I know I will be in the minority on this but I really hope that she does not go too much bigger, 3300 maybe 3500 but stop at that point.
I know plenty here will call it blasphemy but there really is such a thing as "too big"
Most of the models from the 90's stopped at 3000 mostly becasue that was as big of an implant as you could get and no one was using tissue expanders to go bigger than that because either they just did not get that big and/or no one had thought to try and/or no PS was willing to do it.
There were plenty of models from the 90's that fit easily in the "I can imagine waking up to them every morning" standard. A few examples would be Lisa Lipps, Tiffany Towers, Colt 45 and Niki Knockers and about the top end but certainly "pushing the envelope" of that would have been Busty Dusty, Minka and Kayla kleavage, maybe even Chelsea Charms when she first got the string, before she blwe up into what she became.
IMO at or around 3000 making for an H to at most HHH cup size you reach a point of diminishing returns and getting bigger does not equal getting more attractive/sexy in the way going from 800 to 1500 or 1500 to 2500 to 3000 did.
As I said, Minka or Kayla Kleavage were still in the hot/attractive/sexy category but add another 1000 or so and they would have crossed the rubicon from GF material into "curiosity" or if you wanted to be more direct/blunt about "side show" or even more blunt "circus freak" that you may want to play with a few times but potential GF/wife material, no not so much.
Beshine was/is clearly "competeing" with Chelsea for biggest but it were not for that would have been better off to have stopped 3000 - 4000 CC's ago. Keisha Evans looked better when she was at about 4000 than she did at 6000. Martina Bigg who it seems is competing with Beshine would have been better to stop 1000 CC's ago.
Mary looks to me to be about where Minka, Busty Dusty or Kayla Kleevage were when they were at there biggest 15 years ago and she should stop soon, she probably will not stop until she is Beshine sized if in fact she can get that big and sure that will draw eyeballs but not draw much else in the long run.
