Bkdk where Katsuki is an entitled billionaire and Izuku is a shy maid who’s in love with the billionaire who will never notice him. Except one day Izuku is in his frilly maid outfit getting clothes out of the dryer when he gets... stuck. His ass is fully wedged in the door and +

his skirt has flown up, exposing his round, bare ass to anyone who walks by. His upper body is stuck in the dryer bc no matter how much he wiggles his ass, it’s too big to budge. And it’s just his luck that Katsuki has picked that very day to inspect the kitchens and surrounding+

rooms, and therefore happens to be the one who stumbles across him. Izuku’s glad to hear footsteps and calls out only to freeze when Katsuki responds. “I knew you were useless, Deku, but this is new.”
Izuku whimpers and apologises, amazing for help, and Katsuki grabs two +

handfuls of Izuku’s ass, tugging backwards. It just makes Izuku’s ass jiggle, though, and Izuku, surprised at the sudden sensation, moans. The sound echoes in the dryer and Katsuki pauses before saying, “You want me that badly, huh, slut?”
Izuku insists otherwise, but Katsuki +

tells him that he knows Izuku is whipped for him. And then he says, “Fuck, you look so sexy like this. If you’re uncomfortable, tell me to fuck off, but I /want you too/, Deku.”
And Izuku can’t help but say yes. Katsuki doesn’t take a second pushing Izuku’s tiny underwear aside +

and starting to finger him. And if that feels good, Izuku can’t describe how hot it is being fucked on Katsuki’s huge dick as he’s told what a slut he is, and how perfectly his ass was presented for Katsuki to fuck. And Katsuki makes his ass jiggle so hard that when Izuku cums, +

it pops out of the dryer, freeing Izuku as he tumbles back into Katsuki’s lap. Only then does he realise how close they were to being caught. But he doesn’t mind: Katsuki /fucked/ him.

Izuku initially gets promoted to mistress, but it’s not long before Katsuki starts +

courting Izuku properly. Then, a few years later, Izuku becomes the rich spouse of billionaire Bakugou Katsuki
