A world where "practical sex education" existed, which began as part of measures to combat the declining birthrate.It is a new sex education that teaches sex by actually having sex with a man and a woman who have sex with her baby and get pregnant.In this work, homeroom teacher Otsuki Hibiki calls on students who refuse to attend school and uses their own body to provide direct educational guidance for creampie sex...and carefully teaches them what they feel about a woman's body and how to please them, they actually touch her, insert her and cum inside her, allowing them to experience making babies, and then report that she is pregnant, and the education ends.
