Twilight's Key Party

Pinkie Pie hopped down the Hall of Hooves towards the organ room, the blue present bouncing precariously on her back. Rainbow Dash flew behind, clearly agitated.

“I can’t believe Twilight wouldn’t let us change partners!” the Pegasus complained. “Now I don’t get to be with Applejack!”

They entered into the dimly lit organ room. The organ sat at the back of the room, surrounded by two candelabras and two stone Pegasai, carved as if they were guarding it. A large red carpet trailed from the entrance to the stairs below the organ. The walls were decorated with hanging cloth banners and ornate archways.

Pinkie Pie grew excited at the sight of the organ and dashed over, dropping her bags and present on the floor. When she got closer, she saw a large yellow note taped over the keys, reading “please do not play the organ.” Pinkie frowned and trotted back to her bags.

“What are they even going to do together?” Rainbow Dash continued lamenting, dropping her bags on the ground, her voice echoing against the stone walls. “Rarity’s a frilly filly and Applejack’s a cow pony! One likes fashion and the other likes hard work! The only thing they have in common is that they’re both mares who live in Ponyville!”

Rainbow Dash started flying back and forth in the air, as if she were pacing. “I’d be so much better with Applejack! We could hoof-wrestle, or have a bucking contest, or if we’re stuck in the library, we could see who could carry the most books. But this? This is the worst!” She flung her arms emphatically, when Pinkie suddenly appeared in her flight path. “Waaah!” Rainbow exclaimed, coming to a stop mid air.

Pinkie Pie was floating at the same height as Rainbow Dash, her body tied to a dozen strings which were tied to a dozen balloons, which were holding her up. She frowned with concern, “I’m sure it’s not that bad, right?” she offered.

Rainbow Dash shook her head. “It is that bad! What are they going to do? Play checkers?”

Pinkie made a silly face. “I’m sure they’ll find something to do! Rarity’s pretty creative.”

“Yeah,” Rainbow said without confidence. She flew higher and started pacing again. “Rarity’s probably gonna dress up in one of those ridiculous outfits, and Applejack is totally going to reject her! There’s no way she’d think it was beautiful and start making out with her. It’s just not gonna happen!” Rainbow said, trying to convince herself.

Pinkie pulled another balloon from nowhere and blew it up, lifting her higher. She quickly tied it on to herself with a piece of string. “Yup! It’s not going to happen!” Pinkie agreed.

“But what if it does?” Rainbow Dash grabbed Pinkie Pie incredulously. “They’d be all over each other, kissing and stuff!” She couldn’t help but imagine Rarity and Applejack holding one another, tongue wrestling. “And if they kiss, they’ll grope! And if they grope, they’ll fondle! And if they fondle…” She imagined them on their backs, scissoring, Rarity using her Unicorn magic to manipulate toys to aid their pleasure. “They’ll have sex!” Rainbow Dash declared.

“This sounds really exciting!” Pinkie exclaimed, eyes wide with intrigue. “Then what happens?”

Rainbow Dash was taken aback. “After sex?” She shook her head. “Then Applejack won’t be mine anymore! She’ll be Rarity’s!” The pegasus swooped down to the ground and collapsed, sobbing into her hooves. “My life is ruined!”

“Wait, what?” Pinkie questioned, releasing the balloons that held her up. She fell to the ground with a squeak. “Why wouldn’t Applejack be yours anymore?”

“Because!” Rainbow Dash cried, looking up. “Every time we get together she’ll be thinking about her instead of me!”

Pinkie Pie frowned. “No! That’s totally wrong!” she yelped. “You’ve been with Applejack for one year, seven months, and ten days! She’s completely in love with you, and you’re in love with her!”

Rainbow Dash looked up, discreetly wiping tears away. “So?”

Pinkie Pie rolled her eyes. “So, she’s still gonna be yours! She’ll always be yours! One night with another pony isn't going to take that away.” Her face turned into one of thoughtfulness. “Besides, Rarity already knows, right?”

It was true. The invitations to the party had helped Rainbow Dash convince Applejack that they should tell all their friends so there wouldn’t be any surprises. Pinkie Pie had known since the last party and since she was Rainbow Dash’s main confidant, she already knew the others would be told.

Fluttershy didn’t mind at all, and understood their need to be discreet, especially around the rest of the Apple family. Rarity wasn’t surprised and even claimed to have seen the signs of their relationship. Twilight Sparkle was the hardest to predict, but she welcomed their coming out to her, and suggested making rules for each other so nopony’s feelings got hurt during her party.

“Yeah, we told all of our friends. We even made rules: no kissing, no licking another’s … thing … and no strap ons.”

“Don't worry, Rainbow Dash! Applejack will definitely follow those rules. She’s really dependable! She's gonna follow the rules, and that means she'll be thinking about you the entire time!”

Rainbow Dash sat up and looked at Pinkie Pie. "You really think so?"

She shook her head. "I don't just think so; I know so!" she said confidently.

Rainbow Dash sniffed away the rest of her sadness, taking in Pinkie's words. They hadn’t been apart for more than an hour and Rainbow Dash couldn’t take her mind off Applejack. It was reasonable that she’d do the same for her. She remembered the times she’d spent with Applejack, like their secret date in the Everfree Forest where they dared each other to do things ranging from scary to sexy. Applejack was so scared she hid in a tree and Rainbow Dash flew in to calm her down, with gentle kisses and hugs.

"Yeah, you're right, Applejack is mine, no matter what. She would never break the rules." Rainbow Dash nodded, convinced. "And I'm okay with her thinking of me the whole time. I'm a totally awesome pony to think about!"

"Especially for Applejack!" Pinkie agreed.

Rainbow Dash smiled genuinely. "Thanks, Pinkie. That really helped."

"No problemo!"

"Um, could you not tell the others? I don't want our other friends to know how jealous I am."

"Okie dokie loki!"

“Promise?”

Pinkie Pie pantomimed zipping her lips, locking them with a key, burying the key in a hole, building a house on top of the hole, and then moving into the house she built on top of the hole, but to Rainbow it looked like she was doing some kind of special Pinkie dance.

“I’ll take that as a yes?” Rainbow asked questioningly.

“I Pinkie promise!” Pinkie confirmed, putting a hoof in her eye.

The two mares stared at each other for a moment.

"You're really pretty." Pinkie Pie exclaimed suddenly.

“I'm what?" Rainbow blushed for a moment, caught off guard by the compliment. "You… you really think I’m pretty?” Rainbow asked with a hint of sarcasm.

“Pretty as a prism!”

Rainbow smiled, “you are a silly pony.”

“I try!” Pinkie Pie said, doing a cart wheel. When she was finished, she bounded back. “Wanna hear a secret?”

Rainbow Dash nodded. “Sure, what’s your secret?”

Pinkie Pie looked around the empty room to make sure no one else could hear. “I really like balloons.”

Rainbow began to laugh. “But Pinkie, everypony knows that! It’s your Cutie Mark!”

Pinkie Pie shook her head. She expected this response, but still grimaced. “No, I really really REALLY like balloons.”

Rainbow stopped laughing, trying to understand.

“And not just like,” Pinkie continued, “I like like balloons.”

"Wait, you mean to tell me that you have a balloon fetish?" Pinkie nodded fervently. "Oh my gosh, that's so ridiculous!" Rainbow Dash resumed her laughter.

"Promise you won't tell anyone!"' Pinkie demanded.

"I promise! I promise!" Rainbow Dash calmed. "How does that work, with the balloons? Do you rub them against your junk? Wouldn’t they pop?" Rainbow shuttered, thinking about a balloon popping between her thighs, the latex suddenly collapsing and slapping her skin.

“Well, I do do that, and sometimes they pop, but there’s lots of other things you can do with balloons!” Pinkie pulled an orange balloon from somewhere and stretched it between her hooves. She blew it up.

This one was long and thin, and typically used to make shapes. With a few twists, she turned it into a simple balloon pony. “You can make a lot of things with balloons!”

“You can make a lot of things. I don’t think I’ve ever blown one up without popping it. They’re just so hard to tie off …”

“I’ll make you something!” Pinkie offered, taking out three more yellow balloons, two of which landed in her hair. “What do you like?”

“Um…” Rainbow Dash hesitated. It was weird thinking that this was Pinkie’s fetish, but then, Pinkie had made her tons of balloon presents, and it wasn’t weird before. “How about a pith helmet?”

“Okay!” Pinkie inflated and twisted the balloons, each motion making that characteristic rubbery balloon sound. Rainbow looked on in her usual awe as Pinkie made an oversized balloon pith helmet, just like Daring Do’s. Then she put it on Rainbow’s head and grinned.

Rainbow’s eyes moved from the helmet on her head to Pinkie Pie. “And… that turns you on?” she asked, still confused.

“Well, it doesn’t not turn me on,” Pinkie Pie responded, shrugging her shoulders. “But there’s more to balloons than balloon animals and balloon hats!” Pinkie began to jump around demonstrating all of the different ways balloons could be as she sang along.

Each has a color, like lime, or pink, or teal,
Each has a shimmer, that makes them look surreal,

They come in tubes, short, or long,
They are shaped, square, or oblong,

The way they float,
The way they bloat,
They all look good to me!

Rub them and our fur stands on end,
Twist them and we can make them bend,

The breaths they take,
The squeaks they make,
They sound like music to me!

Some are so big we fit inside,
Some are so small they fit inside,

Superb and round,
With fun abound,
They’re all so fun for me!

Pinkie Pie stood tall on her hind legs, forelegs outstretched with three pear-shaped balloons of red, pink, and yellow in each hoof.

Rainbow Dash stared incredulously, “I don’t know what to say,” she said, taking off her balloon hat.

The vulnerability of telling a close friend her fetish was beginning to take its toll. Pinkie Pie hadn’t told any of her friends about it before, and she was very worried how they might react. She so rarely let any pony see who she was behind her ever-smiling face, but Rainbow Dash had during a mental breakdown involving a bucket of turnips, a pile of rocks, a sack of flour, and a ball of lint attending an after birthday party for a certain alligator. Her continued loyalty to their friendship, despite seeing this, made her ideal to come out to, but Pinkie still feared the judgment.

Pinkie’s face turned to a sort of exasperated worry as she exclaimed, “say that you understand what it’s like to have a fetish that nopony else understands, and you’ll be my friend no matter what!!!”

“Woah, woah, woah!” Rainbow put up her hooves defensively. “I understand what it’s like to have a fetish…” she said instinctively, but stopped. It wasn’t true: she didn’t have a fetish. Her biggest secret was that she was into mares, but her friends already knew that, and it seemed tame next to Pinkie’s balloon fetish. She wanted to lie, for the sake of Pinkie’s self-esteem, but Applejack had been encouraging her to be more truthful, especially when she was pressured not to. “Actually, no, I don’t have any fetishes," she corrected herself, "but I promise I’ll be your friend, no matter what sort of weird, crazy fetishes you have.”

Pinkie Pie’s face turned thoughtful for a moment before it returned to its normal smile. “Works for me!” she declared. “Wanna see what it’s like to be inside a balloon?”

“I..inside?” Rainbow imagined being shrunk down to the size of a Breezie and then placed inside a balloon while a gigantic Pinkie Pie laughed over her. She shuttered. “I'm not sure. How does it work?”

Pinkie ran to her present and opened it, pulling out a very large, uninflated cream colored circular balloon. “It’s just a big balloon! And then you get inside it.”

Rainbow Dash sighed with relief that it didn't involve getting shrunk, but was still unsure about it.

Pinkie Pie pulled a wooden billow from the box, stuck it into the balloon, and started hopping on it.

As the balloon inflated, Rainbow Dash tried hard to put herself in Pinkie Pie’s mind. She listened woosh of air being forced inside and the simultaneous stretch of the material. She stared at the semi-transparent surface and the splash of light that it reflected. She smelled its powdery, rubbery scent. All of it did nothing for her, but she imagined this was hot stuff to Pinkie. “I don’t want to get inside it," she said carefully, "but I’ll watch you do it.”

“Okay!” Pinkie Pie nodded, happily bouncing on the billow. Her hair shook with each bound, smiling wide with happiness. Rainbow Dash felt giddy from Pinkie's infectious spirit. She wasn’t sure what to expect, but she knew Pinkie Pie was going to enjoy every moment of it.

Once the balloon was nearly four times her size, Pinkie Pie pulled it off the billow. It was now transparent and swayed with every move. She stuck her head into the opening, her pink hair poofing out like normal on the other side. Next her forelegs pushed through, letting a little air escape until the rubber collapsed on her waist, sealing her half way. Pushing the opening down her body, she stepped inside, taking care to keep her tail from getting caught. She clamped the hole shut with her hooves. "Tada!" she called, the balloon now only twice her size.

"Wow" Rainbow Dash remarked, looking at her friend in the bubble. It reminded her of a Daring Do novel where Ahuizotl captured Do in a small magical forcefield. She enjoyed that scene a lot, as she often wondered what she would do with an attractive mare trapped in a forcefield. "Can you breathe in there?"

"There's plenty of room to breathe!" Pinkie Pie explained, her voice distorted by the balloon. "But it gets hot really fast. I like to keep my head on the outside." She started jumping, moving the opening a few inches with each leap. When it was in the right place, she popped her head out and exhaled loudly. "Much better!"

"You're really enjoying yourself in there, aren't you?"

"Yes I am!"

“Now what do you do?”

“Now I bounce around like a ball!” Pinkie pushed into the ground with all four legs at once, springing herself and the balloon forward. “It's so much fun to bounce!" she said as she hopped around Rainbow Dash. The balloon jiggled each time she landed, slowly deflating.

"I guess so," Rainbow Dash said uncertainly. Then a mischievous look flashed across her face, and when Pinkie Pie bounced in front of her, she took off, her forelegs out, hoping to send Pinkie Pie flying across the room like she was a giant beach ball. When she connected, the balloon deformed, expanding in all other directions, and then rebounded, throwing her backward. "Aaah!" She cried out.

“Silly Rainbow!” Pinkie laughed, continuing to bounce around her. “You can’t just hit a pony in a balloon!” She jumped again, but this one didn’t carry her as far. “Uh-oh!”

The balloon had deflated so much that it stretched tightly over Pinkie Pie, restricting her leg movement. It continued to compress around her, forcing her into a kneeling position. Her fur was pressed against the edge of the balloon, and her matted mess of a tail was held to her back by the translucent stretched material. Rainbow Dash stood over her and chuckled.

“Hey, not funny!” Pinkie Pie pouted playfully, as the balloon forced her to tuck her legs under her.

“Pinkie, you don’t have to bow before me!” Rainbow Dash chided.

“I’m not bowing before you! I’m trapped in a balloon!” Pinkie Pie struggled to move, managing to inch worm a few times before falling over on to her side.

Rainbow laughed some more. “Do… do you need help?” she asked earnestly.

“I’m fine!” Pinkie insisted. “I just need to wiggle my way out.” She began to kick against the balloon, which inched down her neck.

Though she hated to admit it, Rainbow Dash was having a lot of fun watching her friend struggle. She liked how the tight balloon accented her pink body, showing off each curve on her legs. She grinned as Pinkie Pie wiggled onto her back, giving a nice view of her smooth round bottom, dipping slightly with the outline of her marehood. Best of all were Pinkie Pie's grunts of pleasure and frustration coupled with her look of bliss. Rainbow Dash smiled coyly before darting towards Pinkie Pie again, this time rubbing her with her hooves, tickling her.

“He-hey!” Pinkie Pie laughed, shaking from the sensation. She instinctively kicked harder, though it didn't slow her tickler.

Rainbow Dash was relentless, and expanded her range to include some of Pinkie's more intimate regions. She brushed up against her thighs and rubbed her rump. Though she was use to the more muscular body of Applejack, she approved of Pinkie Pie's well-toned legs, no doubt a by-product of her weekly dance parties.

Rainbow Dash was very turned on, and Pinkie Pie was clearly ready for more. She held her breath as she took it to the next level. Her movements slowed to gentle caresses, and laughter morphed into moans of pleasure. The Pegasus pushed Pinkie’s hind legs up and forward, giving her access to her covered marehood. She then roughly ground her hoof into the pink pony’s pussy, which was now moistened with her excitement.

Pinkie’s mouth fell open and her cheeks turned red. Her eyes lost focus and her body fought against the balloon for more. Between the feeling of the latex against her fur, coming out as a balloon fetishist to her friend, and the marvelous sensation in her nethers, she felt exceptionally vulnerable and yet also fulfilled.

Lost in the moment, Pinkie stretched out her leg and pressed against the balloon, when suddenly the stretched material gave way with a loud snap. Rainbow Dash recoiled in surprise as the rubber whipped by her hoof, revealing a bed of soft pink fur beneath.

"I guess that happens sometimes?" Rainbow Dash asked awkwardly.

"Sometimes," Pinkie replied evenly, peeling the broken balloon off over her head, “but it’s just a balloon.” She shifted onto her back and spread her legs, her forelegs slack at the wrists. "You don't have to stop," she cooed.

Rainbow Dash suddenly felt like she was somehow cheating on Applejack, like not having the balloon between them was against the rules. But it wasn’t, she reminded herself. She hadn’t kissed, licked, or used a dildo, and she didn’t want to either. She took a deep breath and let it out, trying to relax.

She looked Pinkie Pie up and down, taking in all the beauty the silly little pony had to offer. Pinkie was practically steaming from the hot air that was trapped inside the balloon, her sexual scent permeating the room. With her legs wide and body in such a willing, wanting position, and the look of desire on her face, Rainbow Dash couldn’t help but give in to lust. She wanted to make her squirm with pleasure.

She stepped forward, straddling Pinkie’s right leg, and shoved her hoof against Pinkie’s crotch, grunting as she did. Pinkie Pie, reacted accordingly, arching her back and thrusting into her. Rainbow Dash rubbed her hard, directly on her clit. The intensity shot through Pinkie, causing her to tense her body and grit her teeth as she moaned softly. Rainbow Dash grinned at the reaction.

Then Rainbow Dash pressed her own sex into Pinkie’s leg, leaning forward for a better position. She began to rock back and forth, giving herself a pleasant thrill while grinding her hoof against her partner.

Pinkie Pie was in heaven. Her high-speed mind, normally crowded with all sorts of random thoughts, were all focused squarely on the colorful Rainbow Dash above her, and the sensation she was being given. Her body welcomed the overwhelming sensation, and she shook from the intense pleasure. Closing her eyes, she lay back and let Rainbow do whatever she pleased.

Rainbow Dash continued thrusting, pushing into the ground for more force. As her excitement grew, her wings began to flutter, making her lighter, and giving herself better control of her own enjoyment. She watched as Pinkie Pie lost control and gave into the feeling.

“Yes!” Pinkie cried softly, as she flailed her forearms. She tried to get them back under control by biting the edge of her hoof, her eyes tightly shut. “Yea!” she gasped again. Her muscles tensed; she was ready to explode with just a little more.

Rainbow Dash was certainly enjoying herself, but there was no way she was going to catch up to Pinkie Pie. So she kept it up, thrusting and rubbing, enjoying it immensely, as Pinkie Pie went from yelps to a long muted squeal. Eventually Pinkie let it all go, and she came with a scream that echoed off the stone walls.

Pinkie Pie panted heavily with her tongue hanging out. Rainbow Dash slowed her hoof down enough for Pinkie Pie to catch her breath, but didn't stop, focusing instead on her own pleasure. Leg-riding wasn't an ideal position, but she didn't want to change just yet. The firm pressure against her lips and the warm friction of movement were thoroughly enjoyable. Plus, each time she flicked her wrist, Pinkie Pie would shudder beneath her.

At last Rainbow Dash's pleasure peaked. She sighed happily, feeling her inner walls squeeze. It wasn't a full climax, but still a wonderful feeling that dampened Pinkie's fur. She slumped back, releasing her partner.

They both relaxed quietly, listening to each other's pants resonate in the vast room. Slowly, Pinkie Pie sat up and looked at the cerulean Pegasus. "That was really REALLY fun!" she smiled, her energy rising as her words became faster. "I never knew balloon sex would be so amazing! I mean, I always thought it would be amazing, well, technically it's always been amazing, but that was just with myself before. But really, balloon sex with you was absolutely amazing!!!" Pinkie Pie was now standing and, realizing this, she quickly sat down. “How was it for you?"

"It was great," Rainbow Dash nodded. "I'm really glad you enjoyed yourself."

Pinkie Pie recognized the lack of enthusiasm in her voice. She tightened her lips and pondered for a moment. Then suddenly her face popped into a look of concern. "Oh my gosh, you didn't cum!"

"No, it's fine! It's really fine!" Rainbow Dash held up a hoof. "Seeing you like that was lots of fun, and I got some good stuff too!"

"No no no, you have to cum! What's the point the story if you don't cum?"

"What's the point of the wha-aa?!" Pinkie Pie pounced, throwing Rainbow Dash onto her back. In a flash, her head was between Rainbow's legs, her mouth caressing the athlete's wet yet unsated pussy.

"You don't have to do that!" Rainbow Dash cried, pushing lightly on Pinkie's head. "I'm... I'm... fine..." her voice trailed off as Pinkie's tongue entered into her, the soft delightful experience overpowerIng her mind. Her mouth hung open as her breaths shortened once again.

Pinkie Pie bobbed up and down, giving equal attention to all parts of Rainbow Dash's lady bits. She pushed rhythmically, her nose tapping against the clitoris and her lips outlining the labia. Her tongue, which was rather long by pony standards, stroked between the folds, tasting the happy mare's salty flavor. Rainbow Dash let out a loud moan and a splash of wetness squirted out, landing on Pinkie Pie's face and dribbled down her chin. She could tell that her actions were thoroughly appreciated.

The pleasure seemed to flow from Pinkie Pie and radiate through Rainbow Dash’s body, making her skin tingle. She spasmed a dozen times more before she felt the big one on the horizon. Her legs bent rigidly as she readied herself, Pinkie Pie doggedly licking all the while. “Oh boy, here it comes!” Rainbow Dash cried, burying her hooves into Pinkie’s hair.

Rainbow Dash howled as she came, for real this time. She squeezed Pinkie’s head between her thighs and pushed it tight against herself with her hooves so she wouldn’t escape. Pinkie sped up her tongue, nearly overwhelming Rainbow with pleasure, though she bared through it.

Rainbow Dash’s grip on Pinkie loosened and the pink pony withdrew, both breathing heavily. Rainbow’s mouth was agape with exhaustive afterglow, while Pinkie grinned happily, a line of off-white cum on her face. She looked down at it and, with her long tongue, licked it up like it was leftover icing from a cupcake.

“Now how was it for you?” Pinkie Pie asked, nearly bouncing with glee.

“Great!” Rainbow Dash said earnestly. “I mean, really great Pinkie. That was exactly what I needed.” She rolled onto her side and clumsily stood up, only to find her back legs were so shaky she had to sit. “Yeah, that was pretty amazing.”

“Super-rific!” Pinkie cheered. “Ready for bed?”

Rainbow Dash blinked and exhaustion hit her like the Friendship Express. “Bed sounds really good…” she said lazily. Pinkie zipped to their bags and back several times, putting out Rainbow Dash’s purple sleeping bag with her own pink one next to it, each furnished with their respective pillows.

Rainbow Dash flopped down onto her bed. She contemplated finding her ear plugs for a better night’s sleep, but decided it wasn’t worth the trouble of getting up. She rolled over and saw Pinkie Pie already lying down and tucked into her bag.

“Thanks, Pinkie, for everything.”

“Thank you! And you’re welcome! You know, they should have a phrase for that. Like, Thank-you’re-welcome!”

Rainbow nodded and smiled. “Yeah, you’re right, Pinkie. Good night!”

“Good night!”
