A former gravure idol who once appeared in TV and magazines, Ai has had diverse experiences, including sexual encounters with comedians and foreign talents. Unsatisfied with sex only once or twice a month with her husband, she fell into a routine of masturbation and cheating. Now, she takes on an extreme challenge, exposing the deepest parts of her vagina in wild new acts. Always fond of being watched, she began filming simply saying, "It makes me feel more beautiful." Despite living an ordinary housewife's life, she can't contain her urges and dives into fresh sexual adventures—documenting an utterly shameless day in full detail. This is a raw, real portrayal of her bold new endeavor.
