That’s absolutely not a pornographic photo. It’s an artistic photo (and this is also quite apparent by looking at the others in the series).
If you want to see what a pornographic photo looks like, I’ll show you one.
Oh, fine. Nude photo. Semantics. Sorry.
Well it is a very nice nude photo though.
Since it’s a Playboy photo, I think it’s supposed to be a variation on the rabbit tails that Playboy Bunnies wear.
