Atsumu had not been able to get a good pure whiff of Hinata earlier when Kageyama’s deceptively overpowering scent had been permeating the air, especially over Hinata. What a possessive fuck, subtlety scent-marking his favorite spiker. Also, no one who had what was supposed to be the placid scent of a particularly refreshing stream (cool, clean water with wet moss and smooth stones lining the bottom) should smell that strong.
So, when he and Hinata happened to meet in the bathroom, locking eyes as Hinata entered and Atsumu was drying his hands, Atsumu for the first time was hit with Hinata’s scent.
He hadn’t even realized the boy was an omega. Although his Alpha wasn’t surprised in the least. Logically, he had deduced the boy to be an Alpha like their libero who smelled like a live wire. How could Hinata not be with the brilliant presence of a sun?
Apparently by way of logic-defying, which seemed to be Hinata’s entire existence with his speed and jumps.
And man, Atsumu was not prepared for Hinata’s scent. Fresh tangerine’s bursting behind his skull and mint soaking on his tongue like he had been chewing on a fresh leaf plucked right from the herb.
The scent clicked with his perfectly. Cinnamon and cedar mixing with citrus and mint, exploding as if Atsumu had been transported to a particularly bountiful forest.
Their biology was perfect for each other, his alpha told him.
For that brief moment – when they’re locked in stillness, stuck in the potential before the kinetic, before everything goes to complete and absolute shit – they locked eyes. And Atsumu knew that Hinata had come to the same revelation as Atsumu had.
They were Perfect Mates
Atsumu lunged, alpha canines dropping to their full force and sinking into the juncture of Hinata’s neck as his hands grabbed his upper arms and held him tight so that he couldn’t escape. Couldn’t try and shake off the unfamiliar Alpha claiming him as his.
Hinata jerked and froze as the fangs sank into flesh and glands but his hindbrain must’ve kicked into gear because he shrieked and kicked his feet out. This only resulted in his feet losing traction giving Atsumu even more power and leverage as he curled over the toppled omega.
Hinata fought and fought, the dirty primal fight of an omega not properly prepped enough to submit to a claim mark. Hinata didn’t have months, at the least, of courting and wasn’t deep in the bliss of heat where a satiated omega would receive a claim with pleasure and pride.
No, Hinata had a dirty bathroom with an alpha he hadn’t had a full conversation with.
Atsumu despite this didn’t pull his fangs out and instead growled, warning Hinata to stay still. Warning others to stay away from him and his Omega.
Because when he had pointed, he had verbally staked his claim (Kageyama had known on some level if his peeved off expression had meant anything) and after smelling how perfect Hinata was for him, that he was an omega of all things and all Atsumu had to do to (as far as his stupid alpha knew) keep him was to bite well… Atsumu wasn’t going to let him just walk away.
Hinata was screaming his head off and then it choked off and then he was convulsing. Atsumu could see his expression from the bathroom mirror. Had been watching the shock, the pain, the fight and now he watched as his mate’s eyes rolled into the back of his head and he jerked as the claim mark settled.
Only when he stilled, did Atsumu gingerly remove his teeth from the home they’d made in Hinata’s flesh, right in the glands.
Hinata moaned gravely, head lolling and Atsumu guided him down to the floor where he curled over his mate even more, keeping him out of sight from the purveyors around him. Because they weren’t alone in the bathroom, yet no one had stopped him.
He was sure that some goody alpha would have stepped in if anyone had seen this coming. Hell, if he had watched this happening, if some Alpha creep had sauntered up and made moves to claim an Omega, he would have stepped in
Except even Atsumu hadn’t even seen this coming. His Alpha making split-second decisions based off of biology and instinct. He wondered if Hinata had seen this coming.
He licked over the wound, wiping the blood and a mix of their pheromone oil from it – Hinata’s leaking straight from his scent gland and Atsumu’s from the oil scent in his saliva – cleaning and reapplying his scent to the open wound of Hinata’s scent glands. His Alpha purred at the mixture of their scents. Hinata shivered with each swipe of his tongue.
People started moving. One beta tried his luck trying to get close before Atsumu growled at him, baring bloody teeth. He wondered if his eyes looked feral. If he looked feral. He must’ve – sweaty hair mussed from playing, sweat still covering his body in a sheen and now his mouth was dripping blood and saliva.
The beta was quick to back up, into an Alpha who stood away and as a convenient wall to hide behind.
“ – shit! What do we do?”
He’s vaguely aware of people leaving. They pass too close and get warning growls and snarls as they pass.
Looking back down at his omega – his omega! – he watched as Hinata blinked up at him blearily, blissed out and exhausted. A hand came up and cupped his face, keeping his head tilted down, even as Atsumu’s eyes flickered between his mate and the rivals – threats – losers around them.
“Atsumu,” Hinata crooned, “Atsumu.”
The hand stroking his cheek was lulling Atsumu, bringing down from the adrenaline apex of claiming.
“That’s it, shhh… Alpha calm down.”
Atsumu felt the tension roll out of his body. He started scent marking aggressively, releasing his pheromones to cover Hinata (to wash away the remnants of Kageyama’s scent which while overpowering seemed to roll away like the water it imitated) and nuzzling his face and neck, being careful of the open wound he had caused.
“Wait don’t,” Hinata wiggled and Atsumu gave a low warning growl, not the same dangerous timber but a minor displeased sound.
Hinata snorted and kept turning away from the scent marking. Atsumu’s hands gripped harder.
WHACK
Atsumu reared his head back at the smack on his nose, letting out a confused whine. If it had been anyone other than his omega – even his own mother and especially his brother – he would have sunk his fangs into the hand. But if it was his Omega, freshly bitten, reprimanding him then it must be important.
“Atsumu!”
Atsumu blinked and looked down at his Omega who was staring at him, his eyes intense with mettle.
“Wh-what?” Atsumu managed to articulate.
“You need to stop,” Hinata said slowly, “Because you’re going to send me into heat.”
Atsumu felt his face stretch into what must have been a goofy, love-struck smile because he felt goofy and lovestruck. He gave a pleased purr and went to keep doing what he was doing but was stopped by another little bop.
“Atsumu! I can’t go into heat I have to play in Nationals. We’re in a bathroom in the National Gym. You just claimed me in a bathroom at Nationals!”
That kick-started Atsumu’s higher brain functions back into action and his eyes peeled fully open as he stared down at Hinata. 164cms of a (rightfully) indignant and debauched Omega.
He tried working his mouth but he didn’t have any actual words to try and string together.
He looked around and saw a disgusted alpha and a very concerned beta hiding behind the alpha – the beta who had tried to interfere.
“Oh my god,” he finally managed to get out.
“Hey, you finally with me?” Hinata asked, his voice raspy from screaming bloody murder. And maybe it was supposed to be snarky but he ended up sounding entirely too tender for someone who had just been assaulted.
“Oh my god,” Atsumu backpedaled, ready to curl up in a ball, or better yet beg his – no not his – Omega for forgiveness.
Except Hinata’s hand was stopping him.
“Hey, where are you going?” Hinata spit, “You can’t leave. I can’t even move yet.”
Then things got worse.
“Hey, there’s no way that Hinata’s involved in this, right?”
Hinata turned his head to listen to the new voice.
“I doubt even he could get in that much trouble, Sugawara-san. It’s been less than ten minutes…”
Make that voices.
“You know how he is Tsukki! His ‘bathroom encounters’,” a snicker accompanied this one, “We should check just in case.”
“You just want to see what happened, Yamaguchi.”
“Speaking of which, why didn’t anyone go with him?”
The voices were getting louder and then the door was opening and Hinata whipped his head to look at Atsumu and say, “Oh crap,” before they both turned, stunned at Hinata’s team and pack walking in.
It’s two of the benchwarmers and Karasuno’s tall, blond wall.
They pop the door open and freeze at the scene. Atsumu wonders how they look. He knows it looks bad for him (because he’s done something bad) and blood is dripping down their pack Omega. Inarizaki doesn’t even have an Omega, just a bunch of rowdy alphas and instigating betas and Kita the most level-headed beta keeping them all together.
And now he’s bitten and claimed another pack’s omega when he didn’t have the right.
I never even an initiated courtship! Atsumu mentally wailed at himself.
“Haha, hey guys!” Hinata laughed awkwardly from the floor, “So, uh…”
The tall blond stiffened, body ready to pounce as he took in the situation. The vice-captain looked down at him blankly and the last one had a look of pure horror on his face.
Luckily, they were all beta’s or Atsumu would be fighting to the death already. Okay, he wasn’t sure if Kageyama was the type but he knew instinctively that the libero wouldn’t hesitate to tear him apart and god was the baldy or their Ace alphas?
“Oh shit,” Atsumu declared.
“Don’t say that!” Hinata reprimanded.
“Oh my god Hinata!” Surprisingly, it was the Beta whose face is filled with horror that moved first.
He darted towards his friend, hands freezing in the air as Atsumu started growling – he can’t help it! He just claimed an Omega!
Oh god he just claimed an Omega.
“Oh my god,” he reiterated again, “I – shit.”
“Don’t say that Atsumu-san!” Hinata chided then turned to his friend, “Ah, sorry Yamaguchi could you get me something to wipe the blood up?”
“Here,” the vice-captain beta handed off a handkerchief.
“Thanks, Suga-san…” Hinata started wiping away the blood.
I should be taking care of him what kind of alpha am I to leave my omega cleaning up my mess?
“Hinata!” The blond finally snapped. Then as if realizing that his outburst could be classified as an outburst took a deep breath to try and reel it in only to lose it again, “Idiot. Idiot, idiot, idiot! What happened?! We leave you alone for ten minutes and then this happens?”
Hinata snarled, sending the blond beta back a step before he bared his teeth.
“Tsukishima,” the vice-captain intervened, “I know you’re worried but maybe you should go get Diachi. And probably Takeda-sensei and Ukai as well. And if you run into any Inarizaki players let them know Karasuno needs to talk to them.”
Oh god Kita was going to kill him.
Atsumu whined pathetically and Hinata huffed and reached up to pull Atsumu’s head to his chest where Hinata’s heartbeat was steady if a bit fast.
“Calm down,” Hinata demanded, “You’re not allowed to freak out you bit me.”
Oh god he had. All three of the betas – because of course blondie hadn’t left yet – sucked in a sharp breath of air.
“I’m sorry,” Atsumu whined.
“Don’t you dare say you’re sorry,” Hinata snapped, pulling Atsumu up so he could look the alpha in the eyes, “Pull yourself together! You’re an alpha, aren’t you?! Where’d all those guts go when you sunk your teeth in me?! Now if you ever want me to complete the bond you are going to get up and present yourself to my pack as a potential courting partner and beg them to accept you. And then you are going to inform your team that you’re courting an omega.”
Complete… The bond?
Atsumu gaped down at the spitfire omega. He wasn’t just going to wait the scent out and try to get someone else, maybe even Kageyama (and god if that didn’t make Atsumu want to break something) to bite over it?
“Y-you want… You want me even when I -?” Atsumu’s eyes flocked down to where the skin was red and puffy around the bite incision.
Hinata bared his teeth, “We’re perfect mates! And you said you’d toss to me! The only reason I didn’t bite you is because I have to play more and we are in a bathroom! You bit me in a bathroom! What if I went into heat? Would you have kn-knotted me in the bathroom? There are people here! Oh my god… People watched me get claimed. You’re the worst.”
“I’m sorry!” Atsumu whined, “Ya deserved a proper courtship! Not a bathroom!”
Hinata shook him, “Oh, I’m still getting a proper courtship! Now. Get. Up. And go beg my pack for forgiveness!”
Atsumu shot up to his feet. Hinata was still shaky so he helped him up and supported him. He peeked at the faces of the two beta’s that were left. The younger benchwarmer had a look of pure anger. Strangely the older looked… Exasperated?
A horrible thought occurred to Atsumu that the omega he had claimed might just get into extreme situations like this all the time. He must to react like this.
“Oh… Atsumu-san was it?” A voice called.
Atsumu made eye contact with the vice-captain, chin lowered, “Y-yes?”
“I was wondering. Do you know Bokuto-san?” Suga’s eyes sparkled with a vindictive amusement. Next to him, the other benchwarmer smirked.
“F-from Fukurodani?” What did he have to do with anything?
“Yeah that one. Him and his mate, Akaashi are pretty attached to Hinata.”
Atsumu’s face paled. He had seen Bokuto-san spike a volleyball.
“Good luck. Really!” He said with a wave as Hinata pulled him through the bathroom doors.
Atsumu paled.
