My boyfriend at the time was my girlfriend's mother, Yuko Shiraki (ALDN-375)

I'm Genta. Married for three years, I finally had my long-awaited son. After his birth, my wife was depressed, and I lost interest in my life. One day, I met my wife's mother, Yuko. Actually, Yuko and I had a past relationship, but my wife and I have broken off all ties. Meeting her again after six years, memories of the past flooded back… The days we sought reconciliation. A mother's longing for her daughter. A husband's anxieties about his wife and child. When these feelings intertwined, we made a decision… a relationship of "having sex with my wife's mother." Experiencing physical pleasure again after six years. I longed for Yuko.
