She has very nice feet and it looks like they are very ticklish too, thanks for posting the pics. I had a girlfriend who would put her feet in my lap and let me take her shoes and socks off and tickle her feet. She was more ticklish on one foot than the other and when I tickled that foot her toes would curl up and her sole would wrinkle. She wasn't ticklish enough to first start giggling and then start laughing but when I found a real ticklish spot and worked on it she would gently bite down on her upper lip and whimper slightly. She said she had to really focus her mind on something else to keep from losing it when I was tickling her where she had a weak spot.
