You hare staring up Bonnie's skirt in the changing room and you come up with an idea, you ask her if she would like free membership to the gym. When she says yes you tell her all she has to do is let you look up her skirt at her panties and pussy while you wank, surprisingly Bonnie agrees so you waste no time in getting your already hard cock out of your trousers while she bends over to show you her panties.
