Kana, a wife who is not pregnant and is not blessed with children, consults with Kawamura, an old doctor who has been with her since she was little. Kawamura, who was pondering his feelings, proposed a forbidden infertility treatment, "face licking hormone improvement treatment," which was passed down from generation to generation while hesitating. I wondered if I would get treatment by pushing my husband's opposition, but the treatment is not limited to licking my face insidiously, but the obsceneness escalate, such as caressing the whole body of Kana. Kawamura relentlessly seeks Kana's body as if possessed, and inserts raw material into Kana's vagina for further hormone improvement.
