Let's have a thread where we post stories that feature weight gain and fat stuff mixed with petplay and animal play. This will be for standard "normal" petplay, but also fat-specific forms like pigplay, cowplay, and others.
Actual transformation into animals is, I guess, fine, but it's not the real purpose of this thread; I'd rather like people to post stories where someone is fattened up and in the process treated like a pet or an animal, without transformation necessarily being required. Dom/sub elements are practically a given, as well.
