This dude Yoshiyuki loves to work out. He also loves sex, cause he's not dead. Now that he's a teacher at an all-girls school, he gets to combine his two favorite things. He decides to give his struggling students some private tuition, AKA, his dick - cause that certainly won't be hard to grasp.
What's better than hypnotizing a girl into having sex with you? Realizing your hypnotization technique didn't work and that she did it with consent. Hah, who's the fool now!
