Royal Breeding

Celestia kept a lot of secrets.

She had to have, for the sake of her subjects. After all, with myriads of insane laws, dangerous spells and artifacts, and random favours passed in the many millennia of her life, who knows what would happen if the public were to find out about them?

But, she also kept some very personal secrets, moreso out of what the public would think of her if they knew about them than their own safety. Many of those were her fetishes and the material she used to satisfy them, such as how she absolutely loved being a sub, covered in loads of spunk, and spanked until her ass turned glowing crimson, but all of these were dwarfed by one in particular that was able to build for multiple millennia and would be deemed completely unacceptable by society; the lust for her sister.

And yes, it was lust, for everything about her sister drove her crazy- though not in public of course, for she had quite a lot of practice to control herself- from her dark complexion and her shy demeanor, to her archaic language and foalish glee she sometimes held, it all seemed incredibly arousing to the elder princess. However, she never expressed this lust to her, for how ever much she lusted after her sister, she loved her as well, and would certainly not wish things to be awkward for millennia to come by expressing her selfish sexual desires for her.

Recently though, she found her desires harder to control, and all for one reason: Nightmare Moon.

The destructive alter ego of Celestia’s dear sister showed a dominant side to her she never saw before, and made her all the more aroused by her. The heavy contrast the solar alicorn found in her sister’s states drove her mad with lust, and the only reason she didn’t act on it was because of Nightmare’s truly awesome violence, forcing her to keep a straight face (and dry panties) while she worked to stop her. It didn’t help that she had to send her off so far away and for so long, leaving the elder mare in sexual despair for a millennium.

So often she found herself at night masturbating intensely with her massive stash of sex toys and sex-based spells, imagining having some of the hottest sex that she could possibly think of with her sister’s dominant alter ego. It’s even worse that when she finally passed out from all the masturbation, her dreams were littered with her sister doing things her conscious mind could not even comprehend to her.

When Nightmare eventually came back, she found herself lucky to not have to fight her intensely, for her mind would have been easily sidetracked by the overwhelmingly dominant and sexy nature of the dark alicorn for her to be truly of any use. After she finally managed to get her true sister back, she was forced to accept she no longer had the possibility to engage with her alter ego, thus making her desires even worse.

So now, once again, Celestia found herself in one of her unfathomably lewd dreams, this time her body was chained to fencepost in the middle of Ponyville, all of her subjects from within the village, and many others from outside, gawking in awe and arousal while they listened to the speech Nightmare gave them about the usage of her sister as a public cum dumpster and sexual relief emporium, as all of the usually female subjects had a huge stallionhood in this mad dreamscape.

All of the subjects took turns, sometimes multiple at once, including that of the farm ponies, the spa ponies, the flower ponies, all the shopkeepers and homeowners, the barkeeps and fashion designers, shoved their huge cocks into her holes and absolutely rutted her, leaving her utterly senseless and absurdly inflated. All of the Elements of Harmony took turns as well; Rainbow Dash with her rapid flurry of thrusts, Applejack with her powerful bucks, Rarity with her sophistication and levitation, Pinkie being erratic and manic as always, Twilight taking a calculated approach with a large book by her side, and even sweet, demure Fluttershy went, though her shaft was ludicrously large, only second to Luna, but managed to fit despite the laws of geometry stating otherwise.

And of course, there was Nightmare Moon herself. She was the best of all of them, what with her gothic color scheme, her rather risque armour, her indescribably confident smirk, and let’s not forget her shaft. It was nearly the size of the rest of her body, the voluminous balls below nearly scraping the floor from the impossible amount of seed in them, and it was even worse that the liquid could be heard sloshing around inside them, further accentuating their immense sexuality.

The dark alicorn managed to shove her stallionhood into Celestia’s wrecked pussy which was frothing with the seed of her subjects, forcing a emotionless, yet lustful moan from the mare whose mind has been turned to mush. She went all the way in, mashing her hips to her sister’s ass and grabbing onto them before she started to thrust. Her movements were powerful, violently jostling the huge cum-balloon of a belly the solar pony had with each impact, quickly developing into a quick, yet forceful rhythm that left no room for her to regain her bearings.

The ministrations lasted for what felt like hardly any time to the white alicorn, as she could hardly hold onto any piece of the past, before her sister started pumping her already ungodly oversized belly with cum. Her size became immeasurable as she became even larger, her mind truly losing its sense of time as she basked in the sensations as well as she could, along with those that came when the monumental shaft was pulled out of her, letting liquid flood out of her pussy once more.

She eventually began to sense something other than the endless sea of pleasure she was subjected to, slowly sharpening her senses, to make out what sounded like a voice calling her name. When she finally managed to reign in her body, she found herself laying down on a glassy floor, deprived of any clothing as she looked around her and found herself in a sea of stars.

Realizing where she was, she looked around again and spotted her sister, who was draped in her traditional dim blue robes and had and unreadable expression on her face.

“Eh, hi Luna,” Celestia said, a heavy blush creeping up onto her cheeks. “I, uh, suppose you saw all of that?”

“That I did, sister,” Luna answered calmly, still looking to be processing what she saw.

The pair stood in an uncomfortable silence before the darker pony shook her head before saying, “Apologies for intruding upon thine privacy, dear sister, but We believe something may be amiss.”

The other alicorn got to her hooves and looked to her sister in concern while she asked, “And whatever would that be, Lulu?”

“We have not heard from Twilight Sparkle or Mi Amore Cadenza, despite Our numerous attempts to contact them. We are somewhat worried, even if it has been a mere day since were first asked for them, and We feel that such is too petty to disturb thee from thine slumber as of yet,” Luna explained. “We were hoping thou knew of our fellow princesses recent whereabouts, and thus determine if Our fears are unfounded or not.”

Celestia paused for a moment to think before replying, “I have not heard anything from either of them recently, Cadenza the past month or so, and Twilight a week at most. While they don’t have a great propensity for writing to us often, it is odd how they haven’t responded to us yet,” Her expression turned lightly concerned, “I suppose I am slightly worried as well.”

“So shall We wake thee and make for their locale posthaste to check upon them?”

“Perhaps not just yet, give them time to wake so that they may read and reply to any letters before we go for them; I’d rather we no declare an Equestrian crisis merely because our fellow princesses were tired.”

Luna nodded in understanding. “Of course,” She responded before her expression turned mischievous and she said, “Now, back to what thee were dreaming about.”

“Ah, well,” Celestia started, her blush returning full force while she looked away from her sister timidly. “I just-” She got cut off when the world around her suddenly shattered. “GAH!” The solar princess shouted as she awoke with a start, sitting up sharply.

She took a few moments to calm down from the adrenaline before looking around her, spotting vibrant, glowing greens in a midst of charcoal black, instantly alerting her to where she was. She tried to stand up, was was stopped by chains holding her wrists to the floor at around half a meter in length, causing her to look down at her body and notice the other pair around her lower legs. She also noticed that she was stark naked, yet it was hardly as much of an issue as her being held captive in a changeling cave, so she immediately attempted to focus magic into her horn, yet it fizzled partway up, signifying a magic dispersion ring on her, and thus rendered her completely captive.

Since she could make no attempt for escape, she looked around the cave to get a better idea as to her surroundings. She spotted the wealth of translucent green goop splatted across one side of the room, the strong scent of musk in the air, and the- was that-

“Twilight! Cadence!” Celestia called, seeing the other princesses laying face down on the ground several meters away from her, unconscious. “Girls! Wake up!” She shouted, yet still to no avail. “WAKE UP!” She yelled, using her seldom-used Royal Canterlot voice to amplify her volume, finally stirring the other mares.

“Mmh?” Twilight mumbled as she awoke, blinking several times to clear her eyes, while Cadence merely inhaled heavily before they both looked up and spotted each other. “Mm, hey Cady...” The lavender alicorn said groggily while she looked lovingly at the other mare.

“Hi, Twily,” The pink pony replied, then added, “I didn’t realize Chryssi loved you too...”

The former unicorn giggled drunkenly before responding, “Careful, we don’t want upset Mistress with our pet names.”

Celestia balked at the revelation of two of her fellow princesses being sexual slaves to the infamous Queen Chrysalis, while the other mares merely looked at each other lustfully before losing the gap between their muzzles and kissing passionately. They grasped the other’s heads with their hands and forced their tongues into each other’s mouths, loudly slurping as they tasted each other.

“G-girls?” The solar alicorn interrupted, getting the other princess’s attention and forcing them apart to look at her.

“Oh hey, ‘Tia~” Cadence said in a inebriated and sensual fashion while she and Twilight started to crawl over to the white princess.

“What... happened to you?” Celestia asked, still in utter disbelief, causing the other mares to pause their movements and look at her questioningly. “I-I mean... you’re acting so differently... and you say that you’re with Chrysalis... h-how?”

The lavender pony giggled before she responded, “Silly ‘Tia, we love her. I mean,” She glanced back at the pink-coated princess, “How could we not?”

“Yeah!” Cadence interjected. “She’s really nice to us; she feeds us and gives us her hospitality, she’s managed to reprieve us from out huge responsibilities as princesses, and she’s also really hot,” She added, getting a dreamy look in her eyes.

“Mm-hm!” Twilight nodded while biting her lip in lust. “Her exoskeleton looks really hard, but it’s actually super soft... Her entire body is so voluptuous with her big, plush ass and her massive, plump boobs.” She gasped softly while looking down at her nethers, just realizing that she subconsciously slid a hand down to her sex in her reverie. “But she’s also got really toned muscles, so she’s pretty hard in some places and she can lift you pretty easily,” She continued as she started to lightly finger herself. “Oh, and she also has a massive-”

“Hey!” The pink alicorn interrupted, drawing the two younger mares to look at each other, their faces centimeters apart. “That’s her secret to reveal!” She explained, leaving them in silence for a few seconds before she licked her sister-in-law’s nose, sending them both to go into a giggle fit.

“Girls!” Celestia shouted, trying to remain calm, despite the incredibly sexual images her fellow princess forced into her head. It got the other ponies to calm down and look at her again after a couple seconds, allowing her to add, “I don’t know what’s gotten into you two, but Chrysalis is the enemy here. She’s a changeling queen and she tried to take over Equestria a few years ago. Remember?”

Twilight took a moment to think before replying, “Yes, but I also remember that people can change. Fluttershy and I managed to reform the literal God of Chaos and somepony who attempted to destroy the timeline out of petty revenge respectively! What’s Mistress to that?!” She pouted at the end while crossing her arms.

The solar princess paused because of the mention of ‘Mistress’, but quickly shook it off to respond, “I know that Chrysalis can change, it just she clearly isn’t! She has already taken over your minds and trapped you here via making you lust for her body!”

The lavender alicorn merely snorted at her former mentor as her look turned indignant. “She’s just jelly,” She said while looking over to Cadence. “She knows that Mistress is way hotter than her, and is just trying to make us think she’s evil so we’ll love her instead.”

“What?!” Celestia shouted in response, sounding baffled and insulted. “She is evil, and I do love you,” She said, trying to reign in her anger, “How could you possibly think otherwise?”

“Of course you love me,” Twilight replied, “But not in a romantic sense. Mistress truly loves us, and she’s so nice to us! She gave us this really big place to live with her and doesn’t even give us any responsibilities for it!”

“Besides the sex,” Cadence added in a matter-of-fact tone.

“Yes,” The lilac alicorn replied somewhat mirthfully. “But it’s not like we don’t want to do it; after all, still makes us feel really good with it,” She explained, her gaze turning dreamy.

“Oh, and Mistress also wants you to join us, so that way you’ll feel really good and won’t be responsible for running Equestria anymore!” The other mentally enslaved princess added with similar joy.

Celestia was taken aback by this statement, forcing immense disbelief and anger into her response. “How can you say that?! I can’t go shirking my responsibilities for personal gain, else the whole of Equestria will devolve into chaos! Not to mention what would happen to the world if I wasn’t there to move the Sun!”

“You know, ‘Tia...” A malicious voice echoed through the cave as hoof-steps were heard entering it, “I don’t see why you need to worry yourself with those matters. I can take over for you.”

The white mare prepared a violent response at her captor, but her voice died in her throat as she saw Queen Chrysalis enter the cave, not out of who she was, but of what she had. She gawked at the changeling’s massive, yet still flaccid stallionhood, staring at it in aroused awe as it bounced around hypnotically while its owner kept strutting closer.

The changeling eventually stopped in front of her new prisoner, and begun snickering at her utter enthrallment. “Oh, you like this?” She said sultrily, failing to draw the princess’s attention away from her shaft. “This is my new plan: I’m going to fuck you into submission,” She explained as she took hold of her cock with a hand and slowly started to stroke it, “And then I’m going to impregnate you, so that way you can be the inception of my new changeling army.”

Celestia closed her eyes in an attempt to pull her focus from the huge pillar of meat, but only succeeded in making her picture things that it may later do to her, before she responded with a wavering voice that defied the sternness she wanted, “I’m never going to allow that to happen.”

“I know,” Chrysalis replied calmly, then quickly went into a sensual tone, “That’s what’s going to make this so fun.”

The solar princess then opened her eyes wide to see the other person right in front of her, and looked in dread at the huge, green, and now-erect stallionhood not five centimeters from her face, and peripherally noticing the warm breaths on each of her nipples. She clamped her mouth hard to prevent her throat getting stuffed, even if she did find the thought rather arousing.

“It’s just like Nightmare...” She thought, the very mention of the name bringing back the lewd dreams she had and dampening her sex slightly. “No!” She interjected, “I must resist, for the good of Equestria!”

She shivered noticeably as she felt fingers touch her lips, then start to try to force themselves into her mouth. She next felt a warm, wet sensation on her left nipple, implying somepony had licked it. It made her loosen her lips slightly, but immediately clamped them back together, preventing her captor from entering.

She gasped audibly when she felt her right nipple getting bit, and her mouth was quickly filled by a multitude of black, chitin-covered fingers that begun to separate her lips further. The two hands the fingers belonged to resisted the pressure the princess put on them, eventually managing to make her mouth gape enough to make her jaws hurt.

Celestia slowly lost the ability to resist the huge shaft bobbing in front of her muzzle, as the intense musk it put off made its way into her, filling her mind with lewd thoughts of submission. She did manage to muster enough strength to pull her focus from the sexual facets of her current situation to gaze upon her captor with disdain, to which an amused look was returned.

Chrysalis than started to slowly move her stallionhood forward, putting it between her hands and shoving, making it fit snugly multiple centimeters in before she pulled her hands back out, letting the mouth they previously pulled open clamp down on her cock. She resumed her shoving, her motions now going smoother due to the saliva encompassing her shaft and her hands pushing on the back of her captive’s head while her focus was turned to said captive’s face. She couldn’t help but release a mirthful chuckle from it; the very princess of the Sun herself, looking at her with a stern glare (or at least an attempted one) with a massive cock shoved into her maw.

The white princess’s glare faltered when she took stock of her situation, noting the very dominant creature getting her way with her in a very lewd manner whilst two of her fellow princesses attached their mouths to her nipples and sucked, the loud slurps produced thereby being echoed by quieter ones as the cock in her own mouth kept moving further in. She kept losing resistance as her throat became more stuffed, finally becoming placid after her captor’s medial ring made its way into her mouth, yet she still harbored internal contempt.

The changeling queen let out a lustful sigh when she finally hilted in her newest prisoner, letting the alicorn adjust to the sensation before slowly pulling her cock back out, stopping just before her medial ring. She next thrust back in quickly, an audible slap being made when her groin connected with her captive’s muzzle, her pendulous balls lightly brushing the mare’s chin.

Chrysalis pulled back and thrusted again, slightly faster and more powerful this time, making the pony below gag slightly from the forcefulness, yet this only furthered her arousal at the situation. The dominance shown to her by her captor was getting to her subconscious, slowly lowering her resistance to it as her thoughts became plagued by replays of her dreams, some of them having Nightmare replaced with the changeling currently stuffing her face, which all only served to grow her arousal even more.

“No! I can’t keep thinking like that!” Celestia yelled at herself internally while the shaft in her throat went into a rhythm of pulling back and thrusting forward, slowly pulling back more on each cycle. “I need to resist, so I can serve Equestria as a public fuck-hole!” She growled mentally as her thought became more lust-addled, the soft moans from her captor not helping in the slightest. “As a ruler!” She amended, “So that way I can stop any more threats like a second invasion of changelings and their sexy leader or if my sister turns back into that dominatrix, Nightmare!”

She growled mentally again before she got her attention pulled back to her current physical situation, noticing the now rather violent motions the heavily-endowed queen made as she managed to force nearly her entire shaft out and back in on each thrust, her weighty balls loudly smacking into the bottom of her muzzle. Her attention was also drawn to the taste of the stallionhood, the intense musk and slight saltiness portraying the pure sexuality of it and addling her mind ever further.

“I-I need to resist the temptation,” Celestia commanded herself. “Because... because...” She continued, but was unable to find an explanation to deny herself this sweet, savoury, sexy cock shoved into her maw. Her resistance rapidly dwindled as she once again took stock in her situation, and still found no reason to defy, so she merely let that part of her sit in the back of her mind and stew as she basked in the rough and sexual sensations demanding her attention.

Now that her attention was back on reality, she noticed the intense moaning coming from the changeling rutting her face while her motions seemed to be at their peak, her hips and stallionhood a blur as they quickly moved back and forth, loud slapping sounds being made whenever they connected with the alicorn’s muzzle. The sounds mostly drowned out the moaning and slurping coming from the other two mares who were suckling on her nipples, now seeming to be getting milk from them, while they fingered themselves vigourously.

Chrysalis suddenly made one final push, forcing her cock into her white prisoner with all her might as she let forth a loud, guttural groan of pleasure, her shaft beginning to spew huge ropes of cum into the mare’s throat. Said mare then felt the cum bulge her captor’s cock slightly as it went through it, then gush straight into her stomach, powerfully smacking against the bottom of it and inciting a small level of pain in a way that she had never felt before, yet managing to heighten her lust all the more.

Another type of pleasurable pain began to work its way into Celestia, starting off as a negligible discomfort on her belly, but slowly becoming worse (or rather, better, because of her sadomasochistic tendencies). The princess felt this once it became hard to ignore and put one of her hands on her belly, finding it to be quite a bit larger than usual, making her seem multiple months pregnant.

The sensual sensations took a while to stop, after which the dominant changeling pulled her shaft out of her captive, a lewd slurping sound signify its retreat, followed by a wet pop as the flare came free. The alicorn then looked at her captor while they both panted heavily, from exhaustion and suffocation respectively, both holding an expression of pure lust on their faces.

“Did... you like that?” Chrysalis asked tiredly as she looked down at the solar princess.

Celestia took several seconds for some of her faculties to return before panting out, “I... I...”

“Well, it looks like I’m going to be more thorough,” The queen said huskily, then crouched down slightly and grabbed her prisoner’s shoulders before shoving her onto her back, forcing the two other alicorns to stop their nursing as the nipples were plucked from their mouths. The younger mares then looked on in slight disappointment as their milk source was taken away from them, the pony it was attached to looking up in awed arousal at her pseudo-Mistress.

The changeling looked down on the pony she now lay upon, their breasts squished together and their muzzles nearly touching while the former’s huge cock was compressed between their bellies, the latter’s being slightly displaced by it. The discomfort Celestia felt by the displacement was heavily outweighed by her current position however, finding herself enthralled by the submissive stance she now held, not even peripherally noticing the two other captives beginning to make out passionately in the background. The dominant creature above her also began to hold her reverie for a different reason: she was beautiful.

Not just beautiful in the sexual way, though there was certainly a lot in the way of that, given her voluptuous figure and dominatrix demeanor, but truly, romantically beautiful. Her dark complexion gave her a level of mysteriousness and nuance that the alicorn couldn’t help but love, the holes in her body provided her a unique look that did not exist within normal pony society, and her powerful confidence washed away any lingering worries as it was clear she would take on any threats to her loves herself, protecting them at any cost. She was baffled as to how she didn’t see it before, how it took such sexual misdeeds to get her to realize the truth, but now that she had it, she wasn’t letting it go.

The solar mare leaned her head up and pressed her lips to Chrysalis’s, portraying her love for the changeling in the clearest way possible, and truly hoping that it went requited.

In a great stroke of luck, it seemed to have. After a moment’s pause, likely from not entirely expecting the action, the changeling pressed her lips back, reciprocating the kiss, and thereby, the love it showed. The sensation of the kiss was incredible, the combating harshness and softness of the creature passionately making out with her completely blanked her mind for the duration of the session, only beginning to return after they separated.

“I-I love you, Chrys- no, Mistress,” Celestia declared as her senses returned to her, leaving her staring back into her partner’s vibrant green eyes, that seemed to be portraying a mix of excitement, love, and confusion.

“I love you too, Tia,” The queen responded after a few seconds of contemplation, her tone now a level of determined as they resumed their intercourse, now as much an expression of love as of lust.
