Work Text:
The Nine Fox Foundation worked tirelessly even without its beastly CEO sucked into the Grail for her own purposes. Offering her services to the Chaldea Security Organization after having her true intentions revealed hadn’t dampened too much of her influence, especially not when she’d been explicitly summoned by Chaldea’s one and only Master herself.
Of course, her connections didn’t stay severed in the slightest with everything coming to her one way or another. Tamamo Heavy Industries, the premier weapons manufacturer in the world, was still subject to her explosive whims with no doubt countless armaments left off the table once that faux Vitch disapproved of its less impressive spectacle for the end of world.
Not one to dabble in the realm of biological weaponry, it was only natural that advancements in such fields then festered in obscurity. One such treat, a reactant ready to make any man or beast into whatever they ate was one such forgotten concoction that eventually sprung a leak to the room below its storage. As it just so happened to be the confectionary branch of the NFF, tainting a whole, creamy batch was only natural with an expectation of reaching the one and only Koyanskaya herself.
In her comparative squalor, Koyan enjoyed the fruits of her vile labors on the other side of things. A frequent consumer of her own product as any in her position would be, another case of her Pink Bunny branded ice cream arrived as it always did per month for her own comfort.
Ripping open the box, she put up its contents with one hand to eat herself just as her Master interrupted her, “Hey Koyan! Whatcha doing !?”
A very skinship heavy girl, Ritsuka Fujimaru was a perverted thing beyond compare when it came to her beautiful selection of Servants. With Koyan as a treasured favorite, it was only natural that she barged into her room whenever she wanted, “Oh wow! Is that ice cream!?” The girl had the world on her shoulders yet confidently strode in with an airheaded glee just to be alive and able to assault pretty girls.
“Y-Yes… Very premium and fairly priced at a year’s worth of your wages, this is a new collection of flavors straight from NFF that I was hoping to sample, but if you insist, Master, then I suppose I’ll have to let you have a bite,” Ritsuka rushed the fox with shining eyes and outstretched, unwashed hands grabbing at the delicate package, “ If , and only if , you’re able to pay for it. I can’t operate so easily on handouts, so I’ll let you have a discount at the very least~”
From her black jumpsuit, Koyan produced a card reader and smugly flicked her bushy tail upon seeing her Master’s face lose all its color, “Oh well… It could very well be poisoned, so I’m protecting your life as a bodyguard like this anyways~” She ripped open the flimsy packaging and stuffed the whole thing in her mouth. In the short moment between gulping it down, it was seen to be a small, neapolitan tricolor block of ice cream without any good way to eat it as expected of a beast willing to get her fingers sticky for a little misery.
Ritsuka was sad to see it disappear like that, but with a soft serve machine in the cafeteria, she could tap the stuff straight into her mouth when Archer wasn’t looking and rekindle her spirits in an instant, “Well, I guess that kinda sucks, but it doesn’t really matter…” Koyan’s joy similarly drained as her Master’s once did, “Oh, does that face mean I can have some now , though? They only have vanilla in the cafeteria!”
“N-No! You cannot have our Pink Bunny brand ice cream with pre-orders open on our website for only 10% more than in stores!” Talking her way through an ad didn’t phase her simple-minded Master as her eyes travelled where they usually did once the conversation was over, “And why aren’t you paying to look at my body with lecherous eyes of yours!? I thought it was agreed that-”
“Yeah but your belly’s getting bigger, so it’s different this time!” Ritsuka pointed to the fox’s stomach as it clearly bulged a bit under her tight jumpsuit, “That’s weird so I can look at it for free even if it’s hot!”
Koyan dropped nickel and diming from her schedule to pay attention to her belly developing a cute paunch before growing even more, “Just what did they give me…” It was a slow growth at first with excusable portions of chub puffing up her stomach and only that as the ice cream inside exponentially multiplied itself.
With her hips unzipped and exposed, there were inklings of pudge poking and up and the sides. From a pert bit of tummy was a full on potbelly developing right in front of her. A genuine pregnancy of sugar and cream was going from month to month in seconds without any semblance of stopping.
It was as her Master said and more with the slightest bit of indulgence turning into an infinite supply then churning around her insides. Just a smidge of bloat welling up in her stomach was turning into an everlong pressure bubbling up into a loud, “ BWUWUwuUpAuAUrpuARUP …”
“Woah! That’s almost like whenever I suck it straight from the source!” Ritsuka patted her stomach through her top, “Last time gave me a little tummy, but that’s crazy!” She transitioned to pointing at the fox’s beach ball middle coming to term with a milk-based set of twins then budding into triplets and beyond, “You’re fat! Fat fox!”
“W-Watch your mouth!” Koyan was reeling from her embarrassing belch with another well on its way if she didn’t keep it choked down, “This isn’t- oRup -right… This can’t be happening to me!” A fully spherical tummy hung off of her like some ridiculous soccer team’s worth of children fighting in her womb with the only loser being the one forced to bear it all.
Koyan tenuously touched her huge stomach, “oguh It’s s-so sensitive…” Her form-fitting bodysuit was nothing against the tide of her inflation near popping the zipper off the front. No bare belly, it pained her even more, “uouggh It hurts…” The thing lightly wobbled with the motion of its sugary ocean inside.
Groaning as it sagged down over her crotch, the fox was too focused on getting out of her situation to notice it getting any worse as once again pointed out by her perverted Master, “Butt! Butt fox! Your fox butt is swelling, too!”
“You c-can’t be…” Koyan’s hands shot to be pert backside just to just the lumps of wrath plumping up just as her stomach, “How is this possible!?” Just as the rest of her seemed subject to an ice cream filling more akin to obesity than fluidity, her stomach followed suit with a softer shape of actual flab quickly digesting into a fat stomach leaving cream for her curves.
With only one somewhat chubby Servant at disposal, Ritsuka was enraptured by that Russian treat plumping up into a fine dessert, “You look so soft, Koyan! I bet if I touched your belly like this, I’d just fall in!” Ritsuka pushed her luck with the world’s future destroyer with an outstretched plunge sinking her open-palmed hand into that gut.
Expecting the soft embrace of a fluffy beast through hibernation, Ritsuka was met with a strange winter chill radiating off of Koyan’s Siberian belly. Still, the creamy texture of womanly excess was flush in her hand and stuffed with even more dairy than the girl ever expected, “Wow you’re cold like snow or something! Are you snow or something!? Or no… That’s cooler than cool! Ice cold!” The Master was content to sink her fingers into that flourishing obesity even if squishing the flab was cooling her to the bone.
“Quit that! Act like a normal person and stop treating me like some window-shopped junk you can just- hrkk ” Koyan reflexively grabbed her billowing mattress in the making before slapping her Master away, “You’ve made me sick…” Her tail drooped to the floor for effect.
Blaming her Master for anything was the least she could do to save face when it was clear that whatever was happening to her had to be her very own fault. Suddenly fattening up all around, each one of her buttcheeks rounding to a weighty bowling ball each of flesh and more, it was obviously the product of some failed project she’d chosen to forget about. As such, it was only natural that Ritsuka came off then with a hand slicked and sticky with what only should’ve been inside.
That cloudy, off-white glaze coated the girl’s fingers didn’t go unnoticed, “What is this stuff!? My hand got all gross and sticky from touching your fox tummy! What’s up with that!?” Without thinking, she foolishly popped her thumb in her mouth, “ mhm It’s sweet! Like… Like ice cream!”
“That’s ridic- hehrgh ogughh … R-Ridiculous…” The fox tried to keep a brave face and push through the wobbly flood of something more than fat getting jiggly in her legs, “It’s only some extra weight… That’s all…” Pale as an arctic fox under all that pink and black, Koyan’s ghostly complexion was being supplanted along with her figure to be a nice, almost yellow pallor somehow more sickly than the real thing.
Blobby thighs were sausage squeezing of her hip windows along with the hips themselves widening out to delightful double then triple width meant to keep her away from doors especially made for her. Of course, such things only mattered for the actual overweight instead of the product in the making with little black specks dotting her smooth, bloated curves like misplaced freckles. Yes, as the colors shifted, she became all the more vanilla bean over vulpine.
In a mismatched pear shape, Koyan was smart enough to quickly tear her boots off before she’d have to pop them off like sausage casings, “ hhgrgn … I can’t be… Ice cream’s just so… It couldn’t have been something more…” Her cunning kept her moving from one thought to next knowing there was no way to stop her transformation let alone contact NFF before she’d be a calorie-heavy blob barely worth her weight in the milk, sugar, and cream she’d be made of.
Ritsuka was taking it all much better, “Wow, my own ice cream girl! We’ll have to put you in the big freezer and make sure you don’t melt and keeping feeding you cream so you can get even bigger and we can have infinite-”
“You already have unlimited supplies you idiot! And what makes you think I’ll be staying like this!?” Koyan motioned down her half-transformed body with yet only one flavor to choose from, “A freezer, however, is an important provision to secure early on, I must say…”
Being right in any way didn’t matter as long as she had her girls, so Ritsuka reached out from another taste before getting slapped away for being a gluttonous child, “You can’t eat me, either!”
Ritsuka slinked away only temporarily while Koyan went right back to being reconfigured into the walking dessert she was destined to be. A belly full of, and then made of, a hundred or two pounds of sugary slop had only been impressive when seen without the whole picture well enough forming before the duo’s eyes. Tirestack legs of perishable material melted down from the fox’s bulbous, bench-made ass into hardly consistent and squishy pillars at odds with her feet at the end.
Streams of warmed vanilla streaked down the surface and seeped out the zippers while prepping a push up against gravity. Her body could only be a temple, small at the top and wide at the bottom, for so long without filling out the upper levels with sweet slurry.
At the same time, the frantic swishing of her fox tail seemed to flick pieces of itself off all of the sudden, “You’re throwing pink everywhere! That’s your fox essence, you gotta be careful or else you won’t be a Tamamo anymore!” Rituska pointed to the pastel splats on the wall and ceiling.
“That’s not how the tails…” Faking her way into the Tamamo Nine didn’t mean much when she’d be served with a cherry on top soon, “As if you’d know, yes, I’ll have to stop that before I lose this one…”
The better details of her tail softened out into an amalgamous blob of pink, strawberry ice cream dripping off her faster than the body’s stuff, “Turn up the air conditioning, would you? I’m afraid I’ll completely melt before I’ve even finished…” Koyan’s tone was softened now with the rest of her as she fully accepted her fate and quietly pondered what to do next.
Ritsuka dutifully moved over to the thermostat and spun up to the maximum cold Chaldea could muster. Just shy of the arctic expanse outside, the fox would be alright for a while as long as she didn’t leave. Of course, as her body melded into a magecraft enhanced treat, she had no reason to with her human needs more and more whipped out of the picture.
“So like, what do I gotta do now!? You’re gonna be a huge messy beast with all that ice cream slipping and sliding everywhere!” Ritsuka heard about half of what the fox told her and understood less, “I can’t eat all of you!”
Koyan annoyedly pointed to her Master, “That’s enough! Leave me be!” There was a particularly noticeable bit of heft flying up armpits to the things themselves. Lard before settling the recipe in the freezer was par for the course and nothing too notable now that she was half and half in both woman and flavor, “I’ve grown tired of dealing with you, so there is nothing more you need to-”
“Nah, I wanna taste you when you’re done!” That perverted Master held their ground against the weakening front of a Servant frothing up the chilling, small room she’d been put in, “Plus, you’re missing the chocolate!”
“C-Chocolate!? I’ll admit that this… stomach is vanilla, yes, and that my tail has become strawberry I would assume, but chocolate is…” With her lower half ready for store shelves, any trouble with bodysuit was cemented along with whatever now popped out of them.
Sizeable breasts of a true temptress being forgotten in the midst of creamier pastures, they froze atop a mass of sugary excess. An enormous pear shape didn’t fit the flavor profile of the whole thing and thus went extinct for no fruit at all. Flabby rolls of tit flopped out of her bodysuit with a widened torso all around bringing her liminal obesity closer to its true potential.
“Yeah! Chocolate!” Rituska bounded over just to be hit with a wall of cold combining the air and aura of her one beloved dairy beast, “That’s what the suit’s for, right !? Choccy fox coated like a nice, big ice cream cone!”
The bodysuit Koyan wear was made of a sumptuous latex-like material made to stop anything from stabs to gunshots, so it’d been especially durable all throughout her unfortunate transformation. Though, now that she looked at it, there was something different about it now barring the vanilla streak lining it all the way down. The greater details down below were lost in all encompassing, lighter color and sheen of something thicker than breathable latex.
Dipping her body in melted chocolate wasn’t as much a fix for the lack of that third flavor as it was just another delicious piece of puzzle wrapping her cheeks and more in a crunchy outer shell for Ritsuka’s pleasure, “I bet it’s milk chocolate! Yeah milk !”
Milk cans under other circumstances, udders Koyan didn’t have once they’d filled out as the topmost rolls of a body made to melt into one blob anyways. There wasn’t so much a need for artisanship in the realm of a quick to eat treat like ice cream, so there wasn’t much for either to say about the final touches.
Blobby bingo wings pulsed down her arms before similarly getting touched up with brown chocolate, “This has taken quite too long, hasn’t it? It’s no wonder I decided such a time waster wasn’t fit for our arsenal…”
“Yeah, but like it’s pretty awesome isn’t it?” Thinking about the ramifications of NFF being able to make such destructive things beyond conventional weaponry didn’t register with Ritsuka, “I want more girls like you!”
“No… No, you don’t…” Koyan braced for the true final flourishes of the stuff rounding out her pretty face with a couple chins of vanilla slop then topped by simplified hair and fox ears matching their strawberry flavor with her mushy tail. The fox was ready to be served, “Please leave. I can’t even feel anything anymore and would rather be left alone…”
“Does this mean you’re done!? Can I taste you for real this time!? I’m gonna do it!” Ritsuka ran back to Koyan just to be slapped away with a sticky, fat handprint on her face, “I’m gonna do it!” The Master repeated the same thing again with yet another print sending her back, “I’m gonna-”
“I told you to leave!” As much as Koyan enjoyed hitting her Master, Ritsuka clearly enjoyed it just as much, “You
cannot
taste me like some free sample nonsense I already lobbied to criminalize! There is nothing that can make me-”
Ritsuka expertly crawled back to the thermostat with her gross fingers on the dial, “Okay but if you don’t let me, I’ll just turn up the heat! Can you stop me before you really start melting!?”
There was nothing to do but relent at that point without a fight. After all, Koyan was a practical woman that put her survival above anything, “F-Fine! You may have a single taste of my new form, but that’s all that I’ll allow!”
“Yay! Yay!” Ritsuka left her advantage over the fox for a quick bite of her body, “I know where I wanna go first!”
“I said only-” Her Master bounded over quicker than she expected and lunged towards her as an even hungrier beast than Koyan could ever be, landing right before that enormous, blob of meal, “B-Be careful you-”
The Servant was cut off by her Master sealing her words with a kiss. Ritsuka was a short girl, moreso than most of the skirts she chased, so she was on her tippy-toes to reach all the way to that creamy mountain to meet the fox’s unfeeling lips.
Stunned to inaction was giving too much benefit to a single doubt that Koyan had a single thought in her soft head. For the first time since being exploded into existence, the fox had nothing in particular darting around her head as a means to humanity’s end. No, even if she’d lost any sensation in the transfer from woman to product, there was a definite emotion welling up somewhere, cherry vanilla swirl blush proof enough, with Ritsuka’s tongue scraping the inner walls of her mouth.
Ritsuka broke from the kiss with a satisfied line of vanilla spit from her to Koyan, “Wow! Just like real ice cream! I can’t believe it!” Kissing was more an impulse than an actual expression when all she wanted was a quick taste.
“W-Wha-Why d-did you…” Koyan had a hard time recovering from her special treatment while her Master was perfectly fit to continue for more than a single mouthful, “Why are like this!?”
“I dunno… They all kinda say that, but I don’t get it! Mashu doesn’t even taste like an eggplant! Like at all!” Getting a literal taste of women throughout Chaldea seemed to be finally fruitful with a sweet treat of woman right in front of her, “But I still want some more, okay!?” She dropped down to her knees and hefted up part of the fox’s bloated, creamy hips as it squeezed out of her chocolate bodysuit on the side.
Though she couldn’t really feel it, Koyan instinctively cringed as her Master chomped into her haunches with the fox on the butcher’s block, “M-More!? I’ll be turned to nothing at this rate!”
Ritsuka didn’t react beyond an annoying thumbs up while she kept at slurping on premium grade slop, “E-Enjoy yourself while you’re still skinny then! I’m sure this is contagious!” Koyan wasn’t actually sure, but it made sense for something her conglomerate would make, “Little brat…”
Understanding what she was talking about didn’t matter for a single-minded commander like Ritsuka, so even as she could feel her belly quickly start to swell up with misplaced fat, she didn’t stop gnawing on her Servant’s melty leg. After all, what was better than one ice cream if not two?
