Mariru Amamiya, the demure student, gets an unexpected lesson in pleasure from her older, authoritative teacher. He commands her to suck his cock, and she complies, her inexperienced mouth taking in his girth. He guides her head, his groans of pleasure filling the room as she learns to pleasure him. The teacher then bends her over his desk, her uniform skirt flipped up, revealing her naked pussy. He plunges into her, fucking her hard and deep, her small body quivering with each thrust. He finishes with a sticky creampie, their taboo encounter leaving Mariru breathless and wanting more.
