Work Text:
Atsumu wasn't planning on staying late after practice today, but when his knee starts acting up he decides to take his time and stretch thoroughly for almost half an hour. When Atsumu's finally done he's all alone in the huge gym, save for a few coaches and staff milling about. He swiftly gets to his feet and heads for the showers because damn, he's starving.
The locker room is quiet save for one shower running and Atsumu doesn't think much of it at first. But when his eyes zero in on the neon coloured hoodie hanging on a hook above the only bag left on the benches save for Atsumu's own, his mouth goes dry.
Kiyoomi.
It's well known that Sakusa Kiyoomi never undresses around other people and always showers last. He arrives at the gym already in his workout clothes and doesn't even start taking off his shoes until most people have left the locker room after practice.
But he must've gotten sick of waiting because he's in the shower right now and Atsumu feels a flush creep up his neck at the thought. Him and Kiyoomi have been at each other's throats at every opportunity since they first met a couple of years ago. However, Atsumu would be lying if he said he doesn't find the spiker attractive. Kiyoomi's pale skin, dark eyes, and shiny curls make his stomach twist and his face heat up.
It's only gotten worse as they've both gotten older, Kiyoomi filling out his workout clothes better and swapping his longer curls for an undercut. Atsumu has had to excuse himself to the bathroom mid-practice more than once during this year's camp. In the privacy of the cold bathroom he would fist his cock to completion while thinking about Kiyoomi's lips, his hands, his ass.
And now they're about to be naked in the same space together. It's a fairly large space specifically meant for nakedness, but still. Atsumu wills down his half-chub as he undresses and wraps a towel around his waist before heading for the showers.
"Hey, Omi," he says as he reaches the doorway separating the areas. "It's-"
"Miya?" he hears Kiyoomi say, his voice coming from the furthest shower stall. "I thought... never mind."
Atsumu blushes at the fact that Kiyoomi is naked, right now, while speaking to him. God, he needs to get laid.
"Yeah, um, I didn't wanna sneak up on ya," he continues, stepping into the shower room and picking the stall furthest away from Kiyoomi. "'M gonna be over here and 'm not gonna look at ya or anythin', I promise. Okay?"
There's a slightly too-long pause before Kiyoomi replies. "Okay."
He sounds... nervous? Almost scared? Atsumu shakes the thought off as he hangs his towel up and turns the shower on. He knows Kiyoomi doesn't like being naked around people but Atsumu needs to shower and he's not intending to overstep any boundaries. He's just going to be here, showering, minding his own business.
It's less than a minute before Atsumu hears the other shower turn off, followed by soft footsteps padding along the damp tiles. He diligently keeps his eyes on the wall, expecting Kiyoomi to walk past him back into the locker room.
When the footsteps stop just shy of his stall, Atsumu stops breathing.
"Miya?" Kiyoomi says, his voice sounding small and insecure. Atsumu hates it.
"Yeah?" he replies, breathless and resisting the urge to turn around to look at Kiyoomi.
"Do you... want to look at me?"
Atsumu thinks he might have misheard, so he switches off the shower and turns his head slightly, eyes fixed on the tiled floor. "What?"
"Do you want to look at me?" Kiyoomi repeats, his voice trembling a little. Atsumu swallows around the frantic heartbeat in his throat.
"Yeah, Omi, I do."
"Then you can," Kiyoomi whispers, the quiet permission sounding strangely loud in the large, empty room. Atsumu puts his hand on the shower wall, slowly turning around and looking over his shoulder. Kiyoomi's fingers are curling around the edge of the stall, white-knuckled and trembling, but that's all of him Atsumu can currently see.
"Are ya sure?" he whispers back, standing still as a statue as he watches Kiyoomi's fingers twitch and grip the wall harder.
"Yeah," Kiyoomi says, voice a little louder now. "Yeah, I... I want you to look."
Atsumu's stomach does a somersault down into his toes and back, making his breath stutter as his fingers tense on the tiled wall. He turns around fully, reaching out for Kiyoomi's hand but stopping just short of it.
"Then c'mere," he says softly, sucking in a breath when Kiyoomi's fingers flex outwards and their pinkies touch. Kiyoomi freezes for a second before reaching forward to lace their fingers together, his skin cold to the touch. Kiyoomi squeezes his hand, takes a deep breath, and steps around the corner.
The first thing Atsumu sees is those dark eyes, intense and piercing under a mop of wet curls. His eyes trail down, over Kiyoomi's pouty lips and pale neck, down down down across porcelain skin dotted with moles and marked by scars. He bites his lip when his gaze falls on a sparse happy trail, leading down into a neatly trimmed bush.
" Kiyoomi, " Atsumu breathes, taking a step forward as his eyes continue to roam across the body of the man before him. "Fuck, yer gorgeous."
Kiyoomi blushes a pretty pink, casting his eyes down and then gasping softly. "Miya... you're hard."
Atsumu looks down and fuck, he is. He'd been so focused on Kiyoomi that he didn't even notice. He looks back up to meet Kiyoomi's gaze, finding it heavy and wanting.
"Omi, can I... touch ya?"
Kiyoomi nods and steps closer, their hands still clasped together. A shiver runs down his body, nipples pebbling in the cold room, and Atsumu quickly reaches behind himself to turn the shower back on. He steps backwards, pulling Kiyoomi with him into the stream of warm water. It relaxes them both and they melt into each other, Kiyoomi's hand on Atsumu's cheek and Atsumu's arm around his waist.
"You're so warm," Kiyoomi whispers, and then they're kissing. It's soft, tentative, and Atsumu feels like he's floating. His heart is almost beating out of his chest as their bodies shift closer together, his hard cock pressing up against Kiyoomi's abs. Atsumu groans, breaking the kiss to rest his forehead on Kiyoomi's shoulder as he slowly rolls his hips.
"Ya feel so good," he murmurs against Kiyoomi's collarbone, his hands sliding down wet skin to gently grab his ass. "Fuck, Omi, yer so fuckin' pretty."
"Touch me, Miya," Kiyoomi says, voice soft and breathy in Atsumu's ear. It sends a pleasant shiver down his spine and makes his cock jump.
"Only if ya call me Atsumu," he retorts, pressing gentle kisses to the pale expanse of Kiyoomi's neck.
"Atsumu," Kiyoomi breathes, grabbing his right wrist and guiding him to where he needs it most. "Touch me here."
Atsumu's brain short-circuits when his fingers sink into Kiyoomi's cunt, and he can't help but imagine what that slick heat would feel like around his cock. He groans and bites Kiyoomi's shoulder, gently moving his fingers back and forth as he tests the waters.
Kiyoomi guides his touch, gasping when Atsumu's fingers find his clit. Before long Kiyoomi is moaning in his ear and bucking his hips against Atsumu's hand, wordlessly begging for more. Atsumu plunges his fingers into Kiyoomi for just a second before pulling away, sucking on the digits and groaning at the taste.
"Lemme taste ya properly," Atsumu pleads, reaching back down to circle Kiyoomi's clit with a featherlight touch.
Kiyoomi sucks in a shaky breath. "Y-you want to?"
"Fuck yeah," Atsumu groans, speeding up his fingers ever so slightly. "Want ya to ride my face and come on my tongue. Can I, Omi? Please?"
"Okay," Kiyoomi says, breathless and trembling as Atsumu pushes him up against the wall and sinks to his knees in one fluid motion. He attaches his mouth to Kiyoomi and eats like it's his last meal, pushing two fingers up his soaking cunt to find his sweet spot.
Kiyoomi curses and bucks, fisting a hand in Atsumu's hair and one over his own mouth to muffle his sobs of pleasure. Atsumu starts off slow but once he's figured out what makes Kiyoomi tick he speeds up, his fingers and tongue moving with a singular purpose.
"Oh shit, " Kiyoomi groans, his hips jumping against Atsumu's face as he rides his lover's tongue. "Shit, shit, fuck! Atsu, oh my god, Atsumu-"
Atsumu's neglected cock throbs and he knows it's leaking but he ignores it, focuses all his attention on making Kiyoomi make more of those noises. Slick is running down his chin, mixing with the water from the shower, and he's never tasted anything better than Kiyoomi's pussy in his life. He wants to stay buried between these pale thighs forever.
Kiyoomi has both hands in Atsumu's hair now, his moans echoing in the room. He uses his grip on the blonde strands for leverage, desperately riding Atsumu's face as his legs shake from the effort.
"I'm close," he pants, crying out when Atsumu groans against his clit and redoubles his efforts. "Oh my god, you're gonna make me come, oh fuck! "
Kiyoomi comes with a cry, his cunt pulsing around Atsumu's fingers as his entire body shakes with the force of his orgasm. Atsumu works him through it, lapping up all his slick and sucking on his clit until Kiyoomi weakly pushes him away. Atsumu surges up and kisses him, relishing in the way Kiyoomi groans when he tastes himself on Atsumu's tongue.
"Ya taste so fuckin' good, Omi," Atsumu murmurs against Kiyoomi's lips, reaching out for his hips and pulling their bodies close together under the stream of water. "Will ya let me do that again sometime?"
"Yeah," Kiyoomi nods, breathless and trembling in Atsumu's arms. His cheeks are flushed a deep red and he looks more beautiful than anyone should have the right to. "I'd like that."
"Good," Atsumu hums, diving in for another kiss. Kiyoomi melts into him and rolls their hips together, making Atsumu gasp as he's reminded of his aching cock. Kiyoomi pulls back and looks down, chewing on his bottom lip.
"'S okay," Atsumu says with a small chuckle, rubbing soothing circles into Kiyoomi's shoulders. "Ya don't have to do anythin' ya don't wanna, I can take care of it myself."
"I want..." Kiyoomi begins, looking back up at Atsumu with eyes even darker than before. "I want to feel you. I really, really want to."
Atsumu gapes at him, blood rushing in his ears. "D'ya mean...?"
"Will you fuck me?" Kiyoomi says, clinging to Atsumu and mouthing at his neck. "Please, Atsumu, I want all of you."
"Omi, baby," Atsumu groans, wrapping his arms around Kiyoomi's slender frame and squeezing hard. "Ya have no idea, absolutely no idea how badly I wanna be inside ya. But we don't have protection, baby."
Kiyoomi blinks up at him, eyes a little sad. "You don't have any?"
"Nah, I didn't think... never mind," Atsumu mumbles, craning his neck to kiss Kiyoomi's forehead. "So unless ya have any, we're shit outta luck."
"Fuck," Kiyoomi huffs, pressing their bodies together and once again putting friction on Atsumu's straining erection. "I want you, Atsu, fuck, fuck ..."
Atsumu groans into Kiyoomi's neck, feeling his resolve crumble more with every passing second. Kiyoomi's breath is hot in his ear and Atsumu is shaking with how badly he wants him. He's harder than he's ever been in his life and he can't stop moving his hips. When Kiyoomi snakes a hand between their bodies and grabs Atsumu's cock, his knees almost give out.
He expects Kiyoomi to start jerking him off, so he makes a soft sound of surprise when his dick is pushed down slightly as Kiyoomi shifts. The sound quickly turns into a punched-out groan as Atsumu feels his cock slide between Kiyoomi's wet folds.
"Omi," he chokes out, gripping his lover's hips harder as they slowly rock together. Kiyoomi's cunt feels heavenly on his cock and he can't think straight. "Baby, I... fuck -"
"Please fuck me," Kiyoomi begs in his ear, and Atsumu has to focus all the willpower he has on not coming on the spot. "You can just pull out, right? If you really don't want to then say so but fuck, I need you so bad."
Atsumu is just a man. A man with an aching erection and his long-time crush throwing himself at him, wet cunt teasing his straining cock, and begging to be fucked. He's done for, a goner.
Atsumu growls as he pushes Kiyoomi up against the wall, the warm water from the shower still cascading over them both. Kiyoomi gasps but holds on, lifting his leg to hook into the crook of Atsumu's elbow. Atsumu grabs himself with his other hand, kisses Kiyoomi, and pushes in.
It's everything he's ever dreamed of and more. Kiyoomi is hot and tight, squeezing around him on every thrust in a way that's going to make him lose it way sooner than he'd like to. But he can't stop, can't resist the feeling of Kiyoomi swallowing him up and taking him perfectly.
"I won't last," he pants against Kiyoomi's mouth, his hips snapping faster and faster as he chases his peak. "Omi, yer so- oh my god ."
"You feel so good, oh fuck, Atsumu," Kiyoomi moans, bringing a hand down between their bodies to work at his clit. "Your cock... holy shit! "
"Come for me," Atsumu urges, adding a dirty grind to the end of his thrusts that makes Kiyoomi's eyes roll back. "C'mon, lemme feel ya."
Kiyoomi goes over the edge a few seconds later, a silent scream on his lips as his face draws up in pleasure. Atsumu follows very soon after, still holding Kiyoomi's leg up as he pulls out and strokes himself hard and fast until he spills white all over Kiyoomi's pale abdomen and dark bush. Atsumu lets Kiyoomi's leg down and they fall into a kiss, messy and panting as they let the water wash them clean once again.
"Can I take ya on a date? Like, right now?" Atsumu asks as they break apart, breathless and unwilling to let Kiyoomi go now that he's had him so close.
Kiyoomi smiles at him, impossibly soft, and gently cups his jaw. "You can. But let's get dressed first, yeah?"
