A devout Mormon teen, taught to suppress her desires, finds herself in a tug-of-war between her faith and her primal urges. When her missionary worker arrives, she's overcome with guilt as she watches him pray, his voice deep and soothing, yet her body responds traitorously. She sneaks into his room, finding him sleeping, his cock tenting the blanket. She can't stop herself, her hands shaking as she pulls out his length, stroking it gently. He wakes, catching her, but she's lost in her lust, her mouth descending onto him. He's rock hard, his cock throbbing as she sucks him, her gag reflex nonexistent. He fucks her mouth, his hips lifting off the bed, his hands gripping her head. She swallows every drop, her chin glistening with his cum, her eyes filled with shame and satisfaction.
