Rainbow Dash didn’t know why she did what she did. She knew it was crazy, given how poison joke made her fly weird. So it was no surprise that she asked Zecora for the antidote first as a just in case. So, with a plan to treat her marefriend, Applejack, she fly uncontrollably to her home, and crash right into her as she was bucking apples.

Applejack was minding my own business, when all of a sudden Rainbow Dash came crashing out of the sky! The buckets of apples she'd been collecting were sent flying, and the pair of them rolled in a heap until we settled in a pile a few feet away.
"Rainbow Dash! What are you doing?!? I've told you a million times, don't go practising your crazy flying routines in these orchards!" she exclaimed, staring at her with wide eyes.

"Sorry, Applejack," Rainbow replied, getting up before offering a hoof. "I don't know what happened, but I just, lost control." she had to lie to her, given she knew why it happened. And what she planned to do with her. "But now I’m here, how about we go inside? After all, isn't it getting late?"

Applejack could do little more than grunt and roll my eyes, taking her hoof and helping myself up. "Eugh, it's alright. She was almost done anyhow. It is getting pretty late, you may as well come in, and I can't imagine your wings are doing too good after a crash like that..." Making sure she was okay, she lead the way back to the farm, and couldn't help smile a little. Rainbow Dash and she had always gotten on well, and something told her that she didn't crash into her by accident.
"Hey...what do you say we settle down in the barn, hmm? There's not really a space for you in the house, and the hay is plenty comfy. I might even join you, if you ask nicely."

Applejack was falling for Rainbow’s plan. "That sounds like a great idea, and would love you to join me. You may want to warn the others I'm here though. Don't want me going hungry either." she chuckled, trying to make it seem like a joke, before following on hoof. It was...a bit more difficult, but eventually she was able to make it to the barn.

"Hmm, yeah I guess you're right. You're looking a little rough actually, so why don't I go on ahead to let them know, and I'll meet you inside, okay?" she suggested, trotting ahead, and hollering for my family, to let them know what the plan was. She let them know she was just going to spend a little while with Rainbow, to make sure she was okay, and if they could leave a pie out for her to eat later it'd be much appreciated. Once sorted, she headed to the barn, to see if she was already inside.

With Applejack distracted with her family, Rainbow tried once again to fly, crashing into the barn with a coil of rope falling on top of her. She knew she shouldn't've flown, but she couldn't help herself. But, she stayed where she was, given she was exactly where she wanted to be. An excuse forming in her mind, she lay in wait.

Just as Applejack was about to enter, she head an almighty crash! Concerning, she ran inside, and just stared at the sight before her.
"...well then, something tells her that you did a little more than hit your head this morning Rainbow Dash." she said, looking at her, unimpressed as she came closer. "Did you by any chance eat a little Poison Joke or something? Honestly, you never fly this bad, even when you're doing it on purpose! Come on, this is just getting silly, and it's far too late to grab some antidote from Zecora..."

Rainbow Dash smiled, her excuse leaving her. "I...may have flown through some on accident. And I made sure to bring an antidote with me. But, I would also hope you'd want to do things with me given I can't fly?"

Applejack couldn't help but let out a laugh, and grinned as she came closer, scooping up the rope entangling Rainbow Dash with her hooves and smirking. "Hmm, well, even with an antidote you haven't taken it so...I think we better make sure you stay grounded~"
Carefully, she started to tie her up, making sure to give her enough room to at least move around a little. Clipping her wings specifically behind her back, she teased out a kiss as she lay on top of her body, lying there for a moment as she enjoyed her body heat.
"You flew through Poison Joke, and your first thought was to come to me? How sweet..." she commented, beaming.

Staying still, which was easier said than done, Rainbow lay there as Applejack tied her up, although she was a little surprised when there was some wiggle room. Although, the kiss made up for it as she lay on top of her. "Well, who else would I fly to? After all, it means you have full reign over me tonight, right?"

Applejack snickered at her comment, kissing her harder as she pulled on the ropes, making sure her bonds were nice and taut as her lower hooves teased open her legs, and she let her tail brush against the exposed crotch.
"Damn right I do, you're going to be neighing so loud you'll be heard all over Ponyville~" she cooed, sliding her tongue inside her mouth and panting slightly, cradling her face in her hooves as she started to get into the mood.

Rainbow shivered slightly as her privates got brushed, and feeling the ropes tighten. She didn't get a chance to respond before she felt Applejack's tongue start to play with hers as they kissed and made out. Applejack dictated where things went, and who was she to stop her tonight, after all they had done?
At the first opportunity she got, she replied to the remark. "Well, why don't you put your bits where your mouth is?" she taunted, knowing the last piece of the puzzle was in place for what she had planned.

Applejack was almost too lost in the kiss to hear what Rainbow Dash was saying, and only just caught the end of it. Stealing one last kiss, she slowly lifted herself off of her body, and brought herself lower, pulling Rainbow Dash’s lower hooves as far apart as possible, and gently pressing her lips against the folds.
"Oh, don't you worry, we've got all night. You'll be getting plenty of this..." she teased, spitting her tongue out, and starting to eat her out. As she licked, she tasted something...odd, but decided to ignore it, too aroused to care as she dived deeper into her with my tongue.

Soft moans erupted from Rainbow’s mouth as Applejack tasted her nether region, a bit confused why she didn't stop, or at least ask why it tasted odd. Although the more she licked, the more she moaned, and the more she forgot about it all. She had forgotten what the plan was, but that didn't matter anymore, since she was enjoying tonight. As she continued, however, she noticed her licks not penetrate as far as they were. And realised what she had planned coming to fruition. "Hey, Applejack," she called, soon enough able to regain her composure, "Don't want to be that pony, but I get the feeling you're feeling a bit short in all of this."

Just as Applejack was starting to build up a rhythm, a small...leaf seemed to land on her tongue, and she awkwardly swallowed it, immediately coughing and spluttering in confusion.
"What in the...?" she asked, looking up at Rainbow Dash with concern. However, as soon as she did her eyes grew huge. "Oh you cheeky devil!"
She was already easily half her height, having licked up a good mouthful of Poison Joke, and the bit she'd just swallowed was steadily speeding up the process. She couldn't even run, she could only stare at Rainbow Dash as she slowly grew before my very eyes.
"Y-you coulda just asked me ya know!" she finally shouted, Rainbow’s pussy soon becoming the only part of her she could see clearly as she dwindled down and down.

It was hard for Rainbow to hold back a small chuckle as she watched Applejack shrink. But, she did look cute all shrunk like that. "I would have," she responded, now looking at a tiny Applejack, "but I didn't know what you would have said. It seemed such a weird request, after all." she began to rock herself forward, hoping to roll forward, and squish Applejack between her legs.

"Right, and tying you up like a Christmas present was so normal by comparison!" Applejack pointed out, still simply staring as she shrink down, soon small enough to fit in Rainbow Dash's mouth...among other places. She noticed the way she's rocking back and forth, and gulp with concern, slowly backing away.
"Hey umm, you sit still, okay? I'm fragile at this size, you wouldn't want to accidentally squash me!" she try to point out, but Applejack was clearly too busy staring at her to actually escape.

"Don't worry, I know what I’m doing," Rainbow Dash reassured, lining Applejack up so she wouldn't get squashed. "I wouldn't want to hurt you, ok?" Eventually, she was able to roll forward, her tiny friend ending up into her crotch, as planned.

"Riiiight, if you say so..." Applejack said, not so sure about this. However, any time she had to doubt had already run out, as she could do little more than gasp as Rainbow Dash came crashing down on top of her, her entire body soon completely swallowed up by the slick opening. She panicked, flailing around inside her, and in no time her fur was being generously coated in her own saliva, from just a few moments ago. The smell of the Poison Joke was still pretty strong as well, and she shivered as she worried about what might happen if she stayed in her too long.
"W-woah, you're letting me out of here, right Rainbow?!" she asked, being slowly pulled deeper inside her.

"Of course!" Rainbow Dash replied, rolling back as to feel more comfortable. "I didn't want to keep you there forever after all. But, I thought this would be a fun experience for us both. Plus, I doubt you can shrink any more than you are already." she moaned slightly as Applejack went deeper inside her, happy that it felt as good as she thought.

"Heh, well, that's reassuring at least! I think I might have a little trouble getting here without your help after all..." Applejack told her, lurching as the entire chamber around her shifted once more. Her face smushed against the walls, covering it in arousal. Panting slightly from the humidity, she spat her tongue out, and eagerly lapped at the flesh all around her, spreading out her body as she started to get comfortable.
"A-although, I don't mind...staying here a bit longer~" she added, sighing as she started to embrace her new situation.

Moaning more from her tonguework, Rainbow Dash now began work on the ropes Applejack had tied her with. "What about another time too then? This is fun!" While she was a bit jealous she wouldn't be able to repay the favour, she thought of how best to repay her.

Starting to get more playful, Applejack teased at Rainbow Dash's innards, moaning softly as she slowly but surely began to get completely drenched in sweat and pre-cum.
"S-sure, any time... I'd love to do this more, whenever you want..." she said between pants, now moving around quite vigorously, clearly far too aroused to even care about what she was doing, this was just far too much fun!

Rainbow’s moans grew louder as Applejack moved more erratically, unable to speak as pre leaked out, and her limit approached. She couldn't speak, let alone breathe much, outside of the short gasps between moans. "S...sounds, like a, plan," she panted, the rope no longer around her, although she didn't notice.

Applejack started to crawl ever deeper the louder Rainbow dash moaned, grinning as her world vibrated with more and more energy the further she pleasured her. She slipped up every so often, but soon enough she reached the end of the tunnel...and bit down hard on the flesh before her.
'This is what you get for feeding me Poison Joke, you trickster~' she thought to herself, shutting her eyes tight in preparation for the flood.

If Applejack's crawling wasn't enough to set Rainbow Dash off, her biting down at the end of her cave did. Without warning, a flood of cum came splurging out, ejecting both Applejack and the remaining Poison Joke from inside her. Panting hard, she looked back down at the mess that they had just made, and regained some control over her breathing before talking again. "So," she began, "you had fun too, right?"

Applejack was forced out of Rainbow Dash in a matter of seconds, sliding across the floor of the barn as nothing more than a cum drenched mess, gazing upwards weakly at her body, and grinning like an idiot.
"Okay...that...was incredible..." she panted, still struggling to get her breath back as she nodded weakly in agreement. "We need to do that again. Like, as soon as possible. Y-you need to play with me more too, I can't just eat ya out from inside ya~"

"Of course we do!" Rainbow Dash replied, slowly getting up and onto her hooves, and walked over to Applejack. "And I wouldn't want to always be played with. I want to play with you too!" By this point, exhaustion overtook her, as she collapsed next to her friend. "I guess it can wait until tomorrow, right?"

Applejack looked up, mortified as Rainbow Dash suddenly starts to fall towards her. She leapt out of the way, her head hitting the ground nearby. Breathing a sigh of relief, she trotted over, and gently kissed her full on the lips, still mostly weighed down by her fluids.
"Well, I’m more than happy to play with you, all tied up for my pleasure~" she cooed, smiling weakly as she stood before her face. "But umm...any chance you could grow me back to normal? Or, ya know, clean me up at least, hehe."

Smiling weakly, Rainbow tried her best to return the kiss, only to find she didn't even have the energy for that. "The antidote is in my saddle bag, but we both know I’m too weak to get it right now." she rolled onto her back, staring at Applejack as she stood there, an idea coming to mind. "You want me to clean you, right? But if you go back inside, there's no point me cleaning you up, as you'll just get messier."

Applejack smiled, and watched on with awe as Rainbow Dash rolled onto her back, shaking the ground from her perspective. Tracking fluids, she climbed up her fur, settling at the back of her neck, and lying there as she gazed into her eyes.
"H-hey now! Come on, the least you could do is lick me clean, I can't go around like this for the rest of the night... Even if I did go...back there...I wouldn't mind being a smidge drier, ya know?" she pointed out, smirking. "Come on, you know you wanna taste~"

Applejack knows Rainbow Dash well. "Ok then," she gave in, "I'll give you a lick before you return." She goes to roll before remembering Applejack climbed on top, so instead she opened her maw, letting her tongue lay out like a carpet. "But you have to walk on in, if you want a lick~"

As Rainbow Dash opened her mouth, Applejack couldn't help but shudder, the sight of her maw opening out before her, and her throat looming just beyond, which she could slide down all too easily.
"S-sure, why not? I’m not afraid of a little lickin'..." she say, tentatively stepping forward. Reaching her tongue, she placed her hooves on it, but the combination of slippery surfaces meant she lost her footing almost immediately, and let out a panicked scream as she slid across her tongue, soon falling straight inside her mouth...

Being careful, Rainbow moved her tongue back into her mouth, trying to prevent Applejack from falling into her throat. Making sure she hadn't, she lifted her up a bit, licking her all over. The taste of cum mixed with her fur was great, as she kept licking, tasting as much of her as she could.

Applejack gasped as the tongue underneath her caught her, just moments before she would have ended up inside Rainbow Dash's cavernous mouth. The instant she slammed her against the roof of her mouth, she moaned loudly, Rainbow’s tongue rubbing all over her body and striking her pussy with full force. Her tastebuds were large enough at her size to grind all over her body, and she quickly started humping against it as she was rolled around, barely able to contain herself.
"Sorry Dash, you've got another lil spillage to clean up... Ahhh!" she cried out, arching her back as she came all over the squishy surface she was lying against.

The taste of their cum mixing together was blissful. Rainbow Dash didn't even care that Applejack spilled herself, because it made things better. Once she had finished up, she pushed the now cleaned Applejack to her teeth, and out of her maw, gulping down the rest of the mixture once she was safe. "You ready now?" she asked, eager to return Applejack to her crotch.

Absolutely shattered, Applejack’s body went limp as Rainbow Dash elegantly pushed her around, settling between her teeth easily as she swallowed, gasping out in the afterglow of what had just happened.
"Oh, you could put me up your rear and I wouldn't care, that was heaven. Go ahead big girl, I’m ready..." she told her, grinning like an idiot as she weakly kissed her lower lip while leaning over it.

Picking up her friend in a hoof, Rainbow Dash moved her down her body, a cruel plan forming. "Thanks for the idea, but not today. Another time, for sure!" With some force, she dropped Applejack onto her privates, and with one hoof she pushed her back in, before getting comfy in the barn. "I hope you have a good night, Applejack," she cooed softly, before letting sleep find her.

"Hehe, hey it was just a suggestion~" Applejack said, smiling as she was slowly moved over her privates. She stared for a second, realising the drop below, but before she could say something she was dropped.
"Why yooooou!" she yelled, spinning through the air before slamming inside, her head barely poking out from between the folds. A hoof descended quickly however, and she was sucked inside in moments. She rolled her eyes, soon deep within her pussy once more, and shuffled a little as she settled, getting into a good position inside her.
"Goodnight Rainbow Dash, see you in the morning..." she yawned, closing my eyes and curling up into a ball within her.

Author's Note

So yeah, this was the initial roleplay we did. The way we wrote it made it easy to convert to a story, even though it took about half an hour to chenge the tense.
