A brother and sister, both teens, find themselves alone and horny, their bodies yearning for release. They start by masturbating separately, but the sound of their pleasure drives them to explore each other. Naked, they face each other, their bodies ripe with desire. The sister, Michelle, can't help but fantasize about her stepbrother's thick cock inside her. As he jerks off, she fingers her wet pussy, her ass bouncing in the air. Just as they're about to cross the line, someone enters, forcing them to halt their incestuous encounter.
