Here are the biggest nipples I've encountered in real life, easily. They belong to a thick Filipina and are just shy of 3/4" long, and if anything are even thicker than they are long! Bigger than small size gumdrops, it was amazing to feel them in may mouth. They may look impressive in these pics, the pics still don't do them justice. The pic with the guy's hand (that would be my hand
) I scaled to actual size.
