Peeing myself at school

I peed myself at school last week. I was thinking sexual thoughts and I met a guy in a chatroom who opened me up to a whole new world of pee fetish. He told me to wet myself just a little bit at my desk and I did, but I just couldn't stop there and I got myself soaking wet. I had to go to the bathroom and clean up, but while I was there I also made myself cum thinking about how dirty it all was. The guy in th made me keep my underpanties on and wear them like that. I felt dirty, dirty and shameful, yet secretly pleased.
