My wife refused to work at night again today. - I know you're tired, but...at that time, my mother Chiharu, who had been depressed since my father passed away, came to visit us. - I was relieved to see that he seemed to be in good health. - My wife suggested we take a bath to soothe the fatigue of our long journey, and at that time I caught a glimpse of my mother changing clothes. - I had never had any lust for my mother before, but at that moment I was so excited that my erection wouldn't go away. - I thought that I couldn't be a mother, so I tried to push my wife down, but she still rejected me, and my sexual desire had no place to go. - The next day, when my wife went shopping, I asked my mother to relax in the living room. - I showed my mother my unerect penis and begged her that there was nothing I could do because my wife wouldn't do it, but my mother gave up and rubbed it with her hands, sucked my dick, and made me cum. - Chiharu, who can't sleep at night, remembers what happened during the day. - While I was thinking about that little boy, I was thinking about seeing the crotch of someone other than my husband for the first time in years, and what's more, it was my son's hard, erect crotch, and while I was thinking about it, I found myself groping myself and letting out a sigh. - Then a door suddenly opens. - The son, who was already excited, forcibly hugged Chiharu and caressed her, sinking his hot cock deep into his mother...
