Sydney is on my wooden tickle board with her gorgeous feet locked securely in my stocks. I love how soft and sensitive Sydney's feet are, and I'm going to thoroughly enjoy tickling her feet without any mercy!  I use a feather here and there just to help excite the nerve endings in her soles and toes. But the real tickle torment happens when I use my long sturdy fingernails to tickle them. Part way through the scene, I apply baby oil to the bottoms of Sydney's feet to make them even more ticklish. And not only do I continue to use my fingernails, but I also use a couple of scalp massagers to help maximize Sydney's ticklish suffering!
