A Memorable Honeymoon

Celestia and Luna left the chariot outside of the changeling hive. While they could very well have flown or teleported there on their own, as rulers of Equestria it was important to keep up appearances when it comes to conduct state visits just as these. Even more so as it was also a diplomatic visit with the newly-led Changeling Hive.

By now King Thorax had managed to unite the changelings all under him, even his wayward brother Prince Pharynx.

Not that Celestia is one to speak, considering her very own grumpy sister was less than thrilled with what they were about to do. The reservations she had about this mission were valid of course, but she was sure it will do some good for the reclusive shut-in.

“Okay, remember the plan and let me do the talking. This might be a bit overwhelming for men.”

“And tis not so for us?” Luna asked with a light glare, making her sigh out.

“I know, just...try and enjoy your stay. Who knows, maybe you will see something that you like?” Celestia jabbed her wing into Luna’s side who snorted.

“The day I see something I like in this hive or in changelings is the day I will admit that you are the wiser of the two of us.”

“Fair enough,” she said as they walked inside, two guards decked in armor nodding to them in greeting.

Walking into the large arc they came to the throne room, which had big holes in the walls to the side acting as windows.

And then the changeling guards lined up in perfect synchronization, halberds raised in an arc to create a pathway for them.

Perfect choreography. Better than what the best of their royal guards could do. Luna for one eyed this with great interest as she walked alongside her sister to the elevated throne where Thorax was sitting with Pharynx being on a smaller one.

“...We weren’t quite expecting that big of a reception. Especially such an military honor…” Luna voiced.

Celestia smirked triumphantly.

The moon princess noticed this, huffing, “I-I still am not happy with the situation!”

Any banter was halted as they arrived, Thorax gesturing for them to get up the steps on the broader elevated platform where the thrones were located.

“King Thorax. It is a pleasure to meet you again. Prince Pharynx.”

She nodded to both of them as Luna gave some small nods as well.

“I am happy that you are here to pay us a visit Princess! Please sit down,” he offered, while there were no other seating possibilities in sight.

She blinked her eyes a bit, before two guards suddenly stepped up, flames licking across their forms as they turned into thrones, just like Thorax own.

Celestia had to hold back a grimace at this strange...seating. She was a diplomat and knew very well that different cultures handled things differently and still...it surprised her.

And her own sister did not mind.

Luna seemed rather happy as she planted her ass down, smiling now.

“Oh what a joy! These soldiers are trained extraordinarily well, and to even provide rulers such as us a proper seating! Such obedience and dedication is quite marvelous,” the blue alicorn praised as Celestia slowly lowered herself on the seat, trying to ignore the...uniqueness of it.

Pharynxs chest swelled up in pride.

“Of course! I trained them myself! If you want to do a job, you are best off doing it yourself! And as fellow rulers it is important that we offer such arrangements. I am a bit surprised though that you are that fine with it. Expected some raised eyebrows or even being appalled, being ponies and all.”

“There is hardly a reason for it, and this would be quite rude! We do rather appreciate that thou have gotten some commoners to seat for us like thou did.”

Thorax smiled awkwardly as the two were getting along far better than expected. Celestia mirrored his smile, only with her experience she could mask all of her own awkwardness, while additionally refraining herself barely from smacking her younger sibling upside the head.

“King Thorax, it is a pleasure. We are happy you were able to accommodate our visit to the hive.”

“Oh, it is nothing. While we are a new nation, it is more of a slow start yet. Not too many diplomats were willing to come here. Aside from Ember and Spike that is,” he told her, waving a hoof with a friendly smile.

“It is a problem. And it also is a problem we are willing to solve with you. In fact it is the main reason for our visit. While we are more than happy to start diplomatic relationships with you, others are...less than accepting of it. Queen Chrysalis’s attacks are still fresh on the mind of many ponies and as loathe as I am to admit it, there are many who are opposing the idea of accepting the changeling nation.”

Thorax blinked in surprise while Pharynx squinted his eyes at her. Luna gave a slight nod.

“Tis true. Especially those foals that call themselves our ministers are the loudest rabble rousers amongst the lot. Sadly the military as well, albeit that is more understandable as many of those have fought against your own army in the past.”

Thorax mulled it over, the words that hit him seeming rather heavy.

“And what does that mean for us?”

Celestia sighed out softly as she lowered her head.

“For now we quelled the calls for subjugation against the changeling race. But they no doubt will come up again as, like they put it, want to ensure your race can never conquer Equestria again.”

The prince sprung up enraged, stomping his hoof on the floor, “We shall not stand for this! And if you even try to attempt anything…” he said, walking in front of his brother, the threat clear to everypony involved.

The king in question was scared, heartbeat accelerated as much as his breathing. They were just building up their nation after having defeated Chrysalis. And now his people were once more in danger! He wasn’t quite sure how to solve this as they couldn’t risk being seen as the aggressor in any way, lest the other nations adopt the same stance on changelings.

Celestia lifted up her hooves in comfort, trying to quell the fear and rage in the two changeling royals.

“We do not intend to fight, but offer a solution to this problem and make sure that your nation will prosper properly,” she quickly rushed out, causing Thorax to blink and Pharynx to raise a brow at her.

“A solution you say?” the prince asked, eyes travelling from one mare to the other, Luna scratching her cheek as she avoided his eyes, clearly still not comfortable with the ‘solution’.

“Tis an awkward one,” she supplied, making Pharynx and Thorax stare back at the big white alicorn for clarification.

She coughed in her hoof, preparing herself mentally for what she is about to say.

“It is an issue of trust in your race. Trust that we have in spades and that we could try to share. It is a rather old tool of diplomacy that has gone out of fashion for many nations, but it is in our opinion the only and best way to resolve things without sparking any conflict.”

“...And that tool is?” Thorax asked, sitting stiffly on his throne as he looked at the mare in worry and anticipation.

“Marriage.”

It was such a simple word, and yet a word with so much power behind it in this situation. The king’s mouth flapped uselessly for a moment as he tried to process it all.

“W-Well, you mean one of your nobles with one of our changeling officials?”

“No, between us four.”

The clarification seemed to break Thorax for a moment. This isn’t what he had in mind. In all honesty he had no plans whatsoever in marrying anyone at this moment. Leading his changelings took most of his attention away and he never had taken the time to date back when he was under Chrysalis or during the time when he lived in the Crystal Empire. The latter being mainly the case because he was happy enough getting used to living among ponies even with Princess Cadance prodding him and trying to commit him into a relationship.

He looked to his brother for his opinion on this. The changeling prince had a rather intense air about him as he stared at Celestia seriously.

No doubt he had a rather important question to as-

“...I don’t have to marry the fat one, do I?”

Celestia’s cheeks flushed as Pharynx pointed at her. All was silent for a moment, shock coloring all of their faces, at least until it was broken with her sister’s not-so-helpfully cracking up.

“Hehe! Nay! Thou shall get the one that is at least in shape! Hehe ha!”

The king at least had the dignity to gawk at his insolent brother.

“P-Pharynx! You can’t say that!”

“But I just did,” he told him, cocking his head to the side in confusion.

He rubbed his temple. Even after trying to get his brother to learn proper etiquette, he had little interest in learning and remembering it.

His head bowed in apology towards the mare that was just trying her best to help them.

“I’m so sorry about this. Pharynx, he...means well. It is just that he is rather blunt sometimes. More than is good for him or our race.”

“Hehehe. Fear not noble changeling. We do not take any offense to his openness. In fact we find it rather charming. Isn’t that right, sister?” Luna said, elbowing the mare lightly.

“...Yes...very delightful…” she forced out with a smile, trying her best to move past this, but making a note in her head to take revenge on Pharynx for this, one way or another.

Thorax is relieved to hear that his brother’s behavior isn’t having any negative repercussions. He gave a slight apologetic smile to the two of them as he finally got around to thinking about their proposal. A...marriage proposal.

It was a strange new situation for him. Marriage normally isn’t a bad thing. He just wasn’t sure about committing himself to it yet. And that fast without getting to know the mare first. It mattered little of course in the face of certain destruction as this was, as they said, the only lifeline he had for his changelings. There was not much of a choice if he wanted to keep peace with his nation.

He took a calming breath, Cadance being a great teacher in this, as he looked at Celestia with determination.

“I...accept. If it is for the sake of the changelings I don’t mind. Though me alone should be enough. There is no need to drag my brother into this.”

“If you accept, so do I,” Pharynx simply stated, making the king turn his head towards him in surprise.

“Pharynx, you don’t need to do thi-”

“I do. Don’t try to stop me. We are brothers, so we do everything together.”

“How noble,” Luna noted with a warm smile at the prince who nodded to her.

“It is my duty.”

“Well, I do like dutiful studs…”

The white alicorn coughed embarrassedly in her hoof, breaking this up before this could get any more out of hoof. At least her sister was warming up to the idea now, but they had to get back on topic. “Now that we are in an agreement it is time to flesh out the details further. We will explain to you the outline for this event. Let’s start with…”

- A few weeks later -

“I do.”

“And so do we! Huzzah!”

“I declare you then with the authority of the crown to husband and mare,” Twilight finished with a smile, Luna instantly diving for the changeling prince, wrestling him to the ground, only for him to roll her around as she claimed his mouth. It was...unique.

Celestia just smiled and waved with the king nervously. Smile and waved.

Trying to act normal before the mare demurely turns to him as he turned to her and they kissed.

It were a few crazy weeks. The princess wanted to get things done as quickly as possible to stop any trouble from brewing so they had immediately announced the wedding as they exchanged with each other about their people, traditions and more.

A crash course on culture if you will.

Luna and Pharynx hereby were more interested in the military aspect of it all, happily chatting each other up, Pharynx being more stoic and Luna being more giddy in this, as they started to connect.

By the end of the weeks her lunar sister couldn’t wait to slobber up his face during the wedding.

They started to have sparrs and friendly wrestling matches as well. And it took Celestia and Thorax an entire week to convince the two to not go into an all-out battle for dominance after the wedding was done.

Celestia shuddered to think about the nightmares she had with Pharynx punching her sister in the face and the outrage it would cause.

And it was still hard enough to sell this ‘bonding activity’ as a changeling tradition during marriage.

But it was all okay now. She let the many headaches fade into the back of her mind as she enjoyed Thorax’s lips. Twilight blushed and smiled at that, feeling better after avoiding her eyes from the other couple.

Holding the ceremony in Canterlot was still a tense affair, even without all the troubles, and the white alicorn was more than happy once it as well as the afterparty was over. The decision to hold the ceremony in front of all these prying noble eyes and the press was made to show that this was a willing reunion and not a kidnapping or any other changeling trick. It was the only thing she allowed though, as they would have their honeymoon in the changeling hive to catch a break.

Changelings were wondrous creatures with a deeper mind connection. They could send out signals when they wanted to be left alone and the other changelings would accept that, granting them privacy.

Celestia knows the press and nobles wouldn’t even let her have a few weeks of rest and privacy for her honeymoon.

So once all temporary goodbyes were said, did they enter the chariot that was pulled by changelings to their destination, which was right through a portal inside a room that was adjacent to the gardens where the afterparty was held. The castle had enough rooms to repurpose and using a big empty one to start up a portal hub? It was a dream come true for Twilight who had worked eagerly to connect countries. They just removed the doors and widened the entrance to repurpose it. Adjustments that were easily performed. And it was needed, considering even with the unions they would still have to travel between nations for their work.

It would have been a nice silent ride too if not for her sister and her brother-in-law Pharynx Luna humping into each other, with her sister sitting on top of him.

What followed was a changeling tradition of showing off their brides to all the changelings of their hive before they thankfully were able to retreat into the large bedroom that Thorax had prepared.

Celestia slumped into the bed, back first, the cushy surface wobbling a bit under the sheets. Some sort of gel that does feel rather comfortable to lay on.

Her sister sighed out, wiping some sweat of her brow. “T”was most tiring. But now all is done and the changeling race is saved. Now...you best appreciate all the efforts we have put in,” she said with a smirk, facing Pharynx who was about the same height as her.

“Fucking for dominance?” he asked her bluntly, interpreting her hidden signs.

“Fucking for dominance,” she confirmed as she once again threw herself on him, starting to rip his suit off, as he did the same with her beautiful night-themed dress.

Thorax sat down next to Celestia as they eyed the pair in amusement, albeit Celestia had cringed a bit as the clothes were obliterated. No doubt Rarity would have a seizure were she to witness it.

Seemed like they didn’t waste any time as Luna bowled him to the ground and jumped with her pussy on his dick in one fluid motion. Almost...trained.

“...How high are the chances that they have been fornicating around with each other before the wedding?” Celestia mused, which the changeling king mulled over.

“Well...rather high I would say. Your sister seems rather direct and Pharynx is never one to turn down a challenge, as he is very prideful.”

The alicorn couldn’t help but hum in agreement as her sister was moaning and riding the changeling as she held his legs down with her magic. It is a bit vexing that she had to agree, considering she knew her sister was a virgin before all of this. So for her to simply and almost too eagerly do things like this before the wedding… It made her sigh out.

“I want to protest but I know it is most likely true. My sister is a bit...special and...rebellious.”

“As is my brother...Though we are both stalling at his point.”

Celestia nodded in agreement from her lying position. “We are… I honestly am new to things like this as well. Never had much time for romance with responsibilities weighing me down.”

“Then we are alike. Maybe we should start off small with pleasing each other...orally.”

The white mare raised a brow at him. “Oh?”

Thorax blushed a bit as he scratched his cheek with a hoof. “Changelings are required in their education to know about sex, though I only ever did oral at most back in the day. Gathering love was mandatory. And...some ways were easier to do than others.”

This made sense and they went a bit over the history of changeling sex-ed during the last weeks as well now that she thought about it. Her horn lit up and she teleported her dress and his suit off, no need to be as destructive as the other two.

“I will let you lead then, as you have greater experience in all of this.”

The changeling nodded, his large size looming over her. While Celestia was larger than any pony, this king managed to thwart her height by a bit. Almost half a head in fact.

She had to admit that having a larger male to look up to was alluring in a strange way. Maybe it were her instincts kicking in, liking the thought of a strong protector. A strong virile male. It is a thought that made her heart flutter.

He started to crawl over her body, positioning himself in an opposite direction over her on all fours, so his junk was positioned over her head.

The large dark green horsecock was already emergin from its sheath, showing off a truly impressive length, no doubt above average by far. Maybe as big as a yak would be?

As she was staring at it entranced, the wide flat head, he was already a step ahead, grabbing her juicy thighs with his hooves as his head was buried into her snatch in a moment.

She cried out in pleasure as a long thick tongue was shoved inside, swiping along her depths and exploring them curiously.

His hips lowered, causing his member to meet her cheek. This felt rather good. Maybe it was his experience that made her quiver after only a few seconds of this service?

It would be impudent not to return the favor, so her magic grabbed his shaft and aligned it with her mouth. Her beautiful white lips opened as she invited the tip in. Her bigger frame meant that she at least had a bigger mouth, so she managed to get the tip in with only a little strain. She doubted normal changeling mares or even Luna could handle it as well as her.

They were rather size compatible and yet she still struggled a bit as he started to slowly thrust his hips into her. That was him being considerate, seeing how he managed to never go as deep as to breach her throat.

Celestia could hardly complain as she simply licked and sucked on it in a rhythm as he adjusted his grip on her and buried his muzzle deeper into her pussy. He actually did shove his muzzle into her twat directly, the spreading making her muffledly moan on his magnificent cock.

Her tongue trailed along the length, some precum spreading on her tongue. This was heavenly and she couldn’t help but wonder what the real deal would be like if this already was setting her on fire. Her mind imagined it, this large shape, invading her pink walls even more than it did her mouth. Ravaging her body…

...Maybe she should tell Thorax to be more dominant about this. She wondered what it would be like. Maybe some incentive?

Her pleasure-addled mind quickly put her magic on his behind and on his next thrust, shoved it in deeper.

Celestia gagged as the shaft had enough force behind it to stab down into her gullet, Thorax groaning into her fat juicy marehood as he felt her throat contract around it, seemingly milking him. He stayed like that for a moment before pulling back.

It was an interesting experience for the alicorn. The dominance she forced upon him was...fun, so her magic gave him another push. This time lighter, to tell him it was okay to go deeper and faster.

And Thorax accepted it. His hips went down, skewering her neck and showing off an obscene cock outline. At the same time he shoved his muzzle into her as deep as he could as his tongue slithered along her sensitive walls, trying to claim as much of them as he could.

Celestia’s back arched, her pussy overflowing with her juices as he went to town at her, filling her from both ends in a way she didn’t know she needed.

The blissful muffled sounds that escaped her were enough for Thorax to keep up his assault on her, while also groaning into her as he derived a lot of pleasure from this himself.

A few minutes into this and his face was a mess, as was Celestia’s. Their oral session was intense with heavy pants and wet squishes.

It took no time at all from there for her to cum, a muffled cry escaping her lips before her throat was silenced as the king’s shaft went right down her throat again.

Thorax groaned, enjoying the vibrations and the splashing of marcum on his face as he increased his speed. His dark green balls slapped against the forehead of the leader of Equestria’s nation. A rather lewd thought which was quickly bringing him to the point of no return.

He speared her gullet one final time as he groaned, seed shooting down into her stomach as his tongue lapped and tasted her more.

Once both of their orgasms subsided, did he flop down next to her breathing heavily.

“That was rather...enjoyable,” Celestia spoke up, making him chuckle a bit.

“It was. But it was mere foreplay still.”

Celestia then sat up, her body rolling over him, forelegs on each side of his body and a soaked marehood meeting his still erect pulsing shaft. She gave him a smoldering look, that made his dick even harder as he stared at the horny mare just as lustfully.

With one quick movement she smacked her wide ass down on his length, sinking it all into her in one go.

She squealed as she felt it reach far deeper than she imagined. The feeling infinitely better than from his tongue and that tongue alone that had been driving her crazy.

Her large body bounced on his as he the changeling monarch set his hooves hesitantly on her hips and cutie mark to guide her.

“N-No need to hold back. I-I rather liked, aah! H-How dominant you were before. I am a big maaaaahhhhre, a-and can handle it!” she panted and moaned out relentlessly, feeling his grip tighten as he started to suddenly meet her thrusts.

As her body crashed down, his hips sprung up, meeting hers with a spray of wet juices.

Celestia faltered at the jolt of pleasure, temporarily stunned, though Thorax wasn’t so he kept it up, burying himself balls deep into her. He even was fucking right into her womb with how long his tool was, making sure the mare could feel every inch of her insides being invaded and used by him.

She tried to focus again, her hips starting to crash back down into him wetly as she bit her lips, muffling her moans a bit.

With how things were going she would cum in no time at all. She hoped Thorax felt the same as she could barely wait for him to douse her insides in his virile seed.

“C-Can’t believe how goooooood this feels,” she moaned out as Thorax sat up, his lips quickly covering hers as his long thick tongue was shoved into her mouth while his hooves went to her plush ass, fondling it as he pulled her up and down.

Celestia’s hooves wrapped around his strong body, crying out more as she felt like she was melting into him. She was almost reaching her limit again, so she pulled off his lips.

“I-I am cumming, Thorax! P-Please cum inside me! Mark me! Fill me with your changeling brood!” she begged, as the larger male groaned.

“I will! I am about to blow and breed your womb with my changeling seed!” the monarch exclaimed as he felt her juices gushing over his crotch. He grunted, slamming her entire body up and down with ease. A strength that did impress and make the white alicorn soak herself even more in arousal.

She was manhandled as he was getting ready to claim her. And then, just as her climax was about to end he did cum. A groan from his lips was all the warning she got as he hilted himself fully into her pussy as his cum exploded into her womb.

She felt it fill up to the brim, expanding it a bit from the sheer volume before it stopped, making sure that she was pregnant. She went limp into his legs, panting as she was taking a moment to recover.

“I-I did it now. I bred the princess,” Thorax said as Pharynx stood next to the bed, Luna’s ass in hoof as he was fucking her.

“Didn’t we plan to do this from the start,” he wondered, making his brother chuckle.

“Maybe…And we can do this all night too now that I think about it.”

Pharynx grinned, “Then you should do so, show this submissive pony mare what you are made of as the great changeling king.”

A nod followed as he looked at the panting mare he held. A submissive? It seemed to fit with her demeanor, albeit it is a bit surprising in his mind.

He noticed Luna giggling. “A submissive… Never thought I would hear that about her of all ponies. But that is fine to me. Put her in her place. And you, Pharynx, best get back to rutting us!” the night princess demanded, making him grunt as her legs were wrapped around his body and she thrust down onto his large shaft.

The green changeling put his attention back on the alicorn, bending forward and laying her back on the bed. He pulled out, his still erect dick flopping free before setting it on the mare’s ass making her whinny in surprise.

“T-That is...new…” she noted, albeit didn’t say anything for him to stop.

So Thorax pressed on.

He groaned as he managed to press his prick slowly into her pucker, parting it as it was squeezing hard on him. It was much tighter than her pussy and it had a certain allure to it.

In light of this he started to slowly thrust in and outside of her, claiming inch after inch of that new tunnel for himself. The lubrication from their prior lovemaking helped tremendously in this endeavor, making it slide more easily.

It felt as if he was exploring every inch of her, claiming every inch of her. Something that made her blush as she stared into his eyes. All of her four hooves wrapped around his body, pulling him tighter against her and helping him as his medial ring slipped into her sphincter as well.

Another minute in and he managed to cram it all inside of her ass, making her moan out at the fullness as she felt his balls touching her dock.

It was amazing how fast he adjusted his movements as he sped up a short time later again, hammering her bowels straight to fit well on his prick.

Celestia pulled him into another kiss, the changeling king complying immediately as if reading her mind. Only this time his long tongue didn’t stop in her mouth, but went right down her esophagus, filling it as well.

The white alicorn gagged in surprise, but showed no signs of wanting to pull back.

Thorax did though, pulling his tongue back enough for her to breathe, before shoving it right back, practically tonguefucking it and adding another layer of domination to the pile.

His hooves made sure to hold her ass steady as well as her grip on his body while he was already going for another pleasure-induced high.

Celestia could feel it in her walls, the massive throb of a cock that was about to fill her up.

And then he did on the next dive into her, his length pumping out his white seed into her and painting her anal walls white.

It was a fun little sensation for the alicorn mare. A certain novelty like the other fun they had before, while seeming a bit more down and dirty compared to regular sex.

She felt herself sigh out in disappointment as his shaft stopped firing inside of her and his tongue was pulled back out of her.

Maybe she shouldn’t feel that way, considering that he already lasted longer than most ponies would, if her general knowledge was right.

This mindset didn’t quite prepare her for his horn flashing and cleaning his cock, before he turned her around on all fours with her upper half lowered to the bed and her ass up in the air as her marehood once again was penetrated.

He was still as hard as when they started. Not at all softening up after having spent three loads already. She had underestimated him considerably, making her wonder for a moment if this was a changeling trait, or if Thorax had simply genes that good.

The thought about the latter made her subconsciously spread her legs more as she was fucked like a mere bitch in heat from behind.

That mental image was as degrading as it was alluring. It just felt so right to her. To just submit to the taller superior male that was rutting her mercilessly.

The way she drooled onto the sheets completely undignified was getting to her too.

She wished she had a mirror, just so she could see her face and to know how much Thorax was messing her up as he was fucking her cum-stuffed womb.

A grand elegant mother figure. A pony of authority and kindness.

And she was reduced to a deplorable state. Her smile twitched up at that, moans and squeals getting louder and more eager as she held her ass up for him, her screams begging for him to do her harder.

The king did his best to comply with how his moist hard carapace smacked against her as he buried his entire member into her deeply.

By then Luna joined the fray, mirroring Celestia’s pose, only that her upper half wasn’t on the bed drooling out. She lit up her magic, pulling her to her hooves and then smooching her shamelessly.

Celestia moaned in surprise as her sister’s tongue invaded her mouth, though with how aroused she was, she didn’t protest it.

Pharynx gave his brother a grin as he was on top of the moon princess, riding her pussy still.

The king himself gave a nod as they both fucked their respective wives into each other, with Luna’s hooves wrapping around Celestia’s long neck, who herself mirrored this as their chests met.

Squelches could be heard from either mare’s behinds, wet marecum and pre, as well as changeling spunk in Celestia’s case was smearing around their rears and dripping down on the sheets.

The white mare felt a bit sorry for the poor changeling maids that had to clean it, though wondered if such lusty juices could actually contain traces of love to feed them.

It was a bit of a silly thought. Especially in her position, making out with her own sister. But nopony minded it in the room, so it felt strange to her to say anything against. Even more so as it did feel rather nice.

Their tongues intertwined, Luna easily toying with hers and looking rather smug about it. Pharynx appears to have taught her some strange and perverted things.

And while her rational side wanted to scold him for it, her lusty side hopes to get taught more about this as well.

Luckily her sister was more than happy to show her the ropes.

Her tongue moved around slowly, showing her how to wrap around her own in unison, to wrestle and play as their asses were squished by the strong changeling hips on each side.

It was a perverted image. To just see the two celestial sisters entranced in this pleasure, making out as their husbands were making sure that they couldn’t be called pure anymore by any pony, changeling or otherwise.

Innocence lost, pleasure gained. And Celestia didn’t want to miss this pleasure in her life anymore after having tasted it once already in each of her holes.

Thorax agreed, moaning out as he had a tight grip on the mare’s body, loving just how her velvety insides wrapped around him, pulling him with each new dive into her.

His brother was swiftly reaching his limit, his hip thrusts increasing as Luna dutifully held her plot steady for him to release his load.

“Cumming!” he groaned, dick pulsing with need before he pulled out and put it between the dark mare’s ass cheeks. Cum was firing out, streaks of white landing on the moaning dark mare’s back.

Seeing this aroused Thorax as he stepped up his game as well, thrusts increasing as he grunted.

“I-Inside!” Celestia begged, parting lips from her sister for but a moment before Luna claimed her muzzle again. And while Thorax did want to streak her back as well, he decided to listen to her this time and grant her the privilege of his seed gracing her womb once more.

She came, clenching and pulling him in, so Thorax did as well, balls churning with their baby batter before it was fired inside her, filling her up again and making her belly bulge out more.

He panted, as much as Celestia after Luna had released her lips, both of them enjoying the tranquility of the moment.

A moment that was interrupted almost immediately.

The lunar princess pushed her husband off her and the bed with magic, making him fall on his back on the ground.

The dark alicorn spread her wings in authority. An authority that made Thorax almost snicker, considering the streaks of cum on her back that were undermining it. Only curiosity and the supposed seriousness she was emanating were holding him back here. It was a notion he shared with Celestia as they watched the scene unfold.

Luna glared down at Pharynx, snorting out air from her nostrils angrily.

“Now our dear husband. Why didst thee break your promise to impregnate us?” she demanded in answer, before continuing, “All these times we mated before and you used condoms, telling us how we will be bred thoroughly on the wedding night and yet this...load is on our back and not snugly crammed in our womb, no?”

Well, at least this confirmed that they did fool around before the wedding.

“Luna, it is very likely that he just slipped out by accident in the deciding moment,” her sister tried to placate her, but she stomped a hoof. Not that it had much effect on the cushy surface.

“Nay, sister! It was a deliberate pull out!”

“...Maybe he wanted to cum on your back first?” Thorax supplied as the dark mare shook her head, snout pointed skywards snottily.

“Nay to this as well, dear brother-in-law. He never uttered any wish to do so.”

This left the eyes all to turn to Pharynx who was standing by then again, raising a single brow as if not understanding what they were on about either.

“I did say you would be impregnated and I mean it. Impregnated by my brother that is.”

“WHAT?!” came it from all three as they stared slack-jawed at the changeling prince who just proclaimed this like it was the most normal thing in the world.

“Pharynx, why?!” Thorax finally asked, being the first to recover and wanting to hear that reasoning while Celestia activated her magic to catch her wayward little sister mid-air as she was pouncing towards the changeling prince, hoof raised to give him a proper beating, enraged as she was.

The changeling in question didn’t seem to understand the commotion as he shrugged and started to regale his point of view.

“It is only natural. You know, since our childhood, I have taken care of you, considered myself as your protector. A big brother that protects his little brother so to speak. It was my responsibility. But then you stood up to Chrysalis, transforming into a new form and saved all the changelings...something changed inside me since that day. I couldn’t see you anymore like a simple little brother. The love that radiates from you, the love you have for all of us changelings, is capable of feeding the whole hive. Because of you, changelings no longer had to scavenge scraps of love and food to survive. Us changelings could finally live. If Princess Cadance is the living embodiment of love for the ponies, then you are mine.”

A silence fell upon them, as they all processed this. Celestia and Luna mainly stayed silent as they knew this was a moment between the brothers, so they didn’t want to interrupt.

Thorax for one was rather disbelieving about it.

“B-But how does that make sense! You refused to change! Refused to listen to me!” he threw in, not understanding his brother’s actions.

Pharynx lowered his head. “I wasn’t able to protect you against Chrysalis. I didn’t think I deserved to be sustained by your love, so I wanted to do things the old way for myself, while also protecting the hive. It was just so I could at least attempt to make up for my failure. It was a foolish notion. You showed me that. And...I was honestly too ashamed to bring it up again.”

“Pharynx…” Thorax said in sympathy, pulling his dick out of Celestia before quickly fluttering next to him and pulling him close to his chest in a brotherly hug. “I had no idea you felt like that...albeit the whole ‘living embodiment of love’ thing is a bit...much,” he admitted, with a skewed smile.

“Maybe. But it is how I feel. Can I not admire my brother like this?” he asked, looking up, to which Thorax rubbed the back of his head.

“Okay… If you felt the entire time like this, I doubt anything will change behavior-wise between us.”

It was a nice little moment as the alicorn siblings smiled at the brothers. They looked fondly to each other as well, while the lunar sister sighed softly, her gaze turning back to her husband.

“...We guess it is admirable in a way,” Luna admitted, crossing her hooves as she was still held in her sister’s magic mid-air.

“Yes. This is why it would be an honor if my wife is sleeping with and being bred by my king.”

“...And thou ruined the mood just now.”

Luna was released, landing on the bed as her sister snickered.

“Come on now, Luna. You could at least sleep with him if that is what your husband wants,” her sister teased, making the younger sibling throw back a light glare at her.

Pharynx used this moment of distraction to hold her hoof as he sat in front of the bed.

“It would please me if you would do that and rethink the breeding part while you are sleeping with him. He no doubt has the best genes in the entire changeling race. Much better than mine. But regardless of that, I still like you. It is why I married you in the first place and not just because of the obligation.”

“...You are really bad with words,” Luna bemoaned, before letting out a sigh.

“If it helps, I don’t mind at all despite my prior teasing. We can all be adults about this matter. If that is what Pharynx wants, why not give it a try,” Celestia suggested, moving next to her sister and rubbing a wing on her back.

“Ugh...Well...If that is how you all feel, we suppose we could give it a shot at least,” she harrumphed, making Pharynx’s face light up like a foals on Hearth’s Warming Eve. She had to admit it was kinda cute and made her agreeing to it almost worth it.

Her gaze then wandered over to Thorax.

“I don’t mind it. If everyone agrees.”

“Fine then. But we will place a contraceptive spell upon us, to make sure no foals will be sired from this,” Luna said with a snort, horn lighting up as well as a part on her belly where her womb was.

She gave a satisfied work at her spellcraft, before she stood up and turned around. Celestia and Pharynx moved, the latter getting on the bed and laying next to the white alicorn as they gave her some distance.

By the end of it Luna laid with her front half on the bed, while her back half was standing on the ground. She couldn’t help but blush in this situation as her husband and sister were facing her, looking at her in this embarrassing situation.

And then she felt that massive dark green horsecock slide between her ass cheeks as he mounted her. It made her forgot them for a moment as she couldn’t help but gauge this size. It shouldn’t come as a surprise, but considering Thorax’s body was considerably bigger than his brother’s, so was his shaft. Could anypony aside from Celestia even take it?

She was about to reconsider her decision, but by then he had already pulled back and prodded the dark wet lips of her marehood, only to suddenly aim higher.

“Wait! That is the wrong hooooaaaaahhhhHHHHHH!” she screamed out, her tight pucker giving in and inviting the changeling’s cock into her.

Luckily his cock was as lubed up by her sister’s pussy and his cum as it was. It made it a lot easier for her, even as he was popping the anal cherry. A cherry she thought would go to her husband.

“I-It’s so big!” she moaned out at the strange new sensations while he started to move, stretching out her anal walls slowly.

“It is my king after all!” Pharynx said all too proudly and even her sister looked rather smug herself, much to Luna’s chagrin. Neither of them seemed to mind that he was the first to try out her ass, though she felt it only right to point it out.

“Y-You know, you fiend just robbed me of my anal cherry,” she said to Thorax between pants and moans as his medial ring slid into her. His slow insistent movements made sure to give her the time she needed to adjust as well as to slide in inch after inch of his majestic prick.

“So I did. I wanted to try it out. I hope neither you nor Pharynx mind,” he said, giving his brother an apologetic smile.

“Not at all. This is a great honor that you were the first to do this to my wife,” Pharynx said, waving him off.

“I will have some fun with this then~” he replied, getting a bit cocky and confident as he increased the rhythm of his plunges into her.

Luna pouted a bit at that. Something that the king quickly noticed as he leaned down.

“No need to worry. It is okay. Just enjoy the ride,” he told her, before latching onto her ear with his mouth, his tongue playing along its surface as he nibbled it softly.

This excited the lunar princess as she moaned out while he managed to work the rest of his shaft into her bowels. After it was done, he picked up his pace more, getting faster slowly as his balls slapped teasingly against her winking aroused marehood, making her imagine how it would feel for her if he does decide to penetrate it.

Traitorous thoughts in her mind, albeit seeing how her husband and sister wouldn’t mind, chances are she was overthinking it. Maybe she was the weird one here for holding such standards?

She decided to take Thorax’s advice in any case, letting herself get swept away as she just enjoyed the constant scraping of his big cock against her anal walls. In all honesty, she never picked herself to be an anal enthusiast, though could now see why her sister had enjoyed it prior. A bit uncomfortable at first, but then pleasing after a while as well. The by now constant teasing of her marehood by his large orbs helped.

It was not quite enough for her to get off before Thorax still.

As such she could hear his own groans reaching a crescendo, no doubt ready to blow a load inside her.

She spread her legs a bit, preparing for what was to cum, her own pleased sounds echoing along the room as Pharynx seemed to drink in her sensations eagerly.

‘We married a pervert,’ was the mare’s late realization as his brother hilted inside her.

Volley after volley of his spunk was shooting inside her, flooding her anal walls and painting them white in his color. The king enjoyed her clamping asshole as he held himself there, waiting for this pleasant sensation to pass.

“S-So, we are done now?” Luna asked after about half a minute had passed and she couldn’t feel anymore of his spunk following.

Then he pulled out and she took it as a confirmation that it was over. It wasn’t bad, she had to admit, even with the whole strangeness of having her sister’s husband or her husband’s brother inside her.

Only it wasn’t over yet.

Thorax’s horn glowed, cleaning up his dick before it quickly went to her pussy, poking it again like it did prior. Just that he wasn’t going to switch to her ass this time.

Luna’s mind was only fast enough to realize what was going to happen, her mouth unable to form words in time.

And a second later her marehood parted.

A loud pleasure-filled cry escaped her lips as she felt herself being skewered by the king’s magnificent shaft who stretched her out much more than her husband did.

She couldn’t even take it all in, her womb being already full while a part of it was still outside of her.

His tongue played along her ear, teasing her more as he was slowly thrusting in and out of her. His flat-tipped head touching her womb and pushing against it with each move. It was almost as if he was trying to slowly expand her insides to fit more snugly on his dick, instead of her husband’s.

“Good mare. Your pussy is wrapping around me so tightly,” Thorax purred into her ear, before continuing to nibble it.

Luna gave a submissive whimper, holding her rear up for him as she let him ravage her. She looked rather submissive now, moaning as she let the big changeling cock slide into her snatch, servicing it.

And it was a service. A service to the king as he was sinking in more inches as he was slowly adjusting her velvety insides to his liking. Her husband nor her sister minded it from the looks, seeming rather invested in her fornication with him.

Even more so considering how both of them changed their positions to sitting as they were either shoving a hoof up their twat or jerking their cock to the spectacle before them. It was clear as day they derived great pleasure from this. It felt a bit embarrassing as well as arousing to the lunar mare, just watching her husband and sister doing this as her sister’s husband and her own husband’s brother was fucking her like a wild animal.

Lewd slaps sounded around the room as he was getting faster and rougher. Something the dark princess appreciated. She was not made of sugar and liked it if she was challenged. And by Faust was he challenging her!

Loud squeals escaped her muzzle as her wet pussy sprayed lightly in a small mini climax as he started to let loose, another inch added to the bulge on her belly travelling deeper.

At this rate she would actually manage to fit this monster inside of her. She felt some submissive pride in that notion. A nice little achievement. Of course that medial ring going in deeper and rubbing along her most sensitive spots was a nice little reward in its own right.

The changeling king groaned as precum was flowing out of his prick, feeling himself reaching another orgasm soon. Luna blinked owlishly, wondering just how virile he had to be to still be able to pump out cum. That contraceptive spell might be a good investment from her side, but it also made her feel a pinch of regret...

“You know, you could simply dispel the spell,” Thorax suddenly whispered into her ear, making her flinch. It was as if he could read her mind.

“W-We never said anything of the sort. W-We are married,” she protested shakily as the monarch simply pressed on casually.

“But you thought about it. There is nothing wrong with being bred by me just like your sister. Your husband wants it as well. And if you are worried about public backlash, we could simply keep it a secret. There is no need to hold back if everyone here wants this, is there?”

His voice was smooth, slithery but also dominant. He wanted to breed her. To push his brood inside her womb and claim it. Her eyes flitted over to her husband, who looked approvingly at her.

“A-Ahhh! Y-You can take down the spell. Like I said, it would be an honor if my, ahn, k-king impregnated you, my wife. N-Nothing could make me happier!” he moaned out, hoof erratically beating his shaft.

Maybe she was the weird one for even hesitating now. Not even her sister protested against this suggestion. And Thorax was right, why not do it, if everypony was in favor of it.

“W-We shall permit it,” she finally breathed out, magic glowing as it did on her womb, dissolving the spell.

Then the dark alicorn grit her teeth, a muffled orgasmic scream almost escaping her as her pussy clamped down on him.

It felt different. A lot rawer of an experience without the spellwork making sure her egg wouldn’t be bred like that of a common whorse, but here she was now.

Her hooves gripped the bedsheets, tongue lolling out as the last few inches were forced inside her. She came. She could hardly stop it. This was just too good of a feeling to pull back in. She might have been looking undignified, but her mind had no capacity to care about it as his balls slapped into her.

Her changeling husband was no different, cumming on the spot as he groaned, his dick firing off his load onto his torso. A load that would never touch her insides.

It was such a debauched thought and yet she enjoyed it as the full length of the king’s member was spearing her body relentlessly.

“M-More!” she screamed as she watched her husband cum, “F-Fill us up! Breed us and show our h-husband how it is done!” she begged.

Her sister was shocked by this exclamation, while Pharynx couldn’t help but shoot out some more at her words. All the same her sister did enjoy it too, smirking as her own hoof dived in deeper, making her moan out whorishly as she was trying to push herself over the edge.

“I will Luna. I will breed you in front of your husband. Take my cum! Get pregnant with my brood!” Thorax exclaimed, groaning as he was reaching his limit.

His balls still had more than enough spunk to give, pumping their precious cargo out into her womb.

Her egg never stood a chance as it was doused in the stuff. She knew that she was impregnated immediately, her egg penetrated as her entire womb was bulging out from the sticky white baby batter he was filling her with.

Luna’s body tensed and trembled as she was thrown into another climax. She barely managed to see her sister cumming as well, her juices soiling the sheets as they were all riding out their respective highs.

Once done, Luna slumped down on the bed, panting heavily while Thorax kept his dick inside of her, his breathing more heavy as well.

“I think I finally get why Cadance wanted me to pair up with other mares,” the king voiced after recovering from the intense mating session, making Celestia chuckle.

“Are you two okay?” the changeling inquires further, while Pharynx looks at both of the alicorns as well as if to check.

“Yeeeeeeeeeeeeeeeeeeeessssss…” Luna moans with her muzzle stuck against the blanket on the bed.

“Never better. And yes, our niece does have quite the intuition when it comes to love. Then again, she would probably try to pair up any single pony if Shining wasn’t holding her back from abusing her political power.”

The changeling monarch nodded with a grunt as he pulled his dick out and set it on Luna’s ass. It was still erect, not seeming to have faltered in the slightest, surprising everypony in the room.

“...You are still hard?” Celestia asked with a twinkle in her eyes. “Maybe you could go another round with Luna then~”

“Nay...this princess is in need of a break.”

Pharynx looked between them, seemingly in thought before he spoke up.

“I can do it.”

All eyes turned to him. Shock and surprise coloring each of them.

“Eh...Not to offend you Pharynx, but I am only into mares,” Thorax said, smiling at him awkwardly.

Pharynx avoided eye contact, blushing as he rubbed one of his forelegs with his hooves in embarrassment.

“Well...that much is obvious, but you could turn me into a proper biological female if you wanted to, with the Talisman of Mirage,” he voiced, the king’s eyebrows shooting up at that suggestion. Pharynx could turn into a female with his own powers, albeit the artifact did go farther than that and would make him able to even conceive children as well as lock him into a female form with no chance of growing a dick, even while in disguise.

They did have this changeling artifact. They were about to ship it to deliver it to Twilight’s new school as a part of a cultural exchange program of sorts.

“This artifact could change you to a full-fledged female, with a functioning womb and everything. But...why would you suggest this?”

“I...I want to be of use to you. More of use to you. Those two have durable bodies, but they are not enough. Not enough to satisfy your needs and make you happy,” he pointed out, making Luna scowl at him in clear disapproval at the mere suggestion she could not outfuck him...only to remember that she did ask for a break just a minute ago.

Then Pharynx fluttered off the bed and to a safe that was built in the wall, before he could say anything. His magic reacted with it and it opened to reveal the artifact.

A small scepter with a horned bug-like head that was holding a yellow smooth oval gem. He activated it, as Thorax rushed towards him, trying to stop it, but of course was too late.

The magic was coursing through him, his form becoming lither and more feminine, muzzle getting into a cute shape, while his body rounded out. In the end Pharynx was still toned, albeit as a toned female changeling. Attractive with her longer legs and cute butt just like Luna was.

“What are you doing Pharynx! It will need at least a full moon to revert such changes!” he said, quickly getting the artifact away from his now wayward little sister.

She whimpered at the scolding, lowering her head.

“I...I just want to make you happy.”

Thorax swept her in a strong hug.

“You don’t need to change your form for me to be happy. I love you just the way you are. We are siblings.”

That line made her smile warmly, a rather strange thing to see on her.

“I guess, I don’t...but I still want to, brother. You are my king. My light. I want this. I want to serve you. In any way I can,” she told him, her hoof wandering down and gripping his dick, making him gasp. She quickly started to stroke it, making his breathing more ragged.

“There is no need to hold back. You said so to Luna and now I’m saying it to you. I want you to throw me on that bed next to my wife and use me until your cock softens. Be as hard as you want. As fast as you want. You don’t need to hold anything back with me. I can take whatever you throw at me. It is okay if you need an hour with me. Or two. Or the entire night. I will take it. I will milk you dry. Every. Little. Drop.”

Her voice was incredibly sultry and smooth as silk. It caused confusing emotions in Thorax. Here was his brother-turned-sister seducing him, almost begging him to fuck her.

How was he supposed to respond to that? How was he supposed to resist after she continued to tease his large rod?

The answer is he couldn’t.

He let out a dominant growl that made the smaller changeling mare shiver as his magic enveloped her. He walked over with her in his grip, slamming her body belly first onto the bed, right next to Luna before getting on top of her.

Pharynx was a bit disoriented by this, not even having any time to react before her newly formed pussy was deflowered.

She moaned out. Her pussy was split open by his massive cock. It easily penetrated her virgin womb on the first try, fucking her hard and roughly, his hoof pressing against her neck from behind and pinning her to the bed dominantly.

Thorax grunted, her pussy might as well have been a vice with how tight it was. But it was rather pleasing all the same. He could even feel his now sister’s walls clench around him periodically as if to deliberately service him and milk him of his seed.

It was as if he was encouraged to do her even harder, so he did. While he did only slowly stretch Luna out to fit his cock, he didn’t take such care for Pharynx, though considering the moans and squeals she was muffling with the bedsheets it didn’t sound as if she was protesting at all.

Her hooves certainly gripped the sheets tightly and her legs were spread, as she was holding her position like a champ. It wasn’t even a minute before the large outline of the king’s entire dick bulged out from her body as he was inside her balls deep.

The artifact really did change Pharynx completely. A perfect transformation with all the functioning equipment one would need to copulate, or fuck like animals in this case.

Strangely enough said artifact was normally well secured and yet it was ready at a moment’s notice...

It was then that Thorax realized something.

“The artifact was locked away, and yet you had it here in a safe. You planned this all along didn’t you?” he asked, words laced with lust.

“M-Maybe, a-ah! Ahhhhhhhnn!”

“Who would have thought that I have such a slutty sister~ You were just fantasizing about getting changed permanently to a girl this whole time. Did you want my fat cock that much?”

“I-I d-diiiiiiiiiiid!” she cried out, a spray of juices gushing from her cunt and bathing his balls in her arousal as she came. Her body arched as she bit into the sheets, trying to muffle the sound. Or as much as she could with her brother pinning her neck. But even with this, his strong brother wasn’t slowing down. He was fucking her right through her climax, hammering her spasming cunt like she was a two-bit-whore.

And like a two-bit-whore Pharynx came again from this immediately.

Wave after wave of pleasure came crashing down on her mind, her eyes rolling in the back of her head. Then after arching up, her body slumped again, head sinking into the soft bed with her tongue hanging out goofily. There were even some tears leaking from her eyes from the sheer overload of ecstasy and lust that her king was bestowing upon her.

She knew she did say she would take him for however long he pleased, and she still intended to do so, she just wasn’t sure if her body could actually hold up on that without passing out in the middle of it.

Her brother’s muzzle came down to her ear, his husky voice sending more shivers down her spine.

“You are a naughty sister, Pharynx. I don’t even wear a condom, you know? If I came inside you and bred you like you slut deserve, you would be trapped in this form until you gave birth. Is this really what you want?”

The last part sounded as if he was asking for permission from her. Just to make sure that she really wanted it.

She responded without hesitation.

“Y-Yes my king! B-Breed me like I’m one of your concubines! A common skank and cocksleeve for you to use to satisfy your every sexual need, aah! A-aahhhh! H-Haahhhnn! D-Don’t stop, e-even if I pass out! O-Only once your balls are c-completely emptied inside me!”

Thorax’s shaft throbbed hard inside of her at that slutty exclamation. Even if she would have changed her mind, he couldn’t stop anymore at this point.

His hips accelerated, becoming a blur as loud wet smacks echoed through the room. He felt himself getting closer. Too close. He was going to impregnate his little sister. Well, technically big sister, but with the size difference and gender change she gave off more of a little sister vibe. And now he was going to breed her and make her carry his foals!

No holding back. Just pushing it all in and claiming her as his own, just like the other two alicorn mares.

Loud groans escaped his lips, precum flowed freely from his rock-hard horsecock. His sister laid delirious beneath him, only giving pleased noises by now, not able to speak with how hard he was jackhammering her.

And then he exploded inside her. His load firing off and instantly stuffing her once so tight virgin womb, packing it with his virile sperm and flooding her egg, effectively breeding her like with the others.

She was done, cumming and trembling on his glorious royal cock as belly bulged out, screaming into the sheets in pleasure as she got exactly what she wanted.

It was all over soon, Thorax relaxing and laying on top of her body, the cool carapace feeling nice against his own.

“...That was intense,” Luna noted, by now laying on the bed next to her husband-turned wife and peeking at her curiously.

“Not how I was expecting the night to end, but I am not complaining. It is a rather fun exchange,” Celestia mused as well, giggling a bit as she looked at the pleasure-drunk sibling pair.

“I-I had no idea about this either. But I will take responsibility for it. I am sorry Luna. I will make sure to please you as much as you need.”

The dark mare waved a hoof dismissively. “Tis fine. We personally find her quite cute and are curious what else we could do in the bedroom with this new development.”

Thorax gave a grateful nod at her understanding nature before looking worriedly down at his sister.

“Pharynx? Are you okay?”

Surprisingly enough the small changeling bucked her hips, throwing him off in response as he fell out of the bed and on his ass. Pharynx followed turning around and jumping with her pussy on him immediately with a reprimanding look.

“Y-You are still hard! You only get to stop after your balls are emptied! Sheesh, a king needs to fulfill his duties, you know? So push it all inside me. Fuck me. Fuck your little sister stupid if you have to, just as long as your balls are emptied,” she scolded him harshly, before her muzzle darted forward, silencing him before he could say anything.

He growled, his tongue invading her mouth. It was as if he was accepting of her words, or at the very least rather aroused by them. He stood up on his hindlegs, his hooves gripping her ass before quickly fucking her into a wall, showing his dominance to her once more.

The changeling girl gave a distressed mewl as her back slammed into the dark wall, her legs wrapping around his hips as Luna blinked owlishly at the scene.

“...He can still go?”

Her sister giggled. “He does. You know, I think marrying these was the best idea I had. I believe we have many pleasant days ahead of us.”

The lunar alicorn nodded, before grinning. “And he seems to be able to take care of us all as well~”

She quickly jumped and fluttered to the ground, getting behind the changeling king and down, as her mouth quickly latched on to one of his balls, suckling it. She threw a look back at her sister who shook her head in amusement at her antics.

“Well...there is still one ball in need of service,” she mutters, slowly standing up and hopping off the bed before joining her sister beneath the large king and latching onto his free orb, suckling it as he groaned and rammed his sister.

This was the start of a long and debaucherous relationship.

- 7 Months Later -

Some time passed since the marriage between the pony and changeling royalty. And while some eyebrows were raised at Pharynx's new form, it was something either side got used to very quickly. Changelings, because they are used to changing forms, and ponies, since they assumed it was just something changelings would do normally with their innate abilities.

The relations between the nations and their citizens also improved just like planned and more changelings moved to Equestria. It was their main home after the honeymoon was over, seeing how Equestria itself was the larger nation.

Not that the king and now changeling princess minded. They even made plans for a hive that would be integrated on Canterlot, expanding the city limits and giving changelings and ponies some room to mingle. It was getting close to completion now with many areas already in use and many more ponies getting ‘friendly’ with their new neighbors. A cultural exchange that deepened the bonds even more than what even the royals had foreseen. A good development that only seemed to sweeten their days together.

By now both of the alicorn sisters and the changeling princess were highly pregnant with Thorax’s children. And they were quite healthy too from what the doctors said, meaning that they would have many new little royals running around soon. They could hardly wait to give birth to them. Pharynx especially seemed giddy for it to happen.

They were taking a break currently from the busy day, walking the path along the royal gardens for some R&R. Thorax of course was in the lead with Celestia to his right and his sister with her wife to his left.

The dark alicorn looked the changeling princess over thoughtfully.

“Are you sure you are happy with this? We could always reverse the changes as soon as birth is given,” she pried, caring for the mare’s well-being. Even despite the gender change, their relationship didn’t change too much. Aside from how they were laying on top of each other as Thorax rutted them silly regularly.

“I’m the happiest changeling in the world!” she insisted, pride-swelled chest pushed out, which made Luna chuckle. She had to admit...her wife looked cuter like this. So maybe it was indeed not a bad thing.

“And you get rutted by your kind and brother regularly instead of rutting me,” she further noted with a little giggle.

“...How is that a bad thing?”

Yes. Her wife was indeed cute in that oblivious way.

“We guess it is not. Tis’ like thee says, it is an honor to carry such a strong king’s offspring.”

Pharynx nodded fervently.

“Besides, I get to be shafted by him together with you. There is nothing that makes me happier than to be with the mare that I love.”

“D’aww!” she voiced in delight, nuzzling the mare's face as Thorax and Celestia looked at them in amusement.

By now they reached the spot. A nice little pond where they had a blanket laid out for them, Thorax resting with his back against a tree as Celestia and Luna snuggled to his side. He did put a hoof around them and on their bellies, caressing them. Pharynx seeing this pouted as she instantly dived on top of him. The weight surprised and pushed the air out of his lungs for a moment as he chuckled, nuzzling the top of her head as he felt her swollen belly pressing into him.

He sighed out, enjoying the warmth of their bodies as well as the slight breeze on this sunny day.

“I think this is truly the best outcome for all of us. I consider each of you my wife and can’t wait for you to give birth to my foals.”

“Not the last foals either,” Pharynx insisted. “I want you to breed me again and ensure your lineage spreads far and wide.”

“Don’t get ahead of yourself now. First things first. After the birth we can see about broadening the family some more,” Celestia tutted at her, smiling at Thorax who smiled back.

They stared lovingly at each other for a moment before the white mare pushed her muzzle up and kissed him. Thorax enjoying the warmth of her lips, only for her to swiftly get shoved aside as a darker muzzle replaced his wife’s. His sister didn’t want to be left out apparently.

“Sharing,” she stated once she pulled off. She then threw her wife a meaningful look.

Luna rolled her eyes darting her muzzle up to his lips, while Celestia snorted.

“You should remember who’s husband you are kissing, sister,” she threw in cheekily, darting her mouth forward as well. Pharynx gasped indignantly and joined as they were having a four-way kiss with him, Thorax moaning at the sensation of their love and...lust?

He could see the smoldering look of his sister as she was humping his sheath, her wet love juices smeared all over it. This teasing sensation made his dick slowly slip out and glide across her wet folds.

They might have to expand the break at this rate.

“I love you all,” he moans out through the kiss just as Pharynx was lining up with his shaft as the others moved in closer to him, making his hooves slide over their backs and to their asses before ending up at their folds. Rather soaked folds.
