Ah, my name is Hiroshi. I've been dating her for six months. Her mother, Senri, is a single mother who raised her daughter alone, a kind, beautiful, hardworking, and mature woman with a calm atmosphere... But in fact, I've been keeping a secret from her... I've also been having a sexual relationship with her mother... Both I and Senri think this kind of relationship is not good, but... we can't control our desires and the urge to procreate...
