MFT-016 一位漂亮的女学生在“性生活”科目上不及格……！在这所学校里，全校师生都会支持那些不及格的学生。他们在补习课上做爱并达到潮吹！！

In the year 20xx, a subject called “Sex Studies” was introduced in Japanese schools as part of educational reform. Under the philosophy of spreading sexual information to all students without barriers as knowledge and experience, the educational system required students to repeat the year if they did not get a certain score on the exam. Girls who failed were forced to have sex with teachers or students helping them as practical supplementary lessons, exposing themselves to the whole school in embarrassing situations until they passed, and learned what sex is.
