Ayako, who has an ordinary man as her husband, is troubled by her lack of sex. Every day she satisfies her libido with masturbation after her husband goes to bed. One day, Ayako sees a "female training blog" and admires the women who are being trained there. She was so excited that Ayako sent an e-mail to the administrator of the blog, saying, "Please train me." On the day of her training, Ayako, who boils her masochistic blood while being tied up, beaten, and blamed, gets drunk with the pleasure of her masochism.
