Summary: When Izuku put an ad in the paper for a babysitter, the last person he expected to show up is the high schooled aged Alpha, Katsuki. To his dismay, the kid smells so damn good, just having him around for a few minutes starts making him feel like he's going to go into heat. Izuku tries to usher Katsuki out before things can get dangerous but Katsuki has a different idea of how things should go
This is a reward for a Gold Patron!

This was really, seriously bad. When he put out an ad for a babysitter in the paper, he hadn’t expected that an Alpha to answer! This was the kind of job that only other Omegas took. He’d never encountered or even heard of an Alpha, especially one as young as Katsuki, who showed any kind of interest in caring for pups that weren’t his. It had never crossed his mind that an Alpha would swagger right up to his door and say in a surprisingly deep, rough, raspy voice that made his balls tingle that he was interested in the job! Shifting anxiously in his seat, doing his best not to breathe too deeply,
(Fuck, fuck, fuck, he smelled so good! He had never met an Alpha who smelled this incredibly good before! Why was this kid’s scent so amazing?! Cinnamon, coffee, mint and something else…something masculine…the smell of an Alpha who was more than capable of pinning him down and making him his whiny little Omega – God, every time he got a whiff of it, he could feel himself getting wetter. Fuck, fuck, fuck, could he hear it? Could he hear the lewd squishes and squelches of his slick drenched ass every time he moved? Could he see how painfully erect he was? No, the table was in the way, blocking the view of his lower half but…could he smell it? Fuck…oh fuck, he had to be able to smell it. There was no way he couldn’t smell it! Fuck…fuck, fuck…he must think he was so perverted! Getting turned on by a fucking high schooler!)
Izuku did his best to remain calm as Katsuki went over his qualifications. To his surprise, the kid did have some experience babysitting – enough of it that Izuku was considering hiring him. None of his children were Omegas – Ao was a Beta, Kisu was an Alpha, and Sayuri hadn’t presented yet (far too young for that) so it wasn’t like he had to be worried about anything happening between Katsuki and one of the kids. No, what he did have to worry about was this visceral reaction he was having, caused by this stupidly attractive, incredible smelling high schooler. Sucking in a deep breath, Izuku bit down hard on his tongue, desperately grabbing hold of the pain to try to distract himself. He bowed his head slightly, staring down at his tightly clasped hands in his lap. This was so bad. What in the hell was wrong with him? It had been a long while since he’d last been with an Alpha but was he really so desperate that he was getting turned on by a high schooler?! This…the way he felt right now…it was like he was going into heat!
“You’re really red, Midoriya-san.” Katsuki suddenly said, wrenching his attention back up to him.
“E-Eh?!” Izuku jerked upright, his eyes stretched open wide. His heart lurched up into his throat. Laughing nervously, very aware of the strange, probing way that Katsuki was staring at him, Izuku shakily replied, “S-Sorry, I think that I might be coming down with a fever. Maybe, uh…we should talk another day?”
Katsuki slowly blinked. They stared at each other, underneath a dense tension of silence, then, to his relief, the kid got to his feet. Exhaling shakily, Izuku was just beginning to try to think of a way to hide his noticeable erection as well as the huge wet spot soaking through the seat of his pants when a shadow fell over him. Izuku’s head jerked up. He had just enough time to register that Katsuki was standing way too close to comfort before he found himself being shoved down onto the couch. Surprisingly large hands curled tight around his shoulders. Katsuki’s heavy weight dropped onto his midsection, pushing him further into the cushions. Bright red eyes, hazy with heat and lust, stared at him with open, demanding want. Fresh heat bloomed in his already scorched cheeks. His heart, fluttering with the speed of a humming bird’s wings, soared up into his throat. His sopping wet, painfully hard cock twitched with near deranged excitement inside his sweatpants.
“This is my fault, isn’t it?” Katsuki cooed, one of his hands sliding slowly down the length of Izuku’s chest and belly. When he reached his crotch, Katsuki pushed his hand between his trembling thighs, firmly cupping, squeezing his erect member. A choked wail erupted out of Izuku’s lips before he could stop it. A screeching, devastatingly powerful bolt of pleasure, white hot and crackling with electric energy, ricocheted up his spine, slamming into his already muddled mind with enough force to send him reeling. Izuku’s hips strained up off the couch. He unconsciously grinded his crotch against Katsuki’s hot palm. Every harsh, quick breath he sucked in was drenched with his masculine musk.
This was bad…this was seriously bad. He knew he should be doing everything possible to stop this but…but…he couldn’t find the strength! Katsuki’s other hand shoved up underneath his shirt, gliding along his bare skin to shamelessly, rough grope at his pecs. When his hot, sweaty palm brushed against his nipple, Izuku cried out through clenched teeth as an explosion of vibrant tingles rush out across the surface of his skin. His head was spinning so rapidly, he could hardly focus on anything…but Katsuki’s bright, beautiful red eyes…his handsome, flushed face were in sharp contrast to the blur that surrounded them. His body was so hot…it was unbearable! Despite the cool interior of his apartment, his body was drenched with sweat. Izuku whimpered. Could an Alpha this young seriously trigger an early heat? It didn’t seem possible but…that…that was what had happened. Heat…he had gone into heat!
Gulping hard, Izuku placed a trembling hand on Katsuki’s chest. No further…He was the adult here. He needed to act like it. Didn’t matter that he was in heat; didn’t matter that his body was aching with a kind of desire he hadn’t ever experienced before – he…he couldn’t do this with a kid! Lifting his head slightly, Katsuki shot him an irritated look. His lips curled slightly to reveal pointed canines. A shiver raced down Izuku’s spine at the sight of them. Bitten-! He wanted to be bitten-! He wanted Katsuki to bite him-! Frantically shaking his head, a little scared at just how strongly Katsuki was able to affect him, Izuku panted weakly, “S-Stop this, Katsuki…kun. I’m sorry – it’s my fault. I shouldn’t have-MNNGGH!!”
Exhaling harshly, a wide, cocky grin stretching across his gorgeous face, Katsuki lunged down to smash their lips together in a rough, possessive kiss. A loud, squealing moan rippled up his throat. What little energy he had left to resist vanished in a poof as the sweet taste of Katsuki’s mouth washed over his tongue. Eyes rolling back in his head, a dribble of drool streaming down his chin, Izuku pushed hungrily up into the kiss. Good-! Katsuki’s soft, supple lips felt so good-! His kiss was clumsy, a little overly enthusiastic but it felt so incredibly good-! Suddenly, Katsuki pulled away with a gasp. Izuku whined in disappointment, no longer able to care about his status as an adult. Katsuki! He wanted Katsuki-! He wanted him so badly, he…he couldn’t think about being a decent adult anymore! Grinning hungrily, dragging his pink tongue over his plush bottom lip, Katsuki grabbed the hem of Izuku’s sweatpants. He wrenched them down, allowing his sopping wet cock to bounce free.
“Cute…” Katsuki breathed huskily, wedging himself between Izuku’s legs. He ripped open the front of his jeans, pushing the folds of fabric aside just enough for him to yank out his dick. Izuku’s eyes widened. His heart throbbed excitedly. A fresh dribble of drool leaked out of the corner of his mouth. Big…Katsuki was so…big…his cock was gorgeous – the perfect size, shape and color. Inside…he wanted it inside-! He wanted to feel that big thing inside of him! Panting heavily, Katsuki shoved his hands underneath Izuku’s legs, bending his knees and pushing them up to his shoulders. He pushed in close, leading the bulbous head of his cock to Izuku’s slick drenched entrance. The sensation of that hot, smooth skin rubbing against him nearly sent into him a squealing, begging frenzy. For one tense moment, he thought for sure that Katsuki was going to be a big tease, making him wait and writhe before he slowly pushed it in but it quickly became apparent that he had overestimated Katsuki’s patience.
Growling loudly, his bright eyes sparking with ferocious want, Katsuki rammed his hips forward. A shaft of intense heat speared deep inside, spreading him open wide. Katsuki’s pubic bone banged against his butt, smooshing the plump globes. Growling low in his throat, his fangs bared, Katsuki clamped his large hands down onto Izuku’s trembling hips and started violently pounding into him. Throwing his head back, brows drawn together over a delirious gaze, Izuku screamed through his clenched teeth. Thick ropes of white gushed out of his violently twitching, swollen cock. He…he had never experienced an orgasm that shook his entire body to its core. Every inch of him was thrumming with a blazing, overwhelming pleasure. There wasn’t a nerve, a vein, a cell of blood that wasn’t screeching in ecstasy. Every hard bang of their bodies sent him jolting upwards. The couch rocked and groaned underneath them. Panting rapidly, hardly able to get enough breath in, Izuku clung to Katsuki’s broad shoulders, moaning, wailing and crying at the top of his lungs.
“You’re-! You’re so cute, Midoriya-san!” Katsuki ground out through clenched teeth. Leaning down, his hot breath brushing against his overstimulated skin, Katsuki slipped his tongue out his mouth, dragging it up the curve of his throat, “You smell so good-! Feels so good-! Inside-! So…s-soft-!”
“Katsuki!” Izuku squealed, dragging him in even closer. Bitten-! He wanted to be bitten-! He wanted Katsuki to devour him-! Even in his pleasure induced stupor, he couldn’t help feeling a little guilty for feeling that. Katsuki was so young…he had his whole life ahead of him to find an Omega who was far better suited for him. It was already bad enough that he was taking advantage of him like this but-! “AAUGGH!!!”
Without warning, Katsuki lunged forward, sinking his sharp canines into the soft flesh of Izuku’s throat. Eyes rolling back in his head, tongue lolling lewdly out of his mouth, Izuku came again. His hips strained off the couch. His back arched until it felt as though his spine might snap. He had thought his first orgasm might’ve cracked his brain but the immense, devastatingly loud, bombastic pleasure that smashed into him was ethereal. Moaning loudly, the sound nearly drowned out by the squeals pouring out of Izuku, Katsuki rammed his hips forward one more time to completely sheathe his length inside. It swelled up even bigger, forcing him further open then with a hard twitch, Katsuki came as well. The second that burning heat flooded into his ass, Izuku was cumming again, bucking his hips to grind against Katsuki’s belly. Inside-! Katsuki came inside-! Pregnant-! He was gonna get pregnant with Katsuki’s pups-! He…he wanted to have Katsuki pups-! He wanted his belly to be stuffed full of his pups-!
“Midoriya…Izuku…I can call you that, right…?” Katsuki breathed, gently lapping his tongue against the fresh bite wound on his throat.
“Yes…” Izuku whispered breathlessly. The afterglow was too strong to allow in any guilt or shame. He could feel Katsuki’s warmth spreading through his belly. He giggled drunkenly. He was a terrible adult but…Izuku turned his head to press a soft, sloppy kiss to Katsuki’s cheek. The kid shivered, curling even closer to him. Rising his head, he peered down at him with those beautifully bright red eyes for a moment then dipped down to capture his mouth in another possessive kiss. Izuku moaned, curling his arms loosely around Katsuki’s smaller frame. He really was a terrible adult. That, however, wasn’t going to stop him from submitting his everything to this incredible high schooler.
