Outdoor theme. I'm stretching the definition of ENF to include shy ladies and a few with unknown reactions to being photographed nude. My preference, like yours I assume, is to see the embarrassment in their expressions and body language, but it's easy to assume that any woman who doesn't pose for nude pix has a degree of embarrassment knowing these are on the Internet. So if you see anyone you know, make sure to tell her and then report her reaction back to the rest of us.
