I love nylon tickling. My favorite are tan colored (or nude) plain pantyhose - just like Ash appears to be wearing.
Too bad the pics are a little blurry, and that none show her face and her soles in the same pic. I guess you were holding the camera at the same time you tickled her.
Please post some more, but first buy a tripod for your camera so you can reposition the camera to get a better angle and more stable shots.
