Stacey and Amanda are sunbathing by their friend Dave's pool. The sight of Stacey's shapely ass in her bikini gets Alan aroused as he swims around and he slips his shorts down and starts playing with himself. Just then Amanda returns and catches him in the act! She pulls him out of the water by his ear and both girls see his shorts are half down and he has an erection. They are disgusted by him and start calling him a pervert, but as Stacey stares at his erection she becomes flattered that her body caused this.
