Porn Stars in Game of Thrones Season 4

This is the first attempt of HBO casting actual current porn starts for Game of Thrones, after Sibel Kekilli, who is an ex-porn star and plays Tyrion's prostitute/pretend girlfriend. The new porn actresses that have been cast are Jessica Jensen, Samantha Bentley and Aeryn Walker. I personally have never in my life heard of these women. I do not know how is that going to work out, since acting in porn is not always very good. Funny thing is I know some people who watch Game of Thrones only because of the sex scenes and do not want to read the book series after I told them that the books have less sex and more epic... Idiots.
