The other day I was instructing my ski class girls to make sure they all went to the bathroom before we headed up the mountain to ski down. Well of course, in the middle of my short reminder I was giving them I just realized I had forgotten to use the bathroom and I suddenly felt my panties getting really warm and just seconds later I could feel my pee rushing right through my soaked panties and running down my legs. I was too late, I could not regain control of the flow, I was simply peeing too fast to contain it. I turned so red, having totaly embarrassed myself by standing there and peeing in my own panties while I was telling others to make sure they used the bathroom, its more like I really needed to use the bathroom instead of them. To make a long story short I peed continuously for almost a minute before I was done. I had to excuse myself to the bathroom to change into a new snow suit. I'll never forget that day, not after peeing in front of everyone like I did.
