Chapter Text
“I remember Kiyoomi-kun barging into a lecture hall at the last second for an important exam but you can count on him to be wide awake at three in the morning, looking up weird shit on wikipedia.”
“Omi-kun can’t fucking wake up for his life in the morning. Remember when he joined? We’d leave the dorms realizin’ he wasn’t even awake yet.”
“Yes, I saw that movie twice. No, that’s because Atsumu usually falls asleep thirty minutes in, we always watch it several times so he gets the whole… picture.”
“Akaashi, they won’t join karaoke again tonight. You know how they over-do it in practice all the time and then conk out when we try to have a nice outing. And I was so looking forward to it…”
“‘Tsumu’s the heaviest sleeper I’ve ever met in my entire fuckin’ life. It’s not even funny when all ya want is to prank his ass but he’ll sleep through it. Trust me.”
“Sakusa always sees things through. That includes his night of sleep. Especially if he had a bout of insomnia. Trust him to catch up on that. I’ve seen him do this since we were kids.”
Whether it’s Kuroo, Kiyoomi’s roommate in college, Atsumu and Kiyoomi themselves, a teammate like Bokuto or their family… Everyone will always more or less tell the same tale. Atsumu and Kiyoomi are terrors in the sheets. Not in the sense one might think.
Their sleeping habits are a nightmare. And as Osamu and Motoya stated, it was the case long before they met. It didn’t get better once they got together. One would have thought they’d even out the corners. It actually got worse. They tire each other out. They challenge one another constantly and when they’re not, each other’s presence makes it too sweet to stay awake.
There’s something soothing about sleeping together with a loved one. Dozing off in a lover’s arm, lulled by their slow breathing. The non-existent pressure of having to stay awake because their partner knows what it’s like to be crushed at the end of the day. After all, they do everything they can to be thoroughly destroyed by the time they get to bed.
The only problem they had to face when it comes to meeting their sexual needs found its solution naturally, with easy communication. There was no reason for Atsumu and Kiyoomi not to understand each other on this subject too.
“But I want to bone you so baaad,” Atsumu had whined, hugging Kiyoomi from behind.
“You fell asleep three times already since we started the episode.”
“Tsk. I thought ya didn’t see the third one,” Atsumu had mumbled.
“You literally drooled on my shoulder.”
“Fuck me.”
“I would if I wasn’t as exhausted as you are.”
The mopey exchange had turned to a very interesting and fruitful conversation. They had been dating for five months then, known each other for years. It was easy to reach the same conclusion.
“I don’t mind if ya fuck me in my sleep.”
“I wouldn’t have a problem waking up to you sucking my dick.”
From there, it had only been a matter of details, a bit of questioning when it came to each other’s boundaries, and then, neither Atsumu or Kiyoomi would find themselves frustrated ever again. They’d never been the horny freak type and they had a solution for when they’d be.
⁂
“‘m’not runnin’ tomorrow,” are the last words Atsumu uttered before he fell into a deep slumber.
Boot camp training starts in two days so he and Kiyoomi both agreed to spend the day doing nothing remotely close to physical training. No morning run, no hitting the gym, no evening spent on court to practice their new combo.
The only physical activity they didn’t rule out requires for them both to be involved. It’s nice because they haven’t fucked much lately and although it’s fine by them, Atsumu does want Kiyoomi right now. He wants his boyfriend and it’s perfect because it coincides with a day off. They don’t even have to be both pro-active. Which is fortunate, because Atsumu is stirring awake at eight, while Kiyoomi is still dead to the world.
He’s not a heavy sleeper like Atsumu, but with his fucked up sleep cycle, he’s propably still far from his next REM phase. Kiyoomi’s breathing is even, slow. He’s laying on his stomach, arms hugging the pillow his face is pressed into. Warmth spreads around him like a second blanket, his skin hot under Atsumu’s touch. Kiyoomi’s body is the most pliant when he’s in this state.
The realization that he’s laying there for Atsumu to take makes Atsumu’s heartbeat speed up like he’s hitting the first sprint of a cold morning run in the winter.
Making love to Kiyoomi is never the same twice. They found out they’re versatile in many ways, not just because they enjoy taking turns when it comes to basic dynamics. Atsumu can lose his mind being fucked senseless by a pent-up, frustrated Kiyoomi after a complicated game and be as crazy for a passionate makeout session on the couch where they whisper sweet nonsense to each other without ever touching each other’s dicks. He loves it rough, sweet, over the kitchen counter, in the sheets, quick, when it takes so long they can’t finish, when they come together… When they’re wide awake and when one goes out like a light.
Atsumu rolls his shoulders, neck, taking his sweet time to stretch the last bit of drowsiness away. He never looks away from Kiyoomi’s nape as he does so. His lover is facing away from him because Kiyoomi is a weirdo who insists on having Atsumu cuddling him at night although he can’t stand it when there’s something else than a pillow in his face while he sleeps.
Atsumu has been the big spoon to this gangly long dude for the past five months but sacrificing his left arm isn’t too big of a price to pay to get to spend every night in Kiyoomi’s bed.
Atsumu gets his sweet revenge when they travel for away-games. Kiyoomi allows him to drool on his jacket — sometimes even his neck — during long-ass bus rides. He’d rather die than use a travel pillow and Kiyoomi knows it all too much.
At the end of the day, they’d do anything so their significant other can catch some well deserved rest. Sometimes it costs them precious moments to share some intimacy. At least, it was the case until they realized they could indulge in each other no matter the time of night, or day.
Atsumu is done stirring and he doesn’t want to lose another minute. He’ll savor each second he has before Kiyoomi wakes up, because — as Atsumu was surprised to find out — he really feels an extra thrill in taking Kiyoomi when he’s in this state.
Oh, it gets Atsumu’s dick fucking hard when Kiyoomi barks back and bite. It always has. But there’s something about that straightforward asshole being quiet that makes Atsumu’s stomach flutter like nothing else. It’s two secrets in one, a double privilege Atsumu owns alone.
Kiyoomi isn’t the discreet aloof guy everyone thinks he is. He’s brazen and outspoken when needed and Atsumu can’t get enough of this Kiyoomi. He can’t wrap his head around the fact that the Kiyoomi the world thinks they know can talk dirty to him in bed and even on court when no one’s listening. He drops the worst things in Atsumu’s ears with his deadpan tone and Kiyoomi just smirks to himself, leaving Atsumu hanging.
But then, mornings like this, when not even a teammate or a friend can walk in on them… It’s yet another side of Kiyoomi that’s all for Atsumu to consume.
Atsumu makes sure Kiyoomi stays warm, the covers drawn all the way up his back so the fresh morning air doesn’t tickle him, shortening the time they have like this. Atsumu will get too hot underneath them but he doesn’t mind. Getting sweaty has never been a problem, especially when it’s for such a good reason.
Eating Kiyoomi’s ass is, by far, one of the best reasons Atsumu can think of so he crawls down Kiyoomi’s body and nestles between his legs. One of them is already bent at the knee, so Atsumu just moves the other a bit more to the side with care so he can spread Kiyoomi.
Atsumu doesn’t hold back his shaky breath, not really scared if that tickles Kiyoomi. Kiyoomi’s brain seems to like to indulge in whatever happens in his sleep because so far, everytime Atsumu has done something similar, he’s got the most interesting reactions out of Kiyoomi’s body. Most of them involved him being in a slumber.
Atsumu’s hands splay over Kiyoomi’s cheeks, parting them while he ruts against the mattress. It’s going to feel too good, too soon. Atsumu needs to be careful because he woke up with a light morning wood and it can only get worse from here. He needs to focus on Kiyoomi.
Atsumu can’t help and bites his bottom lip before diving in. He’s getting a fucking treat.
“I’m gonna ruin ya,” he whispers to himself, heart racing.
Then he shuts his mouth and presses his lips to Kiyoomi’s taint. A telltale shiver runs down Kiyoomi’s body; only sign his sleep is being disrupted. Atsumu doesn’t wait for him to wake up. He laps a broad stripe up Kiyoomi’s taint, from the base of his balls all the way to his hole. It flutters under the pressure of Atsumu’s tongue.
Fuck, Atsumu is moaning against Kiyoomi’s skin but that was too hot. So hot Atsumu’s hips roll by themselves, cocks filling up and dragging onto the sheets. He’s craving the friction, some sweet relief.
Atsumu loves the taste of Kiyoomi. Another privilege that’s his alone. Kiyoomi had never allowed anyone to do this to him before they started dating. Now his eyes light up when Atsumu foregoes the lube on purpose and tells Kiyoomi he’s a bit too tight to be fucked right.
Kiyoomi won’t be too tight this morning. The numbness caused by his blissful sleep makes him loosen up so fast it’s ridiculous. Kiyoomi can be uptight but it’s so easy to make him unwind when he’s unguarded.
Atsumu licks up and down his crack, teasing himself more than he’s teasing Kiyoomi, before the tip of his tongue probes his entrance. There’s a heavy sigh somewhere above Atsumu and Kiyoomi hugs his pillow harder. Someone’s not aware of what’s happening to him, but someone’s brain is sending signals. Atsumu’s dick twitches. He restrains himself from humping the mattress, tongue breaching Kiyoomi’s hole. Atsumu is a starved man and Kiyoomi is a whole fucking meal.
He pulls back, gathering saliva at the back of his throat, drawing enough spit on his tongue so when Atsumu dives back in, the glide is easy and smooth. It trickles down Kiyoomi’s taint, making his waist jolt this time, but Atsumu isn’t concerned by it. Instead he fucks his spit inside Kiyoomi with his tongue, before bringing his thumb closer to Kiyoomi’s entrance to keep him open. Atsumu’s other hand brushes down his ass, giving a squeeze, then he’s pushing his index finger inside of Kiyoomi.
It’s so easy, so warm. Atsumu wants his dick as wet as his fingers, but not just yet. Not when Kiyoomi can take more than that without stirring one bit. Atsumu takes it as a challenge. After he gets knuckles deep with one, he pushes a second finger inside Kiyoomi, kissing his rim before Atsumu stops playing with his tongue. He could eat Kiyoomi all day long but there’s so much he wants to do before Kiyoomi wakes up and he needs to open him up thoroughly before anything else.
Atsumu misses his prostate on purpose with each back and forth, twisting and crooking his fingers in all possible directions but the one that could send fatal signals to Kiyoomi’s brain.
He’s made Kiyoomi come on his fingers once, and it woke him up on the spot. Atsumu doesn’t need to give that kind of pleasure to his boyfriend when he’s unconscious. He’ll save it for when Kiyoomi can enjoy it to its fullest. The only thing that matters here is for Atsumu to make Kiyoomi’s body relax — and maybe give him a few pleasant dreams for when he’s about to wake up.
Adding a third finger shows the limits of the lack of lube. There’s some resistance and Kiyoomi groans at the stretch. Atsumu is quick to worm his way out of the covers to grab the bottle on their bedside table.
But then he can’t help it. As he’s on all four above Kiyoomi to reach for the lube, Atsumu bends over him to check on his sleepy face. His heart pangs in his chest at the sight. Kiyoomi’s mouth is slightly open, an air of bliss written all over him. Atsumu wants to kiss him. He wants his tongue down Kiyoomi’s pliant mouth. Atsumu wants Kiyoomi to wake up with a feeling of yearning he doesn’t understand before drowning into a kiss. Atsumu doesn’t. He needs Kiyoomi to remain oblivious for a bit longer.
There’s something he can’t help but do, though. He reaches for Kiyoomi’s lips with the fingers he used to open him up. Atsumu wouldn’t do anything Kiyoomi doesn’t allow him to do when they’re awake. Lucky for him, Kiyoomi is a bit on the nasty side sometimes. There are so many things Atsumu considers himself lucky with when it comes to Kiyoomi. The simple fact that Atsumu discovered himself in bed thanks to Kiyoomi being his partner is sheer luck. And then, there are all the things they discovered together, learned from each other. The dos and don’ts, the things they weren’t aware they liked. The things making their guts churn inexplicably although they never thought about it before getting together… Sometimes they surprise each other, sometimes they surprise themselves. Sometimes they laugh it off because it’s gross. Sometimes it makes them hard and fall in bed.
Atsumu pushes his fingers past Kiyoomi’s lips just enough to hook them behind his teeth and pull his mouth open wider. Kiyoomi sighs. Atsumu pulls them out immediately.
Kiyoomi groans, turning so he can rub his face in his pillow but when he resurfaces again, he’s still sound asleep. Atsumu releases a breath he didn’t know he was holding, then positions himself over Kiyoomi’s body again. That was close. He needs to hurry.
Atsumu uncaps the bottle of lube, pouring some into his palm to warm it up before going back to work. This time, he gathers Kiyoomi’s legs under him and stands over the back of his thighs. Atsumu doesn’t dare to sit, his weight would alert Kiyoomi. He can’t gather the covers over their bodies anymore, so it’s a matter of seconds — minutes if Atsumu gets lucky — before it disturbs Kiyoomi’s sleep.
Atsumu leans forward, a hand propped on the mattress next to Kiyoomi’s flank, the other sneaking back between his cheeks to press his lubed up fingers to Kiyoomi’s hole. Atsumu gets three of them in easily, pumping them without feeling any resistance which gets to his head fast. He’s rock hard by now. All Atsumu wants is to be inside Kiyoomi.
That’s why he goes to straddle his ass, spitting in his so-far clean hand to fluff his dick and line himself up. Atsumu looks down at the gleaming skin, pumping his fist around his cock as he squeezes Kiyoomi’s ass again. He’s going to feel like heaven, just tight enough to suck Atsumu in.
Atsumu’s dick slips between Kiyoomi’s cheeks, his length rubbing back and forth, the lube spread there easing the slide. It’s so hot, Atsumu isn’t going to last long.
He bites back a moan when the head of his cock catches at Kiyoomi’s rim. Atsumu curses himself mentally. He’s close to making himself come without even fucking Kiyoomi. He should stop playing.
Atsumu presses the tip of his cock against Kiyoomi’s rim, feeling another spasm from Kiyoomi’s body under him. Atsumu holds his breath, pushing in slowly, just a few inches. It’s tight. So tight Atsumu hisses through it, before he stills over Kiyoomi. Atsumu’s body is taut. He needs a minute or he’ll explode on the spot. Atsumu can’t possibly thrust all the way in, he’d—
“Thought you were gonna ruin me.”
Fuck. Atsumu almost comes. His entire body is seized with a violent shudder from his suppressed orgasm.
Kiyoomi, awake, is craning his neck so he can look back at Atsumu, stealing a glance from the corner of his eyes. It doesn’t look like he wants to move from where he’s sunk into the mattress, though. Kiyoomi’s voice is rough with sleep. His gaze burning, ready to consume Atsumu.
“Ya were awake?” Atsumu gasps.
He’s out of breath like he just came back from the morning jog he said he wouldn’t go on.
Kiyoomi doesn’t smirk but Atsumu can hear it in his voice when he says: “Not really. Fell back asleep sometime when you were slobbering on my ass. Felt nice.”
“Ya little shit, just—”
Kiyoomi cuts Atsumu short, tightening up around the tip of his cock without mercy. Atsumu chokes on his own spit. At least the diversion and shock reined Atsumu in enough for him not to tip over the edge so easily anymore but Kiyoomi can’t know. All Atsumu is willing to give him is a good dicking-down. One that’s going to make him pass back out.
Atsumu leans over his lover, a hand threading through Kiyoomi’s curls and tugging back, a bit on the harsh side.
“Morning, sweetheart,” Atsumu says, lips pressed against Kiyoomi’s jaw… Before he punctuates the words with a sharp thrust.
Atsumu’s hips snap against Kiyoomi’s ass, pushing his body up the mattress and making Kiyoomi scramble for purchase. The headboard creaks when Kiyoomi holds onto it while Atsumu fucks into him, burying himself deeper with each roll of his hips. It doesn’t take long to fit all the way in. Kiyoomi is loose enough. The muscles in his back are working, flexing as he wakes up fully and takes Atsumu’s punishing pace. But his entire body was too warm and pliant from sleep to get stressed now or for Kiyoomi to hurt.
And if Atsumu is sure of one thing, it’s that Kiyoomi would be vocal about it now that he’s conscious. They can trust each other with it so Atsumu doesn’t hold back.
He only slows down with the rough pace because he wants to indulge a little longer. Atsumu feels pent-up and wired enough for his orgasm to take him by surprise if he’s not careful.
His thrusts turn into a deep, slow grind that has him curling over Kiyoomi’s body completely. Atsumu grabs Kiyoomi’s jaw, trying to press a kiss to his mouth but the angle is disastrous and Kiyoomi isn’t done being a little shit: “I must have fallen asleep longer than I thought if you had the time to brush your teeth between eating me out and fucking me raw.”
“I really fucking thought the mindful little treat would help ya wakin’ up all nice and charmin’,” Atsumu bites back but he’s grinning wider than Kiyoomi already is.
Atsumu rolls his hips in a circular motion, touching Kiyoomi so deep Kiyoomi has to close his eyes and grit his teeth.
“C’mon. Let me hear ya if I can’t kiss you,” Atsumu says, licking along Kiyoomi’s earshell, nipping at the sensitive skin.
“Shit,” Kiyoomi groans, burying his face into the pillow under him.
Atsumu can feel Kiyoomi push against the headboard to suck Atsumu in deeper. For all his big talk, he craves nothing more than to feel Atsumu. It drives him crazy. Atsumu wraps an arm around Kiyoomi’s waist, pulling him on all-four as Atsumu kneels behind him.
He manages not to slip out of Kiyoomi while doing so but Kiyoomi seems hellbent on keeping his face hidden in the pillow so only his ass remains up in the air. It’s fine with Atsumu. The arch it gives Kiyoomi’s back when it curves like this is all too sexy to complain about. It makes it perfect for Atsumu to watch himself sink into him and it brings out the dimples at the small of Kiyoomi’s back. The ones that made Atsumu come in four seconds the first time he saw them.
Not that he’s going to hold much longer than four seconds in this situation. He takes a second to breathe.
“Promise you’ll give me a kiss after I’ve brushed my teeth.”
“Finish what you started and maybe I will,” Kiyoomi says, nails digging into the sheets.
Atsumu has indeed stopped moving somewhere along the way but Kiyoomi’s words make him snap out of it.
“Say it, Kiyoomi.”
Atsumu thrusts all the way in slowly then stills again when he’s buried to the hilt.
“Atsumu.”
“Say yer dyin’ to kiss me and I’ll give it to ya,” Atsumu says — pulling out at the same maddening pace — until the tip of his cock is the only thing stretching Kiyoomi open.
“You’re gonna be so sorry the next time my dick’s inside you,” Kiyoomi warns him, sounding smug enough for Atsumu to look forward to it instead of fearing it. “I’m dying to get a disgusting kiss from you. I’d beg for it if I didn’t know how weak you are to that. But I kinda hoped you’d fuck me long enough to make me c— humph, fuck!”
Atsumu punches the air out of him with a nasty, powerful thrust.
“Ya think playin’ it feisty is gonna save ya? What if yer the one sorry when my dick’s inside ya?” Atsumu says, although he’s reaching around Kiyoomi’s body to fist his hard, leaking cock.
They’re all bite, no barks, and so what? Atsumu would rather not let Kiyoomi get the last word in but he still prefers seeing him covered in his own cum rather than frustrated just so Atsumu can take the win in a battle of wits.
“Atsumu. Fuck, yeah. You’re gonna—”
Atsumu is going to make Kiyoomi come. He knows him by heart, knows how it plays out mostly every time. Today isn’t a morning where they surprise each other. Today is about indulging themselves and getting off together because it’s what they do best.
Atsumu resumes the fast, deep pace from earlier, jerking Kiyoomi off in tandem with his thrusts. He kisses his shoulder blades, trails open-mouth kisses everywhere he can reach. Tension builds at the base of Atsumu’s spine, warmth spreading from his stomach all the way down his thighs. Atsumu is close. Kiyoomi too.
He really wishes he could kiss him, but even if Kiyoomi was down with it, the position they’re in is too uncomfortable for it. Atsumu does the next best thing. Like he did when Kiyoomi was sleeping, Atsumu brings his fingers around to Kiyoomi’s lips. This time, he’s wide awake and there’s pure greed in the way Kiyoomi sucks on them.
“Oh god! Kiyoomi, shit.”
Atsumu moans against his nape, biting and sucking on a patch of skin that is sure to bruise as Atsumu loses himself in pleasure. His thrusts grow erratic, shallow. Kiyoomi grunts and goes stiff under him. Atsumu is too high to realize what it means but then Kiyoomi pushes back against Atsumu roughly, swallowing him whole and Atsumu’s orgasm is all too sudden.
Something warm trickles between his fingers and down his fist but he doesn’t even think of letting go of Kiyoomi’s dick. For a moment, all Atsumu can focus on is the onslaughts of pleasure hitting him in waves and the buzzing sound in his ears. It fades fast enough but Atsumu still feels disoriented when it’s time for him to catch his breath.
Kiyoomi flops onto the mattress under him with a groan, Atsumu crashing next to him, both their chests heaving.
“You sure ya were asleep through it?” Atsumu asks after a minute of silence. “It didn’t—”
“It didn’t hurt. I was out cold, I promise,” Kiyoomi says, moving so he can kiss Atsumu’s shoulder.
“Still ran yer mouth like I missed all yer sweet spots, though.”
Atsumu grins now that his concerns are wiped out.
“Go wash yours so I can get my fucking morning kiss.”
Kiyoomi’s jab comes with a pillow thrown in Atsumu’s face. Atsumu splutters as he sits into the bed. He looks at Kiyoomi over his shoulder. Kiyoomi is gorgeous, splayed there with cum splattered over his own chest.
“Omi… Ya really think I have a kink for ya beggin’?”
“Wanna find out sometime this afternoon?”
Kiyoomi arches an eyebrow as he asks, the corner of his mouth tugging into a mocking smirk.
“That’s gonna amount to a lot of exercise for people who said they were gonna lay low today,” Atsumu says.
“Your math is wrong. And we can be laying low if we get somewhere on the floor I guess.”
Atsumu snorts. Damn, he needs to gargle some toothpaste right this fucking instant because he’s spending the next hour making out with his outrageous boyfriend.
“So I have to brush my teeth before we kiss but yer okay bein’ nasty on the kitchen floor,” Atsumu says as he strides toward the bathroom.
“I’m making you vacuum it first. It’s the first thing I’ll be begging for, in fact,” Kiyoomi tells him from the bed.
“Shit, Omi. Yer gonna make me hard again.”
“Oh I’m fucking planning on it, Miya.”
Yeah, Atsumu can see himself gag on his toothbrush if Sakusa Kiyoomi is ready to beg for him.
