Delphine Stephenson, a devout woman, struggles with her lustful urges as she shares a cramped closet with her brother. Clad in semi-clothed forms, they try to maintain their virtue, but the heat and tension prove too much. Michelle, haunted by religious guilt, finds herself drawn to her brother's massive cock. She gently pushes it inside her, their bodies slick with lubrication. Hungry for more, she licks and envelops his penis, rubbing her tight, untouched vagina along his hardness. Just as they're about to succumb to their taboo lust, their father's voice echoes, forcing them to collapse into post-coital remorse.
