i`ve been tickling the soles of my sisters feet ever since i was in my early teens and she was 19 or 20 (her ex. was into tickling too i think because he`d always involve me in tickling them when we`d pin her during play-fights).She`s in her early 30`s now and if we`re alone together i`ll still sometimes seize on something she says or does,especially if she`s wearing hose which make her soles ultra ticklish,as an excuse to pin her ankles and tickle her soles for a few minutes until she loses control completely and collapses into fits of tearful laughter.Why waste a pair of available,unbearably ticklish,soles if they`re in your life,lol. 😀
