here are some shoot of her boobs, first is from 1 week ago, second is from 2 month ago, then the last one is from about 3 years ago.
I don't see a huge difference between these shoots, natural growth can easily explain the slight increase.
and for her ass, I'm 100% sure she kept her natural one as she doesn't show it so often on the social media (so she is not proud / obsessed with it)
