Under the watchful gaze of a crucifix, two angelic sisters, dressed in modest nightgowns, are ordered by their father to prove their virginity. He produces a thick, veined dildo, a replica of his own cock, and demands they take it. The eldest, trembling, spreads her legs, guiding the massive dildo into her tight, untouched hole. Her sister watches, biting her lip, as the dildo disappears, inch by inch, until it's fully sheathed in her sister's dripping cunt. The father grunts in approval, leaving the sisters to their newfound, forbidden desires.
