My name is Takuya. I'm a university student. I've been dating my girlfriend Ako for almost six months now. By the way, her family is a single-parent household, and has been for many years... Her mother, Reiko (45), is a single mother who has raised her on her own. ...So, you see. Actually, yes. I've been having a physical relationship with her mother, Reiko, without telling my girlfriend Ako...
