A few years into our marriage, I never thought that not having sex would be so painful. Just then, my mother came to Tokyo on a trip. My mother, whom I hadn't seen in a while, seemed energetic, and both my wife and I happily welcomed her. To help my mother recover from her long journey, my wife invited her to take a bath. At that moment, I accidentally saw my mother naked. Compared to when I was a child, some parts of her body had sagged, but she still looked seductive, and I found myself lusting after my mother's body. That night, I hugged my wife, wanting her to relieve my heated crotch, but as expected, she refused, so I made a decision. The next day, while my wife was out shopping, I confided in my mother about my troubles. Unable to get relief from my wife, I hugged my mother, asking her to do something about my stiffly erect crotch. My mother said no, but as she gently embraced me, she said just this once and buried her face in my crotch, guiding me to release. However, the erection that wouldn't subside even after ejaculating led me to decide to unite with my mother.
