In a cramped closet, siblings Michelle and her brother maintain their virtue, or so they try. As they huddle together, Michelle's guilt-ridden mind drifts to her brother's massive cock, untouched and yearning. She gently pushes it inside her, her body trembling with religious guilt and lust. Their father's voice echoes, "You mustn't move!" but Michelle's wetness betrays her as she rubs her tight pussy along her brother's shaft, losing herself in taboo pleasure.
