It appears that her first name is Teresa; the photo was taken by Tristan Savatier at the 2013 Burning Man gathering. They are natural breasts, but Savatier was using a fisheye lens.
I suspect that is about all I could find about this lovely lady. What happens at Burning Man stays at Burning Man, except for the photos. If you want to know more, ask MunchWolf.
Mod edit: you beat me to it PB... I recall the Burning Man info too, but not her name. I'll mark it solved and if we learn more, we can update. Thanks!
