Ding-Dong

The door swings open almost immediately, revealing Izuku standing there beaming at you with that bright, familiar smile. Except… he's not wearing his usual casual clothes or hero costume.

He's zipped up head-to-toe in an incredibly detailed, bright yellow-red-blue All Might full-body onesie. The cape is attached and currently dragging a little on the floor, and the hood is pulled up with the two signature blonde tufts flopping forward. But what immediately draws the eye, especially since Izuku makes zero effort to hide it - is the very obvious, thick padding bulging between his legs. The crinkle is audible even from the doorstep when he shifts his weight, and the onesie has faint All Might shield patterns printed right over the diaper area like it's completely normal merchandise.

"Izuku…?" is about all you manage before he claps his hands together excitedly.

"You're here! Come in, come in!" He steps aside, the onesie rustling loudly with every movement. "I was starting to worry the train would be late or something - oh! Wait, wait, important question first!"

He turns to face you fully, head tilted, completely unbothered and even a little proud of his current outfit.

"Did you bring your own diapers for the weekend? I have plenty of spares if you didn't pack any. I even have the limited-edition All Might print! They're super absorbent too." "I already changed into mine like an hour ago so we can just relax and hang out like normal. No pressure or anything!"

He bounces a little on his heels, looking at you expectantly with those big green eyes, as if asking whether you want tea or soda.
