Any way you do this, I'd love it, cos I adore feet, and worshiping them!
I was thinking a denial shoot might be one where I get to view all the pics of your sexy shoes, perhaps other things that at one time or another covered your sexy feet, like socks, stockings, etc. Maybe worn workout shoes, so they are all scented nicely with your sweat! But not allowed to actually see your feet in this shoot!
Or a shoot where it's JUST your feet and no other part of your beautiful body.
Just some initial thoughts.
