Haunted by religious guilt, two siblings find solace in each other's arms, fucking their way through their taboos. In the cramped closet, they surrender to their desires, the sister's tight, untouched pussy enveloping her brother's massive cock. As they move in rhythm, their religious upbringing fades, replaced by primal urges. They collapse in post-coital remorse, praying for forgiveness amidst smeared juices and spent fluids.
