For as long as I can remember, I had always wanted to tickle women's feet. Never girls my age, but older girls who were in their late teens,20',30's, ect. ( I think I must have been about 7 when first discovering it).
I remember my first experience of my babysitter who must have been about 18 who was laying down watching t.v. and I crawled on to the back of her legs and started tickling her barefeet. She wasn't at very ticklish but her feet did respond to my exploring fingers by her flexing her feet back and forth.
She never told me to stop and actually said it felt good.
The first time that I knew there was something very profound to me about tickling though, was before my the experience with my babysitter
and that was when I heard my two older cousins (both female) talking about the movie "Creature from the Black Lagoon" and how the Creature tickles the feet of a woman swimming in the lagoon.
Some years later when the movie was on t.v. again, I remember literally trembling in anticipation when the woman went in for a swim and when she was treading water the Creature tickled the actress' foot twice.
I couldn not believe what I saw and for years thought I was the only person in the world who wanted to tickle women's feet.
