Summary: After Deku once again to defy his status as a quirkless nobody, Katsuki decides to put him firmly in his place

-

The stench of the boys’ locker room bathroom was so foul, it could threaten those with even the strongest of stomachs. How badly it smelled was a regularly complained about theme amongst the hordes of boys who were forced to use it every day after gym. Even Katsuki couldn’t stand it and would often wait until they were heading back to the classroom to use the one down the hall, which still smelled bad – as most school bathrooms did – but not nearly as bad as this one. He doubted that this one went without a good scrub for too long but even the strongest bleach couldn’t completely wipe out the odor of dozens of young boys, some of whose quirks produced a noxious smell that sunk into everything. Not exactly the place for a sexual encounter but this…this wasn’t supposed to be a romantic encounter. No, this…this was the exact opposite. What would be a good way to describe this? Katsuki slowly cocked his head, a tight smirk tugging at the corners of his lips.

He supposed the best way to describe it was…breaking in a new pair of shoes. Had to rough ‘em up a little bit before they fit just right. For something like that, this was the perfect place. It smelled like crap, piss and weeks old sweat. Toilet paper littered the floor and there was a concerningly dark gunk growing around the edges of the walls, floor and ceiling. He had originally thought about doing this in the safety of his bedroom but no, this…this was the right place. This was the perfect place to pound the fact that Deku’s only place was underneath the heel of his foot into the very matter of his being. This was the only place he was worthy of – a disgusting bathroom that could taken away at any moment and not missed in the slightest.

He chuckled huskily, wiping sweat off his brow. His hand came away glistening in the stark white light of the large bathroom. The only noise was the loud, wet squelches of his dick rapidly sliding in and out of Deku’s previously virgin hole and the lewd moans, sobs and whimpers pouring out of the nerd’s stupidly gawking mouth. His round, freckled face was flushed bright red underneath an unkempt mess of sweaty hair. Dazed green eyes, swimming with shameful heat and pained lust, gazed unfocusedly up at him. Deku’s small hands lay loosely clenched on his chest, tightly bound around his thin wrists. The front of his shirt was ripped open, revealing smooth, pale skin that was entirely devoid of scars and blemishes. His pants lay in a crumpled heap a few feet away, along with his shoes and socks.

It had been a bitch to get the nerd undressed when he was struggling and crying, begging him to stop. A threat to blow off his head with a well-aimed blast had been enough to get the scum to be quiet…up until the point he was about to put it in. Katsuki glanced down at his arms. The dark red scratches that Deku’s blunt nails had made still stood out prominently. He hadn’t expected the nerd to fight back that much. A weakling like him…he should’ve realized that he stood no chance against him. Still, the bastard had the audacity to try to escape. The corner of Katsuki’s lips twitched. He clamped his hands down tighter onto Deku’s thin, trembling hips, shifting the position of his thrusts to slam the head of his cock against the nerd’s prostate. Letting out a shrill squeal, Deku threw his head back. His eyes widened even further. A violent tremble shook his small body. A spurt of precum spilled out of his twitching cock, splattering around his belly to mix with the mess of jizz already coating his flushed skin. The inner walls of his ass clamped down even tighter around him, creating a narrow tunnel that sucked and squeezed as he pushed in deep. An intense burst of pleasure cascaded out from the base of his belly, sizzling through his nerves.

“N-No! K-Kacchan! Kacchan-! Stop-! Stop-! My head-! My head feels funny-! I don’t wanna-! I DON’T WANNA CUM ANYMORE!! PLEASE-!!” Deku wailed miserably, frantically shaking his head. His chest heaved with shallow, ragged breaths. Reaching forward with visibly trembling hands, he grabbed and clawed at the front of Katsuki’s shirt. After a couple fumbles, he managed to get his fingers curled into the thin, sweat drenched fabric, weakly tugging on it. Looking up at him pleading, Deku gasped, “Please-! Please-!”

“Shut it. You really gonna say stupid shit like that when your slutty hole is sucking on me this eagerly?” Katsuki laughed huskily, slamming his hips against the stupid nerd with enough force to make him jolt upwards. A rush of electric pleasure rolled through him like a shockwave, igniting fireworks of tingles that cascaded across his skin. Harsh pants pushed between his clenched teeth. Blood roared in his ears. Fuck…fuck! Being inside this pathetic nerd felt so fucking good-! He was so hot! So tight-! Deku cried out shrilly, his eyes bulging then tightly squeezed shut. He choked out some incoherent gibberish that sounded vaguely like a plea but whatever it was he was trying to say was overwhelmed by a piercing, gurgling wail. Pale, watery cum spilled from his swollen, twitching cock, creating a pool on his lower belly.

Katsuki barked out a cruel laugh. One of his large hands flew up to clamp down onto Deku’s thin jaw, yanking his head up so he was forced to look at him. Mouth hanging open, a dizzy haze clouding his big green eyes, Deku shivered as he leaned in close. The tips of their noses bumped together. Deku’s hot breath washed across his skin. Gross – just like the rest of him. The only good thing about this nerd was this incredible hole. If he didn’t have that, he might as well just disappear. Well…in a way, he was going to. Once he was done with him, this disgusting idea that he so desperately clung to that he was going to be a Hero, that he actually had some worth beyond being a toy would vanish – crushed underneath the immense weight of a newly developed addiction to his cock.

Slowly rolling his hips to grind against the sweet spot inside of Deku’s hole, Katsuki rasped, “How many times does that make it, shitty nerd? Gotta be five times now that you’ve cum while being raped. Fives times…” he let his voice trail off, the corners of his lips curling up into a cold smirk. He reached down to wrap his other hand around Deku’s burning hot, sopping wet length. He shrieked shrilly, his hips violently bucking to drive his cock through the tight ring of his fingers. Deku’s wide eyes crossed, rolling back into his head until nearly only the whites were visible. The color in his cheeks deepened even further, becoming His tongue lolled outside of his mouth, adding an even more sordid note to his already disgustingly messy expression. A wild burst of throbbing, thrumming heat rolled out from the pit of his crotch up to his belly then further to his chest, where it beat against his ribcage. Fuck…fuck! This damned nerd was so goddamn sexy…!

“Five times…and you’re still rock hard.” Katsuki cooed, rubbing the pad of his thumb against the weeping slit, “This body isn’t suited to be a Pro. How could a lewd slut like you hope to save anyone? What’re you gonna do, wiggle this fat ass,” he reared one hand back, bringing it sailing down onto the plump curve of Deku’s backside, wrenching a strained squeal out of him, “and spread your legs so you can fuck the evil out of them?”

“PLEASH!! PLEASH!! STOP! STOP-! KA-! KAACCAAAHNNN!!” Deku howled, though his body, his face actively betrayed those desperate, dishonest words. Panting raggedly, round face flushed a worrying shade of dark red, Deku shakily bucked his hips, obviously trying to match his rough thrusts. Unrestrained lust danced in his teary eyes. Before…there had still been some fight, some resistance, a lingering spark of anger and grief that he was being used, pinned down and forcibly shown just how weak he was but now…For the first time since he started this little training session, a genuinely delighted smile spread across his burning hot face. This wasn’t taking anywhere near as much effort as he thought it would…what a shock. He should’ve known that some as pathetic as this nerd would break almost right away.

“Stop?” Katsuki laughed, rapidly stroking Deku’s twitching length, hungrily devouring every anguished tremble and gasped, “Stop? You really gonna try to lie straight to my face, you stupid fuck?” Lunging down, he brought his face close to Deku’s, his gaze greedily roaming over his tear, snot and saliva caked cheeks. He gleefully chomped down on the plump curve, digging his teeth into the warm, smooth flesh. Deku whined and trembled, his cock twitching in his hold. Dragging his tongue through the mess of fluids, a shaft of heat radiating out from the base of his belly, he rasped, “You aren’t fooling me. This is a whore body – designed to do nothing but take cock and you…you are gonna spend the rest of your life using this slutty hole, this worthless piece of crap whore body to make me feel good.”

Katsuki paused for a moment then asked on a harsh exhale, “Do you understand, Deku? You’re my toy. My plaything. My cocksleeve. My personal toilet. You exist to only take my cock, whether its here,” Katsuki brushed the tips of his fingers across his stuffed full hole, “or here,” he lifted his hand to stroke the pad of his thumb along his plump lower lip, “and you’ll beg for it. Every day, every second, you’ll follow behind me, staring at my back, clinging to me, pleading, begging for me to fuck you.”

“N-No…!” Deku gasped weakly, even as he was shaking with excitement. “Ka…Kacchan…!”

Lips curling into a snarl, Katsuki rapidly ramped up the pace of his thrusts, brutally slamming deep into Deku’s wet, sloppy hole. Shrieking at the top of his lungs, a delirious grin spreading across his even messier face, Deku scrambled to grab hold of the front of his shirt, holding on for dear life as Katsuki quickly dragged him to orgasm number 6. Clenching his teeth together in a grotesque grin, Deku threw his head back, his cock spasming violently. This time, though, nothing came out, besides a weak spurt of fluid that might’ve been thick water. Laughing coldly, Katsuki dipped down to once again bite on Deku’s chubby cheek. When he pulled away, there were visible marks in his flushed skin. The sight abruptly wrenched him right up onto the edge of cumming.

Choking out a ragged groan, Katsuki stepped back, sliding his sopping wet, throbbing cock out of Deku’s slutty hole. The nerd let out a pitiful whining moan but it was swallowed up by a startled yelp when Katsuki wrenched him off the toilet and threw him down onto his knees. The sight of him kneeling in front of him, that fucking disgusting face turned to stare up at him, was the final push he needed. Wrapping one hand around his cock and the other into Deku’s hair, he wrenched him in close so his face was hovering right next to his crotch. Two quick pumps was all it took. Grinning widely, an electric burst of pleasure coursing through his body, Katsuki came, covering Deku’s stupid face with a heavy layer of jizz. Deku gasped, stretching his mouth open wide to catch some of it one his pink tongue. Fuck…he wasn’t supposed to get this involved in this but damn…this fucking pathetic piece of shit really was made just to get him off.

“Good boy.” Katsuki purred, his grin growing even wider as Deku moaned happily, lapping up drips of his cum from his lips, “You’ll work hard to satisfy me from now on, won’t you, Deku?”

“Yes…” Deku whispered, looking up at him dreamily. Reclining back, he hefted himself back onto the toilet and spread his legs, exposing his swollen, sloppy hole, “Please…use me as much as you want.”

A wild burst of heat gnawed at the pit of his crotch, demanding to be sheathed inside that incredible heat again. Well, might as well solidify Deku’s training, making sure he really understood his role in society. Couldn’t have this bastard start to believe again he belonged anywhere else other than firmly squashed underneath his foot.
