Yestrday me & my girl were fooling around with cream & stuff. I was licking it off her nipples & things were getting quite intense. I was sucking & licking for about 10mins & she came from it! I was so impressed, I've always wanted a girl that can do that. I think it was a first for her, I've never done it to anyone either (not to the point that they came anyway).

I thought it was so hot.
How common is this? Can many girls cum just from nipple stimulation?
