In my personal opinion, this is art, and it's undeniably pretty dang good. It's also absolutely NSFW. Butt... excuse me... but... is it "porn"? That's a harder question to answer. In my personal opinion, regardless of how you want to define "porn," erotic art crosses a line and becomes definitely, unacceptably obscene when it depicts real people having real intercourse; not even because it's "porn" at that point, but because at that point it's literally a form of "public prostitution." And I personally intuitively feel there's something uniquely bad for the human brain/mind/spirit/soul about that. I don't think erotic renaissance statues, for example, really have exactly the same negative effect on us as actual video footage of people actually copulating. I don't even think it has the same effect when they are merely pretending to copulate and not even really doing it, like in a pg-13 movie. I don't know why... like I said... just something I deeply intuit.
