You sure that is mere large_breasts and not huge_breasts?
"If a single breast is of roughly similar volume in comparison to its owner's head..." I think the key Word here is volume. They look and feel "just" large like that when you take in account that natural-like Little sagging there. But Im worried that this body doesnt look plump at all, her stomatch's completely flat, curvy maybe, I got called out by a mod for something similar and I feel it was unfair.
