Taylor had become a mom. She gave birth to cubs and was now realizing all the downsides to that momentous life event. One of which was baby weight. She did her best to try and work it off over the following months through exercise, walking and eating right, but her old jeans refused to fit properly. With the new freedom she had found after the war to go out shopping for new clothes, she was stunned to find out that the old sizes she was used to wearing wouldn't fit her anymore. She tried the next size up - still struggling. Her thighs and ass had grown due to her carrying her cubs to term and she was distraught to realize she was several sizes higher than she wished to be. Just one unfortunate side effect of being a mother - the realization that you'll need a slightly new and/or adjusted wardrobe and that your body will never be the same as it once was.
