Is it a real porno? it looks real to me. The male pornstar looks familiar. However, I know they can cgi anything so this scene could have been computer generator entirely. Earlier in the movie they showed a jpg nude of Janine Lindemuller. I don't believe this is her in this scene or is it? Obviously this would be Janine before the tattoos.
