[Weight Gain, Slob]

"Reimu! You need to go on a diet! You can't keep sitting around all day!"

That was the first thing that Komano Aunn had to say to the Shrine Maiden of Paradise, the moment that she saw her current state. She had been noticing that Reimu had been starting to be a bit lazy and growing more than a little flabby thanks to all of her visits to the Scarlet Devil Mansion. Which was why she had also tried to keep her home.

Unfortunately, she hadn't been checking on her every time that Sakuya and Remilia went to visit! So she completely missed the part where Reimu turned into a mountain of lard! No, wait, that was the green-haired Shrine Maiden. That one had also grown fat, probably due to exploiting the workforce that had become part of the Youkai Mountain.

Still! Reimu had grown far, far, far, far too fat! She was so big that she couldn't really move at all! And Aunn wasn't strong enough to push her either, so she was almost always stuck outside! That was fine in the summer, but winter was rapidly approaching!

That was why Aunn was pushing her towards trying to diet. Not just because it'd be healthier for her, but because she'd not freeze! Even if her fat was really warm-

No, bad thoughts! She had to help Reimu diet! No thinking about how soft and squishy and warm and nice Reimu was to touch and rub up against- Nope, no no no!

Reimu gazed slowly and drowsily towards Aunn, the Komainu trying so desperately to get her attention. But she didn't really listen at all. All she really heard from her yapping mouth were the sounds of a dog trying to cry out at her. Which was its own kind of annoying, not that she could be bothered to do anything about it.

"Look at you, Reimu! How are you going to solve incidents like this? How are you going to stop the youkai that want to cause problems? Marisa can't handle everything! She's already just as fat as that library, and the Dollmaker's busy taking care of both of them! You want to be just like her?" Aunn cried out, trying to make her focus on her duty and how important she was in the grand scheme of things...

Only to be met by a loud belch, the gas inside Reimu violently erupting from her lips. The force of which caused the shrine itself to shake. Which was insane to see and think about. The fact that she had not only grown so fat that she could barely move, but also so potent in terms of what she was capable of like this that she just... Started to affect the world around her...

Forget getting sick and cold in the Winter, if she kept this up... Would she turn into some sort of Youkai because of her intense gluttony? That wasn't allowed! Reimu would probably exorcize herself, if her past self saw what she was becoming..!

"Reimuuu!" Aunn cried out as she pushed up against that big belly. It was nearly as big as she was, and it was sooooo soft. So soft that she almost wanted to lay her head down on it and just drift off to dreamland and just... Juuuust...

No! Bad Aunn! Soft bellies weren't the way! Keeping Reimu healthy was the way! But how was she going to make her diet? She had to... Had to...

A sweet scent worked its way into Aunn's nostrils, causing her to rapidly climb that belly to try and find the source of the smell. And there it was. Laying neatly close to Reimu's surprisingly stocky bosom. A little snack that had been left behind since the last time she indulged...

Reimu had gotten so lazy and so slobby that she was using her belly as a tray! A table, even! The crumbs on her belly, combined with the juices and the sweat... Just how often did she use her belly like this? More importantly, how long had this been going on for..!?

She had to stop this. She had to. What could she do to stop it? Probably feed Reimu better. So the first thing she had to do was reach up towards that food, no matter how sticky or slippery or dirty her belly might be, and then-

*URP-*

Reimu let out another, slightly smaller belch. And as a result, her big belly started to wobble and sway. Causing the treat that was laying on top of her belly to roll down towards the komainu that was trying to get up onto it...

Not just roll down towards her, however. It was rolling straight into her mouth. Landing straight on her tongue before she had a chance to realize what was going on, leading her to swallow it way before she could even try to stop it. And once she swallowed it...

Aunn could feel her entire body simply being overwhelmed. Not by energy, despite the insane amount of sugar pumped into the construction of the treat... But rather by sheer laziness. When food tastes that good, you'd simply want more. More and more and more...

But there was no more on Reimu's tummy. And she barely even paid attention to what Aunn was doing. In fact, just the act of breathing was a lot more taxing for Reimu. Constant gasping and panting for air thanks to how much she had already consumed, as her belly went to work trying to digest it all... That was what she was really focused on. Not the Komainu trying to make her diet...

Aunn's tummy grumbled and grumbled. Not nearly as much as Reimu had, but that single taste of pure sweetness had started to drive her more than a little mad with need. So she headed straight into the shrine. There had to be more sweets... More treats...

She couldn't wait until Remi and Sakuya got there. She couldn't. As much as she'd probably enjoy being spoiled by them too, given the subtle happiness on Reimu's young face, even marred by all of that flab that had packed onto it... She just wanted to satiate her need right now..!

Thankfully, she was rewarded. There were so many treats hidden inside of the Shrine. So many that were either partly eaten or hadn't been touched. A sign of how gluttonous Reimu had become, and how far she had fallen in the process...

But she wasn't focused on that. She really should be, considering how important the Shrine Maiden of Paradise was. But instead, Aunn's belly was the thing that dominated her. And it craved more. No matter if the food had been tasted already, or it had just been left out by an unobservant fatty...

Aunn ate and ate. Down on all fours like a bit of a rabid animal. Letting her newfound gluttony carry her. Even as her belly pushed against the floor from how much she had eaten. Even as she felt her tummy grumbling and grumbling thanks to how much she was pouring into it, and how much her belly both craved more food and how difficult it was to digest so much food in one fell swoop given that she hadn't been a heavy eater before...

Before long, Aunn ended up on her back. Not because she was done eating. Far from it. There were still so many sweets hidden inside the Shrine. So much that she had to dig through. But all she could do was lay there.

With her belly sticking out into the air. Such a big belly, firm and stuffed full of treats. On such a small body like hers. It wasn't as big as Reimu's yet, but Reimu's body was also a bit of a wonder. She was able to digest and convert fat at an astounding rate... Which was also why her growth was so astounding, and why the girl's lack of exercise and eating habits had caught up with her...

Aunn, on the other hand? She could already feel her body growing bit by bit. She could feel the fat being transferred from her belly onto her upper arms. And her thighs. And her chin. All of it started to pile onto itself as she panted and gasped, hands struggling to reach her belly bit by bit...

It wasn't shrinking. Neither was her hunger. She wanted... She wanted...

More... Moooooore...

Aunn was a lucky kind of girl. Because she was a Komainu, she had a second body. And while they were both Komano Aunn, there was a tiny layer of separation between the two of them. While they probably should be identifiable as the same person, there were enough small differences between the way they thought that meant that they could be called sisters if one looked at them both at the same time...

Something that was especially true at the moment. Because the other Aunn was being forced by her fattened self to get them more food. Something that was even more exhausting than normal, because they shared the same pool of stamina. So the much thinner, much slimmer Aunn was the one that ended up bent over and struggling to breathe after a few steps...

The very same Aunn that was currently taking several sips from a portable drink that Sakuya had given her when she was off getting Reimu and Aunn's food. It was something that the unmoving library abused to keep herself hydrated. Something that Aunn couldn't stop drinking from. It made the walk to the shrine bearable. Even if she had gone through a couple by the time she passed through the shrine's gates once more...

And as she made it all the way over to the shrine, she was not happy to see her other half. Nor was she happy to see how big Reimu was, because it only reminded her of how her other half had failed to make Reimu diet...

Though it didn't make her nearly as frustrated as seeing the other Aunn currently being even bigger than Reimu was. Not only that, but she was laying on the ground. Right in front of her 'owner'. Like a lazy dog would. Something that made Aunn even more annoyed. She should be guarding the shrine, not sleeping..!

"Stop... Stop doing that..." Aunn muttered as she put the food down in front of the two fatties. She could feel the exhaustion of walking all the way here wash over her. She didn't have the energy to fly, so this was the path she had to take. Which left her just... Just on the verge of passing out from all the energy she had spent...

Reimu didn't react to what was being said. Nor the food that had been put down in front of her. All she did was breathe like the slob that she had become. How utterly sad to see, considering what she had been just a little while ago...

And the other Aunn was no better. She was still able to move to a certain degree. But instead of trying to use that movement to try and make her butterball of a Shrine Maiden try to lose weight or try to stop eating so much, she simply reached her arms out towards the bag of treats that had been put down in front of her.

All while panting and gasping like she couldn't breathe. It was very hard for her to breathe. Even more so because she was exerting herself. Wheezing, as the sweat poured down her body and into her incredibly ill fitting dress...

Seeing that flabby belly that was nearly twice as big as Aunn herself was, with most of it poking out under her otherwise tight dress... It was humiliating for the slimmer Aunn. She didn't want to keep seeing this. She didn't want to...

But the more she saw it, the more her own belly started to growl and groan. But she tried to keep it at bay by sucking down more of the fruity juice that she had gotten from Sakuya...

"Fooood... Waaaant..."

The other Aunn's voice was hard to ignore. Especially since she wanted the exact same thing that Aunn wanted. She wasn't ashamed to admit it. Unlike the girl that was trying to ignore the sound of her wanting food...

Aunn tried everything to ignore all the food that she had brought. It was difficult. But she was satiating herself with the... the...

...

Her juice had run out. And she couldn't stop herself from dropping it and trying to reach into the bag once she had lost something to drink. She wanted something to munch on. Something to satiate the growing need inside her. Something. Anything..!

Aunn quickly grabbed her needy arm. Trying to pull back on it to try and contain her gluttony. She was like a needy dog in that way. She was almost consumed by her instinct to eat and eat and eat...

But she had to hold strong. She had to avoid becoming as much of a fat little girl as both her other body and Reimu had become. Even if they did look... Even if they did look really comfortable...

"Eaaaat... You'll looooove it..."

Aunn's eyes widened slightly. She could hear a voice in the back of her head. Or was it on her shoulder? She couldn't tell. All that she could tell was that her stomach was growling even more than it had been before. And she really wanted to listen to the voice...

If she were to try and turn her head over her shoulder, she'd be able to see what was trying to tempt her. It was a tiny Aunn. A tiny ball-shaped Aunn. Because it was the voice of the other Aunn. Speaking into her mind, just like a devil would. Tempting her to sin just as badly as she had. Tempting her to become a glutton...

There was no angel on the other shoulder. There was nobody that would try and push Aunn down the right path. Because she was the one that had to try and push both of the other fatties down the weight loss path instead. It was two against one in that regard...

Especially as she managed to catch a glimpse of the needy look in Reimu's eyes. She wasn't able to reach out for the food like Aunn was. But that didn't mean she didn't want it. If anything, it only made her attempts to stare towards it feel that much more desperate. Like there was no single thing in the world any more enticing than all of that fatty food...

Aunn tried. She really did. She tried to fight against the voices that were trying to make her just as fat as them. But she was just one girl. And one of the voices was her own voice.

She fell onto her knees. Panting and gasping. Drooling like mad. As she picked out treat after treat from the bag. Some fully cooked meals that Sakuya had found a way to keep preserved. Some extra sweet things that were meant for a quick snack. And some that were just meant to be casually eaten throughout the day...

All of them went down the green-haired Komainu's mouth. She didn't think twice about what she was eating. She didn't think twice about eating in the first place. All that she thought about... All that she thought about was filling her tummy with all the food she needed.

The other Aunn was a little disappointed that she wasn't the one that got to eat. But it didn't matter what she thought. Nor did what Reimu was thinking matter. The only thing that mattered right now was the Komainu's own need. The only thing that mattered was her tummy and how much it was making rumbly grumbly noises..!

She ate and she ate. Going from eating in a more civilized manner, before she ended up on all fours and dug in like the dog she was. Eating whatever came her way. Using the bag like a bowl, all while her belly grew bigger and bigger...

Even as that belly of hers ended up so big that she could balance herself on it, she ate as she could. Only when she ended up so big that she couldn't paddle her way towards the 'bowl', did she end up finally stopping...

Rolling onto her back. Just as the other Aunn had done when she had finished digging into everything. Panting and gasping, as it rapidly became harder and harder to breathe. The mere act of breathing was difficult for her, not just because of the other Aunn this time...

She was becoming a butterball. An obese little girl, just like Reimu and the other Aunn. And she'd fit in with them. She was already laying at Reimu's feet after all. She was just going to be as big as the two of them. No big deal...

The last vestiges of Aunn's mind were telling her that this had all been a terrible idea. They were telling her how much she should be regretting this. But she didn't listen to them. Of course she didn't. There was no way that she would ever listen to that kind of voice ever again.

Her gluttony had won. Just like it had won over Reimu. Just like it had won over Aunn's other self. The three of them were obese, sweaty slobs that couldn't really move unless they really tried. They were completely codependent on others...

Almost as if on cue, they could hear the sound of vampiric giggling in the air. And the sound of heels clicking against the stone stairs leading up to the shrine.

Remilia and Sakuya were here to feed them. They were here to make them sink deeper. Sink even further than they ever had, with no chance of ever thinning back up...

The Komainu and the Shrine Maiden of Paradise simply drooled in anticipation, abandoning everything to their gluttony...
