I am no longer aware of how much time has passed. The past period has been spent being subjected to relentless mind alteration for what seems like an eternity. To my dismay, I can no longer deny that my masters’ reeducation efforts are having their desired effect. Now that I know what Hrathr expects of me, I have settled into a routine, finding that compliance is in many cases easier on the body than resistance. Not too long ago I would have considered obedience absolutely out of the question, but recalcitrance is met with punishment in equal measure, and pain is a harsh mistress. Even though my spirit remains uncowed, over time I have found myself more and more inclined to follow Hrathr’s commands, if only to avoid the sting of the whip.

My revolting diet of bodily fluids has continued as before, and although I cannot say I’ve come to like my feed, the addictive properties of war beast semen are evidently potent. I am…definitely developing an affinity to it. Hrathr knows this, undoubtedly having observed that I now swallow my meals with little of my earlier disgust and retching. In addition to this, the arcane whispers that talk into me during my conditioning sessions seem louder and clearer every day; I can clearly identify them as runic chants in the Caribou’s strange tongue. I have no doubt they form part of an enchantment of sorts, chaining my mind and bending me to their will in subtle, gradual ways.

Being aware of the effectiveness of the Caribou’s training methods has made the need to escape my bonds all the more pressing - yet this is considerably complicated by the helpless state I am left in when I’m not being worked on. Although Hrathr is fond of repeated, exhaustive drilling and conditioning sessions, I am allowed the occasional day’s rest, presumably for my own health. On these days I am normally left restrained in my cage with my wrists shackled to my ankles, covered in latex from head to hoof. My vision and much of my hearing are taken away by a hood that fully covers my head, leaving only my muzzle uncovered. To complete my degrading outfit my mouth and crotch are stuffed with the all-too-familiar casts of Dainn’s manhood. With all my senses taken away, I am left to suckle helplessly on my enslaver’s cock, further strengthening my wretched imprinting.

Despite the continued mistreatment, the Caribou do ensure that I am well-fed, if only to keep me in physical shape for training purposes. Iron Lance would enter my cell three times a day, removing the toy lodged inside my mouth to allow me to ingest my disgusting feed. Often he would force me to seek out my bowl by its scent alone; the guard evidently found it entertaining to watch me wiggle along the floor, following my nose to reach my meal. It is horribly disgraceful for a princess to worm her way to a dog bowl, sniffing for her food like an animal and being made to drink another beast’s sperm of all things. But I bore through it, knowing that it was through this stallion that I would be able to break out of my prison.

After repeated visitations Iron Lance eventually devised a little game; he would sit down in different parts of my cell each time, forcing me to find him by sniffing out his cock and balls. Only when I successfully made my way over to him would he take out my mouth plug, before pouring my feed into the bowl. I would bury my muzzle into my cum, greedily slurping it down with hoarse moans in the manner of slaves. I could bear the indignity of licking my bowl clean, continuing my act by begging him in my raunchiest voice to fuck my trained cunt, to ravage me and fulfill his most perverted desires before the king would claim me for his personal use. Resisting defying orders and breaking discipline, he declined each time, instead commending me on my developing sluttiness before reinserting my dildo and returning my to my cage. My failed attempts were disheartening - they meant I had days of intensive training to suffer through before the opportunity would rise again. But just as my hope was starting to falter, Iron Lance finally took the bait.

This time, after promising him the wildest, most depraved sex he could imagine, the stallion stayed silent. I anxiously awaited his response, being unable to see, but it was clear to me he was contemplating my offer. After a few awkward moments he spoke:

“Get up, you filthy whore. You have a cock to please.”

In a strange way, his answer was liberating. I squealed with delight, excited that at last he had fallen for my ploy. The next step of the plan was to wear him out and take the keys to my prison while he was asleep, after which I would attempt escape the castle and unite with the resistance that was undoubtedly being organized. The prospect was exhilarating, but I had to calm myself - my task was just starting, and if I couldn’t completely exhaust Iron Lance physically it would all be for naught. In addition, I was still restrained and unable to see; in my current state I would be going nowhere.

It was quite the effort to raise my body off the ground, but after a brief struggle I managed to reach his crotch, and set to work. As I sensually lathered my tongue over his family jewels I could feel his member engorging itself, emerging from its sheath and pushing along my cheek as it hardened. For the first time since my capture I felt satisfaction while giving head. Finally things were proceeding on my terms - although Iron Lance certainly didn’t seem aware of it, being too engrossed in his ridiculous male power fantasy. I savored every ridge and vein as I worked my way up his full length, and dutifully sank his cock into my throat.

Hearing him moan as I plunged his rod down my throat was deeply gratifying. I now had Iron Lance fully aroused, and would easily be able to wrap him around my finger. I took perverse pleasure out of servicing him orally, knowing that although I wouldn’t be able to get him to roll over and snore with a simple blow job, it would at least bring me closer to my objective. It wasn’t long before I felt the tip of his cock flaring, indicating that he was about to cum. Letting out a loud groan, the stallion roughly grabbed hold of my head, powerfully inserting the full length of his cock into my mouth. His deep, rhythmic thrusts almost dislocated my jaw, but I wasn’t about to let up. As soon as I felt him pulling back to try and prolong his pleasure I redoubled my efforts, pushing my throat back onto his cock and sucking it as vigorously as I could. He climaxed almost instantly, moaning loudly as he ejaculated his essence into my mouth with each throb of his penis.

Unlike with other stallions, I had no qualms swallowing Iron Lance’s seed - it was a necessary means to an end, essential to keep up my guise. Capitalizing on the moment, I continued pleasuring him with my tongue as he continued climaxing, taking his shaft deeper and deeper with the knowledge that each throb of his stallionhood, each disgusting burst of baby batter would take me closer to my ultimate goal of escaping this hellish prison. Iron Lance had few complaints. Going by his grunts, pants and groans, being serviced by his former princess was clearly ecstasy for him.

“Haah…Ngh…by the king you’re turning into a magnificent cumslut. I have to admit that I am somewhat envious - he’ll get to enjoy Equestria’s most exquisite cunt once you are fully trained,” the royal guard’s praise sounded.

A long-awaited, crucial moment had arrived. In order for my breakout to be successful, I would need to somehow convince Iron Lance to undo my restraints. Luckily stallions have a one-track mind nowadays, and knew just how to trick him into aiding in my escape.

“Thank you master, Master Hrathr and Master Anvari have taken great care to train this slave in compliance with Caribou customs. But Sun Slut has much more to offer you, Master Iron Lance. Please, untie my ropes so this cunt can pleasure you to the full extent of her abilities,” I replied, trying to appear as vacillating as possible by kneeling in front of him.

To my great delight, Iron Lance fell for my ploy. He removed my hood, untied my restraints and stripped me of my bodysuit, copping a good feel of my exposed breasts in the process.

“Such marvelousness. Soft and supple, yet as large as the bustiest of young mares” the guard’s denigrating assessment sounded. “You did your ponies a great disservice by hiding these tits from us. Like many a stallion I lusted for them, but never thought that I would ever get to see them, let alone fondle them before the Caribou liberated us. But now King Dainn has finally set this injustice straight,” Iron Lance said, tossing my robes aside.

I did not appreciate his crude comments nor his groping hands, but tolerated his transgression. Most importantly I was now freed from my restrictive rubber outfit, no longer blindfolded and had regained the use of my arms and legs, although Iron Lance left my boots and gloves untouched. Ideally I would rid myself of these as well since my paw gloves prevented the use of my fingers. Aware that these formed an important part of my new “identity”, I decided not to push the envelope too far so as to avoid suspicion.

“I now understand how wrong I was, thanks to Master Hrathr’s teachings. I was a haughty fool who did not know her place; a whore’s body is to be enjoyed by all,” I managed to utter, somehow managing to feign a smile.

“The lords’ hand in raising you is evident. I must admit I had my doubts whether or not they would be able to reform you into an obedient cunt, knowing your royal nature. Clearly, I was mistaken in my lack of faith,” Iron Lance spoke as he crouched down to pet me on the head. “Despite all the majesty and dignity you displayed, you must have always been a depraved slut behind the scenes for such a radical change to occur. Our king was right to select you to be trained into his personal sex slave, evidently possessing much greater insight in his subjects’ character than I do.”

“Of course, Master Dainn was right about my potential. Like any mare I am a wanton slut, but my true character was suppressed by false notions of modesty and equality. Master Dainn has opened my eyes to what I really am, and this bitch is glad to be taught to serve him,” I replied, attempting to allay any distrust by recanting the preposterous Caribou doctrine I had been forced to memorize.

Apparently satisfied by my response Iron Lance reached into his pocket, revealing a flask containing a translucent green fluid. He popped off the cork and took a large swig, before offering me the rest of it. Wary of taking any Caribou potion, I was apprehensive but aware that refusing would do little to help my cause. At his command I opened my mouth, after which he pressed the bottle against my lips and poured its contents down my throat. It did not taste as foul as I expected - it was certainly organic, probably plant based with a tinge of sweetness mixed into it. At the very least the liquid washed the aftertaste of stallion cum from my tongue.

Its effects were soon to become clear. Iron Lance’s cock engorged itself once more, reaching full, veiny erectness within seconds. It was an aphrodisiac, and a powerful, fast-acting one at that. I panicked as I felt my nipples engorge and heat emanate from my sex, aware that I could ill afford to be distracted from my task by raging sexual urges. My breeding instinct was running wild, taking over my rational thoughts; a loud moan, my winking, slick pussy and an involuntary squirt all but confirmed my heightened state of estrus. There was no escaping it now, much to Iron Lance’s delight. It took a titanic effort just to remain focused. But rather than giving in to lust, I would use this potion to my advantage - forcing me into a state of heat would make it all the easier to sexually exhaust the unwitting guard.

Taking the initiative I spread my legs as wide as I could before Iron Lance, eying him up lustfully and begging him to ravage my horny slave cunt. Needing little prompting, the stallion was on top of me within moments, sliding his erect shaft into my sex and rutting me on the floor like a ravenous beast. With his mind overtaken by lust he sated his desires, paying little heed to my own pleasure and using me as little more than a fuck toy. He roughly groped my breasts and sloppily locked lips with me, forcefully slamming his hips onto mine as he hilted himself with each thrust. Under normal circumstances I would not enjoy a man taking me in such a manner, but by now the aphrodisiac was coursing through my body and it took little effort to act the part of a harlot. Truth be told, the feeling of his cock was enough to push me towards the brink; having my chest fondled only added to the experience. I must admit, somewhere deep down a part of me enjoyed being used like this. It was rough, primal sex, a stallion and a mare driven wild by lust and indulging in their most basic instincts. As soon as he unlocked his lips from mine I threw my head back and let out a coarse moan, surrendering myself to pleasure, much to Iron Lance’s delight.

“That’s it, moan you cunt! If only the other guards could see their princess now, blossoming into Equestria’s most perverted whore!” the royal guard sneered, crudely feeling up my breasts as he continued forcing his full length in and out of my most sacred place.

I could only squeal as he squeezed my nipples. The drug-enhanced pleasure felt electric - for me and for Iron Lance. His breathing was ragged, and his hoarse moans betrayed his increasing excitement as he steadily increased his rhythm. His rock-hard member rubbed me in all the right places, working me ever closer to the climax I so craved. I had little doubt that the stallion was only interested in his own gratification, but in my state of arousal it made little difference. With a burst of fast, powerful thrusts he made me cum as hard as I ever had, reducing me to a trembling, squirting mess. My tightening walls reciprocated in kind, squeezing down on Iron Lance as my body was overwhelmed with lust. I felt his stallionhood throbbing almost instantly, pumping its payload into my womb. The royal guard moaned loudly as his rhythmic thrusts became irregular, riding out an orgasm of his own. But rather than pulling out, he continued humping me vigorously. To my surprise I could feel his cock engorging itself once more, reaching full mast only moments after cumming.

“Heh, excellent!” Iron Lance exclaimed as a wide grin stretched across his face. “It works as well as they say it does!”

I understood exactly what he meant. My hormones were raging, and the aphrodisiac coursing through my body was pushing my sex drive to new heights. His scent and pheromones only added to the experience, and for the first time in ages I found myself truly enjoying having sex, rather than having pleasure forced upon me. I wrapped my legs around him, giving him a sultry look as I gazed deeply into his eyes, all the while encouraging him to continue pumping away. It took little effort to convince him to oblige - which was just what I was after.

Iron Lance would continue to defile me for hours on end. As Hrathr would say, we fucked like beasts - there was none of the gentle, tender lovemaking I once enjoyed as a princess. It was hard, animalistic; only our individual satisfaction mattered. Rather than sating me, each climax sent me soaring ever higher, seemingly only increasing my desire and making cumming all the more satisfying. We changed positions frequently; Iron Lance would take me pressed against a wall, bent over one of the seats, on the ground, and in whatever creative position his perverted mind would think up. I would be lying if I said it wasn’t pleasurable, even if the experience wasn’t a natural one. Orgasms flowed freely and I indulged in them, often losing control completely as his hard cock sent me over the brink time and time again. A common mares’ complaint is that stallions do not last long enough to guarantee our satisfaction - here I received plenty, and then some.

It was physical rather than sexual fatigue that eventually halted our sex romp. Panting, Iron Lance finally withdrew himself after ejaculating his seed inside my womb once more, stumbling towards a bench in the corner of my cell to catch his breath. We were sweaty and exhausted - but I needed more, and gauging by the still-erect rod between the guard’s legs, he had more to give me still. I crawled over and took his throbbing penis into my mouth, enjoying the musky taste and scent of his cock and cum, mixed with my own fluids. A loud groan of pleasure escaped his lips as I squeezed his shaft between my breasts, rubbing them along his length and pleasuring his tip.

“Hnngh, marvelous! You’re becoming as insatiable as Cadance!” Iron Lance said, smirking. “The lords truly have done an incredible job converting you into a filthy little slut!”

“Thank you, master. No amount of cock can ever be enough to sate this depraved sex slave,” I answered with a smile, looking up briefly before resuming my task.

It was insufferable to continue spouting the insulting diatribe the Caribou had taught me, but I knew my objective was near. Worn out as he was, the stallion would not be able to carry on much longer. As expected, it did not take much effort to work him up to his limit. Although I am not accustomed to and certainly not proficient at pleasing a man with my breasts in this manner, I nevertheless found him reacting positively to my rather awkward efforts to stimulate him. Soon his cock flared again, expanding at its tip as the lustful stallion was about to orgasm once more. But to my surprise, Iron Lance pulled me off him as soon as another burst of precum splurged from his tip, undoubtedly trying to prolong his enjoyment.

“On your fours, bitch!” he barked as he pushed me onto my hands and knees. “I want to blow my last load into that filthy slave cunt of yours.”

It was difficult to hide my glee at this point. I had the guard exactly where I wanted him, and completely oblivious of the fact that I was manipulating him into aiding me in my designs. The fact that I would be able to derive some physical pleasure out of it was just the icing on the cake. Happily obliging Iron Lance’s request I set my legs apart and I raised my tail, giving him a playful wink and squirt. It was all the encouragement he needed.

Roughly grabbing me by the mane, Iron Lance inserted his stallionhood into my sex once more. I let out a loud moan as he split my walls, hilting himself over and over again as he ravaged me like a feral beast. The doggy position was never one of my favorites - it always felt impersonal, less intimate than missionary sex - but this time I had no qualms being taken as such. I have to admit I took great satisfaction out of it though. I do not know if it was the aphrodisiac, the circumstance or the position I was in, but by the Sun his cock felt good! It rubbed me in all the right places, and it wasn’t long before I felt myself shaking with gratification once again.

Iron Lance was clearly experiencing similar pleasure himself. Soon he reached over, copping a good feel of my breasts as he grunted loudly, clearly unable to stave off cumming for much longer. The look on his face as he leaned over was one of raw ecstasy, mixed with a desperate effort to contain himself. I had the unsuspecting stallion cornered; grinding my rear back onto his member was all it took to push him over the edge. With a loud moan he emptied his balls inside me, gasping and panting as his cock throbbed with each injection of sperm, filling me up to the brim. The feeling was one of complete victory - Iron Lance had fallen for my ploy hook, line and sinker. I let the guard ride out his orgasm completely, knowing that he was close to crashing.

Finally Iron Lance’s cock went flaccid, slipping out of me as the exhausted stallion collapsed. Cum spilled out of me as he slumped onto the floor, and soon fell into a deep slumber. Likewise, I was drenched in sweat and physically shattered. It was incredibly tempting to lie down alongside him; every part of my body screamed for rest. But I knew that if I were to shut my eyes even for a moment I would seriously jeopardize my escape - instead I forced myself to focus on my task through sheer force of will. Making my way over to the stallion’s discarded pants, I attempted to remove the keys from his belt, a task made considerably more difficult by my paw gloves. After a couple of fumbles I finally managed to slip them off with the use of my teeth, all the while keeping an eye on Iron Lance to make sure he wouldn’t catch me in the act. Holding the keys to my cell in my hands was exhilarating - for the first time in an eternity, freedom was within my grasp. My chance had finally come!

Spurred on by the taste of success, I raised myself up off the ground and stood up. My leg muscles immediately contracted. Violently. Rune magic immediately activated upon the extension of my legs through the accursed boots I had been forced to wear, designed to discourage me from walking on my hooves like a dignified pony. Painful cramps and involuntary contractions instantly wracked my body. I fell to the floor, somehow managing to stifle a howl of agony as I twisted and squirmed on the ground. At the same time, a crippling fear took hold of me; if Iron Lance noticed my struggles, my one chance to break out of this infernal prison would immediately be thwarted.

My heart pounded in my chest as I anxiously looked over, adrenalin now masking the effects of weariness. To my great relief the stallion remained unaware of the theft, snoring loudly as he lay on his back. My enchanted leg wear clearly posed a significant obstacle to my escape, and my thoughts turned to removing them somehow - unfortunately my gloves prevented the use of my fingers, meaning I lacked the dexterity to do so. I would have to abscond on my hands and knees. Although the notion of having to continue crawling was hateful, I was determined not to let this minor setback deter me. I took the key in my mouth, and after some awkward fumbling managed to slot it into the lock.

Turning the key and opening the heavy steel prison door was an incredible moment. After so many months of degrading and humiliating myself, I was finally reaping the fruit of my labors! Once more assuring myself that Iron Lance was vast asleep, I slipped out the door and gently closed it behind me. I had done it, I was out! For a moment I savored the taste of freedom and the sheer relief of my plan coming to fruition, but soon forced myself to focus on my goals, being acutely aware that the most difficult part of my plan was yet to come. To delay Iron Lance in sounding the alarm when he would wake up, I locked the cell door and disposed of the key in one of the many crevices that littered the gaol.

The dungeon hall was far from silent. Muffled groans and tortured mewling emanated from the various cell doors, intermingling with passionate moans from guards satiating themselves with their hapless victims. Over the rhythmic sounds of hips slapping against rumps I overheard mares drunken with lust, undoubtedly under the effects of potions and spells, screaming loudly as they came. Although I was aided by the cover of darkness, escaping would not be easy. My sister’s former guards had taken over the watch, meaning I could not afford to linger. For a moment I considered trying to find Luna and release her from the torment she must be enduring, before realizing that regrettably I was in no shape to help anypony. I could only crawl, and with my hands strapped into my gloves had no way of overpowering any guards confronting me. Furthermore, I had no idea where my sister was being kept, and delaying my escape would only increase the chance of being recaptured.

The guilt I felt due to leaving Luna behind was painful, but the sensible decision was clearly to press on without her. It was heartrending not to be able to free anypony, but I made a silent promise to return with arms and free those subjected to this horrible treatment. I took a deep breath, prayed for a bit of luck, and made my way down the hallway, sneaking my way past the many doors and up the stairs that would lead to the castle proper.
