I was at a 'Happening Bar' in Tokyo years ago with a good friend and ended up sitting in a circular seating area with a hot af JAV girl (sorry, can't remember name but I recognised her straight away). Her and her friend were blowing the 2 guys they were with and my friend and I ended up going into a small area next door that was closed off by a curtain to enjoy our time. The kicker was she kept poking her head through the curtain to watch what we were doing. Stupid me never did think to invite her in.
