The female teacher Naoh is serious at school and loved by students and teachers alike, but in reality, she's a perverted masturbator with wild fantasies. Once home, she indulges in masturbation daily while imagining plays with her male colleagues or students. Eventually, these fantasies become real. She gets cornered by the students at her home for continuous internal ejaculation. Furthermore, her colleague teachers join in, resulting in 20 consecutive internal ejaculations!
