After a birthday celebration the royal house will not soon forget, Princess Cadance is left pondering the ethics of it all. A trio of guests is about to share with her the depths of her aunt's heart, and send her home a few tricks wiser. (Part 3!)

It was a birthday celebration unlike any other for the crown princess of Equestria, and one the royal house, at least, will not soon forget. Now, as the shadows of Canterlot grow long and the scents of Celestia's favorite desserts wane from bakery windows, the Crystal Princess is left pondering the ethics of it all. Is this who the aunt that kept such a wizened eye on her niece growing up really is?

A clandestine visit from a trio of guests is about to make a new woman out of Princess Cadance, and in so doing, instill in her a deeper understanding of her dear aunt's heart. With the promise of a night as memorable as the day that preceded it, Cadance might even head back home with a few new tricks up her sleeve...

1 - Knowing Her Heart

Celestia’s grip upon the sky was waning.

Princess Cadance watched the sun for as long as her eyes would allow, looked away, and then glanced back again. The orb of day was right on schedule, towards its final approach with safe harbor behind the western mountains. There was nothing particularly remarkable about the phenomenon, but Cadance found herself staring at anyway, until memories of earlier days in which her wizened Aunt Celestia admonished her for looking too long came to mind. Cadance knew as well as anybody that staring into the sun could have adverse effects on the eyes, but the warning seemed somehow diminished now...as though the source was no longer a respectable one.

Cadance glanced down at the long shadows of Canterlot. Banners depicting her aunt’s birthday were still flapping with life, and the scents of Celestia’s favorite treats still came to her from bakery windows, carried upon the late-day breeze. Citizens milled about in various states of merrymaking from carousing to romantic strolls, and the young scurried about at their games of wooden swords and imaginary beasts. Cadance focused on the children, picturing herself among them in a time before her brow had been made heavy by the burdens of an empire. She might even have seen herself in a few of the adult faces below the high tower of her guest apartments, had so many of the citizens not spent the day going on about the crown princess’s body in such shockingly casual ways.

The crystal princess tilted her head. She had been told about the spell upon the populace, and that it was but temporary with the day. But as of the moment in time she laid eyes upon them, it was disconcerting to know that every single soldier, commoner, and dreg about the city was as familiar with Aunt Celestia’s naked contours as they were with their own.

A light knock, feathered with the back of the knuckles, broke her reverie.

“Cadance?” A familiar voice called from beyond the heavy oak of the main entrance. “Are you here?”

Princess Cadance shook off her befuddled thoughts, cleared her throat, and rose from the coffee table near a grand collection of viewing windows to take note of herself in the mirror. She had yet to remove her traveling clothes, and was still clad in a rider’s scarlet skirt, a white blouse, a sturdy black belt, and a baldric depicting the seal of her empire. She hastily removed the baldric, hung it upon the back of a tall chair, and beckoned to the solid door.

“Yes Twilight, I’m here. Please come in.”

The chamber door for distinguished visitors creaked with disuse. As it receded, Cadance found her sister-in-law, Twilight Sparkle, standing too far away in the hall to have been the one to knock. Celestia’s understudy appeared quite different from the last time Cadance had seen her. Standing there mousily, her eyes darting in every direction but ahead, Twilight was rocking on the heels of soft slipper-shoes and idly whistling. She was clad in a formless and rather normal looking yellow sweatshirt over black yoga pants, as though she had donned whatever garb happened to be lying around after hurrying out from the bath. Twilight’s raspberry-violet locks spilled freely over her shoulders to the small of her back, but the unseasonal outfit stole a measure of their grandeur - it was as though Celestia’s student were trying to hide something.

At the forefront of the procession, the back of her hand still raised to the door, was the enigmatic Princess of the Night. Luna’s outfit was chaste but left less to the imagination, for the curve of her ample bosom followed the contour of the flowery tank she wore quite closely. Cadance noted the night-patterned sweatpants and slippers that suggested Luna was not preparing to make a sojourn into the dreams of her subjects on this particular night. Luna wore a thin silver tiara and bore a black satchel looped over her shoulder that gently smacked her hip whenever she moved. Her expression was calm but piercing, and Cadance was momentarily awed by it.

The awestruck younger princess found herself doubly so when her eyes fell upon the third of her three visitors. Aunt Celestia, who had guided her through the years of her youth with patience and calm, stood behind her younger sister in a state of utter debasement. Celestia’s posture was that of a servant - eyes averted, feet together, and back stiff, as though preparing to step high to her next task. Her pastel hair wove a slow and beautiful pattern around her like always, but she was without the marks of her office...or anything else, for that matter. Celestia’s creamy pale flesh was on display from head to toe, from the jiggle of her free-flowing breasts to the supple curves of her round hips. Her cheeks were flushed and she made a gesture to cover her nipples with one arm when she saw Cadance, but Twilight touched her arm and shook her head, a knowing look in the student’s eyes. Celestia let the arm drop and stood up straighter, pushing out her chest for a proper display. The only accessory upon the crown princess’s body was a collar of midnight blue. Constructed of leather soft enough for prolonged use, the item was nonetheless affixed tightly to Celestia’s throat, and bore a tag with the symbol of her sister in the manner of a dog’s identification. Cadance could not tell if there was a clasp in the back, but the collar did bear a single silver ring, to which was attached a short leash of the same color and material. This was held by Princess Luna, who twirled it about her fingers absently as she made her address.

“Good evening, Princess Cadance. You are of course well met.” Luna glanced at the sturdiness of Cadance’s attire. “Have there been any difficulties settling in after your journey?”

Cadance made an exasperated face, wondering if Luna could possibly be serious in asking such a question. Words failed her, but she was a trained royal nonetheless, and found a few to offer straightaway.

“No, no of course not,” she paused, unable to remove Celestia from the corner of her vision. “I just...haven’t gotten settled yet, that’s all.”

Twilight looked eager to insert herself into the conversation. She opened her mouth, but Luna shushed her with a simple look and let herself into the room, her entourage in tow. Luna nodded at Twilight to close the door, but kept Celestia nearby on a short leash. Upon the nearest table was a bowl of fresh fruit, and Luna helped herself to a nectarine whilst enthroning her lithe body upon a posh couch before the cool hearth. Celestia merely followed her sister in silence, and stood beside the couch like a lady in waiting.

Cadance turned her attention back into the room and her elder visitors. She continued to battle for words, but stiffened when she felt two hands on her shoulders from behind. Breath was quickly thereafter upon her neck, bringing with it the merry voice of the only one in the room younger still than she.

“Isn’t this an amazing celebration?” Twilight offered amicably. “I mean, the royal birthdays always are of course, but everyone seems even more...excited than usual, don’t you think?”

“I...you could say that, yes…” Cadance replied, and then sardonically: “I can’t imagine why…”

Twilight didn’t take the bait. She only giggled and pressed a small, unabashed peck into her sister-in-law’s cheek. She then scampered to the couch and situated herself in a comfortable position two cushions away from the Princess of the Night.

Cadance tilted her head and considered the lighthearted countenance of Celestia’s student. Twilight wasn’t a particularly downtrodden person, but Cadance couldn’t remember a time when she’d seen the girl so lively, as though she were having a regression into the flower of her youth. With little else to say or do, Cadance approached the hearth area and found a perch upon the cozy loveseat that sat opposite the occupied couch. She paused there, waiting; curious as to what her visitors might do next.

Luna and Twilight were exchanging lighthearted bits of conversation. Luna paused, taking note of Cadance, and then tugged sharply on Celestia’s leash, addressing the elder princess without looking at her.

“Down.”

Celestia’s cheeks were as volcanic fire, but she made no further move to cover herself, nor did she hesitate to obey. Lowering herself to her knees upon the rug, she came up beside her little sister and accepted a pat on the head from Luna that was much akin to a beloved animal.

Twilight observed Celestia’s posture. “Oh, did you want to--?”

Luna shook her head as she twirled bits of her sister’s hair through her fingers and finished off the tender fruit she had been eating. “Not yet. We have much to discuss with our guest first.”

“Oh geez, right! Cadance probably thinks we’re planning a coup or something, heh.” Twilight flopped back upon the couch and grinned sheepishly at Cadance. “But anyway, did you see all the banners? There have to be at least ten percent more this year. Well, that’s what Fancypants said anyway, but I assured him that there are actually only 9.83% more banners this year. I should know because I counted them all.”

Cadance didn’t doubt Twilight’s figures for a second. She watched as Luna began to stroke Celestia’s cheek, cupping her chin and forcing her to look up for eye contact.

“But that’s still pretty impressive, right?” Twilight went on casually. “And I have to admit that I wasn’t sure about all this at the beginning, but you know? Everyone seems really happy and relaxed today. That’s what they’re going to remember, having such a nice day, and I guess if the spell leaves them with just that, it’s probably okay just this once.”

“The spell,” Cadance seized her opportunity to speak up, “would you care to explain that?”

Twilight looked oblivious. “Didn’t I tell you about all that earlier?”

“You told me about the enchantment on the people, yes, but,” she glanced at Celestia, “did you enchant Aunt Celest--?”

“No.”

Luna belted out the single word with such authority, all eyes turned to her. Her expression was grave. “If you are about to ask if my sister is under a spell, the answer is no, nor would I do such a thing to her on her birthday, or at any other time without her consent.” She patted her thigh, and Celestia rose up upon her knees to linger there. “And if you are concerned that I might be duplicitous, Princess Cadance, you need but scan my sister for the presence of magical influence. It is a spell I know you are capable of, and I will not stop you.”

“I...didn’t mean to suggest--”

Luna smiled. “Of course you did not. But you are still unable to accept the idea that your eldest aunt has needs, developed over time by a thousand years of sole rulership over a kingdom meant for two.”

“I…” Cadance considered this. “...needs?”

Luna reached out and calmly began to stroke one of Celestia’s voluptuous breasts. The sun princess sighed softly and arched her back, pushing her chest into the grope. Cadance watched as Celestia’s nipples began to slowly tighten - her body’s indication that the contact was welcome.

“Indeed,” Luna finally confirmed. “My sister has needs that I once saw to in an age long before your birth, but was unable to continue for...unfortunate reasons.” Luna shifted uncomfortably, glossing over the topic of Nightmare Moon. “My dear sister went on for a millenium without the release she required, from the one person she could trust to give it to her. Now that we have reconnected, however,” Luna glanced at Twilight, “my sister has been able to find bliss in a whole new world of what was formerly only for her and I.”

“She wants this,” Twilight chimed in as she scooted over to fondle Celestia’s other creamy bare breast. “She wears a crown too much, and she wants to be ours so much that once she admitted to it, the rest just came naturally.”

Cadance watched the physical exchange. Celestia sighed again. The sound was honest, pure - like those that Cadance herself uttered in the private throes of her husband, or those she had heard in the hearts of lovers she had helped bring together with her powers. Cadance knew the sound well, and it opened her mind to the possibility of what stood before her now.

“Oh,” Twilight perked. “How about now…?”

Luna nodded and tossed the satchel onto the couch next to her. “Yes, now is a proper time.”

“...can I use mine?”

Luna grinned and nodded. “Very well. Indulge yourself.”

Eagerly Twilight rummaged through the bag until she came up with a device even Cadance recognized. Stiff yet pliable and constructed of an outer membrane resembling the texture of flesh, it was an insertable toy in the shape of a thick penis. Cadance knew it was a specimen of quality, for she recognized the stain-resistant material and the mark that denoted internal clockworks that a mage could use to make the entire device vibrate. But she was not expecting the rest. The penis was purple, striped once in a color like Twilight’s hair, and bore her personal mark emblazoned on the side.

Twilight caught the toy in her magic and levitated it before her, explaining as she showed it off. “I just had it made. It wasn’t hard to crunch some numbers and do some theorizing based on my genetics. If I had been borne a man, this--” she poked it once with an outstretched finger, “--would have been my exact proportions. So it’s about as close to a representation of my own penis as you can get without conjuring up one.”

Cadance was shocked. “You...made a mold of your penis when you don’t even have a…?”

“Yep!” Twilight sang. She bent close to Celestia and levitated the toy to a standing position on the rug. “I did it for our favorite pet, who I know just loves the idea of having the real me inside her, don’t you, Pet?”

Celestia had her eyes on the toy. “Oh yes, Mistress. It gives me such pleasure to know you can take me with the real you.”

Twilight smiled merrily. “Good. I bet your knees are getting sore, slut. Sit down, the way you were taught. The way that’s best for you.”

Celestia moved with deliberate slowness. She crawled to the toy and stepped across it, bending her knees to straddle. Luna shook her head and pushed on Celestia’s side, encouraging the elder princess to turn until she was fully facing Cadance. The pet then began to lower herself slowly upon the toy. Twilight’s proportionally-accurate penis split Celestia’s already engorged folds and began to claim her. Celestia sighed and cooed, the toy sinking deeper, until her bottom was resting on her legs and the toy was tickling her cervix.

Twilight giggled. “She always sighs a certain way when I’m all the way inside her. It’s because she knows that my real penis would have been long enough to touch all her secrets.”

“Nnh...yes…” Celestia muttered.

“Of course it would have,” Luna remarked. “Our pet is a debased and inadequate whore, after all. The lowliest of our guards could not only pierce her to her deepest places, but drive her quite easily to cries of pleasure that all could easily hear. And that would be before he really even gets going. Tell her, Pet.”

“T-tell me what…?” Cadance asked, bewildered by the sight.

Celestia began to piston her knees, allowing the toy take her in the way she knew her mistresses wanted to see. “Mistress Luna...g-gave me special time with the g-guards...they all made me cum so much…”

“Even the young clumsy ones drove her wild,” Twilight commented. “It was adorable.”

“Aunt Celes-” A sudden premonition that addressing Celestia directly was the wrong thing to do hit Cadance, and she redirected her attention to the couch.

Luna was caressing Celestia's cheek from behind, eliciting an affectionate nuzzle from the slowly bobbing princess. She replied to the unspoken question in Cadance’s eyes. “When properly primed, your aunt's debasement knows no bounds.” Noticing Cadance’s confusion, she amended: “Fear not. She is as much the crown princess of Equestria as ever you have known her. In my return, she has merely found recourse to be once again herself in private. My pet.”

“And mine too!” Twilight chimed in, looking on the verge of giddiness as she watched her mentor play. “She likes belonging to her student. Don't you Pet?”

Celestia was fondling her own breasts as she bobbed. She bit her lip, forcing herself to stay below the threshold of release, as she knew her owners wanted. “...hahh..y-yes my m-mistress…”

Luna levitated two tangerines from the fruit bowl, offering one up to Twilight. It was a subtle signal, one the student of her sister picked up on, and the two of them used their snacks as an excuse to fall silent. Patiently they waited for the moment they knew would come.

Cadance’s attention inevitably fell to the proverbial elephant in the room. Her aunt, Crown Princess Celestia, was there upon the floor, impaling herself on a thick violet dildo. The base of the toy had a wide taper such that it seemed the princess could not quite take it all in - Cadance’s eyes shifted to Twilight just for a moment, as she wondered if the student had embellished the numbers just a hair.

Celestia let out a sharp whimper; the sound was punctuated by rhythmic squishes that became more prominent by the minute. She was facing Cadance with her body in full view, and had her eyes dutifully on the younger princess. Celestia was fondling herself still - pinching her nipples and running her hands all over her creamy white front, gracing herself with light strokes over the more unorthodox tease-spots - forearms, undersides of the wrist, and along the taper of her tummy. Luna knew them all, and she insisted her pet didn’t ignore them - it would not do if Celestia weren’t seriously edging herself.

Cadance sat and watched for several minutes, her every expression dutifully recorded and remembered by her two clothed visitors. Her brow was working back and forth between confusion, uncertainty, and of all things...curiosity. It was the last of the three that Luna was waiting for, and when she finally saw it manifest, she leapt upon it.

“Pet,” Luna said simply, “does it please you to have your niece’s eyes on you in your throes, as those of the rest of the public have been this day?”

Celetia could scarce reply. She attempted it once, and managed nothing but a mouselike squeak until she was finally able to produce a few grunts. “...mmh...mmhmm…”

Luna’s eyes went back and forth between Celestia and Cadance. The latter seemed stiff, but she had yet to express true misgivings or demand an end to all of this. On a lark, the Princess of the Night hatched her plan.

“You would like to serve your niece, would you not, Pet?”

“Nnhh...mmhmm…”

“Then hop to your duty. Show your little niece what you fantasize about.”

Princess Celestia required little encouragement. Her only misgiving was that the toy inside her would not come along for the ride, for her walls were far too slick to hold it, and her mistresses had not seen fit to keep it there by magic or restraint. She got up upon her fours, gazed lovingly at the wet toy behind her, and crawled along the rug until she was looking directly up into the eyes of her niece.

Cadance cleared her throat, stiffening as she felt her aunt’s hands upon her thighs, running up the length of her skirt. Celestia’s expression was contrary to what she was doing - she kept the eyes of a familiar matron upon her skittish niece, soothing the younger into complacency. Cadance sat without the comfort of those upon the couch, but she allowed Celestia to part her legs and hook her fingers around the lacy panties beneath her riding skirt. The younger princess’s cheeks deepened with color as she felt the sheer fabric sliding down her thighs, and so captivated was she that she scarce noticed Celestia’s encouragement to pass one leg through. With the undergarments helplessly trapped around only one of Cadance’s ankles, Celestia kept eye contact and a soft smile until her visage vanished under the folds of the sturdy skirt.

Cadance jumped when she felt the probing touch of something moist below. Uncertain where to look, her eyes fell upon the couch, where her aunt’s owners lounged. Both of them had finished their fruit, and neither looked at all uncomfortable with the situation. Twilight sat with a lax posture that Cadance might have attributed to the student’s friend Rainbow Dash, and bore upon her lips a smug smile to match. Luna sat tall, her expression neutral, but her eyes were firmly rooted upon the taboo mission she had sent her elder sister on.

Luna calmly cocked her head. “Something vexes you, Princess Cadance?”

Cadance could feel fingers spreading her below as the wet probing continued. She cast several glances downwards, but could see nothing beyond the scarlet of her skirt. “...I...I...uh…” The voice of the youngest princess was that of a shrew, “...this...I…”

Luna cocked a seemingly disinterested brow down at Celestia’s protruding, naked rump. “Have you never sought ‘service’ from those who live under your rule?”

Cadance looked mildly shocked. “I--I don’t do things like that!” “I-it’s not that, it’s...just…”

Luna held up a hand. “It is just...what?” She asked of Cadance. “You are a ruler, used to command. Speak your mind.”

Cadance let out a breath and failed to restrain a shiver that ran from her loins up her spine. “I-it’s just that...Princess Celestia is...she’s my aun--”

“She’s my pet,” Luna corrected. “And she is showing you her eagerness to serve. It is her wish to do so--” Luna stroked Twilight’s thigh once, “--as it was her wish to serve her student.”

Twilight had her eyes on Celestia’s jiggling backside. She addressed Cadance: “Mmh...you know I wasn’t sure what to make of it either at first, but...just let it happen for awhile. You won’t be disappointed.”

As if on cue, Celestia found Cadance’s button and began to tease it. Worn still by a day’s ride, the latter found herself sighing softly, her eyes trying in vain to peer around her skirt.

“Here,” Luna said, “I will show you what you do to her.”

With that, Luna was off the couch and on her knees by her sister’s side. She took Celestia’s hands away from their perches underneath Cadance one-by-one, and touched the crown princess’s wrists together against her lower back. Glancing about, Luna’s lip turned up in an amused grin as she caught Cadance’s own hanging baldric in her magic and floated it over to bind Celestia’s arms tightly behind her back. Satisfied with her work, Luna nonchalantly inserted two fingers into Celestia’s womanhood and spun them around, drawing forth a muffled gasp from under Cadance’s skirt.

“Do you hear the wetness?” Luna instructed Cadance, calm eyes meeting wavering ones. “Did my pet appear aroused to you when she walked in? This is how quickly helplessness affects her - how eager she is for it.”

Cadance’s breathing had deepened. “I...I just can’t be-believe that...all of this…”

Luna nodded at the skirt. “You have cast too many glances at that to make me believe you do not desire to see what lies underneath. Go on, move it.”

“I…”

“She wants you to move it,” Luna insisted. “My pet wants you to see what a good girl she is. Do you not, Pet?”

Luna slapped Celestia’s backside hard, eliciting a whimper and a murmur in the affirmative from beneath the skirt.

The crystal princess’s attention was affixed to the scarlet lump between her legs. Part of her wasn’t certain she wanted to see her aunt like this, but the hardened nipples beneath the whiteness of her blouse were telling and plain to see. The licks were long and deep, punctuated by quick flicks over the little button of Cadance’s love, and despite her hesitation...they were having an affect. It was as though her aunt knew her body as well as her heart, and Cadance found herself slowly peeling back the skirt to greet her benefactor.

Celestia worked, her nose and mouth buried between Cadance’s legs. She opened her eyes and rolled them up to her niece as she made a show out of taking a deep breath of Cadance’s awakening scent. Her tongue slipped deeply into the younger princess, lapping and swaying in time to Cadance’s stifled grunts.

“You’re holding back,” Twilight said gently from the couch, “but you don’t really want to, everybody here can see that.” She fell silent then, her attention lost in the play.

Luna arched a brow at the student of her sister. Twilight’s grin had taken on a dreamy connotation, and the Princess of the Night knew the student was as primed as her mentor. Like a dark spring she rose from the ground and flowed over to the couch, where her willowy arms surrounded Celestia’s student and drew her close. Luna took Twilight under the chin by one finger and drew her in, until the student’s eyes had no alternative but to lose themselves upon the waves of the night before them.

“You think that you can merely voyeur,” Luna whispered. “You have become cocky, Twilight Sparkle. Perhaps it is time that you remember your place as well.”

Luna drew Twilight into a rather chaste kiss, but it was enough to take the edge off the student’s uppity mood. With Twilight’s chin still in her hand, Luna held her eyes front as she wormed her other hand under the mortal’s sweatshirt. She felt about, satisfied when she got a nice handful of warm, soft breast.

“I see you are clad appropriately,” Luna cooed.

Twilight sighed, eagerly resigning herself to the removal of her top, which would inevitably show off her lack of a bra to the room. To her frustration, the night princess didn’t accommodate. Instead, Luna spun the smaller girl about in her seat and drew her close, depositing her between the larger span of Luna’s legs. With Luna’s breasts mashed up against Twilight’s back, the moon kept up her groping under the student’s shirt, but slipped her other hand down the front of Twilight’s pants.

“You want to watch them, don’t you?” Luna whispered. “Your mentor and your sister-in-law, you have desired this for some time now, I suspect.”

Twilight, who had far fewer reservations about the situation than Cadance, bit her lip and whined as her eyes fell on Celestia’s naked rump again. “...y-yeah…”

“Your slickness below suggests as much,” Luna said softly as she passed the threshold of Twilight’s panties and began to finger her. She peppered Twilight’s jugular with butterfly kisses, savoring the pumping of blood against her flesh, and drew up to her ear to nibble at it. “Watch them then, my student. Watch your sister as she watches you. Do not forget that your mentor is yours by my grace only, and you are both mine.”

The spectacle from the couch was unavoidably in Cadance’s field of view. Her eyes darted from the breakfast nook to the ceiling, but they always came back to the machinations upon her younger sister-in-law, and ultimately upon her aunt. Celestia’s arms were bound, but she had become so lost in her licking that her entire body was undulating with the movement, and her moans were nearly at the intensity of Cadance’s herself. The arousing distractions were causing lust to build up inside the youngest princess until it threatened to override her reasoning, and Cadance had parted her legs twofold to welcome more without so much as realizing it.

Princess Cadance’s head was swimming. She took her eyes off of the sweaty form of her aunt just long enough to glance at Luna, who had yanked Twilight’s top up to just above her modest breasts and her bottoms down below panty level. Luna was groping and manipulating the writhing little girl between her legs blatantly, and with a grin in Cadance’s direction, she kissed the top of Twilight’s head.

Cadance acted on the suggestion instinctually. She placed both her hands roughly on Celestia’s head and pressed the elder princess close without thought for her comfort. With a sharp cry that betrayed all of her desire, Cadance stiffened with release, arching her back and shoving her scented loins into Celestia’s face even as she pushed her nose farther inside. When the wave of desire began to ebb, Cadance collapsed upon the loveseat in a delicious fog. Without thought she placed a hand upon the sun’s forehead and shoved Celestia away, who crumpled instantly to the floor.

Luna had a whimpering student in her grasp, but she by contrast was quite calm. “I always knew you had it in you, Cadance,” the night chuckled. “Even now you have begun to treat my sister as the debased thing she most desires to be. I suspect the role that places you in comes more naturally than you are wont to suppose.”

Cadance, her legs lewdly parted and her engorged pussy lips on display to all, was staring at the ceiling. “...ahh...hahh...that...that was…”

Luna pinched one of Twilight’s nipples just to make her gasp. “Scandalous? Depraved? Alluring?”

Cadance made no distinction between the terms. “...nnh...uh huh…”

Luna lifted Twilight’s arms and slid her sweatshirt up and over her head as though the movement meant nothing, allowing the garment to fall behind the couch. Twilight’s breasts were perky and heaving, with two sweet caps of arousal topping each like a cherry. Luna fluffed them, presenting them to Cadance, and reached back down to fondle beneath the basic black panties the student wore. “You see how easy it is to make the willing yours? The ones who are overworked, underappreciated, drowning in responsibility, and in need of what you can give them?” She smacked Twilight’s chest, causing Celestia’s student to wince yet still push herself out for more. “They beg for it. And there are few bounds.”

Cadance glanced at the rug. Celestia was lying on her side, panting as though she had experienced as much release as her niece. She met Cadance’s gaze but said nothing, offering only a weak, submissive smile.

“She waits for you, Princess Cadance,” Luna said simply. “She waits for you to give her what she desires, and to seek your own desire in so doing. You cannot say you have never wanted to exert yourself over one of the only people in the entire land who ever had authority beyond yours.”

Cadance’s mind filled with the seeds of each thought until they began to sprout. There was a rustling noise as canvas, and the sound of something metallic clattering beside her seat. She looked over, and came upon an ornate necklace of onyx and jet, with a holographic pendant in the middle.

“Detect it with your magic,” Luna encouraged, “and know what it is capable of.”

Cadance barely had the wherewithal to produce a spell, but she summoned up enough concentration to target the necklace with some simple scrying. She was used to battling with some ancient artifact of the Crystal Empire that did not want to give up its secrets, but this item declared them boldly, and in an instant she was able to discern the purpose of the device.

Celestia, recognizing the trinket immediately, practically squealed with glee. Cadance laced her fingers through it and lifted it, examining it in awe until she found herself looking straight through it at Luna.

Luna grinned as she stroked her young lover, “You must have wondered how it feels for your husband. The power. The confidence as he...claims your womb.”

Cadance merely swallowed in response, her eyes darting between the facted trinket and the prone form of Celestia, who had gone back to dutifully averting her eyes. The crown princess’s hands were struggling against her bonds, and Cadance wondered how desperate Celestia truly was to play with herself right there on the floor.

Twilight whimpered, and when Cadance looked back, the student had nothing left but her black bikini-cut panties, which were looped around both thighs and restraining her from opening her legs any farther. Luna gave the poor trapped girl no quarter, and had by then two fingers inside her to the knuckle. The night princess remained infuriatingly silent, refusing to provide Cadance with any additional conversation that might result in stalling.

Cadance was left with nothing but the moment, and her intolerable state of arousal. She glanced into Luna’s eyes and could tell this had been the plan of the moon from the very start. With a quick breath that she held in, Cadance whipped the necklace over her head, and Luna’s hologram did its work.

It was like nothing the Crystal Princess could recall having felt before. Cadance had once cast a spell to turn herself into a man as a Nightmare Night costume, but she had replicated only the shape and structure of one - not the sensations. Now it felt as though she were growing an entirely new sexual core to compliment her own, that made its home in a beacon somewhere several inches away from her main body. Desire in reverse flooded her brain with such force it nearly staggered her, as she made a vain attempt to separate the want to be filled with the new need to do just the opposite.

Luna parted Twilight’s netherlips and presented them to the confused young princess. “This soft place is mine,” she commented, “but I offer you another, to slake your new thirst.”

Twilight’s heart fluttered, causing her womanhood to pulse, gaping and slick; waiting to welcome someone inside. In that moment, Cadance found her stride.

The matron of the Crystal Empire was not like Luna or Twilight. She had lands of her own, just like her aunt, and was used to being in command of them. The difference was that while Celestia had been in control for so many years that it had worn on her and given her need for release, Cadance’s sun was still barely rising.

Cadance couldn’t have said what exactly she had done with her clothes, but she slid off the couch and came up on her knees, her body bared for the room to see. She lightly stroked her erection, marveling at the shock it sent through her from the mere dance of two light fingertips, and loomed over Celestia.

“I shouldn’t have to roll you over,” Cadance said sternly to her aunt.

Luna grinned.

Celestia marveled at the new erection that bobbed above her, attached to the young lady with arms akimbo that was once the niece she kept close watch over. She squirmed, intending to come up on all fours with a presented rump, but Cadance whacked her behind with a sternness that suggested the younger princess had at least some experience in the privacy of her marital chamber back home.

“Not like that,” Cadance said sternly, “the other way.”

Celestia murmured her assent in a mousey voice and fell upon her back. Legs wide, she presented herself to her niece, who savored the moment as she ran her eyes over the crown princess’s prone form. Celestia was sweaty, soft, smooth, and wet in all the right places, her ever-waving hair undulating beneath her. Between her legs was a soft place - a channel that yearned to be bred by her young niece. Cadance leaned over her aunt with deliberate slowness, stopping short of penetration just to enjoy the sensation of bulbous head against wet slit. Celestia whined, and the music of it encouraged the younger on until she had planted her hands to either side of Celestia upon the floor. With their eyes locked together, Cadance slid home, her fat tip brushing aside moisture-weakened pussy lips.

The shudder that ran through the crystal princess was telling. It rolled along her spine and stiffened her like a boy learning to touch himself for the first time. As Cadance began to build a clumsy rhythm, princess Luna grinned and addressed her captured prey.

“Watch them, Twilight Sparkle. Watch your kin take your mentor.”

Twilight had taken over the toil of fondling her own breasts. She fidgeted, but found her legs still maddeningly bound by the panties that Luna had subtly slipped further down the captured student’s thighs. Draped upon her mentor’s sister like a damp towel, Twilight let out a series of hot pants and settled against Luna’s breasts, mashing them further into the moon’s tank top. Luna bit gently into Twilight’s neck, holding her prey there with a series of licks, and pulled back, only to nudge her sister’s student forward.

“You believe we came here only to encourage Princess Cadance. You are wrong. My plans are always greater, and I desire a show. Go to them.”

Twilight knew she was going to end up naked in the guest chambers one way or another, but she did not expect to feel the exposure on such an emotional level. Luna had edged her quite on purpose, and in a haze of desire she stumbled on bare feet across the rug to the coupling lovers, as an oasis in a nicely-embroidered desert. When she arrived, Twilight found that she had no plans other than to sit upon her knees and marvel by Celestia’s side. The scene fanned Twilight’s flames until she pulled Cadance into a rough kiss, coupling it with a glancing caress of Cadance’s perspiration-mottled cheek. Below, Celestia laid eyes upon the first kiss shared between her student and niece, which brought forth in her an undeniable whine of glee.

Twilight broke the kiss and scooted around Celestia’s head, placing her knees to either of the crown princess’s temples. Her upside-down image flashed in Celestia’s eyes. “Did you like that, Pet?”

Wet papping sounds coincided with the bounce of Celestia’s head. “...nnnh...mmhmm…”

Twilight, a measure of her composure rekindled by the closeness of her teacher-turned-pet, sported an almost wicked grin. “Only a dirty slut like you would think something like that, but then, we know how much you want to put everybody who’s beneath you on a pedestal.” She toyed with Celestia’s hair, wrapping a lock about her finger. “You’re just going to have to use your imagination from here on.”

With her words, Twilight rose up on her knees and shifted forwards, until Celestia’s vision filled with the tightness of her student’s rump. Twilight then slowly sat, enthroning herself upon her mentor’s face. Celestia, rendered blind, took a deep breath of arousal and held it as she plunged her tongue into her student, eager to show just how excited she really was.

Twilight blinked at the ceiling. “...mmmh, I never get tired of that...it feels like it’s been ages since I did it without a cock…ahh…” She rolled her hips, bucking at Celestia, “...d-do a good job, Pet, and you’ll get to breathe…nnh…”

Princess Cadance, with a view of little but her in-law’s midsection, pumped into her aunt with abandon. The new sensations were just that, and her elementary command of them brought forth inside her a desire to mate akin to a peaking youth. Her thrusts were without finesse, but they had behind them raw want, and she quickly found herself riding the undulating waves of the shuddering body beneath her. She might have reached her limit then and there, had it not been for her husband’s sister, who threw off her rhythm by yanking her up and drawing her into a sublime hug.

Twilight ran her hands all over Cadance as the two matched bobs. Her caresses about Cadance’s hips and breasts were insistent, as though the little sister was laying her own claim to her brother’s property. Twilight pushed Cadance back and confused the needy movements of her hips, confounding her more with pinches at Cadance’s nipples and appraising gropes of her breasts.

“Mmm...you know I always wanted to touch these…” Twilight whispered through the excitement between her legs. “...mmh...I b-bet my brother gets off on them...he’s a momma’s boy…”

Cadance’s eyes were lidded and the color of her face was all in her cheeks. She pumped Celestia again and whimpered at the sensation of the deepest portion of her aunt’s channel closing around her once more. The pinches turned her breaths into sharp slices through the air, and she grew close to Twilight, determined not to let her husband’s little sister get the best of her.

“...mmhmm, he loves them,” Cadance smirked, her lips inches from Twilight’s. “Th-the crystal palace is my domain, you know...nnh...my magic is strong there, nothing happens w-without my knowledge...including a wayward girl in her jammies rubbing her little love button outside her brother’s door while he fucks his wife…”

Both the claim and the accusation were bluffs, but Twilight went so red that the crystal princess knew she was onto something. Caught off-guard, Twilight surrendered to the tongue deep in her channel and rolled her eyes skyward, letting out a moan and bucking so fiercely that Celestia nearly gagged under her. The crown princess was a dutiful slut however, and she was quick to redouble her efforts, her snaking tongue instantly seeking out the spots inside her student’s pussy that Twilight liked best. Cadance bent to capture one of Twilight’s pert nipples with her lips, and found the student roughly encapsulating the other in her own hand.

Twilight, her eyes shut tight, writhed atop her mentor, slathering Celestia’s face in the nectar of her love. She felt sweet climax building up inside her - her engorged lips pulsed against the crown princess, but she resisted the final stage, biting back her cries in a display of insistence that gave Cadance pause. When the crystal princess inquired, a panting Twilight gritted out a reply:

“Hahh...w-with m-my Pet...hahh...hahh...I l-like it a c-certain way…”

Twilight thrust her arm abruptly towards the couch. Her hand began to glow, and the satchel next to the patiently observing Luna was encapsulated in the same light. It thrashed about, until from it emerged a bejeweled object that flew into Twilight’s grasp almost faster than Cadance could register. Twilight sat back, pulling herself from Celestia’s honey-stained face, and draped over her shoulders a necklace that was nearly equal to the one that adorned her sister-in-law.

Cadance watched as Twilight threw her head back and moaned. The student had become used to the enchantment the necklaces bore, and had a certain appreciation for adorning herself with one when her female neediness was at its peak - something about the transition made the resulting penis that sprouted from her loins feel thicker, twice as engorged, and three times as sensitive. When her girth was fully formed and eagerly twitching, Twilight went down on all fours and crawled over Celestia’s face, painting her cheeks with the pre-seed that the student’s prior arousal had already brought about. The crown princess found herself draped in Twilight’s raspberry locks on all sides, with the student’s voice oozing into her ears.

“Sh-show her, Pet,” Twilight muttered. “...sh-show her what a whore you are, show her how you like having me in more than just your pussy…”

Celestia writhed against the bonds that still held her wrists, but her purpose was not to escape. She let out a hard breath, bathing her student’s pulsing tip in it before allowing the tapered head to push past her lips and steal away her voice. Trained well by her sister-mistress, Celestia took the spire into her throat as quickly and deeply as Twilight wanted to go. Twilight then grasped both sides of Celestia’s head to hold her in place as she fucked her mouth like a toy.

“Mmmhmm…” Twilight cooed, “...o-only think about what I want...just accept it…”

Cadance paused once again to marvel at the image of her sister-in-law playing with her aunt, this time ramming the veins of a conjured but all too real phallus down Celestia’s throat whilst the latter bathed it in silky luxury and begged for more. Cadance pumped her aunt a few more times, but her attention was captured again - this time by Princess Luna.

Luna sat upon the guest couch like a queen enjoying the antics of her sensual fools. She was stroking her chin and had crossed her legs, but she seemed otherwise calm, and was the only one among them who still wore clothing. Her fingertips were glowing with magic, and though she passed the colors of aural power between them like water, Cadance saw no effect and could not identify the spell. Luna ignored Cadance’s eyes with haughty indifference, but favored her with words:

“Your in-law and your aunt are both my pets, as you can see. They lose themselves in ecstacy for my amusement, and in so doing become ever more vulnerable to my influence. The younger of them is quite right - my elder pet wants more than just a mere ride.” Luna’s fingers jumped, and the power arched up for an instant, “Not even two partners can satisfy her whorish lust alone.”

Cadance felt the warm body under her jump. With her organ still buried to the hilt inside Celestia, she had to glance behind herself to catch a glimpse of another toy, similar in girth to the one the crown princess performed upon earlier. This one was phantasmal - transparent and glowing with a ghostly light, it throbbed and twitched very much like the real thing as it slowly disappeared into Princess Celestia.

Celestia whimpered and shook as her third hole was filled up, but true to her service, she allowed the penis in her mouth to pass unabated all the way back into her throat to choke off her cries. This took some effort, and she earned a gentle massage over her breasts from her student.

“Mmmh…” Twilight cooed, “...good girl, good slut...show Miss Cadance how you much you love taking it all at once…”

Celestia’s legs were already widely spread, but she managed to lift and splay them even further in acceptance of the new toy that laid claim to her rump. Cadance repositioned herself until her hands enjoyed the plump softness of Celestia’s inner thighs. The crystal princess was off her game with all the new sights and sounds - particularly the pulses of electricity from her conjured penis, which rolled over her mind in cloudy waves of pure yet unfamiliar ecstacy. A glance from Twilight brought her back down.

“Fuck her,” Twilight whispered. “Don’t hold back. We’ll...nnh...fuck her together...you know you want to…”

Cadance’s eyes lidded, then closed. Undulating waves of yielding warmth rippled around her new member, sending messages to her brain she was never intended to receive. She dug her hands into the flesh that supported them, pulled back, and speared her aunt sharply, drawing from her a cry that vibrated around Twilight’s penis and elicited one from her as well. Want seeped back into Cadance’s brain - the want of command, of control, that she had yearned for even before the crystal empire had become hers. In that moment there was nothing but the desire to make her kin her own, and she began to ram herself anew into the pretty pussy beneath her, heedless of protection or concern for her partner.

Twilight let go of Celestia’s head, instead pinning the crown princess to the carpet with the force of her pistoning alone. The student slunk towards Cadance, and together they plowed out the parent figure that had for so long lorded over them, reducing Celestia to little more than a series of orifices to be claimed. Twilight’s pace became frenzied and her shoulders shook, but she removed one hand from the floor and used it to cup Cadance’s chin, turning their gazes together.

“...hahh…ahh...hahh...nng…” Twilight panted, “...c-cum w-with me...l-let’s both f-fill her up...annnghh…”

None of the three would be denied, for one was guided by a force of magic, and the other two by the explosions of their desire. Celestia swallowed her lovers by both ends and clenched in vain against the invader in her backside. Exposed to Luna in body and emotion, Cadance and Twilight cried out with passion and showed no shame looking one another in the eye, their necklaces jangling about their bouncing bosoms as they each made Celestia their own.

A welling inside the crystal princess spoke to her of what was to come, but her mind was reeling from the reversal - the desperation to inject herself into her partner and leave her mark. Twilight’s image was like swirling colors before her, and the cacophony of panting was a symphony of carnal glory that rang in Cadance’s ears and spurned her to mate. Command of herself fled, and at length she reared back and plunged herself to the instinctive deepest place she could manage, holding her lover there as she unloaded rope after rope of gooey thickness into Celestia’s unprotected depths.

Twilight could feel the orgasm of her in-law through the reactions of her pet, whose suckling became erratic. The rhythm changed quickly, leaving her unable to catch up until she too felt her moment on approach. While Cadance was still unloading into Celestia’s welcoming pussy, Twilight slammed herself in to equal depths, pausing as well, the now familiar pumping of her release gracing her mentor’s throat with her seed. As stiff as the rest of them, Twilight pulled Cadance’s face near and took her into a rough kiss, which they maintained as they each released themselves inside the same lover.

When it was all over, Twilight had the wherewithal to slip her erection slowly from her mentor’s throat, pulsing one last time as the bulge abated, before the three of them collapsed into a sticky mass upon the rug. Cadance and Twilight each chose a side of their elder to wrap around and a breast to absently fondle, for neither was quite finished with their elder’s luscious body. There they sought to catch their breath, as their mutual erections poked Celestia from either side.

Twilight grinned. “...heh...not done yet are you...”

The blush that crept up Cadance’s cheeks was unnoticeable in her glowing state, but her sheepish grin was. “It’s...heh...all so new. Can’t help it.”

Celestia nuzzled Cadance’s cheek, her voice just above a strained whisper. “...mmmh...I’ve wanted that for so long…”

Cadance perked. “Really?”

Twilight pushed a finger into Celestia’s mouth to give her something better to do with her lips, and spoke over her. “She wants this from all of us. And you want to give it to her. You proved that just now.”

Cadance glanced down at Celestia’s naked body. She ran a hand over her shapely form, unrestrained, and finally settled on a hip, which she gripped roughly. A grin spread upon her lips, and she bucked that same hip once more. “W-well I...maybe I did want to...make her mine.”

“Enough.”

Both suitors looked up. Above them loomed the wavy, starry countenance of Princess Luna. Standing next to them with her arms folded she cut a commanding figure, and both naked youths who were so many centuries her junior shrank. Luna arched a brow.

“You are not yet satisfied, Princess Cadance,” Luna said sternly.

“What?” Cadance glanced down at her hips, as if she had no control over them. “I...n-no no, this was great, I-I’m--”

Luna waved a hand, and magic began to glow from it. “Do not lie to me. In your current state, you are hardly capable of it.”

Luna’s magic took effect, and Cadance watched as her necklace drifted away. An instant later she was clumsily grinding her womanhood into Celestia’s hip - the sensation of her penis already a yearned-for memory. Luna wasted not a moment adorning herself with the bauble, and as a bulge appeared in her sweatpants she returned to the couch, sitting with mein of the fine lady she was.

“You lie,” the night princess repeated. “I can smell your heat from here, and it has not abated. You have enjoyed the trappings of masculine dominance. Now you will remember what you truly are, and as Twilight has already done, you will learn your place.”

Cadance sat up and quirked a brow of her own. “I thought you were planning to share your pet with me-” she stroked Celestia’s thigh, “-one ruler to another.

Luna chuckled. “Do not be coy, child princess. You are too used to ruling your own lands, and yet here you sit before me, low and naked, wracked by want.”

“I...can get up whenever I want.”

“You are staring at my gift to you,” Luna nodded at her crotch. “Your eyes have not left it since it appeared.”

“I-I…”

Cadance sought to summon her reserves, but an embrace caught her from behind. A second soon followed, until both the Sun and her student were snuggling into Cadance, one hand from each reaching around to toy with her tight tummy and pert breasts. A tongue began to grace her jugular, though she knew not from which lover it had come. Cadance shivered.

“I...I w-wasn’t staring…”

“You are above my pets,” Luna said dismissively, stroking her own leg in an inviting way. “But you will learn to be beneath me in our private circles. You may have your present, but you must come to me, on your knees, and unwrap it yourself.”

“I…”

Cadance blinked hard. She had no true desire to butt heads with Luna, but her instincts, as a crown princess of an empire in her own right, were to challenge any claim against her authority. She puffed up, but her swelling chest was captured by the hands that groped her, and each waning nipple was brought back to full mast while a pair of fingers skated slowly down her tummy to her unsatisfied womanhood.

“Give yourself to Mistress Luna,” Twilight whispered. “Let her mark you, the way she marks us all.”

Celestia drew close to Cadance’s other ear. She must have been untied at some point, for her fingers moved over Cadance’s spine in time with the Sun’s voice: “You know the pressures of total command as I do, my sweet niece. Let yourself have this, and you’ll know my heart better than ever before.”

Fingers found Cadance’s opening and dipped inside her. Luna commanded the room, forcing Cadance’s eye front by mere presence alone. The night princess sat calmly, a slight grin upon her lips, and waited. Only the bulge beneath her sweatpants piqued with excitement, and Cadance found her heart jumping along with it.

Twilight got an idea. She leaned close.

“You were right,” the student whispered to Cadance as Celestia’s tongue continued its work. “I was outside your room in the hall the last time I visited. And the time before that. And the time before that, too. Do you know why?” Twilight nibbled on Cadance’s ear. “Because I wanted to learn everything that you like.”

Cadance’s eyes went wide with surprise, but her thoughts were whited out by Twilight’s touch. The clever student began to trace Cadance’s pussy lips, pushing against the yielding opening with the flat of her knuckles rather than penetrating all the way with slender fingers.

“You like it when my brother teases you with his fat head,” Twilight whispered. “That first moment when it goes in, where it has to spread you further than when the shaft gets inside. You want to be spread open wide.”

“Did...he say…? That’s a secr--”

“Of course he didn’t tell me,” Twilight cooed. “I figured it out on my own. And you know? I told my mistress all about it. That and more. Mistress Luna knows you’re a ruler. She just wants to train you a bit. You should let her. She has so much to teach you...”

Cadance bit her lip, shut her eyes, and whimpered.

“Maybe your little sister-in-law should make you hers, hm?” Twilight said softly. “Maybe I won’t let you go home to my brother until you’ve had my cock in you, just the way he does it,” she giggled, “but then, maybe I wouldn’t be able to let you go, after that. We all know you haven’t really given yourself over to lust yet, not all the way. Maybe little sister’s dick is what you need.”

The crystal princess parted her knees farther. “...I...I did give in, I…”

“Nooooo you didn’t,” Twilight replied, every touch raising goosebumps on her victim now. “You’re still holding back. It’s like Luna said - you still smell like bitch in heat. You’re still getting wet, too. Because you haven’t used this yet--”

Twilight dug her knuckles roughly into Cadance. The elder in-law threw her head back and cried out.

“Do it,” Twilight urged. “Let her make you hers.”

Cadance’s supple flesh was alive with the tease of fingers and trailing hair from those who knelt behind her. She swallowed, forcing her eyes open, and in her vision there was nothing but the midnight package waiting to be opened. Already on her knees, her hands found the carpet, and the gift loomed larger in her vision until she was close enough to pick up the scent of the night princess. Marveling at her prize, Cadance nuzzled it with her cheek and moved to strip away its bonds with her hand, but Luna grunted, and Cadance felt both hands suddenly rooted to the floor by magic.

“Resist me,” Luna said curiously.

Cadance was confused by this, but she gave over to the command and lit her own magic in defiance, until she was able to reach an ensorcelled hand up to Luna’s crotch. It was a struggle, but not enough of one to make sense. Cadance was no slouch with her magic, but she was distracted by desire, and Luna had several centuries of experience on her - she ought to have been winning. A lack of comprehension alighted Cadance’s features, until a small, silver ring appeared floating in front of her vision.

“You know what it is,” Luna said simply, “my sister’s student found that out for me.”

Cadance knew very well what the little ring was intended to do - her husband had used a similar one on her many times. She slackened, expecting Luna to slide it onto her finger and win the contest that way, but the ring never moved.

“I have chosen not to overpower you by magic,” Luna explained. “Thus if you want any more of my attentions, you shall do that for me.”

Cadance felt that she could still resist - still continue her way. A tongue found the back of her neck again, and with a soft whine, she held out her hand and floated the ring onto her finger under her own power. Her energy winked out as the curse took hold, and Luna slowly guided her hands back to the floor, planting them firmly there.

“Good,” Luna observed. “Proceed.”

With her teeth, Cadance leaned forward and clumsily worked at the bottoms. Twilight and Celestia assisted, each one slipping the garment down past one of Luna’s hips, but not before Cadance put grunting frustration into her task and wilted under the gaze of those watching her. Luna had foregone panties entirely, and her gift to the crystal princess sprung forth thick and heavy, bapping Cadance right between the eyes.

Cadance was too horny to feign resistance. With a moan she rubbed her cheek up against the spire and then favored it with a long lick from base to tip, curving her tongue in the way her husband preferred. Unlike Twilight, Cadance had some prior experience with male anatomy. She paused only long enough to flood her lungs with a deep breath of Luna, before working up the shaft to the thin fold of skin that she knew would make even the night princess jump. Luna’s penis did indeed twitch, and Cadance used this small measure of control to envelop the tapered head slowly with her lips, causing it to disappear inside her.

Luna let out a satisfying, if not restrained grunt, and her hand came down upon Cadance’s head. Cadance came on strong, seeking to finish her younger aunt with the same gusto and pride that she usually did with Shining Armor, but Luna’s grip was like a glass ceiling that kept the lowly princess from rising to her own potential. Truncated in her performance, Cadance could only bob low, with little choice but to swallow the Moon to the hilt until gagging finally took her. At the sound Luna let Cadance up, but only just so.

Luna touched Cadance’s chin and forced it up, lancing the younger princess with her icy gaze. “Do you think I am your lover, little Cadance? That you can lord power over me in the form of giving pleasure in the way you want, force my climax, and thus choose when you will and will not be bred?” Cadance sought to reply, but Luna shoved back into her again to cut her off. “The fire in your belly pleases me. You are a fine ruler, but you have some lessons to take home with you.”

Twilight was grinding up against Cadance’s back. She reached under her in-law’s rump and began to finger the soft folds again from behind. “Ride her...let her take you completely, in the place only my brother takes you…”

An aura of magic encapsulated Cadance’s entire body. It ran along her form, like countless fingers of light, touching every place in ways no hands could. Cadance’s state of arousal amplified this, and she was thereafter lost in Luna’s deep eyes, drawn inexorably towards them until she willingly began to climb upon the elder’s lap.

“I...I…”

“Yes?” Luna said with frustrating calm, her lips mere inches away. “Speak your desire.”

“I...want you to--need you to take me…”

“To what?”

“T-to fuck me,” Cadance whined as Twilight’s fingers swirled around inside her. “P-please...please it’s driving me crazy…”

Luna grinned. Uppity to the end, Cadance’s hips were already seeking to lower themselves upon the stiff spire that would bring her bliss. Luna finally moved, dismissing Twilight’s fingers and placing both her hands on Cadance’s rump cheeks to hold her inches away from her goal. She then let the princess down slightly, until only Luna’s bulbous tip stretched the young lover that rode her.

“Nnngh--!”

“Cry out,” Luna whispered as she began to lower Cadance further. “Cry out with the passing of every plump vein as it drives you mad.”

Cadance shut her eyes tightly and bayed, her hands coming down with vice grips upon Luna’s shoulders. The invasion was slow but complete, Cadance parting to welcome and accommodate her new mistress. The Moon was slightly too long for her charge, and her tip mashed roughly against the entrance to Cadance’s womb just before the crystal princess could sit down all the way. This put Cadance on her knees, and unable to completely rest, she rose up again, only to slowly part and pierce herself anew.

Luna sighed with satisfaction. She wrapped her arms around her lover and pulled Cadance close, both allowing and forcing the younger to grind for pleasure. Luna took Cadance’s lips over and over in small pecks, always calm in contrast to the smaller princess’s needy groping.

“Ahh...hahh...hahh...nnghhhahh…”

“You weren’t finished.”

“I…oohh...I w-wasn’t finished…”

“You need this.”

“...nnghhh...ahhh...I-I...n-need this…”

“What do you need?”

Cadance was grinding harder, rolling her hips against the invader lovingly. “...I n-need Aunt L-Luna to...f-fuck my pussy…”

Luna stroked Cadance’s hair. “You will remember this when you lie with your husband.”

“O-ohh...oh yessnnnghh!”

Luna finally ended the game of words, and loosened her grip on Cadance to allow the girl to bounce freely. Bounce Cadance did, with an abandon that gave her desire away to the room and a chorus of dirty slaps of flesh against flesh. Her muscles caressed and adored her lover, until Luna too lost herself a bit, and began to lift the crystal princess with her own return thrusts.

The pair made love, their passion emanating in waves throughout the room that left their audience eager to sit upon the floor and play with themselves whilst voyeuring. Twilight had cast her necklace aside and was fingering her pussy, bringing herself to peak after peak with no restraint. Even Princess Celestia was lost in the scene - she dared not intrude upon any of her mistresses in their throes when they had not chosen to use her, so she watched her little sister claim another while riding again on the toy molded from Twilight’s calculated manhood, had she been born with one. Exhaustion made both spectators weak, and with no resistance they succumbed to chain orgasms that left them both withered in masses of flowing locks upon the floor.

Cadance cried out sharply with every climax her new Lady gave her, until Luna felt the familiar welling up of ejaculation inside her. With no thought for protection, she grabbed Cadance, shoved the girl down hard atop her, and began to release a torrent of semen into the depths of the crystal princess, sharing with her a bond that Cadance had only ever known with her own husband. In this way, Luna ensured that the memory of this moment would always be there in the back of Cadance’s mind.

Luna pumped and pumped until there was nothing left, and then melted into the couch, drawing atop her the lover who had soaked it all up. Flustered now in her own right, the night princess spoke through heaving breaths as she stroked Cadance’s hair and mashed the younger’s face into the soft valley of her breasts.

“...hahh...hahh...you have...excellent taste, Twilight Sparkle…”

Cadance looked up. “What?”

Luna ignored the question and took Cadance in a gentle, affectionate kiss. The gesture seemed to sap what little strength the crystal princess had remaining, and her head plopped again down on Luna’s springy chest. Luna stroked Cadance’s pastel hair and spoke.

“Your aunt has wanted this for some time Cadance, in her fantasies. But she would not have approached you on her own. What happened with you today in the throne room was also unplanned, but had it not occurred, your sister-in-law would have brought it about anyway.”

Twilight was stark naked on the floor, sweaty and sitting with her legs lewdly parted and her back up against a chair leg. She was staring off into space with a dreamy look in her eyes, but chuckling lightly. “Mmmhmm...I knew you’d be into it, I just knew it…”

Cadance blushed, as though she had only just then become aware that she was naked with a penis inside her, on display to her aunt and sister-in-law. She cleared her throat. “I...well you know, Aunt Celestia--”

“I know, yes,” Luna said simply, not allowing Cadance to finish the thought. She toyed with the younger ruler’s hair, winding it about her fingers, and pumped Cadance once with her summoned member just to make her jump again. “But you are not like my other pets. You can be tamed, but your desires are...closer to my own.”

Cadance sat up, but instead of dismounting, she twisted her body enough to favor Celestia with a glance. The sun princess, used the most of any of them throughout the day, was hovering just around the level of consciousness. She had collapsed upon the floor and was sprawled out in an undignified way, the Twilight-toy still inside her and a silly grin on her face. She was so much more relaxed than Cadance could ever remember seeing her, her bosom rising and falling with breathing that had reached the rhythm of sleep.

“You look upon her as a plaything,” Luna ventured. “Not a slave of course, but as a beloved pet-creature that until now, you have had no means by which to collar. She is mine of course, but there are certain, shall we say…concessions available to you, Princess Cadance.”

With that Luna rose, breaking contact with her charge and depositing Cadance on the couch. The night kicked off her pants and without bothering to remove her necklace, walked towards the balcony to summon the moon for the evening.

This was Twilight’s cue. Leaving Celestia to set like the sun, the student rose and stepped lightly across the room, her nakedness resplendent in the pale light. She retrieved the satchel from where it had fallen on the floor, drew from it a third onyx necklace, and sat next to Cadance, draping the bauble over her in-law’s lap.

Cadance eyed it. “That’s...my personal symbol.”

Twilight nodded eagerly, but at Cadance’s silence, her expression fell. “I...I thought you might like it so I went ahead and just made one for you...I can recycle it if you’d rather…”

Cadance had her eye on the necklace. She fingered it, stroking the jet with her fingertips. “...always the overachieving student, aren’t you.”

Twilight wasn’t sure what to make of this. She frowned, but Cadance reached over and unabashedly took the student’s cheek in a caress, wrapping her lips into Twilight’s with the gentleness of afterglow. She parted Twilight’s lips and mingled tongues with the girl, until Twilight’s shoulders weakened.

“Mmhmm,” Cadance grinned as she pulled away. “Your brother takes kisses the same way.” thoughtfully Cadance sat back, her attention on the necklace. “This will be fun for when I come to visit, but...I do love my Shiny.”

Luna, finished with her work, stood facing the city. The spell was still upon them for a few more hours, and thus the second princess of Equestria felt no concern, even going so far as to shed her top and stretch her body, sighing as her form was bathed in cool breeze. “We considered that eventuality too, Princess Cadance. I believe it is the last item in the bag.”

Before Cadance could get at the satchel, Twilight produced from it a simple scroll, marked with Luna’s signet set in wax. She handed it over, and without hesitation Cadance broke the seal. Her eyes passed over the text, and her brow knitted.

“Is this…?”

Luna swaggered back into the room, brushing her hands through her hair as though she were bathing. “That it is. Your husband will make an attractive and shapely young lady during your private time with him. Why wait to use your newly acquired artifact?”

Cadance stared at the paper. Then her lips curled into a conniving smile.

“Oh...you have no idea.”

Twilight lounged comfortably, her hands behind her head. “He’ll like it. And you’ll like getting him used to it.”

Luna was standing over Celestia. She seemed in thought, as if planning to move her sister, but Cadance spoke up.

“She’s fine on the floor, isn’t she? It’s a good spot for a pet.”

Luna smiled. “Well said, Princess Cadance.”

2 - Learned Behavior

“See to it.”

It was a harsh command, and Princess Cadance felt a pang of remorse for barking it so sharply to a guard who hadn’t done anything wrong. The young man, kitted out well in his crystal armor, hopped to the task of closing the large double doors that sequestered the royal apartments from the rest of the palace. He had apparently thought the order as harsh as his princess had, for he rushed to obey without querying another guard for assistance, thus putting the onus of securing the sizable portal entirely upon himself. His armor clanked, the sound like deep wind chimes, and paused to regard his mistress just before the end of the job, as if asking what side of the doors he should stand guard upon. Cadance merely eyed him, and the young man recalled the obvious answer as he scampered to the outside.

Within, bathed in the glow of late afternoon from a multitude of high windows, was the royal apartment complex. It was a good deal larger than just the residence of the prince and princess, with many doors on either end of one wide hallway leading to private chambers intended for special guests or honored retainers of the crown. It was well lit on purpose to show off the glow of glittering stone that the Crystal Empire was so well known for, with ample sconces for perching torches at night, and wall-mounted mirrors that caught the light in clever ways. Portraits of rulers from ages past graced the walls, with only one spot barren - that of the king who had ruled just prior to Princess Cadance, locked away in the most heinous memories of the populace.

Cadance banished the reverie and moved down the empty hall on light steps, her gilded slippers clacking out a rhythm on the solid floor. She was dressed in flowing satin robes of state - prismatic on purpose, to make the Lady of the land shine like the empire over which she ruled. The garment bore many marks of office and her tiara topped off the ensemble of the highest authority, but Cadance wanted nothing more than to shed it. It was beautiful, but it was heavy, and the careful moves she had made to secure for herself and her husband an entire afternoon to themselves had been going on for more than a week.

As she walked, Cadance thought on her aunt Celestia’s birthday celebration in Canterlot, now a memory by nearly a month. Both of the ‘gifts’ from her kin had been stowed away the moment the princess retook her station, and Cadance had barely the time to so much as think about them since her return trip. ‘Barely’ being the opportune word, for though she and her significant other had much to do, they weren’t so starved for freedom that a little discussion couldn’t have happened first...and a little preparation.

Cadance placed her hand on her door, then her ear to it. Satisfied that the buzzing noise was still extant, she pushed open the portal that her retainers were under strict orders not to disturb and let herself in.

Therein lay the royal chambers as they may have looked on any other day - clean and pristine, with ornate furniture from all over the empire and fresh flowers on the sitting room table. The room was glowing with light from drawn curtains, just the way Cadance liked it, but the main area was not her goal. Favoring the images of family and the cozy throw pillows with a glance, she passed into the hallway and back towards the bedroom, her ear upon the constant sound that would have been easy for anybody who did not know it was there to miss. The picture of a woman certain of her own absolute authority, she pushed open the final door with no hesitation and left it ajar, grinning as the mingled shadows and light cast her in relief.

“I’m sorry honey,” Cadance oozed, “I know I said I was only going to be an hour, but it took two, didn’t it? Don’t get up, okay?”

“...mmmhh...hhhgnannh...ahh…”

Cadance smiled. There upon the bed lay her husband, the prince of the crystal empire, in all “his” pale glory. He was bereft of but one feature - his rippling musculature, which magic had replaced with all the lavish curves and springy grace of womanhood. The spell had promised a complete, if not temporary, reversal of gender, and thus ‘her’ body appeared exactly how it would have developed had he never been introduced to the Y chromosome. Shining Armor was half a head shorter than her wife, with a subtleness to her body that made her even mousier than her sister, save for the bosom. In that are she was well-endowed indeed, so much so that Cadance suspected Twilight had added just a tiny bit of embellishment when crafting the spell.

Cadance sat on the edge of the bed quite casually, and reached out to help herself to the hard nipple that capped her husband’s right breast. Shining Armor jumped satisfactorily, though she could only go so far, for she was tied spread-eagle on her back to all four bed posts by hempen rope that her wife had chosen on purpose - weak enough for her to break as her original masculine self, but too much for the female she had become.

“Oh my,” Cadance observed. “I really had no idea you would be so...busty, dear. I bet it feels funny, jiggling like that all over the place.”

Shining Armor nodded weakly and moaned again against the gag in her mouth, her eyes rolling to the ceiling whenever the buzzing toy that had command over her pussy gifted her with another unfamiliar, clumsy climax.

“How many have you had now, I wonder? A dozen? More?”

“...nngh...mmmh…”

“It’s not like anything you’ve ever experienced before, cumming over and over again, is it,” Cadance said as she ran her hand down to Shining’s tummy. “How does it feel, Shining Armor?”

Shining grunted deliciously, but for her trouble she received a slap on the chest. She winced, and with her brows turned up, asked with her eyes what she had done.

Cadance lifted a brow. “That’s the reaction I expect, but you’re still not trained properly. We talked about this, there is no Shining Armor right now, is there.”

Shining shook her head. She looked positively pathetic with her long, flowing cerulean locks matted about her face and neck, but Cadance looked past the image and continued on.

“When I told you about my experiences, do you remember what you said? You said you were envious of Princess Celestia, that she has someone in her life to take all the stress of command away. And you do have such a hard job running the military and being a prince at the same time. Don’t you.”

“...uh-huh…”

“You would never let anybody know how stressful things are for you except for me, and wouldn’t you know it? I need to blow off my stress alot too. Strangely enough, I just happen to have the opposite way of showing it--” Cadance laced her fingers together, “isn’t it great how well we mesh?”

Shining Armor whined in a pitch higher than even Cadance could manage and struggled uselessly against bonds that weren’t all that oppressive. Cadance reached out to the toy, and jammed it in a little further.

“All that love juice is making this slip out, and we can’t have that,” she explained. “But there is no Shining Armor right now. Your name is the one I gave you: Gleaming Shield, Twilight’s adorable, but meek little sister. She’s not a prince, and she’s not a guard captain. Of course, she’s not a man either, so she’s no husband.”

Gleaming Shield moaned.

“She’s my pet. My adorable little pet.”

Cadance left her new pet in bondage and swept over to a chair by the window. Making quite a show of it, she slowly stripped off her robes, layer by later, and draped them over the chair until the piece of furniture looked like it was in storage with a tarp over it. She then turned her profile to the window and closed her eyes, gracefully removing a few ties that kept her hair up whilst presenting to her pet all the sultry softness of her naked body, for she had not bothered to dress beneath her garb of office. One by one she dropped colorful ribbons to the floor, and then fluffed out out her candy-coated hair to grace her form all the way down to the small of her back. She turned away, smiling smugly, and glanced at Gleaming over her shoulder.

“Did you peek?”

Gleaming Shield’s eyes went wide. Somehow she managed to blush deeper, and muttered an unintelligible negative into her gag.

Cadance turned again, just to watch the eyes of the obviously lying young lady follow her hips some more. Only one accessory still remained on Cadance’s body - the necklace of onyx and jet, gifted to her by her Canterlot kin. She reached down and brushed her fingers over her thick penis head, jerking her muscles just to make it bounce once.

“That’s right,” she confirmed, “I had it on the entire time. Even in the throne room.”

“Mmhgnh…?”

“If anybody noticed, they wouldn’t dare question a princess, now would they?” Cadance replied. “Clearly their eyes were playing tricks on them. There’s a lot of light in that room, after all.”

Gleaming wilted, and finally nodded her agreement. Her eyes remained on the image of her wife, who seemed to have taken from her something that once made her feel confident in the bedroom. In an unfamiliar body and wracked by two hours of orgasms, Gleaming Shield was left with all the experience of a wedding-night virgin.

Cadance was at the bedside again. She slipped over her pet’s lithe form and straddled Gleaming’s waist, forcing her to go cross-eyed trying to keep the princess’s head in focus as it pointed at her.

“That’s right, you’ve never actually had one of these before, have you?”

“...uh-uh…”

“Because, as I recall you saying, you ‘never really thought about it’ before.” She leaned forward, painting the gag with her pre-seed, for seeing her husband in this form had brought forth quick arousal. “Now things in your head are different though. Now you’re thinking about being filled, not just doing the filling. I know, because that’s how it was for me.”

“....mmh.”

“Are you thinking about it, little Gleaming Shield?”

“...uh-huh.”

“Do you want your mistress’s penis to take you to levels of bliss you could never find with one of your own?”

Gleaming Shield nodded.

Cadance summoned her magic, turning the toy inside her pet down to an agonizing slowness. She waited until she could tell Gleaming was gripping wantonly at it, and without bothering to use her hands, took the gag in the aura of a spell and slipped it away. The moment it fell free Gleaming began to pant deeply. Cadance let her charge get in a few deep breaths, and then reached down to helplessly pinch Gleaming’s nostrils closed.

“Come on…” Cadance cooed as she touched her tip to Gleaming’s lips. “Take a breath and open up for me…”

Without knowing ahead of time that her nose would be inadvertently closed, Gleaming Shield had little air in her - and no recourse but to breathe. She opened wide, and though Cadance mercifully let her nose go, she didn’t hesitate for a moment to slide her girth into her pet’s mouth. She moved with deliberate slowness, allowing Gleaming to get used to the sensation and avoid gagging, until she was just beyond halfway inserted. There she stuck, and ran her fingers through Gleaming’s pleasantly thick, flowing hair.

“That’s about all a newbie like you can handle,” Cadance remarked as she pumped her pet’s mouth once. “Imagine what it’s going to be like when you can swallow me all the way. It will happen eventually, because you’re going to get lots of training in how to be a good girl, and a dutiful private pet. Maybe your big sister can even help us out a little, sometime.”

Gleaming devoured the words as surely as she accepted her new gag, and began to suckle. The movements were as clumsy as Cadance expected them to be, but her pet had some control, and the tight lips that surrounded her were pleasing. The crystal princess reached back to stroke Gleaming’s tummy again.

“We’ve talked about having a little one, but wouldn’t it be better if it were the princess who got her little pet pregnant?”

“...mmmmh…”

“You’d look just adorable with a swollen tummy. Maybe I’ll even share you with the guards sometime so you can really feel like the little whore you are. After I breed you myself, of course.”

“...ooh…”

Cadance began to move, and as she expected, her words encouraged her mate to work harder. Gleaming’s tongue was dancing in random patterns around each vein that invaded her, as the young lady did her best to suppress her gag reflex and beg for more. Gleaming gave her what she wanted, piercing just a little bit more with every thrust, though she kept the rolling of her hips gentle.

“Mmh...you have no idea how hot it is, seeing you taking me like that…” Gleaming whispered, “and how you know, that I know, what this feels like for you…”

Gleaming coughed once, but when Cadance tried to pull away, the pet whined and formed a tight seal around the back of the crystal princess’s flare. The move wasn’t planned, but the vacuum-tightness of the seal was like a live wire throbbing in Cadance’s mind, lighting up everything it touched. Without thinking about it she planted one hand on Gleaming’s head, forced her back into the pillow, and bent further over her, thrusting in and out to the new sensation.

“Nnnh...hahh...y-you lied to me...y-you’ve been getting pointers somewhere…” Cadance shuddered, her neediness piquing, “...j-just don’t forget that with magic, I...c-can go more than once…”

Gleaming prepared herself as best she could for her first ever injection of warm semen, but as Cadance’s peak hit her, she yanked herself out of her lover’s mouth and bathed Gleaming’s face in bursts of sticky wetness, forcing the girl’s eyes closed as she painted her with seed.

“Ahh….ahhh! Y-yes,” Cadance instructed, “...t-turn your cheeks to it...e-each one...g-get it all over your face...o-open up…”

Gleaming did everything she was told, allowing hot ejaculate to seep into her skin on both sides. When she opened her mouth again. Cadance merely poised herself there and unloaded another single blast - just enough to coat her pet’s tongue and give her something to swallow.

Cadance was in bliss. She pushed out her chest and fondled it, arching her back with orgasm, and watched her pet accept her gift over the valley of her own breasts. “...ah...hahh...hahh...g-good girl...s-swallow…”

Gleaming did, but she hadn’t long to experience the curious texture of semen. Overwhelmed by the desire to dominate, Cadance ensorcelled all four ropes at the bedposts and yanked them free with her magic. She then grabbed the smaller girl around the waist, pulled her up to her knees, and roughly took her lips, mashing her into a deep kiss until Gleaming was moaning against it. Satisfied, Cadance dropped the weakened pet and flipped her over, yanking up her rump and leaving Gleaming with her cheek mooshed into the pillow the back of her head had been on moments ago.

Cadance grabbed Gleaming’s rump and held it firm, tossing the toy aside with another burst of a spell. “With this new body of yours, I’m stronger than you now,” she whispered, “I can take you however I want…”

Gleaming’s lips were free, but she emitted only the yips and whines of an animal in heat. Womanly arousal had conquered her, and she pointed her rump up against her lover’s hands, as if trying to will the throbbing penis that was already alighting her to pierce inside with abandon.

Cadance didn’t make her wait. With a rough thrust and no thought for finesse, the crystal princess laid claim to her mate, spreading her walls with an invasion that was greater even than any she had ever received from him in return. They were a couple out of sorts, neither used to being the other, and so their lovemaking was even more innocent than it had been the first time they had been together. They cried out, their calls echoing through the walls of the royal apartments on deaf ears, as Cadance reveled in the claiming and her lover in the sweetness of surrender.

The crystal princess’s hand came down hard on her pet’s backside over and over again, reddening the flesh. Gleaming Shield pushed back against it, accepting the blows with dutiful neediness. Each hard smack pushed her over the edge, until she was lost in a chain of climaxes that were unquantifiable in her mind. Atop her, Princess Cadance rammed herself home with thoughts only for her own release. When she knew the time had come, she grabbed both of Gleaming’s wrists and yanked, pulling the smaller girl up as she slammed her penis home and held it in her pet’s deepest place. An explosion not unlike volcanic eruption burst through Cadance’s mind and down her nerves, until her hot love coated the insides of her fertile partner in burst after powerful burst.

When nature’s demands had finally been satisfied, Cadance tossed Gleaming back onto the bed and flopped atop her, pinning the new girl onto the mattress. They panted, each gasping for air, until the former was again able to form words.

“...mmmh...wh-what do you have to do for the rest of the day…?”

Gleaming’s exhausted voice bore a tinge of mirth, “I thought…th-thought I’d r-review the troops…like this…heh...”

Cadance took a deep whiff of Gleaming’s hair, filling her lungs with her husband’s familiar, and yet strangely new sweet scent. “Someday you will...you’ll do it exactly like this…”

“...yeah…”

“For now though, you’re not going anywhere. Mistress is bigger than you, and you’re stuck here until I feel like moving.” Cadance settled in, nuzzling her lover’s back. “And that’s not going to be for awhile.”

“...y-yes mistress…”

“You’re learning,” Cadance sang coyly. “Good girl.”

The day went on, and the Crystal Empire persisted despite the temporary absence of its ruling family.
