One of my friends dads has been perving on all us girls at gymnastics class. Of course parents are going to come watch their practice, but this one girl's step-dad just comes to perv on all us in your leotards. I decided to teach him a lesson and embarrass him by making him cum for me..... but not before I do some pretty heavy teasing and make him hold it in for a while while I stroke him wearing my leotard. I punish him a little too by slapping his big manly step-daddy balls around a bit. He will not forget this!
