Izuku was kind of excited for today. It's the day after Valentine's Day, because Izuku got too much attention, everyone kept distracting them and trying to pull Izuku away to be able to confess, he wasn't able to go out on a date with the blond but he can now! Well not really, he doesn't want to go out on a date with Kacchan, after all his parents are gone for the entire day!

He hasn't been able to get too touchy with the blond since he gets too embarrassed but not today! He... he really wants to feel that kind of stuff again, they only did it once and it's a special occasion so it should be fine. And maybe he kind of wants Katsuki to perv after him too. Katsuki was a pervert, he likes it a lot when Izuku shows skin but the blond doesn't touch him at all, probably scared of scaring off Izuku, Kacchan needs to be rougher with him and show him his place.

Which is why he wears Katsuki's hoodie and the shortest pair of shorts he can find. He did some research the other day, some people can get turned on by stuff like this! He wears black socks that reaches up just below his knees and brown boots his mom got for him the other day, Izuku doesn't mean to brag but damn he looks cute, and if Kacchan doesn't want to ravage him after this he'll definitely think that something is going wrong here.

"Izuku?! W-What are you wearing?" Hisashi asks, his face a bit red.

"Do you think it looks cute, dad?" Izuku asks, trying to look as cute as he can, his father quickly nods.

"Are you going out today?" Izuku nods.

"I'm going to Kacchan's place today." In an instant Hisashi suddenly looked like he's seen someone eat a pile of shit.

"...T-That's great, son." He says, a strained smile on his face, Izuku thinks he should learn to control his facial expressions better, his eye was twitching and he looked about ready to murder.

"Mhm, Kacchan's parents are gone, we have the entire house for ourselves!" Izuku exclaims, a bit excited, Hisashi looked even more disgusted.

"Hahah... I... see..." Hisashi smiles, "if he ever does anything that you don't want you can tell me and daddy will beat him up for it, okay Izuku?"

"Why would Kacchan do something like that dad? We're only hanging out." Izuku says, looking innocent as ever. Hisashi doesn't reply, rather, quickly going in the kitchen instead to look for his wife. A few moments later, someone ran on the doorbell, Izuku quickly ran and open the door, quickly hugging the person outside.

"O-Oi Deku! We'll end up falling or some shit! Calm down!" Katsuki mutters, stumbling backwards as he caught the greenette.

"Kacchan, you came early!" Izuku giggles, hugging his boyfriend hard, Katsuki didn't speak anything in return, Izuku curiously looked up and Katsuki quickly looked away, unable to spot the mischievous grin on Izuku's face.

"Kacchan is blushing, see anything you like, Kacchan?"

"Don't fuckin' test me, Deku." Katsuki mutters, quickly unwrapping Deku's arms from him. His face was purely red, "have you told your parents you're leaving yet?"

"Oh wait." Izuku quickly turns around, "mom! Dad! I'm leaving!" Izuku quickly says before he closes the door and looks back to Kacchan.

"There, I told them, can we go now?"

"Yeah sure, whatever." Katsuki grunts, walking away, Izuku quickly catches up to him, intertwining their hands together, Katsuki huffs, looking away, his face clearly red.

"Hey Kacchan, do you think I look cute?"

"Sure, Whatever." Izuku pouts.

"Come on, look, I'm wearing your hoodie, isn't that cute?" Izuku asks again.

"It sure fucking is." Izuku pouts, huffing, he tugs his hand off from Katsuki's, crossing his arms and looking away instead. His tail angrily twitching.

"Tch stop acting like a brat, what the shit do you want me to say?!"

"That I look cute."

"I already told you that you looked fucking cute!"

"Hmph."

"Deku!- ugh fine be a fucking brat, we're talking once we get to my house."

_____________________

Izuku wasn't actually that angry. He really just wanted the blonds attention, to be fair it worked, throughout the entire walk and ride, all Katsuki did was try to make up with Izuku ( even if he himself was confused over why Izuku was angry with him in the first place ), of course Izuku ignored him but there were times where he almost couldn't resist how sweet Katsuki was being, like when he bought Izuku a bouquet of flowers and got him a teddy bear and tried to hold his hand.

"Deku, come on- talk to me." Izuku ignores Katsuki in favor of entering his house, where he immediately plopped down the sofa, took out his phone and started scrolling through his feed. He wonders how long until Katsuki gets fed up and slams Izuku into a wall or pin him down or something, doesn't that happen in shounen mangas? Would Katsuki do something like that too?

"H-Hey are you hungry? I have cereal or some shit but I can order something too." Katsuki said, sitting next to him. Izuku huffs, putting down his phone and looking at the blond. He looked really regretful over what he did ( or what he still isn't doing ), Izuku huffs, deciding to take things into his own hands.

"Sure fine, but I want a kiss." Izuku says, Katsuki lets out a sigh of relief, quickly doing the action.

"There, are you happy now?" Izuku shakes his head.

"Come on Kacchan, I ever only wore your hoodie today! Is that all you really want to do to me?"

"Hah?" Katsuki looked confused before his face poofed into red, looking down at the hem of the hoodie Izuku was wearing, he hesitantly lifts it up revealing only pale greyish-green skin and smooth scales on the sides.

"W-What-?!"

"Go! Do perverted things to me already, don't you want to punish me or something?!"

"W-What the fuck?! Deku if you wanted sex then just ask normally!"

"It's embarrassing!"

"But you saying that shit isn't?!" Katsuki groans, his face completely red.

"Don't complain when you're already half-hard!" Izuku whines, "I'm not doing it here on the couch, carry me up your bed Kacchan!"

"Go walk!"

"Please, Daddy?"

"..."

Izuku giggles in delight when Katsuki lifts him up bridal style and starts walking him up his room.

"You manipulative little of shit."

"You love me!"

"And I'm wondering why."

Katsuki kicks his door open, dropping Izuku down the bed hastily, not even bother to close the door, he climbs ontop of the smaller teen and was about to remove his boots when Izuku kicked him.

"Ow- the shit was that for?!" Katsuki groans.

"I look cute in it, don't remove it."

"We're on my bed and you want to wear boots?!"

"Just remove my shorts Kacchan!"

"Shorts- shit you went commando?!"

"Your hoodie is big enough to reach half my thighs, you probably didn't notice." Izuku says, waving the oversized sleeve around, "isn't it a nice surprise?"

"How perverted are you?"

"I don't know what you're talking about."

"Stop being a brat."

"Stop being you."

"Fuck you."

"You'll be doing that soon."

"!!!- F-Fuck you!"

"Stop saying it and just do it, Kacchan-" Izuku was quickly cut off by Katsuki connecting their lips together, letting out a sigh of relief, he quickly wraps his legs around Katsuki's torso, pulling the blond closer, he felt a surge of excitement, feeling fingers reach up the hoodie he was wearing and playing with the hem of his shorts, he lets out a yelp, feeling a smack to his thigh.

"H-Hey!"

"What? Thought you wanted punishment or something." Izuku flushed red, looking away.

"Why the shit are you the one shy when you're the one who suggested it?!"

"S-Shut up!" Izuku mutters, pulling away, "I-I'm removing my shorts."

Katsuki pulls back as well, watching as Izuku quickly remove his shorts, flinging them off the floor.

"Hey Kacchan, do you have lube?" Katsuki nods, pointing at the drawer, Izuku quickly pulls it out, handing it to Katsuki before laying on his stomach and raising his hips up, presenting himself.

"Seriously?"

"As I said Kacchan, don't complain when you're already hard-" Izuku squeaks when Katsuki slaps his ass again, pouting as he turned his head to look at the blond over his shoulder.

"What was that for?!"

"Punishment." Katsuki grunts, climbing ontop of him and shoving his head down the pillow, "don't look and accidentally freeze me, idiot." Katsuki mutters, Izuku nods, his tail curled up excitedly. He let out a gasp, feeling something cold press unto his entrance before it went in.

"You okay?" Katsuki asks.

"Ah geez, you can be rougher, I'm supposed to be punished, you know?" Izuku says, looking back at him.

"Hah? You really want me to?" Izuku nods, burrowing his head to a pillow again, spreading his legs more and raising his hips a little higher, he whimpers, feeling another smack to his thigh before Katsuki starts to roughly thrust his finger inside of him, it kind of stings but it's not that bad, he just kind of wished he didn't choose this position, he wanted to see what Katsuki looked like right now.

"Hey can I-" Katsuki paused, not finishing the sentence before he inserted another one in just as rough as he did to the first, making scissoring motions in Izuku right now, Izuku whimpers when Katsuki hit something inside of him, trying to push the blond to touch it more there, yelping when he's smacked on his thighs again, hugging his pillow tightly as Katsuki roughly tugged on his tail.

"Oi, remember the safeword." Izuku nods, his tail squirming excitedly, Katsuki sighed, continuing to roughly thrust his fingers and spread it inside of Izuku.

"Seriously, If you want me to stop-"

"Ah geez! I know the safeword just be rough with me already!" Izuku pouts, "Seriously, I'll be mad again!"

"Okay okay!" Katsuki huffs, pushing another finger in, Izuku whimpers as Katsuki presses down on his prostate, hitting it with every thrust of his fingers before pulling out. Katsuki was about to ask if he can put it in now but Izuku was already glaring at him, he sighs, rolling the condom on, pouring a generous amount on his dick before gripping Izuku's hips and pulling him to press inside steadily.

"I'm okay I'm okay!" Izuku says even if not asked, gripping the pillows tightly, it's as thick and large as he remembered, but just because he's ready doesn't mean he's actually ready for the real thing, he lets out a whimper as Katsuki filled him in until the hilt, his thighs trembling and he couldn't hold himself up anymore, he doesn't know if Katsuki already noticed or what but he's already hitting his prostate directly!

He lets out a squeak when Katsuki pulled back and thrusted in just as fast, biting his pillow hard, Katsuki paused.

"N-No I'm fine! J-Just keep going!" Izuku quickly reassures, almost regretting it when he lets out a mewl after Katsuki let's him take another rough thrust inside. Clawing at his pillow, he hugs it tight as Katsuki grips his hips tight, pounding into him and shoving him up the headboard, letting out soft whimpers and mewls each time his hips slaps with Katsuki's.

"Oi Deku, you can still back out now if you want." Katsuki says, panting as he keeps up the quick and rough pace, Izuku shakes his head, blinking, confused when Katsuki stops before he's flipped unto his back, he lets out an uncomfortable whine when Katsuki grabs the back of his thighs, practically pushing his knees next to his ears, he felt so exposed right now, his face completely red and he forces his eyes shut, not that he kept it shut, his eyes widened when he felt Katsuki bottom out with a sharp thrust, panting as he watched the dick disappear inside of him before the blond continued on with a punishing rhythm.

His legs were twitching and shaking as he's sprawled out like a rag doll, only having enough strength to cling to the sheets under him as he took everything Katsuki's was giving him.

He woke up on the same bed, already cleaned up and wearing a different hoodie.

"Kacchan?"

"Oh, you're awake." Katsuki mutters, turning off his phone, "you passed out a few minutes ago after you came, are you okay? Geez you should've told me to fucking stop when you couldn't handle it anymore."

"...But Kacchan, it felt really good."

"You passed out for fucksake!" Izuku blinked, looking down and noticing the tent down the blankets, Katsuki flushed.

"I-I'll go to the bathroom-"

"No." Izuku says, throwing off the blanket, "Kacchan, lemme-"

"Oh hell no! You just passed out-"

"Please?"

"...If you pass out again it's not my fault." Izuku let out a happy grin as he leant down, making Katsuki cry out when he practically shoved the thing down his throat.

"H-Hey you'll choke if you do that!" Katsuki mutters, feeling it hit the back of Izuku's throat already, Izuku winced, but determined. Katsuki threw his head back as Izuku started to deep throat his dick, rubbing with his hands what he couldn't reach with his mouth, trying to shove in as much dick as he can down his throat.

Katsuki gripped his hair, gently thrusting up to his warm heat, trying to hold himself back from fucking into his mouth before he released a few minutes later, Izuku tried his best to swallow as much as he can before he choked, pulling away and coughing, letting it hit his face as some dribbled out of his mouth.

"Shit, you okay?" Izuku nods.

"Mhm, Kacchan, do it in my butt next time."

"W-What?! You pervert that's not safe!"

"C'mon we have the entire day for ourselves-"

"Atleast eat first! I'm gonna order some pizza, go clean yourself up or something, I'll take a shower first." Katsuki grunts, tossing him a roll of tissue as he marches into the bathroom, shutting it tight and locking it.

Izuku stares at the door and then the tissues before shrugging. Well Katsuki didn't completely deny him, it should be fine, right?
