After school, Imai went to the staff room. Her relationship with her homeroom teacher crossed the line. "Teacher, please take care of me today." Restrained in a corner of the gym storage room, she was caressed to the point of breathlessness while wearing only her underwear. She suppressed her cries, enjoying the pleasure of having her nipples played with. Suddenly attacked, she instantly reached orgasm. Afterwards, they moved to a hotel and continued the bondage game. While unable to move, she was choked and subjected to the missionary position and oral sex, which aroused her extreme excitement. The unusual relationship in their daily lives was even more exciting. A few days later, Imai was punished for her poor swimming performance in the bathroom of a love hotel. The teacher knew she had a sensitive groin, so he used a bubble hand to target her. Seeing Imai screaming and struggling from pleasure and pain, the teacher's penis was about to explode. They engaged in a bubble game and ejaculated profusely! After-school tutoring between student and teacher, a secret that could not be told to anyone.
