    Summary

    "Oh my god" Mina breathed, entirely ignoring Kirishima’s bright red face and his hands still clamped firmly over his ears. She leaned across the table "Kats. Are you telling me you made your boyfriend stop for four months because you don't know what an orgasm feels like?!"

     

    Katsuki knows how orgasm feels like! What he doesn't know is like why he felt something weird everytime they do something intimate!

    "shut up! I know what's feels like!"

     

    ---

    Where in Katsuki challenge his amazing boyfriend izuku to make him squirt, and immediately feel like he will regret it.

    Summary

    Izuku always thought of himself as a responsible, rule-abiding alpha. He kept his suppressants on schedule, followed the Omega Relief Program protocols to the letter, and never, ever got attached. But somehow, none of that prepared him for the omega that was Kacchan.

    Or

    Katsuki's has had it with Izuku and his omega-of-the-day bullshit. So, what’s an unhinged genius to do? Easy: baby-trap the Symbol of Peace.

    Summary

    •Katsuki breaks first.
    •Izuku doesn’t stop him.
    And once the power shifts between them, there’s no turning back.
    This is what happens when two soldiers can’t stop circling each other—
    and one finally tells the other to kneel.
    A slow-burn descent into need, obsession, control, and the kind of devotion that ruins you.
    He says, "Be good."
    And Katsuki listens.
    (Dom!Izuku / Sub!Katsuki • Post-war • Rivals to lovers to his.)

    Summary

    Rising up on his knees, Izuku picked himself up and slammed himself back down on Katsuki’s cock, again and again and again.

    Squeezing Katsuki’s throat, he leaned down, hips rolling all the while, to pant warm puffs of breath against his ear. “Like that, Kacchan? Need me to fuck you just like that?”

    And yeah, that was a real come to Jesus moment right there for Katsuki.

    OR: Katsuki’s never bottomed before, which is all well and fine. Until Izuku starts acting up.

    Summary

    Katsuki stares at the wall in front of him. A vein pops on his forehead.

    So, everyone thinks Katsuki can’t handle an alpha long-term, huh?

    That’s what this is. They think he’s not good enough for an alpha. Just because he’s a beta.

    Well, fuck all of them.

     

    Or; beta Katsuki’s downward spiral (and then comeback) while dating the very irritating, pathetic, and annoyingly loving alpha, Izuku.
