As Ben strode across the entrance lobby of the lab on his way to the canteen for lunch with Jack he couldn’t shake the feeling that something was different. He couldn’t put his finger on it exactly but his body felt different, heavier somehow, and he still couldn’t shake the feeling he’d had in the bathroom that everything around him seemed to be slightly out of scale. Again, Ben simply shrugged it off putting these nagging thoughts down as nothing more than the after effects of the stress of the morning’s very strange events. The day had started off badly and had managed, somehow, to get worse at every turn. Ben’s mind dwelled on the text message he’d received from Dan and the tall tale of his ‘so-called’ perversion that had been spun by Jace, though admittedly it was, regrettably, partly true with the humiliation of springing a boner at the sight of Jace’s bulging arms washed back over him. Trying to turn his mind back to work didn’t help much either, his slip up with the serum only an hour or so earlier still weighed on Ben’s mind which was swirling with all of the possible outcomes. Concern was his dominant emotion, thinking of all the negative side effects that could come with an early stage, experimental compound intended for livestock…but there was a small part of him that was a little bit too excited at the prospect of a super-serum coursing through his veins. His earlier conversation with Jack seemed a little more serious than it had only a few short hours ago.
Finally, Ben entered the canteen, scanning the sea of tables in search of Jack’s familiar face as he helped himself to some lunch. Just as he had earlier that day Jack popped up behind Ben unexpectedly, only this time he seemed to not recognise his lunch companion right away, bumping Ben’s arm accidentally.
“Sorry about that, mate…” Jack apologised absent-mindedly as he continued to peruse the various dishes on offer.
“Uhhh…hello! Earth to Jack…” replied Ben, surprised and amused in equal measure that his best friend of more than ten years seemingly hadn’t realised who he’d bumped into.
“Oh, have we met befo—” Jack started before the realisation of who he was talking to hit him.
“Haha uhhh yeah, I’d say we’ve met once or twice,” Ben joked back, confused as to why Jack was acting so strangely.
“Ben! What the fuck…what happ—…how did…what?” shouted Jack, his eyes wide with shock, attracting more than a few surprised and disapproving looks from those seated nearby.
“Do you mind? Why are you acting like a weirdo?” asked Ben, mightily confused at his best friend’s strange outburst.
“Uhhh…have you seen yourself lately? Like…maybe in the four hours since we last spoke?” replied Jack, his voice dripping with incredulity.
“What are you talking about?” countered Ben, looking himself up and down. “If you’re talking about my lab coat then it’s a long story.”
“I’m not talking about your fucking lab coat, you dweeb. I’m talking about your…your muscles and…height. You look ready to burst out of those clothes!” rambled Jack, pausing after each observation to ogle Ben’s body.
“Oh, yeah…I must’ve picked up an old shirt this morning in my rush to get out of the house. I noticed it earlier but it’s really not a big deal, I promise you I’ll dress more appropriately tomorrow…” joked Ben.
“Ben, I don’t think you’re understanding me. Those clothes fit you fine this morning…in fact, that’s your favourite shirt! You wear it all the time!” replied Jack, astounded by his friend’s apparent lack of awareness.
“Wait…you…you’re right, it is my favourite shirt. How…” Ben tailed off as he stared down at his torso, finally waking up to the reality of his situation.
“How indeed…you’ve got muscles now Ben. Not just that, you’ve grown all over…look at how tall you are,” prompted Jack, squaring himself up to his friend in order to confirm the new height difference.
“Holy shit…I’m just a few inches shorter than you now!” Ben marvelled as he took note of the narrowing height difference between himself and his formerly towering companion. Amazed that he’d not realised his increased height immediately, Ben took a little longer to look himself over this time, raising his arms and flexing his newly developed muscles. At some point over the course of the morning he’d gone from being a short, scrawny weakling to a six foot something beefcake. He was by no means ‘big’, certainly still not a match for Jace, but his usual painfully skinny arms had been replaced by firm round biceps, his boney chest now sported two nicely defined pecs and his abs were clearly defined through the tight fabric of his now ill-fitting shirt. Ben stared and ran his hands over his new body, akin to the lean and tight physique one would normally see on an elite swimmer.
Ben was snapped out of his reverie by the disgruntled mumblings of a group of lab workers who were standing nearby, realising that he and Jack had now been holding the line up for the last 5 minutes. Quickly apologising to the waiting diners and filling his tray with whatever was nearest Ben turned away from the counter and headed towards a table right in the back corner of the canteen with Jack, who was still lost for words, following close behind.
“Okay, you need to tell me what’s going on…right now,” said Jack seriously as they sat down at their table.
“I honestly don’t know what to tell you,” Ben began. “I didn’t even realise this had happened until you just pointed it out to me.”
“There must be something that’s happened this morning…you don’t just fucking shoot up in height and pack on pounds of muscle at random,” Jack scoffed as Ben began to tear through his sizable tray of food at a frightening pace.
“Well, I did have a minor incident in the bathroom just before heading down here but it’s not like I just sat there and started growing,” replied Ben, recounting the confusing and, admittedly, arousing events that had occurred less than an hour earlier.
“Wait…you felt ill, went to the bathroom and then you plastered the inside of a stall and saturated your lab coat with cum?” confirmed Jack, astonished at the tale he’d just heard. “You don’t think maybe you should have started with that?”
“Okay, okay…you’ve made your point. I get it, it’s weird but in the moment I couldn’t think straight and once it was over I didn’t think much of it. I feel fine now and I certainly didn’t realise I’d changed or…grown,” Ben replied, slightly exasperated, through mouthfuls of food.
“Well, whether you realised it or not, you have definitely grown…there must be something you remember, something that happened to cause this,” Jack persisted.
“Not really…it was a pretty standard morning up until I started feeling funny. Well, except from the death threat text from my step-dad but I don’t think that would cause me to start growing at random,” explained Ben, taking himself back over the morning’s events. “Unless…no, no I can’t be,” he ruminated.
“Well…what can’t be? What is it?” Jack insisted.
“Promise you won’t freak out?” Ben asked tentatively, putting his fork down for the first time since they’d sat down.
“Oh…I don’t like the sound of this,” said Jack as his face dropped.
“Well, you remember when I texted you about Dan? I was pretty shaken up thinking about how fucked up the whole situation was and I tried to follow your advice and focus on my work but…but my hands were shaking as I administered one of the new hormone treatments and I accidentally pricked myself with the needle,” rambled Ben, barely pausing to take a breath. Jack’s face darkened as he took in what Ben was saying. “I mean, it’s not like I injected myself as such. It was really just a pinprick and besides the serum hasn’t had any effect like this on any of the samples…so…it can’t be, surely it can’t have done this to me. Right?” Ben continued.
“Ben. Please, please tell me this is some kind of joke…” Jack replied, his voice barely audible.
“I’m not joking, Jack,” Ben replied solemnly, as he once again began to shovel food into his mouth.
“This is fucked up, you realise that? You accidentally injected yourself with an experimental super serum and an hour later you’re growing and cumming like a fire hose and now you’re eating like a…well, you’re eating a lot,” Jack pointed out.
Now that Jack mentioned it, Ben realised just how hungry he had been and just how messed up the morning’s events sounded when he heard them laid out. Thinking about the situation he found himself in, the growth, the insane jerk off session in the bathroom, his ravenous hunger…Ben couldn’t help but wonder how much further the serum could take him, if it was indeed the serum that had caused these unexpected changes. This is what he’d always wanted, this could be the chance to realise all of his wildest muscle filled dreams…so why did he feel so unnerved?
“Well, when you put it like that,” Ben replied, his mind again abuzz with possibilities, as he felt a familiar tug at the crotch of his pants. “Oh no, not again,” he sighed.
“What now?” asked Jack, rolling his eyes.
“I’m…I’m getting hard again,” answered Ben, his eyes gesturing down towards his crotch. Jack’s eyes widened as he realised what Ben was implying, glancing under the table his jaw dropped.
“Uhhh Ben…when I said you’d grown everywhere…well, it appears I really did mean everywhere,” said Jack, his voice tainted with shock and more than a little jealousy. Ben glanced down himself, taking in the sight of his now sizable, throbbing bulge.
“Oh shit…how big did it get?” Ben asked aloud, the sight of his impressive bulge only turning him on more.
“This is turning you on, isn’t it? Ben, just think about this before you do anything stupid,” warned Jack, evidently concerned about the possibilities Ben saw opening up infront of him. Jack, much like Ben, had always been attracted to muscle and growth but had never come close to Ben’s level of fascination and desire.
“Oh fuck, not now Jack. The last thing we need is for me to go full cum fountain in the middle of the canteen,” Ben moaned, a small spot pre-cum already leaking through his trousers. “There’s only one way to know for sure what’s happening to me…I’m gonna go run a blood test in the lab and find out once and for all. I’ll meet you out front in half an hour, we’ll have to take a day off until we’ve figured this thing out,” said Ben, desperately trying to take his mind off the monster throbbing in his trousers.
“Yeah, I think that might be a good idea…” agreed Jack, standing up to clear away the food trays.
“Oh…Jack, I might need to borrow your hoodie…better take the jacket as well,” apologised Ben.
“Fine, but I’ll want those back…and don’t get cum all over them like you did your lab coat! That jacket is expensive!” said Jack before letting out a long, resigned sigh. Ben hurriedly donned the hoodie, wearing the hood up in an attempt to disguise himself as much as possible, the last thing he needed now was for Mark or one of his other colleagues to recognise him and start asking questions. Standing up he quickly covered his crotch with Jack’s jacket and strode off out of the canteen towards the research lab avoiding making eye contact with anyone on his way out. Scurrying nervously up the stairs towards the lab, Ben was keenly aware of his unsubsiding erection and the rapidly growing patch of pre-cum currently seeping through his trousers. Seeing a supply cupboard up ahead Ben rushed along the corridor and entered in search of a lab coat or apron…anything to cover up the obscene sight of his engorged bulge. Seeing a rack of lab coats, Ben selected the largest size available hoping to cover himself up as much as possible as he continued on to the research lab. Buttoning the lab coat all the way up Ben’s bulge and pre stains were, thankfully, covered…for now.
Racing down the last stretch of corridor leading to the research lab he’d been working in that morning, Ben gave a small sigh of relief having made it there without being spotted. Scanning his key card the door swung open and Ben stepped through, the throbbing of his bulge becoming almost unbearable.
“Oh fuck, I can’t take this anymore…” he moaned, unzipping his trousers and letting his engorged member spring upwards making a satisfying thud as it hit his abs.
Jesus…how did I not notice the size of this thing in the bathroom earlier? It must be easily 10 inches and these balls…fuck they’re like lemons, Ben thought to himself as he scanned the room for an appropriate receptacle to release his load into. Spotting the water dispenser in the corner Ben had a wild idea, leaping forward and emptying the gallon water tank out over the sink he thrust the tip of his cock through the rim of the emptied vessel and finally unleashed the torrent of cum he’d been holding in his balls since leaving the canteen. The force behind his ropes of cum took Ben by surprise as he allowed himself to fall back against the door for support, unable to stifle his deep, guttural groans of satisfaction. Finally, after more than half filling the gallon water tank, Ben’s erection subsided. Completely drained and in a state of ecstasy Ben forced himself back into reality and stuffed his junk back into his trousers before carefully placing the cum filled tank on the floor so as not to spill any and leave any incriminating evidence. Still out of breath from the intensity of his orgasm Ben staggered over to the counter and pulled out a testing kit from the cupboard, filling the test tube with testing solution and placing it in the rack. Pulling out a fresh needle in order to draw some blood from his fingertip the irony was not lost on him that a pinprick to the finger may have been exactly how he ended up in this situation in the first place.
Steadying his hands, Ben gently pricked the end of his finger and allowed a few drops of blood to drip into the testing solution before disposing of the needle and retrieving the activating agent. Ben added 10 drops of the activating agent into the test tube before putting the stopper in and shaking to combine the solution. There, now we wait… he thought to himself as he stowed the test tube and a testing strip in his lab coat pocket. As he disposed of the test materials, his eyes landed on the drugs locker containing the serum samples…all it would take was one swipe of his key card and he could fulfil all of his wildest dreams. Feeling that pang of arousal once more Ben let his lust overrule his logic and opened the locker, reaching up he grabbed a handful of the capped, pre-prepared syringes and stuffed them into his other lab coat pocket. Whirling around and reaching for the door, Ben had just made it across the threshold when he remembered the tank filled with his cum sitting on the floor of the lab. Turning back to retrieve it he caught sight of Mark heading up the stairs at the bottom of the corridor. Determined not to be discovered now, Ben grabbed the cum filled container, wrapped it as best he could in Jack’s jacket to conceal its contents and raced towards the stairs at the opposite end of the corridor.
A few moments later, after dodging several members of the lab’s staff, Ben finally reached the car park and saw Jack waving to him from across the lot. Ben had never felt as much relief in his life as he did at that moment, he hurried over to his waiting friend and breathed a sigh of relief.
“Hurry up, I’ve got us a car!” yelled Jack.
“Wait…how did you find a car in the space of half an hour?” gasped an out of breath Ben as he reached Jack’s position.
“Called in a few favours, borrowed it from one of the tech guys…Is that yo—” Jack began.
“My cum? Yeah…I wasn’t gonna make it and I couldn’t very well leave this behind so I guess it’s coming with us,” explained Ben, unable to stop himself from chuckling at the absurd situation he’d found himself in. After a few moments, Jack began to chuckle too realising how insane the day’s events had been.
“This is fucking madness…get in before someone starts asking questions,” Jack managed in between his bursts of laughter. Ben headed to the rear passenger door and stowed his cum filled gallon jug in the back seat and strapped it in before jumping into the front passenger seat and doing his own seatbelt up.
“Why the fuck are you strapping your cum bucket in…it’s not a baby,” asked Jack, clearly amused.
“Of course it’s not, but we can’t leave it here and I don’t think your friend would appreciate you returning his car covered in my cum…would he now?” replied Ben matter-of-factly.
“Yeah, okay…I’ll give you that one,” conceded Jack as he climbed into the driver’s seat and turned the ignition. “My place?” he asked.
“Definitely your place,” agreed Ben, as Jack pulled away.
Relieved to finally be out of the lab, away from prying eyes, and on his way to Jack’s place Ben’s mind was racing as he replayed the day’s events in his head. Not only did he have to find a way to deal with the situation at home where he was pretty sure his step-father wanted to kill him, he also had to deal with the matter of his unexpected, though not entirely unwelcome, growth spurt. Yet another reminder of the bizarre situation he found himself in was the half gallon of cum he could hear sloshing around in the back seat. Strangely, Ben found the sound calming…almost like being at the beach and hearing the gentle waves crash onto the shore. As his mind drifted, letting go of his worries for a brief moment, he realised his hand had found its way into his lab coat pocket and was currently fidgeting with the test tube that would tell him whether or not he had exposed himself to the serum. Immediately, his mind began to whir again, mulling over all implications of his momentary lapse in concentration. What would be the long term effects? How was he going to explain this to Mark…hell, how was he going to explain this to his family? What if the lab called the police?
It was at that point Ben’s stomach sank as he remembered what was stowed away in his other lab coat pocket. Kicking himself for allowing his state of arousal back in the lab cloud his judgement so completely, Ben slowly shifted his hand down towards his pocket, tracing the outline of the pre-prepared needles he’d stolen from the drugs locker. One…two…three…four…five… Five full syringes of experimental serum now lay in his possession. Though he’d been concerned about how the lab would react to his situation before, the full realisation of what he’d done in stealing the serum samples slowly began to dawn on him. In the space of 30 seconds, with his brain scrambled by the intensity of his almost superhuman orgasm, Ben had managed to potentially throw his entire life away. Once the lab realised the samples were missing, they’d check the security system and see it was his key card that had last accessed the drugs locker…this key card evidence combined with his strange behaviour in the corridor when Mark had come across him doubled over, sweating and dizzy, would surely lead to Mark putting two and two together and realising what he’d done. That would be that…the police would be called, he’d be arrested and taken away in handcuffs, set for a life in prison. Unless…
Ben once again found his mind, and hand, drifting back to the five serum filled syringes in his lab coat pocket.
‘It would be so easy…’ Ben thought to himself, ‘Just one drop has blown me up to this size…imagine what just one full syringe would do’. As Ben allowed himself to indulge his muscle-fuelled fantasies for a moment, he found himself asking ‘Would I really want that life…to grow that much, become a freak of nature…nobody would ever mock me again, I could be unstopp-’.
“Uhhh…Ben, you’re not gonna…y’know, again are you?” asked Jack, looking over at Ben’s crotch nervously, cutting short Ben’s muscle-fuelled fantasising. Following Jack’s eyeline down to his crotch, the cause of Jack’s concern was clear. Once again, his newly enhanced member was throbbing in his pants. ‘Damn! Got a little carried away there I guess…’ thought Ben.
“Oh, sorry man…No, I think I can hold it, just please tell me we’re not far from your place,” replied Ben as calmly as he could, not wanting Jack to pick up on how turned on he was at the thought of more growth.
“Nah, we’re only a couple of minutes away,” replied Jack. “Surely you can’t be that horned up already…you shot a half-gallon load not an hour ago.”
“Man…you have no idea,” sighed Ben as he gazed out of the passenger side window.
A few minutes later Jack pulled up onto the drive of his house, unbuckling his belt and hopping out of the car. Making sure both the test tube and the syringes were still safely ensconced in his pockets, Ben followed his friend in jumping out of the car.
“Don’t forget your cum,” Jack jibed, gesturing towards the back seat of the car where Ben’s half-gallon of cum still sat.
“Yeah yeah, I got it,” retorted Ben, opening the rear door and grabbing the half-filled water tank. Shaking his head at the sheer absurdity of the situation Ben turned on his heel and followed Jack up the drive to the house. “Wait…are you sure no-one’s home? I don’t think your parents would appreciate me roaming around with a half-gallon of cum in one hand and a raging boner in the other…” Ben asked Jack, only half-jokingly.
“Yeah, no worries. They’re both away on a business trip for at least a week and Zach should still be at work,” replied Jack, assuring Ben that they wouldn’t be interrupted by Jack’s parents or, indeed, his big brother.
“Silver linings…eh?” Ben replied with a small chuckle. Stepping through the front door Jack turned and beckoned Ben to follow, heading through the hall and straight up the stairs. Ben was always impressed when he visited Jack’s house, unlike his own home Jack’s house was huge and immaculately kept. Both of Jack’s parents were successful business people and had amassed a small fortune through their myriad business dealings.
“I think the first thing we need to do is get you out of those clothes and deal with…that situation,” said Jack, pointing towards Ben’s engorged, leaking bulge.
“Uhh yeah, good idea,” nodded Ben.
“You can use my room and en-suite to get cleaned up, try to keep your cum off my carpet though…I’ll go and grab some of Zach’s old clothes for you, should fit better than what you’ve got on at the moment,” said Jack, nodding toward the door to his room.
“Yeah, thanks man,” said Ben as he headed towards Jack’s bedroom door, his need to release becoming increasingly urgent. Ben hurried through Jack’s room and made directly for the en-suite, not at all confident in his ability to not blow his load all over Jack’s expensive soft furnishings. After closing the en-suite door behind him and carefully draping his lab coat on the towel rail, Ben tore off his once loose fitting shirt and quickly undid his belt, dropping his trousers. To his surprise, and delight, rather than simply dropping to the floor, Ben found himself having to work his trousers down over his newly plump ass and thickened quads. Standing there, fully naked, in front of Jack’s full-length mirror Ben was able to take stock of his new physique properly for the first time. Gone was the stick thin, boney runt Jace had mocked so ruthlessly earlier that day and in his place was a tall, strong, toned physique. Ben explored his improved body with his hands, relishing the feeling of his well-defined pecs and abs, savouring the feeling of his powerful legs as he tensed his quads seeing the striations come to life.
“This is insane…I look like like a star fucking athlete,” Ben marveled aloud, bringing his arm up and flexing his newly formed biceps and triceps, watching on with excitement as a modest ball of muscle popped and seeing the horseshoe of his tri’s come to life with every flex. “Fuuuck….” Ben groaned in pleasure, unable to resist jerking his thick, veiny cock any longer. Almost instantly Ben was again overcome by the intensity of the sensation, feeling himself go weak at the knees, and staggered over to the walk-in shower, allowing himself to collapse to his knees. Grunting with pleasure Ben continued to pump his engorged cock, giving in fully to the almost primal urges he was feeling. One hand on his cock, the other continuing to grope and explore his firm, hard muscles as they flexed and tensed with exertion. Lost in his own world of lust and pleasure Ben didn’t hear Jack enter the bedroom and knock on the en-suite door.
“Ben? Ben, you good in there?” Jack called, hearing Ben’s groans and grunts through the bathroom door. “Alright, I’m coming in…” Jack warned, leaving a few seconds before turning the handle and entering the en-suite.
The sight that met Jack’s eyes was nothing short of obscene, he looked on in astonishment, unable to speak, as he watched his once scrawny best friend jerk off one of the biggest cocks he’d ever seen. Every single strand of every single muscle on Ben’s body was visible, flexing powerfully as his friend relentlessly beat his meat. “Ho-ly Fuck,” whispered Jack, barely able to muster his voice into action.
“Yes….fuck yes…more, come on…ohhhhh fuuuuuck!” Ben roared as he finally released his load. Jack had never seen anything like it. Ben’s cock was shooting rope after rope of thick, hot cum with so much force he was sure they would have easily knocked a grown man to the ground. The stream of cum just kept on coming, filling the walk in shower floor, the drains unable to meet the demand as Ben’s hand continued to rhythmically pump the load out of his cock. After several speechless minutes, Jack saw Ben’s orgasm begin to subside, the ropes of cum tailing off and Ben’s strokes slowing. By that point Ben, kneeling in a pool of his own hot seed, was completely spent, his body finally beginning to relax as his heavy breathing began to slow. The entire bathroom reeked of testosterone…the smell of Ben’s cum mixed with a distinct musk was an assault on Jack’s senses, the combination of the sight, sounds and smells he’d just witnessed giving Jack a raging erection of his own.
“Fuck…that was…” gasped Ben.
“That. Was. Amazing,” Jack finished, still in awe. “Look at you…look at my fucking bathroom!” he cried.
“Oh shit, how long have you been there! Look, I’m sorry man I couldn’t help it. I was so horny on the way over here and then seeing myself in the mirror…I just…I lost control,” confessed Ben. “It felt so fucking good.”
“Don’t you dare apologise,” Jack admonished. “That was the single hottest thing I’ve ever seen in my life, you’re a fucking beast now!”
“Ohhh god, don’t say shit like that…I’ve only just got this thing to go down!” pleaded Ben, gesturing to the only semi-soft 10 inch dick that was bobbing up and down in between Ben’s impressive thighs.
“Sorry man, I just had to say it,” replied Jack, as he retrieved several towels from the rail and handed them to Ben.
“Thanks,” said Ben gratefully as he rose to his feet, cum and sweat dripping off him, and took the towels from Jack and began to wipe himself down.
“I’d normally suggest you take a shower…but I don’t think that’s an option right now,” noted Jack, gesturing to the lake of thick cum that was slowly gurgling down the drain of the shower.
“Yeah haha…I guess not,” replied Ben, slightly embarrassed by the mess he’d made in his friend’s bathroom.
“Well, dry yourself off as best you can and then we need to talk about what this means,” said Jack as he retreated from the bathroom, turning to give the almost unbelievable scene one more glance.
A few minutes later Ben emerged from the en-suite, having dried himself off and splashed his face with some cold water, still nude and timidly covering his impressive softy up with his hands. “Ummm…you forgot to give me any clothes,” Ben pointed out.
“Over there,” Jack smirked, nodding to a small stack of clothes on the desk chair, as he watched his friend shyly scurry over and attempt to dress himself as quickly as possible. “If those don’t fit I’m cool with you…y’know, going commando if you get what I mean,” suggested Jack.
“Yeah, I figured you’d say that,” Ben chuckled. “I saw your…reaction to me in the bathroom,” he said, his eyes drifting down towards Jack’s still very visible hard-on.
“Oh…well, you can’t really blame me…can you? You have to admit it was a pretty hot view,” Jack replied confidently, though Ben could see his cheeks blushing slightly.
“Okay then, have it your way,” Ben said, dropping the t-shirt he was about to put on, clearly enjoying the confidence boost his new body, and Jack’s flirtations, had given him. He sauntered over to the bathroom as confidently as he could and fished the test tube and strip out of his lab coat pocket before walking over to join Jack on the bed.
“Is that the test?” asked Jack as Ben settled himself next to him on the bed.
“Yup, time to find out once and for all…” said Ben as he removed the stopper from the tube and dipped the test strip into solution.
“Well, now what…” asked Jack, staring intently at the test strip in Ben’s hand.
“It should only take a few moments,” he said as a faint line began to appear at the bottom of the strip. “Well, there we go…the serum is in my bloodstream. Now we just wait to see how much I was exposed to.” The two sat there patiently waiting for any further changes in the test strip…five minutes, ten minutes and fifteen minutes passed without so much as a hint of change.
“Soooo…is it done?” asked Jack quizzically.
“Yup…good news and bad news,” responded Ben. “The good news is I was only exposed to a trace amount of the serum…”
“And the bad news?” prompted Jack impatiently.
“The bad news is even such a small amount has added half a foot in height, tens of pounds of muscle, massively increased my sex-drive and given me a horse-cock that cums like a firehose,” replied Ben. “Oh and I’m probably going to be fired from the lab, possibly arrested and am probably going to produce an ocean of cum every two hours until the effects wear off…if they wear off,” Ben added.
“Ah…I see your point. Although I would have thought you of all people would have been excited about this…y’know, except for the going to prison part,” Jack responded encouragingly.
“I don’t know Jack, I’d say the whole ‘me going to prison’ part is a pretty integral factor here,” exclaimed Ben, although his friend did have a point. He’d be lying if he said he wasn’t enjoying the effects of the serum so far. What scared him the most was how enticing he found the idea of taking more, growing more…all his wildest dreams were within his grasp, if only he could bring himself to reach out and take them.
“Look, it may not come to that. I’m sure the lab won’t punish you…I mean, it was an accident after all,” said Jack. Ben’s stomach dropped, regret and guilt flashed across his face. “This was an accident…right?” asked Jack, picking up on Ben’s facial expression.
“Yes! Of course it was an accident but…but me taking five syringes of the serum from the drugs locker wasn’t,” Ben blurted out. Jack’s jaw dropped, his eyes widening as he processed what Ben had just said.
“Ben…when you say you took five syringes…you mean you stole them or do you mean…” Jack faltered.
“Oh my god, I mean I stole them! I didn’t shoot myself up with five syringes of an experimental hormone drug, I’m not insa—” Ben shot back.
“Oh, you’re not insane? You stole five syringes of an experimental drug! I’d say that’s pretty insane behaviour,” raged Jack as he got up from his place on the bed.
“Okay, okay I agree… but in my defence I wasn’t thinking straight. You’ve seen the effect the serum has on me when I’m horny!” Ben explained. “Of course I can see how insane it looks now but at the time my dick was doing the thinking…not my head,”
“Oh…this is just great,” sighed Jack, shaking his head as he paced back and forth.
“Look, I know it’s not a great situation to be in but there must be some way to fix this,” pleaded Ben. “Can you not change the records or erase the key card data or… or something… anything?”
Jack continued to pace for a few minutes more before responding.
“Alright, alright…here’s what we’re going to do. I’ll log in to the lab administrator’s account and amend the records to hide the 5 missing syringes, I’ll try and erase the key card entry on the drugs locker for good measure,” explained Jack. “Meanwhile you need to contact the lab and tell them about the accident…there’s no other way to explain this,” Jack instructed as he gestured up and down at Ben’s new larger frame.
“Do you think they’ll buy all of that? There’s no way they could figure out what we’ve done?” asked Ben.
“If I’m honest, I don’t know. I’d say there’s a good chance that it’ll work but there’s no guarantee that someone won’t dig something up…at this point we have no alternative,” replied Jack, his voice filled with resignation.
“Okay then… I guess that’s that,” said Ben, torn between doing the sensible thing and throwing it all away in pursuit of his ultimate fantasies.
“Agreed… now, there’s no time to waste. Every minute we spend discussing this the chances of someone at the lab noticing the missing syringes increases. You need to go and find some clothes that actually fit you, Zach will be home soon, I’ll go and tackle the bathroom before it stinks the whole place out and then I’ll deal with the lab,” Jack practically ordered Ben into action.
“Right…where am I gonna find clothes that will fit?” asked Ben as he looked over at the crumpled pile of Zach’s old clothing that still sat on the desk chair.
“Try my Dad’s room, second door on the left,” Jack said, pointing towards the hall before turning his back to Ben, grabbing the cum-filled water tank that still sat on his bedroom floor from earlier and heading into his cum coated en-suite with a heavy sigh.
Feeling bad for the mess, literally and metaphorically, that he’d landed his friend in Ben strode from the room in search of some wearable clothes, his bigger unrestrained cock slapping the inside of his thighs as he did so. Walking into what he assumed was Jack’s fathers’ bedroom Ben headed straight to the walk-in wardrobe and looked for the baggiest clothes he could find. Though he was more lean than large, for now, Ben still wanted to try and hide as much of his newly developed musculature as possible, his increased height alone would be hard enough to explain. After around 15 minutes of trying various items of clothing on Ben had finally found a top and bottoms that were wearable, though he wouldn’t be scoring any points for style. After tidying away the unused clothes Ben headed back along the hall, freshly dressed, towards Jack’s room.
“Jack?” he called, as he headed towards the en-suite. Receiving no response Ben assumed Jack simply couldn’t hear him, or that he wasn’t talking to him, and swung open the door revealing his best friend writhing on the floor, cock in hand…growing.
“Ugggghhhh…fuck…no, no, no,” groaned Jack. Ben knew all too well what his friend was going through…burning up, pain searing across his skin, his muscles seizing up. Looking at his friend’s growth, he found it hard to believe that he hadn’t noticed his own growth spurt only a few hours ago.
“Jack…you didn’t!” Ben yelled, lunging towards his lab coat, still draped over the rail, in search of the five stolen syringes. Much to his relief all five were there and remained intact, though that didn’t explain what was happening to Jack.
“I’m…I’m sorry…I couldn’t help it, it was just so…so overwhelming,” Jack managed to say in between his agonised groans of pleasure. “I had to taste it.”
Ben’s heart sank as he realised what had happened. The serum wasn’t only designed to increase size…it was also designed to increase virility. The increased volume of cum, the heightened sex drive, the larger genitalia…it all made sense now. An unintended consequence of the serum must have been to increase attraction to the subject by triggering a pheromonal response. The combination of Ben’s cum and sweat had driven Jack to need to taste his cum, not only that but Ben’s cum seemed to have similar properties to the serum itself. Were it not for the fact this was all taking place in Jack’s bathroom instead of in the lab Ben would be elated at this kind of breakthrough.
“It’s okay, just focus on cumming…it’s the only way to get it to stop!” Ben urged as he watched his friend’s body swell and stretch.
The already tall Jack was now positively huge, easily seven foot tall, his bony arms and legs thickening by the second, testing the seams of his clothing. Ben continued encouraging Jack to cum as his best friend’s pecs began to inflate at an alarming rate. Jack continued to stroke his lengthening cock with one hand as the other began to wander up his body, feeling the cobblestone abs and firm, defined pecs that had not been there only a few moments earlier. Watching this grotesque, but arousing, display of unabashed growth and self-worship, Ben felt his own manhood begin to stir once more.
‘Oh fuck…this can’t happen here! Not now!’ Ben thought as he grabbed the now emptied water tank and unzipped his freshly selected trousers, so as not to add even more cum to Jack’s already cum-fuelled growth spurt. As both Ben and Jack were gradually taken over by the effects of the serum, Jack continuing to swell and Ben once again in the throes of self-pleasure, the two men began to jerk themselves off in unison. Their animalistic grunts and groans echoed around the tiled en-suite as they both eventually began to cum. Enormous amounts of hot cum began streaming out of their two cocks, filling the bathroom and water tank all over again, before both of their orgasms subsided and left the two of them lost for words…
