I don't think it's Jana Miartusova... this girls nose looks a bit wider and also the gallery the pic I posted is from was hardcore (she did anal). Jana Miartusova is all lez and soft core I think.
I still think it does look like Jana, however you are right, it can't be here if that pic is from a hardcore scene. She has done 1 B/G for bigmouthfulls though. wish she would do more!
