Rebecca from Live Model Books/Pose Space. Its an artists reference site. If you draw like me, then its perfect, although I reckon half their members never put pencil to paper or brush to canvas! ;-D

I found the photographs a while back and they were all entitled "Shynude". She's one of my fave ever internet ENFs and it's a shame we've only ever uncovered the five photographs of her which I've posted here: https://forum.oneclickchicks.com/album.php?albumid=4452.
