My wife's sister Aoi came to stay at our house. After eating, Aoi, who had put up with the urge to urinate because his wife let him go to the toilet first, ended up peeing. Something went wrong from there, and Aoi straddled me while I was cleaning the leaked urine and poured urine on my head. From that moment on, a night of hell (heaven?) began, covered in urination and spit while stealing my wife's eyes. Since when did Aoi see through my M nature?
