A documentary about four people—a married woman and three amateur middle-aged men—spending a night under one roof to release their sexual desires. Initially tense, the married woman Akari gradually opens up as she spends time with the men, revealing her slightly sadistic nature and confessing her desire to perform fellatio multiple times, something she can't do with her husband in everyday life. In the end, they engage in excited sex culminating in internal ejaculation.
