I had never looked at my mother-in-law Yoko with any lustful eyes. After all, she was a good woman, and my wife and I were always grateful for her kindness... But ever since I accidentally saw her naked, the desire to embrace Yoko grew within me. Her bashful, maidenly expression, her smooth white skin, her soft-looking breasts...there was nothing like that in my wife. I could no longer control my reason.
