Chapter 1

It was called The Fattening, and it almost bought down civilized society. March 22nd, 2025, was a disastrous day for the human race. All across the globe, adult women got FAT. Not just chubby or even chunky, but morbidly obese. Some women, it hit them all at once. Some, it took a few days of gradual but fast weight gain. But in the end, anyone past the age of 20 and with XX chromosomes mostly gained so much weight, their lives were forever altered. Many gained weight in their own homes, on a comfy bed or couch. Furniture was broken, beds destroyed, lovers probably crushed under fat, but they were lucky.

It being a Saturday, many were home with families. Some, sadly, were at work. When every svelte 110 pound flight attendant on a plane suddenly gains hundreds of pounds, that can cause problems. Even worse if the pilot is a woman. Many planes went down when their female pilots filled the cockpit, pushing the controls into a freefall. The same was said for any important job or career where a suddenly large size could severely inhibit work. Many doctors and surgeons missed calls, too fat to get up and hands too chubby now to delicately work on a human. Healthcare ground to a screeching halt, as the nurse and CNA population exploded (literally.) Hospitals scoured the streets for male nurses, and any female ones who still had some mobility left.

The amount of weight gained varied, but it seemed to always be at least 300 pounds and the max was, well.....as fat as a woman could be. The average was 400, and seeing as the average weight of a woman in the US was 170, this put them all well into morbidly obese territory once they were done expanding. Height was no factor in how much weight was gained, so almost any shorter women were crippled with fat immediately.

As I said, there was no "limit" per se, the only limiting factor being how much pure fat the human body can take. While the average gain was around 400 pounds, many women gained more than that. It was not uncommon to see gains of 500, 600, even 700 show up. A few very unfortunate ones gained even more. Whatever fat cell mutation/evolution m caused this, it did not account for the health of the individual.
Some aspects seemed to be enhanced, like the elasticity of human skin, but the mutation could only do so much. Angry red stretch marks hit every woman hard, but there were no reported cases of anyone "popping" thankfully. Just very tight, very fragile skin that needed to be cared for in the aftermath.
However, normal health complications arising from obesity all reared their ugly heads overnight. The amount of heart attacks and coronary failure was astronomical, and diabetes now affected half the population. Anything obesity related, and it became a world wide, immediate issue.

If you were a fat gal before this started, then odds were not good for you. Fat soccer moms and wide hipped teachers, girls who "had a sweet tooth," all regular women who just got fat over their lives, completely buried under fat. The entire population of plus sized influencers, OnlyFans models, BBWs and SSBBWs, and many more were stricken with lard. Think about it, if the average gain was 400 pounds, then there wouldn't be an "original" fatty left to stand on her own feet. IF she made it past the initial fattening.

I won't cut corners here, many just didn't survive. The 450 pound fat activist that loved talking about body positivity didn't seem too happy about it at 900 pounds and unable to breathe. The 500 pound death feedee had a heart stopping orgasm once she crossed half a ton and her vision started to get splotty with her arms going numb. The 300 pound fake feedee and gainer who scammed people for years got her just desserts when she suddenly couldn't see with all the forehead fat blocking her vision.

It wasn't a pretty day, and the next few years were not easy. Global conflict and despair ground to a slow halt, as governments and infrastructure were severely compromised. If humanity didn't come together and figure this out, the world would be set back decades, if not centuries. But, perhaps it would help usher in a safer, better age?
