Katsuki heard muffled, annoying noises which he immediately recognized as the nerd's sobs. "Fucking Christ," he muttered, putting away his phone and tucking it into his back pocket, before making his way over to Deku's room. He pushed the door open. https://twitter.com/problemadick/status/1271939796844318721
Deku sniffled and wiped his nose before turning to the blonde standing in his doorway. "K-Kacchan..."

"You're always fucking crying about something. The hell happened?"

Deku wiped at his face, attempting to regain his composure before answering.

"I-I stepped on a dog's foot."
Katsuki was dumbfounded.

"Are you fucking serious??! /That's/ what you're crying over??"

Deku's eyes welled with tears once more before he broke into sobs, hiccuping like a fucking idiot.

"Y-You weren't there!! It yelped in pain, a-and I felt so bad...!"
Katsuki rolled his eyes.

"Oh, shut the fuck up, you've got no reason to cry. The dog's fucking fine."

Deku only sobbed harder. It grated Katsuki's gears. Deku was always so fucking annoying, crying like a bitch over nothing. His wails pissed Katsuki off.
The nerd shouldn't be crying for no reason. But Katsuki could certainly give him one, and relieve stress while he was at it. He'd never admit it, but every time Deku cried Katsuki found himself wishing he was the reason.

"Be quiet or I'll give you something to cry about."
Katsuki's harshness didn't help Deku calm down, and the idiot's cries only fueled Katsuki with more and more anger. He snapped.

Katsuki slammed the door, making Deku jump. He stalked over to Deku's bed and grabbed the shorter boy by the collar of his shirt.
"You're so fucking annoying," he hissed. He tossed Deku back onto his mattress and grabbed the tissues at his bedside and bringing one to his nose.

"Blow," he demanded, straddling him.

Deku blew and then Katsuki held his nose and covered his mouth, restricting Deku's airways.
Katsuki released him and Deku gasped for air, looking pathetic. He tossed the used tissue aside. Deku wasn't sobbing over that stupid animal anymore.

"Kacchan...?"

Obviously he was too stupid to know what was going on.

"The only thing that should be making you cry is /me/."
Then Katsuki descended upon him, capturing Deku's lips in a demanding kiss. Deku was confused, but Katsuki gave him no time or space to protest, shoving his tongue into the other's mouth. Deku didn't understand why Katsuki was doing this but it felt kind of nice to be kissed.
Not that he'd had any previous experience. He felt like Katsuki was consuming him. Deku knew he didn't have a say in whatever was happening but he simply didn't have the strength to fight and would anyone else have cared enough to kiss his gross swollen face after crying?
Katsuki broke the kiss and began undoing Deku's tie.

"Stupid Nerd, you could've changed at least before bawling. This is annoying."

Deku's eyes shifted to Katsuki's face as Katsuki undid his clothes, and he realized then that Katsuki wasn't going to stop for anything.
"Kacchan, um--"

"Sit up," the blonde demanded.

Deku complied as Katsuki undressed him and tossed his uniform to the ground carelessly. Deku would have to iron them later.
Deku could feel Katsuki growing in his pants when they kissed again, Deku making a measly attempt to return
Katsuki's passion even with his inexperience. Katsuki bit his lip and Deku moaned. The blonde pulled back to chuckle.

"Sensitive bitch," he commented.

Katsuki pulled off his shirt and Deku marveled at his body. He found himself really drawn to Katsuki's pecs and cursed
his own chest for not looking like that instead. Katsuki leaned down to start kissing Deku's neck, nipping at it and feeling heat travel through his body with every little moan the stupid nerd let out.

He reached down & unbuckled Deku's pants. Deku blushed.

"Um, I've never--"
"I know, fucking nerd. You gonna let me?"

Deku nodded.

"Good, cuz I wasn't stopping either way."

Katsuki reached down and rubbed Deku through his boxers. Deku gasped and looked down.

"Keep your eyes on me, Deku, you dweeb."

Deku looked back up to Katsuki. Katsuki smirked.
He got off of Deku to readjust their positions. When Deku's legs were straddling either side of Katsuki, he gripped Deku's waistband and pulled the boy's bottoms off in one fell swoop.

Deku covered himself with his hands, embarrassed.

"Move your hands, fuckface."
Deku shook his head.

"Now," Katsuki growled, sending a shiver through Deku's body that he wished was fear.

Deku removed his hands for Katsuki obediently. Katsuki smiled down at him.

"Good boy. I'm gonna make sure you cum lots tonight," he promised.

Deku whined in response.
Katsuki was elated at the thought of being Deku's first, of leaving a mark on him so prominent that he'd never forget, no matter who the nerd decided to be with later.

The blonde licked his lips and gripped Deku's thighs, spreading the boy's pretty little pussy open.
Katsuki kissed up the side of his thighs, tiny, barely-audible whimpers leaving him. He grazed his teeth against Deku's inner thighs and Deku wailed, the sound of it going straight to Katsuki's cock.

"Fuck, you really are sensitive," he groaned.

"K-Kacchan, please..."
Deku's hole was wet and twitching already, desperate for attention. But Katsuki wasn't going to give it. Not yet. He teased around it, kissing and suckling at Deku's thighs, palms collecting sweat.

"K-Kacchan, your hands..."

He only smirked in response. He knew his hands were
getting warmer. Katsuki fired off tiny sparks and Deku keened, arching his back and moaning like the walls weren't stick-thin.

"Hah, fucking masochist."

Not that Katsuki cared if anyone heard.

"Kacchan, /please/..." Deku begged again.

This time, Katsuki obliged.
Katsuki took a long, slow lick, reveling in the way Deku yelped when he flicked the boy's clit with his tongue.

"Ohh, fffuuck, Kacchan, oh god."

Katsuki had just made him curse, and boy did he fucking love it. He kissed and lapped up Deku's folds, eyes flicking to Deku's face.
He was pink, and panting hard, and the way he bit his lip when their eyes met made Katsuki want to wreck him all the more. He wanted to talk, to call Deku a filthy slut for getting eaten out in broad daylight, for moaning like a little bitch when their classmates were nearby.
But he didn't. He wouldn't stop. He pushed his tongue inside Deku, tasting him thoroughly and breathing in the smell of Deku's arousal. It seemed to embarrass the nerd but it wasn't like Katsuki gave a damn. He just wanted to keep him moaning, whimpering, a shaking mess
completely under Katsuki's control.

He refocused his attention to Deku's clit.

"Wai-- Kacchan, I can't!" Deku started wailing, high-pitched and desperate. Katsuki knew he was getting close and applied more pressure. "Fuck, oh god, no, stop! I'm gonna cum!"
He allowed Deku to tug at his hair and he couldn't say he hated the feeling. Deku was so fucking loud and it was hot as fuck and Katsuki decided to use his fingers to push Deku over the edge. Deku was looking at him, eyes heady with lust, and Katsuki moaned.
Deku came hard, moaning out "Kacchan" for anyone in close enough proximity to hear. Which might have been to at least 3 doors down. Katsuki sat up, licking his lips.

"Noisy slut," he mocked, smiling, thankful he could finally get that out. "You tryna let everybody hear you?"
Deku shivered, his body still recovering.

"I-I wasn't trying to...Kacchan felt too good," he said, breathy.

Everything that was coming out of Deku's stupid little mouth was going straight to Katsuki's cock and he almost couldn't handle it.

Almost.
"Don't go thinking we're done, idiot. Get up."

Deku did as he was told and the fact that his body was still shaking had Katsuki elated. He sat down as Deku stood in front of him, in all his glory. He wanted to play with Deku's nipples too, but he had his binder on.

"Hey, nerd."
"Mm?"

"How old is that thing?"

"Ummm, like 4 years? Why?"

"Great, I'm gonna burn holes in it so I can play with your nipples too," he stated.

"Wha--"

It wasn't up for debate and the deed was done before Deku could really protest.

"I'm surprised that didn't burn me."
"I'll buy you a new one. And I have more control than you think, Deku."

That was the case for this situation, too. Katsuki pulled Deku into his lap and they kissed once more. The blonde broke away to kiss down Deku's neck, fingers digging into Deku's ass.
"Why do you got a mirror here, nerd?"

Deku was confused.

"So I don't leave my room looking like a mess?"

Katsuki leaned in, mouth by Deku's ear.

"Not that. I mean..." Katsuki paused to spread Deku's ass apart. "I can see everything like this," he purred.

"Kacchan..!"
"You telling me you don't masturbate in front of this mirror?"

Katsuki spun Deku around and spread his legs open.

"Fuck, look at you," he breathed, trailing his hand down touch Deku's clit again. Deku whined. Katsuki grazed his teeth against the boy's neck. "You're so wet."
Katsuki moved his fingers slowly in a circular motion, with just enough pressure to make Deku needy for more.

"Don't look away," he ordered, voice just above a whisper.

Deku wanted to protest, but he couldn't. He noticed Katsuki's eyes on him in the mirror and blushed.
Katsuki's fingers traveled lower, and he kissed the freckled skin on Deku's shoulder. Deku watched as Katsuki spread his lips apart. "So pretty," he said, before putting a finger inside. Deku moaned, not just because it felt good but because it was erotic to see his own flushed
face, to watch his own body react to Katsuki's touch, to actually look at himself and see how lewd he was. He leaned back into Katsuki for support and open his legs wider.

"Oh, you want more, Deku?"

Deku nodded and Katsuki pressed another finger inside. With his legs propped
up he could see his own hole tightening, clenching around Katsuki's fingers. It was too embarrassing to watch, so he focused on Katsuki instead.

The blonde kissed his neck and whispered "I'm gonna make you feel good, baby. So good that you start crying."
Deku shivered and moved his hips, tired of Katsuki's slow, teasing fingers.

"P-Please Kacchan, I need more...!"

Katsuki trailed his free hand over Deku's exposed abdomen, feeling the boy's muscles contract beneath his fingers.

"Can you handle it, nerd?"
Deku nodded desperately.

"Don't forget, you asked for it."

The change was immediate. Katsuki quickly picked up the pace, thrusting his fingers into Deku without mercy. Deku whimpered, throwing his head back when Katsuki teased one of his nipples.

"Ah..! Hah! Kacchan...! Mn!"
Deku had his head resting against Katsuki's shoulder, eyes shut tight as he gripped the blonde's shirt for some kind of stabilization.

"I didn't say you could stop watching, Deku," Katsuki told him.

Deku weakly opened his eyes and lifted his head to watch. Katsuki felt Deku
instantly tighten around his fingers and he smirked.

"Fucking slut," he teased.

Katsuki hooked his fingers and Deku wailed, lifting his hips as if to get away from him.

"K-Kacchan..! Wai-- Stop! I'm gonna piss myself!"

The blonde chuckled. "No you're not, you're just gonna
cum, stupid."

Deku kept struggling against him, but he was too weak, his mind too foggy to actually break away.

"Fuck, Deku...you look like such a whore..." Katsuki growled, sending a shiver through Deku's body.

"Kacchan, please stop! I can't! I can't, fuck! Ah! Ah! I'm--"
Deku came hard, squirting so much that he dirtied his mirror and made a mess of Katsuki's pants.

"Shit," he said. "You came so much."

Deku didn't-- more like /couldn't/ respond. He was limp against Katsuki, eyes closed, still shivering. He looked so cute.

"Hey, nerd."
Deku opened his eyes just a smidgen, enough for Katsuki to know he was listening.

"Are you good?"

Deku nodded.

"Good. You got lube?" Not that it was necessary, what with Deku having cum so much already. Deku pointed to one of his drawers and Katsuki lifted Deku up, gently
setting him down on his bed. He opened the drawer and found the lube, as well as a cute little butt plug. It was a bunny tail. Katsuki searched his other drawers for a matching set of ears and smiled when he found them buried under Deku's dumb t-shirts.

When he moved back to the
bed, Deku still had his eyes closed and had rolled over to his stomach. Was he sleeping? They weren't even close to done. Katsuki covered the little plug in lube, then spread one of Deku's cheeks apart. He didn't stir. Well, this was sure to wake him up. Katsuki pressed the tip
of the plug against his hole, earning a startled squeak before he shoved the rest of it in. The intrusion made Deku yelp.

"Hey, bunny," Katsuki said, smirking.

"K-Kacchan...!!"

Deku rolled over and looked up at him with angry eyes. Well, at least as angry as Deku could look.
"That went in easily. You do that a lot?" Katsuki asked, swiftly putting on the headband before Deku could protest.

"Th-That's private information."

Katsuki laughed.

"You can't sleep yet, bunny, we've barely even started."

"I really don't think I--"

Katsuki gave him a stern
look. "This is what you asked for, Deku. Don't worry, you'll feel good."

Katsuki stood and slipped off his pants, revealing a massive cock.

"Oh fuck," Deku muttered. "You plan to put that thing /inside/ me?"

Katsuki looked at Deku like he'd just grown five heads.

"No shit."
Deku groaned, but truthfully felt insanely turned on by the thought. Katsuki crawled back on top of Deku, admiring him for a moment before leaning down to kiss him. Deku quickly tangled his fingers in the blonde's hair, still eager despite his fatigue. Katsuki trailed soft kisses
down Deku's neck, before sinking his teeth into skin and sucking, eliciting a moan so erotic that Katsuki thought he might lose it right then.

"Fuck," he breathed. "Stupid nerd. So fucking cute."

He moved further down Deku's body, sucking at a nipple and tweaking the other with
his fingers.

"Ah! Kacchan...Kacchan!"

The more he heard Deku moan that nickname, the less and less he hated it. It was staring to sound like music.

Katsuki stopped, putting his hands on the underside of Deku's thighs and pushing them back to lift Deku's hips. He grinded his
cock against Izuku's cunt, earning another sweet moan from the younger boy.

"I'm gonna make you cry. And I better be the only thing that makes you cry this hard for now on," he stated, with the sort of finality that meant Deku had no say.

Deku never had a say. He didn't mind.
Not if it was Kacchan.

Katsuki continued grinding against him, but wouldn't enter him. Deku looked up at him with pleading eyes.

"Heh, such a needy little bunny. You want something?"

"I want you, Kacchan."

"Do you, now?"

Deku moved his hips up to create more friction.
"Yes, please, Kacchan, please-- I'll do anything, just--"

Katsuki pushed himself inside Deku slowly, chuckling at his little gasps and streams of profanity. "Oh fuck, ohfuckohfuck, Kacchan you'resobig oh /fuck/."

"You were already going to do anything for me, Deku."
Katsuki pulled out excruciatingly slow, smirking as Deku's eyes rolled back. Katsuki was going to fuck him stupid.

He shoved himself back in and Deku's legs were already shaking.

"Kacchan, I can't! Oh, god, I can't!"

Katsuki was barely moving and Deku was already a trembling
mess.

"Does my cock really feel that good for you, nerd?"

Katsuki kept pumping his hips at a slow pace, gripping Deku's sides and digging into his skin as he shook.

"Kacchan, I really can't, I-I'm gonna cum already, please--!"

”Yeah? Let me help you out then."
Katsuki began thrusting into Deku and he moaned and whined like an idiot, wailing cries rising in volume until Katsuki had to pull out to let him cum. But as soon as Deku stopped squirting Katsuki entered him again, giving the younger boy no rest.

"P-Please, I can't, Kacchan!"
But Katsuki didn't listen. This was exactly what he'd wanted and exactly what Deku had asked for.

"You said you could handle it."

Deku had tears trailing down his face. He looked so fucking pretty like that and it only made Katsuki fuck into him harder.

"Kacchan! Kacchan!"
Katsuki dug his fingers into Deku's hips and thrusted harder.

"That's right, bunny, moan for me," he growled.

Deku was losing it. It was too much and too good and he couldn't even tell whether or not he was still cumming because his body wouldn't stop shaking and he couldn't
do anything except clutch the sheets below him and moan broken versions of Kacchan and words of profanity that he never expected to use so much and certainly not all at once.

"Kacchan, please, fuck, I'm gonna die it's too much I'm gonna die--"

"Die, then," Katsuki quipped.
Deku came again and swore he saw stars. He could barely keep his eyes open as Katsuki drove into him relentlessly, unable to do anything as he got used like a toy. Katsuki's growls grew deeper in volume and his thrusts lost rhythm. When he finally came Deku was relieved, despite
being a little upset that Katsuki had cum inside him without his permission. But he couldn't say he hated the feeling. He sighed deeply, glad to finally rest. But then Katsuki picked him up and tossed him on the floor, directly in front of his mirror.

"Kacchan, wai--"
Katsuki plowed into him again, this time from behind. It took everything Deku had just to stay on all fours while Katsuki's cock /bullied/ him. Katsuki grabbed Deku's hair, forcing his head up, forcing him to watch himself.

"Look at what a pretty whore you make," Katsuki said.
Deku looked absolutely wrecked, even to himself. He looked at Katsuki through the mirror, begging and pleading for him to stop.

"No. I've only cum once, nerd. Hardly seems fair."

Deku couldn't do anything but cry. He was so sensitive, it hurt but it felt good, it felt so good!
Kacchan was giving him so much pleasure.

"Fuck," Katsuki laughed. "Look at you!! You're in fucking /bliss/. You like being 'Kacchan's' little cocksleeve, huh?"

"Y-Yes, Kacchan...!" he cried.

"If you like it, then fucking say it," he demanded.

"I-I like being Kacchan's
little cocksleeve...!" Deku moaned.

He couldn't think about anything else. All he wanted was more of Kacchan for however long he was allowed to have him. He loved it while Kacchan gave him wave after wave of pleasure, it didn't even matter that he couldn't control anything.
He didn't know how long it had been when Katsuki finally stopped, leaving him a dripping, drooling, cum-filled mess on the floor of his bedroom, but he remembered the words he'd been left with.
"I don't give a damn what you do from here on out. But remember.../this/ is what you're best for, Deku. You're my pretty bunny. /Kacchan's/ little fucktoy."
