Bored siblings, Michelle and her stepbrother, find themselves alone and horny. Michelle retreats to the bathroom, fingers her pussy, and strokes her ass, trying to be discreet. Her stepbrother walks in, catching her mid-act. They argue, but later, they decide to masturbate openly in front of each other. Michelle takes in her stepbrother's thick, straight cock as he jerks off. She fantasizes about his massive dick inside her. Just as they're about to act on their desires, someone enters, forcing them to abruptly stop.
