Mizuki is a teacher who is extremely passionate about her profession. Her greatest joy is watching her students grow up. Adolescence is also the most sensitive age, and Mizuki has a "special" educational method so that when they graduate, all of her students become good students. And that method is, soliciting sex from your student! That's right, so that the students wouldn't be too concerned about sex anymore, Mizuki decided to satisfy them sexually. In addition, if students study hard and their scores improve, she will also "reward" those students. And since then, Mizuki's students have studied harder and everyone's scores have improved. Because she knew the students' fathers were very curious about their children's progress, Mizuki decided to let the students' fathers join one of her "special classes" so they could better understand her teaching methods. ..
