Work Text:

Ushijima and Oikawa had been courting each other for a few months before their match today. The alpha had finally gotten the highly sought after omega to go on a date with him after he showed up at the Seijoh gym late one night with flowers, milk bread, and a sizeable plushie of a star. He vividly remembers the way his heart was beating from his jog to the gym and his nervousness. Oikawa had just finished his solo training regimen and was quietly panting, his face red and eyes looking up at him suspiciously.

‘Please allow me to take you on one date, Oikawa,’ he remembers asking. Oikawa’s minty scent was muddled by his exertion, but Ushijima would still have recognized that scent from anywhere.

Oikawa takes a deep breath and lets it out slowly, his cheeks puffing up ever so slightly at the action. He huffs and nods his head, still squinting at him as he holds his hands out to take the gifts. Ushijima’s eyes widen and his lips quirk up as he hands over the gifts, bowing to show his gratefulness.

“Tomorrow,” Oikawa mumbles as he stares at the star plush, “lunch. Somewhere nice and relaxed. I expect you to take me there.” Ushijima nods seriously and he can feel his heartbeat when he catches Oikawa hugging the plush with one arm.

“I will promptly be at your home at noon,” Ushijima says, doing his best to hide the exhilaration coursing through his body.

-

The date, evidently, had gone very well, Ushijima reminisces as he watches Seijoh warm up. Ushijima took a sip of his water and brushed his hand across the scent blocker patch on the crook of his neck that all persons in the gym had to wear so as to not distract the players.

Conveniently, it hid his and Oikawa’s scents so that no one knew that they were dating.

Ushijima had known that Oikawa would want to keep their relationship a secret due to their one-sided rivalry stemming from middle school. He had never paid it any mind…except when he caught other alphas lusting over his boyfriend. Only in those times did he wish that he could scent Oikawa heavily or be able to outwardly protect him by showing their relationship. Now that he thought about it, that was rather often.

It’s no secret that Oikawa is one of the highest sought after omegas in their high schools. He’s attractive, a leader among all, and demands followers everywhere he goes. Ushijima faintly smiles as he watches Oikawa toss his last set. He feels so lucky to have Oikawa to himself.

The whistle blows and both teams line up to greet each other. He shakes Oikawa’s hand and squeezes gently, happy when he receives a squeeze back even though Oikawa’s face makes it look like he hates him. The coin is tossed and the game starts.

Teams are cheering everywhere and whistles are being blown left and right. Their match is on the A court while another match is happening on the B court. Shiratorizawa takes the first set much to Seijoh’s annoyance and the teams take their break before the second set begins. Ushijima glances over to Seijoh to see Oikawa rubbing his temples with his eyes closed. A flare of jealousy lights up in him when he sees Iwaizumi running his hand up and down Oikawa’s back, but he knows that they are just close friends. He trusts Oikawa and nods to himself because he knows that Oikawa chose him. If anything, Ushijima is concerned about his boyfriend’s feelings at the moment and wishes that he could be the one to comfort the omega.

The second set starts and turn by turn, Ushijima and Oikawa are both in the front lines facing each other. Oikawa glares at him with his slightly pouty lips. No taunting this time around, it seems. Before the ball can be set, there’s a commotion from the other court and the referee calls for a time out.

Ushijima watches the other court as red and green mix together while they huddle over their teammate. He isn’t quite sure what happened, but as a sweet scent mixed with a more bitter one wafts over the gym, he can guess. He watches as a red-jerseyed player stands up with a green player wrapped around his front and rushes off the courts.

The referees in charge of the Shiratorizawa and Seijoh match blows their whistles and the two teams get back into position. Seijoh takes the second set with Oikawa’s service ace and Ushijima never fails to find the sight and power of the omega’s serve arousing. He watches Oikawa as he gets off the court and sits back on the bench, hunching over as he takes deep breaths. He doesn’t have much time to observe the omega before their coach is talking to them.

The third set begins and the teams are point for point in the middle of their set. Ushijima watches intently as Oikawa serves again. The ball is received by Reon and Shirabu is about to toss to him. Ushijima runs forward for the spike and sees that Oikawa has also made it to the front to prepare for the next move.

Shirabu tosses the ball to him, but Ushijima doesn’t jump.

He feels like he’s moving in slow motion. His teammates and coach are in shock and yelling his name as he dives forward, under the net instead. He had unconsciously been watching Oikawa out of his periphery and a wave of dread crashed on him.

Oikawa’s quiet gasp was ringing in his ears as he watched the omega clutch his stomach, his knees buckling as he fell backwards. Ushijima willed his body forward to hopefully catch Oikawa, if not at least soften his fall.

He felt a body colliding into him, his elbows rubbing against the gym floor as a warm weight wiggled in his arms. Ushijima was quick to sit up and re-adjust the setter in his arms as whistles blew all around him. None of that was loud to him when he could feel Oikawa gasping for breath against him. Now that the setter was sitting on his lap and looking up at him, Ushijima could see the glassy look in his eyes and the deep blush running across his cheeks.

“Oikawa,” Ushijima whispered, using one hand to swipe Oikawa’s bang away from his face, his other one gently cupping the setter’s neck.

“Ushiwaka…alpha,” Oikawa gasped back, arms circling around his neck and picking at the scent blocker. Oikawa whimpered as he struggled with the sticker, “scent…!”

Ushijima hadn’t noticed the two teams crowding around them, watching them in shock. He was focused solely on his omega and the increasing sweet smell that was coming off of him. He reached a hand up to rip away his and Oikawa’s scent blockers. The omega immediately dug his head into the groove of Ushijima’s neck, holding onto him tightly as his body shook with pain and adrenaline. He whimpered as he felt two strong arms encase him comfortingly, slick starting to come out from him.

“It hurts…” Oikawa sniffled, his cramps hitting him hard.

Iwaizumi slowly crouched down, noticing Ushijima stiffen as he started to take in his surroundings, his body tensing as he was prepared to protect the omega. There was no denying it now. The mixed scent of earth and mint from the two of them told everyone that they had scent marked each other previously. Iwaizumi held up his hands as a sign of peace and was now sitting on the floor and leaning towards the omega.

“Tooru,” he said quietly, trying to coax his best friend to look at him. Iwaizumi could feel upset about the secret relationship later, but right now he needed to focus on the omega in front of him. He slowly reached a hand out to pat Oikawa’s head, letting his familiar scent help comfort him. He could feel Ushijima’s protective instincts riling up against the touch, but it quickly simmered when Oikawa picked his head up to look at him.

“Hajime?” He sniffled, leaning into his hand.

“Do you want to go home?” Iwaizumi asked softly.

“Mm…” Oikawa whimpered, nodding into Ushijima’s shoulder.

Iwaizumi nodded and stood up, Hanamaki and Matsukawa clearing a path for them as he told Ushijima that he was going to drive them home. He watched to make sure that Ushijima could stand up while holding Oikawa and when they were both up, he started leading them to the car.

One of the medical staff stopped them to do a quick check on the omega, telling them about another omega went into heat during a match not too long ago too and that that might’ve pushed Oikawa into an early heat. Their coach walked up beside them and reassured them that the match would be moved as well. Hanamaki and Matsukawa had also run over with Oikawa’s and his bag while Shirabu had gotten Ushijima’s. 

He hauled all three bags over his shoulder and shoved them into the trunk when they got to the car. Iwaizumi opened the back seat door for Ushijima to get into, being careful so Oikawa didn’t hit his head. He got into the front seat and rolled the windows down so he wouldn’t suffocate from Oikawa’s pheromones and started the car to get them home as soon as possible.

Oikawa was sweating and panting as his cramps increased in frequency. He was quietly crying in Ushijima’s hold and squeezing his shoulders with his nails. Ushijima couldn’t do anything except rub his back and make quiet shh sounds in his ear. His instincts were flaring up with the urge to take the omega then and there because of how good he smelled and the slick that was starting to stain his pants.

“Ushijima, calm down,” Iwaizumi said as he glanced at the rear view mirror, “the more riled up you get, the more riled up Oikawa’s going to get.”

Ushijima nodded and took a deep breath, squeezing the omega in his arms as he does so.

“I’m taking you to his house. His room is on the top right.” Iwaizumi groans as he says the next sentence, “please use protection.”

After receiving another nod from the distraught alpha, he sighs and concentrates back on the road. They get there in top time and Iwaizumi was quick to open the back door and the trunk, pulling Oikawa’s and Ushijima’s bags out and fishing around for Oikawa’s key. Once the door was open, Iwaizumi left both bags on the floor and turned to leave, but not before reminding Ushijima to use protection again and warning him to be careful with his best friend.

Oikawa groaned in his arms and Ushijima rushed upstairs and into his room, peeling him off of himself so he could lay the omega onto his bed. A spike of warmth ran through him when he saw the star plushie sitting in the corner of Oikawa’s bed and the memory cleared his senses for a bit. He started undressing the setter, being careful even though he was resisting being moved around.

Once he was undressed, Oikawa whimpered and pulled on Ushijima’s arm, tugging him down onto the mattress and shoving his face into his neck.

“Alpha,” he moaned quietly, arching his back up so their chests brushed against each other, “please.”

Ushijima swallowed as he felt blood rushing down into his cock, taking a deep breath before pulling Oikawa off of him.

“Condoms?” He asked.

Oikawa pointed to a drawer next to his desk. Ushijima quickly went over and grabbed one, putting it on the nightstand as he started undressing. By the time he was completely naked, Oikawa was already sticking a finger inside himself as he writhed on the bed. Ushijima growled as his instincts started taking over.

He got on the bed and hovered over Oikawa, snatching the omega’s hands and pinning them above his head. Oikawa moaned and looked up at him with glassy eyes and red cheeks as he strained his neck up for a kiss. The omega gasped as Ushijima gave him a rough kiss; teeth clashing and tongue domineering. He closed his eyes as a wave of heat rolled through him and pushed more slick out from his body.

“Mmm...Alpha!” He moaned when Ushijima broke off the kiss, digging his feet into the bed as he raised his hips in want.

Ushijima let go of his hands and leaned back on his heels as he grabbed Oikawa’s hips tightly and flipped him over, raising his ass in the air. Oikawa’s whine was cut off with an obscene moan as Ushijima started lapping at his hole with his tongue. He licked around it before sticking his tongue inside, leaving bruises on the omega’s hips as he squirmed and shuddered.

Oikawa gripped the sheets hard, the fabric bunching into his hands and he thrusted back onto Ushijima’s tongue, needing something to go deeper in him so the lust in him could subside. He could feel heat coiling in his lower stomach, but it wasn’t enough. He gasped for more and cried out when Ushijima removed his tongue, only for it to be replaced with two fingers. Each time they thrusted in, he was moved forward and back.

“More!” He gasped out. Ushijima grunted behind him and pushed him flat down onto the bed with a hand on his back. A third finger was added and Oikawa squealed at the powerful thrusts attacking his prostate. He could feel his eyes rolling up as Ushijima started moving faster and he became louder when the pressure and heat started getting too much. He hadn’t even noticed when he started drooling onto his bed.

“I’m going to-!” He choked out as the hand on his back moved off.

Ushijima looked down at the writhing omega below him, hand never stopping as he thrusted harder and harder into the boy. His cock was throbbing as he moved his free hand to squeeze Oikawa’s ass, feeling the muscles clench around his fingers tighter as he was approaching orgasm. He lifted the hand and Oikawa’s ass and smacked it hard, pushing his fingers in as deep as they could.

Oikawa let out a choked moan as he shuddered and came, Ushijima fingering him through it until he was quaking in the aftermath.

Ushijima turned him back onto his stomach, taking in the sight of the beautiful omega. He felt his cock throb and he wrapped his hand around it and pumped slowly while watching Oikawa slowly become aware again.

After a couple minutes, Oikawa’s breath evened out again and he pushed himself up onto his elbows, watching the alpha intensely. Without a sound, he sat up then got onto all fours, crawling over to the alpha. He pushed Ushijima’s hand away from his cock and started mouthing the tip with his lips, his tongue peeking out occasionally.

He used one of his hands to grab the bottom half of the alpha’s cock and started taking him in deeper with his mouth. He felt lust go through him when Ushijima groaned above him and pushed himself to take more of the cock in his mouth. Ushijima watched him intensely and ran a hand through his hair, gently scratching his scalp in endearment. Oikawa let out a happy sound at the action and felt the alpha’s cock throb.

Ushijima enjoyed himself for a bit more before tugging on Oikawa’s hair. The omega let go of his cock with one last pop of his lips and looked up at him with big, innocent eyes. Every instinct in Ushijima was telling him to take his omega right now and after quickly tearing open the condom packet and putting it onto himself, he pushed Oikawa back onto the mattress and spread his legs.

Oikawa mewled when the three fingers pushed back into his hole, feet pushing against the mattress in pleasure as he head rocked back. Ushijima leaned over him and sucked on one of his nipples, tongue licking around it as Oikawa shivered. The omega wrapped both his arms around Ushijima’s head, scratching at it in the wake of his pleasure. More slick was starting to come out of him again as the alpha made him feel good, his heat demanding him to mate right then and there.

Ushijima pulled away and sat back up again. He pulled his fingers out from Oikawa’s hole, using his thumbs to stretch out the skin around there so he could see it clearly. He grabbed Oikawa’s hip with one hand and guided his cock to the hole with the other, watching Oikawa’s expression as he slowly pushed in.

Oikawa gave a low moan as the cock sunk in inch by inch. His breath catching when he felt Ushijima bottom out. Ushijima grabbed both of Oikawa’s thighs and started thrusting slowly, feeling the heat wrap around him. He looked up at Oikawa and started going faster while watching the pleasure on his face escalate. He moved the omega’s legs off the bed and onto his shoulders, turning his head to kiss the setter’s knees before bringing his hands down to grip at his hips again.

Oikawa started crying. He felt so good, but also so happy and loved by Ushijima. He held his hands up and was delighted when the alpha leaned down. He cupped his cheeks and strained up to give him a peck before collapsing onto the bed again. He wasn’t flexible enough to have Ushijima lean all the way down on him.

“Feels so good,” he breathes out, smiling when he feels Ushijima start moving faster in him, “such a good alpha.”

Ushijima growls and starts pounding harshly into the omega, the compliments fueling his desire. He can feel slick spilling out of Oikawa’s hole around his cock and the omega’s words soon turn into gasps as he clenches around him. He watches as Oikawa throws his head back, leaving his neck exposed vulnerably to him. His eyes are closed and his body has turned a shade of red from the physical exertion. His hands rest to the side of his head and grip at the sheets beneath him.

This omega is his. Ushijima grips at Oikawa’s hips until the omega yips in pain, pushes his cock into the omega hard enough that he bounces each time. Every instinct in him is telling him to claim Oikawa and he does. He leans down over the omega, his hips going up as his cock changes angles so he can push in deeper.

Oikawa absolutely screams in pleasure at the new angle and Ushijima only does his best to please his omega. Oikawa is impossibly tight around him, mouth open and eyes closed as he moans loudly. The omega’s breath starts picking up and Ushijima can feel him start to quiver.

“Ushi-ahh!” Ushijima leans completely down and bites the crook of Oikawa’s neck as the omega’s moan chokes and his eyes roll back as he orgasms. Ushijima cums deep into the omega as a rush of pleasure goes through him as he bites into Oikawa’s neck.

He feels Oikawa shuddering around him as he slowly comes back to awareness. He unlatches himself from the omega’s neck and feels a heat in his body when he looks at the mark he left. Oikawa moans softly as Ushijima lets his legs back down and pulls out. The omega’s head is turned to the side and his hands rest to his side, eyes closed.

Ushijima gets off the bed and pulls the condom off, tying it up neatly and throwing it in the trash. He sits back on the bed and drinks some water that was on the nightstand before gently lifting Oikawa up into his lap, letting him settle against him. He brings the water up to Oikawa’s lips and waits until he’s done drinking before capping it and putting it aside.

Oikawa is unresponsive besides the occasional grunt as Ushijima prepares as bath for them, but he seems to be alright. Once the water is high enough, he turns off the faucet and picks up Oikawa only to slide him into the tub. He gets behind him and cradles him in his lap. Oikawa smiles and turns his head to peck his cheek, finally opening his eyes.

“Ushiwaka-chan~” he leans back into him.

“Hm?” Ushijima grunts, massaging Oikawa’s waist underneath the water.

“I’m a pretty big handful during my heats,” he giggles.

“I will take care of you,” Ushijima rumbles, turning his head to kiss Oikawa’s nose.

“You’ll take care of me,” Oikawa repeats, smiling softly at him and closing his eyes again as he relaxes.

Ushijima lets out a sigh and closes his eyes as well, just enjoying the two of them together.
