A fashionable and high-spirited woman named Riko works as a shop clerk, serving customers with her G-cup body. However, she has had bad experiences with boyfriends in the past. At a haphazard bar where she was taken by one such boyfriend, she learned about the pleasures of group sex and awakened as a dominant bitch. When she arrived at a circle interview, her eyes sparkled with lust as she looked at the interviewer, indicating her desire to participate in their party. Despite her boyfriend's instructions to use condoms only, it seems that she doesn't intend to follow them at all. The circle members have decided that they won't let such a beautiful woman live up to her reputation; instead, they plan on having multiple rounds of unprotected sex with her.
