I take my seat in the back of the lecture hall. Professor is pretty far away but has a clear view of me.. and up my skirt.. I want to have some fun, it turns me on knowing he can barely contain himself. I slowly strip, hoping nobody notices.. I tough myself over my panties before slowly sliding them off. I'm naked in the back of the room and my professor is having a hard time focusing. I rub my pussy until I cum and then quickly get dressed again
