His hands were around Katsuki's waist, forcefully guiding him towards the bed.
"You know what you do to me, Kacchan?" he purred, the muscles under his fingers tensing.
Katsuki was still in his hero costume, headpieces and gauntlets discarded by the door.
"Fuck off, it was just a presentation f-for the students," he breathed, stuttering as Izuku's thumbs traced his adonis' belt.
"How about you give me a presentation?" he said, rolling up the sleeves of his shirt to his biceps. "Strip."
Katsuki's face reddened. He sputtered "You can't just tell me to 'strip' who do you think I am? I'm not some common whore--"
Izuku gripped his chin. "When I give you an order, you complete it," the blonde's eyes unfocused as his face was brought to Izuku’s. "Am I clear?"
Katsuki sucked in a breath, "Yes sir."
He began to undress, his hero costume sliding from his body like water. Izuku sighed and rolled out his shoulders. He stepped back and watched as Katsuki's body became more and more exposed, his boxers remaining on.
"Everything. Come now, we've done this so many times and you still forget? Really. It's not that difficult to remember"
The room's cold air brushed against his fingers as he reached out and snapped the band of the boxers against Katsuki's waist. There was a spot on the crotch, slowly growing darker and darker, Katsuki’s precum leaking through his underwear.
"mph- stop."
Izuku grinned. "So sensitive already? We're just getting started, Kacchan."
"Stop teasing me," He growled.
Izuku's eyes darkened and he shoved Katsuki onto the bed.
"Brat." He ripped the boxers off of Katsuki, the fabric tearing around his fingers.
"Turn around. Present." Katsuki scrambled to comply.
"Faster." He brought a hand down on his ass, the sound sharp and resounding.
“D-Deku please just—”
“Deku deku deku, is that all you say? Like a broken record.” He slapped Katsuki’s ass again, his own palm stinging from the contact.
Katsuki choked out a whimper.
The marks Izuku was leaving were like brands, heating up his body. He could feel it, the writhing need for release already beneath his skin. He knew Izuku could tell as well.
Presenting, he waited. For something, anything. The lack of contact leaving his body bare. He waited. Another slap or something, a touch maybe?
“I can tell you want something, I wonder what it could be,” he cooed.
He brought a hand to Katsuki’s ass, kneading the skin and fat, watching as it moved beneath his fingers. He stretched the cheeks apart, that perfect, pink hole winking at him from where it was hiding.
Izuku licked his thumb and brought it to the hole, circling the entrance and wetting it lightly.
Katsuki bucked his hips, trying desperately to stop himself. He wanted it already, damnit. He needed that cock inside him, touching the hard to reach places and turning his brain off.
Izuku steadied his hips, holding them firmly in place. “Use your words Kacchan. You can do that for me, can't you?” his hands were digging into Katsuki’s skin, most likely leaving marks for the days to come.
He mumbled something unintelligible into the pillows.
Izuku grit his teeth and slapped the blonde’s ass harshly.
“Ngh fuck,” he yelped. “I said fuck me you fucking idiot, God.”
“Not good enough.” Izuku snarled, hitting Katsuki’s bruising ass again.
“SIR. Sir, please fuck me,” a gutteral moan was stuck in his throat.
Izuku huffed. He wanted this too, wanted to fuck katsuki’s brains out, make him beg and cry until his voice was hoarse from pleading.
He assumed Katsuki was loose enough from their escapades last night. Even so…
A little stretch wouldn't hurt.
Izuku unzipped his pants, shoving his boxers down just enough that his cock could spring free. It twitched eagerly, pre glistening at the top of the head.
Katsuki looked back at where Izuku was, grabbing the lube and uncapping it.
Katsuki hissed as the cold hit his hole and Izuku smeared it around with the head of his cock.
“Sir, please—”
“Shut it.” He groaned, rutting against Katsuki’s entrance. “Just—oh fuck—just shup up”
He shoved in, the stretch burning as Katsuki shoved his face into the sheets and groaned.
“You’re so tight, god this hole—nothing but a fucking hole aren’t ya,” He huffed.
“S-S-Sir please ‘s too much” Katsuki whimpered into the sheets, ass in the air and his thighs shaking from the pounding Izuku was giving him.
He scoffed. “Awe, thought the great Dynamight could handle anything,” Bringing his hands to either side of Katsuki’s head, he leaned down to his ear.
“Didnt think any pro hero had it in them to be such a slut,” He purred. “People always thought you were so high and mighty,” He punctuated every word with a thrust. “Makes me wonder what they’d think of the number one hero reduced to nothing but a mindless cumdump.”
Katsuki’s eyes rolled up into his head and Izuku could feel his insides tighten.
He barked out a laugh. “You liked that? God, you really are pathetic.”
He hammered at Katsuki’s insides, his cock hitting his prostate head on. The sheets around the blonde’s face were wet with drool and tears, his eyeliner smearing off onto the white sheets.
“S-So good, thank y-you sir,” he whimpered, bucking his hips back against Izuku’s to rub his own erection against the sheets.
Izuku gripped his ass, pulling the cheeks apart to watch his cock piston in and out. Katsuki was sucking him in every time he pulled out even an inch.
“So fucking greedy,” he murmered, speeding up his thrusts. “Such a greedy slut, you know that, Kacchan?” he grunted, slapping the blonde’s ass again, putting One For All into it this time.
“AH! F-FUCK!” Katsuki cried, cumming harder than he ever had in his life into the sheets. His back arched as he threw his head back.
“F-fuck, sir, thank you thank you—”
“Shut up!” He wrapped his hand over Katsuki’s mouth.
“Mph!”
Izuku began speeding up, thrusting recklessly and as hard as he could, each plunge of his cock punching whiney moans from Katsuki.
“Gonna cum, fuck” He groaned. “Gonna turn you into a useless little bitch, you like that idea, Kacchan?”
He nodded frantically, crying out behind Izuku’s palm as he felt the man’s cum flood into him.
He forced himself inside a couple more times for good measure before shoving Katsuki off of him.
“Fuck, look at that,” He murmered, looking at his handiwork as cum bubbled out of Katsuki’s hole.
