Matsumoto pulled the pill out of her 'secret hiding spot' and thought, 'Why not take it now?' And, without another thought, she popped the pill into her mouth and swallowed it. Matsumoto closed her eyes and smiled, ready for the weight gain to commence, but nothing happened.
Even after five minutes passed, Matsumoto was still as skinny as before. Matsumoto let out a sigh and thought, 'I can't believe that didn't work! I'm gonna teach that damn Mayuri a-'
Suddenly, Matsumoto felt a strange rumbling in her stomach. She clutched her flat belly in pain and moaned, "Oh god...w-what's happening to me? A-Ahh..." Slowly, her flat stomach began to push outwards as it filled up with more and more fat.
Matsumoto looked down and saw a huge belly beginning to peek out from under her robes. As it continued to grow, Matsumoto placed her hands on her ass and realized her butt had become alot bigger and much softer. Each of her ass cheeks had become bloated flabby balls of pure fat.
Matsumoto's belly continued to grow and grow until it hung 15 inches over her waist. Matsumoto felt her bloated gut and realized it was as soft as a pillow. Her cheeks puffed out until they were swollen and red and her neck was hidden behind three new fat chins.
The busty girl's hips had fattened up as well and ripped through the confines of her clothes, revealing her new flabby thunder thighs for all to see. Matsumoto was happy with what she saw, but her body kept growing.
Matsumoto began to have trouble standing as her belly continued to swell and grow until it was 30 inches over her waist. Her huge fat bloated ball of a belly was so softy and flabby, but the strength Matsumoto needed to even keep herself from falling over was way more than she ever needed for her breasts.
Her butt and thighs continued to swell, too. Her huge thunder thighs became huge pillars of fatty flabs, completely hiding her tiny feet underneath. Her butt had riped out of her robes and her panties as well and they were so big and bloated that they were the only thing pushing Matsumoto off the ground.
Still, she got bigger and bigger. Now her entire body was growing, even her lips and arms. More and more fat formed in Matsumoto's body as she passed 1000 pounds. Her belly kept pushing out and out, growing bigger and rounder with every passing second.
At this point, Matsumoto wished she had never eaten tthe pill in the first place, but her lips were too swollen with fat for her to say anything. Her bloated ass kept growing and growing, an occasional fart coming out every now and then.
Her breasts, which didn't seem to have grown at all for some reason, suddenly lurched forward and expanded to twenty times their original size, riping out of Matsumoto's clothes and bra. They were so huge and jiggly that her breasts just sagged over the sides of her fat growing belly.
As more and more fat engulfed her, Matsumoto realized she could use her powers to stop the expansion. And she did.
Now that the expansion finally stopped, Matsumoto was left with a huge, fat bloated 2-ton body. 'I gotta do something, but what?' Matsumoto told herself as she (somehow) pushed herself off the ground and waddled off...
