A fair-skinned amateur woman in revealing jogging gear is approached during her run and smoothly talked into visiting a man's home. Posing as an experienced runner, he uses his knowledge of exercise muscles to offer her a sports stretch. It begins seriously, but their bodies remain pressed together and her exposed curves stir his desire. He covers her in lotion and turns the session into lewd sexual play. Slick from head to toe, she gradually begins writhing with pleasure as he leads her through one naughty act after another.
