I quite like hands and feet. Not quite to fetish levels, but still...
I think I like hands because of their versatility. Hands can do lots of things. (I typed that without thinking what it meant, but I mean it, just not in a sexual way, so stop letting your minds go there. Stop it, right now.)
And as for feet well... I don't know. If a girl has nice feet though, it's kind of like a surprise. It's like, wow, you're a really nice person, and even this bit of you that I've never been able to see because you always wore trainers is also very nice. How lucky am I.
