Ever since I can remember I became turned on when I became desperate to pee. I would be playing or in school or out shopping and would wait until the absolute last moment and run for the potty letting out squirts and wetting my panties a little get into the potty and furiously masturbate and cum a few times as I sat there. All in great fun and excitement and enjoyed alone until my HS senior prom. I wore a very tight fitting electric blue full length gown and danced with my bf for hours and drank plenty of soda and building my sexual excitement of looking very hot in my dress and makeup and sexy up do and fantasizing about rubbing and fingering myself to numerous orgasms in a one of the many single yet beautiful roman style ladies rooms. As the moment approached my bladder strained and my clit ached. I felt my first little squirt wet my panties and I left for the potty. I got on the glass elevator to go to the 2nd floor where the restrooms are and the elevator got stuck. Within a few minutes things got real desperate and I began to panick as more n more eyes became fixed on me in the elevator. A couple more small squirts soaked my panties but I saved up all night and knew it was gonna be like Niagra Falls when I would explode. A few moments later in front of a couple hundred classmates and tears streaming down my face my bladder gave way and gushed out with lots of pressure. I made it worse by grabbing my pussy making my pee shoot all over and quickly changing my silk electric blue gown to a royal blue piss soaked gown. Some watched in horror but most everyone pointed and laughed as I peed myself. I turned away and faced the door for two reasons shame and an urgent need to stop the severe aching in my clitty. I orgasmed numerous times before being rescued. When the banquet manager opened the door he had a nasty smile on his face. He said I could wait back in the office area and I did. Two other men were back there also. When the manager came back he apologized for the elevator miscue. He then leaned in close and thanked me for the show he and the other men watched me masturbate via the elevator camera. I looked at all of them and each were rock hard. He wrapped a blanket around me and helped me to my car. Next morning I washed and returned the blanket and he showed me the video. I was grateful no one else knew and offered him a blowjob. He accepted. I still do the pee thing all the time with and without my husband.
