Anon finds a strange book on his doorstep one night. Within it, varying cutie mark related spells were written - but one section in particular stood out. A spell that could bend a pony's mind. Though he can't understand it, he knows somepony who can.

Anon opened his door one night, greeted with a lone, mysterious book on his doorstep. Intrigued by the abstract tome, he perused the pages within. Varying spells related to cutie marks lined its aged pages, but one section in particular took him off guard.

A spell that could warp a pony's cutie mark, shifting it to a heart surrounded by chains. It would bend their mind, their life, their purpose to their assigned Master's will.

Taken aback by the entry, finding himself doubting its authenticity, Anon attempted to read it out.

Not to his surprise, he has no idea what it says - but he does know one pony who excels in cutie mark magic.

Story contains: Mind Control, lots of saucy Starlight action, casting an ancient forbidden spell, and a broken Pinkie Promise.

A New Spell

A sudden ring on his doorbell made Anon shoot up. He was just getting ready for bed, fully prepared to get some quality shuteye, before what seemed to be a visitor arrived at his home. Grumbling to himself, throwing on a pair of pants, he looked towards the clock at his bedside.

10:47 PM

Who the fuck was possibly visiting him at such a late hour? He hadn’t made any plans with any of his equine friends, so realistically there was no reason for anypony to visit him at such a late time. Mumbling under his breath, slipping into his slippers, he groggily made his way to his front door.

Grabbing the door, he pulled it open. “It’s pretty late, what can I help you with - huh?”

To his surprise, there wasn’t any pony nor any creature awaiting him. All that was before him was the empty, cool night air. Peeking his head out, he looked down the street. Dimly lit by some streetlight, he didn’t see anything out of the ordinary. Some ponies going for a late night trot, a drunk pegasus getting kicked out of a bar, and a couple erotically dressed mares that he could only assume were looking for a good time.

Sighing to himself, assuming he was the victim of a particularly annoying ding-dong-ditch, he slowly made to close his door, before something on his welcome mat caught his eye.

Laying on the ground, containing an incredibly faint glow, was a book. A puzzled look spread across his countenance, as he quickly surveyed the area around him once again. Cautiously, hoping he wasn’t walking into a cruel prank of sorts, he bent down and scooped the tome up. Realizing that it was indeed just a book, he sighed to himself. Taking a step back, he turned into his home and closed the door behind him.

Flicking on his living room light, taking a seat on his couch, Anon inspected the item he had suddenly received. Its bindings looked aged, with various gems and markings on its cover, and it felt cold to the touch. To say the book didn’t have an eerie vibe to it would be lying, but his curiosity drove him further.

Flipping open the cover, he was greeted by aged, yellowing paper. He couldn’t exactly tell how old it had to be, but from the insides alone, he had a fair hunch it was far older than any of the books he had read in his time here - and being Twilight quite literally forced him to read at times, he had a large volume of them under his belt.

Perusing through the pages, noting how it was a catalogue of ancient magics, he quickly found a trend among the spells listed. They all had to do with cutie marks, either in regards to changing them in some way, removing them, or earning them. It was an odd collection of arcane work, and frankly he never would’ve guessed cutie mark magic was so extensive.

He had a general idea of the practice, being Starlight Glimmer was easily his closest friend in this world, but even then she hadn’t spoken of even a tenth of the spells listed in here. Continuing to flip through the pages, skimming through its entries, he paused.

The following contents contain dark magic practices. The spells within this section can, and possibly will, have permanent effects.

He squinted, rereading what he just read over, before furrowing his brow. Whatever this new section was, it had taken a very sudden twist. With the mention of dark magic being thrown in, a concept he knew scarcely little about, Anon flipped to the next page.

His eyes widened a bit, as a clear image of a heart surrounded by chains greeted him. It seemed odd, being the first and only picture he had seen so far in the book’s pages, and the design itself confused him. Not sure of what exactly he was looking at, Anon read the description listed below it.

The following spell specializes in manipulating a pony's cutie mark to warp their mind, body, and soul. When the following spell is casted on a pony, its process may vary. Regardless, it will change a pony's cutie mark to the depiction shown above, and, in turn, make them entirely obedient to whomever is assigned as their Master.

His heart skipped a beat, his eyes went wide, and he felt his manhood beginning to grow excited. A part of him hoped this was legit, because sweet Celestia did it sound hot, but it seemed way too farfetched. Sure, like enslaving ponies with a cutie mark spell was a real thing in this world. He had his doubts about the book already, but now he was even more skeptical. Driven to know more, he kept reading.

The pony that has been enslaved can only be freed by their assigned Master. If their Master does not free them, or is not present, their state will last forever.

Tartarus did that sound hot to him. Keeping a pony as a constant, permanent slave? It sounded like a dream come true! A cute mare as his mindless thrall, doing whatever he asked of her without a drop of hesitation - throw in the constant, free access to pussy, and it was the best lifestyle any guy could dream of.

Still, this had to be fake. There was no possible way a spell like this could exist, it was downright impossible.

Right?

Curiosity driving him, he decided to try and read the spell. Odd, abstract language greeted him, and he struggled to even make out any letters. Yeah, he had absolutely no clue what he was looking at, not to his surprise. Grumbling to himself, still believing the insane stuff in the book had to be bullshit, he rubbed his chin.

He may not know a damn thing about magic, let alone cutie mark magic, but he does know a particular unicorn that might.

Waking up, quickly brewing and downing a cup of coffee, Anon left his home and made his way towards Twilight’s castle. With his ominous new tome tucked under his arm, he casually made his way through the town. He waved at several ponies on his way to his destination, finding himself eyeing their flanks whenever they weren’t looking.

Damn did they all look great.

He had no idea why, but ever since he ended up in this world, he had become increasingly attracted to these pastel equines. Be it their curvy forms, plump pussies, prominent assholes, abstract yet enticing tit placement, or the fact they went into heat - he just found them hot. Shame too, because none of them seemed to have the slightest interest in getting him laid. He glanced at the book under his arm.

Unless…

He shook his head, quickly dismissing the thought. Surely he wasn’t that fucked up, right? Though, having a harem of pony sex slaves did sound quite enticing…

He sighed, shaking his head again. The odds of the book being real were basically zero anyways, so there was no reason to get his increasingly fucked up thoughts going. Continuing his journey through the town, he finally arrived at his destination. He was still shocked that this castle replaced the library he had grown fond of some time ago, but alas, here was this crystal abomination in its wake. Rolling his eyes, he quickly made his way up the crystal staircase and towards the towering, heavy doors that were the castle’s entrance. Pressing on them, he pushed them open and entered her Princess of Friendship’s domain.

Empty, near cavernous walls greeted him, but that never turned him away. Though the castle seemed intimidating at first, he was more than familiar with its layout. After ending up in this world, even though she popped up quite some time after he originally did, he and Starlight Glimmer had grown rather close. He wasn't exactly sure why or how, but the two of them just clicked, and an impressively strong bond grew.

He couldn’t lie though, sometimes he wished it’d go beyond just a friendship. He spent a lot of time around the unicorn, and with that meant he had plenty of time to realize just how downright sexy she was. Her thick, juicy flanks, her plump thighs, and the lovely marehood he was occasionally blessed with the sight of - it all concocted into a horribly enticing mare.

Though, again, like every other mare, she only really saw him as a friend and nothing more. Sighing to himself, silently accepting that he was destined to never get his dick wet in this world, he traipsed through the crystal corridors, making his way to the castle’s study. More often than not, Starlight or Twilight were in there doing work of some kind, so logic only told him to head there first. Making his way to the door, he swiftly let himself inside.

As expected, with her ass unexpectedly facing towards him, Starlight was stooping down towards the ground sorting through some scrolls. He couldn’t help but find his attention darting straight to her ass. With her bent down like that, flank up in the air, Anon Jr. was already stirring in his pants. Her thick, luscious curves were shown off in stupendous fashion, her thighs looked as wonderful as ever, and he could barely see the edges of her marehood - leaving him wanting more.

He shook his head. His goal was to get some insight on the spell, not ogle the sexy specimen before him. Clearing his throat, he made his presence known. With her ear twitching, hearing him, Starlight stood up straight and wheeled around.

Raising a foreleg, she happily waved. “Oh hey Anon! Didn’t know you were coming by!”

He gave her a friendly smile, before pulling the tome out from under his arm. “I need you to look at something for me.”

Starlight read over the pages of the book, furrowing her brow. “This is definitely similar to the magic I used to work with, but something seems off about these entries…”

Having happily accepted his request to look over the mysterious spellbook, Starlight had been carefully reading through its contents. At first she seemed to look at it with a sense of familiarity, perhaps stumbling across spells she already knew, but that look soon shifted to interest and puzzlement as she got further in.

Anon glanced over at her, pointing at the book. “Trust me, just wait till you get a bit further.”

His words ignited her interest, as she began speeding up her reading. Skimming the pages, flipping through them with haste, she carefully inspected each page while maintaining a quick pace. Eventually, she got to the same warning that made him pause the night prior.

Looking at the book, she looked up at him with a perplexed expression. “Dark magic?! Where did you find this book?”

He shrugged, raising his hands innocently. “I shit you not, it just appeared on my doorstep last night.”

She looked him up and down, a hint of suspicion in her gaze, but ultimately returned her focus back to the ancient tome. Flipping further in, she eventually got to the large illustration he had seen before.

"A heart with a circle made of chains? That's something new,” she blurted out. Turning towards Anon, she raised a brow. “Have you ever seen anything like this?”

He gave her an unamused expression, nudging his head towards the book. “Do you seriously think I would know what this is?”

She rolled her eyes, turning back towards the book and reading over its text. She eventually started going over the actual spell, mumbling it under her breath. Her focus seemed to have intensified, and it honestly shocked Anon that she looked to understand it right off the bat.

Pointing at the words, he questioned her. “You can seriously understand what all that means?”

She arcanely laid the book on the near table, leaving it open on the spell's page. “The writing is a bit off, and old for sure, but yeah, I can make it out."

He was honestly shocked. He knew his friend had a sea of knowledge to her, but to quickly and easily decipher ancient texts was an impressive feat.

He looked over at the book, and then back at her. “So now what?”

She tapped her chin with a hoof, before unsurely glancing over at the tome. "I would ask Twilight about it, but she's off in Canterlot with the girls."

Anon raised his brow, having forgotten that the Elements were off in Canterlot for the next week or so. Rainbow had mentioned it briefly to him a few days ago at lunch, but he must’ve forgotten up until now. It wasn’t unlike him, after all, these ponies go on so many grand and epic adventures that it was genuinely hard to remember that they can just take normal trips.

He scratched his chin, before pointing at the book. "You think she’d know the spells in that?"

Starlight raised a brow, thinking for a moment before frowning. "Honestly, probably not. She didn't know the cutie mark magic I used when we first met, so I doubt she'd know this one. Regardless, she isn't here."

The increasingly horny lightbulb in his head went off. Eyeing his companion, drinking in her curvy ass from over her shoulder, he had a downright despicable idea. What if she tried it? What if she turned herself into a mindless slave for him to command? Or some random mare they could find waltzing around? The notion sounded enticing, though the spell still likely wasn’t real, so he wouldn’t get his hopes up - not that he’d betray his friend in such a way anyways. Regardless, his morally gray curiosity got the better of him.

"Why don't we try it?"

She whipped her head towards him, puzzled. "Did you not read the summary of the spell? It turns ponies into slaves!"

"If it works,” he replied, wagging a finger. “Plus, if it does, you'd be the first pony in who knows how long to discover and use this spell."

She recoiled a bit, seemingly thinking to herself. The notion of recovering some long forgotten magic would be an incredibly impressive feat - even with the spell being so dark and despicable. She’d certainly earn praise from Twilight, but there was also the risk of things going wrong. Still, her urge to learn and inherent knack for messing with cutie marks was pushing her towards the risky option.

Taking note that she was considering the option, the devious side of Anon intended to push her further. "You don't need Twilight to help you with everything, Glimmy. I'm sure she'd be impressed seeing you research new kinds of magic."

She bit her lip. He wasn’t wrong, Twilight likely would be impressed by her new findings - if the spell was real. Plus, if it was, then it’d mean they’d have to destroy the book, doing the nation a favor. After all, a spell that turns any and every pony it was casted on into a mindless, obedient, possibly permanent, slave was not a magic welcome in Equestria.

She looked up at him, before eyeing the book. "Well...I mean, if anything, confirming if it's real or not would be wise. It could be really dangerous in the wrong hooves."

Or hands.

He gave her a pat on the back, rubbing her soft fur. "Exactly! If it's for real, then we know we have to destroy it! Can't risk such powerful spells being out and about y'know!"

She furrowed her brow, still clearly unsure. "Well, I'd need somepony to test it on..."

Anon paused for a moment, glancing around. "Is anypony in the castle?"

She whirled her attention towards him, taken aback by just how insane his thought was. Was he expecting her to cast the spell on an innocent, defenseless pony? This spell was dangerous! It literally rewrote a pony’s mind and morphed them into whatever their Master wished for!

“Do you really think I'd cast it on just anypony? I learned my lesson the last time I messed with cutie mark magic!”

The horny little lightbulb in his head shimmered even brighter, as the devilish thought from before crossed his mind. She could easily try the spell on herself, and with it, she could very well turn herself into a slave.

“Well, why don’t you cast it on yourself?”

Eyes going wide, she stammered. “O-on myself?!”

“Yeah,” he replied, crouching down and giving her a warm smile, “what’s the worst that could happen?”

She raised her brow, looking at him with a dumbfounded expression. "Oh, I dunno...turning myself into a mindless, obedient slave doesn't exactly sound optimal now does it?"

He rolled his eyes, doing his best to provide her with comfort. "Oh c'mon, the spell says that as long as the assigned Master allows it, the enchanted pony can be freed from its effects."

She perked up, a realization dawning upon her. "But if I were to do that...then you'd have to be..."

He lightly pat her on the head, smirking. "Oh c'mon Glimmy, you act like I wouldn't let you go the second I find out it's real - if it even is."

She bit her lip, her nerves going alight as her mind raced with thoughts. Realistically, the only pony who’d be possibly willing to be the subject of such a spell would be her herself. Though, doing so would mean she’d be enthralled to Anon. She may have known the human well, and would even say he was her best friend, but the notion of belonging to someone, even for but a moment, terrified her. Still, she figured she could trust the human, he’d never doom her to a fate of being an eternal, empty-headed servant.

"You would free me, right?"

He nodded. Truth be told, he didn't have faith the spell would work, he was just having fun with the concept. Plus, she was his closest friend in this world, so he wouldn't take advantage of her like that.

At least he was trying to convince himself as such.

The horny devil in his mind was a powerful thing, and deep down he knew his libido could and would conquer his morals if the circumstances aligned themselves.

Starlight shuffled awkwardly in place, clearly nervous. "So if I cast the spell, and it works, you'll let me go right away, right?"

He doubted himself, throwing a quick glance at her rump yet again. Owning that, owning her - it sounded like a dream come true. He sighed. Even if he’d betray her in such a way, a possibility that was growing increasingly likely with every look at her ass, the spell likely didn’t really work to begin with. Taking a deep breath, controlling his rabid imagination, he patted her head

“Of course!"

She grit her teeth, tapping her hoof nervously on the floor. "You promise?"

He nods yet again. "I promise."

She eyed the tome, gulping nervously. "You really promise?"

Anon rolled his eyes, scoffing. "Starlight, cmon. Are we gonna do this all day?"

She took a deep breath, before glancing at the ominous book of forbidden magic. "W-well...for the sake of research..."

He smirked at her. "Aaaand impressing Twilight."

She smiled, chuckling lightly. It seems he managed to quell her nerves by a fair margin. She knew deep down he’d let her go, after all, they were such good friends. She couldn’t imagine any reason why he’d hold her as his slave anyways, he wasn’t some kind of villain.

She was severely underestimating the power of the human’s libido, and just how weak his moral compass was.

She took a deep breath, before giving him a calm smile. "You will let me go if it works, right?"

Anon couldn’t help but stifle a chuckle, having to go over the same promise again.

Or lie, it really depended on how things played out.

He went through the steps of a signature Pinkie Pie Promise, something he had done countless times before, and always kept. "Cross my heart. Hope to fly. Stick a cupcake in my eye."

Pinkie would kill him if she found out there's a good chance he was going to break that promise.

Starlight gulped, before levitating the book back over to her. She reads over the spell one more time, before setting the tome back onto the table.

"A-alright...here goes nothing..."

Anon watched as she paused for a moment, taking several deep breaths, before dark magic started channeling into her horn. He didn't even know she knew how to utilize dark magic, being she never had shown it off before. Twilight must've taught her a thing or two, much to his relief. No dark magic, no spell.

No spell, no curiosity, and possibly dick, being sated.

A droplet of sweat went down her forehead, as the magic in her horn intensified. "A-alright! It's starting!"

Slowly a crimson hue emanated out of her horn, purple trails forming from the corners of her eyes. The signature look of dark magic, something she was channeling intensely through her very being. She strained for a moment, looking like she may lose control of the spell, but her fortitude remained as she shrouded herself in a magical aura.

Her face contorted even more, as an intense surge of magic spewed from her horn and flew directly into her cutie mark. "Tch! O-okay, I can do this!"

Anon could only assume since she was casting the spell on herself, it was making the process in general a whole lot harder. Having your body and mind reshaped while using magic had to be rather difficult - if the spell was actually doing anything. Though, she was willingly letting this happen, meaning she was making no effort to resist the spell’s potential effects, so it should work a lot faster than on somepony who was resisting it.

As she lowered her torso a bit closer to the ground, straining even more, Anon couldn’t help but stare at her ass.

Damn that fuckable ass of hers.

He pried his eyes off her curves, knowing that right now he should be focused on her cutie mark. Looking at it, his eyes went wide. It was flashing, kind of like how Twilight and her friends' cutie marks did when they're called by the map.

A few more seconds passed, the magic around her began to pulse with energy. Surges of magic were flying into her cutie mark, and her head, at an increasing rate. Anon couldn’t help but watch on in awe, shocked by the sheer intensity of the spell. If it was real, he wasn’t surprised it seemed this grand. He could only assume reshaping a pony’s entire purpose in life to servitude would take a hefty sum of magic - even if it was the dark kind.

Starlight let her mouth fly open, her tongue lolling out as the magic around her intensified even more.

"Haaa! M-mmph!"

Anon perked up, taken off guard by the sudden moan. He couldn’t say that that was expected, but he was not complaining. Seeing the usual cute, lovable unicorn he was so close to releasing such a lewd sound - it was like music to his ears.

Not even aware that she let out a cry of pleasure mere feet in front of the human, she focused more magic into her horn. Her eyes were starting to glaze over, and her mind was growing foggier by the minute. Memories and goals were being washed away, overtaken by thoughts of servitude and obedience. Deep within her mind something told her to resist, but as she cracked an eye open and looked at Anon, something screamed within her head.

Master.

She winced, the magic she was channeling intensifying even more. Ropes upon ropes of magic funneled into her head and cutie mark. She peeked back over at him again.

Serve.

The words echoed through her mind, only encouraging her further to finalize her spell. Not only did the urge of discovery drive her, but now it simply felt right to continue the spell. Some latent, growing sensation within the shifting areas of her mind was telling her to keep going, telling her that she was not offering to use this spell on herself, but that she was ordered to. A brief moment of conflict coursed through the portions of her mind still holding their clarity - Anon had asked her to try it on herself, right? Though, that didn’t sound right to her, not anymore. He hadn’t asked her to, he had instructed her to. He was in charge, he was the one that gave her purpose.

It was good to serve, and serving meant finishing the spell.

Finalizing her own enchantment, throwing herself in both body and mind helplessly into Anon - no, her Master’s arms, that was all she cared for. With a particularly large surge of magic, she released a throaty moan, feeling her marehood becoming absolutely drenched with arousal. The spell didn't mention anything like this happening, but she couldn’t find the ability to care within her. The constant mantra of servitude was playing in her mind, drowning out any other thoughts - until eventually all that was there for her was the sensation of pleasure.

Anon hesitantly took a step forward, horribly turned on but also concerned for his friend’s safety. "Uh, Starlight? You okay?"

She didn’t give a direct response, just replying with a sea of panting and grunting. He couldn't lie, hearing her making these sounds was a carnal symphony of delight, and the concern he had for her was quickly washing away. He wanted to hear more. He wanted to see where this would go.

"B-buck...! S-sooo good!"

Her eyes started rolling back, and she bit down on her lip. It was becoming even harder to focus, all her thoughts morphing to pleasure, bliss, obedience, and Anon.

He stared at her face, utterly bewildered, until movement on her behind caught his attention. Whipping his head to the side, he saw that her tail was starting to flick.

“No way,” he said out loud.

He quickly moved to the side, scrambling towards the other end of the room and positioning himself behind her. As if the gods decided to bless him with their grace, he watched as her tail fully flagged itself. His eyes went wide as dinner plates, as he was greeted with the clear sight of her dripping, and wantonly winking, marehood.

He couldn’t speak, he couldn't even think, as he looked on at literally the hottest thing he’d ever seen. Either she had a penchant for dark magic, or this spell had some very arousing side effects. Both for the pony affected and for the devious human spectating.

It was only getting better, as she was starting to buck her hips back, her ass swinging towards him with every single motion. The magic around her was shining even brighter. Her juices gushed out of her cunt, coating the crystal floor in wondrous splashes of pure arousal. The aroma of raspberry mixed with vanilla met his sinuses, making the insides of his nostrils tingle like he sniffed something spicy. She arched her back, lowering her torso but keeping her flank in the air, still bucking back. Her marehood was winking intensely, opening her slick folds every few moments as she let out moan after moan of pure pleasure.

Anon was frozen in place, feeling his groin begin to ache as Anon Jr. was very much so awake now. Unbuttoning his pants, he slowly slipped his hand into his underwear. He just couldn’t resist the urge, the spectacle before him simply too hot to possibly resist.

With an intense surge, before he could even start stroking himself, the aura around Starlight exploded outwards. In a flash of light, Anon blinded, taking a few steps back as he was in a world of pure unending white. Starlight’s moans stopped, as he tripped over a book on the floor and fell back on his ass. Clenching his eyes shut, it took several moments before the powerful glow faded. Waiting several movements, ensuring it was safe to look, he opened his eyes and waited as his vision slowly cleared.

He took a moment to look around, spots dotting his vision, but soon found his gaze locked in place. Laying before him, in a massive puddle of her own juices, was Starlight. She must've came from the spell, as her cunt was slick with her climatic juices, still winking all the while. Even her asshole was throbbing, pulsing with a need she never even knew she had in her.

As lovely as the sight was, literally the best thing he could possibly imagine, he had to make sure of something.

He looked at her flank.

To his subconscious glee, there it was. Rather than the familiar cutie mark he always saw on her, there was a heart surrounded by chains.

Holy shit. The spell actually worked.

He sat still for several moments, staring at the pony before him. She wasn’t moving besides the slow rise and fall of her chest, a frequent wink of her pussy, and the occasional twitch of her tail.

"H-hey Starlight...you there?"

Her ear twitched. Anon watched as she stirred a bit, her legs and head moving ever so slightly, before she suddenly and slowly rolled onto her stomach. Her eyes were shut, which seemed a bit odd, but Anon didn’t have much time to ponder on it. After a few more seconds, she shakily rose up onto her legs again. Standing upright again, leaning back in forth as if she was drunk, Starlight faced away from the human, her tail twitching wildly behind her.

Several agonizingly long moments passed, as the two stood in silence. Anon had a endless sea of thoughts running through his head, mixtures of good scenarios, bad scenarios, and all the like. Finally, as if to quench his anxiety, she turned towards him and opened her eyes.

They had fucking hearts in them.

The second she saw him, her tail flagged itself fully.

"Hello, Master~"

He was frozen in place, awestruck from what he just heard. There were hearts in her eyes, she flagged her tail the second she saw him, and she just called him Master.

His mind was racing, his breath was locked in his lungs, and he blinked wildly in disbelief.

She called him Master.

He gulped nervously, unsure of how to speak to her. “U-uh...hey Starlight, how...how are you?"

She simply smiled at him. "I am well, Master. How may I serve you?"

Anon gulped again. Was this really happening? Was this real life? Could if be, by some otherworldly power, she now belonged to him. With his arousal soaring to new heights, and only having one real option to figure out if this was real, he opted to test things out.

"You'll do anything I say?"

She perked up, her smile never fading. "Of course, Master. I exist to serve you."

He took a sharp breath, thinking to himself. Jumping the gun to something insane could be reckless, both if this was real or not, so why not start with something subtle.

"Uh, okay. Hmm...bark like a dog."

She immediately gave a hearty woof in response, her tail fidgeting a bit behind her.

Anon looked on in disbelief, struggling to grasp the situation. He had to test her more.

"Spin in a circle."

She did so without question, her tail flicking more once she finished the command.

Anon paused, eyeing her tail. Did obeying him turn her on? It only was moving like that after she followed one of his commands, so it didn’t seem too farfetched of a concept. Seeing how she was listening to him, Anon’s confidence began to grow.

"Starlight, does listening to me excite you?"

She slowly swayed her hips, looking right at him. "Yes it does, Master. Unless you don't want it to."

Hearing that come out of her mouth, in her voice, as she swayed her hips like an absolute slut - it nearly made Anon’s knees give out. It was hot. She was hot. This was way too hot. Where the hell did the spell mention that it makes the pony horny when they obey you?

A part of him was glad it didn't say it, because it would've definitely made Starlight reject his original proposition.

He felt his balls begin to ache, his arousal reaching impossible levels. "No, that's...that's good. How excited are you?"

She tilted her head. "Would you like me to show you, Master?"

He wasn’t entirely sure what she meant by that, but sure why not. He didn’t see much harm in it, and he knew finding out would only make the situation even hotter than it already was.

"Yeah, go ahead and show me.”

Nodding her head in understanding, Starlight bowed her head and spun around. With her rear facing him, showing off her glistening pussy and pulsing pucker, she lowered her torso, keeping her ass in the air, and ignited her horn. Magic shrouded her nethers, as she arcanely spread apart her drooling lower lips right in front of him.

"I'm this excited!" she chirped.

Anon Jr. is quite literally fighting for his life right now.

He had never been more turned on in his life. No amount of porn, fantasies, or wet dreams could even come close to how downright exhilarating the scene before him was. He glanced at his crotch, seeing Anon Jr.'s struggle with his own eyes.

He looked back up at his slave, beginning to yield to that desire he knew would come in the end. "You'll do anything to please me, right?"

She glanced back at him, still holding her scandalous position. "Of course, I exist to serve."

He was pretty sure he wasn’t gonna keep that Pinkie Pie Promise. Glancing between Starlight and his crotch, he couldn’t help but start giving in more and more to his downright need.

"You'll really do ANYTHING I say?"

She swayed her hips, stopping her magic as she finished spreading her winking marehood. "Yes, Master. You own me."

He gulped, feeling his cock twitch in his pants. "A...alright, then..."

He hesitated. She was his friend, right? He promised he’d let her go right away. She put her trust in him, believing and having faith that he wouldn’t take advantage of her. She took a massive risk, possibly throwing her free will away forever for the sake of research, all because she believed in him.

He eyed her, gazing at the glorious sight of her happily presenting herself before him. Her pussy gave a particularly enthusiastic wink, a line of her nectar dripping out of her slavering folds and down her inner thigh.

Yeah, no, he couldn't resist the temptation.

His mind raced, knowing full well he was going to betray her trust. She was just too hot, and the opportunity to finally get some real sexual stimulation was too good to pass up. He could have a little bit of fun with her, and then let her go. He just had to hope she wouldn't remember any of this.

Quickly he fumbled with his pants, throwing them off. There was Anon Jr. standing at attention. He looked over at the mind controlled pony, watching as she continued to sway her hips seductively, looking back at him with those beautiful hearts in her eyes.

Caving to his need, throwing away any sense of morality he had, Anon gave her a command. "S-Starlight, come suck my cock."

Without a single ounce of hesitation, she rose back up, turned around, and trotted over to him. Unready for how fast she reacted, Anon scrambled to grab a chair, pulling it over and sitting back in it. He watched as she waltzed up to him, staring right at him the whole while.

Pausing mere feet from him, she smiled at him warmly. "Of course Master, whatever you demand."

He swore to Celestia, his heart was about to burst out of his chest. This was happening? This was really happening? She stooped down, leveling her muzzle with the head of his cock.

He still had doubts this was real.

Slowly she parted her lips, letting her tongue crawl out of her maw.

This was totally a dream, right?

She lowered herself a bit more, her hot breath clashing against his stiff member.

This just couldn’t be real. It was too good to be true.

She lowered herself more, gingerly engulfing his cock into her mouth. Her tongue bathed the underside of his manhood, as she pressed her muzzle further, bringing more and more of his dick into her mouth. His entire body stiffened, the warm and wet sensation of her mouth overwhelming him.

Holy fuck this was really real.

She slowly began bobbing her head up and down, taking half his cock into her mouth with each motion. Caressing his tip with her tongue on every rise, and dragging it along the underside of his dick with each bob downwards.

He felt his legs quivering, the only thing his mind registering was that he wanted more. "F-fuck...g-go all the way..."

He watched as she paused for a moment, looking up at him.

"Yesh Mahster~"

She threw her muzzle downwards, engulfing the entirety of his manhood into her maw. His cock slipped down her throat, and he heard her moan around his tool. Anon was pretty damn impressive in terms of size, rivaling even some of the most well-hung stallions around, yet she began throating him like a seasoned whore.

She began bobbing her head up and down again, her tempo increasing gradually as she serviced him. To say she felt great would be an understatement - no, she felt divine. She was going all out now, taking his entire cock in rapid succession.

He was seriously beginning to doubt if he’d let her go.

Ever since he ended up in this world, Anon had gone without any sexual gratification from the colorful inhabitants here - but now, he quite literally had one worshipping him with every fiber of her existence.

He grimaced, feeling himself quickly approaching a climax. She was sucking his cock with passion, working her mouth to its limits to serve him to her greatest ability.

"Glk! Glk! Glk!"

The sounds of her slurping on his cock were only helping him rapidly approach his limit. The combination of how the spell made her look, the fact she was now nothing more than a puppet for him to control, and the feeling of her deepthroating him- it was all too much to bear.

Gritting his teeth, he grabbed the back of her head, forcing her head down as he thrusted up into her. He was quite literally facefucking her with everything he had. Taking some initiative, feeling his cock flaring in her mouth, Starlight ignited her horn with magic. He winced as he felt a tingling sensation on his balls. An aura shrouded them, as she began massaging his nuts with her magic.

The pleasure he was enduring had now surpassed his wildest dreams. Thrusting his hips, slamming himself into her face, he felt his balls pull up to his groin. His climax reaches him with cataclysmic force. Barely holding onto reason, waves of unending pleasure coursing through his very being, Anon managed to stutter out a command for his slave.

"S-swallow it all!"

She mumbled around his cock, as the first ropes of his semen spewed out of his cock. Molten, thick cum shot into her mouth, and she eagerly began swallowing every drop she could get. To her, this was what she was made for, what she lived for. Serving her Master, being used as a tool for his pleasure, that was happiness. That was pure bliss. Nothing of her past life mattered, the pony she once thought she was now a bitter memory. Her mind had been reshaped as her will was reformed into an empty husk for Anon to bend.

Anon slowly rocked his hips, pushing his cock in and out of her throat as he rode out his orgasm. She was still happily swallowing the essence that he was gracing her with, wagging her tail all the while. Eventually, shaking intensely, he reached the end of his blissful journey of lewd euphoria.

Starlight continued sucking his cock, fulfilling her order out regardless of the circumstances. His cum tasted phenomenal, and the feeling of fulfilling her sole reason to exist felt even better. He breathed heavily above her, catching his breath. Fending off the pleasure of her continued service, he looked down at her.

"Sta - ah fuck...Starlight."

Her ears twitched, hearing her Master call her name. She continued blowing him, waiting for her next order. She’d dutifully obey, it was all she knew.

"Starlight, stop sucking my cock."

She immediately complied, pulling her head back and releasing his cock from her maw. A trail of saliva connected her tongue to his dick, as she panted lightly and looked up at him.

Tilting her head, she looked up at him. "What would you like now, Master?"

He stopped for a moment, conflicted. It was true, if he let her go he’d likely never get his dick wet by one of these equines again. He couldn't give this up, it was just too good. True she was his friend, but his endless libido conquered all. She made for a great sex slave.

His sex slave.

He eyed her, the devious thoughts in his mind overpowering those that told him to let her go. "You're my slave, isn't that right?"

She nodded. "Yes, Master."

He took a deep breath, preparing to cement her new status for the rest of her life. "And we're gonna keep it that way."

He was met by a massive, ear to ear smile, as Starlight was beyond happy to hear his confirmation.

"Thank you Master! I'm so happy to serve you forever! What do you wish to do next?"

He paused for a moment, thinking to himself. There were a multitude of things to handle, plans to be made, and lewd pleasures to indulge in. A few minutes pass, until he came across a particular idea and he was barely able to hold on a devilish smile.

He never really saw himself as a bad guy, but with what he was scheming, he was definitely shaping up to be one. He felt his cock beginning to grow erect again, as a devious thought crossed his mind. He wasn’t sure if this newfound power dynamic was warping him, or maybe deep down he was a devious degenerate with a disregard for morals all along. Either way, he liked the idea he was brewing in his head.

Why stop at just having one slave? The way he saw it, he could build a harem of mindless, eager pony sex slaves. Starlight would just be the key player in this lewd game. This world denied him any true pleasures, seemingly because all the ponies here saw him as only a friend and nothing more.

He’d show them what true pleasure was.

He quickly threw on his pants again, though he figured they wouldn't be staying on for long. Not with the sexy mare that now existed to serve him mere feet away. Looking at Starlight, he walked up to his new slave - his former friend made fucktoy.

He looked into her eyes, hearts looking back into his. A bit of sweat was beading down her face, which must’ve been from the effort she exerted when she was milking his cock dry. Chuckling to himself, realizing he finally had one of the mares he craved for all to himself, he affectionately stroked her mane.

“Would you want other ponies to experience the joy of serving me, slave?”

She bit her lip, shivering as he guided his hand along her back, rested it on her cutie mark, and gripped her ass. "Yessss Master ~ I'd love to show more ponies the bliss of servitude."

He chuckled, gripping her ass a bit harder, reminding himself he’d be sure to fuck her sensless later. "Good girl. You're making Master very happy."

Her tail started wagging, as she gave him a massive smile. "I'm glad, Master! I live to please!"

Snickering to himself, he ruffled her mane, showing his toy a bit of affection. "That you do, and I gotta say, you're already proving to be very good at it."

She pressed her head against his palm, nuzzling him. She was just as cute as she was sexy. "So Master, how do we claim more mares for you?”

He paused, realizing he hadn't thought that out yet. He couldn't go out in public, not with her like this, her cutie mark would be a dead giveaway that something was up.

He tapped his chin, thinking to himself. Just how exactly was he going to roam around outside with her like this? How was he going to add more mares to his collection? He glanced over towards the book, nearly facepalming.

That was the key.

His thought process was interrupted, as a voice called out from near the castle’s entrance.

"Princess Twilight? Starlight Glimmer? It's me, Mayor Mare! I'm here with those permits you asked me to get for you! Hello?"

Welp, time to get the answer to one of his questions at least.

He turned towards Starlight, raising his eyebrows as he gave her a cheeky smile.

“You can use that slave spell again, right?”

She licked her lips, looking at him with lidded eyes, as she began connecting the dots he was laying out for her.

“Of course Master, and I think your next fucktoy just made herself known~”
