Many years ago I was at a Works Christmas party with my new girlfriend. The drinks were flowing and eventually we got talking to one of the young (20-21 year old) admin work colleagues who was blonde and reasonably attractive but I just didn't get on with at all. My girlfriend (before she became my now wife) had been out with us a few times and liked her however.
The discussion between the 3 of us somehow got round to her nipple piercing and my girlfriend and I agreed that we didn't like the sound of that, but then again we'd never seen one.
She looked at my girlfriend and said,"I can show you both if you don't mind him seeing?"
To my glee my girlfriend said,"No problem" as the admin girl casually lowered the shoulder strap of her little black dress and flipped her left tit out. She then gave the pierced nipple a little poke before putting it away.
The tit was lovely but the pierced nipple didn't do anything for me.
Here's a few pictures of her with my now wife at that party.
