Katsuki wasn’t angry…he wasn’t.

Something so mundane as angry couldn’t possibly have covered the amount of boiling, seething, raw rage, which, to no surprise, only Izuku seemed to manage to get out of him in his classes.

He had noticed a change in Izuku’s demeanor lately. Katsuki knew the kid was getting bullied, heard it in the hallways and in the campus gym; something so small as him being a virgin- not sleeping with anyone because just like in high school, he struggled to fit in. There was a reservation in class that Izuku had from it, he shied away from answering Katsuki's questions and checked himself with a flinch when he realized he was muttering to himself.

It was unfortunate he wasn’t allowed to be a little…unprofessional with his students.

Specifically Izuku.

There was just something about him that caught Katsuki's attention and held it without fail. He was a little obsessed with the freckles on his face, those lovely lips opening when he realized the answer to a study guide question. Obsessed with how even though he dressed a little...not great, his body was to die for. And yeah, Katsuki caught himself staring at Izuku a few times...others as well, and if it made him a little jealous? So what, he would just cry about it with his hand around his cock and his mind filled with images of Izuku's lips wrapped around it.

Didn't make it any easier on him when he caught Izuku staring at him doing squats from the mirror out of the corner of his eye.

These things were not frequent, it made Katsuki poke and tease at him, hoping to elicit some type of response but it hardly ever gave him what he wanted.

But when Izuku walked into his class one day with a pep in his step and a little sway in his hips that had Katsuki tripping over himself, he should have started to dig deeper then. But, who was he to jump to conclusions? It certainly wasn't what he would find out.

He didn't, he wouldn't. He left it well enough alone and enjoyed the boost of confidence Izuku seemed to have, letting himself soak bask in it. Started to wake up earlier with coffee just to make sure he was fully awake and alert when Izuku came to class in those stupidly tight pants.

So when, after winding down from a long day and just wanting to watch some porn on a website that had exactly what he wanted ( See: twink with fat ass gets bred.), he came across a live show with creamy thighs and a toned back with freckles scattered deliciously across their skin, it was hard for him to not jump to conclusions. The camera showed off a gorgeous body, shoulders down and the guy only typed a response before getting himself prepped up and ready with a toy.

Katsuki got into it quickly, his hands palming his cock as he watched the nicest ass he's ever seen bounce up and down on a purple dildo. The way his ass jiggled was obscene.

His eyes closed, mouth parting just a bit, letting himself fall into rhythm with the wet squelches of that ass making room for something so large. Katsuki found himself pretending it was Izuku riding that dildo, riding it just for him and showing it off to extras who would never get to feel it. It was a carnal need at this point, the semester was still not even halfway over and every single fucking night was spent thinking about pale, freckled thighs wrapped around his waist.

Katsuki's hand went harder, faster, and kept up the pace with the guy on camera. It was so easy to hold the imagery, to pretend that this was everything he wanted. It wasn't until he heard the breathy "Kacchan" in that fucking- he knew that voice, that he came, his cum shooting him square in the eye and now here he was.

Horny. Dazed.

And so fucking angry he didn't figure it out from the get-go. So angry that Izuku was doing this for other people and not him.

With his one good eye, Katuski could see the 50 or so people text praises to him; complementing the way his thighs looked as he came, talked about how pretty his body was and how lucky whatever man that got ahold of him was. People asked for private shows, and offered stupid fuckin' money and Katsuki almost made fun of them for it until he realized that shit, he would do it too. He'd give his entire annual salary just to have Izuku do this shit for him and only him.

"Fuck.." Katsuki grumbled when Izuku lifted off the toy, rubbing furiously at his eye that was burning so bad and how fuckin' embarrassing was it that he came like a teenager over this? No matter- he wasn't gonna sit in shame over it. Everything just made so much more sense now; the confidence, the sway...the one or two people calling him ugly for 10 minutes during class had nothing on the countless men calling him pretty and encouraging an orgasm. Turns out he looked stunning with his body tensing and cum dripping down his pretty cock.

Shit, even Katsuki would be riding on the high of praise. It was clear Izuku did too.

His fingers were on the keyboard before he even really knew what he was doing.

LordExplosionMurder: Lick the cum off your hands.

Izuku stopped for a moment, leaned to read the chat, and then he did.

LordExplosionMurder: Good boy. How much for a private show?

Maybe it was the name that threw Izuku off, though he couldn't see his face, he could see the upwards tilt of his chin. The username was for sure off-putting, probably because it was more normal than the mr.twinkdestroyer or fatcock6969 people spamming the chatbox.

FreckledTwink: @LordExplosionMurder I've never done one...really just started doing this so just requests for now.

LordExplosionMurder: Ok.

LordExplosionMurder: How does 500$ sound? Just for 20 minutes of your time.

Katsuki smirked at the breathy 'holy shit' he heard from his laptop.

FreckledTwink: That's a lot of money.

Slutminari: Do you top?

Katsuki chuckled.

FreckledTwink: Ew no lol, just bottom :)

LordExplosionMurder: You're worth it. Think about it, but you're wasting your time on these extras. Thanks for the show, freckles.

With that he logged off and closed his laptop, not allowing himself to see or hear Izuku's reaction. His issue now lies in the overwhelming urge to fuck Izuku into whatever surface he can until his ass remembers the shape of his cock.

Screw the college policies or whatever- there wasn't a fat chance in hell he wasn't going to do his absolute damnedest to get a piece of that ass now that he's seen it.

But, did Izuku like older men? What type of guy was he into- was he even into men in the first place?

It was a stupid question, to his credit, the briefest of insecurities bubbled up but then Katsuki remembered who he was, remembered what he looked like and how people looked at him.

He was a fucking catch and he's never not gotten what he wanted.

He just has to get through the semester.

So he sits and watches each stream, it's sporadic and unscheduled, but he's subscribed and is a little too eager when he gets the notification that 'Freckledtwink is live again.

Unfortunately, for as proud as he was of keeping himself put together at work, he does slip up. It was a total accident, weeks had gone past since, the semester flying by and Izuku never once responded to his offer of a private show nor was he aware that it was his calculus professor, out of all people, asking to have it.

"See ya later, freckles." A total slip of the tongue, Katrsuki's heart hammered in his chest the moment he let that name slide off his tongue. For a moment he thought that Izuku didn't hear him, he got no response. But Katsuki turned his head to look at him- was quick to notice the way Izuku's shoulders tensed at the name and the way his eyes were practically bulging out of his head as he turned around to look Katsuki in the face.

Laughable is what it was. That face of realization. Katsuki was so fucked.

Even more so when he came home to a message in his inbox.

FreckledTwink: I'll do it.

FreckledTwink: The private show.

LordExplosionMurder: Yeah?

FreckledTwink: Never done this before though.

FreckledTwink: Hope I don't dissapoint.

LordExplosionMurder: You won't. Turn on the camera.

Izuku did as he was told, the adjacent screen flickering to life as soon as the comment was sent, his clothed body coming into view. Katsuki's cock was already twitching in his pants at how quick Izuku was to obey. This would be good. He was showing the usual amount, keeping the standard discretion as he would a public show, and Katsuki almost had the balls to complain about it but, in due time. He was going to work through this, let things flow as they should and then finally get his hands on Izuku and ruin him for everyone else.

LordExplosionMurder: Good boy. Undress for me.

Izuku's breath hitched at the pet name, but he stands, his fingers clenching at the edges of his shirt before tossing it over his head. Katsuki typed out a quick stay, full-screened, and upped the quality of the stream just so he could get a good look at that gorgeous body. There were freckles everywhere dotting the pale expanse of skin like stars, Katsuki wanted to count all of them.

With his tongue.

Izuku's body was toned, something Katsuki appreciated. Those slutty tank tops or those stupidly hot yoga pants he wore at the gym had nothing on this, they could never do his body justice. He loved it when someone took care of themselves, s'a shame people on campus don't get to see this. They just run their ugly little mouths about things they don't know.

LordExplosionMurder: Pants.

Watching Izuku take his pants off was an experience. He did it slowly, putting a little more pressure as the waistband got caught on the rise of his ass. Intoxicating was the word for it, Katsuki found himself leaning forward just to get a better look, he didn't want to miss a thing. He caught the slick shine of lube on Izuku's inner thigh as he kicked the pants off and this time, it was Katsuki's turn to lose his breath.

Izuku was wearing white lace, fitting his form so well he almost, almost missed the bright blue diamond of a butt plug nestled in his ass. He swallowed, hand flying down to his cock, fingers tight around it- because that? That was going to make him come before they could even get this over with.

How embarrassing , Katsuki thought to himself, that he allowed his desires to manifest this strongly. Izuku lifted his leg, held by one hand to show himself off, and fuck, everything about him just got prettier and prettier.

LordExplosionMurder: You're so beautiful. Do you know that?

He could see the ghost of a smile on Izuku's face and the sudden bloom of red on his shoulders as he blushed. Katsuki was falling deeper by the second.

LordExplosionMurder: You have your toy?

Izuku nodded.

LordExplosionMurder: Good. Take it out and show me how useful that pretty little mouth is.

Hesitation. Katsuki could see it in the lines of his shoulders, but he was struggling to understand how he could ride that very same toy for dozens of people but have some type of...setback now. If anything, the stupid amount of money Katsuki was offering should do everything but cause a dilemma.

LordExplosionMurder: Do it.

LordExplosionMurder: I know you want to. You know you want to. Let me see how good you can be for me princess.

Izuku shivered. Maybe it's because he's never done this before that he was so nervous, Katsuki wondered if he'd be this nervous in real life. If instead of an obnoxiously bright purple dildo that he was going to fuck his mouth with, it was Katsuki's cock. Izuku is hard under the panties, the head of his cock peeking out from the white band, straining and red and so fuckin' pretty. He took a deep breath, steeling himself and Katsuki could do nothing but watch like a hawk as Izuku gathered his nerves.

He turned and reached for the dildo, the twist of his body showing off his ass. The slut. Izuku turns back then, one hand gripping the dildo tight while the other reached towards the camera to adjust the angle.

The lens was pointing a bit higher, it seemed, enough that Katsuki could make out the tip of his nose and those lips were now at the center of his attention. He could see the splatter of freckles on his cheeks, once again finding himself oddly obsessed with them.

Izuku had a face that would look so pretty covered in cum, covered in Katsuki's cum.

And as Izuku pressed the toy to his lips, kissing the head of it then lower, lower, and then licked a stripe back up, Katsuki realized this wasn't a want anymore, not a simple craving. Five minutes into this and he needed to put his hands on him, to be inside of him and make him his. Katsuki pulled his own pants down, his cock smacking heavily and straight against his stomach as he watched Izuku work the tip into his mouth.

Once again he raised the camera angle, just barely below his eyes. Wanted Katsuki to see more of himself, he thought.

LordExplosionMurder: Take more.

It was terse, sharp, and commanding but Katsuki went into this hanging onto a thread, barely. A thread that had quickly frayed and was threatening to snap as he started a slow pump of his cock watching Izuku do as he was told. Katsuki was leaking so much pre he didn't even think to reach for lotion.

What a fucking joke that this kid got him so riled up.

Izuku takes more, more into his mouth and gags a bit when the tip hits the back of his throat. Katsuki's balls twitched, his perineum already pooling with heat. He could record that literal one-second worth of noise, play it on repeat and come.

Over and over and over. He needed to hear that. He needed it to be his cock that Izuku was choking on.
And it would be.

LordExplosionMurder: Again.

Izuku moved back on it, cheeks hollowed before he popped out with a wet noise. Katsuki groaned at it, threw his head back when Izuku does it again but takes just a fraction more. It's clear he hasn't done this before, clear that he doesn't know the weight of a real cock in his mouth, in his throat, where it belonged. Izuku's hardly halfway, and so is Katsuki when he sends out another message.

LordExplosionMurder: You're doing so good for me. So easy to imagine you taking my cock like this.

LordExplosionMurder: Go faster.

Izuku does.

LordExplosionMurder: Deeper.

Izuku does. His throat bulged as he pushed past his gag reflex with a tear sliding down his cheek. Katsuki so desperately wanted to lick it up, kiss it back into his mouth.

LordExplosionMurder: I wouldn't let you take your time, baby. A mouth like that needs to be used, claimed. I'd make you take it. Do better, I know you can...relax your throat and take it all the way.

And Izuku, like the good little student that he is...always is- does. His throat is obscene now, making space for something so large, something that's never been there before. Katsuki's hand is moving faster, his free one coming to rub slowly around a nipple as he imagined himself gripping Izuku's neck tight and feeling his cock make room in it in his throat.

LordExplosionMurder: Would you let me cum down your throat? On your face?

He sees a quick nod, followed by another gag. Izuku pulls off of it, slowly, bobs his head forward, and takes it back into his throat.

What a quick learner he was.

LordExplosionMurder: I bet you'd love it. You seem like the type to just take it all, do as he's told, and then ask for more.

LordExplosionMurder: I'd fucking coat your face, make you sit there with it on your face just so you know who you belong to. I want to ruin you, freckles.

Izuku moans then, suddenly, Katsuki had to let out a laugh as cum leaks out between the threads of his panties. His hips are thrusting forward, grinding down against the plug that Katsuku had forgotten about with more noises sounding like they were being ripped from him and it does something dirty to Katsuki's core.

LordExplosionMurder: Fuck you came from that? You came for me...holy shit. What a good boy you are. Keep it up, I'm almost there too.

LordExplosionMurder: Fuck yourself with the plug.

Izuku responds right away, because of course he does, angled himself to show off his ass more, his thighs and stomach flexing as he held himself up in an arch. His one hand fucked fucked the dildo in and out of his mouth, Katsuki hearing the gagging more than seeing it, not that he was complaining. His other hand was playing with the plug, fingers gripping the diamond tight as he pushed and pulled it in and out.

In and out.

Katsuki was mesmerized, watching the rim of his ass stretch as the widest part of the plug tugged at it before Izuku pushed it back in with another moan. Over and over again he did it, the wet sound of lube squelching as Izuku fucked himself- the sound of his throat pushing back against the toy.

It was overstimulating.

Like the first time, Katsuki matched the movement of his hand with Izuku thrusting the plug back inside himself. On a rough thrust, Izuku seemed to press the plug impossibly deeper, the diamond of it starting to go inside and it was then Katsuki realized that Izuku was coming again.

Katsuki was quick to follow, his toes curled and his head pushing back into his pillow with an empty moan. His cock twitched violently, somehow finding the strength to close his eyes as he once again shot on his face. Katsuki kept stroking himself through it, painting his chest and his stomach with his cum until his cock softened.

His chest heaved as he caught his breath, eyes staring blankly at the ceiling as he contemplated his life. He turned his attention to the screen, watching as Izuku struggled to get the dildo out of his mouth. It seemed he was in just as worse of a state as Katsuki was, his body was flat against his bad, back rising with heavy inhales.

He did so well. So so good, just for Katsuki. He told him such.

Izuku murmured a thank you.

LordExplosionMurder: Can't believe you did all of that for some random- can't believe how fucking sexy you are freckles.

Silence stretched for minutes, but Katsuki couldn't find himself looking away, aside from sending the payment through, in hopes that maybe Izuku fell asleep. His brain went alight with the wondering of what Izuku would feel like between his arms, against him as they slept. Such a peaceful picture it provided, it was comforting. Just thinking about it made him tired.

Izuku mumbled something under his breath, much too quiet for his sleep-addled brain to pick up on. His phone dinged with a ‘Payment Rejected’ notice.

LordExplosionMurder: What?

"You're not a random person," Izuku said, louder this time, with more confidence. "I know who you are."

Fuck..

LordExplosionMurder: And you still did it anyway?

"Mhm." Izuku stretched languidly, the camera showing his face and he could swear he saw a glint in Izuku's eyes. "Can't believe you've been watching me for so long...and you just- you never did anything about it. Never said anything."

LordExplosionMurder: Shit.

LordExplosionMurder: Do you want me to do something?

"Yeah," Izuku looked straight at the camera, his eyes seeming to pierce through Katsuki's own "I want. I've wanted you to for a while, even before I got in your class, the whole campus talked about how hot you are and I’m no different. Want you to do everything with me."

Katsuki swallowed, licking his lips on reflex. It was a different type of burning knowing that the person you've become obsessed with wants you back. Has wanted him for some time now. It sent a shock down his spine.

LordExplosionMurder: Tomorrow. Start a show, get yourself ready for me and I want you face down, ass up.

LordExplosionMurder: I'm going to fuck you until your lungs give out and we're going to make every single one of those extras watch.

Izuku eyes got a little dazed but he nodded. "Ok."

Work was never boring for him, not by a long shot. He enjoyed teasing the students, picking at 'em, and forcing them to think about real-life things.

But holy shit, the day dragged on so slowly and Katsuki was buzzed with energy, feeling like his skin was going to peel off from it. His class with Izuku had ended, the other leaving a sticky note with his address on it and a stupid little green heart on it.

That was two hours ago, Katsuki could only hope to imagine what Izuku was getting up to right now, what was getting up into him.

He was sitting through his last seminar and presenting how shitty the Pythagorean theorem was in a real-life application when he got the notification.

From Freckledtwink: Hey, just started streaming. Want to join?

When class concluded he was half-hard in his pants, his thigh moving to adjust himself as his students gathered their things to leave. Katsuki followed suit, his back turned so they wouldn't see the bulge in his pants when one of his attendees came up to him.

"Professor, would you mind taking a look at my thes-"

"No," Katsuki interrupted, "Get a job, I have somewhere to be."

Izuku was so fucking wet.

He paused at the entrance of his bedroom, just letting the seconds fly by as he took in his fill. Izuku was presenting just like he asked, face buried in his pillow, muffling the moans while his back was arched and his ass was up. Two fingers were pushing inside of himself, stretching and pulling for the camera directed right at it. There was a faint, shimmering shine of lube covering his ass and his inner thigh.

Katsuki could see the comments flooding in, just a bunch of shitty people typing dirty things they would never be able to do. He let his footsteps fall heavy against the floor, each step Katsuki took was another piece of clothing he removed until he was standing at the edge of the bed in black briefs.

Izuku's head was tilted just a bit, so he could get his eyes on Katsuki. His pale shoulders reddened with a deep blush.

Katsuki couldn't wait to leave bite marks there.

Without thinking, his body moved forward- let himself get into the frame as he pushed his face into Izuku's ass and licked a slow strip from the back of his balls, pressing into the tight heat of Izuku before he could even react. Moans shook through the boy's body and Katsuki ate him out like he was starving for it, not caring for the taste of lube but reveling in the feel of his stubble dragging across the sensitive rim, of his tongue finally tasting the deepest part of him.

Izuku tried to twist away, moaning and writhing but Katsuki snaked his arms under and around Izuku's thighs, pulling him in closer and nipping at his ass in warning. "You taste so good, baby. Let me have this...let them watch what they want." Compliance followed immediately and Katsuki let himself fall into pace.

He kissed, sucked, and nipped at Izuku's rim, pushing his tongue so deep it had Izuku grinding his ass back against his face. Katsuki was already a possessive man, but just from this? He wouldn't let it go- couldn't let it go. Izuku hissed and squirmed as Katsuki spread his cheeks apart, and rubbed his face against him, letting his beard mark and turn the skin between them red. His arms squeezed Izukus's thighs, tight, feeling that flesh against his, and christ he couldn't wait anymore to get inside of him.

"M'gonna give you what you need. Ok, princess?" Katsuki bit his ass hard when Izuku nodded, let his teeth bruise into the skin, and gave himself a moment to appreciate the mark. He licked a devastating stripe from Izuku's perineum, over his ass, and up his spine, letting his body slowly cover Izuku's before biting down the end of his ear.

"Everyone's going to watch as I fuck you, you ok with that?"

"Mhm..." Izuku moaned into his pillow, Katsuki sucking a bruise just behind his ear.

Katsuki slid his briefs off, letting his cock rest between Izuku's cheeks as he thrusted against him. "Do you know what's going to happen when I do? What that means for me, for you?" His hand comes under Izuku's chin as he nodded, gripping tightly as he turns his face towards him.

"You're gonna be mine, Izuku. Do you understand?"

"Yeah."

Katsuki shifted his hips, letting the head of his cock catch against Izuku's rim.

"I didn't think you wanted me I- I thought I was so obvious about it." Izuku moaned, his words stuttering as Katsuki slowly pushed his cock in.

"I thought about it," Katsuki pushed deeper, the hand not gripping Izuku's chin gripping bruises on his waist as he held him still. "Saw you looking at me at the gym, clearly you didn't see me watching you, princess. Been wanting this for months."

"You have it," Izuku whispered, his lips ghosting Katsuki's.

"I do. M'not letting this go either." And then Katsuki leaned forward, pressing his lips against Izuku's soft mouth. It was gentle at first, Katsuki's tongue tracing the shape of Izuku's lips, asking for permission.

Izuku opens up then, immediate and submissive, and Katsuki can't help but take and take and take, his cock pushing deeper with every twist and turn of their head until his hips were flush against Izuku's ass. He couldn't help but take it with his own tongue, claiming yet another part of Izuku's as his before he pulled out with Izuku's lower lip between his teeth.

"Can't not be fucking you anymore." Katsuki's mouth was hot against the column of Izuku's throat, his teeth nipping and pricking at the soft skin there until the indents of his teeth were left. "Ready?"

"Yeah I- fuck!" Izuku bites the skin between Katsuki's thumb and index as he begins to pound into him. His brows clench tight in concentration, focused solely on imprinting the shape of his cock inside Izuku.

Every thrust is brutal, Katsuki was well aware of that, the harsh grip on his body keeping Izuku from slamming into the headboard as he kept fucking and taking what was his. All Izuku could do was brace his arms against the dark wood and curse into Katsuki's hand as he bears down into him.

Katsuki was overwhelmed, his face buried in the back of Izuku's neck, biting and sucking, his tongue soothing the deep marks and indents. The taste of Izuku's sweat on his tongue, the sound of him half-moaning as Katsuki pulled out before being choked off when he slammed home pushed his body into senses he couldn't articulate. His beard was rough against the sensitive skin, rasping it till it turns a blistering red. He'd mark this kid up for all he was worth.
Izuku was going to make a pretty sight covered in bruises that he left in the morning.

Just the thought of it got him going more, his thrusts turned impossibly hard. Katsuki glanced to the left, saw the viewer count hitting well over a hundred and the floor of comments pouring in did something fierce to his ego.

Cockdestroyer: 'Holy fuck he can take a pounding.'

Slobonmyknob69: What's the tops name!'

Shindo: 'Twitter? OF?'

Togachako: 'He looks like he's about to cum holy shit...just from getting fucked!'

"You're so fucking good for me, Izuku. Always so good for me." Katsuki groaned into Izuku's ear, pressing his chest against the boys back even harder. Izukus' ass takes him so perfectly, so hot and wet and all his. He never wanted to stop fucking him, having him like this. He wouldn't.

Izuku tries his hand at sarcasm, but Katsuki was quick to the punch and fucked the words right out of him. He can hear Izuku's labored breathing, can feel the stutter of his heartbeat through his back and he was sure Izuku could feel his too.

Katsuki keeps pounding him to him, another shift of his hips and a well-placed thrust had him fucking his cock against his prostate relentlessly, felt the way it had Izuku falling apart underneath him.

"I'm gonna come, I need- Katsuki, I need to come." Izuku sobbed.

"Do it. Let me feel you come on my cock." Katsuki soothed, fucking in harder, one arm wrapped around his chest and the other pressed against the mattress holding them both up. He could feel one of Izuku's hands wrap around his forearm, nails digging marks into his skin.

Izuku came then, thighs tense and knuckles white with his grip on his sheets and Katsuki's forearm as his orgasm tore itself from his body, his walls clenching so tight on Katsuki's cock it almost hurt. He turned Izuku's face towards him, throat tight as he saw just how gone Izuku was on it.

His teeth sank into Izuku's shoulders as he chased his own climax, biting down just on the side of too hard, too painful he knew but he couldn't care as his balls tightened and his came thick ropes inside. Izuku milks him then, involuntarily, squeezing down with every little aborted thrust that Katsuki gives as he pushed his load deeper, so much deeper.

Izuku's breath does that little hitch again as Katsuki whispered dirty promises in his ear, how he was going to be dripping his cum for days and rocking through that too-high feeling of another insane orgasm. Those small movements were incessant, grinding against that spot deep inside him, Katsuki could feel another orgasm from the way Izuku clenched down on his cock again.

Izuku's arms gave out, his body slumping to the bed, and Katsuki's body never lost contact with it. They fell flat together, his body pressed Izuku's down into the mattress. Katsuki was repositioning them as Izuku came to, his ass squeezing again and it was amusing watching him come back into his surroundings.

"So good for me, Izuku. You took it so well, so proud of you, baby." He kissed the mark on his shoulder and kissed it again with another praise that left Izuku preening.

Katsuki’s cock rested heavily inside of him, the warmth as his cock softened inside was indescribable, like it belonged there. They got lost in each other, Katsuki's hands roaming down Izuku's body, digging into the muscle of it as he talked him through how good he did. How good he was for Katsuki, how he was going to treat him like a princess and fuck him whenever he wanted. Whenever he needed.

A ding reminded Katsuki the stream was still rolling, how he managed to blinder it was beyond him.

With another kiss, he whispered “Look up at the camera, princess.” in Izuku's ear.

Izuku shook his head no, gently, but he asked again, giving a little thrust despite being soft. "C'mon- let em see what I did to you. They know how good you treated me, right?"

The chat responded in kind, ding after ding of people asking for a second round, talking about how hard they came from watching them.

So Izuku did- Katsuki watched as those eyes settled on the lens with a smile. Izuku still seemed unfocused, all for the better, he supposed. His cock was twitching back to life again as he started thrusting- he never did pull out. Katsuki let Izuku mumble what he needed to, let him complain that he was feeling gross and sticky between his thighs. Katsuki didn't say a thing, not a fucking word as he felt his load drip out past his cock to Izuku's balls. That was his cum leaking out of Izuku's ass, no one else's.

Izuku interrupted his gloating with a quiet demand. "Carry me to the shower."

"Hah? Now?"

"Yes! I feel gross and I'm tired and I have class tomorrow and holy shit I have your class tomorrow what am I supposed to do- what if I get reported. No, wait, what if you get reported to the ethics office? You could lose your job and-" Katsuki silenced him with a finger to his lips, leaning over to press a kiss on his forehead.

"Relax you fuckin' nerd no one's gonna say anything. I'm certainly not, no way in hell would I ever miss a chance at ogling your ass in the hallway now."

Izuku laughed a gorgeous sound that had Katsuki's blood roaring in his ear and his heart skyrocketing. Katsuki buried his face in his neck and smirked, he wanted to hear it more. "I don't know if I can be normal about this."

"Then don't."

"But what if-"

Katsuki pecked his lips before pulling out slowly, mourning the loss of Izuku's heat around him. "Stop worrying, shut your mind up for just a second. We fucked, we're going to do it again and again so why bother? You have two weeks left before you pass my class n' then you're onto the next- after that? We can do whatever you want."

Izuku sat up "Whatever I wan- hey woah!" Katsuki let out a hearty laugh as he carried Izuku bridal style into the bathroom, and sat him down gently on the sink, turned the shower on, hands testing the water every so often as he stood between Izuku's legs.

"Yeah, princess...whatever you want."

"What if," Izuku chewed at his lip, Katsuki had the carnal urge to fuck his mouth but- time and place "What if I want something more?"

"Like dating?"

"Yeah." Izuku swallowed.

"You want to date an older man? You sure you're cool with that?"

"Yeah," and this time, it came out with more confidence. Katsuki smirked, raised Izuku's hand to his mouth, and nipped at his fingers.

"Good, I had no intention of letting you go anyway. I told you you’re mine and I meant it, ya hear?"

Izuku nodded.

Their shower was long and gentle, Katsuki taking his time washing Izuku's hair and fingering him clean, all the while telling Izuku all the nasty things he was going to do to him later. Sleep took them quickly, but the morning was just as he expected it. Katsuki watched Izuku rub at the bruises on his neck, and his shoulder before he set a seething glare on Katsuki whose arms were thrown behind his head with a smug smirk. Izuku tried to tackle him, wrestled, and laughed but ultimately Katsuki had him pinned to the mattress.

And maybe Izuku looked up at him from beneath his lashes, just begging for it.

And maybe it sparked a round two because Katsuki was a sucker, it turned out, when Izuku had his eyes on him.
