The Clinic

My little bro squirmed in his seat, the clothes dad had bought for him this morning already way too small.

“Stop squirming.” I said to him, looking down at his sweat covered forehead and red bitten lips. “It’ll make it worse. Best thing to do is ignore it.”

Since our family had entered The Company’s rehoming program, things had been going great! We were listed from the slums of New York State to somewhere in Washington, gated community and all. Sure the change of scenery took some getting used to- but we were acclimmating… slowly.

The hardest part though was the agreement- the caveat for having us be chosen over the dozens of other families. The contract we signed would permit The Company to filter into our water system a cocktail of drugs meant to slowly transform us into the perfect male specimens.

Today little bro had started puberty for real and while it was hot waking up and hearing your little brother’s pleasured groans while he humped his pillow, the twitching was getting to me.

“But it hurts!” he countered, shifting in his seat again in an attempt to get some friction from his pants. “I’m so fucking horny bro!”

He bit his lip and stifled a groan as his body jolted, pants now tighter as his already thick thighs swelled into tree trunks. He was even lifted off the seat from his ass expanding.

“David, be quiet.” Dad said, not even looking up from his magazine. “You’re drawing attention to yourself.”

He wasn’t wrong. The clinic wasn’t as full of people as it could be, but there were still some guys in for routine checkups, and all eyes seemed to be on my little brother. Some just stared, some even went so far as to rub themselves through their pants at the sight. I couldn’t blame them- the serum we were all exposed to dropped our inhibitions to almost nothing, but even then I felt the brotherly instinct to shield David from prying eyes as he went through something I did myself only last year.


David’s eyes widened, raking the man’s body up and down as he stared at the expanse of clothed muscle. David was quickly led away from us and into one of the examination rooms.

~~~

“David, I’m Dr Everest, today I’m going to assess how your body is reacting to the serum you have ingested.” He said, the pair walking into the large room.

David looked around, trying to distract himself from the hunky man leading him in, eyes finding a medical bed off to one side, a series of arm and leg restraints in place on both sides. “I’m going to have to ask you to lay down- to do my examination I can’t have you squirming in your seat.”

David nodded, remembering that this process had been hundreds of times before, both his brother and father included. He sat down and begun to lay back when Dr Everest stopped him.

“Without your clothes, David.” The man said, snapping on a pair of blue silicone gloves.

David blushed, quickly undressing and trying to avoid touching his throbbing erection and aching balls. It was like it was both painful and pleasurable to touch himself- but the worst part was that he couldn’t cum!

“Now David.” Dr Everest said, approaching the table and tying on the arm restraints. “Have you been able to ejaculate at any point within the last 8 hours?”

David shook his head. “No Sir, not since before bed.”

The Doctor nodded approvingly, moving down to tie the leg restraints. “That’s good- it means your testosterone levels will be at their peak for this examination.” He said, finishing by moving back to David’s head.

“One last thing,” Doctor Everest said, producing a ball gag from one of the cabinets lining the walls. “Can’t have you making toomuch noise.” He placed the gag around David’s head, the large silicone ball between his teeth and muffling his voice.

David watched as the man wheeled out a small device on a metal gurney, a series of pumps attached to it along with a glass canister on the back. It wasn’t until he produced a series of pump attachments from the shelf beneath that David realised it was a milking device.

“David, I’m going to measure you for your pump and we can get started. The added stimulation will ensure the flood gates open and we can get a nice bigsample.”

The Doctor stared down at David’s throbbing red erection, foreskin pulled back as the slit oozed jelly thick precum and made his newly grown pubes a sticky, musky mess. The Doctor inhaled deeply as he measured David’s cock against a few silicone moulds before choosing one- the scent of musk and sex and testosterone permeating throughout the room.

“A healthy 9 inches- right on target for your growth.” Doctor Everest said, admiring the thick, vein covered shaft for a moment before resting the appropriate milking mould to the side. “Now to measure your testes.”

David knew what was going to happen and shuddered in anticipation, the Doctor placing some lube in one gloved hand and reached down to grab David’s heavy swollen nutsack.

As if on queue, David felt the rising pressure down below, groans muffled by the ball gag as he surged with growth once again. Instead of stopping however, Doctor Everest continued. He groped, pulled and massaged David’s aching balls as they swelled in his palm, followed by his cock as it swelled another inch upwards.

David’s body was the last to catch up. His nose and jaw widened slightly, more stubble growing on his increasingly squared jawline and travelling down his neck. David’s pecs also grew in size and his shoulders pushed out further to the side. In a few moments he looked a little older than he was before, suddenly slightly too big for the table.

Doctor Everest looked down, pleased as he released David’s balls from his grip. “A healthy young man.” He said, running a hand u David’s sweaty naked body, admiring it as if he was some priced bull or fancy car. “Just like your brother.”

Dr Everest replaced the suction device with a slightly larger one, filling it with clear lube to the brim before unceremoniously guiding David’s cock inside. David groaned at the cold, wet squelch of the device on his cock- but the pleasurable entry couldn’t prepare him for what was to come.

Dr Everest flicked the switch of the machine, the squishy base tightening around his cock like a vice as it whirred to life. Thousands of tiny silicone tendrils vibrated at once, massaging and groping and teasing the entirety of David’s cock as the tremors went down to his balls.

David let out a surprised yelp before his mind was overcome with pleasure, moaning freely into his gag as his cock was massaged and sucked by the powerful vacuum.

Dr Everest watched as David’s muscular body writhed on the table, hips trying to thrust deeper as the machine worked to pull the cum from his aching balls. His own erection bulged the front of his pants, leaking profusely and staining the front.

It would be cruel to leave the boy with no other stimulation, especially after spending so long unable to cum.

David didn’t even notice Dr Everest had undressed until the man was looking down at him shirtless. “David, I’m going to remove the gag now. I want to help you, but I need you to say yes.”

David breathed heavily as soon as the gag was released, however his eyes soon zeroed in on Dr Everest’s huge throbbing cock bobbing up and down in front of his face. It was tan and thick, but the sheer length of it sent him into a hungry frenzy.

“Yes! Yes, god yes just please give it to me!” David moaned, voice drowned out by the SCHLORPSCHLORPSCHLORP!of the machine furiously attempting to suck his soul out from his cock. Dr Everest wasted no time in accepting the man’s request.

Dr Everest moaned as he began thrusting deep into the captive man’s throat, balls slapping his face as David’s greedy throat mimicked the machine on his own cock- trying to drain the man’s balls and swallow down the thick jizz.

“Fuuuuuck! You’re such a better sucker than your brother!” The man remarks, pubes meeting David’s chin as the scratch of the younger mans stubble against his thighs made his erection pulse.

David was in heaven beneath the larger man, lips wrapped around the huge tan cock and throat being fucked into oblivion by the SMACK!of Dr Everest’s hips against his handsome yet boyish face.

It wasn’t long before the combined facefucking, machine milking and scent of sex drove both the men to a thunderous orgasm- David moaning around the elder’s cock as the machine kept pace with David’s first orgasm as a man.

The glass cannister soon filled with David’s release, the Doctor reaching forward and twisting the silicone mould and releasing David’s still hard cock from it’s prison. The excess of David’s release dripped from the opening, covering his cock and pubes with thick, sticky cum that ran down his hips and balls to meet the table.

“Such an excessive release must not be wasted.” Dr Everest said between pants, pulling his softening cock from David’s gullet and working his way down the younger man’s body to lick his cock clean.

The man savoured the rick, creamy, salty spunk on his tongue, not wasting even a single drop and only releasing David once he was properly cleaned. Said man was still in a state of bliss, throbbing cock largely ignored as his face sported a dopey, pleasured grin.

Dr Everest noted his findings and coaxed the spent young man into his clothes before leading him out of the office.

~~~

I watched as David was led out of the examination room, knowing what happened inside. He had probably just had the most intense orgasm of his life and, while I knew that Dr Everest is always available for a physical, was slightly jealous I couldn’t experience that same orgasmic nirvana that went on for hours after.

“He will need to be constantly drained over the next 48 hours.” Dr Everest said. “I suggest you either find a gentleman to assist you, or pleasure him yourself.” The man said curtly before walking off. I watched the sway in his hips, staring at the swell of his perfect, meaty ass before Dad stood up and grabbed David by the arm.

The older man had always been apprehensive to anything sex related, even though I’ve seen the way he stares at the other lustful men throughout the town of Athos- named after the mountain of only men.

The drive home was filled with silence, the strain in David’s pants still not receding as I knew it wouldn’t for at least 2 more days.

“Boys, I need to go out for a while starting tomorrow- you mind taking care of your brother?” He asked me. “And whatever your brother needs, just give it to him, would ‘ya?”

I nodded. “Yeah Dad, I’ll give him what he needs.”

That was the end to our conversation- the night spent with a brief meal at dinnertime and forcefully changing David out of his clothes- which were still marked with sweat and the remnants of other fluids.

“G'night.” Dad said, retreating to his room. I watched his muscular form disappear into the custom widened doorway. I checked on David, who was snoring soundly naked in bed, thrusting his hard dick against the sheets in his sleep. I watched, transfixed as the swell of his ass beneath the blankets hardened my own cock.

I groped my bulge, biting my lip to keep quiet before going to my own room and locking the door.

David could wait until morning, I needed this now.

I fished the pilfered underwear from my pocket, the pair of David’s still soiled with precum and sweat. I inhaled the musky scent, eyes rolling back at the raunchy smell of sex and seed and slightly sterile lube used in the Doctor’s office.

I gripped my cock in my fist, jacking it back and forth while huffing it like a drug. I bit into the fabric to stifle a moan-shooting my load of cum against the hardwood floors as my back pressed more firmly into the door.

I pulled the garment away from my face, looking at the large, thick streaks of painted white glistening on the floor. I wiped them up with David’s underwear still in my fist, tossing it aside.

That could wait until morning too.

It wasn’t hard to turn my older brother into my personal cumdump, nor was it hard to turn me into his twin.

See, we weren’t ever close. Not as kids, not as adults. So, when the time came and we needed to think alike for once, I may have… forced his hand.

I ordered two bottles of pills from The Company™️, both made to turn me into a musclegod and a straight man into the gayest, sluttiest, horniest bottom in the city.

I get to keep the smarts of course.

I wish I could say that I was sorry too, but fuck man. Seeing your straight brother take a “vitamin” with every meal for a week and slowly turn into the ultimate dumb Himbo? It’s fucking hot!

Ass swelling, waist cinching, effortlessly defined and cut muscles, height growth, cock growth, even the sluttiness! All the mental changes hit him at once- clouding his brain with new pleasures that he could only relieve with a dick up his ass. Or, a dildo I placed strategically in his bedside table.

Walking in on your big bro slam his huge tan muscle butt down on a 12 inch dildo just does something to you man. Kissing him and feeling those thin lips inflate into fat DSLs, having your own do the same shortly after…

God I’m hard now. Luckily I have my bro ready and waiting right here. Unfortunately I can’t give him the load he desires- not when I have you, dear reader, to come here and fuck both of us.

Door’s unlocked, there’s the pills and a glass of water as you walk in.

I’ve always wanted to be a triplet.

Ricky Ross was a playful youngster who was more often hauled home by the cops than not. A kid with no daddy to call his own and a taste for trouble, the little guy was practically guaranteed to spend miserable teenage years locked in juvie for talking to people he shouldn’t have been.

It wasn’t that time, however. He still had at least a couple years before everyone expected him to fall off the deep end and until then, Ricky was gonna make it count!

He would sometimes take rides with his friends older brothers; he got along better with them anyway. Driving down the highway was peaceful to him and he’s sometimes think of saving all the money in his piggy bank and buying a car to jet off down the road and never look back, but that was big kid stuff and he didn’t like to think of running away too much; his mother would be scared to death!

They had to stop for gas one day though, a stop that wouldn’t have happened any other day save for one of the twin teens forgetting to fill it up the night before. While they were arguing, Ricky decided to use the bathroom and maybe scratch something into the door or wall while he was in there; just mindless mischief that doesn’t really hurt nobody.

While there though, he found something much more interesting.

Carved into the wall was a hole, smoothed out and with various graffiti marks detailing how you’d find the “best blows in town” or “fucking ace hole”.

Ricky decided to stick his small cock and balls through as a joke, just to get some thrill out of doing adult things and riding the slight high as long as he could. However, when he tried to pull his tiny package back out of the too big hole, as of like it was alive the thing closed shut, surrounding his package and preventing him from pulling out.

Ricky was confused for a second, unable to figure it out before he realised he was somehow stuck with his dick and balls on one side and him on the other.

Meanwhile, inside the store the twins were paying for the fuel. There were two workers, seemingly the hottest gas station employees ever with muscles upon muscles and chiseled features not seen in this kind of area in decades. Simultaneously they both got a signal inside their heads, a connection meaning one of their magical traps was sprung.

See, these two weren’t just employees. They both knew a touch of magic and after spending their time in places like Sam Fran and Palm Springs making the hot people hotter, they enjoyed taking a break and “relaxing” in the middle of nowhere talking the day away.

They couldn’t have these two interfering so while one, the redhead covered in freckles with hair like fire offered each boy a chocolate bar as being their first and only customers of the day, laced with magic of course, the other went to check on who exactly sprung their little trap.

He walked inside and instantly all movement ceased from whoever was struggling on the other side of the door. Peeking inside the man was greeted with quite the underwhelming package, deducing that this person is in serious need of his magical adjustments.

He kneeled before the hole, spitting on his fist to wet it before massaging the little package until it was forced to grow hard. It changed very little, maybe two inches at most and as he kept going a high pitched whimper resounded as a dribble of cum flowed from the tip.

He smirked, this was going to be fun.

The sight of the blonde muscle god, 6ft5in of big and tall muscle kneeling before the small 2in cock and worshipping it like it was near orgasmic as he thought. The magical master shuddered at the reaction if someone entered before he’d finished, caught in the act.

That was impossible though, right now he needed to focus. He swirled his tongue around the head again and again until the foreskin returned, then continued until he was sure it would cover the soon to be mushroom and hand off and give some needy cocksucker something to slurp on.

He continued, taking the entirety of the shaft into his mouth and sucking hard, drawing inch after glorious inch out into the world as he made it grow longer and longer. He let it pop off at a mighty 12 inches long, but still fairly skinny. He got right back on, instead now staying put as he sucker and letting the meat expand to meet his cheeks and throat.

Soon it was becoming unbearably thick, nearing beer can proportions when he finally released it.

Ricky on the other side was in an orgasmic high, unable to do anything but stand there on shaky legs, riding out each and every one of his orgasms as his tiny balls pumped out barely a dribble of cum each time.

Seeing this, he got to work adjusting the balls.


Back inside the twins were currently writhing on the floor as their bodies grew identically into more handsome and slutty forms. The redhead watched over them, seeing their muscles expand out of their twig bodies and asses grow fat and clap when they twerked on the floor, filled with the desperate need to suck a fat cock and guzzle it’s cum.

They compromised by furiously making out, tongues lashing as their lips plumped up and their heads were full of memories servicing only the biggest country dicks as twin cockwhores.


They soon reopened their eyes, staring back into their own faces as their square jawlines clashed again and again, desperate to kiss the beautiful jock in front of them.

Back inside, Ricky’s balls were getting their own treatment, seeing the pathetic nuts hanging down from such a gorgeous cock just wouldn’t do.

He stuck out his finger and thumb, making a makeshift cockring and pushing more and more growth magic into them.

They inflated, throbbing and filling up with gushes and waves of churning, bubbling cum. Enough testosterone to fill a whole football team packed itself in there and when he released, they were ripe and ready to go.

Ricky moaned, voice cracking as testosterone flooded his system and skyrocketed his growth from years to seconds. Meanwhile his mystery benefactor was lining up his pink pucker, lubed with spit and pressing that fat mushroom head against it before slamming down against the wall, engulfing each veiny inch.

He set at a brutal pace, pushing off the adjacent wall and slamming his muscle ass back down before he had a chance to breathe.

Ricky was grunting now, groaning as orgasmic pleasure washed over him. His orgasmic rhythm was back, this time spraying volleys of seed into the tight cavern.

“Wh-what’s- what’s *SPURT* haPPENING TO ME?”

He began, voice cracking and growing deeper as his body grew in height and packed on hairy muscle.

“It f-feels *SPURT* fEels fuckin’ *SPURTSPURTSPURT* fUCKIN’ AMAZING!”

He would now towering over the divider, the same immense 6ft5 of his new cocksleeve had he not bent at the knee. Muscle piled on as his back widened so far and so fast it broke the lock on the door, the thing swinging open and allowing Ricky’s big hands to find purchase on anything but the wall.

“RRRRRRRHHHGGGHHHH FUCK YES BRO MILK MY-“ *SPURTSPURTSPUUUURT* “FUCKING COCK!”

This was it, the crescendo he had been teetering on that would seal his fate. A pelt of hair grew up from his denim covered legs that had magically grown along with him to his torso and the shredded remains of his shirt, finally climbing up to grow a perfectly styled and trimmed stubble, then beard on the handsome square jaw.

“FUCK BRO, FUCK DUDE IM” *SPURTSPURTSPURTSPURT SPUUUUUUUUUUUUURRRRTTTTTTT*

FUUUUUUUUUUUUCK!!!”

Ricky, now Rick, let out a primal roar as he filled the man’s already filled guts with at least a gallon of seed, the gloryhole widening and allowing his cum-covered cock and balls to be yanked through.

His twins were on him in a second, breaking their little make out session to push through the seemingly unlocked door to drop to their knees and start cleaning their daddy’s cock. They each moaned at the raunchy taste and came in their pants at the site of his muscular body covered in sweat.

“That’s it boys, clean your daddy’s thick bitch-breaker.” He said, the country drawl mixing with the low baritone. He looked to the alternate stall, the door wide open and the big blonde that had taken his meat was standing there, cradling the bulge in his abdomen from the sheer output of seed.

He nodded and smiled at Rick as he sauntered out the door and back to his work, the country man shoving his meat back into his pants and leaving with his two boys back to their truck.


The man leaned against the car as his cockwhores climbed in the back, eagerly sucking face to taste the remnants of his cum on each other’s lips. How he managed to wrangle two hot studs from a nowhere country town was beyond his luck, and with any more he’d be able to quickly spirit them away and be his houseboys in the city.

He took one last look at that gas station, the two men inside waving him off as he smiled, jumping in the front and speeding off down the road, all memories of that nowhere town and dead-end life forgotten as it was replaced with the cocksure persona of Rick Roserider, one of the most popular gay pornstars there were with his two newest stars in the back.

All memories of Ricky Ross piled into his fat balls; he was ready to go again. “Will one of you two sluts get over here? I need to blow a fat load and the first one to get here gets it!”

The twins couldn’t climb over into the front faster.

My Daddy wasn’t with us for long; me and my Pa said goodbye to him just after my 9th birthday.


We had a lot of fun times, despite me only being adopted by the two men for less than a year. I didn’t realise it at first but it was soon way too quiet in the house.


One afternoon I had found my Daddy’s old chain necklace in one of the drawers. I can’t remember why I was looking for stuff, probably something for school.

He wore it everywhere and every day, I’d see it mixed up in the dark hair of his chest, glimmering in the sun. I don’t even know why he wasn’t buried wearing it but I guess that doesn’t matter now.


I felt a need to put it on, I didn’t even have to unclasp the back to slip it over my head.


All of a sudden I felt huge!

My legs got so big so fast I broke out of my shorts and underwear, then my stomach got big and wide too and it travelled up to my chest.

I never knew I could have a chest this big, but they inflated so huge and fat I couldn’t even see my feet afterward, and my nipples were big as well!

It wasn’t long before I could start to see something below my pec shelf, but curiosity quickly turned into surprise when I realised it was my dick! I was huge now, at least 9in for sure.


When the changes hit my shoulders I could feel it in my brain, like an itch being scratched as my mind was filled with new thoughts and memories. My Daddy has infused his soul with this necklace after dying and I was gonna be the new man of the house.


I grunted as my shoulders pushed sideways and packed on muscle, my arms throbbing as they grew huge along with my hands. A layer of fur started to grow that I was sure would thicken with time.


I’d aged a whole decade! Gone was the scrawny kid from before, replaced with a thick muscle jock that’ll show his Pa just what this new body could do!

Looking back in the mirror I saw what had happened to my face. My jaw was now much more square and covered in stubble. I looked down and smirked, snapping a pic to send to my Pa as he came home from work.


A little editing and a cheeky “Guess who?” Was all I needed for him to send me back a pic of his fat bulge.


Who knew; Daddy was a bottom.

Story for @fathernature83 cause he makes such hot stories!

Antonio was your average Italian-American teen, large, loud, and loving towards the ones that mattered most: his family.

Said family consisted of him and his two younger brothers, Giovanni and Luca, and until recently their Mother. She had raised the boys all on her own until sickness took her away, meaning one of the primary sources of income was now off the table as well.

With no father figure to call their own, the 18 year old Antonio quickly fell into the role of a surrogate father figure, ferrying the middle child Giovanni to and from school, and caring for the young Luca all on his own. Times were getting tougher and money wasn’t coming in quickly enough; that was until Antonio stumbled upon a grand opportunity.

A company in Brooklyn had offered a grand sum of money in continuous payments to the first man to accept their lengthy list of requirements and sign his name on the dotted line. And after putting the boys to bed with their neighbour watching over them, Antonio left into the night.

He came across a large building that seemed to glow from within, the massive office/apartment style construct looked out of place amongst the much smaller surroundings. He stepped inside, being greeted with a cheery woman, far too cheery for late work.

He stepped up, saying he was here to sign the contract and participate. She gladly accepted and ushered him into an adjacent room. Inside sat a stern looking businessman and a stack of papers. He barely read any of them as a signature was scribbled down the bottom.

Snapping them shut in a briefcase, the man unlocked a final room deeper within the building; a stark white medical lab where someone in a lab coat was already preparing. Just what had he signed up for?

The man shook his hand and introduced himself as Doctor Matthew, his eyes flicking to the V in Antonio’s shirt before coming back up to meet his gaze. “Ready to begin?” He asked.

“Yeah, yeah, let’s get this done so I can get my money.” He replied curtly, the Doctor instructing him to remove his shirt at once, but put it back on before the final stage.

He complied, the man rubbing his nipples with alcohol solution before applying a cream to them, then pulling out a syringe filled with fluid and injecting a half into each pectoral, before finally producing a tablet and some water for Antonio to swallow, which he did as he pulled the material back over his head. He complied without hesitation: He loved his family after all.

As soon as the capsule hit his stomach, things began to change. His white shirt which at one point was looser on his frame became unbearably tight as his muscles expanded instantly, each deeply cut abdominal jutting into existence with a throb, his back arching onto the medical bed he hadn’t realised he fell back into. With a loud *CRUNCH* it didn’t feel so long anymore, it was like his spine had stretched and now his feet dangled off the end.

His shoulders shot out to either side, nearly breaking the neck of his shirt down the middle. Twin cannonballs grew in their place as his knuckles popped and lengthened. A glance at his hands revealed the digits had grown and thickened, his palms now enormous as his now vein covered forearms led to seam-splitting biceps.

He let out a grown as a tightness spread from his feet upwards, it was like his shoes were too small. His theory was confirmed as his feet cramped inside, Antonio toeing them off to see his socks begin to tear. His calves only sealed the deal, legs lengthening as his calves and thighs made his jeans look plastered on, the thick thighs and shapely legs only making him look sexier. This continued until the forces met in the middle.

He was panting now, breathing hard as two cum gutters found their way to his lower abdomen, his bulge stirring momentarily before his hips were listed off the surface by the inflating rear. The massive cheeks wobbled as they fought for space, resulting in a tipping sound reverberating in the room as the seat of Antonio’s pants could no longer contain his fattened ass.

The final wave of heat came to his neck, thickening it and turning the sounds from boyish moans to manly grunts, his brows furrowed, jawline thickening as his cheekbones increased in size, eyebrows thickening and his hairline receding ever so slightly. The new Antonio breathed heavily, rubbing his sore jaw and feeling the roughness of the stubble there. He looked around a decade older now, 28 years old and already daddy material.

“Is- hah- is it over?” He asked, surprised at the deep richness of his voice now. His question however, would soon be answered.

Antonio felt a stirring from his chest, the site of the injections and his cream-lathered nipples tingling incessantly. Each beat of his heart brought a wave of pleasure starting from his chest. He watched with both horror and awe as his pecs swelled and grew into place, then they began to push further. It soon looked as if Antonio had spent his whole life on a rowing machine, the meaty slabs now having a cleavage between them.

He gasped as his nipples expanded accordingly, the dusky buds widening and fattening into perky teats leading to pendulous pecs. He reached up to feel the heavy weight, almost a slosh coming from them as Doctor Matthew saw his chance to intervene. Antonio didn’t know where he pulled them from, but two pump-looking devices were soon strapped to his pecs and over his nipples, the man turning the mechanism on without a word.

The Italian was going to ask what he was doing when he felt it, a pressure abs tug at his nipple as it lengthened, the hard bud being pulled inside the vacuum until a plus felt like it was released and a torrent of milk flowed from the new man’s chest.

He let out a string of curses as his pecs were thoroughly milked, never losing their roundness or perkiness, but still somehow pulping out more and more creamy fluid. Eventually the Doctor turned off the machines, pulling the pumps from the man’s chest.

The doctor smiled and helped the new adult to his feet, still unsteady from the new height and weight plus the pleasurable milking.

“What did you do to me?” He finally worked up the courage to ask.

“We wish to revolutionise sports supplements, however the basic formula needs a living host to create it and we did not wish to use cattle. So, we enlisted your help.” He explained. “The growth is a side effect of the hormones I injected directly into your new milk factories.” He said, pointing and prodding at Antonio’s chest.

“Now, there is one final thing before we will fully reimburse you for your participation.” He quickly added, pulling a box off the counter and opening it, revealing what looked like a cigar and a lighter.

“This is not your regular tobacco product, it’s a complex mix of hallucinatinogens and mind-altering solutions, guaranteed to let you get used to your new life, Sir.” He handed Antonio and produced a lighter, igniting the end and pushing him out the door and through the small room to the main area.

Antonio took a puff of the hot-cigar, huffing in the smoke and letting it cloud his mind before clearing things further, filling him to the brim with experience and memories. Antonio, now Tony stepped into the early morning light of Brooklyn, leaning on a nearby wall to finish what was left of his parting gift.

From across the street he heard a whistle coming his way. He looked up, unaware a side effect was also the change in libido and sexual arousal, as his gaze stopped on a younger blonde man, waving at him and shooting a grin his way.

He finished what was left of his cigar, and judging from the time on his watch, Tony had a couple hours to kill before he had to wake up his boys. Striding across the street he cane chest to face with the man. He outstretched his hand. “Tony.” He introduced. “S-Steven” he replied.

Tony smiled, the guy was cute but obviously new to someone of his caliber. “I saw you watchin’ me. Like something you see, Steven?” He questioned. The other could only nod in response as he stared at his pecs.

Tony chuckled and walked off in the direction behind him. Tony could’ve sworn the kid had cum in his pants from the sight of his ass alone as he got a glance between the ripped seams. He turned down what he knew was an alleyway with a makeshift bench, perfect for straddling Steven on and milking every inch of his young pole with just enough time to spare and get home to make his body breakfast.

After all, Tony loved his family.

Coach Matthew needed new players, desperately.

He was all out of options too, all his stars were knocked out on the bench due to injury or other commitments and he no longer had his College team ready to compete!

He scratched his beard thoughtfully as he stared into his mug of coffee. The game was in only a couple hours, how in the hell could he create an entirely new team? It was impossible! Unless…

He stood and rifled through the drawers of his desk. He had sworn that these wouldn’t be used unless there was an extreme emergency.

He pulled out an unassuming orange pill bottle, the contents rattling about.

“B34R Pills”. He read aloud. “Jock edition- Football”.

B34R was originally a virus that had swept isolated parts of Europe and other countries, rooting itself in human DNA only to be harvested by interested companies and used for fast-acting supplements, capable of turning even the scrawniest of geeks into musclebound giants in seconds.

The coach looked out his window at the empty field thoughtfully and made his decision.

———

Timothy wasn’t a very fit boy, in fact, he wasn’t fit, period. He was small and slender, completely unfit to run a mile let alone do it constantly, holding a ball.

So, when he got the email from the school Coach to come in early and speak about something urgent, he thought it was unusual. The college freshman wasn’t sure what was going to happen, nervously sitting down and accepting the water cup he was given.

The moment a sip of the cool liquid slithered down his throat, things began to swell.

In seconds his scrawny shoulders had ballooned outwards and his neck thickened considerably, feeling his voice to animalistic grunts. “Wha-“ he let out before a symphony of grunts and moans left his mouth.

“Calm down boy, soon you won’t remember anything that happened here. Only football, get it? Though you might be thinking of other balls after this too.” Coach remarked, watching the man’s lats fan out as his arms swelled like a gorilla’s.

Tim’s waist tightened as his abs came in one after another, followed by his thick thighs and shapely legs, leading up to a muscular ass and a sphincter that would be permanently virgin tight due to all that round muscle.

Tim’s pecs ballooned in front of him, a pelt of black hair taking root all over his body and giving him an effortlessly scruffy and sexy look. This was finalised with the reshaping of his face into a handsome smirk.

Tim’s eyes fluttered as his brain tried to work through the pleasurable stupor, his cock and balls twitching and pulsing as more and more growth surged through him. It was getting hard to think, especially with his cock rock hard and his balls so full. ‘Fuck, gonna need one of those cheerleaders to drain me. Not the bitchy girls, one of the hot twinks’ll do.’ He thought, cognitive function slowing to a halt.

Coach looked at the newly christened jock, helping the man to his feet. “How do you feel son?” He asked.

“Fucking great Coach! Gonna need more of that stuff when I get back from- Uh…” he trailed off, meaty hand coming to fondle his balls, neatly tearing the fabric straight off.

“Go on then, can’t have you fucking somebody on the field.” The older remarked, watching the jock bound out of the room and no doubtedly down the halls to eventually find a guy willing to deep throat his 11 inch pole.

“Boys will be boys. Now, who’s next?”

When Jonathan asked Santa for a “pair of huge tits” for Christmas, he didn’t expect to wake up to this staring back at him from the mirror!

At first he thought there was an intruder, but when the plucky youngster had moved his hands up defensively, he could tell that his reflection was actually the stranger in the mirror.

Now, Jonathan has the nicest tits on the block, complete with super sensitive nipples and a carpet of hair that won’t ever shave off, no matter how hard he tries. Fortunately, his new friends don’t seem to mind, grabbing a meaty handful or letting their talented tongues speak volumes.

When Coach asked Johnny Walker to take his keys and go to the locker room, he didn’t think anything of it.

Final period of the day and Johnny wasn’t exactly looking forward to more AP English, he took the lanyard of keys and whistles and went to the locker room as asked, unlocking the door and stepping inside. He saw nothing out of the ordinary, save for a strange cap sitting on one of the benches with a sticky note taped to it reading, “try me on.”

‘Is this a gift?’ Johnny asked himself, placing the lanyard over his head and approaching the lone hat. He tore off the note and looked inside for anything that may be a prank. Seeing nothing however, he placed it on his head.

Immediately things felt off.


Johnny’s head felt heavy and dizzy as he braved against the bench the hat was sitting on. He grit his teeth as his dizziness grew worse before subsiding. He pulled away, noticing himself in a nearby mirror. He didn’t look… correct. Normally his head would barely come above the bottom glass piece but this time half his head was too tall for it entirely.

He felt a surge of energy as his entire body now felt strange, not just his head. He sat down on a communal bench, unable to do anything except ride out the waves of pleasure and pain as his body grew and expanded. His arms hurt especially, bursting from his sleeves as they grew more and more and more, almost inhuman.

His pecs were next, pushing out like twin peaks as his nipples pressed against his shirt, screaming to be touched. Johnny let out a strangled moan as his abs popped into existence, four rows of hot slabs of muscle. One after another they cut and grew and swelled, making for excellent valleys and cum gutters.

Johnny’s legs were next, thick hairy thighs almost breaking his XXL shorts clean off as his calves followed suit and his feet tore open his shoes from the inside. He whimpered, the hair on his head growing out into a messy unkept cut instead of the nest trim he always had.

The door to the locker room opened suddenly, standing there was the Coach in all his masculine glory. “Damn boy, still not done? You must be resisting the changes then.” He remarks, making his way over to the helpless Johnny. “Come on son, you’re almost there. Just gotta let this last part happen; here, I’ll help.”

Coach’s big, warm hands came to cup and rub the boys bulge, coaxing small bursts of growth as Johnny’s face grew more rugged and angular, his neck thickening until his voice had dropped several octaves.

Coach carefully wove his fingers around Johnny’s waistbands and pulled the shorts and underwear down, revealing the little, leaking cock. He looks on with admiration as his lips made their way around the oozing head.

Johnny let out a grunt and groan as his instincts told him to buck wildly into the wet cavern. As he did, every thrust brought with it a new stage of growth, soon turning the small cock into a thick behemoth with bull balls to match.

Coach moaned and slurped on the appendage, drawing the memories of nerdy, scrawny Johnny into his overfilled balls and replacing them with being the hung assistant coach, Jonathan.

The newfound man bit his lip as his hands came down to push the older into his crotch, cock pulsing once, twice before unloading his thick spunk into Coach’s hungry maw. He looked down at the man, throat bulging out as his seed fills up his mouth before pulling out and spraying the excess on his face.

Jonathan smiled. “Heh, sorry coach. You know how I get when I’m horny.” He said. “Don’t worry though, I’m alright to teach the class now. You take a breather old man.”

Miguel didn’t even recognise that picture in the background anymore. It felt like lifetimes away but had only been two years at most.

When his older brother came back from the army looking like a super soldier, Miguel was determined to find out what had caused the family’s shrimpy genes to be overridden.

He snuck into his brothers room after he left for the day, rummaging through camo coloured rucksacks before finding what looked like a sealed metal box. He pushed and pulled at it, trying to find an opening when suddenly a *click* resonated.

He looked to see that a panel of the box had been pushed in and could now be slid out. Doing so revealed a plethora of syringes and needles, all housing the same glowing blue substance.

Miguel hesitated before pulling one out, no longer would be be a victim of his classmates, no more would be ever struggle to keep up when running. He was determined.

Miguel was also fortunate, having a mother as a nurse meant he picked up how to inject things safely. He lined up the needle into a vein in his arm, pushed it in and released the stopper until the entire thing was safely inside his body.

As he pulled the needle out his arm spammed uncontrollably, flexing and writhing as the feeling spread throughout his body. The boy writhed on the floor as his muscles began to expand and contract all at once, forcing everything to grow.

His back and shoulders shot to the sides, the wide expanse of his lats causing the small shirt he was wearing to be destroyed. His back arched and whole body stretched as height was added in waves, going from small for his height to rivalling a fully grown man. The hot swell of his pecs and tightening of his abs meant that he could no longer see over his chest, and his growing biceps, now the size of melons, meant that moving his arms with much dexterity was challenging.

Next his legs expanded all at once, thick thunder thighs and diamond shaped calves led to massive feet that burst through his shoes. All the while his ass and hips was inflating, becoming two jiggly mounds that would make Latina girls jealous.

Finally his face and neck began to change, his twitching and pulsing cock and balls following suit. His boyish features remained, though the bones beneath them promised that his jaw would be square and imposing yet his eyes would be mischevious. His neck thickened and voice lowers to pleasured, guttural moans as his cock burst from its prison, 11in long and extremely thick, drooling hot precum into the valleys of his abs. His balls weren’t much better, huge and swelling with potent cum.

Miguel panted as his body lay there, naked and huge and perfect. He turned his head at the sound of footsteps, his older brother standing in the doorway looking unimpressed. “Miguel, those were meant to make me bigger, not you. In fact they were made for me.” He said.

“Sorry bro…” Miguel weakly let out, the exertion of his transformation wearing off into hormone induced horniness.

“They were made for me but you took one. It looks like because we were related instead of making you grow, it turned you into me. Or, tried to. You’ve gotta be at least 18 now.” He says, walking over and eyeing Miguel’s cock begging for attention.

“You’re joining the army, no option to say no either. Don’t worry, the guys at the base are gonna love you.” He says, chuckling as he whips out his phone and calls a number, leaving the room.

When Brodie slipped on the amulet around his neck he didn’t know what awaited him. All he could do was fall to his knees as the surge of growth overtook his nerd body.

His pimply face changed into one of pure cockiness and masculinity, home was the double chin and replaced with a lantern jaw, perfect teeth and eyes that begged anyone looking at them to come to the bedroom.

His body inflated with hot muscle, pumping over and over again as his brain was filled with endorphins, not just giving him pleasure beyond belief but also draining any excess smarts and changing his brain chemistry around.

Finally, the amulet completed its purpose with changing up reality, making it so Brodie was never a nerdy slob. Anime posters and figurines that once lined the walls were replaced with weight kits and shelves full of protein powder. His discrete magazines changed from bouncing breasts to meaty cocks and tight bubble butts.

Brodie stood back up, the force of his transformation shredding his shirt in the process. He caught a glimpse of himself in the mirror, brain whirring before he let out a cocky grin. “Fuck bro, that pump was great!” He let out a flex and pose, one that kept the bros in the football team coming back for more. “Gotta text the bros, see if anyone wants to come by and -unf- suck my fat cock!”

His low grunts only grew as the front of his shorts pulsed and expanded, going from a measly two inches that blew after a minute, to an imposing 11in pole covered in veins with balls to match, able to go on for hours of relentless fucking.

Brodie looked over at a tripod, placing his phone in the stand and pressing the button for a delayed picture.
