In a house of God, forbidden passion blooms between a pious sister and her unworldly brother. As they huddle together in prayer, their hands brush, igniting an electric spark. They steal glances, their hearts racing, as they feel an unholy urge growing. Soon, they're locked in a heated embrace, their hands exploring each other's virgin bodies. The sister guides her brother's trembling fingers to her aching pussy, while he tentatively touches her breasts, their innocence lost in a whirlwind of taboo lust.
