In a cramped closet, religious guilt-ridden siblings succumb to their taboo desires. Michelle, haunted by her faith, gently pushes her baby brother's massive cock inside her, as they both struggle with their conscience. Their father's distant command, "You mustn't move!" echoes in their minds, but innate lubrication soaks their siblings' shafts as they slowly sink down, rubbing their tight, untouched vaginas along the hard cocks. Amidst smeared juices and spent fluids, they collapse into post-coital remorse, praying for absolution from their taboo lust.
