“Raikou, Musashi, Ishtar, you’ve all been working so hard lately that I think you could all use a well-earned break. Therefore, I’ve booked you three in at an island resort getaway, where you won’t have to think about anything but relaxing. That’s what Ritsuka said, right? Ain’t they just the nicest master in the world?”

Miyamoto Musashi, master swordswoman, recited in response to the fretting of her companion, crossing her arms and leaning on her shoulder.



“Yes, I do believe so.” Minamoto-no-Raikou, the tall, leggy Japanese beauty said, her hips naturally cocked out to one side as she gazed out over the side of the boat to where their island paradise awaited them.. “But still, I just can’t help but worry about leaving them alone for so long.”

“In my opinion,” The goddess Ishtar stated, currently inhabiting the body of Rin Tohsaka, “It would be most disobedient of you to continue worrying this way and that about Master after they’ve specifically commanded you to relax. I, as the exemplary servant I am, shall be sure to do so.”



“Ishtar’s got it right!” Musashi enthusiastically declared. “You ain’t supposed to think about anything but eating, sleeping, and drinking for the next two months! There’s that western saying, don’t look a gift horse in the mouth, ain’t there?”



“I suppose so.” Raikou took a deep breath, dispelling her woes.

“Then I don’t wanna hear a negative word out of you until we step back onto this boat.” Musashi said, and that was that. She loved fighting, but she knew when to kick back every now and then, and was eager to try out this “resort” thing she’d been hearing so much about.

 The three female servants stepped off the boat not soon after, where their island paradise awaited. The small island was as picturesque as it got, with crystal-clear blue water and gentle waves around soft sand that stretched around the island, giving way to palm trees and a path that led from the pier into a Japanese-style inn where they would be staying. Although nature was on display now, if you walked around the island you’d find other boats and things to do, and at the centre of the island was a shopping complex for those who wanted to enjoy life’s simpler indulgences.

“Alright, so,” Musashi said a few hours later, having arrived, checked in, and then explored the island and discovered all of the above. There were even other things to do, like an onsen that they planned to soak in at some point. “I think we’ve scoped this place out. What’re we gonna do first? I know what we’re gonna do for the next couple of weeks, but we’ve got the rest of the day free.”

“According to Ritsuka, this island is famous for their food.” Ishtar said, holding a brochure that had been given to them at the front desk that boasted the same.. “And I’m quite famished after all this walking around, not to mention the ride here.”

“I was gonna go check out the beaches, maybe take a load off, but that sounds good to me too!” Musashi siad, shrugging her shoulders.

“I’m quite content to do whatever you ladies would prefer to do first.” Raikou said with a motherly smile, as if she was escorting the girls on their trip. “But perhaps we should get changed into something more suitable…”



“Speak for yourself.” Ishtar said smugly, her casual outfit more suited as beachwear than perhaps even her beachwear.



“I can’t be bothered, let’s eat now!” Musashi declared, and the three decided that food was the first order of business. They had more than enough time for everything else, after all. But soon they’d discover that food might end up overriding all other priorities during this trip…

–

“Is it just me or is this place really good?” Musashi said, the rose-haired girl having wolfed down her seafood meal within minutes of its arrival. She put her chopsticks down and called down the hall at the employees. “We’ll have seconds!”



“It’s quite sublime, isn’t it?” Raikou said, humming appreciatively as she savoured her meal at a slightly slower pace. Supposedly the ingredients were unique to the local ecosystem and were prepared with a unique traditional island method, although Ishtar had brushed it off as marketing fluff prior to getting it in her mouth for the first time, at which point she quickly changed her tune.

“Finally, something that lives up to its reputation.” Ishtar made a passing gesture at elegance, but had finished her food just as quickly as Musashi. “I can’t remember the last time I had something this good.

“They do breakfast too. Guess we’ll be eating here for most of the trip!” Musashi laughed, feeling like her stomach was bottomless as the second course arrived. The two would finish a third and fourth before their stomachs were finally full, not realising how gluttonous they had been until it was over. Still, it was just one meal, they all collectively agreed. It wasn’t like a little overeating one time would make them fat or anything…

–

“I think I could really get used to this.” Ishtar sighed, sunbathing near the pool in her white one-piece swimsuit.

“Likewise.” Raikou agreed, lounging beneath a parasol in her usual daringly skimpy bikini. Of course, Musashi was so slouch, paddling over and leaning over the side of the pool, planting her bikini-clad breasts on the wet pavement as a chin-rest.

“You guys should swim too! You’re missing out!” She said.

“Can’t be bothered.” Ishtar sleepily replied, closing her eyes and continuing to work on her tan. Raikou considered doing the same, then pulled herself to her feet.

“I suppose I might take a dip as well.” She said, and as she brought herself upright, Musashi couldn’t help but feel that she looked just a little different. Her almost impossibly slim waist didn’t look quite so impossible anymore, almost rather normal now, her hips a little wider and her bikini looking a bit snug. But it was probably just her imagination, Musashi thought as she climbed into the water.



Meanwhile Raikou looked at Musashi, and couldn’t shake the feeling that Musashi’s boobs looked a bit bigger than usual, that the straps were digging into her flesh a little, particularly her bikini bottom with its tight strings. But that couldn’t be right, as it would have meant that they’d gained weight in a mere week since arriving, and no matter how good the food was, that couldn’t be the case. Ishtar’s thighs too were probably just a little thicker than she remembered…

–

“Fancy meeting you here.” Musashi said cheerfully as the three coincidentally ran into each other at an island crossroads. Ishtar had come from the inn, Raikou from the pool, and Musashi from the beach. Each was clad in their swimsuits, having taken to wearing beachwear around the clock rather than bother changing in and out of their regular clothes

“Perfect timing.” Ishtar decided. “I was just about to go shopping, and I could use some accompaniment.”



“How convenient, so was I.” Raikou commented.

“Geez, you too?” Musashi laughed. “I don’t suppose you’re having the same problem I am, are you?”



Musashi tugged at the corner of her bikini, the starry triangles looking like they were holding on for dear life,and covering precious little of her considerably larger boobs. Her belly beneath them was looking rather soft to the touch, almost a bit chubby, but her breasts easily distracted one from noticing.

“I must’ve bought the wrong size or something. Need something bigger to let the girls breathe.” Musashi said, although it was clear that the bottom half of her bikini was rather strained too, her big butt starting to swallow the fabric.

“Mine are feeling a bit tight too.” Raikou noted, hers in a particularly strained state. Her waist was really starting to fill out, her hourglass curve slowly but surely starting to vanish as she gained the beginnings of a pot belly. Her breasts and butt had increased in size, but only modestly by comparison.

“Perhaps these all shrunk in the wash together.” Ishtar suggested optimistically. Her jacket concealed her own chubby belly, but her thighs were looking particularly juicy and her ass crack had swallowed her inadequately sized swimsuit whole.

Of course, none of the girls said anything about why this might be the case, nor commented on their observations about each others’ figures. To do so would admit that they themselves appeared to have grown in places, and that was impossible. After all, they’d only been here for two weeks! The distinctly chubby group avoided the topic entirely as they headed off to the shopping mall.

“We should pick up something to eat while we’re there.” Raikou suggested, the other two agreeing enthusiastically…

–

“No more!” Ishtar groaned, clutching her distended belly with a pile of empty plates in front of her. “I can’t eat another bite!”

The goddess Ishtar looked like a stuffed pig, thanks to almost four weeks of over-indulgence and her hips overflowing her seat.

“Aw, but I wanted to try out that Korean barbeque place next!” Musashi complained, her own pot belly hanging out proudly.. “You’re such a lightweight, Ishtar!”

“And I was going to suggest we get Mexican again afterwards…” Raikou said, a greedy expression on her face. She too had an overstuffed gut, one that was noticeably larger than the other two.

“You know,” Ishtar started, looking weary of her friends’ enthusiasm. “You two are really starting to look like a couple of…”



Ishtar stopped, clutching her own taut yet soft and padded gut, suddenly well aware of how her chunky thighs were rubbing together. She was going to say that her companions were starting to look like their eating habits were catching up with them, with how Raikou’s waist had completely filled out until she was more of a pillar than an hourglass, and how Musashi’s boobs were seriously starting to grow out of control with how she was on her third bikini already, but to do so would invite comparison to herself, and she pulled herself back from igniting the powder keg.

“Never mind. “ She said with a pout. “And on second thoughts, maybe I can fit in a little more…”

–

“Nothing like a good soak to finish the day, huh?” Musashi said, stepping into the inn’s onsen and watching the water overflow slightly as the three added their weight to the pool of water.

Ishtar was already in and looking like she was in heaven, taking a load off her tired feet. She took up as much space as her and Raikou side-by-side when they arrived, her hips well and truly bloated, to say nothing of her bloated belly that was pushed out as far as when it had been stuffed a week and a half earlier, piling on pounds in rapid succession. Now it had been almost a month since they arrived, and the girls had gone beyond chubby and plump well into undeniably fat.

Although Raikou has been the thinnest when they arrived, albeit simultaneously the most stacked, that figure had been long since left behind. She was distinctly apple-shaped now, with a big round belly that outpaced the growth of her boobs or butt, her chest outpaced by Musashi, although still dwarfing the unfortunately bottom-heavy Ishtar. Bigger than her head was no longer simply figurative, and each one floated on the water as she sunk in down to chest height, her puffy face joining Ishtar’s in mutual bliss.

Musashi was the most top-heavy of the three, with breasts that were approaching the size of the cantaloupe melons that she had had for breakfast this morning. While her hips and thighs were naturally nothing to sneeze at, her belly was by far the smallest of the three, sagging out but lacking the spherical shape of the others, and highly overshadowed by her chest.

“By the way…” Raikou said, feeling the weight of her gut even with it lightened by the hot water. “I couldn’t help but notice…”



“Get on with it already.” Musashi prompted her with a yawn, feeling just about ready to nod off if she didn’t hurry.

“Yes, my apologies.” Raikou chuckled slightly. “I was just thinking that we seem to have put on quite a bit of weight lately.”



“You don’t say.” Ishtar said sleepily, the hot water dulling her indignation. “



“Now that you mention it…” Musashi said. “I was really feeling like I couldn’t see my feet lately. Guess you’re right.”

“What are we gonna do? We’re going to be so fat by the time our trip is over.” Ishtar mumbled, sinking down until her words turned bubbly. She’d been aware of her own weight gain, but had been waiting for somebody else to break the ice and had told herself that the three of them hadn’t gained that much. Now the the denial period was over, it was impossible to see the three of them as anything but a bunch of over-indulgent fatties. However, Raikou had other ideas.

“I think it looks rather good on us.” Raikou commented, pinching her engorged waist. “Perhaps a little extra padding was what we were missing.

“Seriously?” Ishtar pushed herself up a little. “No offence, but you look like a total fatass right now.”

“Of course!” Raikou said more enthusiastically. “Why, it looks rather splendid on you in particular, lady Ishtar.”

“Yeah, a little meat on the bones ain’t a bad thing.” Musashi chimed in. “All the guys ‘n gals on the island have been giving you real jealous looks.”



“R-really?” Ishtar, weak to flattery as always, immediately. “Well, of course it does. This type of figure was highly prized in my time, you know. It stands to reason that it would come back into style. All trends come in cycles, as they say!”

Ishtar, either due to mental weakness or perhaps mental resilience, had already stopped minding her own weight. After all, deciding that it was a good thing allowed her to avoid responsibility for it, and indulge even harder.

“We’re on vacation, right? We can afford to let ourselves go a little.” Musashi reasoned. She’d never been fat before, and found it an interesting and novel experience, particularly with her confidence in burning it off. “No reason why we can’t just lose it at the end, seeing as we gained it so quickly. It’ll be a piece of cake!”

“Yes, I’m sure.” Raikou said, already drooling at the idea of a little post-soak cake before bed. The biggest glutton of the three, she was more than certain that her master would forgive her figure slipping a little. “Although we do seem to have put it on unusually quickly. We’ve been eating quite a lot, but not so much to earn all this.”



Raikou squeezed her flab for emphasis, finding more than enough to make her point. She was already finding it rather suspicious that their master had picked this island in particular to send them to…

“Must be that secret recipe stuff’s dark secret.” Ishtar guessed. “No wonder everything on this damned island is so tasty. Maybe I would have taken more care if I’d known in advance…”

“Not like you’re gonna eat any less of it from now on.” Musashi laughed, Ishtar.shrugging.

“At least it isn’t all going to my chest like those udders of yours.” Ishtar jabbed, Musashi merely groping her own breasts to boast of their size, knowing that Ishtar would need to get twice as heavy just to catch up.

With the situation defused by their surprising acceptance, helped along by how it was impossible to get upset in such comfortable waters, the three officially agreed to procrastinate on properly addressing the issue, and with that, they were locked into even more over-indulgence on their trip…

–

“What do you think of this one?” Ishtar asked, stepping out of the changing booth wearing tight yoga pants that she had somehow managed to squeeze herself into, and a sleeveless top that just couldn’t contain her pooching belly.

“I think you look splendid in everything you try.” Raikou said, herself clad in a simple white sundress that normally would have been quite loose but was now clinging tight around her ample gut.

“I appreciate it, but I need an actual opinion!” Ishtar said, even her appetite for flattery, even bigger than her normal appetite, was tested by Raikou’s unjudging kindness. Raikou’s motherly aura had been enhanced by her roundness, and she always had something nice to say about her companions. Unfortunately, this made it a pain to extract anything other than easy approval from her, such as when she wanted to know which was the best outfit out of the ones she had picked out.

“Forget it, I’ll just get everything.” Ishtar said, throwing in duplicates in the next size up for good measure. It was a good idea, taking into account her impending weight gain, but she would soon discover that by the time she remembered them and tried them on, she would have already outgrown those as well.

“I think I’ll keep it simple.” Musashi said, coming out of her booth wearing a pair of denim short-shorts (unbuttoned and unzipped for comfort) and a cleavage-bearing t-shirt that was tied under her breasts, not that it could have hoped to cover her midsection in the first place. It gave a certain cowgirl sort of look to the Japanese woman that contrasted her normal kimono, and added a touch of playfulness.

There was one conspicuous similarity between the three beyond their decision to try skimpier clothes: save for their intentionally loose dresses, each and every one left their bellies uncovered via tank tops, crop tops, and boob tubes, leaving it plenty of room to grow when they eventually stuffed themselves so thoroughly their pooching bellies stood taut and round, pushed to their limit by the unrestrained gluttony the women had fallen into.

“Now,” Musashi said after the three walked out with shopping bags in hand. “Let’s get these back to the inn, then get these off and hit the beach!”

“I’d like to get a snack first.” Raikou requested, her stomach growling even though they had all eaten less than an hour before…

–

“What do you want to do now?” Musashi asked the other two on the sixth week of their trip. The three were leaving the beach, where they’d intended to spend some time playing in the water, but had all ended up lethargically sunbathing, pinned down by their own weight and too lazy to get back up. Certified fatasses, their weights were increasing exponentially as the trip reached its last quarter,

“Let’s go to the all-you-can-eat buffet!” Ishtar said shamelessly eagerly, already starting to drool at the thought. It was becoming the three's most frequented place, and today would be no exception.

No longer did Ishtar complain about hitting her limits, taking to her gorging enthusiastically until her stomach capacity increased day by day, and with it her waistline expanding by inch after inch.  Yet no matter how much she ate, her stomach still paled to Raikou's, the majority of her fat going to her breasts and belly.

Eventually, mere stuffing sessions spread around multiple restaurants weren’t enough for the women. While each had their own individual tastes and preferences, their gluttony overrode even the slightest of individualism in the face of their overwhelming desire to simply get as much of the island’s delicious food within them as quickly as possible. It didn’t matter what it was, whether it was meat, grilled vegetables, seafood, or sweets, as long as it was within arm’s reach and crammed into their mouths as quickly as possible.

Losing all vestiges of restraint, it was no wonder that with only a little over two weeks to go, the women had ballooned. Ishtar was having to start worrying about getting stuck in doorways, with how each thigh was so chunky that it required considerable effort just to lift them in order to waddle around the island. Her face was often in a daze, the smug goddess now having more in common with a fertility goddess with how she thought only of sating her appetite before lounging in the sun to give her time to digest before her next gorging session.

Musashi, one of the most gifted swordswomen in the world, had paid little heed to what quadrupling her weight might do to her sword skills, and it was now extremely doubtful that she could wield a weapon with any type of grace, let alone masterful duelling abilities. She looked like she might wind herself just swinging one, if her gigantic udders even let her hold it properly. She’d nearly knocked herself out during an attempted game of beach volleyball, retaining enough strength to hop off the ground which sent her pillows flying directly into her face, blinding her and causing the distinctly unathletic Ishtar to score a point over her. Her bikini had cups so large that one’s jaw might drop at the size of them, and yet she had outgrown it so quickly that the extra-thick string was holding on for dear life, the triangles doing just enough to keep her modest and providing precious little in the way of support as her once perky breasts sagged under gravity and their own immense weight down to cover the comparatively small but quite flabby gut that hung underneath. Perhaps she would overcome the trial of being several hundred kilograms overweight and display remarkable deadliness in the end, but right now she looked about as dangerous as a katana made of foam, and thrice as soft.

It was hard to believe that Raikou had once had such a lanky frame, with her bean-bag gut and melons that rested happily on them. For a while it had been unclear whether her boobs or belly would come out on top in size, and in the end the two seemed to come to a happy truce, where her barrel-like stomach would serve as a perch that served to make her chest seem even larger. Raikou didn’t mind in the slightest, considering herself to be extra cuddly and enjoying the stark contrast her jiggly body had with her slim frame she’d possessed for so long. When she thought about the hugs she might give her master, it made her eager to get even bigger, her greedy smile widening at the thought. It was difficult to believe that just a few weeks earlier, all three had been beautifully slim women, and not a chubby chaser’s dream trio…

–

“Have you got it on yet, Ish?” Musashi asked, her footsteps heavy on the tatami mats of their room as she settled into her bikini. But not just any bikini, or one of the many that she’d brought to keep up with her prize melon sized breasts, but the very first bikini she’d brought with her, the one that she’d thought would be more than enough for the entire trip.

The three had decided to put on their old swimsuits just for fun, which had turned out to be easier said than done, particularly for Ishtar, who had brought a one-piece rather than the bikinis the others took.

“I’ve almost… got it…!” Ishtar pulled up her one-piece swimsuit with the help of Raikou, who had her sausage-like fingers hooked under the top straps as she forced it onto the top of Ishtar’s puffy shoulders. The three’s arms were so filled with fat that each looked like they had no hope of holding weapons, piled onto biceps that resembled flabby wings, squashing and stretching in a way that made the mere act of putting on their swimsuits cumbersome.

“Just a little more!” Ishtar begged, gasping and red in the face as she just barely managed to squeeze into it, owing to how most of her fat was concentrated in her undercovered hips and thighs. Raikou let go, the straps falling with a meaty slap into her soft shoulders, every inch of her body thick enough that you could sink your fingers into it. Her gut stuck out enough that she had to reach to wrap her arms around it, but at least it wasn’t as bad as Raikou, who she was starting to doubt could reach her navel without significant effort.

“See? Nothing to it.” Musashi slapped her on the back, Ishtar almost yelping as she felt like the impact would cause her to wobble so much that her swimsuit would explode off her body. Yet even though she had the most skin to cover, Raikou and Musashi were probably in more trouble than her. You couldn’t even see the lower half of Raikou’s bikini, and in both cases their breasts were so huge that the woefully inadequate patches of fabric barely covered their nipples, the strings digging into the skin around them. Each’s chest wobbled and bounced like the bikinis weren’t there at all, and it was clear that their swimsuits' days were numbered.

“Whose stupid idea was this?” Ishtar muttered, ignoring the fact that it had been her idea to challenge the others to see who could still fit into their original swimsuit to “prove that they hadn’t gotten that fat”, even though each one was pushing at least four hundred pounds. Every single day they remained they got visibly larger, even without how big they already were.

“Hey, want to go to the beach like this?” Musashi snickered. “We got ‘em on, so I’m sure they’ll be fine!”



“Are you crazy!?” Ishtar had enough self-awareness to exclaim. The two would argue back and forth about it, but ultimately the matter would be settled by all three’s swimsuits tearing at the same time before they could get out the door…

–

“This was a wonderful trip, don’t you think?” Raikou said, the three relaxing in the onsen the day before they were due to leave.

“Such a shame we can’t stay longer.” Ishtar sighed, at the apex of her growth. She had to enter most doorways sideways to avoid getting jammed, and her hips took up enough space for three women around her. Immensely obese, all three were so fat that it was unclear who was the heaviest, all bulging out in their own unique ways. Despite the fact that just moving her legs exhausted her, Ishtar arguably had the easiest time moving around, thanks to Raikou turning into a ball of blubber and Musashi having two beach ball-sized mounds of flesh hanging from her chest at all times. Ishtar’s, merely as big as her head, looked positively puny compared to the others, although her gut was an impressive feature of its own.

“I don’t think I’d be able to leave if we stayed much longer.” Musashi admitted, both figuratively, and also in that even she was starting to struggle to stand up once she had sat down. “I don’t know how I’m gonna even begin to burn all of this off. I wonder how master is gonna react when we get back. Do you think they’ll put us on a diet the moment they see us?”

“I don’t wanna diet! I don’t wanna go on a diet!” Ishtar suddenly moaned, her head in her hands as her bulk caused waves in the hot spring. “You can’t make me! I don’t care if I stay fat forever!”

“I personally am not in any particular hurry.” Raikou smiled, her belly so big that it poked out of the water even when she was almost completely laid back. “I have reason to suspect that our master prefers, shall we say, larger women such as ourselves.”

“Well, I guess that’s obvious.” Musashi commented, dipping her breasts deeper into the water, the only time she could be relieved of their weight. “Bet this was all part of their plan to begin with. I wonder if we got even bigger than they intended.”

The three collectively sighed, sinking as far as they could into the onsen. They hoped that when they got off that boat, their master enjoyed the first sight of his trio of tremendously obese servants…
