Mahiro, who has returned to her parents' house to say hello to her marriage, goes to report her marriage to Hibiki, a sister who has been close to her for a long time. I'm glad to receive the report ... but Hibiki is really jealous of Mahiro. Hibiki who can't control her intense feelings and puts Mahiro to sleep, restrains her, and devours her body with all her lust. Bondage training, strong ● Face sitting, toy blame, oil blame, strong ● Continuous Ikase ... Mahiro who can not resist eventually falls into a rope in the endless training.
