Haunted by religious guilt, two devout siblings squeeze into a cramped closet, their semi-clothed forms rubbing together. Michelle gently pushes her baby brother's massive cock inside her, while her brother hungrily licks her untouched pussy. 'You mustn't move!' their father commands, but innate lubrication soaks the shafts as the siblings slowly, sinfully, sink down, their tight vaginas enveloping their stepbrother's virgin cocks. Collapsing into post-coital remorse, they pray for absolution from their taboo lust.
