ERDM-141 - "Promise me it'll only be once..." I had sex with my wife's mother... 4 hours of immoral relationship

When my wife was hospitalized for childbirth, my mother-in-law forcibly moved to Tokyo from the countryside. It seems like she's worried about her daughter after giving birth and how my life is going. He begins to live alone with his mother-in-law. My mother-in-law changed clothes in front of me, and I was lusting after her so scantily clad and defenseless mother-in-law. The son-in-law ends up having sex with his mother-in-law, but the mother-in-law says, ``What are you talking nonsense about? You're going to be a father. My heart just can't handle it right now. It's just for today...'' and she forgave him physically.
