Darth, how long could you go for if she didn't take her socks off?
LOL. Well to be honest. I'm not a "pure" foot fetishist in that I do not require feet to be part of a sexual experience. Someone who really does have a fetish actually has to have the object of their fetish be a part of sex for them to enjoy it.
For me this is not the case. Sure, sometimes it is. Sometimes not. Like I said earlier, my biggest turn on is seeing her enjoying whatever we are doing. Feet, while a big turn on for me, is no bigger than her breasts, arse or just being naked in general.
