Eri Kuramoto just turned 60 last month. Eri has a strong sexual desire and has enjoyed sex quite frequently since she was young. She still has sex with her husband two to three times a week, but recently her husband's sex has become monotonous and she is not satisfied. Feeling sorry for Eri, who is frustrated and wants to have more exciting sex, her husband suggested that she appear in an adult video. Eri can't help but expect exciting sex from the male actor.
