Hanah that is. She comes across in her scenes and posts as someone who delivers the goods. I also like the tall blonde type.
If I can' have her, Chelsea Zinn will do nicely. Same reasons, She leaves her partners panting.
Hot Stuff, easy on the eyes and can string sentences together.

Jewels Jade as my number two pick.

Darryl clearly appears to focus on the guy she is with and not the camera. The Jedi-mind-trick option would not be needed. Someday, I hope to experience her myself

Jewels strikes me as one of the porn stars who absolutely LOVES what she is doing. She seems real and appears to have very few, if any, limits to what she is willing to do. On top of that, she is fucking gorgeous and sounds very smart and articulate.

As far as TV/movie stars go, the Aussie Rachel Griffiths would probably be a tremendous fuck!!!

I love her body and the British accent!

It was a hard choice (or thinking about the choice got me hard, lol)

For a pornstar, it was a close call between

Saskia

(see also this shot of the perfect standing cowgirl

and
Harley Davis

Saskia has the most erotic earthy voice I've heard in videos. Great legs.
Harley has incredible eyes and all the right curves.

But Harley wins by the virtue of how incredible she moves while in the K9 position here (see #3)

and see #3 here for similar movements in the Cowgirl position.

She is the epitome of poetry in motion. A work of art. Sensual and erotic.

As for a celebrity? Can you take Saskia's and Harley's special attributes and put them in Elizabeth Mitchell of "Lost" fame? One can only dream, lol!

As with the previous mention of Kate Middleton, now the Duchess of Cambridge, sign me up for her as well!  I think her beauty and the rest of her wonderful qualities are well documented, and the fact that she's a real live princess and future queen of England (not monarch, like the current Queen, but a King's wife is a queen) makes her even hotter, if that's possible.  Bikini shots readily available on the internet.  And if little sister tags along, so much the better.  Either Middleton girl would be amazing, but an fully interactive threesome with them, my, oh my.  And Pippa probably has some wildness in her that she hasn't had to socialize out of herself like big sister because Pippa isn't royalty, she's just a smokin' hot commoner.  Kate was hot enough to attract a future king, a rich and good looking guy who could have his pick of his nation, and whatever they were doing while living together, it convinced William to marry her.  Since he'd had the sad lessons of his mother who wasn't happy in her marriage, I'm betting William made damn sure Kate made him happy before proposing.

Tough one...either Salma Hayak or Savanna Samson
