In a classroom after hours, a young ladyboy is initiated into the world of deep throating. Her tutor, a stern man, guides her head down onto his stiffening cock, teaching her the rhythm and pressure to pleasure him. She gags at first, but soon finds a rhythm, her eyes watering as she takes him deeper. He holds her head, thrusting gently, teaching her the art of giving head. The room fills with the sound of wet, sloppy sucking, punctuated by her muffled moans of newfound pleasure.
