I'm Hiroshi. I've been dating my girlfriend for half a year now. Her mother, Rieko, is a single mom who raised her daughter alone and is kind, beautiful, hardworking, and has a calm adult aura... But actually, I have a secret from my girlfriend... I am also in a sexual relationship with her mother, Rieko... Both Rieko and I think this kind of relationship is not good... but we can't stop the urge and the desire to reproduce.
