MIST-471 Dangerous Day Hit Directly!! After-School Sex Education for Starting a Family Hibiki Otsuki
In a world where “practical sex education” was introduced as part of efforts to address the declining birthrate, students learn about sex through real-life experience. This new approach teaches them by having a man and a woman conceive a child, allowing them to understand intimacy in a hands-on way. In this story, homeroom teacher Hibiki Otsuki calls in students who have been refusing to attend school and gives direct guidance using her own body. She carefully teaches them what brings a woman pleasure and how to make her happy, allowing them to touch and experience intimacy firsthand as part of the lesson. The education ends once she reports that she has become pregnant.
