Look at you! You've ruined your uniform. I don't care if the other boys pushed you in the mud, it is your responsibility to keep your uniform neat and clean. Do you know how much your step-mom pays for these uniforms? Do you want me to call her and explain that you've come into my office filthy again? No, that's what I thought. I do have an extra uniform. But it is not a boy's uniform, it's a girl's uniform, including satin panties and a mini skirt. You will wear this today or else I will send you home. I don't care if the other students mock you, you deserve to be teased for being such a sissy. Look how short the skirt is! You will have to be careful or else you might accidentally flash the boy students. I bet the boys would make you prance around in just your panties if they found out you weren't wearing boxers. By the way, since you're dressed like a girl, you'll have to use the girl's restroom today. If I catch you at a urinal, you'll have to wear the girl's uniform all week. Go back to class sissy!
