In the near future, Japan has become an aging society with a very low birth rate, and the number of children has dropped dramatically. This has led to the establishment of a sex education committee. Students who are not interested in sex are also a problem, so the "Creampie Duty Law" is enacted to encourage child-making! Girls selected as model cases will become officially recognized sexual outlets as part of sex education, to teach them the pleasure of creampies! They will take on the sexual desires of students and male teachers, and have sex with them without a break, morning, afternoon, or after school, until they impregnate them! A school sex life filled with intense creampie sex!
