While I do think they're underselling her bra size, I can't imagine that theory holding water. Of all Christina's sister sites, there are many girls of varying levels of flatchestedness to choose from if one does not like big breasts...I can't imagine why anyone would pay the member fees for her site if they didn't at least have a passing appreciation for her boobs. Come on, no one can deny they're the main attraction. As far as I can tell, each of the -Model girls has some standout feature or something about them that draws a prospective fan in--many of them have awesome butts, for instance. Everyone knows Christina's front porch is the MAJOR thing she has goin for her, and all her videos and pictures emphasize just that. So to undersell her bra size seems kind of ludicrous...I don't think printing the truth about her bra size would turn anyone away.
