Bkdk a/b/o where a quirk brings UA Deku to the future
(This shit KINKY)
Izuku twiddles his thumbs as he stands outside of future-his and Katsuki’s bedroom, listening to the slap of skin on skin and moans coming from the other side of the door.
“Yes, alpha!” future-Izuku whines, and a loud slap tells past-Izuku that Katsuki just slapped him on the ass. Or the face. Maybe he’s into that.
“Little painslut, huh?” Katsuki growls, and past-Izuku feels himself involuntarily slick up.

It’s hard enough to believe that he ends up with /Kacchan/ - the blond still hates him in his time, constantly blowing up in his face and screaming whenever Izuku dares cross his path.
But, as future-Katsuki had told him, that’s just because past-Katsuki doesn’t know how to handle his feelings yet.
The future version of himself and Kacchan had been kind enough to let him stay with them when he’d wound up here in the middle of a battle.

It’s been a little over a week, and Izuku was starting to get a bit used to the flow of things.
Until now.
He was already aware of the fact that future-Izuku and Katsuki have… sex. But he’d been good about avoiding it.

He was just walking to the kitchen for a drink when he heard the future version of himself moan softly, and he just wanted to make sure everything was alright, okay?
He can’t explain why he’s been standing here for ten minutes, rubbing his thighs together uncomfortably.

Eventually, the noise on the other side of the door stops, and a few heated whispers are shared.
“No, you go talk to him!” Future-Izuku hisses, and a moment later, the door opens to reveal a shirtless Katsuki with a towel wrapped around his hips.

“Hey squirt,” Katsuki says awkwardly, scratching his chiseled abs. “Izuku and I were just - showering… when we smelled you out here. Everything okay?”
He’s good enough of a person to not mention the fact that it had been past-Izuku’s blatant arousal that they’d smelled.

“Y-yeah!” Past-Izuku squeaks, holding his hands in front of his slicked sleep pants. “I was just grabbing a… snack.”
“Honey,” future-Izuku coos from the bed, covered in a blanket. “It’s okay if you were curious.”

Past-Izuku’s face is burning, eyes watery with embarrassed tears as he looks at the floor and sniffles. “It’s just… Kacchan hates me and I w-wanted to…”
Katsuki raises his eyebrow when Izuku trails off, tipping the omega’s face up gently with his thumb.

“Don’t listen to anything that little shit says to you,” Katsuki says sincerely. “He’s angrily jerking off to the thought of fucking you every night.”
“Keep in mind that little shit is /you/!” Future-Izuku chirps helpfully from the bed.

“Case in point,” Katsuki grins. “I know all his dirty little secrets. Like when I stole a pair of your panties in first year -“
“He doesn’t need to know that!” Future-Izuku protests.
“He doesn’t need to know that!” Future-Izuku protests.
Katsuki shrugs. “It’s not like the pip squeak is gonna remember any of this. Why don’t we let him watch?”
“Oh my god, I wish people knew how much of a pervert you are,” future-Izuku groans, falling back against the pillows.

“What do you say?” Katsuki asks past-Izuku lowly, his eyes glinting with hunger. “Want a front row seat of what’s in your future?”
Past-Izuku’s blush burns brighter, and he can only nod mutely, stepping into the door as Katsuki clicks the door closed behind him.

Future-Izuku opens his arms, and past-Izuku immediately snuggles into them.
“Kacchan loves you, even in your time. Trust me,” future-Izuku coos. “You don’t have to just watch, you know. Kacchan’s big enough to go around.”
“Kacchan loves you, even in your time. Trust me,” future-Izuku coos. “You don’t have to just watch, you know. Kacchan’s big enough to go around.”
“Y-you’d let me?” Izuku asks his future self, pulling back to look at his face.
“Of course,” past-Izuku says gently, cupping his face. “He’s yours too, you know. You just don’t know it yet.”
“Of course,” past-Izuku says gently, cupping his face. “He’s yours too, you know. You just don’t know it yet.”
Past-Izuku’s eyes flutter closed as future-Izuku tips his face up, their soft, identical lips meeting gently.
“And you call me a fucking pervert,” Katsuki groans, squeezing himself through the towel as he watches. “Fuck, that’s hot.”

Past-Izuku tentatively pokes his tongue out, moaning when future-Izuku’s immediately meets his, the kiss turning from sweet to filthy in the blink of an eye.
“Fuck yes,” Katsuki growls, and past-Izuku peeks open one his eyes just in time to see the towel drop.

Katsuki grabs himself at the base, slowly jerking himself off, the shaft still glistening from being buried deep in future-Izuku’s pussy.
Past-Izuku’s own pussy clenches, feeling himself get uncomfortably slick from the sight.

“Baby boy likes that,” Katsuki commentates, eyes lidded as he watches his mate and past self make out sloppily.
The blond makes his way over languidly, and the two Izukus pull apart with a moan, both of them blushing prettily.
