I bought this rubber strap, when Tiki started falling behind on her classes to get her massage therapy license. All these years later, 'The Devil's Tongue' has struck fear into the hearts (and butts) of many a spankee. I don't use it on many models, but with Hailey I have included it many times. This long spanking, with this extremely painful strap had Hailey looking scared every time I brought it out. If she had messed up and I found out, I made sure that the look of fear was just the start!
