A Princess has many obligations, one of them is gaining huge amounts of weight...

Twilight had been struggling, she was lagging behind her enormously fat peers. Celestia, Luna and Cadance all weighed far more than she did. It had been years at this point, but Twilight's busy schedule had just kept her from gaining like they had. At least, up until now.

The Princess Problem

“You know, I can’t remember when all four of us were in the same room together at the same time. It has been a while.”

The words of Princess Cadance rang true between all of them. Twilight, Luna and Celestia all sat for a moment thinking. None of them could remember the last crises that had brought them all together. This however wasn’t one of those times. As the four sat together, Twilight couldn’t help but shuffle nervously. It was always intimidating to be around what she considered her betters, but when all three of them hemmed her in like this it was even moreso.

It had been decided long ago between the four of them that a physical embodiment of wealth, prosperity and power would be most beneficial to the four Princesses and also the nation of Equestria. If their leaders were shown to be properly looked after at a mere glance, then the populace would be able to rest easier. It was a placebo almost, but once the plan had been put into place, like most it had worked. The nation had prospered greatly since the great gaining had begun.

Right now, after a number of years of gaining, three of the four Princesses had reached enormous sizes. Celestia, even the enigmatic leader was the largest of all. Weighing over two thousand pounds of pure lard the enormous mare was a sight to behold, her huge white stomach an enormous bed of lard that supported her hefty frame and jiggling body, backed up by two orbs of blubber behind her that were on the verge of swallowing her tail which flicked from side to side trying to avoid getting stuck between those monstrous cheeks.

Luna and Cadance were never far behind, weighing in at around two thousand pounds each as well, they confidently had taken to the larger sizes as with little trouble. Luna, a deep blue lard ass of a Princess kept trying to catch up to her sister, always just a little behind. Cadance, looking like a bloated pink elephant had gone at her own pace, still managing to embody the large satisfied persona that they all aimed for. All of them had done well, except Twilight.

It had been six years since she had ascended to the throne as Princess of Friendship and all that time, she had hardly gained a pound. Twilight had checked, daily. She had tried desperately to pack on the pounds as her longer serving peers had but her busy schedule and hectic lifestyle meant she struggled. Anything she gained was quickly shed as she scurried around in her duties. When she did get a chance to eat, she was often interrupted or just didn’t have the time to properly sit and fatten herself. In those six years she had hardly managed to gain much, weighing in herself at three hundred pounds. To be with the other three, especially Celestia who was so much bigger than her was...intimidating to say the least.

“Indeed...hmm. I certainly cannot recall. No matter.” Luna spoke, shifting her weight slightly. All three of them were leaning their stomachs on plush cushions to support their weight, except Twilight who was simply sitting on hers.

“Twilight? Still looking as thin as ever I see.” Cadance said.

“I know…” Twilight replied, simply sighing. She bowed her head down and rested in the pillow, obviously slightly hurt by the comment.

“Come now Twilight, I only joke. I know we all agreed to gain all those years ago but it wasn’t mandatory. Besides you’re busy.” Cadance continued.

“I know, that’s the problem Cadance. It’s been years, years since we all decided on this and look at me. All I’ve managed to gain is a pathetic amount of pudge…” Twilight moaned, giving her tiny stomach a little push with her hoof to emphasise her point. “It’s not like I don’t try, really, I do. I want to be as huge as the rest of you. But either I can’t eat my fill, or when I do, my busy schedule means I lose it rather quickly.” she lamented, spilling her woes for all three to hear who listening intently. “What am I to do? Even if I started now I’d still be far behind. I tried plenty of things, but nothing worked.”

“Yes, I can see your problem Twilight.” Celestia said, shifting her frame slightly. “But we’ve been talking, we think we have a solution.” the Princess said with a coy smile, her horn glowing the familiar yellow it did when she worked her magic. In front of Twilight, as if from nowhere, a large box appeared. Rather plain in appearance, she opened it up, curious, to reveal a number of pastries inside. They all glowed faintly with three different colours, the same colours of magic that Celestia, Luna and Cadance all used for their spells. Twilight levitated one up, inspecting it closely.

“I’ve tried eating things like this, it’s never been too useful.” Twilight said, eyeing the floating treat in front of her eyes. The one she had picked glowed blue, obviously from Luna’s magic.

“These are different.” Celestia explained. “Each of us imbued them with a spell, a powerful one. Try it. I promise it won’t be bad. Only for your figure.”

Twilight didn’t need anymore prompting, she ate the pastry in but a few mere moments, taking large bites out of it. The treat was rather tasty, quickly passing between her lips and slipping down her throat. It was sweet, but not too sweet. She licked her lips.

“Delicious…” her voice trailed off, below her, Twilight observed her pudgy stomach visibly push out. That had never happened before. She felt heavier, trying to stand and giving her new fatter form a wobble she estimate the treat had gained her around fifty pounds. She had to ask. “What have you done to them?”

“The treats?” Luna replied. “Just a little magic. We know you want to be as huge as we are Twilight, it's been obvious from the start. We figured this would just help you along. Don’t be shy, have another…” The Princess teased, levitating another pastry from the box towards Twilight's lips, which Twilight herself grabbed herself out of the air with her own magic and started to quickly eat.

There was something about these pastries which was different, beyond making Twilight just want to eat more and more. She was starting to feel...aroused. Her marehood tingled in anticipation of what she thought she might become. She had always looked up to her mentors, Celestia more than the others and well, Cadance was always more like a sister but she respected them all in different ways. It had crushed her when she just hadn’t gained like them, now she had the chance to atone, she felt excited. This was only pushed on by encouraging words from her peers.

“That’s it Twilight, go on - have another. You want to be as big as us don’t you?” Celestia teased slightly, levitating a few more of the pastries out the box towards Twilight’s greedy lips. “We know you’ve wanted this for a long time, so why hold back? We’re offering you the chance to join us, even more so than you have already.” Celestia continued, shifting her bulk slightly closer to her prized student so she squished her flab into her to give her a small taste of what was to come.

“Indeed Twilight, this has been a long time coming. By the time we’re done, you’ll be as big as us, maybe bigger…” Luna said, now taking her turn to speak and feeding Twilight more of the pastries as she herself dug into the box with magic and lifted a number out. It seemed the words of the two of them were easily spurring Twilight on, having eaten a large portion of the treats already Twilight could feel her mass gaining. Each one added a whopping 50 pounds of blubber to her body. She couldn’t stop, the treats were just too good. The mare could feel herself visibly swelling in size as she ate each one faster and faster, the fat on her body piling on as she began to form a belly bed beneath her. Huge squishy rolls of fat were starting to form on her stomach as Twilight started to get towards four figures in her weight, and the Princess’s weren’t done yet.

“Imagine what the public will think of you when they see you like this Twilight.” Cadance said, picking up a treat with her hooves and gently wafting it in front of Twilight, the treat itself only lasting in that state for a few seconds before the greedy purple Princess couldn’t resist but reach out with her magic and take it from Cadance. Whilst Twilight chewed, the Princess giggled.

“Now now, that wasn’t very Princess-like behaviour Twilight.” Cadance cooed slightly, picking up another pastry for the greedy Princess but this time letting her take it with her magic. Twilight hardly said a word, too focused on consuming as much as she could as fast as she could. She was loving the feeling of fattening up. She had no idea why she hadn’t done this sooner, it was heaven.

Every treat, every bite. She was making up for as much lost time as she could. She was eating more than she ever had before.

“It is wonderful to see her eat a full meal.” Celestia said, now sure Twilight was so lost in her own fattening body and the sensation the treats were giving her that she spoke freely to her fellow Princesses, as if Twilight wasn’t even there.

“Indeed, where did you find the recipe for these anyway?” Luna enquired of Celestia, leaving Cadance to continue to feed Twilight. She seemed to be enjoying it anyway.

“I didn’t, it was Kibitz. He tells me he was in one of the quieter wings of the royal archives trying to work out a more advanced schedule for my eating when a cookery book caught his eye, a magical one. The spell for imbuing a number of treats like this was inside. Each had varying results on the amount gained, or so the book explained.” Celestia said, magically levitating a couple of the pastries towards her and Luna.

“Let me guess...the pastries were the ones that added the most weight.” Luna said, taking a bite for herself of the treats, Celestia joining her in doing so.

“No actually, there were more fattening things. But I wanted Twilight to enjoy her uhm, ascendance, I suppose. Rather than it just being over in a few bites. A big box of delicious pastries from the finest kitchens in the castle magically imbued by us to get her to where she needs to be seemed appropriate.” Celestia said, taking a moment to stop her explanation whilst her and Luna both munched on the sweets. They watched as Cadance took one too whilst she continued to make sure Twilight kept eating.

“So many though...if she eats them all, she’ll be double the size we are now!” Luna said, taking a few more of the treats for herself and her sister. “Should we even the odds?” she asked Celestia with a grin, already biting into another pastry.

“Mmm, perhaps I did overdo it. There’s a bit more here than I anticipated. I think when I told the chefs these were for Princess Twilight they worked harder than ever, as keen to see her fatten up as much as we are…”

All the time the two had been talking Celestia’s eyes had been on Twilight, she observed the fat mare shift her weight. She was over one thousand pounds now easily. It was usually obvious when a pony got to the four figure mark because their stomach formed such a mass of blubber underneath them, they had no choice but to move into the most comfortable position - that happened to be using the stomach to support the rest of your body whilst eating. Celestia, Cadance and Luna were all somewhat larger than Twilight to start with, so that didn’t happen until later, but Twilight seemed to be coping well. Celestia watched with pride as she observed her student shift her enormous weight, that gigantic gut spreading beneath her as she leaned on it to continue eating. She grinned, turning back to Luna.

“But yes, at this rate she’ll be finished before we’ve started. Keep the pastries coming sister.” Celestia said, Luna already making sure the two had a small pile from the box for themselves.

Twilight herself was just eating endlessly. Every one of the treats she consumed she could feel such a huge amount of fat being added to her frame. The excited mare was letting Cadance feed her at this point, the treats now each just being levitated into her waiting maw. Each of them was vanishing in mere seconds, she had gotten into a comfortable eating rhythm that she was enjoying. Perhaps just a little too much.

With her hooves, she felt down into her mass, gigantic stomach beneath her just pushing forward like a surging tide of fat that was seeking out as much space as it could greedily consume itself. With a hoof she pressed into her belly, no folds, at least not hugely visible ones. She had been slightly concerned she’d just gain hundreds of unsightly rolls that would adorn her. Not the case, her stomach was nicely pushing out a smooth mass beneath her that was rounding out nicely. She felt so soft, so plush. Putting her hooves around her belly was like hugging the world's softest pillow. She hadn’t expected this, the feeling of it was just making her more lusty. If she got bigger, she thought she’d be even softer, what an enticing thought…

Behind her, the fat mare squeezed her thunderous thighs together for fun, wobbling her monstrous rear that easily jiggled behind her for amusement. It seemed her belly wasn’t the only thing that was gaining in size. Her flanks were taking on a good portion of the added gain, rising up like two small mountains that seemed determined to show off her huge, overly stretched cutie mark that covered her sides. Between it all, she could feel her lower lips being squished and squeezed between her mass. The sensation of all this around her was starting to very much get to Twilight, her now double chins quivering with the rest of her in excitement as she ate yet another pastry.

“Hmmm, you know she’s really getting into this.” Cadance mused, her words making their way over to the ears of Celestia and Luna and she pushed another of the treats between Twilight’s lips.

“How can you tell?” Celestia asked.

“...Princess of love? I can always tell. Besides look at her, she hasn’t said a word.” Cadance simply replied, shifting her mass a little more towards Celestia and Luna as all four Princesses gorged themselves on the treats. The three of the grinned at each other, taking more for themselves.

Celestia knew she had a lot more in her. The Princess had been giant for years now, but she had become comfortable with her size. The slow and gradual gain, unlike Twilight's, had meant it hadn’t been hard for her to just keep getting bigger and bigger. Like Twilight, she had been apprehensive at first about what they had decided between them. But she had quickly grown to like it. There was something about a hefty full stomach and flanks that wobbled with a single step that was so enticing to her. She had no idea just how big she could get, her appetite seemed eternal like she was. She might have to draw the line when she could no longer walk freely, even now it was already becoming a struggle as she squished her own stomach fat beneath her, gigantic belly sloshing around.

Luna was like her sister, always slightly behind, but with the four of them all gaining together she was feeling better about catching up. She wondered if they might get together more for more of this, it was nice to not only spend time with the other three but also put on so much weight in one go. She had never considered that just simply gorging like this could be so divine, but here they were. Four utterly huge tubs of lard that only seemed intent on getting larger. She felt herself like a small crater, her gigantic stomach and huge flanks quite a sight to behold.

Cadance had embraced the increase in size far more than Celestia and Luna, although she had just decided to keep pace with each as to not outshine her peers. It was important that the royal sisters be seen to be the biggest. However Cadance had gained the fastest, easily able to pack on tens of pounds in a sitting. After these pastries, that now seemed somewhat like child's play. She wondered what Shining would make of her new size once she got home, he had loved every gain she had taken on up until now. Wait until she showed him her ballooned flanks and a gut that could crush a stallion at twenty paces, she giggled internally at the thought of his reaction.

“You know you really did a fantastic job with these Celestia.” Cadance said, licking her lips as she magically reached for even more. “They’re delicious.”

“Thank the kitchen staff, we only did the magic.” Celestia herself said. The three of them were eating quite a few pastries, Cadance looking at them all estimated the three of them now weighed around two and a half thousand pounds. Twilight was catch up though, her bulk meant she was about to break two thousand. She was just getting to the size the three of them had been when they started. Cadance shuffled her mass back to Twilight, her massive gut sagging beneath her as she pushed it along the floor. For the first time in what seemed like an age, she gave Twilight a small break from the treats.

“You know there’s still quite a lot of treats left Twilight. Just how big do you want to be?” Cadance asked, again picking up a couple of the pastries and gently dangling them in the air whilst the greedy Twilight tried to form a sensible answer, but none came to her. Instead from her crumb covered lips she just said.

“B-bigger than all of you.”

There was a small amount of giggling from the trio of Princesses, Twilight herself going rather redder than she always was. Was that a mistake? She was worried, she didn’t want to overstep her bounds…

She was relieved then when Cadance simply pushed more treats her way, delighting in just how much Twilight was now enjoying herself. “Then bigger you’ll be.” was what she said.

More treats it was then for the four of them. Twilight couldn’t help but feel around her bulk once more, it had grown so much in such a short time. She couldn’t believe how massive and hefty she was. If she tried, her stomach was so huge and enormous that her rear legs were now having a hard time reaching the floor so she could stand on her stomach. She was fairly certain only her gigantic rear was what was weighing them down behind her, acting like a pendulum of fat that swung her hefty body downwards towards the floor.

She tried to flutter her wings a little, useless. It was curious too, at least to her. She had noticed it on Celestia, other Alicorns and Pegasi. The wings seemed to act like another area for her body to collect the fat she was piling on. Fat, hefty and now utterly useless wings sat splayed on her back. She hadn’t seen any of the other three fly for quite some time, now she knew why. There was no way those wings were ever getting her off the ground again.

To top it off, her stomach below her was not only one giant glorious bed of blubber, it was a bed she was starting to sink into. Already she could feel her forehooves resting nicely against the squish of her body. Twilight was embracing the greedy nature of her eating and couldn’t resist even more play with her stomach, fat squashing between her hooves. She moaned, red faced and slightly embarrassed to be letting herself seen this way in front of the other three, but at this point she didn’t seem to care so much. The food was taking her over.

The four continued to eat. The box of pastries now looking shamefully low. The four Princesses had done rather well and managed to eat their way through a small mountain of magically enchanted food. At this point, there was but a small selection of them left, glowing the three colours of magic they had been enchanted with.

“Hmmm…” Celestia paused for a moment, picking up the last of the treats with her horn. She felt fatter than ever, she couldn’t imagine what Twilight must be feeling. She had gone from being just slightly pudgy to being a small mountain of a mare. “I think the final ones are for Twilight, let's give her one hundred and fifty pounds of pleasure, shall we ladies?” Celestia enquired. The three took one each, it was almost symbolic in a way, that the session should end like this. Celestia, Luna and Cadance all took one of the treats in their magic and then all at once stuffed Twilights maw with them together, not holding back. Twilight herself shuddered, feeling her cheeks bulge out as they tried their best to fit in as much of what the Princesses were feeding her with as she started to chew the final batch.

It was enough, enough to fully push Twilight over the edge and make her blush deeply. As she let go of her enjoyment of the gain, juices flowing down her stomach as she squished and squeezed her wobbling, jiggling rear and fat belly together she panted in a lusty, bloated release that felt like heaven. She was such a lardass, a total fatty. The four of them having coming close easily to three thousand pounds between themselves now, Twilight herself so big she was easily verging on immobility at her gigantic size.

It took her a moment to collect herself, whilst she did, Celestia cleaned up the remains of the food and poofed the now empty box out of existence. She had only one question for her prized porker of a student.

“How does it feel Twilight?”

“A-amazing...I’ve wanted this for so long…” was all she said at first, still coming down off the high of the gain she had undergone. Composing her thoughts she spoke more rationally. “I never thought of magically enchanted food, I…” her words were cut off as her stomach beneath her let out a gigantic bloooorrrrppp as she shifted around on it, her movements only encouraging cute noises from her belly that echoed around the room. She blushed again.

“Don’t worry, that happens, especially at your size. Go on.” Celestia said.

“I suppose I just want to say thank you, for giving me the opportunity to finally be a real Princess.” was what she finished with. The other three just smiled at her, they knew they had done well. Twilight was now just as big as them, and she’d continue to gain having had such a wonderful introduction to being a bigger mare. The next words that came from her then was of no surprise, despite spoken softly.

“Is there anymore pastries?”
