With their parents away, Michelle and her younger brother find themselves alone and tempted. As they each retreat to their rooms, they can't help but think of the other. Michelle, a curious and horny 18-year-old, tentatively touches herself, her fingers brushing against her virgin slit. Meanwhile, her brother, barely legal himself, struggles with his growing erection. Unable to resist, they seek each other out, their bodies pressing together in a dance of pent-up lust. Michelle's hand wraps around his hardness, guiding him inside her. As they lose themselves in each other, the house creaks around them, their taboo passion echoing through the empty halls.
