Caught in the throes of teenage hormones and religious guilt, two siblings find themselves drawn together in the dark of night. Clad only in their underwear, they tentatively explore each other's bodies, their hands shaking with nerves and desire. The girl, her virginal pussy dripping with excitement, guides her brother's massive cock inside her, gasping at the sudden fullness. He, his cock harder than he's ever felt it, begins to move, fucking his sister slowly but steadily, their bodies slick with sweat and their hearts pounding with fear and lust. As they come together, they pray for forgiveness, even as they yearn for more of this forbidden pleasure.
