Recently, intelligent girls who can study well are not only interested in mathematics and English but also eager to learn H-studies. Such a girl will showcase the H-knowledge she has acquired for everyone. In sex education that arouses men, she exposes her own erotic body and performs masturbation. In sex education that makes men feel good, she uses the techniques she has learned to tease and caress the man's sensitive spots. Finally, in sex education where both men and women can feel good, they use each other's genitals to experience pleasure together.
