If a woman has a third nipple, let's say a little under her left breast, and goes to the beach in a bikini, and the bikini doesnt cover her third nipple, is it indecent exposure? I can see it both ways. On one hand, the nipple is not on her breast, so there is nothing indecent about it. On the other, the nipple is the essence of the breast. You can show as much of your breasts as you want, but you can't show the nipples. So... what do you think? (This was a pretty stupid idea for a thread, I realize now. Oh well.)
I once knew an Italian girl that had something like a third nipple...not a full one, but a small third one. That was weird! Anyway...regarding your question...I think you delivered some new signature material... "the nipple is the essence of the breast" Excellent! And to answer your question, on the beach, who cares, in Europe it is NORMAL that girls go topless. What's the big deal, two or three...
Male lobsters have two. Don't ask me which one they use, or if both are required, or if they just try to find two lady lobsters at the same time...
