Takashi is an unequaled man who cannot be satisfied without holding his wife Akiko even before going to work at the company. He also has a relationship with his sister-in-law, Yoshiko, who visited him while his wife was away. The next target is Etsuko, a young wife of his co-worker/neighbor. Takashi invites Etsuko's husband to dinner with him and his wife and gets him drunk, drunk enough to make him sleep at his house while he goes to the other house to have sex with Etsuko. What he doesn't know is that Etsuko's husband just pretended to be drunk so that he can be alone with Takashi's wife. Apparently, like their spouses, the two also have an ongoing affair.
