Most enthusiastic/sliuttiest current pornstars?

This matter of who's the best looking woman in porn, now or historically, is all very well, but I find enthusiasm is a more stimulating value than simple beauty.
Easier to assess, too – male tastes differ so much – for example, I confess I've never been as hot for blondes as brunettes, but if you're big on blades, why not? Besides, I like a nasty blonde now and than.
But brunettes, with a tan or porcelain white... but especially brunettes who leave their underwear at home, stroke the front of a stranger's trousers, talk shockingly dirty, and like to willingly do things that look at best uncomfortable and possibly painful or downright degrading.
Names, descriptions and startling proclivities, please.
