Because of her young face, she doesn't look like a mom. However, as she grows older, she would grow some fat in her ass and hips as well as on her boobs and face. At that stage, she would be a very tasty milf.
Well said!!! Usually, I've seen, girls or women with small boobs have heavier bottoms and curvy hips. What they miss on the breast, makes up on the butts.
