Someone please help!!!

I'm looking for the very first porno I watched and I can't the name it starts with a woman in a fur coat getting in a cab then the opens the coat and starts Masterbating while the cabbie watches in the mirror. Then she goes to some type of school then there's a scene where a chick climbs up on a bathroom sink and yells for help then some guy comes in and he goes to help her down but she throws her skirt over his head then they fuck and like 4-6 girls come in and gangbang him. Then I remember at their prom or club or something the one. Chick blows her teacher while he's playing pinball the. The fuck in the coat check room that's all I remember please help!!!
