In the dim light of their shared childhood home, a brother and sister find themselves alone, their parents away for the night. The sister, Michelle, a raven-haired vixen with curves that won't quit, begins to touch herself, her body aching for release. Her brother, unaware, enters the bathroom, catching her mid-act. Anger flares, but so does something else - a spark of forbidden desire. They argue, they fight, but the tension between them grows thick, palpable. Soon, they're both naked, Michelle's eyes locked on her brother's stiffening cock. She wants it, needs it, and as they come together, their bodies entwined, they give in to the taboo lust that's been simmering beneath the surface.
