KSBJ-059 Widow's mother-in-law who seduces her son-in-law Maiko Kashiwagi

I'm a 38-year-old office worker. My mother-in-law came to help me with my wife's childbirth. My mother-in-law is 55 years old and is now a widow. I got a young wife, so I'm close to my age and I'm getting better. I never thought I would be like that with my mother-in-law while my wife was in the hospital. My mother-in-law was also lonely. Though I thought it was bad for my wife, I was absorbed in the body of her lustrous and plump mother-in-law.
