Ah, I'm Hiroshi. It's been half a year since we started dating. Her mother, Mrs. Chisato, is a single mom who raised her daughter alone; she's kind, beautiful, hardworking, and has a calm, mature aura... But actually, I've been keeping this secret from my girlfriend... I've also had sex with her mother. Both Mrs. Chisato and I think that this kind of relationship isn't good, but we can't stop our urges and desire for reproduction.
