100 million years of evolution prepared a special part of my brain, apparently, that just goes slack-jawed stupid at a sight like this.
Now, I'm not saying this photo is "fine art" - but it's not particularly naughty, either. The reaction is all in my brain. Surely evolution provided for a little voice someplace in my subconscious that's saying, "hey! HEY! check that out! she looks healthy and ready"... So I find this photo to be actually a lot "naughtier" than many of the spreads and unnatural poses one might see in porn.

Lighting is simple: a medium softbox to camera right. Post-work is simple: channel conversion 50% g 50% b, and level adjustment.
