Overview

Nanami's wife, Nanami, was initially reluctant to live with her father-in-law, but she agrees to the idea of starting her dream private YOGA school at her parents' home. One day, Nanami's father-in-law witnessed Nanami being attacked and raped by a male customer during her private lesson, and misunderstood that Nanami was cheating on her, so he coerced her. Once his father-in-law was released, he continued to violate her at every opportunity. Nanami's body and mind were gradually controlled by her father-in-law, and she began to have physical relations with him even when her husband was present.
