[Weight Gain, Obesity, Harem]

Hakurei Reimu. The Shrine Maiden of Paradise, and the Hakurei Shrine's sole Shrine Maiden. It was up to her to keep the Shrine safe and the worship plenty, while at the same time ensuring her own livelihood. Not only that, but the act of cleaning up Youkai Incidents was also something that fell to her. Which left her an incredibly busy girl from time to time.

"Reeeimuuuu! Where's the saaaaaake!"

Reimu sighed as she heard a distinctly drunk voice call out for her. She knew exactly who was calling for her. Because despite the fact that she was the lone Shrine Maiden, that did not mean that there weren't others that called Hakurei Shrine their home. Or used the place of Human Worship as a place to loiter and have fun, specifically because of her.

"I put it in the storehouse, Suika. And I locked the door. Don't break it, or I will exterminate you."

Her sharp gaze turned towards one of the most frequent guests. The Oni, Ibuki Suika. Perpetually drunk, and the cause of one incident prior. And yet despite that, she ended up lingering by the Hakurei Shrine. Mainly because fighting against Reimu had been fun, and the Shrine made for a great place to party after any incident.

At least, that's what she had been for a good while. But... How long had it been since Suika started to carry around that gut of hers? That distinctly heavy gut that sloshed around, audibly so, and kept her from taking advantage of her ability to change her size?

Reimu was doing her best not to stare at it. Observing a female's overweight body was deeply humiliating to the overweight female... At least, that's how it worked for Humans. She had noticed it when she caught the Ordinary Magician sneaking out a few too many of her snacks. The trap she had placed for that rat had paid off, though she had to admit that she felt a little bad as she watched the Ordinary Magician struggle to get back on her broom and fly off after she packed on those pounds.

Suika, however? She just laughed off the humiliation. Youkai had no issue with their bodies. If they grew fat, or outright obese like Suika had, where the pudgy parts of her form were not constrained to her torso, creeping further out and turning her limbs to proverbial sausages with how much flab had packed onto them... It was just something that happened to them. They wouldn't be bothered, not in the slightest. If anything, they'd just eagerly continue down the same path that ended up making them fat in the first place.

"Ehhh? Why would I break your stuff, Reimu?" Suika laughed, very clearly intoxicated given the massive red hue on her face. "Saaaaay... Couldn't you unlock it? I promise I won't drink aaaallll of it..." She was trying very hard to try and sound convincing. Trying her best to seem like she wouldn't cause trouble. But this was coming from one of the most notorious Youkai, on top of coming from an Oni...

"No." Reimu immediately shot back, as she continued to brush away a few leaves that were currently resting on the ground. All while sighing as she let the autumn wind blow past her. It wasn't as cold as last year... Or was she just warmer..?

"Ehehehe... C'mooooon. I won't do anything baaaad to the saaaaaake." Suika chimed, right before going on the offensive and jamming her hands forward, right around Reimu's waist...

All so she could sink her young fingers straight into Reimu's tummy. A tummy that was nowhere near as large as Suika's, and yet it was still distinctly plush. So much so that there was plenty for Suika to squeeze into. And this was totally fair game in her mind, considering the kinds of games that the Oni played with her kin...

Reimu twitched a little, a blush working its way onto her cheeks. She mustn't react adversely. That was what she had been taught. No outbursts. She could get angry, yes, but if it was in response to something cheeky like this, she must remain calm. "You won't get anything out of playing with me, Suika. Just give up and go sleep. Even if you're an Oni, you won't like the sluggishness that comes with waking up after drinking."

"It'll be fiiiiiiiiine. It's not like I'm gonna be any more sober when I wake up, haha!" Suika ignored Reimu's warnings, giving her cute chubby belly another clap or two, before grinning widely as she remembered something. "Maaaaybe... You'd like to try playing with me instead, Reimu? Would that make you change your mind? Just having your cute human hands fondle my big belly?"

Reimu paused. She didn't turn to face Suika. Not even as she heard the obvious sound of the short Oni sloshing her belly around. No, she didn't need to turn around to imagine what was happening, especially not as she tightened her grip on her broom and tried to think of anything else.

But it was impossible not to. It was impossible not to imagine the Oni's youthful body. That adorably tiny form and how it had been wrecked by the weight she had gained from drinking so much. Even just drawing breath was enough to make her body wobble and tremble. It was begging to be played with. Made a complete mess of... And here she was. Asking Reimu to do it. In exchange for sake.

She had to stay strong. She had to avoid giving in. She remembered the tall tales that had been told of prior Hakurei Shrine Maidens. Most of them ended up cozy with Youkai for one reason or another... And before long, they abandoned the clan, never to be seen again. They left behind a successor, and nothing more. Some say that they fell victim to their needs and their wants, but none would know the truth.

"...You may take one bottle. No more."

Reimu relented. And Suika cheered, hiccuping mid-laugh as she scrambled towards the storehouse, knowing that she could get in with ease even if she hadn't gotten permission. But the fact Reimu wasn't going to stop her was just going to make this next drink sooo much better.

Of course Suika didn't see Reimu watching. Of course she didn't see Reimu biting softly into her lip as she watched her jiggly and extra wobbly alcohol-filled belly waving back and forth. It was a wonder that she was able to keep that thing from bursting... and it was a delight to see it peeking out from the sides of her body, as it swung up and down and all around thanks to her brisk steps...

It was a close one. But she had avoided getting grilled over the way that she stared towards the Oni's fat form. She couldn't help herself. Suika was that distracting. But thankfully, she was the only girl that happened to nearly live on the Hakurei Shrine grounds. There was one more, but she was not only tiny... She was also currently asleep inside, no doubt with her bowl currently serving as a way to keep the light from waking her too early.

Speaking of, it was about time for lunch, wasn't it? After watching Suika run around like that, without a care in the world despite how hefty her weighted tummy was... She could really go for something extra meaty herself. She should have that leftover meat from that stall. Maybe she could heat it up somehow, with that machine that Kourin sold her. If it even worked the way he-

"Ara. You're looking awfully red today, Reimu. Tell me, did you have any dirty fantasies? You can tell me, you know you can. I wouldn't tell a soul."

Reimu felt her heart skip a beat, before pure disappointment filled her soul as she looked at the blonde currently sitting on the steps leading into the Hakurei Shrine proper. Of course she had to appear. She did find that it was awfully suspicious that she hadn't shown up lately. But here she was, ready to make things terrible for her once again.

Among the many Youkai that populated and roamed Gensokyo, there were very few that were as important as the Sages. And the Sage that had been with Reimu the longest was Yakumo Yukari. To call her devious would be an understatement, especially with her power over Boundaries. It was why she had earned the nickname 'Gap Hag', one part referring to her power, one referring to just how old she really was.

Yet by looking at her, you would be hard pressed to believe that she really was that old. After all, she was currently in the body of a child that still needed to finish school. In fact, she was even tinier than Suika... Though not by much, as if she knew that Suika's body and looks had a certain effect on the Shrine Maiden.

"Not interested." Reimu said, as she tried to walk past Yukari. All while her eyes were magnetized onto her tiny body. Her adorably tiny body... Which was heavily contrasted by the thick fat that was packed onto her stomach, but much more importantly the rest of her body below the waist.

Yukari giggled as she watched Reimu trying to walk past, only to wink as the girl unintentionally walked straight into one of her gaps. And before Reimu knew it, she now found herself sitting on the very same steps that Yukari was, complete with the tiny blonde Youkai currently getting nice and snug on the Shrine Maiden's lap.

She was heavy. She was extremely heavy. And yet Reimu wasn't bothered. At least, she tried her best to avoid looking bothered. There's no way that she would want Yukari to have fuel for her teasing. No matter how big she grew, no matter how young she made herself look, she wasn't going to budge.

"Come now. We've been together for how long now? You can tell me, Reimu." Yukari chimed, as she made sure to nudge herself around on the Shrine Maiden's lap. Letting that fat ass of hers really get nice and cozy, while letting the subtler parts of her fat body jiggle in the process. She was going to tease her. Even if she didn't let her guard down.

In fact, she had taken this form specifically because she had noticed Reimu's interests. She noticed the way that Suika was allowed to get away with more and more tiny things as she grew fatter. Not only that, but she noticed that Reimu tended to be more favorable towards the younger crowd. This applied to those that only looked young, despite their massive age gap. Such was the case for the Scarlets, who had gotten much lighter punishments, and Remilia was one of the few previous instigators that Reimu was more than willing to work with after her incident had run its course.

That was why Yukari had fiddled a bit with the boundary between Young and Old. And she swapped her aging body out for one that was so terribly young. So terribly tiny... And then she packed the pounds on through constant meals that her dear Shikigami had made for her. Ones that would ensure that her growth was as effective as possible. All so she could continue teasing Reimu.

And it was effective. It was incredibly effective. Reimu was doing everything in her power to keep calm with Yukari on her lap. But the subtle hints that not everything was okay were clear as day. She was shaking. She was biting into her lip. She was squeezing her fingers into her own thighs. All for the sake of not falling prey to Yukari's scheme.

"Well then." Yukari smiled, pleased with Reimu's attempts to stay restrained. They were adorable. "If you're not going to say anything, then I think I'll just dig in." She chimed, snapping her hand as a gap appeared right above her lap, only to drop a nice and warm plate full of several pieces of reheated meat...

This was something that she had done before. Something that Reimu was forced to endure. Simply using Reimu was a chair of sorts, forcing her to sit there and watch her eat. After she had packed on all these pounds, after she had ruined her figure for the sake of furthering her plan to tease the Shrine Maiden of Paradise... She was able to pin her down with the weight of her body, and just indulge in her gluttonous urges right then and there.

Seeing Yukari dig in and eat was not making it any easier for Reimu. Especially not as the much smaller Sage offered her one of those pieces of meat. She wanted it. But she couldn't. She knew what would happen if she took the offer. Yukari would use that as a way to make sure that she would have to admit her interests. And though it was fairly obvious, though Yukari had long since figured it out, Reimu was not even close to admitting it out loud. Nor was she going to, because of the threat that this interest posed to the Hakurei Shrine as a whole.

Yukari ate. And she ate. As she had done so many times before. She made sure to grind her hips back and forth a bit. To try and entice her plump Shrine Maiden to try and stake her claim. To try and make her break her abstinence. If she broke it, then she would make sure that the girl who loved such young and extra fat bodies would get everything she wished for... All so she could have her wrapped around her finger for the future.

But no. Reimu held out. And as Yukari let out a soft burp to bring an end to her binge, she quietly yawned. "You really are remarkable, Reimu. If this had been your Mother, this would've been a much different story. But I suppose I'll let you off the hook for now." She said, as she pushed her plate into another gap. All while finally getting off the Shrine Maiden's lap.

"But if you ever feel like you need more... If you ever feel like you need to indulge and cut loose. You know how to get ahold of me." Yukari whispered into Reimu's ear, right as she kissed her on the cheek. And walking into the Shrine, because she wasn't going to leave her alone at all. No, she was going to just take a small nap. And see if she could convince Reimu to have another go at her body after that.

Once Yukari had left, once she was sure that she was all alone, that was when Reimu finally drew breath once more, sweat running down her face. She could feel the arousal pounding through her. She could feel Yukari's teasing taking effect. And she... She...

She needed a bath. She needed to get completely scrubbed clean. Cleansed in the holiest spring water, all so she could get free from this.

"You're redder than Lady Remilia's favorite dish, darling."

Reimu's eyes widened as she heard a soft voice speaking. But she tried to compose herself. Right as she turned towards a tiny maid standing at her side. A maid whose bosom was currently covering up most of Reimu's vision.

"Sakuya. Are you not tired of that act? We're not married. Furthermore, why are you like this?"

Izayoi Sakuya. Remilia Scarlet's Head Maid, and one of the few Humans that could fight against Youkai on a regular basis. And a girl that truly didn't think on the same wavelength as many of the other people in Gensokyo. Whether Human or Youkai, it was hard to truly understand what she was thinking. Because neither were truly capable of grasping just how she understood things.

This was all the more evident by what she had done once she received her latest order from Remilia. 'Go to Reimu, and make sure that she understands how thankful I am for her help.' Was something that should've been rather reasonable. It was a show of gratitude that she had to carry to Reimu. And yet...

Sakuya understood what Remilia wanted. But her understanding was more regarding the spirit of the want. And if she wanted Reimu to feel grateful for that gratitude, then she had to make sure that she treated her accordingly. What were humans truly fond of and grateful for? Their kin. Their spouses. And since Sakuya knew that Reimu wasn't ready to be a Mother, she went with the spouse route.

Combine that with the fact that it was obvious that Reimu was into younger individuals, and into fatter forms, she went ahead and used her power. From there, it was easy for Sakuya to turn back the biological clock... And at the same time accelerate the process of gaining pounds. Which was why she was able to have such large melons despite being about the same size as Suika and Yukari.

Not that the bosom was the only thing that stood out about Sakuya's youthful form. That maid outfit, which had been properly adjusted thanks to a bit of magic from the Scarlet Devil's Librarian, was struggling to truly contain her gut. A gut that wasn't nearly as big as Yukari's or Suika's, but one that served as support for her bosom. Lifting up the rest of her flabby body, and making it look that much more impressive.

"Act?" Sakuya asked, as she took a seat by Reimu's side. Leaning against her, just as a spouse would towards their partner. "Why would I put on an act? I'm doing what my heart tells me, darling. And since you look so troubled, perhaps I should stay here and make sure you recover." She didn't see anything wrong with treating Reimu as a spouse. Nor did she see anything wrong with being this close to her. Despite knowing that Reimu did her best to resist temptation.

Reimu could feel the sweat running down her face as she stared towards Sakuya. She could feel it all bubbling around inside. If she did anything to Sakuya, then... Not only would she be breaking her vows, not only would she be indulging... She would also risk potentially pissing off Remilia. Which could lead to another incident in and of itself... Or worse, the Scarlet Devil altering fate to ensure that she would suffer further for her transgressions. Probably by making it everyone else's fate to grow bigger, just to make it impossible for Reimu to ever do anything ever again.

Admittedly, there was once a time where she wasn't into all of this. But it all just started to snowball. Reimu originally thought that these fat bodies were disgusting. That they all had fallen for some sort of wicked trick. It was the best way to explain why they had grown so fat. And yet she treated them nicer. And yet she endured. She could've stopped them at any point. And slowly, their misconceptions, and the way that they tried to tease her... It became more and more effective.

Now she sat here. With her 'spouse' at her side. With Yukari currently trying to catch a few minutes of sleep inside the shrine. And with Suika currently digging through the storehouse, probably trying to find the sake that she craved. If she were to break her vow... Now would be the best time. Not only that, but it would be with the best possible partner, considering Sakuya's tendencies. Even if she was weird, and thought on a completely different level compared to anybody else she had met...

Reimu felt her heart trembling as she reached towards Sakuya. She reached towards those fat breasts... Past them, down towards the firm belly that was hiding underneath. One... One touch wouldn't hurt. Just one. Just one teeny tiny touch...

Sakuya, of course, didn't try to stop her. She just looked at Reimu with a smile. If her spouse wanted to manhandle her belly, then that was just what she was going to do. Otherwise, she wouldn't be representing Remilia's gratitude properly. She had to make sure that she represented that gratitude properly. Otherwise, she would be making Remilia quite sad.

Just as Reimu was about to bury her fingers in that belly. Just as she was about to break down and actively try to have fun with the kink she tried to keep burying. She heard the sound of laughter, and the sound of something breaking. She had an out. Finally. She could breathe easy..!

"Suika! What did I tell you!?" Finally, she could raise her voice. Because property damage was beyond the bounds where she had to restrain herself. Now she could properly chew out the Oni for causing trouble. And get away from Sakuya, even if only for a moment.

Suika giggled as she slowly wandered over to the shrine with a few bottles of Sake in hand. "Soooorrrryyyyy. The door just didn't wanna open. Did ya jam it shut or somethin'?" She asked, before idly giggling again. She was still far too drunk. And she wasn't getting any more sober any time soon. "Sooo... How about a drink?"

Reimu pulled out her Gohei, and bonked the drunk Oni on the head. "Be glad I'm not exorcizing you for that stunt." She said. Even if she knew it wasn't a proper punishment. She still couldn't bring herself to make her pay further. It wouldn't be right. She was too cute, too plump for that...

"Ehehehe... Thaaaaanks. And sooooorrry, Reimuuuuu." Suika chimed as she grabbed ahold of Reimu's tummy as thanks, before planting a big ol' kiss on it. She would do more, but she was far too drunk to. Which was a blessing in disguise...

Especially since Reimu's tummy just so happened to get extra loud and grumbly in response to the kiss. A grumbly sound that brought eyes on her. Not just from Sakuya, who was still sitting on the steps leading into the Shrine... But from a gap that opened right by her tummy, with Yukari's devious grin barely hidden within as well.

"My my. You're sounding awfully hungry, Reimu. Don't worry, there's still some meat left. If you really want to fill that tummy of yours, I can lend you my lap for a bit. Then that maid can feed you like the spouse she thinks she is." Yukari chimed, all while she actually walked out of the Shrine. Teasing her remotely, while getting nice and cozy by Sakuya.

Sakuya's eyes lit up in response to her duty being respected, as she quickly headed inside. It was easy to hear the floorboards screaming in agony from the weight of the hefty girl running along. And before long, the sound of food being made inside the Shrine began to echo out.

There was nothing that Reimu could really do now. What she believed would be her salvation was actually trapping her more permanently. And thus, she finally gave up. And she lumbered over to the steps, all so she could lay down and close her eyes, hunger pangs echoing out around her.

The Shrine Maiden of Paradise was a difficult title to hold. And so was the title of Hakurei Shrine Maiden. At the end of the day, Reimu was only human. And as she laid her head down on Yukari's fat thighs, as she rested on that young lap with the endlessly old yet adorably youthful Sage looking down at her, and with the smell of her 'spouse's cooking reaching her nostrils...

She began to drool a little. And she closed her eyes, hands drifting onto her own belly. Fine. She gave up. She'd indulge. But tomorrow... Tomorrow was going to be different. So to make sure that she wouldn't be tempted tomorrow...

Reimu would stuff herself until it felt like she'd burst. Repeating this cycle over and over again, as she had done for about a month now. The true cause of her and the girls' gains, which she just couldn't avoid no matter how many times she tried.

All capped off by her hungry stomach growling. As it had done so many times, and as it would continue to do as they kept on growing fatter and fatter.
