Starlight sat in the dim lighting of the runway, well away from the bright stage lights. She sat as far away from the cameras as she could, and was wearing thick glasses and a large hat. Hopefully, nopony here would realize who she was. She wanted to be able to watch her plan play out in real time, and she couldn’t do that if she was discovered.
So, she sat in silence, trying to quell the seething rage swirling around her gut. She may not be able to hurt Princess Twilight Sparkle herself, but her precious friends weren’t so well-protected.
Upbeat music started to play, and the chatter that had filled the room died down as ponies got settled to watch what was the biggest fashion show for up and coming designers in Canterlot. Of course Rarity was one of the designers invited, and she’d even had to model her own dress due to her chosen model calling in sick. Starlight may have played a hoof in ensuring Rarity got a spot in the spotlight, but everything had been very fortuitous in allowing Starlight this kind off opportunity.
So, Starlight waited with baited breath. She gathered magic in her horn, and took a deep breath. If her timing was off, the spell wouldn’t work properly. She’d spent too much time on this for things to go wrong now.
A voice, carried through speakers surrounding the room, spoke, “Hello gentleponies! I’m pleased to welcome you to the Up and Coming Designers Showcase. I know I’m excited for what these mares and stallions have in store today. Put your hooves together for Rarity of Ponyville, and her new spring line!”
There was clapping, and the music started up again. When the curtains at the far end of the runway, Starlight channeled the spell. She knew her hat would cover up the brightness of her horn, and smiled when her turquoise magic magic sunk into Rarity unseen and unnoticed.
A spotlight shone on Rarity, and for several seconds nothing seemed to happen. Rarity looked as perfectly coiffed as always, her mane and tail perfectly styled. Her mane was piled into an elegant updo, though her tail had been left alone. She wore more makeup than when Starlight had seen her last, but that was to be expected. She was showing off after all.
Rarity wore a royal blue garment that was tight around the bodice and upper body, and flowed elegantly off of her flank. It was highlighted with silver trim and embroidery, highlighted further by a moon pattern across her flank. Gemstones glittered in her mane and along her back. It was truly a gorgeous gown, and highlighted Rarity’s talent with finery. A fine lace collar opened around her neck and chest, allowing Rarity’s naturally slim body to show off the curving nature of the dress.
Head high, eyes half-lidded, and a lovely expression on her face, Rarity took two steps before Starlight’s spell began to do it’s work. Starlight couldn’t stop a manic grin from blooming on her face, and watched with bated breath to see what happened next.
The spell Starlight cast wasn’t one that took away Rarity’s elegance or grace. It didn’t spoil her clothes or her mane or tail. It didn’t do anything as plain as all that. It was an old spell, one originally used to punish ponies who had done wrong. Starlight had altered it from its original purpose, changing it so completely that she doubted anypony would be able to recognize its roots, thus speeding along any recovery Rarity would be expected to receive after today.
The spell was attuned to pony’s attention. The more ponies were watching the target of the spell, and the more they were the center of attention, the more weight the subject would gain. It was clever, and Starlight was still proud about how she’d thought of it.
Rarity’s world may have been a stage. Here, with the paparazzi and elite watching for the ponies worth their time, Rarity would receive all the attention she had always wanted. Starlight had been sure of that when she picked this event to spring her trap, and she wasn’t disappointed.
There were several hundred ponies in this room, with all their attention focused on the catwalk in the center of the hall. All that attention was already having an effect on Rarity’s physique.
Slowly at first, then gaining speed, Starlight could see Rarity’s plot and flanks expanding under the dress, causing the once draping fabric to tighten and bunch together as Rarity walked. Rarity’s walk down the long catwalk hitched for a moment, but she visibly took a breath and continued. Her experience in the fashion world was clearly telling her to keep going and not make a scene.
Halfway down the catwalk, Starlight could see how the tight bodice was making Rarity’s problem more..acutely noticeable. The open collar and the lace was pressing so tightly into Rarity’s neck and chest that the expanding flesh resembled an overfull bread pan in the oven. Her gait had slowed even further, confusing some of the models behind her.
Most of why Rarity had slowed down was due to how tight her dress had become. Flesh bulged out from under her sleeves, and judging from her waddle, the tight garment was restricting her range of motion.
A loud ripping sound preluded to the garment failing. The seams across Rarity’s flanks ripped apart, allowing her plot and flanks to sag free now they were unrestricted. That failure led to the rest of the dress to rip apart, falling to the catwalk.
Free of the constraining fabric, Starlight could fully see the effects the spell was having. Ponies were shouting, and Rarity looked overwhelmed. However, she knew the best thing to do was to not make a scene. Naked, Rarity still made her way down the catwalk. Nopony would be able to say she hadn’t reacted well under pressure.
Rarity’s stomach bulged out, hanging to her knees and still going. Her barrel was wide, supplying a base for her stomach to hang off of. Her plot and flanks were twice as wide as her barrel, threatening to overhang her hocks as she moved. Her legs were thick, jiggling with every movement she made. Free from the collar, her neck and chest had bulged outward. She had two chins and a third one was on the way.
Whispers and chatter had started among the audience, and the models behind Rarity had stopped their progression down the catwalk. They were frozen, staring at the sight in front of them.
Rarity didn’t seem as calm as she’d had before, her resolve crumbling as her walk slowed to an awkward waddle. Before Starlight’s eyes, Rarity’s stomach inched lower and lower to the ground, spreading out wider as her barrel did the same. Rarity’s waddle slowed and became more pronounced as she struggled to get her legs to move around her bloated stomach.
Rarity finally reached the end of the catwalk, panting for breath and tears streaming down her face. Her mane was untouched, but her tail and makeup were ruined. The tail was caught in the rolls of her magnificent rear, frizzing and ruining the curling job.
Rarity choked back a sob, turning around so she could get backstage. However, after another step, her stomach finally touched the ground. The end of the catwalk groaned audibly, and those seated near it scrambled out of the way seconds before it collapsed. Rarity fell heavily on the remains, shaken but seemingly not injured.
She tried to get up, but she could no longer get off the floor. Her hooves didn’t reach the ground.
Pandemonium broke out, as some ponies did their best to try to give Rarity more space. She’d yet to stop expanding, her girth slowly eating up the evidence of the catwalk underneath her. The models had fled the catwalk, going backstage.
Still, Rarity was being watched. She was still the center of attention. Now she was grounded, Starlight could really see how quickly Rarity was gaining. The doors finally opened, and ponies started to stream out as emergency services began to make their way toward the immobile, sobbing Rarity.
By the time the team got to Rarity, her desperate attempts at moving had slowed to pathetic wigglings as her legs became so bloated with fat that she couldn’t move them very well. As the paramedics tried to understand what was going on, unable to help Rarity in spite of her pleading, Rarity quickly developed a fourth chin and a thick set of jowls. They squished together with her multiple neck rolls, the sensation sending Rarity deeper into her hysterics.
Starlight began to make her way to the doors, still keeping her gaze focused on Rarity. When Starlight moved out of range, the spell would fade in intensity before fizzling out completely in about an hour or so. Starlight wanted to get as much pleasure from this experience as she could.
When Rarity’s dainty hooves were sucked into the fat of her leg rolls, Starlight finally decided to leave.
Let’s see Twilight try to fix this now. With a self-delighted cackle, Starlight finally left the still sobbing Rarity in the hooves of ponies who clearly didn’t know the first clue of what they were dealing with.

I blame Caifu on the weight gain Discord server I'm on. Not sure if this is what you had in mind but hey I gave it a shot.
This was fun. Different than my usual.
