Notes:

For SakuAtsu Omegaverse Week 2023!

Trope: Blooming AU: Roommates

This was hell.

It had to be.

He was around Miya at practice damn near all week, but it's being made to share a hotel room that does him in?

Seriously?

Okay, to be fair, practice included professional grad scent patches from presentation onward, but this couldn't seriously be the first time he was smelling Atsumu's scent.

"Omi-Omi?" Atsumu frowns in concern now instead of the cocky smirk he had a minute ago when getting out of the shower and letting his scent out before the fan could suck it away. "Ya good?"

He was not.

He absolutely was not.

The second the setter's star anise and pomegranate scent followed him out of the bathroom, Sakusa almost doubled over from the force of it.

He's panting as he looks up at the omega with hazy eyes, mahogany trying to leak out of his own patches. "Get out, Miya. Now ."

Atsumu scoffs, thinking Sakusa's just being a dick. "What the fuck gives ya the right-"

"I'm serious, Miya." Sakusa snaps, fangs starting to drop and making Atsumu freeze. "Get out. Go hide in Hinata's room or a bathroom or something, but you need to get the fuck out."

Atsumu just stands there stunned as he takes in the alpha's appearance and Sakusa starts eyeing the door himself as he sees the pieces start falling into place with a shit-eating grin.

"Omi-Omi, are you by chance bloomin' for me?" Atsumu smirks as he goes back to drying his hair and ruffling his scent around more.

"Fuck off, Miya." Sakusa snarls, eyes darker than usual as his pupils overtake his irises and he has to swallow the drool trying to collect in his mouth. "I'm trying to not be a knothead. Get the hell out." His voice is starting to take on a growling quality.

He's shocked speechless when he watches pupils overtake gold and starts to smell blueberry muffins.

"Flirtin' with ya fer years an' all I had ta do fer a possible in was takin’ a shower, huh?" Atsumu smirks, still allowing the alpha his space no matter how much he wants to get closer. "Shoulda known the way ta yer heart was soap."

Sakusa blinks, raging hormones seemingly screeching to a halt with the rest of him as he tries to process what he's just heard. "You-…You were flirting with me? …For years?!"

"Since high school, yeah." Atsumu shrugs, giving the spiker space as he walks around him to get the toothbrush he had come out for in the first place. "Thanks fer finally noticin'."

Another blink as his mind races to shove every possible instance to the forefront. He also recalls several locker room conversations. "…In my defense, I built my entire image on 'Fuck off' and you actively brag about yours being 'Fuck me'."

Atsumu snorts, shaking his head. "Okay, fair enough. Was also a partial tactic change of 'fingers crossed he either gets jealous or curious'." Teasing eyes turn back to Sakusa. "Any chance I can spark the second option?" He asks, giving the alpha the opening to properly tell him to fuck off if he still wants to.

Sakusa makes a face, panting as he tries to think this through. "…We have games tomorrow. We can't afford to have both of us out. Especially not our setter."

Atsumu scowls at the wall. "Think ya can keep yer alpha in line long enough fer me ta brush my teeth an' think?"

Sakusa looks down at where he's already clawing the carpet with a scowl of his own. "Close the door and maybe I can hold myself back. Take your phone with you though in case you have to call the others to get you because I'm probably going to jump you the second you're out-the mating scent is not helping!" The alpha growls, reaching over to toss Atsumu his phone on his way past.

Atsumu just smirks, thoroughly amused by the usually prickly but otherwise stoic alpha being so close to losing his cool even if it was hopefully going to end at the expense of his walking privileges. "Will do fer the backup, yer outta luck on the scent." He snickers, closing the bathroom door with a yelp when a snarl is suddenly much closer. "Okay! Sorry! Damn! I'll stop pokin' the bear! Just don't go breakin' shit!"

There's a huff on the other side of the door, but Sakusa does in fact move away leaving Atsumu to sigh and start texting their coach and captain for advice as he brushes his teeth. It takes exactly one text and one confirmation of the situation for Forster to call him to start figuring this out and all Atsumu can do is sigh around the toothpaste in his mouth as he's scolded for not bringing new patches into the bathroom with him for when he was done.

"Yes, - spit - coach. Not my brightest moment, but I'm used ta roomin' with Sho-kun,- gargle - an' scoldin' me isn't gonna fix the problem now so do I need ta call the others or can I finally stop pinin'?" Atsumu finally huffs.

{ You ?! He's just as bad! You're both just drunk whenever he admits it and I'd almost rather ask Bokuto about Akaashi during those points." Foster scoffs with a tapping sound in the back. "That's what I'm checking now though. Just waiting for the other coaches and an official to respond. You're so lucky this is a charity tournament, maybe we can switch first bracket days with another team. …You're in luck. Raijin was out at team dinner and one of their blockers and their libero are also sick of you two. Do I want to know where their blocker got blackmail?} Foster sighs with the same tone as when his pieces of the monster generation start giving him new grey hairs. {Should the end of the week be enough?} The beta asks.

"Uhhh…" Atsumu hums, checking his shower bag and pulling out his suppressant bottle, popping one as he counts. "Yeah, we'll be good. Ruts are usually like three days an' I'll make sure he stays hydrated. Think someone can drop food an' drink off?"

{I'll send Meian around.} The coach sighs. {Use protection and all that. I better not hear about any of it.}

"Shit, uhhh, oh thank god. Yup! See ya Friday." Atsumu grins, not giving Foster a chance before he's hanging up to yell through the door. "Turn off yer phone! Suna and Komori blackmailed their coach into switchin' game days so I'm sure he's already sendin' a paragraph. …You did also originally tell me ta leave. Do ya actually want that orrrr?"

"Get out here, Miya," Sakusa growls from right outside the door.

"Meian's droppin' off food an' shit later. Can ya behave fer me ta get it when he does?" There's teasing in the blonde's voice.

Sakusa huffs, muttering something Atsumu can't hear, but both know how unpredictable rutting alphas are once they properly fall into a rut. "I'll try ."

"All I ask." Atsumu chuckles, finally unlocking the door and starting to open it. "Yer lucky I always pack condoms. My birth control should be fine, but I'm sure ya'll-" He's cut off with a yelp when he barely gets the door open before Sakusa grabs him and he's suddenly bouncing on one of the beds. "Omi!"

"So you're saying no condom is okay too?" Sakusa growls as he starts getting his shirt back off and making Atsumu's mouth run dry with the sight before he's fully blushing as the words sink in.

"Ya don't care about the mess?" Atsumu asks, not wanting Sakusa to hate him after this.

"You heard Coach." Sakusa smirks, a growl slipping further into his voice. "There's a reason he'd prefer Bokuto."

Atsumu will deny the desperate whine that rips from his throat until his dying day, but for now, he just grabs dark curls the second they're in reach to pull Sakusa into a kiss loaded with years of pining. "I shoulda asked fer details." He pants with a laugh when they break for air. "Care ta demonstrate, Alpha~ "

The snarl that rips from Sakusa makes Atsumu keen before he's pulled into another fierce kiss that makes the setter's head spin as the alpha rips his own scent patches off. Somehow the fact that he made Sakusa bloom didn't connect for him that the alpha's scent would do the same to him when he took the suppressant. It was definitely a waste of a pill because he moans as he falls hard and fast to the scent of oranges, fresh linen, and mahogany that quickly dominates his senses.

"Omi-Omi~" Atsumu slurs when the alpha starts moving down his neck. "Fuck, yer scent. Been hidin' this all this time. Fuckin' criminal offense." He manages to joke before moaning then the spiker starts sucking a hickey over his scent gland. He knows there's something he should probably ask about that, but it's completely escaping him with the rest of his logical thought.

His joke manages to get an eye-roll, but otherwise, Sakusa is entirely more focused on the sounds he's pulling from the omega and what others he could possibly get as the setter's scent reaches dizzying strength that makes his alpha howl.

"Smell amazing," Sakusa mumbles into the blonde's neck before he starts biting and sucking his way down the omega's strong chest to bite at a nipple and draw out a surprised moan. "Bet you taste like fucking heaven."

Atsumu's face is burning, wondering where this side came from in the normally prickly spiker. "Omiiii!"

Sakusa's smirk is hidden by the angle, but he knows exactly what he's doing as he plays with a now wet and sore nipple with his thumb and pointer finger. "Look at you, Miya. So pretty and strong." He squeezes as much of the omega's pec as he can to watch the blonde's blush try to reach his fingers. "I could try to break you and you'd be able to take it no problem, couldn't you?" A dark chuckle earns a whine that makes him look up to see Atsumu covering his face in embarrassment.

Well, that won't do.

Sakusa gathers the setter's hands in his with a warning growl when he sees his eyes closed. "Look at me, Miya." A head shake makes Sakusa roll his eyes before smirking again and letting some growl enter his voice now. "'Tsumu~"

Atsumu's eyes snap open in surprise before his face gets somehow hotter at the hunger in Sakusa's eyes and he whines with need. "Omi…"

"There you are." Sakusa hums, leaning forward to devour Atsumu with another mind-melting kiss. "Telling you to shut up for years and all I had to do is kiss you, huh?" The spiker teases, snickering at the setter's offended noise. "Hmm, good to know."

The implications make Atsumu try to hide again, but Sakusa still has a hold of his hands that he moves to be pinned against his lower stomach so he has nowhere to hide. "Omi!"

"Nope. Waited this long, I want to see you." Sakusa smirks as he leans in for another kiss before going back down to torturing the blonde's nipples and fighting his own boxers off with his free hand, thankful for the core strength he's developed over the years so he's not having to rest all his weight on Atsumu to do it. Sitting up to throw them to the side tells Sakusa the exact moment Atsumu sees what's about to go inside him based on the needy moan and hungry eyes trained on not his face when he looks back up.

"Omi-Omi…" Atsumu breathes before reminding Sakusa he's an athlete too as the spiker suddenly finds himself on his back with a very enthusiastic mouth suddenly on his dick, tonguing at his slit and making him throw his head back with a shout.

"Fuck, 'Tsumu!" Sakusa growls, his alpha snapping about losing control of the situation but neither he nor his dick has any complaints. "Knew that mouth had to be good for something."

Atsumu just flips him off as he works on seeing how much he can get in his mouth, gagging about three-quarters of the way down and pulling back to adjust and try again. He lets a hand slip under him to start collecting slick and opening himself up.

Sakusa notices and agrees with his alpha that he should be the only one bringing the omega pleasure as he flips them again when Atsumu comes up for air so Atsumu can still suck his dick, but he can also get at the slick already dripping from the setter's hole.

"Fuck, look at you." Sakusa hums, leaning up to bite a toned ass cheek and hear Atsumu yelp before burying his tongue between them to hear and feel him moan.

He finds himself agreeing when a taste matching the omega's scent explodes across his tongue and he lets out a deep groan as he licks deeper, letting some slick drip down so he can use it to start stroking Atsumu's cock and make him gush more slick.

"Fuck, Omi~" Atsumu whines when he comes up for air. "Yer tongue."

Sakusa smirks, working a finger in as he pulls his face back to smack Atsumu's ass when he just sits there panting, smirking when it makes the omega moan. "You started this, no slacking." He huffs before diving back in.

Atsumu whines, squirming when Sakusa's fingers reach deeper as he licks inside and sucks at his rim like a starving man. "O-mi-Omi…" He keens before moaning again when his lack of action gets another smack on the ass to get him moving again. When those long fingers find his prostate, his brain fogs over with his own heat and he moans around the cock in his mouth, having to fight his brain cell to not just fall limp and let the alpha use him. He's almost annoyed with himself. He's never like this when he heat or rut shares, what the fuck?

When a third finger joins the other two in tormenting his prostate, all remaining thoughts leave his mind so he decides he'll blame it on making each other bloom and get the alpha back for it later.

In the meantime, Atsumu purrs proudly when he finally reaches the alpha's knot, swallowing around the tip he managed to work into his throat and only gagging a little when it makes Sakusa jerk his hips with a curse before he hollows his cheeks on the way back up to do it again.

Sakusa usually has better control of himself than this, but he might as well be drunk with what Atsumu's mouth and slick are doing to his head as manages to squeeze a fourth finger in just to hear the lewd squelching the setter's slick causes. It's not long though before his alpha starts bitching at him again to breed the omega, and Sakusa is having trouble finding any sort of reason to argue as he uses his long arms and bendy wrists to drag Atsumu off his cock by blonde hair, smirking at the whine he gets.

"What? Don't want fucked?" Sakusa teases, snickering when Atsumu almost falls off the bed in his scramble to present for his alpha, barely giving the spiker a chance to remove his fingers. "That's what I thought."

"Been picturin’ it since high school." Atsumu wheezes, flushing at how wrecked his voice sounds from sucking the alpha's stupidly big cock. "Fuckin' sue me."

"Think you added a word in there," Sakusa smirks as he licks the access slick off his fingers with a moan before plunging them back in for more slick in order to hear Atsumu moan and to lube up his cock with it. "But gladly."

"How-" Atsumu is cut off by a desperate moan as Sakusa starts to sink in. "How are ya still -fuck, Omi- still such a sarcastic asshole. "

"You're no angel." Sakusa scoffs, pushing in further to watch Atsumu grip the sheets.

"Fuck ya."

"Maybe later."

Atsumu's eyes widen at the prospect, opening his mouth to ask if the alpha is serious before moaning loudly when Sakusa takes advantage of his distracted state to thrust almost all the way in and fuck he's fucking big. "OMI!"

"Fuck, should've had you lay on your back." Sakusa groans as he works the last bit in and at least has the sense to wait a second. "Bet you look so pretty screaming my name. Gonna have to make you cry on my cock next round."

Atsumu whines, somehow forgetting that it wouldn't be just the one round as he squirms. "Omi-Omi, fuck, move, please. 'M ready, Omi-Omi, please"

Sakusa hums in fake consideration, having fun toying with the omega even as his alpha eggs him to get on with it when he leans over the setter to play with his apparently very sensitive nipples until Atsumu is squirming and begging.

"Omi! Omi-Omi, please, please, please! Move! Please! Fuck me! Fuck me, please! I'll do anythin', just please!" Atsumu eventually hiccups, close to crying from how badly he needs it.

Sakusa smirks wickedly. "Promise?"

"Yes, anythin', just pleA-AH!" Atsumu moans loudly when Sakusa finally pulls almost all the way out to slam back in and starts a hard, rough pace that makes his eyes cross. "OMI!"

"I'll hold you to that," Sakusa grunts as he leans back and crosses an arm across the setter's chest to make him sit on his cock so he can pound into him and hear the omega's cries with no way for him to hide. "Fuck. Tight."

"Omiiii~" Atsumu slurs, clinging to whatever parts of the alpha he can reach as he's fucked without mercy or chance of escape. He about cums on the spot when Sakusa's other arm reaches out to cover his throat, fingers teasing at his pulse without actually applying pressure. He doesn't realize he's leaning into it until Sakusa chuckles against his shoulders.

"Want me to choke you, baby?" Sakusa hums, growl returning his voice at the thought.

Atsumu blushes down to his chest once more even as he moans. "Please. Yes, fuck, please, please, ple-"

His begging is cut off by another choked moan as Sakusa applies pressure with his finger, cutting off the blood flow at the same time he adjusts the angle of his thrusts and finds the omega's prostate. Before Sakusa can even start loosening his grip, Atsumu's cumming hard across the bed with a loud cry that rips a snarl from Sakusa as his walls spasm around his already inflating knot.

"OMIII~!" Atsumu near sobs, going limp in Sakusa's hold as the alpha adjusts to grab his hair and pull him back into a hungry kiss, awkward angle be damned.

"Fuck, 'Tsumu," Sakusa growls when he breaks for air, pulling Atsumu's head to the side to start attacking his neck with bites and bruises as he continues pounding into the setter's sensitive hole. "So fucking hot." He sucks a dark hickey above the omega's mating gland, groaning when this makes him clench around the beginnings of his rapidly inflating knot. "So fucking perfect."

Atsumu keens at the praise and attention, moaning as his—yes his , he will officially fight a bitch that tries—as his alpha continues to use his limp body as a fleshlight. "O-mi…"

"Such a perfect omega. Fuck, you're gonna look so pretty stuck on my knot. Gonna fuck you so full of cum you have to wear a plug to the game. Gonna have you begging for my pups. Have you so thoroughly fucked, you'll be addicted to my cock. Make sure it's all you can think about is presenting and being my good little cum dump-Shit!" Sakusa outwardly moans now at how tight Atsumu clenches around him at the thought. "Fuck, 'Tsumu! You like that idea, baby? Want to be my good little omega bitch?"

Atsumu whines, high-pitched and needy as he nods desperately even if it's more of a flopping of his head. "Yes…please…wanna be…wanna be good…good omega…" He mumbles, anything after being lost to his whimpers and moans as his words make Sakusa pick up speed with a snarl.

"Fuck. How are you so perfect like this? Fuck, I hope you don't remember that. I'll never hear the fucking end of it but shit, 'Tsumu….Close." Sakusa growls, knot starting to catch as he continues to mouth at Atsumu's scent gland. "Such a good omega. Perfect mate….Mine…"

The final word is said in a growl that Atsumu can feel on his back as he moans. "Yes, Omi-Omi, yes…yers. …Yer omega… Yer mate…Please alpha…yer knot…want yer knot…yer bite…Omi-Omi, please…" He whines, still generally out of it even as he's fucked back to hardness.

Sakusa growls, hand around Atsumu's chest reaching down to start stroking the omega's cock as the other keeps a tight hold of his hair. He's so close he's beyond anything but the occasional grunt and near-constant rumbling, nearly howling when his knot finally catches, forcing him to grind into the setter's tight heat a few more times before he finally cums, biting deep into Atsumu's mating gland as he fills him with rope after rope of cum. A satisfied rumble follows.

Atsumu, meanwhile, between Sakusa's hand, knot, and bite, cums a second time with a fucked out moan that quickly turns into a pathetic whine as he's stroked into oversensitivity. "Omi~"

Sakusa grunts, finally pulling his hand away to just hold Atsumu as he licks at the new mating bite on the setter's neck. "Srry…" He sounds a bit slurred, probably drunk on hormones and the omega's scent.

"All good." Atsumu mumbles, purring as Sakusa carefully maneuvers them onto their side to wait for the next wave. "I get ta bite ya next round."

"I would…hope so…" Sakusa huffs, pumping out his already changing scent to smother his new mate in it. "Would be…pissed if you didn't…" He soon makes a whining noise specific to alphas but rarely heard. "Unless you change your mind when no longer cock du-Ow! What the fuck?!" A sharp elbow to his side has him back to clarity.

"Alpha or not, if ya thought ya were getting yer knot in my ass when I didn't want it, yer a fucking idiot." Atsumu scoffs, biting at the hand that moves to flick him in retaliation.

"Brat." Sakusa huffs despite nuzzling closer.

" Yer brat." Atsumu corrects proudly.

"Unfortunately." Sakusa sighs with the most unconvincing exasperation he's ever produced.

"I can leave, and let ya finish this alo-" Further sass is cut off by a yelp as Sakusa bites him like a petulant pup not wanting their toy taken away. "Now who's the brat?!"

"Still you," Sakusa smirks, kissing the spot he just bit.

Atsumu opens his mouth to retort, but is cut off by his hair being grabbed for a proper kiss…and another…and another. Sakusa doesn't give him a chance to respond and eventually kisses his pout away too.

"Hmm, guess I was right." Sakusa eventually hums when he has Atsumu smiling cutely.

"Hmm?"

A smirk. "There are better uses for that mouth."

"OMI!"

Sakusa's probably lucky the omega's trapped on his knot, but he always did like them feisty, and Atsumu more than fits the bill.

He really is a perfect omega.

Kiyoomi's perfect omega.

Notes:

For SakuAtsu Omegaverse Week 2023!

Trope: Bitching/Studding Quote: Kneel.

Same universe as Breakfast Food and Whiskey. Can be read separately.

"Come on, baby, kneel for me won't you?" Sakusa smirks as he crowds a laughing Atsumu against the wall of their now-shared MSBY dorm.

"Fuck off, Omi-Omi." Atsumu snorts, pushing the other alpha's shoulders with no real force. "It's yer turn, ya ass."

"But you look so pretty on your knees." Sakusa hums, letting a growl into his voice as he jokingly uses a Command, knowing full well it won't work on the other alpha. " Kneel ."

It shouldn't work on the other alpha.

Atsumu's eyes fog over as he drops to his knees with a whine before staring at Sakusa in mirrored shock.

Why the fuck did his Command work on the other alpha?!

"'Tsumu?" Sakusa whispers with a note of panic.

"Omi-Omi, I-" Atsumu cuts himself off, not even knowing what he was going to say.

He should have listened when Suna said he smelled different last time their teams played each other. Betas may not be as scent dependent, but as the peacekeepers, they were definitely more sensitive.

He thought they had been switching enough for it to not matter.

Omi had a really nice knot though.

Dammit, Atsumu had gotten himself bitched, hadn't he?

The two stare at each other for what feels like minutes as Sakusa reaches down to carefully peel off Atsumu's scent patch and is met with the normal star anise, lavender, and breakfast cinnamon trying to sour into whiskey with the setter's fear, but the lavender and cinnamon are faint compared to the pomegranate and blueberry muffin that has started to emerge.

Sakusa is just relieved he doesn't hate it like he usually does non-familial omegas. He just got the other alpha, soon-to-be omega back, he really didn't want to lose him again just because they literally fucked up.

Atsumu, meanwhile, whines, eyes widening in panic when Sakusa grimaces at the sound. "Omi-Omi, what's goin' on?" He knew the answer, but he was hoping he was wrong, terrified he'd lose the alpha again.

"I- I think we might have accidentally bitched you." Sakusa sighs slowly, nose wrinkling when the omegan panic smells like soured berries and the other notes sour as well. He quickly schools the expression when he smells more panic, however.

"But-but we switched!" Atsumu insists with a distressed whine. "How could this have happened?"

"Switching doesn't always work." Sakusa sighs, crouching to join the new omega on the floor and noticing his face flush when he finally realizes he'd never tried to get up. "Sometimes with alphas, if one is more naturally submissive or their alpha tends to bow to the other more often than not, a bitching will still happen." He had done some research early in their relationship in hopes of avoiding this exact thing. "…You were literally begging for my knot our entire rut."

Atsumu's face flames red at the faint memory. "I got myself bitched…" He whispers before looking into Sakusa's eyes pleadingly. "Omi-Omi, I'm so sorry! I swear I didn't mean ta-"

Sakusa winces as he realizes how accusatory he sounded as he grabs Atsumu's hands and rumbles to soothe him.

Unfortunately, the fact that it works only seems to make him panic more.

"Hey," Sakusa urges, waiting for Atsumu to look at him before he continues. "Why are you apologizing?"

"'Cause ya don't like omegas." Atsumu whimpers, further distress leaking into his scent each time he makes that sound.

Sakusa raises a teasing eyebrow. "Way to make me sound like an asshole." He smirks when it gets the intended laugh from the setter. "I don't like omega scents and sounds . So far only your distressed scent is bothering me. It still has the anise which was your strongest tone to begin with and pomegranate isn't overly sweet like most omega scents. The blueberry muffin seems to be your emotional scent and it's fucking sour right now, but otherwise not bad as far as the normal Willy Wonka nonsense that makes up omega scents." That one gets a surprised snort out of Atsumu.

"Willy Wonka-Omi!" Atsumu can't help but laugh, the distress leaving his scent slightly. "So, I'm the exception?" He smirks.

Sakusa, never one to allow Atsumu to get a bigger head than he already has, shrugs. "The only one I've met at least." Believing that to be neutral enough.

Atsumu pouts, but the sourness is gone. "Can't ya just tell me I'm special, Omi-kun?"

"Your head is big enough." Sakusa huffs, smirking when this gets an offended scoff from the other. "You okay, though?" He asks seriously now.

Atsumu deflates at the change in mood, but sighs, taking stock of his body. "I haven't noticed any other changes yet, but yeah, I'm technically fine, just a bit freaked out."

"Understandable. You're going through a complete biological overhaul." Sakusa nods, taking his own patches off to try to further soothe the now omega, rumbling back on instinct when Atsumu purrs. He makes a face at this feeling a bit like a bigoted slap in the face from the universe, but he has a distressed mate to take care of right now. "Do you want me to call Hinata for a crash course?" He offers as he subtly makes sure Atsumu's mating bite is still there and didn't get absorbed or something by the bitching.

Atsumu hums, leaning into Sakusa's scent that is definitely affecting him more than usual. "Hmm, I should…" He agrees, knowing that would be the smart option. He's had a long few minutes and is now worked up on the alpha’s scent. He wants some normal. "But I think we were in the middle of something." He purrs and oh, that part isn't too bad.

Sakusa's definitely more used to responding to another rumble or chuff so it takes him a second, but eventually, his own sounds join the mix, even as he tilts his head. "Are you sure? You just discovered you're accidentally changing secondary genders. Is this really the time."

"I'm still horny an' want a distraction." Atsumu shrugs honestly. "We have practice in the mornin' then the weekend off. I'll have my breakdown then."

Sakusa raises an eyebrow, positive that shouldn't be how that works, but having unfortunately witnessed Atsumu accomplish it more than once. He still sighs. "I don't know, 'Tsu-"

"Come on, Omi-Omi." Atsumu pouts, the mahogany in the alpha's scent being the only reason he's still pressing the issue as he leans in close to play with the hem of the spiker's shirt with a flirty smirk. "I kinda liked ya Commandin' me. Was a little hot after the initial shock an' panic."

'There it is.' Sakusa thinks with a sigh and a shake of his head. "Anyone ever tell you you're a menace?"

"It's been a few hours," Atsumu smirks, knowing he's won. "Is that a yes?"

Sakusa thinks about it for another moment just to be difficult before the growl returns to his voice. " Go to the bed, omega . Open yourself up for your alpha's knot. Don't stop until I join you ."

Something about the taunting quality added to the new title has Atsumu's eyes widening even as they fog over and he mindlessly wanders to the bedroom against his will. It's as terrifying as it is arousing as each flash of consciousness has him in a new state of undress and a new position. By the time he comes to and has control of his body back, he's already three fingers deep and keens as he realizes there's slick trickling between his fingers. Not a standard omega amount by far, but it's getting there and something about that has Atsumu moaning.

Sakusa, meanwhile, mostly gave him that task because he knew it's be just arousing enough to keep Atsumu occupied while he stared at his phone in panic, wondering if he should call his cousin or Hinata for help. He'd been with omega's sure, but it'd been a second and he had since done his best to forget about the unfortunate and embarrassing encounters.

A loud moan from the bedroom makes him settle on Komori since Osamu should probably know too.

Thankfully, he doesn't catch any of them in a similar situation again so he doesn't have to yell at his cousin for answering the phone while getting railed again .

{Kiyo!} Komori's grin is obvious even through the phone. {What's up?}

"I accidentally bitched Atsumu, what do I do?!" Sakusa rushes out, wincing when he hears his current lifeline start choking on whatever he was eating.

{You did what ?!} Komori coughs, yelling something away from the receiver that Sakusa can only interpret as calling for Osamu based on someone yelling about a scrub doing something.

"I can promise you we didn't mean to, but he wants to try this and I entirely blocked the disastrous omega encounters from my memory." Sakusa groans, ears hot as he listens to Atsumu down the hall. "What do I do about this and what do we do in general."

{Kiyo, Kiyo, Kiyo.} Komori sighs teasingly. {We were supposed to be past the age of the birds and the bees.}

"Do you want me to grace that with a response?" Sakusa warns, smirking when Osamu speaks over Komori to give a resolute {NO!} the other alpha not nearly as comfortable with hearing about people’s sex life as his menace of a cousin. "Good, now help!"

{Okay, okay.} Komori laughs. {What's he doing now?}

"He liked being commanded so I sent him to the room to get ready to give me time to panic." The spiker answers, a rumble starting in his throat when he listens down the hall and hears what has to be Atsumu working himself through an orgasm without being able to stop due to the Command. "Oh, so that's the appeal of Commands."

He can hear his cousin snort and probably shake his head. {You gave him some evil release condition, didn't you?}

"I forgot my cousin doesn't know how to get to the point, yes." Sakusa snips, sniffing the air to make sure the desperate noises don't hold actual distress.

{Fine, fine.} Komori sighs, grunting as he probably plops on the couch. {You're already doing fine with sex just know omega's are really sensitive and use that to your advantage. Anything else, I'll send over a few articles. …He's going to be extra clingy when knotted so take that into account when positioning. Otherwise, go take care of him before he fucks himself unconscious.}

Sakusa's face flushes at the bluntness of his cousin's statement before spitting out a quick goodbye and hanging up before he can be ribbed anymore. Hinata probably would have been the better option, but he cares too much and probably would have barged in with a care package or something.

"OMIIIII~!"

Speaking of caring.

Sakusa hurries down the short hall, stripping his clothes as he goes so he's ready by the time he stands in the doorway to ogle Atsumu whimpering on four of his own fingers.

"Omi-Omi~!" Atsumu's tear-filled eyes meet charcoal as he whines. "Please. Fuck me, Omi. Please. I'm already soaked, an' if I don't get a cock in me soon I might cry." He begs despite looking like he's already on his way. “How do omegas do this shit?”

Sakusa growls low in his throat, taking big strides across the small room to shoo Atsumu's hand away from his hole and get his face in there to get a curious lick of the new slick. Yeah, still not his favorite, but he could work with it as he watches the already stretched hole practically beg for his cock itself and dribble slick as though to entice him.

It was certainly a sight, and he doesn't hesitate to gather some of the liquid to lube his own cock before remembering something with a curse. "Dammit! Do we have condoms?" He growls with what's left of his brain power, knowing neither of them is ready for pups.

Atsumu whines at the thought, giving a growl that doesn't sound nearly as intimidating as it did just last week and reminds him of his situation. "Nightstand maybe?"

Sakusa gets up, having to check both of them and cursing at the mess in Atsumu's only to find a single lone condom in that one. "Clean that later, right now…" The spiker smirks as he lets the growl return. " Present ."

Atsumu's eyes fog over again as he rearranges himself to be face down, ass up with his hole on full display, begging to be filled. "Hurry!"

"Patience." Sakusa hums, shoving his fingers in the new omega's dripping hole to slick up his now condom-covered cock before slowly pushing in. "I've-shit- I've got you."

Atsumu keens as he's filled, chest arching further into the mattress with the much easier stretch. "Omi-fuck- please ! I'm ready! I'm so fuckin' ready, just fuck me already!"

Sakusa snarls, his alpha having a field day with the knowledge that he had bitched the cocky setter into a whining, begging mess of an omega as he grabs muscular hips to pull him down to the base and hears him cry out in pleasure.

"Omi-Omi!" Atsumu gasps, already squirming with need. "Move! Please! I'm already soaked fer ya, fuckin' mo-"

The setter's whining is cut off by a firm smack to his ass and a moan.

"Nothing's changed, 'Tsumu. Don't think just because your scent's fruitier, you're getting any kind of special treatment." Sakusa smirks as he pulls out and slams back in to make Atsumu cry out. "You'll take what I give you and you'll fucking love it." He leans over the setter, gripping his hair to snarl in his ear. "Understand, omega ?"

Atsumu moans loudly, barring his neck on instinct with the scrape of fangs. "Yes, fuck, yes, please, alpha, whate'er ya want, anythin', please just fuck me please, alpha please!"

A snarl rips itself from deep within Sakusa's chest as he plants his hands on either side of the blonde's hair to start a fast hard pace that makes Atsumu near scream as he grips the sheets.

"Fuck, 'Tsumu." Sakusa growls, hips snapping as the sound of skin slapping skin fills the room with Atsumu's moans. "So easy to fuck you like this. A little time on your fingers and you’re wet and gapping enough to suck me in like it's nothing." A dark chuckle. "I had been joking when I said it last time, but I really just made you nothing more than a breeding bitch, huh? Just a hole for me to fuck and fill with pups and cum? I could just tie you to the bed with a dildo in and you'd be more than happy to be my knot warmer, wouldn’t you?"

Atsumu suddenly understands why the omegas in porn always respond so well to dirty talk. It had been hot before, sure, no doubt about it, but right now, the voice that used to belong to his alpha is howling in need, and fuck he really could die happy like that, huh?

"Fuck! Yes, Omi, yes! Fuck, please, yes, that sounds so hot, please, fill me with ya cum, fuck me heavy with yer pups. Anythin'. Everythin'. Whate'ver ya want just please just let me cum. Please !" Atsumu begs, absolutely desperate for it as his cock throbs between his legs, but some new instinct tells him he's not cumming until his alpha does now that he’s in him. "Yer knot, Omi-Omi, please, need yer knot?"

"Yeah?" Sakusa pants, groaning as he feels it already starting to rut against Atsumu's cheeks in preparation to lock them together. "Close, baby? Do you need my knot to cum?" He hums, smirking when he gets a desperate moan and a nod in response. "Already such a good little knot sleeve, aren't you?"

Atsumu nearly sobs as his balls tighten as though trying to cum, but he fucking can't and he's pretty sure he'd let Sakusa do just about anything to him at this point. "Yes! Please! Wanna be good fer ya. Need ta be good fer ya. Please, Omi-Omi, need yer knot so bad."

Sakusa groans, low and primal as Atsumu's pleas work him to the edge almost scarily fast, and he feels his knot start to catch. "Fuck! Yeah, take it, baby. Take my knot. So good. Such a good omega. Gonna stuff you so full you forget you were ever anything el-Shit!"

Sakusa nearly howls as his knot finally catches, locking him deep inside the omega who nearly screams as he cums, collapsing his full weight into the bed beneath him as he clenches and spasms around the cock inside him, successfully dragging Sakusa kicking and screaming over the edge with him as the alpha's cock is milked and his fangs sink into the new omega's mating gland once more.

It takes all of Sakusa's remaining brainpower to roll them onto their sides away from the cum so he can hold the purring omega close as they wait for his knot to go down.

"Fuck, 'Tsumu." Sakusa eventually breathes in disbelief. "The fuck was that?"

Atsumu just mumbles something unintelligible, having no clue himself as he waves at the phone he had managed to get onto the nightstand before continuing to obey the earlier Command. "'Samu's…sound…"

Sakusa frowns, not really wanting to deal with the omega's twin during afterglow time, but knowing that was fucking weird even for them.

Taking advantage of his long limbs and freaky wrists has him tossing the phone back on the nightstand with a snarl.

"What's wr-ong, Omi-O-mi?" Atsumu slurs into Sakusa's arm, brain high on mating endorphins.

"It's called bitching for a reason." Sakusa huffs, glad Atsumu is facing away from him so can't see his blush. "Just need to undo it or get your hormones stabilized." The alpha covers the setter's mouth before he can be cut off. "Decisions you can make when you're in your right mind."

Sakusa can feel the pout against his hand, but Atsumu thankfully doesn't fight him on it, simply shrugging as he snuggles as close as their position will allow. "Sounds…good, Omi-Omi." He purrs.

"Mhmm." Sakusa hums, nuzzling into dyed blonde hair. "Now sleep."

Atsumu has no complaints there. They have plenty of time to figure this mess out.

Right now? Right now, he just wants to bask in the warmth of his alpha's arms.

His alpha, no matter what.
