Summary: He never viewed himself as being in the same boat of those weak Alphas who lose control when around an Omega in heat. That perception of himself drastically changes when he runs into Omega Izuku, going into his first heat, in the schools bathroom and all that control he prided himself on goes out the window.

It was taking all of his self-control to not bite down on that tantalizing, alluring stretch of skin connecting Midoriya’s shoulder to his neck. Pressing flush to the boy’s back, his nose buried in the thick mop of fluffy hair, Aizawa hungrily sucked in his scent. His large, scarred hands clung to the slight curve of Midoriya’s hips, holding him firmly in place as he thrust roughly into his slick drenched hole. Smooshed against the stall wall, his muscular legs violently trembling, Midoriya moaned and whimpered around the bundle of underwear Aizawa had shoved into his mouth. While he wanted nothing more to hear every sweet sound that tumbled free from those plush lips, he couldn’t risk someone else hearing them. He could have used his hand to muffle those gorgeous sounds but he was already right on the verge of losing his last scrap of control – feeling Midoriya’s teeth on his skin would be his final undoing. It was Midoriya’s underwear, accidentally ripped in half during his near deranged fervor to be inside the young Omega.
Panting heavily, struggling to hold back his own moans, Aizawa distantly wondered if this was Midoriya’s first heat. The kid was right around that age. Had he taken his suppressants? If he had, they hadn’t worked. Though, the more powerful suppressants usually took a couple times before really starting to have any kind of effect. It was possible that Midoriya had taken his suppressants but they hadn’t completely suppressed his heat. He’d heard more cautionary tales than he could count about Alphas being so overwhelmed by the powerful scent an Omega gave off when he was in heat, they couldn’t control themselves but it seemed he had fallen into the dangerous category of thinking that something like that would never happen to him. It was always the weaker Alphas who couldn’t control themselves, the weaker Alphas who couldn’t walk away. The weaker ones who would just take and take and take without giving any thought to what they might be doing to the Omega.
Seemed like…if that were the case, then he was one of those weaker Alphas.
Just as he was walking out of the bathroom, Midoriya walked in. One looked at his flushed face was enough to get him riled up but it was that whiff of his incredible sweet scent had undone him. He was moving before he realized it – grabbing Midoriya by the arm and wrenching him into the nearest stall. Everything was a blur from there. One moment, he was hovering over him, a stern voice in the back of his mind demanding that he back off, that he walk away, that Midoriya was not only his student but a fucking minor – it was wrong, it was so stupidly wrong to even think about touching him, let alone fucking him, claiming him. He knew he should have backed off…and he might’ve if Midoriya hadn’t reached out to him, curling one trembling hand into the loose fabric of his shirt. Those big, teary eyes looked up at him, pleading, begging for something he didn’t fully understand. To that kid, right then, it didn’t matter that he was an adult, that he was his teacher, that he was a virgin Omega experiencing his first heat – all that mattered was that agonizing, devastating agony of wanting an Alpha so much, it didn’t matter who the Alpha was.
There hadn’t been any foreplay, no gentle build up, no kind reassurance that Midoriya would be fine, that he was going to help him. No, it was a frantic, demented scramble to tear through the infuriating barrier between them. He spun Midoriya around, pressed him firmly to the wall and reached down to grab the seat of his drenched trousers, wrenching his hand backwards to easily rip the fabric to shreds. Midoriya’s smooth, freckled skin glistered with slick. His inner thighs were drenched. His scent had already been powerful but the fabric had been muting it some – with that removed, Aizawa was slapped with a fresh wave of that irresistible sweetness. Panting heavily, he tore his own pants in his fervor to get his cock out. It was by a miracle alone that he didn’t cum the moment he touched his dick. He was already sopping wet and throbbing with a painful, needy heat. The last bit of his rationality was pleading with him to be gentle – this was Midoriya’s first time, his first heat – he didn’t want it to be a painful experience for him. He kept telling himself that right up to the point he grabbed a handful of Midoriya’s plump butt, spread him open (a harsh shudder shaking his body at the sound of Midoriya moaning loudly, his hips trembling) and pressed the head of his cock to his hole. The sight of his cute pink, untouched, virgin hole, combined with his sweet scent, the sound of his heavy, whimpering pants…it undid him.
What energy he’d been putting towards trying to be gentle was suddenly shifted to keep himself from biting Midoriya. He slammed forward without a thought, shoving his way through the tight ring of muscles to sink deep into Midoriya’s excruciatingly tight, wet hole. The first couple of screams from Midoriya went unnoticed – he was so focused on his own pleasure, he hardly noticed. It was only when Midoriya began to loudly wail ‘Sensei!’ that he managed to scrounge up enough focus to rip off the remainder of the kid’s underwear and shove it into his mouth. He settled into a hard, punishing rhythm. The bathroom filled up with the sounds of wet skin slapping together, Midoriya’s muffled wails and mews, and his own ragged pants. Sweat soaked his body. It wasn’t that warm of a day but the inside of the bathroom was sweltering. Still, he made no attempt to remove any more clothing. Doing so would mean pulling free from Midoriya. Even though it would only take a moment, his body, his mind simply would not accept stepping away. Besides…he could barely take notice of the heat over this blasting, overwhelming pleasure. He might’ve not been popular or active in any kind of social circle but…Omegas gravitated towards Alphas. Even for someone like him, who’d never really looked for an Omega to claim, had still fucked his fair share. Not nearly as many as some but…he was familiar with the experience of fucking an Omega and had even helped a couple through their heat. None of them were anywhere close to serious relationships. Hell, most of them happened just because they were young, the Omega was in heat and he didn’t have the same kind of self-control he had now.
He…he had never experienced anything like this before. This pleasure, this heat, this desire…it was almost terrifying in its intensity. Midoriya’s hole was so tight and hot. The muscles squeezed and stroked him as he moved – sucking him in even deeper, clamping down on him when he pulled out as though they were trying to keep him inside. His smaller body trembled violently underneath him. Had he cum already? Aizawa had been so wrapped up in his own pleasure that he hadn’t even thought about it. Sliding one hand around from the slight curve of Midoriya’s hips, Aizawa dipped down a little further to wrap his fingers around his plump, sopping wet, twitching length. A choked, strangled wail rippled out of Midoriya’s heaving chest. Throwing his head back, knees buckling, his ass clamping down even tighter around him, crushing his dick in a torrent of heat, Midoriya came, splattering the wall with thick, sticky ropes of white. Some of it dribbled down to drench Aizawa’s thin fingers. Panting shallowly, his head spinning with a feverish heat, Aizawa slowly retracted his hand. He looked at the splash of white across his skin for a moment before bringing his hand to his mouth. Bad, a tiny voice whispered in the back of his mind, bad, bad, don’t do it. You won’t be able to stop yourself if you do! But it was too late…he was too far gone. This little Omega…he was his. He wouldn’t give an Omega this incredible, this adorable to anyone else. His tongue dragged along his skin, gathering up Midoriya’s cum. Divine sweetness exploded over his tongue. As it slid down his throat, it warmed him like nothing else ever had. His heart jumped to an even more erratic beat, slamming so viciously against his ribs, it felt as though they might crack at any moment.
Letting out a slow, shuddering sigh, swallowing down the last drop of Midoriya’s addictively sweet cum, Aizawa stared down hazily at the fluff of dark colored hair, drinking in the delicious moans filtering out from behind the ball of cotton stuffed in his mouth, the way his small body trembled and shook against him, the heat that sucked and squeezed his cock as though his ass was desperately trying to milk out his cum. He slowly leaned down, stretching his mouth open. His thin fingers curled into the fabric of Midoriya’s sleeve, tugging it down to reveal the soft curve of his shoulder. Midoriya gasped wetly, harshly thrusting his hips back against Aizawa as he pressed his teeth to a stretch of warm, sweaty skin. There was the briefest moment, just a blink of an eye, when he managed to break through of his Alpha’s instinct with a stern command to back off. Midoriya couldn’t consent to this – not when he was this deeply affected by his heat. He knew what the adult thing to do was. He knew what he should do – what was fair to Midoriya, what was kind and right by Midoriya. He knew.
And he bit down anyway. His teeth sunk into his soft flesh, easily piercing through his overheated, sweaty skin. A burst of copper sprang across his tongue, coating his mouth in warm blood. A deranged screech of ecstasy howled through his mind, sailing down to his crotch in an immense wave of heat, pleasure and pressure. As Midoriya’s blood seeped into his mouth, he came with a snarling, growling moan, digging his teeth even deeper into his shoulder. His-! His-! This…this gorgeous, adorable, incredible Omega was his-! He wouldn’t give him to anyone-! Midoriya screamed shrilly. His head slammed back against Aizawa’s shoulder. Every muscle in his body tightened up. He didn’t have to look or touch to know he’d cum again. Panting heavily, the world a mass of wildly flickering colors, Aizawa kept pounding into him, pushing his seed deeper and deeper inside. Pulling away from Midoriya’s bloodied shoulder, Aizawa pressed his lips to his ear and snarled, “Pregnant! Get pregnant! Get pregnant!”
Midoriya wailed loudly. His eyes rolled back into his head. Thick lines of drool streamed down his throat to soak the collar of his uniform. He slammed back against Aizawa, shoving his cock in even deeper inside him. Sliding his hand up his drenched throat, Aizawa pulled the ball of fabric out of his mouth. Before he could get too loud again, he lunged in to capture that sweet, luscious mouth in a hungry, feral kiss. Sweet…sweet, so fucking sweet-! Every part of this Omega was so sweet! He…he couldn’t get enough of it! More-! He wanted more-! He wanted all of him! He wanted to devour every last inch of him! He wanted to stuff his belly full of his cum! Pregnant…he wanted to get him pregnant! To show the whole world that this little Omega belonged to him and him alone!
Pulling back from the kiss, nipping teasingly at his plush lower lip, Aizawa allowed himself a moment to fully drink in that gorgeous flushed, dazed, lewd face that Midoriya was making before stepping back. More…he wanted more…but somewhere safe…somewhere he knew that they wouldn’t be interrupted. He wanted to hear the cries his cute little Omega would make as he was fucked senseless by his Alpha. Couldn’t do that here. No…no, they needed to go somewhere safe. Regrettably slipping out of Midoriya’s tight ass (pressing a quick kiss to his temple when he whimpered, wiggling his hips in an obvious attempt to entice him back in), Aizawa got himself cleaned up then gathered Midoriya’s smaller form into his arms. Squeezing him close, he pulled the door open with his foot…to come face to face with Bakugo. They both froze. Bakugo’s bright red eyes flickered back and forth between Midoriya’s flushed face and Aizawa’s. He experienced no panic, no remorse – how could he with the sweetness of Midoriya’s mouth still playing across his tongue? He stared back at Bakugo, silently daring him to say or do anything. After a few tense moments, Bakugo’s brows lowered. A spark of rage ignited in those red eyes. His lips curled into a seething snarl. His large hands clenched into tight, trembling fists by his side. Aizawa stared calmly back at him.
Normally, he’d assume that Bakugo, being an Omega himself, was furious at Aizawa for taking advantage of Midoriya in his altered state – it was something that all Omegas feared in a way…an Alpha deciding that an Omega was his without giving any consideration to what the Omega wanted…but there was something about this rage that made him pause. Cocking his head, he stared down into those bright red eyes. It took him a moment before he finally realized what it was. Bakugo looked like he was on the verge of either tearing Aizawa’s head off or bursting into tears. Given Bakugo’s strength…Aizawa was half-tempted to activate his quirk to take his quirk away until he could calm down. This anger wasn’t directed at Midoriya. No, it was directed solely at him. If it had been reversed, he would have thought that Bakugo wanted to be claimed by him but…that wasn’t it, was it? No…this ferocious, aggressive, violent Omega…wanted the one currently cradled in Aizawa’s arms. He didn’t want to be claimed by Aizawa; he wanted to claim Midoriya. Some of the tension bled from Aizawa’s shoulders. No matter the circumstances, he could never see Bakugo as a rival. It wasn’t unheard of – Omegas pairing with other Omegas but it very rarely worked out. Their genetic makeup demanded to be claimed by an Alpha. An Omega would never be able to fulfill that desire. Not to mention, the social stigma of an Omega opting to mate with another Omega, over an Alpha. Aizawa hadn’t heard of anywhere that was accepted. Omegas belonged with Alphas, not with other Omegas. Bakugo must’ve known that…but that didn’t mean that seeing the Omega he loved being claimed by an Alpha any less painful.
Sighing softly, Aizawa stepped around the violently trembling Omega. He did honestly feel sorry for the kid. If he were an Alpha, he would just be a rival but…fuck, an Omega yearning for another Omega – there was nothing sadder than that. There was nothing he could say to make this hurt any less but he spoke nonetheless, “This pain won’t last. You’ll find an Alpha who’ll make you happy. I pro-“
“Shut the fuck up!” Bakugo snarled through clenched teeth. He didn’t turn around. Aizawa was glad – he didn’t know if he’d be able to meet his gaze, “Don’t act like you know what’ll make me happy!”
“Baku-“
“Fuck off!” Bakugo’s voice cracked. His shoulders were trembling. “Just leave me be!”
Aizawa opened his mouth to say something but stopped before any words could escape. Blowing a harsh breath out through his nose, Aizawa nodded, turned and walked out of the room. He was a few steps from the door when there came a loud boom from behind him. Midoriya, who’d been slipping off into a dazed sleep, jerked back awake with a startled squeak. His wide eyes darted around, looking for the source of the nose. Aizawa kept walking, pretending not to hear the commotion behind him. It…he wasn’t proud of this moment. He wouldn’t let Midoriya go but…he couldn’t be happy at that very moment. All he could take comfort in was that he saved both Bakugo and Midoriya a lot of pain in the long run. An Omega being in love with another Omega never worked. It would hurt the kid for a long while but…he was confident that Bakugo would find a good Alpha for him. This…no matter how Bakugo felt, it was for the best.
