This happened from when i was 7 all the way to when i quit gymnastics at age 12. Me and my gymnastics friend Sarah always would go pee together and the best part about it is that our gymnastics teacher said that we (her students) could use the boys washroom (mainly because their was only a couple guys and because they were single person washrooms. We took advantage of this and peed in the urinal because it seemed pretty fun. We would go into the washroom then one of us would pull down their tights and panties and hop up on the urinal and pee. Then the other one would do the same. One time we did it with a boy in their too. The thing that reminded me of this is when yesterday me and my gf peed in the urinal at target. Look for the story In the urinal at target.
