Feet are complicated things. I’m sure most non-kinky people lump all feet related activity into the single category of fetishizing unusual body parts. But those of us with slightly more discerning (or depraved) palettes know there’s a little more to it than that.
A masochist might love ball busting, trampling or general kicking. He (or she) enjoys feet for the options they give a sadist to inflict serious pain in a very controlled and personal way. Alternatively, a submissive may enjoy the D/s aspects of scent, worship and service. Feet have maintenance requirements (cleaning, massage, nail care, etc.) which make them ideal for submissive rituals. Finally, a foot fetishist loves feet as a thing of beauty in themselves. They enjoy looking at them and caressing them, with no need of a D/s or SM dynamic.
When it comes to pornography involving feet, there’s often an overlap between these categories. The same image can be interpreted in different ways depending on the proclivities of the viewer. I think the shot below is a good case in point, where all three alternatives are feasible. There’s physical proximity for the fetishist, scent and subservience for the submission, and painful pressure for the masochist. Personally I’d say it looks slightly more masochistic than anything else, but beauty (and porn) is in the eye of the beholder.
I found this on the Femdom Style Counsel tumblr site. It’s originally from Princess Kali’s site.
