Lizzie peeled off her ripped yoga pants and assessed the damage. Staring at her thick, chunky thighs in the mirror brought back memories of before she was a cheerleader, when she had been a bit on the chubbier side. Even then, she thought bitterly, poking the squishy flab, her ass had never been this big and soft. What the hell was going on? First Samantha got fat, and now her? Were they putting something in the cafeteria food?
However, like Samantha before her, her top priority wasn't figuring out the cause of her gain, but rather hiding it, and she began raiding her closet for anything that would cover up her embarrassing flab. Fortunately, she hadn't gained too much in the belly department and most of her tops still fit. Bottoms, however, were another story. Her skinny jeans were out of the question, as she could barely get them past her ankles. She had a couple cute skirts, but realized even her calves were looking chubby and would instantly tip people off to her gain. Eventually, like Samantha, she settled on some cute, trendy sweatpants that were fortunately baggy enough to give her thunder thighs a little breathing room.
With her outfit settled, Lizzie drifted off to an uneasy sleep.

The next day, Lizzie did her best to get dressed as normal, putting on her makeup, a cute top and, reluctantly, one of the pairs of sweatpants. Checking herself in the mirror, she did several twirls to make sure her ass wasn't visible and, satisfied, took a deep breath and headed off to school.
Hanna saw Lizzie in her sweatpants and immediately knew her changes had worked. However, while a few students gave the sweatpants a second look, most ignored them and treated Lizzie like the popular girl she was.
"Time to change that," Hanna grinned. She pulled a small bit of stuffing and began rubbing it into the Lizzie doll.
"So what? Do you think she weighs 300 pounds?" Jessica asked Lizzie as they hung out in the halls.
"Yeah, at least..." Lizzie answered, though somewhat self-consciously as she realized she must be approaching 200 herself at this point.
"What a cow, can you believe she let herself go like that?"
"I know, I mean..." Lizzie paused, as she felt her underwear riding up slightly. She went to subtly adjust them, but gasped when she reached back and felt her ass was even bigger and softer than it had been that morning. "I mean..." she continued, blushing.
Hanna couldn't help herself, and added another ball to the doll.
"I mean, what kind of girl gives up being cheer captain to be a fat nerd?" Jessica continued, oblivious to Lizzie's discomfort.
Meanwhile Lizzie felt in horror as her ass continued to expand, pressing against the sides of the formerly roomy sweatpants. What the hell was happening to her? She realized she needed to get out of here, before her sweatpants burst like her yoga pants did.
"Hey um I gotta go... to class..." Lizzie lied, turning around and practically running down the hall, feeling her enormous ass bounce and jiggle with each step.
Even Jessica noticed, as her globular cheeks were pressing against the fabric of her sweatpants.
"Could she really be getting fat too?" Jessica wondered.
