General Studies didn’t have the clout of the Hero Course, so bitterness tended to fester and leak itself out in rumors and jokes. Some of it was plainly mean spirited, but Shouta felt that some of it had a grain of truth: one thing that General Studies did have that the Hero Course didn’t was a higher ratio of omegas and betas. Of course there was the exception to the rule here and there, and beta heroes weren't too unusual, but through a combination of societal prejudice and the self doubt that many omegas developed through years of being told what they couldn’t do, the Hero course filled up with alphas. As it wasn’t common for the Hero Course to date outside of its own, it was said, the whole lot of them were desperate degenerates, alphas with blue balls and aching knots, or else mounting each other like animals. At least the General Studies students were normal.
Shouta had to admit that they had a point, mathematically speaking. There were hardly any omegas in the Hero Course. Not that there seemed to be much dating going on in General Studies either, though. If there was, he was overlooked, which was fine with him. While he didn’t exactly hide the fact that he was an omega, he did use scent blockers in order to not be distracted or distracting. He wasn’t here to find a mate, after all.
---
Upon transferring to the hero course, those old jokes rattled around the back of his brain as he realized just how many alphas now surrounded him. He’d never felt very threatened by alphas before- he’d never been a particularly forward or desired omega- but combined with his lack of an offensive power, it made him more aware of his status, especially as it was used to mock him now. Rationally, that didn’t mean anything; it was just one more angle that the students who resented him being there could use to needle him so he tried not to let it get to him. He was just like a beta except for needing two days away once a month. He’d never let it make him fall behind before, and that wasn’t going to start now. He was going to buckle down and make up for the loss of one year of hero training.
It turned out that things were not as simple as he’d hoped. Within a week of his transfer he’d been descended on by two presumptuous alphas: Yamada, the loud blond he’d beaten at the sports festival who was lanky and dorky with his collection of colorful glasses and wild hair, and his friend Shirakumo, a brazen, aggressively cheerful type. Alphas that were decent people, he supposed; friendly but stupid. That was his initial impression, at least.
He came to realize that Yamada was dorky and annoying at times, but he was also sweet and sensitive, and had the most gorgeous eyes he’d ever seen on another human being. Shirakumo was witty and handsome, and kind and selfless to a fault. They- Hizashi and Oboro to him, now, weren’t just any alphas to him, not anymore. They were his friends, his best friends, overwhelming to someone who’d never felt enough affection to bestow that title on anyone else before; and they were alphas. For the first time in his life, Shouta was absolutely smitten. His entire world was upturned. He’d never in his life wanted an alpha, until he wanted two.
This came with complications, the first being that he was supposed to be focusing on becoming a hero despite his disadvantages of quirk and secondary gender. The fact that he couldn’t even pick which one he’d rather have was bad enough- how immature was that, even!- but it wasn’t even the worst of his problems. His main problem was that he was seemingly invisible to them. While he wasn’t much of an omega, any omega was supposed to be a draw, with how rare they were. However, it seemed that he was out of luck. The three of them did everything together, but not once did either of the other two cross any boundaries indicating that his omega pheromones were driving them out of their minds with lust. This was doubly unfair, since he was secretly obsessed with their pheromones. Oboro’s scent was crisp like cold air, while Hizashi’s was warmer, softer. Both were pleasantly complex, and as they were almost always together, the scents blended into something that Shouta wanted to roll around in and wrap up around himself like a blanket.
He decided to stop using his scent blockers. He began to notice that his scent changed throughout the month, growing stronger and sweeter near his heat. He waited to see if anyone else noticed.
The first complaints came during his hero instruction course. The usual idiots who’d hated him from the start told him that he reeked, how an omega shouldn’t even be allowed to fight, and how was anyone even supposed to concentrate when this slut was stinking the place up?
Shouta braced himself for a fight- it would inevitably be another day of him being beat down, but he always made it a point to get in a few good punches first- when suddenly, Hizashi growled . He put enough of his quirk behind it that the ground trembled under their feet, and Shouta’s opponent lost interest in him and focused his ire on Hizashi instead. He watched them spar- over him, he thought, triumphantly- half holding his breath until Hizashi won. He hadn’t expected to feel pleased about being called ‘this slut.’
“Thanks.” he said to Hizashi, once he’d returned from the infirmary.
“It’s good! No one talks to my friends that way.” Hizashi flashed him a smile, the wide kind where he could see the sharp tips of his retracted fangs. That stupid grin always made his stomach flip. Still. ‘ Friends.’ Shouta scowled.
----
So, Hizashi was a loss, apparently. Something inside of Shota’s chest twisted painfully at the thought of it, but there was still Oboro. Maybe it was better this way, having Hizashi make the choice for him. He was certain that he’d at least seen Oboro’s nose twitch when he was close to his heat. He just had to turn it up a notch. Oboro was in the library, looking desolately at the stack of books crowded onto his table. He shuffled a handful of index cards, then frowned again, only brightening when Shouta sat beside him.
“Where’s Hizashi?” Shouta asked, having scented him nearby. “Is he leaving you to do all of this yourself?”
“He’s tutoring.” Oboro frowned. “But you’re here now, soooo-”
“I’m not writing your paper.” Shouta snapped, knowing that it was a lie. He couldn’t get Hizashi’s scent out of his nose, even though he wasn’t in the room. It made no sense at all, unless... Shouta leaned forward in the guise of reaching for a book, and inhaled. There was now no doubt in his mind: Hizashi had scent marked him.
So it’s like that, huh? Shouta thought bitterly. Apparently it didn’t matter if he was a desirable omega or not, because it seemed like that out of all of the alphas in the world, he’d fallen for the two who weren’t interested. One more cosmic joke on Aizawa Shouta.
----
He started to use the scent blockers again after that. He didn’t want to be desired by anyone else, and his scent just called attention to him. It was easier that way. Oboro and Hizashi didn’t comment. They probably didn’t even notice. Once a month, though, Shouta could smell their ruts coming, and their pheromones would be all over each other. He shouldn’t have to be witness to this. That was the rationale he used when he’d steal pieces of their clothing for his nest. It started with a tie, but soon included a jacket, a hand towel, a pair of gym shorts. It made him feel like a pervert, but if he had to endure his heat alone, he could at least fantasize about Oboro’s strong arms or Hizashi’s golden hair. It wasn’t like they’d ever know, and they at least had each other.
Outside of his lack of a sex life, they planned for the future. In every other way, the three of them were seamless. They talked about starting an agency together, first as a joke, then as a plan that became more and more concrete. The future would involve the three of them, not just for school, but for life.
For life . Shouta sighed. He wanted that more than anything, and if it meant that his life would be celebate, well, he’d just have to deal with it. It wasn’t like he was cut out for a stereotypical omega role in society. He didn’t even think about it most of the time until their ruts were nearing, and those two would be all over each other, less discreetly than they thought.
---
Shouta opened his bedroom window. The two of them were radiating pre-rut, and he wondered if it would be enough to initiate his heat early. It was due any day now as it was, he could already feel his skin prickling with the telltale signs. He sighed as he sat, returning his attention to his screen.
“Sorry.” Oboro muttered.
“What’s there to be sorry about?” Shouta tried not to snap.
“Er... I mean, as an omega. We must stink to you.” he tried a feeble laugh.
“I can smell it, yes.” Shouta hissed.
“You can?” Hizashi looked horrified. “I didn’t think it was that bad. I mean, we’re together so much that our ruts sync up so I guess that makes sense but... I’m sorry, Shou! I’ll use blockers from now on.” he resolved.
“You don’t have to go out of your way for me.” Shouta glared down at his tablet. He could ignore the persistent throbbing between his legs. It was nothing that he hadn’t done before.
“We smell.” Hizashi pointed out. “I don’t want to bother you-”
“You’re not bothering me!” Shouta shouted, fists clenched. He took a deep breath. “You both smell... good. To an omega. But I wish you’d just get it over with already so that we can get back to normal.”
“Oh.” The two of them looked between each other, then back to Shouta.
“I didn’t think that you cared about that sort of stuff.” Hizashi admitted.
“You think I’m some sort of sexless machine.” Shouta translated, arms crossed.
“No! Nononono. But ... Shouta, you never, er. Showed any reaction to when we’d... I mean...” he faltered.
“Wait. Are you saying that you want in?” Oboro squinted at him.
“What.”
“I mean. Do you need, uh, a comfort alpha?” Oboro managed.
Shouta stared at him in disbelief. “Neither of you want anything to do with omegas, obviously . Keep your knots, I’m not a charity.”
“It’s not an offer for just any omega.” Hizashi said, not meeting his eyes.
“Just one.” Oboro clarified, turning earnest blue eyes on him. Shouta stared.
“I don’t want to be just a comfort alpha.” Hizashi’s voice broke the silence that followed. “I want you both. I want forever, like we planned.” he pouted. “We’d be good alphas, Shou.”
Shouta froze. He could easily push this away. It was an awful idea. Alphas were territorial, a single omega couldn't handle two. Not to mention that no one in society would accept that sort of situation as legitimate. It was asking for trouble. It was perverse, irrational, the kind of half baked idea that Hizashi and Oboro came up with that Shouta was supposed to shut down as the logical one.
“It’s the only rational option.” was what came out of his mouth, instead.
Hizashi unfurled like a droopy plant that was watered, his expression elated. Shouta had only a split second to activate Erasure, as he cried out and flung himself into Shouta’s arms. Oboro’s arms wrapped tightly around them both, and suddenly, Shouta was being scent marked by them both. He eagerly bared his neck, returning the gesture, a feeling a relief diffusing the frustration that had built up inside of him as laughter surrounded him.
“I want you too.” He whispered to them both. Forever. It was only the next logical step. “I’ve wanted to be yours. Your mate.”
“That’s not just your heat talking?” Oboro’s voice held a cautious hopefulness. “You’re on the edge.”
“I’ve barely thought of anything else for months.” grumbled Shouta. “And if the two of you don’t see me through it, I won’t forgive you.”
“YES!” Hizashi cheered, just loud enough to make them wince. Oboro muffled his mouth with a celebratory kiss.
“I think it’s starting.” Shouta shifted. “If you help it along...”
That got their attention. The two of them stopped to stare at him with something akin to wonder in their expressions. Maybe they really were affected by omegas after all. He felt puffed up with pride. Two alphas wanted him. The alphas that he wanted! Shouta pulled back his hair, revealing the long line of his throat. “If you mark me, It will start.” he said, a gentle nudge forward.
Hizashi was the first to move. He leaned in, rubbing his nose against his scent gland. “You’ll really be mine?”
Shouta reached over to pull off his glasses, and pressed a kiss into his wild hair. Oboro was there next, on his other side, pressing a kiss against his gland. Shouta felt two pairs of hands on him, pushing up under his shirt, teasing the burning skin. “Hurry.” he groaned. “It’s soon.”
He managed to struggle out of his shirt, and fumbled with the rest of his clothing. It was too hot, he couldn’t be free of it all soon enough. He startled as something soft and cool nudged at his legs. He fell backward onto a soft, cool cloud. It cradled him, a blessed relief on his scorched skin. Oboro and Hizashi reclined on either side of him,grinning. Oboro’s fingers teased the inside of his thigh, and he shuddered. “Please.” He tilted his chin up, leaving himself exposed. Presenting.
Hizashi paused in his nuzzling of Shouta’s neck. “If we’re going to be together, I want you both to mark me too.”
That was unexpected. Letting your omega return the bite was... very modern, though supposedly pleasurable. Letting another alpha mark you was, well. Degrading. It showed the world that you were, for lack of a better term, someone’s bitch.
“I want to be marked, too.” Oboro sat up on his elbows, looking eager. “I want to show off both of you.”
“I want to watch.” Shouta hadn’t even realized that he’d said that aloud, until they both flashed him insane grins. His heartbeat sped up as he noticed the flash of fangs that lengthened in response to their lust.
“Then we’ll give you a show.” crooned Hizashi. He draped himself backward over Shouta’s torso and lolled his head in Oboro’s lap. Oboro threaded his fingers through strands of gilded hair, and he pulled Hizashi up into his lap with one muscled arm. Shouta sucked in a sharp breath as Oboro pressed his lips just to the side of Hizashi’s mouth, then trailed down, over his pulse, settling over the exposed gland. Hizashi’s green eyes were soft with love and trust as he tilted his head back, and he let out a small cry as Oboro’s fangs pierced skin. His back arched, and his eyes fluttered closed as Oboro suckled on the gland, mixing his saliva with Hizashi’s hormones. For once, he was stunned into silence.
“Shouta.” his voice was small and reverent. “Complete me.”
Poetic sap , Shouta thought, but smiled as he leaned close, marvelling at being allowed to kiss Hizashi’s skin, to smell his skin without any barriers. Oboro’s bite had unleashed a storm of pheromones, and each inhaled breath brought him closer to the tipping point of his heat. He swirled his tongue over the gland- even his skin tasted good- and hesitated as he positioned his own smaller fangs over it. What if his bite wasn’t enough to pierce the gland? What if he just wound up hurting Hizashi?
“Love you.” Hizashi whispered, looking up at him through his pale eyelashes. Shouta bit down, hard. The taste of blood and something faintly saline filled his mouth, and he felt the first wave of slick begin to swell between his legs. Hizashi, Hizashi, all of his senses were filled with the blonde still stunned in his arms. He wanted to bite down until he was one with him, until he lost his sense of self and only knew this odd, euphoric bliss. Slowly, his jaw unlocked, letting him free, his tongue gently laving over the bite still panting for air. There was less blood than he’d expected, just two small pinpricks, obviously belonging to an omega.
Hizashi was still blissed out as Oboro pulled him close, offering himself. He gasped at Hizashi’s nuzzle-turned-bite, and closed his arms tighter around them both. Shouta was more confident this time with his bite, marking Oboro with a satisfied possessive grunt, tasting his blood, inhaling his very essence. Oboro was speaking to him now, stroking back his hair lovingly, but Shouta wasn’t able to concentrate. Slick was coating his bare thighs now, and his legs were shaking. “Need you, alpha. Oboro...” he gasped. His head was swimming with the combined fragrance of them, and he wasn’t even marked yet.
He crawled on top of Hizashi, urging his mouth to his neck. Oboro loomed over them, and sighed into his other side, seeking out his scent gland and rubbing it hard, until his fingers were saturated in Shouta’s scent. The sudden pressure on his gland felt good, and Shouta leaned into it, vaguely aware that he was practically dripping on Hizashi, making the other squirm impatiently under him. Their mouths were trailing up the side of his neck, tongues teasing his glands on both sides. Suddenly, as though it was decided between then, sharp teeth bore down on either side of his throat, and Shouta fel just a second of pain that was somehow sweetly pleasurable before his system was flooded with what felt like the strongest drug he’d ever had. He was flying, floating, half out of his body with bliss, feeling as though his very soul was merged with the two alphas. His alphas. He was aware enough of his physical form to feel his alphas against him, their breath in his hair, fingers fondling him, inside of him. He wasn’t sure whose fingers they were. It didn’t matter, not really. He needed them both, his alphas. He was aware of their erections, heavy and hot, pressed against him. Hizashi’s was trapped between him and his stomach, and he was desperately rutting, trying to find any friction. Oboro’s was just at his back. He itched with the need to be stretched and filled, something he’d always hated about his heats. Now it was an opportunity. He was never going to have to suffer through heat with a toy that wasn’t enough anymore, not with two knots at his beck and call.
A mouth sucking at his chest, scraping a nipple with a wayward fang. Another tongue between his thighs, swallowing down his slick. He shook free, and gripped Hizasi’s thick cock, hot and twitching in his fingers like it had a life of its own. He lowered his head to taste the bead of liquid at the tip, hair falling down across his face. He knew that he should pace himself, but each second without them inside of him was torture. He opened his legs wider and guided it into himself, feeling the desperate urge subside just a bit when he pressed down on it, all the way down to the beginnings of a knot. Hizashi, alpha. He wanted more. He couldn’t be content until Oboro was his, as well.
He pulled off enough to present himself to Oboro, on his hands and knees, looking over his shoulder. Oboro’s eyes widened as he understood the unspoken request. He knelt behind him, pressing into Shouta’s slick hole with Hizashi still inside from underneath him. Shouta grit his teeth as he slid into place. The strtech was something that he’d only dreamed of before, almost painful, but not quite. His slick made it easier, he probably couldn't manage this outside of a heat. He could feel them both inside of him, sliding against each other with each thrust, their pulses throbbing against his walls, against each other. He clamped down on them to make their hips stutter and shake. He knew he’d done well when he managed to knock one of them off rhythm, when he’d hear them whine his name, or call out for one another. He was their omega. It felt powerful. He’d ride out his heat properly for the first time in his life, and then when they went into rut- oh god. They’d be unstoppable, they’d need him to take their knots again and again and again, two alphas crazed with their ruts. He’d have to take both of them at once, he was the only one who could satisfy his alphas with their ruts synced- Shouta arched his back as his orgasm tore through his body, still being railed by his mates. And then, oh god, their knots. Their knots were forming, pressing him open, pressing against one another, locking them together as hot semen filled him. He could feel each beat of three pulses inside of him, one orgasm triggering another. The seed of his two mates mingled in him, locked inside at least for the next ten minutes. He panted, his mouth too dry to speak, when a small cloud pressed against his lips.
“Drink.” Oboro ordered. “It’s not much, but you need it.”
Shouta gratefully took it, and mumbled a thanks as he collapsed between him and Hizashi. He smiled down at the twin mating marks on his throat, knowing that his and Oboro’s were the same.
“This is the most irresponsible thing we’ve ever done.” he half laughed. It was always like that with the two of them. He’d lose his own serious reputation someday.
“Mm. No regrets?” Oboro asked.
“Never.” sighed Hizashi.
“Not one.” Shouta smiled. This was forever, after all. He could get used to that.
