Bunny Boy

Summary:

Izuku huffed and sniffled, large hare ears twitching and flicking, bunny heart beating a mile a second. His little nose twitched and wiggled, dust and smoke filling his flaring nostrils, making him whine and cough.

Izuku whined softly, hare feet thumping against the ground. He was holed up behind some trash cans, clutching his bag tight against his chest, eyes darting around the alleyway every few seconds when another loud bang echoes through the narrow alleyway.

The sounds come closer and closer until the trashcan he was hiding behind is roughly kicked away, a large shadow looming over him. Izuku freezes up, feeling lightheaded as he looks up, coming face-to-face with a pro hero.

"Heh, knew you were hiding here, kid. Alright, kid, let's go,"

"I-I'm good, thanks...I'd rather just go home,"

Katsuki could only stare, eyes looking at the fluffy bunny tail wiggling, poking out of a small hole in the boy's pants.

He knew he was breaking hero protocol but fuck, that defiance made his pants tight.

He needed to see the teen again. Needed to see that fluffy bunny tail bounce. Fuck, needed to see those thighs bounce the bunny up and down on his cock.

Work Text:

Izuku huffed and sniffled, large hare ears twitching and flicking, bunny heart beating a mile a second. His little nose twitched and wiggled, dust and smoke filling his flaring nostrils, making him whine and cough. The petite teen huffed and sneezed, disturbing the still dust around him. He was currently hiding in an alleyway, having scampered to safety, when a villain attack had started.

That was three hours ago.

His mom was going to be soo worried.

Izuku whined softly, hare feet thumping against the ground, anxious and afraid. He was huddled up behind some trash cans, clutching his bag tight against his chest, eyes darting around the alleyway every few seconds, when another loud bang echoes through the narrow alleyway, bouncing off the walls. Izuku's prey instincts that come with his quirk are on high alert, thighs tensing with each loud sound, his prey heart jumping in his chest at everything. His heart nearly jumps out of his chest at the sound of boots crunching on debris echoing in the alleyway, making Izuku's sharp claws scrabble against the dirtied concrete, ready to either attack or flee. He stays stock-still, bunny nose twitching and flaring with each quiet, quick breath Izuku takes. The sounds come closer and closer until the trashcan he was hiding behind is roughly kicked away, a large shadow looming over him. Izuku freezes up, feeling lightheaded as he looks up, coming face-to-face with a pro hero.

"Heh, knew you were hiding here, kid," Katsuki grunts, crouching down. He swore he had seen someone scamper into the alleyway the second the attack started. Fuck everyone else who told him he was seeing shit. Fuckin' assholes. Katsuki huffs as he settles a large hand on the teen's head, huffing. The teen squeaks at the touch, bunny nose twitching and snuffling. Katsuki huffs as he ruffles those soft-looking curls, "Alright, kid, let's go. Coast is finally fuckin' clear," Katsuki grumbles, but the kid stays still, eyeing him with a weary look in those big doe eyes.

"I-I'm good, thanks...I'd rather just go home," The teen says, standing up on big, thumping feet, standing on the tips of his paws. "Hah?!" Katsuki barks, watching those big ears twitch. "The fuck? You think I'm gonna let your puny ass leave without at least having you checked over?" Katsuki snaps at the teen, whose cheeks puff up. "I'm fine! And I'm not a kid!" The teen stamps his foot, the thump sending a few old cans around them rattling as the vibration makes them rattle.

Katsuki raises an eyebrow as those defiant jade eyes glare at him, a buzzing warmth filling his veins, a dark grin trying to etch itself on his face. Katsuki stared at the teen, who tried not to look like he was letting his eyes rove around the large pro hero's body, but Katsuki didn't try and stop him. The teen finally, after a tense minute of silence from both him and Katsuki, puffed his cheeks up, turning on his heel. "I'm going. Don't try to follow me," Katsuki huffed at the weak glare the boy sent him, watching the boy bound off, eyes looking at the fluffy bunny tail wiggling, poking out of a small hole in the boy's pants.

He knew he was breaking hero protocol, but fuck, that defiance made his pants tight. The blond huffed, running a hand through his hair at the dark, lustful thoughts filling his head, making his cock twitch in his pants.

Fuck.

He needed to see the teen again. Needed to see that fluffy bunny tail bounce. Fuck, needed to see those thighs bounce the bunny up and down on his cock.

Katsuki huffed, fisting himself quickly, splattering cum on the spot he found the bunny boy. After a minute of cooling down, his blood pumping so quick that it nearly made him lightheaded. He quickly shoved his half-hard cock into his pants, huffing as he shoved the trashcan back into place.

Fuck, fuck, fuck...

He needed to find that bunny boy.

-

It took a few weeks. Nearly seven weeks, but fuck, he found him again. And, fuck. Seeing that fluffy green tail bounce as the boy took steady steps, watching those large, pretty ears twitch and rove around. Watching that little bunny nose twitch.

Fuck, it made his pants tight. Thank god he was wearing baggy sweats.

The boy was at fucking U.A., of all things. General course, but at fucking U.A. And fuck, Katsuki watched from the stands around U.A. track as the bunny ran at impressive speeds, quick feet propelling him forward. The boy's fat, bubbly ass was nearly sinful in those thin, tight track shorts. Watching that fat ass jiggle and bounce with each bound was making Katsuki's knees weak, and he was sitting down, for fucks sake.

Katsuki glowered at that pretty ass jiggling, not even realizing the bunny boy was walking over to him till he was in his face, staring into those beautiful deep jade eyes, making Katsuki nearly startle back. But he kept his eyes locked with those deep jade eyes, keen ears hearing the bunny boy heave softly, having run for miles, and that was only when Katsuki was watching him. He was already running when Katsuki got here.

"What are you doing, Mr. hero? Ogling at students," The bunny boy grinned as Katsuki glared. "Don't think I've seen you staring at me either, bunny. You're not so innocent either," Katsuki sniped back, watching that bunny nose twitch in irritation. "Oh? Lil ol' me?" The bunny boy's once narrow eyes widened into those pretty doe eyes he had seen that fateful day. Fuck, those beautiful eyes make his cock twitch. "I can't be anything but innocent, mister. I have no clue what you're talking about," The bunny boy gets closer, twitching, soft bunny nose brushing against him. The bunny boy's hands are planted on his knees, squeezing softly. Katsuki's eyes are dark with lust, staring at the bunny boy, whose a fucking tease.

Fucking brat.

Katsuki's hands, once hanging limply on his sides, gripped the bunny boy's hips, pulling the boy into his lap, making him squeak. That high-pitched, chittering squeak turned into a moan as the bunny boy was squished against his hard cock, twitching as he felt a smoldering heat press against his cock. Katsuki watched as the bunny boy's face crumpled into a soft moan, hips bucking against his cock. Katsuki could feel that fluffy tail swishing, the longer tufts of fur tickling his large hands that practically enveloped the bunny's hips. Those thick thighs twitched as the bunny boy bucked and rut against his hard cock, face a dark red.

"Heh, knew you were a useless slut," Katsuki huffed, pulling the bunny up till he could shove those tight, sinful track shorts down and off bunny boy, till they crumpled on the ground in a small pile. Katsuki huffed as he lowered the bunny, licking his lips at his bunny boy had gone fucking commando. "No panties? Heh, were you hoping someone would find you, running around in these short-ass track shorts, rip them apart and fuck you into the ground?" Katsuki growled, running a finger up and down bunny boy's slit, feeling the liquid heat drool into his hand. Bunny boy whimpered, bucking into his hand, face a dark red. "S-Shut up..." The bunny boy whimpered, bucking into his hands as he rubbed that chubby clit poking through those puffy lips.

"Nah, 'm good," Katsuki laughed as he groped bunny boy's ass, stroking the teen's tail, feeling it wiggle and shiver under his touch. Katsuki slipped two fingers into that tight, wet heat, licking his lips as bunny boy twitched and writhed in his hold. "Hm, so tight, bunny," Katsuki huffed, slowly fingering Izuku open, feeling around for that chubby g-spot. Katsuki's heel ground against the teen's clit, making him huff and whine, head flopping onto his shoulder. "Ah, found it," Katsuki pressed against the teen's g-spot, making him shake and writhe in his grasp, gasping and bucking into his hand. "A-Ah...! F-Fuck," Bunny boy whimpered into his neck, tail shaking and quivering with pleasure. Katsuki's hand, gripping and groping the teen's ass, came down with a hard thwack! against that supple, freckled asscheek. "A-Ah?!"

Bunny boy squeaked, pulling back to look at him in bewilderment, flushed face debauched. "No swearing, brat," Katsuki huffed, speeding up his thrusting fingers, watching the teen slowly fall apart. "A-Ah...haaa..." The teen whined out, face scrunching up as he bucked hard against Katsuki's thrusting fingers. "G-G'nna...c-cuumm...!" The teen slurred, mouth popping open as that cute little tongue lolled out, pretty jade eyes sliding up into his head, choking a gurgled, cracked scream as he came. Katsuki grasped the teen's nape, pulling him down till their lips connected in a sloppy, lustful kiss, allowing Katsuki to swallow the boy's whimpers and moans. Katsuki's fingers didn't slow down, speeding up as he brought the teen into another bone-shaking orgasm, watching squirt drip and splash onto the bleachers below them.

"T-Too much...!" Bunny boy squeaked, trying to raise his hips, but Katsuki's fingers chased that tight, warm cunt. "Hah? Too bad," Katsuki grumbled but eventually pulled away when Bunny boy started to sob, watching slick and squirt drool off his fingers. The smell was pure lust and tasted like sticky ambrosia on his tongue. Katsuki swirled his tongue around his fingers, lapping up that sweet-tasting slick, watching bunny boy flush and twitch in his lap, cunt a cherry red. "Fuck," Katsuki huffed, freeing his cock, watching the tip of his cock squish and rub against the boy's chubby lips.

"Wanna fuck you so bad. See how hard you got me, baby?" Katsuki growled, rutting against the teen's pussy, watching the tip of his cock disappear between those puffy lips, feeling the heat rolling off the teen's pussy. "Want me to stuff you full? Fuck you till you can't walk?"Katsuki cooed, watching the teen crumble, whing and nodding quickly. "Hmm, but first, baby," Katsuki's hand snuck under that soft tanktop, fondling the teen's chubby nipples, rolling them between his fingers. "Gotta make sure I'm praising the right name, baby," Katsuki pats the bunny boy's thigh, watching those hazy jade eyes try to focus on him. "Izuu..I-Izuku," Izuku slurs, tongue heavy in his mouth, almost as heavy as the heavy cock pressing against his fluttering hole, clit twitching against that thick, veined shaft.

"Hmm, good boy, Izuku," Katsuki purrs as he angles his hips, tip popping in before he slams in. "Nhaaahgn!" Izuku shouts as he cums, sobbing as he bucks into the large blond, allowing that thick cock to slip deeper before he's flush with Izuku's cunt. "F-Fuck, so tight, baby," Katsuki groans, leaning back till his back is pressing into the next level of bleachers, uncomfortable, but the tight heat enveloping his cock is more important. "So, fucking, good!" Katsuki growls, gathering his footing as he thrusts with each word he speaks, balls slapping against that bubbly butt, the loud claps echoing in the practically abandoned track. He's never seen anyone in his time in U.A. use this track.

Katsuki growls as he feels Izuku's cunt flutter around him, gripping those thighs tight as he slams up into Izuku's cunt, thighs flexing with the strain. His back ached, but he didn't give a shit, keeping a hard, fast thrusting pace, his heavy balls slapping against Izuku's ass. "Fuuuck," Katsuki hissed, feeling the coil in his gut tighten with each heavy thrust. "Gonna fucking...fill you...Fuck you full of my cum, baby," Katsuki growled, feeling his mouth pop open as the coil in his gut snapped, burying his cock hilt-deep in Izuku's fluttering pussy, watching Izuku fall apart as the first spurt of virile cum painted his walls white. Izuku rutted his hips back and forth, cumming for the last time before flopping forward.

Fuck, he's fucked.

Katsuki's cock pops out as cum drools from Izuku's gaped pussy. The two lay there, panting in the afterglow. "So good, baby," Katsuki huffs. "S'good,"

Fuck.
