White full back panty wetting college girl desperation

As I'm doing my work in class I really really need to go toilet, I put my hand up and ask Sir if I can go, but he tells me no, and to carry on with my work. I try but I just cant sit still, I fidget, I cross my legs, I push my hand onto my panties, nothing is working, I'm not sure how much longer I can hold it in, I ask Sir a couple more times, but he's just not letting me go. Oh no, it's too late I think it's started coming out, i look down and my panties are getting soaked, pee is pouring all over my chair and the floor and I just cant stop it. I stand up and it just keeps coming, my bladder was sooo full. And now Sir says I can go, did he enjoy seeing me suffer?
