Joshi daisei sex uranai

The story

Keiko Yamaguchi (22), a female university student, works part-time as an office clerk at the Hirata Sex Clinic, which has become quite the topic of conversation on TV and in weekly magazines, thanks to its research into pubic hair growth patterns and shapes, sex fortune-telling, and collection of vaginal prints. Her boyfriend, Maki (30), a magazine journalist, introduced her there. This is because he had begged Dr. Hirata to help Keiko, who is frigid and sexually inexperienced, to develop a love for sex.
