>Day banana in Equestria.
>You are Anonymous.
>Stuck in a world of technicolor horses.
>They prefer to be called ponies though.
>Despite being as large as the galloping equines from your world.
>But much rounder and louder than the stupid animals you once knew.
>Well, except for one “pony.”
>Fluttershy.
>She's as quiet as they come, but pushier than a pissed bull.
>Constantly trying to find out what “melts your butter.”
>Or “greases your gears.”
>Mare can't take no for an answer when you say you're not interested.
>But she wanted a piece of your piece.
>Even though body proportions say that it'll be like throwing a hotdog down a winking hallway.
>Hasn't stopped her yet.
>Her advances eventually devolved into random fetish guessing.
>It was cute at first, but quickly got tiring.
>Waking up nearly every morning with her dopey, hopeful face at your doorstep, your patience grew thin.
>Hoof play, diapers and peanut butter are just a few of her guesses.
>Yesterday's guess was bestiality.
>You did not want to know where she put that Blue Jay.
>Or what it did once it got there.
>You squint as the morning sun burns through your eyelids as you lay on your bed.
>Cursing the beloved alicorn's name, you start your morning routine.
>Shit, shower and-
>Ding-dong.
>Shiiiiiit...
>Grabbing a towel, you make a bee-line for the front door as you cover yourself.
>Might as well get this over with.
>Twisting the golden knob, you throw the door open.
>The first thing that assaults you is the cold.
>Forgetting that it's the middle of winter, a gust of icy goodness cuts the surface of your skin.
>Shivering, you hold the towel close to you as a large figure blocks a bit of the biting wind.
“No Fluttershy that isn't my-”
>”Well, good thing I'm not Fluttershy, huh?”
>You double take at the towering figure in standing in your doorway.
>Facing a fuzzy purple pillar, the color and height reveals Twilight Sparkle to be your early guest.
>Your eyes slowly trail up to reveal the distinct snout and purple eyes of the magical mare.
>Something was amiss though.
>Used to Twilight's cheery demeanor, the lack of life in her words and frustrated expression took you off guard.
>Staring confusedly at your friend's invisible predicament, she steps aside to reveal the real problem.
>Fluttershy stands just slightly behind Twilight, a forced smile creepily hanging on her mouth.
>Your mood immediately sours as the bookish pony backs up, allowing the yellow menace to fill your vision.
>”Hello Anon, I think I finally-”
“Nope, not my fetish, thanks for coming you two-”
>Before you can slam the door, a purple aura holds the wooden blockade completely still.
>You flash your omnivorous teeth threateningly at Twilight, as she repels your stare with a snort of her nostril, face still displaying mild irritation.
>The warm torrent of air briefly caresses your body, a welcome change to the biting weather outside.
>Eager to retreat to the confines of your humble abode, you cross your arms and face the obsessive pegasus.
“Fine, make it quick, I don't want to catch a cold.”
>A twinkle of hope flashes in Fluttershy's eyes as she hovers above the ground with a gentle beat of her wings.
>She nods to Twilight, who cracks her long neck in response.
>”Anon... is vore your fetish?”
>Before you can retort with a guffaw, Twilight drops her jaw effortlessly as Fluttershy plugs her rear hooves into the gaping mouth of the alicorn.
>Your eye twitches as the butter pony goes in dry, the purple princess digging into the ground trying to support the new weight.
>Fluttershy does her best impression of an underpaid porn actress as she bullies her way into the reluctant throat of her friend.
>”Ohhh... Ahhh... yes... swallow me down...”
>You stand frozen, not because of the temperature, but because of how bizarre this was.
>Seeing Twilight roll her eyes at the fake sounds of orgasmic pleasure, you hear her gulp painfully as the rounded rear of the crazy caretaker slowly creeps into her mouth.
>The vague shapes of hooves bulge out awkwardly from the throat of the magical prodigy.
>Fluttershy blushes fiercely as you stare, her descent excruciatingly slow as Twilight burps up air.
>The bubbles of gas vibrating against the yellow pony's skin, making her shudder in pleasant shock.
>She bites her lower lip as she struggles to speak through her moans of pleasure.
>”Twilight... that feels so...”
>She squeaks as her entire body convulses, the blue eyes rolling to the back of her head.
>On the other hand, Twilight's eyes dialate as her friend just unloads a stream of sticky release all over her tongue.
>Like bad medicine, the studious pony closes her eyes as a series of urgent swallows quickly consumed the dazed pegasus.
>Before you knew it, the dopey face of the shy pony eases itself into the moist cavern of Twilight's maw.
>Closing her lips around the shapely head, Twilight takes a deep breath through her nose as the long pink mane dangled from her lips.
>The weak movements of the perverted mare poked through the purple coat, the distinct shape of a rump pressing hard against the base of her neck.
>With a few more gulps, Twilight slurps up the remaining evidence of Fluttershy's existence, the pink spaghetti slithering into the parched throat.
>She has a brief coughing fit, a few stray yellow hairs flying from her empty mouth as she sighs heavily.
>”Ugh... her coat absorbed everything...”
>You stare at the large, pony-shaped gut of the princess, unable to rip your eyes away.
>Twilight silently lets out a few, lengthy belches as her paunch slowly shrinks around the meek pegasus.
>The weak struggles soon turned into tiny twitches as Twilight's belly shrinks enough to not drag across the ground.
>Her stomach growls and gurgles as it strains to pulverize the large meal.
>”My eyes are up here Anon.”
>You shake your head, realizing that you've been standing in your home, slack-jawed at Twilight's noisy belly.
>”If you don't mind, I'd like to come in while she passes.”
“Uhh... okay?”
>A frigid breeze wakes you up, making you stand aside as the wide alicorn shimmies her way pass you.
>”Oh, watch where you're pointing that thing, might put an eye out.”
>You raise an eyebrow as you shut the door.
>Your eyes drift downward as you're greeted with an erection harder than diamonds.
“God... DAMNIT.”
>”Looks like she was right this time... urgh...”
>You see Twilight flop on her side in your living room, breathing heavily from the heavy weight settling in her stomach.
>Adjusting the towel to accommodate your own perverted passenger, you walk to Twilight's side.
>Bubbles and groans noisily play from her paunch, slowly churning its contents.
>The pony's wings twitch erratically as she strokes her stomach to settle down.
>Watching the inviting flesh bob up and down from her breaths, you take the soft middle in your hands.
>You slowly knead the lumpy middle, eliciting a few sighs of relief from the alicorn.
>“Thanks... she's quite a hooffull.”
>Making eye contact with your welcome guest, you venture a question.
“Well... is this alright?  I mean, I'm not complaining.”
>Twilight giggles at your reluctant celebration.
>”She wanted to test some weird spell she found in the old castle library.  Obviously she wanted to come to me to test it... and it seems safe enough... but ugh...”
>Her stomach pulses against your touch, unable to deal with the heavy load within.
>You gradually caress the area, letting nature take its course.
>Hearing her hum in relief, she continues.
>”She'll just be in me for the winter while the animals hibernate, the swallowing part is hopefully the hardest part of this symbiotic relationship.”  
>Nodding ignorantly, you focus on the steadily shrinking belly as you press elbow-deep into the elastic, warm flesh.
>You hear Twilight giggle throatily as a foreleg wraps around you.
>Gripping you close against her body, you feel the mushy contents rumble as they empty into the rest of her body.
>”Got you now, Anon.”
>The dainty whisper sends shivers down your spine as you glance at her eyes.
>Recognizing that manner of hushed speech from anywhere, Twilight's irises glowed a baby blue.
“What.”
>”Didn't think I'd let you off so easily, now did you?”
>You struggle to get out of the possessed pony's grip, but the thick leg that stood wider than you proved impossible to budge.
“How do you even...”
>She gives another sultry laugh as she moves on top of you, her padded belly pinning you on the carpeted floor.
>”I didn't tell Twilight everything about the spell, now that would just ruin the surprise.”
>Twilight's face fills your vision as Fluttershy speaks through a voice that was not hers.
>”Now... let's keep our friend warm for the winter, together.”
>The lips that were mere inches from your face parted, revealing the salivating maw.
>She thrusts her head forward, gently biting down on your chest as she licks your face.
>Completely drenched in drool, the tongue mercilessly grinds against your head as you sputter out any oral fluids that were not yours.
“Ugh... Twilight, help... please?”
>Sucking you out of the towel that once dangled from your waist, a booming “Nuh-uh” came from the esophagus that dilated to greet your body.
>A quick slurp was all it took to throw you deep into Twilight's throat.
>Already warmed up from its previous encounter, the stomach's entrance yawned open as your hands slip against the slick walls of the gullet.
>You hold your breath as your persistent member, still hard from earlier, bumps against the ribbed walls of the muscular passage.
>Soft, oily flesh presses against your stiffness as your torso makes its way into the groaning organ below.
>The entrance to the stomach clamps down on your abused groin, forcing a quick orgasm to spray out as you drip your load into the soupy mixture below.
>Losing the will to fight, your body dangles limp in the muggy chamber as the throbbing ring wrapped around you releases you into the bubbly liquid.
>Twilight's belly rumbles around you as you lay into the wrinkled walls, completely covered in the gooey leftovers of the horny mare.
>The suffocating heat saps all energy from you as the walls creep in closer with each beat of the pony's heart.
>Before you lose yourself to the oppressive atmosphere, you hear Twilight sigh in her own voice as you melt into the thick concoction.
 
>One month later, Twilight sits atop her bed wrapped in her own covers.
>Her eyes peruse a book as she takes a sip of a levitating glass of hot cocoa.
>She yawns loudly as her body emits a low, hollow gurgle.
>”Yeah, yeah... one second...”
>Throwing off the covers, she jumps off her bed with a loud thump.
>She gives herself a quick glance in the mirror.
>Her belly hung slightly lower than normal, lined with more than just her own fat.
>The trunk-like legs, once thinner to match her alicorn growth returned to their stubby girth.
>Even her neck that began to grow out retained its previous width with all the excess nutrition she gave her body.
>Though your bodies did keep her warm in winter, the torrent of thoughts that swirled in her mind was an unwelcome change.
>Flutterbutter's thoughts were nothing but a menace, dreaming of entrapping you forever with her.
>On the other hand, you behaved, watching the world through the mare's eyes.
>You appreciated every step and every stretch of her muscles as you felt each sensation on her body.
>The breeze that caressed her underbelly and the warmth of the cocoa that played on her lips.
>Even giving Twilight your thoughts on her research made you a welcome guest.
>Perhaps you could ask her from some “overtime” later.
>For now, Twilight mixed herself a hearty salad for three.
>Her leg twitches involuntarily and wings flare out as the invasive thoughts raided her mind.
>She did her best to shake the thoughts from her mind, as one single phrase boomed to clear her mind.
>”Fucking Fluttershy...”
