Two siblings, both teens, find themselves alone at home, their boredom driving them to explore each other's bodies. The brother, hidden in the bathroom, can't help but watch as his sister, Michelle, masturbates, her fingers dancing over her wet pussy and big ass. Caught in the act, they argue, but later, curiosity and desire bring them back together. Naked, Michelle admires her brother's thick, straight cock as he jerks off. Fantasizing about his massive dick inside her, they're interrupted just as they're about to act on their taboo desire.
