I highly doubt she's ever done dp, but as far as anal goes, she's been anally fingered in a couple of times and in a movie with jules jordan, she had a whole toy shoved up her ass. It was soooo hot.
I found Karina Kay at this website for "Anal Cum Junkies", but if you read the description it seems vague about whether she has, or hasn't done anal (other than fingers, toys, or things other than some dude's cock) yet. Here's the link:

And here's the description of her episode:
"The Cum Junky: Karina Kay
Karina is as hot as they come. She’s is what they call the "total package" On top of being amazingly hot she loves the cock, which we were eager to provide. I have to tell you her mouth is like a vacuum and her pussy is outta control too. Her ass is just another story but yeah she lapped up all that cum too which is very respectable
What the full video of this cum guzzler getting slammed."
The vague part I refer to is the "her ass is another story, but..." seems like maybe she didn't go the full way to be what the website advertises - or does anyone have the video to let us know for sure?
