Rui, who has been interested in bondage for a long time, contacted an SM circle through SNS. She will be subjected to her experience bondage at the studio, and will take her best friend Mamiko who she dislikes, but this circle was an extremely dangerous criminal group. In front of her bound Rui, Mamiko was also invited to try it. In front of Mamiko, who was lightly tied up, Rui, who was drunk by her aphrodisiac and became strange, was made to take off her clothes by her men and torture her for pleasure. Mamiko feels something strange at the sight, but it's too late...
