>”Whoowee! Must be one heck of a party yer plannin’ for tonight, Pinkie!”
Applejack lifted the final chair, holding it over her head before walking to the table and setting it down at the last empty spot. Pinkie giggled.
>”I know! Thanks for helping me set up! I couldn’t have done it without you!”
Applejack smiled, and cleared her throat. Pinkie raised an eyebrow.
>”Ah it’s nothin’ Pinkie, just a little parched.”
Pinkie gasped.
>”No way! Me too! I’ll get us something to drink!”
Pinkie dashed to the snack table, already laden with food and drink. She poured two cups of fruit punch before handing one to Applejack, already finished her own cup on the way. Applejack tipped the whole cup in a single gulp, sighing in relief, while Pinkie made idle chatter.
>”-And so I told Gummy that he should start taking up-”
Applejack relaxed, used to the party girl’s loose mouth. She closed her eyes, blocking out the noise as she leaned against the wall, savouring the sweet taste of Pinkie Pie’s secret punch as it tickled her tastebuds on the way down her throat…
>”-And I mean, I even used great-great-Granny Pie’s  secret punch recipe! It’s supposed to make things big enough to match the occasion, using old fashioned earth tribe magic! And I thought that this is one big party so we would need big-big… huh?

Applejack barely responded, far too relaxed to-
>”WOAH NELLY!”
The farmer jolted into action, freeing her breasts from Pinkie Pie’s squeezing hands.
>”Hey! I wasn’t done!”
>”Pinkie Pie! Ya can’t just go around squeezin’ other girls apples! What’re ya thinkin’?
Pinkie crossed her arms, looking betrayed.
>”But they’re so bouncy and huge! When did you have work done? I never noticed!”
>”Whaddaya mean ‘huge’?! And ah ain't got no work done, they’re as big as they’ve… always… watermelons?”
Pinkie and Applejack stared wide eyed at Applejack’s swelling bust, gaping as it sloshed around with every movement. Applejack moaned, unbuttoning her now too-tight top to relieve the pressure and exposing her filled bra.
>”Holey cannoli, Applejack! Your bits are getting huge and milky! Normally everything just starts filling up with air! S-speaking of which, oooh…”
Pinkie’s hips began to widen as a faint hiss emanated from her core. A trio of bulges appeared under her t-shirt as her breasts and belly followed suit, slowly puffing up like a bundle of balloons. Applejack’s breasts continued to expand, her nipples visible as they leaked droplets of milk, rendering the material translucent. The farmer moaned, her massive tit’s once again feeling  constrained against her bra as they swelled another inch. Unfortunately, it had no buttons, and at this point was most certainly stuck…
BREAK

>”Ahh, ahh, mmh… Pinkie… What did did you do…?”
Pinkie Pie danced around the room slowly as her figure continued to puff up, her the flimsy yoga pants that she insisted on wearing beginning to show through as her ass and thighs ballooned, each thigh a foot wide, and an rump like two balloons that squeaked and creaked,rubbing together as she moved. Her tummy peeked out from under her shirt, swelling larger and larger as her breasts bounced around.
>”I told you A-ah-ah-Applejack! It’s Great-Granny Pie’s secret punch! It makes things big to match the occasion!”
Applejack could only moan in response to Pinkie, as her bra reached her breaking point, her breasts leaking rich cream as she slumped to the floor. Oddly, the fall didn’t hurt as much as expected…
Suddenly Pinkie Pie squealed, crossing her legs with a loud squeak before falling on her butt, which she bounced on gently, a good foot off the ground. Her arms wormed their way around her fat belly, finding their target between the party girl’s thighs, which they stroked and rubbed in earnest.
>”W-wow! I’ve never gotten this big before! This is gonna be some party!”
BREAK

Applejack’s bra snapped cleanly in two as the rate of growth for the two redoubled, both girls gasping and moaning in pleasure. Thin jets of milk spurted from Applejacks tits as the pressure was released, before slowing to thin streams that leaked straight down. Layers of muscle and fat began to thicken her thighs and belly as well, her old short-shorts tearing down the center as she began to grow a figure like Pinkie Pie.
Meanwhile, the Pinkster herself could barely breathe as she tugged at her stretchy pants, desperate to free her full, balloony rump from it’s confines and growing pressure. She couldn’t even reach around her fat tummy, being the size of a extra large exercise ball. Suddenly, her fingernail caught a loop of loose thread, the one flaw causing the whole structure to tear away, shredding itself into nothing and leaving Pinkie Pie in nothing but her flimsy underwear.
Applejack continued to plump up, her belly and hips rounding out to half of Pinkie’s size, while her breasts became enormous, sloshing about as each one was nearly a two square feet large. Applejack squeezed her massive tits together, admiring them as they oozed through her fingers, heavy and pliable. She brought one huge, puffy nipple to her mouth, sucking earnestly as the smooth and creamy milk flowed so easily down her throat. She squeezed the other nipple as she sucked, shooting a thick jet of milk directly into Pinkie’s awaiting mouth, who slurped it up in earnest.
BREAK

Suddenly everything stopped.
The hissing coming from Pinkie’s humungous tummy, the sloshing from Applejacks tits, and the moaning and squealing of both Ponies. Shocked by the change of tone, both girls stood and began spouting apologies for letting themselves go in front of the other.
>”I-it just felt so good and-”
>”-I-I couldn’t help myself, I just had to-”
Then they noticed each other.
Applejack gaped. Pinkie Pie gaped.
Applejack was a enormous, with huge thighs and an ass at least  four feet across. She had immense, full, milky breasts that sloshed and dripped thick, delicious fluid with every move, looking perfectly squeezable and heavy. Despite everything being huge and hefty, she felt… Stronger. Her big belly and massive thighs weren’t overly muscular or flabby, but a perfect mix of the two, perfectly plush and soft, and capable of lifting her bulk with little trouble.
Pinkie Pie was immense, boasting a rump and hips that formed a wall behind her, at least at least seven feet wide, and three feet behind her, squeaking and groaning as she swayed left to right in anxiousness. Her stomach was like an overinflated punch balloon, jiggling in every direction as she idly poked at it, her fingers sinking deep and causing a satisfying creak. Her breasts were far behind in terms of size when compared to the farm girls, but they were still larger than any old breasts, about the size of two large balloons and even fatter nipples than Applejack’s. Her whole body was light and puffy, capable of moving with the greatest of ease, albeit slowly as she would mostly be drifting around lazily.
BREAK

Pinkie Pie’s panties snapped, causing her to gasp and attempt to stroke her pussy, her arm failing to reach around her big, creaky belly as she shuddered and moaned, her whole body squeaking as she rubbed her thighs together instead.
>”A-Ah-Applejack! I-I’m so close-hah-hah-help…”
Applejack smiled, despite everything, slowly walking up to the dripping party girl, and whispering in her ear…
>”Don’t fret, sugarcube. It was a team effort from the get-go…”
Pinkie Pie squealed in pleasure as Applejack forced her thighs around Pinkie Pies hips, squeaking creaking as the farmers, well-toned muscle rubbed against her delicate, rubbery skin. The two began to hump each others thighs, the feeling of each other providing exactly what was missing in each of them. Pinkie’s swollen, air-filled pussy dribbled against AJ’s tough skin, the roughness and hardness beating against it perfectly, while Applejack’s puffy pussy was tickled perfectly by Pinkie’s smooth, pliable thighs. Pinkie and Applejack locked together, Pinkie Pie suckling on one of Applejack’s nipples, while Applejack squeezed Pinkie Pie wherever she could reach. Both girls climaxed, sweaty and red faced, squealing as juice dribbled down their thighs. Huffing and puffing, both girls smiled at each other.
>”Ya make a nice partner Pinkie, I can see mahself helpin’ ya set up parties more often!”
Pinkie Pie giggled, and opened her mouth to speak, but she caught herself, as if listening intently…
Footsteps. Pinkie grew a massive smirk
>”Sssh, do you hear that?! It's the other girls! And that means…”
Applejack’s breasts gurgled as they resumed swelling, while the hissing sound deep within Pinkie Pie made its return. Seems that this party just got a whole lot bigger...
