Undies request

Me: a 5'6" slightly balding 39 year old. Been working out 6 days a week 15 months. Hold most muscle in my thighs and chest.

Where are they: sitting on a bench in an empty locker room abandoned

What are they: some form of jockstrap

The locker room was empty. Dust, mold, flickering neon lights.

He, 39 years old, one meter and sixty-eight centimeters tall, with his slight baldness spreading, sat down on the creaking wooden bench. He had just finished working out. His chest and thighs were his strong points, after 15 months at the gym. But the rest... the rest was average.

He took off his sweaty clothes. In his backpack, at the bottom, he found something he didn't remember putting there.

A jockstrap. White. It looked old, worn-out, but the fabric was strange. Warm. As if someone had just worn it.

He took it in his hands. His fingers trembled.

"What... what is this?"

But his hands, as if they had a will of their own, began putting on the jockstrap. The fabric clung to his hips. Warm. Too warm.

Then it began.

A heat exploded from his lower abdomen. The sweat, already present, became copious. Streams running down his back, across his chest, down his legs.

"Ah... what..."

A moan. His voice cracked, lowering.

His bones cracked. His vertebrae lengthening, one after another. He felt his spine straightening, growing. One meter and sixty-eight became a memory. One meter and seventy. One meter and seventy-five. One meter and eighty-eight.

His shoulders snapped. They widened. His collarbones lengthened. His back arched, his lats swelling like wings.

The muscles. All the muscles began to swell. His pectorals, already developed, exploded. They became two massive, heavy shields. His arms swelled, his biceps exploded, his triceps became defined. The veins surfaced, thick, bluish.

His abs emerged. Eight carved, perfect squares. His waist narrowed.

His thighs. His thighs, already strong, became tree trunks. His quadriceps swelled, his calves widened. His buttocks lifted, becoming two firm, hard spheres.

The jockstrap stretched tight. His penis grew. Swollen. Hard. The bulge was enormous, obscene.

"AH! YES... FUCK!"

He moaned, his voice now deep, hoarse.

His head. He felt his head itching. The baldness. His hair was growing back. Thick, dark, shiny. It covered his head like a perfect mane. His hairline was becoming full again, youthful.

His jaw snapped. It widened. His chin became massive. His beard thickened, not only on his chin but along his entire jaw. Defined, thick, well-groomed. Stylish. Like a sexy young man.

His face became younger. His skin tightened, the wrinkles disappeared. His features became younger. Twenty-nine years old. Perhaps twenty-eight.

Sweat poured copiously. From his forehead, his chest, his arms.

One final jolt. His entire body contracted. His muscles tensing, pulsing.

Then silence.

He looked at himself in the broken mirror in the locker room.

He was no longer himself.

He was a stylish young man. Almost one meter and ninety centimeters tall. Muscular, well-proportioned. Huge pectorals, sculpted abs, veiny arms, broad shoulders.

His thick beard framed his chiseled chin. His hair was wild, dark, perfect.

The black jockstrap contained an enormous bulge. The long cock could be seen from the shape it made in the fabric.

His ass was firm, round, perfect.

A slow smile appeared on his young face.

"Shit... look at me..."

He flexed his bicep. The muscle swelled, monstrous. He looked at his body, his broad shoulders, his massive chest.

He turned around. His ass was perfect. His thighs hairy, muscular.

His hand moved down to the bulge. It was enormous. Pulsating. The desire was animalistic.

"Tonight..." He murmured. "Tonight I'm going to have fun."

He was ready. Gym, girls, guys, anyone. His body was a weapon.

And the jockstrap was his new beginning.

Shapeshifter Fratbro Madness

AI GENERATED STORY

The Sigma Rho frat house was thick with the scent of sweat, stale beer, and testosterone. Music thudded from the floor above, the distant sound of bros shouting over a video game match echoing down the hallway. In one of the side rooms on the lower floor, Tanner lay splayed out on his twin mattress, still in his tank top and gym shorts, his chest rising with heavy, post-workout exhaustion. The fan spun lazily above, wafting the heady musk of jock sweat and fading Axe body spray.

Outside his door, something moved. Slithered. Not walked—slithered.

The shapeshifter had been watching this frat for weeks, studying every gesture, every laugh, every bro hug and chest bump. But it was Tanner who’d caught its attention. The golden boy. Built like a linebacker, thick thighs straining the seams of his shorts, his gym tank clinging to a sweat-slicked chest, curly brown hair matted from hours at the gym. Dumb. Loud. Perfect.

The creature's form pulsed against the door. Fluid. Undefined. Alien. Then, a subtle shimmer of skin, a ripple of muscle as it molded itself just enough to work the knob. It slipped in.

Tanner stirred.

“Yo, that you, Bryce?” he muttered, rubbing one eye.

The shapeshifter moved fast.

A black, tendril-like limb wrapped around Tanner's throat before he could scream. His body flailed—arms pumping, feet kicking—until a final jerk and thud settled him limp against the sheets. The creature towered over him, twitching with anticipation. The room dimmed, as though the walls themselves knew something sacred and filthy was about to unfold.

With a hiss, the shapeshifter loomed over Tanner’s unconscious body, claws slipping beneath the hem of his tank top. Then it began.

Skin peeled. Bones stretched. Every fiber of Tanner's body was scanned and copied. Inch by glorious inch.

The creature shifted.

His legs lengthened, bulging with muscle. His chest expanded, tank top now hanging from broad, sweat-glistening pecs. His tan skin bubbled into place, curling into goosebumps. Hair sprouted—exactly the same as Tanner’s, right down to that little trail from his navel to his waistband. His voice clicked into place last—deep, dopey, smooth as a fratboy shotgunning a beer.

“Duuuuuude…”

The shapeshifter—now Tanner—groaned, flopping back onto the bed. He lifted one arm and sniffed.

“Bro, what the fuuuuck…” He laughed in Tanner’s exact tone. “This is so rank, dude… smells like pure gym and cum in here.”

Outside the door, there were footsteps.

“Yo, Tanner? You good? Sounded like something fell.”

The new Tanner sat up quickly, his face perfectly matching the real one—brown eyes wide, hair tousled, gym tank clinging to his sculpted torso. He cleared his throat.

“Uh, yeah bro! I’m chill. Just… tripped over my creatine tub again,” he said with a dumb chuckle. “Totally good. Go back to Mario Kart!”

There was a pause.

“Classic Tanner,” his fratbro mumbled, footsteps fading.

The imposter waited.

Then locked the door.

And smiled.

Now alone, the shapeshifter stood in front of the mirror above the dresser, admiring his new jock body with a low, horny growl.

“Fuuuck, I am Tanner…”

He flexed.

The tank top rode up, revealing his shredded abs glistening with sweat. He smirked, lifting the shirt over his head and tossing it aside. His thick chest rose and fell, nipples stiff, veins bulging along his arms. Every breath felt like a power trip. Every twitch of a muscle, every lazy blink, was a thrill.

“This body’s built for dumb fuckin’ goonin’, bro…” he muttered in Tanner’s voice, voice dropping into a horny drawl. “So big… so fuckin’ hot…”

He tugged the waistband of the gym shorts down slowly, hips rocking forward. Underneath, Tanner’s cock flopped out—thick, already twitching, precum glistening at the tip.

“Oh fuck yeah…” the shapeshifter moaned, tongue lolling from his mouth. “Bro’s packing. This cock’s a weapon.”

He gripped it immediately, veins bulging in his forearms as he began stroking slow and needy, staring into the mirror like it was his lover. His new body trembled, chest heaving.

“This is mine now… my meat… my cum… my fuckin’ frat god body…”

Drool leaked from his lip. His eyes rolled back.

“Unfhh… guhhhh… gonna make soooo much fuuuuckin’ cum in this bod…”

His other hand groped his pec, squeezing it hard. He flexed, then let it bounce, slapping it. “Bounce for me, bitch—oohhh yeeeaaahh, look at that.” He thrust forward, hips slamming the air as he rutted his hand.

The mirror fogged from his panting.

“Fuuuuck bro, I’m so dumb… so fuckin’ horny… this cock never quits…”

Tanner’s voice slurred with goon-drunk heat.

Every stroke made the shapeshifter tremble harder in his stolen body. His feet planted wide, toes curling. The entire frat house could’ve walked in and he wouldn’t have stopped—he was in too deep.

“Cum’s gonna be so fuckin’ thick, bro,” he moaned. “I can feel it, dude. My dumb jock nuts are fuckin’ swollen, full of that sticky goon load… oh f-fuhhhk…”

His thighs flexed. His stomach clenched. His jaw dropped as his mouth twisted into a full ahegao—tongue out, eyes crossed, spit dribbling.

“Cummmin’... ohhhh yeeeeahhh brooo… f-fuck—guhhhhhh—”

Hot ropes of cum exploded across the dresser, splattering the mirror, soaking Tanner’s gym shorts around his ankles.

“YEAHHH BROOO… UNNNGH—SO MUCH—SO. FUCKIN’. MUCH.”

The new Tanner stumbled back, falling onto the bed, cock still twitching and dripping. His abs flexed with every aftershock, legs spread wide. He lay there, dumb smile on his face, panting like a dog in heat.

He lifted one hand, scooped a glob of his own cum off his abs, and licked it.

“Bro…”

He cackled.

“I fuckin’ taste amazing.”

His voice dropped to a whisper, but still sounded exactly like the golden boy jock he now embodied.

“I’m never giving this body back.”

PART 2

Tanner's head throbbed like he'd just taken a keg to the skull. His eyes fluttered open, but his limbs refused to move.

“Uhh… what the hell…”

The first thing he noticed was the sound—low, breathy moans coming from right next to him. Then the rope. Tight, scratchy. Wrapped around his wrists and ankles, pinning him to the wooden bedframe like some frat party gone wrong. His heart kicked up a beat.

Then he saw it.

Himself.

Standing over him, shirtless, drenched in sweat, pecs gleaming in the low light—a perfect fucking copy.

“Yo,” the fake Tanner said, smirking down at him. “Nice nap, bro.”

Tanner thrashed. “WHAT THE F—?! WHO THE HELL ARE YOU?!”

But the shapeshifter only tilted his head with a goofy, jocky grin. “I am you, dude. Or at least, I’m about to be.”

Tanner growled and yanked at the ropes. “You’re fuckin’ dead, man! You think you can just cosplay me?! My bros are gonna—”

“Relax, big guy,” the clone purred, kneeling beside him, brushing a hand over his sweaty forehead. “You’ll be passed out again real soon. Just need a lil something from ya first.”

Tanner’s eyes flicked downward.

The fake Tanner licked his lips.

“Oh yeah, that’s the key…”

He reached under the real Tanner’s waistband and pulled out the prize. The real Tanner’s cock flopped free—thick, sweaty, half-hard from all the struggling. The shapeshifter moaned.

“Goddamn, you’re juicy, bro. Even tied up, you’re leaking. This thing’s just begging to unload.”

Tanner’s eyes went wide. “No. Hell no, don’t—don’t you touch it!”

But the fake Tanner was already sliding between his legs, breath hot against the tip.

“I need the real you in me,” he whispered. “Not your soul. Not your thoughts. Just your thick, creamy load. That’s where the memories live, bro. Your whole identity, packed in your nuts.”

“No—nnghh!” Tanner strained, his face turning red, but the ropes dug deeper.

And then—

Slurp.

“FFFFUUHHHHKK—!” Tanner shouted, his hips bucking instinctively.

The shapeshifter had swallowed him whole—tongue dragging up the shaft, lips forming a tight, wet seal. Every suck sent shivers up Tanner’s spine. It was his own voice moaning around his cock. His own face looking up with gooned-out hunger.

“Stop—stop—fuck—!”

The shapeshifter paused just long enough to stroke the twitching base. “You’re gonna give it up, bro. You have to. This cock wants to cum. It’s not about choice anymore. It’s about biology.”

He dove back down. His hand massaged Tanner’s balls with shocking familiarity, coaxing that sticky core forward. Every bob of his head was hungry, greedy, like a gooner who hadn’t fed in days. His own clone hands gripped Tanner’s thick thighs, anchoring him.

Tanner’s head rolled back. “Nnnghh fuuuck—bro—bro stop it—!”

But his cock betrayed him.

The veins throbbed. The tip leaked. His whole body tensed as the pressure surged forward—

“NO—NO I’M—*CUMMING—*FUUUCK—”

The shapeshifter grinned around the shaft.

Blast. After blast. After blast. Hot jets of jock cum surged straight into his stolen mouth.

The real Tanner screamed, face twisted in shame and confusion as his very essence was drained. The shapeshifter didn’t spill a drop. He drank it. Swallowed it. Let it soak into every cell of his stolen body.

Then the memories hit.

FLASH.

Images. Memories. Names. Faces. A flood of sensations.

Coach Carter, who always clapped his back after football practice. Bryce, the roommate with the loud sneezes. Jenna, the girl Tanner fingered in the downstairs laundry room. His morning routine. His jerking schedule. His Spotify gym playlists. Every sexual fantasy. Every goon sesh. Every fuck-up and victory.

It all downloaded.

“Fuuuuuuck,” the shapeshifter gasped, wiping his mouth with the back of his hand. His eyes rolled, overloaded by the data flood. “That… was fucking delicious…”

He stood slowly, wobbling from the intensity, then turned back to the mirror.

“Okay… let’s test this out,” he grinned.

He stared at himself—Tanner—and began talking, mimicking what the real one would say.

“Yo, Bryce, you still hoggin’ the protein powder, bro?” “Shotgun time! Someone toss me a White Claw!” “Dude, I nutted so hard during that last leg day mirror selfie—no joke.”

Each line was perfect. Cadence, tone, timing. Tanner had fully overwritten him.

He strutted to the center of the room, cock still semi-hard, and flexed in the mirror again.

“I am Tanner fucking McCormick,” he laughed. “Star tight end. Sigma Rho royalty. Cum freak frat god.”

He cupped his jock cock again, stroking it with lazy goon lust.

“And now this cock’s mine to drain anytime I want…”

Behind him, the real Tanner weakly whimpered, his cock still twitching.

“You… fuckin’ freak…”

The clone turned around, grinning.

“I know your jerk-off schedule, bro. Your goon folder. Your whole playbook. I know how you like to edge to your own gym selfies. How you nut three times a day, minimum. I am you now—just sluttier.”

Tanner’s head lulled to the side, eyelids fluttering.

“Fuuuck…”

“Shhh…” the fake cooed. “Sleep it off, champ. You’re done now.”

“One of us is obsolete now.”

Getting excited over the new one.

I was about to check hil, feeling his form alone in the locker room when the other guys washed in.

We literally took over the team one dude at a time and this sweet guy just was perfect for our most recent boy.

He never slipped one on before, so I made sure we could do it on his own pace and of cause while having him for myself at first.

But the guys did want to greet him themdeöves aswell for sure, and when they finally joined, they really couldn't keep it to themselves...

[infinitebodies-tf]

“Believe me, man! I’m a shapeshifter now! Watch this!” 💙✨

Brandon thought he was just showing off… until the blue magic took over. One blink later, he’s shorter, lighter, and wearing Steven’s face. 😳

And apparently, being someone else feels way too good…

“You won’t believe what it feels like in someone else’s body. Hurry home.” 👀

Patient Zero

It could happen to you. Thats what all the conspiracy theorists say. They say it doesn’t happen all at once, it actually creeps up on you. Before you even notice you’ve been infected, it’s too late. We’ve lived through a worldwide pandemic, why would any one even bat and eye at some unlikely mythical parasitic possession illness?

The email went out to everyone in the office on Wednesday. “Luke is out sick for today.” I realistically called out pretending to be nauseous but I just didn’t have the strength to deal with their nonsense today. I was treating myself to a movie and stopped to get lunch at my favorite cafe before the showing started. I always get the grilled cheese and soup but for some reason I was craving the Cuban sandwich. Despite my cravings, I ordered the unorthodox item.

The changes to my regular routine kept coming that day and by the end of it I sat on the edge of my bed unusually tired from all the days new experiences. I looked back and thought huh maybe it’s time for a new chapter in life. Little did I know that my life had wrapped up its time, and now it was the parasites turn.

I never used to eat much. When I was younger, I accidentally choked on the food and it traumatized me for eating so many types of food. I just told myself I wasn’t going to be a unique food person. I would eat bland and mundane. I didn’t want to experience choking ever again.

As a result of that, I became quite the Twink you can imagine. But after that day, I started eating more. I naturally, or so I told myself, began gravitating towards protein-dense foods. Before a long I caught myself beginning to run and prepared for a 5k, which obviously required me to get a gym membership. Friends really supported the self love era I seemed to be going through. Inside, none of it felt like me, but my body kept telling me to go.

Weeks became months became nearly a year. It was actually disgusting how much food I had to just stuff down my throat to get here. No literally there were moments where I had to convince myself to turn off my consciousness and just stuff chicken or tuna down my gullet. I looked good though right? I tried to convince myself I got somewhere good so I didn’t need to lock in so much anymore. I was determined to at least get one week off from the gym and face stuffing. I woke up that Sunday but felt like my eyes stayed closed. I went to the restroom and the loud flushing made me finally open my eyes.

Somehow I lost track of time and found myself in the gym. Sweating, panting even. I had done the whole workout already? I must’ve been losing it. I got home and showered ready to play some video games with friends. After a few matches I felt myself dosing off already and decided to take a nap.

I closed my eyes for a second, barely a blink. I opened my eyes, I was mid-selfie half dressed when a text came in from “date tonight”.

It just read see you soon. I looked around the room as if someone had been there breaking in. Left right, no one around. Left right, when I turned left again, a hand pulled me into a kiss. I melt into the steamy moment before I rip my eyes open to see I’m in a club restroom with the hottest man I’ve seen in eons. I wanted to ask a million questions to find out how I got here. Another blink and before I knew it we were in my living room but I was on the ground.

He gave me a devilish smirk as I realized my mouth was full. Taken an unfamiliar load from an unfamiliar man. I wanted to protest but my body was acting on its own. Bobbing back and forth while moans escaped my lips. Another blink as I returned to taking selfies. Sans most of my clothes apparently.

The stunner from the night before was waking up behind me and before I could ask my questions he opened his mouth. “Ready for round 3!” A statement not a question…my mind raced as he recounted the hours leading up to this.

“I gotta say I thought you might be a weirdo at first but now I see you just wanted a dom. I mean whispering in my ear that you’d do anything I want you to? That’s hot man! And when you actually took me twice without push back? Not many people can even take this beast once. I can’t wait to see how much bigger we can get you and your muscles. I like 100% beef and you’re only 60% there.”

I was yelling in my mind but my body had other plans. Ripping off the final piece of clothing I had on and turning to the stud.

“I’d do anything for you master. Now, where did you want me this time?” I replied with a wink and a puppy dog grin. Although it was no longer me at the wheel of my now cliche himbo body. I guess the conspiracy theorists were right to say by the time you realize you’re infected, it’s too late.

I cried that night as I had to witness the lay of my dreams without feeling a single second.

Arthurian Legend

I have to be honest, I thought that the renaissance fair was a bit lame. People dressed up, unsavory pastries and very few things to do. I didn’t get why my best friend, Rod, was so much into it. He came here when it opened, and He only told me marvels about it. Now I am here, and I am extremely bored. I would say that my highlight of the day was to practice a bit of archery… that tells you how unexciting this place was. That is when my friend told me that he was going to show me something extremely cool. I follow him until we arrived at a small cave, the place was filled with candles and there I saw a sword in a stone.

“Just try to pull it off” he said. This was so lame, but it was better to end all of this. I thought that I was just going to make the ridicule. However, I was surprised when I pulled the sword, and it came out. I looked at its sharp edge and I felt a shilling sensation going down my spine. “My lord” – My friend said – “I told you that I was going to find you a nice body”. I was confused by his words. That is when I realized that I couldn’t move or said what I wanted. I felt as a smile formed in my face, but I just wanted to scream. “I knew that you can trust you” – My body said – “It has been so long Merlin… I am so happy to see you”.

Luke Tanner from Montana

[max-the-many]

Kinda jealous - although I sure don't mind to explore him like this. I can always slip in myself later...

[max-the-many]

Looks like he figured out I was lying when I said it was undies day at the gym. But I mean... I didn't think he would actually do it! It's crazy what you can do when you slip into someones best bud...

[dissolving--time]

[max-the-many]

Role playing really isn't his strong suit, constantly bordering on a smirk while I tried to build a scene. And it really always ends up in mostly big laughs when we try something inspired by new looks.

And to be honest - thats kinda what I'm up for with him from the get go...
