I refined my rough calculations a bit. I started, using a partial sphere calculator, by trying to find approximate dimensions that would give me a volume of 10,000 and came up with a diameter of 10½" and a projection of 9½", probably not unrealistic looking at the old photo. Then, adding 2" for a projection of 11½" and 3" increased diameter to 13½" to an approximate of the breast size today, which, given the pictures, is very reasonable, and perhaps even a bit conservative when you consider her boobs project to mid-forearm and her sideboob extends about 6" wider than her torso.
If we can agree to the above, that would mean that Beshine is already at 20,000 cc. But just to show how small increases reflect in the volume, if you add just ½" to projection & width, she would be 22,900 cc, and a 12" projection and 14" width is not a really unreasonable estimate; just look at the current pictures.
We have debated if she could handle such weight and my rationale is that she has has years to adapt and obviously increased in muscle, especially in the legs. To those that doubt she can carry 90 pounds, I can point to numerous girls that carry 400 extra pounds and more; as the weight increases, Beshine has gotten stronger to handle the weight and adapted a posture to accommodate, making it easier. Yet, as videos and her own admission indicate, she is getting increasingly limited in physical endurance, clearly a sign she is carrying a heavy boobie load.
