My belly button needs a little punishing today. I grab a pair of nipple clamps and decide to put them to good use. One end is attached to the top of my sensitive navel, the other one is attached to my nipple. I give them a tug and feel the mixed pain and pleasure. So good, but I want more pleasure. I get my little vibrating egg and use it inside my delicate belly button. It feels so good that I can't help but orgasm after playing with it a few minutes.
