In a hidden chamber, pious sisters gather, their faces flushed with anticipation and shame. They've been told to verify their purity by their austere father, a task they undertake with trembling hands and hurried whispers. One by one, they kneel before the makeshift altar, lifting their skirts to reveal their untouched flesh. The room fills with the soft rustle of fabric and the hushed prayers of the initiates, as they perform the sacred ritual, guided by the stern voice of their father echoing from a hidden speaker.
