Although the male in this gif is not showing any emotion, I can attest that this implement causes my feet to start dancing, and I am singing a not so merry tune while Cindy is spanking me with it.
It is one of Cindy's favorites, and also great for the back of the legs...
Cindy rarely uses her hand, as it should be my bottom getting the work-out, not her hand!
Cindy has rarely ever spanked me with this intensity
