First of all, the thing you need to understand is weight loss is inevitable when it comes to the models regardless of how into the fetish they really are, the reality is maintaining a five hundred plus pound body isn't as easy as you think and like professional body builders who retire from competition a major loss in size is going to happen because they aren't pushing themselves to the limit anymore, sure someone like Ash will probably hold out as long as they can before dropping the weight but that has more to do with the fact that for a lot of these women their size is what defines them as people and without it they wouldn't know what to do with themselves rather than some sexual desire to be huge.
