Twilibus

It was a dark and stormy night over Ponyville as the moon loomed over Twilight’s castle giving off a foreboding vibe. The princess of friendship was going through a rather unique experience that some of the townsfolk have noticed.

A few days ago Daring Do had recently sent a mysterious crystal idol she found in Trotsylvania while exploring a recently excavated crypt. She didn’t hear of any tale or rumor about said idol and was radiating a powerful magic aura, so after writing Rainbow Dash she later had it sent to Twilight to study it rather than to a museum.

After receiving it Twilight dug deep into research about it and soon learned of a group called the succubus mare league, which were a group of ponies all mares who had crafted an idol using powerful magically charged crystals that turned them into succubus ponies. The idol however soon was locked away by the head of the league after a battle for supremacy among the other members and marking them as hers with her cutie mark marking their wombs as a sign of domination. It is unclear afterwards what happened to the league but from the research only the odd idol was the last remnant of they’re existence.

Some time after acquiring the idol began the changes with anypony who hung around the castle. Twilight and her friends had recently started gaining odd horns that had begun sprouting up, they so far looked like nubs but other than that nothing much of note has happened to them physically. Twilight is also trying to research a counter spell or preventive for the magic of the idol as well.

In her study a frustrated Twilight huffs annoyed as she continues to dive deep into her books, searching for any sort of record of the league’s members familial ties and if any living relatives are still alive and where they are. But alas none of which bore any fruit and there are no leads whatsoever.

She has however made notes of supposed succubus related occurrences since the league did change into them to become succubi ponies. Noting physical transformations such as additional horns, change in eyes, tongue and addition of bat-like wings. Along with potential mental changes as well but aside from the new set of nubs nothing worthy of note lately.

“Ahhh come on!” Twilight complains aloud to herself, throwing her hands in the air. “Another dead end lead,” she mumbles before tossing the book aside and cracking open a new one and scanning through it. She has been working tirelessly for the past few days and rarely even sleeps anymore due to this idol, her curiosity far out stripping her basic needs at times with having to be reminded to sleep and eat. Her mane has become unkempt and frizzy and bags hang under her eyes and she has become a bit cranky to boot.

“I need a break,” Twilight comments, closing the book she was reading and rubbing her eyes. “Still nothing, they just all up and vanished,” she mutters to herself as she gets up and begins heading to the kitchen.

Grumbling to herself the whole way to the kitchen she opens up the fridge and fetches a bunch of bananas, some strawberries and a carton of milk tossing them into the blender and quickly blending them together for a smoothie. She detaches the container filled with the fruity goodness and pours it into a large cup and begins to chug some of it down as she sits her shapely ass onto a stool.

“This is driving me up the wall,” Twilight complains to herself before taking another big swig of the fruity concoction. “All I have to show for is a basic history and an idol that is emitting a unique glow,” she whines pouting as she takes another gulp.

Down the hallway a distant but familiar posh voice echoes.

“Hello!? Is anypony home!?” the voice asks, causing Twilight’s ears to perk up.

“In here Rarity!” Twilight shouts back.

The seamstress comes down the hall and enters the kitchen to find the stumped Twilight still drinking her smoothie. Rarity was as she always was dressed to the nines in a dressy casual outfit she designed herself which is a sharp contrast to Twilight's too big sweater that covers her entire body. And along with Twilight some odd nubby horns have begun to sprout from prolonged time hanging around the castle.

“Goodness darling you look like a stampede ran through you twice over,” Rarity exclaims at Twilight’s look. “And then beat you with an ugly stick… that was on fire,” she adds.

“Gee thanks,” Twilight mentioned, as she starts fixing her mane a bit but somehow makes it worse.

“That’s it I am taking over,” Rarity mentions grabbing Twilight by her collar and dragging her off.

“H-hey what are you doing!?” Twilight exclaims.

“I am fixing the tragedy that you have allowed yourself to become,” Rarity states as she drags Twilight to her chambers.

“My smoothie…” Twilight whines about as she is dragged off.

Rarity takes Twilight to the castle's royal bedroom and throws Twilight on the bed and gets to work, like a one mare beauty repair team instantly getting rid of the bags under her eyes and fixing up her mane in a flash.

“Alright now let me see if I can find you a proper outfit aside from that,” Rarity mentions opening Twilight’s vast wardrobe. “Shame Spike had to go to Dragon Con, otherwise I could use the help,” Rarity mutters to herself as she begins her search. “And not just with the wardrobe,” she adds to herself.

Letting out a sigh before rubbing her temples, she has been working non-stop and hasn’t given herself any time to unwind. She even hasn’t had a chance to give the Prototype Ejaculation-Capable Kinky Equine Replacement some usage in a long time, since she is constantly researching. Come to think of it she does feel a bit of an itch that needs scratching and it just so happens a rather voluptuous mare is in her room, she notices as Rarity bends over she can see what looks like red laced panties hidden under Rarity’s skirt.

“That slut,” Twilight whispers under her breath so her fashion and beauty consultant can’t hear her, And slowly Twilight begins to hatch a plan. “So Rarity did I tell you that I have been making leaps and bounds in my research as of late,” Twilight lies with a sly grin.

“Really? That may explain why you are up all night and day,” Rarity mentions with some concern. “You must take better care of yourself darling,” she politely scolds the book horse.

“Yes I think I discovered how the leader of the league became in power was due to her ability to absorb the auras of the ‘lessar succubi’ to empower her very own aura as the more dominant one,” Twilight continues trying to entice Rarity.

“My how interesting,” Rarity responds, walking over to the bed with a handful of clothes and laying them on the bed.

“I wonder how it would be if like oh I dunno somepony like me and you were to do something like that, who’d come out on top?” Twilight wonders aloud with a sultry expression plastered all over her face.

“O-oh I don’t know…” Rarity trails off turning into a red marshmallow.

“Maybe we should try it~” Twilight whispers into Rarity’s ear which causes her to jolt upright.

I-i don’t know darling, how would that even work,” Rarity tries to play off her heart rate increasing.

“Relax, it would just mostly be light kissing nothing more, you chicken?” Twilight taunts the marshmallow hoping to goad her into accepting.

“I am not a chicken darling and I am willing to take you on,” Rarity retorts, not letting her pride be wounded despite having some reservations on the matter.

“Alright then loser has to do what the other says then,” Twilight states azs the stakes.

“I hope you're prepared to los-” Rarity begins but is cut off as Twilight presses her lips into Rarity’s.

Leaning in, Rarity falls back onto the bed with Twilight following as the two are lip locked, with their clothed bodies pressing against each other. Their luscious melons both squish against each other moving around the soft flesh that is confined in the respective fabric as the duo begin to tongue wrestle with each other. Seeing an opening, Twilight reaches down between Rarity’s legs and slips her hand into the red laced panties to quickly begin dipping a finger or two into Rarity’s honeypot. Rarity moans in response clearly not prepared for any of this but enjoying it nonetheless, the two don’t notice however but their horns begin to slowly grow with Rarity’s stopping after about a few inches and Twilight’s continuing. Twilight felt power coursing through her body, a strange unfamiliar one but there was no mistaking it for anything else. Maybe this was the act of absorbing one's aura but she couldn’t care at the moment, she wanted to make the soft marshmallow hers. Both of them now look more demonic in appearance, and Twilight instinctively knowing she is close to victory activates her horn and spawns forth a throbbing eighteen incher and a sack of two baseball sized nuts.

Soon after Twilight flicks Rarity’s bean too much she begins to cum, clenching on the probing fingers and soaking them in her juices. She moans deeply into Twilight’s mouth as a sign of surrender, her body beginning to twitch rapidly. Twilight pulls away catching her breath and grins down at the horndog marshmallow succubus pony.

“I win… now time to claim what’s mine,” Twilight whispers into Rarity’s ear before lighting her horn up and swiftly stripping the two down to their birthday suits.
Before Rarity can respond, still gasping for air she feels Twilight pounce atop her and flip he
r like a pancake. With her face buried in the sheets and her ass up and begging to be taken, unable to resist Twilight flops her meat in between the two cheeks and begins to gently slide herself along Rarity’s crack.

“What soft ass cheeks you have here,” Twilight compliments the loser of their little game groping and kneading the plush bottom. “I can see why Spike has such a crush on you,” she teases, taking a few more thrusts between the cheeks. “Now for the main course,” she titters before cocking her hips back and using her dick like a battering ram and parting Rarity’s velvet curtains. Rarity screams towards the heavens and begins to coat Twilight’s dong in her juices and sprays all over the sheets, clenching down on the sausage that entered her cocksleeve for dear life. With a smirk Twilight begins to move her hips pulling out only to immediately slam herself back home with a meaty slap echoing, humming happily as she plows through the posh unicorn's slutty hole bludgeoning her womb.

Rarity digs her fingers into the sheets as she is constantly moaning and her ass cheeks quaking each time Twilight bottoms out inside her with the blunted horse meat dropping a fat dollop of pre cum. Twilight begins to pant heavily as she reaches and grabs Rarity’s arms pulling back to get better leverage forcing Rarity to arch her back as she then begins getting plapped even more fiercely than before her ass being turned slightly red from the sheer impacts of them. She begins to moan louder with the brutal assault upon her vaginal region by Twilight’s magic meat spear all the while Twilight has a huge lusty grin spread across her face.

Twilight soon grits her teeth while her sack begins to rapidly clench in conjunction with her rod twitching in time with her heart beat signaling the end.

“Get ready to take my load!” Twilight declares proudly, yanking Rarity’s tail to make her squeal. “The first of many you slutty slave of mine!” she booms as she focuses all her energy slowing down trading her speed for more veracity to her thrusts.

With Rarity biting her lower lip she soon cums again clamping down and spasming all over every inch of the intruder, causing Twilight to howl to the sky as her nuts began to churn and help the gooey cargo make its way through her dick veins only to erupt like molten lava deep inside Rarity’s cunt. Effortlessly painting her womb white and marking it as her territory, while oddly enough visible on her crotch as Twilight is cumming a womb tattoo resembling Twilight’s cutie mark appears on Rarity but has gone unnoticed. Grunting and heaving Twilight dumps what feels like almost a gallon or two of spooge in Rarity visibly causing her to bloat somewhat with the rest backwashing out and splattering all over her balls and lap as well as pooling on the very thoroughly stained bed sheets, who ever would wash them has quite the task ahead of them.

After a few minutes of orgasmic bliss Twilight pulls out and coats Rarity’s lower half with the rest of her load, unaware of the other change that has occurred on her. Her once feathered wings had transformed into more bat like ones with a hairless elastic skin instead of feathers. To which were proudly stretched out as Twilight was nutting in the succubus marshmallow.

“Woah when did these change?” Twilight wonders as she has now just noticed her change and looks down upon her handiwork and still erect meat rocket. She stands up and pulls Rarity to the edge of the bed and unceremoniously shoves her dick in her mouth and begins to work on her throat.

“Clean me off slut,” she orders using her magic once again to create a neat little collar with plenty of elasticity with a charm of her cutie mark around Rarity’s neck. “So adding the horns and now my wings… this must be the work of the idol,” she theorizes while Rarity only can respond with glrcks and glorps. “Well I gotta say this isn’t bad, Sweet looking wings and a harem of horny sluts doesn’t sound half bad,” she tells herself all the while noticing that Rarity too has the same wings however like her horns are slightly smaller than Twilights. “I can get use to this after all I look hot!” Twilight tells herself glancing over to a reflection of herself in the mirror and adoring her new features. “Now the question is… who should I go after next?” she wonders aloud all the while flooding Rarity’s throat with more of her succubus seed. “After all a harem needs a few more knob polishers then just one,” Twilight points out as Rarity’s eyes cross as she is filled to the brim.

Unthinkingly Twilight pulls out her now spit shined dick out of Rarity and walks over to a window looking over the entirety of Ponyville under the night sky, her gaze soon sets upon Sweet Apple Acres as well as a wicked sultry smile too.

“Maybe I’ll have a midnight snack, I am sure Applejack will sate my hunger,” Twilight states, flinging the window open and using her magic to hover Rarity to her only to hoist her up over her shoulder.

With a leap and a spreading of her wings Twilight takes flight stretching her wings and gliding through the air.

“The night is young after all,” She mentions as she makes a beeline for Sweet Apple Acres.
