This or any fight style is not reserved for just moms, or any other category of women, many women breastfight the how is a bit more singled out as there ways to breastfight other than just drag and smear together but that is a different question, as for reason, well other than the personal, jealous, confident, obvious reasons you can believe that every woman takes a level of self pride in her bust, lets face it for women they are nuturing scource of food for a womans baby, as well as the allure we get from men and our own as i said pride in our appearence, we may get annoyed that men stare at them as we talk to men but if we really were "offended " we could buy normal tops that weren't cut to our cleavage .
I can also promise you the level of competition between two women in a breastfight is an emotional roller coaster and can be a confidence and pride breaker, i have had women oppoenets openly cry after a breastfight especially if their husband,bf.gf are there to ee it, add in the stakes of taking and wearing her bra as you pose in it or whatever other stakes are agreed on trust me when I say the losing woman in a breastfight will be so angry and hurt emotionally its not hard for a fight to start as tempers are very heated, and more importanlty ITS NOT JUST FOR MOMS
