Are you looking for hard stimulation of your nipples? Then you should try the Spartacus Japanese metal nipple clamps.
The nipple clamps are beautifully designed and provide a hard, intense pressure on your nipples - a pressure you can increase by pulling on the chain that connects the two clamps. The more you pull on the chain, the more the clamps titillates and squeezes. The metal of the chain titillates the skin, as well as the weight, which adds an extra dimension.
Are you new to nipple arousal and clamps then we suggest that instead of the Japanese clamps you start off with our gentler models where pressure is adjustable.
