I could never understand this "licking one other's feet" thing- like.. how is that supposed to be hot? All you're licking there is only dead cells, sweat and I'm sure some germs as well. I do agree people look kinda hotter barefeet, but this just makes me nauseous... That's just my view on it, anyway.
The attraction and love/lust for feet is probably one of the hardest things to explain...for me at least. I don't even try really. Just glad I have friends in low places who keep my addiction sated.
