Bored and resentful step-siblings, Michelle and her stepbrother, find themselves alone together. Michelle retreats to the bathroom, fingering her wet pussy and stroking her ass, trying to remain quiet. Her stepbrother, excited for a shower, bursts in, catching her naked and vulnerable. They argue, Michelle's anger boiling over, but later, they make amends, masturbating openly in front of each other. Michelle's eyes widen at the sight of her stepbrother's thick, straight cock. Fantasizing about feeling it inside her, she's about to act on their mutual desire when someone enters, forcing them to abruptly stop.
