A manual for the female body that explores women's sexuality in earnest. Haruka, 25, an amateur office worker, candidly reveals her embarrassing sexual worries during the interview. She doesn't know the good points of sex, and applied because she thinks AV actors are good at it. The woman, who has had relationships with women, says she doesn't moan like in AVs, and wants to try it. While taking nude photos, her inverted nipples are stimulated and she becomes out of breath. She says that she usually masturbates with women, so she demonstrates masturbation, lifting her hips and ascending to heaven. When he thrusts his penis into her quickly, she says, "That's not good...", but when he focuses on her, she climaxes. She moans and orgasms repeatedly in cowgirl and doggy style positions. She has sex in the bath, and her loud moans echo through the bathroom.
