Yes they came from this guys site, mixed in with lots of unrelated stuff (afaik).

He seems to grap pix from all over. The image titles seem to be numbers assigned by the gallery site he uses

So no help there really. The girl at the back in one pic clearly has a photo ID card on a tape around her neck. I 've seen those on other (scandanavian?) pics. Otherwise no clues that I can see. Lots of piles of clothes around the room though, so I wonder how many naked people the camera missed :-)
These sort of odd pix with no context frustrate the hell out of me. After all there are a million zillion pix of naked girls on the web, what gets you going is the 'edge' to the ENF situation. Like wouldn't it be nice to have the whole event in sequence, dressed > undressed, one by one, or however they did it. Apart from anything else I wanna know how you end up with shy girls stripped naked in a room full of folks. (Well, don't we all).
Clearly some of us just went to the wrong college!
