“F-Flux! Let’s settle this!” the familiar raspy voice clamored from afar.

Fumbling out of his seat, Flux scampered to his door. Having built up his lust, fiending for an outlet of release, he found the prospect of rutting the mare endlessly more enticing than his own hooves. The set of videos he had just watched were incredible, and he’d enjoy nothing more than to indulge in the object of his passion from them. Scurrying out his office door, making his way down to the area where he heard Rainbow’s voice spawn from, he found himself face to face with the mare.

Hiding his stallionhood, keen on teasing her as he had so many times before, he straightened himself up as he met the mare’s gaze. She had a light blush on her face, and rubbed her thighs together - both of which had become a usual with their recent encounters. Her heat had now heavily clouded her mind, and it was painfully apparent that it had worn down her resistance over time. He no longer had to strategize how to duel the mare, nor did he even have a semblance of fear when facing her; all he did now was ponder over how exactly he’d make use of her body for the evening, as that's all she was now good for.

Clearing his throat, Flux began his usual song and dance of teasing.

“Settle what? Looking at you, it seems you might be wanting to settle something oddly…specific,” he started, soon pointing a forehoof at the mare, “And the way you’re sweating, I’m sure the flight from your home to here couldn’t have been that strenuous; looks to me like you’re dripping in more places than one ~”

Rainbow grimaced, as she felt her marehood wink. The fact her heat was affecting her so much was humiliating in its own right, but the fact that he was able to so easily tell what she was going through was another issue in its own right. Steeling herself, doing her utmost to push away any desires within her, she took a deep breath.

You go home next week. Just focus on that. Take him out…and just go home.

“S-shut up Flux! There’s nothing going on! Let’s get this over with quickly so I can head home and pack up.”

Hearing her retort, Flux’s ears twitched. Pack up? What was she on about? Tilting his head at the mare, attempting to keep his cocky demeanor, he questioned her.

“Pack up? What could you possibly mean by that?”

“W-what? Why do you even care?” she stammered, still doing her best to quell the raging fire in her loins.

“It’s a simple question, at least entertain me with an answer,” he sincerely replied, smirking lightly at her.

The sight of his face adorning the cute smile nearly sent Rainbow reeling. She cursed to herself silently. She had no real idea why he had become so enamoring, but he had and, due to it, dealing with him right now was much more difficult than it had to be. Still, some underlying part of her felt obligated to answer his question, as if he was a dominant force over her.

“Well…” she started casting her eyes away from the stallion. “I got a letter from Princess Celestia saying that I could go back home,” she turned back to the stud, glaring at him fiercely, “which also means this is the last time I’ll be having to deal with a loser like you.”

Flux felt his heart skip a beat, tapping his hoof nervously. If she were to leave, their nights of debauchery would seize. He had no way of keeping her here in Manehattan, and she seemingly was managing to fend off her heat, possibly with the prospect of going back home in the back of her head assisting her. At the current rate, this would be the end of their fun, unless…

“H-hey! What’s up with you? Scared of getting your flank kicked?!” Rainbow asked, confused by his awkward demeanor.

Seeing the stallion shuffling awkwardly, seemingly lost in thought, allowed her confidence to rise somewhat. Though her heat was raging on within her, the idea of her going back home helped her power through it, and, accompanied by the fact that Flux was anything but intimidating right now, she felt rather under control of herself.

Flux rummaged through his mind, working towards pulling in an inkling of information that dwelled deep within. He hadn’t used the mind altering spells of his book in sometime, having mastered the two primary spells a fair bit of time ago. Though, coming across this realization, he paused. He had only used two of the mind altering spells, having never used or tampered with the third.

Arcanely summoning his ensorceled book, he furiously flipped towards the entries containing the hypnotic spells.

“Uh…hello? What the hay are you doing?” Rainbow asked, her annoyance growing within her.

With each passing moment her heat was slowly overcoming her confident facade. If she remained in the presence of the unicorn for longer than she’d like, she feared she’d crack without him even so much as touching her. Still, she did want to best the stallion in a fair fight, certain it’d help her blow off some steam without having to actually get frisky in any manner, so she allowed him to continue whatever he was up to.

Flipping through the pages of his tome, he finally came to the section that contained the spells that started this whole journey.

Mens Dominationis and Diuturna Impressione, yup, he knew those two spells well. They were the keys to his endlessly sexual enjoyment over the past few weeks. Though, reaching the bottom of Impressione he noticed a bit of subtext.

…If the caster wishes to turn an individual into a permanent mindless puppet, refer to Totalis Servitus on the following page.

Totalis Servitus, how could he have forgotten. The spell was meant and designed to permanently instill the effects of Mens Dominationis. He had never opted to use it, as he found the buildup to his times with Rainbow, with the triggers as usual, to be much more enamoring. Fondly reflecting back at the tapes he had watched not too long ago, he quickly shook his head and focused on the task at hoof. Quickly flipping to the next page, he read Totalis Servitus’ entry.

When casted on a target affected by Mens Dominationis…permanently enthrall them…constant mindless puppet…cannot be undone…

Flux mumbled key words from the entry under his breath, scanning through it quickly. The spell’s details were simple - all he had to do was cast it on her while she was under Mens Dominationis and she’d be his mindless toy forever. Though, while looking over the text, he frowned.

Though the concept of having her as his needy enthralled slave at all times sounded phenomenal, Totalis Servitus felt…cheap. It was a one way ticket to guaranteed permanent success, but it felt too easy, hell, it honestly seemed downright unfun. There was no buildup, there was no game, there was no satisfaction of breaking her - it was just the usual song and dance but with one extra spell thrown in. Thing is, that one extra spell would solidify her erasure into nothing more than a doll.

Call him crazy, but Flux didn’t want that, he found a certain appeal to seeing her try and resist him. Furthermore, he found a love for a certain dynamic in the last tape he had watched. Having her willingly give in to him was the most erotic time of his life, and that night he had very nearly shattered her forever. Her heat had gotten so bad that she genuinely admitted she needed him, begging to be fucked not once but three times. Pondering over this, hearing the pegasus groaning in frustration, Flux tapped a hoof to his chin.

“Dude c-cmon! Seriously! This is so lame! I’m losing my - ugh - patience here!” she groaned, rubbing her thighs together at a quickened pace.

Her desire, specifically for him, was resurging in her. Try as she might to drown out the thoughts, images of him rutting her began to flood her mind.

Why…why can’t I just get him out of my head!

Ignoring her pleas, knowing her heat would slow her down enough that he could dodge her if she quit waiting, Flux came to a revelation. She had almost entirely broken before him about a week ago, which means there was an entire extra week of endlessly building heat within her now. She should be more frustrated, more desperate, and more willing than she had been days ago, which meant one thing.

Rather than enslaving her with the spell, he could possibly make her genuinely devoted to him as herself, not a slave, but as the real deal Rainbow Dash.

The notion sounded endlessly better to him than the domination spell. Having her as his willing slave, signifying that he broke her entirely due to her natural cravings as a mare, was somehow even more exciting to him than the idea of her being his mindless puppet. Tapping his hoof in thought, he formulated a devilish plan.

If he wanted to break her entirely, and have her devote herself to him, he’d have to step things up massively. If he failed, he’d just use the permanent enslavement spell, but that’d be a last resort. He’d make what happened last week look like a joke compared to what was in store for today. Teasing her far more, degrading her endlessly, and pleasing her beyond her comprehension would all be in play, but one important idea came to Flux above all else. Furiously flipping to a dog-eared page, he found the entry for a different kind of spell - the estrus enchantment he had used on her all those weeks ago.

He had used it on a whim back then, moments before she left him on the rooftop, and being so he neglected to read the remainder of its entry. He just used the spell as written, and it of course worked like a charm. However, there might be a bit more detail that could turn out to be vital. Having skimmed through it a while back, he could have sworn there was a detail regarding multiple uses. Focusing his attention on the page before him, he read the entry in detail.

Infinitus Calor is a heat inducing spell; the effects are similar to that of a standard estrus cycle, though this spell can also affect stallions. When used on a target, they will enter an intense estrus state, while also being unable to relieve themselves of it. No method of self satisfaction; be it toys, masturbation, or rutting can alleviate their heat. The spell will cause a nonstop building need in the mare, while also making them subconsciously crave the spellcaster’s body as their outlet of pleasure.

“Well that explains a lot,” Flux quietly mumbled to himself, before resuming his reading.

This enchantment can be casted multiple times, therefore allowing for an exponentially more intense result in a target.

There it is, the key to his victory. If one usage of the heat spell was enough to make her beg him for a lay after some buildup, he was certain another dose or two could bring her down entirely. If things went to plan, her overwhelming lust would lead her to the ultimate desperation, and ideally, she’d willingly abandon all else just to experience the pleasure in serving him. However, he also flipped to the following page, and took note of a seemingly brand new, and awfully intriguing, spell.

Devotionis Vestigium is a will-binding enchantment. It may only be used on a willing participant, and they must be informed of what this spell does. Upon use on a consenting subject, a marking of devotion will appear on the region around their crotch. The spell binds the target to the caster, they keep their personality and memories, and they cannot disobey the caster. Once the mark is instated on the target, an irremovable bondage between slave and master is formed. The marking increases lust, especially towards the caster, and will surge with pleasurable magic when the slave obeys a command. The target of the spell can only be satisfied by their Master, or the spell itself, if anything were to happen to the spellcaster, the mare is locked to an endlessly growing lust without release. Additonally, if a slave is impregnated, the marking will glow a bright purple, signifying the mare has been claimed to the fullest extent. This spell can be combined with Infinitus Calor, to cancel out the endless heat aspect of the aforementioned spell, allowing the subject to find temporary periods of relief from its effects.

Remember, this is a permanent enchantment.

“How the hell did I miss this…” Flux quietly berated himself.

Bingo. If for any reason Rainbow Dash did think about recovering from the mind shattering effects of their inevitable romp tonight, she would have already given in to him and accepted this new spell - she’d be unable to go back. It was a convenient, and ultimately perfect, safety precaution, and one that would ensure she’d be his forever while keeping parts of herself. He wasn’t sure just how he missed this spell, but he had long since accepted the book seemingly had a mind of its own; having added and removed entries from itself at random points. Though he often found that aspect of his trusty tome rather worrisome, he couldn’t love it more right now. He nodded to himself, fully confident that he had a full proof plan. Finally looking up from his book, he took notice of Rainbow Dash hovering slightly in the air. A noticeable string of her nectar dripping down from her rear and into a small pool below her on the floor.

“A-alright! That’s it! If you wanna st-stand there like an idiot then it'll just make this easier!” Rainbow roared, rising up into the air.

Flux was still painfully aroused, but he had to contain himself. Setting his arcane tome aside, he shifted his legs and took a prepared stance.

“Sorry, didn’t mean to leave you waiting for a good rutting. That is what you’re so impatient about, right?” he teased.

“W-why you! Ugh! That’s it! You’re done!” she stuttered, surging down towards the stallion.

Flux rolled his eyes, humored by the fact that she literally always took the same approach at him. Rise up, fly at him, fail. She was all about speed, and once he countered that part of her, she really wasn’t much of an issue at all. Easily dodging her attack with a quick teleport, he whirled around from his new location and hurled the trigger spell at her. Impacting her as she recovered from her attack, he temporarily disabled the underlying effect within her.

If he were to properly break her this evening, he’d have to make it special. No underlying mind altering spells. Just her body, her heat, and her needs. He’d handle things differently tonight, and he was adamant to ensure it was impactful.

“W-what the hay did you just hit me with?” she asked, “My head felt kinda funny for a second…” she continued, gently rubbing her temple with a forehoof.

“Oh nothing -” Flux replied, “besides, looking at that winking cunt of yours, I’d say a little headache is the least of your worries.”

Perking up immediately, having not noticed her tail had flagged itself, Rainbow clamped her disobedient appendage downwards as she wheeled around to face him. “Agh! Sh-shut up! Seriously! I’m getting tired of you!” she retorted, as the crimson hue across her face darkened.

Smirking to himself, licking his lips in anticipation, Flux began channeling magic into his horn. Though, this wasn’t the normal locking or enthrallment spell, no, it was that wonderful little estrus spell the ensorceled book had contained. Feeling the spell surge in his horn, he took a readied stance as he awaited Rainbow’s next attack. As if on cue, she immediately surged towards him in another feeble attempt to strike him down, and, as was the usual, he simply warped away. Emerging only a few feet away from where she impacted the ground, he quickly aimed his horn at the mare.

“Will you just stand still and - NGGH!”

Rainbow’s words were cut off, as the second Flux’s spell impacted her, her entire body went alight. The original heat spell’s effects had already broken her down immensely, but upon a second entering the field, her body surged with unimaginable need. As it coursed through her, intermingling with the first effect, the estrus spell infected her body with a newfound lust. Within moments, her nipples had gone fully erect, her tail fought to flag itself, and her marehood winked with endless desire. Visibly shaking from the coursing pleasure throughout her, she grit her teeth.

“W-what…what did you - ahnn - what did you just do to me!?” she stuttered, heavily distracted by the waves of lust coursing through her.

Flux looked at her with a condescending smile, knowing full well she was facing an intense inner battle. One extra dose and she was already wavering, one or two more should push her over the edge.

“Just a little…encouragement, so to speak. You came here as a bitch in heat, so why not remind you of it a bit more?” he taunted, licking his lips as a gush of her nectar dripped to the floor below.

“I…I…”

She found her words locked in her throat, as a torrent of images flooded her mind. Each and every single one contained Flux, and accompanying him was the sight of her getting plowed. Missionary, doggystyle, cowgirl, any and every position her lewd mind could think of had an accompanying image of them doing it. Being her body was already desiring him intensely, she was giving it her all to hold onto reason with this newfound hunger.

“Mmmph! I…I did not come here like that!” she scowled, surging towards him once more.

She was much slower this time, due to the intensified heat hindering her abilities, and Flux had immense ease with dodging her strike. Warping away, with another surge of the heat spell channeling in his horn, he watched as she landed with a thud, releasing a frustrated growl as her tail fidgeted furiously. Not wasting any time, he once again aimed his magic at her.

“S-stop dodging and just - Ahn!”

Once more her retort was cut short, as with a third dose of the spell, she nearly fell to the floor. Her legs buckled, her tail flagged itself fully, and her marehood gushed with her essence. As the additional enchantment coursed through her, she found herself lost in a sea of endless desire. The images in her mind of Flux only grew more potent; the vivid sights of the thrills he could deliver to her coursing through her better judgment like a torrent of euphoric bliss. With the image of him bending her over, plapping her senseless rising in her mind, she bowed forward, panting furiously as her cunt wantonly winked, and left her ass remaining up as she subconsciously bucked her hips back into the empty air.

“S…so good…nnnf…I…n-no…” she mewled, weakly attempting to stabilize herself.

Her entire body was shaking with unforeseen amounts of desperation, and her marehood was dying to be filled. She wanted nothing more in the entire world than for Flux to claim her right then and there, but within her some remnants of her defiance remained. She’d be on her way back home in a few days, she could finally get away from this damn nuisance that’s plagued her mind with his body and his cock. Doing her utmost to steel herself, barely holding onto reason, she slowly turned around.

“I…I’m not…gonna…” she continued, weakly lunging out at Flux and collapsing forward.

The attempt was laughable, nothing like the usual fierce energy her strikes at him contained before. There was no power, there was no speed - it was just a pitiful, weak, pointless lunge trying to step up against a dominant, virile stud. Her heat was demolishing her, leaving her as a quivering mess before him, and her vitriol was collapsing at an exponential rate. Try as she might, she couldn’t even fly at him anymore. Her wings had stiffened due to her endless arousal, and she could barely focus on the task at hoof. The last remnants of her clear mind seemingly were wasted on a feeble attempt of a punch at him, one he more than easily sidestepped. Upon missing her swing, her legs gave in and she toppled to the floor.

Flux looked down at the mare to his side, witnessing her quivering form as a pool of her essence began to form by her crotch. She was biting down on her lip as she clearly fought an internal battle, but upon seeing her slowly begin to reach her hoof down to her snatch, he knew his plan was moments from succeeding. Aiming his horn at her again, he decided to deliver one last vital dose of the estrus spell.

“T-too much…I need - oh my goshhhhhhhhhh!”

As the last surge of the heat spell hit her, her facade shattered. Like an eager whore, her hoof darted straight to her snatch, and she began furiously rubbing her sensitive bud. Convulsing on the floor, she wantonly got herself off mere feet from a sworn enemy of hers. The last few hits of the spell had done a number on her, but this fourth one wrought a cataclysmic blow to her defiance.

She continued to rub herself intensely, forgetting all about the stallion beside her. The burning in her abdomen was unbearable, and all she could think about was the prospect of relief. Her pride would melt at the idea of her doing such an act in front of anypony, especially one she looked down on like Flux, but the heat was simply too strong. Over the last few weeks a dormant, unknown part of her was slowly surfacing - the part of her that was nothing more than a whorish mare. She would have hated doing this a little over a month ago, but as she rapidly rubbed her own clit in front of Flux, she felt a sting of excitement shoot up her spine. She had been craving him for weeks on end, and now that he was standing over her, observing her sorry state like the slut her estrus had molded her into, it filled her with a sense of fulfillment.

“Unf! Ahn! Nghh! S-sweet Celestiaaaaaa!” she wailed, as nonstop surges of pleasure coursed through her every nerve.

Flux watched as the cyan pegasus writhed in the endless rapture of her self-indulgence. Her juices were gushing from her marehood, as she played with her twat with vigor. Bucking her hips into the empty air, throwing her head back, she continued to pleasure herself without a care in the world. Her pride was already tarnished, but with four times the intensity on her estrus, in such short notice too, it completely obliterated it.

“Yes! Yes! Oh buck yes! Oh my gosh! Oh my goooooosh!” she continued to pleasurably cry, as her tongue hung loosely from her maw.

Flux knew he could take action now, likely easily managing to fuck her if he wanted, but he opted to wait. He’d tear down the remnants of herself, and mold her into a perfect, little, willing fuck-toy for him.

“Ahn! C-cumming! Mmmph! It’s s-so good! Ah! Yessss! NGGGGHHH!”

The Wonderbolt arched her back once more as she thrust her hips upwards, holding herself in the position as she reached a climax. Throwing her head back, eyes rolling into her skull, she let out a silent cry as her cunt spewed with her ecstacy. Quaking all over, she rode out the cataclysmic orgasm, her consciousness fading in and out the whole while. After a few, euphoric moments, she finally relaxed her body, unceremoniously dropping her position and laying down on her back fully once more. She lay there panting, as she reached her slickened hoof up to her mouth and lapped her own juices off of it. A bead of nectar was connected between her foreleg and crotch, showcasing how positively drenched she was down there. Though she held a joyful grin for a moment, it quickly warped to one of dismay.

“S-still…so…so hot…why…why won’t it just-”

“Go away?” Flux interjected, looking over at the lustful mare with a wolfish smirk.

Rainbow snapped her head over to him, her crimson blush deepening as she realized she had put on a shameful show for him. Though, her initial concerns lasted but a moment, as before she could respond her gaze drifted from that of his face to his lengthy equipment. Laying her eyes on his titanic stallionhood, her marehood gave an enthusiastic wink, and the heat in her abdomen soared to new heights. Any defiant retorts, prideful comebacks, or lies to defend her ego evaporated instantly, as the sight of a proper stud’s cock before her clouded all of her logic and reason.

“S-so…so big…” she muttered in response, unable to continue her initial thought as she stared at his groin.

Throughout her estrus, her desire in general had soared, but her unknown desire for him was a whole different level. His stallionhood hung below him, pulsing every few moments, enthralling her with the sight of it more and more. She couldn’t deny it, no matter how much she may despise that stallion, and how much her wavering pride screamed from within, she knew that his cock could stretch her depths with astoundingly pleasurable results.

“Oh? What happened to that cocky attitude you came here with? Did you finally realize how much of a slut you are? Giving into your needs as a mare?” Flux taunted, hitching his hindleg and showcasing his endowment to the mare.

Her mouth began to drool, as the all too familiar images of him plowing her filled her mind.

“N-no…” she murmured in response, feebly trying and failing to pry her eyes off his massive tool.

Chuckling lightly to himself, he trotted over to the pegasus. He had nothing to fear at this point, she was quite literally powerless against him. Stepping beside her, noting that her eyes tracked his groin the entire time, Flux craned his head down and whispered into her ear.

“You can just admit it Rainbow ~ I can see how desperate you are,” he began, magically shrouding the mare’s tits with his magic, “I don’t think I’ve ever seen a mare this desperate. I mean, look how hard these cute little things are!,” shifting his magic, he shrouded her marehood in his arcane ability and teased her clit, “and I’ve never seen a mare dripping this much. You really are just a whore, aren’t you?”

His teasing had brought her to admittance in the past, but with four additional heat spells coursing through her, Flux figured it’d be immensely easier this time around - and she proved his assumption within moments.

“Ngggh! Ah! I-I’m not…agh! J-just give me it, p-please!” she exclaimed, before her hooves snapped up and covered her mouth.

“Give you what?” the unicorn responded, pausing his teasing on her cunt and giving her a condescending smirk.

Rainbow grit her teeth, as she briefly threw her gaze away from Flux. She wasn’t exactly sure what he had hit her with, but all she knew was the deep, dark desires she had for him were exploding to the surface. Every thought in her mind was centered around his dick, and she couldn’t deny it. Hesitantly craning her head back towards him, her eyes immediately focused on his endowment. The sight of his twitching, massive length sundered the last vestiges of her resistance. With the heat in her abdomen roaring to unimaginable heights, she gave voice to her hidden desires.

“Y-your…your cock ~ okay!? Please! I…I need it! I need you!” she screamed in admittance, looking up at him with desperate, lust-filled eyes.

“Oh Rainbow, it feels good to admit it, doesn’t it?”

Rainbow’s desperate expression shifted back to that of a scowl, but before she could retort she froze. Flux had shifted his head, now meeting her muzzle with his own. Blushing deeply, her logic barely able to scrape to the surface through a sea of endless lust, she scrunched her muzzle.

“W-what are you - mmmmm!”

Having paused for only a moment, Flux pressed forward and kissed the prismatic heroine. Blinking wildly, she melted from his embrace, pressing back into the kiss as she reached down to her snatch with a hoof. Rubbing herself once again, the heat in her body simply impossible to bear, she worked on getting herself off whilst in the throes of a passionate makeout. With ease, Flux overpowered her tongue, allowing him to enter her mouth. Feeling and hearing her moan into his mouth, as she continued to play with herself, he felt up the insides of her mouth with his tongue. Saliva sloppily dripped from their mouths, as the messy embrace escalated with Rainbow using her wing to pull the stud in. Holding him close, she brought her free hoof up and held his head to her, ensuring he continued making out with her. Moaning openly into his maw, throwing away any remnants of her previous ire and pride, she indulged herself in the desires her body and mind had pleaded for for weeks.

Shrouding her tits in his magic, Flux elevated the kiss to newfound levels, causing the mare to release a loud, passionate cry into his mouth. Containing a chuckle, adoring the state she was in, Flux pulled back from the kiss. Biting her bottom lip affectionately as he departed, he rose back up to his towering form above her, as she panted below him.

“Trust me, I know you want me to give you this.” he noted, flexing and slapping his stallionhood against his stomach. “You came here just thinking about being plowed, didn't you? Well, unfortunately, for all the trouble you’ve caused me, you’re gonna have to earn it.”

“Uh-huh…” she dumbly admitted, fully enamored by the sight of his cock once again.

“Let me repeat myself,” he continued, forcing her head up with his magic. “If you want anything of the sort, you’re gonna have to earn it,”

Finally snapped out of her stupor, recognizing and realizing his words, Rainbow attempted to respond. “W-what? H-how?”

“Let’s start small. You did this once before, minutes ago, but I’d love to see it from an even better angle.”

Recoiling slightly, her eyes widened as she realized what he was getting at, “Y-you don’t mean…”

“Sit up, spread your legs, and masturbate for me. I wanna see you be a good slut and put on a proper show this time.”

Rainbow shifted awkwardly before him, her mind dueling with her body. Though, her mind itself had long ago yielded to her desire, and thus she made her decision with ease. Slowly, she stood up, sitting on her rear, and fixating her attention on Flux’s cock once again.

“Do I need to repeat myself? Or do you want to go back home without a properly fucked cunt?” Flux continued, giving her a menacing glare.

Nervously, Rainbow pried her eyes from his stallionhood and met his glare. She bit her lip in excitement as his dominating eyes drilled into her. Feeling her pussy give another wink, the fur of her thighs now drenched in her fluids, she gave in to his demands. She wanted, no, needed him, and she’d do anything to finally get what she so desperately desired. As long as this heat persisted, she’d do anything to get a good rutting from him - and only him. Stretching out her aching wings, she leaned back slightly and spread her legs. Making to reach down to her snatch, she gasped in surprise as her hoof was stopped short by Flux’s magic. Looking back up at him, she was met with a devious expression on his countenance.

“Actually, before you do anything, I want you to present yourself,” he demanded.

Gulping heavily, sweat dripping down her tired and worn form, Rainbow nodded as she slowly reached down to her groin with a hoof. Pulling at the flesh around her inner thigh, she took a deep, shaky breath. Focusing at all right now was incredibly difficult, as it took every fiber within her body to not throw herself at Flux and take in his cock. Gradually, she spread herself for him, revealing the soaked inner walls of her cunt. Her blush deepening as her arousal soared, she looked into the dominating stallion’s eyes.

“Tell me you’re a needy slut,” he commanded.

“H-huh?!” she questioned, eyes going wide at his request.

“I said, tell me what you are. Tell me you’re a needy slut,” he pressed.

Fidgeting awkwardly, sweat running down her forehead, Rainbow stammered, “I…I…”

“If you don’t, you can just go home. You won’t be getting an inch of my cock in you unless you tell the truth.”

Clenching her eyes shut, understanding that she absolutely had to do this, she took a deep breath and steadied herself.

“I’m a needy slut…” she weakly replied, a spike of hesitation causing her words to drown out.

Shrouding her tits once more in his magic, mercilessly twisting and pulling her hardened nipples, Flux reiterated himself, “Louder. I want you to acknowledge the dirty whore you are deep down. You aren’t a hero, you’re just a slutty mare.”

The sensation of his magic on her tits was unlike any other stimulation her small bosoms had ever received. Each time he had done it to her in her memory, the abstract mixture of warm magic and rough teasing sent her mind reeling, but with all the newly established magic flowing within her, it wrought an even more impactful effect this time. Throwing away her hesitation, she opened her eyes and threw face up to the sky.

“I’m - ahn - I’m a needy slut!” she cried, trying and failing to suppress the torrent of moans trying to escape her lungs.

“My slut,” he corrected, giving another firm yet pleasurable twist of her nipples.

“Y-yes! Nggh! Your slut! I’m your slut! Now please, just buck me!” she blared, her words dripping with desperation.

Satisfied with her admittance, Flux walked over to the whining mare, standing over her once more.

“See? It feels good to finally just accept it right?” he teased, raising his foreleg to give her a better look at his package. “Now, back to the original plan - get yourself off in front of me.”

Rainbow could barely register his words, as she stared longingly at his cock. Sweat dripped down her form, coating her in a musky layer of her own strenuous effort. The room was filled with a fruity aroma, spawned from the copious amounts of juices dribbling from her marehood. Her eyelids fluttered as another surge of lewd imagery funneled into her mind.

“Ahem -” Flux coughed

Blinking wildly, Rainbow snapped from her stupor, “Mmmmm - huh?!”

“Sheeesh - you’re really that desperate?” Flux teased, rolling his eyes at the mare. “I said, masturbate for me…that is if you really do want what I have to offer.”

Rainbow stared longingly at his package once again, consistently finding her eyes drifting back to it over and over.

“Y-yes! I…I need it,” she whimpered.

“Well, then get to it,” he snapped back, looking down at the quivering Wonderbolt.

Nodding languishly, Rainbow shifted and laid herself on her back. Taking a single, deep, nerve-filled gulp she slowly spread her legs. Her nectar spread from her marehood to her inner thighs, creating several thin beads of her essence flowing from her slavering folds. The roaring need within her was flowing through her like a current, and her entire body was shimmering with its heat. Slowly, gliding her hoof downwards towards her snatch, she hovered over her winking cunt. Doing her utmost to contain any shreds of her self-control left, she slowly pressed her hoof against the sensitive region. Though she had intended to contain herself to a point, the second her pussy was stimulated, her entire body convulsed in pure pleasure. Throwing her head back, unable and unwilling to hold back, she began rubbing herself like that of a wanton whore.

The culmination of several estrus spell inflictions on her had sent what was already an overwhelming heat into an utterly impossible to deal with one. Her body and soul craved for pleasure, craved to be bred, and most especially craved Flux. The smallest stimulation sent her nerves into overdrive, and once more her mind filled with the sole depiction of Flux pummeling her marehood with his irresistible cock.

Damn her if she knew how she ended up like this, but at this point she didn’t care. She lost - something every fiber of her existence would have despised some weeks ago, but as she got herself off with passion, she felt a sense of fulfillment. As long as she did what she was told, Flux would grace her with his own body. The mere thought of what he could do, and hopefully would do, to her elevated her desperation to another level. Throwing her head up, bucking her hips up into the air, she continued to tease her clit to her best ability. Lavishing herself, she bit the tip of her wing in an attempt to suppress the endless sea of pleasurable cries attempting to escape her.

“Let me hear how badly you need it,” Flux demanded, taking note of her efforts to suppress herself.

Any concepts of restraint were long gone from Rainbow’s mind, and within moments of his command she pulled her wing away and voiced her inner needs.

“S-so bad! Ahn! I want it so bucking bad! Ngh! Ahn! Ahn!”

Somehow, she managed to intensify her already astounding efforts. Rubbing her sensitive bud with renewed, endless desire, she found no end to her vocalizations.

“Your cock! Ah! It looks so good! It’ll feel so good! Mmmph! Fuck me! Breed me! Claim me! Pleeeeease!”

As she finished her intense cry of admittance, she reached another astounding climax. Her nerves went alight, her eyes rolled back, and she felt herself leave the realm of consciousness for a moment. Nectar gushed from her folds as she thrust her hips up and held position. Biting her lip, giving her all to remain conscious, she rode out the orgasm with every fiber of her body. Seconds felt like hours, as the endless waves of mind-shattering pleasure coursed through her every cell. Shivering intensely, feeling her legs lose their strength, she fell back flat on her back. The climax had run its course, but with another throaty, pleasurable moan, she came to a horribly familiar realization.

The heat was still there.

Her arousal hadn’t subsided in the slightest, hell, it was even more intense now than it had been. The estrus spells coursing through her were only intensifying with each passing moment. Weakly shifting back up, sitting on her haunches, she clenched her eyes in frustration. Gritting her teeth, knowing she’d lose herself to her lust any moment now, she cried out to Flux once more.

“P-please can - nnnf - can you rut me now - wha?”

Her plea was cut short by an unknown warm sensation pressing against her face. Holding her breath for a moment, she slowly opened her eyes, which soon went wide as dishes. Within a few short moments, deaf to her surroundings due to her frustration and lust, Flux had managed to place his cock directly onto her muzzle. Registering his colossal endowment laying directly upon her, she shivered in place. Biting her lip, she slowly took a deep breath through her nostrils.

The aroma that met her sent her reeling. With Flux’s musk filling her sinuses, her thoughts were overcome by the primal, unending desires within. Twisting her head, she engulfed one of his nuts into her maw, lavishing it with her tongue. Suckling on the pendulous orb with all the eagerness of a whore, she released a muffled moan. After some time she switched to the other cum-filled sphere, continuing to service his coin purse. She massaged the ball in her mouth, pressing and running her tongue along its form while lovingly suckling on it. Taking in the taste of his natural flavor and sweat, she moaned once more.

Popping it out of her maw, she drew her tongue over both his nuts, continuing to savor the euphoric earthy flavor they provided. Lapping at them continually, she paused her efforts and pressed her muzzle into the region where his shaft and nuts met. Taking in another deep, lustful breath, she quaked as his mesmerizing scent coursed through her olfactory senses once again.

Releasing a pleasurable groan, she drew her tongue up along his shaft, coating his member in her saliva. Looking up at him, her eyes filled with bestial need, she made her way up to his tip. Reaching the top of his stallionhood, she lapped up the glob of precum it had produced, swallowing eagerly as she did so. Swirling her tongue around his tip, coating more of his cock in her saliva, she nearly jumped as she heard him clear his throat. Meeting his gaze with her own, she froze as he glowered down at her.

“I suppose you did good enough. Why don’t you get it ready - before I fuck you senseless.” he directed, thrusting forward and forcing another inch of his cock into her maw.

Giving a surprised gasp, muffled by the cock breaching her maw, Rainbow eagerly fulfilled the villain’s request. Throwing her head forward, she engulfed his cock down her throat. Managing to take in a majority of his dick, she paused just an inch or two short of fully deep-throating him. Drawing back, taking in a deep, filling breath, she plunged forward once again. Her insatiable lust empowered her beyond her own knowledge, and seemingly through sheer force, she managed to deep throat him entirely on the second plunge. Removing her own ability to breathe, she pressed her muzzle into his abdomen. Holding position for a moment, she allowed her tongue to narrowly slip from her filled mouth and lightly slide along the very bottom of his shaft. Her lungs soon beginning to burn, she withdrew back to his tip, lovingly swirling the region with her tongue.

Moaning in pleasure, once again savoring his divine flavor, she began to furiously bob her head onto his shaft. Engulfing and releasing his stallionhood in rhythm, she dutifully sucked him off to her best ability. She never had much practice taking a cock down her throat, but her endless estrus fueled her beyond wildest beliefs. She needed him - and now that she finally had the cock she had been deeply yearning for for weeks, she refused to not savor every imaginable second of it all. Worshiping his cock was driving her wild; the taste of his sweat and flesh, the heavy musk, and the sensual moans he gave above her all culminated into an extraordinarily arousing experience. Continuing to service him, having long ago lost any thoughts of restraint, she felt her aching marehood furiously winking.

She would have reached down to rub her own snatch, if he was going to make her commit to this action for much longer, but fortunately for her, Flux seemed to be reaching his personal peak. Forcefully shoving his member fully down her throat, she steeled herself as she felt it flare within her. With another moan, he released hot ropes of his essence into her. A month ago she’d be disgusted by the mere notion of him doing such an act to her, but now she only felt upset that she wasn’t able to taste his seed. Releasing a few more threads down her throat, Flux withdrew his cock and released her head. Given the chance to breathe, Rainbow threw her head back and took a desperate breath. Panting, she licked the rim of her mouth to savor every last possible bit of his taste.

Feebly sitting before him, shivering from head to hoof in unending need, she weakly looked up at him.

“Please - cough - please…rut me now…I can’t handle this anymore…”

Muttering to himself, Flux shrouded himself in a spell. Staring crestfallen at his softening cock, Rainbow perked up as it nearly immediately grew back to its full, enamoring state.

“Oh, you’re gonna get rutted alright - all night.” he dominantly proclaimed, standing confident. “Turn around, you’ve been a good slut, so I’ll finally reward you.”

He smiled softly as he watched the mare immediately straighten up, whirl around, spread her legs, and lift her tail. Though he used no mind altering spells on her, she seemingly was as obedient as if he had. Reusing the stamina spell was a key factor to his plan - he’d give her pleasures beyond her wildest dreams all night. If all went to plan, she’d be utterly addicted to the carnal deliveries he could provide, and having her willingly devote herself to him would be a simple effort. She would still be in a perpetual state of estrus, for as long as he’d like, but being the parameters of Devotionis Vestigium, she’d find some release if he graced it upon her.

Mounting her, placing his hindlegs on her sides, he felt her shaking below her. Her marehood was a literal fountain of her essence, as threads of her juices dripped to the floor below. Literally making a puddle of her desire, she looked back at him with eyes of utter, desperate lust.

Prodding her entrance with his tip, he rubbed her cutiemark with his hoof. “Tell me, what are you?”

“Y-your slut!” she quickly snapped back, shimming her legs as she struggled to contain herself.

Forcing only the tip of his cock into her pussy, stretching the moist folds slightly, he continued. “And?”

“Your whore! I’m your whore!” she cried, attempting to push back into him, finding herself restricted by his foreleg holding her back.

Chuckling at her feeble attempt to fuck herself on him, he furthered his questioning. “Aaaaaand?”

“Your bitch! Your mare! Your cumdump! Anything! I’ll be anything for you! Just p-please! Give me your cock!” she wailed, her voice dripping with the most pure desire Flux’s ears had ever registered.

Smugly glancing down at her, he decided to give the mare exactly what she needed. Smacking her flank right on her cutiemark, she gave a yelp of surprise that shifted to an immediate cry of pleasure. Plunging his cock into her slowly, stretching her walls with his gargantuan length, he listened to the wondrous song Rainbow’s blissful moans sung.

“Sweeeeeet Ceeeeleeeestiaaaaaaaaa!”

Having only slid himself into her moist confines, not even beginning to thrust, he felt her entire body freeze up as she immediately climaxed. Her marehood clenched down on him, her juices gushed from her folds, and he was positive her asshole was pulsing rapidly. Holding his position, he waited patiently as she convulsed and cried below him. Her cunt continued to grip and savor his cock, finally having the sensation of penetration it had craved so desperately for. With another throaty moan, Rainbow’s convulsing seized. Slowly, she looked back at Flux with sweat beading down her brow.

“Well, seems somepony had fun -”

“More,” she interrupted.

Flux blinked confusedly for a moment, before her countenance adorned an expression of devious intent, “Eager, aren’t we?”

“Please…I just can’t get enough. I need more, you’re…you’re so good…” she weakly continued.

Flux gripped her hips once more, forcefully pulling her back as he began to pummel her pussy with renewed vigor. Her pleading so pathetically to him, after just climaxing, was music to his ears.

“Yes! More! More! Thank you! Oh my goooooooosh!” Rainbow wailed, now meeting the tempo of his thrusts by forcing herself back to match them.

His length slipped into her confines with immense ease, as although her pussy was tight, the sheer volume of her wetness made the act of plapping her senseless as easy as could be. Leaning forward, he bit down on her mane and pulled her head back, much like he had done some time before.

“Nggggh! Yeeeeeeeesssssssss!” she moaned, the subtle pain from her hair being tugged meshing with the pleasure she was experiencing in an immeasurably arousing blend.

Flux continued to fuck her with fury. There was no gradual buildup to his thrusting, just him going straight to an all out rutting - much to her pleasure. Her depths were as tight as ever, and her lewd moans were fueling the flames of his passion. Throwing her ass back against him, her flanks jiggling subtly from the force of her motions, she fell into a euphoric miasma. The world around her spun, her body was on fire, and every single possible thought within her mind was focused on just getting more cock.

She genuinely didn’t care for anything else in the entire world. The Wonderbolts, her role as an Element, everything and anything was less important than the pleasures she was being delivered right now. Every fiber of her existence yearned for this, and her pussy dutifully clenched onto every single inch of Flux’s cock. Her walls held firm, engulfing his stallionhood in their divine presence - all while she herself fell further down the well of passion. He continued to hold her head back, clenching his eyes as he fucked her with reckless abandon. She could barely hold onto consciousness, as the ecstasy being given to her was beyond her wildest dreams. The flaming heat within her roared, but with each forward thrust of his cock, accompanied by her throwing her ass back, she felt it get shrouded by the stimulation he gave her.

“D-don’t - ahn - don’t stop! Rut me more!” she wailed.

Flux barely could register her pleas, as he himself was now sinking into the depths of his lust. Clenching his eyes, baring his teeth down on her mane, he continued to pummel her marehood with his best efforts. He knew he’d keep going for several hours, since his goal was to truly have her dedicate herself to him, but this first time felt like something special. For him, this was the beginning of her permanent reliance on him, little to her knowledge - not that she likely cared anymore anyways. This was her, no mind altering spells in play, pure, genuine Rainbow Dash. The mare that was once this headstrong, cocky hero, was now this gushing, needy mare desperate for his cock. It was a wondrous development, and a sense of fulfillment came to Flux. As she continued to clench around his cock in an effort to receive his essence, he knew he was what brought her to this point. She was conquered by him. Looking down on him, thinking she was superior, always defeating him at first - things were now how they should be. She was nothing more than a slut now, his slut, and he’d ensure he’d make that arrangement permanent. Though he was losing himself in his lust, he still was determined to carry out his carefully concocted plan.

Their romp went on for what felt like hours, and Rainbow had no idea how many orgasms she had experienced in short order. Over and over she felt the sensation of release, just for it to be immediately overwhelmed by the heat within her. Though, with it, her desire for Flux only grew. Hearing him grunt above her, she braced herself for his seed to flow within her.

Though it never came.

Her eyes widened as she felt him begin to withdraw his cock from her depths. Her walls held onto him like a vice, desperate to not feel the empty sensation of his absence. Though, ultimately her subconscious efforts were fruitless, as he managed to pull himself out of her entirely. Craning her head back, confused and saddened by the denial of his foal batter, she watched as he climaxed. Spewing his cum all over her back, covering her coat and wings with his divine fluid, she shivered as its warmth covered her. Though the denial of his seed was disappointing, the sensation of his essence on her furthered her endless arousal somehow. Leaning down, swaying her ass back and forth, her marehood gave an enthusiastic wink.

“More…gods please more.”

Flux didn’t immediately answer, simply choosing to walk back, and lay down on his back. Shifting himself, spreading his legs, he allowed his cock to stand tall. Licking his lips, eyeing the mare’s slavering folds, he gestured for her to walk to him. Understanding what he was requesting, Rainbow whirled around and eagerly trotted over to him. Without even being told, she worked to position herself over his cock, before being stopped short.

“A-ta-ta,” he tutted. “Clean my cock with your mouth again,” he continued, pointing down at his member, “Every time after I fuck you, I fully expect you to clean me off before I fuck you again, got it?”

“Whatever you want, just please don’t stop giving me it…” Rainbow answered, shimming herself back and leveling her mouth with his tool.

Dutifully, she engulfed his cock into her mouth once again, and for the second time that evening she sucked him off to her best ability. Forcing his stallionhood down her throat, she lapped up her own juices off of it. The taste of her own essence met her, as a flavor akin to fruity candy caressed her taste buds, accompanied by a spicy kick. Forcing herself up and down his tool, she greedily inhaled as much of his musk as she could. The mixture of her own scent, accompanied by his, filled her nostrils with a sensational combo, and not only that, the mixture of their aromas felt right. She wasn’t sure what was telling her that, but knowing he was the one conquering her was beginning to feel like destiny. Her mind was clouded by her arousal, and with that her thoughts were far from her old, clear ones, but she didn’t care. This felt right, he felt right, and a part of her never wanted it to end.

Thoroughly cleaning his cock, having suckled each drop of her fluids off of him, she released his tool with an audible pop. She looked up at him, struggling to restrain herself from hopping on his cock and wantonly fucking herself on it then and there.

“Is…uhm…is that good enough?”

She held his cock with her hoof, absentmindedly stroking it whilst she awaited his response. No matter what she tried, she just couldn’t keep away from it. The mere sensation of touching it was painfully exciting to her, and with each stroke along his tool, she felt her marehood give a wink in sync with it. A part of her tried to imagine some other stallion with her, just like she had weeks ago in her tub. Soarin, Quibble, Thunderlane, her imagination attempted to form an image of any of them, but each and every time it focused on Flux and Flux only. She didn’t mind, honestly, she preferred it. He was a real stallion, and she wasn’t sure how she had been so oblivious before. The wonders he could deliver her were astounding, and her biological impulses yearned for him.

“You cleaned it well,” he noted, raising a brow as he looked over at her.

Awkwardly shifting in place, continuing to stroke his cock as she hungrily gazed at it, she stuttered. “C-can I please…”

“Please what?” he harshly intoned.

Hearing his voice reverberate in her ears, she felt her marehood seize upon itself. His voice dripped with dominance, and though the rebellious portions of herself, or rather the former rebellious portions of herself, may have opposed being spoken to in such a way, she now desired it.

“Ride your cock! I need more of it! I need to feel you inside me!” she excitedly answered, standing up and positioning herself over his length without waiting for a response.

“Yes, you may - oomph!”

Flux’s response was cut short, as within the second of him saying she could, Rainbow slammed her hips down and engulfed his cock into her pussy. Throwing her head to the sky, she held her position for a moment. Once more, her marehood convulsed and gripped onto him with astounding force, as she immediately climaxed from his intrusion a second time. Though, she didn’t remain still for long, and soon after she began to wantonly screw herself on him.

Flux savored the warm, taut depths embracing his cock. Her expression was one of uncontained, unrelenting pleasure, as her tongue hung out and her eyes rolled back. She worked his cock like the seasoned whore she truly was deep down, and throughougly milked his cock properly. She wasn’t too familiar with sex, always restraining herself due to her immense social status and pride, but she served his tool like a professional slut. Be it her body subconsciously remembering their past romps, or some deep latent part of her that was designed to be bred, she properly clenched on her upstrokes and relaxed on her descents. Though her face was one of immeasurable ecstasy, Flux wanted to push her even further beyond the realm of nirvana itself. Summoning magic in his horn, he shrouded her perky bosoms and sensually tugged and twisted her erect nipples.

The addition of her tits being stimulated sent Rainbow into a frenzy. Slamming herself down with every ounce of her energy, she fucked herself on his cock without restaint. Her ass jiggled with each descent, her tits bounced, and sweat dripped down her form. Her wings extended, and she began to flap them to add to her efforts, raising herself slightly higher and slamming down even harder. His medial ring teased and taunted her g-spot, furthering the pleasure she was enduring. Orgasms rocked through her at a rapid fire pace, and she continually waded in and out of consciousness.

“Mmmph! Thank me for my cock! Thank - nngh - thank me for treating you like the slut you truly are!” he croaked, struggling to restrain a flurry of moans attempting to escape him.

“Thank you! It feels so bucking good! Thank you! Thank you thank you thankyouthankyouuuuuuu!!!”

Though she hadn’t expected it, this time Flux graced her confines with his seed. Boiling hot semen surged into her in ropes, and the sensation of his foal-batter filling her wrought a cataclysmic blow to her sanity. Any pitiful remnants of her ire were now extinguished entirely, and she felt a sense of fulfillment within her. The climax she experienced was beyond any she had ever experienced in her life, and she threw her head back in a noiseless scream. Gripping her hips, Flux held her in place as he dumped loads of his essence into her constricting confines. Her walls milked him dutifully, eager and desperate to get every last drop.

“Gah! Ahhn! Yessssss! You’re so fuckinggood!”

Flux laid back entirely, relaxing his breath and gasping for air momentarily. Through all his times with Rainbow never had she been this eager. He thought their last time, which he had viewed recently on his recording tape, would be the pinnacle of their sexual adventures, but he was wrong in the most wonderful way possibly. He craved her body, and at this point, she was all his. Reaching the end of her orgasm, she gave one last intense shudder before falling forward, resting her head beside his. Both ponies lay there for sometime, breathing heavily onto one another. Flex reached his hoof down, caressing Rainbow’s flank as he gently pressed against the soft, plump region.

“You want more, Slut?” he questioned, feeling her stir beside him.

She pressed her rear back, pushing his cock into her depths again as his cum gushed out of her. Slowly, she brought her face in front of his, staring into his eyes with her own.

“So, is that a yes or - mmph!”

For the second time in short order, he was cut off by a sudden action by Rainbow. Pressing herself forward, she brought the unicorn into a deep, passionate kiss. Dueling his tongue with her own, she began to rock her hips back and ride his cock once more. Feeling compelled to oblige her, Flux met her downstrokes with his own thrust upwards, fucking her whilst holding her in an intense embrace. For what felt like hours the two dueled with their bodies, moaning into each other’s mouths with unrefined lust as they fucked one another. Pausing her efforts, Rainbow pulled out of the kiss, giving a deep, lustful moan.

“Please…I need more. I - unf - just can’t get enough. This heat. This need. Ahn! Sweet Celestia, you’re so bucking good. Ahn! F-fuck! Ah! I…I have to have more of you. Mmph - s-so good! I don’t care what you want - nngh - please just rut me more.” she admitted, panting between her breaths.

Flux could feel her desire. It was the most pure, uncontained need he could even imagine, and he knew it was his time to strike. Pausing his own motions, he caressed her face, covering his hoof in her sweat. “I can fix this all for you Rainbow. Give you all the pleasures you can imagine and more. That heat of yours? It won’t ever go away, but I can help make it…easier ~”

Rainbow stared at him with a mixed expression of confusion and lust, trying and failing to understand what he meant. “H-huh?”

“You know you’re a slut, deep down you always were, so, why not embrace it entirely?” he continued, dragging his hoof under her wing and around her waist, causing her to release a moan.

“I…I’m not really…”

“Yes you are. You know you are. Look at you, practically dying for my cock. Accept it.” he interrupted.

Gulping, knowing he was telling the truth, she rubbed her slickened marehood against his crotch. “H-how…how can you make it easier…”

“Simple. You just embrace what you’re truly destined to be -” he coolly responded, shrouding her tits in his magic once again, “my slave.”

Rainbow’s eyes fluttered for a moment, as the teasing on her tits struck another blow against her logic. Shaking her head, she forced together all the fibers of her past self in an attempt to retort.

“N…no I - I can’t - aaaahn,” she whined, extending her wings and flapping them excitedly.

Shifting her body back on top of his cock, Flux tore apart her attempt of a retort. Though there was a small remnant of herself screaming and insisting that she deny his statement, she found the words locked away. The sensation of what he could do to her, and just how divine it felt, demolished the attempt she made to save face. The pleasures he gave her were beyond her wildest dreams, and everything he said to her, even if she hated to admit it, was true.

This heat seemingly would never go away, and with her biological impulses constantly in overdrive, she needed him more than anything. She could go back home, try and put this behind her, but she knew she would never be able to get him out of her mind. Her clit winked whilst embracing his cock, and she brought her head back down to face him. Staring at him with a lust-crazed glare, she began to pick up the pace at which she rode him.

“You were saying?” he mockingly asked.

“Nnngh! Ah! Y-yes! I’ll be your slave! Anything! Tell - unf - tell me what to do!” she wailed, wantonly fucking herself on him once again.

“Get off of me, and I’ll explain,” he explained, watching as she hesitantly slowed to a halt. Taking note of her crestfallen expression, cleary desperate to continue her fun, he caressed her face once more, “Don’t worry, after you fully embrace what you are,” he leaned forward, whispering into her ear, “I’ll fuck you so hard you won’t be able to walk normal for days.”

Nodding in understanding, nearly drooling from his words alone, Rainbow slowly pressed her hooves against the ground and dismounted off of him. His stallionhood slipped from her depths, coated in the mixture of his cum and her juices. Eyeing his cock, Rainbow’s eyes went wide in realization. Stooping back down, she took it into her mouth and slurped on the rod.

“Good slut, already remembering your orders. Seems like you were made to be my personal little fuck-toy ~”

Rainbow didn’t reply, not vocally at least, simply opting to look up at him and nod. She worked his cock thoroughly, hungrily lapping up each glob of cum that remained on him. Her marehood continued to wink, letting more of his cum gush out of her dampened nethers. She’d lap it up from the floor later, at least she hoped he’d let her, since the taste of his essence on her tongue was better than anything she had ever tasted. The salty, yet rich flavor brought a taste to her palette unlike any other. Popped his cock from her maw, she slid her tongue up and down the thick flesh of his shaft, hungrily lapping up every delectable flavor along it. Reaching his tip once more, she swirled her tongue around it, before finally releasing his member entirely.

“Good girl,” Flux complimented, making Rainbow’s heart flutter. “Now, here’s how this will work.”

Summoning his beloved tome to his side, he flipped to Devotionis Vestigium’s entry. Rereading the entry, he made note of its requirements and looked over at the quivering pegasus before him. His cum and her nectar were forming in a pool below her, as she nervously looked away from him and to his cock. He knew part of her feared what was to come, but she had lost the battle the moment she stepped hoof in front of him.

Summoning magic into his horn, he began. “This right here is a special little spell, named Devotionis Vestigium.” Trotting around Rainbow, taking note of her eyes remaining fixated on his stallionhood, he continued. “Essentially, it is a will-binding enchantment.”

Snapped temporarily from her stupor, Rainbow questioned him. “W-which means?”

Pausing his walk, he threw a wolfish grin towards the mare. “It means that if I successfully cast it upon you, you will be bound to me as my slave forever.”

Rainbow gulped nervously, though her cunt gave an excited wink. Damn her if she knew why or how the prospect of being his slave sounded so arousing, but it did. Knowing the unimaginable bliss he could dispense upon her, being bound to him would ensure she’d get fucked all the time.

“A-and that’d mean…” she nervously pressed.

“You will obey everything and anything I tell you to do. Oh, and you’ll only be able to find true pleasure from me and me only. You will act how I please, do what I please, wear what I please, help me with what I please, and more. Of course, it comes with countless benefits.”

“L-like?”

“Well, for one, every single time you obey a command of mine, you’ll receive a wonderful surge of pleasure. Not only that, but that heat of yours? I’d be able to alleviate you from it, at least temporarily. Though, maybe you like how good it feels to be fucked senseless while its surging through you ~ “

Rainbow tried with all her might to find a reason, an idea, any words to deny her wants, but she couldn’t. She simply couldn’t imagine living with this endless need, she couldn’t imagine going on without having a cock in her every single day, she couldn’t imagine going forward in life without him. What he demanded of her defied everything she ever stood for. The Wonderbolts would certainly be a thing of the past for her, no matter how hard she tried. The heat within her made it impossible to focus, and not only would she be slower, but she was confident her teammates and anypony else would notice the heavily dampened portion of her suit her pussy would without a doubt create. Her role as an Element would positively be affected too. She’d be owned by him, a villain, and with that meant she’d certainly have to assist him with whatever plans he’d form. Though, a part of her felt conflicted. She’d still be loyal, but not in the way she always had been. Not loyal to the Wonderbolts, not loyal to her friends, not loyal to Equestria, but loyal to him and him only.

“Here’s some…encouragement for your decision ~” he cooly added, shrouding her tits and clit with his magic.

The immediate pleasure overrode any thoughts she had. Bucking her hips back, feeling her winking, needy cunt press against the cool air, she released a wave of throaty moans. She couldn’t deny it, not anymore. Her biology as a mare, her deep degrading kinks, her heat, her pride, weeks of endless estrus, all of it had led to this moment. All of it led to her finally, willingly submitting to the destiny life had provided her. Fuck it, if her fate was to be the wanton fuck-toy of a nefarious villain she once despised, then that was her fate. The pleasures he delivered were unbeatable, not even for her or her near endless ego. He had bested her, to the furthest level possible. She was nothing more than a fertile mare before him, and within moments, that’s all she’d ever be forever onward.

“Y-yes! Do it! Mmmph! Make me your slave! I’m your mare! Ah! You’re just too gooooood! Ahn! I’ll be your fuck-toy! Your loyal bitch! Nghh! Anything for you Flux!” she cried out.

“Master,” he quickly remarked, smiling a wide grin.

Blinking wildly, taking a moment to register his words through her lust, she continued. “Yes! Aaaahn! Master! You’ll be my Master! Ngggggh!! You own me! You’re better than me! Ah! Ah! Ah! I can’t deny it anymore! Please! Please just do it! Oh my goooosh! Mah! Unf! I give all my loyalty to you!”

Aiming the spell at the squirming mare, seeing it shift colors as her end of the bargain was fulfilled, Flux chuckled to himself. “You and I are going to have a lot of fun, Slave.”

Author's Note

Hope ya liked the grand "conclusion" of all this! But it ain't over juuuuuust yet
