Who is she????

Her name is/was Katlyn aka Katlyn Davis - a (semi-professional) photo model, not a pornstar (and she most likely retired a long time ago).

In the upper left corner of OPs picture, you can spot the url of a website called Digital Willy. When you search for OPs picture via tineye, one of the results is the following webpage from Digital Willy:
http://www.digitalwilly.com/workshops.html

When you scroll down, you can spot OPs picture as a thumbnail for number "282 - 8/23/9 - Metuchen":
http://www.digitalwilly.com/katlyn/t2_katwindow.jpg

When you look at the url of the picture, you can find her first name: Katlyn. Now, when you search via google for her first name in connection with the website Digital Willy, you'll find several results that point you to another website called Glamour101, run by photographer Greg Price. For examples:
https://www.glamour101.com/models.html
https://www.glamour101.com/update-281.html

On both pages, you can find a link to a page for Katlyn:
https://www.glamour101.com/katlyn.html

As you can see, the page was "removed by request of model". But you can use the wayback machine to see 3 different archived versions of the page from August 2009, October 2011, and January 2012:

https://web.archive.org/web/20120101073933/https://www.glamour101.com/katlyn.html (archived)

As you can see, her full (model) name is/was Katlyn Davis. And you can also spot OPs picture on the second and third archived page. And if you click around, you can find a few more pics of her here:
https://web.archive.org/web/20110713112133/http://www.digitalwilly.com/katlyn.html

She also had an account on ModelMayhem, but it's long gone - which most likely means she's not active as a model anymore. When you read around, you can find out that she modelled besides her day job, and she "vanished" at the end of 2011.

PS: If you want to see other photos with her by a different photographer, look at the following gallery on flickr with pics by Daniel Horsey:
