Applejack tipped ‘Bill’ down over her face as she stepped out of the house, glaring at the conspicuous light in the barn window. Her entire family was inside right now, hiding from the driving rain that was pelting Sweet Apple Acres, and that meant that whoever was in the barn didn’t belong there.

A little rain wasn’t going to keep AJ from going out there and bucking them square in the teeth if they were trying to make off with anything that wasn’t theirs.

She took off at a gallop, her hat shielding her eyes from the worst of the unexpected storm. She kicked up cold, muddy water that splashed along her barrel and legs as she ran, the bright red barn drawing closer with every step.

Rares’d tan mah hide if’n Ah paid ‘er a visit like this. Applejack chucked mentally. Maybe after Ah take care o’ this varmint Ah should do just that, Ah could do with a good tannin’….

As she rounded the side of the barn, she thought she heard singing. A rich baritone voice too, just a mite higher than Mac’s singing voice.

“Slide, ride, glide the Michigan! Stomp, romp, pomp the Michigan! Jump, clump, pump the Michigan nag, that lovin' naaaaaaaaaag!”

As the singing drew to a close, Rainbow Dash came running out of the barn, her eyes wide as dinner plates, panting like she’d just run the whole of the Everfree Forest.

“AJ, you have got to come see this!” She gasped, grabbing the perplexed earth pony and dragging her into the barn, where a frog was sitting on the ground.

“It sings! It dances!” Rainbow told her, pointing at the frog. “It was just singing now! You heard it!”

Applejack stared at the green frog, which stared back at her placidly.

“Encore?” She shrugged.

“Rrrrribbit,” the frog replied.

“Really, it sings!” Rainbow insisted. “This thing landed on my back when I was trying to knock this storm down from a hurricane to something that wouldn’t trash Ponyville, and it was dancing the whole dang time! It just stopped now!”

Applejack looked at Rainbow, really looked at her. Breathing hard. Soaking wet. Wings flared out excitedly. Mane draped over her face just so. A good look for her, really. Yeah, it was pretty clear what had happened.

“S’all right, RD, y’all can tell him to come on out. Y’all got a little frisky with one o’ the Weather Team after fightin’ that storm, Ah’m a big girl, Ah understand. ‘Sides,” Applejack winked, “not against the rules as long as y’all are willin’ to share. Who was it, Thunderlane? Didn’t think he could sing like that.”

Rainbow’s jaw dropped.

“What?!? You think… but the frog… gah!” Rainbow threw up her hooves and flew off to a bale of hay. Applejack shook her head, nudging the frog with a hoof to send him hopping on out into the rain.

“Y’know, Ah actually think it’s kinda cute y’went to so much trouble to try and hide ‘im,” Applejack smiled, trotting over to the hay and sitting down next to her soaked marefriend. “Ah ain’t mad, sugarcube.” She turned her head and kissed Rainbow on the cheek, only to be shoved away by the sulking pegasus.

“Yeesh, fine, never mind,” Applejack shrugged with a spreading frown of her own. “Y’know, Ah actually thought somepony was tryin’ to steal some apples ‘r somethin’ when Ah came out here. Pleasantly surprised to see you instead, but if y’all’re in a mood like this, Ah don’t know anymore.”

“I wasn’t fooling around with anypony,” Rainbow muttered, crossing her forelegs. “Geeze, Boss, you know I wouldn’t try hiding that from you, or from Rarity! Hay, I was with her all last night, you really think I’d be in the mood for some stallion to be singing while he was rutting me, of all things? I mean, sure, if he was singing my praises maybe, but I’d buck Soarin in the balls if he was doing that!”

“All right, all right, sorry, dancing frog, right,” Applejack shrugged, shaking her head. She really just didn’t care at this point, to be honest. Whoever it had been, why ever he’d been singing, he was obviously gone by now. “While yer out here, any idea what’s up with this storm?”

“Discord,” Rainbow muttered darkly. “I actually think he was telling the truth about it not being intentional, but it’s gonna last all night yet. At least we stretched it out; it was going to be a tornado at first! Totally radical, but totally not cool.”

“Well, Ah should be getting’ on back up to th’house then,” Applejack decided, standing up. “Care to join us for dinner? Maybe stay the night?” She added with a wink. Rainbow just rolled her eyes in response.

“Well fine then!” Applejack snorted, turning around to start out of the barn. “Spend the night in here with yer coltfriend then, fer all Ah care, just tell ‘im to keep the singin’ down!”

Suddenly, the muddy ground that was beneath Applejack’s hooves was above her head. Then beneath her hooves, over her head again, beneath her hooves… finally, a flash of sky blue and bloodshot magenta over her face told her what had happened.

“Why you buckin’,” Applejack growled as she glared up at a furious Rainbow. She twisted her powerful hind legs up, throwing Rainbow up over her head, sending her skidding through the mud outside the barn. Rainbow let out a squawk of surprise as they both scrambled back to their hooves, but then the lighter mare was lunging at Applejack.

‘Bill’ went flying as the two rough-and-tumble tomcolts rejoined the fray, rolling and nipping and kicking and flailing as the rain pounded down over them. Whinnies and half-articulated insults were swallowed up by the thunder as irritation was slowly swallowed up by the raw adrenaline that demanded they either fight or flee, and neither one was about to run.

Finally, Rainbow managed to get on top of Applejack, her muddy wings held wide, incidentally shielding the earth pony from the rain. Lightning flashed, silhouetting Rainbow against the dark grey sky, panting hard, her lips curled back to bare blunt white teeth. Applejack was panting just as hard.

Fight or flee. Flee or fight.

Applejack came up with a third option.

She leaned up, wrapping her arms around Rainbow’s neck and kissing her hard. Rainbow responded just as instinctively to the kiss as Applejack had to being tackled, pushing AJ’s head to the ground, grinding her blonde ponytail into the mud as the pegasus’ tongue forced its way into Applejack’s mouth.

Powerful muscles pressed against each other as bruises and scrapes were forgotten. Toned bodies practically steamed as their sides heaved for breath, tensing and relaxing alternately as legs started to tangle, hooves digging furrows in the slick mud.

“Y’all better turn around ‘fore everythin’s covered in mud,” Applejack groaned huskily.

“I’ll prove I haven’t had a stallion in me,” Rainbow grinned wickedly, flapping her stiff wings just long enough to kick up into the air and twist herself around, landing with her muzzle between AJ’s nethers, her own crotch firmly against the earth pony’s mouth.

“Ah’ll be inspectin’ ya mighty deep,” Applejack promised, promptly sealing her skilled lips against Rainbow’s slick blue pussy-lips, driving her tongue deep inside of her. Rainbow muffled her cry against the farmer’s soaked snatch, the two of them channeling the emotion and adrenaline of their fight into a desperate contest to see who could drive the other to orgasm first.

As it turned out, Applejack was the one to lose the contest, not that she was particularly prone to objecting. Rainbow’s pussy tasted heavenly, not the least hint of stallion blended with her lover’s distinctive stormcloud-and-passion flavor, and having an excuse to keep her tongue inside of it longer while she twitched and writhed suited her just fine.

Rainbow didn’t take much longer though, her body clenching down as she came, her head actually trapped between AJ’s thighs. Those powerful muscles flexing against her head, working with the mud beneath her to make breathing harder… it was a rush that Rainbow almost whimpered at losing when the farmpony finally relaxed and let her up.

“We… should get back in… the barn,” Applejack panted. “Granny’d kill me if’n Ah came in like this.”

“Nah… let’s just stay here for a bit,” Rainbow countered, crawling around so she could kiss Applejack, enjoying the blend of their flavors. “I don’t know about you, but… I think I’m starting to like this.”

As she closed her eyes tiredly, the rush of the storm, the fight, and her orgasm finally overtaking her, she could have sworn she heard a rich baritone voice singing and fading off in the distance.

“Gonna keep me warm, some rainy day when I’m lonesome… gonna keep me warm, some rainy day, when I’m blue… for you! Your love was like whiskey… in an old saloon! Just like an old coat, I’ve put it away! Gonna keep me warm… some rainy day…!”

Author's Note

I started planning on writing a brief argument between Rainbow and AJ about kink, followed by sex in the rain.

Somehow, I ended up with this.

Uhm... enjoy?
