“M-master if I may?” Twilight whispered hesitantly, looking up at the dominant mare in confusion.
Luna nodded. “You may speak freely, my pet.”
The mare blushed lightly, a hoof going to her neck where her new collar and symbol of her submission now stood proudly. “Why are we going down into the dungeons exactly? Is there a prisoner that needs to be interrogated?”
“In a manner of speaking.” Luna remarked cryptically.
Twilight blinked, looking to Celestia for help, only to get none, as the submissive mare remained silent, walking beside Luna with her head lowered in supplication.
The dark alicorn strode confidently through the hall, followed closely by her pets, one of whom became increasingly confused and nervous as time passed. Twilight couldn't help but chew on her lip and shuffle awkwardly every time they stopped at a checkpoint and she frequently looked around, trying to figure out what was going on. From what she had seen they were obviously deep in the dungeons, but she had never been in this area before and knew nothing about it.
It was a good distance from the other cells, far from the squalor and discomfort that came with the small cramped rooms where temporary prisoners were kept. Over time the bars disappeared, replaced by doors with little more than peep holes in them, then that too was gone. Twilight could tell they were still in the dungeons proper, but most of the usual things you would usually see in a dungeon were simply gone. The doors were lavish with only a small, unassuming lock in the corner to indicate that this was anything other then another room. It was so different from the rest of the dungeon that unless you knew what area of the castle you were in it would be easy to mistake them as some random room with the lock on backwards.
Turning down a side passage, Luna nodded briefly to a guard who grinned and nodded back. He obviously knew better then to stare at the princesses’ pets, but it was also obvious that he was physically struggling to do so, earning him a sharp glance from the dark princess, who smirked when he gulped, and used a hoof to move his head towards the hall once more.
Together the trio made their way to the end of the hall, and towards a rather large cell that stood away from the rest. It had no easy method of looking within, and the door to the cell itself was thick and obviously reinforced by some form of potent magic. As they neared the massive wood and metal gateway Luna lit her horn and summoned a ring of keys.
From that ring she plucked one at random before pushing it into the lock and turning, revealing something Twilight didn't expect.
Nothing.
The room was empty save for a large bed devoid of covers or pillows in the corner of the room. Beside it was a simple toilet and sink and beside that was a wall absolutely covered in various bdsm toys ranging from simple riding crops to entire faux leather outfits. One of which seemed to be specifically sized for the young unicorn, and was complete with her cutie mark emblazoned on the side.
Twilight blushed, looking around the room slowly, taking in the sights of the many toys and gear that littered the room seemingly at random. As the unicorn wondered what the meaning of the strange room was, she noticed Celestia had taken a step ahead of them, seemingly taking stock of the room.
“It seems as though everything is as you desired master.” Celestia announced humbly, bowing her head.
“So it seems.” Luna commented dryly, giving the room only a cursory glance. “Is this all you think we would require?”
Celestia paused. “I think so, master. If there is anything else we require I will request it during mealtimes.”
“Good.” Luna turned to her newest pet and smiled. “Welcome to your temporary home. Here my other pet shall train you in what is expected of you as well as give you the necessary skills to serve me without embarrassment.”
Twilight blinked, only to remember her new place and bow her head. “Yes master. How long will I be staying here?”
“However long it takes.” Luna chuckled, turning to the door. “Though it will hopefully not take more then two days. If it does I will be… disappointed.”
Twilight gulped, ducking into an even deeper bow. “I will not disappoint you.”
“See to it that you do not. I will not be kind if I have to go without my pets for longer then a few days.” With that said, she turned and left, closing and locking the door behind her.
Now alone with Celestia, Twilight sighed and looked up to the alicorn. “So, uh. What exactly will we be doing?”
“Just as our master said. I will take over your training until such time that you are an acceptable pet.” Celestia remarked before smiling and nuzzling the smaller pony. “Oh Twilight I’m so happy you chose to serve master Luna.” She blushed, taking a step back and rubbing the back of her neck. “I admit being her only broodmare has become rather difficult over the past few weeks.”
Twilight blushed as well, remembering well just how large her new master was as well as the considerable amount of cum she could produce. “I am glad I can help.”
Celestia chuckled, giving her former student one last brief nuzzle before standing tall. “For the rest of the time spent in this room you will treat me as you would treat master Luna. Is that understood?”
“Okay.” Twilight replied simply.
A harsh crack suddenly filled the room and Twilight yelped, grabbing her throbbing flank and recoiling from the riding crop that had just struck her. “That is not the proper way to speak to master Luna, slave.” Celestia commented wryly.
Twilight recoiled, pulling her hooves from her aching flank and forcing her head down towards the floor. “Yes master Luna. My apologies master Luna.”
“Good.” Celestia stated evenly. “Now. Retrieve your uniform from the wall.” The alicorn pointed to the leather clad outfit that Twilight had noticed earlier.
“Right away master.” Twilight remarked, keeping her eyes low and her head down.
The unicorn trotted over to the wall and used her magic to retrieve the outfit, only to realize just how racy it truly was. It would show everything, and not only that it would also frame her more delicate bits with lines of black faux leather that drew attention up her legs to said delicate bits. Twilight tried to push those thoughts away, reminding herself that her new ‘master’ was right behind her, waiting.
Placing the outfit on the ground she realized something important.
She had no idea how to put it on.
Sure she tried, sticking her leg in one spot before taking it back out and trying again but that didn't seem to really get anywhere. She tried a few different ways, turning the entire thing upside down, left, right and finally when she managed to tangle her entire body in the outfit she gave up, laying in a heap of her own accidental making.
“Help.” She whispered, looking up at a smirking Celestia.
The alicorn shook her head, barely holding back the urge to snicker at Twilight’s ineptitude. “I should have known better. How many sets of clothes do you even own anyway?”
“Counting all my hoofy pajamas?” Twilight asked nervously.
“Not counting all your hoofy pajamas.” Celestia answered.
Twilight withered. “Two. Both are dresses Rarity made for me. They also may have come with written instructions.”
Celestia ran a hoof down her face and sighed. “This is going to take awhile.”
A surprisingly long time later and Twilight stood in the centre of the room, slowly stretching this way and that as she did her best to look at her new outfit. “Wow, this is really comfortable.” Twilight pointed out.
“Of course. Master Luna loves us after all.” Celestia remarked. “And we are going to have to spend a long time in them, so it makes sense that she would put in a little extra.”
Twilight blushed a little, her thoughts returning to the domineering alicorn. “I suppose that makes sense.” She shook her head. “Now what?”
Celestia walked behind the mare, gripping her tail tight in her magic. “Now we make move on to the next part of your little makeover.”
The unicorn remained stock still, trying to ignore how hot it felt to have her tail pulled and handled so roughly. As time passed her curiosity got the better of her and she looked back to find that her tail had been tightly braided with a dark blue peice of fabric woven throughout. It looked… nice, and it was another physical reminder of just who owned her, reminding everyone that gazed upon her now quite exposed mare bits, that she was owned by none other than princess Luna herself.
Twilight tried not to think about the fact that she was now basically presenting herself to anyone that walked behind her, and that her tail was no longer much help in this regard. “Do I have to wear this all the time?”
Celestia nodded. “Of course. It is a pet’s duty to be accessible at all times of the day. Your body is no longer yours. It is masters Luna’s. Plus, she enjoys being able to show us off.” The alicorn giggled at Twilight’s discomfort.
“I err… Okay.” She gulped, giving her body one last once over before reluctantly smiling. “It is kind of nice. It makes me feel really sexy.”
“I know right?” Celestia giggled, only to catch herself and cough. “I mean, of course it is. Master Luna wishes only the best for her pets after all.”
“Alright.” Twilight looked up at Celestia only to catch herself and look down, assuming a more submissive stance. “Now what, master?”
“Excellent, now it is time for the last part of your uniform.” Celestia smiled, making her way over to the wall where she retreived two toys.
One was a relatively large plug, easily large enough to fill the young unicorn’s ass further then it had ever been filled before. The other was massive, a towering pillar of plastic that on first glance was modeled after the peak stallion, only for Twilight to quickly realize it wasn't modeled after a stallion at all.
“Is that…?” Twilight whispered, staring intently at the mountain of fake mare meat.
“It is slightly smaller than our masters’ but other then that it is a near perfect replica.” Celestia sighed happily, running her hoof down the surface of the toy several times while smiling. “It has every ridge, bulge and vein that our master’s perfect cock has.”
Twilight couldn't help but lick her lips at the sight, entranced by the shear size of the monstrous horse cock. “It's immaculate.” She remarked.
Celestia nodded, only to realize how much time they were wasting. “Now then, turn and present.”
Twilight blinked only to quickly turn around. “Yes master.” She spread her legs and lifted her tail, an act that was mostly symbolic as it wasn't like the braided hair could truly obscure her nethers.
Celestia frowned, tsking to herself. “You need more emphasis on these muscles here.” Celestia ran her hoof across the lower parts of Twilight’s flanks.
“Like this?” Twilight shifted, trying to lift her butt and achieve what Celestia wanted her to.
The alicorn sighed. “Here, watch me.”
Celestia turned and presented, lifting her ass and spreading her pussy without so much as lighting her horn or lifting a hoof. Her entire body seemed to open up, as if the alicorn was not only presenting her nether regions but her very body in it's entirety, offering it to any who viewed her. Twilight blinked, only to realize that she was staring at her former teacher’s pussy.
The unicorn looked away hastily. “I think I got it.”
“I will be the judge of that.” Celestia remarked, standing tall once more and looking down at the unicorn. “Try again.”
Many tries later and Twilight stood proudly, convinced she had managed it this time. “Like this, master?”
Celestia hummed and hawed, prodding the other mare in a few places before nodding to herself. “Good work pet. Now hold still, this may be a bit… strange at first.”
Twilight held the pose, biting her lip and waiting for whatever was coming.
The first thing she felt was the lube slick head of the plug as it pressed against her asshole, forcing the unicorn to stifle a moan while remaining at attention. Thankfully it didn't take much force to fit the plug inside her, and with only a single firm shove, it slid completely inside her, filling her ass in it's entirely. “Now what?” Twilight asked, looking over her shoulder.
Celestia chuckled. “Oh that's not it. Don't move.” The alicorn gripped the plastic horse cock in both hooves and angled it towards the unicorn’s dripping sex. “If you feel as though your entire body is stuffed full of cock, that's normal and you should probably get used to this feeling.”
Twilight bit her lip a little harder, watching as Celestia gently slid the head of the fake cock against her snatch, lubricating the toy in the mare’s juices. It was surprisingly warm, and twilight found herself becoming more and more impatient as time passed. Celestia smirked as she noticed Twilight growing frustrated, her hips nearly vibrating, the urge to push back on the cock all but overwhelming her.
“Do you want it little slut?” Celestia asked, rubbing the cock head up and down the other mare’s snatch in a slow languid motion.
“I do master.” Twilight replied respectfully.
“And what if I said I was just going to sit here, teasing you for several more minutes?” Celestia raised an eyebrow. “What would you do then?”
“I would…” Twilight bit her lip and bowed her head. “Remain motionless as you instructed, until such time that you commanded otherwise of me.”
“Good pet.” Celestia purred. “As a reward for your good behavior I will not tease you even a moment longer.”
Twilight shuddered as he felt the thick head of her masters ‘cock’ enter her. The plastic head shoving aside the meagre resistance her pussy put up, slowly filling her snatch with what felt like a nearly endless supply of hard cock. The young mare had never had something so large inside her before, and coupled with the fact that her asshole was stuffed full, it made for an incredibly slow go of it, the mare’s pussy clamping down on the plastic cock like a vice. Even still, Twilight didn't cry out, her only sound being a small, muffled whimper that slipped past the hoof she was biting down on.
It didn't even seem to matter that she had been leaking like a faucet until now, the toy was simply so large, and her hole a virgin to all but the smallest of toys. It made for very slow going, to the point that Celestia began to frown, eying Twilight with confusion. “Twilight have you ever had a coltfriend before?”
The unicorn shook her head and sighed. “No master. I mean I have master. Only that he never really got this far before.”
“How far did you two go?” Celestia asked, all while continuing to stuff the younger mare’s pussy with the thick cock.
“Err.” The mare grunted, trying desperately to keep her stance open and her pussy spread while under such a powerful assault. “Second base?”
Celestia sighed, struggling to push the toy in any further. “This is going to take awhile.”
Several hours later a rather exhausted Twilight lay in a slowly gathering pool of sweat and bodily fluids, a triumphant smile on her face. “I got it!” She cried, raising a hoof in the air as she held the toy in her pussy with a hoof.
Celestia woke with a start, nearly falling off the small bed. “Whuh?” She muttered, looking around. Realizing what was happening the alicorn stood up and looked down at the unicorn, a smile on her face. “Congratulations Twilight. How long did it take?”
“Two and a half hours, give or take ten or twenty minutes.” She forced her smile to straighten and she looked up at the alicorn proudly. “That's good right?”
Celestia sighed, grabbed a second replica horse cock and roughly shoved it up her snatch in a single fluid motion, a motion which hardly seemed to take any amount of force at all. Twilight stood there in shock, amazed by what she saw. Celestia’s stomach bulged slightly, the small indent of the fake plastic cock still visible against the mare’s belly.
She looked down at her own stomach where the same sized toy made a massive bulge in her stomach. It stuck out nearly an inch from her belly, the unicorn having to magically restructure her organs to ensure she could even take it all without hurting herself. “Aww fiddlesticks.” Twilight cursed.
Celestia chuckled and pulled the toy from her pussy, an act that she accomplished using only her kegel muscles, with her hooves only entering the equation in order to catch the toy when it slipped completely from her pussy. With deft hooves she placed the toy back on the wall and walked over to a rather despondent Twilight.
“I’m not good enough.” She stated, staring down at the floor, tears building at the edge of her eyes.
“You are good enough.” Celestia remarked, kneeling next to the mare and wiping the tears from her eyes. “The master chose you, accepted you. Even knowing you were much smaller, and far less experienced, she took you as her own.”
The alicorn smiled, picking up the other mare’s chin. “You are a fast learner Twilight. I know you will not let our master down.” She winked. “Besides, you have the best teacher ever.”
Twilight nodded. “Your right. I can do this, I just have to focus.” She lifted her hooves up in triumph, only to accidentally release the hold she had on the toy inside her, causing it to fly out at what felt like mach two. “Aww fiddlesticks.”
Celestia chuckled. “Don't worry Twilight. I have a few tricks you might find useful.”
“Okay. But first do you mind if I got a hand standing up?” Twilight winced, rubbing the back of her neck awkwardly. “I don't think I can feel my back legs.”
The alicorn sighed. “I can already tell this is going to be a long night”
“Keep your legs together.” Celestia snapped, smacking Twilight’s exposed and already red rump with her riding crop. “Chin down, and keep your steps even.”
Twilight grunted, doing as she was told as she struggled to keep walking in firm, even steps. “Yes master, sorry master.”
The mare trotted around the room in a slow, even pace, the toys filling her other holes fighting to grab her attention. They were thick, and filled her in such a way that it made even walking hard. They had actually had to use a little more magic in order to alter her bones to ensure she could even take the entirety of Luna’s shaft, and even though the toy wasn't as big as the real thing Twilight still felt like she was little more than a cock sock.
It was like her entire body was becoming more and more of a receptacle for her masteres’ lust with each alteration she underwent. Not like that was a bad thing, in fact Twilight enjoyed this so much that she almost wished there would be another excuse to use more alteration magic. With each change she edged ever closer to the perfect version of herself, to the Twilight Sparkle that Luna would be proud to own.
The unicorn tried to focus on the fact that she was slowly but surely making Celestia, and by extension, Luna, proud. She smiled despite the circumstances, the pain in her flanks slowly fading away as she felt her steps become more and more confident.
“Now your getting it.” Celestia commented, watching closely as Twilight made two more slow circuits of the room. “Excellent work Twilight.”
The unicorn beamed proudly, while still keeping her head low in supplication. “Thank you master. You are too kind.”
Celestia nodded slowly, and lit her horn, allowing the small slip beneath the door to open. A large tray of food was subsequently slipped under, followed by a simple note. Picking up said note, Celestia blinked, smiling faintly before turning it over and handing it to Twilight. “Here. The bottom part is for you.”
Twilight nodded, grabbing the note and instantly noticing the flowing script of Luna’s hoof writing. Greetings, pet. I have been watching you closely over the last hour and must say I’m quite proud of what I’ve seen. You've learned quickly, as I knew you would. I look forward to seeing you soon in order to give you a proper reward. Your master, Luna.
“Oh wow.” Twilight muttered, clutching the note tightly to her chest.
Celestia smiled and gently ran a hoof down the younger mare’s cheek. “She is quite something isn't she?”
The young unicorn sighed contently. “That she is.” Reluctantly, Twilight placed the note back down and looked up at Celestia. “Does that conclude our lessons for now?”
“Indeed. Supper is served, after which we will rest and pick back up in the morning.” Celestia turned only to face hoof. “Oh yes and as long as we are not in a lesson do not treat me as you would the master. Obviously.”
Twilight nodded. “Of course.”
She walked over to the door and looked down at the considerable spread of food. Several sandwiches sat piled high on a plate next to what she assumed was cake, only it had so many different kinds of chocolate on it that she wasn't even sure it could still even be called a cake at all. “Wow, that's sure something.” She remarked, noticing how there were several other incredibly sugary treats next to a veritable shmorgesboard of food.
Celestia smiled and picked up an eclair before biting it in half, chewing happily. “Mistress enjoys her pets with a little more weight on them.” The alicorn gestured to the spread. “Go on, half of this is yours.”
“I er.” Twilight blinked, actually wondering if she even had the stomach space for all that food. Only to quickly remember that this was sent by Luna, the mare that had captured her heart and now owned her body. “I’ll get right on that.”
Celestia smiled and placed a hoof on Twilight’s shoulder as she moved to sit. “I wouldn't do that if I were you. You don't have the training necessary. And I fear if you sit all the way down you won't get back up.”
“What do you…” Twilight blinked, only now remembering that she had two enormous toys still stuffed up holes. The mare blushed hard, standing fully once more. “Right.”
Celestia chuckled. “Well we better hurry up, we have a long day ahead of us.”
Twilight shuddered, her mind already wondering what could possibly be on tomorrow's schedule considering what they had all covered over the course of a single day. “I can hardly wait.”
The next day was a strange one, filled with more lessons on etiquette than Twilight had ever even heard of existing. Though even then most of them were centred around one thing and one thing only, serving her new master. It included things like how to refer to her new master, what honorifics to use, what body language was acceptable. The list went on and on.
By the middle of the day Twilight felt as though her entire world had been turned upside down.
Everything she had assumed was correct had been thrown out the window, and yet she persevered.
Her arousal seemed to ebb and flow, and by the time the afternoon meal came by Twilight felt as though she had finally gotten used to the feeling of having the toys inside her at all times. It had helped that she had slept with them inside her, stretching and warping her body during the hours she lay cuddled next to Celestia.
It had been a hard lesson, but the thought of Luna’s smiling face and proud words helped her to stick it out in the end. Plus Celestia was a great teacher, helping her learn at a rapid pace while encouraging her and recounting the many pleasures of serving under such a magnanimous mare like Luna.
Now she stood, her butt raised and a smile on her face. “I’m ready master.” She announced happily.
Celestia nodded. “Remember what I said. The key is to be just as tight as you need to be, but no more.”
Twilight nodded. “I remember master.”
“Good.”
The alicorn gripped the toy that had been magically sealed within Twilight’s pussy for over twenty four hours. Dispelling the charm that kept it in place was the easy part, what came next would test the young unicorn’s newfound skills considerably. With a slight tug, Celestia pulled back, judging just how tight Twilight was by how easily the toy slipped out.
It was smooth, neither nalting nor too slow, just as she knew Luna liked. With a slow tug of her magic Celestia pulled the massive toy from Twilight’s depths, the bulge in her midsection slowly vanishing.
The unicorn herself was awash with emotion.
On the one hoof she was nearing her graduation, on the other hoof the loss of the toy felt like losing a leg at this point. The feeling of fullness had become so synonymous with her existence that it's loss was a keen one and she struggled to maintain a more or less neutral expression as she felt it leave her. With a final tug, the toy popped out of Twilight’s well used pussy, which hung open, gaping slightly as it struggled to shrink to it's normal size.
“That was pretty good, a little tight at the end there but overall was quite exceptional.” Celestia remarked.
Twilight sighed. “Does the emptiness ever go away master? It is quite… disconcerting.”
The alicorn chuckled. “Unfortunately that part doesn't go away. It is an important part of making a good pet as it means you will always be ready for the master’s attention.”
The unicorn shifted from hoof to hoof awkwardly until she finally forced herself to stay still. “What is next, my master?”
“Let's see.” Celestia picked up a list and began to go down it, stroking off everything they had done. “Etiquette, check. Stretch training, check.” The alicorn muttered to herself, going down the list until she had checked off nearly everything. “I think we just have some more leash training and that's it.” She frowned, tapping the paper a few times. “Though I still want to go over your felatio training a little more. Master primarily enjoys it when we pleasure her stallionhood but occasionally she will indulge in pleasuring her other sex.”
Twilight nodded her head dutifully. “Yes, my master.”
“And…” She paused, looking up to the door suddenly.
Twilight turned as well, only to immediately duck into a deep bow. “Good evening master.”
Luna smiled down at her bowing pets, noticing how they both perfectly bent themselves in supplication, their noses nearly touching the ground as their back ends stayed in the air. “Good evening to you, my pets. You may rise.”
Celestia and Twilight both did just that, waiting patiently for orders from their master. Luna looked around the room, and upon noticing the checklist, walked over to it and began to read in silence. “Ahh, so training is complete then?”
Celestia glanced to Twilight briefly, deep in thought for a moment before nodding. “She has some minor lessons yet to learn, but they are just that, minor.”
“Good.” Luna smiled, slowly circling the much smaller unicorn and watching as she stood perfectly still, unmoving under the intense focus of her master. “Do you feel as though you are ready, my pet?”
Twilight hesitated a moment, only to clench her jaw and force away the lingering doubt that threatened to cloud her mind. “Yes, I believe as though I am ready, my master.”
“That is rather bold of you.” Luna remarked, running a hoof down Twilight’s side, starting from her neck and ending at her flank, where she gave a teasing slap, and noting the way the unicorn seemed to shiver from the mere touch. “Very well. You will be joining me tonight for the the ceremony.”
“Ceremony, master?” Twilight asked hesitantly, glancing to Celestia for help only to notice that the leather clad mare was grinning from ear to ear, not paying her any attention.
“Oh master that is wonderful news.” The white alicorn remarked. “I am assuming all went according to plan then?”
Luna nodded, trotting over to Celestia and cupping the mare’s chin. An act that made the white alicorn’s cheeks alight with color and send a shiver down her spine. “It went perfectly. Everypony was able to make it, and all the decorations you planned look amazing.”
Celestia shuddered as her smile grew to the point that it encompassed nearly her entire face. “Thank you master. I am delighted to be of service to you.”
Luna smiled back, pulling her hoof down and taking a step back. “I am glad to hear everything is going according to plan. Though I had initially planned on giving you a test of your abilities, and what you have learned, we are running close to the deadline.” The mare turned and smiled down at the unicorn, who looked up at her nervously, barely able to suppress the urge to squeal giddily. “Do you think you can handle the weight of your duties, my pet?”
“Absolutely master.” Twilight replied confidently, the many tests and lessons Celestia had helped her to endure flashing through her mind.
The white alicorn gave her a sidelong glance, unease evident in her expression. “Are you sure she is ready for this master? She has done well but…”
Luna nodded. “She is ready. Ponies will be arriving soon, and tonight is the perfect night for such a ritual.”
“What kind of ritual are you talking about master?” Twilight asked hesitantly.
“You will see.” Luna remarked cryptically before turning and walking out the door
“Okay then.” Twilight frowned, putting her head down and following close behind her master, shooting Celestia a pleading look.
The alicorn merely sighed and shook her head, indicating she was not allowed to give up the secret before Luna revealed it in grand fashion. As they walked Twilight couldn't help but wonder what it was, and what it might mean for her. She was surprised to find that she grew hotter and hotter the longer they walked, the screaming emptiness between her legs making it difficult to think. In the end she gave up the line of thought, concluding that it had to be something that involved her get fucked like the worthless slut she was.
It was the only possibility that both made sense, and ended with her finally get the void between her legs filled.
Twilight glanced out the nearby window, noticing how the sun was sinking in the sky, entering the time of day that she was named after. All around her she noticed guards and seemingly random ponies running this way and that. Though there was a small part of her that felt embarrassed by the stares her new dress garnered, her training with Celestia ensured she didn't give them much mind.
The only eyes that matter belong to the master, she is the only pony whose opinions matter. Celestia’s words came unbidden to Twilight’s mind, prompting her to stand a little taller, while still ensuring her head was lowered differentially to her master.
The mare felt her lips curl and she flashed a brief glance up to Luna who was speaking animatedly with an assistant Twilight had never seen before. From what she had gathered, the ritual that Luna had spoken of was some sort of event, one that needed, what looked like, the entire population of Ponyville to be present for.
Her smile slowly fell away, and she began to wonder if that was what in fact Luna had in mind, as Twilight had seen many familiar faces while walking the halls of the busy castle. Celestia had refused to fess up anymore information, though she did seem to grow steadily more excited as time passed. For a reason that only she and Luna could actually know, as the mare’s famous poker face was in full affect.
The mare kept her head down, having grown so used to the feeling of wearing the faux leather outfit that she didn't even notice it's presence anymore. Or at least she wouldn't have, if Luna hadn't clipped a leash to the front of her collar and was now leading her around. “Hold, pet.”
Twilight stopped instantly, keeping her gaze low, while grinning madly. “Is it time for this ritual you spoke of master?”
“It is indeed.” Luna remarked with a smirk. “You were leash trained, correct?”
Twilight nodded. “I was, master.”
“Good.” Luna turned and began to walk, holding Twilight’s leash tight in her grasp and keeping the unicorn a respectful distance away. “Two things. First, you will remember your place, and you training. Second, you will do exactly as I tell you, exactly when I tell you, your ability to speak is rescinded until such time that I expressly allow you otherwise. Understood?”
Twilight nodded.
“Good.” Luna’s trot seemed to become more confident and she strode down the hall, making Twilight struggle to keep up with her master’s longer legs.
Twilight blinked, looking out over the crowd that filled the audience hall to the absolute brim. The entire population of Ponyville filled the stands, as well as everyone she knew from Canterlot including her parents and even her old classmates. She looked up at Celestia, only to notice that the alicorn remained steadfast in her position, her head bowed in supplication and her expression calm and serene. Twilight wanted to speak, wanted to ask what they were doing up on a stage in front of everypony she had ever known, but her ability to speak had not been given back and she dare not interrupt Luna’s speech.
“-which brings us to this very momentous occasion!” Luna raised a hoof, uncaring to the eyes that were drawn down to her throbbing erection that bounced at her waist. “The harvest moon is an ancient tradition that I am happy to bring back this night. This will allow longer hours for farmers, as well as allow for safer travel during the night for the entirety of next week.”
Twilight nearly frowned, wondering why she had been brought up in front of all these ponies if that was the only point of Luna’s speech. She hoped it would end soon as something about having the eyes of all of her friends and even her parents, on her while she was wearing something so, risque was a strange one. It wasn't exactly annoyance or irritation or anything negative, as she had been taught to not care about such petty things, but it did make her feel odd. As if she was almost a little perplexed by the fact that this no longer bothered her overmuch.
“But before I raise the harvest moon and help to usher in an age of unmitigated prosperity, we have another matter to attend to first.” Luna announced, a hint of joy slipping into her voice as she clopped her hoof against the stage. “As you may know, I have taken two royal concubines, and tradition dictates that I enforce my will upon them in view of the public and their peers.”
Twilight’s eyes went wide and it took every lesson celestia had drilled into her over the last two days not to gasp or look up. She could only weekly glance at Celestia, who seemed to smirk knowingly, as if she had been privy to this information the entire time. The mare tried her best to push out the sound of the crowd whispering amongst themselves but it was a difficult task for the young unicorn.
“The ritual that binds a concubine to my will is eternal, and requires me to do something truly special.” Luna smiled as she gazed out across the crowd, noticing how a good majority of the crowd was either listening in rapt attention or was otherwise on the edge of their seats.
Sure there were a few hold outs but the spell Luna had placed on the room should slowly weed out those select few. She was especially happy to note that most of Twilight’s friends save Rainbow Dash and Applejack seemed to either be in agreement, or was otherwise visibly aroused by what she had just said. “This will also usher in an age of renewed sexual freedom for Equestria. Something that will begin upon this stage with the impregnation of my first concubine!” Luna grinned, turning to Celestia and raising a hoof. “Oh Tia, it is your turn to take the stage.”
Celestia nodded dutifully, inwardly hiding a massive smile that threatened to peak out around the edges of her neutral expression. Twilight meanwhile, was left to watch as Celestia walked to the centre of the stage only to turn and present her bare pussy and ass for the world to see. The ensuing silence was deafening and Twilight was sure she could hear a pin drop.
Then the alicorn turned and trotted next to Luna, bowing briefly before taking her assigned position. Luna nodded, whispering something in Celestia’s ear before trotting back and preparing to mount the white alicorn. Whatever she had whispered must have been good as the mare’s cheeks glowed and Twilight could tell just from the way she shifted her back legs that Celestia was very, very aroused.
Luna wasted no time, hoping up onto her sister’s haunches. “Now, kneel before your new master.” Luna commanded.
And Celestia obeyed, keeping her ass raised while simultaneously bowing so low that her chin touched the ground while her wings splayed, symbolically and literally opening herself to Luna. Something the dark alicorn seemed to take great joy in, smiling so wide that it split her face while her cock pulsed with need. After a moment of silence the alicorn lit her horn and touched it to the tip of Celestia’s, causing the alicorn to shudder, the light of Celestia’s horn changing from it's normal gold to the color of Luna’s own magic.
Before Twilight could even peice together what was happening, Luna raised her cock, and rammed herself into Celestia’s pussy with enough force to make the white alicorn’s hooves scrape against the floor. The unicorn’s jaw fell open, and her shock nearly made her forget her lessons, yet still things did not end there. The dark alicorn drew back her hips and thrust forward again and again, ruthlessly fucking her sister for all to see.
Twilight looked out into the crowd, shocked to hear that they remained relatively quiet. All eyes were on Celestia and Luna, most of which seemed to have some form of envy evident in their expression, stallions included. The young unicorn was baffled by the strange turn of events, especially when she noticed that both her parents and friends were now firmly in the camp that was staring intently at the coupling alicorns.
Her mom was biting her lip, a hoof between her legs, while her mom nervously glanced at her dad, his growing erection becoming difficult to ignore. Her friends weren't much better, with both Rarity and Pinkie Pie masterbating openly, one hoof in each other’s nethers, a smile on their lips. The rest of her friends seemed somewhat more subdued, but even then she could tell Rainbow Dash and Applejack were seconds from doing the same.
Time seemed to slow down, as everyone watched in rapt attention, their eyes never leaving Luna and Celestia while they fucked in full view of everyone. Time seemed to lose all meaning as twilight also found herself staring, here gaze drawn to the intense, jack hammer like thrusts that sent her teacher’s flanks quaking. Celestia moaned like a whore, uncaring or actively enjoying the attention she had garnered from being so vocal, while Luna remained stoic as always, hardly giving more than a grunt to indicate that she was even enjoying herself.
The only thing that existed in Twilight’s view was Luna’s titanic cock as it vanished into Celestia’s hole over and over again. When Twilight seemed to come to, she instantly noticed that her knees were shaking so bad she could hardly stand, and it felt as though she had just ran a marathon. She blinked rapidly, only now noticing just how dry her eyes had become, realizing that they weren't even quite done yet.
Celestia was moaning louder than ever, her wings twitching as her tongue lolled out of her mouth. Above her Luna even seemed to be giving voice to her lust finally and was grunting with every short, brutal thrust. This wasn't strange in itself, but by then Twilight had seen Luna finish enough times to know the signs.
Sure enough, it wasn't much longer before Luna’s hips stopped suddenly, as if freezing mid thrust. The young mare’s eyes found themselves drawn down to Luna’s massive balls, watching as they twitched and quivered, shooting a no doubt massive load deep into Celestia’s womb. Twilight watched each distinct bulge of cum as it traveled up her master’s shaft and into her former teacher’s body.
Within seconds she could see that Celestia’s body was already struggling to contain the titanic load, her belly stretching as she was forced to take more and more of her sister’s cum. Seconds ticked by, and as time passed, Twilight watched as Celestia’s expression morphed from one of lust, into one of pure joy.
“It is done.” Luna announced.
Celestia whimpered, her hooves shaking as she tried to push herself up and though it took a second she did indeed manage to stand, though even then it looked as though she may fall again at any moment. Luna took a step back, walking backwards as she extracted her cock from Celestia’s cloying depths. Yet despite the no doubt copious amount of cum now swirling inside Celestia’s pussy, none dripped out, indeed Luna’s cock seemed as though it were cleaned.
It was then that Twilight noticed a small shimmering wall of blue magic at the entrance to Celestia’s pussy, holding fast the load of cum that threatened to spill out. Twilight gulped, imagining the same applying to herself and finding that she was not only turned on by the idea but that she was even eying her fellow pet with a hint of envy.
She squashed this emotion quickly and bowed her head respectfully, waiting for Luna’s next action.
The dark alicorn took a final step back, before giving the alicorn a firm smack across the ass. “Stand, slave.” She commanded.
Celestia pushed herself the last of the way up, trying and nearly failing to bring her hooves completely under her. Now standing upright, Twilight could tell just how much cum had been deposited into her fellow pet, a realization that made her equal parts scared and envious.
“Stand over there.” Luna commanded, gesturing to the other side of the stage. “I have another pet to break in.”
The spell that bound the crowd seemed to break, and the various ponies found themselves shocked at just how fascinated they had become. The members of the audience didn't have much time to recover, as the second Luna spoke, their attention was then glued on a new target.
“Twilight Sparkle.” Luna spoke, gesturing to the unicorn, who nearly yelped in fright. “Please do as Celestia had, and present yourself before taking your place before me.”
Twilight nodded dutifully, stowing her fear and indecision deep within herself. “Yes master.”
The mare walked slowly, deliberately, taking her place at the front of the stage and passing by a grinning Celestia, who leaned close and whispered. “Relax, remember what I taught you.” Before slipping away, and taking her place where Twilight had just stood.
Twilight tried her best not show her worry, and succeeded only partially, her nervousness coming out in how she stopped and hesitated a moment. Knowing that the eyes of her master were upon her, Twilight did not hesitate long, before turning and displaying herself to the audience as Celestia had taught her to do. The subsequent knowledge that everyone was now staring at her privates was surprisingly not as terrifying as she thought it would have been. Her eyes had strayed upwards and caught a glimpse at an absolutely beaming Luna, who looked down upon Twilight with barely contained joy, giving Twilight all the strength she needed to power through what little embarrassment she still felt.
Turning away from the crowd Twilight strode confidently to her place in front of Luna before kneeling as Celestia had, taking her rightful place on the ground, her nose lowered in absolute submission to the one mare she craved above all others. “Excellent.” Luna whispered, running a hoof down Twilight’s back.
The mare shuddered in pleasure, surprressing a moan that threatened to break the relatively neutral mask she wore.
“Now we welcome the second, and last of the royal concubines, and future brood mare of my descendants.” Luna announced excitedly.
The crowd remained deathly silent, with only the odd whisper reminding Twilight that there was even anyone there at all. A second later she heard the subtle shift in weight as Luna leaned forward, her horn glowing bright enough that Twilight could see it from her current position. A second later she felt it, a connection that linked their magic and thus their will. The sensation seemed to shift, as Twilight’s own will was supplanted by something far more superior, and far more important.
Then it was over, and Twilight was left wondering what had even happened, though she quickly pushed these thoughts away, as she knew very well what was coming next. Sure enough, a second later she felt the head of Luna’s cock press against the entrance to her pussy. There the mare seemed to hesitate a moment before suddenly driving her hips forward and nearly lifting Twilight off the ground with the shear force of her thrust.
For a second Twilight’s world went dark, only for her new instincts to kick in and she felt herself grip the ground once more, stopping herself from skidding forward, and keeping her body in position. Regripping the ground with her hooves, Twilight caught herself completely before she had moved more than a few inches.
It was at this moment, while she was struggling to keep her legs under her, that she realized that she had taken it all. Her pussy was stuffed well beyond what should be possible, Luna’s inequine cock somehow managing to fit entirely inside Twilight’s too small pussy. Yet despite the alicorn’s truly titanic proportions, she had done it, the emptiness within her was fulfilled in it's entirely and then some.
Joy the likes of which Twilight never believed possible suddenly exploded in her brain and she was forced to fight off the nearly overwhelming urge to black out once more. Luna had not remained stationary though, and Twilight found herself rocked forward as the alicorn began to thrust in earnest, pounding Twilight’s pussy with all the force of a freight train.
Hold fast Twilight! The master is a relentless and passionate lover and she will not stop until she is satiated. Keep your forehooves apart and focus on merely standing before pleasuring her. Celestia’s voice rang out in Twilight’s head, a lesson only half remembered returning to her mind all of a sudden.
The young unicorn grit her teeth, holding fast to the stage and ensuring she did not slip forward any further. It took several long seconds, seconds that she nearly felt as though she might lose the fight against Luna’s powerful legs but then she felt it. Her hooves had a solid grip on the ground, one that did not feel as though it was going to vanish in a moment’s notice.
She then focused her attention on her master, squeezing and kneading with her inner muscles every time she felt Luna bottom out inside her. Instantly she noticed that Luna’s body grew more relaxed and her thrusts seemed to lose a little of their insistence. Noticing that she was finally getting somewhere, Twilight reminded herself to keep focus on her hooves first before then turning back to pleasuring her master.
Let your master know just how much you love her cock, moan her name, whimper like the whore you are, do anything to tell our master that you love her. Twilight grit her teeth, recalling another lesson.
The unicorn moaned aloud, at first no louder than a whisper, only to build over time as Luna continued to ruthlessly fuck the mare’s abused pussy. Her voice grew and grew until she was all but screaming her master’s name, not even thinking of the ponies in the audience that no doubt watched and heard her. Again Luna seemed to take note, her stance relaxing even more, and her own tiny grunts and moans becoming slightly louder.
Time seemed to blur once more, the young unicorn falling into a routine of squeezing, kneading and pleasuring Luna’s cock while ignoring the feeling of her stomach distending and bulging obscenely with every thrust of her master’s hips. Throughout it all, she held tight to her grip on the ground, ensuring she did not disappoint her master.
Which is something she achieved in spades, as Twilight could already feel the distinct churn of seed from Luna’s sack. Sensation seemed to return to the mare, and she quickly realized that a considerable amount of time had passed. Her pussy was nearly numb after being stretched and fucked so remorselessly, and her hips were growing sorer by the minute. Even her hooves were beginning to tire, and she could feel her joints cry out with every thrust of her master’s hips.
Yet she did not give up, she was close now and she refused to disappoint her master.
With one last thrust of Luna’s perfect hips, she felt it.
Cum the likes of which Twilight had not even believed possible began to explode inside her, filling her womb by the third shot and the rest of her pussy by the sixth. By the eighteenth Twilight was pretty sure most of her body was now little more then a receptacle for her master’s seed and her mind threatened to slip from her grasp once more.
But the young mare refused, gritting her teeth tightly and holding fast to the pleasure coursing through her, pleasure that came with the realization that she was now no doubt carrying her master’s foal. Or judging from just how much cum there was, several foals.
“Look, Twilight.” Luna whispered, running a hoof under the mare’s chin and drawing her eye up to her friends. “They are proud of you, they are all proud of you, but more importantly, I’m proud of you.”
Twilight Sparkle could feel tears at the edges of her eyes, and she was only dimly aware of the fact that her friends and family did indeed seem proud, smiling down on her with admiration in their eyes..
None of that mattered though, for Luna was proud of her.
Her master was proud of her.
