I also happen to see a couple of time my female colleagues and
friends nipples. Also, most of them are flat-chested. 1 thing that
never fail to amaze me is the size of the nipples. somehow, those
with flat chested always have very protruding nipple, usually very
big in proportion to the brea5t size. and they always wear a size
bigger bra or loose bra to show the world their assets.
