late to katsuki’s bday but he can have izuku’s virginity as a gift <3

cw // innocence, some dubcon cause izuku is against sex but katsuki convinces him to agree throughout

deku was spread out under him, the prettiest blush on his cheeks and chest, his thighs clenched +

together, and his arms wrapped around his stomach.

“kacchan, are you sure this will make you happy?” deku asked. “it doesn’t feel like it.”

katsuki snorted. deku had no idea just how happy he was making him right now.

“deku, just lay and there look pretty okay?”

“okay, kacchan,” deku gulped. his chest rose and fell slowly with every breath. he had no clue what was going on.

all he knew was that kacchan had asked him for a birthday gift and nothing more. he did find it a little strange that he was naked while kacchan was not.

he wasn’t scared though. he trusted kacchan with his life, and he knew kacchan would never hurt him.

katsuki gently grabbed deku’s thighs, nudging them open, and draping them across his own hips. deku made a noise of discomfort under him, and his cheeks bloomed a brighter red.

he brought his hands down to his pretty cunt, covering himself from katsuki’s view.

he couldn’t have that.

“deku, move your hands.”

deku shook his head.

“i don’t like you staring,” he whispered. “it’s embarrassing.”

katsuki grabbed his wrists and pinned them beside his head.

“this is normal deku. there’s no need to feel embarrassed.”

“but the church—“

“fuck the church, deku. do you trust me?”

“yes kacchan! with all my heart!”

“then let me do this. you just be a good boy and enjoy yourself.”

deku sighed, defeated, but he nodded anyway.

he could be a good boy for kacchan.

katsuki grinned to himself. he had been waiting to fuck deku for so long, and the opportunity presented itself when deku had told him he could have anything for this birthday.

anything meant anything, and he was going to hold it against deku.

was katsuki taking advantage of deku’s kindness? maybe, but if it got his dick wet he was going to ignore the moral part of his brain.

“deku, want your pussy as my birthday gift,” katsuki groaned, trailing one of his hands up and down deku’s upper body.

he pulled at a nipple curiously, delighted that it immediately hardened. deku moaned quietly, squirming around nervously.

“we can’t kacchan! sex before marriage is a sin, and you know what happens to sinners,” deku said. katsuki lowered his lips to the other nipple.

he sucked and pulled at it, shutting deku up immediately.

“no one’s going to know deku. it’ll be our little secret, alright? a secret that only we know.”

deku frowned, but another pull at his nipples distracted him. katsuki continued to play with deku’s chest, watching deku’s +

body react so deliciously to his ministrations.

“gonna play with your pussy for a bit, deku. is that okay? can i play with your pretty pussy?”

deku shook his head no.

“no sex before marriage, kacchan,” he pouted.

“it’s not sex deku. just some foreplay. there isn’t anything +

in the bible against that, is there?”

“well no, but technically—“

“then there’s no issue, baby. plus, it’s my birthday. don’t you think kacchan deserves a treat on his special day?”

deku turned his face away, but katsuki saw the small nod he gave.

“thank you, darling. +

promise i’ll make you feel so good.”

katsuki pressed a quick kiss to deku’s lips, and then he made himself comfortable. he lay on his front, moving deku’s legs over his shoulders so he was eye level with his cunt.

“with your mouth?” deku squeaked. “that’s dirty, kacchan.”

katsuki ignored him. he would have deku crying in pleasure soon.

“spread your thighs a bit, deku.”

deku obeyed, and katsuki buried his face into the spot in front of him. he hasn’t even started, and already he has deku squealing in pleasure.

he licked a long stripe from +

deku’s hole to his clit, and immediately deku’s thighs clenched around his head.

he could die happily here, worshipping his boyfriend’s pussy.

he lapped gently at deku’s clit, letting him adjust to the foreign feeling. deku moaned and whined above him. his entire body was +

shaking already, and katsuki relished in the feeling.

he unzipped his pants and took his cock out, already hard and leaking. he gave deku no warning.

he ate deku out like there was no tomorrow and jerked himself off. he bit and sucked on deku’s clit, fucked his tongue into +

his hole roughly. he was messy with it too. he had drool and slick on his chin, and fuck did deku taste good against his tongue.

deku keened and mewled and thrashed around, his thighs crushing katsuki’s head as his whole body twitched in pleasure and already overstimulation.

katsuki had never been so painfully hard and so fucking close to coming.

a particular thrust of his tongue had deku arching his back. katsuki looked up at him, loved the tears streaming down his face.

“kacchan, feels funny down there! feels like—feels like i’m imma pee. +

kacchan, stop—stop—“

deku fucking squirted, and katsuki almost came. it was the last thing he expected, but it was so incredibly hot.

he surged forward, grabbing deku’s hips, and slotting his dick between deku’s folds.

“deku, darling, let me fuck you, please,” he pleaded.

“kacchan, we can’t! we’re not married! we could go to hell—“

“just the tip, deku. at least just the tip,” he whispered. “i’ll pull out before i cum, promise.”

deku looked torn. he just needed a little push.

“this is what i want for my birthday, izuku. it’ll make me so happy +

if you let me do this.”

“just the tip?” deku looked at him so sweetly, so trusting. katsuki nodded, and deku spread his legs for him, willingly.

katsuki watched in amazement as deku’s hands trailed down his body and spread his pussy lips for him.

“i trust you kacchan.”

katsuki willed himself to calm down. he guided his cock inside, pushing in as slow as possible. deku whimpered in pain, and katsuki kissed him, hopefully distracting him.

deku was so hot and tight and wet around him. his walls squeezed rhythmically around his cock. +

he pulled back, cock leaving deku’s pussy, and then he pushed back in again. he did it a few times to get deku used to it.

once deku’s hips started to move on their own, katsuki took it as a green light.

he thrust forward, shoving his cock inside. they both moaned, and soon +

their sounds of pleasure began to fill the room. katsuki thrust in and out quickly, already close to coming.

tweet limit so tbc quickly

he stared down at deku. deku with his head thrown back, his eyes squeezed shut. he was too far gone into his own pleasure that he didn’t notice the way katsuki shoved another inch of his cock every other few thrusts.

he was oblivious, and soon katsuki had his entire cock inside of deku’s cunt.

“gonna come soon, deku,” katsuki groaned.

“not inside!”

“of course, baby. you know i’d never lie to you.”

deku nodded, and katsuki grabbed his hip and slammed him forward. he groaned as came +

deep inside deku’s pussy, kissing deku to distract him. he played with his clit a bit, and deku was coming around him again, cunt squeezing nicely around katsuki.

deku broke away, eyebrows furrowed.

“kacchan, i feel full.”

katsuki watched as deku brought his eyes to +

where they were joined.

he watched as the cloudy haze in his eyes turned into horror.

“kacchan!” deku screeched. he pushed him off, scrambling to sit up.

“you came inside,” he whispered in disbelief. “oh god, you /came/ in /me/.”

katsuki immediately went to hug him.

“i’m sorry, izuku. but you felt so good, your pussy felt so fucking good that i couldn’t help myself. don’t be mad at me.”

deku sniffled, but he returned the hug.

katsuki continued.

“plus, it is my birthday, and you said i could have anything. you wouldn’t want me to be +

unhappy on my birthday, right?”

izuku shook his head. upsetting kacchan was the last thing he wanted.

“still, i trusted you,” izuku repeated. it was quiet for a moment before he spoke again.

“did you feel good kacchan? was it a nice present for you?”

kacchan kissed him, and izuku melted into the kiss, into his embrace.

“the best darling. i promise it won’t happen again.”

katsuki absolutely does it again and again and again. but izuku can’t help but forgive him every time cause he loves him too much <3
