An apple

 

"An apple?" You say to yourself, why on earth would you want to wear an apple costume to a party? Confused, you make your way to the changing room and see a small shirt and black skirt lying on the seat. Ahhhh must be a schoolgirl outfit, it'd be funny seeing a dude dressed as a schoolgirl so you try on the outfit. You look in the mirror realising how silly you look when you notice your legs are now slim and hairless, you bend over to inspect them and feel your hips and butt gaining fat to feminine proportions. Bending back up you watch as your hands become more feminine and your long black hair grows down to chest length, you grab your chest as pressure builds up with the fat moving behind your nipples, growing your new girly breasts until the shirt pops open! You lift your skirt and notice your boxers are now a pair of cute panties, concealing your new virgin pussy, perfect!
