Chad White, the devout brother, struggles with his faith when Cosima Dunkin, his step-sister, starts seducing him. In the cramped closet, they grapple with their desires, Cosima's breath hitching as she feels Chad's cock stiffen against her. "Shut up and fuck me," she whispers, her pussy already drenched. Chad hesitates, then surrenders, fucking Cosima hard and fast, their bodies slapping together as they seek forgiveness for their taboo lust.
