In a house of religious constraint, a young sister and brother find solace in forbidden pleasure. As their guilt-ridden hearts pound, they sneak into the closet, their breath fogging the cold air. The sister, her hands trembling, unzips her brother's pants, revealing his massive, untouched cock. She tentatively strokes it, her lubrication soaking the shaft as she struggles with her conscience. Her brother, equally torn, helps her onto his lap, her tight virgin pussy rubbing against his hardness. They move slowly, their taboo lust building, until they collapse in a mess of spent fluids and whispered prayers for absolution.
