Part 2 of https://inkbunny.net/s/3477290, this chapter was split in two due to its length.", "writing": "Locked in complete darkness, I was left to mull over my fate. In my current state there was nothing I could do to free myself - the Caribou were thorough in their work and their devices too solidly built for me to break free on my own. And even if I managed to escape they were still in complete control of the castle, with the treasonous Royal Guard patrolling the hallways and keeping a close watch on every gate. I was left to stew in my thoughts, in my fury, frustration, humiliation, anger and helplessness. But equally and increasingly my thoughts turned to concern for our citizens and those dear to me, such as my sister. I cannot imagine what horrors they must be going through.\n\nThe plug inserted into my anus was evidently inscribed with the same arousal spell as before, and I was soon gripped by desire once more. I cursed the potency of the Caribou’s magic. It forced me into an overpowering state of heat, and I found myself unbearably aroused. I started sweating, and my winking sanctity leaked with shame. As a result sexual thoughts began pervading my mind, which resurfaced no matter how hard I tried to suppress them. \n\nI could only grumble in frustration, unable to relieve my pent up lust in my predicament. Yet I resolved to refuse my carnal desires, knowing that succumbing to temptation would bring me ever closer to defeat.\n\nThe first day of torment was nightmarish. My belly was churning and cramping, the horrific torture made worse by the tight confines of my unyielding restraints. I never quite got used to the liquid filling my intestines, which I could feel sloshing around inside me whenever I attempted to break my restraints. It was an unpleasant sensation to say the least. To my relief the painful cramping subsided somewhat as time went on, although the need to empty myself was ever present. \n\nTo my surprise I experienced neither thirst nor hunger during this time. Whatever fluid was inserted into my digestive tract must have been supplemented with sufficient nutrients to sustain me over an extended period. But little did I know my experience of Tartarus had only just begun.\n\n————\n\nThe next morning I was awoken by the turning of the heavy iron key that unlocked the door to my prison. It was Anvari, who had returned bearing most unpleasant news.\n\n“I trust you had a pleasant night, [i]princess[/i],” he spoke mockingly while inspecting the shackles and leather straps that kept me restrained. “King Dainn has ordered for you to be made into his anal slave. He has recognized your unique physical qualities and has commanded you undergo extensive anal training, so your ass will be put to proper use. As such you will be subjected to the necessary physical enhancements in order to optimally perform your new tasks in life.\n\n“No cock will penetrate your cunt ever again, no matter how much you beg and crave for it - save for at your master’s mercy and grace. As a sign of your new station in life your pussy will be sealed, communicating to all that you are an anal slave and inviting them to fuck your asshole.”\n\nThe bull opened a small wooden box he had brought with him, which contained a set of piercing needles and rings.\n\n“These rings are infused with a magical seal, which can only be broken by your owner’s specific order. Only at his command can they ever be removed,” Anvari continued. “Understand that he holds your fate in his hands. He has complete control over your body and mind, and you are beholden to his will.”\n\nTo my horror, the fiend intended to physically seal my vagina.\n\n“NHHH!! MMGHH!!” I screamed in panic, thrashing wildly against my restraints. \n\nI fought with all my might to break free, struggling against the leather straps that kept my limbs spread wide. Even my wing sheaths stretched and creaked as I fought desperately to prevent the sadist from enacting his appalling plan. But no matter how hard I struggled the bonds would not break. \n\nThe bull poured some liquid from a bottle onto his hands and lathered my crotch with it. It caused a slight tingling sensation, which quickly ebbed away.\n\n“This is both a disinfectant and numbing agent, which will prevent infection and reduce the pain. Regardless, any discomfort will be only momentary,” the Caribou spoke while he reached for his tools.\n\nThankfully the anesthetic worked quickly, such that I could only faintly feel him pinching and tugging at my labia with his fingers. The fact that I was still fully hooded only made the experience worse. I screamed when the needle pierced my skin. Although the pain was only faint, the thought of being disfigured and taken control of in such a manner was unbearable.\n\n“HRRRRGHHH!!” I wailed, as I felt the bull remove the needle from my skin, before realigning it slightly further down. \n\nThe savage worked quickly, immediately pushing the sharp implement through both of my lips once more. It was over before I knew it.\n\n“Stop complaining. It’s only a minor procedure,” Anvari grumbled, while disinfecting and treating the puncture wounds with a viscous salve. “This will speed up the healing process. You’ll be completely pain-free in no time.”\n\nThe fiend then took the two silver rings and carefully threaded them through both of my labia, locking my lips together. As soon as Anvari put the second piercing in place I felt Dainn’s accursed runic enchantment taking hold, cold as the winter’s chill.\n\n“NNHHH!!” I screamed while desperately trying to shake the jewelry off somehow.\n\n“Your cunt looks beautiful like this, slave. These rings will prevent cocks from penetrating your pussy. The gap is large enough for fingers to enter however, in case your master chooses to reward you in such a way,” the bull said as he calmly disinfected his tools before storing them away.\n\nIt was an unbearable insult. Like my collar and wing sheaths it was yet another reminder that I was considered to be little more than property. I was apoplectic with rage, screaming and shouting into my gag while fighting and struggling against the chains and shackles that imprisoned me. I would have eviscerated the Caribou on the spot if I still could. \n\n“In addition, King Dainn has generously bestowed you with a new name more befitting of something of your status. From now on you will be known as Cock Sleeve, and references to your former name have been formally erased from the records,” the brute continued, his voice betraying a hint of glee. “Be grateful for his generosity, for such an honor is only bestowed upon a select few. I gather the populace has reacted with unanimous approval upon being read his royal decree.”\n\nThe disgusting name was grievously insulting, and left me incandescent with fury. Not only would I be made to serve my enslaver in an utterly repulsive manner, my horribly degrading slave name also affirmed my place as one of his sex toys - a humiliating notion I could never accept.\n\n“Most household or cattle slaves are little more than objects that may be replaced at their owner’s whim. As such, names are often not bothered with. Bestowing a slave with a name is therefore a sign of a master’s favor, and a gesture of great generosity,” Anvari said, now turning his attention back towards me. “It shows he considers you of sufficient quality to spend the time and resources necessary to raise you as a proper sex slave.\n\n“Although officially all cunts share the same status as property, exceptional slaves are often selected to made into center pieces in their master’s harem. They become symbols of his status, performing roles in public that show off their exceptional qualities. Please your owner according to his demands, and you may lead a life of pleasure and comfort in his service. Resist, and it will be made as miserable as that of the lowest black collar slave.\n\n“Now then Cock Sleeve, tell me your name and purpose,” the villain spoke, before pulling the penis gag from my throat.\n\nI coughed and retched for a moment, before taking a deep breath.\n\n“I am Princess Luna of Equestria!” I declared defiantly. “I shall never submit to the likes of you!”\n\nThe Caribou immediately forced the phallus back down my throat in response.\n\n“Hmm, just as I expected. That does make this exercise, shall we say…a bit more entertaining,” Anvari spoke, with a hint of deviousness in his voice. “Until you answer me correctly, you will not find relief. As a matter of fact, your discomfort will only increase.\n\n“Your anal plug has a special valve, allowing the injection of additional liquid without first requiring its removal. Understand that you will only know relief from your situation at my discretion, and that you are experiencing but a small measure of discomfort. Obey, and you will be kept in relative comfort. But should you choose noncompliance, each day the amount of laxative added to your enema will increase, and so will the pain you experience.”\n\nThe bull took the clyster syringe’s catheter, connecting it to the valve on my butt plug. I shrieked when I felt the second load of fluid being forced into my bowels, distending my stomach even further. The intense cramps instantly returned as the liquid sloshed around my innards, filling me up more and more as the latex fabric of my suit stretched around my belly.\n\n“NHHHGHHH!!” I screamed into my gag, unable to bear the heinous indignity.\n\n“Exactly how uncomfortable things get is entirely up to you. This is a very simple lesson, cunt. You already know what the correct answer is. I will return tomorrow to see if your attitude has improved,” the vile sadist spoke calmly.\n\nWith that he locked the door behind him. I was left in complete silence and darkness once again, except now my intestinal discomfort had doubled. The cramps were more intense and painful than before, taking longer to abate, not to mention the greater distention of my stomach. I could do little more than suffer through the ordeal, although it was a price I was happy to pay.\n\n————\n\nAnvari was true to his word, only returning the next morning to repeat his insulting question. Again I resolutely rebuked him, and again he injected another syringe worth of fluid into my rectum, further increasing my pain and suffering. \n\nThe bull was both consistent and patient - each day the ritual was played out in exactly the same manner. No matter in what way I repudiated him, he methodically meted out my punishment, greatly increasing my discomfort every time I defied him.\n\nThis routine continued for several days, until by the fifth morning the experience had become excruciating. The horrible cramps were constant and my stomach was hugely swollen by the sheer volume of liquid trapped inside me. By now I was sweating profusely, writhing in agony and overcome with an overpowering need to empty myself. But no matter how much I tried, the accursed plug kept me tightly sealed, preventing any form of relief. Panicked attempts to free myself only resulted in triggering horrible spasms, and achieved nothing but increasing my suffering.\n\nIn addition, my magically-induced state of heat had become unbearable. I was drenched with arousal, leaking fluids and winking uncontrollably. Every movement of my labia pulled against those infernal rings Anvari had pierced me with, a continuous reminder of my disfigurement.\n\nWhen the torturer returned he slowly removed my cock gag, seemingly taking delight in my humiliation and suffering.\n\n“I will ask you again, cunt. What is your name, and what is your purpose in life?” Anvari asked, running his hand over my distended stomach.\n\n“…Hngh…ah…I-I…” I mumbled.\n\nI was loath to suffer more punishment, but I could not bring myself to call myself by such a despicable and humiliating name. Much to my dismay, my momentary silence was enough for the bull to shove the phallus straight back down my throat.\n\n“You will answer immediately and clearly when a male addresses you, slave,” the barbarian spoke sternly. “You would do well to remember this.”\n\n“MHHHH!! HHRRRGH!!” I wailed, straining myself against the following influx of fluid.\n\nIt hurt. The laxative induced horrible, severe cramping in my stomach. My insides were now greatly stretched and distended, and I was absolutely desperate for some relief. The bull was merciless however, injecting the full load of the syringe inside my body and leaving me locked inside my prison once again.\n\nI was now so full that the pain and discomfort did not abate, even after several hours. My innards felt stretched to their absolute limits, to the point that I was certain I would not be able to take another syringe full of fluid. I looked like I was heavily pregnant, to the point that my enormously swollen stomach was splitting the fabric of my rubber suit.\n\nIt was pure suffering. Any sort of movement would send the liquid sloshing inside my bowels, triggering the most horrible intestinal cramps. My absolute state of helplessness was vexing, and the realization that there was no way out insufferable. All this time there had been no indication that help was forthcoming, nor had there been any sign of rescue. My fate was entirely in my torturer’s hands.\n\nBy the time Anvari returned, I was begging for it to be over. I couldn’t take another enema, another day in this Tartarus. No matter how degrading it would be, I had to face the fact that this was a battle that I could not win. For my own wellbeing I needed to relieve myself, urgently.\n\n“Cock Sleeve, my name is Cock Sleeve!” I exclaimed the moment he pulled the gag from my mouth.\n\n“Good girl. Now that wasn’t so hard, wasn’t it?” Anvari spoke with satisfaction. “Now tell me, what are you, and who is your owner? And I remind you to use the proper appellations.”\n\n“I…am…ngh…Master Dainn’s…anal slave…”\n\n“Again, cunt,” the Caribou lord demanded sternly. “State your name and purpose, clearly and promptly, unless you want me to give you another enema.”\n\n“My name is Cock Sleeve, I am Master Dainn’s personal anal slave!” I cried, fearful of yet another day of torture.\n\n“Good girl,” the bull spoke, running his hand from my swollen belly down to my crotch. “Never forget - recalcitrant slaves are punished without mercy. But obedient girls receive pleasure for their submission.”\n\nHis fingers felt heavenly on my touch-starved vagina. By now I was in an unbearable state of heat, and at no point had I been able to satisfy my pent-up desire. I was unable to resist him, neither physically nor mentally. The bull expertly teased my folds, running his fingers along my labia and attending to my clitoris. His experience showed; he effortlessly found just the right rhythm and pressure to make me squeal.\n\n“HHNNGGH!!” I moaned loudly into my gag.\n\nTo my frustration it was an expression of pure, unadulterated pleasure. I hated my failure to suppress my carnal desires. But each time I managed to wrest back some semblance of control, the Caribou’s fingers instantly made me lose it again.\n\nThe orgasms came quickly, and in rapid succession. I cursed Anvari’s ability with his hands. He made me scream like a common harlot when he gently inserted his finger into the gap above my piercings, pleasuring my g-spot like I have never experienced before. With a flick of his finger he was able to drive me to incredible heights of sexual bliss, making me squeal, cum, squirt and convulse over and over again. If it weren’t for the enormous plug lodged inside my rump, I’m sure I would have expelled the fluid right then and there.\n\nAnvari let me ride out my orgasm, enjoying the sight of my trembling body, swollen stomach and heaving chest as I caught my breath.\n\n“Please…ooh…a-allow me to relieve myself,” I asked softly, still panting heavily.\n\n“I remind you that you’re talking to a male, cunt,” the Caribou lord answered sternly. “You will address me with respect at all times. Use the proper appellations, unless you want to stay in here for another week.”\n\n“Ngh…please M-master Anvari, allow this…anal slave to relieve herself,” I begged.\n\nHumiliating as it was, I could only give the bull what he wanted. My body was screaming for release from the discomfort and pain, and I was not sure if I would be able to physically take another enema, not to mention another hellish day locked in complete isolation.\n\n“Hmm, good girl. Despite your attitude I can tell you’re a quick learner. In time you’ll no doubt become one of the most desirable sex slaves in Equestria,” Anvari said, placing a large container underneath my rump. “Now, the men have enjoyed watching you struggle over the past week. Make sure to give them a good show.”\n\nUnbeknownst to me, the Caribou had been recording me the entire time. The images had been broadcast to the populace with the intent of stripping me of all dignity and grace, ruining and twisting my public image into that of a subjugated slave. It hurt me grievously, but I could only fight back the tears as I felt Anvari reach for my anal plug. \n\nThe floodgates opened the moment he pulled the sex toy free from my sphincter.\n\n“Aaaghhh!! Hnnnghh!!” I screamed, as a week’s worth of enemas finally burst out of my body, splattering into the container below me.\n\nUndignified and disgusting as it was, it was a relief to finally have the pressure inside my stomach released. Gradually the flow slowed down to a trickle, and I was left panting on the table while I was unceremoniously hosed down with water.\n\n“This is just the beginning of your life as an anal slave, Cock Sleeve. But before you start your training, you’ll first need to be physically prepared in order to unleash your full potential,” Anvari spoke as I slowly recovered from my ordeal.\n\nI did not understand what he meant, and in hindsight I was glad I didn’t. At the Caribou’s call my handlers entered the room, unlocking my shackles and taking me down from the table. In my exhausted state I struggled to stand and collapsed onto my knees, only being held up by the strong grip of the two bulls.\n\n“Clean her up properly and take her to Lord Hrathr. He should have completed the necessary preparations and will be expecting her,” the Caribou lord spoke while he washed his hands.\n\n“As you command, Lord Anvari,” the men responded, before taking me out of the holding cell to be bathed.\n\nAfter a week spent sealed inside the rubber suit, I stank. Being too physically spent to offer any significant resistance, I was stripped down, washed and shaven. I was loath to perceive it as reward for my compliance, but the bath was a genuine relief and a brief moment of enjoyment after a week of pure torture. \n\nI realized this was exactly Anvari’s intent, and an example of how insidious the slave training techniques of the Caribou can be. By strictly controlling punishment and reward, even seemingly innocuous moments of comfort are used to manipulate their victims, subconsciously molding them into their submissive servants. \n\nBut despite this knowledge, and as invasive as being washed by somepony else’s hands is, I could not help but enjoy the smell of soap, the shampoo in my mane and tail, and the feeling of warm water washing the filth off my skin. It was not to last however. After I was made presentable and had recovered some of my strength, I was lifted back onto my hooves, shackled and marched to a different section of the castle.\n\n————\n\nThe recreation hall was an annex of the palace, where guests used to be entertained and where celebrations were held. The Caribou evidently had other ways of passing their free time, and were in the process of converting the hall into what seemed like laboratories of sorts. New rooms were being constructed, with rows of strange equipment and devices placed throughout. \n\nI was not prepared for the horrific abuse I was about to witness there. \n\nGirls from all walks of life were incarcerated in the labs - from Wonderbolts to guardsmares to ponies who had come from the countryside to try their luck in the capital. Every single one of them had been collared, and had any horns removed and wings sheathed. Some had symbols tattooed onto their skin or had even been branded, presumably to humiliatingly mark them as slaves, indicate ownership or otherwise marking them as property.\n\nNot only had they captured mares, but also the females of the other inhabitants of Equestria such as griffins, buffaloes and even dragons. All were treated equally - as living sex toys, to be used for the enjoyment of the realm’s new ruling class. \n\nAs is the invaders’ wont, all of the captives were completely restrained. Some with shackles and chains, others with intricate rope work or even locked into the machinery. Regardless of the method employed, all of the girls were forced into postures that preserved none of their dignity. Their clothes, if they wore anything at all, were scant in most cases, clearly designed to emphasize their sexual features. The designs made gratuitous use of leather and rubber, and were often mere strips connected by metal rings. Rather than preserving a girl’s modesty, they kept her shame completely exposed, drawing the onlooker’s eye towards her bare crotch, breasts, rump and legs.\n\nMany were being violated in some way or another - some by vibrators held against their private parts, while others were being penetrated by phallic toys mechanically driven by pistons. Other unfortunate captives had suction devices attached to their vaginas which drew out their bodily fluids whenever they climaxed. These were then force-fed to the hapless victims by being sucked up through a tube connected to their mouths.\n\nI saw one Caribou inject a poor mare’s breasts with a serum of sorts. For a moment the girl struggled before her chest swelled up both in size and fullness, growing out several cups. While she was staring in disbelief at her enormously expanded globes, the bull connected two suction cups to her nipples. Milk started flowing instantly, filling up the tubes and pouring into a large holding tank behind her.\n\nThere seemed to be no end to the unspeakably depraved sexual contraptions the Caribou had devised. I observed strange machines driving what looked like large spheres into an enslaved dragon’s rump, causing her to cum and squirt wildly. Inside another cell a luckless buffalo cow had been heavily restrained, and seemed to have electrodes attached to her breasts and crotch. Other mares were being pumped full with substances flowing from holding tanks and intravenous drips. \n\nWhat seemed to be happening in these laboratories were horrific, immoral experiments, aimed at manipulating the minds of slaves as well as enhancing and augmenting their bodies, so they could better serve their purpose as sex objects. Some were aimed at modifying a captive’s physique, creating an idealized, sexualized figure to sate her master’s perverted fantasies. Yet others featured machinery connected to their hapless victims’ heads, suggesting they were undergoing some sort of mental manipulation. Presumably this was a form of brainwashing, enabling the Caribou to better control their subjects.\n\nTreatment such as this is abhorrent, barbaric and uncivilized, not to mention a gross violation of a mare’s right to control her own body. But it is nothing out of the ordinary for creatures as vile and despicable as the Caribou, and just one of many terrible examples of sexual abuse that I would witness that day. My heart went out to these unfortunate victims, and I deeply regretted by inability to intervene and put a stop to the proceedings. But chained as I was I could do little to alleviate their suffering. A quick stab of the cattle prod and a tug on my leash reminded me to keep following my handlers down the hallway.\n\nEventually we came to a confluence in the path, where we were met by another Caribou lord. Hrathr was his name, and he was a large, muscular brute of a bull. He was an imposing figure, taller and broader of frame than Anvari, but going by his balding head and the wrinkles in his face he was well into middle age. Despite his years he was a beast master by trade, and it showed - his arms and face bore numerous scars, and one of his antlers had been partially broken off.\n\n“Greetings Lord Hrathr,” one of my handlers spoke after saluting the elder bull. “Lord Anvari sends you this slave, as was commanded by King Dainn.”\n\n“So this is the younger sister,” Hrathr spoke, eying me up as if I were a piece of meat. “A mare of fine quality indeed. We’ll make a proper sex slave out of you yet.”\n\n“Do your worst, slaver. But do not think a princess of Equestria will fall so easily to the likes of you,” I spat at the savage in disdain.\n\n“Hmm, I was told of your recalcitrant character. But despite your upbringing you’ll soon find that you’re a cunt like any other,” Hrathr answered bemusedly. “Come and see for yourself.” \n\nThe beast master rudely yanked me by my leash, dragging me to a nearby room. When I peered through the window I stood frozen in shock.\n\nBehind the glass pane of the isolated cell I could see my sister, buck naked and trapped on all fours in a contraption that completely immobilized her arms and legs. Her head was covered by a helmet and her eyes by a visor; a mask sealed her muzzle and fully enclosed her visage in rubber. But I could tell from the colors of her mane and tail that it was unmistakably Celestia. \n\nShe had been dehorned as I was. The thick black collar of a Caribou slave was clasped around her neck, complemented by the same torturous black wing sheaths that I had been forced to wear. To my horror, her cutie mark had been defaced by a brand resembling a pair of chains overlaid on her Sun, a permanent, physical reminder of her captivity. A fiendish sex device was desecrating her from behind, mercilessly thrusting a pair of large dildos in and out of both of her holes. She looked completely disheveled, and her body was covered in sweat. My sister had evidently been locked inside this torture chamber for days on end.\n\n“Tia! Tia!” I exclaimed in dismay. “What are they doing to you?!”\n\nI banged on the window separating us but the material dulled the sound, and the device locked around her head prevented my voice from reaching her ears.\n\n“You waste your time, cunt. We control all of her senses completely - what she sees, hears, smells, tastes, feels and even when she cums,” Hrathr spoke. “She is the king’s private property now, and is being prepared for her new life as his sex slave.”\n\nFrom the multitude of screens mounted on the walls around Celestia I gathered that she was being subjected to a thorough mental conditioning regime. The Caribou were keeping a close eye on her vital signs, monitoring and manipulating her hormone levels and mental state. Through her visor the fiends were projecting perverse imagery onto her eyes; many wires were connected directly to her helmet, stimulating her brain in order to twist and corrupt her in insidious ways. Part of the helmet’s design covered Celestia’s ears, and additional wires connecting to the machinery beside her seemed to indicate that she was being indoctrinated around the clock. \n\nSeveral cameras recorded the process from various obscene angles, preserving none of my sister’s dignity. Behind her I saw a large holding tank containing a disgusting, viscous fluid. From what I could make out from a label stuck to the glass, it was the sperm of war beasts. The container was connected to her mask by a large tube, which was joined by smaller tubes connected directly to her nostrils, controlling her intake of air and scent. \n\nI cursed my powerlessness as I beheld the horrifying scene. Disconcertingly, a pool of liquid between Celestia’s legs showed that perhaps she had enjoyed herself a little too much.\n\n“King Dainn has special plans for this bitch. Like you she is an exceptional beauty, and possesses prodigious talent,” Hrathr said, observing the proceedings with satisfaction. “Although she resists, she lacks your stubborn predisposition. Through guidance from a firm hand and the right teachings she will become an extraordinary sex slave.\n\n“As a fresh cunt she has much to unlearn, but she is proving herself to be quite receptive to our teachings. She will be trained to the very highest standards - nothing but perfection will be expected from the king’s fuck pet. Sun Slut is her name now, although I hear some guards enjoy informally using the nickname Cuntlestia, in mockery of who she once was.”\n\n“Her name is [i]Celestia[/i], and she will never break! She is a princess of Equestria and will never submit to the likes of you!” I spat at the beast master, disgusted at the preposterous notion that my sister would ever willingly kneel before him.\n\n“Hmph, you think too much of your whore of a sister. Pleasure is both a powerful teacher and master, and it’s obvious that she enjoys her treatment,” Hrathr retorted. “Observe closely, as she is reduced to little more than a whore.” \n\nAs I was forced to watch Celestia being violated, I could see her…starting to grind her hips backwards, receiving the twin sex toys with vigor. As far as I could tell, she was moving out of her own volition, harder and faster with each thrust. She arched her back, throwing her head back in passion…was she…truly enjoying this somehow? Then suddenly I could see her body tensing up, before starting to shake and tremble violently. The cameras captured the jets of liquid squirting from her crotch, splattering on the floor behind her.\n\nMy sister was orgasming wildly.\n\nIn the midst of her climax, the semen inside the tank was pumped through the feeding tube connected to her mask. Celestia struggled and strained as the revolting liquid poured into her mouth. The Caribou were force-feeding her war beast sperm right at the moment of orgasm, manipulating her mind into associating its taste and scent with pleasure. For a moment my sister seemed to resist the flow, attempting to dislodge her feeding tube by shaking her head. The device did not allow for any overflow however, and I soon saw her throat distend as the liquid was forced down into her stomach. The flow was relentless, and she soon accepted her feed, actively gulping down her reward.\n\nAnd through it all, I could tell that she was cumming and cumming.\n\n“Little by little, every orgasm rewires her brain and ingrains her lessons deeper and deeper, gradually molding her into a maximally submissive whore. Much of her resistance comes from unfounded notions of dignity, modesty, customs and manners. But deep down she has all the makings of a depraved slut,” Hrathr spoke. “In time we will be turn her into one of the finest sex slaves in Equestria, famed for her physique, obedience and sexual prowess.”\n\n“No! Celestia! Fight it sister!” I screamed desperately, banging on the glass.\n\nBut she was in the throes of lust, and the infernal device covering her visage prevented her from hearing me. \n\n“Down, cunt!” Hrathr shouted as he yanked me away from the windowpane with a powerful tug of my leash. “It’s time to prepare you for your new station in life.”\n\nI screamed and kicked as the brute dragged me away down the hallway. Catching one last glimpse of my sister, I couldn’t help but anguish over the horrible fate that had befallen her. Her body was now slumped over, still shuddering as she rode out her climax. I could tell she was exhausted, but the machine was unrelenting. The cycle restarted and I could see the pistons starting to move again, picking up the pace as they plunged in and out of her sanctity. Suddenly Celestia contorted her tortured body, as if she struggled against a sudden impulse of sorts - but what was happening to her I could not tell.\n\n————\n\nHrathr forcibly marched me to another room on the far side of the hallway, easily overpowering my attempts to fight him off. Despite my struggling he shackled me eagle spread to two vertical wooden bars set about a leg’s width apart.\n\n“Release me you wretch!” I screamed at him, intent on showing the savage he would not find me easy prey.\n\nThe beast master ignored me, taking a large glass cylinder off a shelf on the wall. It contained what looked like a green amorphous blob, slowly moving around a transparent but viscous liquid.\n\n“This slug is a parasite that requires semen for its survival and reproductive needs. It normally infests female war beasts, but in the absence of one any female may serve as its host. Normally it will seek to penetrate the vagina, but alternatively the anus will serve just as well as a point of entry,” Hrathr spoke as he twisted the cap of the container. “Once the slug nestles inside you it will gradually fuse with your body, effectively becoming a reproductive organ that drives you to relentlessly seek out cum. It excretes powerful sex hormones which will modify your physique and behavior, turning you into little more than a sperm receptacle with a strong affinity for war beast cock.\n\n“If nothing else, it’s a suitable fate for a slave of your name, Cock Sleeve.”\n\nHrathr twisted the cap, opening the container to set the creature loose. It was a large, disgusting, elongated slithering thing, covered in many small ribs, nubs and tentacles. A slimy ooze continually seeped out of its pores as it moved, filling me with revulsion.\n\nWithin moments the gelatinous blob seemed to sense my presence, guided by its feelers detecting my scent. The Caribou lord then approached me with the jar, allowing the slug to climb onto my leg.\n\nFear and panic set in the moment I felt the parasite’s cold body latch on, its slimy foot firmly gripping my skin. I thrashed about wildly, screaming as I tried to shake the creature off of me. But it stuck tightly to my body, and my movements only seemed to stimulate it to seek out my orifices.\n\n“No! No stop! You cannot do this to me!” I cried, but my pleas fell on deaf ears.\n\nDisregarding my screams and struggles, Hrathr turned on a large monitor on the wall in front of me. To add insult to injury the sadistic brute had placed a camera on the floor behind me, which was zoomed in on my rump. He was going to make me watch the ordeal from up close.\n\nGripped by terror, I could only watch while the slug slowly but unrelentingly slithered up my leg. My body was shaking, and breaking out in cold sweat. I whimpered as the creature probed my sealed vagina. It was cold and slimy to the touch, and altogether most disagreeable. But the gap left by my piercings was too small for the parasite to fit through, and it quickly turned its attention towards my anus. \n\nI shrieked as the creature now started probing my rectum, sending out its tentacles to search for a way into my body. I clenched as hard as I could, desperate to keep the slug out at all costs. But it was covered in mucus, and after a few exploratory touches to find its point of entry, forcibly slid into my rump. \n\nIt was a horrifying feeling. The parasite was cold and slippery, and despite my best efforts it wriggled itself inside my anal cavity with a few pulsating contractions. \n\n“NO! NOOO!!” I screamed as the parasite slowly slithered up my bowels.\n\n“That’s it, fight it as much as you can, cunt. It’s pointless,” the sadistic fiend spoke. “These parasites have evolved to overcome a struggling host. The more you resist, the more it will excrete a muscle relaxant in its mucus, facilitating its entry into your body.”\n\nTo my horror, the Caribou was right. Each time I pushed the disgusting creature out of my body, it repeated its attacks with renewed vigor. Each time it felt slimier, only adding to the lubrication of my anal passage and making it ever harder to stop it from penetrating me. On the screen I could see I was starting to fail to expel the slug entirely, as my weakening sphincter no longer had the strength to push it out completely before it resumed its attempts to invade me. \n\nThe creature was now sliding deeper and deeper inside me with every attack. I was soon panting heavily from the strain, fueled by fear, adrenaline, and an absolute refusal to be desecrated in this manner. But the parasite was equally unrelenting in its pursuit of claiming me as its host, and it soon exhausted me enough to keep most of its body inside me no matter how hard I tried to push it out. Despite my spirited resistance the revolting thing was gradually and inexorably winning the battle.\n\nSeemingly noticing it was close to overcoming my resistance, the slug’s pulsating movements suddenly increased in intensity and vigor. Taking me by surprise, it succeeded in wholly slipping itself inside my anus. It was horrifying to see the entire thing disappearing up my rump. I once again tried to expel it, but the strain had taken a physical toll on me. I was tiring, and only succeeded in pushing out the back end of the parasite this time.\n\n“No, no! Please, take it out! Please!!” I wailed loudly, realizing I was helpless to stop the slug from embedding itself inside my body.\n\nOur tug-of-war would not continue for much longer. With yet another vigorous wriggle the creature again forced itself into my bowels, but now the combined effects of exhaustion and the muscle relaxant were too much for me to overcome. I screamed at the top of my lungs as I saw the tail end of the parasite disappear inside me, and my sphincter close up behind it.\n\n“NOOOOO!!” I screamed in panic, much to Hrathr’s delight.\n\nTo my dismay, I could feel the parasite mercilessly sliding its way up my rectum, every inch of the way.\n\n“A wonderful feeling, don’t you agree?” the beast master spoke. “The slug’s mucus is a powerful mutagen. As you have now become the parasite's permanent host, it will now start to modify your body to suit its needs, and adapt and prepare you for your life as a war beast cock sleeve.\n\n“It’s transforming the lining of your intestines, rapidly forming new nerve endings and rewiring your nervous system. Your digestive tract will become highly sensitized, allowing you to derive intense sexual pleasure from it, including your mouth. Like your asshole, your lips and tongue will become even more sensitive than your clitoris. Your throat will effectively become a second pussy, resulting from the growth of nerve endings and a complete suppression of your gag reflex.\n\n“Simply put, it’ll soon be far more enjoyable for you to be fucked in the ass and mouth than it ever was vaginally. \n\n“Once fully established it will be an integral part of your body. Surgical removal, even if it were possible, would result in death, since over time the slug’s tissues become extensively intertwined with yours. You will exist solely to provide the parasite with its needs - in return it’ll supply you with the energy you need to thrive and survive.”\n\nI wailed frantically in terror, but strain as I might I was no longer able to expel the creature from my fundament. It kept making its way upwards, slithering from my rectum into my colon. The Caribou, seeing that the parasite had successfully lodged itself inside of me, then blindfolded me.\n\n“Enjoy this, Cock Sleeve. Rejoice, for you will be made anew and be all the better a slave for it,” he said before leaving and locking the door behind him.\n\n————\n\nIn the darkness, I became aware that my body was changing.\nDeep inside me, the creature was releasing large amounts of hormones designed to modify my physique and manipulate my mind.\n\nI was almost hyperventilating, trembling with shock and fearful of what I would become. I could feel the slug twisting my body and invading my mind; over time these alien sensations became ever more pronounced and intense.\n\nSlowly but surely strange thoughts and cravings started to enter my mind, replacing the sensation of horror. At first they were momentary pangs of desire and lust, but soon they developed into a strong need to have my rectum and mouth filled. Realizing the parasite was rewiring my brain, I refused these perverse fantasies as much as I could. But the more I repressed them, the more intense these feelings became, until I could no longer focus on anything else.\n\nI started hungering for sperm, experiencing an overwhelming need to taste it, to savor and swallow it. I wanted to have my mouth and throat filled with cock. I lusted for its taste, scent and shape. For the first time in my life I craved for something, anything, to ravage my rump.\n\nAnd all the while the sensitization of my body continued. I was soon able to notice even the tiniest twitch, wriggle and pulsation from the slug within me, and to my horror its touch was starting to feel pleasurable. My anal cavity was becoming highly sensitive, and to my consternation it wasn’t long before I also started noticing the effect inside my mouth. The slightest brush of my tongue against my lips or palate resulted in ever increasing sexual pleasure, which worryingly was accompanied by a corresponding increase in libido.\n\nAt the same time, the parasite started developing my hips in order to attract war beast males, and to make me physically capable of taking their enormous cocks up my rear. The hormones the slug released were gradually forcing my hips to widen and my rump to flesh out, perversely sexualizing my body for both men and the animals’ pleasure. \n\nIt was both horrifying and terribly humiliating. But worse than my physical corruption was my complete powerlessness to stop it. Although I was in full command of my faculties, there was nothing I could do to stop the slug from taking control of my senses, urges and instincts. It was slowly but inevitably twisting me to serve its purpose. I no longer had a horn, no magical abilities nor a dream world to escape to. Consumed with lust, I started experiencing feral impulses that became less distinguishable from my own thoughts and desires as time went on.\n\nI could feel my vagina throbbing. My nipples and clitoris were fully engorged, and my body was screaming for pleasure. This unnatural state of estrus was so intense that I felt like my body was on fire. I was sweating and dripping with pure sexual craving, aching for some relief.\n\nThen, Dainn appeared before me.\n\nI could smell his cock. His musk triggered an overwhelming sexual response in me, unlike anything I had ever experienced before. It aroused me to no end, and before I knew it I was winking and squirting, hoarsely inhaling his pheromones like a perverted animal. The parasite was altering my senses and taking control of my mating instincts.\n\n“Hnngh!! Oooh!” I moaned uncontrollably.\n\nIt was uncouth and highly undignified, but my desires of the flesh completely overrode any rational thought. Try as I might, I could not wrest my mind from Dainn’s penis. I needed him inside of me. I needed his sperm.\n\n“Good. You are ready to be imprinted, my slave,” the fiend spoke. “It seems like you are particularly compatible host, highly responsive to the physical and mental changes induced by the parasite. It will shape you into an exceptional anal slave once it is fully established.\n\n“But as your master I demand more from you. Although you will always crave war beast semen, after implantation there is a short window during which the slug, and by extension its host, can be specifically imprinted on any male’s sperm. This provides the parasite with additional energy during the infestation process, resulting in more vigorous growth and more thorough modification of the host female.\n\n“The process will fully realize your talents and chain you to me on an instinctual level, turning you into the sex slave you were always meant to be.”\n\n“Hnghh…how dare you do this to a princess of Equestria, you scoundrel!” I managed to snap at the usurper in a brief moment of lucidity. \n\n“You are a princess no longer, Cock Sleeve,” Dainn spoke sternly. “You are a sex slave, and as such you are my property. As your owner I can use you however I see fit. You would do well to remember this.”\n\n“Never…ooh…you’ll never be my master!” I spat at him as I tried to calm down my breathing.\n\n“Many fresh cunts start out with your resistive and recalcitrant attitude. Few manage to maintain it throughout the process of training and reformation. How long will you last, I wonder?” the barbarian chieftain spoke mockingly.\n\nDainn reached for my face, scratching me behind my ear as if I were one of his pets. I shook my head in refusal of the Caribou’s advances, which merely seemed to entertain him. Sliding his hands along my curves and down my body, the savage grabbed a good feel of my rump. I hated myself for letting out an audible gasp in response. To my disgruntlement, it felt good.\n\n“Mmh, you’re starting to fill out nicely, Cock Sleeve. Once the transformation is complete you’ll be a sight to behold,” Dainn commented, slapping me on the cheeks.\n\nThe idea disgusted me, but I could do little more than attempt to control my urges. I was in the close presence of a male, and the parasite was doing its utmost best to compel me to mate with him. It was modifying my senses, making me more acutely aware of his scent and pheromones. I could feel a strong attraction to him, a deep craving for his body which became harder to resist by the moment. A puddle of my shame was pooling between my legs. I was soaking wet, and the warlord knew.\n\n“Haaahh!! Hnnngh!!” I moaned involuntarily as he reached his hand between my legs, running his fingers along my sex.\n\nIt felt incredible. To my consternation, the sensitization process was progressing quickly, allowing me to experience extraordinary levels of pleasure. For a moment I tried to fight my traitorous body, but it was of little use against the bull’s skilled fingers. Nothing I did could dislodge him or otherwise prevent him from drawing out several loud moans, and to make matters worse the Caribou lord soon started focusing his attention on my love bud.\n\nHis touch felt heavenly. I am ashamed to write that Dainn quickly reduced me to a moaning, horny mess. I lost complete control, grinding my hips against his slick fingers; the bull for his part read me like a book, feeding off my reactions to pleasure me just the way I liked it.\n\nIt wasn’t long before I climaxed. My body tensed up and my mind went blank as waves of pleasure completely overwhelmed my body, leaving me screaming, shaking and squirting wildly. Dainn left my shuddering body hanging limply from my shackles while I experienced pure sexual bliss.\n\n“Beautiful,” the Caribou commented. “You’ll be the envy of the nation with a clitoris like this.”\n\nStill panting heavily and slowly coming to my senses, I was not sure of what he meant. But when he removed my blindfold, I could only watch in shock when I saw what was happening to my body. Under the effects of the parasite’s hormones my love nub had hugely swollen, emerging fully from my clitoral hood and jutting outward from my labia. How he could consider such grotesque deformation to be beautiful was beyond my understanding. \n\n“N-no, no! This cannot be true!” I cried, fighting back the tears in disbelief.\n\n“Modification of the host’s sex organs is part of the bodily changes the parasitic infection induces. The slug requires large amounts of semen for its nutritional needs, and it’s therefore in its interest to transform you into an insatiable slut. An enlarged, highly sensitized clitoris is but one of the methods it employs to turn you into a nymphomaniac unrivaled in sexual appetite. Fortunately we have the tools to use this to accelerate your development into an exceptional anal slave,” Dainn spoke while reaching into his pocket. \n\nHe revealed a smooth silver ring that despite its rather simple appearance emanated the chill of powerful Caribou sorcery. It made me shudder to think what horrible, corruptive enchantments it had been infused with.\n\n“This ring is imbued with my personal magic - a spell of control, as well as one of arousal. It will inhibit all clitoral and vaginal orgasms without my express permission, and will keep your body in a heightened state of heat. From now on, anal sex will be your primary form of relief,” the warlord said, before pushing the ring against my swollen clitoris.\n\n“No! No please!” I wailed, exasperated at this unexpected act of cruelty.\n\nBut there was no escape, no matter how much I twisted and struggled to shake the fiend off of me. His fingers had left me completely slick, and the ornament easily slid over my swelling love bud.\n\n“Noooo!!” I screamed, desperately trying to shake of the ring somehow.\n\n“It’s futile, Cock Sleeve. As your body develops and your clitoris grows, this ring will be permanently locked in place,” Dainn spoke with satisfaction. “Consider this a gift to you as my slave. It will serve as a permanent reminder of your status as my sexual servant, and a sign of my favor.\n\n“It will aid in your transformation over time, and will mold you into a magnificent anal slave.”\n\n“Never! I will never be your anal slave!” I screamed in absolute rejection of the notion. \n\n“On the contrary, your development is already well underway. You are mine now, cunt. You serve only a single purpose now, to be fucked in your mouth and asshole,” the fiend spoke as he moved behind me. “But don’t worry. It will be a uniquely pleasurable experience.”\n\nI felt the savage’s hardening penis press between my cheeks. My conscious mind was utterly repulsed by him, but my carnal instincts were now completely controlled by the slug. My body craved his cock, and to my great shame I felt myself involuntarily pushing my rump against it while I winked and squirted uncontrollably.\n\n“Good girl, Cock Sleeve. Looks like your asshole is ready,” Dainn spoke gleefully, guiding the tip of his member to my sphincter.\n\n“No!! Don’t you dare!!” I shouted at the Caribou.\n\nIt was of little use. With a powerful thrust of his hips the bull forced his erect manhood inside me up to its hilt, filling and stretching me to my limit. \n\nTo my surprise, his shaft easily slipped inside my rectum. The initial shooting pain of anal penetration turned into sexual pleasure almost instantly, and I could feel every little bit of his huge cock moving inside me, from its ridges up to its flaring tip. And I am loath to admit that the feeling was exquisite - it felt as good as vaginal sex, if not better. \n\nDainn was fully aware of this. What little resistance I could muster withered away instantly when he started rhythmically pounding my rump, to my begrudging delight.\n\n“Aaahn! W-what…ooh…is happening to me?” I exclaimed as the Caribou quickly reduced me to a moaning mess.\n\n“Feels good, doesn’t it? The slug greatly sensitizes its host’s intestines and further modifies your perception of anal penetration, allowing you to feel enhanced pleasure. In addition it mutates the lining of your bowels, forcing it to produce lubricant to facilitate anal penetration,” Dainn answered. “The speed of your physical development defies my expectations for you, cunt. It seems like you’re uniquely compatible with the parasite. You were truly born to become my anal slave.”\n\nI could barely formulate a response. I found myself almost thrusting my hips back onto his cock as hard as he was fucking me, losing myself completely in sexual ecstasy. It was intense, instinctive, almost feral. And it was equally enjoyable for the bull. He reached for my breasts, groping and fondling me as he grunted loudly. The warlord fully indulged in my body, gradually pumping his cock harder and faster; I soon felt his tip expand, stretching my insides even wider apart. \n\nThe Caribou came with a loud roar, gripping my body firmly and repeatedly hilting himself inside me. The feeling of Dainn’s pulsating cock ejaculating his filth inside me triggered an orgasm that I can only describe as otherworldly. I was overwhelmed with sheer sexual joy combined with a feeling of intense fulfillment and bliss, such that it left me moaning, screaming and gasping for air. My whole world shook and trembled as I squirted wildly. Raw pleasure overloaded all of my senses, and I lost consciousness.\n\n————\n\nWhen I came to I found myself once again restrained in complete darkness. I was lying on the floor with my wrists and ankles tightly bound together behind my back with rope. A penis-shaped gag had been locked inside my mouth, which reached deeply down my throat. My head was covered by a hood, isolating me from my surroundings - it was in this helpless state that I was left to experience Tartarus. \n\nHaving been fed by Dainn, the slug was now growing in strength and vigor. It was no longer moving but focusing its energies on fusing with my body, spreading its tendrils throughout and effectively becoming an organ with me. And all the while the parasite continued to release large amounts of developmental hormones, which raged within me and further transformed my physique to suit its purpose.\n\nTo prepare me to mate with the giant war beasts, the slug was further altering the bone structure of my hips as well as the size of my rump, ruining my physique and leaving me with a perversely voluptuous figure. I could feel my clitoris throbbing and swelling - Dainn’s ring gripped me tighter and tighter as time passed, until the ornament was completely locked in place. My lips, mouth and tongue were continuing to develop in sexual sensitivity as well. As a result I soon found myself begrudgingly enjoying having my throat stuffed by the large rubber sex toy.\n\nThroughout the entire ordeal, my state of arousal only increased. I struggled to resist the creature’s directive - a powerful, instinctive urge to have my mouth and anus filled. I was hungering for males, for cock, for semen. Depraved thoughts increasingly pervaded my mind until I was completely consumed by them, barely to think of anything but sex and masturbation. My nipples were almost painfully erect, begging to be touched and reacting to the merest waft of air flowing across them. \n\nIt was estrus like mare was never meant to experience. It was maddening, and it required a sustained mental effort not to give in to lust or indeed the fear of what I was becoming. My heart went out to other ponies that had similarly suffered my appalling fate. No doubt a lesser mare would have crumbled and broken completely under such duress. I steeled myself, vowing to fight the Caribou’s designs until the very end.\n\nBut the intent to resist was the only thing I could manage in my hopeless position. To my great frustration the ropes tightly restrained me, barely allowing me to move a muscle. No matter what I tried, I was unable to break free or indeed find the relief that I so desperately craved. My powerlessness and utter lack of agency in this situation was vexing, and I could do little more than hope for rescue.\n\n————\n\nBy the time Dainn returned several days had passed. The longer I went without a load of sperm, the stronger the parasite’s hold over my desires became; after this period of abstinence my cravings had degenerated into a ravenous hunger for cock and cum. The moment I caught a waft of his scent I involuntarily let out a lustful moan.\n\n“Mhh! Hhhghh!!” my muffled voice sounded as I hoarsely inhaled the air, searching for the source of the musk.\n\n“Hmm, excellent. It looks like your transformation is progressing well, Cock Sleeve,” the Caribou spoke as he kneeled down to inspect my body. “Like your sister you are developing an exceptional physique. You two will be quite the sight to behold when you are fully trained slaves.”\n\nI could do little more than moan and shiver as he softly ran his hands along my curves, copping a good feel of my swollen rump. I hated that I let out a squeal in response. But by now I was so starved of touch that I instinctively pushed my cheeks into the bulls groping hands, lifting my tail and hoping for some form of sexual relief.\n\nI did not have to wait long. Dainn raised me up to my knees and removed my gag, pulling the phallic sex toy from my throat. I was met with the scent of his penis and testicles, bared just in front of my nose. My conscious mind planned to bite down hard on the vile slaver’s cock - I would have severed it completely if I could. But my parasite-addled instinct overruled the intent the moment my lips touched his tip. When his cock brushed against the skin of my lips, pure sexual pleasure coursed through my body. Instead of snapping my jaw went slack, welcoming the enormous flesh rod inside my throat.\n\n“MHHHHNNH!!” I moaned loudly when Dainn pushed his member deeply inside my mouth.\n\nMy mouth felt…like a vagina. It was raw pleasure, transmitted through my lips, tongue, even the palate and sides of my mouth. Dainn easily slid his enormous length down my throat, which to my surprise I was able to take it up to the hilt without gagging - another perverse effect of the parasitic infection. \n\nI could feel every bump and vein rub against my sensitized esophagus in all the right ways. The girth of his member stretched my throat to its limit, an unfamiliar feeling that very quickly became uniquely enjoyable. The sensation overpowered my last remaining thoughts of recalcitrance, giving way to the singular desire of having him fill me up as much as possible. The Caribou’s musk only added to my arousal; my nostrils flared as I greedily took in his intimate scent.\n\nGripping me by the sides of my head, Dainn started thrusting his cock in and out of my throat, raping me orally. I am embarrassed to admit that I was unable to put up any form of resistance. It provided me with an opportunity to release my pent up sexual frustration, and to this end I begrudgingly took part in the sordid act. The mutations induced by the parasite were transforming my oral cavity into a sex organ, and correspondingly the orgasms soon started flowing.\n\nI could not help but surrender to pleasure. Climax after climax wracked my body, leaving me moaning, trembling, squirting and squirming in Dainn’s hands. It was a satisfying reward for finally submitting to this depraved sexual experience, although I was loath to admit it.\n\n“Hrrgh…aah…good girl, Cock Sleeve,” the Caribou groaned lustfully. “Does it feel that good to have your mouth turned into a pussy?”\n\nIt was undeniable that it felt incredible. But it was equally worrisome that apparently my physical modification had not yet been fully realized. It was clear that besides utterly perverting and sexualizing my body, the slug would force me to experience extraordinary pleasure in ways that should not normally be possible. And I was soon to have a taste of what was in store for me.\n\nThe bull soon started moaning louder and louder - he was clearly enjoying the feeling of my tongue and throat wrapped around his cock. His balls slapped against my chin as he savagely started ramming his penis down my throat, his tip flaring in response to the building pleasure. Not that it felt uncomfortable - quite on the contrary.\n\n“Hnngh…I’m going to cum! Enjoy this, slave, and let the taste of your master be ingrained into your mind,” Dainn groaned, gripping my head tightly as he repeatedly hilted his shaft as deeply inside me as he could.\n\nI felt Dainn shudder as his penis throbbed, ejaculating his seed deeply down my throat. The ingestion of cum triggered a strong sucking and swallowing reflex within me, coupled with the intense need to deep throat his cock. Clearly the parasite was changing my behavior, taking control of my instincts to access the semen it required to survive. And as a reward, I experienced a series of otherworldly climaxes.\n\n“HMMMNN!! OOOHHNNHH!!” I screamed as I started cumming wildly.\n\nI felt my eyes roll into the back of my head, unable to think of anything but completely draining Dainn’s testicles as incredible waves of pleasure coursed through my body. The pulsations of his cock kept me orgasming over and over again, and the bull had copious amounts of sperm to feed me. The warlord moaned in ecstasy as he released the last of his load down my throat, but at the last moment of his orgasm he withdrew himself, spilling his semen onto my tongue in the process.

\n\nMy eyes widened in shock when I tasted his seed. The [i]flavor[/i] of it was incredibly strong. To my horror I realized the parasite had enhanced my tastebuds, greatly magnifying my sense of taste and texture.\n\nDainn’s sperm was utterly repulsive, and I would have spit it out right then and there. And yet, I did not. I could not. Instead of retching, I was slurping it up. I hated it. [i]But I needed it. I needed it more than anything.[/i]\n\nI could not help but use my tongue to explore every part of the bull’s shaft as its taste, smell and shape were etched into my soul. Even after he retracted himself I could not resist kissing and licking his penis, rubbing his cock and balls all over my face while I worshipped them.\n\n“Wonderful, it looks like the imprinting process has been a resounding success. You are a compatible host indeed, Cock Sleeve,” Dainn said with glee. “From now on, you will crave my cock and sperm as much as that of war beasts.”\n\n“No, no! ’Tis a lie!” I wailed in abject horror.\n\nBut deep down I knew a strong desire had taken root within me. I was barely able to break my lips free from his testicles, and every part of my body was screaming for more.\n\n“This craving will develop as our bond is strengthened, and will eventually become your sole motivation in life. Over time, it will turn you into one of my most loyal and obedient servants, existing only to serve my cock,” the Caribou spoke.\n\nBefore I could reject his assumption the savage reinserted my gag, pushing the sex toy down the back of my throat and locking it in place. \n\n“Your physical development has only begun, my pet. I look forward to seeing you once you’re fully fleshed out,” the bull spoke, leaving me fully restrained on the floor before locking the door behind him.\n\nIt would be days before he returned. Although the ingestion of Dainn’s seed momentarily allowed me to think clearly, I was still tightly bound. There was nothing I could do to escape. And as the hours passed the parasite started to hunger once more, and my ravenous sexual appetite returned accordingly. Soon I was unbearably aroused once again, driven to seek out the semen the slug required. \n\nDisconcertingly, the lustful thoughts implanted in my mind started focusing on Dainn specifically. As sexual fantasies started to pervade my thoughts, I could vividly recall his taste, shape and scent. Within half a day I was famished, and moaning with intense cravings and unfulfilled lust. Clearly, in order to remain somewhat in control of my faculties, I would have to ingest sperm orally or anally several times a day. It was both a humiliating and disgusting prospect.\n\nAnd all the while, my physical transformation continued. The slug completely assimilated into my body, fully turning my entire digestive tract into a sensitized sex organ. My rump reached its maximum fullness, now wide enough to able to take the war beasts’ monstrous cocks, and Dainn’s horrible ring now clasped my swollen clitoris tightly. My body was burning up, aching to be mounted and mated. I could do nothing but suffer through my ordeal, and hope for salvation that would never come.\n\n————\n\nWhen the door of my prison finally opened again, I instantly perceived Dainn’s scent. A mere waft of it triggered an instant, instinctive desire to seek the Caribou out. My nostrils flared as I ravenously inhaled his pheromones, all the while driven by the parasite to search out his cock. To my disgrace I could not help but moan like a depraved animal in heat, desperate for some relief from my lust. Sex hormones were raging throughout my body, leaving me so completely consumed by carnal desires that I could barely think of anything else.\n\n“Magnificent. You’ve become quite the sight to behold, Cock Sleeve. With a body like this, you will be the envy of Equestria,” the warlord said, eying me up before he untied my ropes.\n\nThe moment my limbs were freed I almost instinctively reached between my legs, looking to release my pent-up sexual frustration.\n\n“Mnnhhh!! Hnngh!!” I moaned into my gag.\n\nIt was shameful and unsightly, but I was not able to stop wildly fingering myself in front of the Caribou. What little coherent thought remained was unable to counteract the slug’s powerful directives. After just a couple of days of abstinence I had lost complete control of my body and its urges.\n\nMy clitoris was now enormously swollen, greatly enlarged in size and protruding from its clitoral hood. Although I found it a grotesque mutation, I could not deny that it provided me with greatly increased sexual pleasure. Like the rest of my body it had been enhanced, and was highly sensitive to the touch - despite my indignation at my physical corruption, I could not help but masturbate vigorously.\n\nIt should have been a quick release, but for the accursed spell engraved into my clitoral ring. Just when I was about to orgasm Dainn’s infernal rune magic activated. The icy chill of his power flowed through my loins and my very being, pulling me back from the brink and denying me my pleasure, keeping me highly aroused and frustrated.\n \n“Let this be a lesson, slave,” Dainn spoke sternly. “Know that I control your body, and that you are my possession. Only through my express permission will your pussy ever provide you with the pleasure you seek.”\n\nI could only grumble in response. The bull then removed my gag and to my surprise…kissed me. The touch of his lips against mine felt uniquely pleasurable. It was clear that the parasite had developed my lips and mouth even further, increasing the sensitivity to surpass that of my vagina. Any remaining thoughts of resistance melted away as the Caribou locked his lips with mine, pulling me in by placing his hand on the back of my head.\n\n“Hnnmh...mmh…” I moaned with delight as we kissed and our tongues intertwined.\n\nIt was unnatural, raw sexual pleasure. My tongue now felt as good, if not better than my modified clitoris. To my great shame I found myself leaning into my enslaver, reciprocating his advances. In my parasite-addled mind everything about him was arousing. The way he smelled, how he tasted. The way he kissed and tongued me, and wrapped his strong arms around me. The way he took control of me. \n\nDisgracefully, I found this innervating experience to be greatly enjoyable. It wasn’t long before I orgasmed, which left me breathless and squirting in the arms of the man who had personally collared me. As my trembling legs gave out underneath me, Dainn took a firm hold of my body, keeping our lips firmly locked together. I had no choice but to submit to pleasure. His kisses kept me cumming and cumming in his arms, until the brute finally released me.\n\n“Excellent, good girl. It’s rare for a host to develop such high oral sensitivity. You were truly born to become my anal slave, Cock Sleeve,” Dainn spoke with satisfaction.\n\nHis comment barely registered with me. I lay on the floor at his hooves as my body convulsed and spasmed in passion. I hated what the Caribou had done to me. I hated how they had succeeded in corrupting my body and perverting my mind. But I could not deny this had been one of the most pleasurable sexual experiences of my life.\n\nAs my senses slowly returned to me, the bull removed the hood from my head. After such a long time spent in total darkness it took a little while for my eyes to adjust to the light, but soon I could clearly see my enslaver standing in front of me. I only had an eye for one thing - his large, bared genitals.\n\nI flung myself at him like a famished beast, unable to control my urges. Lust overrode any remaining notions of modesty, and I shamelessly started kissing and licking the Caribou’s balls. It was feral, animalistic physical attraction. Any mental objections to this immoral sex act were overpowered by the parasite’s directive to its host - to seek out sperm. And seeing me in my state of heat, under complete control of the slug clearly aroused the warlord. His shaft soon started stiffening, extending from its sheath and rapidly reaching full erectness. I was instantly drawn to it, rushing to envelop Dainn’s veiny cock with my now fully sensitized lips. \n\nIt felt even better than the last time the Caribou raped me orally. I plunged his penis as deeply down my throat as I could, sucking the bull off in a wild, unbridled fashion. \n\n“Haargh!! Marvelous, slave!” the savage grunted with ecstasy as I worked his massive member.\n\nWith my gag reflex completely suppressed, I easily made my way up and down the full length of his penis, from his tip all the way down to the base of his sheath. Every bump and ridge rubbed me in all the right places, and gratuitous pleasure flowed from my lips, tongue and mouth. And the bull similarly enjoyed himself. His flaring of his cock stretched out my throat, sending even greater pleasure coursing though my body. I could not help but moan like a harlot, knowing that my prize was about to pour into my stomach. \n\nBut suddenly, the bull grabbed me by my mane and pulled his member out of my mouth. Perplexed, I lunged for his cock, seeking to sate my ravenous hunger for sperm. But Dainn’s grip was firm, and he forced me face down onto the floor of the prison, raising my rump up into the air.\n\nI did not resist him, nor would I have been capable of doing so. Instead I squealed like a common harlot when I felt his tip push against my sphincter. With a smooth thrust of his hips, the Caribou effortlessly slid his penis inside my body.\n\nIt felt like the first time I was anally penetrated. I felt momentary discomfort as his enormous girth stretched and split me apart - but the pain was soon replaced by otherworldly pleasure. The lubrication of my innards meant that Dainn was able to probe my depths unopposed, and the brute inserted himself fully. \n\n“Hrrggh! Your asshole is gripping my cock like a vice!” Dainn grunted lustfully as he pushed his shaft up my backside. “It’s incredible how much you’ve tightened up!”\n\nBeing filled up and stretched like that activated something primal in my brain, a feeling of intense satisfaction, fulfillment and bliss. By now my anal cavity had been fully developed by the parasite, allowing me to feel every movement of the warlord’s penis deeply inside my bowels. It felt better than the best vaginal sex I had ever experienced, overwhelming my senses no matter how much I tried to refuse it. Although I was aware of the parasite’s influence on my mind, I could do little more than moan as Dainn started ploughing me roughly. The slug was in complete control of my urges, and I could do nothing but comply.\n\nThe Caribou equally lost himself in ecstasy, copping a good feel of my swollen rump and slapping my butt cheeks roughly as he pounded my backside. I could feel his cock flaring once more - he was about to cum.\n\n“Beg for it, whore,” Dainn whispered into my ear. “Beg your master to cum inside your asshole.”\n\nHad I been in full control of my faculties, I would have refused to comply with such a demand. But I was consumed with an all encompassing craving for his seed, and in my state of hunger I could no longer help myself.\n\n“Hngh…ahh…p-please master…cum inside my ooh…asshole…” I muttered.\n\n“Again, Cock Sleeve! Speak clearly when addressing your master!” the bull demanded sternly.\n\n“Please Master Dainn, cum inside Cock Sleeve’s asshole!” I cried, much to the Caribou’s satisfaction.\n\n“Good girl,” his praise sounded. “Now, enjoy the cum you so desire.”\n\nWithin a few hard thrusts, I felt Dainn’s cock throbbing, injecting his filth deeply inside my bowels. The orgasms started flowing as soon as he ejaculated, a powerful physical reaction to the Caribou’s semen induced by the parasitic infection. What little free will remained within me detested being made to orgasm in such a depraved manner, but I was powerless to stop myself from climaxing. The bull’s fingers dug into me as he gripped my hips, hilting himself continuously while he fed me the sperm I needed. I was forced to cum over and over again, moaning like a whore while being raped by my enslaver. \n\nIt was in this utterly sordid and perverse union of bodies that I was filled with an intense feeling of complete satisfaction, joy and sexual bliss, unlike anything I had ever experienced before. Vexingly, the slug was manipulating my mind, seeking to reinforce my behavior. I was too exhausted to fight it however, and when the bull retracted his cock from my fundament I collapsed onto the floor, losing consciousness.\n\n————\n\nDainn returned to violate me repeatedly over the following weeks, purposefully leaving several days between visits to ensure the parasite was starved and I was fully receptive. \n\nTo my frustration this simple method of imprinting was extremely effective. Against my will, my physical attraction to the Caribou became stronger with each session, and my hunger for his seed ever more voracious. Although mentally I resisted fiercely, I quickly developed a strong physical reaction to his presence. I became highly sensitive to his scent and pheromones and was unable to stop the strong sexual arousal I developed in response. Despite its repulsive taste, I grew completely addicted to Dainn’s cum, such that my depraved lust for it never truly abated even after hours of sex. \n\nOver time, the parasite’s will seemed to blend with mine, making it difficult to distinguish which thoughts and impulses were truly my own. Now fully established and gaining in strength, the slug was in full control of my sexual instincts and desires, and was slowly warping me into a sperm-crazed nymphomaniac. Perverse thoughts pervaded even my dreams, implanting sexual fantasies into my mind as my body desperately sought the release it so desperately needed.\n\nAs the hateful bond between master and slave strengthened, so did I begrudgingly learn to enjoy my developing body. The sheer pleasure that oral sex provided me made me think how I had managed to live without it for so long, and the incredible orgasms I experienced when Dainn ejaculated inside me were truly heavenly. No matter how long the fiend raped me with his massive cock, by the next time he returned my rectum seemed to have tightened back up completely, allowing me to experience the full stretching of my anus time and time again. \n\nMentally I was acutely aware of how immoral and repulsive my thoughts were, but in my ravenous state I was entirely unable to suppress my carnal desires. The Caribou lord took full advantage of me, using my extreme arousal to make me beg for his cock. To my disgrace I could not resist submitting to his will, sucking and riding his cock while cumming wildly like a sex-crazed beast.\n\n————\n\nWhen Dainn finally led me out of that horrible room I was a changed mare. I had to fight back the tears when I saw my reflection in a mirror. My sleek elegant shape had been ruined, corrupted into a voluptuous, sexualized figure. The parasite was now an inseparable part of my body; I had become little more than a repulsive sex organ. Hormones are raging through my body, imbuing me with seemingly endless lust. Maintaining my self control is a continuous, laborious task, and despite my best efforts it is clear that it is impossible hold my instincts at bay forever. \n\nAs such, I cannot see how a return to a normal, respectable life will be possible. The quantities of semen I require to satisfy my hunger are considerable, meaning I would have to spend most of the day feeding - a habit I will need to follow for life. And even when satiated, my lucidity only lasts a couple of hours before I am once again overcome by arousal, to the point that sex consumes my every thought and desire. Even as I write this I struggle to concentrate, and my hands have strayed many a time.\n\nI must admit to feelings of despair, but I must not bemoan my doom. I must remain strong for my ponies, regardless of what will become of me. Others may be subjected to worse fates, difficult though it may be to imagine. My suffering matters little in the grand scheme of things. As long as we can make it through, surely we will be able to rebuild our society despite the Caribou’s efforts to pervert and corrupt us all.\n\nI will never submit to the Caribou as long as I draw breath. Whatever these vile barbarians’ plans for me are, I shall repudiate and reject them utterly. It is my duty as a princess of Equestria.\n\n- [i]Princess Luna[/i]", "writing_bbcode_parsed": "Locked in complete darkness, I was left to mull over my fate. In my current state there was nothing I could do to free myself - the Caribou were thorough in their work and their devices too solidly built for me to break free on my own. And even if I managed to escape they were still in complete control of the castle, with the treasonous Royal Guard patrolling the hallways and keeping a close watch on every gate. I was left to stew in my thoughts, in my fury, frustration, humiliation, anger and helplessness. But equally and increasingly my thoughts turned to concern for our citizens and those dear to me, such as my sister. I cannot imagine what horrors they must be going through.

The plug inserted into my anus was evidently inscribed with the same arousal spell as before, and I was soon gripped by desire once more. I cursed the potency of the Caribou’s magic. It forced me into an overpowering state of heat, and I found myself unbearably aroused. I started sweating, and my winking sanctity leaked with shame. As a result sexual thoughts began pervading my mind, which resurfaced no matter how hard I tried to suppress them.

I could only grumble in frustration, unable to relieve my pent up lust in my predicament. Yet I resolved to refuse my carnal desires, knowing that succumbing to temptation would bring me ever closer to defeat.

The first day of torment was nightmarish. My belly was churning and cramping, the horrific torture made worse by the tight confines of my unyielding restraints. I never quite got used to the liquid filling my intestines, which I could feel sloshing around inside me whenever I attempted to break my restraints. It was an unpleasant sensation to say the least. To my relief the painful cramping subsided somewhat as time went on, although the need to empty myself was ever present.

To my surprise I experienced neither thirst nor hunger during this time. Whatever fluid was inserted into my digestive tract must have been supplemented with sufficient nutrients to sustain me over an extended period. But little did I know my experience of Tartarus had only just begun.

————

The next morning I was awoken by the turning of the heavy iron key that unlocked the door to my prison. It was Anvari, who had returned bearing most unpleasant news.

“I trust you had a pleasant night, princess,” he spoke mockingly while inspecting the shackles and leather straps that kept me restrained. “King Dainn has ordered for you to be made into his anal slave. He has recognized your unique physical qualities and has commanded you undergo extensive anal training, so your ass will be put to proper use. As such you will be subjected to the necessary physical enhancements in order to optimally perform your new tasks in life.

“No cock will penetrate your cunt ever again, no matter how much you beg and crave for it - save for at your master’s mercy and grace. As a sign of your new station in life your pussy will be sealed, communicating to all that you are an anal slave and inviting them to fuck your asshole.”

The bull opened a small wooden box he had brought with him, which contained a set of piercing needles and rings.

“These rings are infused with a magical seal, which can only be broken by your owner’s specific order. Only at his command can they ever be removed,” Anvari continued. “Understand that he holds your fate in his hands. He has complete control over your body and mind, and you are beholden to his will.”

To my horror, the fiend intended to physically seal my vagina.

“NHHH!! MMGHH!!” I screamed in panic, thrashing wildly against my restraints.

I fought with all my might to break free, struggling against the leather straps that kept my limbs spread wide. Even my wing sheaths stretched and creaked as I fought desperately to prevent the sadist from enacting his appalling plan. But no matter how hard I struggled the bonds would not break.

The bull poured some liquid from a bottle onto his hands and lathered my crotch with it. It caused a slight tingling sensation, which quickly ebbed away.

“This is both a disinfectant and numbing agent, which will prevent infection and reduce the pain. Regardless, any discomfort will be only momentary,” the Caribou spoke while he reached for his tools.

Thankfully the anesthetic worked quickly, such that I could only faintly feel him pinching and tugging at my labia with his fingers. The fact that I was still fully hooded only made the experience worse. I screamed when the needle pierced my skin. Although the pain was only faint, the thought of being disfigured and taken control of in such a manner was unbearable.

“HRRRRGHHH!!” I wailed, as I felt the bull remove the needle from my skin, before realigning it slightly further down.

The savage worked quickly, immediately pushing the sharp implement through both of my lips once more. It was over before I knew it.

“Stop complaining. It’s only a minor procedure,” Anvari grumbled, while disinfecting and treating the puncture wounds with a viscous salve. “This will speed up the healing process. You’ll be completely pain-free in no time.”

The fiend then took the two silver rings and carefully threaded them through both of my labia, locking my lips together. As soon as Anvari put the second piercing in place I felt Dainn’s accursed runic enchantment taking hold, cold as the winter’s chill.

“NNHHH!!” I screamed while desperately trying to shake the jewelry off somehow.

“Your cunt looks beautiful like this, slave. These rings will prevent cocks from penetrating your pussy. The gap is large enough for fingers to enter however, in case your master chooses to reward you in such a way,” the bull said as he calmly disinfected his tools before storing them away.

It was an unbearable insult. Like my collar and wing sheaths it was yet another reminder that I was considered to be little more than property. I was apoplectic with rage, screaming and shouting into my gag while fighting and struggling against the chains and shackles that imprisoned me. I would have eviscerated the Caribou on the spot if I still could.

“In addition, King Dainn has generously bestowed you with a new name more befitting of something of your status. From now on you will be known as Cock Sleeve, and references to your former name have been formally erased from the records,” the brute continued, his voice betraying a hint of glee. “Be grateful for his generosity, for such an honor is only bestowed upon a select few. I gather the populace has reacted with unanimous approval upon being read his royal decree.”

The disgusting name was grievously insulting, and left me incandescent with fury. Not only would I be made to serve my enslaver in an utterly repulsive manner, my horribly degrading slave name also affirmed my place as one of his sex toys - a humiliating notion I could never accept.

“Most household or cattle slaves are little more than objects that may be replaced at their owner’s whim. As such, names are often not bothered with. Bestowing a slave with a name is therefore a sign of a master’s favor, and a gesture of great generosity,” Anvari said, now turning his attention back towards me. “It shows he considers you of sufficient quality to spend the time and resources necessary to raise you as a proper sex slave.

“Although officially all cunts share the same status as property, exceptional slaves are often selected to made into center pieces in their master’s harem. They become symbols of his status, performing roles in public that show off their exceptional qualities. Please your owner according to his demands, and you may lead a life of pleasure and comfort in his service. Resist, and it will be made as miserable as that of the lowest black collar slave.

“Now then Cock Sleeve, tell me your name and purpose,” the villain spoke, before pulling the penis gag from my throat.

I coughed and retched for a moment, before taking a deep breath.

“I am Princess Luna of Equestria!” I declared defiantly. “I shall never submit to the likes of you!”

The Caribou immediately forced the phallus back down my throat in response.

“Hmm, just as I expected. That does make this exercise, shall we say…a bit more entertaining,” Anvari spoke, with a hint of deviousness in his voice. “Until you answer me correctly, you will not find relief. As a matter of fact, your discomfort will only increase.

“Your anal plug has a special valve, allowing the injection of additional liquid without first requiring its removal. Understand that you will only know relief from your situation at my discretion, and that you are experiencing but a small measure of discomfort. Obey, and you will be kept in relative comfort. But should you choose noncompliance, each day the amount of laxative added to your enema will increase, and so will the pain you experience.”

The bull took the clyster syringe’s catheter, connecting it to the valve on my butt plug. I shrieked when I felt the second load of fluid being forced into my bowels, distending my stomach even further. The intense cramps instantly returned as the liquid sloshed around my innards, filling me up more and more as the latex fabric of my suit stretched around my belly.

“NHHHGHHH!!” I screamed into my gag, unable to bear the heinous indignity.

“Exactly how uncomfortable things get is entirely up to you. This is a very simple lesson, cunt. You already know what the correct answer is. I will return tomorrow to see if your attitude has improved,” the vile sadist spoke calmly.

With that he locked the door behind him. I was left in complete silence and darkness once again, except now my intestinal discomfort had doubled. The cramps were more intense and painful than before, taking longer to abate, not to mention the greater distention of my stomach. I could do little more than suffer through the ordeal, although it was a price I was happy to pay.

————

Anvari was true to his word, only returning the next morning to repeat his insulting question. Again I resolutely rebuked him, and again he injected another syringe worth of fluid into my rectum, further increasing my pain and suffering.

The bull was both consistent and patient - each day the ritual was played out in exactly the same manner. No matter in what way I repudiated him, he methodically meted out my punishment, greatly increasing my discomfort every time I defied him.

This routine continued for several days, until by the fifth morning the experience had become excruciating. The horrible cramps were constant and my stomach was hugely swollen by the sheer volume of liquid trapped inside me. By now I was sweating profusely, writhing in agony and overcome with an overpowering need to empty myself. But no matter how much I tried, the accursed plug kept me tightly sealed, preventing any form of relief. Panicked attempts to free myself only resulted in triggering horrible spasms, and achieved nothing but increasing my suffering.

In addition, my magically-induced state of heat had become unbearable. I was drenched with arousal, leaking fluids and winking uncontrollably. Every movement of my labia pulled against those infernal rings Anvari had pierced me with, a continuous reminder of my disfigurement.

When the torturer returned he slowly removed my cock gag, seemingly taking delight in my humiliation and suffering.

“I will ask you again, cunt. What is your name, and what is your purpose in life?” Anvari asked, running his hand over my distended stomach.

“…Hngh…ah…I-I…” I mumbled.

I was loath to suffer more punishment, but I could not bring myself to call myself by such a despicable and humiliating name. Much to my dismay, my momentary silence was enough for the bull to shove the phallus straight back down my throat.

“You will answer immediately and clearly when a male addresses you, slave,” the barbarian spoke sternly. “You would do well to remember this.”

“MHHHH!! HHRRRGH!!” I wailed, straining myself against the following influx of fluid.

It hurt. The laxative induced horrible, severe cramping in my stomach. My insides were now greatly stretched and distended, and I was absolutely desperate for some relief. The bull was merciless however, injecting the full load of the syringe inside my body and leaving me locked inside my prison once again.

I was now so full that the pain and discomfort did not abate, even after several hours. My innards felt stretched to their absolute limits, to the point that I was certain I would not be able to take another syringe full of fluid. I looked like I was heavily pregnant, to the point that my enormously swollen stomach was splitting the fabric of my rubber suit.

It was pure suffering. Any sort of movement would send the liquid sloshing inside my bowels, triggering the most horrible intestinal cramps. My absolute state of helplessness was vexing, and the realization that there was no way out insufferable. All this time there had been no indication that help was forthcoming, nor had there been any sign of rescue. My fate was entirely in my torturer’s hands.

By the time Anvari returned, I was begging for it to be over. I couldn’t take another enema, another day in this Tartarus. No matter how degrading it would be, I had to face the fact that this was a battle that I could not win. For my own wellbeing I needed to relieve myself, urgently.

“Cock Sleeve, my name is Cock Sleeve!” I exclaimed the moment he pulled the gag from my mouth.

“Good girl. Now that wasn’t so hard, wasn’t it?” Anvari spoke with satisfaction. “Now tell me, what are you, and who is your owner? And I remind you to use the proper appellations.”

“I…am…ngh…Master Dainn’s…anal slave…”

“Again, cunt,” the Caribou lord demanded sternly. “State your name and purpose, clearly and promptly, unless you want me to give you another enema.”

“My name is Cock Sleeve, I am Master Dainn’s personal anal slave!” I cried, fearful of yet another day of torture.

“Good girl,” the bull spoke, running his hand from my swollen belly down to my crotch. “Never forget - recalcitrant slaves are punished without mercy. But obedient girls receive pleasure for their submission.”

His fingers felt heavenly on my touch-starved vagina. By now I was in an unbearable state of heat, and at no point had I been able to satisfy my pent-up desire. I was unable to resist him, neither physically nor mentally. The bull expertly teased my folds, running his fingers along my labia and attending to my clitoris. His experience showed; he effortlessly found just the right rhythm and pressure to make me squeal.

“HHNNGGH!!” I moaned loudly into my gag.

To my frustration it was an expression of pure, unadulterated pleasure. I hated my failure to suppress my carnal desires. But each time I managed to wrest back some semblance of control, the Caribou’s fingers instantly made me lose it again.

The orgasms came quickly, and in rapid succession. I cursed Anvari’s ability with his hands. He made me scream like a common harlot when he gently inserted his finger into the gap above my piercings, pleasuring my g-spot like I have never experienced before. With a flick of his finger he was able to drive me to incredible heights of sexual bliss, making me squeal, cum, squirt and convulse over and over again. If it weren’t for the enormous plug lodged inside my rump, I’m sure I would have expelled the fluid right then and there.

Anvari let me ride out my orgasm, enjoying the sight of my trembling body, swollen stomach and heaving chest as I caught my breath.

“Please…ooh…a-allow me to relieve myself,” I asked softly, still panting heavily.

“I remind you that you’re talking to a male, cunt,” the Caribou lord answered sternly. “You will address me with respect at all times. Use the proper appellations, unless you want to stay in here for another week.”

“Ngh…please M-master Anvari, allow this…anal slave to relieve herself,” I begged.

Humiliating as it was, I could only give the bull what he wanted. My body was screaming for release from the discomfort and pain, and I was not sure if I would be able to physically take another enema, not to mention another hellish day locked in complete isolation.

“Hmm, good girl. Despite your attitude I can tell you’re a quick learner. In time you’ll no doubt become one of the most desirable sex slaves in Equestria,” Anvari said, placing a large container underneath my rump. “Now, the men have enjoyed watching you struggle over the past week. Make sure to give them a good show.”

Unbeknownst to me, the Caribou had been recording me the entire time. The images had been broadcast to the populace with the intent of stripping me of all dignity and grace, ruining and twisting my public image into that of a subjugated slave. It hurt me grievously, but I could only fight back the tears as I felt Anvari reach for my anal plug.

The floodgates opened the moment he pulled the sex toy free from my sphincter.

“Aaaghhh!! Hnnnghh!!” I screamed, as a week’s worth of enemas finally burst out of my body, splattering into the container below me.

Undignified and disgusting as it was, it was a relief to finally have the pressure inside my stomach released. Gradually the flow slowed down to a trickle, and I was left panting on the table while I was unceremoniously hosed down with water.

“This is just the beginning of your life as an anal slave, Cock Sleeve. But before you start your training, you’ll first need to be physically prepared in order to unleash your full potential,” Anvari spoke as I slowly recovered from my ordeal.

I did not understand what he meant, and in hindsight I was glad I didn’t. At the Caribou’s call my handlers entered the room, unlocking my shackles and taking me down from the table. In my exhausted state I struggled to stand and collapsed onto my knees, only being held up by the strong grip of the two bulls.

“Clean her up properly and take her to Lord Hrathr. He should have completed the necessary preparations and will be expecting her,” the Caribou lord spoke while he washed his hands.

“As you command, Lord Anvari,” the men responded, before taking me out of the holding cell to be bathed.

After a week spent sealed inside the rubber suit, I stank. Being too physically spent to offer any significant resistance, I was stripped down, washed and shaven. I was loath to perceive it as reward for my compliance, but the bath was a genuine relief and a brief moment of enjoyment after a week of pure torture.

I realized this was exactly Anvari’s intent, and an example of how insidious the slave training techniques of the Caribou can be. By strictly controlling punishment and reward, even seemingly innocuous moments of comfort are used to manipulate their victims, subconsciously molding them into their submissive servants.

But despite this knowledge, and as invasive as being washed by somepony else’s hands is, I could not help but enjoy the smell of soap, the shampoo in my mane and tail, and the feeling of warm water washing the filth off my skin. It was not to last however. After I was made presentable and had recovered some of my strength, I was lifted back onto my hooves, shackled and marched to a different section of the castle.

————

The recreation hall was an annex of the palace, where guests used to be entertained and where celebrations were held. The Caribou evidently had other ways of passing their free time, and were in the process of converting the hall into what seemed like laboratories of sorts. New rooms were being constructed, with rows of strange equipment and devices placed throughout.

I was not prepared for the horrific abuse I was about to witness there.

Girls from all walks of life were incarcerated in the labs - from Wonderbolts to guardsmares to ponies who had come from the countryside to try their luck in the capital. Every single one of them had been collared, and had any horns removed and wings sheathed. Some had symbols tattooed onto their skin or had even been branded, presumably to humiliatingly mark them as slaves, indicate ownership or otherwise marking them as property.

Not only had they captured mares, but also the females of the other inhabitants of Equestria such as griffins, buffaloes and even dragons. All were treated equally - as living sex toys, to be used for the enjoyment of the realm’s new ruling class.

As is the invaders’ wont, all of the captives were completely restrained. Some with shackles and chains, others with intricate rope work or even locked into the machinery. Regardless of the method employed, all of the girls were forced into postures that preserved none of their dignity. Their clothes, if they wore anything at all, were scant in most cases, clearly designed to emphasize their sexual features. The designs made gratuitous use of leather and rubber, and were often mere strips connected by metal rings. Rather than preserving a girl’s modesty, they kept her shame completely exposed, drawing the onlooker’s eye towards her bare crotch, breasts, rump and legs.

Many were being violated in some way or another - some by vibrators held against their private parts, while others were being penetrated by phallic toys mechanically driven by pistons. Other unfortunate captives had suction devices attached to their vaginas which drew out their bodily fluids whenever they climaxed. These were then force-fed to the hapless victims by being sucked up through a tube connected to their mouths.

I saw one Caribou inject a poor mare’s breasts with a serum of sorts. For a moment the girl struggled before her chest swelled up both in size and fullness, growing out several cups. While she was staring in disbelief at her enormously expanded globes, the bull connected two suction cups to her nipples. Milk started flowing instantly, filling up the tubes and pouring into a large holding tank behind her.

There seemed to be no end to the unspeakably depraved sexual contraptions the Caribou had devised. I observed strange machines driving what looked like large spheres into an enslaved dragon’s rump, causing her to cum and squirt wildly. Inside another cell a luckless buffalo cow had been heavily restrained, and seemed to have electrodes attached to her breasts and crotch. Other mares were being pumped full with substances flowing from holding tanks and intravenous drips.

What seemed to be happening in these laboratories were horrific, immoral experiments, aimed at manipulating the minds of slaves as well as enhancing and augmenting their bodies, so they could better serve their purpose as sex objects. Some were aimed at modifying a captive’s physique, creating an idealized, sexualized figure to sate her master’s perverted fantasies. Yet others featured machinery connected to their hapless victims’ heads, suggesting they were undergoing some sort of mental manipulation. Presumably this was a form of brainwashing, enabling the Caribou to better control their subjects.

Treatment such as this is abhorrent, barbaric and uncivilized, not to mention a gross violation of a mare’s right to control her own body. But it is nothing out of the ordinary for creatures as vile and despicable as the Caribou, and just one of many terrible examples of sexual abuse that I would witness that day. My heart went out to these unfortunate victims, and I deeply regretted by inability to intervene and put a stop to the proceedings. But chained as I was I could do little to alleviate their suffering. A quick stab of the cattle prod and a tug on my leash reminded me to keep following my handlers down the hallway.

Eventually we came to a confluence in the path, where we were met by another Caribou lord. Hrathr was his name, and he was a large, muscular brute of a bull. He was an imposing figure, taller and broader of frame than Anvari, but going by his balding head and the wrinkles in his face he was well into middle age. Despite his years he was a beast master by trade, and it showed - his arms and face bore numerous scars, and one of his antlers had been partially broken off.

“Greetings Lord Hrathr,” one of my handlers spoke after saluting the elder bull. “Lord Anvari sends you this slave, as was commanded by King Dainn.”

“So this is the younger sister,” Hrathr spoke, eying me up as if I were a piece of meat. “A mare of fine quality indeed. We’ll make a proper sex slave out of you yet.”

“Do your worst, slaver. But do not think a princess of Equestria will fall so easily to the likes of you,” I spat at the savage in disdain.

“Hmm, I was told of your recalcitrant character. But despite your upbringing you’ll soon find that you’re a cunt like any other,” Hrathr answered bemusedly. “Come and see for yourself.”

The beast master rudely yanked me by my leash, dragging me to a nearby room. When I peered through the window I stood frozen in shock.

Behind the glass pane of the isolated cell I could see my sister, buck naked and trapped on all fours in a contraption that completely immobilized her arms and legs. Her head was covered by a helmet and her eyes by a visor; a mask sealed her muzzle and fully enclosed her visage in rubber. But I could tell from the colors of her mane and tail that it was unmistakably Celestia.

She had been dehorned as I was. The thick black collar of a Caribou slave was clasped around her neck, complemented by the same torturous black wing sheaths that I had been forced to wear. To my horror, her cutie mark had been defaced by a brand resembling a pair of chains overlaid on her Sun, a permanent, physical reminder of her captivity. A fiendish sex device was desecrating her from behind, mercilessly thrusting a pair of large dildos in and out of both of her holes. She looked completely disheveled, and her body was covered in sweat. My sister had evidently been locked inside this torture chamber for days on end.

“Tia! Tia!” I exclaimed in dismay. “What are they doing to you?!”

I banged on the window separating us but the material dulled the sound, and the device locked around her head prevented my voice from reaching her ears.

“You waste your time, cunt. We control all of her senses completely - what she sees, hears, smells, tastes, feels and even when she cums,” Hrathr spoke. “She is the king’s private property now, and is being prepared for her new life as his sex slave.”

From the multitude of screens mounted on the walls around Celestia I gathered that she was being subjected to a thorough mental conditioning regime. The Caribou were keeping a close eye on her vital signs, monitoring and manipulating her hormone levels and mental state. Through her visor the fiends were projecting perverse imagery onto her eyes; many wires were connected directly to her helmet, stimulating her brain in order to twist and corrupt her in insidious ways. Part of the helmet’s design covered Celestia’s ears, and additional wires connecting to the machinery beside her seemed to indicate that she was being indoctrinated around the clock.

Several cameras recorded the process from various obscene angles, preserving none of my sister’s dignity. Behind her I saw a large holding tank containing a disgusting, viscous fluid. From what I could make out from a label stuck to the glass, it was the sperm of war beasts. The container was connected to her mask by a large tube, which was joined by smaller tubes connected directly to her nostrils, controlling her intake of air and scent.

I cursed my powerlessness as I beheld the horrifying scene. Disconcertingly, a pool of liquid between Celestia’s legs showed that perhaps she had enjoyed herself a little too much.

“King Dainn has special plans for this bitch. Like you she is an exceptional beauty, and possesses prodigious talent,” Hrathr said, observing the proceedings with satisfaction. “Although she resists, she lacks your stubborn predisposition. Through guidance from a firm hand and the right teachings she will become an extraordinary sex slave.

“As a fresh cunt she has much to unlearn, but she is proving herself to be quite receptive to our teachings. She will be trained to the very highest standards - nothing but perfection will be expected from the king’s fuck pet. Sun Slut is her name now, although I hear some guards enjoy informally using the nickname Cuntlestia, in mockery of who she once was.”

“Her name is Celestia, and she will never break! She is a princess of Equestria and will never submit to the likes of you!” I spat at the beast master, disgusted at the preposterous notion that my sister would ever willingly kneel before him.

“Hmph, you think too much of your whore of a sister. Pleasure is both a powerful teacher and master, and it’s obvious that she enjoys her treatment,” Hrathr retorted. “Observe closely, as she is reduced to little more than a whore.”

As I was forced to watch Celestia being violated, I could see her…starting to grind her hips backwards, receiving the twin sex toys with vigor. As far as I could tell, she was moving out of her own volition, harder and faster with each thrust. She arched her back, throwing her head back in passion…was she…truly enjoying this somehow? Then suddenly I could see her body tensing up, before starting to shake and tremble violently. The cameras captured the jets of liquid squirting from her crotch, splattering on the floor behind her.

My sister was orgasming wildly.

In the midst of her climax, the semen inside the tank was pumped through the feeding tube connected to her mask. Celestia struggled and strained as the revolting liquid poured into her mouth. The Caribou were force-feeding her war beast sperm right at the moment of orgasm, manipulating her mind into associating its taste and scent with pleasure. For a moment my sister seemed to resist the flow, attempting to dislodge her feeding tube by shaking her head. The device did not allow for any overflow however, and I soon saw her throat distend as the liquid was forced down into her stomach. The flow was relentless, and she soon accepted her feed, actively gulping down her reward.

And through it all, I could tell that she was cumming and cumming.

“Little by little, every orgasm rewires her brain and ingrains her lessons deeper and deeper, gradually molding her into a maximally submissive whore. Much of her resistance comes from unfounded notions of dignity, modesty, customs and manners. But deep down she has all the makings of a depraved slut,” Hrathr spoke. “In time we will be turn her into one of the finest sex slaves in Equestria, famed for her physique, obedience and sexual prowess.”

“No! Celestia! Fight it sister!” I screamed desperately, banging on the glass.

But she was in the throes of lust, and the infernal device covering her visage prevented her from hearing me.

“Down, cunt!” Hrathr shouted as he yanked me away from the windowpane with a powerful tug of my leash. “It’s time to prepare you for your new station in life.”

I screamed and kicked as the brute dragged me away down the hallway. Catching one last glimpse of my sister, I couldn’t help but anguish over the horrible fate that had befallen her. Her body was now slumped over, still shuddering as she rode out her climax. I could tell she was exhausted, but the machine was unrelenting. The cycle restarted and I could see the pistons starting to move again, picking up the pace as they plunged in and out of her sanctity. Suddenly Celestia contorted her tortured body, as if she struggled against a sudden impulse of sorts - but what was happening to her I could not tell.

————

Hrathr forcibly marched me to another room on the far side of the hallway, easily overpowering my attempts to fight him off. Despite my struggling he shackled me eagle spread to two vertical wooden bars set about a leg’s width apart.

“Release me you wretch!” I screamed at him, intent on showing the savage he would not find me easy prey.

The beast master ignored me, taking a large glass cylinder off a shelf on the wall. It contained what looked like a green amorphous blob, slowly moving around a transparent but viscous liquid.

“This slug is a parasite that requires semen for its survival and reproductive needs. It normally infests female war beasts, but in the absence of one any female may serve as its host. Normally it will seek to penetrate the vagina, but alternatively the anus will serve just as well as a point of entry,” Hrathr spoke as he twisted the cap of the container. “Once the slug nestles inside you it will gradually fuse with your body, effectively becoming a reproductive organ that drives you to relentlessly seek out cum. It excretes powerful sex hormones which will modify your physique and behavior, turning you into little more than a sperm receptacle with a strong affinity for war beast cock.

“If nothing else, it’s a suitable fate for a slave of your name, Cock Sleeve.”

Hrathr twisted the cap, opening the container to set the creature loose. It was a large, disgusting, elongated slithering thing, covered in many small ribs, nubs and tentacles. A slimy ooze continually seeped out of its pores as it moved, filling me with revulsion.

Within moments the gelatinous blob seemed to sense my presence, guided by its feelers detecting my scent. The Caribou lord then approached me with the jar, allowing the slug to climb onto my leg.

Fear and panic set in the moment I felt the parasite’s cold body latch on, its slimy foot firmly gripping my skin. I thrashed about wildly, screaming as I tried to shake the creature off of me. But it stuck tightly to my body, and my movements only seemed to stimulate it to seek out my orifices.

“No! No stop! You cannot do this to me!” I cried, but my pleas fell on deaf ears.

Disregarding my screams and struggles, Hrathr turned on a large monitor on the wall in front of me. To add insult to injury the sadistic brute had placed a camera on the floor behind me, which was zoomed in on my rump. He was going to make me watch the ordeal from up close.

Gripped by terror, I could only watch while the slug slowly but unrelentingly slithered up my leg. My body was shaking, and breaking out in cold sweat. I whimpered as the creature probed my sealed vagina. It was cold and slimy to the touch, and altogether most disagreeable. But the gap left by my piercings was too small for the parasite to fit through, and it quickly turned its attention towards my anus.

I shrieked as the creature now started probing my rectum, sending out its tentacles to search for a way into my body. I clenched as hard as I could, desperate to keep the slug out at all costs. But it was covered in mucus, and after a few exploratory touches to find its point of entry, forcibly slid into my rump.

It was a horrifying feeling. The parasite was cold and slippery, and despite my best efforts it wriggled itself inside my anal cavity with a few pulsating contractions.

“NO! NOOO!!” I screamed as the parasite slowly slithered up my bowels.

“That’s it, fight it as much as you can, cunt. It’s pointless,” the sadistic fiend spoke. “These parasites have evolved to overcome a struggling host. The more you resist, the more it will excrete a muscle relaxant in its mucus, facilitating its entry into your body.”

To my horror, the Caribou was right. Each time I pushed the disgusting creature out of my body, it repeated its attacks with renewed vigor. Each time it felt slimier, only adding to the lubrication of my anal passage and making it ever harder to stop it from penetrating me. On the screen I could see I was starting to fail to expel the slug entirely, as my weakening sphincter no longer had the strength to push it out completely before it resumed its attempts to invade me.

The creature was now sliding deeper and deeper inside me with every attack. I was soon panting heavily from the strain, fueled by fear, adrenaline, and an absolute refusal to be desecrated in this manner. But the parasite was equally unrelenting in its pursuit of claiming me as its host, and it soon exhausted me enough to keep most of its body inside me no matter how hard I tried to push it out. Despite my spirited resistance the revolting thing was gradually and inexorably winning the battle.

Seemingly noticing it was close to overcoming my resistance, the slug’s pulsating movements suddenly increased in intensity and vigor. Taking me by surprise, it succeeded in wholly slipping itself inside my anus. It was horrifying to see the entire thing disappearing up my rump. I once again tried to expel it, but the strain had taken a physical toll on me. I was tiring, and only succeeded in pushing out the back end of the parasite this time.

“No, no! Please, take it out! Please!!” I wailed loudly, realizing I was helpless to stop the slug from embedding itself inside my body.

Our tug-of-war would not continue for much longer. With yet another vigorous wriggle the creature again forced itself into my bowels, but now the combined effects of exhaustion and the muscle relaxant were too much for me to overcome. I screamed at the top of my lungs as I saw the tail end of the parasite disappear inside me, and my sphincter close up behind it.

“NOOOOO!!” I screamed in panic, much to Hrathr’s delight.

To my dismay, I could feel the parasite mercilessly sliding its way up my rectum, every inch of the way.

“A wonderful feeling, don’t you agree?” the beast master spoke. “The slug’s mucus is a powerful mutagen. As you have now become the parasite's permanent host, it will now start to modify your body to suit its needs, and adapt and prepare you for your life as a war beast cock sleeve.

“It’s transforming the lining of your intestines, rapidly forming new nerve endings and rewiring your nervous system. Your digestive tract will become highly sensitized, allowing you to derive intense sexual pleasure from it, including your mouth. Like your asshole, your lips and tongue will become even more sensitive than your clitoris. Your throat will effectively become a second pussy, resulting from the growth of nerve endings and a complete suppression of your gag reflex.

“Simply put, it’ll soon be far more enjoyable for you to be fucked in the ass and mouth than it ever was vaginally.

“Once fully established it will be an integral part of your body. Surgical removal, even if it were possible, would result in death, since over time the slug’s tissues become extensively intertwined with yours. You will exist solely to provide the parasite with its needs - in return it’ll supply you with the energy you need to thrive and survive.”

I wailed frantically in terror, but strain as I might I was no longer able to expel the creature from my fundament. It kept making its way upwards, slithering from my rectum into my colon. The Caribou, seeing that the parasite had successfully lodged itself inside of me, then blindfolded me.

“Enjoy this, Cock Sleeve. Rejoice, for you will be made anew and be all the better a slave for it,” he said before leaving and locking the door behind him.

————

In the darkness, I became aware that my body was changing.
Deep inside me, the creature was releasing large amounts of hormones designed to modify my physique and manipulate my mind.

I was almost hyperventilating, trembling with shock and fearful of what I would become. I could feel the slug twisting my body and invading my mind; over time these alien sensations became ever more pronounced and intense.

Slowly but surely strange thoughts and cravings started to enter my mind, replacing the sensation of horror. At first they were momentary pangs of desire and lust, but soon they developed into a strong need to have my rectum and mouth filled. Realizing the parasite was rewiring my brain, I refused these perverse fantasies as much as I could. But the more I repressed them, the more intense these feelings became, until I could no longer focus on anything else.

I started hungering for sperm, experiencing an overwhelming need to taste it, to savor and swallow it. I wanted to have my mouth and throat filled with cock. I lusted for its taste, scent and shape. For the first time in my life I craved for something, anything, to ravage my rump.

And all the while the sensitization of my body continued. I was soon able to notice even the tiniest twitch, wriggle and pulsation from the slug within me, and to my horror its touch was starting to feel pleasurable. My anal cavity was becoming highly sensitive, and to my consternation it wasn’t long before I also started noticing the effect inside my mouth. The slightest brush of my tongue against my lips or palate resulted in ever increasing sexual pleasure, which worryingly was accompanied by a corresponding increase in libido.

At the same time, the parasite started developing my hips in order to attract war beast males, and to make me physically capable of taking their enormous cocks up my rear. The hormones the slug released were gradually forcing my hips to widen and my rump to flesh out, perversely sexualizing my body for both men and the animals’ pleasure.

It was both horrifying and terribly humiliating. But worse than my physical corruption was my complete powerlessness to stop it. Although I was in full command of my faculties, there was nothing I could do to stop the slug from taking control of my senses, urges and instincts. It was slowly but inevitably twisting me to serve its purpose. I no longer had a horn, no magical abilities nor a dream world to escape to. Consumed with lust, I started experiencing feral impulses that became less distinguishable from my own thoughts and desires as time went on.

I could feel my vagina throbbing. My nipples and clitoris were fully engorged, and my body was screaming for pleasure. This unnatural state of estrus was so intense that I felt like my body was on fire. I was sweating and dripping with pure sexual craving, aching for some relief.

Then, Dainn appeared before me.

I could smell his cock. His musk triggered an overwhelming sexual response in me, unlike anything I had ever experienced before. It aroused me to no end, and before I knew it I was winking and squirting, hoarsely inhaling his pheromones like a perverted animal. The parasite was altering my senses and taking control of my mating instincts.

“Hnngh!! Oooh!” I moaned uncontrollably.

It was uncouth and highly undignified, but my desires of the flesh completely overrode any rational thought. Try as I might, I could not wrest my mind from Dainn’s penis. I needed him inside of me. I needed his sperm.

“Good. You are ready to be imprinted, my slave,” the fiend spoke. “It seems like you are particularly compatible host, highly responsive to the physical and mental changes induced by the parasite. It will shape you into an exceptional anal slave once it is fully established.

“But as your master I demand more from you. Although you will always crave war beast semen, after implantation there is a short window during which the slug, and by extension its host, can be specifically imprinted on any male’s sperm. This provides the parasite with additional energy during the infestation process, resulting in more vigorous growth and more thorough modification of the host female.

“The process will fully realize your talents and chain you to me on an instinctual level, turning you into the sex slave you were always meant to be.”

“Hnghh…how dare you do this to a princess of Equestria, you scoundrel!” I managed to snap at the usurper in a brief moment of lucidity.

“You are a princess no longer, Cock Sleeve,” Dainn spoke sternly. “You are a sex slave, and as such you are my property. As your owner I can use you however I see fit. You would do well to remember this.”

“Never…ooh…you’ll never be my master!” I spat at him as I tried to calm down my breathing.

“Many fresh cunts start out with your resistive and recalcitrant attitude. Few manage to maintain it throughout the process of training and reformation. How long will you last, I wonder?” the barbarian chieftain spoke mockingly.

Dainn reached for my face, scratching me behind my ear as if I were one of his pets. I shook my head in refusal of the Caribou’s advances, which merely seemed to entertain him. Sliding his hands along my curves and down my body, the savage grabbed a good feel of my rump. I hated myself for letting out an audible gasp in response. To my disgruntlement, it felt good.

“Mmh, you’re starting to fill out nicely, Cock Sleeve. Once the transformation is complete you’ll be a sight to behold,” Dainn commented, slapping me on the cheeks.

The idea disgusted me, but I could do little more than attempt to control my urges. I was in the close presence of a male, and the parasite was doing its utmost best to compel me to mate with him. It was modifying my senses, making me more acutely aware of his scent and pheromones. I could feel a strong attraction to him, a deep craving for his body which became harder to resist by the moment. A puddle of my shame was pooling between my legs. I was soaking wet, and the warlord knew.

“Haaahh!! Hnnngh!!” I moaned involuntarily as he reached his hand between my legs, running his fingers along my sex.

It felt incredible. To my consternation, the sensitization process was progressing quickly, allowing me to experience extraordinary levels of pleasure. For a moment I tried to fight my traitorous body, but it was of little use against the bull’s skilled fingers. Nothing I did could dislodge him or otherwise prevent him from drawing out several loud moans, and to make matters worse the Caribou lord soon started focusing his attention on my love bud.

His touch felt heavenly. I am ashamed to write that Dainn quickly reduced me to a moaning, horny mess. I lost complete control, grinding my hips against his slick fingers; the bull for his part read me like a book, feeding off my reactions to pleasure me just the way I liked it.

It wasn’t long before I climaxed. My body tensed up and my mind went blank as waves of pleasure completely overwhelmed my body, leaving me screaming, shaking and squirting wildly. Dainn left my shuddering body hanging limply from my shackles while I experienced pure sexual bliss.

“Beautiful,” the Caribou commented. “You’ll be the envy of the nation with a clitoris like this.”

Still panting heavily and slowly coming to my senses, I was not sure of what he meant. But when he removed my blindfold, I could only watch in shock when I saw what was happening to my body. Under the effects of the parasite’s hormones my love nub had hugely swollen, emerging fully from my clitoral hood and jutting outward from my labia. How he could consider such grotesque deformation to be beautiful was beyond my understanding.

“N-no, no! This cannot be true!” I cried, fighting back the tears in disbelief.

“Modification of the host’s sex organs is part of the bodily changes the parasitic infection induces. The slug requires large amounts of semen for its nutritional needs, and it’s therefore in its interest to transform you into an insatiable slut. An enlarged, highly sensitized clitoris is but one of the methods it employs to turn you into a nymphomaniac unrivaled in sexual appetite. Fortunately we have the tools to use this to accelerate your development into an exceptional anal slave,” Dainn spoke while reaching into his pocket.

He revealed a smooth silver ring that despite its rather simple appearance emanated the chill of powerful Caribou sorcery. It made me shudder to think what horrible, corruptive enchantments it had been infused with.

“This ring is imbued with my personal magic - a spell of control, as well as one of arousal. It will inhibit all clitoral and vaginal orgasms without my express permission, and will keep your body in a heightened state of heat. From now on, anal sex will be your primary form of relief,” the warlord said, before pushing the ring against my swollen clitoris.

“No! No please!” I wailed, exasperated at this unexpected act of cruelty.

But there was no escape, no matter how much I twisted and struggled to shake the fiend off of me. His fingers had left me completely slick, and the ornament easily slid over my swelling love bud.

“Noooo!!” I screamed, desperately trying to shake of the ring somehow.

“It’s futile, Cock Sleeve. As your body develops and your clitoris grows, this ring will be permanently locked in place,” Dainn spoke with satisfaction. “Consider this a gift to you as my slave. It will serve as a permanent reminder of your status as my sexual servant, and a sign of my favor.

“It will aid in your transformation over time, and will mold you into a magnificent anal slave.”

“Never! I will never be your anal slave!” I screamed in absolute rejection of the notion.

“On the contrary, your development is already well underway. You are mine now, cunt. You serve only a single purpose now, to be fucked in your mouth and asshole,” the fiend spoke as he moved behind me. “But don’t worry. It will be a uniquely pleasurable experience.”

I felt the savage’s hardening penis press between my cheeks. My conscious mind was utterly repulsed by him, but my carnal instincts were now completely controlled by the slug. My body craved his cock, and to my great shame I felt myself involuntarily pushing my rump against it while I winked and squirted uncontrollably.

“Good girl, Cock Sleeve. Looks like your asshole is ready,” Dainn spoke gleefully, guiding the tip of his member to my sphincter.

“No!! Don’t you dare!!” I shouted at the Caribou.

It was of little use. With a powerful thrust of his hips the bull forced his erect manhood inside me up to its hilt, filling and stretching me to my limit.

To my surprise, his shaft easily slipped inside my rectum. The initial shooting pain of anal penetration turned into sexual pleasure almost instantly, and I could feel every little bit of his huge cock moving inside me, from its ridges up to its flaring tip. And I am loath to admit that the feeling was exquisite - it felt as good as vaginal sex, if not better.

Dainn was fully aware of this. What little resistance I could muster withered away instantly when he started rhythmically pounding my rump, to my begrudging delight.

“Aaahn! W-what…ooh…is happening to me?” I exclaimed as the Caribou quickly reduced me to a moaning mess.

“Feels good, doesn’t it? The slug greatly sensitizes its host’s intestines and further modifies your perception of anal penetration, allowing you to feel enhanced pleasure. In addition it mutates the lining of your bowels, forcing it to produce lubricant to facilitate anal penetration,” Dainn answered. “The speed of your physical development defies my expectations for you, cunt. It seems like you’re uniquely compatible with the parasite. You were truly born to become my anal slave.”

I could barely formulate a response. I found myself almost thrusting my hips back onto his cock as hard as he was fucking me, losing myself completely in sexual ecstasy. It was intense, instinctive, almost feral. And it was equally enjoyable for the bull. He reached for my breasts, groping and fondling me as he grunted loudly. The warlord fully indulged in my body, gradually pumping his cock harder and faster; I soon felt his tip expand, stretching my insides even wider apart.

The Caribou came with a loud roar, gripping my body firmly and repeatedly hilting himself inside me. The feeling of Dainn’s pulsating cock ejaculating his filth inside me triggered an orgasm that I can only describe as otherworldly. I was overwhelmed with sheer sexual joy combined with a feeling of intense fulfillment and bliss, such that it left me moaning, screaming and gasping for air. My whole world shook and trembled as I squirted wildly. Raw pleasure overloaded all of my senses, and I lost consciousness.

————

When I came to I found myself once again restrained in complete darkness. I was lying on the floor with my wrists and ankles tightly bound together behind my back with rope. A penis-shaped gag had been locked inside my mouth, which reached deeply down my throat. My head was covered by a hood, isolating me from my surroundings - it was in this helpless state that I was left to experience Tartarus.

Having been fed by Dainn, the slug was now growing in strength and vigor. It was no longer moving but focusing its energies on fusing with my body, spreading its tendrils throughout and effectively becoming an organ with me. And all the while the parasite continued to release large amounts of developmental hormones, which raged within me and further transformed my physique to suit its purpose.

To prepare me to mate with the giant war beasts, the slug was further altering the bone structure of my hips as well as the size of my rump, ruining my physique and leaving me with a perversely voluptuous figure. I could feel my clitoris throbbing and swelling - Dainn’s ring gripped me tighter and tighter as time passed, until the ornament was completely locked in place. My lips, mouth and tongue were continuing to develop in sexual sensitivity as well. As a result I soon found myself begrudgingly enjoying having my throat stuffed by the large rubber sex toy.

Throughout the entire ordeal, my state of arousal only increased. I struggled to resist the creature’s directive - a powerful, instinctive urge to have my mouth and anus filled. I was hungering for males, for cock, for semen. Depraved thoughts increasingly pervaded my mind until I was completely consumed by them, barely to think of anything but sex and masturbation. My nipples were almost painfully erect, begging to be touched and reacting to the merest waft of air flowing across them.

It was estrus like mare was never meant to experience. It was maddening, and it required a sustained mental effort not to give in to lust or indeed the fear of what I was becoming. My heart went out to other ponies that had similarly suffered my appalling fate. No doubt a lesser mare would have crumbled and broken completely under such duress. I steeled myself, vowing to fight the Caribou’s designs until the very end.

But the intent to resist was the only thing I could manage in my hopeless position. To my great frustration the ropes tightly restrained me, barely allowing me to move a muscle. No matter what I tried, I was unable to break free or indeed find the relief that I so desperately craved. My powerlessness and utter lack of agency in this situation was vexing, and I could do little more than hope for rescue.

————

By the time Dainn returned several days had passed. The longer I went without a load of sperm, the stronger the parasite’s hold over my desires became; after this period of abstinence my cravings had degenerated into a ravenous hunger for cock and cum. The moment I caught a waft of his scent I involuntarily let out a lustful moan.

“Mhh! Hhhghh!!” my muffled voice sounded as I hoarsely inhaled the air, searching for the source of the musk.

“Hmm, excellent. It looks like your transformation is progressing well, Cock Sleeve,” the Caribou spoke as he kneeled down to inspect my body. “Like your sister you are developing an exceptional physique. You two will be quite the sight to behold when you are fully trained slaves.”

I could do little more than moan and shiver as he softly ran his hands along my curves, copping a good feel of my swollen rump. I hated that I let out a squeal in response. But by now I was so starved of touch that I instinctively pushed my cheeks into the bulls groping hands, lifting my tail and hoping for some form of sexual relief.

I did not have to wait long. Dainn raised me up to my knees and removed my gag, pulling the phallic sex toy from my throat. I was met with the scent of his penis and testicles, bared just in front of my nose. My conscious mind planned to bite down hard on the vile slaver’s cock - I would have severed it completely if I could. But my parasite-addled instinct overruled the intent the moment my lips touched his tip. When his cock brushed against the skin of my lips, pure sexual pleasure coursed through my body. Instead of snapping my jaw went slack, welcoming the enormous flesh rod inside my throat.

“MHHHHNNH!!” I moaned loudly when Dainn pushed his member deeply inside my mouth.

My mouth felt…like a vagina. It was raw pleasure, transmitted through my lips, tongue, even the palate and sides of my mouth. Dainn easily slid his enormous length down my throat, which to my surprise I was able to take it up to the hilt without gagging - another perverse effect of the parasitic infection.

I could feel every bump and vein rub against my sensitized esophagus in all the right ways. The girth of his member stretched my throat to its limit, an unfamiliar feeling that very quickly became uniquely enjoyable. The sensation overpowered my last remaining thoughts of recalcitrance, giving way to the singular desire of having him fill me up as much as possible. The Caribou’s musk only added to my arousal; my nostrils flared as I greedily took in his intimate scent.

Gripping me by the sides of my head, Dainn started thrusting his cock in and out of my throat, raping me orally. I am embarrassed to admit that I was unable to put up any form of resistance. It provided me with an opportunity to release my pent up sexual frustration, and to this end I begrudgingly took part in the sordid act. The mutations induced by the parasite were transforming my oral cavity into a sex organ, and correspondingly the orgasms soon started flowing.

I could not help but surrender to pleasure. Climax after climax wracked my body, leaving me moaning, trembling, squirting and squirming in Dainn’s hands. It was a satisfying reward for finally submitting to this depraved sexual experience, although I was loath to admit it.

“Hrrgh…aah…good girl, Cock Sleeve,” the Caribou groaned lustfully. “Does it feel that good to have your mouth turned into a pussy?”

It was undeniable that it felt incredible. But it was equally worrisome that apparently my physical modification had not yet been fully realized. It was clear that besides utterly perverting and sexualizing my body, the slug would force me to experience extraordinary pleasure in ways that should not normally be possible. And I was soon to have a taste of what was in store for me.

The bull soon started moaning louder and louder - he was clearly enjoying the feeling of my tongue and throat wrapped around his cock. His balls slapped against my chin as he savagely started ramming his penis down my throat, his tip flaring in response to the building pleasure. Not that it felt uncomfortable - quite on the contrary.

“Hnngh…I’m going to cum! Enjoy this, slave, and let the taste of your master be ingrained into your mind,” Dainn groaned, gripping my head tightly as he repeatedly hilted his shaft as deeply inside me as he could.

I felt Dainn shudder as his penis throbbed, ejaculating his seed deeply down my throat. The ingestion of cum triggered a strong sucking and swallowing reflex within me, coupled with the intense need to deep throat his cock. Clearly the parasite was changing my behavior, taking control of my instincts to access the semen it required to survive. And as a reward, I experienced a series of otherworldly climaxes.

“HMMMNN!! OOOHHNNHH!!” I screamed as I started cumming wildly.

I felt my eyes roll into the back of my head, unable to think of anything but completely draining Dainn’s testicles as incredible waves of pleasure coursed through my body. The pulsations of his cock kept me orgasming over and over again, and the bull had copious amounts of sperm to feed me. The warlord moaned in ecstasy as he released the last of his load down my throat, but at the last moment of his orgasm he withdrew himself, spilling his semen onto my tongue in the process.



My eyes widened in shock when I tasted his seed. The flavor of it was incredibly strong. To my horror I realized the parasite had enhanced my tastebuds, greatly magnifying my sense of taste and texture.

Dainn’s sperm was utterly repulsive, and I would have spit it out right then and there. And yet, I did not. I could not. Instead of retching, I was slurping it up. I hated it. But I needed it. I needed it more than anything.

I could not help but use my tongue to explore every part of the bull’s shaft as its taste, smell and shape were etched into my soul. Even after he retracted himself I could not resist kissing and licking his penis, rubbing his cock and balls all over my face while I worshipped them.

“Wonderful, it looks like the imprinting process has been a resounding success. You are a compatible host indeed, Cock Sleeve,” Dainn said with glee. “From now on, you will crave my cock and sperm as much as that of war beasts.”

“No, no! ’Tis a lie!” I wailed in abject horror.

But deep down I knew a strong desire had taken root within me. I was barely able to break my lips free from his testicles, and every part of my body was screaming for more.

“This craving will develop as our bond is strengthened, and will eventually become your sole motivation in life. Over time, it will turn you into one of my most loyal and obedient servants, existing only to serve my cock,” the Caribou spoke.

Before I could reject his assumption the savage reinserted my gag, pushing the sex toy down the back of my throat and locking it in place.

“Your physical development has only begun, my pet. I look forward to seeing you once you’re fully fleshed out,” the bull spoke, leaving me fully restrained on the floor before locking the door behind him.

It would be days before he returned. Although the ingestion of Dainn’s seed momentarily allowed me to think clearly, I was still tightly bound. There was nothing I could do to escape. And as the hours passed the parasite started to hunger once more, and my ravenous sexual appetite returned accordingly. Soon I was unbearably aroused once again, driven to seek out the semen the slug required.

Disconcertingly, the lustful thoughts implanted in my mind started focusing on Dainn specifically. As sexual fantasies started to pervade my thoughts, I could vividly recall his taste, shape and scent. Within half a day I was famished, and moaning with intense cravings and unfulfilled lust. Clearly, in order to remain somewhat in control of my faculties, I would have to ingest sperm orally or anally several times a day. It was both a humiliating and disgusting prospect.

And all the while, my physical transformation continued. The slug completely assimilated into my body, fully turning my entire digestive tract into a sensitized sex organ. My rump reached its maximum fullness, now wide enough to able to take the war beasts’ monstrous cocks, and Dainn’s horrible ring now clasped my swollen clitoris tightly. My body was burning up, aching to be mounted and mated. I could do nothing but suffer through my ordeal, and hope for salvation that would never come.

————

When the door of my prison finally opened again, I instantly perceived Dainn’s scent. A mere waft of it triggered an instant, instinctive desire to seek the Caribou out. My nostrils flared as I ravenously inhaled his pheromones, all the while driven by the parasite to search out his cock. To my disgrace I could not help but moan like a depraved animal in heat, desperate for some relief from my lust. Sex hormones were raging throughout my body, leaving me so completely consumed by carnal desires that I could barely think of anything else.

“Magnificent. You’ve become quite the sight to behold, Cock Sleeve. With a body like this, you will be the envy of Equestria,” the warlord said, eying me up before he untied my ropes.

The moment my limbs were freed I almost instinctively reached between my legs, looking to release my pent-up sexual frustration.

“Mnnhhh!! Hnngh!!” I moaned into my gag.

It was shameful and unsightly, but I was not able to stop wildly fingering myself in front of the Caribou. What little coherent thought remained was unable to counteract the slug’s powerful directives. After just a couple of days of abstinence I had lost complete control of my body and its urges.

My clitoris was now enormously swollen, greatly enlarged in size and protruding from its clitoral hood. Although I found it a grotesque mutation, I could not deny that it provided me with greatly increased sexual pleasure. Like the rest of my body it had been enhanced, and was highly sensitive to the touch - despite my indignation at my physical corruption, I could not help but masturbate vigorously.

It should have been a quick release, but for the accursed spell engraved into my clitoral ring. Just when I was about to orgasm Dainn’s infernal rune magic activated. The icy chill of his power flowed through my loins and my very being, pulling me back from the brink and denying me my pleasure, keeping me highly aroused and frustrated.
 
“Let this be a lesson, slave,” Dainn spoke sternly. “Know that I control your body, and that you are my possession. Only through my express permission will your pussy ever provide you with the pleasure you seek.”

I could only grumble in response. The bull then removed my gag and to my surprise…kissed me. The touch of his lips against mine felt uniquely pleasurable. It was clear that the parasite had developed my lips and mouth even further, increasing the sensitivity to surpass that of my vagina. Any remaining thoughts of resistance melted away as the Caribou locked his lips with mine, pulling me in by placing his hand on the back of my head.

“Hnnmh...mmh…” I moaned with delight as we kissed and our tongues intertwined.

It was unnatural, raw sexual pleasure. My tongue now felt as good, if not better than my modified clitoris. To my great shame I found myself leaning into my enslaver, reciprocating his advances. In my parasite-addled mind everything about him was arousing. The way he smelled, how he tasted. The way he kissed and tongued me, and wrapped his strong arms around me. The way he took control of me.

Disgracefully, I found this innervating experience to be greatly enjoyable. It wasn’t long before I orgasmed, which left me breathless and squirting in the arms of the man who had personally collared me. As my trembling legs gave out underneath me, Dainn took a firm hold of my body, keeping our lips firmly locked together. I had no choice but to submit to pleasure. His kisses kept me cumming and cumming in his arms, until the brute finally released me.

“Excellent, good girl. It’s rare for a host to develop such high oral sensitivity. You were truly born to become my anal slave, Cock Sleeve,” Dainn spoke with satisfaction.

His comment barely registered with me. I lay on the floor at his hooves as my body convulsed and spasmed in passion. I hated what the Caribou had done to me. I hated how they had succeeded in corrupting my body and perverting my mind. But I could not deny this had been one of the most pleasurable sexual experiences of my life.

As my senses slowly returned to me, the bull removed the hood from my head. After such a long time spent in total darkness it took a little while for my eyes to adjust to the light, but soon I could clearly see my enslaver standing in front of me. I only had an eye for one thing - his large, bared genitals.

I flung myself at him like a famished beast, unable to control my urges. Lust overrode any remaining notions of modesty, and I shamelessly started kissing and licking the Caribou’s balls. It was feral, animalistic physical attraction. Any mental objections to this immoral sex act were overpowered by the parasite’s directive to its host - to seek out sperm. And seeing me in my state of heat, under complete control of the slug clearly aroused the warlord. His shaft soon started stiffening, extending from its sheath and rapidly reaching full erectness. I was instantly drawn to it, rushing to envelop Dainn’s veiny cock with my now fully sensitized lips.

It felt even better than the last time the Caribou raped me orally. I plunged his penis as deeply down my throat as I could, sucking the bull off in a wild, unbridled fashion.

“Haargh!! Marvelous, slave!” the savage grunted with ecstasy as I worked his massive member.

With my gag reflex completely suppressed, I easily made my way up and down the full length of his penis, from his tip all the way down to the base of his sheath. Every bump and ridge rubbed me in all the right places, and gratuitous pleasure flowed from my lips, tongue and mouth. And the bull similarly enjoyed himself. His flaring of his cock stretched out my throat, sending even greater pleasure coursing though my body. I could not help but moan like a harlot, knowing that my prize was about to pour into my stomach.

But suddenly, the bull grabbed me by my mane and pulled his member out of my mouth. Perplexed, I lunged for his cock, seeking to sate my ravenous hunger for sperm. But Dainn’s grip was firm, and he forced me face down onto the floor of the prison, raising my rump up into the air.

I did not resist him, nor would I have been capable of doing so. Instead I squealed like a common harlot when I felt his tip push against my sphincter. With a smooth thrust of his hips, the Caribou effortlessly slid his penis inside my body.

It felt like the first time I was anally penetrated. I felt momentary discomfort as his enormous girth stretched and split me apart - but the pain was soon replaced by otherworldly pleasure. The lubrication of my innards meant that Dainn was able to probe my depths unopposed, and the brute inserted himself fully.

“Hrrggh! Your asshole is gripping my cock like a vice!” Dainn grunted lustfully as he pushed his shaft up my backside. “It’s incredible how much you’ve tightened up!”

Being filled up and stretched like that activated something primal in my brain, a feeling of intense satisfaction, fulfillment and bliss. By now my anal cavity had been fully developed by the parasite, allowing me to feel every movement of the warlord’s penis deeply inside my bowels. It felt better than the best vaginal sex I had ever experienced, overwhelming my senses no matter how much I tried to refuse it. Although I was aware of the parasite’s influence on my mind, I could do little more than moan as Dainn started ploughing me roughly. The slug was in complete control of my urges, and I could do nothing but comply.

The Caribou equally lost himself in ecstasy, copping a good feel of my swollen rump and slapping my butt cheeks roughly as he pounded my backside. I could feel his cock flaring once more - he was about to cum.

“Beg for it, whore,” Dainn whispered into my ear. “Beg your master to cum inside your asshole.”

Had I been in full control of my faculties, I would have refused to comply with such a demand. But I was consumed with an all encompassing craving for his seed, and in my state of hunger I could no longer help myself.

“Hngh…ahh…p-please master…cum inside my ooh…asshole…” I muttered.

“Again, Cock Sleeve! Speak clearly when addressing your master!” the bull demanded sternly.

“Please Master Dainn, cum inside Cock Sleeve’s asshole!” I cried, much to the Caribou’s satisfaction.

“Good girl,” his praise sounded. “Now, enjoy the cum you so desire.”

Within a few hard thrusts, I felt Dainn’s cock throbbing, injecting his filth deeply inside my bowels. The orgasms started flowing as soon as he ejaculated, a powerful physical reaction to the Caribou’s semen induced by the parasitic infection. What little free will remained within me detested being made to orgasm in such a depraved manner, but I was powerless to stop myself from climaxing. The bull’s fingers dug into me as he gripped my hips, hilting himself continuously while he fed me the sperm I needed. I was forced to cum over and over again, moaning like a whore while being raped by my enslaver.

It was in this utterly sordid and perverse union of bodies that I was filled with an intense feeling of complete satisfaction, joy and sexual bliss, unlike anything I had ever experienced before. Vexingly, the slug was manipulating my mind, seeking to reinforce my behavior. I was too exhausted to fight it however, and when the bull retracted his cock from my fundament I collapsed onto the floor, losing consciousness.

————

Dainn returned to violate me repeatedly over the following weeks, purposefully leaving several days between visits to ensure the parasite was starved and I was fully receptive.

To my frustration this simple method of imprinting was extremely effective. Against my will, my physical attraction to the Caribou became stronger with each session, and my hunger for his seed ever more voracious. Although mentally I resisted fiercely, I quickly developed a strong physical reaction to his presence. I became highly sensitive to his scent and pheromones and was unable to stop the strong sexual arousal I developed in response. Despite its repulsive taste, I grew completely addicted to Dainn’s cum, such that my depraved lust for it never truly abated even after hours of sex.

Over time, the parasite’s will seemed to blend with mine, making it difficult to distinguish which thoughts and impulses were truly my own. Now fully established and gaining in strength, the slug was in full control of my sexual instincts and desires, and was slowly warping me into a sperm-crazed nymphomaniac. Perverse thoughts pervaded even my dreams, implanting sexual fantasies into my mind as my body desperately sought the release it so desperately needed.

As the hateful bond between master and slave strengthened, so did I begrudgingly learn to enjoy my developing body. The sheer pleasure that oral sex provided me made me think how I had managed to live without it for so long, and the incredible orgasms I experienced when Dainn ejaculated inside me were truly heavenly. No matter how long the fiend raped me with his massive cock, by the next time he returned my rectum seemed to have tightened back up completely, allowing me to experience the full stretching of my anus time and time again.

Mentally I was acutely aware of how immoral and repulsive my thoughts were, but in my ravenous state I was entirely unable to suppress my carnal desires. The Caribou lord took full advantage of me, using my extreme arousal to make me beg for his cock. To my disgrace I could not resist submitting to his will, sucking and riding his cock while cumming wildly like a sex-crazed beast.

————

When Dainn finally led me out of that horrible room I was a changed mare. I had to fight back the tears when I saw my reflection in a mirror. My sleek elegant shape had been ruined, corrupted into a voluptuous, sexualized figure. The parasite was now an inseparable part of my body; I had become little more than a repulsive sex organ. Hormones are raging through my body, imbuing me with seemingly endless lust. Maintaining my self control is a continuous, laborious task, and despite my best efforts it is clear that it is impossible hold my instincts at bay forever.

As such, I cannot see how a return to a normal, respectable life will be possible. The quantities of semen I require to satisfy my hunger are considerable, meaning I would have to spend most of the day feeding - a habit I will need to follow for life. And even when satiated, my lucidity only lasts a couple of hours before I am once again overcome by arousal, to the point that sex consumes my every thought and desire. Even as I write this I struggle to concentrate, and my hands have strayed many a time.

I must admit to feelings of despair, but I must not bemoan my doom. I must remain strong for my ponies, regardless of what will become of me. Others may be subjected to worse fates, difficult though it may be to imagine. My suffering matters little in the grand scheme of things. As long as we can make it through, surely we will be able to rebuild our society despite the Caribou’s efforts to pervert and corrupt us all.

I will never submit to the Caribou as long as I draw breath. Whatever these vile barbarians’ plans for me are, I shall repudiate and reject them utterly. It is my duty as a princess of Equestria.
