The little piercing with the little bell on the end of the pretty little chain is very cute. Cuter? Making the bell ring as she writhes under your whip:
P.S. If you want to play this game with your girl and she doesn’t have one of those piercings, two alternatives come to mind:
1) Get her a gift card for your local piercing palace; or
2) You can buy her a clamp with a bell on it that will work — dare I say it? — in a pinch.
