BTS sceneswhere females fucks/sucks even though she's not shooting the scene

I remember seeing a scene where Ashley Blue is hanging around in set while they are shooting a scene with other girl, and during a break she decides to jump in and suck off the male "talent". I jus't dont remember where I found it! Anyone has any ideas?
 
Hi guys
I'm looking for a video from a long time now, and I thnik it could be related to this thread, as i kinda think it's fake (but very convincing!).
The video is just with a girl and a cameraman. It start with a discussion about the flat they're in (wich is the pornstar's), they're talking about furniture and stuff in LA, then she start saying that she had never fucked him (as he is part of her crew), then end up with a nice long fuck in the flat. (she even bring him in the bathroom for some pissing action!)
I think I saw this vid a long time ago on redtube, but I can't find it anymore, i'm not sure...

Thanks for the help!
