I agree with the chick that likes the hollow at the top on the thigh, That is my favorite erogenous zone. That's why I always wear stockings, and not pantyhose, because I love to be kissed there during foreplay.

I Know a guy that loves the front of my knees, when I cross my legs,when I am wearing ultra sheer stockings and a garter belt. He says they are so tight and shiny he could lick them, and he does, I really don't see any harm in it..
