Under the watchful eyes of their crucifixes, the nuns succumb to their darkest desires. Sister Mary, her once pure lips now wrapped around Mother Superior's clit, sucks eagerly as Sister Elizabeth impales herself on the old nun's fingers. Mother Superior, her voice thick with lust, leads the prayer, 'Our Father, who art in heaven...' They continue, their bodies slick with sweat and sin, their moans of pleasure interspersed with Hail Marys, until they collapse in a heap of spent flesh, their taboo lust sated, their souls forever stained.
