Huh?

Is it true that her knockers are not natural?
What would ever give you that idea??? Seriously?

Her breasts hand pretty good, and are otherwise "more detached" (underneath) making even a "lift" difficult as part of her bust.

Also, if anything thinks the size different is even remotely related to having fake breasts, understand a great majority of women are not perfectly symmetric. Hell, even women like Brandy Taylore have a size difference when you study them closely.
