In the land of Equestria, alicorns have long been synonymous with grace, majesty, and authority. The very image of one brought these words, among others, to the minds of ponies all over Equestria. It was rather unusual to see one groveling, head bent in shame and nearly prostrate on the ground.

Then again, Twilight Sparkle was never the model example of an alicorn.

“I’m sorry! I’m so very, very, sorry! I didn’t know they were going to summon you for something like this!”

Princess Luna stood in Twilight’s castle, surveying the scene before her. Rainbow Dash and Applejack stood nose to nose, glaring into the other’s eyes. Twilight was off to the side, bowing and pleading as if she were off to the gallows, and Rarity stood further back, a playful grin on the crook of her lips.

“What, pray tell, is this about?”

Rainbow Dash took this opportunity to pry her gaze from her rival.

“Applejack still won’t admit I’m braver than she is! We’ve done all sorts of stunts, but she keeps saying my wings are giving me the edge instead of just admitting she lost!”

Applejack pushed the brash pegasus aside. “There’s gotta be some way we can settle this once and for all, your highness!”

Twilight lifted her head slightly, a sheepish grin on her lips. “See? It’s nothing! You should go back to Cant-”

“A contest of champions!” Luna declared with an outstretched hoof. Everyone present stopped to look at the princess as if she had declared herself The Queen of Panties.

“Uhhh, pardon?” Applejack asked.

Luna stepped forward, her nose held high into the air. “More than a thousand years ago, ponies from different tribes, villages, or groups would oftentimes compete to see who was the superior one, or just to settle a dispute. Though several ponies tried to find challenges that would be fair to every tribe of pony, only one contest was truly fair. The airy berry challenge!”

Luna turned to the ponies gathered, only to see confusion upon their face. “Hmm, curious. I thought for sure my presentation should have astounded you.”

“What the hay is an ‘airy berry’?”

“Yeah,” Rainbow said, interrputing Applejack. “It doesn’t sound very impressive.”

Twilight similarly looked confused. “I’ve studied ancient pony history and never heard of such contests, or airy berries. How could this be?”

“Of course not! Many rituals and practices eluded even the most devoted scholars. Airy berries are simply frost berries from the edge of the Crystal Kingdom that have fermented in clouds. The result is a berry that absorbs moisture and produces an overabundance of air. Allow me to demonstrate.”

Luna flared her horn to life and picked up a deflated balloon off the table in front of her. Grabbing a nearby glass of water, she tipped a small amount inside, filling the very bottom of the balloon. Next, she opened her saddlebags and produced a light blue berry which she dropped in the balloon. Squeezing the neck of the balloon shut, she smiled as it billowed outward, quickly growing to it’s full nine inch size.

Scratching her neck, Applejack cleared her throat. “Begging your pardon, Princess, that’s a neat trick and all, but how is that a contest of any kind?”

“Yeah, it just looks like some dumb foals thing,” Rainbow added.

“You eat them.”

Everyone present looked to Luna.

“Wha-what?!” Twilight sputtered.

“You heard me! Both contestants are offered a large amount of berries to gorge themselves upon. They do this divided by a barrier so neither knows how much the other ate. The bravest pony is the one who ate the most berries. The loser is left to the whims of the crowd present,” Luna explained.

“I don’t rightly know if I’m up for this,” Applejack said, stepping backwards.

Rainbow turned, a cocky grin upon her face. “Hah! Chicken! I’ll totally do it!” Rainbow shouted, throwing open her wings in pride.

Luna smirked at Rainbow’s outburst.

She took the bait quite easily.

“Do you forfeit, fair Applejack?”

Shrugging her shoulders, the cowpony stepped forward. “I suppose I don’t have a choice. I’m in.”

“Very well! It is decided! Tomorrow, Applejack and Rainbow Dash will compete to see who truly is the bravest pony, and Twilight Sparkle will keep record.”

“M-me?” Twilight asked, pointing a hoof at herself.

“Of course. You are the resident scholar. I expect you to live up to your role.”

“Yes, Princess Luna.”

With little fanfare, Luna disappeared with a teleport. Rainbow and Applejack turned to each other, a glint of rivalry in their eyes. “Guess we find out for sure tomorrow, huh?”

Applejack nodded. “I hope you’re ready to lose.”

Flapping her wings, Rainbow took flight. “Not a chance! See you tomorrow, Applesmack!”

The next day Twilight led everyone to a huge empty room beneath her castle. With at least fifty feet from the floor to the ceiling, there was plenty of room for any sort of contest. Being underground, there were no windows nor lights, but the shimmering crystal put off enough light to see.

“Tis a spacious room,” Luna remarked. “I wonder what purpose it serves?”

Twilight motioned Luna to the back of the room with her hoof. On the wall was a small inscription and little else. “I’m not sure since I can’t read this, but it looks similar to the text in the armory of Canterlot Castle. It seems unusual though if it is an armory, since the castle is supposed to provide me with everything I need to serve, yet there’s no troops or weapons to be found.

Luna, being older than dirt, decided to read the text herself.

A-R-M-O-R-Y

G-L

L-O-L

Luna smirked to herself. “Seems a mystery we may never solve. No matter. We came here to decide something else altogether.”

With a blinding flash, a barrel full of airy berries, a dividing wall, two tables, and two bowls appeared.

“Everypony please step forward!” Luna announced.

Rainbow Dash, Applejack, Rarity, and Twilight Sparkle marched forward.

“Today, we are gathered to decide once and for all, who the bravest pony is between Applejack, and Rainbow Dash. Twilight Sparkle will be the resident scholar to record the event, and Rarity will be a witness. Competitors, are you ready?”

“Sure am!” Applejack announced.

“A-always ready,” Rainbow said, with a little less confidence than her opponent.

Luna nodded. “Very well! Competitors, take your positions!”

Needing no further prompting, both ponies walked to their respective bowl, brimming over the top with airy berries. Rainbow stared at the fruit with an apprehensive gleam.

“P-Princess Luna?”

“Yes, Rainbow Dash?”

“Has a pony ever, umm you know… popped before?”

Tapping her chin, Luna hummed thoughtfully. “I can’t say I’ve ever heard of it happening, but what kind of contest of bravery would this be without stakes?”

Swallowing the spit gathered in her mouth, Rainbow nodded. “Right. I guess...”

“Contestants! Approach your bowl!”

Rainbow and Applejack both marched forward, the wall eventually separating them. The “bowl” in question was not a normal bowl somepony might eat from. It was larger, much larger, like a wok. The berries sat piled high, waiting to be greedily shoveled into a pony’s maw.

“I wonder how many Applejack will eat? She’s a scaredy pony. I bet she doesn’t eat more than a hoofful.

Despite her self assurances, Rainbow wasn’t very confident in this theory. She could easily imagine Applejack dumping a couple more just to make sure she beat Rainbow.

Being a big inflated pony probably sucks. Maybe I should just back out.

Almost immediately, Rainbow slapped herself.

“Is something wrong, Rainbow Dash?” Twilight asked with that pathetic look of concern in her eyes.

“No! I mean, nah. I’m fine. Let’s do this!”

“I won’t let Applejack win by default! She’ll have to be humiliated too!”

“Contestants at the ready!” Luna shouted.

Rainbow dug her hoof in, as if she were about to start a race.

“BEGIN!”

The princess’ shout rattled Rainbow once more. With a shaky hoof, she scooped up some berries and crammed them in her mouth. Much to her surprise, they slid and squeezed effortlessly, going down her gullet with ease. She scooped up some more and pushed them down, trying to estimate how big she’d get from Luna’s demonstration.

Just one more. Surely that would beat Applejack.

Once more she swiped up some of the berries and tilted her head back, letting them go down her throat. Swallowing the last one, Rainbow let a triumphant grin spread across her lips. All she had to do now was wait to be declared the victor.

“Are both contestants finished?” Luna asked.

“Yes, your highness,” Rainbow said as she felt a bit of pressure spike in her gut.

*Buuu-rap!*

An absolutely tremendous belch rattled the thin barrier between Rainbow and Applejack.

“I think so, Princess…”

Loud hissing filled the air. The barrier, glowing in blue magic, was torn from between them. Rainbow’s eyes bulged at the nearly empty bowl, and then at Applejack who had already swollen to the point where her hooves couldn’t touch the ground. Those apples emblazoned on her flanks stretched widely, each around a foot wide.

Luna shook her head. “Tsk, tsk tsk. It appears you have lost, Rainbow Dash.”

Rainbow felt her stomach tighten and swell out slowly. Nevertheless, she couldn’t help but smirk at her opponent’s predicament. “Doesn’t look like I lost from where I’m standing.”

In a flash, Applejack returned to her normal, fit self.

“No, Rainbow Dash,” Princess Luna began. “Applejack was the braver pony, so she returns to normal. You however-”

A feeling of dread welled up in Rainbow’s throat as she felt the bottom of her stomach push into the ground.

“- will be our plaything.”

“What?! I don’t remember agreeing to that!”

Applejack gave a firm smack on Rainbow’s bulging side which echoed like a balloon, making her cry out. “You were so gung-ho about showing me up that ya didn’t even consider losing, did ya?”

“Okay, fine! I lost! Do whatever it is you wanna do so I can deflate already!” Rainbow shouted as her hooves left the ground.

Two white hooves wrapped around Rainbow’s bloating body. “You heard her, everypony. Let’s have some fun.”

Rearing back, Rarity threw out her legs. They connected with a satisfying *bong!* sending Rainbow flying through the air.

“Ahhhh! Stoppit!”

Applejack reared back, heedless of Rainbow’s protests and bumped the pegasus back, sending her spiraling through the air.

“Ah! What great fun!” Luna exclaimed. “An impromptu game of volleyball! Twilight! You’re on my team.”

Twilight, who up until now was more or less too confused to say much, bit her cheek and gave a tentative nod. Casting a quick spell, Luna scorched an outline of a volleyball court across the crystal floor. She reached up just in time to catch the swelling pegasus with her hoof. Cocking a sly grin at Applejack and Rarity, she cleared her throat.

“So it’s the princesses versus the commoners. I wonder how we could make this more exciting.”

“How about, when one team scores, they get to add something to the ball?” Rarity suggested.

“I’m not a bal-Mphm!” Rainbow shouted before being silenced by Luna’s hoof.

“That is a grand idea!” Luna said. “To top it off whichever team wins will end up giving the ball her final humiliation.”

Applejack straightened her hat. “Alright, yer on!”

With a playful giggle, Luna lifted her “ball” up and bumped it with her front hooves.

*boong!*

Rainbow sailed through the air lazily right toward Rarity who answered with a surprisingly strong punch.

“Ooof! Hey!” Rainbow protested.

Her anger fell on deaf ears as Rainbow wobbled through the air toward Twilight. She stared, petrified as her friend tumbled her way like a beachball. She stuck out her hoof, barely making a dent in the stretchy balloon pegasus. Rainbow bounced a feeble foot or so before hitting the ground on her side.

“Haha! That’s fifteen ta nothin!” Applejack cackled.

“Twiliiiight, you’re supposed to hit it over the line,” Luna whined. “Haven’t you ever played volleyball before?”

Folding her ears, Twilight blushed. “I have, Princess, just… not using one of my friends as the ball.”

Luna strutted over and swatted Rainbow with her tail, rolling the bloated pegasus across the line. “It’s the same thing, so get your head in the game.”

Sticking out her hoof, Applejack caught Rainbow with her hoof. Looking her in the eyes, she gave the pegasus a crooked grin. “Now what to do with you… I know!”

Grabbing Rainbow by the sides, Applejack took a deep breath and put her lips to Rainbow’s.

*Fwoosh!*

The first breath added several inches to the pegasus’ diameter, pulling her hooves up.

*Fwooosh!*

Another strong gush of air ballooned the pegasus further. Her wings stuck straight up as she bloated outward.

Applejack winked before taking one more breath of air.

“No! Applejack, don-phwm!”

*Fwooooooooooosh!”

Before, Rainbow was a more oblong, roundish shape. With this last mighty breath, her extremities pulled in and tightened as she rounded out into a seven foot round ball shape. Even her head was stuck, unable to move in any meaningful way.

And with that, Applejack finally released the ballooned pony from her grip. She wobbled slightly, dizzy on her hooves. “I think I overdone it there a moment…”

“Uuuugh… Applejack… I’m so huge-mph!”

Rainbow’s protests were cut off with an orange hoof. “Now, now, I ain’t ever heard no balloon talk, so keep quiet there, missy.”

Rearing back, Applejack gave her ball a sharp kick, sending her over the line.

“It’s coming your way, Twilight!” Luna shouted.

Rearing back, Twilight gave the spherical pegasus a strong hoof, sending her flying back across the line. Rarity watched as the ball moved lazily her way. Stepping sideways, she bumped the bloated pegasus with her flank and a giggle, sending her back across the line. Luna rushed forward and spiked Rainbow a little too hard, sending her flying over the side line.

“That’s out!” Applejack called.

“I knew I should have made the court larger,” Luna groused.

“Thirty to nothing, isn’t that right, Jackie?”

Applejack fetched the ball and threw it to her partner. “Sure sounds right to me. She’s all yours.”

Rarity caught the bouncing bloated pegasus and looked into her eyes. “Great, because I have a fantastic idea.”

Without another word, Rarity traipsed out of the room with a spring in her step, humming a merry little tune while everypony watched. The room fell silent as she shut the door behind her.

“Where do you reckon she’s going?” Applejack asked.

Luna gave a shrug.

The door flew open a few moments later as Rarity returned, a garden hose in her magical grasp. Walking around the edge of the rotund pegasus, she gave a quick giggle. “The game has been a little too easy so far. Let’s add a little ‘fluid dynamics’, shall we?”

With that, Rarity unceremoniously plugged the nozzle in Rainbow’s rear end.

“RA-RA-RARITEEEE!”

Rainbow’s bloated form wobbled and stretched as water gushed inside, filling her with gallons of water. The sound of sloshing echoed deep inside her as she filled larger and larger. It wasn’t until her body surpassed the size of a weather balloon that she felt a new sensation. Every time Rarity touched her ballooning body, every adjustment of the nozzle, every gallon of fluid that filled her, all of it increased a tingling in her lower parts.

“Ooooh… that’s… that’s… not so bad,” Rainbow finally sputtered as a blush broke out on her face.

Before she could drink in the pleasure any longer, Rarity pulled out the hose and turned the nozzle off. “That’s enough for now, I should think.”

“Nu-no, wait-”

Rainbow’s protests fell short as Rarity picked the sloshy pegasus up and bopped her back across the line. With the unusual mixture of air and water, Rainbow spiraled unpredictably, but Luna was no novice. Intercepting the bloated pegasus, she bopped her back. The sloshing and roiling water inside Rainbow made her a much less predictable target, despite her size. Applejack rushed the net and bumped her with her head, but it was a glancing blow. With an angry slosh, Rainbow wobbled and rolled off the side of Applejack’s head.

“Ha-HA! Fifteen to thirty! We’re catching up!” Luna announced playfully.

With a resignated sigh, Applejack pushed the ball back to the other side of the court, getting a low moan from the pegasus in the process.

Luna’s hooves clamped onto Rainbow’s swollen sides. “Now then, I wonder what mischief ilI should conjure upon thee.”

Slowly, she traced her hoof around the ballooned mare, easing out pleasured moans from her. Upon reaching her rear, Luna’s eyes lit up.

“Ahhh! I have a most wonderful idea!”

Sparking her horn to life, Luna fired a concentrated bolt of magic right below Dash’s puffy lips.

“Ooooh… what… what was that?”

Luna remained silent, she grinned at her handiwork. The tiny teats beneath Rainbow’s slit bulged outward like twin waterballoons. The nipples on the end quickly engorged with milk. Two white dots appeared on their tips.

A giggle tickled out between Rarity’s lips. “Oh, ho, my. This is quite the intriguing development. Perhaps we should have let you score sooner.”

As Rainbow’s new assets grew more and more, filling with milk, she started to pant. “Unnnh! They feel-huff-huff- so big!” she sputtered.

Luna gently prodded the sloshy milkbags which were now larger than one of Pinkie’s party balloons. Her nips responded in kind with a long stream of milk which shot several feet across the makeshift volleyball court.

“Ssstop… teasing me!” Rainbow begged.

“Sorry, Rainbow Dash, but our game is not over. You still have work to do,” Luna said. Lifting the pegasus once more, she battered it with her hoof, sending her flying.

“Yeehaw!”

Rearing back, Applejack gave a swift kick, her hooves sinking several feet into the ballooned mare. Spiraling through the air, Rainbow’s sloshing and growing milkbags sprayed thin lines of milk all over the court as she lazily bounced over to Twilight.

“Uhhh, ummm…”

Looking around for guidance or sanity, the purple alicorn found none, so she opted to bop Rainbow back with a weak strike instead. Sailing through the air, a stream of milk struck Twilight across the face.

“Ewww! Gross”

Spitting the offending substance out, she smacked her lips and accidentally let some cross her tongue.

“Oh. That… is… ummm, pretty good actually,” Twilight admitted with a blush.

Luna gave the younger alicorn a hint of a smile as Rarity pushed the ball back toward her. Luna ran forward to intercept it, when the weight of Rainbow’s burgeoning tits pushed her further back than anticipated. The punch meant for Rainbow’s mid-section was a glancing blow, sending the bloated pegasus bouncing a meager foot before hitting the ground.

“Forty-five to fifteen. Are you two even trying anymore?” Applejack teased.

With a frustrated grunt, Luna rolled the rotund pegasus across the line to Applejack’s waiting hooves.

“Any plans in particular, darling?” Rarity asked.

Applejack rolled Rainbow to the corner and pulled a sheet off of a nearby helium canister. “I remembered Pinkie leaving this here after Twi’s last birthday party. Thought it might make things easier for our opponents. They obviously need all the help they can get.”

Luna growled, but Twilight was still licking her lips, entranced by the taste left behind.

“A-Applejack, I’m big enough. Just help me get off, please!”

Applejack shook her head. “No can do, sugarcube, but don’t you worry. We’ll take good care of you once our game is over.”

Sticking the helium nozzle deep inside Rainbow’s plothole, Applejack gave the valve a hefty spin. An angry hiss started up deep inside the pegasus as her stubby limbs finally pulled completely inside the massive sphere she had become.

“Oh goddesses! It gets more intense the bigger I get!”

Applejack smacked Rainbow’s tightening and billowing ass, watching as her entire body shook from the impact. The bloated and taut milkbags were around three feet in diameter each and spraying constant streams of milk as she inflated larger and larger.

*pssssssSSSHHHH!*

The noise from inside the ballooning pegasus intensified as Applejack turned the knob all the way.

“Applejack, pleeaaaase!” Rainbow panted between gasps of pleasure.

At around fifteen feet, the helium tank finally ran out of air, giving the beleaguered pegasus a little cause to relax. Applejack kicked the canister aside with a huff. “Dagnabbit, Pinkie. I figured you woulda left more than that.”

Turning her attention to the new and improved ball, Applejack stood on her hind legs and rolled Rainbow back onto the court. Sloshing water and pathetic mewling are all the pegasus could muster, given her situation.

“Alright y’all, let’s get back to it!”

Bucking with all of her strength, Applejack nailed Rainbow with her powerful legs, making a loud and deep *DOING* echo throughout the room.

The huge target floated lazily through the air, only slightly weighed down by the water and milky funbags given the helium that was just forced inside her. Luna rallied and easily hit the giant fifteen foot round blimpmare, sending her back across the line.

Not to be outdone, Rarity answered by with a vicious spike… which wasn’t all that vicious considering her target. Nevertheless, Rainbow’s moans made it clear she felt it.

Back and forth Rainbow bounced, her arousal only rising from the rough handling she had no choice but to endure. On a particularly strong headbop, Applejack sent Rainbow flying toward the middle of the her opponent’s court.

“I’ve got it!” Twilight shouted.

“Nay, she’s mine!” Luna replied.

Seeing that Luna was insistent, Twilight stopped, but she had slammed her hooves down in a puddle of milk that had accumulated during the game.

“Look out!” Twilight screamed as she careened right toward Luna.

Unfortunately, neither pony could stop in time, leading them to crash right into each other.

The alicorns shook off the hit just in time to hear Rainbow softly hit the court behind them.

“And that’s the game!” Applejack hollered.

“No fair! The prissy one shouldn’t be this good at volleyball!” Luna protested.

Rarity walked over and hoofbumped Applejack. “Come now Princess, you really shouldn’t underestimate your opponents. It’s bad form.”

With a flick of cerulean magic, Luna neatly deposited the inflated equine on Rarity and Applejack’s side of the court. “Fine, I suppose it’s only fair the winners choose her final punishment.”

“Ngggh… mmmmmnnnn… I don’t care what you do anymore, please just let me get off!” Rainbow shouted as she wobbled impatiently.

“Luna, darling,” Rarity began, “ a pony of your magical nature wouldn’t happen to have access to an air compressor, would you?”

With a sour frown, Luna flickered a large red air compressor into existence.

“I had planned to use it when we won…”

Lifting the hose, Rarity gave a ladylike giggle. “Unfortunately, it looks like I’ll be doing the honors.”

With her magic, she stuck the hose into Rainbow’s mouth with a devious grin. Her hoof flicked the switch, jerking the house to life.

“Jackie dear, plug her up if you wouldn’t mind.”

With a grin of her own, Applejack grabbed the garden hose still sitting in the room and slid it between Rainbow’s ballooned and buttcheeks. After a quick adjustment, a deep sloshing could be heard deep inside the blimping pegasus as gallons of water started to fill the empty space inside. Wobbling with the motions, Rainbow’s sphere of a body ballooned outwards, taking up much more space.

“Well? Are you two going to watch, or have some fun?” Rarity teased.

“I-I’m so very confused. Is this a ummm… orgy or something?” Twilight asked, a sheer blush crossing her cheeks.

The lunar princess flapped her wings and took flight, landing on the soft expanse Rainbow’s body had become. “Stop asking so many questions and just have some fun.”

Luna’s statement sent the wheels turning. Licking her lips, Twilight could still taste traces of the sweet milk that had splashed her in the face. She slinked around the widening expanse of Rainbow’s body and looked at her rear end.

The waterhose lodged in her puffy ponut pumped gallon after gallon of water into the pegasus’ burgeoning form. Below that sat Rainbow’s engorged marehood, looking like two stretched balloons squished together and dripping with arousal.

Twilight’s eyes lowered still to the taut funbags bulging and swollen with milk, two lazy streams dripping off of them and puddling on the floor. Wrapping her lips around one of the puffy nipples, she nearly choked in surprise as it pumped a gush of milk down her throat. Gulping like mad, she swallowed mouthful after mouthful of the sweet delicious milk, feeling her middle swell with the new weight.

Meanwhile, Luna found her own spot of heaven, sinking into the huge blimp Rainbow was rapidly swelling into. She squirmed and touched her marehood, rubbing herself like mad as Rainbow continued her job as her cushion.

Applejack found herself entertained with Rainbow’s plump pussy lips. Dragging her tongue across them, she moaned in delight at the response she earned from the pegasus. She didn’t even notice the gush of milk that Twilight received in response, pushing the purple mare’s belly closer to the floor. She traced the outside of those swollen lips and parted them with her tongue, each time earning more jerks and muffled moans from Rainbow. Looking to her right, she saw the barrel of air berries, untouched from their competition.

“Waste not, want not!”

Scooping up a hoofful of the berries, she pushed them between those bloated lips, squeezing them inside. Angry hisses of air escaped her canal as Applejack crammed more and more of the berries between those plump pussy lips. She only stopped once she couldn’t reach any more of the berries.

“Time for your reward, sugarcube.”

Slowly, and with deliberate movements, she dragged her tongue across Rainbow’s marehood. They squeezed and throbbed with pleasure, letting a hiss or two of air bloating her canal and womb escape.

“There’s more where that came from.”

Rarity loved the finer points of inflation. The domination, the ruling, the utter power she held over those who were beneath her.

It only stood to reason she would enjoy standing on the air compressor hose, building up a huge amount of air.

Rainbow didn’t even realize something was up until the air flow slackened to almost nothing. It wasn’t until she opened her eyes and saw the five foot bulge looming behind Rarity did she also see the devilish grin on her face.

For some reason, despite being a thirty foot round balloon, this bothered her. She shook her head, pleading with Rarity not to let it go. It never really occurred to her where it should go, just that it shouldn’t go in her. Shaking her head madly, eyes wide with fear and fighting the immense pleasure Applejack was providing her with, she screamed internally.

Needless to say, that really got Rarity’s motor running. Pressing a hoof across her marehood, she smiled, pleased with her results.

Luna’s self ministrations became a blur as her hoof moved across her needy mound. Her other hoof was occupied with striking Rainbow’s blimped form like a drum, enjoying the echos deep inside her. With each hit, she felt the cushion beneath her wobble and bulge.

“Ooooh, yes. Just a bit more…”

Twilight let the nipple in her mouth go free.

*Buuurapt!*

Stranded atop her swollen belly, she idly reached for the next nipple sitting on the other crotchtit, fit to bursting with milk. When she realized she couldn’t move and couldn’t reach it, she lit up her horn instead. The enormous milkbag started pumping out more milk at the minor touch forcing Twilight to hurriedly plop the nipple in her mouth, lest anymore milk be wasted. Closing her eyes once more, she resumed her swelling as more and more milk filled her taut belly, raising her higher on it’s expanse.

The hose must have had an enchantment. There simply no other way for Rarity to explain how it could stand the immense pressure she was holding back. The hose bulge behind her was more than seven feet tall, and the rest of the hose was bulging all the way to the air compressor where it whined in protest.

“Oh darling, I hope you enjoy this as much as I will,” Rarity said, rubbing her wet marehood. Stepping to the side, the angry bulge shot forward, pushing into the pegasus with a cataclysmic *Whoosh!*

Luna panted wildly, her hoof thrumming against Rainbow in violent pleasure, her other hoof coaxing out an orgasm. Her eyes rolled in the back of her head as she thrusted against her hoof, generous amounts of marecum soaking the fur beneath her. So enraptured she was in her bliss, she barely felt the burst of air explode Rainbow’s blimp body outward and send her into the air like a trampoline, nor did she care too much that she was coming very close to the ceiling.

Applejack felt the first hint of something wrong when the pussy lips she was teasing parted slightly and let out a stream of marecum. The next thing she knew, she was pressed back against the wall, face full of Rainbow’s marehood. Beside her, Twilight fared no better as great gushes of milk forced themselves down her throat and filled her like a waterballoon. The purple alicorn grew ever larger, now unable to even pull away or spit out the nipple in her mouth.

All at once, the garden hose and the air compressor hose shot out of Rainbow’s holes as she swelled to fill the space between the floor and ceiling. Where there was once space to play an unusual game of volleyball, there was now only a blue vast blimp, taking up most of the room.

Rarity finally came, her hoof now covered in her own juices. Recovering from her exquisite joy, she stood up, her hooves resting on Rainbow’s ballooned form and planted a kiss on her cheek.

“Absolutely marvelous, darling.”

“Guh…” was all Rainbow could manage between loosening pressure and orgasmic bliss.

~Thirty minutes later…

Rainbow Dash had finally deflated to the point where Applejack could free herself. Of course, she couldn’t leave Twilight behind, so she put her hooves on the eight foot milk filled sphere the alicorn had become and rolled her to the middle of the room.

Luna, having the benefit of magic and the lucidity to use it, had escaped the pocket she had found herself in when Rainbow pancaked her between the ceiling. She was standing near Rarity, giggling about something once Applejack finally rolled Twilight over to them.

“Good of you to join us,” Rarity said.

“Well, it took quite awhile for her to shrink down a bit, “Applejack explained.

“If Rainbow’s moans were any indication, you rewarded her quite well,” Luna said.

A blush crossed Applejack’s cheeks. “Well, I couldn’t exactly move, might as well keep myself occupied, I thought.”

Moans between pleasure and exhaustion escaped Rainbow’s lips.

“Th-that was…”

“Awesome?” Rarity proffered.

“Yeah, sure. Am I stuck like this?”

Luna shook her head. “The air will escape on it’s own l, but you will have… shall we say, generous tits for a day or two that will require milking.”

“Guess I’m calling in tomorrow…”

Luna looked at the milk filled balloon Twilight had become. “I hope you know that some discretion should be used with your recording of this event.”

Twilight looked up as much as her head could with a drunklike expression on her face. “I was thinking something like, Applejack wins.”

Luna nodded with a smile. “Very good. I think I’ll reward your diligent note taking with a one on one shower between you and me.”

“”I’d like that very much. Being so big and huge feels wonderful, but there’s just this itch I can’t seem to scratch…”

Rarity lifted a hoof with a frown. “Speaking of showers, this entire room could use a thorough cleaning.”

Puddles of marecum, milk, and water pooled in spots around the room.

“Too bad we don’t have access to Pinkie’s party vacuum. It’d be clean in no time.” Applejack said wistfully.

A milky burp left Twilight’s lips. “Speaking of Pinkie Pie, maybe we should get her in on thi-” a blue hoof cut off her thought.

“Nay! Speak no further!” Luna shouted.

“Princess Luna, whatever is the matter?” Rarity asked.

“I have seen Pinkie Pie’s dreams. They are… apocalyptic in nature. That mare has no limits, doesn’t understand the meaning of small. Invite her to a session like this, and you do so at your peril.”

Applejack and Rarity swapped nervous glances.

“Right, we’ll keep this from pinks then.”

Rarity nodded in agreement. “It will be just between us.”

In the kitchen of Sugarcube Corner, Pinkie Pie was busy vigorously stirring some brownie mix, her tongue peeking through her lips in concentration. All of a sudden, her ears flopped, her tail twitched, her eyelids flapped, her back itched, and her hoof ached.

“Twitcha twitch! That one means… somepony is keeping a very fun secret from me!”

Putting the brownie mix on the table, she sat down, deep in thought.

“Looks like I’ll have to find out what it is all on my own.”

Author's Note

Oh god what am I doing/what have I done.
