How big does a pair of tits have to be before they fall into the big tits category for you? For us they should be at least D cups, although some of the babes with perfect C cups make the list. Because we know that some of you like the super busty babes we also include those ladies whose ta tas are off the charts enormous. Some of the big tits are natural and some have been made that way through the magic of plastic surgery. All big tits are wonderful to us.
