拐 ～カドワカシ～

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.
