The Nipple Clamps Training Machine was a terrible ordeal for young Diamondly a while back. I decided to bring it back for our awesome reluctant volunteer Cindy Dollar. The problem? She has very sensitive nipples. So I had to make sure she was really secured very well, with no movement in her neck, arms, and legs. Cindy was completely stuck and unable to move, her labia clamped (she didn’t like that either). The machine certainly did its job! Training her sensitive nipples, hurting with every stroke. Cindy made a sound through her harness gag every single time, at the rhythm of the machine. Very beautiful to watch. So relentless and mean, it is one of the most evil machines I have designed so far!
