A large, obese, tan furred, black haired, bottom heavy, pear shaped cat sits down on a bench in town, relaxing. She sees a large, obese, blue haired, tan furred fox walking. “Hi” She greets the fat fox.
Imagine your favorite character finding out that they’re pregnant, but they don’t want their friends to find out until there’s absolutely no way to hide it. So, even though reluctant at first, decide to put on a little weight to help keep the baby bump hidden for a little while at least. But, as they get further along, they find that they actually like being a bit more plush than usual, and decide to keep it up for just a little while longer, since they feel that they’re still not ready to tell their friends just yet. How long they keep this facade up is up to the reader/writer, as is how they’re friends react once they finally find out.
