A cute little inflation story commissioned by  OrignalGiratine about... ten months ago, ahah. Just forgot to post it 'til now. whoops!

Pump, pump, pump… pump, pump… pump…

“There! That ought to do it!”

Nemidy’s muzzle broke into a smile, her tail swishing lightly as she closed the valve on the little inflatable Christmas tree she had just picked up.

On the nearby couch, Maple merely sighed. “I wanted a real tree…”

Nemidy’s smile turned a little sad as she turned to her girlfriend. “They’re all out, remember? Besides, money’s been kind of tight this season—”

“I know, I know, we’ve talked about this like a million times! I still want a real tree, though…” Maple flopped over, grumbling as she stared at the ceiling.

Nemidy shrugged. “What do you want me to do? Conjure a perfect Christmas tree out of thin air?”

“Conjure…” Maple’s furry green ears perked as she sat up straight. “That’s it! Magic!” She sprung off the couch and out of the room, leaving Nemidy to tilt her head and wonder what Maple would get herself into this time.

And this time, it seemed, Maple had found the spellbook she inherited from her grandparents. It was a thick, musty old tome, with more spells than Nemidy could count, written in odd languages not even Maple had mastered.

Even so, Maple was flipping through the pages, looking for that one spell she had just barely remembered… then, at last, she found it! “Fascimile-Reality Interchange,” she translated aloud.

Nemidy blinked. “I’m sorry, what?”

“It’s a spell that… well, it should turn our Christmas tree real! I should probably combine it with a growth spell just in case.” Maple pored over the text, straining to decipher the runes. Soon enough, though, she’d gotten the gist of it and the necessary incantation. ...Probably. Beside her, Nemidy just rolled her eyes. Of course there was a spell for that. There was a spell for everything.

Maple looked over the instructions again, brow furrowed. She was pretty sure she had it right, but if not… Well, she was pretty sure that wouldn’t matter in the end. “Alright, unless you want a face full of pine needles, stand back. I’ve never been that exact with growth spells.”

Nemidy duly took several steps back. For all her enthusiasm and family talent, Maple wasn’t exactly the best mage. In fact, they were hurting for cash specifically because of a “little mistake” with one of her more ambitious spells. Still, how bad could this one be…?

Maple recited the incantation as the spellbook began to glow. She focused all her thoughts on the toy Christmas tree before her, straining her magical energies, ensuring she didn’t trip over a single syllable… Eventually, the spellbook flashed with a burst light, signalling that the spell was complete!

But the tree was still plastic.

Nemidy felt a hollow feeling growing in her belly. It was never a good sign when nothing happened… or seemed to happen. “Maple…?”

Maple was starting to feel hollow herself, scanning over the instructions again to try to figure out what went wrong. The hollow feeling only grew as she realized that she had gotten… literally every word in the wrong place. The spell she actually weaved caused something real to become something fake, the fake thing being like the inflatable tree, and the target being herself and Nemidy! In fact, the only thing she was sure she got right was the growth spell, but since the tree was the same size…

“Maple?!” Nemidy called a little more panicked now, and for good reason. Her fur had turned slick and smooth like the plastic tree, she had grown a couple feet, and her chest had swelled out a size or two at least!

“S-sorry, Nemi— ulp!” She was cut off by the sudden feeling of growth, a gentle hiss ringing in her ears as her body hollowed out, fur turning to soft, shiny rubber… and her own bosoms blew up as well, to her embarrassment.

“That’s all you have to say?! Sorry?!” Nemidy snapped, ears flicking as they rubbed against the ceiling. The hissing in her ears was getting louder as she inflated faster and faster. If she was more level-headed, she might have thought to get outside, but she was a little too annoyed with Maple to think about anything like that.

Maple herself was too nervous to come up with such an idea, even as her own head rubbed against the ceiling. She noticed with a light blush that while she remained roughly proportional despite her growth, her and her lover’s chests and rears outpaced the rest of them just a little, exaggerating their curves more and more as they expanded.

“Well?” Nemidy broke the silence again. “What on Earth did you do to us?!”

“I-I… I messed up, alright? I meant to turn our tree from fake to real like us, but I got it all mixed up and turned us from real to fake like our tree! And I guess my growth spell doesn’t play nice with the other spell either…” She looked down, seeing mostly the pair of balloons that her chest had become. “Or it plays very nice, hehe!”

“I’m not in the mood right now…” Nemidy grumbled. Her head was bent down at an awkward angle, limbs ungracefully looking for room in the increasingly crowded out space. Maple had similar struggles, but when she tried to make herself more comfortable, she heard an ominous crack somewhere above her.

The two furs-turned-balloons exchanged worried glances. But for all their concern, they were more or less stuck where they were as air insisted on blowing them up bigger and bigger, at the expense of all the furniture they were crushing in the process. Not to mention, the inflation was still accelerating…

“Just how big did you want our tree?” Nemidy asked.

“I don’t know, ‘big’? N-not this big, I promise, but… magic’s tricky, okay?”

“Ohhh, trust me, I know.” Nemidy shot Maple a grumpy look.

“I’m sorry, okay? I’ll fix the house up after all this is over, promise!”

Nemidy sighed. “I’m sure you will, just—” Whatever she was about to say was cut off as their inflation suddenly tripled in speed! In mere moments the two anthros were pressed against one another, the walls and ceiling cracking and groaning as the pressure building within them yearned for escape… by any means necessary.

Helpless to even speak, Maple could only brace herself as the walls collapsed and the ceiling split open, causing her to puff out and bounce away from Nemidy and placing them on opposite sides of their ruined home.

But the state of their house was the last thing on their minds— the hissing within each of them and the creaking of their tautly stretched bodies drowned out all thought, leaving each alone in their own relentless expansion, even as their own bodies began to groan and strain from the redoubled pressure…

Soon, each girl had surpassed their home in size and then some, looking for all the world like exceptionally curvy parade balloons on their lawn. But they couldn’t see any of it, lost in a world of hissing and creaking and growing and stretching… growing louder… more intense… more strained… until…!

BLAM!

Both parade balloons exploded with a loud boom, scattering rubber scraps for miles. At the epicenter, the two of them sat, no worse for wear except for a bad dizzy spell. As that wore off, Nemidy could finally shriek at the rubble that was once their home.

“I-It’s okay, it’s okay! In fact, I know just the thing that could fix this!” Maple insisted.

Nemidy turned to call her out, but to her horror, Maple already had her spellbook open…
