Clothing!

You get up and look for clothing, any clothing, that would fit your new body, and one look at your full-length mirror confirms how hopeless this is.

You're a head taller than you were before and your proportions have utterly shifted from having hips and a small bust to having a slim waist and wide shoulders. There's only one realistic solution: raiding David's room.

Luckily your brother is just a year and a half younger, and roughly your (new) size. He's also gone on a trip with a friend for the week. You quickly tiptoe your way over to his room and slip inside, then start opening drawers.

God, what a mess. You didn't expect him to fold everything, but he doesn't even sort it, just shoves all his boxers and shirts and pants into the same drawers, making you have to sort through them all to find everything.

Oh, yuck... are those condoms? Your cheeks grow warm as you confirm that yes, your brother has an unboxed chain of condoms buried in his drawers. You try not to think of him doing sexual things with anyone and just grab some boxers that look undamaged, feeling a shiver of weirdness at the sensation of the cloth, thicker than any panties, sliding over your unfamiliar legs as you pull them up after stripping off the wholly insufficient underwear you had on last night.

Wow. That feels... pretty nice, actually. The boxers are a bit tighter than you expected, but warm and kind of... cozy?

Jeans go on next, also feeling a bit too tight at the crotch. Are you... big? Down there? Or are the jeans just a size too small for you?

Last is a shirt, a simple olive t-shirt with short sleeves that'll show off your muscular upper arms... you spend a moment running your hands over them, surprised by how good they feel. How good you feel. Your arms and legs are longer than you're used to, but overall your limbs feel... powerful.

You see a pullup bar in your brother's perpetually open closet and lift yourself with just a tiny bit of effort. Despite feeling heavier, you have so much more strength in your upper body that you can easily do it again, then again, and again barely winded when you set yourself down.

Wow, this new body feels good. You wonder what else you can do with it...

Oh shit, just five minutes left!
