A week has now passed since my last entry. During this time my appalling treatment has continued unabated, up until today. This morning, to my surprise, I wasn’t greeted by a throng of lusty stallions wanting to have their way with me. Instead, Orestes, who seems to have been elevated to the position of Captain of the Royal Guard, came to inform me that I was due for an audience with the “king”, and that I was to be made to look presentable. My arms were bound behind my back, after which I was taken to the fountain in the courtyard. 
There I was greeted by two mares who had formerly been my attendants, completely naked and collared in red. I was disappointed to see they had decided to collaborate rather than resist. They bathed me in the fountain, scrubbing my body in full view of the guards, who forced their enslaved mares to watch my fall from grace. Although the water was cold I was relieved to finally be allowed to clean myself, or rather, to be cleaned. My matted mane and tail were meticulously washed and combed, for which I was grateful despite the lack of comfort. 
Any hopes that the Caribou had somehow come to their senses were quickly extinguished however, when a bull brought in a golden bit, chain and anal beads. To my dismay I recognized them as my own regalia by the gems set in them; they had been melted down and recast into what the Caribou deem to be the only jewelry fitting for their slaves. 
Two guards pushed me onto my knees before the bull, who then forced the bit into my mouth. He secured it behind my the back of head before revealing a small box containing two golden rings and a rather large needle. I shrieked and struggled when I realized their purpose, but my captors pulled my shoulders firmly backwards to expose my chest. I could only watch in horror at my imminent disfigurement. The Caribou roughly grabbed my left breast, and pushed the cold metal of the needle through my nipple. I bit down on my gag as hard as I could to try and take my mind off the pain. The sadistic glee of my tormentor was plain to see, and he watched me intently - I refused to give him the pleasure of seeing me cry or scream.
Once both my breasts bore those demeaning symbols of slavery, the golden chain they had prepared for me was fitted to them, connecting the rings together. Their weight caused me significant discomfort. Adding to my distress, I was then shoved onto the floor. The wretched slaver roughly grabbed my tail, pulling it up at the base, and started inserting the beads into my exposed rear.
I must point out that I had never taken anything up my backside before my capture, since it is highly inappropriate for a princess to engage in such depraved love-making; as such, anal insertions cause me great distress, both physically and mentally. The Caribou were quick to catch on to this, and are keen to humiliate me in this fashion. It wouldn’t surprise me if this repulsive sex toy was designed specifically with that thought in mind.
The first bead was the smallest, and slid in with relative ease. However, within moments I became acutely aware it was infused with the Caribou’s hateful rune magic. It wasn’t long before I started to feel light-headed; the bead seemed to affect my mind, dulling my train of thought and making it harder to concentrate.
Approving of my state of confusion, the savage then pushed the second, slightly larger orb up my rear. I yelped at its insertion. In addition to the discomfort it caused, it seemed to increase the effects of the first bead. I struggled to compose myself but barely had time to refocus as the bull, satisfied that the enchantments had their intended effect, mercilessly forced the other even larger spheres inside me. 
I was left to squirm on the floor as the rune magic coursed through my body. For a moment I felt completely lost and helpless. It was horrible - every time I tried to make sense of my surroundings my brain seemed unable to form any coherent thoughts. In my state of disorientation my eyes were met by the smirking Caribou standing over me, commanding me to stand up. Unable to muster any conscious resistance, I struggled to my hooves. The surprise I felt in the back of my mind at my ease of compliance was just enough to snap me out of it and regain my composure, although it required great mental effort to suppress the effects of the spell.
Orestes then fitted my bit with reins, and paraded me in front of a gallery of guards and stallions who had assembled to catch a glimpse of their former princess. Although I felt their piercing gazes while they shouted their obscenities at me, I refused to bow my head in shame and carried myself with the dignity expected of a princess of Equestria. I bore my chains proudly; they will see who has the last laugh. The large orbs inserted into my behind made it difficult to maintain a normal gait however, and I was led into the castle in this humiliating fashion.
The sight of my throne room enraged me. All the beautiful tapestries my sister and I had decorated the room with had been pulled down; the statues celebrating Equestrian values and liberties lay shattered on the floor, and the stained glass windows were in the process of being replaced with the Caribou’s perverted imagery, several featuring me personally. 
But perhaps most insultingly, my throne had been replaced with a seat of their own, inscribed with their runic script and displaying the severed horns of Luna, Cadance and myself. Rather ominously a space had seemingly been reserved for a fourth horn, meaning they could be aware that one princess remains free from their clutches and at large.
It hurt me deeply to see so many familiar faces present at the audience, although I did refused to show it. Many had been loyal courtiers and prominent Equestrians, but were now enslaving their fellow citizens to indulge in their depraved lusts - traitors to the crown, who I will see prosecuted once my sister and I regain power. Amongst the Caribou I saw several prominent males surrounding the throne, looking at me with the disdain they seem to have for all mares; in center sat the usurper, Dainn.
I would have screamed at him if I could. Struck him, spat in his face. Confronted him about the barbarity of his culture, and the disgusting treatment of ponies who should by all rights enjoy the freedom and equality that is their birthright. But whether by foresight or coincidence, my captors had denied me these options by restraining me. Instead of giving Dainn the pleasure of seeing me snarl at him impotently, I shot him a deathly glare. Dainn, seemingly unimpressed, returned a keen gaze, running his eyes up and down my body as if he was appraising his prize.
I was dragged in front of the throne, forced on my knees and made to bow before him. At length he spoke, declaring himself the new king of Equestria whereas I was now to be considered his possession. Placing his hoof on my neck to dominate and humiliate me, he stripped me of my status as princess and made me his personal sex slave. I am now a mere “cunt”, as they call it. The epithet fills me with disgust, and is yet another one of their uncouth and denigrating ways to describe a mare valued only for her ability to pleasure a male.
Then, right in the sanctity of my own palace and in front of his followers, he defiled me. The feeling of his member penetrating my sanctity was more gut-wrenching and disgusting than all of the others I had been made to service before. And to add insult to injury it felt...pleasurable. My body was clearly experiencing the residual effects of that accursed arousal spell - under no normal circumstance would I have taken enjoyment out of being violated by such a revolting brute. But the most vexing of it all was my own powerlessness - had I still had my horn I would have incinerated this false king and his lackeys on the spot! 
Instead I could only close my eyes tightly, trying to mentally isolate myself from the forced pleasure my body was experiencing as the wretch whispered into my ear how I was now his; how he would break me, turn me into a submissive whore; how I would one day worship his manhood and love it above all else. 
But no matter how hard I tried to resist it, every thrust of his vile member brought me closer to the edge. I felt him increase his rhythm and intensity in response to my involuntary moans, until I could fight it no longer. A powerful orgasm rippled through my body, as intense as anything I have ever felt. My vision went blank as my body convulsed, but when I regained my senses I was immediately filled with anger, regret and disgust - at myself, for allowing such a repugnant man to get me to climax. 
My insulting ordeal continued unabated however, and after what seemed like an eternity Dainn finally finished to the loud cheering of the crowd. The sensation of his pulsating manhood filling me up was one of sheer revulsion. I fought back tears of despair as he hilted himself over and over, releasing his disgusting seed inside me. It made me feel filthy, and it was a relief to feel him withdraw himself at last. 
As I lay writhing on the floor I saw Cadance kneeling before Dainn, happily lapping away at his softening member as it slowly withdrew into its sheath. When she was finished, or he just had enough of it, he roughly pushed her out of his way before returning to his seat. Her happy squeal and subservient tone when she thanked him is something I will never understand.
It was then that my minders restrained me again, pushing my upper body down onto the carpet while they pulled my rear up by my tail. Cadance clearly understood this cue, crawling over as I vainly struggled against the guards’ grip. They spread my legs apart, presenting my nethers to my niece, who without hesitation buried her muzzle straight into my most intimate parts.
Where Cadance learned these highly inappropriate skills I do not know, but I must begrudgingly admit she...pleasured me expertly. I caught my traitorous hips pushing back against the pressure of her tongue as she worked my sensitive folds and pleasure nub, eagerly drinking down what remained of Dainn’s essence. Although I struggled to maintain what little dignity I had left, to the delight of the crowd I could not prevent the occasional moan from escaping my lips - it wasn’t long before I was brought to another powerful, shuddering climax.
The “king” meanwhile, revealed the fate he had chosen for me - as his slave, I am to be turned into his sex pet, an animal to satisfy his depraved desires. A more humiliating station in life I cannot imagine; I am royalty, and this usurper will never see me willingly crawl at his side like a mere beast! 
Dainn then called on a Caribou called Anvari, seemingly a close confidante of his, with whom I am to begin what they call “training” to become the perfect sex slave they want me to be. I met his stern gaze with as defiant a look as I could muster, before he ordered my minders to take me away to be rested for the start of my reeducation, as he called it.
I look to the coming days with trepidation, but am confident that I can withstand whatever they throw at me. If they think they can break me, they are sorely mistaken. I will never accept slavery nor wear a red collar as long as I live!
