A mates wife Wendy never wears a Bra and has nipple rings, awesome, and will show them to us anytime. Wendy has breast implants to make her a 34dd and says she isn't going to spend all that money and not show them off.
My wife Julie used to go out regularly in the 80's without a bra and being a 36d it was an impressive sight. What made it so special was that her nipples were pierced and she wore lovely gold rings in them, this was in the days before piercing became popular.
