Due to the educational reform, dirty talk has become a new compulsory subject, and the three teachers who have been appointed as top teachers are Kanhata, Mizuno, and Nikaido. As the strongest dirty talkers in history, these lewd teachers use words in a lewd atmosphere on a daily basis! They love dirty talk, and the more dirty talk they say, the more lively they become, and they start to get excited while saying it themselves! These sadistic teachers toy with the school's masochistic men in a special class!
