Work Text:
in a world where secondary genders meant everything, atsumu had prided himself on not caring about such outdated stereotypes. he liked being an alpha, both him and his twin had found out about their secondary genders on their 12th birthday.
their parents were proud, neighbours had come to celebrate and he remembers not even caring about the meaning, he was just happy to have attention on him all day. his brother wasn’t much different, osamu loved volleyball and then decided to open onigiri miya.
when he had expressed his passion for cooking, a lot of people found it strange. they expected a strong alpha like him to go pro just like his twin which is why atsumu hated stereotypes. his brother was the best damn chef he’s ever known.
another reason why he despises stereotypes is because of sakusa kiyoomi.
another taller alpha on his team, someone who he does consider his best friend but he hates it. everywhere they go, people are always trying to set the man up with an omega or some unsuspecting beta.
all that would be fine if it was his choice but sakusa rarely even likes to be around his own friends, why would anyone think the man had any interest in dating?
why would anyone assume he only wanted to be with an omega or a beta? what if sakusa liked alphas?
that could very well be a possibility and one atsumu likes to hold onto.
he remembers sakusa being so upset after his visit to his family over their short winter break just a few weeks ago. his father had insisted he meet with potential marriage partners and he had never seen sakusa cry like that in his life.
they spent everyday on facetime until he could get an early flight back to their shared apartment.
atsumu whines softly as he lays his head on the cool countertop of onigiri miya. it’s closing time now so there are only a few customers and osamu is making him his favourite.
“as much as i enjoy seeing you suffer, this is pathetic tsum” osamu sighs, “it’s pathetic actually”
“shut up, i’m experiencing horrible chest pains so can’t you be nicer to me?” atsumu pouts but he’s staring blankly at the wall where the menu is displayed. he should probably order extra to take home for sakusa.
“i can but i don’t feel like it” osamu grins, “here, sit up properly”
he places the food in front of his annoying older brother and gets him a drink.
“is this how you felt before you and suna got together?” atsumu asks, shoulders slumped even as he bites into his food.
“and how do you feel?” osamu asks because even if he pretends not to care, he does. he imagines atsumu’s scent would probably be sour right now if he was an omega and he wasn’t wearing scent blockers. it’s a little funny to think about but he knows it’s not the time to make fun of him.
“helpless” atsumu groans, “like i want to lock him up and keep him away from everyone and everything that bothers him”
“okay weirdo” osamu frowns but he gets it. he just doesn’t want to admit it.
“i think i might be in love with him” atsumu admits quietly, “no… i definitely am in love with him”
oh..
osamu is slightly taken aback by that. he knew atsumu had feelings for sakusa, anyone with a brain that wasn’t him or sakusa could tell but he didn’t think it was this bad.
it also didn’t help that atsumu’s rut was due any day now because he was always extra emotional and temperamental those days.
“atsumu, sitting here and moping isn’t going to help you at all” osamu pats his shoulder
“it is” atsumu pouts again, “you make me food”
and yeah, he definitely had it bad.
atsumu arrives home to a quiet apartment. he knows sakusa is either reading or already sleeping since practice ran later than usual.
he places the food on the counter, all of sakusa’s favourites from onigiri miya and grabs a water out the fridge.
“omi?” he calls and he hears a soft grunt and then shuffling.
“you’re late” sakusa says dryly but his eyes light up when he sees the containers on the kitchen counter.
“i went to see samu, these are for you” he smiles and sakusa grins, it’s small but atsumu spots it anyway and his heart does a somersault and he suddenly feels sick.
he groans, downing his water before reaching for another.
“is everything okay?” sakusa asks after he swallows because unlike atsumu, sakusa has manners and doesn’t talk with his mouth full.
“yeah, i’m fin—”
before he can finish, a cool hand is placed against his forehead.
that’s the other thing. sakusa doesn’t touch anyone. it’s super rare that he does with their friends. he likes his personal space, prefers things to stay one way or he’ll lose it. it doesn’t help that he has mysophobia which atsumu has always respected and understood but sakusa always touches him.
a headpat, a flick on the forehead, a pat on the back, squeezing his hand.. sakusa seems to like gravitating towards him and it confuses his poor little heart because what does it all even mean?
“you’re burning up” sakusa frowns, “and i know you’re not sick, we’ve had our shots just yesterday”
“your rut” he says after a moment, “you should be starting any day now.. are you okay?”
“yes i’m okay” atsumu says, “i’ve stocked up on everything i need and i reminded coach yesterday about it”
“i’ll stay home.. in my room” sakusa says and his hand hasn’t moved away yet.
“wha— omi, that’s not necessary” atsumu feels his cheeks heating up but he can easily blame it on his slight fever.
“you might need me” sakusa says and he can tell there’s no point in arguing because sakusa is as stubborn as he is.
“okay” atsumu nods dumbly and sakusa laughs softly, “thank you omi”
sakusa pats his head and goes to get a bottle of water.
the rest of the night is uneventful, he feels too irritated to do anything so he takes a long cold shower and lays on his bed in a starfish position. he knows his rut is rapidly approaching because it’s too hot, way too hot and it’s still winter.
he’s pretty sure it was even snowing early so why is his room so fucking hot? he has the fan on and he’s just in boxers but it’s not helping.
his skin feels weird and his starting to get hard and he usually handles it just fine. he has toys for these things but he just feels like crying because nothing feels right.
he over over, groaning. he reaches for his drawer, pulling a bottle of lube out. his hand is hot to the touch so it feels amazing on his cock but it’s just not enough. he feels … empty.
his eyes widen at that realisation. he’s never felt this way during any of his ruts before and his fighting against the hazy feeling in his head before he loses himself in his rut for the next 3 days.
he wants..
he wants … no he needs sakusa.
he hears himself crying, gripping his sheets hard enough to tear.
“omi” it sounds pathetic even to himself but he can’t help it. he’s never felt this overwhelmed in his life.
sakusa is at his side immediately. he doesn’t comment on the fact that atsumu is now naked and curled up on his side, he doesn’t even make fun of him for it.
“atsumu?” sakusa reaches out gently, rubbing his shoulder. he’s composed, focused solely on making sure atsumu is okay.
“omi… please” atsumu begs but even he doesn’t know what the fuck he wants. it’s all messed up, this isn’t how he planned to confess but he feels so empty and everything hurts.
“talk to me tsumu” sakusa says, “i’m right here”
“i.. i’m sorry” atsumu is crying again, “this isn’t how i wanted it to go”
sakusa isn’t stupid. he might’ve been oblivious but he tried to convince himself that it was one sided. he didn’t think someone as bright and easy going as atsumu would want him that way.
atsumu could have anyone he wanted. anyone at all.
“shhh it’s okay, don’t cry baby” sakusa guides him onto his back. his calm, even as his heart is racing and beating so fast it hurts. he needs to stay calm so atsumu doesn’t freak out. “there we go sweetheart, it’s alright”
atsumu slowly calms down, it’s weird because he’s an alpha and he’s conditioned to attack another alpha in moments like this but it’s clear as day his alpha trusts sakusa just as much as he does. his growl is soft and not threatening at all.
sakusa helps him drink water and it clears up the do just a little. he hasn’t completely lost himself yet, this gives him a moment to gather his thoughts. to focus on sakusa and the way his holding his hand.
“there you are” sakusa chuckles, using a wet cloth nearby to wipe his face.
“i’m embarrassed” atsumu admits
“because you confessed with your dick out?” sakusa teases and atsumu blushes hard, spluttering.
“i knew i fell for an idiot but this is a new one, don’t you think?” sakusa takes his hand and kisses it.
“you… fell for me?” atsumu eyes light up, his brain still feels fuzzy but he’s trying his best to stay in the moment with sakusa.
“in high school” he admits and atsumu has never been this happy in all his life and he’s always happy.
their kiss is soft, passionate but nothing like the movies make it out to be. it’s real, it’s perfect and it’s everything atsumu has ever wanted.
“i’ll help you” sakusa says softly, “we’ll need a lot of lube though”
“okay..” atsumu nods, “i trust you omi”
though atsumu knows his body isn’t going to resist sakusa, alpha or not.
sakusa isn’t a virgin, neither of them are but this moment feels like it. his hands tremble as he holds atusmu’s waist. he usually keeps gloves nearby when he’s doing this but he finds himself wanting to feel every part of atsumu.
atsumu whimpers, teeth clenching as sakusa slowly pushes his middle finger into him. there’s little resistance which surprises them both. atsumu hasn’t had anyone touch him there before but he’s never been opposed to it. this is technically the first time anyone will fuck him and he’s giddy, his face flushed beautifully.
“so good baby, you’re doing so good” sakusa holds his waist, kissing his lower back. atsumu feels like he’s on cloud nine.
“i want to be good for you omi” atsumu moans, gripping the sheets harder. his knees feel like they’ll give out soon but he’s determined to be good for sakusa.
“i know gorgeous” sakusa smiles, “i’ll reward you real good”
atsumu grins, biting his lip as he presses his cheek against his pillow.
it’s soft and warm inside atsumu, his walls grip sakusa’s fingers like they don’t want him to stop and if sakusa wasn’t so impatient right now, he’d be happy to have atsumu crying on his fingers all night.
he’d come back to that when it wasn’t anyone’s rut.
he grabs more lube and removes his pants, making sure he still touches some part of atsumu because he can tell he’s slipping away because his pretty eyes are so wide and blown out as if he’d taken something he wasn’t supposed to.
seeing him like this is very intimate, something sakusa doesn’t take for granted. he knows atsumu doesn’t like being seen when it’s time for his rut, they’ve known each other for many years now, he’s seen all sides to the fake blonde but never like this and he wants to be the only one to ever see atsumu this way.
for as long as atsumu will have him.
he hopes it’s forever.
“omi omi please” atsumu begs, arching his back like he’s more than happy to present for sakusa even as an alpha himself. it’s beautiful and so fucking hot.
“i know baby” he grips his cock, groaning at finally getting some sort of friction but it’s not enough.
he’s gentle, slow as he pushes into atsumu. it’s a very tight fit but it’s so perfect he thinks he might just tear up from how good this feels.
atsumu is no better as he cries out, back arching even more, in a way he didn’t think was possible. his thick thighs tremble as he feels himself being filled up to the brim.
it feels so deep like it’s in his throat and he can’t breathe. it’s all too much and not enough at the same time. he’s never felt this overwhelmed in his life.
“baby you need to breathe or you’ll pass out” sakusa says and he’s surprised at how clear his voice is because he’s definitely not doing any better himself.
his cock feels like it’s coming home. atsumu grips him so tight and hugs his cock like he’s been waiting for this for so long and he probably has, sakusa knows he has.
“you’re so good” he leans down, pressing gentle kisses down atsumu’s back. it should be disgusting with how hot and sticky his skin is but sakusa loves it. he wants to be even closer if it’s possible so he leans his full weight over atsumu like a safety blanket and begins to fuck the love of his life like he’s always wanted to.
his grip on atsumu’s waist hurts, it’s going to leave marks and atsumu is reeling from it. he wants those marks imprinted on his skin forever, he wants people to see it and know sakusa is his and he is sakusa’s.
he isn’t shy when he moans louder, begging sakusa to keep going even after he cums. his ruts are always intense but never this much. he feels like he’s going to lose his mind if he hasn’t already.
“there!” he cries out, eyes crossing. his drool has made his favourite pillow damp and he feels sticky everywhere but he can’t think of anything other than sakusa’s dick inside him.
the man was not long long but thick and it hit the perfect spots inside atsumu that he didn’t know existed.
the bed creaks with the weight of two massive volleyball players but he doesn’t care. he can buy a new bed, there’s only one sakusa kiyoomi and he wants the man to break him.
as if he can read atsumu’s mind, he picks up the pace. his stamina was no joke and he showed no signs of slowing down, fucking atsumu faster and harder like he needed atsumu to feel him for days.
hours pass, atsumu has long passed out after sakusa cleaned them up. they’re in sakusa’s room, the sheets are cool to the touch and he feels like he’s floating.
“you still with me?” sakusa asks, rubbing his back gently.
“hm” atsumu sighs happily, “i am”
“rest for a little and then we can get something to eat” sakusa kisses his shoulder, “i’ll sort your bed out”
sakusa kiyoomi is just too perfect and atsumu wants to keep him forever.
“thank you omi” he yawns, smiling.
sakusa just grins and pulls the sheets up over his waist.
