After school, Imai came to the staff room. Her relationship with her homeroom teacher has crossed the line. "Teacher, please punish me again today." She is tied up in her underwear in the corner of the gym storeroom, and writhes in pleasure as her whole body is caressed. Imai tries to suppress her voice so that no one notices. She is taken by surprise and her nipples are stimulated, and she instantly reaches ecstasy. After that, they move to a hotel and play again. She is unable to move, and is strangled in the missionary position and is baptized with an irama, and she moans and cums over and over again. Their extraordinary relationship, which has become their daily routine, becomes even more exciting. Later, Imai, who had poor results in swimming, is punished in the bath of a love hotel. The teacher, knowing that her groin is extremely weak, focuses on her with his foam-covered hands. Seeing Imai screaming and writhing in pleasure and tickling, the teacher's huge dick is about to explode. He forces a soap play and splashes a lot of sperm all over! A secret after-school extracurricular lesson between a student and a teacher that no one can know about.
