I wanted to know something about the dvd's that pornsites like bangbros, brazzers, realitykings, naughtyamerica, etc release. Are the scenes in the dvds just like compilations that they filmed earlier and were released on their site? cause thats what I think it is but I don't know, and I always wondered if the dvd scenes were shot for that dvd or they used previously filmed scenes or what. Anyone know?.
