Daphne Dare, the blonde stepsister, and Alex Jett, her hung stepbrother, find themselves alone and horny. Daphne, with her small tits and big ass, starts masturbating in her room, fingering her wet pussy. Alex, hearing her, enters and catches her in the act. They argue, but the sexual tension is palpable. Soon, they're both naked, masturbating openly in front of each other. Alex's thick, straight cock catches Daphne's eye, and she fantasizes about it inside her. Just as they're about to act, someone enters, forcing them to abort their erotic encounter.
