Invasion of the Futa-Vamponies!

A cold autumn wind breezed through Twilight's mane as she walked up to Fluttershy's cottage. Nightmare Night was only a few nights away, but nopony had seen Fluttershy in days. She usually hid in her cottage on Nightmare Night, afraid of even the least scary costumes, but that was still some days away. Was she afraid of even seeing ponies getting ready for Nightmare Night this year?

Twilight shook her head. And here she was, thinking that Fluttershy had toughened up a bit. She was such a scaredy-pony sometimes!

As she knocked on the door, it swung open. "Hello?" Twilight called out, "Is any-creature home?"

The house looked like it had been abandoned for days. Dust and cobwebs were starting to crop up, but Twilight supposed that for all she knew, Fluttershy might have just started taking care of a family of spiders. "Fluttershy?" Her voice echoed in the empty house. "Angel-bunny?" No answer. "Discord?"

Twilight trotted over to a nook in the corner with papers strewn everywhere. Evidently, Discord had been working on some kind of project, as the papers were piled under an armchair that was somehow sitting on the ceiling.

The papers were labelled "Nightmare Night Plans", and had a list of ideas written under them. Most were scratched out, with a note scrawled next to them.

• ~~Zombie Apocalypse~~ (What is this, 2008?)
• ~~Were-Rabbits~~ (Dreamworks would sue my ass)
• ~~Ponyville Chainsaw Massacre~~ (Too gory)
• ~~Flutterbat~~ (Already used that one)

It was all nonsense. But Twilight noticed that under "Flutterbat" was an idea that had been circled with a pen instead of being crossed out.

"FUTA-BAT!"

*SQUISH*

Applejack cussed as she accidentally stepped on yet another wrinkly, de-juiced apple, not having seen it in the dark of the night. The desiccated fruits were everywhere, all over the orchard. Tons of Sweet Apple Acres' prize-winning apples had been reduced to worthless mush by some rotten varmint, and Applejack was going to get to the bottom of it tonight.

Her first thought was pranksters. The local colts sometimes pulled pranks like this close to Nightmare Night, but she had dropped that theory when she saw the bite marks in the apples.

Bats. It had to be bats. She thought those darn things had promised to leave her crops alone, but clearly the winged rodents needed to be taught a thing or two about messing with the Apple family. Those apples were supposed to be used for treats and bobbing for apples on Nightmare Night. She wasn't about to let them ruin that, even if Fluttershy would throw a fit about Applejack not showing kindness to the bats. Sometimes that pony was too gentle for her own good.

Applejack was completely unaware of a pair of blood-red eyes staring from behind her. Hanging from a bough of an apple tree, a shadowy figure stretched out one huge, webbed wing, then another. It silently dropped from its perch, gliding towards the unsuspecting farmer. Bat wings usually made lots of noise, but this creature had a lot of experience being quiet.

Oblivious to her impending fate, Applejack rolled over another drained apple. "I swear, the critter doin' this must love apples almost as much as I do."

Applejack turned her head at the last second, just enough to see who was swooping down at her.

"Fluttershy!?"

That made no sense! Sure, Flutterbat was an apple-crazed menace, but Fluttershy hadn't been a vampony for years! It did answer the question of who'd been sucking all the apples dry, but --

Wait, what was that between Fluttershy's legs?

*WHUMPH!*

Applejack crashed to the ground flat on her belly, her hat flying into a pile of leaves in front of her as Fluttershy landed on her back. Fluttershy panted, her face flushed with pent-up desire as she straddled her prone friend. Looking behind her at the space between them, Applejack stared, unable to explain what she saw.

A length of hardening stallion-meat hung from between Fluttershy's thighs, pressing against Applejack's exposed crotch. From the yellow at its base, it mottled out to a pink that nearly matched the color of Fluttershy's mane.

"Fluttershy, what...what in the hay is goin' on?" Applejack asked. "I can almost understand what you've been doin' to my apples. Heck, I love them so much at times I'm amazed that our family hasn't put ourselves out of business by gobblin' them all up."

She shook her head, trying to focus on the problem of the moment, rather than her own apple-related issues. "But what are you doin' with them bat wings again, what are you doing with a big ol' pecker like that, and what," -- She raised her voice -- "are you doin' pressing it up against my cooter!?"

Fluttershy answered by giving Applejack a ravenous look, practically drooling as she stared at her neck. "I'm sorry, Applejack," Fluttershy squeaked. "I just woke up like this! I scared myself half to death when I saw what I looked like, but after that, all I could think of was sinking my teeth into a nice...juicy...oh, sweet Celestia..." Fluttershy practically drooled as thoughts of apples clouded her mind.

"Okay, okay," Applejack said, trying to get her back on track, "but none of that addresses that." She stared at the throbbing member as it pulsed with Fluttershy's heartbeat.

Fluttershy blinked, almost as if the cock was the less surprising thing about her. "Oh, this? It showed up along with everything else that changed." She puffed a breath of air out her nose as she bit her lip, and she unconsciously shifted her hips, dragging the head up and down Applejack's lower lips.

"It feels really good, you know. I tried touching it, but just hasn't...gone...down..." Looking down at her mare-cock, Fluttershy's eyes fixed on Applejack's cutie mark.

"That's right...you're also an apple, aren't you?" Fluttershy was getting a crazy look in her eyes. A look that Applejack really, really didn't like. "A plump, juicy apple, right in front of me!"

Fluttershy's mouth opened, baring a pair of fangs as her lips curled hungrily. "I bet...haah...you taste...delicious!"

As Fluttershy moved forward, the smell of apple juice on her breath, Applejack tried to escape. She yelled, "Dang it, girl! Get a hold of yerself!" The pair thrashed about in the grass, but Applejack couldn't buck the weight of a full-grown vampony weighing down on her back.

She panicked as Fluttershy's mouth darted forwards to strike her neck. She shouted, "Get offa' me!" as she dodged the blow in the only direction she could -- backward. So spooked by the prospect of being bitten by a vampony, she didn't think of where Fluttershy's new cock would go when she bucked her hips behind her.

Applejack's muscles froze as the first few inches of cock spread her walls, invading her tight pussy. She was speechless, but Fluttershy let out a long, lusty moan, crying out, "Hmmnhh...ooh, yeah..." With Applejack too shocked to move, she plunged two hypodermic fangs into Applejack's flesh. A trickle of blood flowed from the vampiric kiss, and Applejack stopped trying to buck Fluttershy off altogether.

She blinked slowly as if she were drunk or in some kind of trance. Her breath slowed from panicked gasps to a slow, heavy, lusty pace, matching Fluttershy's own breaths. Why was she fighting this? It felt so good, Applejack couldn't remember why she had tried to buck Fluttershy off.

As Applejack sank under her vampiric spell, Fluttershy opened her mouth, leaving behind a pair of perfect red dots where her teeth had been on Applejack's neck. Fluttershy timidly asked, "Applejack? Are you okay?"

"Ye-yeah...I ain't bleedin' out, if that's what you mean," Applejack struggled to reply. She felt so woozy, like her head was stuffed with cotton.

Fluttershy paused for only a moment before responding, "Good. I'd hate to do anything to hurt one of my friends," as she began pumping her cock into the farm-pony's cooch. Applejack could swear that the cock was getting bigger, as if her stolen blood was being pumped straight into Fluttershy's boner.

Applejack collapsed back onto her belly as the strength drained from her legs. Fluttershy was undeterred, quietly oohing and aahing as her shaft massaged every nook and cranny of her friend's hole. She crooned, "Oh my...you feel so perfect. It's like...like your plot was made for me." Fluttershy rubbed Applejack's cutie mark with a hoof. "I think this is my favorite apple yet."

Applejack was surprised that such a dainty pony could have such a big cock. Pressing against the grass of the orchard, she surrendered herself to Fluttershy's uniquely demure brand of sexual domination. Her muscles relaxed, and as her Kegels stopped tightening around the girthy organ penetrating her, Fluttershy tilted her hips and drove herself forward in a spectacular thrust.

A moan escaped Applejack's mouth as she was filled completely, giving in to the pleasure of getting fucked. As Fluttershy pulled out and plunged her length back in, she could feel the shape of her through her belly, rubbing against the grassy ground.

As the moon peeked through the clouds behind them it cast a clear shadow in front of the pair of ponies. Applejack watched the silhouette of Fluttershy arch her back, rearing up as her thrusts grew more erratic, more feral. The shadows of her wings flung out from either side as Fluttershy shot them out, squeaking in pleasure.

"Applejack, I'm so...s-so close..." Fluttershy's hips were a blur, her balls plap-plap-plapping against Applejack's rear. "I can't hold it...I...I...Aaaaaiiiieee!!" Her shriek rose in pitch past the edge of hearing, sending all the bats in the orchard into a frenzy as they flew out of their trees.

Fluttershy froze in the ecstasy of her impending orgasm, her breath catching in her throat. Applejack could feel Fluttershy's balls pull up towards her cock, pumping out their payload of vampony-batter. As the vampiric seed gushed out of her flared stallionhood, Fluttershy's breath returned to her, and she let out a few demure, whimpering moans that did not at all match the virility of her lower half.

Applejack's own moans were quieted as Fluttershy flung her wings in front of her, wrapping them around the farmer's face. It was like she was in a cocoon of darkness, her belly getting filled with rope after rope of hot, gooey cum.

After what felt like a lifetime trapped in that darkness, though it was only a few moments, Applejack saw the night sky again as Fluttershy let go, tumbling off of her. There was a wet, sucking sound as the fleshy length pulled out of her, and for a few moments the pair lay exhausted in the wan moonlight.

Their chests rose and fell as they took deep breaths, exhausted. Applejack was about to say something, but words left her as she felt a sensation almost like indigestion.

Deep within her, she felt Fluttershy's cum doing something. The warm feeling in her belly grew hotter until it felt like a searing heat spreading throughout her whole body. "Wha...What's goin' on?" Applejack asked as she wobbled to her hooves.

Fluttershy watched, eyes wide as her jizz, loaded full of vampiric DNA, leached into Applejack's body, doing its work. Its magic corrupted her, befouled her, changed her. Her ears began to grow out into bat ears, twitching and twisting to catch every sound. Her eyes took on a deep, sanguine red. Her mouth opened in a scream halfway between orgasm and agony as her teeth formed a set of needle-sharp fangs.

The flesh of her back seemed to ripple as changes occurred underneath, old bones shifting as new bones were magically formed. Her skin bulged out, making ungodly noises as a set of membranous wings grew out.

Her transformation almost complete, Applejack reared onto her hind legs and spread her wings. Against the light of the moon, her rampant silhouette cut a fearsome figure. Applejack let out a long, high shriek like a bat as the final change occurred. A long, engorged cock that rivalled Fluttershy's own took shape, coiling out from where her marehood had once been.

When her change was complete, Applejack stood, gasping from a mix of exhaustion and lust. "Fluttershy, it feels so...so..." Applejack trailed off, distracted by the incredible throbbing feeling she felt between her legs

"Good?" Fluttershy tried to finish for her.

She shook her head. "Amazin'!" Applejack corrected her. The member slapped up against her undercarriage as it throbbed, making her groan in pleasure. "We gotta do somethin'...or show somepony!"

Applejack's own eyes took on a crazed look, as her mind filled with the same compulsions as Fluttershy's. "We gotta show our friends!" Thinking of the other Elements of Harmony, her cock twitched like an animal that had scented its prey.

"We gotta show everypony!"
