In a cramped, dimly lit room, a brother and sister, both horny and restless, give in to their taboo desires. The sister, Michelle, starts first, her fingers dancing over her clit, eyes closed, imagining her brother's touch. He watches, his cock tenting his pants, before joining her, stroking his length to the sight of his sister's pleasure. Their eyes meet, and the dam breaks. They strip, Michelle's breasts heaving, her brother's cock standing proud. They touch, tentatively at first, then with urgent need, until they're interrupted by a knock at the door, forcing them to scramble for cover.
