I am looking for providers that have long, hard nipples and the longer, the better.  Any information will be greatly appreciated.

If you are not looking for FS, Melissa has the nicest nipples around.

Check out Tia on my website. She's got great nipples.  I can send more pictures if you'd like

Melissa's nipples  are to die for!  I get a raging hard on just thinking of them!!!
