If Jon had checked his app more thoroughly before losing it he would have seen that the way the wish had altered things in a way different from Tuesday or Wednesday. Tuesday had seen girls swap to different families, based on those that were younger and could be identified as a girl in an age sense. Wednesday had seen swaps based on the gender identity associated with being a girl, causing any female on school grounds at the time to change.
As Jon had only begun to realize Thursday was something different entirely. He was unaware of the specifics, but had slowly found family dynamics shifting in different ways. The number of girls swapping ages had been high over the previous two days. Jon had only learned that day while studying the app that the people swapped into new lives could have an effect on the course that life would take. It wasn't an exact one to one. There were smaller changes like how Kyla Leeson had become a teacher of a different subject than the original Miss Robertson. There were bigger cases with more consequences such as Lucia Diez not following the path of the life she'd taken over on Wednesday as a single mom, but marrying history teacher Mr. Penner.
As more women at a wider range of ages were swapped more decisions in the past were being altered based on their personalities. A broad range of factors were altering, including how and when people met, how they decided on careers and what chances they'd take with them, if they would be in a different location at a different time, and how many children families were having among other factors.
Jon had no way to know at the moment he had experienced the change in his family history due to this. The reason Stephanie had bee born to a Vietnamese woman was that in the altered past his grandfather had a conversation with the now elderly Rachel Wachowski. This had led to his grandfather enlisting in the army, being deployed to Vietnam, and ultimately falling in love with a woman there before bringing her and their new daughter home to the states.
The stone rearranged many families, causing some with many kids to have fewer, or even none. Others were now in need of more space as their family sizes increased. It was not limited to the children of Jon's generation, as a sift had occurred in the population of older women as well.
In one part of town Zoe was still the mother of the Brewer family. Carly had told her she'd be staying late, and Zoe had escaped the swap due to deciding to stay home and continue eating. When 3:47PM hit she hadn't swapped families, but she did experience changes of her own.
"Eat up everyone, there is plenty to go around. I don't want anyone saying they didn't have enough." Zoe told everyone seated at the table. A veritable feast had been placed before them on a banquet table, but it was a common necessity.
In her altered past Zoe Brewer wasn't a mother to one like the day before. She was instead mother of four well fed girls that took after their mother. Each of her children was well onto a life exemplified by their mother, morbidly obese and enjoying every moment of it. Her eldest daughter, home visiting from the community college in town, was the largest at around 350 pounds. They all took after Zoe, with massive multi layered guts that hung over their thick thighs when they stood. Each had been blessed with huge udders as bug or bigger than their heads that sagged from their excessive weight. Their asses were colossal shelves that wobbled and shook with every step they took.
Zoe, who as a Brewer had been instilled with a desire to become so fat she'd be immobile was closer to her goal. The extra pregnancies had increased her time laying around being waited o hand and foot by her husband. Where she had been 450 pounds the day before she was now topping the scales at nearly 600. If Jon could see her he'd be amazed at the enormous woman his little sister had become.
"I don't think you have to worry about that Zoe. Your girls got our healthy appetites, so they'll have no trouble eating." A woman around Zoe's current age said from her left.
"I've taught them well sis, but we can only afford so much food each day. It takes a lot of money to keep all this fed." Zoe laughed as she gave her belly a smack, causing the ocean of fat to jiggle.
"You've got that right." Her new sister laughed, her own massive body quaking and wobbling. She had her own daughter there, having a large family meal with her big sister and nieces. She had no idea before that afternoon she was much younger, lighter, and had yet to even have sex. That did not matter to the obese woman who yearned to overtake Zoe as fattest in the family.
"When we're done you girls need to study. You need to get those grades up." Zoe told her girls.
"But mom, studying is so boring." One of the girls pouted, her double chin sagging down.
"What can I do to get you girls to get your grades up? I already bribe you with enough snack privileges." Zoe shook her head.
"Well, there is this handsome tutor who is really smart." Another girl spoke up.
"And you want me to pay him to help you girls?" Zoe looked over the three still in high school. They had all been different ages and lived different lives around town. It was a mix of younger and older to add them to the family, but it didn't matter to them. All they knew was they were one family and always had been. "What's his name?"
"Jon Nguyen" The girl eagerly replied.
