Ah yes, the nipple clamps. We enjoyed using this product and it does exactly what you think it does: pinch both of your nipples while the chain can be tugged and played with during sex. It can be used on a male or female and the build quality is actually pretty good considering the price. For under $10.00, you really can’t ask for much more. I personally like to have my nipples played with until I orgasm, so putting these on during sex or oral sex mimics the sensation of having your nipples nicely pinched with someones fingers. The tips are a soft plastic and you can loosen or tighten the clamps so they are comfortable and fit your nipples. These can also be used to torture your man if that is something you both enjoy doing. The clamps stay put and as long as you do not tug too hard they seem to stay on well. I’d recommend this product to anyone looking to add a little nipple play to their bedroom.
