Rayne and Tracy have been friends most of their lives. Each is a bit envious of each other. Rayne hates it that Tracy can eat and never stop and look really great. The fact is Tracy is about 30 pounds overweight to her species. Tracy breast job she got when she was 16 is part of the fact that she stays there *otherwise she would have the same size chest, but a more visible ribcage and no hips to balance out. The other part is that she is lazy.

Tracy is still annoyed even with a boob job and everything she still cant match Rayne's chest size.
