About 14 years ago, my wife's sister came from about 6 hours away to visit us for a weekend. It was just her and her 14-month old daughter. That first night I went upstairs with her to help set up the portable crib in the guest room. We had been talking about feet downstairs, about them needing pedicures, etc. and I don't know why but I came out and said "Aren't you deathly ticklish on your feet? I know your sister (my wife) is." She said "I don't know, I don't think so. I know I don't like anyone touching my feet."
I said "Sit down, let's see." And she sat in a chair and slipped off her boot but let me take off her black sock, exposing her size 7 gorgeous foot. I raised her leg and began running my fingertips over her soles. She didn't respond. After about a minute I put her foot down and she said "Oh well" but didn't put her sock back on. We finished putting up the bed. Just as we were about to go back downstairs I said "Let me try one more time." She sat back down and raised her leg towards me. This time I used more fingernails and also went longer. After a couple of minutes she gave a low laugh and her foot twitched and she said "Now you're starting to get something." I tickled her foot for about 5 minutes and while she never laughed hysterically, it was obvious that she felt it and could have really cut loose.
There was nothing sexual, and we went back downstairs. I tickled her feet several more times over the years.
