[ENGLISH-SUBTITLE] NDRA-070 I'm Fucking My Girlfriend's Mom Behind My Girlfriend's Ba

My name is Hiroshi. I have been dating her for half a year. Her mother, Rieko, is a gentle, beautiful, hard-working, and calm adult woman who has raised her daughter as a single mother. But actually, I have sex with her mother without telling her ... I and Rieko think that this kind of relationship is not good, but we can't stop each other's desire for reproduction.
