"Ah! Fluttershy, whaddya think yer doin'!?

Applejack squirmed, trying to get out from underneath Fluttershy. She wasn't quite sure what was going on. One moment the two mares were working together on the farm, the next the pegasus had pounced on her like some rabid dog.

"I-I'm sorry AJ, I-I'm just..."

Fluttershy squeaked and bit down on her bottom lip. The blush already present on her face intensified, darkening to a deep flush as red as the apples Applejack and her family so prided themselves upon. The typically shy pegasus' maw openly slavered above her, spit dribbling down her chin and landing onto AJ's chest. More disturbingly, Applejack felt a heat above her loins, and looked to see where it was coming from.

Her emerald eyes went wide, and the freckled farmer redoubled her efforts to remove herself from her prone position. She kicked at Fluttershy's flanks, not wanting to hurt her friend but doing her best to dissuade the pegasus from what she was implying. Instead, her hind hooves merely bounced off Fluttershy's bountiful cheeks, which went on to ripple wildly.

There, between Fluttershy's thighs, she saw the source of the typically reserved pony's apparent distress. Her balls were huge and engorged, each cauldron of cum rivaling the size of a cantaloupe. Her stallionhood was unsheathed as well, standing proudly at a full length that measured as long as her torso and about as thick as her hoof. When it throbbed, it slapped audibly against her belly, and from the blooming flare dripped a thick gob of heady pre.

Panting, Fluttershy finished her sentence. "I'm just so horny..."

"N-now, what's that gotta do with anythin'? How am ah supposed to help ya with that?"

Applejack knew the question was pointless. It was clear what Fluttershy wanted to do - by the way her bright teal eyes had gone misty but all the same laser-focused, how her breaths came short and fast but heavy, Fluttershy was in a deep, deep rut. But, perhaps, Applejack could draw her attention away long enough to extract herself.

Looking back on the day's events, AJ realized she probably should have been able to tell something was wrong. She'd noticed Fluttershy's blushing, how she'd been quaking and whimpering - more than she usually did, at least. But she'd brushed it aside, figuring that farm work was something she wasn't as used to doing. With it being the tail end of winter, Applejack recruiting her to assist with clearing leftover snow from Winter Wrap-Up for the spring harvest, the chillier conditions had only justified those beliefs.

But nippy weather didn't make a mare squeeze her legs together. Hard labor didn't make her eyes seemingly fall time and time again on the generous, muscular swells of Applejack's rump.

Nor did it make a mare pin her down, lower herself, and then start grinding her sweaty balls against hers.

"F-Fluttershy! S-stop it, don'tcha know that touchin' balls is gay?"

Fluttershy nodded, but didn't pull away. Applejack could sense how full Fluttershy's nuts were, overly laden with the burden of spunk that always yearned for release. It made her own sack tingle, her own testicles throb and swell and churn. The flush reddening Fluttershy's cheeks soon made itself known upon hers, too.

"I-I t-t-thought, since you're a dickmare too, y-yo would understand. P-please don't be angry..." Fluttershy whispered. Her voice was high and trembly, pleading but similarly oozing with sexual need from every syllable.

Applejack couldn't help but feel a little bad. She did know how Fluttershy felt - those days or even weeks when her body pumped hormones into her system, when her brain turned to breed-hungry mush. She'd want to stick her dick in a wet hole so fucking bad, pound it 'til the cows came home and so did she. After a point, it wouldn't even matter whether or not that hole was fertile, as long as it was a hole period, warm and wet and greedy for cock.

"A-alright." She relented. "Ah'll... h-help ya out."

"Th-thank you, thank you, thank you..."

Fluttershy kept repeating the phrase as she began humping against Applejack, the words gradually growing quieter and devolving into lewd moans and whimpers. Her hips rolled in slow, small circles, but every so often she'd raise herself high and then come down so their respective pair of seedbanks would 'plap' together with sweaty moistness. Soon, Applejack was meeting the motions back with her, orbs beginning to fatten with cum, her own horsecock sliding out from its sheath. It didn't take long for her growth to catch up with Fluttershy's, and her horniness followed not long after.

Pre-spunk flowed freely out of their tips, slicking up their meaty lengths with lube until their bellies and shafts were slathered in it. Surprisingly, Applejack felt her orgasm approach before Fluttershy. Her lust had overtaken her though, and cumming by frotting wasn't enough. She wanted more, and so she ceased her movements and nudged Fluttershy's side with a hind leg.

"Mah ass," she said, slurring a bit. She reached down with her forelimbs, teased apart the edge of her asscheeks, and spread herself wide. Tucked in her tush and protruding outwards was her ponut, as large and homegrown as the rest of her. It winked, not unlike a mare's pussy, and although she couldn't see it Fluttershy could feel how hungry it was.

"Fuck mah ass. Ah'll let ya cum inside, bloat mah belly."

Fluttershy didn't need to be told twice, or once for that matter. She quickly realigned herself, planted her back hooves firmly into the ground and against Applejack's freckled butt. Her cock dragged itself along orange-furred belly, drooling a line of pearly slime where it went - including in the crease of AJ's succulent apples - until the crown nestled nice and cozy to the country girl's pucker.

With a softly spoken grunt, Fluttershy drove her hips forward and every inch of aching fucktool into Applejack's squelching depths. The profuse amount of lubrication allowed her easy entrance, and the one thrust proved sufficient to tether herself root-deep. Either that, or Applejack was used to taking it up the ass. Judging by how hard Applejack squeezed her muscles around her dick though, and how loud she moaned, it was likely the latter.

Between Fluttershy's need for release, Applejack's tight hole, and the hotness of getting to plow one of her best friends silly, her dam burst before she'd gotten more than a few thrusts in. Applejack came even earlier, blowing her nut all over - and above - herself, the goopy white strands plastering themselves to her face and blonde mane.

Fluttershy's meanwhile poured itself out like an overturned pot of brew into AJ's gut. Her stomach distended, slightly at first, then more and more like she'd swallowed an exercise ball. By the time Fluttershy had drained herself, Applejack's upper half was painted a new shade and she looked eighteen months pregnant.

Lazily, the pegasus let herself flop onto Applejack's waterbed of a torso. Warmth radiated from it, and the whole thing wobbled pleasantly. A sound peaked Fluttershy's interest, and her left ear rose and swiveled to meet it.

Applejack was snoring. Fluttershy grinned with the tiny amount of energy she had left, and used the rest to lick AJ's face clean of as much salty marespooge as possible. Then, yawning, she fell asleep shortly after. Hopefully they wouldn't be found by anypony before they woke up.
