I propped up her feet over the toy box with her ankles crossed. Then I peeled her socks off and tickled her soft white soles with my fingers and a few different brushes while she begged me to stop. I turned it up a notch when I put on a vibrating glove and stroked her feet, she wasn't expecting that. she was going crazy when I straddled her ankles and used my fingers to take her past her limit.
