Thorax needs to marry the Royal Sisters to ensure the safety of his citizens. Luckily he has some changeling tricks up his sleeve to coax them right into this agreement. Lots of Maledom ensues.

King Thorax is leading a completely new nation. This comes with risks and dangers. So to protect his subjects he and his brother need to marry the Royal Sisters. Of course such a thing is quite a daring strategy. Especially since for all intents and purposes those two are known to have never been in any relationship in all their lifes.

Royal Sisters on the Negotiation Table

Author's Note

This story was split into two parts at the recommendation of my Editor. This is the one with the Dubious Consent with the Princesses.

The Eventual Consensual Rape with Genderbending follows after.

Royal Sisters on the Negotiation Table

“I thank you both for taking your time to meet with us,” Thorax said as he and his brother Pharynx were greeted by the celestial sisters inside a large meeting room. The alicorns hereby meeting them right at the door, smiling at their fellow rulers.

“You needn’t worry King Thorax. We understand that as a new foreign nation you would have lots of questions and agreements that need to be addressed,” Celestia wisely stated as she shook hooves with the tall changeling. She found that he was even a bit taller than herself. A welcome change for her neck that normally always had to bend down to look at others.

Celestia then elbowed her until then silent sister, giving her a look while also pointing her head towards them.

Luna sighed, reaching out her hoof to Pharynx, “Ah, yes. Pharynx I presume?” As she said this her tone was a tad icy. “I think we have met before.”

The changeling looked at her neutrally as he accepted her hoof and shook it firmly.

“I remember. You were rather heavy to carry back to the hive after I knocked you out before my brother took over.”

An awkward silence permeated the room, Thorax laughing nervously, while Luna glared dangerously at the dark changeling.

Celestia herself grimaced slightly as she quickly laid a wing firmly on her sister’s withers, trying to stave off her clear hostility.

Pharynx himself only looked around confused, “What?”

“Ahem! I believe what my brother wants to say is that he is VERY SORRY for any past actions the changelings have committed against Equestria,” Thorax quickly stepped into the room bowing his head demurely, and making Pharynx snort.

“Grow a bucking backbone brother,” he muttered, while Celestia decided to ignore him, lest they start this off any more on the wrong hoof than they already had.

“It is all forgiven and forgotten. You proved yourself and changed your ways for the better. And none of us holds any ill will...Right sister?” she asked the last part insistently, with a sideways glance fixed at said darker alicorn.

She harrumphed, “Right...sister.”

Celestia smiled, sitting on her plush flank and clopping her hooves together in approval.

“Very well. Now let us take a seat and start this meeting. You initiated it, so there is quite a few topics you probably want to cover.”

With that said Celestia led them to the table, Luna following begrudgingly behind. Soon enough the sisters were seated on one end, while the changeling brothers were seated on the other.

Thorax nodded, “There are a few topics. First of all I am interested to keep my fellow changelings safe, albeit with a history such as ours I fear for this safety. Other nations could try and declare war on us after this leadership change, seeing a weakness and vulnerability in our new way of life and using past crimes as justification. So, we need protection. A clear communication that Equestria is our ally.”

Celestia started to pour Thorax a cup of tea as he explained, nodding along. It made sense. Their reputation breeds hostility. So a strong ally could not only deter attacks on them but also assure the other nations that their change is genuine and not a trick.

“I fully understand, and I assure you, King Thorax, that you have our full support,” she offered with her well-practiced smile at him. Still, she couldn’t help but notice that he looked nervous, his gaze wandering to his brother who nodded. The ruler of the changeling kingdom then sighed, taking some breaths in and out, seemingly relaxing.

‘He is actually rather cute like that. Not to mention his strong well-formed body build… What am I thinking? Celestia, you overzealous mare, you shouldn’t have such thoughts about foreign leaders! Though it would be a lot easier if sister shared such a more positive line of thinking,’ Celestia hummed as her eyes gazed slightly to her right, only to see Luna turning her head, as if trying to not acknowledge them.

Thorax cleared his throat a moment later, drawing her gaze back to him.

“I thank you Princess. In all actuality... there might be something we would like you to support…” the King explained fidgeting in his seat.

Celestia giggled at this, ‘Cute.’

“And what can we offer you?” she inquired, her head leaning further in.

King Thorax again looked to his brother, who seemed really annoyed by now. Another sigh from the King followed.

“Well, you see… We came up with a way to effectively protect our subjects. This measure being...you two marrying us…”

All was still for a moment. Celestia kept staring at the changeling King with the same smile, albeit she felt the corners of her mouth twitching.

‘Eh?’

Her sister on the other hoof was a lot more articulate.

“T-This is OUTRAGEOUS!” Princess Luna roared, heavy winds lashing at the two changelings from her voice alone. “Just to THINK some filthy BUGS want to taint our PURE bodies is sickening beyond belief!” She was now standing with a slight blush adorning her cheeks. Her hoof then came down on the table splitting it in two and spilling the tea over it.

Pharynx stood up, not in the slightest intimidated.

“If you want to have a rematch from last time, I’m more than up for it. But don’t faint in the middle of it like last time,” he taunted with a feral grin, showing his fangs.

Luna flared her nostrils, her head lowering and her horseshoe clad hoof scraping on the floor menacingly. Pharynx instantly mirrored her stance, seeming quite elated.

“SISTER!”

“BROTHER!”

Before they could get to it however, both were encompassed in a magical aura each.

Both of the troublesome siblings seemed disappointed by this, but stood down for now, knowing they couldn’t do much with their co-rulers in the way.

“I truly must apologize for my sister. Her behavior is unacceptable. Even more so the words she said about your race. She really didn’t mean it and just overreacted from the...surprise of your idea. I hope you can see past this,” Celestia said, trying to be the voice of reason here. She definitely didn’t want to alienate such a close potential ally. However Luna seemed to think differently.

“I was just trying to squash some troublesome bugs,” the Princess of the Night muttered before the aura tilted her down and dissipated, making her fall flat on her face.

“Oh my! How clumsy of me!”

Luna stood up, glaring fiercely at her sister but said nothing.

Celestia put on her pristine smile, her magic repairing the table and tea set in mere seconds.

“Now, that this is out of the way...maybe you could...rephrase your proposa-, I mean suggestion!” Celestia corrected, blushing slightly as well. Much to her own chagrin she could even feel her pussy tingling slightly.

‘O-Oh dear. Is it getting hot in here?’

As she resisted the urge to fan herself with her hoof, Thorax sighed.

“It is as I said. I’m asking for your hoof in marriage, as is Pharynx asking for Princess Luna’s hoof in marriage.”

“Oh…” Celestia simply stated, her eyes instantly flicking to her sister in worry and her horn preparing to light up in a moment’s notice if she had to. Luckily her sister simply glared at the two.

“Denied! To even think to propose this to us… You do have a lot of guts,” she ended a bit unceremoniously, turning her head and crossing her hooves as her small-flanked plot squirmed in its seat with a blush on her cheeks.

“I do have to join my sister in her perspective here. While we certainly do feel...flattered to have such well-looking suitors-” Celestia said, quickly stopping and blushing at her words, before doing her best to ignore the embarrassment and press on, “-we can’t accept it. While I might be a spontaneous mare, marriage is a too far-reaching decision to make for us in a flash.”

“But that does mean there is a possibility. Right?”

The Sun Princess grimaced. “U-Um...I mean that we would only marry once we find our one true love. Something like that cannot be easily achieved,” she replied diplomatically before her magic reached for her teacup, having the desire to quickly swallow some of the soothing tea to calm down again.

Pharynx took that moment to speak up.

“In other words, they are virgins. Both of them.”

While Celestia did a spit take directly at Thorax before coughing violently, Luna had a much different reaction. She practically pounced over the table and on the offending changeling with a loud battlecry. Sadly she didn’t get too far as he rammed his hindlegs into her stomach, throwing her behind him.

Just before Luna could right herself from her position on her back Pharynx was standing on her legs, pinning her to the ground.

He grinned, his head coming closer to hers, “Feisty. I like that.”

Luna’s head exploded in a blush and her own marehood ejected some of her marecum as a shiver run down her spine from this changeling’s predatory stance. The Princess of the Night didn’t know what was happening, but she felt some excitement at her situation.

But much to her surprise he let her go, turning around and swatting her snoot with his tail. Luna’s nostrils flared at his smell, and her eyes got a good view of his black dangling changeling orbs.

She bit her lip as she stood up as well, her tail tucked between her legs to hide her moist slit.

As Pharynx sat back down Celestia has calmed down again, her coughing ceasing as her sister also took place at the table again.

The Princess noticed that pouncing, but was glad it got resolved before she had to intervene. Honestly, she was rather impressed by Pharynx. None of the guards would have so easily been able to pin her combat-experienced sister. It certainly confirmed Celestia’s thoughts of their peak physical conditions.

Though she had no time to dwell on this as she quickly used her magic to teleport a towel to her location for the drenched Thorax. She felt rather sorry for her poor showing of manners.

“I must apologize. Here. Take thi-” she wanted to say, but a fire encompassed the changeling and a second later he was dry again.

“It’s alright,” he simply stated, making Celestia feel foolish for forgetting this possibility.

‘Where do you have your head stuck today Celestia?’ she chastised herself as she put the towel away.

“I’m sorry about my brother’s remark, though...he still has me quite curious too. Are both of you still virgins?”

Princess Celestia felt another surge of embarrassment swell up inside her chest as her marehood heated up as well. Somehow this question filled her with anticipation. And for some reason she didn’t want to refuse the answer...

“We are!” Luna suddenly exclaimed loudly, her eyes fixing on Pharynx. “No pony is strong enough after all to tame us!”

Pharynx leaned his head forward at that, flashing his fangs again, “No pony. But a changeling.” After he stated this he licked his lips, making the Princess of the Night tremble slightly as she suddenly shyly avoided her eyes.

“A-A Princess would never stoop this low,” she said, trying to use her bravado, but instead her tone was anything but.

Princess Celestia couldn’t help but raise an interested brow at her sister, who upon noticing this pouted.

While the chance to tease her sister was rather tempting, Celestia held it back. She had to get this disastrous meeting back on track.

So she lightly coughed in her hoof to get the attention back to herself.

“We both are virgins, which is why we take the topic of marriage even more serious. Both of us want to fall in love with somepony...or creature before we can even consider something like that.”

“Well...how do you know you won’t love us?” King Thorax countered, making Celestia stop for a moment.

“Um...we don’t? I mean...it isn’t so easy to determine…” the Sun Princess said, now not quite sure how to respond.

“Then it means it is possible. You only would have to give me and in Princess Luna’s case give my brother Pharynx a chance.”

In that moment the darker alicorn squeaked in her seat, making her sister turn her head towards her. Luna was glaring fiercely at Pharynx, a low growl on her lips.

“Y-You-!” she stammered, her hoof pointing threateningly towards him.

“Is something wrong sister?” Celestia asked with some confusion.

“There is only something wrong if she is a coward,” Pharynx stated with a cocky grin that halted the other alicorn for a moment. The wheels in her mind clearly turning and trying to decide how to react. Her eyes stared deeply into the other changeling’s before she finally snorted and lowered her hoof as her hindquarters rubbed along the seating pillow.

“E-Everything is fiiiiiine!” she affirmed, with a slightly higher pitch in her voice.

“Oh, um, if you say so?” the older sister replied, not noticing the slight glow on Pharynx horn. Instead she went back with her gaze to Thorax. He seemed like a rather nice changeling. And he was also rather easy on the eyes as well…

“Anyway...I can’t rule it out,” she admitted. “So...maybe we could arrange more of those meetings to get to know each other better. Right...sister?”

She looked at the dark alicorn, noting her heated labored breathing as she seemed a bit dazed.

“Luna?” Celestia said nudging her with her wing.

“Oh, um, y-yes! I’m not going to marry some bug without some more time to enjoy-, I-I mean, spend more time with first!”

“This is taking too long,” Pharynx stated, standing up. “Our nation is at stake, after we risked everything to save yours from the rule of our prior Queen. We don’t have any time to play games and drag this out.”

“Brother,” Thorax started but Pharynx cut him off.

“No. They owe us. And beating around the bush any longer won’t help us any. Think about all the changelings that are counting on this alliance to work.”

Thorax fell silent at that as his brother took over for him. The smaller changelings eyes were fierce, making a shudder run down Celestia’s spine.

“We demand your and your sister’s virginities as well as the right to breed some strong royal changeling offspring into your wombs for saving Equestria.”

Another silence started, but this time Luna didn’t jump in, leaving Celestia with the uncomfortable and rather outrageous demand.

‘Why can’t you just bowl him over again Luna?’ Celestia thought as she did her best in her flustered heated state to compose herself, ‘It is almost like I’m in hea-’

A realization struck her at this very moment, making her blush intensify.

‘Buck.’

It was a simple thought but expressed her situation so well. She couldn’t just excuse herself from the meeting. It was way too important for that, meaning she was stuck with these urges until she managed to come to a consensus with them, something that seemed next to impossible now that Thorax’s brother suddenly took over the negotiations.

Still, this heat was rather early. Three weeks too early. With her experience she could predict her cycle rather well, and yet she felt nothing in the morning. It was a rather strange occurrence, though she hardly could dwell on it right now seeing as she had a foreign leader right in front of her nose. A rather good-looking foreign leader who offered to pound that by now soaping pussy of hers like there was no tomorrow…

‘Bad thoughts.’

She laughed nervously, trying not to think on her wet nethers as she had to press on.

“I-I’m sure there are much more feasible ways to resolve this. I mean technically, it was your Queen that endangered Equestria in the first place.”

“So our achievements mean nothing?”

“I-I didn’t mean it like that. It is just a rather high price you are asking for.”

“Meaning the lives of your subjects weigh less than nothing compared to your own purity.”

“W-Well, your subjects! They wouldn’t even profit from this!” Celestia pointed out, clearly slowly getting desperate in an attempt to steer the topic away from her marehood.

“Royal Changelings would be a reason to rejoice and expand the social security of having a stable and growing leadership.”

“What about...about...our reputation! Yes! If we get seen pregnant-”

“You got spells to hide it if you really are concerned about this.”

“S-Still, a pregnancy is a bit much,” she feebly argued making Pharynx groan.

“How about a deal then, we only take your virginities and right before we cum, you can decide if you want to take our load or not.”

“Well, that...sounds...reasonable…?” Celestia answered awkwardly.

‘What am I agreeing to?!’ she screamed a moment later in her thoughts, her mind filled with panic, fear, but also excitement and lust. She could practically feel how strong this heat was going to be and her hooves certainly won’t do it for her. ‘As if that is the problem! If I have to I can just lock myself up in my room for a day to take care of it. But doing it out of a whim with other foreign leaders, doing it with Thorax...’ Her eyes wandered to said changeling who smiled at her brightly, making her heart leap. ‘Might...not be so bad? No! I need to...Luna! She would have to agree for it to count! So I can back out on this if she just-”

“And you little changelings really think you have a chance against the Night!” the darker alicorn exclaimed standing up proudly, albeit her hind legs were wobbling slightly. “You can try and take your price if you manage to overwhelm me!”

“Sounds like this braggadocious pony is agreeing with the agreement, doesn’t she brother?”

Thorax nodded, “She does...in her own way at least. So I guess this reward is decided on then.”

Before the King even finished his sentence Pharynx already was stalking towards the prideful dark alicorn.

Luna couldn’t help but grin, as she lowered her front slightly as if in preparation to take him on, though that fell short as he simply intensified the glow on his horn, making some buzzing grew louder as well as a certain glow grow. Luna whinnied, her stance faltering and Pharynx used that opening instantly to ram into her body.

The Night Princess toppled to the ground again, but instantly did her best to show some of her own dominance, swinging her hoof at the changeling. He simply swatted her hoof away, his hard chitin clacking against her hoof. Then she tried to move her other hoof but Pharynx leaped forward and into a kneeling position right on her forelegs, albeit what really distracted Luna were the pair of changeling orbs suddenly resting on her chin, among...other distractions.

“I-I’ll get you next time!” Luna vowed, before moaning and it was then that Celestia saw it. A glow vibrating along her sister’s privates. Pharynx’ magical aura had enveloped these parts, at one point even seeming to have gotten her clit in its grip, forcing it to stay outside as the dark changeling pulled on it, making the Princess whine. Her slit and thighs were completely drenched. The older sister could even see a slight wet trail from the wet spot of her sisters seating pillow to her position now, indicating this had been going on for a while.

It honestly shocked the experienced ruler, to see her sister like this, making her mouth go slack as Pharynx humped his balls into Luna’s face completely unashamed.

“You are welcome to try,” Pharynx meanwhile teased as he rubbed his musk onto the younger Princess’ face. “But for now you lost, which means we are going to have some fun. You after all agreed to it. And as an honorable warrior and Princess you wouldn’t go back on our agreement would you?”

“I-I will of course honor it! Y-You filthy bug should feel honored though! To even have my permission to do such dirty things to me!” the Princess belted out in another show of false bravado, that quickly turned to nervousness again, “P-Pray tell, how do we start this?”

“It is rather simple. First you are going to suck my fat changeling cock to prepare it before I rob you of your virginity. You got that pony slut?” he growled at her before he allowed his arousal to flow through. Within a second his cock sprang forth from his sheath showing off a thick slab of horsemeat that suddenly rested on her face.

The mare gasped in delight, her nostrils taking in the thick salty smell of this organ as she felt it pulsing on her head. Her lips were a mere inch away from his majestic tool as she tried to take it all in with her eyes.

Pharynx certainly liked the awe-filled reaction to his impressive length, but still he had enough of the waiting game by now, so he lifted his hindquarters up and angled his shaft right at the Princess’ mouth, dangling it directly over it.

Luna for a moment felt a bit of apprehension as she recalled just what he asked for. It wasn’t exactly part of the deal and looked rather big too. Still...there was this nagging at the back of her mind. She knew she would come off as a coward if she started to protest now after he wrestled her to the ground yet again. And the Princess certainly didn’t want to develop a reputation as a sore loser. Even less in front of this bug. So, there was only one real answer for her.

She opened her mouth as widely as she could.

Pharynx grinned, accepting her invitation instantly. He pushed passed her sexy blue lips and passed the entrance of her throat in one push, stopping only when his balls hit her chin.

While Princess Luna gagged in surprise, Pharynx groaned out in satisfaction as he felt her muscles clamping down on him.

“Not bad little Princess. Nice throat movement. Maybe I underestimated you after all.”

While Luna was tempted to try and throw him off, his words still reached her, tinting her cheeks. She felt flattered as it stroked her ego and made her cocky side flare as well. So she tried her best to hold still while also duplicating the thing that he had complimented her for, albeit it was rather difficult for her to understand in just which way she could use it. Though before she could dwell on it, Pharynx pulled already back until his tip rested on her tongue, the Princess moaning out at the interesting taste of his member. Then a moment later he shoved it back inside in one fellow swoop.

Luna gagged automatically, and this contraction also made Pharynx groan again as he got into the nice sloppy facefucking he was giving this prideful ruler. It took about ten more thrusts before she caught on, experimenting and trying to purposefully milk his delicious rod. Already she could taste his pre on her tongue as Pharynx indeed seemed to enjoy himself, something that Luna found some pride in. It started to get even better as Pharynx started to reward her for her actions. Each time he felt her throat contract, he pulled, twisted and pinched at her sensitive love nub, while increasing his vibrations on her cunt.

This wet rhythm continued on as drool and pre was smeared all over Luna’s face, running along her neck as well as into her mane while her own privates leaked profusely on the ground.

Luna felt never so great in her life. Masturbating by herself didn’t hold a candle against having her marehood and needy mouth violated by a strong strapping changeling soldier.

She embraced his cock fully, slurping on it noisily as her hips bucked up, trying to gain more pleasure from the magic that was oh so sweetly torturing her in the best of ways.

Long forgotten was the meeting as she was only thinking about his mighty cock.

And then she came.

Her pussy squirted like a needy teenagers, staining the carpet in the room with its spray. Her hips bucked even more violently, trying to experience more and more of this blissful sensation, at which moment Pharynx indeed did grant her more, increasing the vibrations and letting his magic edge into her cunt while he twisted on her clit.

“Now take it you pony slut! Feed on my changeling spunk!” he roared out merely a second later before he reached his own high, his fast thrusts suddenly ceasing after he slapped his balls into her face one last time. Then, as he groaned, he let loose his seed, making it spurt deep into her throat and letting it fill her belly straight up.

As soon as he was done, he sighed out, pulling his leaking meat out of her mouth. It dribbled some last droplets of sperm onto her tongue before it was freed from the blue lips of the Princess with an obscene pop.

The changeling then stepped back, sitting down in front of her, panting a bit. His magic having since then vanished from her cunt, letting her have a short respite.

It was at this moment that he looked back smugly at Celestia herself, who had witnessed this intense carnal bout of facefucking. And it certainly didn’t leave her unaffected.

Her face was just as red as Luna’s and her breathing had gotten a lot heavier as well. One of her forelegs was in midair, as if she was tempted to masturbate, but she held herself back still, despite the situation already having escalated.

Celestia’s mind was in turmoil. Stuck between dignity and lust. And it was in this moment that Thorax sat down beside her, taking her hoof in his own.

The mare was surprised, looking up at him as he smiled at her. She instantly avoided his eyes, feeling embarrassed.

“There is nothing to be nervous about,” he soothed, slowly pushing her hoof to her marehood. “I promise you will enjoy yourself.”

With that her hoof made contact with her snatch, Celestia instantly moaning as it wedged into her cunt slightly.

Thorax then moved it with his own, making the Sun Princess rub herself. It was a beautiful moment for her, but still, she felt a tad jealous over the dominance Luna had experienced. She pushed that thought down as she felt Thorax move behind her. She quickly leaned her back into his smooth carapace letting him masturbate her. But it wasn’t as good as it could have been in her mind, so in the end she retracted her hoof. Though before Thorax could ask her about it, she pushed his hoof to her pussy before letting it go, the message clear.

Thorax smiled excitedly as he started to rub his hoof against her folds, enjoying the sticky fluids gathering on his hoof. Liquid love like this after all was something that still made changelings energized.

The new smoothness as well as the distinct cold of his appendage made Celestia squirm into his back as she pushed her pussy in the direction of his hoof. The encouragement was well received as he put some more pressure into it, handling her a bit rougher.

Her pussy winked by that point, her clit excitedly showing in regular intervals as her pussy was played with. It was such a simple but incredible feeling and the Princess felt herself getting closer, the pleasure slowly mounting. However, shortly before she could reach it she got distracted.

*THUMP*

Pharynx who had the Princess of the Night gathered on his back had walked over and loaded her belly up onto the table, her legs dangling over the edge.

“If you are taking that long I will just take what is mine,” he retorted, looking at them annoyed as he slapped his cock on Luna’s marehood, making her whinny blissfully.

The dark pussylips were winking as the sheath laid on them, the mare obviously quite eager to feel what a real cock would be like in her virgin pussy.

“Well, the Princess obviously isn’t as comfortable yet, so I’m just trying to help her out!” Thorax protested, miffed at his brother’s rude attitude.

“Keep telling yourself that, brother, as your dick stays where it is, useless in its sheath,” Pharynx simply retorted.

It was something that irked Celestia a bit. While she agreed at this point that Thorax could be more forward, his brother shouldn’t be as rude about it. So, she wanted to reward the King. Show him that she did appreciate him and that he deserved to feel good too.

With that she broke loose from him, standing up.

“I’m ready now,” she declared with confidence.

The King grinned, looking over in triumph to his brother who simply rolled his eyes.

“If you like pity sex,” he muttered annoyed.

Pharynx though was ignored as Celestia took Thorax’s hoof, leading him over towards the table.

“Please lay down. It is only fair,” Celestia said, softly pushing him with his back on the table.

His head craned up, watching her with interest as she climbed on the table as well in a sitting position right over his balls.

He could feel her hot sticky marecum trickle from her marehood directly onto his eager orbs as she positioned herself a bit confused on how to best start this. Or more accurately, how to get his cock out of his sheath. Though that problem was solved a second later.

The hot juices raining down on his balls were stimulation enough to make the King hard within a second, his long thick prick of dark green horsemeat standing proudly and making the Sun Princess gasp from surprise.

“I-It is so big,” she mumbled as her eyes took it all in. Her gaze gleaning over every curve, and every vein. She gazed upon the big medial ring and the large tip.

‘E-Even bigger than his brother,’ she noted, although it made sense Thorax’s tool would have a bit more girth and be taller seeing as he was the bigger changeling of the two.

She was so mesmerized she stared at it for a full minute before Thorax coughed, making her eyes follow up to his and renewing her blush.

“I-I apologize. Your size just...surprised me.”

“It is quite alright. Though we should slowly move on. Pharynx is getting a bit impatient.”

The changeling in question immediately retorted. “Damn right I am! I have this wet pussy eager for my cock, so I don’t want you two to take forever.”

It was then that Luna piqued up again, seemingly a bit more coherent after this little waiting period.

“Y-You should be grateful a bug like you is even allowed to touch it!”

“Oh? So what? You pony sluts would be fine if I just turned around and looked for another mare? Bet I could easily pick up a guard mare and show her just how good my fat cock feels.”

Just as he wanted to pull his hips back, the mare’s hindlegs locked around him, a slight panic in her eyes.

“Good,” Pharynx said humping his cock over her marehood, heating it up with his teasing thrusts, “Here is how we will do it. You are the one who is going to be grateful. Grateful that we changelings changed our ways and grateful that I’m even considering fucking you right now, instead of your plush-assed sister.”

A short bout of silence followed, making the changeling lean closer to her face with a growl.

“Speak up slut.”

Luna avoided his eyes but Pharynx used his magic to force the mare to face him as he awaited her reply.

“I-I...I would be...grateful...i-if you shoved it into me deeply.”

“Was that so hard?” he said in a belittling tone. Luna wanted to retort but was cut off quickly as she felt the changeling’s hard rod parting her lips.

A surprised squeal escaped her as her marehood was for the first time in her entire life stretched wide open by this perfect piece of changeling anatomy. It was thick, it was strong, and most of all it was insistent, drilling deeply into her until his cum-sloshing balls slapped on her petite ass before pulling out and instantly sinking into her to the hilt again.

The Night Princess could do little more than cry out as nerves were stimulated that never were touched before as the rock-hard cock was scraping against them violently.

“B-By mother! I-I never felt like this! H-Harder! T-Thine Princess needs it harder!”

Pharynx growled, pumping his cock extra hard into her, making her squeak. Then as he was buried completely into her, he stopped.

“Don’t even try to pull your title on me pony slut. Or have you already forgotten who the one is that needs to feel grateful?”

The mare withered under his intense gaze, but at the same time felt excited about it and the dominance he was asserting over her.

“A-Apologies!” Luna squeaked out, amusing the larger changeling.

He then simply huffed before getting back to thrusting into her slender frame as his eyes wandered over her body. He certainly could appreciate her toned form. Even her small butt had its own allure. She did look like a fighter, so he certainly had no qualms to fuck her just as hard and mercilessly as a fighter. Not that she was complaining. If anything, she was moaning harder.

She certainly would be rather easy to prey upon now.

“You better get used to the fact that this will be your only time feeling my cock. After all, I won’t just come here and fuck you again because you little slut demand it. You only would have a chance to get my cock daily if you were my submissive wife.”

The moment these words left his lips, her eyes turned to pinpricks, her hazy mind restarted as this piece of information sunk in.

‘Only once...I-I could really never feel it again? S-Surely he jests?!’

“B-But you can come here on visits! Y-You truly wouldn’t pass up on the opportunity to feel my royal folds again!” the mare asked desperately, her legs hooking against his backside tighter.

Pharynx meanwhile looked down at her, his eyes a simple deadpan, “I will pass. I’d rather try some other virgins around Canterlot. After all, why should I care if you aren’t even my wife. So don’t expect me to be some cheap booty call for you.”

The Princess bit her lip as Pharynx simply continued to hammer into her pussy, seemingly not interested in hearing any more and just concentrating on his reward and pleasure.

Luna’s mind grinded to a halt, the weight of this decision she would have to make clear to her, but just as clear was the incredible pleasure this changeling was gifting her with. The latter got even clearer once she started imagining what agreeing to take him as her husband meant. Her mind went to different scenarios, to sparring, followed by being pinned down and fucked. Lunch, and having to suck his tasty cock under the table while nobles were in the room. The nights when she would lower her front and let him go at her so much she would pass out from the sheer bliss his mighty tool would bestow upon her. And even then he would use her, fucking her into a climax while she was unconscious.

At that moment it wasn’t even a question anymore.

“Y-YES! W-We will marry youuuuuuuuuuuuuuu~” the mare screamed out loudly, her pussy contracting as she was sent in a climax. Instantly a large rush of her juices splattered on his balls, taking him by surprise for a moment, before he grinned.

“A squirter, huh? I guess I will accept your proposal then. Though you won’t get any rest until I’m done with you!”

The last sentence was a blessing as much as it was a threat and Luna could only squeal in happiness as he continued to fuck her, not even noticing anything around her at that moment.

Not even her own sister.

Said white alicorn mare looked at the spectacle slack jawed, still in her position from before.

Thorax laughed a bit strained at this situation, not sure if the Sun Princess was approving of what had just transpired. Especially with his sensitive flesh so close to her possible attack range should she have an issue with the way this engagement was settled, “Well...I guess this reward is also good for getting closer together and developing a relationship build upon the more...passionate side of love,” the King said, trying to calm the situation. He then saw Celestia nod stiffly.

“I...um...yes...I...I guess it can…” she answered seemingly quite surprised by the outcome. At the same time though, her pussy had never stopped dripping upon his balls, making Thorax grunt as his cock throbbed in a clear need. The slight swaying of his impressive shaft drew the Princess back to what she was about to do before, her eyes practically transfixed on the pole in front of her.

There was some worry she felt at this now. Pulling actually through with this. Though her mind quickly came up with many arguments against that very notion of skipping.

‘Luna would never let me live that down...once she is coherent again that is. And the agreement is already done. I said yes. Luna said yes. This is a contract. And if I know one thing, pulling out here would do more harm than good. Besides...Luna seems to be enjoying herself and I know Thorax won’t be acting up like Pharynx did, letting me control the situation,’ she argued in her thoughts, albeit the last part, while giving her some reassurance also made her feel yet again a bit disappointed. But she squashed that feeling as soon as it emerged and instead, focused her gaze back on the King’s large rod.

“I apologize for...keeping you waiting,” the mare told Thorax softly.

“It is quite alright,” he replied as Celestia suddenly moved forward, adjusting her position.

Her pussy lips hereby were wedged against the side of his cock as she went from bottom to its top, bending it slightly towards Thorax as she lifted herself up more and more to reach the tip.

This hot contact made Celestia’s pussy drool in anticipation, leaving a wet trail of her juices on the underside of Thorax cock until she reached the head. The mare felt the flat wide girth of it now nestling on her inviting slit.

She bit her lip, muffling her moaning as she slightly pressed downwards. It pressed into her opening, but seemed to be a bit wide for her, so she increased the pressure as she used her magic to hold it steady at the base.

Celestia herself felt a bit irritated by this, grumbling under her breath.

“Can’t you just fit you-”

And then the head popped in. Celestia’s body bend forward, her head getting closer to Thorax as she let out a slight cry from the sensation of having the tip enter her until then virgin folds.

“Are you alright?” Thorax asked, making Pharynx next to them scoff yet again, though they disregarded it.

“Y-Yes! I just felt a bit surprised by the sudden entry,” Celestia admitted a bit embarrassed, avoiding her eyes as Thorax continued to smile at her.

“It is alright. Just start when you are ready.”

The Sun Princess nodded, breathing in and out before slowly lowering herself, feeling the cock push her vaginal walls open and stretching them out in a strange albeit interesting way, new unknown pleasure shooting from the nerves up into her mind.

‘Oooooh! Now I understand what Luna meant!’ she thought a bit giddy, a grin forming on her muzzle as she lowered herself fully on his cock before being stopped at the entrance of her womb, surprising the mare. ‘And he is not even going fully inside!’ she marvelled as she saw a bit of his cock still staying outside.

It certainly was different to Luna, seeing as Pharynx did get every inch of his cock into her. Something that made Celestia feel a bit cocky.

‘Seems like I’m the one winning this over you sister,’ she thought before shaking her head, trying to lose that perverted sentiment of bragging to her sister about Thorax’s length, ‘Just what are you thinking Celestia? You silly mare.’

Instead of giving this topic any more thought, she simply attributed it to her heat and started to lift her well-formed flank up again.

The way she felt the shaft rubbing along her walls made her moan out, before she reached the tip and sunk back down, enveloping the cock again in her heat.

The pleasure was all encompassing, the Princess enjoying this ride as she pulled the cock out and pushed it back in, in an ever increasing rhythm.

“Ah. Aah. Ahhh. Ah. Ahh,” she moaned in curt cute bursts each time she lowered her hips to the deepest part she could manage.

Thorax meanwhile had reached his hooves out, laying it on the lower part of her flanks and caressing the soft fur as he just continued to watch the mare riding his lap.

Celestia’s horn lit up at that, positioning his hooves higher, making sure to signal him that it was not only fine with her but also greatly encouraged to fondle her derriere.

The King understood, starting slowly as he squeezed her plush buttcheeks, making Celestia moan in her riding while Thorax continued, his hooves following her rump up and down in their movement as well.

He was rather surprised how well the pristine mare had adjusted after the loss of her virginity. Her eagerness and constant bounces on his shaft were rather pleasing, and from how he felt her moist cavern clamp on him, he was sure that feeling was mutual.

His groin by that point was rather sticky, showing that the Princess had emitted much of her own arousal as she carried on. Her body was slightly sweaty from the exertion and her expression was heated and needy.

He almost forgot about his brother and the Night Princess by that point. At least if it wasn’t for the latter one squealing and screaming out constantly.

“M-MOOOOOORE! HARDEEEEEER! WE BEEEEG OF YOUUUU!” she cried out as he saw Pharynx’s hips becoming a blur of speed, constantly pounding into the darker alicorn’s tight looking snatch. The mare wailed helplessly, another climax rocking her entire body and making Pharynx grunt rather noticeably.

“You better be ready slut! I’m about to cum! So, you little whore, best tell me now if you want me to impregnate you or to pull out, though I imagine the answer will be obvious,” Pharynx mocked while still honoring the agreement. Still, it was little more than a formality. Some drooling cunt like Luna would hardly protest at this point.

“I-INSIDE! D-DO IT DEEPLY INSIDE! B-BREED ME HUSBAND! MAKE US CARRY THINE FOAL!” the mare screamed just a moment before Pharynx smacked into her one last time.

Instantly his cock pressed against the entrance of her womb, shooting out thick ropes of slimy seed against it and pumping his load in her canal and most sacred place at the same time. Luna came yet again, gushing a flood of juices at this ultimate form of tainting her purity, making her nothing more than a cum-leaking whore.

She elated in the dominance, a loud high-pitched whinny escaping her as her body locked up in this powerful sensation, before she collapsed in her afterglow.

Pharynx took a moment more to dump the last of his seed into his future wife, before sighing out and pulling his dick out of her. Her cunt twitched slightly, a river of cum slowly dripping from it.

“Ahhh. That was quite good. Guess alicorns are a fine breed after all,” Pharynx noted with a grin at the unresponsive blue furball of pleasure.

He then looked over to Thorax and Celestia who were there right next to them, his eyes travelling along her well filled out form before he noticed something.

“Still going? I know I started a bit earlier than you, but not by much. Honestly, I expected you to have blown your load ages ago brother.”

“I’m not a premature ejaculator!” Thorax defended himself, but his brother didn’t listen as he snorted.

“Yeah, sure. What a snooze fest.”

Even during the pleasure and nice slippery bounces of Celestia, Thorax couldn’t quite shut his loudmouth of his brother out. It nagged at him, making him slightly glare at the changeling in question.

“She is enjoying herself, and I’m enjoying myself! There is nothing wrong or snooze like with that!”

“Please brother. Females of any race want a STRONG male on their side. A dominant, well-trained male that isn’t afraid to take charge and take what is his! And that little sun slut is no exception to this!”

Thorax growled, his grip on the mares flanks tightening and making Celestia shudder as she glanced at the two of them, listening attentively to this argument. She of course never stopped her movements, and from how Thorax was slightly pulling on her ass neither did he want to stop despite the situation.

Pharynx instantly noticed her staring, his dominant eyes falling on her, making her feel a bit of unease and lust.

“Reply honestly, would you rather ride his cock, or have me pressing you against a wall and taking your pussy hard from behind?”

“I-I, um,” Celestia stammered seemingly thrown off by that question as her pussy clenched in elation from the mental image. She barely managed to bite her lip and suppress a moan. Luckily Thorax quickly jumped in.

“Pharynx!” he warned in a reprimanding tone, making his brother scoff.

“What? You wanting to tell me Celestia looks more satisfied than my slut here drooling deliriously on the table?” he continued, pointing to Luna who was watching the ceiling with a dumb smile on her face.

“I’m not even done yet!”

“Done? You are done! You are way too soft brother! When do you finally learn to let loose and grow a fucking spine!”

While aggression welled inside the King as his glare got more and more venomous, Pharynx pressed on unhindered.

“You know, if you are being such a cuck, maybe I should go over there and finish the job myself with your bride! Maybe that gets her rocks off!”

At that moment something in Thorax mind clicked. The mere thought of his brother doing this fueled a certain rage into his being. A rage that the Changeling King quickly converted into sheer dominance.

His horn flared up, grabbing his brother and slamming him over the table and into the ground with his back.

Pharynx was surprised by this, not managing to even put up a struggle, even after he recovered as his brother still held him tightly in his magical grip.

“Fuck you Pharynx! You want to see dominance? You want me to grow a spine? Fine then! But don’t complain to me afterwards!”

As Thorax finished that sentence, he pulled Celestia off by her mane, making her cry out in surprise from the sudden pulling sensation along her scalp. The magical grip, made her backstep of the table and forced her to turn around where Pharynx lay on the ground. She then was pulled with her face towards the wall before she was pulled up, having her upper body press against the wall, her pussy now perfectly aligned that it hovered far over Pharynx’s head. The surprising dominance on Thorax’s part made the older mare leak her arousal, the sticky juices dripping down on the other changelings head.

A moment later a loud obscene moan echoed from Celestia’s throat as Thorax fat changeling cock was shoved back in as he mounted her.

“Is that dominant enough for you brother?!” he hissed as he started to brutally fuck the mare, his hips a fast blur as he smacked hard into her backside, her ass jiggling on contact.

The mare herself could only cry out and squeal as she felt her vaginal tunnel violated in such a manner. The cock practically hammered on her womb as well with a force that made the mare wonder if she could really take this.

She couldn’t.

A climax followed along a loud whinny as a torrent of marecum splattered from her cunt and down at Pharynx’s face, making the changeling sputter. Though it wasn’t nearly as much as Luna’s in direct comparison, still it was enough to make his head sticky in large parts.

But Thorax still was far from over as he simply carried on, stretching Celestia’s marehood deep and wide, his head colliding with the entrance of her womb repeatedly, that is until the mare could feel her walls yielding and all of a sudden the large changeling prick broke through the entrance.

Celestia screamed out as the hard rod suddenly rested in her womb and only then his tip scraped against the end of it did his balls finally make contact with her rear, slapping on it wetly.

‘H-He is inside! F-Fully inside my sacred and untouched womb!’ the mare could barely manage to finish that thought as Thorax didn’t seem to even care about the way he was tainting her as he just pulled back before pushing back in. He never missed a single thrust as his cock pressed into her womb again each time.

Celestia herself got louder after this, her pleased moans probably could be easily heard around the castle at that point. Especially as she came again, and another deluge of her juices gushed from her spread slit and down on Pharynx.

“Like that you slut?” Thorax growled out, “By how much you are wetting my dick I will take that as a yes. Though you bitch can forget about our agreement beforehoof. This is not enough of a reward anymore. So here is what will happen, you will not only carry my foal, but you will also marry me, though that doesn’t mean we are on equal footing. Behind closed doors you will be my slut and obediently slurp on my cock. Is that clear?” he asked in a slightly threatening tone that made Celestia shiver in clear bliss as she nodded hastily.

“Y-Yes!”

“Good. I will breed you now. You best be grateful for the honor of having my seed poured into your whorish womb!”

“Y-Yeeeeeeeesss!” the Princess of the Sun cried out, her pleasure mounting. She could feel that he meant it. Every word. He wasn’t the same changeling King as before, but something much more dominant. So dominant the white mare delighted in the loss of control as she anticipated his burning hot changeling spunk. And from the way his cock was throbbing, she wouldn’t have to wait for long.

As if on cue Thorax hilted with a growl, his humongous balls pumping their load into the mare’s womb. It was flooded full with his sperm instantly, her belly bulging as her womb expanded. She could practically feel the sea of sperm drowning her helpless egg in it as she was impregnated in a mere second. It was so delightfully depraved and hot, the mare couldn’t help but cum again.

Thorax meanwhile huffed before with one strong tug pulled his cock out completely. This had the side effect that a ton of sperm and marecum came shooting out from Celestia’s now loose hole and it all splattered down on Pharynx’s head.

The changeling could barely react as he felt his entire head and much of his body being drowned in this impressive load.

“Argh! Ptui! You little fucker!” Pharynx cursed at his brother.

“It is just a bit of cum. Grow a backbone,” Thorax jeered as he pulled his brother out from under the mare just as she slid down the wall, collapsing on the ground in a powerful afterglow, her wings twitching.

He then levitated him up before setting him down next to Luna on his back. The mare being coherent at that point and having gazed the spectacle with interested eyes. She was captivated enough that she didn’t speak, simply wanting to see how this argument between these two brothers would end.

Pharynx meanwhile glared up at the bigger changeling fiercely. Normally it would have been enough to make Thorax cower, but this time he didn’t seem to be affected. Instead he grinned as his eyes danced between him and Luna.

“Hey Pharynx. Remember that one time I told you about my crush on Apocrita and then found you fucking her one hour afterwards?”

“So, what about it? I simply showed you how it is do- Hey! What do you think you are doing!” he growled as Thorax set the tip of his large member on Luna’s wet, cum-leaking hole.

The mare was at attention, looking up surprised as her pussy quivered from the attention of another thick piece of changeling meat.

“Just revising the plan dear brother. Just revising the plan,” he answered casually before pressing into the cunt of the Night Princess, popping his head in and making her let out an elongated moan while suddenly a large gush of her juices and cum spurted out. It ran over his cock and balls in a wet splatter. Much more so than Celestia. Luna seemed sensitive enough to cum just from insertion. And she came in generous spurts.

Thorax could with certainty conclude that Luna was most definitely one messy cunt. Celestia, even in her most delirious state seemed more dignified than her, the writhing mare beneath him. Though the fact that she squirted so much more than Celestia was quite refreshing.

One could say the Sun Princess’ constant dripping didn’t hold a candle against Luna’s messy wetness. She was a monsoon of her dripping hot and sticky cum.

But it wasn’t the only difference.

Interestingly enough it turned out that Luna’s canal was about the same length as Celestia’s, meaning that despite her smaller size Pharynx wasn’t able to fuck directly into her womb as his cock ended right at its entrance.

Thorax of course had no such reservations, his cock hitting the closed entrance of her womb with ease even before his cock was fully in. Still he didn’t want to break it open from the start, he wanted to enjoy it. To enjoy seeing Luna realize that his cock was so much superior to his brother’s. So he pulled back before pushing in and making his tip hit the closed up entrance to her untouched sanctuary again.

“S-Sooo biiiiiiiiiiiiiiiig!” she moaned out shamelessly as Thorax chuckled down at her, ignoring the seething look of his brother.

“Who would have thought that simple pheromones would turn you little bitch into a huge whore for changeling cock?”

“P-Pheromones?” Luna asked, her senses barely able to pick it up during his thrusts.

“Yesssss,” hissed the King out aggressively, “Changeling pheromones to increase your lust and send you in a strong unbearable heat. Otherwise we hardly could bring you in the mood. It was Pharynx’s idea actually, saying we needed to do everything we could to save our subjects. Though in the end it is not like you whores are complaining about it, aren’t you?”

“Mmmmmhmphhh!” the mare exclaimed in an affirmative, her back arching and her pussy tensing as it sprayed her juices wildly, before she slumped back down.

“Sensitive. I certainly can appreciate that.”

He increased the cycle of his movement, making sure to fuck her hard and his brothers cum right out of her. Luna herself could only moan and cry out for more as she was taken by another changeling than her supposed future husband.

Once he felt she had gotten used to it, he upped the pressure he gave on her womb, spearing it open on his next thrust.

A squeal followed as well as another climax of the moon slut, more juices spraying from her needy hole as Thorax continued to smack her plot.

This went on for another ten minutes in which the King was stretching out her until then untouched sanctuary. He made sure to rub his cock all over her insides, giving the mare great pleasure and causing five more highs for the by then completely out-of-it and needy Princess.

Only then, when he felt she was his, did he allow himself to cum.

His searing hot seed shot directly into the mare’s womb, filling it up, just like it did with her sister. Her whole body jittered as she let loose one last loud cry before going limp, panting in her afterglow.

Changeling Sister on the Negotiation Table

Author's Note

This is the Eventual Consensual Rape with Genderbending part.

Changeling Sister on the Negotiation Table

After that he pulled out, satisfied with his work while his brother still glared at him hatefully.

“Satisfied now brother?” Pharynx hissed out as Thorax shook his head.

“That is what I should ask you. You were the one that demanded I should be more dominant. Besides that, I’m not done yet. You are after all still left. Aren’t you?”

“Still left? What nonsense are you talking about brother?” the changeling asked now confused.

“The mission was to establish a marriage. Though I am not satisfied yet. Even less with how you have been treating me during this whole affair so...I’m going to use one of the older changeling techniques and will be asserting my control over you.”

With that being said Thorax stepped with his front legs on the table lowering his glowing horn to the struggling changeling’s head. Once contact was made Pharynx felt a certain pressure building in his mind as certain parts seemed to get rewired. Parts about a section of his identity. He tried to push back, but his influence easily caved under his brother’s dominance.

Barely a minute later Thorax pulled back, stepping off the table as the darker changeling grunted out, his body shaking.

With that it started. Pharynx had only enough time to yelp before his body suddenly changed. First he felt his antlers becoming more slender and curvier, followed by his entire face shifting, his hard edges softening giving him a feminine look about it. It continued on from his neck downwards, his cries suddenly turning more high-pitched in their distress. His trained form meanwhile became lighter, edges rounding and giving him a flatter stomach and a more feminine curve. Then came his butt. The once so flat and firm carapace rounding out and puffing up, giving him a generous juicy looking backside. Not quite like Celestia but certainly more than that of normal mares. Lastly his cock and balls slowly vanished completely, and instead a set of full pussy lips formed. In the end of the transformation Pharynx’s new body was that of a curvy soldier that would cause many wet dreams.

Overall Thorax was very happy with the changes and wished he would have had such a sexy sister beforehoof.

“W-What did you do?!” squeaked the now female changeling.

“What I should have done to you for a while, sister. Though I never thought I would have to use one of the old Queen’s tricks to assert my will and with that a gender change on you, it is quite the useful tool for unruly beings like you.”

“I-I’m your family! I-I protected you!”

“And that is the reason why I am so lenient. I will keep you at my side, just like Luna and Celestia. A slutty changeling for my personal herd.”

Just as Thorax finished that sentence his eyes went over Pharynx’s newly formed virgin marehood. He couldn’t help but lick his lips, making his sister cross her legs in a new sense of unease.

“Seems like you turn out to be the spoilsport now sister,” he reprimanded her before his horn lit up, the glow encompassing the female changeling yet again. He then lifted her up before turning her around and lowering her belly to Luna’s.

“Y-You are not serious, are you?” Pharynx asked as she looked back though her brother didn’t answer. Instead he grabbed her flank, kneading the plush ass with his hooves and whistling in approval and showing how serious he really was.

“It is plush but firm, showing off quite well your muscles still. I certainly can appreciate that.”

“D-Don’t you dare!”

“Or what? Are you going to embarrass me with old stories about how you made me hit myself?”

Pharynx grimaced, keeping quiet and not sure how to react to her brother’s statement.

“I…” she finally tried, but still couldn’t come up with an answer as she thought on it and the many interactions they had. Her head was turning back forwards as she continued to mull it over.

It was then that she noticed that Thorax was right in a way. She was almost always a rather big jerk towards him, seeing all he did in a more negative light, despite him actually managing to become the leader of the hive.

A wave of regret washed over her the more her mind dwelled on it. She felt like she had to right it somehow.

“Thorax I-AHHHHHHHHHHHHHH~” she started but was interrupted by her own surprised cry as suddenly without warning her brother’s cockhead was forced into her tight pussy. And it was tight. Even more so than Celestia and Luna, making the King grunt as he forced this new hot cavern open. His cock at least was lubricated more than enough for this task.

“Tight one. Aren’t you sister?”

“T-Thorax! S-Stop this nonsense this instant!” she warned, but Thorax scoffed, not unlike her own scoffs, making the changeling mare fume while adopting a cute pout.

“No can do sister. Y-You deserve this, so I’m not going to stop until I have impregnated you as well!” he asserted as he started to move, his shaft moving inside and out of her, starting to rock the smaller changeling’s body. Much to her own confusion this actually affected her. She felt the cock scraping over new nerves she never experienced before. Something that felt good in its own strange way she tried to mentally block.

It went about as well as one expected as her body reacted, her pussy producing its natural juices as it was stimulated by the majestic member of her King and brother. She could do little more than bite her lip as she cutely grunted, trying to hold any pleased noises in.

Though it was a losing battle. Barely a minute in had the mare’s slit winking erratically.

Feeling a mischievous side in Thorax pop up he grabbed her button in his magic squeezing it. The resulting spike of pleasure threw his sister off, making her moan out loudly, clear for all to hear.

It was a sound that made Pharynx gulp as her eyes gazed back at her brother who spotted a predatory grin.

“Is that a moan you little slut? Are you enjoying your new body a bit too much?” Thorax mocked making her blush.

“I-It’s nothing like that idiot!” she quickly uttered, turning her head away in embarrassment.

“Really now? Let’s hear these cute sluttish bits of nothing a bit more!”

After saying that he increased his pace, his cockhead diving in deeper and deeper into his sister’s folds. Thorax certainly was surprised to find that he could go in really deep without finding the entrance of her womb. Another interesting feature to his sister. Something he planned to explore further in the future. For now he was interested in following up with his intentions, which is why he made sure to go as deep as he could into that hot tight hole, making his hips smack into Pharynx as she tried to hold her pleased sounds back.

It felt rather rewarding to him as her grunts quickly turned more into cries of pleasure. Her pussy slowly became more accommodating too, getting adjusted to his form and welcoming his thick rod openly as it seemed to pull him right in.

His sister certainly was enjoying herself, even if she refused to admit it.

And then she came.

Her juices splashed against his cock and balls, her walls constricting as he pushed through the resistance carrying on with his speed and making sure to fuck her right through her climax as she cried out loudly.

Once she was done she was quiet. Or tried to be quiet as if hoping she could hide herself is she just kept her mouth shut.

“Seems like my sister is a whore who gets off on having her pussy fucked hard by her brother,” Thorax teased.

“I-I’m not,” she denied quietly and Thorax simply chuckled.

“Yes, you are. And you will be cumming on my cock everyday from now on as well. I will fuck you right as you wake up, even before the slut sisters. And you will go to bed sucking on it like a good little bitch at night,” he purred in a husky voice that sent tingles down the newly transformed mares spine.

“B-But we are siblings! You can’t do this!” she tried to deflect even as her pussy clenched on his prick.

“So? Honestly, this makes it only better for me. To fuck the virgin pussy of my own sexy sister and make her fall in love with my cock. It is also the dominance you always demanded from me. Would I have done with my first crush, what I right now do to you, you wouldn’t have complained.”

“T-That might be but this is different!”

“How? If I was female, I doubt you would have hesitated to use me in such a manner. Be honest. A weak little female changeling sister is something you would have preyed on as payment for your protection.”

‘I-I would…” Pharynx admitted in her thoughts as images of a weak female changeling sister invaded her mind. It wouldn’t have stayed with words and making her hit herself. She would have claimed her properly.

“Besides, you are enjoying yourself, so you might as well get used to it, seeing as you will join my royal herd anyway.”

“W-Wait, herd?” she asked, that one word bringing her back from her debaucherous thoughts of an alternate sibling.

“Of course. Or do you believe I would simply fuck you just as hard as the royal whores if I wasn’t planning on bringing you into this as well. You were planned in the royal wedding too. It just changed in the regard that you and Luna will belong to me now.”

“I-I will never agree to become your slut wife!”

The King grinned at that line, leaning closer to her ears, “Oh, I was hoping you bitch would say that.”

After that Thorax positioned his front legs on the changeling’s shoulders, gripping them tightly before he continued to ram that attractive piece of ass in earnest.

Pharynx struggled as she tried to hold on, but with how Thorax continued to stimulate her nerves and how he actually had her sensitive love nub in his magical grip, playing with it, she could hardly hold on, getting sent into another strong climax that left her eyes unfocused and her mouth panting by the end of it.

He didn’t slow down. He wasn’t going to go easy on her. And his stamina certainly was rather impressive as she couldn’t feel any indication that he was close to cumming.

“You are so preeeetty!” Luna meanwhile giggled drunkenly before slobbering over Pharynx’s lips in a messy kiss. The Princess, despite her thorough fucking still seemed horny enough to engage in some fun with the changeling mare.

The pleasure drunk Pharynx could hardly fend the Night Princess off, surrendering to the sloppy make-out session as she felt the mare’s tongue shoved right into her maw.

She could only moan as she continued to get fucked, Thorax seemingly never tiring.

The continuous slaps echoed against her wet plot, strings of arousal connecting her with the King, before ripping apart as he pulled out and then forming anew after his hips collided with her juicy plot.

Luna simply licked away at the cum on her face while Pharynx moaned, looking straight ahead, only to be blindsided by another kiss. The perfectly white lips of the Sun Princess appearing in front of her and capturing her as she cried out into her mouth.

The kiss was broken as Celestia intently stared at her sister and the two changeling siblings, seemingly taking the perversion of incest in. As if drawn in by this concept, or maybe just driven by her heat she then also captured her sister’s lips in a kiss. The darker mare surprised at first, but didn’t protest.

Thorax grinned, loving the show as he was seesawing into his sister’s cunt. He groaned out in bliss as his balls slapped against her. He was feeling that said sweaty orbs were about ready to empty his payload deep into his sister.

“I’m cumming! Best be ready sister, because I’m going to breed you like the little slut you are!” he announced, making her sister’s eyes widen in horror.

“N-Noooo! N-Not inside!” she cried out, weakly struggling, before a moment later Thorax did just that. His movements ceased as his cock was nestled deep into her, before his mighty rod fired thick slimy ropes of seed deep into her.

Pharynx groaned, her pussy quavering in another pleasure-filled high as she felt a distinct hotness in her belly.

For a minute nothing happened after that. Nothing but Thorax’s cock spurting his loads into the the smaller changeling mare. Once it ceased and nothing else happened she piqued back up.

“I-Is it over?” Pharynx wondered with a tone split between relief and disappointment.

A sinister chuckle emanated from behind her, but before she could turn her head Thorax started to move again, making the surprised changeling mare yelp as her sensitive walls were once again violated as her brother’s cock continued to scrape over them.

“It is not,” he simply stated as he proceeded.

This continued on for four hours. First Pharynx still tried to hold back, her moans stifled. Then she screamed out as her sensitivity increased with each load, her mind being overloaded with sensations. After that she felt herself slowly moving her hips back into him as Thorax chipped away at her last bit of resistance.

Eventually she caved, and after the fours hours of nothing but pleasure she ended up bouncing on her brother’s cock out of her own free will as he laid on his back on the table, a Princess in each of his forelegs snuggling into him as he enjoyed his sister’s servitude.

She could do little more than moan as she felt the cock rubbing along her insides, a needy smile on her lips as Thorax grinned.

His herd was complete.

8 Months Later

Pharynx trotted down the corridor of Canterlot castle.

Her large pregnant belly swayed with each step she took as she went to the large private study most of her herd would be at.

She hummed in thought. A lot of things had happened since that fateful day.

Back then she had awoken something in Thorax. Another side of him much more fierce than Pharynx ever imagined.

And a side Pharynx ironically would have to control. At least after she got back to her senses.

She couldn’t count the times how often she had to hold her brother back when a female showed even an inkling of disrespect. She wouldn’t have to be a bitch. Just a simple misunderstanding was enough for Thorax to want to assert his dominance over her. It was only with lots and lots of effort on her part, which involved offering her face up to his cock in some bouts of violent facefuckings, that Thorax didn’t lay half the castle.

This dominance would have been admirable if Thorax didn’t cause her more work in trying to cover for him. Or the many times she had to ‘convince’ him to let it go.

But then again, she actually had gotten used to her female body and the bribes she had to administer to calm her brother, so that wasn’t necessarily that bad. Especially seeing as how she secretly was enjoying even those times he uses her face. Though seeing how she always rubs her hoof into her marehood needily when that happens, it probably wasn’t that big of a secret to her herd.

All in all things went rather smooth interestingly enough. Their forming of a herd in a marriage might have had some enemies, but nothing one couldn’t solve in the end.

Finally she came to the doors. Soundproof. It was rather awkward to explain the loud obscene noises from their first time, so it was safer that way. The Princesses needed to act regal in public, and squealing out and begging for cock like whores daily certainly weren’t noises the public should hear.

She then stepped into the room, making sure to close the door quickly to see Thorax dismounting from Luna, his wet messy cock no doubt pulling out of her cunt as the mare turned her head to him, an argument clearly going on.

“B-But it is Nightmare Night! I-I do have to go back out and hold a speech!”

“Do I look like I care?” he teased her as one hoof fondled her rear, “You will simply do it with my seed dripping out of your impregnated hole, leaving a nice trail of cum behind wherever you go. Is that clear?”

Princess Luna shivered delightfully as she shrunk back under his intense gaze.

“C-Crystal,” she affirmed, making Pharynx roll her eyes. Luna certainly was a glutton for punishment. Often enough she provoked and challenged their King just so he could give her some degrading task to fulfill in public. The changeling mare started to think her fellow wife has an exhibitionism kink.

“Ah, you are back sister?” Thorax asked her as he turned to the mare.

“I am reporting back for duty,” she nodded bowing her head and closing her eyes in a clear sign of submission.

Seconds later she could feel the cum-stained tip of his cock poking her muzzle as he had stepped over her.

Her eyes opened and she obediently opened her mouth suckling on the salty tasting head.

“Good. I was in need of your services anyway,” the King said, but before the mare could go further he used his magic to prop her up in a sitting position with her back against the desk. He then stepped over to her with his forelegs standing on the table, his shaft again pushing against her lips.

She opened her mouth without hesistation, just as he started to buck his hips, sinking his cock deep into her throat. Soon wet noises emerged from their position, the mare’s face smeared with spit and pre as she was facefucked by her brother.

A hoof wandered past her pregnant belly and to her slit as she rubbed furiously on it, moaning on the cock as her tight gullet massaged it rhythmically like she had done so many times before.

In her position she didn’t even notice Luna pouting as she left the room.

Pharynx was a wet mess by that point, simply going with the flow and enjoying herself as she was used like an onahole for her brother’s pleasure.

This was her duty. To her King, Husband, and Brother.

Thorax was her responsibility, so she would continue to support and serve him like a responsible older sister. She would help him, even as her brother continued to rut her senseless and would breed her with many of his hatchlings.

She delighted in the tasty pre as she worked to make him cum. Now and forever.
