In the name of Science!

"Okay, everything is set! Now to just wait for their arrival!"

Thorax expected an entourage of armed guards, but what he got was far more simple, if a bit unorthodox. There was a sudden crackle of purplish magic and then poof! All four princesses suddenly manifested in a bright violet light that very briefly blinded him.

"Uggggh, that was... hard," Twilight Sparkle said as she held a hoof to her head which now throbbed in pain. "Next time, we'll just fly here," she slipped down and sat on her haunches. "Teleporting Cadence was one thing, but all three of you just makes that spell very very difficult to cast."

Princess Celestia gave Twilight a proud smile, "But you did it, don't let that accomplishment slip away just because of how hard it was. I can't really recollect any of us ever being able to teleport three alicorns." The Princess of the Sun giggled and was quick to add, "But then, I can barely teleport myself. Too scared of putting myself in a wall," she admitted before stepping away.

Princess Luna nodded in agreement of her sister's words, "It is true, Twilight Sparkle." She turned to face the Princess of Friendship and offered her an amorous grin, "Lets hope your pain quickly recedes, less you'll be the one having to do all the work."

Princess Cadence laughed, rubbing a hoof against the back of Twilight's head comfortingly, "I wouldn't worry, I know a few spells to renew one's vigor." She then leaned down and whispered into Twilight's ear, "Just ask Shining Armor, he knows all about it," then slipped away with a chortle to join Luna and Celestia who were approaching Thorax.

Thorax rubbed the back of his head in confusion, "Well, it's certainly nice to see you all again so soon." He waved a fore hoof toward the large table littered with delicacies of which mostly consisted of common, but finely prepared Equestrian dishes. "Sorry, we don't really need to eat, so I did my best," the changeling king murmured with a heavy blush.

Celestia curtsied and gave Thorax an approving smile, "It shall do just fine, King of the Changelings. It'll taste wonderful after we've finished business."

Luna nodded to her sister, then turned to Thorax, "Agreed, we should tend to the matter at hoof. I am quite sure the physicality of our affair will give us quite the appetite."

Thorax looked confused, straining to comprehend Luna's words. Twilight noted this and quickly jumped in to elaborate.

"She's talking about coitus... copulation," the lavender unicorn explained, but still saw the changeling king lost in a cloud. "Oh gosh, ... none of you told him?," Twilight turned to the other three princesses with a gawking expression.

Princess Celestia blushed, Princess Luna looked seemingly innocent and Cadence just giggled. None of them offered an answer or a reason why he wasn't informed.

Twilight took a very deep breath and stared into the very much stupefied changeling king's eyes. "Sex, we're going to have sex with you," she straight forwardly informed him in a monotone voice.

Thorax nodded, but then it looked as if he was about to be struck by a pegasus chariot in mid-flight as his eyes went as wide as saucer plates. "Oh... haha, I get it... that's.. that's a good joke, Twilight," he laughed with a stressed somewhat forced smile.

Cadence, with a suave smile and sway in her hindquarters, rubbed up against the changeling's side as she went by him. "Oh, she wasn't joking... old tradition, very old," she confirmed the truth. She used her hoof to lift that beautiful, but fragile looking tail and peek under it. As she saw the familiar puffy orifice, of which she was so well acquainted with due in part to several lust driven escapades, she licked her lips.

Thorax froze as he felt her advance, hoof moving his tail and practically feeling her eyes feasting on the sight of his light green wrinkly doughnut of an anus. He couldn't move, too lost as his mind raced to grasp the reality of what was happening.

Soon, the three other princesses had joined Cadence in exploring his body. They felt his balls, nibbled at the more sensitive bits where his exoskeleton was as tender and sensitive as flesh. They all were absolutely fascinated, much to Thorax's embarrassment, when they saw that thick periwinkle colored cock with all it's thick plate like ridges. By the end, Thorax surrendered himself to their motives and found himself leading them to his private bed chambers.

Twilight was the first to act, pushing Thorax to the bed so that the changeling landed on his back. "Changeling physiology is a mystery, but so far I'm quite impressed with my findings. Lets see how your stamina and endurance hold out," she smirked as she climbed on top and stared longingly into those deep opaque eyes.

Utilizing her magic, she guided the tulip shaped head of his cock as she leaned back. Her eyes rolled into the back of her head, the alicorn moaning in bliss as she felt his length stretch and fill her marehood. "Dash showed me this trick, lets hope you like it," using her hind legs and wings, she began to work herself up and down his cock. She'd flap her wings just as she reached the apex of what little lifting she could manage with her hooves, then allowed herself to fall and impale her marehood on the changeling king's cock.

Thorax groaned which each time he felt her fall briefly, her marehood squeezing tightly around his length as it was forced deeply into the hot moist depths of her orifice. His body reacted instinctively to the sensation of pleasure and began to thrust upward into her body as it sank by down and devoured his cock hungrily. "I... I'm going to cum," Thorax muttered, which only seemed to encourage the mare to breed him even faster! He gasped sharply as he felt Twilight's insides convulse as the mare reached her orgasm. He couldn't hold it back any longer as he let out a loud moan, cock throbbing with immense pleasure as he pumped the contents of his loins inside her.

Twilight was riding through the climax of her orgasm when she felt something strange and new. It was if she was being filled with something more.. solid and hard. "Oh gosh... he's... he's filling me with his eggs," gasped Twilight who stuttered as she tried to catch her breath. Her mind and stomach fluttered as she felt her womb being filled with a sensation she had never experienced before! By the end, there was a noticeable bulge as she dismounted herself. "Well... then.. that was fun," she surmised with a grin, rubbing a hoof along her now egg filled marehood. It felt good, like eating a full meal, but sexually fulfilling instead of sating hunger.

The other three princesses looked at each other then the bulge in Twilight that was King Thorax's eggs.

"Okay, that's definitely something I want to feel," Princess Celestia as the first to speak after Twilight Sparkle had her go at Thorax. "Princess Cadence, if you would?," she gave her a sly smile.

Princess Candence curtsied and her horn erupted in an aura as she started casting the spell. Her magic surrounded the exhausted changeling, seeping into his body and reinvigorating him with strength, energy and amplifying his sexual drive. "Don't worry, feels odd the first time, but you get used to it."

As if waking up from a full restful night's sleep, Thorax found himself suddenly willing and able bodied as he rolled over and rested on his stomach. "About those... eggs, Twilight. You can... um... just squeeze them out later. Changeling females have an inherent magic that fertilizes eggs. Don't think it works the same with ponies," Thorax smiled.

Twilight grinned, "Mhm, well I bet they'll feel quite good when they're coming out."

It was then Luna stepped forward, clearly asserting herself as the next princess to bed the changeling king.

Thorax cracked excitedly, "You know... I could get used to this."

Fly Me To The Moon

"No one but the Sun shows dominance over the Moon. So the same goes for even you, Changeling King."

With a wry smile, the Princess of the Night called upon a particular spell that briefly turned her into a silhouette of shining blue magic. After it had dispersed seconds later, Thorax looked over Princess Luna to see what precisely she had done.

"Umm... nothing change? Maybe it fizzled?," Thorax chimed in as he continued to admire the Princess from his bed.

"No, it was quite successful," she replied and then turned so that the side of her body was within the changeling king's view. Her hind leg lifted a bit, as if to give him direction.

It's then he noticed the obvious... the princess has used her magic to endow herself with the reproductive tool of a stallion! His cheeks went scarlet as the idea of what *Prince* Luna had in store for him filled his imagination. "I... I take it that's not just for looks, huh?"

The alicorn deadpanned toward him as she shook her head, "It is not. Now, present thy rump so that we may continue."

Cadence suddenly stepped in, eyeing Luna with a bit of a scowl, "Now wait a second. If you do that, I'm not going to be able to enjoy licking his tailhole. Not a fan of cream filled doughnuts, Princess Luna."

Princess Luna laughed, staring down Princess Cadence who now stood between her and Thorax whom was now laid out on the edge of the bed. His tail was to the side, baring himself before the Alicorn of the Night. "Oh... very well then, indulge in your queer fantasies. Just make to enjoy it, for I doubt his orifice will ever be as tight after I am done."

Thorax laughed warmly, "Oh wow, you want to... lick me there? I've ever only had one other do that," he wiggled his royal changeling rump excitedly. "Of this, I have no issues. So lick away, oh Princess of the Crystal Empire."

Cadence felt her face go hot as she blushed, she didn't expect her fancies to be so... appreciated. "Thank you kindly, King Thorax," she bowed before his rump. Once she stood up from her bow, she immediately set upon the changeling king with a voracious appetite. Her thick warm and wet tongue ran and traced around the puffy exterior before the tip addressed the tight dry wrinkle that was the orifice itself. She found it yielding, her palate getting served with the taste of heavy muskiness with a hint of dung that she so often enjoyed with her lover. Her tongue practically danced about, eagerly shoving her face into his derriere as her tongue dug deeper into his pliant backside. Five minutes afterwards, Cadence pulled away and took a deep breath of fresh air. "That was.... absolutely amazing." She eyed his puckered anus, rubbing her hoof against it tenderly, "I almost can't wait to see what it looks like after Luna has finished violating it."

Luna gave Cadence a thankful nod as Cadence stepped away with quite the satisfied smile on her face. "He should thank you. Your love for licking another's anus is a boon for him, for it will make penetration less painful."

Cadence flushed, wiping a bit of saliva off her lips, "I hope so. From what Celestia tells me, you're not the type to be gentle or caring when you're on top."

Luna leered at Celestia whom turned away and hummed innocently to herself, "Oh... is that so? Seems like I'll need to teach my sister to keep our royal escapades to herself when we get back." Luna moved and mounted Thorax, her modest sized pony cock bobbing about as she got herself into position. "My advice to you, Thorax, is to relax. This does not have to hurt, but only if you let go of any anxiety or fear. I may indeed be rough, but it is not my desire to hurt you."

Thorax nodded and took a deep breath as he felt the flat bulbous tip poke around under his tail. Submitting himself to another male wasn't precisely alien to him. He had allowed Spike to take him numerous times during his visit in the Crystal Empire. Though Spike was small, when not giving in to his growth inducing desire to be greedy. Ponies, on the hand, were pretty big regardless. The changeling king let out a sharp raspy gasp as Luna suddenly thrust forward. The initial penetration wasn't so bad, Cadence's tongue and spit aiding graciously as Luna's thick and long black shaft plunged into his derriere.

Her large nuts audibly clapped against Thorax's backside with each thrust of those strong equine hind leg muscles. Her moans of delight mixed with his grunts in a cacophony. Her velocity increased greatly over a short duration as she hammered her magical stallion cock into that regal changeling rear. She could feel his insides gripping her meat in a tight embrace as her cock found a home deep in the recesses of the changeling's backside!

Thorax grunted, his own cock throbbing with intense pleasure as Luna ravaged his royal ass. His mind was lost in an ocean of ectasy, a steady ripple of pleasure coursing through his loins as Luna's head rubbed and stroked his prostrate with every every time she drove herself into his loosened rear. He yelped in surprise as she gave one final thrust, slamming her cock into his ass as she let out the loudest moan ever. He could literally feel her stallionhood twitching inside him as she filled him with her copious white creamy offering. Thorax joined in a disharmonic duet with her as he reached his own peak, shooting several thick gooey ropes of deep purple goo that had the consistency of jelly into the bed sheet beneath him.

"I see, so changelings don't have sperm. This... strange substance must be used to aid in lubrication so that the eggs have a much easier time whenever a male fills up a female changeling with his eggs," Twilight was busy investigating the strange bodily fluid, collecting a sample in a vial.

Thorax gave her an awkward look, "Did you... did you really plan to do that? I mean... ponies don't just carry vials around with them." King Thorax was once again, feeling himself growing stronger and more refreshed under the care of Cadence's rather extremely useful spell. Far as the cum dribbling out of his gaping hole, her tongue was more than up to the job as it was exploring his insides again. The taste of Princess Luna's cum was like gravy on biscuits and only made her experience even better as she deeply rimmed the Changeling King as he relaxed on his stomach and conversed with the other three.

Twilight laughed it off, smiling with much embarrassment as she rubbed a hoof through her mane, "Well, I said I was curious about changeling physiology."

Princess Luna yawned, having dispersed her magical equipment and now settled for laying on the floor as exhaustion overtook her. She had turned down Cadence's offer to be rejuvenated. She was quite content for a nap while the others had their fun.

Princess Celestia shook her head once she realized her sister was asleep. "I hope she forgets about what you said or I'll not be sitting on my throne for the good part of an afternoon."

Cadence giggled nervously, "Oh yes... sorry about that." She then asked Celestia with a bit of curiosity after Celestia had mentioned the consequences. "Wait... Luna... does Luna spank you?"

Celestia bashfully nodded, looking down at the ground in a bit of shame. "We can't exactly let other ponies help atone for our mishaps... so we're each others' disciplinarian. More often or not, I find myself offering my derriere for her, but I think a part of me does it on purpose."

Cadence nodded slowly as she took that tidbit in and chewed on it for a moment, "So what you're saying is... you get off on Luna punishing you." When Celestia quickly shushed her, she just giggled at the revelation.

"All right... my turn," Princess Celestia arose from the spot where she was laying.

King Thorax smiled and nodded eagerly, "Given what I know... and what I just found out in the last minute or so, I suspect one of us might not be sitting by the end."

Celestia groaned and eyed Cadence with an eye filled with spite, "Well, the surprise is ruined, but I'm sure we'll both enjoy ourselves nevertheless."
