Sarah and Annabelle are big tit sorority girls going their initiation process. In order to make it into their sorority you must have a D cup or above. They make their potential new pledges send in their bras so they can see if they measure up. This year the bras are extremely small and pathetic. All the girls that sent in a bra are flat-chested with bras ranging from A-C cups. Obviously this won't do for their big titty sorority, so they skip out on accepting new members and just try on the small bras and humiliate the flat-chested girls instead.
