Invasion of the Futa-Vamponies!

Two of the chairs sat empty in the meeting room of Twilight's castle. The ponies were supposed to meet to plan for the Nightmare Night festivities, but Applejack and Fluttershy were nowhere to be seen. In fact, nopony had seen them anywhere lately.

"Can you believe those two, skipping a party-planning meeting? This is an affront to party-ponies everywhere!" yelled Pinkie Pie as she slammed a hoof on the table.

Twilight was less rambunctious than Pinkie but no less concerned. "I hope Applejack turns up soon," she said, "I wanted to check with her that her family would be able to give us apples for the party's apple bob." She gave a sidelong glance at Rainbow Dash. "Oh, and the apple cider."

Rainbow Dash and Pinkie screamed, "No! Not the Cider!" The pair despaired at the possibility of a cider shortage and fell to quarreling over what should be done to prevent such an atrocity.

Rarity slid her chair back and stood, announcing over the commotion, "If you two are quite done, perhaps I could check in on our dear Applejack?"

Twilight looked to Rainbow and Pinkie, the pair uselessly shouting over one another. "I think that's a good idea, Rarity. She's probably so caught up in harvesting apples that she forgot about the meeting."

Though it was still daytime, the moon was visible in the sky, giving the orchard a spooky look that Rarity definitely approved of, given the season. Applejack and her kin were naturally in-tune with autumn fashions, Rarity mused. Now, if she could only get them to keep up with the fashions of the other three seasons...

Rarity creaked the door to the Apple Family's barn open. "Applejack? Are you there, darling?"

No answer.

All the windows were shuttered, so the open door formed a wedge of light that cut through the otherwise pitch-black interior. As the door opened further, the wedge of light widened, illuminating the middle of the barn like a spotlight, revealing something on the floor.

Rarity timidly trotted inward, eying the object. As she approached, she recognized it as Applejack's hat. That's odd, she thought, She never takes that thing off. Once she was standing in front of it, she lifted it off of the ground with her magic, dusting off the straw and sawdust from the floor. "I swear, that mare simply has no idea how to properly take care of her clothes!"

Then she noticed something else on the floor. There was a folded piece of paper on the ground, sitting where it must have been hidden under the hat. Scrawled on it, in what Rarity noted was some rather un-ladylike hoofwriting, were two words.

"Open me."

She scoffed. It was a bit early for Applejack to be playing a Nightmare Night prank on her, but she nonetheless unfolded the paper, levitating it up to eye level. Another message was written inside.

"BOO!"

All of a sudden, there was a clattering in the dark, and the screaming sound of rope as it rubbed against timber, leaving rope burns behind it. At her hooves, a snare had been hidden under the straw on the floor. The straw seemed to explode as the snare raced shut, hogtying Rarity. An instant after she wobbled to the ground, losing her balance, the rope yanked her into the shadows, leaving her screaming as the barn door slammed shut, drowning the barn in darkness.

Her head spinning, unable to see a thing, Rarity realized she was upside-down, suspended from the rafters by the rope around her hooves. She quietly cursed the darkness, her head spinning from the disorienting position. It took a few moments to focus enough to properly cast a spell, but once she did her horn started to glow. The middle of the room was bathed in weak, soft light, but deep shadows still hid much of the room. In the shadows between the beams that held up the hayloft, Rarity could make out a familiar face.

"Well, would you looky here?" Applejack teased, "I knew one of y'all would come 'round here sooner or later."

If this was a prank, Rarity was having none of it.

"Now, just you listen here, Applejack!" she roared in her most scathing voice, "Maybe your idea of a good jape is to truss somepony up in ropes, drag them through the dirt, and muss up their mane..." She clenched her teeth at that last point. How DARE she. "But some of us were not RAISED IN A BARN! I mean are you crazy!?"

"Sure am, sweetheart. Heck," Applejack said, "you might even say I've gone batty."

Rarity's retort died on her lips as Applejack stepped forward, letting the magical glow reveal her form.

Rarity knew what a vampony looked like. From lived experience, sure, but also from reading. But far from the suave, elegant vamponies that populated some romance novels that Rarity had read, Applejack was like a beast, with massive wings, slavering, fanged jaws, and between her legs...

Well, that hadn't been on any of the female vamponies in Rarity's novels. An erect penis dangled from Applejack's nethers. It was a few shades darker than her coat, more of a golden brown color than orange. As Applejack breathed in and out, the member pulsed and swayed, moving almost as if it had a mind of its own.

Rarity opened her mouth, meaning to shout, to maybe cast a spell, but before she could even form a thought in her head, Applejack pounced. She closed the distance with a single bound, aided by a single pump of her wings, blowing back the straw behind her like a hurricane. Rarity only had time to let out the start of a scream before--

*CHOMP*

Applejack's jaws were around Rarity's throat. Biting. Squeezing. Sucking. Rarity's scream petered out, silenced by the teeth around her neck. Her eyes fluttered as if she were getting very sleepy. Applejack was draining more than just blood. She drained her of her energy, her strength, even her sense of reason.

Applejack's mouth left her, and she snorted out a warm puff of air like a stud about to rut. She certainly had the equipment for it; Rarity saw, from her unique vantage point, an angry, thick vein pump blood to Applejack's cock.

Applejack followed her captive's eyes. She chuckled, "Heh, like you see?" as she lifted a leg to give a better view. It looked surprisingly hard for a cock that size. It wasn't dangling anymore so much as it was pointing straight at her. By the end of it, it was even curving up a little, with a shape that promised to stimulate all the best places.

Applejack broke her concentration. "You know, I wasn't certain which of my pals would show up, but I definitely ain't disappointed. A fancy, frou-frou mare like you is better than anything I coulda ever hoped for" She licked her lips. "Can you guess what I've got planned fer you?"

Rarity realized she was breathing as raggedly as Applejack now. Their eyes meeting, she answered.

"Are you going to..." Rarity gulped in anticipation, still feeling the vampony bite on her neck. "...have your way with me?"

Applejack's smile revealed her fierce fangs. "And here I thought Twilight was the smart one."

She circled her hogtied friend, one of her wings reaching out and pulling a sturdy crate from the edge of the room. Placing it behind Rarity, Applejack stepped up onto it, produced another rope, and lassoed it around Rarity.

She let out a girlish squeal as Applejack's frantic knotwork moved her about. After tying a few loops and knots, and undoing a few others, Applejack had Rarity right-side-up, the ropes cinched around her barrel rather than her hooves.

Up in the air like Rarity was, the pair weren't quite level with each other, the gray-colored flesh around Rarity's marehood and donut suspended at Applejack's eye level. But then Applejack reared up on her hind legs, resting her forehooves on Rarity.

"I hope you're ready fer this, cause I'm about to go hog-wild." Snorting and whinnying with primal need, Applejack mounted her.

Rarity bit her lip to stifle a moan. Everything about it felt so good. The length, the thickness, the feeling that curve gave every time the huge cock plunged in.

"Oh, fer' land sakes," Applejack groaned, "this pussy's more snug than a bug in a rug!" Her cock made sweet, sweet music as it spread Rarity's walls, stretching her to fit its shape. As Rarity kept biting down on her lip, Applejack yelled, "C'mon, I wanna hear you make some noise!" before shoving herself in past her medial ring.

"F-FUUUCKK MEE!!" Rarity screamed out as the curved shaft rubbed past her G-spot. She babbled, "Fuck me, fuck me fuck me fuck meee!!!"

Applejack laughed, "Well, shoot! What do you think I'm doin'?" She squeezed Rarity's plump ass with her hooves, rolling her cheeks before kicking the pace of her thrusts up a notch. "I can see why Fluttershy loved this so much," Applejack said over the loud smack, smack, smack as her balls slapped against her thighs. "Yer gonna love it too. Once yer a vampony, you won't be able to help yerself. None of our friends will!"

Rarity should have been mortified at the prospect of being turned into a vampony, but...

*Smack, smack, smack*

It had been a while since any stallion had made her this wet. The more she thought about it, the less becoming a sex-crazed vampony seemed like a bad thing. Applejack was awakening a primal, instinctual part of her that told her to surrender to the bestial cock.

Tied up in the makeshift sex swing, all Rarity could do was wriggle and grind her plot back against Applejack as the farmpony drilled her. As she wiggled about, she was rewarded with a hot bead of precum that squirted from the invading member.

There were still a few inches Applejack couldn't get in from the lower angle she was at. Rarity felt her attempts to get them in, growling in frustration while standing on the tips of her hooves or trying to jump up on her like a dog.

Rarity was about to voice a suggestion, when Applejack growled, "Agh, fuck it!" and yanked her member free. Rarity felt empty without it inside her.

She whined, "Darling, why did you stop--" *Fwhump!*

Applejack beat her wings, lifting off the ground. Raising herself above Rarity's plot, she aimed her cock at her captive's gaping pussy. With a whoop of ecstasy, Applejack threw her hips forward, plunging her cock deep inside. Rarity held nothing back, letting out a very un-ladylike moan as the girthy appendage stretched her out.

Applejack was perched on Rarity's hindquarters, holding herself in place with her hooves wrapped around her partner's flanks, and her cock lodged securely in her pussy. With nothing touching the ground, the pair swung like a pendulum each time Applejack pounded her hips forward. Back and forth, back and forth. The whole while, Applejack never lost her balance, the product of years of practice at rodeos.

From this angle, Applejack's thrusts could follow the curve of her shaft, bottoming out with every thrust. Every time her hips pounded into Rarity's rear, a juicy smack clapped out from their nethers, now soaked in Rarity's wetness.

A growl formed in Applejack's throat as her thrusts lost their rhythm. As the rope swung from the rafters, the beams creaked from the strain of each thrust. Rarity felt her flat tip flare out, a sign of what was about to come.

Applejack opened her jaws, sticking her tongue through her fangs as her throat loosed a debauched roar. Like a garden hose, her shaft straightened out as cum gushed through it. A single continuous rope of cum flowed out, filling Rarity with enough jizz that her belly seemed to grow a little paunch.

A backflow squirted from her pussy, dripping to the ground in a loud splat, painting the barn's floor white. Rarity could smell it, the potent load saturating the air with its earthy scent. The weight of the load being pumped into her was so much that she could feel her center of gravity shift, tilting back as Applejack slid her cock out. When the flared head popped free, a stream of cum trickled out from her parted lips, washing over her clit.

Rarity cooed with satisfaction as the warm afterglow took her, but Applejack just stared at her, panting wordlessly.

"Applejack, what's the prob--AAHHH!!!"

Rarity's back arched with a sudden spasm. The magically mutative cum took effect, reshaping her. She felt herself morphing into something monstrous and terrible and beautiful.

Ropes strained and snapped with a loud twang as a pair of wings grew out from her back. Before she could hit the ground she instinctually flapped the newly formed limbs. Between her legs, new flesh magically formed, and moments later a penis of her own hung from her, swaying freely in the air.

When Rarity touched the ground she stretched her wings out, admiring their beauty. She folded them behind her like a cape, ever the fashionable mare. Rarity ran her teeth over her fangs. "Well, the wings are lovely, but the fangs may be a tad gauche."

She threw her head back to look at Applejack and ask, "What do you think, darling? Is it a bit much?"

Applejack replied, "Oh, I think you're ready fer a night on the town." Both ponies grinned as Rarity's cock throbbed in anticipation.
