Religious siblings, haunted by guilt, find solace in each other's arms. In a cramped closet, they maintain their virtue by staying semi-clothed, but innate desire takes over. The girl, Michelle, gently pushes her brother's massive cock inside her, rubbing her tight pussy along his shaft. Their father commands them not to move, but as Michelle sinks down, taking her brother's cock deep, they can't resist the all-consuming taboo lust, collapsing in post-coital remorse amidst smeared juices and spent fluids.
