I was Cheerleading practice this one afternoon working on dances and exercises. It had been a few hours since the last class go out and I completely forgot I really needed to use the bathroom before practice, but now I was a little too late. While I got ready to do another stretching exercise....I suddenly felt the urge come back and now I was more desperate go then I had been earlier. I tried as hard as I could to ignore it but it only got worse as I reached the point of nearly bursting, and I could already feel large squirts starting leak through my panties. I was so nervous that I suddenly just lost control and completely flooded my panties for a minute straight. There I was in the middle of my whole cheer team peeing my panties uncontrollably. I was sooo embarrassed. I wanted to cry. My instructor let me leave practice to go finish emptying my bladder and to clean myself up.
