Exuding a strangely erotic aura, she is deliberately lured away during the shoot and suddenly forced into lewd acts. Right before the actress Natsuki Ando and the male actor perform an explicit scene together as a provocative display! When trouble involving the actress arises, the female photographer unexpectedly steps in as a replacement model. Changing into a sheer outfit, she opens up about intimate secrets of amateur women's masturbation—something only women can truly discuss. In a highly charged atmosphere, the film takes a shocking turn as it captures the sex life of a working woman.
