A brother and sister, bound by religious constraints, find solace in each other's company. In a cramped closet, they maintain their virtue by masturbating together, their innate lubrication soaking their siblings' cocks. As they slowly sink down, rubbing their tight, untouched vaginas along the hard shafts, they're consumed by taboo lust, collapsing into post-coital remorse amidst smeared juices and spent fluids, praying for absolution from their incestuous sins.
