In a cramped closet, siblings defy their religious upbringing. Clothed yet exposed, they battle guilt. Michelle, haunted, pushes her brother's huge cock inside her. They move slowly, her tightness enveloping him. Their father's voice echoes, "You mustn't move!" yet innate lubrication soaks them. They collapse in post-coital remorse, praying for redemption from their taboo lust.
