Clothespins "Zipper" by Nina
Clothespins are one of the most popular, old-fashioned toy. Usually one or two clothespins works enough to cause a yell, but there are always pain junkies in this world.
I made this tools called "Zipper", dozen of clothespins tied together on a string. Simple yet effective in a way of producing pain.
Clothespins do cause varying amounts of pain that depends upon their placement. The nipples, chest and genital areas are the popular areas. You can extend them in patterns from the crotch up the abdomen, legs and thighs, and on the arms. Lastly you can put some on the mouth, the tongue, and the ears, though they will hurt like hell on these sensitive places.
There is no any really good way to take clamps off painlessly.
Clamps of any kind are going to hurt the most when, and during the minute or two after they come off. Taking them off quickly might be an effective way to get it over with. Doing so slowly one at a time is just more sadistic. Lots of adrenaline rush!
Zipper can be cruel and hurt like hell, so it might be off limits for most of submissives. But once you are ready to go further, I would be happy to guide you. Ultimately I want you to feel the pain rush while you are having orgasm. Nothing can beat this sensation.
