"Stepped Over Step-Sister": An Exclusive Cut

Two more of these to go after this. "Fit Friend, Fat Friend" and "Buffet Buddies". It's been a lot of fun writing role reversal stories, but I have to be honest, this has been a beast of a collection.

Enjoy!

---------------------------

Georgine hated her step-sister. It wasn’t just that Delaney was everyone’s favorite, or that she was as vain as she was beautiful. It was just that everything just came so easy to her. Delaney excelled at everything. She got whatever she wanted, especially the love and attention of their parents. Georgine had always known Delaney was a daddy’s girl, but she found her stealing her own mother’s affections away, and that was unbearable.

Delaney was the perfect daughter, the perfect student, the perfect everything. Even when she went to college, something Georgine found herself unable to get into, she chose to stay home instead of dorming. This meant that Georgine couldn’t even escape Delaney’s torments. Her step-sister loved to tease and bully Gergine endlessly over her weight, or her intelligence, or any number of other things.

But it appeared that Delaney had made some quick enemies in college, and one day one of them paid Georgine a quick visit.

They had brought Georgine a small device that could allegedly swap DNA and modify genes in others. Georgine was encouraged to try it on her prim and perfect step-sister, and it would prove to have some very weighty consequences.

It started so simply. Delaney suddenly had a proclivity for sweets that she never had before, a craving that seemed small at first but began to grow. Georgine loved to smirk when she caught Delaney sneaking her snacks, clearly ashamed of her new little quirk, her need for a sugar fix. After that came a general increase to her appetite.

Georgine would watch as Delaney started taking larger portions at meals, and then seconds and even thirds and always desserts.Delaney was becoming a greedy little piglet right before Georgine’s eyes, and the eyes of her judgmental parents. They would chastise Delaney constantly, fret over her change in diet, but Delaney just couldn’t help herself. Deep down inside her DNA she was being reprogrammed in such a way that she needed to be a naughty snack sneaking little piggy. The only thing any amount of chastising did was increase Delaney’s anxiety which in turn unlocked her new capabilities as an emotional eater.

And Georgine, ever the good sister, was always there to provide a shoulder to cry on, and more snacks. She loved to watch Delaney eat her way through a bag of fun sized Snickers like a chain smoker going through a carton of cigarettes. One after another they would go down again until the package was gone. Luckily, Georgine always seemed to have another one ready to go whenever Delaney needed it.

Georgine wasn’t eating much junk food herself. She found, thanks to the swapping of key pieces of her DNA with Delaney’s better genes, that she was able to stick to dieting much easier. And when she traded metabolisms with her step-sister, this meant that she had a lot more energy to exercise and that that exercise was a lot more effective. She found herself steadily dropping weight while her previously slim and sexy step-sister was starting to pack on the pounds.

Delaney put on weight so easily that she sailed past chubby and into full fledged fatness in a blink of an eye. It seemed like just when people were starting to notice she was gaining weight and getting on her case about it, it was already too late to truly stop her from ballooning. Delany had been so slim and trim, but thanks to Georgine’s efforts, she became a blubbery butterball.

Her abs became a big fat blubbery belly. It started out causing a bunch of rapid fire rumors that she was pregnant, but those luckily died down quickly as it soon became too soft, sagy, and jiggly to be mistaken for anything other than a greedy gut full from food and fat and not from pregnancy. Some people still enjoyed playing a joke on Delaney where they pretended to think that she was pregnant as an excuse to squeeze her soft squishy belly and then loudly declare that it was all just blubbery as they shook the fat and watched it still bounce around when they let go, shaking like a bowl of jello just out of the mold.

Delaney’s perfectly pert ass became a blubber butt as well, a pair of plush pillows grew soft and saggy and covered in cellulite. She grew the kind of ass that was constantly getting in the way, knocking stuff over and making others uncomfortable when she went to sit down next to them. She was a wide load with a big spongy broken down dump truck ass. It was a good thing that her fat ass made sitting down so comfortable because she was doing more and more of it on a daily basis.

Delaney’s breasts grew slightly bigger as well, something that was inevitable given her large amount of weight gain, but Georgine made sure to keep the good genes for the better breasts, so Delaney’s while growing softer and saggier were still far outpaced by the rest of her growing body. Instead, Delaney developed doughy bingo wings as her arms grew noticeably fat and flabby and far weaker than they used to be.

Thick tree trunk thighs replaced the trim and toned ones that Delaney used to have. These thunder thighs were tubes of fat covered in cellulite that shook with every labored step. They slapped and rubbed together and forced Delaney into a slow and awkward waddle. That seemed to be a theme for Delaney as her genes kept being rewired and the weight kept piling on. She seemed to be finding everything she did to be slow and awkward.

Her pretty face, with her innocent, angelic features became dull and piggish. She grew a fat face with jiggly jowls and a doughy ever present double chin. The puffiness of her face made her look piggish with beady eyes that had lost their confidence. They looked dim and dull, and they were a perfect fit for Delaney, whose intelligence took a real dip thanks to Georgine’s machinations. 

Just like Georgine had planned, Delaney soon found herself too dumb, as well as too fat and lazy for college. To the anger and humiliation of her parents, Delaney dropped out and found herself stuck at home indefinitely even as she inevitably slipped into a slew of menial jobs that she continually found herself too lazy to keep up with. Finally, she found herself working as a janitor and doubling as a cafeteria lady at the high school that she was once the queen bee of, the perfect punishment in Georgine’s eyes.

Georgine went on to be quite successful. She was confident in her curves and made her way to college where she excelled. Her parents were quite proud of her and showered her with press just as they shunned Delaney.

But still, there was a feeling of bitterness that Georgine was left with. Her parents were only so proud of her now that she was successful. They never truly appreciated her before.

Maybe they could use some rewiring too.
