Flux trotted into the Cloudominium, making sure to close the large double doors behind him. Grumbling to himself, lost in thought, he glanced over at a mirror to his side. Greeting him wasn’t his usual unicorn self, but rather a dark blue pegasus, leading him to roll his eyes.

“This Changeling magic always creeps me out,” he mumbled to himself, soon beginning to channel magic in his horn.

Shrouding himself in a green aura, he felt his body tingle as a transformation occurred. Clenching his eyes, finding the sensations this spell offered highly uncomfortable, he awaited for it to run its course. Shivering in place, feeling the last remnants of the arcane force leave him, he slowly opened his eyes. Looking back at the mirror, he was greeted with the familiar visage of his normal self.

“And it sure as fuck feels weird.” he continued, tossing his belongings onto a nearby table.

Some time had passed since he had broken Rainbow Dash, morphing her defiance and ego to subservience and desire, and during this time many changes had occurred. The primary one being his location. With Manehattan’s law enforcement restructured, which meant Flux’s base of operations would more than likely be besieged, a relocation was necessary. Though it seemed like a gargantuan task at first, he soon found his answer in his new toy.

He was aware that Rainbow had quite the large home, and being she was his loyal, little fucktoy, the answer to his problem came on a silver platter. He had told her he wished to move into her home with her under the explanation that he was her new coltfriend - of course meaning he’d be disguising himself as to not be recognized by anypony. At first he assumed he’d have to make use of Devotionis Vestigium, in regards to her having to obey his orders, but she had eagerly jumped on the proposition the moment he suggested it. She quite literally needed him, and was addicted to him in every way, so the prospect of having her Master’s cock on a daily basis sold her on the idea within seconds.

Besides relocating to her home in Ponyville, Flux had also spent his days mastering the spells within his arcane tome. Focusing on the ones that were essential to Rainbow’s downfall, he elevated their potency and efficiency by an incredibly large margin. Infinitus Calor had the most drastic change of them all. It had taken several weeks of the spell’s effects to bring Rainbow down, but now one blast from it was nearly as strong as a dozen or so back to back. The mind warping spells he had at his disposal weren’t all too different, only increasing in the speed at which they take effect - an effect he had tested on Rainbow several times in the past few days.

As of late, now that things had died down a bit, he found himself often pondering about the future. Sure, having Rainbow Dash as a slave was a fantastic development, but he couldn’t help but feel he could be doing more. With all this newfound power he had, coupled with the fact that he was only growing stronger as the days went by, he couldn’t help but wonder - why stop at only Rainbow?

Realistically, he could probably bring any mare to their knees with enough effort, bar the Princesses, but he just wasn’t sure who to target. There were countless females to bed in all of Equus, pony or not, but he didn’t want to amass too large of a harem. Rubbing his head in annoyance, frustrated with himself for lacking the ability to pinpoint a direct set of targets, he locked the front door of the home behind him.

Trotting through the home, mumbling to himself in thought and carefully laying his tome on a stand near the living room, a particular sound caught his attention. Turning towards the stairs, he smirked as the unmistakable sound of Rainbow fervently attempting to tame the carnal need within her reverberated through the home.

“Yessss! More….give me more Flux! F-fuck yes! Unf!” Rainbow pleasurably cried, plunging her hips down against the dildo she had fastened to the bedroom floor.

Her bedroom, or rather what formerly was her bedroom, had now become the location of endless debauchery. Getting rutted senseless every morning, evening, and night - as long as Flux was home, had become her new lifestyle. Taking a “temporary” leave from the Wonderbolts, as well as opting out of a hooffull of get-togethers with her friends, she spent nearly all of her time trying to sate the neverending itch that was her heat.

Wearing a white hoodie and now torn, yoga pants, she had originally intended to do an at home workout to catch up on the lack of exercise she had been getting, but that plan fell flat on its face nearly as soon as it started. She had managed to get herself off moments before it, but as soon as she attempted to start stretching, the roaring need spawned from several estrus spells came roaring right back in her abdomen. Instantly abandoning her original plan, she scurried to fetch her dildo, tore open the crotch of her pants, and screwed herself onto the silicone dong.

It was nothing compared to her Master, but it was the best option she had. She deeply yearned for him to be present here with her now, plowing her with reckless abandon while he shoved her face into the mattress, but unfortunately he was still out running some errands.

“Mmmmmmm ~ Fill me up Flux! Breed me like the slut I am! Oh my goooooosh!!!” she wailed, reaching her climax as she hilted the dildo within her constricting depths.

Shaking intensely, sweat dripping down her form and dampening the clothes she was wearing, Rainbow released a continuous flow of lewd moans. She had become addicted to the sensation of climaxing, nearly as much as she was addicted to Flux’s cock. Quivering in place, riding out the orgasm, she unceremoniously dismounted off the mock stallionhood and collapsed forward.

Panting in her afterglow, her marehood ceaselessly winking all the while, she grimaced as she felt the desire in her shoot right back to its full force. Truthfully, she wouldn’t feel a moment of release unless Flux’s stallionhood was within one of her holes, but she was well aware of that fact. Though the sensation of release was divine, the feeling of each and every orgasm she gave herself was almost as good.

“Seems somepony has been a good slut while I was gone ~” a familiar, masculine voice intoned behind her.

Rainbow’s eyes went wide, as her engorged clit pulsed excitedly. Wheeling around, she felt herself nearly swoon at the sight of the unicorn. Her pulse raced, her asshole throbbed, and she was immediately drooling from both ends.

“You’re home! I’ve been needing you Fl - ahn!”

Her excited remark was cut off, as the mark on her abdomen shimmered with color. Disobedience meant she’d be teased thoroughly, and such was the case with her referring to him by the wrong name. Her legs quivering intensely, fervent desire coursing through her very being, she meekly looked up at the stallion.

“Y-you’re home…I’ve been needing you…Master.” she corrected herself, grimacing slightly at the notion.

Flux raised a brow, unamused by the mediocre display of her obedience. Though it’d only take a bit of teasing or fucking to melt her into a mind-broken cumdump, she sometimes showed inklings of her previous ire. Especially when it came to addressing him properly.

Shaking intensely, feeling herself losing any semblance of sanity to her overwhelming carnal hunger, Rainbow grit her teeth as she looked over at him. “Please c-can you - mmmmmph!”

She was cut off for the second time in short order, as Flux magically taunted her clit. With his horn ignited in an arcane hue, he ruthlessly rubbed and teased the sensitive region of her dripping folds.

“What a cute little outfit you put on for me, slave. However, don’t think I didn’t notice that bit of hesitation in your voice just before~” he teased.

“Nggggh! I-I’m sorry! I didn’t mean it! Ah!” she cried out, losing herself to the ecstasy of his influence.

“Maybe you need a reminder,” Flux started, waltzing over towards the mare, rearing onto his haunches, and placing his stallionhood on her face. “Who am I?”

Rainbow felt her body freeze up, barely registering the question he had asked her, as the glorious presence of his stallionhood clouded her vision. Barely holding onto the meager fragments of logic her broken and corrupted mind still had left, she made a crucial mistake - she took a deep, strong breath through her nose. His aromatic musk flooded her sinuses like a torrent of aphrodisiacs, and the scent of the stud that claimed her dismantled what reason she had. Driven through pure primal lust, she drove her snout forward and attempted to lap at his nuts - though she found herself rejected of the right.

Frozen in place, her muzzle being held back by magic, Flux looked down at her with a wolfish smirk. “A-ta-ta ~ You have a question to answer, slave.” Grinding his stallionhood along her muzzle, flooding her sinuses with more of his stallionly aroma, he pressed her on. “I’ll ask again, who am I.”

Mindlessly trying to push against his arcane hold, desperate to savor the flavor of his package, Rainbow could only mumble an absentminded response. “M-Master…”

“Say it proudly, Slut. Tell me who owns you,” he continued, grinding his shaft on her further.

“Master…Master owns me….” she panted, biting her lip in anticipation.

Shrouding her marehood once more in his influence, plunging a magically formed construct into her depths, he questioned her again. “Announce it. Remind me of who I am. Who owns you.”

Her pleasure and need soaring to new heights, she inhaled deeply as she wailed, “Master! You’re my Master! You own me! Please! Please let me have it!”

Flux didn’t reply, simply releasing his grip on her. Within mere seconds, she lunged forward, diving her muzzle into the region where his shaft and nuts met. Letting her tongue fly out, she eagerly began lapping at his balls, suckling and worshiping his package with the expertise of a seasoned whore.

Looking down at her, savoring the sensations and sounds her action was creating, he reached down and stroked her prismatic mane. “That’s a good girl ~ fulfilling the role you were meant for.”

Suckling intensely on one of his nuts, she released the pendulous orb with an audible pop and looked at him with lust-crazed eyes. “Yeshhhh!”

“Get on the bed and beg for it, like you always do,” he commanded, stepping back and spawning a whimper from the mare.

“Y-yes Master!” she bleated in response, scrambling over towards her bed, giving a slight flap of her stiffened wings to clamber onto the mattress.

Obediently plopping onto the soft cushion, Rainbow reached back with her wings, pried her buns apart, and looked back at Flux with an expression that could only be described as pure lust. Time can do many things to a mare, and these last few weeks had undone every aspect of the pony she once was. Her confidence and ego were still in her, shining whenever she was with her friends or in public, but once she was alone or with Flux - her true self came out full force.

He had bested her, utterly defeating her and turning her into his personal cock warmer, and with that fact she was beginning to come to an acceptance. She was a slut, his slut, and she’d dutifully fulfil her new role in life. Being in a perpetual state of estrus, accompanied by the fact that she had to obey him, meant one thing to her. With the wondrous pleasure he could deliver onto her, being the only stallion in the world that could sate her, she would be his dedicated, subservient, and loyal slave…forever.

“Please Master~ I’ll be a good slave! The heat…I need your cock!” she furthered, shaking her ass seductively at the stud.

Flux felt his stallionhood throb below him, as his own lust continued to grow. Her display of obedience was as thrilling as ever, especially when he recalled how she used to look at him. That hatred and arrogance was now replaced with desire and need. Nothing more than his fertile plaything, one he fucked over and over again every day, she was now much more appealing to him than when she played the superhero charade.

Walking over towards the bed, he couldn’t help but feel a familiar concern in his mind rise through a sea of sexual thoughts. Pestering him once again, the notion that he could be doing more surfaced. He had only been in Ponyville for a few weeks, but there had been numerous enticing options.

The Wonderbolts were always on the table, and there were many members to choose from. There was also that zebra he saw on occasion. It seemed odd that she lived in the Everfree Forest, but that the juicy flank she had was unbeatable. The town’s mayor had caught his eye a few times too, and even though he wasn’t the biggest fan of older mare’s, she had quite the delectable figure.

“M-Master…please, I need you~” Rainbow weakly pleaded, her essence dripping from her snatch down her inner thigh.

Snapped out of his thoughts by her begging, Flux grit his teeth. The idea that he could do more was certain to run rampant in his head until it was resolved, but for now he wanted nothing more than to indulge himself in his conquest. Hopping onto the mattress, he draped himself over the mare.

“Yes! Please, please give it to me!” she excitedly cried, arching her back and pressing her rear back.

Shimmying forward, Flux brought the tip of his stallionhood to her entrance. Prodding her slickened folds, he leaned forward and whispered in her ear. “What are you?”

Biting her lip, fighting the urge to disobey her Master and throw her hips back to impale herself on his dong, she fumbled a response. “Y-your slave Master!”

Pressing only the tip of his tool into her depths, he pressed her. “What else?”

“A-ahn! Your slut! Your fucktoy! Anything you want! Please, just rut me!” she cried out in response, her marehood wantonly winking as it desperately begged to be filled.

Finding her admittance sufficient, as it usually proved, he gave her what she so badly wished for. Throwing his hips forward, he hilted himself within her depths in one, hard motion. Her walls immediately clenched onto him like a vice, as she threw her head back and screamed with rapturous delight. Her marehood gushed with her essence, as she climaxed on the spot. Words failed to escape her, as her expression warped into one of pure, euphoric bliss. Her body shuddered, her legs shook, and she ground her ass back against his crotch - eager to feel every last inch of him within her.

Holding himself in position, relishing the sensation of her depths clenching down on him with vigor, he felt his grin waver once more. Sooner than he had liked, the same thought from before came back to ruin his delightful time. Grimacing slightly, upset by the diversion from his fun, he pondered to himself.

Who would it be though?

Shaking his head, pushing the thought aside, he looked down as he watched Rainbow’s shuddering cease. Laying her head on the bed’s pillow, tongue lolling out, she panted and gasped for air. Her cunt continued to grip onto him, fully intending to not release him, furthering the fact that she had yet to feel true release.

“Moreeeeeee…I need more…” she slurred, slowly beginning to move her ass back and forth on his dick.

Opting to indulge his toy, Flux began thrusting into her with a quickening pace. Nearly unsheathing himself from her depths, he drove himself forward with force, kissing her womb with each plunge into her. She met his motions, throwing herself back in time with his drives forward, moans escaping her with each and every motion. On and on they went, breeding like a pair of animals in heat - though one of them quite literally was nothing more than an animal in heat now.

“Yes! Ahn! Mmph! Keep fucking me! Unf! Nggh! Use me!” she moaned, shuddering intensely as another intense climax wrought itself upon her.

Flux bit his lip, feeling the inklings of his own euphoric conclusion brewing within him. Pounding her with all his might, enjoying every second of utilizing his slave’s holes, his brow furrowed.

I could make more mares melt like this before me.

Damn his egotistical mind for pulling back the thought that irritated him so much. It wasn’t that Rainbow wasn’t good enough, hell, he would be perfectly happy having her and only her for the rest of his days. No, the issue within him was his own lust for power. Yes he was more than happy with her, but the fact that he knew he could claim more mares if he wished irked him more than he realized. Doing his utmost to dissuade the obnoxious thoughts in his mind, he found himself peering over towards the nightstand.

Feeling him flaring within her depths, Rainbow desperately begged for a proper reward. “Mmmmmph! C-cum inside me! Please Master”

Flux barely registered her words, as his focus was entirely on her bedside table. Laying atop it was a picture frame, but what caught his eye the most was the image within it. It was a picture of her. Her, and herfriends. The unicorn blinked wildly, as his mind rushed with ideas, and, as if the pieces of a puzzle all came together at once, he came to a revelation.

They were the perfect targets.

With a relieving sensation, that irritating thought in the back of his mind withered away within seconds. He had his answer. He finally knew what mares to pursue. Claiming one Element of Harmony was a rush beyond belief, but claiming all six of them would be another realm of excitement. His newfound ego needed to be sated, and the idea of claiming six of the most powerful and important ponies in all of Equestria, one of them being a princess, well, it nearly made him cum right there on the spot. Feeling like a horny genius, he slowed his thrusts to a halt, edging himself on the brink of a climax.

Feeling his motions end, taking a moment to register what was happening through her lust-addled mind, Rainbow slowly raised her head and looked back at him. “M-Master? W-why’d you stop?”

Her confusion soon morphed into fear, as she saw the devious expression plastered across his face. She knew that look, even back when her sanity wasn’t sundered into that of a total whore’s, and with it meant he was planning something despicable.

“Rainbow, my good little slut, you’re loyal to me ~ correct?” he cooly asked, condescendingly smiling down at her.

Her marehood giving an especially strong clench, due to being called a “good little slut”, Rainbow meekly replied, “Y-yes, of course I am…”

“More loyal than you are to them, right?” he continued, pointing a forehoof towards the picture frame.

Shifting her vision, focusing on where he was pointing to, Rainbow’s eyes went wide. Seeing what he was making note of, knowing full well he was referring to her friends, she felt her heart thump in her chest. Sure, she had fallen far from grace after he sundered her pride and ego with his erotic might, but to defy her friends was something beyond that. She was loyalty incarnate, or at least she was supposed to be, and the prospect of defying her friends in such a way challenged the deep, hidden remnants of the prideful mare she once was.

“I…I…I don’t - Ngggh!”

Not allowing her to properly reply, Flux began plowing her with all of his might. Throwing caution to the wind, he pressed her face into the pillow and slapped his hips against her ass. The sounds of plapping rang through the entire room, and her lewd moans bounced off the walls and back to her own ears.

“Need I remind you what you are? Who do you belong to? Did we not just go over this?” he asked, leaning down, biting her mane, and pulling her head back.

“Mmmmph! Y-you! Ah! Ah! I said I belong to you!”

“And you’ll do anything for me, isn’t that right? You can’t live without my cock, and you know it.” he continued.

“Y-yeshhhh,” she groaned, eyes rolling back as she was being sent to the gates of pleasurable nirvana.

“So let me ask you again. Who are you more loyal to?”

Feeling her feeble display of defiance collapse in on itself from his carnal might, she surrendered to him. It was the truth, the pleasure he delivered her bound her to him in both body and soul. She belonged to him, she needed him, and nothing would stop her from getting the pleasure and relief she so desperately craved - even if it meant going against all she was. Even if it meant defying her friends.

“Youuuuuuu! A-all my loyalty! All of it! It belongs to you!” she pleasurably wailed, intensely throwing her hips back to meet his thrusts.

Grinding his teeth, feeling his balls seizing, he gave one final titanic thrust and hilted himself within her depths. “Tch -take your reward, slut.”

Rainbow threw her head back in a noiseless scream, as she endured a catastrophically pleasurable climax. His massive shaft flared within her walls, and within moments she felt the first ropes of his foalbatter coat her walls. The sensation of his molten seed filling her womb to the brink brought her to a level of bliss unknown to any other pony in existence. He was good, just too good. She could never defy him, not with how euphoric his carnal deliverances upon her were. This feeling, the feeling of him claiming her to the utmost level, was something she was simply addicted to now. She never wanted it to end, and she could never escape it regardless. She was his, and he once again reminded her of that fact.

Her entire body seized, her nerves went alight, and fluids gushed from her cunt like a waterfall of degeneracy, as she waded out the final waves of her climax. Her womb overflowed with his seed, gushing his cum out of her depths in spurts. Her walls eagerly clenched down on him, desperate to milk every last drop from him, but alas their efforts were in vain. Unable to handle the overwhelming pleasure he blessed her with, she collapsed forward and released his stallionhood from her depths. Strings of cum coated her ass, tail, back, wings, and mane, baptizing her in her Master’s essence.

Breathing heavily, the two of them lay still for a moment, the only motions being the rise and fall of their chests. Eventually, Flux smiled once more, looking over her now cum-stained form. She was a wonderful slave, and also a wonderful tool. Laying beside her, looking at her face, he slowly stroked her mane. It took her a second to register what he was doing, but her rolled back eyes soon shifted focus on him. Breathing heavily, she moved her head forward and brought the stallion into a kiss.

He matched her efforts in stride, pressing his own lips against hers. Their tongues soon intertwining, they amorously dueled with one another until she eventually surrendered to him. The scent of sex wafted through the room, filling their sinuses with the aroma of their own primal lust, and it only drove them further into their embrace. Releasing a deep, throaty moan within his mouth, Rainbow’s eyes fluttered.

She was his, and she’d do anything to please him.

Slowly, Flux broke their kiss, pulling back as a string of saliva connected their mouths. He looked into her eyes, soaking in the sight. They weren’t the spiraled colors of her obedience any more sure, but they held within them the same level of obedience as they did way back then. This was her, the real Rainbow Dash, and he had conquered her beyond belief. He made her defy her element, her friends, and herself - all for the promise of being bred like the needy slut she had been shaped into.

Stroking her mane once more, seeing her shiver from his mere touch, he spoke to her, “And you’ll help me break your friends just like I broke you ~ isn’t that right?”

Hesitating for just a moment, Rainbow looked down at the mark on her abdomen. It was the mark of her obedience, the mark that signified that she was his slave. The mark that meant the Rainbow Dash of before was long gone, and all that was left was a loyal slave to Flux. She knew if she said no he’d force her to comply regardless, but she didn’t want to resist. She was loyal to him and him only, now and forever more, and with that she would fulfill any request he’d make of her - no matter who or what it entailed she‘d betray. Plus, she knew her friends would relish the wondrous joys he could give them, in the long run at least. They’d just need some…convincing, just like she foolishly did in the past.

“Yes, Master.” she cooed, licking his neck affectionately.

Flux could only smile. He had much planning to do, but with a loyal cocksleeve assisting him in his upcoming endeavors, he knew he’d succeed. The remaining Elements of Harmony would be his soon enough, it was only a matter of time. Looking back down at the mare, he caressed her cheek.

“Good girl.”
