Cheer up your nipples!
Many people greatly enjoy nipple stimulation, as it's very simple to do, requires very little risk compared to other forms of bdsm, and can greatly enhance sexual pleasure between partners or individually.
Nippless are very easy to use. All you have to do is squeeze, apply to the nipple, and release. To remove, simply squeeze again and pull away.
Each package contains 2 nipple suckers.
