My wife's adorable size 7's are feather ticklish. At first she can ignore it but as I run it between her toes and all around them it's light the flood gates open and just dragging the tip of the stiff feather from her heal to toes gets her belly laughing. It's really sexy and cute!
LOL Dam near does count! I've used Klenex on my wife and my red sable artist paint brush is killer on her. Heck, in our 22 years together I have used countless implements to illicit her sweet giggles.
