The country was suffering from a serious population decline and an aging society. If people could learn about the wonderfulness of "creampie" and "impregnation," it would lead to a decrease in the population... A model school that is a pioneer in the country introduces creampie training. (The girl is chosen to impregnate and suddenly begins to insert without foreplay.) Students, teachers, and even adults with no experience of creampies compete to impregnate. (Real sperm, Suzune Ichinose retirement work) *There are no performers under the age of 18 in this work.
