In BDSM terms, a zipper is a string of clothespins or other clips, held together loosely by a cord or light chain. [1]
The skin is clipped in the clips for a short time, then the cord is pulled, causing the clips to be pulled off the skin one by one in rapid sequence causing a unique sensation. [2] [3] Zippers come in many sizes and with varied numbers of clips. They are a very popular home-made BDSM toy.
Remember that bit about sensations piling up on one another? The zipper causes a 10-car pileup of sensation and can easily reduce a bottom to screams of agony, followed by a blissful bath of endorphins.
What we like about zippers is the contrast between the flash of excruciating pain as they come off […] and the intense endorphin rush afterwards
