they said in CZ incest is not allowed on video, in USA too but not sure it's really written by law and which law ? the law of the place it was made has to be prooved ...
So it's not so easy I think to fix all parameters if you have a good lawyer !!!
About the sister pissing on each other, well it's also something difficult to classified I guess for a judge. I laugh about it now thinking this Vanessa said to a friend of mine I do just discusting things on my site, but yes pissing on your sister is top clean !!!
