You can't go wrong with the rich curvaceousness, spectacular geometry, intricate texture detail and amazingly varied colour of the soles of feet -- AND, of course, the feral smelliness. It's nudity and sexual attraction on a whole other scale. The scale of the hidden and the intimate, but also the carelessly ignored. It's an area that society subliminally says you shouldn't be interested in. This only adds to the allure. And there is a LOT of allure for people that feel it. People like us. In my opinion, this is the BEST fetish you can have!
