Work Text:

"Meian, please introduce our newest member to the rowdy bunch." Foster dismisses the two men after exchanging a quick handshake with Kiyoomi.

"Sure thing, Coach." Meian nods, ushering Kiyoomi out the office door. "I must warn you, Foster wasn't lying when he said they're rowdy."

Kiyoomi scoffs. "I'm aware of who my new teammates are. I think I'm prepared."

"If you say so." Meian laughs.

Kiyoomi stills himself with a breath. He prepared for this. He's aware he'll be the only non-alpha, save for Hinata, on the team. He's prepared for the ridicule, the criticism, the backhanded compliments from reporters after a game.

He's used to it, after all. He's only been like this entire fucking life. He knows what to expect as a late bloomer. Still, he takes a breath before walking through the gymnasium doors.

"Quiet down!" Meian uses his alpha voice on the noisy athletes, successfully silencing them. "Now, behave. We have a new member. Sakusa Kiyoomi, welcome to the team."

In front of Kiyoomi stands six men, four of which he's already been acquainted with at some point or another. He immediately gravitates toward the omega, smelling Hinata's faint orange scent, even through all the alphas'.

"I'm happy to be here." Kiyoomi says, confidence dripping from his voice. He belongs here, and he knows it.

Everything goes on without a hitch; everyone introduces themselves, and Kiyoomi even indulges in shaking each player's hand. It was all going well, until a certain blond approached.

"Miya Atsumu." He smirks, sending heat into Kiyoomi's belly.

What the fuck?

Atsumu's scent is overpowering, making the air feel thick.

"God, would you stop fucking scenting the place? How's about some common decency?" Kiyoomi spits.

Atsumu laughs. It's awkward and stiff. "What d'ya mean?" He glances around at the other men.

"This place fucking reeks of you, Miya. It's making me sick."

"Omi-kun, I'm wearin' patches." Atsumu blinks.

It's getting warmer by the second. Kiyoomi feels lightheaded as he steps away from the blond. "I'm going to excuse myself, I don't feel too well."

"Sakusa, are you okay?" Meian puts a hand on his shoulder, but it only makes it worse.

"I'm fine. Just– fuck."

A stabbing pain in his abdomen, and… did he just piss himself?

"Shit." Meian mutters.

Kiyoomi looks down to find a growing wet spot by his crotch. Arousal pools in his gut as he sways on his feet. All he can smell is Atsumu; freshly rained terrain mixed with… peaches? He wants more.

"Miya." Kiyoomi mumbles, stepping forward, eyes trained on the alpha's neck. He wants—needs—those patches off.

"Sakusa-san, listen to me." Meian says sternly, holding the man back by the shoulder. "I think you're–"

"Ya bloomed for me." Atsumu whispers.

"Miya." Kiyoomi whines, leaning closer to the blond, desperately wanting to be engulfed by his scent.

"Everybody, out!" Meian commands, resulting in every last man filing out the doors quicker than Kiyoomi can process.

He's not really paying attention, to be honest. He just wants to be closer to Atsumu.

"Atsumu, that includes you." Meian growls.

"No, no." Atsumu raises his hands in surrender. Kiyoomi preens, pushing his head forward until the crown of his head touches the blond's palm. "It's okay, Meian. I got him."

"Atsumu." Meian warns. "This could be dangerous. He's a newly presented omega, and you're an unmated alpha."

"No, really. It's okay, I'm not– I don't feel out of it. I just wanna take care of 'im. Please." Atsumu massages Kiyoomi's scalp with his fingertips.

Meian sighs. "Sakusa-san. Is there anyone we can call for you?"

"Need Atsumu." He whines, nudging into Atsumu's hand, desperate for more touch.

Meian hesitantly let's go, letting Kiyoomi fall into the setter's chest. He hums, wrapping his arms around Atsumu's neck.

"I need to go speak to Foster. Get practice postponed. You sure you're okay, Atsumu?"

"I'm good, Meian. I've been on those rut suppressants for a while, so." He shrugs. "Should be fine."

"Alright." Meian sighs. "Take care of him."

Kiyoomi paws uselessly at Atsumu's scent patch, wanting to smell more of the alpha. Atsumu chuckles, the sound sending heat to Kiyoomi's chest. He peels off the patch, and Kiyoomi immediately buries his face into the gland.

"Let's go sit down, yeah?" Atsumu suggests, leading them to the benches. "I'd offer ya a change of pants, but I don't think ya wanna get off me."

"Mm-mm." Kiyoomi shakes his head against Atsumu's neck.

He's pulled onto the setter's lap with little resistance, falling comfortably into his chest. He can't seem to get enough of the alpha's scent. He just wants more, more–

"More." He whines.

Atsumu huffs softly, excreting calming pheromones from his scent glands. "I gotcha."

"More, Tsumu." Kiyoomi pouts, pulling back to make eye contact with the blond.

"How's about this? I can take my shirt off, so ya can be skin-on-skin with me, but no funny business, alright?"

Kiyoomi nods urgently, helping Atsumu tug his jersey over his head. He relaxes immediately, feeling the alpha hold him tight. He feels safe.

"Alpha." He hums.

"Good, omega." Atsumu coos, rubbing his hand up Kiyoomi's back. "Never thought I'd see the day ya presented as an omega, though."

"Shut up." Kiyoomi groans, wrapping his legs around Atsumu's waist. Annoyed as he is, he can't help but want to be closer.

"Funny omega." Atsumu laughs. "If ya wanna sleep, ya can go ahead. I know presenting can be real tiresome on the body."

Kiyoomi doesn't need to be told twice, his eyes falling shut as he's lulled to sleep by the gentle rise and fall of his alpha's chest.

 

 

"Omi-kun."

Kiyoomi's head rings.

"C'mon, Omi, wake up."

"Shut the fuck up." Kiyoomi groans, burying his face deeper into Atsumu's chest.

Atsumu chuckles, his chest knocking Kiyoomi's head. "It's late. I wanna getcha home."

"Fine." Kiyoomi grumbles, only because he'd love more than anything to be in his own bed right now. "What the fuck?"

There's stickiness between his legs and a stain over his crotch.

"Oh, God, is that fucking slick?"

"It's normal, Omi. Nothin' to be embarrassed about." Atsumu helps him to his feet, trying not to laugh when Kiyoomi grimaces.

"This is humiliating." He mutters.

"It ain't that bad. We've all been there."

"Yeah, well, I fucking bloomed my first day on the team. Didn't even get to fucking play."

Atsumu helps Kiyoomi into his car, making sure he's buckled up before getting into the driver's side.

"No one's gonna be a dick about it, if that's what you're worried about."

"Whatever." Kiyoomi mutters.

He's not sure exactly what he's worried about. Maybe it's the fact that he'll be the only omega of his parents' children. Maybe it's being an omega in an alpha-dominated sport. Maybe it's the fact he bloomed for Miya fucking Atsumu.

There's a lot to be worried about, okay?

"Thanks." Kiyoomi lets himself out of the car as Atsumu pulls up to his apartment building. "See you."

"Hey, wait." Atsumu tumbles out the car. "I'm stayin' the night."

"Excuse me?"

"Omi, it's really hard to be alone after ya've bloomed. It's best to be with family. Or, in your case, the alpha ya bloomed for."

Kiyoomi blinks. "I feel fine, Miya."

"Yeah, ya might be okay right now, but later."

"Stop worrying, I'll survive."

"Omi, do ya really not know how this works?"

"Oh, I'm sorry, this is only my first time blooming. Forgive me for not being educated." He remarks, turning his back on the alpha. He treks into his apartment building, ignoring the loud blond behind him.

"Omi, bloomin' works similar to heats. It comes in waves." Atsumu chases after him. "I'll give ya an hour before ya become miserable alone, cryin' for your alpha."

"You're not my alpha." Kiyoomi scoffs, unlocking his apartment.

"Yeah, well, I'm the alpha ya bloomed for, so." Atsumu follows him, closing the door behind him. "I'm not tryna be a nuisance, Omi-kun. I just wanna help. I know how bad Hinata's bloomin' was from experience."

"You were there?"

"We kept in touch after our first game against each other. I was with him when it happened."

Kiyoomi laughs. "Did he bloom for you too?"

"Tobio-kun, actually."

"Huh." Kiyoomi pauses. "Saw that coming, to be honest. Now, really, if you'd just– ugh."

"What's wrong?"

Kiyoomi's hand flies up to his face, covering his mouth and nose. "God, your scent is just overpowering."

"That's another wave, Omi."

"Please leave." Kiyoomi says sternly. He clamps his nose shut, even though his inner omega begs for the alpha's scent.

"I ain't leavin', Omi. Let me take care of ya. Lemme be a good alpha."

That's all it takes for Kiyoomi's inner omega to break loose, stumbling forward into the alpha's embrace.

"That's it, Omi, you're good. I gotcha." Atsumu soothes, guiding them down onto the couch.

"Hurts, Atsumu."

"What hurts?"

"Here." Kiyoomi presses Atsumu's hand against his abdomen. "Aches."

"I know, Omi, it ain't fun. You're safe, though, okay?"

"Wanna feel you." Kiyoomi whines, lifting the hem of his shirt.

With a chuckle, Atsumu follows, taking his own shirt off. Kiyoomi is quick to press his bare skin against Atsumu's, feeling relief bubble over.

"Alpha." He pants.

"Good, omega. It's okay."

"Fuck." Kiyoomi groans. "Just– ignore what I said earlier."

"Hmm?"

"Stay, alpha. Please."

Atsumu smiles down at the omega on his chest. "I ain't goin' anywhere. Sleep, now, omega."

Kiyoomi's eyes easily flutter shut. He feels at peace on the alpha's chest. The ache in his belly is tolerable with the strong smell of rain and peaches filling the air.

Perhaps having Atsumu as an alpha wouldn't be the worst thing in the world.
