In health class one afternoon there was the normal manditory presentations going on which I really hated because I'm a horrible speaker and I don't think I ever will be good at it but.....anyways I'm standing there explaining my own presentation which of course had to be on the subject of female peeing. As I was speaking, the subject I was covering just happened to remind me how badly I need to go pee. But by the time I realized it, I was a bit too late....I was already peeing my panties before I could do anything to prevent it. Everyone in class almost noticed the rivers of pee running down my legs under my short skirt. Already embarrassed enough at this point.....I had no choice but to just give up trying to control it anymore, I was peeing so hard I had already lost control of myself. I left class that day so embarrassed and humiliated not to mention the fact that I had another accident on the way home in my car. Maybe If I have learned something from that.....I should not drink any water before doing a presentation...because I will almost certainly pee my panties in class again.
