A studious young coed, eager to impress her elderly professor, finds herself in a compromising position after hours. Her intellectual curiosity piqued, she innocently asks him to explain a complex concept. The professor, however, has other ideas. He guides her hand to his throbbing erection, hidden beneath his tweed trousers. She gasps, but her surprise turns to curiosity as she tentatively wraps her lips around his shaft. He grunts, guiding her head, teaching her the art of oral pleasure in this hard, reality-based lesson.
