In the dim light of their childhood home, two siblings, bound by blood and guilt, sneak into a cramped closet. Their bodies press close, hearts pounding with fear and desire. The elder sister, Michelle, guides her brother's trembling hand to her breast, gasping as he tentatively squeezes. She can feel his hardness pressed against her thigh, and her own body responds, wetness soaking her panties. They steal glances at each other, eyes wide with shock and hunger, as they explore each other's bodies for the first time.
