Now in her third year of marriage at the age of 28, Yukiko-san (alias), a married woman, has been traumatized by sexual bullying from a group of male classmates during her student days, making her dislike men and marry her husband as a virgin. Until then, she had never even masturbated, believing that sex was an act only permitted between husband and wife. She had lived her life trying to stay away from anything related to sex and thus had no knowledge about marital relations. She always obediently accepted whatever her husband demanded. However... she realized after marriage that her husband did not have normal sexual preferences. His demands gradually escalated, and before long, their life was no longer like that of a typical married couple.
