The husband goes on a business trip alone, leaving the neighbor's wife living lonely. Yoshioka, who lives next to this wife, is an overly meddlesome busybody. One day, when the wife is bedridden with a cold, he brings her food and takes care of her enthusiastically. After recovering, the wife offers her body as a token of gratitude. Unable to resist temptation, Yoshioka ends up having sex with her in the heat of the moment. However, Yoshioka's overly innocent reaction stimulates the wife's maternal instincts, and she plots to seduce him again the next day. She lures him in wearing a see-through costume, and they end up burning with adulterous passion.
