Inkou Kyoushi no Saimin Seikatsu Shidouroku

Megumi Fujimiya is the object of attention from the boys at her school, viewed as a desirable sex object. She's a pure, innocent high school girl in the prime of her youth, having just started a relationship with her childhood friend, the ace of the baseball team. Then, a mysterious guidance counselor appears, wielding a strange "sexual guidance notebook" that can alter people's perceptions. "Fujimiya... haven't you forgotten that students who have a boyfriend must take 'sexual guidance' as a required subject?" "I'm so sorry... I can't believe I forgot something so important!!" After being shown the notebook and having her perception altered, Megumi is forced to undergo "sexual guidance" in the infirmary, where, under the guidance counselor's instructions, she is subjected to a procedure involving the injection of genetic fluid into her uterus without any contraception—a procedure that doesn't actually exist. Now, we're going to have "real, unprotected reproductive sex"!

The guidance counselor, having obtained a "Life Guidance Handbook that allows you to manipulate others as you please," begins to prey on female students one after another. He sets his sights on Yayoi Tachibana, a second-year student in Class B of the home economics department, the heiress of a Kyoto tea ceremony school, a girl with a gentle demeanor in traditional Japanese clothing, elegant Kyoto dialect, and a well-developed figure that unconsciously arouses men. He licks his lips, plotting to break her hymen, even though she already has a fiancé. I want to have that man's baby... Please give me lots of your children...!
