There is one thing that horrifies women and it is getting fat. Obviously becoming a giantess can cause you such troubles. You can’t fit in small places anymore because you are too big. You can’t pass through small holes and you start to get the impression that you are fat. Don’t worry, this is not true! You are just a giantess!
