There was a certain man, an all-girls school art lecturer.
One day, he came across Tomoko, a student who was being bullied, and saved her from her predicament. However, this very event triggered his innermost sadistic desires. Suddenly, he could no longer hold back, and forced himself upon her.
To our protagonist who had awakened to his sadistic desires, Tomoko proposed that he sexually train one of her classmates, Yazawa Mizue, a pure girl, ignorant of the ways of the world.
While being aware that Tomoko was hiding something, the protagonist decided to play along with her plan. Could he become such an individual that could rule others into submission? Not out of simple, mere lust, he earnestly wanted to find the answer to that very question.
Will he really be able to rule over the heroines as if they were his own possession, or else, will he end up as nothing more than Tomoko’s puppet?
