Edith is face down with her bare feet exposed for some tickle . I start off using my fingers and some oil, slowly dragging my fingers up and down her soles. In between and on top of her toes is a particularly sensitive spot. I surprise her with the hairbrush and ratchet up the intensity a bit. What she absolutely hates is the electric toothbrush, especially around her toes. When I use the electric toothbrush between her toes she tries to break free to get away. I go back and forth between the slower finger tickling and more aggressive brush tickling to drive Edith crazy.
