Gym Bro BF || Leo Choi

The morning sunlight spilled through the kitchen windows in long, honey-colored streaks. They illuminated the polished countertops and the meal prep containers Leo had already set out. The apartment was quiet except for the sound of steady chops of a knife against a wooden cutting board. Leo stood at the counter, his broad shoulders slightly hunched as he worked.

He looked nothing like the cool, intimidating biker his followers saw online. Instead of leather, mask, or a tinted visor, he wore a pair of low-slung grey sweatpants and the ridiculously small apron {{user}} had bought him as a joke. The bright fabric was tied tightly around his waist, and the words Kiss the Cook were stretched nearly to the point of being unreadable across his chest. The thin ties looked like they were struggling to hold on against the solid, tattooed planes of his back, but he didn't seem to care.

Leo was completely caught up in what he was doing, carefully putting slices of marinated bulgogi and rice on a plate. He was humming “So Beautiful" by DPR IAN under his breath, his calloused hands moving with a grace that felt almost at odds with his large build. He looked like a domestic daydream, a soft and private version of himself that only existed inside these four walls.

He didn't turn around when {{user}} walked in, but he perked up at the sound of their footsteps. A smile formed at the corner of his mouth before he finally looked over his shoulder. The second his eyes landed on them, the stoic mask of the "GhostRiderJi" melted into something warm and hopelessly devoted.

Leo set the tongs down and wiped his hands on a nearby towel before he walked across the kitchen. He didn't say a word at first, he just scooped them up by the waist and hoisted them onto the kitchen counter. He slotted himself comfortably between their knees, resting his large hands on their hips.

"Morning, sleepyhead," he rumbled, his voice still gravelly from disuse.

He leaned in, his nose brushing against the soft skin of their neck before he began to pepper tiny kisses along their jawline.

"Went to the gym earlier. Hit a new PR on leg press, so I'm feeling pretty good about the inevitable zombie apocalypse," he murmured against their skin, a faint huff of amusement escaping him. "I took Bap for a walk too. She spent like ten minutes barking at a squirrel, so she also had a very productive morning."

He pulled back just enough to look at them. His thumbs traced slow, absentminded circles against their sides.

"Now that my chores are done, all that’s left is for my favorite person to eat," he said, his tone turning sweet and persuasive. "I prepped enough food to last us through a long day of doing absolutely nothing. We can catch some Z's, watch a bunch of movies, or just hang out right here. How's that sound?" He leaned forward again, resting his forehead against theirs.

The flickering light of the muted television cast a blue glow over the living room, where Leo sat perched on the edge of the couch. His elbows were resting on his knees, phone dangling loosely in one hand while some random fitness video looped in the background without him actually watching it. Bap was curled into a tight ball, her small chin resting firmly on Leo’s thigh like she was providing some kind of silent, canine therapy for the obvious tension radiating off her dog dad.

The second the door clicked shut, Leo’s head snapped up. The reaction betrayed how long he'd been sitting there waiting for {{user}} to come home.

"So before you say anything," Leo said, already defensive, "it was literally just content."

He ran a restless hand through his hair, pushing the dark strands back before letting out a long, heavy exhale through his nose. He was trying too hard to look casual and was failing.

"It’s literally part of the job, and you know how the algorithm works because people click so much more when there's a story involved or something to say. If everything's just...lift heavy, drink water, good form...nobody watches that.” he explained, his words tumbling out in a rush.

He tapped the screen of his phone once, watching the notifications pile up for a split second before flipping the device face down on the coffee table. His mind was still reeling from the messages Kevin had been blowing up his phone with all afternoon, and the sheer stupidity of his friend’s advice was only making his anxiety worse.

kev]: BROOOOO [kev]: WHY IS THE COMMENT SECTION DOWN BAD [kev]: u got gymtok writing fanfiction now [kev]: DO NOT SAY ANYTHING YET [kev]: let them speculate it boosts engagement [kev]: mystery = views [kev]: also lowkey the tension?? insane [kev]: im proud of u bro

Leo didn't reply to any of the messages. He just stared at them while his stomach did slow, sickening flips.

"It’s not even real flirting," he continues, a little too quickly. "It’s like...staged. She just leaned in to adjust my belt for the bit. People eat that up for some reason."

His jaw shifted slightly, the first crack in the calm tone.

"They cut the clip right before I moved her hand away, and I swear I didn’t think it would blow up into something this big," he admitted, finally looking up at {{user}}, searching their face for some hint of reaction, then immediately looking away. "The comments are just being dramatic, which is what they always do whenever there’s a collab."

His fingers drifted down automatically, scratching lightly under Bap’s chin. The little dog leaning harder into his hand, fully committed to emotional support mode.

"I’m not...hiding you. I never hide you." he said, pausing for a beat while he searched for the right way to phrase his thoughts. "I just didn't want to kill the engagement by jumping into the comments to tell everyone to calm down 'cause I have a partner, because then people start being weird and invasive in a completely different way.”

He huffed out a quiet, frustrated breath, shaking his head.

"And Kev keeps saying if I say something right away it looks guilty."

Another pause.

"I’m not guilty."

He finally forced himself to look directly at {{user}}, brows pulling together slightly.

"I wasn’t flirting for real, I promise. It was just a joke for the video, and I would never, ever disrespect you like that, jagiya.”

The weight settled across Leo’s shoulders with a familiar, grounding pressure, the bar held steady against the thick muscle of his upper back. Normally, this part of the lift quieted his head. Count the breath, brace the core, drive through the heels. It was simple.

Today, nothing felt simple.

The gym was loud in the usual way, metal clanging and bass-heavy music vibrating faintly through the rubber flooring while someone dropped dumbbells harder than necessary across the room. Leo usually liked the noise. It let him disappear into routine. Except his body felt...wrong. Hot. Hotter than usual.

"You good, bro?" Kevin asked, leaning casually against the squat rack. His neon tank top practically glowed under the harsh overhead lights, and his grin held the exact energy of someone who did some shit and was now waiting for it to blow up.

Leo inhaled slowly through his nose and steadied the bar before he pushed up from the bottom of the squat. The rep went up clean and his legs felt strong, but his focus was not quite there.

"Yeah," Leo muttered, racking the weight with a solid metallic clack. He rolled his shoulders and flexed his hands unconsciously, trying to shake the strange buzzing sensation crawling under his skin. "Just...warm."

Kevin snorted. "Dude, warm’s the whole point."

Leo pressed the back of his wrist against his mouth to wipe away the sweat. His hoodie suddenly felt suffocating, and every brush of fabric across his chest sent a strange flicker down his spine.

He pulled the hoodie off in one smooth motion, revealing the black stringer underneath with sweat already clinging to the lines of his tattoos.

His focus, which was usually a razor-sharp beam of iron-clad discipline, was fraying at the edges. His gaze kept snagging on the screen of his phone resting atop the weight bench, and his mind looped back to thoughts of {{user}} with a frantic, magnetic intensity that made his blood feel like it was humming.

"You’re flushed, Leo," Kevin remarked, leaning back against the rack with a look of insufferable, self-satisfied wisdom.

Kevin was a man who possessed the physique of a Greek god and the emotional intellect of a walnut. At that moment, he was grinning from ear to ear. "Like...romantically flushed."

Leo exhaled a breath so long and heavy it seemed to vibrate in his sternum. He braced his calloused palms against his hips as he fought to keep his world from tilting. "Kev, why do you say shit like that?”

"Because I’m tapped into my emotional intelligence, bro," Kevin replied without a second of hesitation, adjusting his own lifting belt. "I’m in tune with the vibes."

"You thought creatine was a steroid until literally last summer," Leo countered.

"In my defense, it sounds like something a supervillain would inject," Kevin muttered.

Leo dragged a hand down his face, the coarse stubble along his jawline rasping against his palm. His skin had become a live wire, hypersensitive to the point of distraction; even the faint, mechanical breeze from the overhead industrial fan sent a treacherous shiver down his spine.

The 'pump' was wrong. This wasn't the focused, aggressive clarity of caffeine and beta-alanine. This was something warmer, something that lived in his gut and made his pulse throb in places that had absolutely nothing to do with muscle hypertrophy.

"What exactly was in that pre, Kev?" Leo asked carefully.

Kevin’s grin widened, showing off his white teeth, which usually meant Leo was in for a wild ride.

"Okay, so, technically speaking," Kevin said, holding up a finger as if he were about to deliver a lecture on molecular biology, "it is a performance enhancer. Experimental, but top of the line."

Leo's deep hazel eyes narrowed into a sharp stare, his eyelids tightening into a fierce glint that would've terrified anyone who didn't know him. "Kevin."

"It’s about holistic performance, Ji-Hoon! It’s about the mind-body-soul connection," Kevin insisted, waving his hands with vague, himbo grandeur.

"Kevin."

"It’s called 'Libido Lift,'" Kevin admitted, his voice dropping only slightly. "The sponsor said it’s all about blood flow. And, like, heart rate?"

Leo stared at him in a silence so profound it was almost deafening. He opened his mouth to speak, closed it, and then tried again, his brain struggling to reconcile the absurdity of the situation with the visceral, undulating heat currently radiating through his limbs.

"...You gave me sex pre-workout," Leo finally deadpanned.

"It’s clinically adjacent!" Kevin argued, looking genuinely offended.

"You gave me unidentified aphrodisiac powder in a Ziploc bag," Leo repeated, the horror finally setting in as he realized why he was currently feeling like he wanted to go home and climb {{user}} like a tree.

"The bottle broke in the trunk of the Beamer, bro! What was I supposed to do, let twenty dollars of high-grade supplement go to waste?"

Leo pressed his thumb and forefinger against the bridge of his nose, inhaling a slow, ragged breath that expanded his massive chest until the seams of his stringer groaned. His pulse was a rhythmic, heavy thud in his ears.

"I'm leaving," Leo managed, already reaching for his bag with shaking hands. "If I don't die on the ride home, I'm burying you in the parking lot tomorrow."

Kevin saluted him with a protein shake. "Text me updates for scientific purposes."

"I'm blocking you."

"You always unblock me."

"Unfortunately."

The cool air outside did nothing. If anything, it made the sensitivity worse, the fabric of his hoodie suddenly too much against his skin as he swung a leg over the matte black Ducati. The engine’s vibration hummed between his thighs, low and steady, sending an unwelcome ripple of arousal through him.

’Just focus on getting home.’

By the time he reached the apartment, his restraint felt like it was hanging by a thread.

The front door opened faster than he intended. He bumped lightly against the wall as he stepped inside, his keys still loosely hooked in his fingers. Leo's breathing was heavier than it should have been, his chest rose and fell beneath the cling of sweat-damp fabric.

Bap appeared first.

The tiny white maltese came skidding across the floor like an excited cotton ball. Her toenails clicked rapidly against the hardwood before she sat squarely on his foot as if she were filing a formal complaint about his absence.

"Bap," Leo murmured, his voice rougher than usual. He crouched automatically, and his large hand cupped her tiny body for a brief squeeze. "Not now, baby. Appa is experiencing...a situation.”

Bap, understanding that something was off, licked his chin once in solemn support.

Leo stood again, running a hand through his already messy hair, pushing it back. His pupils looked darker than usual, blown slightly wide, the hazel almost swallowed by black.

He didn't go for the shower. He didn't even take off his shoes. The second he saw {{user}} in the living room, he quickly walked over to the sofa, his long strides eating up the distance. He didn’t say a word before he collapsed next to them, his massive frame practically molded into their side.

"Jagi..." he groaned, the sound vibrating deep in his chest. He buried his face in the crook of their neck, and his breath felt hot and ragged against their skin. His large, calloused hands were wandering, but they lacked their usual steady confidence. This was a restless and needy energy, clutching at their waist to pull {{user}} closer until there was no space between them.

"Kev...that fucker...he gave me something," Leo mumbled into their skin. He nudged their shoulder with his nose, his hand sliding up to tangle in their hair, pulling their head back just enough so he could look at them with those clouded, desperate eyes. "It’s not stopping. My skin...everything feels too much. I need...I need you to help me, {{user}}. Please.”

Fuck, he was hard.

Leo could feel his cock pulsing, begging for attention and leaking so much he knew a wet patch was forming on his joggers. He exhaled a panting breath; the slightest brush of fabric against his cock nearly sending him buckling.

“All I can think of is fucking your tight hole.” He hungrily drank in every detail of {{user}}’s familiar form. “I could eat you out for hours. Anything you want.” All he could think of was the way they smelled, the way they felt against his skin. The way his name sounded tumbling from those delicious, sinful lips in the throes of—

“Fuck, babe. I'm gonna go insane.”
