We've been married for a few years. - I didn't think that not having sex would be so difficult for me, who was still young. - Around that time, my mother came to Tokyo on a trip. - My mother, who I hadn't seen in a while, seemed to be doing well, and my wife and I happily welcomed her in. - A wife invites her mother to take a bath to soothe the fatigue of a long journey. - At that time, I happened to see my mother naked. - Although some parts of my mother's body were crumbling compared to what I had seen when I was a child, she was indescribably voluptuous, and I found myself lusting after her body. - That night, I hugged my wife to let her control my heated crotch, but as expected, she refused, so I made a decision. - The next day, my wife went shopping and my mother asked me about my concerns. - Unable to get shite from my wife, I hugged her, wanting her to do something about my hard erect crotch. - My mother said no, but she gently hugged me and buried her face in my crotch just once, leading me to ejaculate. - However, I decided to unite with my mother because of the erection that wouldn't go away.
