As far as choosing between bare feet or nylon clad, I can only say there is nothing like the feel of a exposed soft female foot against my skin. In another life I had a girl friend who loved having her bare feet tickled softly with a feather, which drove her crazy! Despite this, she would always allow me to slowly suck a dose of whip cream off her tender toes thereby driving her more insane. Of course, while sucking her delicious toes I would always lightly scratch her soles just above the heel, which always sent her over the wall.
