Trapped in a cramped closet, two siblings struggle with their religious guilt and burgeoning lust. Michelle, haunted by her desires, can't help but imagine her brother's massive cock inside her. Her brother, equally tormented, can't resist the temptation of his sister's untouched body. As their father commands them not to move, they can't help but grind against each other, their innate lubrication soaking their semi-clothed forms. Their taboo lust unleashed, they collapse into a heap of spent fluids and post-coital remorse, praying for absolution from their sinful desires.
