Excellent shots. So clean and clear, you can just about feel the texture of them lovely soles. I can understand why it keeps driving you crazy. So close, yet so far. But yum, Nice she let's you have access to seeing and photographing them.
Shaking ones? Why were you shaking? he he he he he. Drives you crazy, I know. Well, you did get some nice ones. One of the advantages of taking a lot of shots. But no, I don't think she's naive.
Dude you gotta ask if you can tie her feet up and either tickle or at least pose . Tell her feet only so she will not freak. See what she says ... hot babe with meaty soles, I like.
