Figuring out the ins and outs of a new gym isn’t easy but it isn’t impossible. Go too early and you’re surrounded by creepy men old enough to be your grandfather. Right after work is a sure way to experience hoards of gym bros crowding around machines like they own them.

So you go as late as possible.

Only a handful of people are dispersed through the large space. A few run on the treadmills lined on the catwalk of the second floor, several switch through different weights in front of the mirrors. You make your way through the maze of equipment towards the leg press; your final sets before you can go home and wash away the grime of the day.

Or you would if someone wasn’t occupying the one machine you need.

Peeping your head around, you notice a black backpack and matching water bottle on the ground. You glance around, unable to find a clear owner since the next closest person is halfway across the gym doing a different exercise.

Would it be that rude to take the machine out from under someone if they’re not even using it? You could probably get in all your sets before the person even came back if you moved quickly.

You wait a few minutes. How embarrassing would it be to have the mystery person walk back up the second you sat down? But after five minutes pass and no one emerges to claim the spot, you set about changing the weights out.

And just when you slip into the seat, you look up and find someone approaching.

He’s tall, he’s handsome, and he’s barely ten feet away. Your saving grace is that he hasn’t spotted you yet thanks to his phone.

But that doesn’t last long.

“Oh! Sorry! Were you using this machine?” You ask, trying to sound cordial.

“It’s okay!” He smiles at you. “Do you need it?”

Yes.

“No, I can find something else to do.”

You rise to do just that when he stops you with a shrug.

“I don’t mind sharing.”

“Are you sure?”

“Yeah, I take long breaks between my sets anyway so it’s no big deal.”

So that’s where he went.

“Okay, thanks.”

“No problem.”

He moves to lean against the wall, face buried in his phone once again as you work through your set. Honestly you think he forgot you were even there until you start standing up and he pushes off his perch.

Exchanging polite smiles, you skirt around him and snag your water bottle before occupying the same spot against the painted bricks. You try not to be a creep but watching the way the muscles in his legs bulge and coil with each rep is impossible to look away from. Especially when there’s just so much to look at.

He racks up twelve reps with ease and switches back off with you before wandering out of sight.

You work through two of your sets before he comes teetering back.

“I tried putting it back to your weight.” You laugh, sipping from your water bottle.

“Three forty? Ouch.”

“What? Should I have made it lighter?”

“Try heavier. Like four hundred.”

“My sincerest apologies.” You mock, placing your hand over your heart. “I’ll remember that next time.”

He laughs again before slipping back into the seat and working through the motions.

This time you don’t bother hiding the way you watch him over your phone. He looks good, it’d be a waste not to watch the swell of his chest or the stretch of his thighs. The gym shorts and snug black t-shirt only exacerbate how cut his physique is.

And if he makes a comment you can always twist your not so subtle gawking into a compliment about his form.

When he finishes his set again, he snags his bag and water bottle off the ground before turning to you. “All yours. Have a good night.”

“Yeah, you too.”

And he’s gone.

Over the next few weeks, you learn mystery man works out at the same time you. He’s there when you arrive and remains when you leave after an hour and a half of sweating and gasping like a dying fish, only absent on Wednesdays when you manage the most last luster workouts of your life. The disappointment the first time you realized you were looking for the backwards cap sticking out amongst the free weights would have been embarrassing but what's wrong with a little eye candy while breaking a sweat?

And what a great view he makes. Your brief peeks into the mirrored walls are full of nothing straining muscles and glowing skin. The first day he did arms in a cutoff tee will go down in history as the worst day of your life. Only rivaled by all the other days he works his legs in shorts accentuating just how nice his ass is with every squat.

Your friends all ask when you’re going to talk to him again. As if you’ll just walk right up and interrupt the best part of your day. No, you’d rather watch him move across the gym floor from the corner of your eye, throw him a friendly nod, and go about your business than run the risk of making things awkward.

Unfortunately, doesn’t possess the same desire to remain a friendly nameless face like you do.

His name is Mingyu. Or that’s what the employee with glasses calls him while they joke around one night. You don’t mean to eavesdrop but they’re loud and the only exit takes you right past the U-shaped desk. Mingyu throws a grin as you pass by on your way out and the flash of teeth spikes your heart rate higher than any exercise you’ve done that night.

When he officially introduces himself at the water fountain the next night, you have to bite the urge to tell him ‘I know.’ Instead you snort at his extended hand, providing your own name over the firm shake like you won’t be haunted by the feeling of the calluses on his fingers or the heat of his palm for the next week.

What’s worse is how he says your name back, rolling the sound across his tongue and past his quirked lips.

And the final nail in the coffin is when you leave and you see the way he turns in the glass doors to watch, bidding you a goodnight with your name signed at the end.

Mingyu might be the worst gym crush in the world. Mostly because your thoughts of him extend beyond the brick walls he should only exist in. And partially because he’s caught you staring more times than you care to admit.

Not as many times as you’ve caught him, but the point stands.

No, the worst part, you find out, is Mingyu is an incorrigible flirt. And he knows it.

Tonight you’re off schedule, runny nearly half an hour later than usual.; work clothes sticking to your skin as you make your way towards the off shooting hall housing the entrance to the locker rooms. In a rush, you step around another body only to end up in front of one much more familiar.

“There's my girl.” Mingyu smiles. “Thought you were skipping out on me.”

My girl. My girl. My girl, my girl, my girl….

There isn’t a thought in your head beyond the bold casualness he drops that bomb on you with so you nod awkwardly and force yourself not to sprint the next twenty feet to hide.

Half an hour later, when you catch him watching you in the mirror over his own weights, the bastard smiles like the cat who caught the canary.

But you end up on top when Mingyu offers to spot you while doing weighted squats. He’s at your back, an appropriate amount of space between your bodies you wish he’d close. You don’t need his help. Your form is better than his (you would know, his ass and thighs give you tunnel vision when its his leg day). And the weight on the bar isn’t even enough to make you strain but why pass up on the offer? Especially with how Mingyu meets your eyes over your shoulder in the mirror with each dip.

And then he cheers ‘that’s my girl’ again when you re-rack the equipment with ease and it's over.

“Shit,” you grunt.

Mingyu pops up from his perch between your breasts under your shirt, hair a mess and eyes glazed. “Good?”

“No, your steering wheel is in my back.” You wince, attempting to wiggle away and ending up further up his lap.

“Sorry, let me just…”

The seat flies back under your combined weight, throwing your forehead right into Mingyu’s chin.

“Fuck!”

“Oh my god!” You gasp. “Are you okay?”

Mingyu’s head falls back as he releases a massive sigh. Each second that ticks by has you both coming to the same conclusion.

“Yeah,” you breath, sitting up. “I think this was a bad idea.”

“Oh…”

“I just mean like your car is small and you’re too big and I—“

The guffaw Mingyu tries to hide slips free too easily. “That’s what she said.”

“God, you’re gross.”

Your nose crinkles as you rise up, using his chest for leverage. It feels as nice as it looks and its the worst knowledge you’ve gained in you life.

“Sticks and stones,” he hums.

“Well this was fun. I’ll ugh… see you around?”

When you try to shift back into the passenger seat to exit, Mingyu’s hands flex over your thighs to keep you in his lap. His sweats do nothing to hide his semi. Something he doesn’t even seem to consider as a concern given the way he unconsciously curls into you.

“Or we can go back to mine.”

He’s trying and failing to sound nonchalant. Like he won’t go home and fuck his fist in the shower with the echoes of your sighs filling his ears if you turn him down. You can see it in his eyes. What hinges on his offer and how much you’ll both regret it if the tension fizzles and dies in his SUV.

From where you’re sitting, it’s incredibly difficult to think with your head and not your hormones. Mingyu is hot, he’s nice, he seems decent enough. His behavior doesn’t hint at him being a creep. If he’s normal enough to fuck in his car, is he not normal enough to fuck in the comfort of a bed?

The thumb stroking your thighs and the hopeful eyes staring you down make the decision for you.

“Yeah, okay.”

With his address in your phone’s GPS, you trail after his SUV in your own car. The roads are familiar because they’re the same roads you drive when you return to your apartment that turns out to be only three blocks closer to the gym than Mingyu’s.

All this time he’d been so close and you never even realized. Did he think about you the same way you thought about him when he drove home? If he did, you’re in for a night.

Rolling into a space only a few down from where he parks, you pause to hype yourself up.

People have sex all the time. It’s no big deal. I can do this.

A knock at the window interrupts your spiral, finding Mingyu smiling sheepishly through the glass. The muscles in your chest squeeze when he opens the door and holds it for you to exit; and threaten to explode when his hand finds the small of your back and guides you towards the stairwell.

Footsteps echo down to the hall, Mingyu only a fraction ahead to lead the way to a non-descript door with a seasonal doormat that's seen better days.

“Ugh, this is it.”

His apartment is shockingly clean for a guy your age. Not clean in the ‘I don’t own enough shit to even be dirty’ way. No, Mingyu’s apartment is cozy. There’s throw pillows and blankets on the couch. He has a lamp and bookshelf in the corner and the walls are adorned with a collage of artwork thoughtfully pieced together. Several personal photos are littered throughout, some with an obviously younger Mingyu propped next to what must be a sister or a cousin, a few of him with friends. One of him and a familiar man with glasses, their faces blurry but the glee clear as they’re frozen in time. Your lips lift with a soft smile at the personal touches bleeding into every corner of his space.

Turning over your shoulder you ask, “You and the guy at the gym are friends?”

Mingyu’s watching you with something unidentifiable in his eyes, stepping forward to figure out which frame you're looking at until he’s only a foot behind you.

“Yeah, we went to the same middle school.”

“And this one?” You say, fingers tracing the edge of the wooden frame.

“My little sister.” Mingyu follows, still only a step behind.

“And I’m assuming these are your parents?”

“Actually those are Wonwoo’s parents.” He chuckles. “These are my parents.”

Mingyu’s arm reaches around to point at the correct photo, his chest brushing against your back.

“Wanna give me the tour?”

Mingyu manages to show you everything in five minutes. The living room and connected kitchen you’re already standing in, the door of the hall bathroom, and finally his bedroom. You take a seat on the edge of the bed, discovering the new smattering of details that uncover more about the man waiting with baited breath in the threshold.

“Why are you over there?” You ask.

With arms crossed and shoulders up to his ears, Mingyu resembles a kid waiting to be scolded rather than a man who tried to hook up with you in his car less than thirty minutes ago.

“I’m nervous.”

You can’t stop the satisfaction from spreading to your face. “I make you nervous?”

Mingyu pushes off the door jam, shuffling forward until he’s standing a foot in front of you. “Yeah. I don’t really do stuff like this.”

“Stuff like what? Try and fuck girls in your car?”

“Haha.” Mingyu mocks, face descending until he rubs his nose with yours.

Your eyes slip closed when his do, breathing each other's air. “Stuff like what, Gyu?”

Your hands find the material of his shirt stretched across his shoulder. Each brush of his lips across your cheek, down your jaw, until he finds your ear.

“I don’t sleep around with girls I’m not dating.”

Oh.

“We don’t hav—”

“Which is not the best way to ask you out.”

You press him out of your space, far enough that you can look him in the eyes and see if he’s serious. The tips of Mingyu’s ears burn red but he’s looking right at you despite how embarrassed he clearly feels.

“You’re asking me on a date?”

“Ugh, yeah. I think it’d be fun. But you don’t have to! If you just wanna do this that's fine t—”

Whatever words Mingyu was trying to say fizzle on the tip of his tongue as you pull him into a kiss. He curls over you, pressing you further into his bed with every fervent pass. Wedging one hand under the small of your back, Mingyu lifts you up and carries you while he crawls to the center.

Your mind wanders to all the other ways he can manhandle you into the mattress.

He settles flat against you, hips cradled between your own while delving into your mouth. You fill your hands with his ass, dragging Mingyu’s covered cock against your core. A groan backs apart your lips as Mingyu falls into the curve of your neck.

“This is a yes to the date by the way.” You pant now that he’s taken over, hands scratching up his back in an effort to get rid of his shirt. “In case that wasn’t clear.”

Mingyu’s clothes disappear over his head and across the room, yours following shortly after. The heat of bare skin on bare skin is better than anything until he takes one of your breasts in his palm and the other in his mouth.

Every curse you know flies through your lips as he sucks and pinches until you're sore between the legs.

He takes the squeeze of your thighs and the rock of your hips as a greenlight, hands leading where his lips follow until it’s nothing but your panty clad core an inch from his face.

“This okay?” Mingyu asks in the fat of your thigh, tongue trailing fire across the skin.

You nod with a sigh, “Mingyu, please.”

He doesn’t need much more than that, the fabric barrier gone in a blink and his nose traces your folds until he’s dying for a taste.

Mingyu eats pussy like he doesn’t need oxygen. The path of his pointed tongue around your clit is nothing short of precise, meticulously tracing every ridge and curve until the sheets stretch under your fingers. When he flattens it to pay broader attention, your legs squeeze and Mingyu’s hands force them wide around his shoulders.

Your feet flatten on the bed and thrust up his mouth, wet and crude with fingers in his hair and your whines in his ears. Every suck of Mingyu’s mouth forces the muscles in your neck to lerch until they hurt and your head falls back. He takes pride in the way you drip for him, making the best mess he’s ever had the privilege to clean up.

You reward him with an lavishing praise at the next twitch of your insides, “Fuck, just like that.”

Taking advantage of the slight arch in your spine, Mingyu’s hand sneaks under your back, fingers unforgiving as they dig into your ass. He curls your hips up and buries a finger in your core with mortifying ease.

Between your legs, Mingyu catches your eyes. Pupils blown wide, mouths bruised around stuttered breath. A matching set of debauched expressions. He’s more familiar like this; skin glowing with sweat, and hair matted to his forehead. Next time you see him at the gym you know it's all you’ll think about. Next time you're alone in your room, or the shower, or the grocery store. Or anywhere you’ve day dreamed about him before.

He leans back to watch the digit disappear, only to reappear soaking. “Feels good?”

“Give me another and it will.”

You savor the rhythm he sets, thick fingers working to prep you for what you felt under his shorts. His tongue is hard and wet at your clit, fingers stretching and spreading until your stomach dips and you nearly buck him off as your clit swells from abuse.

Your fingers pluck at your nipples and Mingyu apparently likes to watch because he manages more enthusiasm, forces his finger to crook just the right way, and continues to suck even after you start screaming.

“Oh fuck, oh, fuck, fuck, fuck!” You chant, voice cracked.

Something sounding suspiciously like a ‘thank you’ drops into the mix but Mingyu’s the only one to hear it. In his opinion, he should be the one doing the thanking; you just gave him enough spank bank material for the next six months.

You don’t dislike the taste of yourself on his tongue, his lips, his chin, his cheeks, and even his chest when you flip Mingyu over and aim to return the favor. He blushes when you lap against the hollow of his throat; embarrassed from the way he goes boneless with such simple affection.

He sinks into the plush of the mattress, propped up by the mountain of pillows at the headboard. Mingyu’s stomach stiffens under your tongue and the twitch blooms a smile on your face. Predictable.

“Sensitive?”

Your nails raking up the shape of his thighs turn the denial falling from his lips into a whine, and it makes you wonder what other sounds Mingyu will make with his cock in your mouth.

The vein bulging along the underside of his length gives your tongue something to trace along as you lap from base to flared tip, sucking down until it shines from spit and pre-cum. You take all you can until the curve of your throat protests.

Mingyu’s big and he’s loud.

“Oh God, shit.” He babbles with abandon, hands fisted at his sides until his knuckles turn pale.

You focus on the cock in your mouth rather than how pretty Mingyu’s chest would look covered in bite marks. How a bruise on his hip would be just visible when he reaches over his head to do pull ups, and red streaks from your nails on his bicep would make a great accessory.

A hand lands on the base of your skull, gentle until it's not. His thumb dips to stroke the bulge of his dick through your throat as you take him deeper. And like some ridiculous porno theres still an inch you’ll never be able to take even if you do nothing but let him fucking your mouth until the only thing you taste is cum.

“Fuuuuck,” Mingyu groans from a harsh suck on the upstroke.

He distracts you with his tongue on yours, keeping you from diving back down and destroying his ego from how quick you almost made him cum. Your one solace is the lazy grip you have on the base of Mingyu’s length, fingers tightening around the head while he cants into the squeeze.

You think Mingyu is going to plant you on his cock and make you ride it until one of you is crying. But he keeps pushing and pulling until you’re kneeling over his face, knees cushioned in the pillows and hands against the wall to steady you while he dives in again.

His head shakes back and forth, tongue out to swipe messily at your clit as you grind into his face. The last grip of sanity you have gives you the mind to reach back, jerking Mingyu off while he eats it, a cycle of moans moving through you; him into your folds when you squeeze from a grating pass off his tongue that has you whining to the ceiling fan.

“Shit, need you to fuck me.” You whine but don’t stop curling against the latch of his lips, legs stiff with ache.

It’s Mingyu who brings things to a halt, raising you away from his mouth until you're left on your knees while he stands to rummage in the drawer for a condom. You listen while the paint of the wall cools your forehead.

The hand at the dip of your spine makes you melt when he checks in, “Still okay?”

Nodding, you find him over your shoulder with a thick swallow. Mingyu’s nose follows the slope of your muscles, lips untying all the knots he’s worked into them over the past few weeks.

“Want it like this?”

“Yeah.”

You drop until your chest meets the bed and arch until it hurts just to put on a good show. Mingyu shuffles behind you, knocking your knees wider with his own, palms molding to your ass and spreading it apart to take a good look like he wasn’t tongue deep inside your pussy already. The room is nothing more than the sounds of grounding breaths; Mingyu watching the way your torso moves around the air, releasing a long exhale before moving closer.

The feel of his chest against yours was great, but the hard muscle of it along your back, his chain caught between and leaving a definitive mark, is life ruining. It shreds the last bit of humanity you’ve been clinging to since you dragged Mingyu to the parking lot and tried to stick your hands down his pants while leant against the passenger door.

No matter how well Mingyu stretched you for his cock it was never going to be enough. Taking the first inch nearly splits you in half. But you're soaked and needy; nothing short of the end of the world is going to keep you from getting the satisfaction of feeling him in your guts. You take it with measured breaths and affirmations to relax. Slow arches of his hips work him in until he’s flat with your ass and whispering absolute depravity into your ears.

“Fuck, you’re tight.”

Arching your ass higher, you whimper, “You’re huge.”

Your ass stings under his punishing hand, thrown forward by an involuntary buck of his hips.

“Don’t say that.”

You turn until you can look over your shoulder again, meeting wild eyes. “You feels so good.” You moan, eyelids low and wrecked.

“Didn’t—shit, think you’d have such a dirty mouth.” He bites into the side of your neck, sucking a bruise like a depraved teenager.

“I knew you’d have a fat cock.”

You get what you want so easily it's almost insulting; Mingyu’s hand forcing your face into the sheets and his hips rushing into you with pure need. Every prod into your cunt has you wailing. It’d destroy your self respect if you could think of anything beyond how he’s ruining you for anyone else.

Pillows topple off the edge of the bed as you scramble for a hold. Anything to ground you against the burn in your veins with every tight squeeze around Mingyu’s cock. His balls slap against your clit teasingly, more degrading than the way he has you bent in half.

“Harder,” you beg.

Mingyu falls back on his haunches, pulling you with him until you're sitting up right. His arm comes into view, curling around neck until your throat sits in the crux of his elbow and his hand latches on your shoulder; a crude headlock he uses as leverage to keep fucking into you. You’ve been choked but this is infinitely better. Whatever Mingyu wants to take from you, he’s in a position to do so.

“Gonna cum?” He nips into your earlobe.

His hand shoves its way between your legs, swipe roughly against your clit before you can even hope to answer.

A pathetic nod is all you manage thanks to the muscles gathered under your chin limiting your mobility.

Mingyu let's go then and your hands prevent a crash into the headboard, putting you back in the same position as before but you have to work for it now; ass bouncing in his laps as you ride him. Finding your balance, you drop one hand to your clit as Mingyu’s pinch your nipples.

“Let me have it, let me make you come." Mingyu pants into your spine. "Fuck you look so good like this, shit.”

He keeps rambling, flying with you towards the edge hand in hand; both breathless from the slap of your thighs against his.

“Mingyu, feel so good. Oh my god, oh my g—”

The softness of the pillows greets you once again while everything flashes white. Mingyu scrambles behind, fucking you into the mattress while you soak his cock. Muscles twitching, teeth ground till they crack, you come and come and come while begging him to do the same.

Mingyu gives in without hesitation, all his weight behind his hips as he fills the condom; dragging you back with an arm around your waist. Every jerk of his cock against your walls from the force makes you vibrate until he’s slipping out, soiled and used against the back of your thigh.

The last thing you register is his lips finding your shoulder again, rubbing back and forth as he comes down.

You fall asleep under the heat of his body for who knows how long, content in the mind shattering numbness of what just happened. Mingyu seems to feel the same, dead weight hanging half off you so you can at least manage to breath.

When you wake, whether it's twenty minutes or two hours later, Mingyu is snoring into the pillow, still naked. His lips pout in his sleep and you swallow the urge to shower them with kisses thanks to the drool at the corner of his mouth.

Even without the covers, you're warm. The kind of heat that slips over your skin, sinks into your bones and keens for you to fall asleep and stay. But Mingyu asked you on a date, not to spend the night. And you’d hate to assume and ruin whatever this is before it as a chance to start.

“Where are you going?” He pouts.

You don't make it two inches out of his arms before he’s pulling you back, tangling them around you so there's no chance of unnoticed escape. Mingyu digs his nose into your cheek and waits for an answer like he has all the time in the world.

Something tells you if he knew you were attempting to head home, Mingyu would throw a fit. And what use is that when you want to see what a night sleep with a giant human furnace is like?

“Bathroom.”

Adding to the list of information you’ve learned, Mingyu is a stage five clinger. He latches on to your back, guiding you into the shower stall for a quick spray down that leaves half your face, part of your thigh, and almost none of him clean.

He falls asleep against the base of your skull while brushing your teeth, because of course he has a stash of extra toothbrushes under the sink just in case.

And when you crawl under the fresh sheets, he pulls you into his chest, leaves a kiss against your forehead, and tells you he can’t wait for your breakfast date tomorrow.
