After her divorce, my wife's best friend, Himari, came to stay with us. As soon as the three of us started living together for a limited time, an incident occurred. One day, after a long absence from my wife, I was caught masturbating by Himari. Himari herself had not had sex with her husband for many years and was feeling the urge to do so. At first, she would secretly drink my semen, but she eventually reached her limit. Despite the feelings of guilt and self-blame, our relationship developed. KM Produce Co., Ltd.
