Gravure idol ``Ria Yamate'' is said to have the best proportions in the industry. She had a secret. She was having an affair with a producer as his mistress in order to get a job. And her adulterous trip gradually changes from shame to pleasure as the perverted producer restrains her, plays with toys, drinks, etc. She has been trained to ask for a penis by herself in the morning. She is a good woman who accepts all of your sexual desires with a win-win mistress contract.
