The priest's voice echoes through the chamber, "Prove your devotion, my children." Naked, the sisters kneel before him, their small breasts heaving with anticipation. He presents them with a cross and a phallus, symbolizing their choice. With a mix of fear and excitement, they select the latter. The room fills with their soft moans as they take turns sucking and riding the priest's cock, their hymens stretching and popping, marking their irreversible descent into carnal sin.
