Johnny Steel and Penny German, step-siblings with a penchant for the taboo, find themselves in a steamy situation. Penny, cute and innocent-looking, is taking a bath when Johnny barges in, catching her off guard. Instead of apologizing, he watches, his voyeuristic tendencies taking over. Penny, initially shocked, plays along, washing herself seductively. The bathtub fills with more than just water as their desires rise. Johnny's hard-on is evident through his towel, and Penny, rubbing her soapy body, can't help but fantasize about his cock inside her.
