nipples
 

No pics, but years ago the first time playing with a friend and she about to remove her top and bra, she went to great lengths to "caution" me that her nipples were unique. She exposed them. Wile I was not turned off they were unusual. The nipples were kinda hard (maybe she was excited) but the areolas were kinda large and real dark. She was a petite very white woman.
We fucked and sucked many times after that.
