One more lucky sub...
A depiction of the perfect placement of Japanese clover nipple clamps. Now pull like hell (but not hard enough to dislodge the device) and let the clover action clamp down as hard as possible on that nipple!
It always results in a certain enigmatic smile on the sub's face... DAMN!!! (Meanwhile insert evil grin here!)
