Dear Stepmom, I, I Like You Better Than My Wife... Mirei Fujisaki

My wife and I visited her parents' home. To relieve the fatigue from the long trip, they suggested we take a bath. While bathing, I realized there was no soap and asked my wife to get it, but instead my mother-in-law brought it and offered to wash my back. As she washed my back, I confessed that my wife and I weren't having sex. Then, for some reason, my mother-in-law gently grabbed my crotch and said, 'I'm sorry, my daughter,' and brought me to a pleasurable climax. Unable to contain myself, I crept into her futon late that night. The next day, after talking with my wife, I lusted after my mother-in-law's buttocks and started making advances. I got carried away and my wife found out. I managed to calm her down and avoid divorce. After that, my relationship with my wife improved, including our sex life, but I couldn't forget my mother-in-law's body. She too was restless with her unsatisfied desires, and once my wife decided to go on a trip, I found myself saying I wanted to see my mother-in-law...
