My Existence, the Greatest Perversion.

Contrary to popular belief, Princess Twilight Sparkle couldn’t read books forever.

Oh, reading was her favorite hobby. A good book and a nice cup of tea or mug of hot chocolate and she was golden most days.

However, there was a special sort of frustration that came with looking through book after book for days on end and not finding the one bit of information she was looking for that could make even the most ardent of bookworms swear the damned things off forever.

That was Twilight’s present predicament.

To her left, three stacks of books, all read, nearly reaching to the ceiling of her old Canterlot abode – which hadn’t been taken up by a new pony, to Twilight’s surprise – and to her right, three stacks of books she’d yet to read, also nearly reaching to the ceiling. Twilight had been surprised beyond measure that there were no books specifically on the subject on spermavores, but that didn’t stop her from going through every tome on monsters, Equestrian lore, black magics, and all other subjects even peripherally related to the topic. What little she could find was that they were related in some ways to vamponies and succubi, products of wicked sorcery and demonic ritual, and that mares who had been changed had their entire internal structure changed dramatically to accommodate their new thirst.

That was it. Thousands upon thousands of books, days poring through line after line of ancient text, and all the information she could find on spermavores amounted to one sentence that she already knew. It was enough to make a pony scream. And so, that’s what Twilight did. Unfortunately, she still hadn’t quite mastered screaming in her new ailicorn body. The stacks of books shook violently from the sheer force of the Royal Canterlot Voice, the fine porcelain that had held her lunch cracked, and even the enchanted panoramic glass before her started to vibrate threateningly.

Still, that was at least somewhat cathartic. Frustrated, Twilight closed her latest completed book and started a fourth “read” stack. Looking at all the books she’d read, then all the books she needed to get through, Twilight came to a conclusion that, while perfectly acceptable from other ponies, sounded odd coming from Twilight Sparkle’s lips. “I need a break,” she groused, blinking several times to soothe her dry eyes.

“You do.”

Twilight suddenly shot upright, looking toward the entrance. There stood Princess Celestia, looking at her with a soft frown and a tremble in her eyes. “You’ve been at it for days without rest, Twilight,” Celestia softly admonished her beloved. “You can’t continue to push yourself this hard.”

“But I have to!” Twilight protested, willing tired, sore legs to walk around the book stacks and toward Celestia. “I have to find something that’ll help Rarity.”

The Princess of the Day raised an eyebrow, then folded her legs to look at Twilight at eye level. “Rarity?” she asked. “What’s wrong with her?”

“She’s gone!” Twilight cried. “She just up and left last week. Said nothing to any of us, just sent Applejack a farewell letter and vanished.”

“Why would she do that?” Also contrary to popular belief, Princess Celestia couldn’t retain perfect composure at all times. She wasn’t in hysterics like Twilight, but the tight frown and narrowing of her eyes told of worry matching the rest of Twilight’s friends. “She’s not been failing at her business, has she?”

Twilight simply shook her head. “No, that’s not it at all,” she said. “She’s got some sort of condition, and I’m trying to find something that can help her while the others try to get her home.”

Celestia sighed, looking down at the floor. “So, they weren’t able to contain it.”

“Wait...” Twilight blinked at her a few times in surprise. “You know about it?”

“Her being a spermavore, yes,” Celestia admitted, looking up to her student again. “I had commissioned a group of clerics look into Rarity’s condition as soon as she was turned... But they never had good news for me about the treatments, even after she moved here...”

Again, Twilight was flabbergasted. “How long has she been a spermavore!?” the purple pony asked, wide-eyed in shock.

“Since about a week after she’d gotten her cutie mark, from what I understand,” Celestia replied darkly. “If you’ll allow me a moment to tell you what happened, at least as I understand it...”

–

Rarity pranced gaily on her way to class. Still elated at her new cutie mark, a smile nearly the width of her face greeted every pony she passed by, most of whom congratulated her on her finally reaching that sacred moment of marehood.

Of course, even a week after her special day and her resulting Cuteceñera, she had to deal with bullies. One of which she was passing by right at that moment.

“Hey, look, it’s the diamond diva!” A young brown unicorn stallion with a black mane and tail sneered at the newly marked mare as he leaned against a wall.. “So what now, ‘darling’? Going to go work in a diamond mine?” He patted the imposing-looking wand on his flank, a large crimson orb atop it. “Too bad you couldn’t get a cool cutie mark like me!”

“Hmph!” Rarity tossed her delicately styled hair as she turned her face away from the brute, not even losing a hint of the spring in her step as she walked by. “Hardly, my dear Crimson Scepter!” she replied. “I’m going to make the most beautiful dresses in Equestria!”

Crimson snickered at Rarity and let out a chuckle. “Really, who’d want something made from a frigid little pony like you?”

**That* set Rarity off. “Frigid!?” She stopped in her tracks and spun around to meet the bully head-on. “Just because I won’t reduce myself to your base level doesn’t make me frigid! As if any lady would ever lower her standards as to date smelly brutes with nothing better to do than harass students in the hall!”*

“Lady...” Crimson nodded, a wry smile on his face as he rolled the word on his tongue as if trying to discern its taste. “We’ll see about ‘lady’ soon enough...”

At that, Rarity felt something hard smack her in the back of the head. The last thing she saw before passing out was Crimson nodding to whoever it was that had attacked her.

–

Rarity awoke to a dark, cold, foreign room of unpainted red bricks, her horn adorned by a large, golden inhibitor ring which was itself adorned with a sparkling diamond, her legs chained to a cold, steel slab, lewdly displaying her unmentionables to the four stallions room. Even in the dim candlelight, she could make out her four captors quite easily. She recognized them all from school; rather boorish characters who had spent the last couple of years alternating between trying to have sex with her and harassing her about her about her love of high fashion and whatever other sore spot they could find, but all especially adept in the magical arts.

In front of her was Crimson Scepter, looming over her with a maniacal grin on his face. To his left was Emerald Blade, a dark green unicorn stallion with a lighter green mane and tail, sporting a halberd for a cutie mark. To his right were a pair of red unicorn stallions, one with a white mane and tail, and the other with a matching black, called White Hat and Black Hat respectively, both sporting pointy wizard hats for cutie marks.

“Rise and shine,” Crimson growled softly. “Rise and shine.”

Rarity gulped as she looked at the four, who were now circling her with malice in their eyes, Crimson at the front of the slab, staring directly at Rarity’s pussy with a hard, cold gaze. “What is the meaning of this!?” she shouted indignantly. “You let me go this instant, you ruffians!”

The brothers Hat snickered, while Emerald reached over to make sure the inhibitor ring was secure. Crimson remained still, levitating a book over to him and turning over the pages. “By the time we’re done with you,” he declared, “You won’t be able to keep your hooves off us...”

Rarity huffed at that. “Hardly!” Even trembling in fear, Rarity maintained a stiff upper lip and a hard, defiant stare. “Even if you lot were the last ponies in the world, I’d never touch you!”

“Let’s see about that....” As Crimson spoke, he passed around the book to the other three, all of them taking turns looking at whatever it was Crimson had brought to their attention. “You guys have memorized the spell, yes?”

“Of course,” Emerald replied. “Like I’d ever mess up my chance at putting this snooty bitch in her place!” The other two grunted in the affirmative as well, nodding their readiness at Crimson.

Satisfied with his friends’ responses, Crimson nodded slowly. “Very well, then,” he said. “Let’s begin.”

The light of four horns joined the dim candlelight as the four stallions started to pool their magical energies. Even knowing how gifted they were, Rarity gulped nervously as she felt the oppressive force of their magical energy put together. Her bluster quickly fading, she bit her lower lip and started to struggle against the chains. Feebly, she tried to summon her own magic, but the inhibitor ring did its job, rendering her magic completely inert. The fear inside her began to build, morphing into panic as her heart began to thump wildly in her chest. She opened her mouth to scream, but could scarcely make a sound over her own hyperventilation.

Then came the chanting. It wasn’t in Equestrian, of that much she was certain. Part of her was convinced it wasn’t of anything any pony would recognize, all sharp syllables and throaty grunts, the sort of language that might be found in the very depths of Tartarus, spoken among monsters as they schemed their wicked endeavors. Eventually, the magic of the four stallions formed itself into a giant, sphere of energy, strange runes shining in the orb as the chanting continued. Again, Rarity tried to scream, and again, her body betrayed her.

The ball lowered itself toward her, and she continued to struggle wildly against the metal bonds. They would not yield even slightly, keeping her firmly in place as the energy drew closer.

Then, it enveloped her, and the pain came. Rarity had never been one to take pain very will, but this, she was convinced, would break even the strongest ponies. Fire burned inside of her, organs and blood vessels pulled from their moorings, shifting around as would a litter of kittens trying to find a comfortable sleeping spot. She could feel some of them coming together, and others still being burned to nothingness inside her, as though swept aside by the cruel, unseen sculptor reshaping her just beneath the skin.

The pain still remained, strong as ever, as she passed out, and for a moment, she was convinced she would never awaken. What little part of her that could still think wondered if waking up would be worse.

–

The mare awoke, starving and dizzy, in a strange, dimly lit room, surrounded by four stallions. Four horny stallions packed with seed, if her nose was right. She sat upright and looked around, noticing the hard cocks they were all sporting. One of them approached her, a brown unicorn with a black mane and tail.

“Now, Rarity,” he said firmly. “Get on the floor.”

Rarity? Was her name Rarity? She couldn’t remember that name... She couldn’t remember anything. Her mind was blank, save for the burning desire to feed. Was this her first time? Her fiftieth? She didn’t know. All she knew was that one of the stallions told her to get on the floor. Maybe if she did what she was told, they’d let her feed on them. Sliding off the metal slab and onto the cool brick floor, she sauntered over to the one that had commanded her, her tail up in the air to show herself off to the others.

“Looks like it worked, Crimson!” another of them said. “An extra cunt instead of an asshole, just like the book said.”

The brown stallion licked his lips at those words. “Good.” He then looked at the mare with a gaze that spoke of its own hunger. “And it looks like you’re nice and obedient now, slut. Spread your legs. All four of them. As wide as you can while still standing.”

She did as she was told, and saw another of the stallions, a red unicorn with a white mane, slide underneath her, careful not to kick her legs out from under her with his own. It was then that she felt it – a cock, entering one of her pussies. It was hard, long and thick, pulsating with life-giving seed. She barely had enough time to get used to the fullness when the other red stallion mounted her from above and shoved his length down her other pussy. She let out a throaty moan of pure delight. The two cocks inside her were pulsating, throbbing with life, just ready to pump her full of what her body desperately needed.

In front of her, the green and brown stallions looked at the spectacle before them, both of them smirking triumphantly.

“Not a lot of room for us to get in there,” the green one said.

“No, but what’s the rush?” his brown friend replied, his grin nearly as wide as his face. “She’s going to be in a frenzy for a while. I say we have turns fucking the bitch.” He licked his lips and stared intently as the tangled trio of ponies. “Besides, watching can be fun too.”

The two that weren’t in on the action yet simply found a place to sit, watching intently as the two red stallions began to pump their cocks in and out of the mare’s sopping wet, greedy pussies. Her moans filled the air as the two of them rammed their dicks balls-deep inside her hungry body, her eyes fluttering violently with each heavenly penetration. As they took her, the mare bucked her hips back and forth wildly, squealing her delight as she was ravaged by the two powerful stallions. They’d kept at it for a while, grunting and groaning their lust as they drove into her as they fucked her relentlessly. Then, it came. Or rather, they came. At once, the two stallions unloaded inside her, cocks throbbing uncontrollably as they packed her core full of the semen she desperately needed. Driven by the sudden influx of seed, the mare squealed as her own orgasm hit her, sending her body into uncontrollable shivers.

The three partners stayed there for a moment, perfectly still as the two red stallions emptied their loads into her needy snatches. When they finally pulled out, she could feel the hunger still gnawing at her. She saw the other two and slowly walked over to them, licking her lips as she approached the two cum-fountains.

“Looks like our turn,” the green one said.

“Well,” the brown one replied, “Let’s not keep her waiting...

Unlike before, neither of them slid underneath her. Instead, the green one mounted her from behind, slipping into her lower pussy, which was now gushing wet with juices. The brown one took an interest in her mouth, maneuvering around his green friend to shove his dick down her throat. Both filled her gloriously, and she sucked eagerly on the one on her mouth as the two of them began to pump wildly, driving themselves into her with the same force that their red friends had done earlier. All the while, the two of them couldn’t stop laughing, occasionally slapping parts of her with their hooves.

“This bitch is so fuckin’ easy now!” one of them said. She couldn’t tell which one, with her vision obscured by the brown one’s groin. Not that she cared.

Her world was just these two stallions, their rods practically bursting full of semen as she sucked wildly, moaning and whimpering hungrily as she slurped desperately. All the while, all she could think about was the semen. She needed it with every fiber of her being. Her body and soul cried out for it, and she would do anything to have more.

The two stallions eventually let out grunts as they came, and her throat and pussy both clenched around them, eagerly drinking the load that the stallions generously gave her. She was in heaven, sucking cum from the front while she was filled from the back.

However, heaven was short-lived. As the two of them pulled out, she could feel the hunger once more. Would she *ever** be sated? Looking around at the four still-horny stallions, she licked her lips, her eyes wide and trembling as she cooed softly. “More...”*

–

“The faculty found her a week after that, and it took yet another week to bring her down from the mania enough to even remember who she was,” Princess Celestia said, visibly shaking with disgust. “After that, the perpetrators were brought here, while I sent a team of clerics to help Rarity’s family.”

Twilight simply sat there, mouth slightly agape at the story she had just heard. It had, as she expected, been horrible beyond measure. “So... What happened after that?”

Celestia’s eyes hardened at that question. “The four stallions were sentenced to ten years of forced magic inhibition. I believe the enchantment on their rings ends this year. As for Rarity, well... Like I said, I never got good news.”

Twilight gulped nervously. Part of her was not sure she wanted to ask, but the question just wouldn’t go away. “What... What did they say?”

Sighing, Celestia shook her head. “Since she was young when she was turned, it would slowly take her over as she matured. First, she’d need weekly feeding, then bi-weekly, getting more and more restrictive until she reached peak maturity, where she would be truly immortal, but...” She shook her head and gritted her teeth. “... But she would need feeding twice a day, or more, lest the mania return.”

“Or more!?” The idea that one even had time for more than two sex sessions a day was insane to Twilight. How would a mare have any time to work, to play... To live?

That was when it hit her. “So, that’s why she closed her business and went to do porn...”

“I’m surprised she even tried fighting it,” Celestia admitted. “It’s a terrible dark magic and, unfortunately, completely irreversible.”

“S... So there’s nothing we can do?” Twilight asked, screwing her eyes shut to hold back the tears. “What... What about Applejack?”

Silence reigned for a moment, then a sigh from the elder Princess. “... I’m sorry, Twilight. At least she’s better off than the others...”

“Others?” Twilight was surprised there were others, but if there was anything that could help Rarity at least adjust, she was willing to try.

As if sensing what Twilight was hoping for, Celestia shook her head. “They were products of dark magic, created as sex slaves to unicorn kings, long before even the time of Princess Platinum. From what I understand, about three hundred of them were made before Rarity. They’re all aimless vagrants now, using their pheromones to get their next ‘hit’ off of anything they can get to shove cocks inside them. In many ways, Rarity’s lucky to have been turned in a time of video porn...”

Her last hope dashed, Twilight simply hung her head low. “So that’s it?” she asked, voice soft as she tried to come to terms with such a crushing defeat.

Celestia simply sat beside Twilight, draping a wing over the young ailicorn as she pondered Rarity’s situation. Certainly nothing could be done to save the alabaster unicorn from her fate, but if even one thing could be done to comfort her, to give her at least some measure of happiness beyond the base needs of her species, it was at least worth considering. “Tell me, Twilight,” Celestia began, carefully choosing her words, “would Applejack do anything for Rarity?”

“O-of course!” Twilight exclaimed. “I’ve never seen two ponies love each other like Applejack and Rarity!”

Nodding, Celestia took a deep breath. “Then, listen to every word I have to say. If Rarity and Applejack are to have any future, it won’t be without sacrifice...”

–

The train ride had been long and, in many ways, tedious, but it was finally over, and now that they were in Los Pegasus, they were able to start looking.

Deciding that it’d be best to split up, Pinkie and Fluttershy started pounding the pavement, asking people on the street if they’d seen Rarity. Applejack and Rainbow Dash, meanwhile, thought it’d be a good idea to peruse the adult novelty shops all over the place. It was in one such store that they were having a discussion.

“So,” Rainbow Dash murmured as she hovered just above the ground, looking at the various videos showing mares of all sorts in very compromising positions, “You never noticed she had an extra one?”

“No!” Applejack exclaimed. “I didn’t go lookin’. I dunno about you, but I don’t find anything interestin’ about tail holes!”

“You haven’t lived then,” Rainbow quipped. “Extra tight, not a lot of give, feels great when its being pried open...”

Applejack rolled her eyes. “Oh, spare me,” she sighed, before looking around the aisles again. “So, tell me why we’re not just asking people like Pinkie and Fluttershy?”

“Really?” Rainbow deadpanned. “Way I see it, if she’s doing porn, we could either find a video with information on the company she’s working for, or if that fails, ask the guy at the counter about up and coming talent. That way, we can narrow our search.”

A grunt escaped Applejack’s lips as she looked at a particular one titled Gem Cave VS the Diamond Dongs! “Well, I guess there’s that... Still, she’s only been here, what, a week and a half? Maybe two? How’s she gonna be in... Woah...” She looked intently at the cover for a moment, eyes narrowing. “Holy moly...”

Intrigued, Rainbow Dash flew over to Applejack and took a look. “Yeah.... Holy moly is right...”

The cover sported a trio of diamond dogs, all erect, as a white mare with a gorgeously curled mane and tail worked on them, hooves wrapped around the cocks of the two dogs on the sides while her face was bobbing along the length of the middle. The mare’s flank clearly displayed her cutie mark – three blue diamonds.

Both Rainbow Dash and Applejack had come to the same conclusion. “Rarity...”
