I'm a bit overwhelmed by the sudden attention for a certain tweet I sent out. But here is the thread about Bakugo being a little obsessed with virgin Deku.
See this tweet: https://twitter.com/Dana_Eliza/status/1169870500975132672

It had been quite a surprise when those enticing words reached his ears.

Nothing could’ve prepared him for this. Izuku was still a virgin. Of course he was. Of course the idiot hadn’t managed to score a girl, or a guy for that matter, and hadn’t had sex yet. Almost everyone in their class had. They were third years for fuck’s sake.

Half of their class had already gotten into relationships or some shit, fucking almost every night. It was a good excuse, Katsuki had to give them that.

But Izuku… hadn’t gotten laid once. The girls had pulled the information out of him, giggling when he admitted that he

hadn’t slept with anyone, yet. Katsuki could see some girls’ eyes hazing over, interested in the idea of being Izuku’s first.

It all paled in comparison to what it did to Katsuki though.

Katsuki had been dragged out of his room by the idiots, to hang out or some shit, and was

forced to watch a movie in the common room. The same room where the girls decided to have a very intimate conversation with one another. Many of the boys had been listening in, hoping they’d catch some information on how to please a girl. All had stopped eavesdropping as soon as

the girls had asked Izuku to join.

Albeit reluctantly, Izuku had sat down, blushing profusely as the whole group of girls stared at him. This was the moment Katsuki’s interest was peeked. They pried and pried, questions becoming more risqué with every passing minute.

Izuku definitely didn’t answer all of them, too embarrassed to share that kind of information with them. But there was enough Katsuki caught. The most important thing, coming at the very end.

Virgin.

Katsuki had gotten to know Izuku better through their high school years. Had gotten a little closer. But they definitely weren’t that close, and Katsuki never let the word friend leave his tongue when talking about the nerd. They didn’t share their inner most secrets.

Definitely not something like sexuality. And Katsuki had never really thought of Izuku in a sexual setting before either. He mostly just fucked some girls here and there whenever he felt like it. Which didn’t happen too often. Guys had never really done it for him.

Too much of a hassle. Most guys he knew would not want to bottom, and Katsuki was not interested in being on the receiving end.

But now there was Izuku. Zero experience. Zero understanding on how sex worked. Zero knowledge on how to please a woman, or man.

Katsuki could teach him, though. Could show him exactly how it was done. Because he knew. Knew how to bend a girl to reach her best parts, and fuck her brains out. And Izuku would look so pretty folded in half, cock stuffed in his ass, moaning as if his life depended on it.

Katsuki could definitely teach Izuku how to take a dick.

Their eyes met from across the room, right after Izuku had spilled his secret. The blush on his cheeks only deepened, spreading all the way down to his neck. Katsuki licked his lips at the thought of finding how low

the redness really went. Would it reach all the way down to the nerd’s perky little nipples, or would Katsuki have to put some effort into getting them flushed?

Green eyes widened at the sight of Katsuki’s smirk growing. Izuku knew Katsuki had heard. Knew this was not going to

be the last he heard of it. Prepared himself mentally for the vigorous teasing he’d have to endure after this.

But oh, how wrong he was. All Katsuki could now think of, was how he was going to take him. Take his virginity. Be his first. Make sure Izuku would have an imprint of

his cock all the way up his ass. Ruin him for anyone else who dares to think of fucking him. Katsuki would guarantee himself that Izuku would come begging for more. Would seek Katsuki out and ask for his tight little pussy to be fucked again and again.

Izuku better be grateful that Katsuki was going to show him the time of his life.

…

It wasn’t until later in the evening when Katsuki actually managed to seek out Izuku. The group of idiots had kept him from leaving the movie early, even if Izuku had long gone to his room. Possibly too embarrassed about Katsuki knowing his dirty little secret.

The little secret that made Katsuki’s pants tighten at the sheer thought of it.

Well passed everyone’s bedtime, the movie finally ended. Finally Katsuki could leave the ones that were keeping him from his goal. Sleep was unimportant right now. Even if they had class tomorrow.

Even if Katsuki preferred waking up early. His mind was set. He could not delay this need to have Izuku. Not when he knew so many others would be chasing after the nerd as well. The girls were the only others that knew now, but once Mina starts blabbing, then everyone would know.

Meaning everyone would know Izuku’s ass would be the tightest out of all of them. Be the most sensitive. Be the most perceptible. Would probably even be the horniest of them all, because he never got laid before.

And Katsuki would make sure that he was the one who would have a taste of that eagerness.

Katsuki knocked on Izuku’s door, thumping it roughly, because stupid Deku better still be awake. It took some time, and a lot of knocking, before he finally heard movements behind the closed door. He might’ve woken up others whom Izuku shared the hallway with, but Katsuki didn’t

give a fuck. They better all know Katsuki was here first. Izuku better scream so loud, all of 3A would hear that Katsuki got to take Izuku’s virginity. All of them would know they would be too late.

“Kacchan?”

His voice was raspy with sleep, Izuku rubbing at his eyes as he glanced up at the other.

It made Katsuki feel grand that he was still taller than Izuku. Still broader build than Izuku. That he was simply still more than him. Could overtake him just by pressing down on the nerd.

At least in his mind Katsuki could. Could devour him. Claim him. Take him.

His mouth watered at the sheer thought of it.

“What are you doing here? It’s really late.”

Izuku’s voice got a little higher pitched at the end. Katsuki revelled in the sound, imaging what it would be

like once he got his cock up Izuku’s ass. Would it be even higher? Would he moan so prettily, Katsuki would want it as his future ringtone?

“I wanted to talk a little,” Katsuki replied, glancing around the sleepy form of Izuku into the other’s room.

All Might theme still very much there. “Talk about what I heard earlier this evening. It was really fucking interesting.”

That familiar blush spread all over Izuku’s face again. He quickly glanced down the hallway to make sure no one was listening in.

“Why do you want to talk about that now, Kacchan?” Izuku hissed, but didn’t step away. Didn’t close the door in his face. Mostly Izuku looked scared. Like he did when Katsuki still bullied him. As if Katsuki was going to pick up where he left off all those years ago.

“Because I’m fucking curious, that’s why, Deku,” Katsuki returned, smirk growing as he saw the last bit of defiance ebb away.

Katsuki had him now. He would make use of Izuku’s fear to get inside. Because Izuku would not want others to find out about this. At least not this way.

It made it easy for Katsuki to push open the door, and move passed Izuku. Get into the All Might themed bedroom, and have himself shut in with the little virgin boy.

The door closed with a quiet thud behind Katsuki, Izuku looking rather hesitant to follow after Katsuki.

He tugged at his sleeping shirt, it far too big for his body. Even if Izuku had bulked up a lot, his posture remained a little frail. Just the way Katsuki liked it. Under his t-shirt he wore a pair of loose-fitting boxer shorts, his junk probably dangling between his legs.

“So you never fucked anyone, huh Deku?”

Green eyes narrowed suspiciously. “No, I haven’t.”

His tone was cold and stern, ready to take on any comment Katsuki was about to throw his way. But Katsuki didn’t care about that. Didn’t give a shit about the fact that it was somewhat embarrassing to not have done anything, with anyone. He knew of a few guys in their class who

would find it unbelievable. Would tease him relentlessly. But not Katsuki. Now that he had the confirmation that Izuku was indeed a virgin, he couldn’t stop the shiver from running down his spine.

“And why is that? Something wrong with your dick?”

“Of course not!” Izuku retorted, looking utterly insulted at the comment. “I just haven’t really focused on having sex… It doesn’t seem very important right now.”

Not important… God, that was just so enticing to hear. Another challenge laid out so perfectly for Katsuki.

He would make it important. Would make it the first thing that comes to mind whenever Izuku wakes up. And be the last thing he thinks of when he goes to bed.

“Really? I still think there is something wrong with your dick. Why don’t you proof to me that it works, Deku?”

“What? No…”

But Katsuki wouldn’t take no for an answer. He was going to see Izuku’s dick tonight, even if it was the last thing he’d do.

Moving back to where Izuku was still standing, awkwardly standing by the entrance to his room, Katsuki honed in on him.

Towered over him as he cornered Izuku against his closet door. Captured him so deliciously, ready to be taken advantage of. Izuku placed a hand on Katsuki’s shoulder, fingers tightening in the fabric of his shirt, readying is quirk so that he could push the other off.

But he wasn’t yet. Waited on Katsuki’s next move. And Katsuki didn’t mind a bit of a struggle. As long as he came out on top in the end, and he was planning on topping tonight.

“Come on, Deku. Show me your little prick. Give me a little show, and convince me that it’s not broken. Can’t you get hard or something? Is it too fucking small to pleasure anybody? Is that why no one’s ever touched it? Is that why you haven’t let anyone near your pretty dick?

"Haven’t let anyone suck on it?”

His own words were making him delirious, his main focus now on the fact that no one ever touched Izuku before. Never had hands slide over his dick, stroke him to completion. Suck on it like a popsicle.

“Fuck,” Katsuki shivered, nipping at Izuku’s cheek.

“Kacchan, what are you…?”

Green eyes studied Katsuki’s heated expression first, and then slid down to look at his very obvious tented sweatpants, his erection pointing straight towards Izuku’s crotch.

It finally started to dawn on Izuku then. Understanding exactly what it was Katsuki came to do here. What he was implying as he hooked his thumbs under the waistband of Izuku’s boxer shorts. Once more his fingers tightened in the fabric of Katsuki’s t-shirt.

“Come on, Deku. Why haven’t you fucked anyone yet?”

“Maybe because no one has propositioned me right, yet.”

Oh, that was something Katsuki liked to hear.

“So Deku’s a little hard to get?”

Izuku shuddered as he felt Katsuki’s warm breath ghost over the skin of his neck, his lips so close, they were almost touching. His free hand moved towards Katsuki’s hip, fisting the fabric of Katsuki’s shirt there as well.

Hand shaking, Izuku seemed to contemplate if he should be pushing Katsuki away, or keep him right there in front of him. Hearing Katsuki’s tone, that aggravating, yet alluring tone. Even if Katsuki was insulting him, Izuku could read between the lines. Knew what Katsuki meant

with those taunts.

Katsuki wanted him, badly.

“A first time should be done with the right person.”

Katsuki watched Izuku’s Adam’s apple bob up and down as he swallowed. Finding it tantalizing as it kept on moving, Izuku clearly not in the right state of mind anymore either.

“And who might the right person be, Deku?” Katsuki purred, mouthing at Izuku’s ear. His thumbs were still stick under the waistband of Izuku’s boxer shorts, slowly easing it off his hips, inching it down gradually, but not too noticeable. “Someone who can treat you right?

"Someone who treats you to some fucking dinner first, and then shows you a good time?”

Quickly Izuku grasped Katsuki’s arm, preventing him from moving his boxers further down for a mere second. But Katsuki didn’t pause for long. Tested the waters, and then kept moving

the garment down, the elastic stretching over the round of Izuku’s ass.

“No,” Izuku breathed out. “Someone who I can trust.”

Katsuki’s hands stilled at that, pulling back a little to meet Izuku’s gaze. That was a comment he hadn’t expected.

Girls usually complained about how Katsuki never really took care of them. Just had sex, and then left. Buying dinner didn’t really seem worth it. And they all came willingly, so what was their problem. They all just wanted to be wooed.

Not Izuku though. Izuku just wanted someone who he could trust.

“And who can you trust, Deku?”

Izuku’s initial reply was a shrug of the shoulders, eyes shifting away from Katsuki’s face. The mood was changing a little, not turning in Katsuki’s favour. This was supposed to be just a good fuck, not something meaningful. He didn’t need the sappiness. Didn’t want to hear

how special it needed to be. Izuku better not start talking about some high and mighty prince that could sweep him off his feet. Better not talk about someone who could do this better. Could make Izuku feel worth of something more.

And then something else fell from his lips.

“You,” Izuku spoke resolutely. “Even if you won’t ask me nicely, I’m certain you’ll make sure I will enjoy my first time. You won’t just take what you need from me and go.”

Stupidly Katsuki blinked down at Izuku, letting the words sink in. And then a feral grin broke out on his lips.

“Yeah, I’ll fuck you good, won’t I Deku. I’ll make you scream on my cock. You’ll never want anything else, but me. And I will fuck you tonight.”

“Do I have a say in that?”

“Nah,” Katsuki quickly interjected, grin faltering as he thought of delaying their moment together to do it later on in the week. “Nah, we’re fucking doing this tonight. Tomorrow everyone will fucking know that you’re still a virgin, and they all will

want a piece of your tight little ass. I ain’t fucking sharing. I ain’t giving fucking Icyhot, or Glasses, or fucking Round face a chance. I’m gonna be your first, and because you’ll never want anything else after that, I’ll be your fucking last.”

A deep groan came from somewhere deep inside Izuku’s throat, his body trembling in Katsuki’s hold as he let the words sink in. Let the proposition seep into his skin. There wasn’t much of a choice, if he had to believe Katsuki’s words, and at this point he didn’t really want one.

If Izuku hadn’t wanted this, he would’ve kicked Katsuki out of his room. But with those boxer shorts still sliding down, now slipping under his ass, dick almost freed from its confines, Izuku just wanted this to continue.

“Okay,” Izuku hummed. “What is it that you want to do?”

Finally Katsuki pulled down the boxers low enough for Izuku’s erection to spring free, lifting up the hem of his sleeping shirt, peeking out right from under the fabric.

“Everything you haven’t done yet.”

“I’ve only ever jerked of, Kacchan. So there is a lot that I still need to do.”

Smugly Katsuki glanced down, seeing Izuku’s dick twitch slightly under the dimmed light of the nerd’s room. He felt good, really good. Had permission to do whatever he wanted at this point.

Could fuck Izuku’s ass raw tonight, as long as the nerd enjoyed it, and Katsuki would make sure Izuku enjoyed it. Would have him see starts. His body will be completely spend, unable to move at all tomorrow. Fucked so well, he would have to call in sick.

“Then we have no time to waste, Deku. Time to get fucking to it.”

At one fell swoop Katsuki pulled off Izuku’s shirt, and threw it to the ground. Izuku had complied by lifting his arms, his green eyes staring at Katsuki, waiting what was to come.

Waiting on Katsuki to take the lead and claim Izuku’s first time as his.

Red eyes peered down at Izuku’s dick. See it curve slightly upwards, the head flushed a deep red, the base a nice thickness. He wasn’t small, not at all. Not too big either. Average. A nice dick.

The little birth mark near the tip made Katsuki salivate. Never had he wanted to suck dick in his life, but now seeing Izuku’s pretty little prick, he needed it.

Instead he wrapped his hand around his length, and slowly started stroking it. The buck of Izuku’s hips said

the other was enjoying these first touches already.

“No kiss, Kacchan?” Izuku murmured softly, trying to keep his voice steady. He really was a fucking virgin.

“You gonna tell me you’ve never been fucking kissed before, shitty nerd?”

“Will you be mad if I told you I did have my first kiss already, and that I just want to kiss Kacchan?”

For a moment Katsuki’s heart flared at the idea of someone else kissing Izuku. How dare they be first. Until he dug deep, remembering everything he’s ever done with Izuku.

How long they’ve known each other already.

“Fucking whatever. I took your first kiss when we were fucking three.”

“That means I have Kacchan’s first kiss as well.”

That sweet smile staining Izuku’s lips as he let out little puffs of air, trying to not make too much sound as Katsuki kept stroking him, did wonders to Katsuki’s own erection. Fuck, did he want his dick stuffed between those rosy plump lips. But that was for another time.

Another first he could take from Izuku. Oh, so many firsts he would have.

Katsuki swiped his thumb over the head of Izuku’s cock, smearing out the drop of precum that had gathered at the tip. Izuku bit his lip at that, a needy expression overtaking his features.

And that was when Katsuki finally gave in. Dipping down and pulling that lip from right between sharp teeth with a harsh press of his mouth.

Their lips mushed together, a soft whine escaping Izuku as Katsuki pushed his tongue between teeth.

Prying them apart to claim his first taste. This was a lot different from when they were toddlers. Nothing like that awkward hardly there press of thin lips against each other. This was messy, and rough, with a touch of needy around the edges.

That became even more apparent when Izuku got bold. Placed his own hands at the waistband of Katsuki’s sweatpants, and tugged them just below Katsuki’s balls. Freeing his erection in the process.

“Getting fucking eager, Deku?” Katsuki teased, his words broken once Izuku wrapped his scarred fingers around his length, and gave it a few clumsy strokes.

“You’re one to talk, Kacchan.”

Tentatively Izuku kept moving his hand up and down, squeezing Katsuki’s dick at the base a little harder. His eyes were still hazy, but he seemed uncertain of what he was doing. As if he had never stroked a cock before. But he had just admitted that he had,

so this was just some shy bullshit.

“Come on, Deku. Jerk it a little harder. You know what you fucking like, don’t cha?”

Izuku scrunched up his nose, eyes narrowing, and jaw set tightly as a look of determination took over. His handed started moving faster, rougher,

thumb teasing at the ridge by the head of his cock, before swiping the pearl of precum away. That was what Katsuki was talking about. Jerk someone off the way you want to be jerked off.

“Like that, Kacchan?” Izuku huffed, tone more mocking than Katsuki appreciated.

Fisting Izuku’s green curls in his hand, Katsuki pulled Izuku’s head back against his closet door. “Doing fucking great, Deku. But you know what would be even better? If you get on the bed over there and let me get on top of you.”

Izuku’s stroking faltered at Katsuki’s words, a wary look taking over his features again. This was still a big step he was about to make, and even if he had already consented, it became a lot realer now. “And what are we going to do there, Kacchan?” he asked softly.

“I will touch you anywhere you haven’t been touched yet,” Katsuki growled, letting his tongue slide over Izuku’s exposed neck. The hand not buried in Izuku’s hair was still slowly stroking his dick, making sure the nerd would not go soft him.

“I’ll start at your tits, because who could ignore those perky little nipples of yours?” he whispered into Izuku’s ear, his voice still holding a bit of a bite to it. Nice enough for Izuku to shiver at the way Katsuki spoke.

“And then I’ll slide all the way down, suck on your cock, lick your balls, and ravage your pussy until you beg me to stick my dick inside you.”

“Fuck,” Izuku sighed. “Okay, yeah, fuck.”

His hand disappeared from Katsuki’s length, instead moving to the waistband of his own boxer shorts that were still tugged midway his thighs. Quickly Izuku pulled them off and kicked them to the side, standing in front of Katsuki, stark naked.

So many scars littered his body, stretching over his arms, and thighs, cuts once deep in his back and chest. Izuku’s body was flawed, imperfect, but with the added freckles littered over his shoulders and back, it had something enticing.

Scarred fingers then moved back to Katsuki’s body, reaching for the hem of his t-shirt, and then he hesitated. “You too,” Izuku explained, before pulling back, letting Katsuki do it on his own.

“Fucking fine, Deku. Me too,” Katsuki replied. “Then you get on the fucking bed.”

As Izuku walked backwards, eyes glued to Katsuki’s form, the other started undressing. With a smirk on his lips he tugged his shirt over his head first, throwing it over his shoulder. The next to come off were his sweatpants, accompanied by his boxers and socks,

left on the floor in a puddle. Green eyes had kept on staring, watching as Katsuki undressed, taking in every movement in sheer awe.

“Like what you see, Deku?” Katsuki teased, grin only growing wider as he saw the other hesitate again. Swallow the words of compliment.

Because Deku didn’t dare admit that he found Katsuki attractive. Not as long as Katsuki had not said a word about liking him. “You like me that much, huh? Should’ve known a shitty Deku like yourself couldn’t resist me.”

Stalking towards his prey, because Izuku still had not sat down on the bed. And Katsuki would’ve preferred him spread out on the bed, legs so far apart, Katsuki had no issue in settling between them.

He trembled at the thought of having those thick thighs enveloped around his shoulders, pulling him further as he sucked him off.

“Whatcha doing, Deku? Didn’t I tell you to get on the bed?”

“Yeah,” Izuku replied, wrapping an arm around Katsuki’s neck. “I was waiting on you?”

Slowly Izuku lowered himself, pulling Katsuki along in the process. Katsuki simply indulged him, putting a knee on the mattress as his body was forced to follow Izuku’s movements. They shuffled around a little until Izuku’s head was posed on his pillow,

body splayed out on his All Might themed sheets. His legs were already spread wide, accommodating to Katsuki’s body as the other settled between them.

The arm remained around Katsuki’s neck, their faces so close, he could feel Izuku’s laboured breathing fanning against his face. Izuku was nervous. Katsuki could feel it in the way his body tensed whenever Katsuki moved a mere inch.

“Is this how you pictured your first time, Deku? Because this is definitely how I fucking pictured it. Me between your legs, soon with my cock stuffed in that tight little hole of yours.”

(This is going to be so long... 4k and counting)

“Maybe,” Izuku whispered, eyelashes fluttering lightly.

Katsuki stilled completely, as he stared down at Izuku. Maybe. Knowing Izuku had pictured Katsuki to be his first, to be the one to take his virginity, made Katsuki groan out loud.

He was the one who was supposed to have it. Show Izuku how to fuck someone properly. Take Katsuki dick like a champ and ride it like his life depended on it. Izuku wanted Katsuki to teach him all these things. Wanted Katsuki to claim his body and ravish it for all its worth.

“Fu-uck,” Katsuki gritted out. “I’m gonna fuck you so good tonight.”

Nipping at Izuku’s exposed neck, Katsuki kissed his way up to those inviting plump lips once more, swollen red already due to their last shared kiss. Katsuki claimed another one, coaxing Izuku’s tongue into his

mouth this time too. He knew Izuku was inexperienced, could feel it with the way Izuku’s tongue moved around uncertainly, not sure what to exactly do with it. Which in turn only made Katsuki hornier, sucking at the appendix.

Slowly he lowered his hips, putting his full weight on Izuku’s body. Feel their dicks press together for the very first time. Never had Katsuki had a cock this close to his own. But feeling it wetly sliding against his, he realised how much he loved it.

Their combined spilled precum made Izuku’s needy thrusting a lot easier.

“God, Deku,” Katsuki groaned as he finally pulled back from the kiss. “You gotta give me everything.”

“Whatever you want, Kacchan,” Izuku breathed in return, hips still making jerky little movements to get some friction out of Katsuki’s body.

“I need it all.”

His breath ghosted over Izuku’s skin, moving from his jaw, back to his neck, going down further and further. Katsuki’s remembered the round of a woman’s breast, but found a rock hard chest to be just as appealing, if not more.

The hard plain of Izuku’s breast was easy to graze teeth over, and once he flicked a tongue over the little nub, he found it standing up in no time. It was a lot harder than he had ever seen a nipple, and even more sensitive. But maybe that was just Izuku.

Maybe the little virgin boy could just not handle a lot of attention.

Blond locks were fisted by scarred hands, Izuku pulling at the strands whenever Katsuki bit down on a nipple a bit too roughly. The breathless moans that continuously fell from reddened lips said the nerd

didn’t mind it much though.

“You got nice tits, Deku,” Katsuki hummed as he moved from the left nipple to the right. “You like getting your tits touched, don’t cha?”

“Yes,” Izuku hummed, hazily looking down at Katsuki as he thrusted his hips up again. His dick only slid against Katsuki’s stomach now.

“Well, then you better get ready for the rest, shitty nerd. This was only the appetizer.”

Lips left the little abused nubs alone, red eyes greedily taking in the sight of Izuku getting more flustered by the second. It was time to move on. Take the next thing. Katsuki couldn’t waste time. Needed to take all of this.

So Katsuki lapped out his tongue, and dragged it along Izuku’s stomach and abdomen, his chin hitting the head of Izuku’s dick. Izuku’s hand had left Katsuki’s hair.

When he looked up, he noticed clouded green eyes looking at him, Adam’s apple bobbing again as Izuku swallowed.

They were treating new territory. Something Katsuki had never done either. Not that he’d ever admit that to Izuku. Not now anyways. Katsuki assumed he was going to rock at it anyway, and Izuku would definitely like it when lips were stretched over his girth.

Katsuki had always fancied a blowjob. Made anyone shut their tramp as well.

“You never had your prick sucked, right?” Katsuki asked, already knowing the answer.

Izuku shook his head, curls bouncing at the movement. Green eyes kept glancing down at Katsuki though, looking very

aroused as Katsuki moved lower and lower, hot breath lingering all over his heated length.

“But you do want your pretty little cock sucked, right?”

“Y-yes,” Izuku moaned, Katsuki dragging his tongue from the base up to the head of his dick as soon as the first syllable fell from his lips.

“What else do you want, Deku?”

Katsuki nosed the hard length, the musky smell of Izuku filling his nostrils. It still smelled faintly of Deku’s sweat, but more pronounced, deeper, making his head a little fuzzy as Katsuki nipped at the base.

“Everything!” Izuku moaned as he bucked his hips up into the touch again. “You promised, Kacchan.”

And that he kind of had, hadn’t he? Katsuki grinned widely again as he could feel Izuku’s neediness trembling all through his body, willing Katsuki to finally grasp his cock and

suck on it. Give him the best blow job Izuku would ever have.

Katsuki relented, nerves flaring a little, heart beating fast as he wrapped his fingers around the base of Izuku’s dick, and let his tongue slide over the head, getting his first real taste. It was salty mostly,

with a hint of bitterness. A taste he didn’t mind much. And hearing Izuku’s encouraging groan, Katsuki continued. Fold his lips around Izuku’s girth, and sink down lower and lower, until he could swallow no more.

“Oh god, yes. Oh fucking god, yes,” Izuku babbled, still watching Katsuki stretch his lips around him.

Sliding back up, Katsuki sucked harshly at the head, knowing how much he loved it when girls did that to him. And hearing the volume of Izuku’s breathing moans increase, said

that Katsuki was on the right track.

He kept up a slow pace, his throat still accustoming to the intrusion. But it felt good. The burn down his throat felt good. And once Izuku started meeting Katsuki’s slides with short snaps of his hips, Katsuki was forced to keep him down.

No need to choke on dick just yet.

Katsuki understood Izuku wanted more though. Quickened his pace by bobbing his head up and down faster, grazing his teeth over the base of Izuku’s cock. He knew the little masochist would like that. And the guttural moan that Izuku let out,

was enough of a confirmation.

“Kacchan, wait, I’m… I’m…”

There wasn’t much else that Izuku needed to say. His hips stuttered under Katsuki’s hold, trying to get as much friction out of Katsuki’s throat as he could. And for a moment Katsuki let him,

let Izuku take his mouth to spill his orgasm inside. Because fuck it all. He had made Izuku come already. Had done that. Had shown he was a pro at sucking cock, even if it was his first time. This was what he was made to do. Teach the virgin how to get fucked.

Izuku’s cum wasn’t the best of tastes, but Katsuki ignored it as he popped off the length with a final suck, a string of saliva still connecting him with the softening dick.

A feral grin broke out on his lips again as he looked up at Izuku, seeing how utterly destroyed he already was. A virgin was not ready for this kind of abuse, but Katsuki was not going to give up his position.

“Hey, nerd,” Katsuki spoke, catching Izuku’s attention again. “You better be ready for round two, because I ain’t stopping.”

And with that said he licked a strip from Izuku’s puckered hole all the way up to his balls.

(I think I may be too detailed for a thread?? But I'll try to finish this, this weekend, and then I'll also post it on AO3, because hell, it's a long ass oneshot now)

“Oh, fuck. Kacchan, just…” Izuku moaned.

“What’s the matter? Already begging like a little bitch, you virgin,” Katsuki teased, sucking lightly on one of Izuku’s balls right after. Making his point even further by torturing Izuku some more.

Katsuki could feel Izuku shift under him, the other reaching for the nightstand on his right. Dumfounded Katsuki followed the movements, utterly confused by Izuku’s sudden attention switch. He was about to snap at the nerd, when Izuku opened his drawer and pulled out

a little bottle of lotion.

A shaking hand was stretched out for Katsuki, holding out the little bottle. There was still an uncertainty lingering in those green depths, but Katsuki hardly noticed as he grabbed the bottle with a wide smile, eagerly taking it from Izuku to put it

to good use.

“You really are a fucking needy bitch. Wait till you have my cock inside ya. You never want anything else, but have sex with me.”

The words tumbled off Izuku’s shoulders as soon as Katsuki said them. Izuku didn’t care what Katsuki said, knew it had nothing to do

with what the other was actually doing and feeling. Hell, Katsuki had come here, just because he wanted Izuku. There was no need to feel insecure about this. Katsuki wanted this as much as Izuku wanted this. It had just taken Katsuki a long ass time to realise that.

Lips latched onto a patch of skin on Izuku’s thigh, sucking at it roughly as Katsuki uncapped the little bottle of lotion. A bruise bloomed nicely under his ministrations, marking Izuku for at least a few days. Every male student in their class would know. Would see Izuku has

had attention down there. Was taken by Katsuki, and no one else better dare come close.

Spreading the white cream over his fingers, Katsuki slicked them up nicely. This was going to be such a treat. Never had he done anything like this before. Yeah, he had fingered a girl here

and there. But they got wet on their own, and their pussies were ready to take cock once they got turned on enough. If he did a proper job, Katsuki could always easily slide in. But not one girl had let him do anal. All were too scared of a little pain.

Not Izuku though. Izuku would take it like a champ. Seemed to be thrilled to take Katsuki’s cock, if he had to believe those widened pupils taking in the sight of Katsuki slicking up his fingers.

“Your dick seems to be ready for the next round, shitty Deku,” Katsuki hummed.

Once more grown in size, Izuku’s cock laid fully flushed on his abdomen. It twitched as Katsuki lowered his fingers, the digits disappearing out of sight, right between Izuku’s legs.

“I just… Kacchan, I need…”

“Me?” Katsuki finished for Izuku, ego build up a little again.

His pointer finger circled the little ring of muscles, teasing at the puckered skin with the cold lotion. Izuku tensed a little, but soon sank deep into the pillow wearing All Might’s colours. Izuku was so pliable, ready to take everyone Katsuki threw his way.

It was making Katsuki delirious, having such a willing partner under him. A virgin that craved his cock more than he could imagine. This was unexpected, but Katsuki loved every second of it. Loved how well Izuku took everything. How much he craved it all,

and let Katsuki deliver it. And Katsuki just wanted to take more and more.

The first finger sank in without much pressure, the walls easily giving way for the digit to slide in. With a deep sigh Izuku opened his thick thighs further, giving more room to play around.

And play around Katsuki did.

It was fascinating to see the hole greedily swallow his finger. It opened up for him, just him. Taking it, sucking it further in, tightening around the digit. The walls squeezed and squeezed, and all Katsuki could think of,

was how it would feel around his dick.

It was nothing like the insides of a woman. Izuku’s walls felt more ribbed. Texturized. And Katsuki just wanted to know what it was like. More and more as he pulled and pushed his finger, moving it back and forth, in and out.

Those deep sighs Izuku had been letting loose, turned into full on moans once he got used to the feeling. It encouraged Katsuki only further. Moving his finger faster. Thrusting it in and out evenly.

But it wasn’t enough. Not if Katsuki wanted his dick to be between those

legs instead. And even if he enjoyed doing all these other firsts with Izuku, Katsuki’s aim was to take the grand prize. Be the winner of taking Izuku’s virginity.

So the second finger dipped in beside the first, stretching the walls a little further. At first they protested,

trying to squeeze the digits out again. But as Izuku relaxed again, his hole opened up so beautifully.

Stretching his fingers apart, he watched the hole widen for him. Showing off how much he would be able to take. Katsuki’s cock was thicker than that, but he was going to make

sure Izuku would be able to take it. Have those walls greedily suck in his cock, and clamp down on it like a vice. Keep it inside until Katsuki was milked dry.

He nipped at Izuku’s thigh again, the thought of having sex soon making his erection throb between his legs.

Rutting lightly against the All Might sheets, he relieved himself of some of the tension. Foreplay had never taken this long before. Usually Katsuki couldn’t be bothered. It didn’t matter. Now it mattered. No one else was going to suck Izuku off before Katsuki had.

No one was going to finger his ass before Katsuki had. And after this no one ever would. Only Katsuki could do it, because he was the best at it.

The two fingers turned into three, and then into four, the hole stretched so wide, it dripped lotion onto the bed.

Red eyes were still glued to Izuku’s puckered hole, watch it stretch wide, and then clamp down again when those fingers were pulled out almost completely. He hadn’t noticed Izuku’s voice growing strained. Hadn’t noticed how his arm was thrown over his eyes to hide himself

from the light. Hadn’t felt Izuku slowly meeting Katsuki’s thrusting fingers, trying to meet the pace the other had said. Until Izuku finally spoke again.

“Kacchan, please, just. I need…”

Peering up from between Izuku’s legs, Katsuki’s lips broke out into a familiar smirk.

“What do you need, Deku?”

They both knew what Katsuki wanted to hear. Had said from the beginning. But Izuku was reluctant. Reluctant to voice his thoughts of needing more than this. It was not enough. Really not enough. There was a place inside Izuku,

Katsuki’s fingers didn’t quite reach. The tips only grazed it a few times, torturing him with what could be. Something longer and thicker was going to help him out. And Izuku really needed it. Needed to come from it.

“Come on, Deku. What the fuck do you need?”

“Goddamnit, Kacchan. I need your dick. Just fuck me already!”

Katsuki didn’t need to be told twice. Ripping his fingers from Izuku’s hole, he watched the ring of muscles flutter, trying to close around nothing. It winked at him, seducing him to put something else in.

And Katsuki definitely was going to.

He crawled up between Izuku’s legs, getting in the same position they started in on the bed. Hovering over the other. The little virgin, trembling with need. Those green eyes lost their vibrance due to the dilated pupils.

It was glorious to be this high above him. Knowing this was all Katsuki’s doing. That he was allowed to be here. That he got a yes, instead of a no. Izuku must’ve had offers. Even a nerd like him was wanted at this age. But Katsuki was the one.

Of course he fucking was.

Aligning his length with Izuku’s prepped hole, Katsuki let a final grin grace his lips as he looked down at the virgin boy. “Ready, Deku? After this there is no turning back.”

“I don’t think you would let me, Kac-”

The final word was broken off, because at that point

Katsuki had started pushing in. Izuku was right. They already had reached a point of no return. Not that he wanted to stop there. Izuku wanted to see this through. Finally lose his virginity to the one he had wanted to all along. How many times he had fantasized about this moment

And finally they were here.

It was tight. So tight. Katsuki grabbed Izuku’s curls with both hands, placing his forehead against the nerd’s. And he groaned. Groaned loudly as he continuously pushed in, not halting at all to give Izuku time to adjust.

“Fuck,” Katsuki breathed out once he was sheathed completely. “Fucking shit, why didn’t we do this sooner.”

Below him Izuku still trembled, hands twitching as they reached to hold Katsuki, but couldn’t quite muster. His legs were wrapped around Katsuki’s waist, keeping him

firmly in place. Keeping him as deep inside as Katsuki’s cock could.

“I’m so full, Kacchan,” Izuku whimpered, sucking in a deep breath when Katsuki gave him an experimental thrust.

“You know what you are not,” Katsuki taunted. “You ain’t a virgin anymore, Deku.”

As emphasizes he wiggled around a little, letting those walls know how full they actually were. Stretching so nicely around his dick, hole fluttering around the base of his cock.

“I’m gonna tell everyone, Deku. Everyone will know you’re no longer a virgin,

and that I was the one who took it from you.”

“Okay, Kacchan,” Izuku whispered, taking in a deep breath. “Just don’t tell them how good it was. They can’t know. I don’t want them to know.” Izuku was shaking his head, tears pooling in his eyes. He was riding a high he had never

experienced before. “They can’t know how good you are, okay? I don’t want to share.”

Katsuki’s heart fluttered again strangely enough.

“Fine, shitty nerd. If I get to keep fucking your tight little pussy, then I won’t tell anyone how fucking great we are.”

“You can fuck me whenever you want,” Izuku babbled, eyes closing as Katsuki finally started sliding out further.

With a quick snap of the hips, Katsuki was fully inside, but didn’t remain there. The friction was too great. The ribbed edges of Izuku’s walls did wonders to

Katsuki’s dick. This was so much better than any girl he had ever fucked. Nothing could compare to this. Could compare to the rock-hard body below him, taking every thrust so easily.

If Katsuki could just keep doing this for the rest of his life, then he’d be a happy guy.

His thrusts came faster and faster, hips snapping forward to sheath himself completely repeatedly. Izuku’s head trashed from left to right on the pillow, unable to keep it all contained. The sounds of skin slapping against skin echoed through the room,

but was overrun by the moans Izuku let out.

Izuku was loud, they both were loud. The heat around Katsuki’s cock caused him to moan too. And he was not bound by embarrassment. Wanted everyone to know he was here, taking Izuku’s hole as if his life depended on it.

And all Izuku cared about, was how the head of Katsuki’s cock kept rubbing against that sweet spot. That one that Katsuki couldn’t quite reach before. But now it was perfect. Tantalising.

Any image Izuku ever had about losing his virginity, couldn’t live up to the real deal.

Never had he expected it to be this glorious. And he couldn’t help but agree with Katsuki, wonder why they hadn’t done this sooner. He had really been missing out.

That warmth coiling in his abdomen came way too soon. Normally Katsuki lasted quite long. Could hold out until he

had fucked someone for quite a while. But this was just enough. He was pushed closer to the edge with every thrust. Every move of his hips slamming against Izuku’s ass.

Thankfully Izuku was there first, his whole body going rigid, walls clamping down on Katsuki’s cock so

harshly, he could no longer move. They squeezed and squeezed as Izuku released his second orgasm all over his stomach, the scream he let out surely reaching the end of the hallway while they were at it.

When those walls finally loosened, Katsuki’s hips could only sputter,

unable to keep pace as Katsuki’s own orgasm wracked through his body. He spilled his seed deep down Izuku’s hole, pushing his cock in as far as it would go, forcing it to stay there until he was completely spent.

Collapsing onto Izuku’s body, Katsuki tried to catch his bearings

This had been something else. Couldn’t quite wrap his mind around it. All he knew was that they needed to do that again.

“So how was that, nerd?” Katsuki said softly, lifting his head up to look into hazy green eyes.

A bright smile formed on Izuku’s lips. One Katsuki had not witnessed in a very long time. It was sweet, soft around the edges. “It was amazing, Kacchan,” Izuku said giddily. “I’m glad it was with you.”

In return Katsuki dipped down for a kiss, making sure that smile would

disappear, swallowed by Katsuki. Taken by him. Because that smile was only for him. No one else needed to see it. And so he kissed him. Deepening it only to make sure Izuku knew who he belonged to. It was less rough then before. Lazier, softer, better.

Things stirred back to life as they kept it up, which Katsuki didn’t mind. Fuck if it was a school night, he was going to take Izuku’s ass as many times as he wanted. As long as it was his, he was going to take it.

…

“Deku-kun, you don’t look so good. Did something happen?”

Dark circles had formed under Izuku’s eyes. He had been groggy all day, hardly able to process the information they had gotten in class. His classmates had been worried, seeing how he walked a little funny. Some seemed to know. The ones he shared a hallway with.

They shot him knowing looks, but avoided him like the plague. Katsuki’s dark looks may have to do with that.

“Ah, I’m fine Ochako-kun,” he replied, rubbing at his face to will away some of the tiredness.

“Are you sure? Maybe you should go to bed. I can come by and check up on

you to see how you’re doing. Can’t have you getting sick.”

An arm was wrapped around his shoulder, body pulled close to someone else. Izuku didn’t need to look up to see who it was. The memory of his fingers and lips were still very apparent on his body.

The hickey just below the collar had been very difficult to hide.

“No can do, Round face,” Katsuki interjected, feral grin on his lips as he tugged the other even closer to himself. “He ain’t got the time to play around with you.”

“I think Deku-kun can speak for himself.”

The girl crossed her arms, shooting a challenging look Katsuki’s way. Apparently she had not heard the rumour yet, which only made Katsuki’s ego grow larger. Oh, how he was going to tell her, and everyone else that currently occupied the common room.

“Oh, shitty Deku can speak for himself, but the answer is the same. He ain’t got time for you, because he is playing around with me. And with playing around with me, I mean I am fucking his brains out. And only I am fucking his brains out, you got that?”

Fin.
