She used to post pics on tumblr a while back as 'garbagetreasure', but she seems to have stopped.
Maybe a google image search to find the pics she did?
Okay, a bit more research...
It's a pic, called 'Get Off My Lawn', taken by a deviantart user called Nemo Valkyrja.
She's got some great stuff on there, mainly cosplay.
I found out the scene is from 'Orgy Sex Parties 7' (http://www.cduniverse.com/productinfo.asp?pid=7955362&style=ice). That should help in identifing the other babe.
