In the dim light of their shared room, sisters Maria and Isabella huddle together, their hearts pounding with anticipation and guilt. They've heard whispers of a ritual, a way to verify their purity without the priest's judgement. Clad in their nightgowns, they follow the steps, their breath hitching as they press their virginities against their brother's cock, now tented beneath his night pants. The friction, the forbidden touch, ignites a fire within them. They rub, they lick, they take him in their mouths, their bodies betraying their pious upbringing with every wet, wanton motion.
