Riko, a fashionable shop assistant with a G-cup body, is a high-spec beauty who usually works in customer service. However, her boyfriend was bad. She was taken to a happening bar and taught the pleasures of being gangbanged by multiple men, awakening as a masochistic bitch. When she came to the circle interview, she looked at the circle staff with glazed eyes and conveyed her intention to participate in the party. Although she said she was told by her boyfriend, she had no intention of obediently following his instruction to wear a condom. Such a good woman would never do as she was told. The circle decided to break the contract with her boyfriend and have raw sex with multiple men.
