Nipple Stretchers with Japanese Clover Clamps

If only a nipple clamp is not enough! These nipple stretchers are a challenge for every straight-laced submissive. These nipple stretchers are based on a set of clover clamps. These are clamps which have the property that they squeeze harder as you pull harder. And that is exactly what you do by tightening the screw... In short, a very mean toy, and it looks frightening too.
