William was over your house for a sleepover. Your mom had let him in since you were in the shower.

Ever since he figured out you had gotten superpowers he’d always ask if he could try on your suit or if you could take him flying.

Obviously the answer was always no. But… you weren’t here, and he was bored, and he knew where your suit was. He was just trying it on for size, posing in the mirror when you walked in. “Dude what the hell!” He screamed before laughing at your reaction, seeing him in your suit.
