Just another "cheap" suggestion I haven't seen anywhere, but use, ever so often myself , are the tiny hair clips used on little girls. You know the ones with 3-4 teeth that are like little clamps. The big ones really don't do a whole lot in my opinion, but if you get the tiny ones their little teeth are deadly. You can get all the little "pins" around a good sized nipple or on a clit nicely. best of all, my husband doesn't ask why I keep a few in the shower (detachable shower head, duh) Anyhoo, buy these by the cardful at walmart or a dollar store and go nuts. I do suggest testing out the springs before buying, nothing is worse than getting home and finding out your new toy has "no bite"
