I'm Hiroshi. I've been dating my girlfriend for half a year now. Her mother, Mrs. Kozue, is a single mom who raised her daughter all by herself. She's kind, beautiful, and hardworking, with a calm and mature aura... But actually, I have a secret from my girlfriend... I've also had sex with her mother. Both Kozue and I think this relationship is wrong, but we can't stop our urges...
