Work Text:
when kai asked him out, and beomgyu had—very excitedly—said yes, he thought it’d be easy. kai was nice and tall, unbearably sweet, and exactly beomgyu’s type. he dressed in big shirts and loose pants and looked like the cuddliest thing that beomgyu had ever seen. he wasn’t the biggest person that beomgyu had dated, but that wasn’t a problem. kai was perfect in every way possible, and beomgyu wouldn’t let the topic of physique faze him.
until today, the first time he’d stayed the night at kai’s apartment. until kai took his shirt and pants off in front of him to change into his pajamas. until beomgyu realized that his sweet, adorable boyfriend of two months was much more than big, and more like a greek god, the ones they carved giant marble sculptures of.
because kai was ripped.
“are you gonna get dressed?” kai said distantly. beomgyu could barely hear him over the roar in his ears, the sound of blood rushing. he couldn’t take his eyes away. kai wasn’t even doing anything extraordinary, like flexing or flaunting them, but beomgyu was addicted to the way his muscles moved as kai performed the most basic of movements. when he bent down slightly to slide his pants up his legs and his thighs flexed, or how his biceps shifted under his skin just by grabbing something. and kai was oblivious to it all. like his body wasn’t perfect. like he wasn’t sculpted by the gods or some other higher being horny enough to make him look like this.
beomgyu was salivating. in the back of his mind there was some conscious thought. stop looking at your boyfriend like a piece of meat before he breaks up with you. beomgyu, for once, tuned out the little voice inside his head.
“–gyu-hyung? beomgyu-hyung?”
oh. right.
“yes?!” beomgyu shouts out, too loud. kai was still shirtless. a broad neck flared down into broad shoulders, with a strong back that beomgyu wanted to touch. kai’s pecs were huge. they were pure muscle and a dream, beomgyu’s dream, of pressing his face to kai’s chest and breathing the musk from the space in between them. beomgyu wonders what they’ll feel like in his hands, though he predicts they’ll be hard, firm, bouncy. kai’s arms are another deal. how much could kai bench press? 100 pounds? 200? could he sweep beomgyu off his feet?
and kai’s abs. they weren’t chiseled out from stone, but they were there. little dips on his torso that made him so much thicker. would beomgyu even be able to wrap his arms around kai fully? no, beomgyu thinks, his arms were too short. but his legs could do it, surely.
“i’m okay,” beomgyu says in a daze. kai hums a little cute noise, but the furrow in his brow doesn’t go away. how could kai be so cute but look like this under all of his clothes? “just-uhm…thinking.”
“about?” kai asks. when he grabs his pajama shirt, a soft blue cotton, beomgyu can already see certain doom. the moment kai put the shirt on beomgyu would never see this again. his chest, his arms, his back. it was too early for all of this to be taken away, not when beomgyu hasn’t tasted him, touched him, felt him.
“can you- can you keep the shirt off?” beomgyu blurts before he can help himself. “it’s just–it’s kinda hot y’know? i wouldn’t want you to like, heat up or something…haha.”
kai stares at him like he’s grown two heads. “it’s raining outside, gyu-hyung.”
right. the rain was the only reason why kai had let him stay over rather than walking beomgyu to his own apartment.
beomgyu, honestly, didn’t think this far. but before he can think up another excuse, kai murmurs out quietly, “i can leave the shirt off, if you want.”
“yes,” beomgyu says in a rush. “i want. i want to–“
“to what?” kai urges. he takes a step closer to beomgyu, the yellow light of his room spilling against him and making him glow. kai has definitely caught on. he crowds beomgyu to the wall, cages him in with those giant arms of his, noses against beomgyu’s neck like he can smell the rain on him. we’ve never done this before, beomgyu thinks, but he doesn’t try to break out of kai’s hold. instead he indulges, bringing his hands from kai’s hair down.
“i want to touch you,” beomgyu says under his breath. his fingers glide over kai’s skin, soft and a little sweaty, before they start grabbing. he kneads at kai’s chest, feeling his pecs. they are indeed firm, but bouncier than beomgyu thought. kai gasps against his neck, a wet sound, so beomgyu moves on, files the information away in his head for later. finally he grabs onto kai’s arms and his hands don’t even come close to wrapping around them fully. but they feel thick and they move under beomgyu’s fingers, unexplainably arousing. how much can they hold , beomgyu thinks. how much can kai do?
surging up, beomgyu kisses kai’s cheek, whining low in his throat to show kai where beomgyu really wants him. the younger boy gets it, kai always does, and connects their lips with a ferocity that only beomgyu can understand. his hands clench kai’s arms still, the feeling of being trapped between them sending tingles up beomgyu’s spine. the space between them is warm, with kai moaning into his mouth as their tongues press together. it’s good, it’s so good, but beomgyu needs more.
“can you–“ beomgyu pants against kai’s mouth. “can you please–“ kai—beautiful, smart, strong kai—doesn’t think twice before he plants both hands under beomgyu’s thighs, fingers brushing his ass, and lifts.
“fuck,” beomgyu whispers. kai’s lips are back on him, pressing searing kisses to his mouth, his cheek, his chin before the younger boy settles somewhere on his neck to suck. beomgyu’s legs wrap around kai’s waist, tightening and loosening around the boys firm torso. it’s better than he imagined, so much better. from this angle he can grind against kai’s abs and feel every ridge. against his better judgement, beomgyu does, and the slide is glorious. he moans deep in his throat, sure that kai can feel it against his neck, and feels his pants get tighter, wetter.
“we,” kai pants, kissing beomgyu in-between his words like a man addicted. “we should stop.”
they should. even now, pressed against the wall and furiously making out, was new territory. the most they’d gone previously was soft petting, little kisses and makeouts with beomgyu’s hands safely on kai’s neck, the younger boys hands never straying from his waist. now, kai gripped his thighs so tight beomgyu would have bruises tomorrow, fingers twitching to brush against the sensitive globes of beomgyu’s ass. beomgyu hadn’t stopped running his hands up and down kai’s arms. they’ve only been dating for two months, and this was kai’s first real relationship. they were supposed to be going slow. they should stop.
“yeah, we should,” beomgyu leans his head away from kai, chest heaving with heavy breaths. he’s not upset, and when he looks into kai’s eyes, the other boy isn’t either. both of them are satisfied, if not with the make-out session but with the hurdle they crossed in their relationship. they could go further now. further than pecks and holding hands, maybe further than this, and do more than heavy petting and grinding. “let’s just stay like this, for a bit.”
kai smiles after he presses one last kiss to beomgyu’s neck. “just for a bit,” he says, though he shows no signs of getting tired. beomgyu wants to stay in his arms like this forever.
“so, hyung,” kai nuzzles against his cheek. “if i knew you liked muscles so much i would've undressed in front of you way earlier.”
beomgyu colors, not even trying to hide his face. “i knew you were big, but who knew you were this big.” he emphasizes this with yet another squeeze to kai’s bicep. beomgyu was addicted, rightfully so.
kai takes in a breath, one that seems hot and bothered, before he hangs his head down, bangs covering his face. “don’t say it like that,” he says. his hands tighten around beomgyu’s thighs. “we need to stop.”
oh. so the thought of being big aroused kai too. beomgyu could work with that. would work with that.
“okay,” beomgyu giggles, placating, though kai knows its filled with mischief. it rolls his stomach in a good way, in an expectant way. “we should sleep now, huh?”
the room is still warm, the lamplight just as bright. kai feels so warm against him, and beomgyu doesn’t want to give this up. still he lets go of the deathgrip he has on kai’s arms, leans away from him so the only thing connecting them are beomgyu’s legs wrapped tightly around his torso, kai’s hands holding him up. they’d do this again, and again, and again. they’d do much more than this, beomgyu only has to be patient.
kai hums, agreeing. though he doesn’t move.
“a few more minutes.” he says. kai’s arms don’t shake or twitch with exhaustion. kai’s already been standing for almost twenty minutes, beomgyu in his arms, unfazed.
yeah, beomgyu thinks. kai can bench 200, easily.
