In a private, intense session, a Japanese amateur surrenders to her teacher's anal training. Imprisoned in handcuffs, she's made to accept a large butt plug, her tight ass resisting before giving way. Her teacher stimulates her clit with a buzzing toy, her wetness increasing as she's pushed towards climax. She struggles, but her teacher demands her full submission, her body trembling with pleasure and shame as she's broken in for her new role.
