In a cramped closet, two devout siblings, haunted by religious guilt, perform a ritual of purification. The girls, dressed in semi-clothed forms, tentatively grasp their stepbrother's massive, virgin cocks. "You mustn't move!" their father commands, but innate lubrication soaks the shafts as the girls slowly sink down, rubbing their tight, untouched vaginas along the hard lengths while falling back into an intense, taboo lust only to collapse into post-coital remorse and shame amidst smeared juices and spent fluids, praying for absolution from their forbidden desires.
