Please welcome this new model to MetalBondage.com: she is called Curvy Ra and she looks amazing in a custom metal corset and steel posture collar!! She is ‘not great’ with nipple clamps, she told us. No worries, we have the perfect machine for that: the Nipple Clamps Training Machine! Obviously, Curvy Ra wasn’t going to like this procedure, so we had to restrain her to a cross and ballgag her. Once she got going, it went pretty well. Sure, it hurts a lot, but she really needs the training!!
