What's the name of this porn actor?

Great find@claiton !

Looks to me from this:
http://www.xvideos.com/profiles/beckylesabre#_tabVideos,videos-best
Becky Lesabre is the one on the Right most.

And from the page you linked and from this video:
http://www.porn.com/videos/becky-le-sabre-and-jaime-knight-eat-each-others-asses-in-69-7523
Jaime Knight is the one right next to her (second from right).

I can't say this is necessarily a definitive source, but this post seems to agree with those two guesses:

The forums stuff also mentions "Sara" and "Jessica", but it's unclear if those are pseudonames for these two girls, the other 2 girls, or the guards that are manhandling them.

this movie is "Welcome To Prison" (25/29/2006) -
leftmost Becky Lesabre, , rightmost Jaime Knight, + 2 girls in the center.
