I get certain strong satisfaction -- people not in to BDSM might even call it sick satisfaction -- out of binding my naughy slave in leather & giving her good spanking. When my bottom is for true naughty I place her on stretching device & view her try to squirm. Whipping my helpless slaves round bottom really does turn me on. Whether I am spanking her or whipping her, I like to watch her round bottom turn colors. First it flushes gentle pink. Then it becomes more of magenta, than scarlet, & finally deep crimson. Sometimes I raise welts. I love watching it change color, longer & harder I hit her.
