SPRD-1148 Mother's first in-the-vagina ejaculation by her son Reiko Fujikawa

A few years into our marriage. I never thought that not having sex could be this painful for someone as young as me. 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, there were parts of her body that had sagged, but she was still quite alluring, and I found myself desiring her body. That night, I clung to my wife, wanting her to help with my heated crotch, but as expected, she refused, and I made a decision. The next day, while my wife went out shopping, I confided in my mother about my troubles. Unable to get relief from my wife, I clung to my mother, begging 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.
