Hidden in the changing room, a curious boyfriend watches his girlfriend undress, her string thong barely containing her excitement. He strokes his growing erection as she bends over, giving him a perfect view of her tight pussy. But his lust gets the better of him, and he lets out a moan, alerting her to his presence. She turns, shocked but intrigued, and decides to put on a show. She spreads her legs, rubbing her clit until she cums, her boyfriend's load following soon after, splattering on the floor between them.
