Rarity's snout scrunched up at the scale as the number spun around. She'd gotten used to exactly how long it took for the scale to settle on the weight she knew it would be, because it always is.

But today, it took a little too long. It was only a second or two, but she instantly felt the bottom of her stomach exit her body and enter orbit. She was mortified.

138.

138.

This wasn't 132, and so it was a huge problem.

Thankfully, she had a plan for this. Knowing that there were simply some times she wouldn't be able to avoid a couple of pounds, be it from parties or travel or what-have-you, she was prepared. A unicorn was nothing without magic. As she stepped off the scale with a quiet, annoyed snort, she turned her head towards the organized chaos that was her bookshelf. The spine of an inconspicuous book with no title lit blue as it floated off the shelf and right in front of Rarity, pages spinning as she located one in particular.

Miracle Mare's Miraculous Model Maker emblazoned the top of the page, even going as far as sparkling purple when the page was first opened. It was an interesting effect, but one many spell tomes had already exposed her to. Still, it wasn't the title she cared about, it was the spell itself. There had been a few times before she'd cast it on herself, with expected results, but memorization of spells was difficult for all but... well, Twilight.

Rarity's eyes scanned along the page as the words tumbled through her mind, chin lowering just a touch as her horn began to glow and the magic of the spell began to flow through her whole body. Her flanks and belly took on a dull glow, Rarity targeting the "problem" spots. The page was gripped as she prepared to flip it, fairly accurate timing required for a live casting of a spell like so, and just as she reached the last word of the page...

It was stuck. Half a second passed and she tugged at it again, but something had stuck the pages together. A full second, and far too much time had passed, her concentration lost and her mind let the spell slip. She squeaked in pain as her horn let out a few sparks, vivid pain having struck her in the head. The spell failed spectacularly in a shower of magic, a shiny glow radiating off of her hips and belly as she screwed her eyes shut, reflexively taking a step back from the tome as it slammed down against the floor, shutting closed as her magic washed away from her.

"Ow," she said, wincing slightly as her forehead throbbed. An angry groan rose up from her throat, before being diffused into an annoyed snort instead. "Whatever," Rarity said as she trotted away, striking the tome on the ground with a hoof as she passed it. "I'll deal with it tomorrow."

) ( ) ( ) ( ) (

Rarity fluttered her eyes open as her alarm clock rang, though the sleepmask she wore kept her blind. Still, her hoof shot out of her sheets and slammed against the top of the clock, one last ring! punctuating it before it stopped. The movement caused her chest to wobble slightly, and she had to pause and think about that for a moment. Why was she wobbling?

Her horn ignited as she flung her sleep mask off, head tilting down to glance at the rest of her body, the second chin she now sported bunching up and brushing against the bottom of her snout. She swallowed, hard, eyeing the mound that now rose above her while she lie in bed, rounding out her sheets where her soft, lithe barrel was when she went to sleep.

An ear-shattering screech rung out, the sleeping Opalescence bolting out of the room reflexively at the sudden noise. The sheet that covered Rarity's body was gripped in a blue, magic glow as it was flung across the room, plopping against the floor after it hit the far wall.

Rarity's expression soured immediately, though the shock kept her mouth agape. She was, in a word, huge. Her flat belly, though slightly curved, now bowled forward above her, spreading out to the sides against the bed where she lie on her back, bulging down between her legs, obscuring the view of her flanks. A part of her was glad she couldn't see any lower -- it saved her from knowing how huge her ass had gotten.

She shifted in bed as she pushed herself to roll over, but the new-found weight proved to be a bit of a struggle as she fought against her added girth. The sensation of being weighed down so heavily, especially in her incredibly pliant bed, caused her to try several times, grunting as she tried to pull herself up to her hooves. Finally, she gave herself a push with magic, the tubby unicorn shoving herself out of bed and to her hooves where she nearly immediately hit the floor, knees not ready for such added bulk. She kept her footing as she immediately trotted to the wall mirror she had in her room, audibly whining at the feeling of the round belly she now had brushing against her legs as she bounced over towards it.

She stood facing it, biting her lip before she turned to the side, head cocked in order to glance at her body. Sure enough, her worst fears were realized! The lithe, trim figure she went to bed with had disappeared, replaced by a much rounder appearance. Her flanks had widened significantly, distorting the diamonds on her hips just a touch, enough to make them asymmeticrical. Where they each matched each other the night before, the one highest on her leg was now taller and the one closest to her rump now wider. It was infuriating, she realized, and not just because she was, well, fat. Her rump thickened in pace, too, rounding out behind her far further than it ever had before, drooping slightly as it reached her knee and bulging down between the joint. It was quite an ass, though she wouldn't be caught dead admitting it.

Farther up, her eyes reached that belly. Drooping low and wide, she couldn't help but jerk one of her legs slightly to watch it wobble, the huge barrel of fat quivering with the movement as it bounced between her legs. Her flanks indented it, wide enough to match their girth pre-gain, and the faint outline of a roll bulged along the top right where it melded with her huge rump. It swung below her, still quite a distance above the ground (thankfully), but still incredibly obvious - there was no hiding this, like there was the five pound gain from before. She was downright fat, and there wasn't much she could do to cover this up. Her chest, too, had swollen a bit, soft desposits forming around her shoulders and her neck, even while standing, was outlined with a second chin as it rolled down to meet her chest.

She inhaled sharp, before letting out a huge whine.

The only question she had, as she bit her lip again, looking at her pudgy cheeks as they bulged out, was how the hell she was going to get Twilight to reverse it without being seen in public. After all, it had to be reversible.

Right?
