Bingo fredweena! Mine are pierced and I love it. Lick them, bite them, pull on my nipple rings it drives me wild. Sure there are other places that you can concentrate on but hey, EVERY guy likes those areas.
I found a few years ago that some gentle bites in the nipple-chest area was exciting, then I got them pierced and OMG, what a thrill.
Just wish I had some one to bite them now.
