Jon twisted back and forth under the showerhead, singing along to the music blasting from his phone on the counter.

The music lowered in volume for a second, making way for two loud dings. Jon reached out from the stream of water and fumbled with the screen in his wet hands. It was a message from Oliver, his best friend, “Hey bro, got something you should listen to.”

“Bro?” Jon wondered. Since when did Oliver say “bro”? Jon blinked, struggling to think for a moment. Oliver talked like that all the time, he was American after all... wasn’t he?

Attached to the message was an audio file. Jon figured it must have been a new song by one of the pair’s favorite pop divas, perhaps a new leaked track. Jon hit the play button, placed the phone back down, and returned to the hot water.

A harsh static buzz and what sounded like garbled speech boomed from the phone, taking Jon by surprise. The corrupted audio cleared up after a moment and a deep, male voice started.

“Welcome. This audio program is custom designed. Just for you. Ensure you are in a comfortable, private place. You will not want to be disturbed.”

“Oliver,” Jon rolled his eyes, thinking that surely something starting this ridiculous would be some sort of joke or meme. After all, Oliver had always been a dumb joker. “Wait,” Jon felt confused, he could have sworn Oliver was a quiet, twinky lad like himself?

Jon realized couldn’t form a solid impression of his friend in his mind. They met at their university in London and became best friends, bonding over their mutual love of pop music and ogling the campus jocks. But now it was like that reality had been shattered. Those memories gave way for ones of meeting each other at the campus gym shortly after Oliver arrived from the US. Oliver was his best, hot, American friend, right? Jon’s cock twitched at the new image of his friend as he placed his face under the stream of hot water in an attempt to clear his head.

“Relax. Take a deep breath, in and out.”

Jon unwittingly followed the instructions. The frown fell from his face and his body relaxed, taking in the warmth of the water.

“You’re Oliver's best friend. Makes sense, given you’re a total alpha too.”

“Both wha- ah! Ah!”, Jon planted his hands against the wet, tiled wall as the words sent pleasure rippling through his body. He looked down feeling a strong warmth against his leg but it wasn’t the hot water. His semi-hard cock had blasted a rope of cum against his leg. “What the fuck?” Jon mumbled.

“What a coincidence that you’re both six-foot-four. It serves him well in the gym, the same way it serves you well in the water.”

Jon howled in ecstasy, spluttering and moaning, as his five-foot-nine body stretched higher. His soft cock drooled hot cum as it rapidly began to rise. His arms pushed against the wall, lengthening for better performance in the pool. He stepped backward as his head struck the showerhead and rose even higher. Hot water poured down the front of his much longer torso and legs.

“Your shoulders are so broad. Typical of you swimming jocks.”

Unable to resist the command, Jon's shoulders crunched and throbbed, thrusting out larger and bulging with muscle. “God! W- What the fuck i- is... ugh... happening?!” he roared, terrified not just by the growth gripping his body, but the incredible pleasure it wrought on him.

“Those are some long, meaty fucking arms, Jon.”

“F- fuck!” Jon roared, spraying a massive load up the back of the shower feeling his narrow arms explode with thick mounds of muscle, rippling across his biceps and triceps. The growth spread down his arms, his forearms bloating with tight, lean muscle. His wrists cracked as they thickened.

“Hands that big must be useful for pushing through the water.”

Stifled screams rumbled from Jon’s tightly clenched mouth. His hands were pressed against the back of the shower, clicking and twitching as they began to swell across the tiles. The fingers accelerated longer and longer. His palms spread monstrously broad. He flexed his hands, in total awe of their disproportionate size; perfect for pushing through the water.

The experience was like nothing Jon ever felt. A sexual eruption taking place across every cell as the words rewrote his body. “Can’t... resist... so g- good,” Jon grunted, gasping for air.

“You clearly work out for the aesthetics as well, not just the pool. Your shredded chest is proof of that.”

Jon couldn’t even attempt to fight anymore, but nor did he want to. His chest puffed and bulged, distorting the path of the water running across it. The previously non-existent pecs pushed outward from his widening chest. His cock trembled as the changes took hold in his abdomen, causing his flat stomach to erupt with tight, thick abs. Jon gripped his ass, feeling it swell into his huge hands while he erupted cum across the tiles once more.

*“That’s the spirit, Jon. You’re a *stud.”

Jon felt those words echo in his ears and rumble down his throat. Grunts and pants became deeper and deeper as his thickened and voice morphed. His head groaned as it enlarged to fit his frame. Hair began to flourish out of his cheeks and across his upper lip while the mop of medium-length hair on his head retreated, leaving a short, handsome cut in its place. He stroked his cock with one hand and clasped his face with the other feeling his jawline refine and the angles of his face sharpen. He turned to the mirror cabinet, seeing just a sliver of his improved visage. Jon gasped at the sight and immediately ejected another load of cum.

He didn’t just look like a swole swimming jock. He felt like one too. He rejoiced in his mind being filled with thoughts of the pool, weightlifting, spotting his bros at the gym, and fucking them afterward.

“Good to see the bottom half matches the top.”

Jon’s legs trembled. He clutched the slippery tiles harder to hold himself up, the pleasure reverberating through his legs almost too much to bear. Muscles spasmed in his calves, swelling with every little twitch. Muscle wasn’t all that was gracing his legs. Dark hair grew forth from the skin, coating his powerful legs in a layer of fur. Jon swore under his breath, impressed by the hair spreading up and down his legs. He thought about how he refused to shave like other swimmers, he liked the hair, and regardless his superior form needed no extra boost. His body responded to the suggestion, triggering a fine layer of hair to sprout from his forearms, between his pecs, in a trail over his abs and across the tops of his feet.

Memories of the pool, the beach, and victories across university swimming tournaments swarmed his brain. Trophies and medals materialized in the bedroom just next to where he was showering.

“Damn, it’s no surprise you outperform everyone in the water with feet that massive. And you know what they say about that, Jon.”

Every one of the toes on Jon’s size eight feet surged with pleasure. He moaned loudly as they began to push across the floor of the shower while his soles stretched to catch up. He recalled new memories of having large feet, how they propelled him to victory in the pool, and the comments people would make: “Bigfoot”, “You know what they say...”, “Where can you even buy size sixteens?”

“Sixteen?!” he repeated in his mind. The brief shock turned to anticipation as he felt his soles continue to march forward longer and wider, his toes twitching while they reshaped long and meaty. Jon growled aloud as he expelled another load, “God, yeah... so f- fucking... big.”

The jock trembled under the stream of hot water, desperate for sexual release. He looked down as the expanding feet settled into excessively large size sixteens, curling his long toes as his six-inch cock began to quiver in its desperation to grow larger as well. It felt as though it were perpetually hardening, only to then push longer and girthier instead. Jon grasped his wet cock and thrust into his grip hard and repeatedly. He relished in the sensation of the veins bulging and the shaft thickening.

*“I guess what they say really is true, isn’t *it?”

The audio toyed with him, pushing his cock just that little bit longer and pumping it ever so slightly thicker. It pulsed and twitched, gradually and slowly with every breath. His uncut, British foreskin slid further backward, as a larger, blunter head swelled outward. Jon smirked as he groaned and growled, stroking faster and faster, enthralled by the beautiful nine-inch weapon he now possessed.

“Cum.”

“Oh yeah! Fuck, fuck, fuck!” Jon made three final long, hard tugs on his thick pole before roaring in delight as unspeakable ecstasy filled him. Cum rocketed upward against the water rushing from the showerhead, ejecting what remained of Jon’s old genetic material while orgasm after orgasm pounded his body.

Exhausted and dripping wet, he stepped slowly out of the tub, unsteady on his new legs and feet.

*“Remember to share this recording with your friends*.”

And with that, the playback stopped. Jon looked at himself in the mirror, still shocked, but enraptured with his new body and looks. He grabbed his phone and wiped the water from the screen, struggling to unlock it with his longer fingers. He typed out a reply to Oliver, “That shit was fucking lit mate!”

A few miles away, a sweaty Oliver was busy lifting weights, waiting for his friend to give him some indication that something had happened. He had to place the weight down slowly as his mind blurred for a moment. He saw the images and memories that he had of his friend change and shift. Gone were the images of a quiet little twink, replaced by those of a loud, masculine swimming jock. Oliver smiled cockily realizing what had just happened. Then, as if on cue, his phone vibrated with Jon’s reply. Following was a photo of a huge, semi-hard cock swinging above two gargantuan feet. Oliver felt his own cock stiffen slightly at the image.

“Hell yeah, bro! You should be selling these pics like I do,” Oliver sent in response, getting a deep chuckle out of Jon.

Both men now looked at their phones, horny and pondering who next to share the mysterious audio file with.
