Work Text:
Oikawa shouldn't have taken that bet. The omega knew he shouldn't, but he never doesn't accept a challenge. Worse than that, he shouldn't have let Makki have the vibrator remote.
Iwaizumi would have smacked him in the head and scold him for being so stupid. But unfortunately Iwaizumi was in a different class, so Oikawa had anyone to save him from his own stupidity.
When Oikawa arrived at school that morning, Hanamaki had said out loud that no one – least of all an omega – could endure spend all morning with a vibrator stuck up into their ass.
Right, Oikawa? The pink haired beta had looked at his friend with the biggest shit-eating grin on his face.
Oikawa should have insisted on keeping the remote vibrator, but Makki argued that he had no way of knowing if Oikawa was cheating.
Oikawa felt so stupid as he squirmed in his chair, rubbing his thighs together, feeling the vibrations rise to their maximum and then stop completely. Sometimes the vibrations took just a few seconds to come back, sometimes they took long minutes. It was maddening.
Makki was looking at him over his shoulder, grinning like the fucking Cheshire cat.
Oikawa could feel a worrying amount of slick pooling up in his boxers. And honestly, he was starting to dread the moment when the alphas in his class would start to smell it. He didn't know if it was just an impression, but he thought he saw his classmate, an aplha who sat in front of him, discreetly sniffing the air.
Excusing himself, Oikawa asked to go to the bathroom and practically ran out of the classroom before the teacher even gave permission. He heard Hanamaki's devilish laugh before he closed the door and the vibrations inside his hole came back at top speed again.
He nearly fell as he ran to the bathroom, his legs weak and shaky. He could feel his cheeks burning hot and his breathing quickening. The omega was so desperate to get to the bathroom soon so he could shove his fingers into his soppy hole and get some relief, that he only realized someone was heading his way when he hit a massive wall of muscle and would have fallen if an arm hadn't supported him.
"What the fuck, Shittykawa? Why're you runing like that?" He heard Iwaizumi's husky voice and nearly cried.
"Iwa-chan" He whimpered, clutching at the alpha's shirt hard and buring his face in Iwaizumi's chest, inhaling sharply. Hajime had always smelled so nice.
The alpha held him tigher, feeling something wrong.
"What happened? Did someone hurt you?" Oikawa lifted his gaze to his best friend, seeing a worried crease between his brows.
Then he saw when Hajime's expression changed. The alpha sniffed the air, his nostrils flaring and his pupils dilating. A low growl from the alpha made the omega shudder and moan, and he felt more slick pouring out of his hole.
Tooru didn't even fight when Hajime dragged him away. He didn't ask where he was taking him when a protective arm wrapped around his shoulders.
"Iwa-chan..." he mewled pathetically, but Iwaizumi just shushed him.
The boy recognized the closed bathroom for maintenance on the second floor. It had been closed for years, and was used by students who wanted to fuck. Oikawa himself had fooled around with alphas a few times in that same bathroom, but he had never entered there with Hajime.
Oikawa whimpered at the thought of being fucked by Iwaizumi inside one of those dirty cabins. He'd fantasized about it more times than he could count, with the alpha lifting him with those huge arms and poundind into him hard against a wall, whispering dirty into his ear.
"What's gotten into you? Why are you smelling like that? Are you in heat?" Hajime shoted off the questions as soon as he let go of Tooru. The omega leaned against a wall, thoughts of being knoted by his best friend still running through his head.
The vibrations hadn't stopped – Makki seemed to be having more fun than ever – and Tooru had to stop himself from moaning and rubbing his thighs around his best friend.
He shook his head and licked his lips, trying to think more clearly, but Hajime's pheromones made that a difficult task. The alpha didn't even seem to realize he was releasing such strong pheromones. Between ragged breaths, Tooru explained about Makki and the bet, and god, he felt even more stupid saying all that out loud.
"Oh my god," Iwaizumi ran a hand through his face and hair, letting the spiky strands even messier. "I'll kill you and then kill that asshole."
Tooru pouted. "Don't be mean, Iwa-chan."
"Shut the fuck up Dumbkawa." The alpha groaned, pacing the bathroom back and forth. "Do you have a spare change of clothes?" Tooru shook his head again. "Of course you don't."
Iwaizumi sighed heavily. With the walk to the bathroom, the vibrator had lodged itself over his prostate, and with a particularly strong vibration, the omega ended up letting out a loud moan.
He saw that same expression on Iwaizumi's face again. The alpha was doing his best not to lose control, Oikawa could tell. He felt a thick glob of slick soaking his underwear even more.
He wished the alpha would stop holding back.
"We need to get you out of school before every alpha here can get a sniff of you."
"W-why?" The omega could barely stand on his feet now. Hajime looked at him with a puzzled look. "I m-mean... there is a w-way... y-you know it..."
"You mean I could scent mark you? So the other alphas won't notice?"
Tooru shook his head and barked out a laugh. God he'd never been shy before, much less when he wanted to fuck an alpha. But well, none of the others were his childhood best friend that he was in love with since forever.
"That won't be enough. M-my clothes are ruined, you know..."
He saw when Hajime understood. "You mean..." the alpha licked his lips.
"If we fuck, your smell would definitely cover mine."
Oikawa could practically see Iwaizumi's gears working. If his lame excuse worked, he would owe Makki for the rest of his life.
"Are you sure of it?" The alpha's voice was thicker and his pheromones were now intoxicating.
Tooru just nodded and in the next instant he was being dragged by Hajime into one of the bathroom stalls.
He barely had time to hold on to something when Iwaizumi kissed him, his arms automatically went around the alpha's neck, bringing their bodies flush together. Oikawa mewled when he felt Iwaizumi's hard cock poke his lower stomach.
Iwaizumi kissed him hard, as if he had wanted to do this for a long time. His calloused hands went to his slender waist, holding him tightly and grinding their groins together, then they went down to his plump ass, squeezing his buttocks.
Oikawa felt himself melt in the alpha's arms as their tongues met in an open-mouthed kiss. When Iwaizumi grinded their groins again, the vibrator sank further into his prostate and the omega couldn't hold back any longer.
His loud cries were swallowed by Hajime's mouth and he'd have falled when he came if weren't for the alpha's hands holding him.
Hajime chuckled low and nibbled at Tooru's trembling bottom lip. "Did you just cum?" The omega only whimpered, feeling his boxers and pants soaked and uncomfortable. "Cute."
Then Iwaizumi pushed him away a little and looked seriously at Oikawa. "You really want this, right? I mean, you're not really in heat, are you? Once we start, I won't be able to stop."
Tooru smiled and kissed him again. How could Hajime be so hot and so adorable at the same time? "I'm not in heat, Iwa-chan and I'm giving you my consent."
The alpha buried his face in his neck, inhaling deeply. Tooru purred happily with the alpha's warm breath on his scent glands.
"Then turn around for me, baby, and place your hands on the wall." Tooru was shaking when he did what he was told, Hajime's strong hands manhandling him as if he was a doll. He gave the omega a light slap on his ass. "Strip."
Tooru didn't hesitate and started to get rid of his clothes. In a few minutes he was very naked in front of his best friend, aware of his slick running down his thighs. He leaned his elbows on the toilet flush tank and curved his back, knowing too well what a great view Hajime had.
"Fucking gorgeous." The alpha growled and slapped his ass hard. Oikawa whined and shake his ass, aware of how turned on alphas could get from seeing his asscheeks jigling.
"C'mon, alpha..." Tooru reached his hands behind and spread his ass, showing his friend behind him his stretched soaked hole. "Come fuck my pussy."
Hajime bared his teeth, a low growl rumbling from his chest. Oikawa almost came again with that sound olny, it was the most sexy sound an alpha could make. Hajime batted his hands away and Tooru felt thick fingers into his hole, prodding at the vibrator still on inside him.
"Alpha!" Oikawa cried out when Iwaizumi pulled the toy out and slammed it into him again. "P-please..." the omega couldn't bear that damn toy anymore.
"Please what?" The alpha snarled into his ear as three of his thick fingers kept fucking the vibrator in and out of Oikawa. "Say it, slut." He was in a full alpha mode now, Oikawa could tell.
"P-please... I need your cock... I need a fat alpha cock and then a big alpha knot buried deep into my pussy."
"Shit," Hajime chuckled darkly, his sharp fangs scraping Tooru's bare shoulder. He finally took the toy out of Oikawa's hole. "What a mess you did here, doll."
Tooru blushed with the wet sounds of Hajime's fingers playing inside his soggy hole.
"I'd eat you out now, make you come on my tongue 'til you passed out, but unfortunately we don't have time for this now."
He heard Hajime take off his belt and unzip his pants, and looked back, watching as Hajime pulled his cock out of his boxers.
Thicks globes of slick oozed out from the omega's hole and he moaned loudly just at the sight of the alpha's cock hanging heavily between his strong thighs.
Hajime's cock was what every omega could dream of. It was long enough to make a beautiful curve upwards. The massive head was red and swollen, shining with the precum dripping from the slit. The protuded veins over the length made the omega's mouth water. It was easily 10 inches long, if not more.
The moment Tooru saw Hajime's dick, he knew he would be ruined to any another alpha. That from the moment Hajime fucked him, Tooru would be addicted to that cock.
"Oh my god, I want to suck you off... I need to suck you off." Tooru said, desperate to feel that monstrous dick in his mouth.
Hajime chuckled and held the base of his cock, stroking it lazily. "Next time, baby." Tooru shuddered with pleasure at the possibility of a next time.
Blushing again, Tooru mewled when he heard the wet, filthy sounds of his needy hole being slapped by Hajime's heavy cockhead.
"Gonna fuck you so good and hard that everyone at school will know you're my omega now. My personal slut."
"Yes-yes! I wanna be your slut, Iwa-chan. Just yours..." a harsh slap on his ass made Tooru moan loud.
"Don't fucking call me that while I fuck you."
"H-Hajime..."
"Better." The alpha aligned his head with Tooru's hole and sank into that tight heat slowly.
Tooru braced himself on the wall and the toilet flush tank as he felt his insides being rearranged to accommodate the alpha's cock. The omega's mouth fell slack, his eyes rolling back as he felt like he was being ripped apart.
"Shit." Hajime grunted, holding Tooru's buttocks open and watching the omega's hole swallowing his thick cock until he was balls deep into him, his heavy sack slapping Tooru's ass, the rim stretching impossibly wide around his girthy length. "So fucking tight."
"Oh my god, oh my god." Oikawa's insides were burning from the stretch and tears were falling down his face at how good he was feeling. "Best cock ever."
Hajime just chuckled, holding the omega's slim waist as he let him get used to his size. He caressed Tooru's beautiful back, his hands roaming over the creamy skin. Iwaizumi leaned over him, nibbling the omega's earlobe. "You're beautiful." The alpha murmured reverentially. "So fucking gorgeous."
Oikawa flushed hard as he panted. Obviously he was more than used to hearing things like that, but coming from Iwaizumi's lips, meant so much more to him.
"I-Iwa-chan thinks I'm gorgeous?" He couldn't hold back his smile, and he felt Hajime smiling against his shoulder.
"Too pretty for your own good." Tooru chuckled sheepishly and pressed his hips back.
"I'm ready."
"Yeah?" The omega nodded and Hajime leaned back again, his hands coming back to the fleshy hips, holding there tightly.
Hajime pulled out until just his head was inside, feeling Tooru's walls trying to suck him in again. He slammed back in again and picked up a stead pace, fucking the omega with long and hard thrusts.
"Ah! So good, alpha!" Tooru cried out as his body was boucing back and forth like a ragdoll. "Feels so good..."
"Fuck" the alpha chuckled "You moan like a girl."
Iwaizumi was panting hard, watching his cock barreling in and out of the omega's soaked hole, his shaft glistening with the omega's slick. He slid a hand up Tooru's spine and fisted a handfull of his silk hair, pulling it and making the omega arching his back even more.
Oikawa let out a loud, effeminate moan. He loved having his hair pulled during sex.
"You're a kinky little bitch, aren't you?" Hajime said chuckling. Tooru could only respond with high pitched moans as the alpha increased his pace, fucking him stupid, his heavy balls slapping loudly on his ass. "God your pussy feels so good, Tooru. You're taking me so well."
Oikawa was starting to feel Iwaizumi's knot forming and oh god, he was sure he'd be splitted open. But then Hajime's cock was gone and Tooru was being manhandling again.
"What..." he babbled confused.
"Don't wanna knot you like that. It'd be uncomfy for you." Hajime said and lifted him up, hooking his arms behind Tooru's knees and pressing him against the wall.
Oikawa barely registered the coldness of the wall behind him, too focused on the way he was spreading open to Iwaizumi, the way the other boy was holding him as he shoved his leaking cock into his soppy pussy again.
"Oh my god!" Oikawa's toes curled as Iwaizumi resumed his hard thrusts. His nails dug in the alpha's shoulders. "You're a beast."
Tooru knew he wasn't light by any means, but even so, Hajime was holding him and fucking him as if he weighed nothing. It was so fucking hot that the omega clenched hard around the alpha's cock, making him growl loud.
Hajime kissed him hard again and Tooru hugged his neck, keeping the alpha as close as possible.
Iwaizumi could fuck him even deeper in that position and Oikawa was seeing stars at how deep the alpha's big cock was going into him.
He couldn't smell himself anymore, just Hajime's strong and imposing pheromones. He couldn't wait to walk around school smelling like he belonged to that alpha.
Tooru was feeling the tug of Hajime's knot again and would have crossed his long legs around the alpha if he wasn't holding the omega open, Tooru's legs bouncing at each side of the alpha.
"Alpha-ah! Knot, please!"
Hajime only growled, his face buried into the omega's neck as he nosed into his scent glands.
"Gonna give you it, princess. Gonna give you my fat knot."
"Yes yes yes, breed me, alpha. I wanna be fat with your puppies." He said that even though they both knew the omega was on birth control, Tooru was just babbling nonsense, his head leaned on the wall behind him and eyes rolled back in pure pleasure as he felt another orgasm washing over him.
"Fuck yeah, princess," Hajime grunted. "Gonna breed you and give you my babies."
The omega screamed girlish as he came hard on the alpha's cock, squirting all over him and Hajime. The alpha bit on the omega's exposed throat as he came too, stuffing his hole to the brim with cum. Hajime came so much that some of his seed poured out before he thrust his knot into the omega.
Finally the omega's rim caught the alpha's fat knot and Tooru felt himself came again, his body shaking violently with his third orgasm as Hajime fucked his massive knot into him.
"Oh god!" He cried out as Hajime won't stop gushing his seed into him. Oikawa felt so full, his stomach bloating with so much cum.
Iwaizumi fucked his knot deeper into him a few more times and stopped, his fangs coming out from Oikawa's skin.
"You ok, doll?" He asked in a hoarse voice, looking at he omega's pitiful state.
Oikawa was crying and whimpering, his hands clutching at the alpha's shirt.
"Alpha, so good- feels so good" he cried, the alpha's cock still pumping cum inside his pussy.
Hajime let out a proud, happy hum. Tooru purred happily when the alpha nosed against his jaw and neck.
"I'm gonna get you to my place and fuck you until you pass out, princess." He growled. Oikawa's toes curled with the promise.
"Hnn, sounds amazing. Can't wait for it, alpha." He clenched around the knot still stucked deep into him.
Hajime pulled apart just enough to look at his own soaked pants. "Fuck, babe. You squirted all over my pants, now I need to change too." He clicked his tongue, but was clearly proud of himself.
Tooru just let out a happy purr, thinking about being knoted again and again by the alpha later.
