Posts about public restrooms are rare these days. They used to appear in phone booths and toilets, but now they're seldom seen. One of them had numbers/QR codes written on a toilet seat. I half-jokingly called one, and suddenly heard a ringtone coming from the next stall!!! A picture!? What does this mean!?? I hesitantly opened the door and was seduced by a sexy old woman. Such a lucky, perverted situation actually happened! If we change locations, I don't want to change my mind, so I decided to do it in the bathroom!! Best!! But there were many other numbers written on it…
