Nene is a newly appointed female teacher at a certain school. She was a talented tennis player who was the queen of the intercollegiate tennis tournament when she was a student. She becomes the advisor of the tennis club as she wished, but standing in her way is Muto, a student who has more power than the teachers. One day, she is raped by Muto. From that day on, Muto takes control of the tennis club, and the days of shame for Nene, a female teacher who has become a sex slave to the devilish students, have begun.
