Attach these adorable Bound to Please Nipple Clamp Bells and you'll hear your lover quiver and tremble with pleasure. Small metal bells on the end of each clamp will ring out every time there's movement. Attach the tweezer-style clamps to the nipple and use the sliding ring to adjust the pressure. The further up you go, the tighter they become. Rubber tips offer some comfort to the wearer, but this pair of clamps certainly offer an intense pinch that fetish fans will love.
