The first thought that seven year old Bakugou Katsuki had when he laid his eyes on his new neighbor was that he needed protection. Katsuki's protection, specifically. The baby had little freckles dotting his cheeks. He looked innocent, helpless, his tiny, delicate little body giving Katsuki a sense of self-awareness he hadn't considered before. It was then that he realized the universe wasn't his, that it didn't revolve around him, that there was much more to being a person and hero than personal satisfaction. Katsuki decided he was going to be the boy’s protector, and he told Mitsuki and Masaru as much. Of course, they encouraged his noble proclamations. Midoriya Izuku became Katsuki’s personal motivation for becoming a hero.

That feeling intensified, at age 11, when Izuku was diagnosed quirkless.

“You’re useless, Izuku. No, Deku,” he said. Although it sounded malicious, Katsuki thought of the nickname as showing fondness. Because Deku knew he didn’t mean it. He had to protect him. That was just the way things were. “You’re useless, so you should rely on me, okay?” Katsuki had held his hand, then. It was so little. Deku was so fragile. Like glass. He needed protection. He needed Katsuki. Katsuki enjoyed being needed. He liked teaching Deku things, enjoyed tutoring him, playing with him, teasing him. It was too fun. Katsuki felt akin to an older brother.

When Katsuki was 13, he presented as an Alpha. Not to anyone’s surprise. He was vicious during his first rut, nearly destroying his house and giving Mitsuki a number of migraines. She complained endlessly to Inko about it, since they were best friends. When Katsuki appeared to be manageable, Deku was permitted to see him. The little 6-year old immediately ran to him, crying about the people who had been mean to him on his way home from school while Katsuki had been away.

“I need you, Kacchan,” Deku had sobbed. “I need you to help me and protect me from all the mean people.”

The boy’s crying strangely put him at ease, and Katsuki assumed it was because of his intense need to protect him. The intense need to shield him from the cruelness of villains, of people, of any kind of threat.

“It’s okay, Deku. I’m gonna protect you. Always. I’m gonna grow up and be a really cool hero just for you, okay?”

Mitsuki was still always surprised when Katsuki spoke to Deku like this. So soft and caring, with the kind of gentle look he never showed around his classmates, or teachers, and rarely his parents.

“Okay…” Deku nodded. “Promise?”

Katsuki ruffled the boy’s already unruly hair. “Promise.”

Katsuki had an intense need for Deku himself, for his comforting presence, for making Katsuki feel needed, wanted. Deku was genuinely amazed by everything Katsuki did, and Katsuki appreciated that more than he was willing to admit. Everyone expected him to be amazing, because of his quirk. But Deku still congratulated and praised him for the little things that went unnoticed by others. Katsuki cared for him more than he cared to admit. He cared so much that he was straining against his primal urges and keeping a fond smile on his face even though every fiber of his being was telling him to attack. He cared so much that Deku showed up in his dreams that night, looking indescribably wonderful.

Katsuki bolted upright, panting in his bed, confused and frustrated and scared. Why would he have a dream like that? A dream like that about Deku, of all people? And it was then that Katsuki realized why. Deku must be his. His omega. And his body must have realized that. Or something. That was why he was hard. Why he'd seen Deku look like that in his mind.

Katsuki had to be Deku’s Alpha.

Otherwise, the dreams he had would mean something very, very, bad. Something unbecoming of a future hero. But he was fucking hard and he couldn’t stop the image of Deku from flooding his mind as he grinded against his pillow, desperately searching for release.

How could he tell anyone about this? He couldn’t. He wasn’t going to say jack shit to anyone about this, otherwise they’d keep Deku away from him, and Katsuki needed Deku, he needed him. He needed to see him smile, he needed to see him laugh, he needed to see him crying, he needed to see him writhing under him— No. No. No! Katsuki couldn’t think that. He shouldn’t be thinking about it, at all. Deku was a fucking kid. Katsuki didn’t see him like that. He couldn’t. He didn't. But the alpha in him said otherwise as he growled into his mattress, rutting helplessly against his pillow, knot growing painfully. It hurt, it fucking hurt. He wanted to be buried inside something. He needed it. He craved it. He craved Deku.

Deku's tiny little body, under him, feeling good from him, precious and cute like the good boy he was. Deku, and his beautiful little mouth, gasping, moaning. Deku, crying his name, moaning "Kacchan" for him, being so good, so good.

Katsuki moaned, snapping his hips forward, faster, desperately.

Deku and his tiny little cock, hard, bouncing with every thrust into him. Deku, tightening around him, face euphoric.

Katsuki growled, picturing himself burying his swelling knot in the tiny boy.

Deku... Deku... Deku!

Katsuki's vision blanked as he came, and finally he calmed down enough to get through his day normally.

Somewhat normally. As normal a day as one can have after fantasizing about a six year old.

Katsuki changed a little, after that. He hadn’t thought presenting would do so much damage to him, physically or mentally, but it did. He wasn’t the same person as before, and he couldn’t be. He felt jealousy rise within him whenever Deku talked about playing with other kids at school. Especially other boys. Katsuki knew, rationally, that six year olds were no fucking threat to him, but he couldn’t contain his possessiveness over Deku. He wanted to own him. And he would, whenever Deku presented. Katsuki would make sure of it. He had to, or else it wouldn't be good for him. He might go crazy and sabotage his entire career if he touched Deku and Deku didn't want it.

The boy was sitting in Katsuki’s living room, watching TV, as he often did while waiting for Inko to come home.

“Hey, Deku.”

He beamed. So stupidly bright. Like the fucking sun, that boy.

“Yeah, Kacchan?”

“You’re my best friend, right?” he asked.

“I am??! Really??? You’re my best friend too, Kacchan!! My bestest friend in the whole world!!” Deku hugged him tightly. “I love you more than everyone else, Kacchan! But don’t tell mom.”

“I won’t, dummy.” Katsuki threw an arm around his shoulder and gave him a noogie. He kept his arm there, around his shoulder. “You’re so tiny for a six-year old. Hurry up and grow up already, idiot.”

The words weren’t supposed to mean anything. They shouldn’t have meant anything, but Katsuki was impatient at this age and he wanted to claim the freckled boy already. But he’d have to fuckin wait. Like a loser.

“I’m gonna be big and strong like you, Kacchan!”

Katsuki didn’t really want him to get big. Or strong. He liked how helpless Deku was, because it just made him rely on Katsuki more. As he should. Katsuki played with his hair mindlessly. It was comforting, and Deku had such a cute reaction to it. It made him sleepy, most of the time.

“You don’t have to be big and strong,” Katsuki told him. “‘Cause I’ll be there to protect you.”

//

Katsuki whispered to Deku often, about things he’d learned. Deku was always so happy to learn new things, he sucked it in like a vacuum, though Katsuki could never tell if he actually processed and registered the information, or if he just liked hearing Katsuki talk. It was rather cute, either way.

“Ruts are honestly terrible, you know. I just never felt satisfied, even though I’d done it so many times,” Katsuki sighed. He knew the topic wasn’t exactly appropriate to tell a ten-year-old, but it was about fucking time Deku learned about this shit. Knowing Inko, she’d shield him from it till he was fuckin' 16 or something. Besides, Katsuki wanted Deku to think about him. To really think about him, beyond those dumb pure thoughts of ‘somebody to admire’ and ‘a best friend’. Deku was far from Katsuki’s ‘best friend’, but what else was he gonna tell the ten year old that fuckin’ loved him? He needed Deku to keep relying on him, to keep clinging, so no damn dumb kids would try to steal him away. So Deku would learn to want Katsuki and no one else. Like how Katsuki felt about him.

“What do you mean by ‘it’, Kacchan?”

Katsuki grinned. His assumption had been right. Of course it had. “Oh, Deku, you’re so stupid. Didn’t Auntie Inko teach you yet? You’ll present in a few years. Anyway, I meant masturbation.”

Deku finally stopped working on his homework and looked up at Katsuki, who was flipping through his assigned reading for his literature class and not really paying attention to it. It was hard to, when the object of his affections and immense sexual frustration was sitting in front of him. Especially since they were alone. Finally, those big doe-eyes were concentrated on him. It was more gratifying than his stellar grades, having the little boy’s eyes trained on him. The sheer curiosity on his face was adorable, the stupid thing had no idea what he was getting into or what he was asking about or that it was inappropriate, maybe, for a boy his age, but Katsuki would teach him and happily so.

“'Mas-tur-ba-tion'?” he repeated, sounding out the word curiously.

“Yeah. Y’know, stroking your cock until it cums. Or fucking into an onahole.” Katsuki could tell Deku’s brain was running a mile a minute, trying to process all these new terms, trying to figure out what the hell they meant just by using context clues. But Katsuki knew he wouldn’t be able to figure it out, so he’d ask again. And Katsuki was more than happy to enlighten him.

“What’s a ‘cock’? And what do you mean by coming? Like coming home? And an ona...ona…?” He trailed off, unable to remember the term.

“Onahole. Your cock is just a ‘big-boy’ term for your little peepee, idiot. Y’know, your pe-nis," he emphasized, sounding out the word slowly to make sure the little boy knew what he was talking about. "You hold it in your hand,” Katsuki said, making a circular shape with his hand right above his crotch, “And you stroke it up and down like this.” He demonstrated.

Deku watched him with wide eyes and it was probably bad that Katsuki wanted to demonstrate for real in front of him. Katsuki nearly got hard, just having the boy watch him mimic the motions of masturbation.

He wanted to show him so badly, show him what a matured cock looked like, show him how good it was to touch yourself, have him stare in awe, wanted to watch as heat pooled in his stomach, a foreign feeling but a good one. He was almost mad he wanted to be a Pro Hero because he had to abide by society’s rules for shit like this. Deku was gonna be his mate, anyway, who the fuck cared if he was ten right now? They’d be mated for life eventually.

“If you do it long enough, you’ll feel like you have to pee. And if you let it happen, it feels really good. White stuff comes out. It’s called semen, but a slang term for it is cum. C-u-m, not c-o-m-e. Hence the term cumming. But the other one works too.”

Katsuki had to pause his mental train of thought, because god, it was not moral. Well, not to society at least. Despite Omegas being fuckin’ Alphan property it was still fucking ‘wrong’ to have sexual desires to anyone under sixteen. Like, fuck, Katsuki was literally going to own Deku in a few years, why the hell should he have to wait?! Katsuki closed his eyes and sighed. Inko or the hag would refuse to let Katsuki see Deku ever again if he was caught getting hard. It took a lot more effort than he wanted to expend.

“Oh...what about the other part?” The nerd’s quiet voice brought Katsuki back to reality.

“What do you mean?”

“You know, the…” Deku looked down, twiddling his thumbs like a fucking shy shoujo manga heroine. “...The part my mommy has.”

“Oh. Girls usually use their fingers. Why do you care?”

Deku blushed and went silent. Katsuki immediately assumed the worst.

“What, you got a little crush on a girl, Deku?” Katsuki had to hold in his rage. He didn’t know who the fuck this girl was, but he was already ready to tear her apart.

"She wouldn't like a weak little boy like you, you know."

Deku looked up at Katsuki like he was gonna fucking cry.

“N-No, um… My mommy said not to tell anybody, but I...I trust you, Kacchan.”

Well that was music to Katsuki’s ears, ‘cause he knew damn well that Deku should not be trusting him, of all people, but it didn’t really matter to him. Deku already belonged to him, in Katsuki’s eyes. It was a relief that he had Deku’s trust. Thank the gods or whoever the fuck was up there, watching over him. Must’ve been Satan, considering he was consistently left alone with the object of his affections who also happened to be an underage boy that Katsuki couldn’t fucking wait to ruin. Katsuki knew he wasn’t good, at this point. But who cared? They let him get away with everything, because he was number one in everything he did. Except maybe having morality.

“Well, spit it out, nerd,” Katsuki said, wanting him to get to the point already.

Deku crawled over to him and got in Katsuki’s face, those stupidly beautiful eyes nearly making Katsuki lose control. It took everything in him right then not to fucking rip the boy’s clothes off and breed, but it was because his rut was coming on and absolutely not because Bakugou Katsuki was any sort of degenerate type of human being.

“Um…..I have both parts. But I know I’m a boy, ‘cause I feel like a boy.”

The word ‘boy’ made Katsuki’s dick twitch, reminding him of how young and vulnerable Deku was.

“Oh, you’re intersex, then,” Katsuki replied, nonchalant. The boy probably wanted him to be cool about it, to not make a huge deal, so he wouldn’t. He had to keep his trust. He had to show Deku that Katsuki was one of the only people he could trust, that he was one of the only people who would accept him. He had to make sure Deku knew that Katsuki accepted him and that Katsuki cared for him but that others wouldn’t.

Deku nodded, and the tears in his eyes started overflowing.

“Goddamnit, Deku, it’s not a big deal! Don’t be such a baby about it. It’s not like it changes anything.” With the exception, of course, of Katsuki’s fantasies. He’d have to do a little update and upgrade on those. Fuck, Deku probably had such a cute and tight little pussy. And he was so small now, so helpless, that if Katsuki wanted to he could justー no. No. Unfortunately, Katsuki had a promise to keep to said nerd, and a career to pursue that would very much be jeopardized if he took advantage of this situation. At least, took advantage in a way that would be an obvious criminal offense.

He pulled Deku into his lap as he cried, stroking his back to comfort him.

“It’s okay, Deku. I’m here for you and it doesn’t matter to me what you have down there. And you’re right, you’re a boy because that’s how you feel and it’s what makes you comfortable. Other people might say rude shit or tease you, but I won’t. Not like that. And if you get bullied, just tell me and I’ll give them a scare, okay?”

Deku gave Katsuki a weak noise of affirmation and Katsuki kissed his head, breathing in his scent. Although he hadn’t presented yet, his scent was naturally sweet and comforting to Katsuki, something like warm vanilla. Maybe a hint of cinnamon, fitting to go with his skin that looked like it had been dusted with it. Deku sighed against him, and Katsuki felt warmth blossoming in his chest. That was just further proof to him that Deku was his mate. Nobody else could have made him feel something this incredibly soft.

Katsuki might’ve sounded indifferent or unbothered, but it made him happy that Deku trusted him, and Deku, the stupid crybaby, was obviously relieved now that his ‘best friend’ knew.

“You have to be careful when you’re making friends, Deku,” Katsuki whispered in his ear, unable to stop the slight sensuality in his tone from slipping out. “Not everyone is like me.”

“I know, Kacchan...I’m careful. I only have two friends.”

Two? Who the fuck was this other person? Deku didn’t need anyone but him.

Katsuki hummed. “You okay now, baby? Not gonna cry anymore, right?”

Deku pouted, but wrapped his arms around Katsuki, not wanting to move.

“I’m not a baby, I’m a big boy.”

Dumbass, That wasn’t what Katsuki meant.

“You’re right, Deku, you’re a big boy now, learning about big boy things. Are you gonna go home and touch yourself like I taught you?” Katsuki cooed. “You gonna do big boy stuff?”

Deku bit his lip, unsure. “I...I dunno, Kacchan...it sounds weird…”

“It’s not weird, Deku. Everybody does it. Auntie Inko is just embarrassed to teach you. But I’m sure she does it too, once you’re asleep...thinking about Uncle Hisashi. Your mom’s never made any funny sounds at night? You’ve never heard her call your dad’s name?”

Katsuki didn’t exactly mind the image his words were conjuring. Inko did birth the boy who occupied Katsuki's thoughts so often it would be considered an obsession if he didn't know how to contain himself and wear his normal-person suit.

Deku shook his head.

“...I don't think so...? Sometimes if I can’t sleep, and it’s really late, I hear stuff, but…”

Katsuki chuckled.

“You 'hear stuff' because Auntie Inko is making herself feel good. Don’t you wanna feel good, too, Deku?” Katsuki purred in his ear.

“Y-Yeah, but…”

“Don’t be scared, nerd, it’s just your body. I promise you’re gonna like it. Have I ever lied to you?”

Deku shook his head no.

“I think you should try it, then. You know, if you’re a big boy like you say you are,” he teased, egging the boy on purposefully, knowing that Deku never backed down from a challenge, no matter how useless he was.

“I’m a big boy!” he retorted, insistent.

Katsuki smiled, positive that Deku was going to touch himself that night. Idiot...stop making things so fucking easy.

“Good. I know you are. Anyway, like I was saying, ruts fuckin’ suck,” Katsuki said, circulating back to his original topic, in part because he wanted to complain and in part because he wanted to impart more wisdom onto Deku, and it was better he learned about it first-hand from someone he trusted than a fucking textbook.

“I’ve heard of that before, but I don’t really understand what they mean.”

Katsuki sighed, feigning exasperation to mask his exhilaration. He really shouldn’t be getting so high off of teaching Deku about puberty and sex and all that shit, but he did, and he figured he might as well roll with it. Besides, there were no rules against teaching an underage kid about these things, just acting on the desires...which Katsuki wasn’t...for now, at least.

“Alphas go into ruts, omegas go into heat. You breed or you get bred, Deku,” Katsuki said, purposely not elaborating further on the subject. “Bet you’ll be a fuckin’ omega, useless as you are.”

Deku protested. “No way! I’ll be a super cool Alpha just like you, Kacchan!!”

Katsuki already knew that Deku would be an Omega. It wasn’t like it took a fucking genius to guess by his submissiveness and eagerness to please. He might as well have had the symbol tattooed on his freckled face. His Omegan personality stood out as much as the stars on his cheeks.

“Alright then. You wanna bet on it? Just twenty bucks or something,” Katsuki leaned forward, provoking him. “Y’know, since you’re a fucking wimp.”

Deku scrunched his face in defiance. “I’m not a wimp!! I’ll bet my whole life on it, Kacchan! I’m gonna be an Alpha, and then you’re gonna buy me ice creams every weekend!”

Katsuki laughed. Of course his stupid little pea-brain couldn’t think of wanting anything past a lifetime supply of ice cream. God, he was so fucking naive. And so. fucking. easy. “If you say so, nerd. If I win the bet, would you really give me your life? You can go with something more tame. If you’re a pissbaby, that is.”

“I’ll really do it, I swear! I’m not a coward!”

“Mmm, fine then. I look forward to it, Deku. Not like you can do anything without me, anyway. Guess it wouldn’t make much of a difference if your life was in my hands," Katsuki stated. "I always gotta fuckin’ protect you from pervs and shit. You just look like villain bait. A lot of bad people are gonna wanna do bad things to you, Deku." The blonde lowered his voice, making it sultry as he continued to hold the boy in his lap, still rubbing his back for comfort. "They might wanna hurt you...or touch you in weird places. They'll try to tell you it's something that feels good, but they'll be lying. You shouldn't let anyone touch you. Only the people you trust," he said, putting emphasis on the word 'trust' since he now knew he had it. Completely. "Don't let anybody touch you."

It was a warning, but it was also a command. There was an unspoken "except me" at the end of that phrase. He wasn't sure if Deku could discern that, but it didn't matter. It was enough. Deku would listen to him, because he listened to everything Katsuki said. He stroked his hair again, idly, before whispering,

"You're safe with me."

Deku was far from it. But he didn't have to know that.

Katsuki played with his hair until he fell asleep, listening to Deku's quiet breaths. Inko wouldn't pick him up for another hour or so. He had time. Katsuki felt his cock growing again with the warmth of Deku's body against him, the feeling of the boy straddling his lap turned him on and weakened his resolve. It wouldn't be illegal if he didn't get caught.

Katsuki tentatively placed his hands on Deku's hips, feeling guilty about how large his hands looked around his tiny waist. But his arousal by the difference outweighed that guilt. Deku was so small, so fucking fragile, and Katsuki's cock would most definitely split his cunt open. It would suck him in so fucking good, squeeze him perfectly. He inhaled Deku's scent. It was very subtle, since he hadn't presented, but Katsuki loved it anyway. Katsuki gripped Deku's waist a little tighter and pressed him down, forcing Deku's crotch to rub against his own. He didn't even stir. Katsuki knew that Deku slept like the dead. He wasn't going to wake up. Katsuki bit back a groan as he dug his fingers into Deku's ass, which was far too plump for a ten year old to have. He grinded his hips upward, cock straining against his pants.

Katsuki knew what he was doing was bad. He knew it, but he couldn't fucking stop. It was Deku's fault, really, for being so fucking cute. For telling Katsuki he was trustworthy, for saying he loved him. Was that not the same as begging to be fucked?

Katsuki grunted and thrusted harder, imagining Deku waking up to him doing this, those adorably big eyes wide with confusion and then shutting in pleasure. He'd tell Kacchan he feels weird, but would eventually start grinding his little cock against Katsuki's, unable to go against those primal desires. Mmm, Fuck, that would be so hot. He imagined Deku taking off his pants, showing Katsuki his little pussy and how 'weird stuff' was coming out. Katsuki would feign concern, tell him he needed to be cleaned up, then fucking give that little boy the best head anyone's ever gotten from him. At this point, Katsuki was in pain from how restrictive his pants were. He had to move Deku so he could unzip them before they could fuckin' burst. He moved in front of Deku's sleeping face and grabbed his cock, moaning as he stroked it. Fuck, Deku was so hot. He could see the boy's little cock straining against his own pants from when he'd rutted against it. Katsuki was so fucking terrible, but ohhh did the filth of it all feel so good. He was seventeen and jerking off to a fucking ten year old, and nobody knew. Nobody would know.

"Fuuuck, Deku. Gonna— gonna fucking breed your little pussy, you slut," he hissed, fangs sharpening as he drew closer to his climax. "Such a good omega for Kacchan. Hnngh!"

Fuck, he was gonna cum. Shit, but where? He couldn't stain the boy's clothes, nor the couch he was sleeping on. He couldn't leave any evidence.

And then, like a sign from the universe, Deku's mouth fell open and Katsuki had a divineー or rather, sacrilegiousー revelation. Grinning, he forced Deku's mouth open further and pressed the tip of his cock into the boy's mouth. The fact that he didn't even stir pushed Katsuki over the edge and he moaned a deep, guttural noise as he came, mind going white and making him think he had ascended to a higher plane of existence. How the fuck could something that felt this amazing be so wrong and immoral? If Katsuki had a religion it would be this. The only thing he would worship in his lifetime would be Deku. Deku swallowed his cum reflexively, face scrunching in distaste as he swallowed, but he never awoke.

Katsuki got up, stuffed his cock back into his pants, and zipped them up before sauntering to the kitchen and pouring a glass of juiceー Deku's favorite. He walked back over to the sleeping boy and took a sip, before taking the boy in his arms and kissing him, making him drink the juice to mask the taste of Katsuki's fluids. After he'd given Deku about half a glass, he felt satisfied that no one but him would be any wiser about what disgusting things had just transpired.

The universe must really fucking love him. Not that he had any complaints, though.

//

Katsuki was getting impatient. Deku was already fucking fifteen, and Katsuki was well-established in his career as a Pro Hero, somewhat infamous for remaining single despite being an "attractive, young bachelor" that was "all the rage" nowadays. Yes, he was all the rage because his mate hadn't fucking presented yet. Katsuki had waited long enough, he knew Deku wanted him, he knew Deku was well-aware now that the way Katsuki touched him went beyond what was normal for friends, and he knew Deku didn't hate it. He knew Deku liked it, even, with the way he clung to Katsuki when he was being saved. He'd taken every single call about the curly green-haired freckled boy who was prone to abduction. Katsuki couldn't blame the villains, Deku was quirkless and weak, and something about him screamed "ruin me". Katsuki could empathize with how they felt. But the two hadn't spent time, real time together in a few years. Katsuki was busy.

He'd really only been able to see Deku when he needed saving.

He knew exactly when Deku had started masturbating while thinking of him, because there was a day he needed saving at thirteen and he hadn't been able to stop blushing for a single second as Katsuki had held him in his arms. Katsuki had figured he'd started touching himself soon after Katsuki had told him about it, but he'd been too young and unknowledgeable to know anything about fantasies. He probably hadn't even been aware that his feelings for Katsuki had been anything but admiration until he'd had a sex dream about the older man.

Of course, Katsuki had anticipated that. He'd planned it carefully, many, many years in advance. Katsuki knew he wasn't a good person, but he was doing good things and that was what people saw, it was all people cared to see because it protected their reality. Katsuki didn't have eyes for anyone but Deku, but he'd slept around because well, his dick couldn't wait. And he had to at least wait until Deku presented to do anything substantial. Physically. He'd already done enough damage to Deku mentally from… years upon years of grooming, but… no one needed to know that. Deku himself didn't need to know. It would break him, crush his soul. And Katsuki couldn't have that. If Deku's soul were to get crushed, it would have to be by someone else, so that Deku would come running into Katsuki's arms and never trust anyone else ever again.

Katsuki wasn't one to drink, really, but he poured himself a scotch and sipped. Deku was coming over. He was going to spend a week here, at Katsuki's home. Inko was visiting Hisashi in the States, and she didn't want to risk him being around foreigners. Inko's overprotectiveness was convenient for Katsuki. It meant she was careful about who she allowed in Deku's life, and as far as Katsuki knew, he was the only person his mother had fully approved of. Inko practically gift-wrapped Deku for him, never thinking twice about his attachment to Katsuki, nor the reason he was so clingy and touchy-feely with him. It was because Katsuki had taught him to be, made sure he knew it wasn't weird to cuddle with your friends and sit in their lap, because fuck toxic masculinity, right? He had to set a good example!

Katsuki hadn't seen Deku or talked to him since his last abduction a year ago. Knowing him, he probably hadn't grown much. Katsuki missed those giant, green eyes.

He turned on his television and decided to start on dinner. Deku would be here by the time it was finished, so they'd be able to eat together. He smiled to himself as he chopped vegetables for Katsudon, hoping Deku would appreciate that Katsuki was making his favorite food for dinner. To be honest, he wasn't exactly sure what he was going to do with Deku while Inko was in the states (besides fucking him), he didn't know what it was that 15 year olds did nowadays. Other than school, of course. As a hero, he wasn't sure what it was like for other people.

Deku was in the support course at U.A., so he'd at least fulfilled some part of his dream. Supposedly there was some costume or gadget-making prodigy girl there now by the name of Mei. She might be a prodigy, but Katsuki knew his Deku's hard work wouldn't lose out to her genius.

Maybe he'd put on a movie, something Deku had liked as a kid, just for old times sake. But he also had the option of "allowing" Deku to watch an R-rated movie with him. For….fun, of course. So he could watch the boy squirm.

He hummed a little tune to himself as he prepared the broth, taste testing it. It was all good. Katsuki started preparing the udon and tossed in the vegetables, content. His omega was almost here, and he was happy.

A timid little knock at the door told Katsuki his boy was here. He took off his apron and set it aside, choosing to walk over slowly, just to make Deku squirm in anticipation.

“Hey, Nerd,” Katsuki greeted, that ever-present cocky grin gracing his lips.

“H-Hi, Kacchan, thanks for having me.”

And have you, I will, the blonde thought.

The two of them ate dinner in a sort of comfortable silence. Katsuki never pressured Deku to talk, and the poor high schooler was too nervous to really say anything, just continuously stealing glances at Katsuki and squirming in his seat. So obvious.

“TV?” he asked. All he received in response was a nod. So submissive.

//

Deku was sitting on Katsuki's lap, squirming around in a way that made Katsuki let out a gruff "stop moving" because much longer and he'd lose his rationality to lust, especially when Deku was wearing tiny All-Might shorts. Deku obeyed him, as he always had.

God, did it make Katsuki want to demand he just strip naked and suck his cock, just to see if he'd still listen.

"So I heard you still haven't presented yet. Are you worried?"

Deku blushed and looked down.

"Mm," he affirmed, being adorable by using sounds instead of words.

The hairs on his head just looked so perfect for pulling. Katsuki wanted him to present soon, hopefully while he was here for the weekend, so Katsuki could finally claim what was his.

"Have you tried to induce it? By masturbating?"

"K-Kacchan!!"

Deku rubbed his thighs together, pouting. He averted his eyes from Katsuki's gaze, clearly embarrassed.

"...But yes. I keep trying to masturbate, but I never have any reaction even if I'm using items that smell like an Omega or an Alpha."

Katsuki was enraged. Deku had used items that belonged to other people to help him masturbate? Of course the shitty extras' scents wouldn't work.

"What if I'm quirkless and a beta? Then I really wouldn't belong."

Katsuki mused for a moment, trying to think of the right words to say. What Deku wanted to hear, and what would turn out the best for him.

"You'll always have a place to belong with me, Deku. Even if you're a nerd. And, for advice…it might help to have someone in mind when you masturbate."

Deku slowly raised his head and met Katsuki's eyes, his gaze unwavering.

"I always have someone in mind," he stated.

It was obvious to Katsuki that Deku meant him, but he chose to play dumb. He couldn't exactly give away that that had been his intention.

"Oh, really? That Mei girl, maybe?"

Deku flushed and looked away again, having lost his temporary confidence. Katsuki found it adorable, that he was still so easy to embarrass after all this time.

"I... I'm not telling…"

"Alright, nerd, keep your secrets. You still holding on to the hope that you're an Alpha like me?"

Deku opened his mouth, then closed it. He was unsure of how to answer. He rubbed his pinky with the thumb and forefinger of his other hand, one of his many nervous ticks that Katsuki had picked up on. He was pouting again, practically begging for Katsuki to kiss him with his lips puckered like that.

"I… didn't forget," was all he answered with.

"Oh yeah?" Katsuki asked, smirking. "Still willing to bet that much?"

Deku was quiet.

"I told you, I'm not a wimp, Kacchan. Don't forget it goes both ways."

Katsuki hummed. It did go both ways, but there was no way in hell Deku could possibly be an Alpha. Not one single chance.

"I know," he responded, succinctly responding to each of Deku's statements with only two words. "Come here."

Katsuki patted his lap and Deku obediently crawled to him, settling down and leaning back into Katsuki like it was the most natural thing in the world, when really, it was very, very wrong. Katsuki wrapped his arms around Deku and leaned down to breathe in his smell. Deku didn't even flinch, this was a normal occurrence for them. Katsuki had conditioned Deku to think that there was nothing wrong with it. By now, he'd learned. He'd already be aware that it was wrong, at this age. So Katsuki knew, at this point, that Deku wanted it. He heard it in the way Deku's breath hitched when he trailed his fingers up his thighs.

"'S been a while since I've seen you, Deku."

"Y-Yeah, it has…"

"You found anybody else you trust, yet?"

Deku shook his head no. He knew what Katsuki had meant. He'd been asking if Deku had allowed anyone else to touch him.

"Mm," he nodded, bringing his head forward to bury his nose in the crook of the teen's neck. "You tried getting to present by having a partner?"

"Ah, uh...no…"

"Huh. I think that might be helpful."

Katsuki continued running his fingers up and down Deku's thighs, pretending not to notice the change in his breathing.

"W-Well, there isn't anyone I like, really, so I haven't…"

Katsuki pressed his thumbs against the skin of Deku's inner thighs, listening intently as the boy gasped and promptly bit his lip.

"Really?" the blonde asked, letting his voice slip into seduction. He leaned forward until his lips brushed against Deku's ear. "No one? At all?"

Deku shivered.

"N-Not really…"

Katsuki clicked his tongue.

"So what, then, you're gonna get some random extra to help you out?"

Deku shook his head no.

"Then what about me?"

Deku bit his lip, refusing to respond.

Katsuki looked over Deku's shoulder.

"What about you, Kacchan?"

Brat. Smart-mouth. He knew what Katsuki was asking. Trying to get him to say it.

"What, you trust me, don't you?"

"I do."

Of course he did. Katsuki didn't spend the last near-decade grooming Deku for him to not trust him.

"Then I could pretend to be your 'partner', and you can think it's whoever you want it to be."

As if there's any possibility it's not him.

Deku hesitated. "B-but…"

Katsuki sighed and laid back against the couch.

"What? You used to kiss me all the time! You just couldn't get enough of me, still demanding I take naps with you and cuddle you when you were already eleven. That was only a few years ago."

Probably some of Katsuki's favorite times with Deku. Nap time was always the best. He loved grinding his hard cock against the boy's ass, loved playing with his nipples as he slept. Katsuki had used Deku's mouth as a cumdump countless times. Poor boy must've thought he just had the worst morning breath. Fuck, he was getting hard just remembering it.

Deku grabbed Katsuki's arms and wrapped them around himself, before sinking backward into his chest and letting out a content sigh.

"That was different. I hadn't hit puberty yet. It didn't…” The freckled boy fiddled with his hands. “...have any meaning then."

"So it has meaning now?"

"Well, yeah, now I know what it means. I trust you, so I'd trust you with this and my body, but...I can't do it if it doesn't mean anything to you, Kacchan. Because to me, kissing and touching and stuff… they mean a lot to me. So I don't want to feel like I'm just an experiment for you to see if you can induce a heat or rut in another person."

Katsuki nuzzled his nose into Deku's neck.

"It wouldn't be an experiment, shitty nerd. I just want to help you. 'Cause I know it worries you and 'cause I care." And he did care! He really did care about the cute little boy in his lap.

He cared about breeding and owning him.

"I know you care, Kacchan. You're one of the only people who do."

He cared about keeping Deku for himself.

"Mm." Katsuki didn't want to confirm nor deny Deku's statement. He didn't want Deku to feel unloved but he wanted him to know that he only really had Katsuki. Katsuki was all he needed.

"Well," he said, "I won't force you." He couldn't. Deku had to ask for it, after all. Explicitly, so there'd be no question of his 'consent'.

Deku sighed once more.

"I know that, silly."

"But don't you wanna make me happy, nerd?"

Katsuki knew exactly how unfair that question was. He knew it put Deku in an awkward position, that refusing would be harder this way.

"Of course I do, but…"

"Hm?"

Deku pursed his lips as he thought. Katsuki wanted them around his cock.

"Would it… really make you happy, Kacchan?"

"Are you stupid? Of course it would."

Deku fidgeted, nervously.

"Well, if it'll really make you happy, then...we can, um...do stuff."

Katsuki couldn't contain his smile. Deku was just so perfect for him. So obedient for his Alpha.

"Are you sure? You don't have to. I want you to do this for you, not for me."

Of course he'd play the part of a concerned adult now that Deku had agreed once. Coax him into a yes then make sure it's enthusiastic so he couldn't complain about it later. An infallible plan, really.

"It's not for you, Kacchan! I'm the one who wishes I could present already, so… it's okay. I want to do this. I promise."

Katsuki ran his fingers through Deku's hair, waiting for him to close his eyes and hum softly, a sign that he was relaxed.

"Alright then. Feel better, now?"

"Mhmm."

Katsuki moved Deku off of his lap and sat beside him, putting just enough distance between them for Deku to look to the side awkwardly as he silently wished to be closer.

"What do you want to start with, Deku? Holding hands?"

Deku protested. "Whー I'm not that tame!!"

"I'm being considerate," Katsuki said. "Since you're inexperienced, and all."

"I want to kiss!" Deku yelled, adamant. "I'm not a wimp and I'm not scared or anything."

So cute.

"'Course you're not. Okay then. You gonna kiss me or not, nerd?" Katsuki patted his lap. "I'm all ready for you, baby."

"I'm not a baby, Kacchan."

Katsuki chuckled. "Oh, I know. You said that the other time too. But you know what it means now, don't you, baby?"

Deku blushed.

"Yeah, I know what it means. It means you're a pervert," he retorted.

Nonetheless, he walked over to Katsuki and straddled his lap.

"I won't deny that," he said. "But no, that's not quite what it means."

Deku mused for a moment, before pouting.

"You want to know what it means?" Katsuki asked.

Deku didn't answer, instead leaning forward and parting his lips. Katsuki closed his eyes and let the little high schooler kiss him. His inexperience was painfully obvious. The blonde pulled away.

"Not like that. Copy me."

This time, Katsuki led, cupping Deku's face and pulling him in for a kiss. It was slow, soft, and almost romantic. Almost. Once Deku seemed to get the hang of kissing, Katsuki bit the younger boy's lip, a silent demand for him to open his mouth.

Deku complied, his eyes shut tight in embarrassment as Katsuki dipped his tongue into Deku's mouth for a taste. Deku tasted...sweet, but spicy at the same time. Like he was Katsuki's favorite food. Like he was just made for Katsuki to devour.

And devour, he would.

Deku moaned. This needy, just from a little kissing? What a virgin.

"Good boy. You're learning."

The teen covered his face with his hands.

"It's unfair to call me that, Kacchan," Deku complained.

"And you think that cute nickname is fair? Come on, little boy, don't tell me you're clueless."

"L-li-litー Kacchan!"

Katsuki smirked.

"Oh, you like that one too? I'll take note. Anyway," Katsuki gripped Deku's plump ass, kissing down his neck and lapping up his little sighs like a hungry predator.

"It means… you're mine. And you always have been. Right, baby?"

Deku shuddered.

"Oh, look at that. Your stupid little cock is hard."

“K-Kacchan…”

Katsuki laughed, the sound of it smug and condescending.

“I wonder if you can even call it that, with how small it is. I could probably jerk you off with two fingers.”

Deku fidgeted in the blonde’s lap, clearly feeling both aroused and self-conscious.

“You getting cold feet, nerd? Thought you said you weren’t a wimp. You can do a little more than this, yeah?”

The teen pouted, upset at Katsuki’s teasing. Deku pressed himself up against Katsuki, eyes widening when he felt the bulge in Katsuki’s pants. He could feel the difference in their sizes, even through his clothing. Deku, at full hardness, was really nothing compared to the blonde. Deku shifted his hips forward, tentatively, and Katsuki’s grip on his waist tightened. He sucked in a strained breath and it made Deku’s cock twitch.

Katsuki was holding back his moans, not wanting to let the nerd know about how good he was feeling just from dry-humping. The feeling of Deku’s lithe little body against him was enough to make his pants painfully tight. His mind was running wild already, thoughts of corrupting the pure little boy preoccupying him enough to where he was certain he wasn’t enjoying this moment to its fullest. He could be patient. He’d waited ten fucking years for this and wasn’t about to ruin it with his own fantasies taking over.

“C’mon, baby, give me a show. Grind yourself against me like the desperate bitch you are.”

Deku whimpered and wrapped his arms around Katsuki’s neck, looking him in the eyes.

“I-I’m not desperate!” he protested, but the boy was now grinding against him with the sort of speed that just screamed desperation, humping the adult all needy.

Katsuki bit his lip to bite back a moan.

“Fuck, you’re such a virgin.”

Deku’s breaths were now ragged, and he was evidently close to cumming with the way his movements picked up speed.

“D-Does that... turn you on, Kacchan?”

Katsuki chuckled.

“You don’t know anything about the pleasure I want to give you.”

The blonde leaned forward to kiss Deku’s jaw.

“No one’s touched you before.”

He moved his lips further down, savoring the sound of Deku’s whines.

“No one’s seen you the way I’m going to.”

Katsuki licked Deku’s neck, before biting down lightly, teasing Deku with the prospect of rougher treatment. Deku moaned, and Katsuki grabbed the boy's ass in response, forcing his hips down against his own erection and enhancing the friction between them.

“No one’s heard you like this, either. I’m going to take all your firsts, baby,” he growled.

Katsuki bit down on the boy’s neck hard, simultaneously rocking his hips up against Deku’s tiny, pathetic cock and reveling in the moment as Deku reached orgasm, shaking and moaning and sounding like something Katsuki could worship.

All Katsuki could do was laugh. Deku was fucking putty in his lap, his little All Might shorts stained.

“You’re fucking cute, you know that? It almost pisses me off.”

When Deku recovered enough to speak again, he hit Katsuki with a snarky comeback.

“If you’re pissed off about it then act like it, Kacchan.”

“You really have the gall to act bratty when you just came from dry-humping and a hickey?”

Deku looked at him with just as much determination as ever, although his eyes were lidded and heady with lust.

“You’re the one who suggested this.”

“And you’re the one who agreed,” Katsuki retorted. “Keep acting like this and you’ll be jelly even before I’ve put my cock in you.”

“Not true, ‘cause I’m gonna suck you off first.”

“You know I meant in your cunt, smartass.”

Deku gave him a lazy smile and placed his hands over Katsuki’s signaling for him to let go. Katsuki didn’t want to, in all honesty, but he complied regardless, if only to humor the boy. Deku stood up, placing his hands on Katsuki’s thighs. He leaned forward to give the blonde a quick peck on the lips, before squeezing his thighs and dragging his hands down. God it was sensual, watching Deku drop to his knees before him and work at unzipping his pants. He’d obviously fantasized about making a big show of this before, because he couldn’t just naturally be this fucking sexy as a virgin. Acting and looking like a goddamn pornstar at fifteen. Katsuki lifted his hips and let Deku drag his pants down. Deku grabbed the waistband of Katsuki’s boxers and gulped like he was afraid. He pulled down the boxers anyway, eyes widening when he was met with the sight of Katsuki’s hard, fat cock. It was already dripping precum and Deku was salivating like it was better than any of his wildest dreams. Katsuki wanted to gloat, but held his tongue. It wasn’t like he could call up Shitty Hair and brag about it. Not until Deku was marked as his, at least.

“You think you can take it, little boy?”

Deku blushed in response and furrowed his brows. He wrapped his hand around the base of Katsuki’s cock.

“Yeah, I can.”

He surely couldn’t, but the statement aroused Katsuki anyway.

Deku started stroking Katsuki’s dick, his grip much too light, but goddamn it felt so good for Katsuki to finally, finally have the object of his affections touching him. He couldn’t help but suck in a sharp breath.

“Spit on my cock and grip me tighter.”

“...What?”

“You’re already drooling, Deku. Shouldn’t be hard.”

The teen promptly shut his mouth, and Katsuki watched his face turn red for the umpteenth time. Deku made a face at him to be sure Katsuki knew he had been upset by the remark, but he obeyed anyway. He spat on Katsuki’s cock and squeezed tighter, continuing as he had before.

“Atta boy. Just...like…that. Ohh, shiiit.”

Deku dragged his tongue slowly over Katsuki’s shaft, clumsily lapping at the precum dripping down it.

“Mmm, yeah, fuck. Do that again while jerking me off.”

Katsuki looked down at the sight, and man was it fucking sexy. The blonde ran his fingers through unruly hair and held it back, wanting to get a better view of Deku’s lewd face.

“Thought you were gonna suck me off, Deku,” he teased. “You chickening out?”

The boy’s eyes flashed with annoyance and Katsuki only smirked. In response, the green-haired boy swirled his tongue around the head of Katsuki’s cock and sucked, hard, eliciting a deep groan from the elder man.

“Ohhh, yes, you’re so good.” Katsuki even chuckled at the way his own thighs jerked. God, he wanted to ruin this boy. “I always loved your defiant side, Deku. Now it’s just a fucking turn-on.”

Deku gave Katsuki a few more teasing licks around his cockhead before lifting his head up to let his hand do the job.

“So it wasn’t a turn-on before?”

Katsuki and Izuku locked eyes and for a tense millisecond, Katsuki thought he’d been found out.

“It was charming,” he replied, dodging the question.

“Hmm,” Deku mused. “I guess I’m a little disappointed.”

Disappointed? Disappointed at the notion that Katsuki hadn’t been lusting after him for years, like a normal, upstanding, good human being? That he’s not just a hero helping out a long-time friend in this situation?

“And I’m a little disappointed that you decided to stop sucking my cock,” the blonde diverted. “You can take more of me than that, can’t you?”

Deku looked up at the blonde with something akin to disappointment, but as Katsuki knew, he was never the type to back down from a challenge. He wasn’t worried about it.

“You’re a pervert, Kacchan.”

“You’re the one kneeling in front of me with cum-soaked shorts, mister.”

Deku knew he couldn’t argue, since he had suggested to do this anyway.

“Shut up. You’ll be in as bad a state as me soon enough.”

Katsuki was looking forward to it.

“Move. I’m gonna stand up so I can fuck your face easier.”

“I never said I would let you—”

The blonde laughed.

“Do I need your permission, I-zu-ku?”

Deku froze.

“Th-That’s not fair, Kacchan.”

“You don’t wanna feel my cock in the back of your throat, little boy?”

Deku shivered.

“St-stop, I—”

Katsuki stood up from his seat, appearing so much bigger. Deku was clearly intimidated, but if the wet spot growing in his pants was any indication, he was also clearly aroused at the thought. The pro hero chuckled.

“Don’t worry baby, I’ll be gentle with you...at first. Sound good?”

Deku nodded, staring only at the cock in front of him and nowhere near Katsuki’s face.

“Um...Ka-Kacchan…?”

“What is it?”

“C-Can you...um...slap it against my face?”

“Fuck.”

Deku was so fucking slutty for a virgin. God, they really were a match made in heaven. What kind of fifteen-year old boy spends his time thinking about having an adult’s cock slapping their face? Then again, Katsuki was thinking worse things about Deku at fifteen than he ever should have. And it wasn’t even limited to just thinking, either.

“When were you gonna tell me you’re a fucking cockslut, baby boy?” Katsuki asked, holding his cock and tapping it against a flushed freckled cheek. “How often have you imagined me shoving my cock in your face like this?”

Deku stuttered. “I-I don’t know...but a lot of times. I...I always think about Kacchan when I masturbate. About Kacchan being mean...and being nice...and rough...or gentle…”

Katsuki felt his stomach tighten as he whacked his cock against Deku’s soft cheek.
“Your thoughts are just full of me, huh?”

Katsuki rubbed his cockhead against the boy’s face, humming pleased at the sensation.

“Fucking slut. Do you finger yourself while thinking of me?”

Deku didn’t answer his question, but instead lowered his dirtied shorts in order to touch himself easier.

The boy opened his mouth wide, sticking his tongue out and fuck, Katsuki was not going to only play this in his mind forever. He took out his phone, pressing record.

“Look at you, Deku, touching yourself to getting your face slapped with my cock. How slutty are you?”

Deku tried to cover himself up, but he had to admit that being recorded had a certain appeal to it, if he thought about Kacchan jerking off to this later.

“I-I’m not slutty, Kacchan.”

“You’re not? But you want my cock in that pretty mouth so badly, don’t you?”

Deku looked not into the camera lens, but into Katsuki’s eyes with desperation.

“Please, Kacchan, I want you. I want your cock.”

God, Katsuki was going to remember this moment and probably fucking bust every time he watched this video in the future, knowing Deku didn’t give one flying fuck about saying shit to the camera and instead prioritized him.

“Fuck, Deku, you’re such a whore. Take it. Take my fucking cock, baby.”

Deku opened his mouth wide, and Katsuki placed the tip on Deku’s tongue.

“You want it, don’t you? Show me.”

The teen gripped the base of Katsuki’s cock, spitting and slobbering all over it before taking it into his mouth. He bobbed his head up and down and sucked with enough force to make Katsuki’s eyes roll back. Deku was always a fast learner and boy was he getting good at it.

“Mmm, shit, did you practice on toys or something? You’re taking my cock so good, baby boy.”

Deku moaned something that sounded like a muffled “mhmm” and Katsuki’s eyes softened.

“You’re so fucking good, Izuku.”

Then Deku made this face of pure bliss that had Katsuki losing control. Katsuki bucked his hips forward, pushing the tip of his cock to the back of Deku’s mouth. He made this horrible gagging sound, but didn’t push Katsuki away and that…that was too much. Katsuki fucking adored this boy. He groaned and pulled out a little, running his fingers through the boy’s bangs to see that teary-eyed, flushed appearance in full. It was beautiful. Katsuki pushed forward again, slow, crimson eyes never leaving green.

“You’re so pretty. Such a good boy, Izuku.”

He thrusted his hips as slow as he could manage, cock twitching every time Deku choked. It sounded so good.

“Shit, you squeeze me every time I call you Izuku. It’s too cute.” Katsuki forced Deku’s head down on his cock. “You feel so good, Izuku.”

Deku gripped his thighs hard, and moaned high-pitched. Katsuki felt the base of his cock throbbing as the scent of his own desire permeated the air. The blonde’s hips snapped forward and he growled through a cocky smile.

“You're really enjoying this, aren't you?”

Katsuki fucked into the boy’s mouth relentlessly, chasing his release as his knot inflated. He couldn't wait to finally fuck this kid without anyone having a say in it. Katsuki would claim him tonight and this boy would never know anything but him moving forward. Deku kept making noise, probably in protest, but Katsuki was too far gone in euphoria to stop now. He wanted to toss his phone and fuck Deku’s mouth freely, but he knew he’d be mad if he didn’t record it at least until he came.

“C’mon Deku, smile. Aren’t you happy? Caught such an important moment for you on camera. Your first blowjob and you're dripping from it.”

Deku’s eyes were rolled back, one of his hands had snaked down to jerk at that tiny cock of his again.

“God,” Katsuki laughed. “You're such a fucking slut." The adult continued to thrust in and out, gripping Deku's curls with one hand and recording on his phone with the other. "Look so good choking on my Alpha cock, baby. Mmm, fuck you’re tight.” The blonde watched Deku struggle to continue fitting him in his mouth as his knot inflated. Poor boy couldn’t even get his lips around it.

“Nnngh. I’m gonna fucking cum. Ah!” Katsuki chuckled, euphoric. “Fuck, take it, take it— Nngh!!”

Katsuki spurted cum right down Deku’s throat, feeling ecstasy when the boy swallowed around him. He mixed between groaning and laughing from the pleasure.

“Show me.”

Deku parted his lips, showing his empty mouth. Katsuki’s cum dripped down his chin, and the blonde caught it with his thumb, lifting Deku’s chin and sticking the fluid back in his open mouth, caressing his tongue with quiet reserve.

“Don’t waste,” was all he said.

Deku’s eyes were now heady with lust, and he just let saliva drip from his mouth while Katsuki rubbed his tongue, amused by how obedient Deku looked.

"Kacchan," the boy whined, looking up at the blonde with glossy eyes.

If only he knew just how much the name affected him.

"You're so good. It's unfair."

"Why, 'cause you wanna ruin me?"

That comment. How was Katsuki supposed to answer him? With the truth?

"Aren't you asking me to, Deku?"

"Maybe. I really would like to present soon."

Cheeky.

"Whatever. My turn now. Get up on the couch and open your legs for me, baby."

Deku tried to protest, again, that he wasn’t a baby, and Katsuki gave him a pointed look. The freckled boy did as he asked, discarding his shorts and hoisting himself up to the couch.

“Are you really gonna get shy now? Like we haven’t bathed together multiple times.”

Deku pouted and opened his legs, slowly. His thighs were fucking wet. His dumb little cock was hard, too. But good god, it was a sight to behold. Katsuki seeing that pretty cunt spread open, for him, for no one else. Ughh, he was gonna fucking destroy this boy. How the hell did he manage to get so wet, just from sucking Katsuki off?

Katsuki got down on his knees and just fucking stared at Izuku’s cunt for a while.
“Do you have any idea how fucking pretty you are, Deku?”

Katsuki watched the teen’s dick twitch just from his words.

“I...um...no….?”

“Well, you are, nerd. Especially...here.”

Katsuki took a hand and dragged it up the boy's thigh lightly, before rubbing circles on his inner thigh, watching his pussy twitch without being touched. What a fucking sight, this boy. Katsuki took the boy's legs and spread them further apart, then dragged a finger up his folds, feeling just how hot Deku’s pussy was. Fuck he was so wet. Katsuki couldn’t help himself anymore. He glanced upward to see Deku watching him with a flushed face, that blush deepening once the two made eye contact. Oh, what a cute reaction. He made sure to hold the boy’s gaze as he took the boy’s little cock into his mouth. Hearing Deku’s little gasp was music— it was fucking music. Katsuki sucked and moaned, able to fit the whole thing in his mouth. Deku squirmed and moaned as Katsuki teased his cock with his mouth and his hole with his fingers. How the fuck was he so mesmerizing? For a fucking virgin. He was so fucking cute and Katsuki couldn’t think of anything but how much he wanted to ruin him.

“K-Kacchan, w-wait, I feel…”

Katsuki stopped teasing the boy's cock, unable to ignore how wet his fingers were getting. He needed to taste him.

“K-Kacchan, I’m...I’m getting dizzy…”

The blonde kissed Deku’s inner thigh, up to just beside his folds and down again, taking a moment to lick the wetness on his thighs, biting and sucking at it hard enough to leave marks. Deku was gasping, desperate at this point, trying to grab at the couch and finding nothing to hold on to as he watched Kacchan beneath him, looking at him like a starved beast. It made the boy shiver with delight. He felt hot, his skin was burning, his mind was hazy and his body started itching with need.

“Kacchan,” he gasped, fervently. Deku couldn’t find words. “Kacchan,” he begged again.

Katsuki looked up at the freckled boy again, finding tears in his eyes and a heavy blush on his face, one that seemed to travel down his body. Katsuki dipped his tongue tentatively between Izuku’s folds, trying to hold himself back at the boy’s reaction. His whole body seemed to be convulsing, and all he could do was whine “Kacchan.” The blonde licked him again, tasting the slick of Deku’s pussy, which was now acting like a leaky faucet. He smelled so good, like he was— Oh my God, those were his pheromones. Fuck, Deku was presenting. And boy was it really fucking him over. Every single movement of Katsuki’s tongue had him shaking, but Katsuki couldn’t stop himself from lapping up his Omega’s delicious slick. It was fucking addicting, and his reactions were so so cute. He seemed like he was even in pain, but Katsuki wanted this to be good for them both, so he released his own pheromones to calm Izuku a bit and help him focus through the haze. He couldn’t exactly speak while tongue-fucking the boy, so instead grabbed his hand and interlocked their fingers to ground him. Deku gripped his hand tightly, then seemed to relax just a bit. He continued to drag his tongue between Deku’s folds, pushing the tip of two of his fingers into Deku’s slick cunt, which was soaking at this point. He pressed forward ever so slightly and the boy sucked his fingers in like they belonged there. Like he was meant to be filled with Katsuki. The high schooler whined and moaned as Katsuki began to finger him, astonished by how good it felt to make Deku — his omega — feel good.

Katsuki stopped his ministrations and looked up to Deku, who was resting his head back on the couch.

“You okay, baby?”

A nod.

“Feel good?”

“Mhmn…”

“Can I go harder?”

Another nod. Good, a green light.

Katsuki smiled and looked up at the boy before resuming what he had previously been doing. He started to thrust his fingers in and out of Deku, earning needy, whorish moans and groans out of him. He sounded like he was so into this, like he loved everything about it, like he was a fucking slut just *made* for Katsuki to use.

“God, Deku, you sound so good.”

“K-Kachaaann, p-please...ahh! Hah, p-...please- mmnnh!”

“Please what, nerd?”

“P-...please don’t stop…! I’m gonna cum. I’m gonna cum, please, fuck,” he whined desperately.

“Hmm, I dunno, maybe you should ask me first....Did you just tighten up? Hah! Fuckin’ whore.”

The schoolboy whined.

“Ask me, Deku.”

“Y-You’re so mean, Kacchan...I wanna cum, please…”

The blonde snickered, slowing down the thrusts of his fingers and watching the boy clench around him.

“That’s not how you ask, nerd. Do it properly, like the good boy you are.”

“Kacchan...p-please...can I cum?”

Katsuki inserted a third finger, feeling his cock leak precum as Deku’s eyes rolled back from the intrusion. It had to be illegal for one boy to be this fucking sexy.

“No.”

The teen whined, clearly frustrated. God, did Katsuki love being dominant.

“B-but…!”

Katsuki curled his fingers upward, hitting the boy’s gspot, feeling triumphant at the reaction he got. The boy was squeezing his other hand so tightly Katsuki was beginning to think it’d leave scratches.

“Beg harder. Like you mean it.”

“P-please Kacchan, please let me cum! Please, please please, I wanna cum so bad, I’ll be good, I’ll be a good whore I promise—”

Fuck.

The blonde simply couldn’t deny him any longer after hearing that, hitting the boy’s gspot and bringing his mouth back down to swallow his little cock whole. Deku groaned deep and fuck it sounded animalistic, feral, just the way an Omega should be and he was once again, convinced that Deku was made for him.

When Deku came, squirting all over Katsuki’s couch and practically soaking his chin, Katsuki was amazed.

Of course everyone had their mates, but Katsuki knew their tie was deeper than that. He was sure Deku knew it now, too. The moment Deku had released his pheromones Katsuki had felt the air change. Every fiber of his being had told him that they were meant for each other. Nothing he had done to Deku before could really be that wrong, because after all, they were soulmates, right? Their love for each other transcended everything. Even morals! Or maybe especially so.

When Deku’s breathing regained normalcy, he smiled down at Katsuki, lazily, clearly with his head still fuzzy from having such an intense orgasm. Katsuki thought he looked like a little angel, and maybe— just maybe, it made him blush a little. And get harder, thinking about corrupting someone as pure as Deku. But opposites attract, don’t they?

“Hey,” Katsuki said, standing and fixing his slacks. “Have you returned to earth now?”

Deku giggled.

“Yeah. Still feel like ‘m in the clouds though. I’m...really happy, Kacchan.”

Katsuki’s heart was doing little flips, but he played it cool.

“Why, ‘cuz you belong to me now? Told you you’d be an omega, stupid.”

“Yeah.”

Fuck. How was Izuku so cute? Katsuki felt torn by the desire to ruin and the desire to pamper and spoil the curly-haired boy.

“My god. This has got to be illegal,” Katsuki muttered.

“What, you having sex with me?” Deku retorted. “I know.”

“No, idiot, how fucking cute you are. Listen, I helped you present, okay? So we’re done now.”

Back to pretending to be an upstanding citizen who totally wasn’t constantly preoccupied by thoughts of ruining one particular underage boy.

“But I’m in heat, Kacchan…” Deku pouted his lips. “Besides, you did win the bet...I’m yours now.”

Katsuki faked a chuckle.

“What, so you expect me to breed you?”

“Yeah. I want you to.”

Fuck, he was so fucking eager, Katsuki couldn’t take it.

“...Deku, do you really want that?”

Katsuki sounded so concerned he nearly surprised himself. Deku stood, and stared at the blonde with the same determined look that always set Katsuki ablaze with desire.

“Just take me to your bedroom, Kacchan.”

Katsuki’s dick twitched in his pants, thinking about how finally, finally Deku was going to be his. All his.

For a moment, they stared at one another. It was an exchange that spoke volumes, despite being completely wordless. As if their lives had been building up to this. Though, Katsuki had certainly orchestrated this from the moment he became an Alpha. His gaze bore through the little boy, but Izuku didn’t waver. He was sure about this.

Of course he was sure. Katsuki had made it so.

The blonde let a little smirk settle on his lips. He unbuttoned the top of his shirt, revealing the black tank that remained a staple in his closet after all this time.

“Come and get me, nerd.”

Deku had that glint in his eyes that made Katsuki go feral. He walked over to Katsuki, slowly, never breaking eye-contact, knowing damn well that Katsuki wanted — no needed — him now. The high schooler came up to him, gripped his shirt, and pulled him down so their faces were close. Katsuki had a realization that nobody else in the world could get away with doing this to him.

“You better fuck me right, Kacchan.”

If Katsuki had been some lowlife normie, he would’ve fucking creamed his pants like a loser. But he would do exactly as Deku asked. He was almost pissed at how hard the boy’s demand made him.

“Oh, you won’t be fucking walking tomorrow, Loser.”

Deku just grinned. Katsuki wanted to wipe that smug look off his face, so he kissed him, grabbing his waist and pulling him close. When the boy kissed back, he was surprised by how good it felt. What a fast learner, Katsuki would have to praise him for that. The blonde hastily pulled off Deku’s shirt, eager to see him naked. When the shirt was discarded, he lifted the boy a little more, then felt Deku wrap his dainty little legs around his waist. Fuck, he was so light.

“Fuck, your slick is gonna ruin my pants.”

“You’re the idiot who put them back on.”

Katsuki flipped them and pressed him against the wall as they kissed, turned on by Izuku so desperately trying to unbutton his shirt despite being clearly overwhelmed. Katsuki chuckled into the kiss.

“Wait wait, let me open the door.”

Katsuki put him down and grabbed the doorknob. As soon as it was open, Deku was on him again, this time trying to get off Katsuki’s slacks.

“That desperate to have my cock in you, baby?” Katsuki laughed. He grabbed the boy's hands to stop him, then pulled him in for another kiss. Izuku squealed a little when he was lifted up and tossed onto the bed.

“Just watch.”

Katsuki unbuttoned his shirt swiftly, eyes never leaving the sight of Deku’s naked body.

“I’m gonna fucking ruin you, nerd.”

He discarded his black tank to the ground.

“Bet a pervert like you would probably touch yourself to the scent of my shirt, hm?”

The idiot couldn’t even respond, just watching Katsuki’s deft hands as he ran them over his bare abdomen and down to the buckle of his pants.

“I don’t know why you’re so speechless watching me when you just sucked me off a little while ago, baby boy. You did so good, too,” he said, undoing the zipper and pulling down his slacks. His boxers were clearly wet with precum and the sight of it made Deku whimper.

“Look at you, all whiny. You want me so much, don’t you, Nerd?”

“I want you, Kacchan,” the boy whined.

Katsuki groaned, dick twitching at how fucking pathetic Izuku sounded.

“Yeah?”

“Yeah. A lot.”

“You’re so fucking cute.”

Katsuki discarded his last piece of clothing, and crawled into his bed above the high schooler.

“See what you did to me?”

He watched Izuku’s eyes settle on his cock. God, he loved Deku looking at him like this. He opened the boy’s legs, marvelling at the sight of his hard cock and soaked little pussy. Deku looked so tiny beneath him, he couldn’t help but imagine the little bulge his belly would show.

“This is all your fault, baby. I can’t stop now, can I?”

Deku shook his head no, and Katsuki decided to settle his cock on top of Deku’s.

“You’re so fucking small compared to me, it’s sad.”

Deku’s hips jerked up and he rubbed himself against Katsuki desperately. The blonde pinned his hips down.

“Did I say you could do that?”

“N-No…”

“Then don’t. Get on your knees for me, baby.”

Deku whined, but sat up facing Katsuki anyway.

“No, no, all fours.”

Deku did as he asked, and once again Katsuki was so pleased by his obedience. Such a good boy.

“You look so good like this, baby. Pretty little cunt all wet and dripping for me.”

Katsuki slid his cock against the boy’s cunt, moaning at how good it felt. Deku whined at the stimulation, more slick pooling out of him. Fuck he smelled so good, it was hard for him to fight back his Alpha instincts. He wanted to tease him just a little more.

“Kacchan I need you, I need your cock, Alpha, please–”

As always, Deku was making this hard for him. He couldn’t say no, not with his Omega begging so sweetly. He placed the tip of his cock at Deku’s entrance, and looking at how fucking big he was compared to the boy’s virgin cunt made him leak. Deku was going to take all of him.

He pressed the tip inside, and Deku started whining in protest.

“K-Kacchan, wait, i-it’s so big, it won’t–”

“I’ll make it fit, Nerd.”

The blonde forced himself inside, getting harder upon hearing Deku’s little scream of pleasure. Sounded so fucking good, moaning for him. After protesting too. Now he sounded like a fucking whore, pleading and whimpering all desperately like a cock-drunk bitch.

"Fuuuck, Deku, you're tight. And your slick, holy shit. Mmm, such a good omega, squeezing my cock like this. It's what you're made for."

"K-Kacchan, please… 'm so horny, I need you to move. Come on."

"What, I can't bask in the glory of being in such a perfect, slutty pussy before I wreck it?"

"Kacchaaan," Deku whined. "Please. Please fuck me already, I've wanted this for years, pleaseee."

"Fuckin whore. Don't worry though, baby boy, I'll be sure to ruin you for anyone else."

"There was never anyone else."

And that's what makes Katsuki decide to thrust balls deep in one go.

"That's fucking right, Deku. This is my pussy. Not yours."

Slowly, Katsuki pulled out, Deku gifting his ears with a high pitched whine.

"And I'm gonna use it whenever I please."

Again, he pulled out, feeling Deku's walls constrict around him.

"Don't you see? It's all you're good for, quirkless Omega like you."

Deku whined again, this time louder.

"All you're good for is being used like a toy, baby. You understand?"

Deku moaned. Katsuki sank himself back inside the boy’s tight heat.

"Fuck, Kacchan, it feels so good…!"

"I asked you a fucking question, nerd. You obviously still know how to talk, so you better fucking answer me, little boy," Katsuki growled. He wasn’t planning on making things easy for Deku, pulling out once more, as slowly as he could possibly manage. The groan Deku let out in response was enough to send a shiver of pleasure down Katsuki’s entire body.

"Ohh...fuck… yes, Kacchan — ah! I...I understand."

"You understand what?"

"That…” Deku gasped, breath quivering like he was in far more pleasure than he ever imagined he could experience. “...all I'm good for is being used like a toy."

"Whose toy?"

"Yours, Kacchan! Ah! Please, I can't take it anymore, please go faster."

"Oh, the little slut wants more of my cock?"

Deku shook beneath him, biting his lip to hold back a moan. It was obvious from the way Deku’s pussy tightened that the word “slut” was doing things to him, but of course Freckles didn’t want to admit it.

"Fuck, you're so tight, baby."

"Yes, Daddy, please…!"

Now it was Katsuki's turn to groan. Fuck, did that title do things to him.

"Say that again."

The blonde’s voice came out more constricted than he’d wanted it to, but God, it was hard to keep composure. He’s wanted this boy for so long, so long.

"Daddy...Daddy…!" Deku moaned.

"Shit, you're so good, Deku."

"I'm not good! Sh-shut up!"

Katsuki chuckled. He couldn’t even speak properly right now, let alone talk back. Deku was definitely a good boy. He always has been.

"Yes you are, baby. You're so good for me.” Katsuki pushed himself inside once more, hissing from the pleasure. “You've always listened to me.” He pulled out. “Like a good Omega.” In. “You know that, right?” And out again, nipping at the skin on Deku’s shoulder before bringing his mouth up to the boy’s ear. “You've always belonged to me."

"Go faster, Kacchan!" Deku whined. He was trying to sound insistent, but there was so little power in his words.

"You think you can make demands with me, little boy?"

Deku moaned, but stayed defiant.

"Y-Yes, I can. You're my Alpha, Kacchan— Mn! J-Just as much as I'm your Omega."

As shaky as his voice might've been, there wasn't an ounce of doubt in Deku's words and it turned Katsuki the fuck on.

"Fuck. You think you own me? You're my fucking property, you little brat."

The term brat seemed to piss Deku off just enough for him to find his voice.

"Go. faster. And yeah, Kacchan, I do. You're the one who taught me how to touch myself. I'm not little anymore. I know what you were doing. You're so obsessed with me that you taught me about masturbation at ten. I remember the way you touched me. You wanted me so badly that you didn't and don't care how old I am. So yeah, I think it's fucking safe to say I own you."

Jesus fucking Christ. Deku knew. He fucking knew.

"I've gotten off to the thought of you corrupting me for years, Kacchan. You fucking did it. And it turns me on. You've waited so long for this. Just to fuck my pussy. You're nasty, Kacchan, because of me."

Katsuki gulped. Deku was just as depraved as he was.

"And I love it. So go faster."

Ohhh, fuck.

"You sly, little boy."

Katsuki pulled out, slowly.

"Maybe you're right about me being obsessed. But I'm the one who owns you, baby."

The blonde thrusted into the little teen, groaning at the sensation, marvelling over how much of his hands fit around this tiny waist, at how fucking well this boy was taking his fat cock.

"I own you, Deku. You're mine now. For the rest of your life."

Katsuki felt the boy's cunt tighten.

"C'mon baby boy, say it. Tell me I own you, or I'll tease you all night."

"You...you own me, Kacchan. I'm yours."

"Fuck yeah, you are," Katsuki growled, a triumphant smirk on his lips.

Katsuki began fucking the boy's cunt faster and harder. It felt so, sooo unbelievably good to be inside Deku, to be in his mate, his lover, his little boy.

The blonde devoured him — his little whimpers, his moans— God, those fucking moans— he took them into his being and drank them up like it was ambrosia of the gods. And it might as well have been.

"Pl-Please, Kacchan, fuck—"

"Call me 'Daddy', princess."

The teen squeezed his cock at the petname, making the adult feel both empowered and soft at the same time. So cute of him to be into being called that.

"Hhhhh, fuck, Daddy!"

"What, baby boy?"

Deku just continued to moan 'Daddy' over and over like a pathetic whore. It only made Katsuki hotter, thinking about how fucking mindless he'd become by having Kacchan fuck his tiny little pussy.

"Daddy...ahh, Daddy…!"

"Can you use your words for me, Izuku?"

"Hhhnnn, 's...so good, Alpha…!"

"What's so good?"

"Mnh! Y-your cock, Kacchan…! F-feels so good having it in me! Ohh, fuck, please…"

Katsuki's eyes rolled back as he fucked into the teen harder, thinking about how wrong it was for him to be fucking Deku when he was still so young, knowing damn well no one could say anything to him now. Deku was all his. His property. Fuck, he'd get this little boycunt to himself every day! Mmmn god, it was everything he'd ever wanted. And to think that little innocent Deku was just as disgusting as he was. They really were soulmates, weren't they?

"You like getting adult cock in your little pussy, Deku? You fucking slut."

"Nnn…! D-Don't say that, Kacchan…!"

"Why not? You were so bold about it earlier. So bold telling me you got off to being groomed by me. You like being manipulated?"

Deku moaned again, sounding fucking depraved. It was delicious.

"You're fucked up, Deku. This was your plan all along, wasn't it? To get me to induce your heat so I'd have no choice but to make you mine."

Katsuki drove his hips forward, deeper into the little boy's cunt. Deku only seemed capable of moaning.

"Answer me, little boy."

"Nnh...f-fine, yes...I...I wanted Kacchan to be the one...wa-wanted to make you fuck me in my heat so you...so you would have to claim me– ahh!– or risk your whole career."

Between those moans, Katsuki heard a chuckle.

"C-cuz you can't fuck a kid a-and not claim them as your mate... it'd make you a criminal."

Katsuki gripped the boy's waist harder and leaned forward to snarl in his ear.

"I've been a criminal for you for a looong time, Izuku."

Izuku then cried out, his walls constricting around Katsuki so tightly it made the man see stars. No hole he'd fucked had ever made him feel like this. He'd never been so fucking hard, never been more of an Alpha than he was in this moment, watching Izuku shake from orgasm around his cock.

Izuku was his.

"Izuku."

"Mm...?"

The boy was definitely subdued at this point, his orgasm must've taken all the brattiness out of him.

"Izuku," Katsuki cooed, fucking him nice and slow. "You're a good boy, right?"

The boy shuddered beneath him.

"Y-Yeah, 'm a good boy."

"That's right, baby. Is it okay if I flip you into your back? Your legs must be tired, right?"

Izuku nodded. Katsuki felt his heart swell. Fucking stupid nerd, being so damn cute. He wanted to watch him cum this time, to see the look on his face when Katsuki pumped him full of his cum.

Katsuki pulled out and the boy lazily rolled over onto his back. He was so pliant at this point he might as well be putty for him.

“You wanna be good for me, Izuku?”

“Mhmm.”

Katsuki spread his legs apart, crawling on top of the curly haired boy. He looked so small underneath him, and fuck if it didn’t make Katsuki harder.

“You make me feel so good, Izuku.”

The blonde entered him again, hissing at how tight Izuku still was. The younger boy gasped, his eyes rolling back at the sensation of feeling good again.

“Alpha, please...please breed me. I want you.”

“Yeah? Say it again for me, Princess.”

Izuku whined.

“Please, Kacchan, I want your babies.”

Katsuki drove his hips forward. Fuck, he could see himself through Izuku’s bulging belly at this angle. He was so fucking tiny. So small. And the thought only made Katsuki fuck into him harder. Fuck, taking advantage of a little boy felt sooo good.

“Good Omega. That’s what you’re made for, right?” Katsuki cooed in his ear.

“Mhmm, ‘m made for you, Kacchan.”

“Fuck. Why are you so cute?”

Katsuki took one look at his face and realized he wouldn’t be getting an answer anytime soon, if at all. Not with the idiot’s eyes glazed over like that. Looked fuckin’ ethereal overwhelmed with pleasure like this.

“Alpha...alpha..!”

Every stupid breathy cry of “Alpha” brought Katsuki closer and closer to release.

“You want my knot?”

“Yes, p-please, please, I want you so bad. Please fill me up, Kacchan, I need it...”

What kind of Alpha would Katsuki be to deny such a polite request?

“You’re mine now, Izuku,” the Pro Hero growled. “Mine.” And I’m gonna do whatever I want to you, he thought. But the boy didn't need to know that.

Katsuki fucked into him ruthlessly, no longer able to keep his Alpha at bay. Izuku could barely keep his eyes open from how lost he was in pleasure. The blonde remembered briefly how inappropriate it was for the boy to be making such a face at his age, and for Katsuki no less. Fuck, it made his knot swell, thinking about how wrong it was to breed such a young Omega.

"I'm cumming, Kacchan, 'm gonna cum oh fuck oh fuck–"

Katsuki couldn’t take his eyes off of Izuku. He looked so fucking pretty, beneath him, taking his cock and fucking crying on it.

“Fuck, you’re so-- Nngh, I’m gonna breed you, baby.” Another cute little scream escaped the boy’s lips. “Say you want it, say you want my cum.”

“K-Kacchan, I wa-want it, please, I want your cum, please Kacchan, please…!”

“Fuck, fuckfuck, Izuku, you’re so fucking good. You’re gonna take it all, won’t you? God, fuck, I’m cumming, oh shit-- Hahh, fuuck!”

Katsuki forced his knot into the boy, elated by the loud scream that came from his Omega as he was stretched open.

“Mmmnn, fuuuck…!” Katsuki groaned, pouring his cum into Izuku’s cunt, watching the boy convulse around him, his eyes rolled back as he moaned like a whore. It was a sight Katsuki would burn into his mind. How could he not, when their first time together was this special?

Katsuki realized he was still filling the boy with cum, his cute little stomach being so full made Katsuki even happier.

Izuku’s eyes regained focus and they settled on Katsuki. He had a dreamy smile on his face.

“Hehe...am I gonna have Kacchan’s babies now?”

How the hell did he manage to look so fucking serene when he just got bred by a grown man? He looked like he couldn’t be any happier. And fuck, if it wasn’t doing things to Katsuki.

“Yes, you are, Izuku.” The blonde leaned forward and gave the boy a soft slow kiss. He lazily returned it, giggling like a fucking idiot. “But you’re still my baby, okay?”

“Mhmm!”

He was right. Izuku did own him. But the Alpha wasn’t going to admit it. He couldn’t give Izuku the power of knowing that.

//

The first thought that twenty-two year old Bakugou Katsuki had the next morning, finding his little Omega tucked into him, breathing soft and peaceful, was that he needed protection. And Katsuki could be the only one to provide it. After all this time, Deku was still so fragile, tiny, and delicate.

“I won’t let anyone hurt you, Izuku.”

The blonde pressed a kiss to his forehead.

I won't let anyone touch you, either.

Some things would never change.
