The book would have smiled had it a mouth.
Serafina was the perfect tool: vain, haughty, arrogant, gluttonous, lazy vengeful and charismatic the book would change the world with her. It just had to get her negative influence strong enough and in the right place. It altered a page as the already bored girl leafed through them, offering up a simple way for her to cast magic spells up to level two.
"A gluttony aura," Seraphina read, "by writing these runes on your belly but once in chocolate and then eating them, from now on you will project an aura of hunger to all women in a hundred feet. Any who cross into this aura will be forever changed. After, you will be able to cast magical spells up to the second level." Interesting, but where will I get chocolate..."
The plump party girl looked about and noticed a single candy bar wrapped in foil on a book shelf, soleSurvivor of the junk food Purge her mother had conducted after seeing her daughter's beer gut. Smiling, the chunky mage ate half of it, melted the rest over a candle, stripped and carefully wrote out the runes on her belly.
Magic flickered outwards as Serafina said the magic words. Across the hall, the skinny chamber maid Amilia felt peckish despite having just had dinner and upstairs her mother, lady marigold was struck with an appetite the hulking body guard and muscular stable boy sharing her bed couldn't fulfill. In her study, Seraphina licked the chocolate of her belly and patted the plump bulge that gurgled happily to have something beyond salad after a tortured day of dieting.
Seraphina pushed her new abilities over the break, mastering cantrips and first catching up to and then surpassing where she should be. She could levitate small objects, put a magical shield over herself, shoot magical missiles and mend damaged objects with a word. In the castles main hall her mother looked over the demonstrated spells with mild approval, then cleared her throat.
"Very good dear daughter, I see with sufficient motivation you can learn," the regal, dark haired woman said, "but, I note that you are little changed otherwise."
Using a mage hand spell, Marigold poked the blondes beer belly, telkinetic finger driving deep.
"You look to have not lost a pound" the famous mage observed, "if anything you look plumper than when you arrived here. How did you fit into this dress?"
Serafina was in her favorite sea green dress, a low cut, backless ensemble that hadn't fit since October. Now it fit her 180 lb body like a glove, although it emphasized her considerable beer belly more than she'd expected. Sitting on her butt reading all day hadn't burned many calories and Learning cantrips to turn water into beer and bread into chocolate had insured her weight gain continued unabated.
"I altered my dresses with magic," the chubby blonde explained.
"While I am glad you are able to, your appearance is not up to standards," Marigold observed, tossing a chocolate into her own mouth, "what will people think when they see you? How will you get a spouse?"
Serafina didn't mention how her mother snacked all the time now. Or how her tight white dress was pressing tight against a little starter belly marring her mom's perfect waist. No, let her stew.
"That's the problem mother," Serafina lied, "when slender, I was distracted. By boys, girls, beer, parties. I was too pretty, now that I am plump I can focus on my studies and only date someone interested in something besides a perfect ass."
"Those words have some merit I admit, the world can easily corrupt us," the vain Marigold who'd spent all morning with a knight, a rogue and a barbarian in her, admitted, "very well daughter, you may return to school."
Serafina grinned, showing dimples and clapped, jiggles rippling across her heavy breasts. Her mother stood up and gave her a kiss, bellies briefly bouncing and demanded lunch. Serafina glutted herself until the seams of her resized dress complained and she had to let it out again. But she wasn't so caught up as to not notice the maids thighs stretching out their tights, the food stains on their lips and how the platters they brought were a little light. Or how her mother ate and drank, ate and drank until her belly sat in her lap and she had to summon shadow hands to rub it.
Serafina left her mother's Castle via a stately carriage, enchanted to be the size of a small house inside. The blonde looked herself over in a mirror, naked. She took in the round bulge of her tummy, the heavy jiggle of her breasts, the plump thrust of her butt. The cellulite and stretch marks, the sagging and sweat...
