You're lacking the presence of big, full breasts in your life... Your girlfriend's tits have you so uninterested lately and you aren't sure why... Let me show you how real tits are supposed to be as I try to wear your girlfriend's bra sizes. I start in my own size DDD, and try everything else from there: DD, D, C, B, A. See how superior my tits are compared to your girlfriend's pathetic, tiny ones. By the end of this, you will worship my breasts and show respect for the difference in size between me and your girl.
