i think the girls who do cosmid choose cosmid because spreading pussy shots and overall vulgar craziness is not forced. that is why girls like nikky or amanda love never show the pussy. it's mainly focused on the large tits. IMO.
the pussies that you do see are from chubbier,larger models and to be honest those are even tame pussy shots. and those girls mostly do the awful "peek-a-boo" pussy shots where you barely see much.
