly around my waist, waddling awkwardly with my cock down one leg. It was a weird sensation, not comfortable in the slightest, yet the constant rubbing was causing blood to flow into the shaft, making it hard, and therefore harder to walk. Mercifully before long they ushered me into a room and the hood was removed.

I blinked against the sudden light, blinded by what felt like over an hour of darkness. I had to blink a few times to get my eyes to work, to take in my surroundings. I’d expected a laboratory, but it looked more like accommodations, like someone’s living room. It was very Spartan, with hardly any decoration and lacked the warmth of it actually being lived in. I’d been placed on a sturdy armchair, the arms and back rest all one curved piece making me feel like I was in a cup. I was still clutching my foil blanket, but my nuts were feeling mashed in me trousers and I wanted nothing more than to let them out to breath.

“I thought it best to wait here,” said Density, standing on the opposite side of the room, arms crossed causing his purple pecs to bulge and rub against his tight, toned arms. His thick legs were placed firmly apart, like he was ready to lurch into action at the slightest need. Whether it was to lunge towards me or away was unclear. “Watcher and Icarus are still out and rather than wait in the lab I thought… my room might be more comfortable.”

“You live here?” I asked.

A shrug of his shoulders. “Sometimes. When there’s a crisis on or there’s a threat and I need to be close to the action. I have my own place out in the city, that’s where I spend most of my nights when I’m not fighting crime.”

“Cool,” I said, mentally kicking myself as soon as the words left my mouth. People only say cool when they have nothing to say. “Have they caught up with the Body Builder yet?”

“I’m afraid he gave us the slip,” sighed the hero. “But don’t worry, we’ll find a solution for your… pre-dick-ament. How… how does it feel?”

“Right now it feels uncomfortable.” My balls were feeling as tight and full as ever, warm against my inner thigh. It was almost like I had two warm water balloons sloshing about.

“Did you want to… take your trousers… off?” I clutched the blanket tighter. “Just because, I mean, if it’s uncomfortable for you, having it all packed in like that, you can… let it out.”

While he did have a point, there was a small flicker of dignity I was desperately trying to keep hold of. Take my clothes off in front of this hot specimen in spandex? Normally when I got my meat out it was to a picture of him, I was afraid what would happen if I took it out again with the real thing before me. Would the Pavlovian dog rise up and beg for attention? Unfortunately the feeling of discomfort was steadily chipping away at my resolve.

I stood up, releasing my death grip on the blanket and letting it fall to the floor. I could only guess from the tilt of Density’s head, his white eyes betraying nothing, that his gaze had dropped to my groin. I too took a moment to appreciate the thick bulge of my shaft running down one leg, the swell of my nut sack pushing out and weighing my waistband down. I unbuttoned my trousers, stepping out of my shoes as I did. The sensation of my crotch bouncing off my legs, swaying heavily with my movements was a heady, confident boosting experience. I heard Density clear his throat when the head of my cock, which had slithered out of the leg of my boxers, came into view as my trousers pooled at my feet. I stepped out of them, and thinking I’d gone this far, may as well go all the way.

There was another strange, strangled noise from Density as I took my boxers off. It was as though he was about to tell me to stop and nearly bit through his tongue to stop himself. I was distracted by the relief I felt as I shoved my boxers down and my junk swung free. Fuck, it had been so tight in there! My dick flopped about, there just seemed to be soo much of it. Even rested atop my tight balls the head was nearly down to my knees. Had it been growing steadily this whole time still?

I must have been staring so intently at my dick, I didn’t notice Density approaching until I saw the purple of his speedos come into view beside my swollen flesh. I could see his erection tenting the material again. My own dick twitched, a strange feeling of…I don’t know what, pride, smugness, sexual prowess, flooded through me at the difference in size. He had more muscle in one leg than I did in my whole body, but my soft dick could dwarf his hard one with ease.

I lifted my head, he looked taller up close, and looked into his handsome face, his caramel skin begging to be touched, full lips parted slightly. I could feel his eyes on me, even if I couldn’t see them. I wondered what they looked like, what colour they would be. I wanted to see them. Slowly, I lifted my hand towards his face.

Density’s face came down to mine. He pulled me close and kissed me. He’d misread my attempt to unmask him as a desire to kiss him, and believe me, I was not complaining. I gripped onto his solid, broad shoulders, digging my fingers into the hard heads of muscle as his thick tongue probed my mouth. His strong hands fisted in my shirt, steel like arms encircling me and pressing me into his rock hard, pumped body. My fingers were flying over his traps and back, feeling all that muscle rippling beneath the tight spandex. Fuck he was ripped.

Just as suddenly as he’d started, Density pulled his head back and the kiss broke. My racing heart tripped over itself, lungs gasping for air as I wondered what I’d done wrong. Was I a bad kisser? Had I used too much tongue? Not enough? Density wasn’t looking at me though, his head was down and the hands on my shoulders began to push me back.

“I’m sorry,” I started, until I felt it.

I looked down to see the cause of Density’s change in attitude. My dick had chubbed up, rising to slide between the hero’s powerful thighs and lift his own crotch which rested atop my shaft. I could feel my dick throbbing still, getting thicker and harder and realised it was only a semi. Wordlessly, Density lifted his leg to let my dick out. We both watched as it rose up steadily, past his crotch, up his abs, the head just stopping at the underside of his purple pecs. It poked against them and a large bead of pre oozed out.

“Holy shit,” he breathed.

I was in awe too. Because of the height difference, my cock measured further up my chest. I could probably lean forward and kiss the head if I wanted too. The swollen head looked like it would be a mouthful too.

“That’s so hot,” Density said, voice a low, breathy rumble. He was going to grab it, I could see the need in his face, and fuck, did I need him to touch it too.

A shrill beeping shattered the peace and the moment. I saw something flashing on the hero’s wrist.

“For fuck’s sake!” he all but roared, clamping his mouth shut and swallowing hard before activating what I assumed to be earpiece. “Go” he said sharply, his hand catching my wrist to keep me in place in case I’d thought his ire was directed at. His face fell. “But sir I—…Yes it was my call but—… we followed proce—… I felt it was a necessary ri—.” He gave up trying to speak and instead grunted “Affirmative” at regular intervals. Finally he signed off and then grabbed my face and pulled me into a kiss.

“I’m sorry this keeps happening,” he said in a low whisper. “I swear the universe is actively against me on this. Please know that I’m not trying to jerk you around or anything, I will be back, I just have to get my bollocks handed to me, and then I’ll be back to help with yours. I promise.”

And with that he gave me another kiss, this one more gentle and marched out of the room, his gait somewhat stiff. I watched his pert backside vanish around the corner and heard a door open before silence fell and I was left alone.

My cock throbbed, almost angrily at being denied attention yet again. My balls felt like they were actively punishing me for getting riled up but with no release again. I let out a grunt as they physically shuddered and dropped lower, swelling bigger against my legs. I staggered back, cock swaying in the air and my massive nuts bouncing too until I gripped the back of the armchair for support. I swear I could hear the cum sloshing inside my balls as the grew bigger and bigger. It was like all this horny energy was making them produce it, forcing them to swell to accommodate it all. And fuck they were feeling full.

“Wow, no wonder Power Bottom was so desperate to bring you inside.”

I spun and nearly fell over when the weight of my nuts trailing behind shifted my centre of gravity. My cock waved in front of me and I fumbled to push it down with one hand while the other reached for the silver blanket. I tried to cover my hardon as best I could, but the monster kept pushing itself back up, refusing to go down. I just stood there with a tin foil tent dangling before me.

The intruder giggled at me. He was long and lanky, but with well shaped bulges along those long limbs in all the right places. He was in a super suit, a vibrant blue with gloves and boots a darker shade. It had a plunging neckline to show off a set of shapely, pale pecs, and a belt cinched tightly around his waist. It had a large round buckle with a sideways figure 8 like an infinite symbol. It was warped however, designed to look like a rubber band looping around itself.

With a start I realised this was Expando, another member of the Watcher’s heroic squad. His body was essentially like rubber, and he could stretch and expand himself to near limitless dimensions. He normally had an overhead mask on, but right now his face was bare. I’d only ever seen him with that blue cap on his head, but now I could see his tousled curls, straddling the boundaries of brown and blonde to the point I could quite decide which it was. He had a pointed chin with a little dimple. And he was grinning as fair blue eyes shamelessly roved over me.

“I know,” he said, pulling a mock embarrassed face, “you’ve seen my face without my mask on. Secret identify ruined, on no! But, I think I can trust you to keep this quiet, right?” He lowered his head to look at me through his lashes, bringing a finger to his puckered lips to tap them.

When I didn’t respond he moved his hand to pinch his chin in thought, looking me up and down again. Casually he lifted the blanket to peek at my cock, which was refusing to go down and still stood out as hard as steel. He gave a low whistle. “Some people get the best lab accidents.”

“What?” I sputtered.

Expando let the blanket fall and focused on my face, smirking wickedly. “Just a bit of hero humour, Super Dick. You know, the whole origin of powers coming from lab accidents thing. Bet there would be plenty of guys wishing they could get results like this! So, what were you working on? Some sort of steroid Viagra? Or are you the one that keeps sending me those emails about how you can improve my penis size?”

“What? No!”

“Okay, clearly I’m not doing a very good job at relaxing you with humour,” Expando chuckled. “You’re just so tense, I’m just trying to help you relax. Here, will this make you feel better?”

The blue clad hero reached down and undid his belt. It had always been a thought at the back of my mind when it came to superhero suits if they were just a big Lycra onesie or a two-piece made to look like one. When Expando opened his belt I could see at least in his case it was the latter. Another question I’d often thought but never voice was about to be answered. Do superheroes wear underwear?

For Expando, the answer was no.

The rubberised hero rolled the lycra trousers down and pulled his cock out. He’d been completely commando in his suit, and his shaft was already rock hard as he stroked it in his gloved hand. It was a veiny, sturdy uncut 7 incher he was fondling with low hanging balls he let swing between his legs.

“There we go,” he said, still flashing his bright teeth in a cheeky smile, “now both our dicks are out! Well, mostly…”

Expando tugged on the silver blanket and I let out a spluttering moan as the material rubbed my achingly sensitive head. The blanket fell away and my dick bounced up, free from what little weight it had on my still solid shaft. The sensation ran down my dick, pooling in my balls and making them swell against my legs, pushing and forcing me to widen my stance. Expando didn’t seem to notice, he was too busy staring at my exposed dick.

“Super Dick, indeed,” he chuckled darkly. He was rubbing his cock, slowly now as he looked it over. “You know, Density always seems to think he’s the big, nice guy, but looking at this,” he ran a finger up my shaft, catching the trickle of pre that had oozed out, “looks like he’s been giving you a bad case of blue balls. And with balls as big as yours, I bet that can’t be comfortable.”

“It really isn’t,” I panted, my cock and balls aching for a release. My fucking balls felt like they were going to burst they were so full of cum. Seeing Expando shamelessly stroking himself was making me just want to grab mine in both hands and go to town. It would be a two handed job for sure.

“Want me to help?”

“What?” I gasped, struggling to think straight. “What do you mean help?”

“Well,” he said slowly, stepping even closer, my cock bobbing inches away from his chest, “I am a hero after all, and you clearly look to be in distress. And what is it heroes do? Help. Those. In. NEEEEED.”

He lowered his head and took my cock head in his mouth. The sensation of his hot breath rolling over my sensitive head was like nothing I’d ever felt before. It was so intense. And then when his tongue touched my flesh I swear I could feel every one of his tastebuds dancing over my nerves. His lips tightened in a seal over it and his cheeks caved in as he sucked at it. My knees turned to water and I almost collapsed. I heard something creaking, like balloons rubbing together or something, and then felt Expando’s arms quite literally wrap around me. He eased me into the arm chair gently and then withdrew his arms. I felt my bulbous nuts bump against the base of the chair, the hyper sensitivity letting me feel every fibre tickle my sack. I writhed in the chair, loosing utter control as my body forgot how to work, my brain forgot how to think.

Expando was on his knees in front of me, close enough that my nuts rested on his thighs as he expertly worked my shaft. His hands ran up and down the length, rubbing, squeezing and pumping it while his mouth focused solely on the head. I felt his hands stretch to better grip my thick cock, larger hands succeeding in encircling its girth and squeezing it harder. My head was spinning, I was gasping and panting for air as I had what was perhaps the best blow job I’d ever had.

After all these false starts, of getting wound up into a frenzy and then being left hanging all day, I didn’t last very long. My toes curled in their socks and I gripped the arms of the chair as my huge balls clenched and I felt the cum erupt. I closed my eyes as my vision blurred, heart tripping at the intensity of my orgasm, the flood gates well and truly opened as my cum factory balls emptied themselves with glee. I could feel Expando’s lips still round my cock, hands holding tight as he swallowed it all down.

Time lost all meaning, each shot felt like both an eternity and a fleeting second I couldn’t hold onto. I managed to claw myself back into some semblance of control, enough to open my eyes and see that my cock was shrinking. Expando was following it down as it retreated back into my body, mouth taking more of my cock the more manageable it became. Below I could see my balls were getting smaller as well, now no longer so full of cum they could return to a more normal size.

But the smaller my balls got, the bigger Expando’s belly was getting. While he still sucked and worked at my cock, I could see his belly filling up with my cum. His once flat, toned core was filling up like a blue water balloon. It bounced and jiggled as he dropped down lower, his own cock poking at its underside.

Finally my balls ran dry and Expando released my cock with a wet pop and a deep gasp of air. Strings of my jizz still stretched between his lips as he gulped in air, trembling tongue coated in thick cream darting out to lick the remnants from his lips. He leant back, falling onto his butt and sprawling against the low coffee table behind him, resting against it and having to spread his legs to accommodate his bloated belly. I couldn’t take my eyes off of it, the size of it, the way it jiggled with his movements and rippled with his breaths.

“Wow,” he gasped, rubbing his jaw and wiping his chin with the back of his hand. “Wow wow wow. That was a lot of cum, Super Dick. Fuck me,” he laughed, grabbing his cum belly in both hands and feeling it. “Look at this! Hahah!” he jiggled it and caressed it gently. “It looks like that time I swallowed a basketball. It was a dare, don’t ask. And hey, look, this must be your alter ego, Bruce Wang.”

Managing to pull my eyes off of the belly I’d given the giddy superhero, I looked down at my cock. It poked out from the tails of my shirt, shiny with Expando’s saliva and my cum, no longer the monster it was but still bigger than my usual. It was about 8 inches, slowly softening to 6 which had been my max when hard. My balls were no longer grapefruits and resting on the edge of the chair rather than hanging off like they’d been before. I was relieved. Having a big dick sounded all well and good but that had been a bit too big for comfort.

“What the ever-loving fuck!”

“Oh shit,” mumbled Expando, covering his mouth as he burped discreetly and tried to roll onto his feet and pull his trousers up at the same time. “Hey Density!”

Density was standing by the entry way, lips curled back and teeth bared. The tendons in his neck were taunt and rigid. He looked like pissed off personified. Watching Expando wobble onto his feet and struggle to do his belt over his cum gut didn’t cool the purple hero’s temper. In fact it looked more like it was adding fuel to the fire.

“No need to thank me,” Expando said, giving up on his belt and leaving it open. He had at least put his dick away. “I’ve managed to help your little friend here. Turns out he was just pent up!”

Density marched into the room, bearing down on the bloated hero who scuttled back until his claves caught the table, trapping him.

“You grassed on me!” Density growled, looming over Expando, muscles straining against his suit. “You told the Board I brought Steve on site because you knew they would haul me out to tear me a new one so you could slither in here!”

Expando pulled a face, twisting his mouth and quirking his eyebrow in mock confusion. “Huh? Me? Why would I do something like that? I mean, you brought a civilian onto the premises without authorisation, and then left him alone. Should I have kept it quiet? Should I have left him here unsupervised? That wouldn’t be very safe now would it?”

I could feel anger coming off of Density in waves. I discretely pulled at my shirt and crossed my legs, trying to hide my nakedness. The movement caught Density’s attention though and his head spun on me so quick I was surprised he didn’t get whiplash. His stare practically struck me and pined me to my chair. Seeing my startled expression was like a water bomb on his fiery rage and the tension left him instantly.

“I’m so sorry about this” he said and then added through gritted teeth, “he’s right. I should have done things better, and I shouldn’t have left you. And for that I’m sorry.”

“Good, well now that’s settled I’ll just—”

Expando had stretched one of his legs around Density in an attempt to step past him, but the larger hero stopped him with a solid hand to the chest. The stretched leg snapped back to normal as Density encroached further on Expando’s space. He jabbed a finger at the cum belly between them. “The apology was for him, as for you, I’ll deal with you later.”

“Promises, promises,” quipped Expando, though there was a slight waver in his voice. He gave Density a nod and stretched himself round the human blockade and made to leave. “I’ll see you around later Super Dick” he said, giving me a wink and tapping his finger to his head in a salute. “If those balls need emptying again, just give me a—”

His voice trailed off and he stopped in his tracks. He was looking down at his belly, hands coming up to stroke it. I could hear it gurgling from across the room. Expando gave a grunt.

“Are you okay?” I asked, standing up and moving with Density to approach the confused looking hero in blue as he turned back to face us.

“I… I don’t know,” he said, his usually buoyant voice uncharacteristically flat. “My stomach feels…weird.”

“Probably because you’re full of my spunk,” I said.

“While I admit it’s a lot of cum, I’ve seen him fill himself with a swimming pools’ worth of water” said Density. “This shouldn’t be causing you any discomfort Expando.”

“Yeah, well it is!” he snapped, just as his belly gave another load gurgle. He groaned and gripped the squishy tummy. “Ah fuck.”

Suddenly Expando’s belly began to retract. It deflated beneath his hands until his stomach was once again flat. He straightened up, blinking in confusion and running his hand searchingly over his abdomen, as though trying to find where his belly had gone. “Huh. I guess I… digested it?” He snapped his belt back together and then lifted his head to look at us, shrugging his shoulders.

Density began to say something but we both saw something happening to Expando’s chest. His firm chest was filling out, the pecs steadily bulking up within his suit, stretching the low neckline. His shoulders too were starting to thicken and grow, becoming shapelier and more sculpted.

“What are you two staring at?” he asked, his neck thickening and traps rising up like little boulders. He looked down, seeing his chest sticking out more than usual as his arms began to thicken and his biceps and triceps inflated. His eyes widened as well, but in shock rather than growth which was spreading rapidly through the rest of his body. The once lithe hero was now rapidly approaching Density’s level of bulk with no signs of slowing.

“What the fuck?” he breathed, feeling his stomach as abs popped out like little bricks, pushing out against his suit which clung to him and hugged their rising shape. The sound of stretching rubber was becoming louder as Expando continued to grow bigger and bigger.

“Expando,” said Density, “stop messing around.”

“I’m not doing this!” the growing hero squeaked shrilly, his legs rapidly thickening as the heads of his quads rose up into that seductive tear drop shape. His claves bugled and grew thicker as well and not only that but his crotch bulge was joining in on the growth as well. The front of his trousers was now drooping with the weight of his inflating package. I could see the three orbs of his cock and balls getting bigger and bigger, the shaft getting curled up and rising upwards. His quads shuddered thicker and pushed his package out even more.

Expando was becoming incredibly wide now, his whole body just so pumped up with muscle bulging everywhere I looked. His arms were as thick as footballs, pecs a dense shelf of muscles, his nipples looking fat as they poked visibly against his suit. His forearms were easily thicker than Density’s legs now, his lats pushing out against his arms to make them hang at an angle. As much as Expando was growing, it was only affecting his muscles. He wasn’t getting any taller, just amazingly buff and swole. The various muscles were staring to impeded Expando’s movements though, every muscle on his body battling it out for space, determined to take up as much room as possible.

“Oh fuck,” Expando breathed, but he didn’t sound afraid, he sounded…turned on. “Fuck yes, more, more! Keep getting bigger!”

His cock sprang out with a sudden lurch, startling Density and I into taking a step back. I could see his dick getting fatter and thicker, starting to grow a lot quicker than the rest of his body. I could see it growing against his suit which managed to stretch with the growing member and hug it like a second skin. I suppose his suit was designed to match his stretching powers so it was used to matching him no matter what he did. His balls were rapidly inflating as well, dropping down to knee level and swelling into beachballs. I watched, enamoured as his cock began to rise as he started getting hard, it was even bigger than my cock had been.

“You see that?!” Expando laughed, struggling to bend his insanely thick arms to touch his shaft, but the ample pecs bulging out and his wide lats kept his arms out and biceps and forearms were refusing to back down from each other all acted against him. “Guess I’m Super Dick now huh?” he laughed and grunted, bucking his hips to make his cock bob and sway in the air. “Although I’m surprised I can see it at all past these pecs!”

It was true, Expando’s head was almost lost within his pecs and traps, the latter rising like mountains on either side of his head, brushing his ears, while his pecs pressed against his dimpled chin. He was grinning though, eyes alive and sparkling as he struggled to take it all in, look at himself in all his swollen, muscular glory.

“Ah fuck it’s so tight! Fuck I’m so big, so full. Fuck, fuck, fffff-f-f-f-fuuuuuck!”

Expando’s entire body shook and flexed, his balls bouncing as he came. I could see his suit darken around the head of his massive cock, the cum trapped within the suit like a giant condom. With nowhere to go the splooge filled up the already fully packed crotch, the suit no longer hugging the shaft to show off every bump and crease, the layer of cum softening the edges as it sloshed and churned within.

“Oh fuck, oh fuck me!” Expando gasped. “Oh fuck that was amazing. Oh fuck, so much cum, fuuuuuck!”

Density and I were speechless. We could only stare as Expando writhed before us; a muscle blimp packed so full of massive muscles he looked like he could hardly move. And then there was his massive dick jutting out about 4 feet in front of him, and his balls approaching yoga ball size now and almost touching the floor. He had stopped growing at least but was still lost in the euphoria of his orgasm. It was a wonder he hadn’t toppled over, but I guess all that muscle made him sturdy. His breathing slowly returned to normal, pecs tensing together as he tried to get himself back under control. I could practically see the cum sloshing around his dong, probably running down to pool around his balls as well. His cute face, nestled between his traps and pecs had a goofy grin plastered across it, eyes sparkling as he looked over his body.

“So buff,” he moaned. He manage to move his arm, twisting it enough to raise the forearm, wrist bending as though he was flexing. The rest of his arm hardly moved, except the the bicep bulging even bigger, too big for him to bend. “Huh,” he laughed, “might need your guys help if it get an itchy nose. Can’t bend my arms I’m too big.” He tensed and relaxed his arms a bit and then brought them together…or at least tried too, biceps and pecs squashed together, forcing his head back as his thick chest bulged against his chin. “Even then,” he grunted, still flexing, “you’d probably have to climb up these pecs to reach my head!”

“Can’t you just stretch?” I asked, although really I’d quite happily volunteer to climb into that chest.

“Oh yeah,” Expanding chuckled, “I was so distracted my all this fucking muscle I forgot! Bet a few extra inches will give me a bit of mobility back.”

Expando lifted his arm again, finger pointing to his face. He strained and grunted, and for the first time his grin faltered. He opened his hand, shaking and flexing his fingers and then tried again. Still nothing. What little movements the muscle blimp could make were becoming more frantic and he looked in danger of toppling over.

“I can’t stretch!” he cried. “I can’t use my powers!!”

It was still incredible to see how big my cum had made Expando. He was still the same height of about 5’11”, but the width of his shoulders was greater than a door frame. Add to that the width added from his swollen arms hanging at about 45 degrees at his side made him look like wider than he was tall. If he could have walked I doubt he could have used even a double door without maybe going through it at an angle. Even then, it would take a bit of manoeuvring to direct that 4 foot penis jutting out from his hips as well.

The hotness was somewhat marred, however, by the hero’s attempts to stretch his already full body a few inches to allow movement. His pumped up arms were flailing and rubbing against his pecs and lats as the various muscle groups fought for space.

“Be careful!” snapped Density. “You’re going to fall over at this rate. And I’m not sure the floor could take it.”

Expando’s handsome face twisted into a scowl. “Don’t tell me to calm down,” he said, his suit creaking as he flexed and stuck out his dimpled chin. “Right now I bet I could put you through a wall without you needing to phase through.”

“Yeah, maybe if you fell on me.”

Expando swore and tried to take a step forward. He was hampered by… well, quite a lot at a guess. His legs were already spread to accommodate thighs thicker than Density’s chest. He would have needed more than a bodybuilder roll to get one quad over the other. If that wasn’t enough his yoga ball sized nuts resting on top of those titanic thighs made it nigh impossible to take a step forward. Yet Expando was determined to try.

His cock swung and his balls sloshed to the left as he pivoted and managed to lift his right leg. I felt the floor tremor when it landed, but I also saw the look of triumph on Expando’s face turn to one of strain as his cock and balls swung back the other way. I could see all his muscles tense and flex as he tried to hold himself up right. Instinctively I moved forward to help, going under his arm to help him find his balance.

I regretted it immediately.

His arm was so fucking heavy! His biceps alone were as big as my head, adding in the triceps and forearms it felt like a person on its own. His pecs were a strange mix of solid muscle and soft skin beneath the Lycra, his nipple rubbing against my cheek and ear as I tried with all my might to push him back up. I doubt I contributed more than maybe squashing his pec slightly, but thankfully Density came to my rescue again before I pulled something. With a grunt he first pushed with one hand on Expando’s chest and the other barely covering his biceps, then once he was off of me Density ducked in to take my place. I moved out of the way, stepping back and getting the first glimpse of the muscle blimp’s backside.

His back was like an aerial view of a mountain range; the swollen peaks and deep valleys running between them, the way they rippled and flexed as Expando wiggled his arms. His triceps were swollen horseshoes, the swell of his biceps just visible beyond them while his wide lats pushed at them too. I could probably spread my arms and just get my hands over each lat but fuck if I could manage more. And then the way that wide expanse suddenly tapered down, sweeping in to his tight waist. From the front I couldn’t see much of his core, what with his low hanging pecs and the massive cock getting pushed up by his quads and balls, from here I could see just how tight and narrow his waist still was. Then just below that his body swelled out again into the biggest backside I had ever seen. It was like a pert shelf of glutes, thick enough I could probably sit on it, each cheek easily wider than a gripping hand could cover. My still bare cock twitched beneath the tails of my shirt.

“I’m fine, I’m fine,” grumbled Expando. I could see him shuffling his feet to get them into position to better support his weight. “You can let go now.”

I realised I’d missed out on checking Density’s backside, just catching a glimpse of the purple speedo before he vanished in front of Expando. If it wasn’t for their difference in height, I would have lost sight of Density completely. As it was I could see his scowl over the ridge of Expando’s traps.

“So as I expected, you can barely walk.” Exasperated, Density ran a hand through his dark hair, leaving his arm behind his head as he struggled to think of what to do. “Even if you could walk you’d probably get wedged in the hallway, let alone fit through the door.”

“Cos I’m extra thicc,” Expando chuckled. “Bet I could give a little flex and the walls would give way for me anyway.”

“And how do you propose you could get there?”

Expando twisted his head, struggling to see over his traps to look at me. “You going to come round and join the conversation Super Dick or are you going to fuck me or something? Although unless your dick has grown again I doubt you could get past these cheeks.” Showing off his control, Expando made his butt cheeks bounce and ripple enticingly and my cock started to chub up. I tried to tuck it under my shirt, thinking I must be a sight walking around with nothing on my bottom half but my socks and my shirt barely covering my junk.

As I ducked under Expando’s arm and came back to stand in front of him, I could see his lusty eyes staring hungrily at my cock. “Did you enjoy the view?”

“Give over,” grumbled Density, but I caught him staring at my dick too.

“Don’t be jealous, I look fucking amazing.”

“You look like an over blown muscle balloon.”

“Why, thank you.”

“Aren’t you worried about your powers not working?”

Expando snorted, flexing his whole body, pecs bulging against his chin and traps swelling up around his head. “Who cares about stretching, I like this kind of expansion better! Hey Super Dick, want to be my sidekick? Just stick your cock in my mouth and make me swell up over the bad guys!”

“What? You can’t be serious,” Density scoffed incredulously, “you can’t possibly want to get any bigger!”

“Why not? It felt incredible swelling up, and just feeling my muscle rub against each other with the slightest movement is keeping me hard. And speaking of hard, have you seen my dick? What am I saying, of course you have. One, it’s too fucking big to miss and, two, you’re a size queen.”

“We need to get you out of here and down to Watcher’s lab,” said Density, ignoring the blimp’s jibes. “Steve, I’m going to take him from behind—”

“That’ll be a first” mumbled Expando.

“—if you try and keep his dick under control. Shame we can’t shove it in his mouth to keep him quiet.”

“Suppose that is the only downside to this, can’t suck myself up any more.”

I approached the massive 4 foot cock and wondered how best to handle it. It was thick, but when I bent over it and wrapped my arms round it, I found it was possible. Expando gave a quivering moan as my embrace made the cum still trapped in his suit slosh round, not to mention the way my hands rubbed the underside as I tried to find a good grip probably stimulated things as well. With Density’s help to keep his balance and me gripping his cock to keep it from swinging uncontrollably we started the process of turning him around to face the hallway.

Despite myself I couldn’t help but bone up at handling such a massive dick. I’d thought mine was huge not that long ago and now I was comfortably hugging a penis. I think Expando could feel my hardon poking his, the way he was moaning and grunting as our motions made me almost grind against it. It felt really good, so much so I think I stated leaking pre, but I couldn’t take the time to check. Density was determined to keep up momentum.

“Nearly there,” he grunted as he helped Expando lift a leg and take one tiny step forward.

“You’re doing great guys,” Expando giggled, although it turned into a wavering moan as I tried to shift his balls for another step. “You especially Super Dick. It’s so cute the way you just disappear under my pecs like that.”

I looked up from my position, crouched down with the hero’s nuts filling my arms and his cock slung over my shoulder, throbbing warmly against my cheek. His pec shelf completely blocked his face, and when I leant back, I could just see his smirking face looking down at me.

“There you are,” he all but purred and I felt his dick twitching beside me.

“Lift, Steve,” Density barked.

“Sorry,” I mumbled, ignoring the tingling sensation in my nuts as I got back on Expando’s.

After a few more grunts and tugs we’d managed to get Expando to the mouth of the hallway. We took a moment to try and form a plan, but I was beginning to think it was doomed to fail from the start. I was in front, standing the the hallway, Expando’s cock stuck out before me, using it to hide my own erection. I could see Density looking over Expando’s trap, frowning at the close proximity of his mighty chest and the hallway walls. I could hardly see his arms. Meanwhile Expando himself was still grinning from ear to ear, ever so slightly rocking his hips so his dick would rub pleasantly against mine. I found my hand going to rest on his head, rubbing at the underside to tease the glands, making his grin wider and his eyes roll in bliss.

“Let’s give it a go,” said Density, getting into position behind Expando’s back and ready to push. “We’re going to have to go in at an angle, and maybe you will have to break the walls a bit.”

“Fine by me,” smirked Expando. He winked at me. “Tug away, Super Dick.”

I wrapped my arms around his cock again and helped keep it under control as Density pushed and Expando lurched. He stuck his left arm forward, getting it trapped between the wall and his pecs. The plaster crackled and bowed against his bulk. I heard Density grunt as he pushed again, heard the walls creak as Expando’s bulk filled the space.

“Fuck,” Density grunted.

I lost my footing and fell against Expando’s dick, making him cry out in pleasure.

“What is it?” Density asked.

“Nothing,” said Expando quickly, looking down at me and winking. “Just keep pushing and I’ll try and get through.”

Expando rocked his hips, making his dick poke against my groin. I could feel my cock rub against his spongy mushroom head and had to suppress a moan myself. My dick throbbed all the harder, pushing back at the much larger one and begged to rub back. Biting my lip, I gripped Expabdo’s cock head and ground my shaft against his. He nodded, eyes closing as he too tried to keep quiet, grunting as he began to buck his hips more vigorously.

I got knocked into the wall by his thrusts, struggling to cling onto his dick, my grasping only rubbing it more vigorously for him. The fat head of his dick kept pressing against my whole shaft, almost kissing it. It felt soooooooo fucking good, my junk tingling all over with pleasure. With a start I realised that tingling sensation was familiar and looked down.

My dick was growing again. It was shiny and slick with pre as my hips rolled to continue humping myself against the massive Lycra covered cock. A small part of me knew this should be cause of concern…but the sensation just felt so good. I could feel my balls rubbing more and more against my thighs as they too joined in on the growth. It was as though I could feel them filling up with cum, producing more and more of it based on my aroused state. I gripped Expando’s cock head harder, rubbing at it more vigorously, causing Expando to groan out even more.

“What the fuck are you doing?” I could vaguely hear Density complain. “You’re hardly helping at all, Expando, stop bucking your hips and suck in your chest or something.”

“W-w-will do,” Expando stammered. “I’m ssssooo close. So close. Keep doing what you’re doing, Super Dick.”

I could feel my balls swelling up rapidly, slapping against my thighs and Epando’s cock head. My own cock head was now travelling up my torso, slapping against my chest with my motions. It kept swaying close to my face and I found my mouth opening, tongue searching to make contact. It started smacking against my lips and I felt my knees start to shake.

“Oh yes, come on, come on, almost there” chanted Expando. “See if you can aim it this way!” he laughed, opening his mouth wide.

“Aim what? What are you talking ab—Steve, no!!”

I had just lapped at the pre oozing from my slit when a hand grabbed me by my collar and yanked me backwards. I lost my grip on Expando’s cock just as I heard him grunting and crying out.

“Fffffuck!!” he roared.

I didn’t see what was happening but from the noises of bliss I guessed he was cumming. Meanwhile I was splayed out on the floor of the main corridor, my dick throbbing in fury at being denied release again. My balls went painfully tight as they bloated up with unspent cum. I was ready to take my meat in hand and beat it myself to relieve the pressure, when I noticed the figure standing over me.

First I noticed the sturdy, sculpted legs stretching up either side of my head. They were covered in red Lycra, so tight I could see every head of muscle on his thick quads. Then there was the generous bulge at his crotch. Beyond that I could see abs and chest, bare of any super suit covering apart from what looked like a leather harness strapped over his full chest. The skin was a dazzling bronze, almost appearing to glow with its own inner light, with blond hair peppering the abs while coating the chest more vigorously. Looking beyond that chest I could see a chiseled jaw beneath a metallic golden mask which looked like the sun, the wavy sunbeams creating a crown like affect. There was the cascade of luxurious blond hair, it was more like gold and glowed even more so than his skin, and finally a set of crimson wings creating a halo of sorts.

“Who are you?” he demanded, his voice deeper than Density’s and not a glimmer of humour that sparkled Expando’s words. “How did you get in here?”

I couldn’t find my voice as I scrambled to my feet, fumbling with my balls and cock. I tucked my chest high hardon up my shirt in an attempt to keep it out of the way, though I doubted it did anything to improve my appearance. I still had nothing below the waist apart from socks and my nuts were still swinging free around my thighs. “I Erm…I am…erm…my name is Steve,” I said somewhat lamely.

The hero I now recognised as Icarus folded his arms over his powerful chest. He tilted his head to look round me, drawn by the gasping sounds of fading pleasure as Expando revelled in his afterglow. After giving me one more piercing look, Icarus pressed something on his harness and his wings folded in, somehow disappearing behind him. He then moved around me to peer through the doorway. Curiosity got the better of me and I followed to have a look.

Expando was still wedged in the hallway, pecs heaving as he gasped for air after his intense orgasm. Cum had leaked out of his low neckline, the suit around his dick looking bloated with the rest of the cum that was still trapped inside. The material had darkened even more from the abundance of spunk, but still managed to keep it inside. Just over Expando’s swollen trap I could see Density frozen like a deer in the headlights of Icarus’ gaze. Expando recovered first.

“Morning, Icarus,” he panted, still trying to catch his breath. “Could you tell me if there a cute guy with a massive dick under my even bigger dick? He was there a second ago, I can’t feel him and as you can see my vision is somewhat compromised of anything too close.”

Without looking, Icarus grabbed me by the collar and hauled me into view. Expando’s eyes brightened and his grin grew. “There you are, Super Dick. No use trying to hide your cock under your shirt, glad to see you haven’t blown yet. Why don’t you undo a few buttons, come here and shove it in my mouth. I’ll help you out again and you can watch me grow even bigger!”

“Shut up, Expando!” growled Density.

“You did this to him?” Icarus asked me. His voice was oddly cold considering his body seemed to be radiating heat now I was so close to his bare skin. “Your erm…semen caused him to grow?”

“It was the Body Builder, Icarus,” Density cut in. “I think he had some kind of reaction from the formula and now—”

“Come out here Density,” Icarus grunted irritably. “Phase through the walls so I can see you properly.”

“Sorry, am I blocking the way?” Expando giggled. “But come on, I’m a way better vi—ow!”

Density smirked as he disappeared further into the room and then after a few seconds stepped out through the wall and into the corridor. His eyebrows lifted when he saw me with my dick stuffed up my shirt but quickly gave Icarus his full attention.

“Well, at least you’re still in proportion,” Icarus said, giving his colleague the once over with a critical eye. “Anything extra in there or are you just enjoying yourself?”

Density’s cheeks coloured as he put his hands over his crotch, hiding the boner he’d hadn’t quite tucked away properly. “Sorry, Expando was making such a racket and—”

“Oh shut up!” Expando yelled from out of sight. “Just because you kicked my butt doesn’t mean I forgot how much you were fondling it.”

“Enough,” Icarus sighed with a resigned groan. “Why is Expando like that?”

“I blame his parents,” mumbled Density.

“Fuck you!”

“I said enough! Answers, Density. Now. Who is this guy and why is he on site? I’m ignoring the enormous genitalia for now but I will come back to it.”

Once Icarus had been filled in on the situation, I got the full brunt of his stare. My cock twitched guiltily against the confines of my shirt, still rock hard, refusing to go down and oozing pre constantly. Despite the situation, seeing Density in his skintight uniform and Icarus with his bare torso rippling with every motion, I couldn’t help but admire their musculature which kept me hard. I’d always had a thing for muscles, but it had never been this bad where I couldn’t calm myself down. Then again, my dick hadn’t been able to reach my chest before today either.

“This is all a bit beyond me,” said the shirtless hero, stroking his strong jaw in thought. “So it’s clear this guy’s semen caused Expando to bulk up. The fact he was shot with one of the Body Builder’s darts is clearly at the root of this, however I don’t understand how that’s caused his testicles to replicate the bulking formula.”

“Well, Steve, you’re a scientist,” stated Density. “The Body Builder was after your partner, so you must have been working on something he was interested in. Could that have caused you to react in this way?”

I shook my head. “We were working on cancer treatment, hardly something a super villain would be interested.”

“What kind of treatment?”

“It was based around the idea of promoting healthy cell growth to increase recovery.”

“Growth?” Density echoed.

I shattered his ‘eureka’ moment with a shake of my head. “Just because I said ‘growth’ doesn’t mean this is what we were aiming for.” I gestured at my dick still throbbing under my shirt. Part of me was fantasising what it would be like for Density and Icarus to come up either side and grind their great pecs against it. “It was strictly at the cellular level, nothing to effect testosterone production or increase of actual muscle mass.”

“Well, we’ll put the ‘why’ to one side for now,” said Icarus, “perhaps we should look into how to reverse the effects. The Body Builder’s formula has never lasted very long before and yet by the sounds of it Expando’s been like this for a while. Did you say your penis shrank back down after you ejaculated?”

I nodded, remembering how Expando’s lips had felt around my sensitive head. How my dick had shuddered with every shot of cum and shrank down, having emptied my nuts and filled Expando instead. “Yeah, it didn’t go back to normal, for me I mean, but at least it was manageable.”

“Then perhaps we should kill two birds with one stone. Collect a sample of your semen for tests and in doing so reduce your genitalia so they aren’t so… distracting.”

“I can help with that.” Density sounded very eager, shuffling forward in a way that reminded me of an excitable puppy.

“No,” Icarus said sharply. “We can’t risk anyone else ending up like Expando.”

“I’m fine!” the muscle blimp called. “I think I’m getting used to the mass now, I can move a bit better.”

The three of us came back up the doorway, looking in on Expando. He was still wedged in the corridor, cum leaking out around the low neckline of his suit. There was also a few sticky ropes of it on his fingers, as though he’d managed to fish some from his cleavage but had failed to bend his arm enough to get it to his mouth. “See, look,” he said, swinging his hips causing his colossal dick to smack against the walls with wet, meaty thwaks.

“Wait,” Density said, as Icarus made to turn away and ignore the phallic display. “Look at his chest, it’s not as tightly packed against the walls.”

I’d been so wrapped up in the idea of Expando trying to feed himself bigger off his of cum I hadn’t realised that Density had a point. While the rubberised hero was still plenty big and bulgy as ever, he wasn’t filling the corridor as much as he had before. Expando’s cocky expression cracked as he too started to realise he wasn’t as massive as before. “Ah shit.”

“I bet his cumming helped loose some size,” said Density. “Just like it did for Steve and his cock! Maybe if we get him to blow enough times he’ll shrink back down.”

“Do I have to?” Expando all but whined.

“Yes,” says Icarus bluntly. “You can help him out Density, I’ll take…”

“Steve,” I supplied.

“Steve somewhere he can relieve himself in private. It will reduce the risk of his radioactive semen making anyone else blow up.”

“What about Expando’s c… semen?” asked Density.

“Well considering he’s been stewing in it in his suit I think it’ll be fine. Just don’t let him eat it, just in case.”

“Are you sure you can’t sort Expando and I’ll help Steve…” Density’s question withered at the look on Icarus’ face.

“Let’s take you somewhere quiet,” Icarus said, gesturing for me to walk on.

With as much dignity as I could muster, I waddled forward, being mindful of my nuts bumping against my thighs and my cock rubbing against my shirt in a heady mix of discomfort and pleasure. I weighed up the idea of letting it out but thought at least in the shirt it was more out of the way than letting it swing.

“I’m waiting,” I heard Expando say in a sing song voice behind us. “I know you’ve been wanting to ride his dick all morning, why not give mine a go.” I couldn’t hear Density’s reply, but whatever it was it made Expando giggle. “Yeah yeah, put those arms to good use and pump this beast for me.”

The moans of pleasure slowly faded, but not before they put images in my mind of Density wrestling with Expando’s massive dick. How would it feel to have those sculpted arms encircling his shaft, squeezing it and surrounding it with muscle. I really wished I had Density to help with my dick, as nice as it was to see Icarus’s full chest on display bulging against his straps, I doubted he’d be willing to be as hands on as Density would have. I remembered his kiss fondly, sending a jolt of pleasure through my groin and making my balls feel full and heavy.

“Shit,” I moaned, I could see my shirt darken as my cock head flared and a copious amount of pre oozed out. I couldn’t tell if it was my imagination but it was hard to tell if my duck was just throbbing or if it was growing as well.

“Be careful,” said Icarus, eying the floor for any drops of pre I might have left. He looked around and took me by the arm, making me walk faster towards the lift. As we waited, I couldn’t help but eye his nipple which was tantalisingly close. My mouth watered and I had to swallow, tongue longing to roll over it, in spite of the chest hair I’d undoubtably end up having to pick from my teeth. The lift doors opened and he dragged me in.

While he pressed the buttons for a lower level, I caught the first glimpse I’d had of myself after my change.

I looked short next to Icarus, my legs twig like and arse pancake flat compared to his tights clad excellence. But then there was my cock and balls. Both my balls were about the size of a football resting a top my thighs, and the dick up my shirt was so obscene. The tails of my shit just brushed the top of my sack while the shaft pushed at the buttons further up. The cock head looked like it was struggling to break free of my collar, and having it so close to my face was proving to be almost too tempting. I remembered in my youth trying to suck myself off to no success, but now it would be just a case of leaning forward and guiding my cock into my waiting mouth. The slit stared back at me as I looked down at it, licking my lips.

“Hurry up,” Icarus grumbled, jabbing the buttons. Coincidentally they did open and he ushered me out into another corridor, this one a lot darker and colder, causing me to shiver as the air ran up my sack. He grabbed the first door and pulled me into a vacant room.

It had the same layout as Density’s upstairs, if a little smaller and this one completely devoid of furniture. It was even colder in here and Icarus’ footsteps echoed loudly off the bare walls. “There’s a bathroom in there,” he said curtly, “do your business and aim for the tub.”

And with that he shoved me into a tiny bathroom, closing the door promptly behind me. I rubbed at my arms, looking over at the untouched and somewhat dusty surfaces. It was clear these rooms had never been used. My cock gave a painful throb and I decided to stop worrying and have a much needed wank.

I unbuttoned my shirt and chucked it into the basin. I then removed my socks despite the cold because I felt like a twat walking around in noting but them. Once completely naked, I touched my dick.

It was so sensitive. I shuddered from the intense pleasure just stroking the tight skin brought me. It was as though I was being punished for ignoring it for so long. I needed both hands to circle the beast, squeezing it between them and feeling it pulse and throb against my grasp. Despite how pent up I felt, I still took it slow, loving how it felt and wanting to stretch it out just a little bit. My cock was so eager however, it didn’t take long for my head to flair and a copious amount of pre oozed out and dribbled over my fingers.

Remembering I was supposed to be cumming into the bath I turned round and started to push my shaft downwards. I hesitated however, my one eyed trouser snake staring back at me, the idea of giving myself head drifting back to the forefront of my mind. My pre slick fingers glided over the head and I felt my balls lurch and swell with building arousal. My other hand absently reached down to stroke the swollen orbs, looking down at the rest of my skinny body. I began to wonder what I would look like with some extra muscle to go with this massive cock…

I mean, it couldn’t hurt right? Just a mouthful would do. It’s not as though I couldn’t leave a hefty sample with these massive nuts, they’d hardly miss a mouthful.

Before I could change my mind, I wrapped my mouth around my cock head. It was pretty wide, the head alone easily filled my mouth. I gripped the middle of my shaft, holding it close as I tried to take more, but it was a bit thick for my unpracticed throat. I blamed it on not having sucked a cock as big as mine before, which made my balls bulge out that little bit bigger. My dick was bigger than any guy I’d been with, I was so big I could suck myself off and my pre tasted sooooo good. I couldn’t get enough as it filled my pallet and slipped warmly down my throat. I began to stroke my shaft more vigorously, hungry for the real thing, to maybe get big enough muscles to fuck my own pecs! Fuck I wanted to fuck Density’s chest so bad.

A low moan left my throat as my balls clenched. I gripped my shaft tighter and pumped it for all it was worth. I swear I felt that first shot travel up my dick, as hot and fierce as lava erupting from a volcano. The head flared in my mouth and my cheeks bulged with the massive load. I wrapped my lips tightly around it, sucked and swallowed, only managing to get a portion of it down. The next shot came before I could finish the first, filling my mouth again. I gulped, but the next one was already surging. I hadn’t expected there to be so much and for my cum to be so thick! As I swallowed and swallowed, my mouth almost overflowing with cum, I realised I was only supposed to have had one mouthful. I lent over the bath, releasing my cock with a wet plop and then tried to push it down to aim for the tub. It was so hard, both hard to aim my dick and my dick itself so solid it was a struggle to go down. Volleys of spunk spattered on the tiles, coated the taps and pooled on the edge before I managed to get the monster under control.

“Oh shit,” I panted, cum dribbling on my chin as I saw a bit of a roundness to my belly. It wasn’t as prominent as Expando’s had been, just like I had a food baby after a heavy meal. That was more than one mouthful. My last few shots were somewhat marred by a sliver of dread at the thought of how big I was going to get. It wasn’t the growth I was worried about, so much as Icarus would probably be pissed off.

I massaged the last drops of cum from my massive dick, waiting for it and my balls to go down. I was rubbing my hand over my cum slick head, brining my sticky hand to my face to lick them clean. In for a penny, in for a pound, and not as though it would make that much of a difference.

The cum in my belly churned when my cock didn’t start shrinking. When Expando had sucked me off, it had practically shrunk with every shot until it was more normal sized. Now it was still as big as ever. What if it didn’t go down? What if I was stuck like this now? What if—

“Fuck!” I gasped in shock as the most incredible heat washed through my nuts. I groped them, feeling the firm flesh start to push back, expanding bigger and bigger. They swelled between my legs, upsetting my balance as they went from footballs to basketballs and still growing bigger. I grabbed at them, holding them close as though hoping I could somehow stop the growth by pushing them back in, but the cum bags just bulged against my hold, spilling over my hands as they reached beachball size and still kept growing .

“Everything all right in there?” Icarus asked from the other side of the door.

“My balls are growing!” I cried back, turning round to head for the door. My growing nuts sloshed and swayed, unbalancing me. I fell into the side of the bathtub, sitting on the edge as my balls gave a violent lurch and swelled even bigger. My legs splayed out and they dropped past my knees, reaching against my calves as I was forced to man spread. I could do little as I perched on the edge of the tub, watching my nuts swell and drop towards the ground.

A tingling sensation in my dick brought my attention up in time to see it too was joining in on the growth. The shaft throbbed thicker and longer, pointing towards the door. My mouth dropped as it grew across the length of the little bathroom, my head kissing the door while I was sat on the opposite side of the room. I placed a trembling hand on it, head spinning at how little my handspan could cover it, my palm resting comfortably on the top. No way could I grab it, not even with both hands. I could probably only just get my arms round it at the point.

The bathroom was starting to feel a bit cramped as my balls now touched the floor, swelling hotly against my legs and feet while my cock pushed at the door, sliding upwards as it kept getting longer, getting thick enough to rub both the basin and the toilet. I felt the vibrations of the wood as Icarus knocked.

“What was that?” he called from the other side. “What’s wrong with your balls?”

“They… they’ve grown again. My dick too!”

“What? I’m coming in.”

“No, wait!” I called, almost falling in the tub when Icarus pushed at the door. It was a testament to just how hard my dick was that it halted Icarus from opening the door fully. My head slid up the door, but the middle of my shaft pushed against the underside of the basin, keeping it from going anywhere higher and blocking the door way. “Ouch!”

“What’s that?!” Icarus yelled.

“My dick!”

Icarus pushed harder against the door, enough to stick his head in. I saw his eyes widen when they took in the massive, throbbing shaft jutting from my groin. It had to be about 5 feet long to cover the bathroom, bigger than Expando’s had been.

“Super Dick indeed,” Icarus breathed.

Gently, he squeezed an arm in, reaching around to try and push my dick further along to get in. His hand was deliciously warm, unnaturally so. It felt really good on my super-sized and super sensitive cock. The head moved to the edge of the door, getting squeezed between it and the wall. I let out a mingled cry of pain and pleasure, causing Icarus to curse and scramble.

“Sorry,” he grunted, squeezing in through the narrow gap. He managed to get in, almost falling over the toilet as my cock throbbed and pushed the door closed. “Fucking hell,” he breathed, looking along the length of my shaft to me perched on the bathtub. His eyes widened even more when he saw my balls resting on the ground. “How did this happen?”

“I erm… well I may have… accidentally got some cum on me,” I hedged. “It was hard to—I mean difficult to aim my cock.”

“And it only made your genitalia grow,” Icarus stated, taking in the lack of musculature on my skinny frame. His eyes appeared to linger on my bloated belly. He moved a bit closer, heat radiating off of his body in the tiny room as he peered into the tub. “I’m going to assume there was more in there. You forgot to put the plug in.” he said, wafting a hand in front of his face.

Blinking I twisted myself to look down at the slowly draining tub of cum, flowing steadily down the drain I had forgotten to fill in my haste to get off. Well, I was no doubt plummeting in Icarus’ eye even more now. Too stupid to remember to fucking put the fucking plug in.

“So how much did you get on you?” he asked.

“Erm… I don’t know.”

“Did you swallow any?”

“No.” I said, far too quickly to be believable.

“Uh-huh. Well, it’s just I find it odd that you grew this much from just getting your semen on you, when I have seen your python leaking constantly ever since we met. If it can run down the shaft of your penis and have no effect, why had it not caused more growth before now? And yet, a few misfires has caused this?” he patted my dick, his fingers intentionally or not drumming a beat on my meat that made my toes curl. My dick throbbed in excitement, part of it brushing against Icarus’ warm hip. “You drank some, didn’t you.”

It wasn’t a question. I couldn’t look at the glower of disapproval from behind the sun crown and instead lowered my gaze, taking in the sculpted bronze body standing next to my staggering dick. “Yes,” I mumbled.

Icarus pecs rose as he took a deep breath and sighed. “Hoping for a bit of muscle I assume?”

I nodded.

“Well, at least we know it has to be ingested to have any affect, so I don’t have to worry about where I step. That, and if we get you off now and you don’t eat it, we should be able to get you small enough to get you down to the lab.”

“We?” I repeated.

“Just to make sure you don’t feel tempted to have another sample. And,” Icarus jabbed a thumb over his shoulder at the door, “I rather have an easier time with the door.”

And with no further warning, Icarus hugged my dick. His thick, solid arms encircled my shaft, pressing his slabs of pecs against it too, surrounding my shaft in the warmest hug I’d ever had. My balls shuddered and swelled with arousal, my dick fattening up within his grasp as he slowly started stroking it with his upper body.

“Oh fuck,” I breathed, bracing myself against the tub as he worked my dick, almost pulling me from my perch. “Oh fuck! Why… why are you so hot?!” I sputtered.

For the first time, Icarus gave me a genuine smile. “Diet and regular exercise. Sorry, I don’t joke often but you’d be surprised at how often I get that question.” He tensed his chest and flexed his arms as he continued to stroke my massive shaft. “I’m essentially solar powered; hence why I go out with little on as is socially acceptable. I store the suns energy in myself to improve my strength, and it is stored as heat. I can also use that energy to run a bit hotter… like so.”

Icarus released the middle of my shaft, leaning over the toilet to put a hand on the underside of my cock head. He began rubbing it, his palm heating up and gliding teasingly over the tight, sensitive skin. My head was spinning, it felt so good, and I couldn’t believe Icarus was so enthusiastic about it all. Despite his warm skin I’d found his attitude towards me cold and distant. He’d told me to sort myself out before and left me too it, now he was more hands on.

“Fuck this dick is incredible,” I heard the hot hero mutter, pressing more of his body against it as he tried to get closer to the head. I could feel his crotch rubbing against my shaft. “Can’t believe how big it is, how great it looks, how it smells. Makes me wonder how it tastes, your cum? Was it good?”

I could only nod and make noises of agreement. I could feel his rough chest hair and the straps of his harness rub against me, a heady contrast to his soft, warm hands gliding over the head. He was trying to get to the head, practically going under my dick and trying to push me back so he could get between it and the door. I was hating how small this fucking bathroom was, pressing myself against the wall, balancing over the tub as much as I could while my nuts still rested heavily against the floor. I was trying to think of another position when Icarus managed to lap his tongue against my glands.

“Fuck!” I moaned, slipping and falling into the tub, legs going in the air, my nuts slamming against the side and getting pulled painfully. Icarus quickly took advantage as my cock slid back, to jump up, wrap his lips around as much of the head as he could and start lapping hungrily at the pre flowing. The strain on my nuts was too much for me, so I lifted myself back out of the tub, my cock almost smothering Icarus’ face. He in turn was pushed back against door, getting wedged in the corner of the room, my dick stuck over his mouth. His hot hands pawed at my shaft to try and push it off but it was only turning me on more. I felt my balls tremble, swell up tighter with cum just before I was pushed over the edge.

Fuuuuuck!” I roared as my massive nuts started to empty. Hot cum fired from my dick, flooding into Icarus’ mouth, perfectly positioned at the slit, who had no choice but to gulp it down. It was too much for him to take, cum leaking out of the sides of his mouth, dribbling down his chin onto his chest. He was soon slick with it, making his grasping attempts to push me off futile as he just kept sliding off. A small part knew I should have moved back, let him free, but his mouth felt soooo good. It wasn’t until my dick began to shrink down that Icarus managed to push himself free.

Tiny sticky threads of my cum still conducted his lips as he opened his mouth in a hungry gasp for air, eyes wide while he half-heartedly pushed my still jerking cock out of the way, even as the ensuing volleys rained down on him. My cock twitched and throbbed in the fading throws of my orgasm, each shot causing it to shrink as well. My nuts began to rise from the floor as they too began to empty. When I had finally stopped cumming, I’d only lost about half of my size, my 2 and a half foot cock drooping forward, almost touching the large puddles of cum on the floor.

The only sounds were mine and Icarus’ heavy breathing with a few wet splats as my cum fell from the walls and ceiling. And Icarus I guess. The front of his tights were darkened with cum, making them cling to a hefty looking dick. I actually blinked at the thickness of the monster the hot hero was smuggling, until my eyes travelled slightly higher.

Despite the difficult he’d had with taking my cock, Icarus’ abs were distended with the amount of cum he’d swallowed. His previous flat, tight core had swelled into a bit of a gut, the muscles somehow still there giving it the appearance of an armoured tortoise shell. Icarus brushed his cum slick hair back, looking down at his cum filled belly in shock before his terrified eyes found mine.

“What did you do to me?”

Almost falling in his haste, Icarus wrenched the door open and fled back into the room. His footsteps squelched as he left cum covered footprints on the floorboards. Not sure what else to do, I followed after him, after taking a futile second to cast my eyes over the bathroom for something to cover myself with. Even if there had been towels to hand, they would have been drenched in cum. I couldn’t even see my clothes, no doubt buried under the cum.

I found Icarus by the window, staring at his distended belly bathing in the sunlight. When he heard me approach, his head whipped round and his hand lashed out with an accusatory finger. “You stay there!” he snapped, scowling when he noticed cum was dripping from his pointing finger.

I froze, my dick swinging between my legs. It was still 2 and a half feet long, my nuts having shrunk to a pair of manageable grapefruits resting warmly against my thighs.

Satisfied I wasn’t going to come any closer, Icarus returned his attention to his distended belly. It gave me a funny feeling, seeing that I’d filled this chiselled hero with so much cum I’d bloated him up. Until today it had never been something I’d ever thought about, now I’d done it twice. Expando’s belly hand been bigger, had looked squishier than Icarus’s almost roid gut of bulging abs. If Icarus hadn’t pushed my dick away, if he had drunk everything my massive nuts produced…how big would his belly have been? Then of course, there was the growth still yet to come.

“What’s going on? What happened?”

Density and Expando jogged into the room. Well… Density jogged, Expando had a sort of staggered gait. He was back to his normal size, the smell of cum rapidly filling the room. He gingerly adjusted himself, presumably after all that wanking his cock was undoubtably a bit sensitive. His eyes first went to my dick, tongue darting out for a fraction of a second before lifting his gaze to my face to give me his trademark smirk. Then he caught sight of Icarus and did a double take.

“No way!” he laughed incredulously. “You were giving Density and me all that shit and as soon as you get Super Dick alone you guzzle his cum yourself?! Hypocrite.”

“Shut up!” Icarus barked, jabbing a finger at me. “He did this to me!”

“What?!” I sputtered. “I don’t recall forcing my dick into your mouth! You seemed quite eager to do that yourself!”

Icarus made to take a step towards me and then at the last second changed his mind and instead stepped back. “He drank his own semen, made his penis almost fill the bathroom so that I had to come in to help. He then nudged the door closed with his dick, essentially trapping me in there.”

“And what, your mouth was open shouting ‘no, stop cumming’ and you accidentally swallowed some?” Expando quipped. His arm stretched across the room, his powers clearly back, to poke at Icarus’s cum gut. “You must have had your mouth opened a long time.”

“Fuck off!” Icarus smacked at Expando’s hand until the rubber hero retracted it. “When I was in there with him, my head got all… cloudy. I… I started… I started touching his cock and…and—”

Icarus let out a low moan, clutching his belly. I could almost hear it rumble, see his skin tremble as my cum began to take effect. Slowly his stomach began to recede, retreating back until his core was flat once more. As it contracted, his chest was already expanding, plumping up and pushing against his harness. His pecs swelled bigger and thicker, bulging against the harness to make the leather creak. His arms began to ripple and bulge, forearms twitching as he clenched and relaxed his hands.

“Ooooh…” Icarus stammered, chest rising and falling with his increasing breaths, going up with each breathe but never going down as much with the exhale. “Oh fuck…ahhhh oh shit.”

The front of his tights were rapidly filling, his crotch ballooning out faster than his thighs were thickening. The heads of muscle of his quads were rising out even more prominently than before, rapidly surpassing my waist in thickness. They were somewhat overshadowed, quiet literally, by his bulging crotch that swelled out, the basket sagging with the increasing weight. What was more impressive was the thickness of his shaft that was pressing clearly against the material. I could see the head of his dick, his shaft narrowing just at its base before bulging out again down towards his groin.

“Fucking hell,” Expando breathed. “That’s a fat dick you’ve got there, Icarus.”

Icarus hands quickly went down to try and cover himself. The motion made his pecs bulge out, spilling out even more against his constricting harness. His hands groped his inflating crotch bulge, pawing at the thick meat straining against his tights, failing to cover it as it just swelled thicker and thicker. His spreading lats pushed against his thickening arms, biceps blowing up and triceps expanding, all that muscle starting to battle against each other for space. His fumbling fingers were being pried apart, by his swelling junk and his muscles forcing him to move his arms out.

Unlike Expando’s super suit, it was clear Icarus’s wasn’t as stretchy as his rubber colleague. The seams of his tights began to spilt open, showing off the solid bronze flesh of his ripped quads. His heavy basket was drawing the waistline down, showing off the base of his shaft as it threatened to swell out. His movements were becoming more frantic as he huffed and moaned, trying to keep his tights together even as more splits and tears began opening all over. Calves rose like melons from the back of his legs, his quads surpassing his own waist in thickness and the middle of his fat dick spilling out while the head curved in, still covered. That is until the waist snapped and out it sprang.

“Whoa—!” said Density, Expando and I.

Icarus’s dick was a monster. It swelled out from the base of his groin, thickest at the middle before tapering down to the head again, it was so thick it’s weight forced it down, almost touching the floor already, his balls trapped beneath it pinned to his thighs that were pressed so tightly together he was in danger of pinching his sack if he wasn’t careful.

“Getting… too big,” Icarus wheezed, his harness cutting into his meaty chest. With a grunt one of the straps snapped, the separated ends cracking like whips as they were flung back by his swelling chest. What remained still dug into his shoulders, the sheer width of his arms would make it impossible to pull them off that way, trapped at the narrowest part of his underarm with no hope of movement. “Make it stop!”

Purely by coincidence his growth did taper to a stop, leaving Icarus flailing as a pumped up muscle blimp, with his torn harness and tattered tights. He wasn’t as big as Expando had been, he was able to waddle on his own power, spinning in a circle as he tried to look at the muscle expanse his body had become. His dick bobbing and swaying in the wake of his movements, the head just a few inches shy of the floor.

“That’s hot,” Expando purred, rubbing his crotch. “Fuck, I miss being that big.”

“Would you shut the fuck up!” Icarus bellowed, advancing on Expando like a moving wall of muscle, his dick leading the charge. It flopped and swayed, getting jostled by those shifting quads and the waddle of his gait. Expando just giggled, opening his arms and catching the monster cock as it pushed into him. “Get off!” Icarus growled, struggling and failing to reach Expando. His dick was just that bit longer than his arms, adding that to the fact his pecs limited the reach of his arms too meant that Icarus couldn’t get his hands on his stretchy tormentor. Expando had no difficulty get his hands all over Icarus’s dick though.

“Hey, I’m just helping you out,” Expando giggled, easily avoiding Icarus’s clumsy swipes at him. “You want to get back to normal don’t you? Gonna have to milk this python.”

“I can—nrgh—do it—rah—myself!” Icarus grumbled, grunting with every failed reach.

“You can’t even reach me mate, how you gonna pump this beast if you can’t even do that?” Expando lazily dodged Icarus’s next swipe then leant in and kissed the flaring cock head that filledhis hands.

Icarus’s movements faltered, “Fffuuuck” he moaned, muscles twitching and his cock throbbing.

“I know what I’m doing mate,” Expando cooed soothingly, moving his hand in teasing circles over Icarus’s sensitive head. “You two just gonna stand there with boners or you gonna help?”

Density sheepishly came forward, his purple speedos tenting with his erection. He tentatively watched Icarus for any objection before placing his hand on the thick shaft. “It’s such a thick beast,” he breathed, his hand barely able to cover a fraction of its girth. It was almost as thick as my cock had been at 5 feet, and this was only about 3. I can’t believe I was saying a dick was ‘only’ 3 feet, my sense of dick size had forever been altered now.

I felt a pang of jealousy as Expando and Density began rubbing and kissing Icarus’s bare beast, his pecs jumping as he panted and gasped in pleasure. The way his fingers were twitching and how his arms kept bending, it looked like he was trying to join in, to feel his own dick, but his massive bulk kept getting in the way. No, it wasn’t his dick he was trying to reach.

Silently, I approached the trio. They were all so wrapped up they didn’t pay me any mind. Expando and Density were kissing each other with Icarus’s huge cock head between them, Density rubbing against it with his chest while Expando’s arms were stretched to stroke the shaft and fondle those colossal nuts. Icarus’s massive arms were still flexing and bulging as he tried to reach for his nipples, which due to the sheer mass of his pecs were pointing almost straight down. His muscles kept him from performing the simple movement, so I thought I’d help him out.

As soon as I touched his pert nipple he let out a gasp of surprise and pleasure. Over his pec shelf I could see him watching me, his mouth twisting into a scowl, the words to tell me to go forming on his lips before the pleasure of my fondling chased them away. I leant in and took the nipple in my mouth, nuzzling his huge chest as I sucked and lightly nipped at it.

“Oooooh…ffffffuck,” Icarus stammered.

His biceps bulged against my shoulder, an indication I took that he wanted me to continue. I happily obliged, groping his heavy chest in my hands, squeezing and kneading at the meaty flesh. They were so dense and felt so heavy, but still squeezable until he flexed, in which they swelled and hardened. I rubbed my hip against the base of his shaft, trying to stretch over it to reach his other nipple too, squeezing and tugging on it with my fingers.

“Ugh… aaaah!”

Icarus’s body shook as his cock erupted, spraying cum over Density and Expando, the force of the first shot driving them back with a gasp and sputter. Density stayed back, wiping the cum from his face while Expando moved back in, his mouth stretching wide with his powers to catch as much as the firing cum as he could. I kept sucking and teasing Icarus’s nipples even as he began to shrink back down.

After a few seconds his cock stopped firing, twitching every now and then as the last shots of cum oozed out. Expando stayed attached to the slightly smaller dick, sucking on the last drop before releasing it with a wet pop. He straitened up, grinning with cum dripping from his chin and patting his swollen cum gut.

“Delicious!” he giggled, licking his lips. “Although I think I might have burnt my tongue, that shit was hot!”

Icarus, having shrunken down enough to regain some mobility, took a few waddling steps away from us. He pulled a few tattered remains of his tights off of himself and then looked over his body. He was still bigger than any conventional bodybuilder, and his monster of a dick was not going to be contained by underwear anytime soon, but he could at least move with less restrictions now. He admired his arms, felt his hefty chest, stroked the base of his dick which throbbed in response, the head weighted down to point at the floor resting over his beachball nuts.

“Your help was appreciated,” he said, a little breathlessly. “I think I can deal with the rest from here alone.”

“But I didn’t get—” Density started, “—I mean, we don’t mind helping.”

“Jealous, Density?” Expando teased, grabbing his gut and shaking it in the purple hero’s direction. “Don’t worry, you can watch me swell up nice and big again after this starts working.”

“Why are you so obsessed with looking like this?!” Icarus spluttered incredulously. He spread his arms, displaying his mass in a way I think was a counter argument to his cause. He was a godly specimen of muscle and strength. I think Density, Expando and my dicks all gave a little jump.

“Because it’s fucking hot, that’s why. Just all that power, all that strength filling your body up, so swollen and massive—”

“And practically immobile!”

“So what? If I really wanted to move I’d ask Super Dick to give me another blast and just grow where I want to go. Why walk when I could be everywhere!” Expando caressed his cum gut affectionately, his mischievous eyes aglow with excitement. “Gonna get so big.”

“Well,” I hedged, hating to burst his bubble even as hearing him voice his hunger for more size was making my cock throb all the more. “I erm… don’t think you’re going to grow from Icarus’s cum.”

Expando’s hand stilled on the crest of his gut. “Come again?”

“It’s just… you drank some of your cum, right?”

“I told you not too!” Icarus snapped, bearing down on the bloated blue hero. Expando did look a bit flustered at being called out but quickly recovered.

“It was only a teeeeeeeny tiny bit. Oh don’t look at me like that,” he scoffed at Density, “my suit was full of the stuff, still is, was hardly difficult to sneak some past you. Admittedly it was hard to tell if I grew at all but I thought it was just because I’d not had a lot.”

Density cleared his throat. “I guess if we’re being honest…I tried some too.”

“Of for fuck’s sake,” Icarus grumbled, going to put his face in his hand but having trouble when his biceps and pecs got in the way.

Expando however was sputtering with laughter. “Cheeky git, you should have just said and then we could have both guzzled and grown!”

“I wasn’t sure it would work,” Density said with a shrug of his shoulder. “I only had a bit too but nothing felt bigger.” He groped his crotch. “I was so hard at the thought of it though.”

“Well you can have a bigger hit straight from the tap when I start growing,” said Expando, slapping his gut like a drum. “It’s bound to happen right about…”

We waited. Expando watched his gut expectantly, waiting for it to recede and the rest of him to start growing. The seconds dragged on, turning into minutes and still nothing happened. After almost five minutes of just waiting, Expando’s eager grin was faltering.

“I think it’s just my cum that causes growth,” I said quietly. “I don’t think I can pass it on.”

“Shit,” Expando sighed, hefting his gut and making it wobble. “Are you sure?”

“While the evidence seems to speak for itself, perhaps I could take a look?”

The new voice was a deep rumble, a ring of amusement softening the words. We all looked to the doorway to find a tall figure in a skintight green super suit, a mask that covered his head concealing all but his eyes which twinkled with an otherworldly green glow. It was the last member of the Wardens. Watcher.

Under normal circumstances, Watcher was the biggest of the team. He stood at about 6’6” with an impressive body, wrapped tightly in his green suit, darker around his arms, edges of his core and his legs with a bright section over his chest and abs. Nestled between his pecs was a rhombus with an eye symbol at its centre, and as he walked into the room his cape billowed majestically behind him. His green eyes swept over us all; Density looking bashful, Expando with his distended cum gut, Icarus naked and still pumped up to impossible proportions, and me, also naked with my unimpressive body and oversized cock dangling between my legs. We must have been quite the sight.

“I hear the Body Builder has been experimenting,” said Watcher in that low voice of his. “It appears he wasn’t the only one.” He approached me, offering me his large hand. “You’re Steven, correct?”

I took the offered hand, watching as the big, black hand squeezed mine in a firm handshake. He then reached up and pressed something at the back of his head, causing his mask to… fold away, revealing a chiseled but kind looking face behind those powerful green eyes. “Since you already seem to have seen everyone’s face already it seems silly to keep mine on. I’d still rather you call me Watcher however.”

“Yeah, of course,” I said swallowing hard. He was just so tall, his eyes were… intense to say the least. I knew he had a lot of vision based powers, it certainly felt like he was taking in every molecule of my being.

“Very interesting,” he said, leaning back and then looking at the rest of his team. “I’ve not had a full briefing but from what I gather, Steve here has had a unique reaction to the Body Builder’s formula. Who wants to tell me how this—” He waved to the pumped up Icarus to the bloated Expando. “—happened?”

“Perhaps Density should fill you in,” said Icarus. “I’d very much like to… take care of things.”

“I going to need a bit more than that Icarus. What does that mean?”

“It means he wants to spank the monkey to get smaller again” said Expando, brash as ever.

Watcher didn’t react so he was clearly used to these sorts of outbursts. “I see. I take it Icarus was bigger before you kindly took on some of his burden?”

“He was hoping to get bigger again himself,” said Icarus. I noticed his cheeks were flush, probably from having his teammate tell everyone he was wanting to slip away for a wank. If he was attempting to try and drop Expando in it and make him feel guilty for getting caught out too, the blue ball gut showed no signs of remorse though.

“You should have seen me Watcher, I was immense! Bigger than sunshine easily. Although I will admit his dick might have been a liiiiiiitle bit thicker, but just look at that monster!”

“You’re unreal,” grumbled Icarus, twisting away in a futile attempt to hide his huge sausage.

“All that aside,” said Watcher with patience, “how did this happen? With no disrespect Steven, and I don’t blame you for this, why is he even here? He should have gone to Eugene labs for observation, not sauntering around our base naked and blowing my team up.”

I really wished I had something to cover up my dick. There wasn’t even any furniture in the room I could shuffle behind to even try at modesty. My discomfort paled however compared to Density who was almost dwindling under the combined scrutiny of the rest of his teammates. The colour was draining from his face as he raised his hand.

“That would have been my fault,” he said, voice low and heavy with guilt. “The Board has already wrapped my knuckles for it. I… I just thought that…” he huffed in frustration. “I don’t know what I was thinking, okay? I’d just seen his dick suddenly grow, he was on the floor looking helpless and hot with it all hanging out and… and I…”

“Ah hah!”

Icarus suddenly surged forward, his heavy footfalls echoing around the barren room and cock flopping around as it bounced off his powerful thighs. “You see, he does something to us!”

“We noticed, big guy,” said Expando, bumping Icarus’s cock with his gut.

Without looking, Icarus gave Expando a little shove, almost unbalancing him and sending him waddling and wobbling into Density. His attention was fixed solely on me with the intensity of the sun. “When I was in the bathroom alone with him I could feel myself being drawn to him. My head was all cloudy and all I could think about was what it would feel like to get his cock in my mouth, to taste it.” Despite the anger curling off his words like smoke, his dick twitched, chubbing up as though he was getting turned on at the memory of it. “He’s probably been working for the Body Builder and is using some of his mind control tech to… seduce us until we’re all immobile muscle blimps so he can take over the city!”

I wanted to laugh. I was sure Expando would make a joke at how ridiculous the whole idea sounded, but when Icarus’ accusation was met only with silence, my throat suddenly felt very dry.

“I’m not a spy,” I said, knowing it was a pathetic rebuke. Icarus snorted dismissively and the rest of the squad now had a glimmer of suspicion in their eyes. “Please, you have to believe me, I’m not a spy, and I’ve not done any of this on purpose!”

“It might be best if we detain him,” said Watcher slowly. “Just as a precaution until we know more. We’ll have to run a background check as well as a few tests on your… predicament.”

“No.”

Hope swelled my heart as Density stepped forward, coming between me and the rest of his squad. It would be an understatement to say that having his broad back before me, a barrier against the accusatory stares of these heroes, gave me great comfort. I immediately felt safer, knowing he was willing to protect me.

“I admit I made an error bringing him here, but it was my idea. He didn’t suggest it or manipulate the situation, I just…I just had a feeling that it would be safer for him here.”

“Mind control can be subtle,” said Watcher, his tone like iron. “I can see his physiology has been drastically altered, he could be producing pheromones that have influenced your decisions. It’s obvious you’re feeling very… protective towards him, and that could be a result of—”

“No, I’m protective of him because that’s what I do, what we are supposed to do!” He cast a look at me over his shoulder, his eyes still white behind his mask, the only one in the room still wearing one. “We protect those in need. He may have been changed, been given abilities he doesn’t understand, but that’s no reason to treat him with suspicion. I would have thought you of all people would understand that, Watcher.”

“Ooooh,” Expando cooed, before Icarus cuffed him and he went quiet with a pout.

Watcher didn’t pay them any attention; his intense green eyes were for Density alone. After what felt like an eternity, those broad green shoulders loosened and he seemed to relax. “Okay, he can stay. We’ll get a room set up for you, and then I’d like to take some semen samples from all of you. Now Steve, I ask that you refrain from blowing up my guys any more so keep your samples in containers.”

“I’d make a good container,” Expando pipped up, caressing his cum gut.


So I didn’t have to walk around their base naked, they gave me some clothes. They were too big for me but at least it gave my dick plenty of room. I was grateful for the extra space, even after my dick shrank down after filling a few containers for Watcher, it didn’t seem to take long for it to start growing again. It was so easy for me to get aroused, then again I was surrounded by all these muscular studs in spandex or less.

It also didn’t help with Icarus moaning away as he gave his sample next door, then come out in nothing but a robe. It was open to show off his pecs, which while not as huge as they had been, they had a sheen of sweat to them. He nodded to one of the lab techs, his cheeks flushing when the technician’s nose crinkled. Before I could even wonder why I caught a whiff of the hot musk of his cum escaping the room. Considering when he’d went in he’d had to turn sideways to get through the doorway, struggling to keep his thick dick down as well, he must have cummed quite a lot to lose all that mass.

When Icarus had stepped aside to let the technician in, he’d looked up and seen me watching him. His lips pursed together and eyes narrowed and I felt blame shoot from that glare like a laser. He clutched his robe tighter to himself and stalked off towards the showers.

Expando had been a lot more jovial. When he’d given his sample and shucked his cum cover suit, he bounced over to me. He was back to his lithe self, having lost his cum gut and in a robe of his own.

“Don’t ask,” he said, following my gaze to his now flat tummy. “Let’s just say I’ve been asked to fill myself with a lot more water than that and help put out a fire.”

It took a minute for me to get what he was talking about until I remembered the news story from a few years back. There had been a terrible fire at an abandoned tenement building, the fire brigade was struggling to get there so the heroes had stepped in. I remembered Expando had been this huge, blue ball, about the size of a bouncy castle, getting rolled into place by Density and Icarus. His arms and legs had been lost in his bloated torso, head only just peeping out of his squishy neck and chest. He’d then spat out the water with enough force to reach the top-storey windows. After that, a little cum gut would have been easy to remove.

“Have you given your sample yet?” he’d asked. “I can help if you want.”

He sidled up closer, hand going to my crotch to feel the already noticeable bulge that had started rising while I’d been thinking how big Expando had been. Imagining if I’d turned him into that same round ball, this time filled with my cum, and how much bigger he’d have grown after that. Expando’s expression was an irresistible mix of mischief and hunger.

Watcher had swooped down on us though and shooed Expando away. “Don’t encourage him,” he’d grumbled, although I wasn’t sure which of us he’d been talking to. He stood over me for a moment, eyes on my crotch. “Have you been keeping track of its growth rate?”

I’d stammered and blushed, feeling flustered that he was using his X-ray vision to check on my junk. Looking back though, I didn’t think he’d actually needed any super vision to see what I was packing at that point. “N-not really.”

“Well, it’s just considering you just master-bated not long ago, it seems to have grown considerably in a short time.”

“Yeah, maybe a bit.” I was suddenly very aware of the hot feel of my shaft against my thigh. I might have been imagining it but I could have sworn I felt it growing down my thigh slowly but surely.

“Hopefully some rest will help. I imagine it’s been quite a day for you. I’ve prepared a room for you, I’ll take you there. Now…I don’t want it to seem like a prison, but I ask that you not leave there. I’ll come get you in the morning. I’m also not letting the rest of the team know so as to…prevent any late night visits?”

So that was how I ended up, alone, in one of the slightly better furnished accommodation rooms, trying to get some sleep. My dick was refusing to settle, steadily getting bigger and filling my head with horny thoughts. An endless barrage of all the incredible things I’d see that day, Expando and Icarus growing, kissing Density, Watcher’s arse, Icarus’s heaving pecs, Expando and his cum gut and giant dick… fuck me.

Giving up, I rolled onto my back and threw the covers off. I looked down at my spread legs, knees in the air and the impossible tent in my borrowed briefs. My cock was throbbing, straining against the material, the base visible with the waist band stretched away from my stomach and even leaving a gap at the legs as well. I could see my balls bulging out either side, smushed up in the briefs as well. It looked hot as fuck, but the uncomfortable levels were outweighing the aesthetics.

Reaching down, I lifted my butt off the bed and tried to pull the briefs down. Despite the fact I was trying to free it, my dick was making it more difficult than it needed to be. Just as I was about to fold the stretched waistband over the head, a shadow moved in the doorway.

“Need a hand?”

I gave a squeak of shock that turned into a grunt when my cock sprang free and slapped me in the chest. I tried to get to my feet, but my briefs were still part way down my legs, so I ended up rolling off the bed. The floor met my back hard enough to wind me and my cock slapped me again to squeeze out what little air I had left.

“Shit, shit, sorry it’s me, it’s me!”

Dazed and choking for breath I was then blinded as the intruder flicked the light on and bathed the room in brightness. I managed to sit up and slump against the side of the bed, the figure coming up behind me, thudding on the floor as gentle hands rubbed my back and stroked my shoulders. I took desperate gulps of air, causing me to give a few body racking coughs from my haste.

“Easy now,” he soothed, holding me like he was keeping me together. I felt comfort in his arms, despite the fact that he’d scared me into this state. Once I had some air in my lungs and oxygen was getting to my brain, I knew who had come for a visit. No longer scared, I leant back, a little surprised to feel the soft touch of a bare chest behind me rather than the slick toughness of his super-suit.

“You could have knocked,” I said, although it came out more of a croak and I had to clear my throat afterwards.

I felt Density shrug his shoulders. “I didn’t know which room you were in. I’ve been phasing through walls searching for you.”

“Why?” I asked, very aware of my cock draped over my thigh starting to throb and come back to life now my body was no longer fighting for breath.

“Is it weird that I… don’t really know? Just that I… wanted to check up on you?”

“Must be my hypnotic powers at work.”

“If Watcher catches us then I might just use that as an excuse. Joking, that would only get you in trouble and this is all me.”

Density’s hand slid down my side, resting on my hip before dipping down between my legs. His breath tickled my neck as his fingers brushed the base of my shaft which throbbed at his touch, visibly getting a little bit bigger as well. “Think he might have had something to do with it,” I said dryly.

“Maybe. I just thought…I still owed you when you first got here, before the great Expando snuck past me and—” His teeth clacked as he stopped himself. “—anyway. I know this has caused you a lot of grief and I wanted to help you with it.”

“And maybe get a bit bigger as well?”

“My motives are completely chivalrous, I promise.”

“Chivalrous? Is that your ‘sword’ I feel at my back then?”

“No, I’m just pleased to see you.”

Sighing, I sat up, shuffling away so I could turn round and face Density properly. My words faltered when I saw him though. I’d already known he wasn’t in his super-suit, but I was startled to see him in nothing but a pair of tented pyjama trousers, his tight, toned torso completely on show, and his face for once completely unmasked. His eyes were beautiful. They were a brown so dark they were almost black, but they smouldered with this inner fire. His left eyebrow had also been shaved to break off a little triangle from the main brown. It was… cute. He waited, letting me take him all in, then he lifted his hand and offered it to me.

“You may know me as Density. But you can call my Jacob.”
