Oh those look like fun! I recently posted a set wearing some nipple jewelry beads except that the things that attach to the nipples are these rubbery plastic loops that tighten around them. Luckily I have pretty good sized nips!

I loved the stimulation, of course. I might have to try the ones like you have soon
