Well, if you really must know, I found a sort of resemblance in the face with the huge portfolio of pictures you've been posting of yourself, over and over and over... So, I posted it to compare with you.
Notice that although the girl in the pics tits are a little smaller, they don't hang down around an ample waistline like yours do. And while hers do not remind me of a bum, neither do yours. I'll not bother to do further comparisons of your bodies as that would necessitate the need to bring in pictures of the back end of a knock-knee Llama.
But, if I were to compare your tits with a bum, it would have to be the bum of some strange looking beast in which the cheeks droop down and are separated with a space. Quite frankly, I can't even imagine a bum looking like that, except maybe on a 95 year old woman.
Hope that helps.
