bigger volume than Ivy at the height of her powers?
Thing is Logan if you wanna put BBW’s along with bubble buts you get skewed takes on things.
If you remember EvaRose BBW (Google to see her vids) her ass is probs one of the biggest out there but purely down to obesity. From a shape, hip to waist ratio, size, lack of stomach Harley Darko and Ivy would probably be clear of most girls off the top of my head.
If you’re after that level then summer is not it but if you want an Amazonian type of built woman then she’s a good shout just not a bubble but more mass.
