Well, no shit?!??
There really is no such thing as a "skinny woman" that has tits that big.
Only "large ladies" have "large" mamories.... There of course are the "abnormal" ones out there, but it is not the "norm"...
(Of course I have dated the "not norm" ladies with large breasts, and if they are natural, they sure as shit don't look like their fake counterparts... Jeasus, what is this, 10th grade?)
