Work Text:

“Zuku?” Katsuki called as he opened the door of their dorm room. Hearing no response, Katsuki closed the door behind him silently and placed the groceries he had bought on their small kitchen counter. 

 

Katsuki quietly walked towards the middle of the room, towards Izuku’s bed. There lay his childhood friend, hidden under a thick All Might comforter with only her eyes and nose visible. His little bunny burrowed under the softest sheets that Katsuki had bought for him for Christmas.

 

Katsuki smiled softly, pushing Izuku’s curls out of her face, then caressing her cheek ever so softly. “Zuku…” He whispered, tracing Izuku’s lip with his thumb. 

 

Fucking hell… 

 

Izuku hummed, stirring in his sleep. “Zuku bear?” Katsuki called again, leaning down to kiss Izuku’s cheek, forehead, then the tip of his nose, making Izuku scrunch. “Hmmm…Kacchan…?” He whispered, slowly waking up from his nap.

 

“Hi Zuku bear…What do you want for dinner?” Katsuki asked in a hushed voice, “Katsudon…” Izuku murmured, snuggling closer into Katsuki’s hand, kissing his palm. 

 

Katsuki’s breath hitched. His Poor little bunny did not know how crazy he made Katsuki. Innocently mirroring Katsuki’s treatment and innocently doing everything a roommate should not let their other roommate do.

 

“Zuku, Kacchan needs his payment, sweetheart…” Katsuki bent down, whispering into Izuku’s ear, making the other boy shiver, “‘Kay ‘Kay, Kacchan.” The sleepy boy replied. 

 

Grinning devilishly, Katsuki pulled away, moving towards the end of the bed to lift Izuku’s comforter out of the way. Izuku, being the innocent little bunny that he was, has never ever let his boyfriend, Shindo, touch him on his “no no” spot, only ‘Kaachan’ because that was what roomies do. But Shindo thinks it's just because Izuku was a virgin. He thinks.

 

As Katsuki moved the comforter out of the way, he was met with Izuku’s milky white, thick thighs littered with freckles, his mouth filled with saliva at the sight of his little bunny. 

 

Licking his lips, he moved the comforter further away, revealing Izuku’s booty shorts. Katsuki bites his lip as he moves Izuku’s shorts to the side.

 

Best fucking payment.

 

There, laid out for Katsuki, was Izuku’s little glistening hole, ready to be devoured by Katsuki. Izuku’s slit, tight as it was, was now gaping from the frequency of Katsuki taking his “payment”. His once tight hole was now slightly gaping, never closing, slick, dripping down further to Izuku’s perineum when Katsuki blew on it a little.

 

“Itadakimasu ~”

Katsuki dived down, sticking his tongue out, forming an eight on Izuku’s pussy. From his clit to his pussy lips down to his gaping little hole, Katsuki lapped and lapped at the dripping slick that gushed from Izuku’s fuck hole. 

 

Whimpers were fucked out of the sleeping boy as his pussy was assaulted. Katsuki seldom pulls away from Izuku’s pussy to leave small marks along the insides of his thighs. 

 

Placing a small mark near his pussy, Katsuki grinned at his work, fully knowing that if Shindo tried fucking Izuku, he’s going to see the marks Katsuki left behind – As if Shindo would ever get the chance to fuck his bunny. The pretty little thing didn’t even know he was doing something he shouldn’t do; he just knew that ‘Kacchan just loves me, you know?’ the poor little thing constantly said. 

 

Sad little Shindo thought he could take Katsuki’s hard-earned place in Izuku’s life, no fucking way. 

 

Katsuki returned with an onslaught pace on Izuku’s clitty, sucking, nipping, and flicking his tongue on the bundle of nerves. Izuku was moaning louder now, “Kaachan…’ Zuku’s ‘gon pee!” The boy squeeled, now fully awake from his slumber. 

 

Katsuki just hummed in reply, pushing his face deeper into Izuku’s pussy. Moving his hand away from Izuku’s thighs, Katsuki circled his forefinger outside Izuku’s fuck hole. Pushing in slightly but not curling it up, then out again, then in, at a grueling pace, making Izuku groan in frustration.

 

“Kacchan! Feels weird!” His Bunny whimpers. Katsuki smiles against Izuku’s pussy lips, continuing his abuse. 

 

“Kacchan, please…” Izuku moaned out as Katsuki curled his finger up slightly, but not enough to make Izuku cum. Katsuki pulled away from Izuku’s pussy and sat up. 

 

“Kacchan no!” Izuku cried at the loss of Katsuki’s mouth on his pretty pink pussy.  “Shh…Pretty baby…” Katsuki shushed his fussing bunny. 

 

“Whose pussy is this, baby girl?” Katsuki asked, slowly pumping his fingers in and out of Izuku’s hole, curling it a bit but not enough to stimulate Izuku to orgasm – edging him. 

 

“Kacchan’s!” Izuku moaned out, making Katsuki grin. The blonde placed his other hand on Izuku’s abdomen, pushing down as he finger-fucked Izuku. Izuku screamed, legs shaking as Katsuki hit his g-spot over and over again, “Kacchan! ‘Gon cum!” He screamed, “Gonna cum for me, my bunny?” Katsuki instigated, fucking Izuku faster, “Yesh!” 

 

Katsuki stopped, his fingers unmoving inside Izuku, making him sob. “K-Kacchan, meanie!” He sobbed, gyrating his hips, trying to urge Katsuki to fuck him. 

 

Katsuki leaned down, “Does Shindo get to touch your pretty pussy, ‘Zuku?” He whispered into Izuku’s ear, “N-no, o-only Kacchan!” Izuku cried, still trying to fuck himself onto Katsuki’s finger.

 

Pitying his bunny, Katsuki moved his fingers slowly in and out of the boy. “Yeah? Why is that, ‘Zuku?” He hummed, licking the shell of Izuku’s ear, making the small boy shiver. Katsuki traced the shell of Izuku’s ear with his tongue, kissing it softly, making small moaning sounds right into Izuku’s ear canal. 

 

Izuku moaned so loud, shivering from Katsuki’s abuse. “Kacchan only…No more Shino…” Izuku whimpered. Katsuki, not satisfied with Izuku’s answer, continued his abuse of Izuku’s ear. Nipping, licking, kissing, and moaning into his ear. 

 

Soon enough, Izuku was clamping down tightly on his fingers. His fucking slut came on his fingers just because he was licking the little fuck bunny’s ear. 

 

Angered by Izuku cumming without permission, Katsuki ripped his fingers away from Izuku’s fuck hole and flipped Izuku over.

 

“Fucking bunny cumming on my fingers, not giving me the right answers, how the fuck is this paying me back exactly, Izuku~” Katsuki growled into Izuku’s ear, pinning him down. 

 

“Kacchan…You’re scaring me…” Izuku cried, “I-I’m sorry, Kacchan,” He sobbed. Katsuki just grinned evilly, pushing Izuku’s booty shorts fully down now, and pulling his rock-hard cock out of his sweatpants, one hand holding Izuku’s hands in place on his lower back. 

 

“Why the fuck is Shindo not allowed to see your little pussy now, Izuku?” Katsuki asked in a commanding tone, “‘Z-Zuku broke up with Shindo.” The boy sobbed. Making Katsuki cackle as he rubbed the mushroom tip on Izuku’s sopping wet pussy. 

 

“Yeah? You did?” Katsuki mocked, making Izuku sob harder as Katsuki pushed his cock slightly into Izuku’s pussy, then out, never fucking any further than that. 

 

“H-He said either h-him or K-Kacchan…’ Zuku chose Kacchan…” Izuku cried harder. Katsuki laughed. Without warning, he inserted his cock fully into Izuku’s warm fuck hole. 

 

The smaller boy cried out, moaning so loudly that Katsuki’s pretty sure his neighbor would complain again later. 

 

Izuku tried pulling away from Katsuki, his little hands opening and closing, desperately trying to grab onto something. Katsuki set an incredibly fast pace, fucking and fucking into Izuku. 

 

“M’gonna cum in you, my sweetness, yeah?” Katsuki grunted, finally fucking into Izuku’s hole. God knows he has waited so long to fuck Izuku. He didn’t even ask Izuku to break up with the little wuss, Shindo You; Izuku chose him. 

 

Katsuki planned to fuck his roommate next week, but fucking hell, today’s the fucking day, little ‘Zuku’s gonna get his virginity taken, and get pregnant. 

 

“Y-yesh…” Izuku replied, Katsuki grinned, flipping Izuku over and forcefully kissing him. Izuku’s face was fucked out, his pert tongue hanging out, eyes crossed and red with tears dripping down from it. Truly fucked out. 

 

“Do you even know what that means, Deku?” Katsuki insulted the sobbing, moaning, ditzy boy, “N-no…Trust Kacchan.” He moaned out, so far into his own pleasure that he didn’t even know he was going to be made into a mommy by tonight. 

 

Katsuki grinned, pulling away from Izuku’s face, placing one hand back onto the boy’s abdomen, and the other choked the freckled boy. 

 

Izuku’s eyes shot up at the pace Katsuki placed again, fucking in and out of him, hitting his cervix, hitting everything inside of him. Izuku’s hand flew up to grip the hand Katsuki had on his throat, mouth opening.

 

Without any warning, Katsuki’s lower half was soaked. Izuku fucking squirted on him, making Katsuki laugh, “My sweet fuck toy, I’m gonna make you a mommy!” Katsuki shouted, but Izuku couldn't care less. 

 

His legs were shaking, his hole clamping so tight around Katsuki’s thick cock, tongue dangling out, drool dripping out of his mouth, brain fried from his ongoing orgasm. 

 

With one last thrust, Katsuki moaned so loud, feeling Izuku’s cervix opening up for him on the tip of his cock, effectively fertilizing the boy’s egg. Katsuki flooded Izuku’s uterus with so much cum, making his once flat abdomen look a little bloated. 

 

“Get pregnant, bitch!” He moaned out, Izuku sighed, feeling Katsuki’s spend warm his insides. 

 

When Katsuki pulled out, his cum dribbled out of the gaping hole. Izuku’s All Might sheets were stained with his own slick and cum mixed with Katsuki’s semen. 

 

Perfect.

 

A few months have passed, and Izuku lay there, cross-eyed, his, well, Katsuki’s shirt pushed up, revealing his perky tits exposed, neck littered with hickies, bite marks littered his body, his pussy all open and red with so much cum dripping out of it, and his once flat stomach was now a little fuller, a little rounder. 

 

“Zuku, smile!” Katsuki said, Izuku, still dazed from how much he had cum, smiled at the camera, throwing up peace signs. He sends the picture to himself and saves it on his phone in an album titled “My Little Fuck Bunny ♡” . 

 

Katsuki placed their phones back on the bedside table, grabbed Izuku’s panties from the floor, and slipping it on the still dazed boy. Not even bothering to clean Izuku up because the last time he did, the bunny stomped, saying, Kacchan does not want me anymore! No more mommy ‘Zuku!” and that’s when they found out that little Izuku was two months pregnant. 

 

A notification pinged from Izuku’s phone, making Katsuki reach for the device again. He chuckled as he unlocked the phone and scrolled through the notifications they had ignored for three hours, along with the new ones.

 

Shindo You Senpai

 

: Izuku, please. I won’t make you choose between us again, please.



Katsuki laughed maniacally, sending the photo to Shindo.

 

Awe : 

You won’t get invited to the baby shower btw. : 

 

 

: Fuck You, Katsuki. You, corrupted fuck.



Being the petty man that he is, Katsuki pulled Izuku’s panties down again and pressed down on the boy’s abdomen, making more cum spill out of him. 

 

Pressing the record button, “Zuku, do you like being a mommy?” He asked, Izuku smiled dreamily, his small hand travelling down his pussy, circling and playing with the dripping cum out of him. 

 

“Yes, Kacchan…” He hummed, “Who’s the daddy, baby?” Katsuki asked, giggling behind the camera.

 

Izuku was now fingering himself open, showing the camera his dripping pussy. He had been trained by Katsuki to be so slutty in front of the camera because he thinks that ‘Kacchan needs this because it makes him happy.’ 

 

“Kacchan’s daddy!” He moaned out, curling his finger inside of his gaping hole, pulling it out and showing the camera as he scooped some of the cum out, placing some of the scooped-out cum into his mouth, and sucking his fingers while making eye contact with the camera. 

 

Ending the recording, Katsuki quickly sent the video to Shindo.

 

Cry about it. : 

 

Katsuki threw the phone back onto the nightstand, pumping his growing dick and fucking into Izuku.
