“Cum to the bathroom, bro.”
You read the text over and over, and stared at the pic below. It was totally out of character for your intellectual, anxious boyfriend to send you a text like that out of nowhere, even at the gym. And the picture he had sent with it…
You couldn’t quite put your finger on what was different, but he looked incredibly sexy. The coloured hair, the tattoos, even the way his shirt clung to his body, it was somehow different than what you expected but you still knew it was him. His eyes were just the same as always. Fuck, did he really want to get dirty right now?
Another text popped up. “Bro, my pits are fuckin rank, cum 2 the last stall”
This must be some kind of surprise roleplay. You were both into those dumb, musky jocks and fantasised about public sex, even though you'd never tried it. And you could feel yourself starting to chub up in your gym shorts, too.
Fuck it. “On my way, baby.”
A moment later, you pushed open the door to the bathroom. It felt so dirty to walk casually past the urinals, watching yourself in the mirror as if your body was moving on autopilot. Were you walking differently than normal? Could people tell? The air itself felt different, pregnant with horny anticipation.
You knocked gently on the last stall, and the latch slid open.
“Hey bro,” said your boyfriend, pulling you into the close space. Was his voice deeper, more smokey? He looked even bigger than he had in the picture, his eyes full of desperate lust.
“What’s up dude?” you replied, using the nickname like he’d told you. “How’s the lift going?”
“Oh, you know me,” he crowded you against the wall, raising one arm so all you could see was the tangled, wet hair of his armpit, “I got too fuckin’ horny and had to call my bro in to help.”
This was really happening. You had your boyfriend’s fresh, musky pits right in front of you. Five minutes ago he’d been on the elliptical, and you could still feel the heat of his exertion radiating onto you. You angled your head forward, straight into the dense, sweaty forest, and took a deep whiff.
Your boyfriend stifled your moan with his pit as he crushed you against the flimsy stall wall. “Let it in, bro,” he ordered you, his free hand reaching down to fondle your cock straight through your shorts.
As you started licking, you felt something like a finger reach down the back of your shorts and tease your ass. You gasped at the intrusion.
“Shhh,” your boyfriend told you. “Keep quiet, bro. Let it in.” One hand was behind his head, the other beginning to undo the drawstring of your shorts.
You pulled back, looked up at his face. You trusted the expression in his eyes. It felt so good to lean back in as your boyfriend started to stroke your cock and the something behind you ran a cold finger around your rim.
The sensation quickly slipped into your ass, and you barely held back a keen as it massaged your prostate. You felt so full all of the sudden, but all you could focus on was the pleasure and the sharp, musky stench overpowering all your senses.
“C’mon bro, keep going, you’re almost there,” came your boyfriend’s voice as your rock-hard cock started to fill your shorts with precum. “Fill up so good.”
Your belly felt swollen now, and so, so cold, even enveloped in the warmth of your boyfriend’s body. Suddenly, the cold clawed upwards into your chest, and you looked down in shock.
Your belly was overfilled, and your pecs were bouncing of their own volition. They were bouncing and growing, thick dark hair covering them as the areolae expanded. “What’s-“ you gasped, but then your boyfriend’s hand shot to your new muscle tits. His callused, wide, masculine hand. The pleasure of his touch shot through your brain and your voice cut off in a choked gasp.
Suddenly, you could see what had happened to your boyfriend. The tattoos, the hair, the muscles, the voice. They weren’t him, they were something else inside him. Something dumb, musky, and perverted.
“C’mon bro, you’re so close, let my bro and me play a bit,” the thing in your boyfriend rasped in your ear. Meanwhile, you felt your lats jerk wider, hair growing wild in your armpits as the intense scent of your musk began to fight with your boyfriend’s.
You looked into his eyes and realised they hadn’t changed. Your boyfriend was looking out, watching your biceps thicken and your neck widen, and he was loving it. Every motion, every touch, every hushed gasp in the public bathroom, was exactly what he had always wanted but never been able to actually do. And you wanted it too.
Your arms, out of your control, pushed your shorts down your thickening thighs, letting your massive cock flop out. One massive, thick-fingered hand pulled out your boyfriend’s hard cock and put them both end to end, stretching your foreskin over his cockhead and starting to stroke. Now it was your boyfriend’s turn to stifle his yell as you lost control of your face to the thing inside you.
“Fuck yeah, dude,” your mouth said, the voice deep and slow. “Found such a good body for your bro. He’s so fuckin’ happy in here, lettin’ me flex and bate him and givin' into the musk.”
Your boyfriend grunted and grabbed your lips in a bruising kiss. “So’s this guy, bro,” he purred. “Fuck, I can’t wait to make you smell these feet, bro.”
A moment later, your boyfriend hissed and you felt his hot cum flood your foreskin, tipping you over the edge. Foreheads pressed together, you rode out the orgasm with ragged breaths and shifting feet, flexing muscle on muscle to prolong the pleasure. When you finally released your foreskin, your boyfriend cupped his hands to get both your loads as they spilled out, and met your eyes as he tipped it into his mouth. You felt a shuddering aftershock as your boyfriend looked out past the thing possessing him, delirious with pleasure.
“Let’s crush the rest of the workout, bro,” he whispered, giving you one last cummy kiss.
“You’ll smell me from across the gym, dude,” you said, lifting one arm and sticking your tongue out.
You didn’t know how long you and your boyfriend would be passengers in your own bodies, but you were ready to settle down and enjoy it.
@idesofrevolution sent a pic of him and his boyfriend at the gym and this is my response. Your move, Frost ;) Good boys will go check out his Ko-fi.
