lol appreciate the bump :P

if it helps, the video is of a "couple" going into some sort of clinic where they get masturbated in front of each other by the "clinic staff", until they ultimately fuck each other while the staff just kick back and watch. hundred percent there's a whole series of this or something, just need to find more or get more details. I've tried looking through the sites advertised in teh screenshots, but don't speak asian so didn't get very far...
