The heightened sensation brought on by clamps tightened on my nipples gets me hot, but I hate the way tweezer-shaped clamps tend to slide off at the seemingly slightest tug. What's the point in compressing that delicate flesh if you can't yank on it too? If you've long wondered the same thing, then I highly recommend Spartacus' square nipple Adjustable clamps. These things stay on much more securely than other styles I've tried, which is a huge plus!

The superior design doesn't end there, though. Adjustable clamps are sturdy and secure all the way through. Made of a nice heavy metal that feels solid and cool to the touch, these clamps distribute pressure evenly across the surface of the nipple. Plus, the square design allows the clamp to go further back on the nipple, right up against the areola, providing a sensation that I found much more pleasurable than the typical superficial options. I'd imagine their design would work for a wide array of nipple sizes.

From an aesthetic perspective, this bondage sex toy is incredibly sexy. They manage to look utilitarian and intimidating while also appearing artfully kinky. They display the clamped nipple really well, with a good thick chain linking the clamps together. I found that the best way to position the clamp is to have the bar running horizontally across the nipple, so that the screw points vertically down from the nipple. (You'll understand better once you have a pair of your own to examine.)

So far my favorite way to enjoy Adjustable clamps is in conjunction with a rope chest harness. (You can find directions for how to rig one in Midori's The Seductive Art of Japanese Bondage, as well as in Chanta Rose's Bondage for Sex.) With the whole chest bound, constrained, and displayed like that, these square clamps are a perfectly wicked finishing touch.
