1. Spiked clover clamps. I put them on myself, and I would have to be tied up to wear them more than a few minutes.
2. Suspender pin clips work well for a quick piercing and crushing, and has a handy loop for attaching weights.
3. The lowly alligator clip. Can be quite a torture if squeezed, pulled on, twisted, or weighted.
Since I have no favorite among the three, my playmate would have to choose which one she wants, or she gets all three at once (nipples and clit).
