Chiaki is a spectacularly busty 48-year-old wife who has been married for 25 years and has a 17-year-old son. Her marriage has become almost completely sexless. Masturbating alone cannot satisfy her pent-up desire or fill the loneliness of no longer being seen as a woman, so she decides to appear in porn. This documentary follows a married woman seeking through sex the emotional fulfillment she can no longer find at home.
