Chad Alva and Paige Owens, stepsiblings in college, find themselves alone in their shared apartment, boredom driving them to explore each other's bodies. Paige, a blonde with natural tits, starts fingering her wet pussy and rubbing her big ass, while Chad jerks off his massive cock. Caught in the act, they argue, but lust prevails. Naked, they masturbate openly, Paige's eyes locked on Chad's thick, straight cock. She fantasizes about feeling it inside her, and they're about to act on it when someone interrupts their incestuous lesson.
