This has to be the most painful nipple clamp I have ever tried!!!
Then there are two small iron buckets connected...

The rule of the game is to first put three weights on each side of the nipple. If you win the guessing game, you can take one away, and if you lose, you have to put one more weight.
This continues until all the weights are removed before the extremely painful breast clamp can be released...

At the end of the video, you can see that my nipples were pinched with obvious bite marks... I almost cried...
