Yes

Be fore you leave you walk around pulling on all the lockers, hoping to find an empty one. Luckily enough you yank one open, you have no clue whose it is, but there is a full outfit. The only problem was that it was a guys outfit; cargo shorts, a star wars shirt, and red boxers. Either a boy has a secret locker in the girls room, or one of your classmates crossdresses. You snatch the boxers and throw them on. They are longer than any underwear you've ever put on, and they almost are the same length as your skirt, however, they are super tight. They press into your pussy, basically giving you a permanent wedgie and also showing off the shape perfectly. Closing the locker, you walk out with confidence, now clothed. The second the door closes behind you you hear coach yell your name. You spin around and walk over to him. "Hi sir, I'm sorry I was late; female problems." "Your 'Female problems' took 15 minutes of class time so I'll have to think of a punishment. And where is your uniform, you can't do pe in a skirt and loose t-shirt." He angrily spits back. Coach had always been a bit of a perv; walking into the girls room to "check on them," making girls do extra jumping jacks if they forgot a bra, things like that. You thought he would've asked for proof of your 'lady problems' in the form of flashing him or something gross. Instead what he says next makes you blush super hard; "What are you wearing under there?" You know that he'll punish you if you argue, so you grit your teeth, look away from him and lift up your skirt. "Oh, shorts. Then you don't need a skirt." He reaches down and yanks off your skirt, leaving you in skin tight boxers. "Whoa, isn't that boys underwear? I know your punishment, you are a boy for the day." Most of the time the boys and girls would be separated so the boys don't get distracted, and if they ever played a team game it was shirts and skins (Boys and girls). "What, you can't do that. They can basically see my vagina." "I can do that, and maybe wear a uniform next time." He walked away to address the class before you could respond. "Alright kids, we're going to be practicing wresting. Split into shirts and skins and we'll make it interesting this time. The winner of a match gets to dare the loser anything. All dares must be run by me, if you don't do a dare, you fail the class and stay back a grade." You walk over to Coach again "Um, sir. I know I'm a guy today, but I can't be skins. They would all see my tits." "I don't care, none of the other boys are complaining." And with that he walked away to reff the first match. You decide it's not worth it, worse things have happened in this gym anyway. Normally all you had to do to win was ball tap the guy you were up against and then dare him something horrible. 90% of the dares in pe were sexual, you had **** the boys to do some pretty bad things. There was one really skinny boy named Ronny who you had **** into a chastity cage that another girl had. He would come to you every break for a week and you would edge him with the promise of cumming that time. After a week, you made him eat the massive load that shot from his cannon. You had never been nude in front of your class, no one had. That was the one rule, you could make them do anything as long as they stayed clothed. Your tits now on display, you turn a deep red and hold them in one arm. You catch Ronny staring at you from across the gym, next to the mat where a guy and a girl are wrestling. Ronny beckons you over.
