That's exactly what the pictures you just posted are: fat all over. That's what they are. Asses with a lot of fat in them. Big. Fat. Asses.I know but I'm saying I like girls with bubble butts. Not fat all over
Why are they so big? Bone? No. Muscle? That's not what muscle looks like.
They are big because they are filled with a substance that in English is called "fat."
