In a dimly lit chamber, two innocent sisters, bound by faith and fear, face their ultimate test. The priest's stern gaze and the heavy crucifix weigh upon them as he commands, "Prove your devotion." They tremble, knowing what's expected. One by one, they kneel before the altar, lifting their habits to reveal their untouched virginities. The priest's rough hands guide their heads, pushing their mouths onto the hard, forbidden flesh. They gag, tears streaming, but obey, their young bodies betraying them with unwanted arousal.
