The weight of their faith presses down on them, but the siblings can't resist the pull of forbidden fruit. Hidden away in the sacristy, they steal moments of intimacy, their hands exploring each other's bodies with a hunger they can't suppress. The girl's breath hitches as she feels her brother's fingers inside her for the first time, her body arching into his touch. He swells with pride and desire, his own needs growing urgent. They stumble through their first time, their inexperience evident in every hesitant movement, but their passion is undeniable. They cling to each other, their bodies slick with sweat and sin, their hearts pounding with fear and exhilaration.
