Bored and restless, two siblings, both teenagers, find themselves alone in the house. Michelle, an ebony beauty with curves that won't quit, starts touching herself in her room, fingers sliding over her wet pussy and big ass. Her stepbrother, overhearing her, bursts in and catches her in the act. They argue, but later, Michelle propositions him, "Why don't we just masturbate together?" Naked, they explore each other's bodies, Michelle's eyes locked on his thick, straight cock. Just as they're about to cross the final line, a noise startles them, and they quickly separate.
