In a world where various information is confusing, the number of young people having sex in the wrong way is rapidly increasing! Therefore, the government has enacted a law that says, "Virgin men and women must attend a sex training school, learn about sex, and obtain a sex license before they can have sex." At the training school, students will learn about sex in a classroom, then ride a real man and experience penetration...etc. By learning the basics of sex, they will join the ranks of adults who can share pleasure with each other, rather than just having sex for themselves. Enjoy sex safely with the right knowledge and methods!
