In a desperate attempt to maintain their virtue, a devout brother and sister retreat to a cramped closet. But their semi-clothed forms and innate lust prove too much to resist. The sister gently guides her brother's massive cock inside her, gasping at the sensation of his hard flesh filling her tight pussy. As they move together, their religious guilt fades, replaced by an all-consuming hunger for each other. They collapse amidst smeared juices and spent fluids, their taboo lust temporarily satisfied, but forever haunted by their forbidden passion.
