The Queen Bee's changing room locker.

You decide to go to the Elise's changing room locker. Elise is the school's queen bee. After being the top cheerleader for 3 years, consecutively winning the city's cheer contest, she's become such a huge figure in the school. Every girl wants to be her friend, every guy wants to date her, and everyone is jealous with the treatment she gets from teachers.

You decide to prank her a little bit by going to the girl's changing room, going to her locker (You knew it was hers because it had her name on it), and then writing your name on the locker. You open it, there's her underwear, a plaid miniskirt, and a white top, a slutty version of the school's female uniform. You leave your sweaty boy's uniform inside, with underwear and all, remove your name and write Elise's name, and then leave the girl's changing room. Hopefully this means that your uniform will now be considered her uniform.

You wait until her gym class is done.

She walks out wearing your old uniform, her too big breasts tenting the shirt top. The sweat causes everything to be see through. The pants were too tight, causing her to have the slightest cameltoe if not for the briefs.
