In the dim light of the closet, siblings succumb to their darkest desires. The girl, her eyes closed, slowly pushes her brother's massive cock inside her. Religious guilt haunts her, but her body betrays her, lubricating the shaft as she grinds her tight, untouched virginity against it. Her brother, equally conflicted, commands her to remain still. Their secret passion builds, bodies entwined, until they collapse in a mess of spent fluids and post-coital remorse, praying for forgiveness.
