Having a good pair of high heels is always a must if you want to be a Mistress slaves will remember. But when you combine them with a platform, laces, shiny patent leather, and an angry Mistress, you will probably regret every moment under that board. The soles are not smooth at all, instead, they have a painful pattern with many tiny waves made out of hard rubber: perfect for an effective grip while tearing away your ballsack! I understand how scared you may be when a pair of heels are trampling your genitals... A heel might eventually hit a testicle too hard, or I may break your urethra if I put too much weight as it can be easily damaged if your cock keeps being so excited the whole time. I think the best part of everything is well-landed kicks and bruises slowly appearing all over your skin. I would love also to see blue pitches appearing around your balls, so expect my heels to pierce your skin very slowly, "step by step", with all my weight.
