A plump-buttocked and busty office lady, Rio, with a body that has an extreme sex appeal. Even today, she attracts the men at her workplace in a tight suit without realizing it. She is courted by her senior, Saito, and taken to a hotel, and while she is confused, she is taken advantage of and has sex. Furthermore, rumors spread that she is a "slut"... Colleagues in the office who heard the rumors attack Rio, who is working overtime, and have a gangbang. This is the result of a woman with a personality that she can't refuse when asked for having been given an overly erotic body by heaven.
