Ok so beside this girl having incredible curves and obviously she doesn't mind showing it off I have her name....Brenda Lynn and well that's about it. So I guess that's it.
Both men and women develop brea*ts from the same embryological tissues. However, at puberty female sex hormones, mainly estrogens, promote bre*st development, which does not happen with men. As a result women's brea*ts become more prominent than men's.
