In a cramped closet, devout siblings find solace in forbidden pleasure. The teen brother and sister, haunted by religious guilt, maintain their virtue by steady breathing. Michelle gently pushes her baby brother's massive cock inside her, while he struggles with his own guilt. Their father's distant command, "You mustn't move!" only fuels their innate lust. The siblings slowly sink down, rubbing their tight, untouched vaginas along the hard shafts, their lubrication soaking the cocks. As they reach climax, they collapse into post-coital remorse amidst smeared juices and spent fluids, praying for absolution from their taboo lust.
