A girl I had lusted after since high school was finally available at the same time I was and it didn't take long to get busy.
At least one time, like bbdubluv45 observed with his Val, I was eating her pussy and looked up to see her twisting and caressing her nipples (she also had a great set of 'bigguns' with large nipples). I am pretty sure she gave them a few licks (but I was drunk a lot back then so maybe it's just wishful memory). Anyway, whatever she was doing got me fired up and I licked her clit and pussy with greater intensity, which we both enjoyed. Didn't really get her to do much with her tits after that and the whole thing fizzled fairly fast.
Fast forward to an ex-wife. She turned out to be way into her nipples and licked at them every chance (I shared a bit about it on this thread here:

So, to answer rzgreen's question: This one certainly did; in fact she reached a point where she could hardly come without giving her nipples some oral attention.
My current wife kinda got into it with my encouragement but she hasn't bothered to keep herself very limber so she can't reach her nipples with her tongue any more. But I know she was doing it on her own for a while- she'd tell me, and send me a few photos periodically.
