This slave behaved well all day, therefore We decided to give him a treat that you're surely envious of. We're going to use Our sharp stiletto nails inside his urethra. If you are experienced with nails sounding, you know how the erection affects the sounding process. If the slave gets too hard, We're going to punch his testicles into submission. Before We begin, We ask the slave which nails he believes will be more painful and We compare Our long sharp fingernails. First, I insert the pinky fingernail of My left hand, which is pretty shiny and curved. The nail goes all the way in, to Our satisfaction.
