For all the people complaining about or complimenting the "art", you're mistaken either way. It's clearly real porn video frames or photos with effect filters to make them look drawn. I'm not saying it doesn't take some effort to find the images and edit them, but there's no point in critiquing it as if they were originals.
In fact, I was just going to ask who's the actress in the thumbnails because I recognize her from some pron clip I must have seen somewhere... but I found her on nudevista; it's "Foxy Di" for anyone else who was wondering.
So, that also answers your questions about kink content as well: don't expect something that wouldn't usually show up in real porn (regardless of the legalities of various juridictions). At least at this stage of development, the art probably wouldn't portray it.
