Part 1: That Pumping Thought

Keith was your typical college athletic dream. Good grades, great looks, gets all the babes. Your typical young hunk. His blonde hair kept styled always to the left with a short hair cut and swept bangs. He could fill out a nice athletic uniform with his tight muscles screaming through the clothing as his uniforms and overstretched clothes sprawled across his muscular frame. At about 6’3” tall, he towered over most of the team mates. Didn’t matter what sport. Swim team, soccer, baseball, basketball, you name it. He was in it. The swim team was his favorite though. His time to show off what he had worked hard for since he was 18, now 23. His muscles glistened in the sunshine as his body would drip from the water cascading off his bulging shoulders. The sinews of his pecs and traps, biceps and large horseshoe triceps and ham like hamstrings and bulging thigh muscles, and his cobblestone 6 pack, creating a path for the streams of water to cut deeply on.

Every night, after a big meet, he would proudly display is confidence. At least, that’s how his family and his friends saw it. Except, deep down he was a little insecure. He had worked hard to build his 200-pound frame up to show that proportionate V taper that every man dreams of. The one thing, though, he hated the most was his package. Sure, he had the body any wet dream consisted of. But the one thing lacking, at least in his eyes, was the size of his cock. His balls were pretty above average already, so no problems there, about large hen egg size in a tight hairless sack.

His penis, however, was fairly average. About 5¼” when hard and about 1½” wide. Not porn star size by any matter but it mattered, a lot, to Keith.


Here I am again, standing in front of my mirror. Gosh, I really hate the way I have a smoking hot bod and nothin’ below the belt to match. Hmph.

“Keith! Dinner is ready!”

“Okay Mom! Heading down in a bit!” I hollered down to my mother. After these swim meets, why do I always have to look at myself and point out the worst thing about me? Why can’t I just be happy about what I got? What I built? I asked myself.

These thoughts keep racing through my head. Deep in the back of my mind, I kept wondering at the dinner table. What if I can build up my cock too, and why not my balls while I’m at it? Go big or Go Home, I always say. I chuckled to myself, thinking about the ridiculous idea.

“What’s on your mind, champ?” Dad asked.

“Oh, it’s nothing, just thinking about how I smoked the other swimmers in today’s meet.”

“You got that right! You’re just as much of an athlete as your old pop was in my heyday.”

“Don’t make it weird.” I shoved Dad’s shoulder.

“Pretty soon, Dad, Keith will be just as big as you!” my brother, Jason, chimed in.

Jason was about 6’ and is a bit athletic, but nothing like me. He did have broad shoulders and large feet. He’d be a real athlete if he could keep the muscle on him, but Jason didn’t built muscle easily. Though he maintained a fair bit of toned definition at 155 pounds. He’d have been good as a swimmer, but sports weren’t his thing.

“Yeah, sport. Try not to eat so much or you’ll outgrow the house!” Dad laughed.

“Anyone want desert?!” Mom asked as they continued their meals.

After supper, I went back to my room. That thought kept popping up in my mind. Could I build a better package? I lowered my sweatpants, revealing my blue boxer briefs with the slight mound I dreadfully called my own. Pulling them down, I went to my bedroom door and locked it so as no one comes in. I went my bed and brought my laptop. I looked up my favorite story website about male growth, specifically the muscles and cock section, to pound out my sorrows. I lusted to have the feeling of my cock skin to stretch over an engorging monster of a penis.

I my penis swelled to its full measly 5¼” size as I pounded away. I grabbed some tissues as I felt myself closer to climaxing. I usually have to use a towel, but I totally forgot about it. Tissues were the only option at this point. As pre started to flow like a faucet from my ample egg-sized balls, I began to twitch as I felt the fountain unleash within and I burst forth with my cum. It quickly overflowed the tissues and pooled on the tiled floor in my bedroom. I did the best I could to clean it up after I came down off of my high. My muscles were feeling pumped like after a workout. Well, it was a workout. The best kind, I would say. Hah. I chuckled, thinking to myself.

An ad popped up on the website and I noticed it after cleaning the spooge lake I created in my bedroom.

“Hm…” I saw what it said, thinking how interesting a fantasy it was, and hoe it was too good to be true.

Ad: The UberPump Pump Ring. Just slap on the ring around your cock and watch it grow! Looking to add serious size and girth. Not recommended for those with body image complex. $99 + shipping and handling.

“Well, what do I really have to lose, I suppose. I’ll try anything at this point,” I said, looking down at my little guy. It seems to be excited about what I was thinking. He certainly approved of this.

With my part time job at the pubic pool and the local gym, I had saved money through my freshman and sophomore college years. Now that I was a junior, it was time I started looking the part below the belt. A big package for a big guy. I whipped out my credit card from my wallet and clicked on the ad. I added the device to the cart and began reading. A secondary item popped up:

Ad: Do you want a more forceful pump while feeling a bit adventurous, then add on this UberPump Hand Pump to take it up a notch for the whole package. Recommended for those looking for SERIOUS GIRTH AND LENGTH GAINS.

“Sure, why the hell not,” I said and added this item to the cart as well. I looked through the typical legal jargon and entered my information. I finally purchased what I’d been looking at. The item says it had processed and will arrive Friday.

“Great!” I thought. “Just before summer break begins. Even more time to have fun!” And I drifted off to sleep.

Part 2: The Tightening (Inflation Begins)

Friday arrived and after waiting since Wednesday I sighed in relief. “Thank you!” I said to nobody. I’d thought I’d let myself get scammed in my post orgasm arousal brain. Once I got home from the local college, I rushed upstairs with the package to try it out for myself. No one home. All by myself. The perfect timing.

I opened the package and laid its contents on my bed. I went back to the door and locked it, as I was still paranoid about that, and began to undress down to my boxer briefs and walked over to the bed. I was staring down at a ring that supposed to be adjustable to “any size” the contents packaging says. I wondered how I am supposed to fit it over my small-ish and flaccid length.

“Better read this first.” I picked up the instructions. They were mostly in terribly translated English, so I decided to just download the SmartPhone app and pair it to the ringed device lolling around in my hand. It was slightly rubbery yet firm and seemed to have some give and cushioning on the inside diameter. I didn’t see any buttons or dials, just a rubber ring. My phone finished “syncing” the ring to the app. “Pump Me” was the name of the app.

“That’s a weird, cliched name for an app like this,” I said to myself.

The app quickly responded after opening. “Please place penis into ring and hold firmly in place,” the app prompted me.

“Well, better late than never.” I slid the ring on and held it firmly to my pubic bone. The app suddenly pinged and gave me my exact penis stats. “Wow, how’d it do that!?” I said out loud.

Suddenly I felt a tightening around the base of my cock. Snug, but not tourniquet tight. The app pinged again. “Fit complete. Begin inflation process? Yes or No?”

“Interesting. I don’t remember reading anything like this on the website,” I said as I hit yes.

I yelped as I suddenly felt the ring tighten further around the base of my dick and then a small prick.

“What the hell was that?” I said, panicking and wondering whether I was about to ruin my so called one-eyed pal.

The app pinged again. “What size do you wish to go?” it prompted with a text box. There was a small warning under the text box but I failed to read before typing.

“Um,” I say. I entered 9” long.

“Girth?” it asked next.

“Um… let’s get a little crazy seeing how this thing is probably bogus anyways.” I entered “8” girth.”

Ping! “Inflation Process beginning. Sit back and enjoy.”

I suddenly felt as if I was getting an erection. My penis felt flush and hot. It almost seemed as if it were literally inflating with air. I looked down at my penis as it quickly reached its 5¼” length. I felt a tightening in my groin as the ring began to force more growth into my cock. I stared at my penis wide eyed as it slowly began to pulsate and beat as if it has a heartbeat and began to inch slowly upward in length, surpassing its former length and going into new territory.

Length: 5.5 in

Width: 1.5 in

“Fuck! This feels freaking insane,” I yelled as I sat down on the end of my bed. Staring down, I took in my once-average cock growing and swelling, inflating with pure size.

I glanced down toward my phone as again and finally noticed the red warning under the text box input.

*Warning: Do not input size greater than 1 inch of current penis size. This may cause painful stretching of the skin. DO NOT OVER DO IT!

“Oh fucking shit! Fuck! Fuck! Fuck! Hell!” I burst out as I suddenly realized my horrific mistake.

Then suddenly there was a squeak and I felt my skin begin tightening around my shaft and head as the ring began to force more growth into my penis.

Length: 6.25in

Width: 2in

Squeak! The skin tightened even more as the growth continued its onslaught. My toes curled as an uncontrollable urge to cum took over. Then the skin tightened more and stretched. I stared down at my aching cock as it turned bright red and watched it inch a little longer. Another squeak, this time an audible stretching sound I heard coming from my over taxed skin. Veins stood out in bold relief as the pressure built in my cock.

I finally stood and wobble over to the dresser, digging through to find my tape measure.

I wanted to know exactly how long this thing was. Standing there, I place it over my tight, drumlike skin, and it reached to 7½ inches long. I had to measure the width. I wrapped it around and did some quick math: 2½ inches wide.

“Fuck!” I said, sweating a bit now as the stretch became more painful and oddly pleasurable. A sound that reminded me of overtaxed leather began to creak from my groin as another round of growth hit, this time with more force. Stretch… squeak. It was sounding more like a balloon.

“My God! Look at this fucking thing!” I looked down, still sweating from the onslaught my penis was enduring right now. It looked like a purple dirigible! And that it did. My penis had now reached an unnatural shade of purple. The sounds coming from my skin were still more like that of a balloon than stretching skin!

Another pump went and my penis inflated, faster than any other time before.

Squeak! Stretch! Squeal! This time my cock jumped a half inch in under 5 seconds.

Fuck!!!” I yelled. Realizing at this point I might actually make my penis explode for trying to be such a body image hog, I clawed at the device, trying to pry it off. Squeaaaaaaaaal! and a long stretching balloon sound came from my dirigible of a cock that’s attached to me. I felt it spread out to almost 2.75” in width, it having already reached its goal of 9 inches, albeit a bit longer than what I typed in. The girth was now spreading out to match what I had typed in!

“Fuck! It feels like I’m going to fucking pop!”“ I yelled out, clambering for my phone, trying to find anything to stop this onslaught.

*STREEEEETCH* *SQUEEEEAK* *BLOAT* *BLOAT*

The area just behind the head of the shaft began blowing up, giving it that fat baseball bat look. Stretch marks were beginning to appear along its length. My penis had me crying out in pain and pleasure as the final *PUMP* *BLOAT* pushed my cock into blimp-like territories.

With a final *BLOAT* and *PUMP* my bloated dirigible cock shuddered and stopped swelling, leaving me with a painfully erect cock that had been mutated into a dream and a horror as I looked on in silence, afraid to touch it. I felt the ring suddenly release itself. The pin-prick feeling was gone and now it just felt like a normal cock ring. A wave of lust filled me as thoughts raced through my mind.

“Holy fuck!” I huffed, as my trembling hand caressed the bloated cock balloon before me. Then the sudden realization hit me that the thing forcing my legs to stand wide apart, spread eagle, was my fucking cock. My dirigible cock was now a veiny monster pulsating within the vise-like grip of its skin. The cockhead, seemingly keeping in proportion to the penis, was now fist sized. The piss-slit now looked as if you could fit a whole quarter into it.

The stretched feeling was still there and still painful. I began to hunt for my phone. The app pinged.

“Final measurements:” it read out across the screen. “9.1in length. 3in diameter. Girth: 9in.”

I tossed my phone down on the bed and lay back gently, so as not to wobble the balloon stretching from my groin. As if not to pop it.

Feeling the tightness of its mass, I kept wondering why the app didn’t stop pumping my girth up when it passed the 8 inched I’d typed in.

This tightness was arousing. Almost too much. “If I cum I might pop!” I muttered. I ran my right hand up and down its fat length.

Fuck! I couldn’t even reach around this thing with my meaty paws. I tried to look up, only being met by my mighty pecs. Sweat was running down and into the cleavage of my muscle tits.

Stretch! “Fuck!” I felt my arousal heighten as my bloated cock engorged itself into a steel-like erection with all the stimulation it recently received. I rushed up from the bed, the dirigible bouncing into my abs, smearing pre all over them. I rush to my en-suite bathroom and caught a glimpse of the purple, stretch-marked mass that was my baseball bat shaped cock. I suddenly felt the urge to cum and was quickly overwhelmed by it. I rushed over to the toilet and before I got a chance to aim, I felt my balls draw up and tighten. I tried to release their contents into the toilet. The sudden extra pressure pushed my cock even further, bloating it more, as it normally did while cumming. The feeling and sound of my skin stretching more to accommodate the growing mass was intoxicating. The flow intensified and became like a fire hydrant release as my cum sprayed out as a stream. Not multiple squirts—a stream. The veins of my cock were standing out as my balls forcefully ejected their contents into the toilet.

Finally, my cock calmed down and began to deflate. The skin seemed like it sighed in relief as the pressure was released off of it. The stretched feeling was disappearing and turning more into heft—something I’d never felt before. My cock going completely soft now, the cock ring released fully and I was able to slide it off. It was a little more difficult now with the extra heft.

“Damn. I’m a fucking stud now,” I say, looking at the limp and thick beast hanging between my muscled thighs.

I walked back into the bedroom and got the tape measure out. “Let’s see how big you are soft now—hopefully you go down a bit more.”

Stretching it along the length. “Damn, I’m longer soft than I used to be hard.”

Flaccid: 5.5in

Flaccid width: 1.75in

“I guess I’m a grower.”

Picking up the phone, I begin reading the app’s support text. I read that some length gains and girth gains are permanent. “I guess we pushed the boundaries for you, little guy,” I said, rubbing him through my now bulging boxer briefs. It was still a bit sore from the punishment.

“I will say this, we are definitely going to be working you out more! I wonder if there’s a setting for balls to be pumped on here?” I mused as I combed through the app. Finding what I needed, a slightly devilish grin appeared on my face.

“We are definitely having more fun this summer with you!” I said, looking at the ring and the mysterious extra device I’d ordered with it with arousal and lust in my eyes. “Or find someone to experiment with….”

Part 3: The Gym Pump

I wake up in the morning with a raging hard on. My sheets tenting more than usual. The aching feeling of an intense erection plaguing my nether regions as I feel the stretch in my groin. The events of yesterday rushing back to me like a ton of bricks.

“Ah fuck!” I say out loud as I feeling the scratch of my sheets against the tight skin of my cock. Jutting up like a tent pole from my groin. Each movement sending a wave of pulsing pleasure to my balls. “It wasn’t a dream!” I huff, slightly straining as my cock twitches beneath the sheets.,

I reach forth and brush the side of the bulging tower jutting from my pelvis and feel the abrasiveness of the sheets against my skin. I shudder and feel pre begin to leak out like a faucet. Knowing what this means I toss the sheets off and I am met with a larger than usual erection than I am use to. Red and pulsing, with veins standing out. The largest of which, a large dorsal vein running down the middle along the top side of my cock.

I quickly again grab the tape measure sitting next to my bed on the dresser, stretching it from base to tip, I note that my erect length has decreased a bit from yesterday remember what the app said. “Some Length and Girth Gains are permanent.”

“Oh well.” I shrug. I measure the length: 7”.

I wrap it around the swell of my cock behind the head, still baseball bat shaped, and slightly marked by stretch marks still.

Girth: 6” around

“Damn.” I whistle to myself. “I guess I did lose some size since yesterday’s pump. We may have to fix that. Still, I am a shit load bigger than I used to be.” I rub the side of my girth, gently caressing the underside of the large expanse I now call my new cock.

“Damn,” I huff, “this thing is more sensitive than I remember.” I’m breathing heavily and beginning to sweat. “Better take this to the bathroom.” I rush to the bathroom and turn the shower head on full blast, letting the steam kiss my musclebound skin. My penis, if you can call it that now that it’s more like a toy to me, started jerking and twitching as the streams of water hit it. The twitching became more violent as I began thrusting my hips as if trying to fuck the water even from outside the stall. Suddenly, my balls drew up tighter than I have felt before, feeling as if I haven’t jacked off in months, and in no time I was spewing forth their contents with force. I streamed my cum across through the powerful water stream coming from the showerhead, hearing and seeing the stream splat against the tiled shower wall opposite of myself.

“Fuck.” I breathed heavily as I slide down onto the shower bench. “I should try out my new toy in the shower,” I said, wiping sweat from my brow as my large penis began its deflation process again, still aching from its sudden growth yesterday.

After carefully navigating my muscley sinew of my expansive pecs, large arms, hamstrings, and cobblestone abs, I gently scrubbed the soft tube, not wanting to go another round just yet.

I finished my shower and decided to put on my stretchy workout briefs, the ones that pushed everything forward, seeing how I now had something to show for it. I put on my workout gear, including a tight shirt and some workout shorts. Looking at myself in the bedroom mirror I saw the bulge I now had in my shorts. It was enough to make anyone wonder and I liked that. I felt my fleshy balloon chub up a bit, adding more girth to the prominent bulge. Still sitting at 5.5” soft, it packed a pair of briefs nicely now.

“Whoa there, buddy, don’t need you trying to tear your way outta this just yet.” I patted the mound softly as it twitched a bit. I wondered what it would feel like to wear that cock ring on my penis and balls and pushing everything forward a bit more. I pulled my shorts and briefs down and, after thinking a few seconds, grabbed the ring. Slipping the cock into the hole, I then decided to put one ball into the ring, then the other. With everything snugly in place I pulled up my shorts and headed downstairs. I downed a protein shake and a pre-workout to get my muscles fueled and pumped for a heavy workout today and headed out the door to the gym.

The place was called SuperPump Gym, with the name emblazoned across the front of the building. A place for true musclemen to work out. I strutted into the gym with more pep in my step than I usually did. I guess the added weight of my bait and tackle swinging in my workout briefs kind of got a guy going. Especially one that likes to show off what he’s got, like me.

I headed over to the treadmill after placing my belongings in the locker room and began my pre-workout warmup with some cardio. I felt my phone vibrate with a text message. Not really paying attention to it, I brushed it off as. If it were important they’d call. While doing my cardio on the treadmill, ten minutes in my phone vibrated again. I reached into my pocket and went to silence it completely. Just then I felt a sharp prick at the base of my cock. I winced, but seeing as these workouts always get me chubbed anyway, I chalked it up to the ring adjusting to the increased girth. And continue my workout. My phone vibrated again after my trying to silence it and I finally decided to shut the notifications off. Little did I know I’d made a big mistake.

Getting off the treadmill, sweaty and with my heart pounding into my meaty pec shelf, I felt the pounding in my groin as well.

“Mmmm… That’s odd,” I said, glancing down at my mound. It didn’t look that much different but I noticed how horny I had become while running. The chubby I had seemed to be normal for now so I chalked it up to the pre-workout I took earlier. I moved onto the weight sets. Deadlifts, Chest Flies, Lat Pulls… my muscles were engorging themselves until they felt like they were ready to burst through my skin.

There was something else, though. Something I had forgotten about until now while I was glancing in the mirror. I saw the mound I had with my chubbed up flesh balloon rising up like I was getting a full-blown erection. Noticing this I decided I needed to head to the locker room to “take care of business”. I reached down to my phone and noticed some notifications.

Fuck!” They were from the PumpMe app for the cock ring. And as I glanced down I felt the tightening of my briefs and shorts stretching to accommodate what was about to happen.

Part 4: Too Much to Handle

I rushed into the locker room and removed my briefs—luckily it seemed that the space was fairly empty except for a few muscle heads in the back corner. I gathered my senses as I felt a constriction force my cock to begin standing more up right in now-too-tight briefs that were previously only worn by someone with a less meager cock flesh.

I winced again as I felt the forced pump feeling I had felt yesterday during my ‘session’ and this time it felt more forceful. Something seemed off. I ran to the showers. Thank god these were separate stalls. I headed to the farthest one, since it had a larger room and a bench to sit on. I turned the showers on in almost all the surrounding stalls so no one heard the noises that were about emanate from my ballooning crotch.

I got into the stall and locked the door. I peeled my shorts down only to be greeted by not one mound but three individual mounds. It looked like I had stuffed in two goose eggs about 3 inches wide in my too tight briefs as well as a cock. I felt the force of the ring pump more size into my fleshy balloons as a creak can be heard from my over-taxed briefs. I remove them promptly before I ruin the only visage of clothing I have here.

Pulling them down, I am greeted by what can only be called a great furnace of heat radiating from my crotch as the ring forces more growth into my crotch area. The balloons were looking as if they were fighting for space in a leather sack. Then a *squeak* and a vise-like grip took hold of my cock as the growth accelerated the ballooning mass past 7.5 inches. Then *squeal* *bloat*. The flesh balloon stretched to 7.75”.

“Fuck me!” I huffed out as my penis inflated towards its previously tortured size. The stretch marks wqere reappearing as darker lines as the freshly healed skin was being taxed once again.

*Gurgle* *Glup* I felt my balls fill out the sack more, pulling them down with their weight as the ring somehow forced them to overflow with their own juices, backed up with nowhere to go but pool in their confines.

*Squeal* I felt the skin of my penis stretch once more as the area behind the head begins its glorious bloat into blimp like territories. *Glug* *Glug* My testicles, seemingly producing an endless supply of cum, were ready to burst forth.

Fucking Shit! What did I do!” I all but yell out into the noise of the shower hall, hopefully unheard.

I reach for my phone from the shelf. *Stretch* *Squeal* *Squeak* I felt the skin itself turn vise-like as it tightened around the fist-size head and the baseball bat of flesh heavily hanging from my groin. *Stretch* *Squeal* I opened the app as my penis now was seemingly reaching its previous scary size of 9”, only this time it seemed more intense and just generally more.

“What the fuck!” I cried out as my 9 inches stretched into 9.25” territory, elongating the balloon flesh even further, stretching the flesh to its bursting point! I wailed out a moan as the pleasure and pain were mixed in my brain. I glanced at the size settings on the app, not really thinking until I see the reason for additional swell and bloated blimp before me.

App: Size goal—10” length, Girth: 9.25”

“Fucking stop! I tried to get this thing pried loose from my loins to no avail as I gasped at the next sensation. My sack, now bloated with what appeared to be two avocados stuffed in a too tight fleshy sack, began to inflate more.

*Gurgle* Glug* *SQUEAK* as they jiggled and were forced to create more juices for the towering flesh jutting out before me.

*SQUEAALL* SQUEEEAK* I moaned loudly. *STREEEEETCH* as the now blimp flesh began to feel like it was now tearing itself apart and forced to grow more into a veiny monster. The veins were seemingly the only thing keep in the flesh balloon together as they, too, were forced to grow in size to feed the growth into this stretch-marked dirigible. The balloon between my legs was forcing them even while I was sitting down to spread-eagle more now as it approached its 9” girth, rounding out just behind the head.

The sound of overtaxed skin began to creak and groan from the flesh-balloon before me as I was forced to repeat the same mistake I had made yesterday. My penis was aching and groaning for it to stop. Or blow up. Its only choice now was to surrender to the onslaught of growth feeding it.

*SQUEAAAAAAAAAAAL* *SQUEEEEEEEAK* The sound of leathery tight skin filled the stall as a searing heat built up in my now baseball-sized testicles. The sack was stretched as tight like a drum. Veins appearing in bold relief on both shaft and ball sack as the skin becomes overly stretches. Stretch marks now appears all over my ballsack as the tight as a drum feeling turns more into and over inflated, have to evacuate my contents feeling.

Fuck! I feel like if this goes on forever, I may literally bust a nut!” I cried out to myself, holding one hand under my nuts, only to suddenly *GURGLE* *GLUP* and stretch out the sack to its bursting point, overflowing my meaty paw. My other hand was caressing the now overly inflated blimp jutting from pelvis.

*Stretch* *SQUEAK* *SQUEEEAL* My penis was now bloating up further, feeling the stretch practically screaming for relief as the sound of a balloon squeals through the air. Another burst of growth hit the groin as the whole package swells at once.

*STRETCH* *BLOAT* *SQUEAL* *GURGLE* *GLUP* BULGE. GROW!!!! GROW!!!! and grow it did. My penis felt one last long, squealing stretch before achieving its new inflated blimp like shape. The dirigible mass was seemingly floating through the air like one of our diving boards. Only this flesh was mine.

The balls ended their assault on my overtaxed sack before the stretch marks gave way, as if showing the stress of the skin being pushed past its limit. The fleshy orbs were now achingly backed up from the overproduction of cum they were forced to produce. They were aching to release their contents or explode from their overinflated softball size.

I sat on the bench, breathing heavily as every little movement caused my cock to stretch the skin more than needed. Looking down past my meaty pecs and cobblestone abs, there sat a massive fleshy tube, purple, pulsing with veins. The skin was stretched to the max, seeming the only thing being held together by the force of those veins feeding this monster sized bulging baseball bat of a cock. The dirigible-sized dong swayed with every movement, pulsing as if it were to breath. The slight small swell with every pulse to add a bit of size then relax as the blood gushes through the expanse of flesh. Each time, I feel the stretch of the skin pushed to the limit and then back off as the pulse recedes.

“Holy shit. I overdid it. Big time,” I huffed, looking down at my phone, slightly terrified to read the measurements now. This app seems to round everything a bit.

App: New Pump Size-10.2” long, Girth-9.25” around Diameter- still 3.1”

My hands shaking as I put down the phone. I nervously look at what I had created. A mass of flesh being kissed by the steam of the showers. The pulsing veins, the bulging orbs I now call my balls. My softball sized globes (I will call them that now seeing as “balls” don’t do them justice anymore) sat on the edge of the bench seemingly pulsating with their contents. A throbbing urge to release their steamy essence into the world flooded me.

I caressed the dirigible-like fleshy tube with my hand and used the other on my pulsating orbs. “These things must be holding a gallon of the stuff,” I thought, as I could physically feel them sloshing and still gurgling, ready to explode.

I gently worked my cock. The ring felt like it had released, but not the pin prick. “Odd,” I thought.

I worked my flesh balloon’s overly stretched skin, seemingly feeling like granite. As if the thing couldn’t get any larger, oh it definitely did. I was sweating at this point from my recent overexertion of dealing with my swelling balloon inflating from my crotch, and I felt the skin begin to tighten as I prepared for what appeared to be the largest orgasm anyone had experienced.

My fleshy orbs audibly gurgled and slosh as they were bounced about from my continuous two handed pounding on my fleshy tower. They seemingly and achingly swelled more with their contents and my hips thrust upward, as if my pole could now fuck a hole through the air. The feeling of power coming from me knowing I had the ability to grow a massive fleshy balloon from my cock and balls had me going more than usual. I forcefully humped through my fists and saw that pre was now shooting out of my cock as the globe-like orbs swelled beyond softball size. *GURGLE* *GULP* *WOOOOSH* I felt my legs lock out straight and my hips stop, hanging up off of the bench. I arched my back and a loud moan escaped my mouth. *STRETCH* *SQUEAL* My cock suddenly bloated up further as my cum forced its way down the shaft, seemingly inflating it more in the process! SPLAT! One shot! *SPLAT* Two shots, then my hips seized and nothing else. Then a rumbling feeling emenated from my balls as they drew up tight. A swelling sensation forced its way into the base of my cock as I saw the skin begin stretching further.

Oh.” I moaned louder now. “Fuck!” I felt the skin stretch as far as it could as the dirigible mass assaulted the skin one last time before unleashing its wrath on the stall.

“UHHHHHHNNNNNNN” I moaned as a continuously blasting stream fired out of my piss slit like a firehose attached to a hydrant. In fact, my cock resembled one—a veiny, red monster of cock flesh spewing forth its contents everywhere. After about a minute of a continuous stream of pressurized cum, my aching mound of flesh began to calm down. The deflation process began as my balls returned to larger than their normal size, larger than large hen eggs but not quite goose egg yet. The feeling of stretched skin was relieved and replaced by a satisfying weight. I’d brought my tape measure with me, so I quickly rummaged through the bag. My cockflesh was thick and heavy, laying across my upper thigh, my balls hanging over the edge of the seat.

“Fuck.” Soft (I am not shitting) post inflation: 7” long and about 2” wide.

“Damn. How are you gonna fit into my briefs now?” I thought, rubbing the sore girth of my soft fleshy tube I now called my cock. “I have got to be more careful with this thing if I don’t want to outgrow my clothing. I already need to shop for new underwear. Fuck!” I suddenly face palmed, realizing that I needed to be able to fit into speedos for those swim meets.

“What will the guys at practice think?” I thought, continuously massaging the sore mass between my thighs. A faint aching feeling could still be felt in my balls, and there was a gurgle as I got dressed and cleaned up.

I look back at the one-inch deep layer of spooge I was leaving for the facility to clean up. *Gurgle* That feeling still rumbled deep in my balls as I remembered I was still wearing the ring.

I had to get home fast before things get messy again. I rushed out the door, just as I felt my briefs begin to tighten around my balls as they produced their seed at a terrifying rate.

“I need to get home fast!” I rushed home, ran upstairs, and slammed the door. Undressing and eyeballing the fleshy orbs I could see they were beginning to inflate with more cum, stretching the sack out more.

“Here we go again…” I moaned as I headed to the bathroom, locking my bedroom door and moaning from the inflation that was about to begin.

*ding* *dong*

I totally forgot about Michael coming over.

“Aww shit,” I yelled. “Why did I have to go and overdo it on a day Michael is coming over?” With that I headed downstairs in nothing but boxer briefs, seeing no one was home. I opened the front door and there stood a tall, muscled, and deeply tanned hunk. Michael, my best friend.

Part 5: Exceeding My Limits

Here I was standing in the doorway in nothing but my boxer briefs, which were straining from the balloons between my legs I called my balls, which were pulsing and swelling with more copious amounts of jizz than I could keep up with. Each bump and movement from my thick thighs had them jiggling in their tight sack. Waves of pleasure engulfed my groin with each step. I opened the door to realize I was now standing in the foyer with nothing but my bulging boxers with my meat protruding itself into my best friend’s face.

“Hey bud,” he said, then looked down. “Holy shit!” he gasped. “I’d asked how it’s hangin’, but it looks like I can see how far. Putting on a nice display there for the world I assume.” I shoved him into the house quickly shut and locked the door. He moved quickly inside while chuckling.

“Hey, sorry about that. I forgot you were coming over,” I said. “About the bulge in your face, I was just fixing to take a shower after a hard workout. You know those get me worked up something awful. Want anything to drink?” I asked.

“Sure, got any…” He stopped. *Creak* *Glug* *Glug*

The sound permeated the air as we both headed into the kitchen.

“What was that?” he asked.

I’m facing away from him having one hand resting on the mounds in front of my underwear, stretching tighter as my now goose egg sized globes expand with seed, all the while still kicking myself for putting that damn ring on this morning.

“Oh it’s just our pipes in the house,” I lied, not really up for telling him the full story. “They back up sometimes with a bit of pressure when the showers are running.” Oh the irony… I thought to myself as another swell hit.

“Ah… Makes sense I guess.” Michael heard it again. I felt it again. My fingers were spreading apart as the mass expanded. *Glug* *Glug* *Creak*

We both heard it again, and this time I felt it build up as pre tried to escape the still-swollen tube of flesh balled up in my too-tight briefs, the sensation of them swelling further past goose egg and now approaching small ostrich-egg size. I felt the cum boiling for release as the pent up fluid built, forcing the globes that were tortured earlier to ache and cry out ‘no more, too full’. I moved my hand to above my groin as if to hold my stomach, feeling the pulling sensation of my now two-pounds-each balls. I felt the pull deep in my abdomen as it strained to hold the weight while standing.

“You all right?” he asked me as he noticed I’d become a bit uncomfortable, and seeing me holding my lower stomach.

“Yeah. I’m all right. Just the pre-workout and protein shake I had earlier is giving me a bit of trouble.” I reached into the refrigerator, trying my best now to hold the bulging mass out of his sight. Now my balls were nearly twice their size since he arrived.

I find the drink he was asking for before my man parts decided to interrupt us any further with their swelling. I hand him the Coke, not realizing he was now standing next to me, looking down. I froze.

“Oh, thank you!” he said looking up, then back down… at his phone. Whewww… I sighed in relief, thinking he’d seen the balloons now causing the fabric to be practically see through at this point of the swell.

“Where’s your parents and brother?” Michael asked, still staring down at his phone, leaning his tight muscular body against the island in the kitchen.

“I think they said something about taking James out to go hunting for Apartments around the College. He doesn’t really want to be a dorm rat or stuck at home. Personally, I’d rather stay here… at least until I graduate.”

“Well, I think you’ll be a total chick magnate if you lived on your own to be honest. Every girl at the college looks your way!” he sneered, looking up from his phone smiling that goofy smile. *Creak* *Bloat* *Gurgle* then, a stretching sound as I felt my briefs near their bursting point.

“I… I b… better get back ups… stairs to my shower before the water gets cold.” I said, clutching a hand down to the bulging masses, holding them from underneath. My cock had joined the action a bit, stretching the fabric more as it inflated to its dirigible size. I brushed past him, slightly grazing his left thigh with my bulging groin balloon. I still wasn’t used to the size, or the inflation as they continued to seize up and then relax, as if trying to expel their contents and failing.

Michael turned around after feeling what seemed like a warm and slightly moist pillow brush his exposed thigh under the tight shorts he was wearing. He turned to see me hurrying around the corner and up the stairs. All the while my package was jiggling and bouncing up and down, pulling my now too tight briefs down, exposing the base of the ballooning erection coming on. I could feel the heat building into a furnace once more, sweating as I climbed the stairs, not knowing Michael was behind me at the bottom, staring up gobsmacked at what he could perceive to be a balloon bouncing up and down at my crotch through my now awkwardly wide gait thanks to my expanding crotch.

“I’ve seen him naked in the locker room. There’s no fucking way he’s that big?” Michael said softly to no one as he felt himself being drawn up the steps behind me, following me to my room.

I shut the door behind me, not latching it in my haste to pull off my now-ruined briefs, yanking them down and seeing the stretched-out pouch that looked as if it were made for a bull. I rushed to my bathroom where I quickly turned on the water to full blast so Michael couldn’t hear the groaning coming from my crotch as the skin was forced to spread against the now inflating ballooning mass of balls resting on my thighs. I felt them pulsing, sending shivers down my spine as the sensation builds to an intense fire. The searing heat was building up as I stroked my ballooning cock to full, tortured attention. An aching pulse could still be felt in the not-quite-normal size tower jutting from my groin.

I realized I’d left my tape measure in my room, then remembered the app on my phone. I pulled it up, seeing as I was still wearing the ring. The app read: 9” long 2.75” wide. Still a bit bigger than a normal cock. Definitely bigger. And pulsing with the urge to grow more. I quickly shoved that thought aside, not wanting to push my limits further as I was sure I’d exceeded them at the gym today.

“Fuck, uhnnnnnnnn…” I moaned out, hoping Michael was not hearing my tortured pleasure-filled groans coming from deep within me. I felt my balls pull up tight as I moved from a standing position and onto the shower bench, the hot steam kissing every tight muscley sinew of my body, every vein and skin of my crotch balloon. The masses quivering as my balls seize up to release their contents, I felt one drop shoot out. *Splat* then *dribble* and then nothing else.

“Is that fucking it?!” I looked on horrified at my predicament. Suddenly I felt my balls seize up against the underside of my ballooning pool noodle of a cock, and then fall back down in their overstretched sack. *Creak* *Gurgle* *Bloat*

No!” I cried out realizing that the sensation of drawing up then falling down was just my ballooning balls filling up whatever space was left in my drum tight sack. Now sounds of creaking skin could be heard as my arousal has sent them into overdrive.

“Keith. Are you okay there, bud?” Michael creaked the door open to the bedroom, hearing moans coming from the bathroom he worried for his friend. Then, *Creak* *Gurgle* *Stretch* *Squeal* then a “Unnnnnnnnnnhhhh Fuck!” coming from the bathroom as he silently moved to the sounds coming from the bathroom. He peeked into the doorway and through the steam-filled room. What he saw made him fall back and stumble onto the floor.

“Holy fuck!” he huffed out. “That… that can’t be all him.”

“Unhhhhhhh….” I moaned once more as I touched my balls, now jiggling as if being filled with water, the pressure in them becoming almost too much. Too much to handle. Too much for my balls to handle as what appeared to be waves of growth were surging them to greater size, exceeding what I though was possible my balloon factories to handle. Now reaching their previous softball sizes, weighing around 5 pounds each, my balls had exceeded anything remotely human as they jiggled like two overfull water balloons in a fleshy tight sack, straining against their own weight so as not to burst from each impact I am giving them with a fist.

“Why won’t you fucking release!?” I screamed, now trying to pry the device still trapped around my cock, feeling the bloat fill the ballooning masses now past softball size and into coconut territories as the sperm built and pressurized my cum factories below. Each blow I desperately sent into my balls caused a shock-wave to spread out among the mass, only for them to react and swell more, increasing my arousal and the desperate need to release before they exploded from the pressure.

*GURGLE* GURGLE* GLUP* BLOAT* BULGE* I felt the skin stretching more to accommodate the sperm balloons spreading my legs further apart. I rubbed my growing cum balloons, caressing them as my lust took over, edging them more to grow. And they responded in kind, now approaching large coconut sizes, each feeling like a 20-pound weight pulling at my groin while slowing gurgling and boiling their contents to put pressure on the inside of my balls. The balloons were now screaming out as the ache gnawed at me from within.

“Hey! Keith! Snap out of it!” Michael yells at me, pulling me back to reality as I felt the weight of my balls resting and nearly overflowing my lap, now extra-large coconut size and inflating bigger still. *Gurgle* Glup* Bloat* *Creak*

I heard the overtaxed skin and the overtaxed testicles creak as they were forced to bloat up further with their seed, a small river now gushing from my now over-excited cock.

“Michael. You gotta help me!” I pleaded to him, tears of pleasure running down my face, as I felt the next swell pumping my over inflating cum balloons further, the pleasure and feeling of what can only be described as pure growth. “No matter how much I try, I can’t cum! I need help!!!” I screamed out to him.

“Well, what do you want me to do about it!?” he shot back, nervous and panicky. Sweat was now running down my best friend’s forehead. I knew he was secretly into this stuff, he read the same website stories that I did. Only, now I have become one of those inflating crotch balloons in real life.

*Creak* *Gurgle* *Squeal* The massive overly inflated organs, swell into bowling balls. The spray of pre cum intensifying as the pressure of my overfull balls begins to ache even more for release before becoming a sperm bomb.

Hurry!” I yell to him!

“ALrIGhT.” His voice cracked nervously. He took a second to think. “I should get undressed, in case things get a little messy.”

“Okay. Do what you have to do. Wait!” I stopped him. “Go lock the bedroom door. I don’t want anyone coming in on me like this, especially my brother.” Michael left the bathroom. “And grab the tape measure!” I yelled after him.

Michael returned to my bathroom as a stretching and gurgling sound could be heard emanating from the crotch balloons. Each was now as big or bigger than the heaviest of bowling balls—no longer able to expand, only fill with their contents. The pressure was increasing by the second, the orbs having reached their limit of expansion for now.

“For fuck’s sake, get your ass over here now!” I yelled over to him as I gently kneaded my balls, as if to coax out more sperm than they were producing. The cock ring was still attached to my groin.

Michael was in the doorway now, staring. “Holy fuck! I’ve seen you naked before and you weren’t nearly this big hard. Or at the swim meet. You barely had anything,” he said, mesmerized. He knelt and rubbed the side of my pulsing balls. Feeling his hands run over my tight sack, I groaned. He pushed in.

“This shit is packed in there tight!” At his poke I felt the achiness of the expansion increase, now overfilling of my tight sperm balloons. I felt them packing in tighter and tighter as pressure pains begin wracking my balls and groin. I was feeling it deep in my abdomen as the sperm factories gush out more pre, now streaming out of my cock tower.

“Stop playing around! It feels like they’re gonna burst!” I huffed at him, his indent quickly rebounding as the factories of sperm packed in even more pressurized cum. The pulsing was getting near unbearable as they continue to fill and overfill over and over again, near bursting. Sweating profusely now I caught a whiff of my man scent, and heard the rumbling of my bowling ball size balloons spreading my legs further as they attempted to swell, but to no avail.

“That fucker is huge!” Michael exclaimed, seemingly shifting his amazement from my balls to my cock. His thick callused hands gave extra stimulation on top of my own, now sending my balls into overdrive.

Awww fuck…. unnnnnnnnh. Keeeeep going….” I moaned out as my own practiced hands reached out to the thick veiny monster.

“How the fuck did you do this?” he asked, naked and sweating from the exertion. I was realizing now that four hands were better than two handling my pulsating balloon cock.

“I’ll have to show you….. nnnnn ha…. later,” I puffed out. “Unnnnnnhhhhhhh—” I felt a kick in my balls as the pressure neared its bursting point. The bowling ball sized cum balloons seemingly swelled a final time, a constant *stretch* sound coming from them as they prepared to explode their contents everywhere.

Damn! They’re gonna blow!” Michael said as he began to back away into the corner of the shower. I felt the pressure increasing drastically in my balls as they continue expanding further. The cum was now shooting out like a fire hose from my cock. The veins stood out as they approach volleyball sized. The balloons shuddered, then—

Awwww fuck! Unhhhnnnnnnnnnnnnn!” I yelled, as the final bloat of the cum balloons halted. *BLAST* as a continuous stream of hot cum roared out of my cock balloon, spraying its contents everywhere. *SplaT* *SPLAT* as the sprays of cum went everywhere in the shower. The drain was now backing up from the heavy spooge lake being produced by my cumming water balloon balls jiggling and deflating now. The pressurized contents nearly drowned my friend Michael as a stream hits him, then completely covers him.

My stream finally settled down from my cum factories as my veiny monster, still aching from earlier today, began to deflate and go flaccid, though even sot it was still 7” long and pulsing with new life. The ring finally released itself. Pulling the thing off my now overly enlarged package, the kind any porn star would dream of, I threw it outside the shower stall and into the sink.

“Finally!” I moaned in satisfaction as the pressure feeling was no longer there. My balls were now sitting at about 4 inches wide now from their repeated torture from the device, stretching my now low hanging sack.

“Look at this mess,” I said, gazing at the cum soaked shower. “Michael—” I looked over at him, dripping with cum.

“Fuck!” Michael said, wiping cum from his face and laughing. “We need to do that again. This time I want it!” he said, as his thick 10 incher was sitting upright, quivering with anticipation.

Part 6: A Real Life Balloon

“Damn!” Michael gasped. His bulging, veiny 10 incher was sticking out with a slight bend down. He was clearly very turned on by the cum explosion my sperm balloons just burst forth.

He waddled over to the sink, his cock bobbing up and down and side to side with each step. His low hangers could be easily seen swinging halfway down his thighs. I saw him pick up the UberPump cock ring, rolling it around in his hands. “This thing did all of…” He motioned to my protruding balloons now laying heavily in my groin, the organs sighing as a relief was finally achieved.

“Yes. It did,” I said, wincing as I propped myself back upright on the bench, having slid down from the weight of my previously volleyball cum balloons. Each movement still sent waves of pleasure and pain from the soreness of the over expansion of my delicate man parts, now easily some of the biggest of anyone we knew.

“Dude. I have to try this thing out!” He quickly tried to place the ring around his cock.

“Wait a minute!” I gestured for him to wait.

“Hmph.”

I staggered to my feet, still reeling from the growth, dizzy and feeling exhausted. “You just saw that thing practically turn me into a cum balloon. My balls nearly exploded. And don’t even get me started on the gym….” I told him rubbing the back of my head, while still massaging just above my package feeling the soreness and weight of my newly grown balls pulling the muscles downward.

“Yea.. and it was fucking hot!” He seemed overly excited. His cock was still twitching in anticipation.

“You don’t know what you’re getting into. It’s not a toy, this thing is torture….” I tried to tell him, while attempting to lie to myself. I was feeling that nagging sensation of having my cock blimp out more and longing to feel that overfull feeling once again. I shrugged it off and swiped the ring out of his hand. “That’s enough. Now are you gonna take care of that thing or what? I don’t like it staring at me.” I point out to the quivering mass jutting from his groin.

“Oh. Sorry dude! This whole thing has me worked up,” he said to me, turning to aim at the toilet, stroking his thick tool.

“Geez! Why don’t you wait until I leave!” I shoved his shoulder as I place the ring into the bathroom drawer under the sink and left the bathroom. Big mistake.

Michael, seemingly lost in his pleasure-addled brain, eyed the drawer where I stuck the ring. Finishing his business, he swiped the ring and placed it firmly around his thick 6 inch flaccid cock and thick, round balls.

Coming back into the bedroom and seeing me struggle to find a sign of underwear that might fit, he asked about the ring.

“So, what is that thing called anyways?”

“It called the Uber Pump or something like that. Even comes with an app.”

“That’s an arousing name…” I saw him rubbing his bulge through his briefs, still not wearing all his clothing, the only thing that wasn’t ruined in the cum bath.

“Yea, and the app it comes with? Get this, its name is PumpMe.” I chuckled.

“You’re telling me. It sure did pump you up there, bull nuts.” He’s laughing hysterically.

“Shut up dude…” I glared at him from my drawer. Still naked, trying to find something to fit my overgrown package. “It really felt like I was gonna… you know?”

“Explode…” we both said at the same time.

“Yeah I know,” Michael said, with a glazed look in his eye as he was searching on his phone, putting it back down after a bit. “Your balls were really bobbing about in there. The fucking felt tight as a drum. I could feel the cum sloshing in those bad boys. What I wouldn’t give to be in your shoes then…” His eyes glazed over again.

“Hello! Earth to Michael.” I snapped my fingers at him. Finally resorting to wearing my swim briefs, the only thing stretchy enough to accommodate the recent grapefruit sized bulge I now had at my disposal, which was jostling around as I stepped forward, bouncing off my thick thighs.

They seemed to give Michael an idea. “Hey, your parents installed a hot tub near the pool this winter didn’t they?” Michael asked.

“Yeah, why?”

“Let’s take a dip!” He sounds excited as his phone *pinged* repeatedly as he was thumbing through it.

“Sure, sounds great.” I wondered if the soothing heat would calm the ache in my groin from the overinflation I’d done to myself, in the past 24 hours, three times.

“I’m gonna grab the towels and the clothes we ruined in our little party,” I yelled to him as he begins heading down the stairs toward the hot tub.

“Sure. But that’s not my mess. Mine ended in the toilet! At least I didn’t repaint the shower with my ‘party balloons’.” He laughed again as his voice faded down and out.

I shook my head, looking at the mess. Cum was dripping off the walls in the shower as the drain finally unclogged. I cleaned up the remainder and throw our clothes in the wash, praying it didn’t back up—not realizing how backed up things were about to be.

“Hey Michael…” I walked out to the patio and stopped, seeing his briefs laying on the lounge chairs by the pool. “What are you doing?”

“What do ya mean there bud? I’m lounging in the tub. Come on in, the water’s fine,” he said to me, waving me over. I walk closer.

“Why are you naked?” I asked, stinkeying him.

“Come on. We’re just good ole’ friends. We’ve seen each other enough times in the locker rooms.” His phone *pinged* and he grabbed for it. Me, I was just thinking he was texting another one of his wing girls again.

I sighed and eventually giave in, removing my swim briefs and slowly lowering myself into the water, the bubbles bouncing my bait and tackle around like a couple of beach balls. My own phone *pinged*. A text from mom. “Hi sweetie. We decided to stay the evening over at my parents. Hope you and Michael have a good time!”

“Looks like we have the pool to ourselves then,” I said to Michael. “They’re staying at my grandparents for the night. I assume James is too.”

“Well, that’s reassuring.” He moaned, reaching his hand down into the water, seemingly kneading his meat. I can’t tell what going on down there with the water bubbling about.

“Hey. Hey. Don’t make anything messy in here. I don’t want to be in the same water when that cannon goes off.”

“Oh you have no idea…” he moaned again. What the fuck was he up to? We heard a *thump* in the water as it vibrated across the bottom of the hot tub. I felt his foot brush mine.

“Dude, I know we are big guys but please keep your feet to yourself. There’s plenty of room,” I said, pushing it away with my own foot. Only, this felt more fleshy.

“Dude, you’re hanging pretty low there.” I looked at him. His bottom lip was curled in, and he was moaning as he caressed the mass between his legs. He was already bigger than me!

“Dude, you didn’t!”

“I’m sorry. Uhnnnnn… fuck.” we both hear the *creak* below the water as I stand up hastily, forgetting about us being nude, I’m mostly seething with anger now. That was, until he slowly stands, holding what appeared to be softballs in his hands, his cock now standing up right, pulsing and swelling, pumping itself past its 10 inch size. “Hmph… Wa… Was it…. nnnnnnnn…. ggg.. fuck… as senstive fo…. fo… for you?” he sputtered out as I climbrf out of the hot tub. The tube of thick meat was creaking past 10.25” inches. The bloat was looking more fierce on his large dong.

“Holy shit dude! What did you type in!” I helpped him wobble out of the tub. Good thing we had no neighbors, otherwise the fence would’ve been useless at this point.

“NNNNhhhhhuh…. Here.” His hand was trembling as he handed me the phone. I see the numbers.

“What the fuck dude! You wanna look like a fucking watermelon down there! Your fucking balls man! Those too!”

“I’m sorry. I just wanted to live out a fantasy. Having my cock expand. That feeling of pressure you felt…..nnnnnnnhhhhuh..” He clutched his balls as they swelled, and I mean swelled, the gurgling and creaking from his balls now screaming for release. We moved over to the lounge chairs and he sat down on the edge, his balls now dragging the concrete as his sits. His ballooning cock was now inflating past 10.5” …. slightly curving in a downward arch.

“You were already big! You were huge! Why?!” I was desperate to figure him out as I knew things were about to get interesting. The inflation begins to accelerate his cock past 11”, widening out in the middle, leaving the cock looking like a misshapen blimp, fatter in the middle than at the base. The veins were now bulging, wrapping their way around the swelling dirigible like a net, large and pulsing. *Creak* Bloat* Gurgle* *Stretch*

We watched the blimp elongate as his cum balloons now rest fully on the ground, stretching his low hanging and sack and spreading out like self-rising dough. *Glug**GLUG*BLOAT* They spread out further, now beginning to fill the space he once had in his sack. The skin now stretching as his hairy groin continued its over inflation past human proportions.

“Fuck! Make it stop! It feels like it’s about to burst” he cried out, now resting one hand on each side of his bloating blimp of a cock, which was no longer elongating but now swelling up like an overripe blueberry, turning purple as the cock ring forced it to take more size. Creaking noises coming from the balloon now straining against its own weight, pulling him forward as the pull yanks on his groin muscles. His thick muscles flexed as sweat was now pouring from him, dripping down each sinew of his skin tight body. His muscles weren’t the only things that were tight as a vise-like grip took hold of his groin. The balloons were now fighting for space, the balls now exceeding volleyball size as they began approaching beach balls. The jiggle and slosh of each cum dump into the globes was heard, forced on by the ring as more and more packed in tighter.

“Please! You gotta help!” he wailed in pleasure. He caressed the cum balloons spreading his legs further apart as they fought for space between his diamond shaped calves. Each now pushing out against a too tight sack. *Pump* *Swell* Bloat* Stretch* *Gurgle* *Slosh* Pre began to pour out like a river onto the concrete of the pool deck.

I was still shocked at the size. Still going through my mind was what a 13” long, 4” wide penis would look like.

“Fuck, Michael!” We saw the trembling mass bounce and pulse as each round of growth forced on by the ring pounds its way into the now blimp, this monster jutting from my friend’s groin, creaking and swelling. The heat radiating off of it was enough to cook eggs on. Steam rose toward the sun as the pressure built in my friend’s overinflated dong. The sperm bombs were now charging themselves tight they had now stopped swelling, reaching their limit seemingly before the cannon before us. His legs were spread-eagle, huffing and moaning.

“Unhhhh.. *creak* uhhhh. ggggg… *bloat* *PUMP* *SQUEEEEEAAAAALL* AAHHHHHHHHH!” He yelled as a large burst of inflation his over blown cock balloon. It swelled more, hitting the 13” mark, then stopping. Then bloating up behind the head, fatter and fatter. Tighter and tighter as the balloon cried out with another large *SQUEEEEAAAALLL* as the next pump forced more growth into the blimp-like cock before it had time to rest. It now sat at an astonishing 3.5” in width at its widest point behind the head, the swell forcing the veins to hold the tension behind the skin. The cock groaned as more growth fed into it. *Bloat* *Pump* STRETCH*. “Oh God! Please stop!” Michael grabbed on and hugged the balloon as if to halt the swell from coming! Stretch marks were now visible as the red colored skin now grew tight against the cock. The dirigible forced his arms apart, and I latched on, trying to give my friend some relief.

“Oh… nnnnn…ff..fuck!” He looked up at me as be both grabbed onto the cock balloon straining his thighs to spread further apart. *Bloat* Stretch* The stretch marks now becoming more prominent as the veins engorged themselves with new life, swelling the blimp with more growth than any man should experience.

“I’m so fucking jazzed right now!” he rasped as he began stroking the blimp between his legs. The kick in his balls reminded him of their bloat. “Aw fuck!” The balls I’m leaning on now swelled up, putting pressure on the globes as they were forced to create more juice for the cum balloons. The explosive power behind each bloat of the fluid was driving the balls to swell tighter and tighter as they packed themselves to near bursting. They were beach ball balloons now, approaching large beach ball sizes as the whole package seemingly swells for the last time.

*BLOAT* *CREAK* *GURGLE* *STRETCH* *SQUEEEEEEEEEEEEAAAAAALLLL* A long stretching balloon sound echoed in our ears as the massive real life balloons bloated to their absolute limits. Then finally, the squeal stopped, then a leathery stretching sound started as the cock blimp shuddered.

“Oh fuck!” we both moaned out. Our hands still on the cock balloon before us, we felt our fingers spread further apart, no longer able to touch 4 hands together across the flesh of the vein marked blimp. The heat soared as the final bloat pushed the cock blimp to its groaning limit. The cock creaked as the leathery sounds started soft then built into a loud rumble, as the balloon expanded to its widest point.

*STREEEEEEEEEEEETCH* *CREAAAAAAAAAK*

“AAAAAAAHHHHH! FUUUUUCK!” Michael screamed as the cock blimp shuddered to a pulsing halt. The thumping of the beastly dong before us drummed through our ears as the blimp swelled and relaxed from its onslaught. Crisscrossing veins, now pencil thick in some areas, fed the blimp with power as the ring relaxed, though still not releasing the pin prick.

*Ping* With trembling hands, Michael picked up his phone. PumpMe app: Length-13” Width: 4” Girth: 12.6”

“Uh… fuck.. hmph. “ He was sweating now and breathing heavily. Deep grunts came from someplace inside. Michael leaned back on his muscled arms, propping himself up on his right arm as his left caressed the side of the bloated blimp like baseball bat protruding from his now overfull groin. The skin stretched almost paper thin, pushing his muscular body to the limit.

“That was…. hmph… fucking insane…” he groaneds, rubbing the side of his cock balloon. He seemed afraid to move as each jolt sent the bulging blimp shuddering, nearing its bursting point.

“I don’t know how—” I said, rubbing his beach ball sized cum balloons, still gurgling as they attempt to pack more cum in. “They’re packed in real tight. And getting tighter.”

“Hey, Keith!” Michael got my attention from the bulging balloons before me. “Are my balls supposed to felt like this?” he asked as I felt what meant. Every second, they were packing in more cum as the sperm balloons force-fed themselves spunk. The cum factories were now in overdrive from his arousal as he leaned forward, placing his hands on top of his ballooning masses, still pulsing with the urge to grow. The cum balloons now ready for round two….

Part 7: The Filling

“Unhhhuh…. Keith!” Michael moaned out as he began caressing his overblown beach balls. Now reaching 16” across, each ball was filling in, packing the cum balloons tighter as the swell began to increase from his arousal.

“Dude, you have to think about something else!” I tried to get him to calm down so the balls didn’t overpack themselves, force-feeding themselves cum as they engorged. pulsing, veins spreading across the expanse of his drum tight sack, groaning as each bump and jolt from the cum sloshing shuddered the over inflated cum balloons. Vibrations moved visibly across the tight expanse of the overpacked balls.

‘Uhhhnnnn….gg.. fuck. That’s hard to do when your balls felt this backed up dude! Oh yeah…” he added, suddenly realizing I too was just turned into a cum balloon about an hour ago.

“Okay… um. Don’t think of anything Michael. Think of something ugly….” I said as he leaned back on the lounge chair, wincing as his balls lifted a little from the change in position and then swelled to meet the ground once more…

“Unnnnn…” His moaning was sounding like he was in heat. “It feels like I haven’t jizzed in over a month…”

“Dude, shut up! Besides, this is more than a month’s worth in there…. “ I said. “Just, think of something else or you’ll have your balls exploding all over the place.” I felt the spread of my fingers begin to slow down and finally shudder to a halt, sending the overinflated blimp bouncing about, sounding like an over inflated balloon rubbing against itself as the pulse slows down to a thrumming throb. The veins were still feeding the balloons, attempting to force Michael’s balls to accept more fluid.

“Oh thank you, sweet baby…” he said as his hand rested on his forehead, another above his groin. His right hand was rubbing his tight lower abdomen as the stretch and pull yanked on his groin, the meat bouncing with each stroke. The pressure was filling his balloons to their limit, no longer packing in tighter as his sperm factories slowed down. His arousal was dying down.

“Thank god,” I sighed, now feeling the outside of his balls no longer forcing my hands apart. They were reaching 17” now from the last bit of swell they endured.

“You need to figure something out! It still feels like I can’t take anymore,” Michael moaned while his hands ran over the top of his beach balls. “These things are ready to burst. I could feel the throbbing in my balls.” *Bloat* *Creak* Then they reached 17.5” as the balloons fill with more cum as he lost control for a second. “ Unnnnnnhhhuhn …. gg.. fuck!” he screamed as the *stretch* pushed his balls to their limit. Now, with each jostle, they were sounding like two balloons rubbing together, each fighting for space, pushing his large calves further apart. “Oh hot damn…” his lips pursed as he continued rubbing… “this feeling, oh man, of being filled to the brim. The feeling of pressure pushing my ballooning junk to grow and overflow with my cum. These balloons… fuck. Hnnnnnhuh…. Fuck!” he threw his head back and moaned. The groaning from the cum balloons was getting louder as they were force fed cum. *Bloomp* *Creak*

“Stop thinking about it! You’re gonna explode!” I frantically shouted, hearing a deep rumbling coming from the over full and deformed balls before us. “We just need to figure out how to get it out of you before you do pop!” I patted his balls as I stood up. I heard them thrum like a bass drum, hearing a water sound bounce off the inside as the cum sloshed from the sudden impact. “Oh fuck, I’m sorry…”

“UHnn.. Just.. gg. damn… don’t let me explode!” he moaned out, still feeling the tightness of his beach ball sized cum balloons.

I paced around, glancing occasionally at the sweating pile of man meat before us, trying to think of something. “We need more hands for this…” I thought to myself, looking at the blimp of a cock stretching before my eyes, still pulsing and swelling with every bounce and stimulation it received. “We just need him to cum faster…..” I said, then…

“Hey Keith! How’s it going wi…. what the fuck is that! Who the fuck is that!” A loud, familiar voice bounced off our ears. I turned to see Jason, my brother, standing before us.

He walked over, kneeling next to the sweating muscular man. “Hiya bud…” Michael smirked…. wincing as his junk jostled about.

“Michael!?” Jason looked at me then him than me again. “Is that really him!?’’ he seemed scared and surprised. “Is that all him???” He eyed the man blimp before him. Michael shuddered as he feels Jason’s warm breath caress the overinflated balloon.

“Hmph… Yes. That is him.” I rolled my eyes. I saw the lust in my brother’s eyes. I forgot to mention, my brother was a bit of a size queen. And let’s face it, so am I when it comes to things like this. Just never really expected it to get this far. This full….

“NNNNhuhnn… Fuck! Get off! You’re gonna make it worse! “ Michael slapped my brothers’ hands away as we all hear the *creak* *Bloat* *Bloomp* as my friend’s cum balloons now packed their contents in tighter, engorging themselves with cum, the expansion pushing them to 18” wide. “Aahhhhh fuck!” Michael screamed, shooting upright and latching onto his balls, caressing and hugging them, trying to prevent further growth as his balls groaned from the pressure building; trying to prevent the inevitable….

“I just wanted to feel it!” He reached a hand forward. I attempted to stop him but it was no use… he began to softly rub the side of Michael’s distending beach balls as an unintelligible “unnnn… ggg..ha;ds” came from my friend’s mouth, now speaking gibberish as his brain flooded with endorphins brought on by the expansion…

*Creak* *Bloomp* *Stretch* as the balloons now reach past 18.5” in width, a constant leather sound now emanating from the balloons spreading out on the concrete, mashed together and deforming like a couple of overblown water balloons, each jiggling as they spread out.

*Bloat* *Bulge* Creak* “DuDE!” Jason’s voice cracked in arousal. His excited mind was going a mile a minute as his ultimate fantasy ballooned up before him. *Creak* *Bloat* The cum balloons were now packing themselves even tighter, shuddering and groaning with each pump that the ring force fed into these overfull beach balls. A crease was forming at the split in Michaels’ sack where the scrotum separated the two halves, rapidly forming a deep crevasse. Sweat poured off the overfull globes spreading out before us.

“Una.;ahsdf .asdfiue. phh..phh..phh….” Michael was now lashing about, trying to grab onto everything and anything around him as his balloons swelled past 20”. Then suddenly, as if they couldn’t swell any more, the expansion stopped. The globes were now pulsing, the net-like veins crisscrossing, forcing more cum into balls that had exceeded their limits.

“What the hell is wrong with him!?” Jason finally asked, now over excited as a large lump forced out a tent his shorts, straining for release, pre leaking down his leg.

“Dude. You gotta be doing that here?” I asked.

“Doing what?” he said as he adjusted Michael’s meat in front to touch the balls with both hands. The rumbling sound coming from Michael’s sperm balloons now getting deeper as they continue to shudder and bulge, pulsing as they attempted to swell more to accommodate the constant filling they are now enduring, packing themselves tighter and tighter now forced to just accept more volume with little room to grow. *Creak* *Groan* as the bloating balls moan for relief before they burst.

“Huhmmph… huhmmph… please… humpph .. make it.. humph… stop.. “ Michael pleaded, tears rolling down from his eyes as he rubbed and patted the balloons now forcing themselves to take more cum. The cum was no longer sloshing as room had run out, and pre was now shooting out of his bloated blimp as the pressure built. “It feels sooooo tight. Soooo packed! Uhnn… “ *creak* *groan* as the balls pulse more, now covered in sweet smelling funk, glistening in the sun as the balloons jiggled with each burst of cum forcing its way in… “I CaN’t tAkE much moorree! unnnhhhhuh.” Michael’s voice broke in desperate need for relief.

“This… is… “ All of our hands lift off of the drum tight orbs as we stare at the cum, then at each other. Panic building with urgency as his balloons continued overflowing with cum. The globes meeting their limits as the cum sweat seeped out through the overinflated sack of flesh.

“Dude…Your balls are sweating cum!” I look at him, slack jawed.

“UNNnnhhfadf.. Fuck…” he groaned.

*Creak* *Groan* *Glug* *Stretch* As if with one thought we all latched onto Michael’s blimp and bloated cock to hurry along his orgasm. Then Jason, now getting more into it than he should, began undressing excitedly.

“What the hell are you doing?” I yelled at him. “We need this done now or his balloons keep filling. Do you know what happens to balloons when they over fill!?”

“Relax, he still has some time,” he said casually as he quickly stepped out of his briefs, eyeing the head of the bulging blimp before him. “I have an idea to speed this along,” he added as he sensually caressed and kissed the softball sized head of Michael’s balloon cock. Michael groaned as Jason pulled the cock down further to meet his own. Jason’s thick 7 inches was bobbing up and down in anticipation for what I now saw was coming.

No, wait!” I tried to react, only to be mesmerized by the scene, astonished that the blimp before us took it, my hands, Jason’s, and Michael’s all still on his giant cum-sweating balls.

*Groan* *Bulge* *CREAAAAAAKK* “Aaaaahhhhhh! Just fucking do it!” Michael yelled.

With his cockhead lining up with the two-inch sized piss slit, Jason, intoxicated by lust, had already begun sliding in…. “Okay, you asked for it!” he said, and started pushing with force as Michael writhed in pleasure and pain as the cock was now bloating again, this time from the inside as my brother’s cock force fed itself into Michael’s blimp.

Michael’s blimp was now creaking and groaning as it expanded with each thrust my brother pounded into the cock with his. Pressure now searing up in Michael’s balls as they groaned for release, excitedly jostling about as the cum sweat poured off the balloons, pooling under the balls. The cum, having nowhere to go, force fed itself in and pushed the balls to their breaking point!

“Man, this is fucking insane!” Jason said, now full on fucking the blimp, feeling the tight wetness of its confines. The cock was seemingly trying to suck in Jason’s cock as the squelching of the blimp being fucked got louder, pre-cum was forced around them and out. The flow now blocked completely with each thrust in and then spraying out as Jason pulled back, increasing exponentially as finally, Michael’s balls seized, and his legs lock up. The veins in his neck and arms, all across his muscled form, stood out as the cum began rocketing up from the balloons bouncing up and down off the concrete. Six hands and one cock was now enough to send Michael over the edge.

“OOOOO… Man. ewewere.. “ Michael’s lips pursed as sweat pours down his meaty pecs and thighs. “Here it cums…” the balloons shuddered, then rumbled… then, silence.

*SQUEEEEAAAAAAAL* as the cock blimp before us swelled past its 4” width, squeezing tighter around Jason’s cock!

“Oh fuck, I’m stuck!” Jason said as he yanked with no release. The vise-like grip of the extra swell was sealing off the exit from Michael’s 13” blimp.

“Whether or not you’re ready, here I cum!” Then, blast! as the cum began shooting out of the balls, the balloons screaming as the release backed up in Michael’s cock, filling the shaft with jizz, the cum having now where to go but forward.

“Oh geez fuck!” Jason yelled, feeling the pressure against the head of his cock. The shaft blimp before him groaned and swelled past 5” inches wide as the cum pooled in the shaft, then…

“Oh fuck! It feels like I’m cumming in reverse!” Jason, dropping to his knees as the cum forces its way around the cock blocking the exit, the feeling of cum gushing around and into Jason’s penis. The feeling of an orgasm, but backwards.

“Holy shit!” I said. Cum was blasting out of Michael, dousing Jason and me with spunk, but not all of it could get out, and there was still more coming!

“I feel it!” Jason said, dropping his arms down.

“What!? What is it!?” Michael comes off his high, his cum still spilling out of the balloons… into Jason’s balls.

Jason groaned. His hands caressed his previous golfball-sized testicles as what couldn’t get around the cock now force fed itself into Jason, blowing his balls up more, filling them with more seed. Without the effects of the ring, his balls pulsed and groaned as they swelled, dropping down to baseball sized and ready to burst.

“You gotta get me out of him! Before I end up like him!” Jason screamed, writhing about from the feeling of being turned into a cum balloon, now covered in gallons of cum from Michael’s gushing blimp.

I yanked on him, trying to get him free from Michael’s shrinking dirigible, which now deflating around Jason’s cock as the orgasm finally slowed—but the deflation was only tightening and sealing off the exit. No cum was escaping now except into Jason’s balls. *Creak* Bloomp* *Swell* The orbs expanded to football size as the flow decreased, sputtering to a stop.

*Pop* “Finally!” Jason was freed and sighed, rubbing his bouncing balls of cum. The sack distended out into a stretched bag of flesh.

“Unnnh… It feels like I’ve been kicked in the balls…” Jason moaned, rubbing the footballs between his thighs. The balls were shuddering as they too had been filled to the brim, ready to explode. He sat back onto his defined butt, legs curled in with knees pointed to the sky and spread as far as he comfortably could.

“Yea, it’ll do that to ya…” I said, walking up to him. Only now do I realize I’m standing naked in front of Jason.

“Holy Fuck! When did that happen!” he said, pointing at me and still rubbing his throbbing orbs. My thick 9” hard-on still retained its bloated blimp shape from earlier, the sun glistening off the tight, veiny shaft, the head purple and pulsing, dripping with pre as this whole thing had me wound up.

“Geez…. Look at these things! They’re like a couple of potatoes!” he said, going to reach for my balls. I backed away, avoiding his touch. The pendulous orbs swayed back then forward as his hand grazed the bottom, sending a shiver up my spine and a throb to my overblown cock.

“Gahhh… fuck! It feels like I’m about to burst now,” he said as he furiously began fisting his cock, trying to expel their contents. The pressure built into a mind-blowing cum blast that added more to the river of spooge now seeping its way into the pool. This was the final straw for me as I felt my, yes, potato-sized balls seize up and expel their seed… directly onto Jason’s chest and lap, sending us both into another wave of orgasms.

“Hello, what about me?” Michaels huffed. “NNNnm. Damn this thing is sore, and so are these…” he said, rubbing his now 8-inch long, 2¼-inch wide flaccid blimp. He lifted each grapefruit-sized ball, still pulsing with the urge to grow.

Finally, Jason chimes in. “I don’t know about you guys, but whatever happened to him, I want in on it…”
