A housewife and up-and-coming investigative journalist, Bunko's debut work on sexual abuse in a welfare facility became a hit, leading her to start working on the second installment. One day, Miyazaki, a student she had interviewed for her previous book, visited her after a long time… Having been feeling unwell for several days, Bunko succumbed to sudden sleepiness in front of Miyazaki and passed out. Miyazaki's response was to strip her naked, lick her all over, and insert his penis. Bunko later realized that the helper she recently hired had been giving her small doses of sleeping pills every day. All of this was orchestrated by people who held a grudge against her debut work. Suddenly appearing was a man named Oshima, and together with Miyazaki, they continued to humiliate Bunko… Initially, she resisted, but eventually, her rationality crumbled, and she began to seek pleasure on her own, even urinating uncontrollably.
