Reason why feet is a femdom thing has to be with, being under a woman feet, she can make you cum with only her feet? The smell of her feet makes you insane even? It's just levels of how low you are in submission or such? I only like feet for the domineering part. Feet itself looks slightly better than a mite, or a bit more, but you get by drift!
Edit: some people may also like the looks of feet I dont know, I personally just like the dominating part of it, still has nothing to do with androgyny!
But you all do you
