My life became increasingly difficult when my wife passed away and I became single. I was desperate and everything was getting worse. At that time, my son came to my house with his wife, Kasumi. Kasumi, who could not see my struggles, tidied up the room during her stay. I was very happy and felt like I smiled for the first time in a long while. However, when I looked at her, I realized that the sexual desire I was gradually losing in my body was reawakening. This urge was uncontrollable.
