"We need to talk." Twilight Sparkle began in a serious tone as she faced her big brother. "Shining I… I think you’re making a big-"

"Ahem!"

The abrupt sound of somepony clearing their throat interrupted the mare and got both siblings' attention. They both turned to see none other than Princess Mi Amore Cadenza, AKA Princess Cadence making her way down the stairs.

"I do hope I'm not interrupting anything, honey." She said as she approached the two Unicorns, her voice practically dripping with venom as she gave Twilight a very annoyed glare.

'She sure has a way of sneaking up on ponies…' Twilight thought to herself as she narrowed her eyes, almost ready to fire back with a retort of her own…

…only for Shining Armor to chime in. "Oh! N-Not at all, sweetie." He replied with an uneasy smile. "My little sis and I were just going over some last-minute preparations for tomorrow's rehearsal."

The lavender Unicorn couldn't help but spare her brother a sympathetic glance, something about that smile felt… forced. 

Cadence on the other hand merely scoffed, turning her attention to Shining. "Could I speak to you for a moment, dear?" She asked, right before turning away and storming towards the adjacent room, making it very clear that it was more of a demand than an actual request.

"Better see what she wants…" Shining said, letting out an exasperated sigh as he trotted after his fiance.

Twilight barely held in an aggravated groan as the door closed behind him. 'What is that mare's problem!? I've heard of bridezillas, but she's just being a total cunt!' She mentally fumed as she paced around… only for the sound of muffled shouting from the other room to catch her attention. Arching a brow, Twilight snuck closer to the door and listened in on the two.

"…I thought I made it perfectly clear that I didn't want you to wear that!" She heard the Alicorn snap, her tone even more demanding than before.

"But it was a gift from my Uncle, I just felt I should wear it for the occasion." Shining replied, sounding rather offended. Not that Twilight blamed him, Uncle Dusk Shine was such a nice stallion-

"Are you disagreeing with me?” Cadence asked, her voice dripping with disappointment as her eyes flashed an eerie green.

"Y-Yeah…" He replied, his body suddenly seizing up as he rubbed his head in pain. "I... I guess I am...?" The Unicorn groaned, his voice wavering right before he crumpled to the floor.

"Oh, dear! Are you getting another one of your headaches?" The Princess asked in a condescending tone as she approached the Unicorn, her horn glowing menacingly. "Let's fix that..."

Then, to Twilight's horror, Cadence struck her brother with a beam of lime-green magic right between the eyes! The lavender Unicorn recoiled in terror as her brother's eyes rolled back in his head, his body convulsing as he writhed in pain... before suddenly going still.

“Feeling better?” Cadence smirked, her horn still glowing as the stallion slowly staggered to his hooves.

"Mmm-hmm..." Shining nodded in a dazed manner, moving like a puppet on strings. "I think so..." He murmured, his eyes still unfocused.

The lavender Unicorn watched in abject horror as she took several steps back, struggling to contain her rising panic. “She isn’t just unpleasant and rude… she’s downright evil!" She whispered to herself, her breathing suddenly becoming more rapid. At first, she was tempted to flee as quickly as possible, find the Princesses, her friends, get help…

… but that would leave her brother alone with this… monster! And she couldn't allow that, she wouldn't allow that!

Not wasting another second, Twilight slammed the door open with her magic and rushed towards the Alicorn with her horn charged. "STAY AWAY FROM MY BROTHER YOU WITCH!!" She screamed, unleashing a volley of magic blasts upon the Princess.

"What the-GAH!" Taken by surprise, Cadence swiftly spread her wing and took off towards the ceiling, narrowly avoiding the worst of the onslaught. Thinking fast the Alicorn summoned a shield around her body just as the Unicorn fired off another blast of magic. "You just can't keep your nose out of other pony's business, can't you?!" She snarled before dispelling her shield and letting loose a burst of magic, sending several bolts of green energy throughout the entire room.

The lavender Unicorn narrowed her eyes and teleported out of the way, reappearing right next to her brother and summoning a shield of her own around both of them. "Hmph! Nice try." She smirked as the bolts bounced harmlessly off her shield.

"I certainly thought so." Cadence smirked as she landed, her eyes glowing for a second as she tucked her wings back in.

Before Twilight could retort, pain surged through her body as she was struck from behind by a different blast of magic, her body was slammed into the wall and slumped to the floor shaking in agony. "W-Whuh... who...?" She groaned, desperately trying to fight off the pain, but as her blurry vision started to clear up, she found herself staring up at… her own brother. "Sh-Shining…? But why...!?"

"Because he's under my total control, of course!" The Alicorn smirked as she approached the injured Unicorn. "It took a few… repeated attempts to keep him in line, but the results speak for themselves, wouldn't you say?" She chuckled, running her hoof down along Shining's jaw and chin. "You've been quite the annoyance as of lately… but I have heard some good things about your talents when it comes to magic, and that could be useful to me."

An icy cold chill ran down Twilight's spine as she stared up into Alicorn’s eyes. "What… do you mean…?'" She asked, her voice trembling as the dark look on the Alicorn's face grew more intense.

"It's quite simple, I've decided that you are a necessary tool." Twilight's expression changed from confusion to horror as Cadence's cheerful voice was suddenly distorted by a sort of… buzzing undertone. "That being said, I do think we got off on the wrong hoof." The Alicorn continued as she levitated Twilight off the floor, bringing her closer until their lips were inches apart. "So let's kiss and make up, shall we~?" She cooed, moving in close enough for Twilight to see her own reflection in the pupils of her eyes… before kissing the Unicorn deeply and passionately, her snake-like tongue invading Twilight's throat as a beam of energy erupted from her horn and struck her right on the forehead.

"Hrrkk! Wha… what are… you-" Twilight grunted through the kiss, trying to pull away from the Alicorn, but soon found it hard to even form a sentence.

"Shhh~, don't talk…" Chrysalis signed as she broke the kiss, wrapping her hooves around Twilight's body and stroking her mane lovingly as her own eyes flashed a light shade of green. “Just let it happen…”

Eventually, Twilight couldn't even think straight, her eyes rolling back as she faded in and out of consciousness…

"Oh and Shining? Set up a few more soundproofing spells so we aren't disturbed."

"Yes… Queen Chrysalis…" Was all Twilight heard before darkness finally took her…

-----

"Ugh… uuhn, w-what… what happened…?" Twilight groaned as she came back to her senses, as her blurred vision cleared up she was able to make out a distinctly feminine shape.

"Hello, Twilight~"

The Unicorn blinked in disbelief as she found herself staring at none other than Princess Celestia herself. The Sun Princess had apparently discarded her Royal regalia and her body seemed to be a little more… curvaceous compared to what she recalled, her hips and legs seemed oddly alluring yet defined, her wings much more imposing while giving off an inviting and nurturing aura, her flank was much more… plump than she remembered, to the point where Twilight could imagine resting on them like pillows, and she was laying on her bed in a rather seductive pose with a 'come hither' look on her face.

"P-Princess…?" Twilight exclaimed, taking an unconscious step closer to her mentor. "Why are you-?"

"You've done so well, my student. I want to thank you for helping keep Equestria safe. But alas, I have nothing to offer you…" The Alicorn trailed off before turning over to lay on her back and spread her legs, her expression changing from comforting to predatory as she exposed her belly, chest, and marehood to the Unicorn. "Nothing… but myself, that is~"

"I-I… I…" Twilight could only blush heavily as she watched her mentor expose loins so shamelessly. The lavender Unicorn found herself unable to think clearly, let alone form a proper sentence as her eyes were glued to the Princess' pure, glistening, untouched marehood as feelings of pure lust and desire plagued her mind.

"Won't you join me?" The Alicorn cooed, her lips curling up into a coy, sultry smile, the feathers on her left wing curling inwards like fingers as she beckoned Twilight closer. "I assure you, you'll feel very comfortable~"

"Y-Yes… Princess…" Twilight replied, suddenly finding herself unable to resist trotting up to the bed the Sun Princess rested on, feeling as though she was drifting through a blissful fog. A small, more rational part of her mind felt that something was… off, but that feeling quickly vanished as she got on the bed. It felt so soft, her right hoof sinking into the mattress, almost like a cloud.

"Good girl~" Celestia giggled, the Unicorn's heart swelling with pride upon being praised as she accepted her mentor's invitation, gleefully embracing the Sun Goddess. "You've done so much for Equestria, and so much for me, you deserve nothing more than pure pleasure~"

'She… she's right…' Twilight thought, nodding blissfully as she laid down on top of her mentor, her chest was pressed against Celestia's as the Unicorn nuzzled her neck, a cute yawn escaping her lips as Celestia's legs and wings wrapped around her. 'I've helped her… so much… helped Equestria so much… I can just… rest…'

"That's it, my faithful student." The Unicorn heard her mentor whisper as she hugged her closer, enveloping Twilight in a near intimate embrace, the Alicorn's wings forming a cocoon of warmth and comfort that Twilight never wanted to leave. "It's alright, forget about everything else. Your friends, your family, the wedding… it doesn't matter anymore."

"Whuh… wedd… ing…?" Twilight mumbled, looking up at her mentor dreamily as her thoughts started to become clearer, with a small sense of nervousness rising from the depths of her mind. "Was… what was I… suh… supposed to-" For a moment Twilight struggled to complete her sentence, but Celestia simply bent her long neck down in a swan-like manner and planted a small kiss on the Unicorn's forehead.

"Oh, that's not important anymore, sweetie." Celestia whispered, her lips inches from Twilight's as her eyes gained an ominous green tint. "Right now, you just have to focus on me, and all of your love for me."

Twilight felt her worries dissipate almost immediately, her body shuddering as her mind relaxed more and more… but, something still felt off… like she had forgotten something very important, one single detail that was nagging at the back of her mind as she felt Celestia's hooves wrapping tightly around her. But she knew that it was important, that she had to remember… something.

"N-No… I… ngh…" Twilight groaned in pain as she tried to push herself off of her mentor, but her head hurt so much when she tried to remember. "…we need to… need to stuh-stop… stop her-huh?"

The lavender Unicorn wasn't given a chance to finish as the Sun Goddess suddenly rolled over, forcing Twilight onto her back and gazing into her confused, vulnerable eyes with a predatory smile.

Then, before Twilight could react, Celestia bent down and locked lips with Twilight, the mind of the lavender Unicorn was almost immediately assaulted by a surge of pure bliss, the very feeling of the Princess' soft lips against her own, sending pulses of ecstasy throughout the Unicorn's body.

'Ooooh yesss… no, w-w-wait… I… I-I need to…' Twilight moaned into the kiss as Celestia shifted her weight and pinned her down against the bed sheets, forcing her tongue into the Unicorn's mouth to deepen the kiss. 'I… I have to… have… to…' Twilight thought as she weakly struggled against the weight of the Alicorn's body… but soon found herself returning her mentor's kisses as her worries faded away once more. They didn't matter anymore, all that matters was that she was with Princess Celestia, right where she belonged.

"Mmm… you really liked that, didn't you?" Celestia purred in a soothing tone as she broke the kiss, opening her mouth as wide as possible before inhaling deeply. Twilight let out a small, tired gasp, her body seizing up as several wisps of pink energy erupted from her mouth and were sucked into Celestia's waiting mouth. "Ahhh, delicious. Doesn't serving your Queen feel so much better, Twilight?" The Sun Goddess asked, licking her lips in satisfaction.

Woozy yet still conscious, Twilight nodded obediently. "Yeeeessss…" Celestia was right, everything felt much better when she trusted and obeyed this… perfect creature without question.

"Good girl~ Now there's only one last step to take before you're truly ready." Celestia said as she brought her head down towards Twilight's neck… and sank her fangs into her, piercing the Unicorn's skin. The Princess proceeded to pump some sort of fluid into her, causing Twilight to hiss in pain as a sudden burning sensation spread through her veins, the weight of the Princess pinning her being the only thing that kept Twilight thrashing about. 

However, after a few minutes, the burning sensation eventually subsided and Celestia let go, gazing down at the panting Unicorn with a triumphant smile. "Sorry about that, my faithful student. But I needed to prepare your body for what comes next."

Twilight, having been rendered almost completely delirious due to the fluids within her body, could only gaze up at her mentor in confusion. "Wuh-What… w-what did you do… P-Princess…?"

Celestia silenced any and all worries within Twilight's mind with a gentle smile as she caressed her cheek. "Oh, nothing you need to worry about… for a few minutes anyway." She began as she pulled herself off of the Unicorn. "After all, you must properly service your Queen before I give you your true reward~"

As she slowly staggered to her hooves, Twilight's face lit up upon registering Celestia's words. Not only was the kiss just a prelude to whatever wondrous reward her Mentor had prepared for her, but would be given the honor of servicing her before receiving it! "O-Of course my Queen! I am your faithful student after all!" The Unicorn replied eagerly as her eyes were enveloped by a green tint, never once questioning why her mentor had suddenly altered her title. And why would she? Celestia was above her in every conceivable way, it was only natural that she be given the love and respect she so rightfully deserved. Who was Twilight to question such things? "How may I service you? Just tell me and I'll do it! Anything at all!"

Smirking, Queen Chrysalis finally dispelled her disguise, knowing that her victim was too far under her spell to realize that her beloved mentor was actually the Queen of the Changelings.

And very soon, she wouldn't even care.

Spreading her legs as she sat down, Chrysalis exposed her marehood to Twilight once more, giving her a playful wink that made the Unicorn's heart skip a beat as she gestured for Twilight to come closer. The Unicorn nodded obediently as she approached her Queen, her eyes now glued to Chrysalis' crotch as she licked her lips.

However, Twilight's eyes slowly widened as the Alicorn's clit began to grow, a small aura of magic surrounding it as it grew bigger and longer, increasing in size and girth until it took the form of an average stallion's cock, minus the medial ring, and the flare at the tip was replaced by a strange bulbous shape. "Would you like to have a taste, Twilight~?"

Twilight took a moment to collect her thoughts as her cheeks turned red, realizing exactly how her Queen wanted to be "serviced". The Unicorn could feel her mouth watering from just looking at it, the thought of taking it all into her mouth and savoring the taste…

…it excited her.

"Y-yeah… I'd l-love to, m-my Queen."

"Well then… open your mouth." Chrysalis commanded with a soft, gentle voice, her ovipositor twitching in anticipation like a Stallion's cock.

The lavender Unicorn nodded, following the Queen's orders and leaning down towards the tip of Chrysalis' phallus and lightly grabbing the shaft with her right hoof before giving it a long, sensational lick. "Ooohhh yeah~" The Changeling Queen let out a soft moan as she felt the Unicorn's soft, smooth tongue licking her ovipositor, trailing up and down her length from the bases to the very tip.

Twilight's body shuddered as she savored the taste, it was the most exhilarating thing she’d ever tasted in her life! The "flavor" was indescribable, all she knew was that she couldn't stop licking even if she wanted to. 'S-So sweet… s-s-sooo good! Ooooh mother of Celestia, this tastes amazing!'

"Mmmph, ooohh, aaahhh! That's it~" The Changeling cooed, stroking Twilight's mane as her shaft continued to grow longer, to the point where it was practically towering over the Unicorn. "Such an obedient student~"

"MmmHmm…" Twilight sighed, the confirmation that she was doing a good job made her heart flutter, every moan from the Changeling encouraging the Unicorn to go even further as she happily dragged her tongue up to the tip of Chrysalis' shaft.

"Mmmhmhm, looks like somepony is having fun~" The Queen shuddered as she felt soft ripples of pleasure shoot through her cock. Then, as Twilight reached the tip, the bulbous part slowly opened up like the petals of a blooming flower, revealing its green inner flesh. "Don't stop now, you're doing sooo well~" Chrysalis cooed as thick, lime green fluid dripped from the puckered hole at the very center, she then gently pressed the tip of her ovipositor was against Twilight's mouth, the bulbous part flaring and closing as if to kiss her…

And Twilight was more than happy to oblige.

After taking a deep breath and opening her mouth as wide as possible, Twilight eagerly pulled the Changeling's ovipositor into her mouth, licking and suckling it like a foal.

Queen Chrysalis flinched as her sensitive ovipositor was engulfed by the Unicorn's soft, warm mouth. Intense surges of pleasure shot through her as Twilight gently licked at the sensitive inner flesh of her tip. "Oooohhh! Ooohh f-f-fuuuuck yes!!" Chrysalis gasped, instinctively thrusting her hips upwards as she placed both hooves on Twilight's head, after spreading her legs a bit more she then pushed the Unicorn's head down and forced more of her shaft deeper into Twilight's mouth.

The lavender Unicorn gasped as she felt her Queen plunging her shaft into her mouth and quickly attempted to open her mouth wider, eager to take more of Chrysalis' ovipositor down her throat. But just before it got too far, the Unicorn started bobbing her head up and down Chrysalis' shaft, her eyes half-lidded as she caressed her Queen's cock with her tongue.

Deciding that it was time to properly "prepare" the Unicorn for what came next, Chrysalis used her magic to spread the Unicorn's asscheeks, exposing her winking pussy. "Now it's my turn to taste you~" The Queen chuckled as her long, snake-like tongue slithered out of her mouth, dripping with the same fluids that leaked from her ovipositor as it slithered through the air and made their way between Twilight's legs, pressing up against her marehood.

"Aahhm!" Almost immediately upon contact, a moan escaped Twilight's lips as she licked around Chrysalis' shaft, her hips shaking as jolts of pleasure spread from her loins. The Queen's tongue lapped at her folds before parting her lips open, the Queen's tongue gently probing the entrance of the Unicorn's slit, getting slightly more forceful as it twisted and squirmed as far inside as it could manage. "Hhmmph, mph! Mph! Mmmm~!!" Twilight moaned in euphoric bliss around the shaft pounding her throat as she felt her Queen's tongue sliding in by an inch, exploring her insides and working its way deeper while carefully stretching open the Unicorn's marehood, searching out the curves of her insides.

Queen Chrysalis couldn't help but let out a small giggle as she watched her soon-to-be-broodmare twitching and stuttering from every inch of her tongue that slithered inside. It was a slow yet pleasurable process, the inner walls of the Unicorn's pussy instinctively clenching down tightly on her tongue. But the Changeling Queen was not deterred as the fluids secreted by her tongue allowed them both to slip deeper with little resistance.

'And now comes the really fun part…' She thought, pulling her tongues out of both holes, savoring the experience as she made sure to secrete as much fluid as possible, leaving Twilight's pussy almost flooded with them. Chrysalis then began pulling her shaft out of Twilight's mouth as well, gently stroking the Unicorn's mane as her shaft popped out of Twilight's mouth, a single strand of saliva being all that connected her lips to the tip. "Well now, now that we've gotten the foreplay over and done with. I believe it's about time you were told just what comes next, my faithful servant." She began as her tongue was yanked out of Twilight's marehood and retreated into her mouth, her smile now one of pure, restrained lust as she stared down at the Unicorn.

Still stuck in her euphoric bliss, Twilight let out a dizzy giggle as she gazed up at her Queen. "W-W-What… what's next… my Queen?" She asked, struggling to stand up straight as her head swayed from side to side.

"You see Twilight, as Queen of the Changelings I am capable of laying fertile eggs inside of another creature's womb, and over time my eggs shall feed off of the magic and love energy of the host." Chrysalis explained, caressing Twilight's cheek as she licked her lips, practically salivating at the amount of love her new servant felt for her. "And you… with your immensely potent magic, are the perfect host for my offspring." As she continued, Queen Chrysalis used magic to lightly tease the Unicorn's marehood, her own shaft twitching in anticipation with each passing second. "Doesn't that sound wonderful?"

Listening with rapt fascination, Twilight felt a strange mixture of pride, arousal, and kinship. Her Queen had chosen her to carry her offspring! She would have the honor of being impregnated with her Queen's children! Just the idea of it was enough to make Twilight's loins quiver, begging for attention.

"That sounds amazing, my Queen!" Twilight exclaimed with joy, crawling towards Chrysalis before turning around, spreading her legs and waving her flank at her Queen, her loins burning with a desperate need for release. "Please, put it in me! Fuck me! Fuck me right here, right now!! I want it so bad!"

Amused by the sight of the Unicorn's needy holes on full display, the Changeling Queen decided to tease the lavender Unicorn some more. "Oh, but I'm afraid my eggs would need a suitable amount of love from their host as well." She casually threaded towards twilight, giving her flank a firm slap and giggling as she watched it jiggle. "Do you really love me, Twilight Sparkle?"

The words had scarcely left Chrysalis' mouth by the time Twilight started shouting. "Of course I do my Queen! I love you, deeply, utterly, with every fiber of my being! You're the most important pony to me in my entire life!" She proclaimed, unable to go another second with her marehood burning with desire. "If you want to breed me then do it! Breed your faithful servant! Pump your eggs inside me!" The Unicorn pleaded frantically, it was almost as if something within her mind had broken, leaving her eager for more pleasure. "Knock me up! Make me pregnant! I wanna give birth to your young soooo bad!! Make me a mother!!"

'To think that the once proud student of Princess Celestia has been reduced to begging to be impregnated like a bitch in heat… truly my greatest work yet!' The Changeling Queen thought, biting her lip as she tried her best not to laugh at the pathetic display the Unicorn was putting on before her.

Satisfied with Twilight's response, Chrysalis decided it was done preparing/teasing her future broodmare and mounted the pleading Unicorn. "I warn you though, it'll take some time for your body to become properly adjusted… and I'm not feeling patient." She cooed as her ovipositor slithered towards the Unicorn's neglected, glistening pussy, which throbbed in anticipation.

The Unicorn shuddered as she felt the tip brush up against her pussy lips, prodding at her marehood, much to Twilight's utter delight. Chrysalis then leaned her body down on top of her, firmly holding the Unicorn in place as her shaft slowly parted Twilight's pussy lips, the fluids she'd secreted earlier making Twilight's entrance slick enough to allow her easy access… up to a certain point anyway.

The lavender Unicorn offered no resistance as she rested her head on one of the pillows, taking slow breaths as she arched her back and pushed her flank back, forcing a few more inches of her Queen's ovipositor into her aching pussy. 'Yes! More pleasure! Please!' Twilight thought, letting out a low moan of satisfaction mixed with slight frustration as she bit down on her hoof to alleviate some of the pain as her pussy was stretched. "Oh y-y-yesss… please, mor-HHRRKK!?"

It quickly became very clear that her Queen was done taking things slow as she forced her ovipositor as deep as she possibly could, the bliss of having her Queen inside her was quickly being eclipsed by the stinging sensation of her inner walls being stretched further with every inch of Chrysalis' shaft. While she hadn't been snapped out of the Queen's spell, Twilight couldn't ignore the pain as Chrylasi forced more of her cock inside the Unicorn.

"M-My Queen-ngh! It… it hurts-aaHHAAA!" She screamed as she felt something within her pussy tear just as the Changelng's ovipositor was shoved deeper and deeper, inch by agonizing inch, the pain becoming so intense to the point where Twilight contemplated begging her Queen to stop.

But that was all about to change.

Unbeknownst to Twilight, the Changeling Queen had injected her with a unique type of venom when she bit her, one that could reverse the pain receptors in every part of the Unicorn's body, forcing her to feel only pleasure, no matter how painful her experience should have felt. And with a little bit of Changeling magic, that pleasure would increase immensely.

Not only that, but as it continued to spread, her body was slowly being altered, allowing her to not only endure everything the Changeling Queen planned to put her through, but also prepare her for receiving the Queen's eggs

And now it had finally kicked in.

The Unicorn's body suddenly started to grow hot, not from pain, but from sheer arousal. The pain in fact had suddenly begun to disappear… being slowly replaced with tingles of pleasure coursing through her. 'Oooohhhh, this… f-feels good…?Why in the world did I ever consider asking my Queen to stop!? This feels wonderful!' Twilight then let out a gasp as the pain was completely replaced with a feeling of pure, blissful pleasure that Twilight didn't even know existed! She'd thought what came before had felt good, but it was nothing compared to this! "Ah! Ah! AHHH! Mmmm-OOOOHHH!! That feels so good!" She cried out, her Queen grunting as she pushed deeper, and deeper, and deeper… until she felt her marehood reach the hilt. 

Once the Changeling Queen was content with how much she had forced inside the Unicorn, she lowered herself down onto Twilight's back and whispered into her ear. "Oh my dear servant, we've only just gotten started~" After giving Twilight's cheek a playful lick, she then began to rock back and forth, steadily forcing her shaft deeper with each thrust. All the while the Changeling Queen let out soft moans of pleasure, relishing the feeling of her slave's tight pussy wrapped firmly around her thick cock. "Mmmhmhm… y-you should be grateful-unf! A-After all-oh! N-Not many of my victims have had the-gah-privilege of enjoying their t-time servicing me-ooohh~"

Twilight shuddered as she felt Chrysalis' ovipositor pumping back and forth, in and out, she could feel her lower body growing hotter as jolts of pleasure replaced what should have been agonizing pain. Eventually, Chrysalis started speeding up her thrusts, humping Twilight with so much force that the very force was physically bucking Twilight forward. "D-don't… D-D-Don't stoooop-AAAHHA!!!" She screamed as a surge of pure pleasure shot through her body, her inner walls tightening around the Changeling's shaft while lathering it with her love juices. "Ahn! Oh, my Queen! Keep going! Deeper! DEEPER!!! Oooohhh yes, right there! Yes! YES! AAAHHH!!" She begged as her Queen slammed her shaft into her harder with more force after every thrust, pushing another inch in before pulling back yet again. The Unicorn's body cried out for more as her Queen continued to thrust violently into her, the Unicorn's pussy juices now aiding the fluids with lubrication.

"Oh my lovely servant, you have no idea how deep I'm willing to go~" Chrysalis chuckled, levitating Twilight's back leg with her magic. The Unicorn looked down… and her eyes practically bulged out, she could see the very outline of her Queen's ovipositor inside her! Before she could even respond, Chrysalis' shaft curled itself upward, stretching out her skin even further.

Nervously, Twilight found herself lifting her hips higher, allowing the changeling’s shaft deeper into her orifice, rubbing her inner crevices on the way to her cervix, making Twilight moan louder. "Y-Y-Yesss… yes!! Deeper… d-deeeeepeeeer…" She pleaded, hyperventilating as it started to move again, slithered deeper inside while curling up some more.

"We're almost there my servant, just don't pass out on me, otherwise you'll miss out on an extraordinary experience." Chrysalis replied right before wrapping her hooves around the Unicorn and pulling her into a sitting position, spreading her legs… and then using her magic to hold Twilight in place as she started slamming into her servant at nearly twice her previous speed, thrusting so hard that Twilight whole body was bouncing up and down on her lap, the Changeling's ovipositor extending and getting deeper with every thrust.

"OOHHHH YEEEAAHH!! RIGHT THERE!! AAH!! OH Y-YES!!" Twilight screamed as her inner walls tightened around her Queen's shaft, squeezing around it as if her body was trying to milk it dry. The Unicorn's eyes rolled back, her tongue rolled out of her mouth, and her breathing became shaky and erratic as her whole upper body bounced up and down with every thrust. "M-MORE! Oh please my Queen, m-more!" She begged, her screams echoing throughout the room as she got so, so close to her first climax of the night.

Then suddenly, Chrysalis stopped thrusting as the tip of her shaft hit something; Twilight's cervix.

There was a moment of silence, the Changeling Queen remaining completely still, as if waiting for her brainwashed servant to beg for it one final time…

And then, the Unicorn let out a small, pleading whisper:

"Breed me."

Chrysalis' fanged smile became unnaturally wide as she slammed her hips upward, breaking through the Unicorn's cervix and hitting the back of her womb with enough force to make a very visible bulge.

"AH-GAAAAAAAAHHHHH!!!!" Twilight screamed wildly, her vision going completely white as she came harder than ever before, her love juices spraying all over her Queen's shaft as well as the bedsheets, drool leaking out of the sides of her mouth as her body writhed in pleasure.

Chrysalis was 95% sure that if it wasn't for Shining Armor's soundproofing shield, Twilight would have woken up half of Canterlot by this point.

"MORE! FUCK ME MORE! OHHHHHH! IT FEELS SO GOOD!!!" She panted and gasped as an orgasm rocked through her entire body, throwing her head back in ecstasy as the tip of Chrysalis' ovipositor continued to hit the back of her womb, stretching it with each thrust and giving her the most pleasurable experience she could ever imagine.

Having nearly become lost in the throes of sheer pleasure, Chrysalis could feel her inner organs shifting, preparing to release her egg into the Unicorn, the petal-like flesh at the tip of her ovipositor fully opened up and extended outwards as it was pulled back, sealing the entrance to Twilight's womb and ready to pump as many eggs into her as possible.

As Twilight felt the flesh-petals pulling against the walls of her inmost core, a flare of immense pleasure shot through her whole body tingle, her inner muscles tightening even more in response. Of course, this didn't stop the Queen from humping her servant, the feeling of Twilight's insides lovingly yet tightly squeezing around her ovipositor making it throb with pleasure as she grew closer to her own climax.

"Ahhh… y-your pussy feels s-soooo good… m-my eggs! I-I can f-f-feel them c-c-coming!!" Chrysalis gasped, the pleasure growing stronger with each thrust as she rammed her hips upwards, her first egg slowly emerging from the base of her ovipositor and up her shaft… followed by another… and another. "I… I'm gonna cum! I'm gonna pump every last egg inside you and knock you up!"

For a moment, Twilight could feel Chrysalis' suddenly growing bigger, stretching her marehood out… and the Unicorn found out why when she looked down and saw several bumps traveling up her Queen's ovipositor, each one about twice the size of a chicken egg. It was finally time! In a matter of seconds, Twilight would be carrying Chrysalis' precious eggs, keeping her young warm and safe until they were ready to hatch into a new generation of drones.

A privilege Twilight accepted with pride.

"Y-YES! B-BREED ME-HHHMMM~!! KNOCK M-ME UP! I WANT YOUR EGGS-AHHN!! I WANNA BE A MOMMY SO BAD!" Twilight begged, her screams getting louder as the speed of the Changeling's hips grew even faster, the thickness and throbbing of her Queen's shaft filling her with so much bliss that she no longer cared if the experience mentally broke her.

"OHH! H-Here it comes! M-My egg… the first of many! I-I'M C-CUMMING!!" Chrysalis gasped as her eggs traveled through her ovipositor, each inch it moved sending jolts of pleasure through her shaft. Now accompanying them were the very same fluids that she'd lathered up Twilight's love tunnel with, pumping it all directly into the Unicorn's womb until the first egg reached the tip of her ovipositor, which had remained fastened in place in its "blooming" form.

"HHRRKKK!! AGAHHAA~!!" Twilight could only pant and moan from the intense surges of pleasure. The Unicorn gritted her teeth as the egg stretched her marehood, writhing in pleasure as she felt them traveling up to her womb, stretching her cervix wide each time they passed through it. "HAH! HAH! HAAAAHHA~" She gasped in bliss, her heart soaring as the first egg was pumped into her womb, her vaginal walls squeezing her Queen's pulsating shaft as the second one was pushed in… and then the third… then the fourth… the pleasure became so good that Twilight couldn't even scream anymore, weakly moaning in pleasure at the feeling of Chrysalis' shaft pulsing with every pump.

Twilight could feel her womb starting to get crowded after the fifth one entered her, and yet she didn't care in the slightest, it just felt so good to have her womb stretched like this! To be filled with her Queen's eggs. "Uuhhnn~"The Unicorn moaned lustfully looking down to see her belly slowly bulging outward, shuddering at the feeling of the shifting bumps as the stream of eggs sped up, her belly growing more and more…

The Changeling Queen groaned as she felt the Unicorn's inner walls clenching down upon her ovipositor and eggs, having lost count of how many she'd pumped into her servant. She could, however, tell when the final egg had been laid, the tip of her ovipositor shrinking to its normal size and closing itself. "Mmmmph! Oooohhh that felt… incredible~" She sighed in ecstasy, her ovipositor slowly beginning to withdraw from Twilight’s womb, the very sight of her servant now filled to the brim with her offspring filling her with a small bit of warmth and pride. Not enough to make her actually care about the Unicorn, but just enough to give her comfort in the knowledge that she'd chosen the right Pony to be her personal broodmare.

Delirious with lust, Twilight moaned softly as the Queen's shaft popped out of her abused pussy, shuddering as she felt the eggs settling in her, feeding off of her love and absorbing her magic. It was a strange feeling, but still a pleasant one, to have her belly so full, so swollen, so… so perfect. And the fact that her beloved Queen had trusted Twilight to keep her eggs safe and warm, to protect and give them comfort… it warmed her heart, gave her a sense of… purpose. 'Yes… this is… what I was meant to be… a broodmare… my only purpose is… to be a mother, to care for… my Queen's offspring…' She thought dimly, letting out a blissful giggle as she rubbed her pregnant belly, she couldn't wait until the time came time to lay them. "Teehee… eehh-heh-heh-heh…"

“Mmmm, that was quite satisfactory…” Chrysalis smirked with pride as she pulled herself off the bed, glancing back at the resting, pregnant mare with a fanged smile. "The perfect host for a new generation of Changelings…"  The Queen mused before turning her attention to her obedient “Husband”, who'd been standing guard the entire time, blissfully unaware of what had happened to her little sister.

“Come along Shining, we have a wedding to prepare for.” Chrysalis chuckled as she casually trotted out the door while gesturing for him to follow, leaving Twilight alone with nothing but her thoughts of bearing her Queen's children…
