A body easily violated… The fact that she was being humiliated led her father-in-law to force her to continue being violated. Misaki Nanami, a sweating yoga instructor's wife, IPX-763

Nanami, initially reluctant to live with her father-in-law, only agrees because it allows her to open her dream private yoga school. One day, during a private class, she is assaulted by a male client. Her father-in-law, seeing this, misinterprets it as infidelity and later forces himself on her. Once freed, he becomes indifferent to the future abuses. Nanami gradually becomes controlled by her father-in-law, even engaging in sexual relations with him when her husband is present.
