Young Brunette Girl Reveals Her Big Natural Breasts At Home

The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infants. Both men and women develop breasts from the same embryological tissues. However, at puberty, female sex hormones, mainly estrogen, promote breast development which does not occur in men. As a result, women's breasts become far more prominent than those of men.
