Penny L "Silent Wank"

Penny has asked the college class to do some revision, she wants eyes down and silence, you have other ideas though! Penny is wearing a very short skirt with stockings and suspenders and you can't keep your eyes to yourself, as she is sat on the edge of the desk she unknowingly flashes her panties at you. You get and instant boner and wonder if you can get away with having a sneaky wank in the middle of the college classroom.
