I've had nipple rings since 1997, and love my switch partner to really go to town on them when she's in control. However sometimes she needs one hand for other areas, so we ordered these nipple clamps to allow one hand to tug at the nipples instead of two. I will admit it took a few minutes to bend the clamps out a little to get them to hold on between my chest and the nipple rings - however that was time well invested in my pursuit of increased masochism. I will recommend these to anyone who needs some pressure on their nipples, or just as a pretty decorative addition for anyone to add some hotness to their look.
