Minxx Marley, the family's petite, innocent-looking teen, has been harboring a secret fantasy. She wants her rugged, older stepbrother Billy Boston to be her first. With her small, firm body and tiny frame, she's the epitome of a hot, teen babe, and she knows it. One afternoon, she corners Billy, her short, petite form rubbing against him as she confesses her desire. Billy, torn between his step-fantasy and familial duty, struggles with his massive hard-on, trying to resist the tiny, taboo temptation that is his stepsister.
