Dr. Mary Parvotti leaned back in her chair and stretched her arms above her head, shivering with relief. Wearing nothing but a lacy white bra and panties, she yawned lustily in the meager glow of the desktop lamp as she waited for the encryption to finish. After a few minutes, she heard the whoosh of her emailed summit report winging its way to Lt. Kurosawa, written with the doctor’s usual level of fine detail. For a moment, Mary wondered if the extra effort was worth it, but she quickly put the unbecoming idea out of her mind. 
Anything worth doing was worth doing correctly, even if nobody else noticed. It was a moral lesson that might have come right out of Sun Princess Celestia’s regal mouth.
Mary chuckled at the thought. Honestly, Celestia didn’t really go in for such trite truisms, but the pure, Mother Goose-like image the Princess intentionally cultivated was hard to shake. Even for someone who knew the truth.
Mary glanced over at the wide bed next to her desk, piled high with cream-colored blankets and pillows. Just beyond, the large windows of the suite opened into evening darkness, and she could just make out the breakers crashing against the sharp rocks of the island’s western edge.
The Princess had only been gone a day, and Mary had already become so anxious. She knew she had it bad, but realizing just how much she missed the alicorn was frightening. There were always matters to take care of in Canterlot, of course, and an increasingly volatile diplomatic situation on Earth provided the perfect rationale to spend some time at home. Mary knew these things intellectually, but she still had a hole in her chest every second Celestia was away.
Home. She turned the word over in her mind. Where did that place exist, for either of them? Mary thought she felt the hole grow a little wider as she considered the question.
She was glad they didn’t have to skulk around anymore, at least. Mary and Celestia’s relationship had become an open secret among the members of the hastily-formed global organization tasked with handling all aspects of the Princess’ visit. Nobody ever said a word when Mary went up to Celestia’s room in the evenings, and they’d never been called to the carpet for their…antics. Aside from a week ago, of course.
As the memory of last weekend’s pleasures returned, Mary put a hand to her crotch and squeezed her legs together, causing a tingle to run from her cunt through her spine, and straight into her lizard brain. Julie had certainly been a delectable little piece, hadn’t she? Such a tight, fuckable little hardbody, and so open, so…pliable. Mary had often considered getting in touch with her over the past few days, but there simply hadn’t been time. That, and she didn’t know if she could justify Julie having access to Celestia’s place. There was only so much she could explain away.
Mary’s gaze went back to Lt. Kurosawa’s name on the outgoing email. The doctor had been ready for the worst after their tryst in the sands, especially after being recorded, but Julie’s mother had been strangely silent about the whole thing. Either she was still in the dark, or she didn’t care, and knowing the Lieutenant’s personality, Mary doubted it was the latter. That meant that someone was covering for them. Such knowledge might have been a source of relief if it didn’t bring up more questions.
Mary closed the laptop and looked at the time on her mobile: 7:00. It wouldn’t be too much longer.
They both certainly needed the relief. The day before yesterday had been more stressful than most, with the pro-magic bloc of countries being particularly demanding during the weekly global summit, and Princess Celestia found herself playing the bad bitch in order to correct a lot of unworkable assumptions. Mary sighed ruefully as she remembered some of the requests from state leaders they’d had to shoot down. No, we can’t set up teleportation booths on every block. Yes, there are flight spells, but you can’t have them yet because you’re guaranteed to kill yourselves. No, we can’t conjure enough food to solve world hunger. Yes, we can teach you how to enchant your fields to increase your yields by 100%, and before you ask, no, we can’t speed up the process.
Their intentions were good, at least, and it never hurt to ask. Magic didn’t exactly follow Earth rules, after all. Celestia worked hard to be accommodating in suggesting alternate solutions, but there were rumblings that a few countries were not taking rejection well. That had been the main thrust of Mary’s report, and the reason it took up so much of her mental energy to finish. She didn’t want to think about Celestia being caught up in some sort of trans-dimensional conflict, but taking those possibilities into consideration was part of her job. Unfortunately.
The mobile buzzed on the desk. “Speak of the devil, and you shall see her horn,” Mary muttered with a grin as she saw the simple message: “60.”
The doctor slipped a finger under the waistband of her panties, trying to keep herself on edge without going over. She bit her lip as she began the countdown in her head. The Princess had used their personal code, meaning that she would arrive in sixty seconds. 
Her timing was always exact, down to the instant. And at the end of those sixty seconds…well. The Sun Princess only used that code when she was feeling particularly nasty. Anything could happen.
Thirty seconds to go. Mary put her teasing finger in her mouth, savoring her own creamy flavor, then she rose on already unsteady legs and went over to a spot facing the doorway of the suite, where she stood with hands clasped, like a nun at prayer. She wanted her almost nude body to be the first thing Celestia saw upon her return. More than that, she didn’t want to wait an instant longer than necessary for whatever was in store.
Ten seconds. Mary could feel the hot juices sluicing down the insides of her thighs. She strained to her the alicorn’s footsteps coming down the hall, though she knew this was futile. Celestia could make herself as silent as a prowling cat, or she could cause her hooves to crack like thunder against any surface. In this situation, she wouldn’t reveal her presence until the very last moment.
Zero seconds.
The suite’s lock clicked as it turned green, and the door swung open. At first Mary only saw Celestia’s broad barrel chest and stout legs on the other side of the threshold, then the Princess ducked through the entryway, squeezing her draft-horse-sized body into the room like a childhood monster before coming up to her full height again. The dramatic effect made her seem even more mysterious and imposing than normal, if that were possible.
Mary’s breath hitched as she saw the thrumming piece of meat hanging between Celestia’s legs, slapping impatiently against her white-furred stomach. Three feet long and thick enough to embrace with her whole body, the black and pink cock was already drooling slime from the wide slit, and the basketball-sized nuts beneath pulsed with strain. Did she even bother to hide it on the way up, or did she let it swing free in her haste, not caring if anyone saw? The thought was electric.
Mary noticed all of these things in the moments it took for Celestia to reach her from the entryway. The alicorn had not stopped moving forward since she’d entered the suite.
“Princess. Welco-“
A gold-shod hoof on her head interrupted Mary’s greeting as she was brusquely shoved backwards onto her well-cushioned ass. She felt her head being lifted and brought forward, and her entire field of vision was abruptly taken over by the sight and smell of the Princess’ rampant prick. The enormous flare pulsed as it uncontrollably spat lines of fragrant pre all over Mary’s gasping face, and the barnyard aroma of Celestia’s excitement was a bomb in the doctor’s brain, almost causing her to orgasm on the spot.
The tip of Celestia’s fat cock became a battering ram as it mashed against Mary’s lips, pushing and shoving until Mary was forced to open her mouth and take what she was given. Her whole world was nothing but the underside of Celestia’s pure white belly, the spongy hardness of the log working its way down her neck, and the white-hot saltiness of its emissions. She began to shake like an addict finally getting a taste. God, she needed this.
Celestia began to desperately squeeze as much Princess cock as she could into the warm, wet holster beneath her, pumping hard for each inch. Every sharp thrust slid Mary backward on the carpet, and Celestia followed, until the back of Mary’s head slammed against the far wall of the suite. The Princess reared up and leaned her forelegs against the wall to brace herself, then the only sounds were of feral grunting and sloppy wetness as she began to face-fuck in earnest, working and clapping her sun-emblazoned ass over and over as she fought to hilt her entire fucktool, from the crown to the balls, into Mary’s gullet.
The doctor accepted it all, feeling Celestia’s magic stretch her insides as she was molded into a perfect receptacle for the Princess’ lust. Mary touched her stomach with both hands as she endured the assault, feeling the clear outline of that perfect cock fully housed in her chest, and she instantly came, moaning around the invader like a beast and spraying her silkiness all over them both while her legs shook with pleasure.
Feeling and hearing Mary’s orgasm seemed to stoke Celestia’s lust to a whole new level of heat. Her grunts and snorts became louder and rougher, and the steady clap, clap, clap of her giant balls against the doctor’s shaking tits doubled in cadence. Mary grasped Celestia’s hind legs in each hand, stroking the soft fur in encouragement, touching the backs of her knees in particular. It was a strangely intimate gesture compared to the rough action the Princess was giving her, but Mary was familiar with Celestia’s more sensitive areas. She knew how to finish her lover off quickly, and the results spoke for themselves.
With a loud grunt of release, Celestia buried her cock in Mary and held herself there, shaking as her giant balls lurched and delivered their payload. Spurts of thick come blasted into Mary’s depths, making her belly swell to pleasing roundness until the overflow splattered from around the seal of Mary’s lips, covering her chest with a tacky white mess. As usual, Celestia’s orgasm took a good few seconds, and when she’d finally drained her nuts much of Mary’s body, along with the carpet beneath them, was saturated in royal cream.
Celestia sighed in pleasure as she slowly dragged her thick cock from Mary’s stretched throat. After the wide flare was extracted from between her lips, Mary coughed up more come, further adding to the puddle between her thick thighs. Celestia backed off the wall, and for the first time that night, Mary saw the Sun Princess’ face.
A drop of saliva splashed onto Mary’s already well-soaked cheek, dripping from Celestia’s lolling tongue, long and obscene. The alicorn was panting hard from her slack mouth, and her exhalation felt like the heat of a forge on Mary’s skin. 
Celestia’s normally piercing eyes were dilated and unfocused, and Mary imagined that the only distinction she was making between objects in her view was whether or not they had a snug hole to sink her cock into. The whole effect of Celestia’s wild expression was disturbingly erotic on someone so majestic, and when she looked down at Mary with hunger the doctor trembled lustily. She had difficulty finding her voice, especially given the state of her abused throat.
“We…welcome ho-“
Mary’s hips jerked forward as Celestia took her meaty legs in her hooves, raising them until she’d bent the doctor in half in an impressive display of either Mary’s flexibility or her magically affected body. The lacy, soaked-through panties clung to her messy cunt, and they did nothing to conceal the pulsing ring between her big ass cheeks. 
Celestia spread Mary’s thighs wide, opening her up completely, and she peered down at her prize like a starving woman might covet a rack of lamb. Her thick cock had not softened in the least, and she barely had enough presence of mind to tear off Mary’s useless underwear before pressing the flare of her tool against the engorged lips of the doctor’s drooling gash.
Mary gasped, then she wailed as the monstrous length slowly worked its way into her, stretching her out methodically in a completely unnatural, completely magical way. Celestia snorted and grunted, bearing down with her majestic haunches, and they both watched the outline of the cock in Mary’s stomach move higher and higher until it reached that ultimate barrier.
Celestia only growled as she reared back and slammed home, then again, impossibly forcing her way through Mary’s cervix with single-minded determination as her partner screamed, not in pain, but in ecstasy. The magical breaking down of her core until she accepted Celestia’s pride within herself was a moment she’d come to relish, and she spurred the Princess on through clenched teeth.
“You miss this pussy? Huh? Got the pick of all the trim in Canterlot, but you can’t even get off with your own species, can you? I bet they whisper about it. Bet they call you a human-fucker behind your back. But that’s okay. You’ll never find a pony pussy this tight and wet. Fuck that cunt, fuck it, break me open. Take what’s yours, Princess. It’s your royal right. Fuck me!”
One more sharp thrust, and the weakened ring of muscle within Mary finally gave way to the inevitable. The Princess hilted herself fully inside the warmth of Mary’s channel, causing them both to moan and grunt like animals, but Celestia cut off Mary’s noises of pleasure with her own seeking tongue, kissing her with a terrible fierceness.
Celestia continued to pound away with maniacal intensity, extracting herself almost fully before slamming home over and over into Mary’s depths. She groaned with the need for release as her balls slapped a rhythm against the doctor’s upturned ass, and Mary could feel the throbbing heat of that impaling slab of meat as the Princess drove toward her conclusion.
A roar rattled the windows as Celestia sank into Mary’s welcoming wetness one final time, and her fat nuts sent a second volley of thick come into the doctor’s sucking womb. In moments, torrents of spunk flowed from around the pulsing cock, greatly expanding the puddle beneath them. The moans of contentment from the Princess combined with her prodigious load, not a whit lesser the second time around, caused Mary to scream her own release and add her creamy juices to their joined spendings.
Celestia pulled back as she finished, drawing herself out of the doctor’s still contracting fuckslot. The last thing Mary remembered as she lost consciousness was the geyser of come that erupted from her wide-open cunt as Celestia freed herself, covering them both with the Princess’ sweet love.



The sunlight of early morning gently prodded Mary into semi-wakefulness. 
She sensed that she was in bed, and she lay there with eyes closed a while longer, enjoying the sensation of being surrounded by softness and warmth. Although she wanted nothing better than to drift back into slumber, Mary knew her responsibilities wouldn’t wait. She was nothing if not diligent when it came to her work, and not even a torrid fuck strong enough to send her into Dreamland would change that.
Mary struggled to rise, finding her movements restricted. She cracked her eyes open and gingerly felt around with her hands, trying to figure out what was happening. The gradual understanding of her new position made her smile, though she was still too tired to fully laugh.
The doctor was on her side among the oversized bed’s pristine white covers and pillows. Celestia was behind her, spooned up against her plush butt, with the Princess’ forelimbs entwined with Mary’s arms. Celestia’s gentle body heat and steady breathing were a natural relaxant, enveloping Mary in a cocoon of safety and contentment.
Directly in front of her was the reason for Mary’s current situation. Celestia’s massive cock was laid against her bare chest, thrust between her legs from behind. The royal breeder was a little soft yet still rigid enough to be intimidating, and it smelled of semen and her own fragrant juices. Mary could feel the fat prick throbbing against her unprotected cunt, while Celestia’s prodigious balls rubbed against the backs of her thighs. It was almost as if Mary herself possessed a Princess cock, and she gently embraced the slab of meat with both arms, indulging in the brief fantasy. 
The fat cock moved in Mary’s grasp, sliding up and down on its own, ever so slowly yet insistently. It ground itself against her erect clit, coaxing more slippery fluid from her overworked lower lips, and Mary hummed as she enjoyed the sensation. 
“You should sleep a little longer.”
There was that mellifluous voice. Mary looked up to see Celestia craning her head downward, examining her with her usual preternatural composure. No sign of last night’s unrelenting lust showed in the alicorn’s diamond-bright eyes now, only hints of warm, comforting amusement.
Mary reached a hand up to stroke Celestia’s white-furred neck. “Princess.” Her smile widened. “Welcome home.” 
Celestia pressed her forehead against Mary’s as they shared a tired chuckle.
The Princess nuzzled Mary’s cheek. “You certainly made me feel welcome, little pony. Now, I insist that you relax. The world will keep spinning if you stay in bed for a while.”
Mary let out a soul-deep sigh. “Temptress. You know I can’t do that.  We’ve got your Canterlot debriefing at 8.” Mary glanced around. “Clock. Where’s a clock?”
”My goodness, I must have wrecked that little pussy,” Celestia said with a deadpan expression. “There’s one right in front of you. Did I fuck you into blindness?”
Mary slapped the flat tip of Celestia’s cock in playful annoyance. It was like hitting a side of beef. “If the product of this whole cross-cultural experiment is jokes like that, we may as well pack it up. Look, I’m serious. What time is it? Where’s my phone?”
Celestia stroked Mary’s short brown hair with a hoof. “It’s 7:00, and I’ve moved our meeting to this afternoon. It’s already been cleared with Lt. Kurosawa. You now have the morning off, so stop fidgeting. Everything will be fine.”
Mary obeyed, gratefully resting her head upon plush white pillows. “How’d you swing that? Kurosawa is a meeting fiend, and I know she wants to go over the pro-magic situation as soon as she can pin me down.”
“I simply told her the truth. You’re working too hard, and you need some free time, even if only a few hours.” Celestia’s hoof slid down to stroke the doctor’s hip and well-rounded ass, and Mary felt that scalding prick sawing between her thighs harden again as the Princess started to catch the mood. “She was surprisingly amenable. I didn’t even have to bring out any of the ultimatums I’d prepared. Whatever I might think of her as a person, I must admit she knows when to listen to reason.”
Mary squeezed harder with her thighs, grinding her body against Celestia’s overheated cock. Her efforts quickly bore fruit as dribbles of precome pulsed from the wide flare, making her mouth water. “With all due respect to the good Lieutenant, I don’t want to think about her right now.”
“Is that so?” Celestia’s voice was lower, rawer. “What is on your mind, good doctor?”
In response, Mary hugged Celestia’s fat cock closer to her body as she touched her lips to the tip, slurping up much of the issue from the drooling slit. The cock throbbed as it produced more silky fluid, and the dribbles became a steady flow which Mary eagerly began to drink. Her throat worked constantly as she nursed, and she felt a kind of fuzzy contentment that she only experienced in quieter moments like these. Celestia’s essence might not have been chemically addictive, but her body craved it all the same.
Celestia watched for a while as Mary suckled on her cock, then she bent her graceful equine neck down and drew her long tongue across the other side of the crown, tasting her own juices. There was no further conversation; the only sounds in the suite were the smacking of lips and the working of throats as the two of them shared the unique flavors of royal pre.
They both slid their mouths down the sides, then back up and over the top, collecting everything on the now hardened surface with a deepening hunger. Their lips met just above the wide open slit, and they kissed lustily as the Princess’ fucktool liberally splattered their faces again and again. Both their tongues were in constant motion as they savored the precome covering each other. 
Intimacy and sheer raunchiness conspired with the constant pressure of that fat prick against her cunt to send Mary higher and higher. She was almost there…god, Celestia’s lips tasted so sweet…just a little more…
“What a disgusting scene. I blame you for this, Dr. Parvotti.”
Mary gasped, turning her attention to the other side of the bed. Laying on her side directly in front of them, watching their actions with a curious intensity, was another pony.
It was another alicorn, in fact, almost as large as Celestia herself. Her skin was a deep purple, almost black, and her mane and tail were interwoven with the small, sharp lights of stars and planets. She had the same possibly-not-vestigial wings as the Princess, and an obsidian horn graced her forehead above a narrow, haughty snout. Dark, stormy eyes were filled with animosity.
Across the alicorn’s ample flank was the unmistakeable sigil of the moon. It was all the confirmation Mary needed.
“Night Regent Luna, I presume,” Mary said shakily, trying to mask her shock as best she could with a face smeared with sexual fluids. If she’d learned anything over the past couple of months, it was how to adapt to strange circumstances. “I wish you’d let me know you were coming. I’d have welcomed you properly, maybe with some light entertainment.”
“I can imagine,” Luna said, switching her focus to the alicorn behind Mary. “Sister. Have you been well? Are you eating properly? Are your indulgences still a stain upon the kingdom? You only need bother with the first two questions; I think I can figure out the answer to the last one.”
“Youngest. Your timing is…intentional as usual.” Celestia licked precome off her muzzle with her obscenely long tongue, showing a decidedly blasé attitude toward being caught with her cock in the cookie jar by her own sister. “Moments such as these only bolster my decision to come to Earth myself. Allow me to reinforce Mary’s suggestion with one of my own, except it’s not a suggestion: the next time you show your face on this side of the portal, you will announce yourself beforehand. I will not have you acting on Earth without my knowledge.”
Youngest. Mary was surprised at the absolute authority in the Princess’s voice, so different from the gentle, welcoming tone she took in her ambassadorial duties. It was the voice of someone very much used to unquestioned obedience when it was warranted. Seeing even this barest sliver of Celestia’s royal power was fascinating on a scholarly level…but it was mostly just sexy as hell.
Luna seemed to get the message as her look of disgust deepened. “No need for oblique threats. I would rather not act at all, with or without your knowledge, but never let it be said that the Night Regent did not come when her Princess called. That said…”
Luna’s acidic gaze settled upon Mary. “…it took a rather unseemly amount of time for your regrets to animate your actions. I expected to be consulted much sooner about Erin. Did that poor young woman slip your mind as you continued to satisfy your urges? Or did you plan to get to her right after your blatant sexual congress with Kurosawa’s daughter the very next week?” The Regent’s eyes bored into Mary’s. “You said some dreadful words to that girl. Hanging the fate of humankind around her neck was an especially deviant touch. I hope it was worth it to cultivate a new playmate.”
“Remains to be seen,” Mary said evenly, “but it’s looking pretty good so far.” She didn’t expect to be reminded of those moments, and she tried unsuccessfully to still her tell-tale heart. “Your bitching is more informed than I would have expected. I know Celestia isn’t one to kiss and tell, so how do you know so much?”
“I may not have as much magic as my sister, but mine works on an entirely different axis,” Luna said as she waved a hoof dismissively, and Mary noted that it was shod in silver and molded into incredibly delicate astronomical shapes. The Regent seemed to have an eye for fine detail. “My domain is that of dreams and nightmares, but powers differ outside of Canterlot. As it happens, the world of the subconscious is magically adjacent to those human technologies which capture a facsimile of the real world. I’ve found that I can inhabit those devices as easily as a sleeping mind…easier, in fact. The flying ones are especially useful.”
Mary didn’t even bother to hide her shock. “Princess, can you make sure I’m hearing this correctly? Because it sounds like your sister can hack into government cameras like I log into my work email.”
Celestia nodded, squeezing Mary a little tighter. “Cameras and microphones and displays, inputs and outputs. It makes conceptual sense. A dream is only another type of playback…confused and out of order, but playback all the same.”
Mary considered the Night Regent with a new appreciation. “Right. I get it. You’re the reason why our videos haven’t hit Pornhub, and why Lt. Kurosawa hasn’t tried to have me killed. You’re the cover.”
Luna re-adjusted herself on the bed. She seemed to be enjoying the decadent softness, despite her constant scowl. “Cleaning up after my dear sister has always been one of the more thankless parts of my job.”
“At least you get to look at some ass and titties while you do it,” Mary said, trying to counter Luna’s sourness with some levity. “So, why are you here in person? This literally could’ve been a Zoom call. Did you just want to see your big sister, or what?”
The Regent and the Sun Princess exchanged a glance, then Celestia responded with a chuckle. “I’m afraid you’re a bit out of the loop. Don’t panic, but Luna is using her more traditional methods to speak with us right now.
Mary’s eyes went wide. She was glad for the warning, at least. “Are you telling me-“
“Human minds are so much easier to invade than those of ponies,” Luna scoffed, “and yours is a wide open window. Your appalling desires…your monstrous obsessions…they’re so close to the surface that I can ride them all the way back down to your subconscious."
“What can I say? I wear my cunt on my sleeve.” Mary refused to make apologies for her behavior, but she grasped Celestia’s foreleg a little tighter all the same. “I’m assuming the Princess humping my ass right now is the real one, and not some ghost in my head.”
Celestia’s answering touch along Mary’s wrist was reassuring. “It’s the real me. I’m right next to you in the real world. Luna can’t create a copy of me in anybody’s mind; I’ve enchanted myself to prevent it for just that reason. If you ever see a Celestia in your dreams, it’s either a natural thought or because I wish it so. You’ll know the difference.”
“Such a pointless action, and indicative of an unfortunate lack of trust,” Luna said, but she sounded more put-out than angry at the sanction. “Which is fine. I can live with suspicion. I have for much of my life. That’s why I refuse to accept your relationship with the Sun Princess. Doctor.”
Luna’s look was as judgmental as Celestia’s was serene, and it made Mary grit her teeth. Yet the alicorn continued, heedless of the doctor’s shifting mood. “The things I’ve seen in your mind have shocked me to the core, Mary Parvotti. You are a pervert, a hedonist through and through, who will stop at nothing in the pursuit of sexual pleasure. Unfortunately, that means you and my sister are a perfect match for each other…in fact, I daresay you are the worse influence. I hope Celestia realizes this before she falls even further.”
“Celestia is responsible for her own choices,” the Princess said in imperious third person, “and Celestia fucks whoever she wants, whenever she wants. That’s what it’s called, dear sister. Fucking. You learned how that works, remember?”
Demonstrating the concept, Celestia gave a series of slow, languid thrusts with her cock still squeezed between Mary’s thighs, touching the doctor’s chin and cheeks with the tip and leaving sticky fluid in its wake, while her lover planted soft kisses every time the flat crown came close to her lips. Celestia made sure to maintain eye contact with her sister as all this was happening. 
“Mmm, my dear little pony. Fucking feels sooo good, Luna. Like nothing else. I know you have your own proclivities, but for your own sake, you really should try to…”
Celestia’s breath caught. “Oh. Mary doesn’t know, does she?” She gave a wide grin. “Well, we’ll have to fix that. In the interest of full disclosure, you understand.” The Princess suddenly sounded downright mischievous, which gave Mary goosebumps. For better or for worse, she’d learned to be wary when Celestia was in such a mood.
Luna’s only reaction was a slow blink. “I think the Earth atmosphere has started to affect your mind, sister. I have no idea what you mean.”
Celestia chuffed a laugh. “Mary, look at her closely and tell me what you see.” It was a trick question if ever Mary heard one, and she peered at the annoyed-looking alicorn, trying to figure out what Celestia wanted her to notice. 
After a few moments, Mary realized that Luna’s right arm was subtly working in a regular motion. She followed the limb down to the silvery hoof, where it was embedded between the Regent’s legs. A spot of clear liquid stained the sheets beneath her midnight hips.
Then, Mary caught a whiff of something. It was a familiar smell, yet subtly different from what she was used to. The undertones were softer and less musky, but there was no mistaking it.
Mary hoped her own smile wasn’t too insufferable. “Princess, I do believe I smell pussy.”
Celestia inhaled deeply through her pink nose. “I concur with your assessment, doctor. I might also add the adjectives needy and overheated. Possibly even ripe.”
Mary bit her lip, trying not to laugh. “Excellent analysis. So, Luna. How long were you watching us before you decided to show yourself?”
Luna didn’t hesitate. “Since last night.”
This time, Mary did let out a bark of laughter before catching herself. “Wow. I’m almost flattered. Seeing your big sister stretch out my tiny little human holes got you so wet you had to start hoofing yourself right then and there, huh? But we kept going in my dream, and you kept jilling. God, you still can’t stop, even while I’m talking to you. I’d almost call it rude, if it weren’t so hot.”
“It seems whatever brain disease the Princess contracted is catching,” Luna said flatly, without changing her expression one iota. “You are talking nonsense.”
Even as Luna spoke, the rhythmic motions of her arm sped up a tiny fraction.
There were blind spots, and then there were blind spots. “You like to watch. You really, really like it. You can’t even say what you need in words, but that neglected little pony pussy speaks loud and clear, doesn’t it?”
Taking a chance, Mary reached her arm out and touched Luna’s cutie mark, feeling a muscular hardness in the Regent’s wide flank, in contrast to the matronly softness of Celestia’s jiggly rump. Luna did not make a sound, and her frown did not lessen in the least, but she made no move to push the doctor’s hand away.
“Hypocrite.” 
Mary roughly squeezed Luna’s ass in her palm. The simple word was filled with all the venom she could muster, and she let it linger for a while. To Luna’s credit, she did not visibly quail at the accusation, or Mary’s harder grasp…in fact, she scarcely reacted at all. But the offending hoof ceased its motion.
“Continue to waste my time and I will leave you to try fixing that reporter’s shattered psyche yourselves,” Luna said, otherwise ignoring Mary’s provocations as she glared at the lovers. “I’m positive that neither of you have ever given a second thought about the ruins you leave in your wake as you rut your days away. Erin is simply one more loose end that needs to be smoothed down so your reputations can remain pristine. Publicly, anyway.”
There was genuine righteous anger in the Regent’s voice as she condemned Mary and Celestia. “Thankfully, whatever higher powers govern the universe saw fit to send someone to Canterlot who actually does care about those around her, who fights every day to solve problems the Princess never even sees. So by all means, keep doing what you’re doing. As long as there are people like me in the world, we’ll keep it spinning somehow.”
Sometime during Luna’s diatribe, she had moved close enough to Mary that her black nose was inches away from the doctor’s. Mary hadn’t noticed until the Regent went silent, but the sudden proximity wasn’t why Mary felt so abashed. Luna’s earnest devotion to serving the Princess, and by extension everything and everyone she was involved in, was undeniably real. It also had the sound of someone long-suffering because of such dedication. Mary’s caressing hand stopped as it lay, momentarily forgotten, upon Luna’s haunch.
Mary turned to Celestia to try to gauge her thoughts, but the Princess only wore her standard mask of serenity. There would be no insights there. She was about to make an apology when a thought entered her head.
“Wait. Did you see Erin and Celestia that night?”
“I’m glad we can start our discussion at last. Yes, I saw them both. There are cameras and microphones all over this complex, and that includes Celestia’s rooms.”
Mary frowned. “Lt. Kurosawa told me the suite interior didn’t have cameras.”
“Bullshit, of course,” Celestia said mildly from behind her. “I’m sure my sister could examine us at angle she wanted, anywhere in the room.”
“Correct,” Luna said. “There are more monitoring devices in this suite than in the rest of the building combined. For obvious reasons, I suppose.”
It still seemed a little excessive to Mary, but that was beside the point. “Let me put it another way,  Luna. You were watching them. The whole time. Weren’t you?”
“I was,” Luna snapped. “And before you speak further: I couldn’t have stopped what was happening. When Celestia is in that…state…all I can do is try to minimize the damage after the fact. My sister is many things, but weak she is not. Forcing the issue never works. Trust me, I’ve tried.”
“I wasn’t about to make that accusation,” Mary lied. “But, I am going to make a different one. Your body liked what it saw, didn’t it? You were getting off to them, just like you were to us a few minutes ago.”
“Why would you say something so absurd?” Luna was close enough that Mary could see down her throat as she spoke. The doctor idly wondered if the Regent still had her gag reflex as she continued angrily. “I thought we were taking this seriously for a moment. If that’s not the case-“
Mary’s hand on Luna’s flank resumed its brazen exploration. “I want a simple answer, Luna. Yes or no. Were you hoof-fucking yourself while Celestia was long-cocking Erin? Tell me, Youngest.”
Luna’s eyes blazed with indignation. “You have no right to call me that, human-“
“Her name is Mary,” Celestia interjected firmly. “Horsefucker if you’re nasty, but I suggest you stick with Dr. Parvotti. You will answer her question, Night Regent. Yes…or no.”
The tone brooked no argument, and Luna knew it, just as she knew her sister already knew the answer. She hesitated only a couple of seconds, and when she next spoke, all the pique in her voice was replaced with a flat monotone. 
“Yes.”
> Chapter 2
> --------------------------------------------------------------------------

The hand on Luna’s cutie mark crept rearward, until Mary’s searching fingers brushed the ring of the Regent’s darkest orifice. Testing with a single digit, Mary was astounded at how tight and resisting her asshole was, and the doctor had to remind herself that not everyone got down like herself or Celestia, as popular as it was to talk about the wonders of the booty in modern times.
Then again, Luna’s preferences weren’t exactly vanilla. Even with full control of the Dreamworld, save for Celestia, she didn’t try to pull away from Mary’s grip.
“At least you won’t lie to other people,” Mary said. The royal siblings possessed a core of alicorn nobility that made it impossible for her to dislike them altogether, no matter how depraved their actions. That probably said more about Mary than the alicorns, though.
“I can say with pride that my dear sister’s honesty was not something she learned from me.” Celestia really did sound pleased, which Mary found adorable. “She’s been like that since we were foals.”
“Isn’t that just the sweetest?” Mary said, pleased for a very different reason. “This conversation should be simple, then. Let’s start with a softball. Luna, did you know Celestia was on the hunt for pussy during that banquet?”
“I did,” Luna said. Her speech pattern was not exactly robotic, only neutral, without overly emphasizing her words. “I didn’t know who she was targeting, but I did know she was looking for a partner for the evening.”
She sounded…practiced, as if she were trying to disassociate herself from the questioning, and that clearly wouldn’t do. Mary’s teasing finger dipped deeper into Luna’s anus, wedging it open another millimeter. The only reaction was a quiet intake of breath, and it was music to Mary’s ears.
“Of course she was. Well then, dish it up. Knowing Celestia’s tastes, who did you think your sister would be going home with? Was I anywhere in the running?”
Luna’s perpetually angry face was tense, but she kept her voice light as she shook her head. “I was positive it would be Erin in the end. Celestia has been known to use alcohol as a…lubricant, and Erin’s love of wine is common knowledge. The rest fell into place just as I’m sure my sister planned it.”
Mary gave Celestia a playful side-eye. “Fuck, Princess. Why not just go all the way and put a little Spanish Fly in her glass? Couldn’t close the deal otherwise?”
Celestia replied haughtily. “Being charming is what I do. I have no doubts about my ability to land a piece of ass, but I also wasn’t going to stop Erin from enjoying her drinks. She’s an adult, after all.”
“If that’s what you want to tell yourself,” Luna said in that strangely even tone. “We’re thousands of years old, but that wouldn’t matter, would it?”
For once, Luna and Mary were in agreement. “Most people have to choose between age, beauty and power. Not exactly a fair fight when you have all three, not to mention the whole ‘being an alien princess’ thing. Okay, Luna…what happened after the party?”
The slight reddening of Luna’s cheeks was growing more visible. “Yes. After Celestia invited Erin up to her room, she had her enjoy a couple more bottles of her enhanced red while they relaxed on the couch. They started getting…familiar, flirting with each other shamelessly. Then, they began talking about their s…sexual fantasies.”
“Oh, that sounds promising,” Mary said. “Pray tell.” She was actually more interested in Celestia’s response. What kind of fantasy would the Princess reveal to a hookup she just met?
For the first time, Luna averted her eyes from Mary, and she hesitated an unusually long while before responding. The doctor found it hard to believe that she was such a puritan about others’ fetishes, but her reactions spoke volumes.
“Erin…she…her fantasy was to be taken in the most inappropriate places,” Luna said quietly. “Like in a tense meeting, or in line at a grocery store. Wherever it would be least expected, and in front of as many observers as possible. I still find it shocking that those words came out of her mouth.”
Mary’s other hand began to trace a long path from Luna’s elbow downward, toward the cunt the Regent was still stroking, despite her protestations. With Celestia’s fat cock still rigid against Mary’s chest, it was as if she were embracing both alicorns at once.
“‘Shocking’ isn’t the same as ‘not hot,’ Mary said. “Erin was probably hoping Celestia would throw her across the table and fuck her at the party, in front of a dozen world leaders. I don’t think even you could clean up a diplomatic incident like that, but hell, it might have been worth it.” 
The Princess had come to the same conclusion. As Mary spoke, Celestia’s thick meat throbbed just below her face, painting her left eye closed with a long spurt of pre. Another quick gasp came from Luna’s lips at the sight, and Mary tried not to grin through the sudden creamy adornment. 
“I…I’d have to think of something, because I wouldn’t be able to stop the Princess,” Luna said, her eyes on the wetted tip of Celestia’s prick. “Not me, and not anyone else. “
“Wouldn’t matter if they brought an army to try to stop her,” Mary agreed. It was just the basic fact. “They could’ve nuked the bitch, and she wouldn’t even notice. Celestia doesn’t quit a fuck until her balls are empty, and if Erin didn’t find that out at the banquet, you better believe she learned it later.” Another spurt of precome landed in Mary’s hair, in confirmation.
Luna seemed fascinated by the milky fluids covering the doctor’s face. “Why do you let her do that to you? How could any self-respecting person stand it, let alone find it desirable?”
Mary chuckled, but instead of answering directly, she moved her hand down to Luna’s hoof, feeling soft wetness and heat behind the hardness of the silver.
“What about Celestia’s fantasy? What did she tell Erin? Come on, Youngest, speak up.” Mary’s fingers reached Luna’s clit, as large as a marble and almost as hard, and the Regent’s breathing became labored. Still, she didn’t answer right away, glancing at the Princess with an almost pleading look.
Celestia stared back impassively. “Tell her, dear sister. Hold nothing back.”
Luna bit her lip in frustration, but the hoof stroking her soaked cunt began to move noticeably faster under Mary’s hand. The doctor was amused at how readily Luna had given up on trying to disclaim what she’d obviously been doing.
“Thou art a terror, Princess. Wouldst thou have me reveal thine secrets in such a-“
“Watch your tic, sister. You asked me to remind you about that, remember?” In a stage whisper aside, Celestia said to Mary, “She gets like that when she’s flustered. It’s cute, isn’t it?”
“God, yes,” Mary said, pleased that she was able to get the Night Regent to let down her guard so thoroughly. “Luna, if I ever let you get a taste, I want you to talk like that while you’re tongue-fucking me. Now answer me, you goddamned mule. What did Celestia tell Erin?”
Luna’s pink tongue slipped out of her mouth and licked her dry lips. “The Princess saith…she said…she liked to imagine herself urinating on people…in front of other people. She said she often had the urge when she wanted to show her superiority. I…had never heard that from her before.”
Was that jealousy in Luna’s voice?
“Guess it’s only natural,” Mary said. She’d never heard Celestia mention such urges either, but she wasn’t surprised in the least. “It’s what beasts tend to do. And if there’s anything the Princess knows about, it’s bestiality.”
“Only because I’ve been fucking a smart-assed little vixen,” Celestia said, bopping Mary on the back of her head with her muzzle. “But to the point, I think about unloading my bladder on people constantly. Out of nowhere, in the wrongest circumstances. Maybe that’s why I sympathized with Erin so much.”
Mary doubted there was a right circumstance for pissing on someone in public. “How did Erin take that? I imagine the response was…favorable?”
Luna’s hoof passed the borderline of her fiery cunt’s entrance as she began to press deeper, and though it was still hidden by the Regent’s thick thighs, Mary’s could hear the squelch of that juicy pony pussy as it accepted the digit. Luna let out the tiniest moan as she hoof-fucked herself, spurred on by Mary’s expert handling of her big, sensitive clit.
“Ah…Erin…she was surprised at the Princess’ depravity…but she was also intrigued. She said it would be difficult for a woman to dominate someone so casually, since they didn’t have the right equipment. And then…my sister…she…”
“I arose from the couch,” Celestia said, too excited to wait for Luna’s telling, “and I released my invisibility spell. I gave that little pony her first good, long look at Princess cock. Then I watched the juice run down her legs as she came in her pretty little panties.” The pride in Celestia’s voice was unmistakeable, and she gave a few rough thrusts of her prick against Mary, stimulated by her memories. “The poor woman was on a hair trigger from the beginning. Once she saw what I was packing, she hadn’t a chance.”
Luna’s gaze was now locked onto Celestia’s rampant prick, and her other hoof twitched, as if wanting to touch the slab of fuckmeat between herself and the doctor. Mary gently reached behind herself to tap Celestia’s wide flank and, sensing what her partner wanted, the Princess reared her hips back, moving her cock from between Mary’s thighs and re-adjusting herself so the broad shaft was now against the doctor’s back, nestled snugly between Mary’s ample ass cheeks.
Luna’s face fell, like a child losing access to a new toy. But now, there was nothing between Mary and the Regent, and they were close, close enough that Mary could make out the constellations in Luna’s starcrossed mane. The doctor’s sticky fingers left Luna’s straining clit and went to her mouth, where purple lips parted and a small, tenuous tongue snaked out to taste a cool, almost minty essence.
“Sounds like we’re just getting to the good part,” Mary whispered. “Keep going. What did your sweet sister do then?”
A long string of saliva broke between Mary’s thumb and Luna’s lower lip. “My sister…she began to urinate. Mary, she aimed herself directly at Erin’s face and chest! The Princess didn’t even smile, or look excited…just relaxed, as if she were relieving herself on a toilet, instead of a person!”
“I gave her what she wanted. What she needed,” Celestia said as she slowly rutted against the cleft of Mary’s ass. “She opened her mouth and drank every drop, all while coming so hard I could see every contraction. So sensitive, that one.”
Mary was feeling rather sensitive herself, hearing the sisters’ story. She raised one knee, opening herself fully to Luna as she abandoned her exploration of the Regent’s ass, grasping a free hoof and drawing it to her own sloppy cunt. She moaned shamelessly as she used the silver-shod digit to play with herself like it was a sex toy, while Luna looked on in confused arousal.
“You gotta show me that damn recording, because I’d bet my right tit you made one,” Mary hissed as she stroked herself. “Sounds like Erin knew exactly what it meant to be marked by a fucking animal.”
“Uh….ahh…” Luna groaned, overstimulated by the simultaneous giving and receiving of pleasure. “She knew more than you realize…because-”
“Because the next thing she did,” Celestia said in a husky growl, “was turn around to point her pert little ass and juicy cunt in my direction. She pulled her panties down to one ankle, and just…waited. Without a fucking word, she just knelt there on all fours like a dog in heat, presenting herself. Waiting for my fuckmeat to stretch her out, and take her virginity all over again.”
“No way the fat-assed pervert behind me would ever turn down an invitation like that,” Mary said fiercely as she hunched herself against Luna’s hoof. Her own dumper clapped and clenched against Celestia’s prick, and she felt surrounded by pleasure. “Bet the Princess mounted her right there…tilted her ass into position, lined it up with her fat cock head, and tore that sweet little pussy wide open. Didn’t even give her a chance to say no…not that it would’ve helped. Tight little tease got just what she asked for, all the way to her fucking womb…”
Mary trailed off, grunting savagely, and her hip motions became more erratic. She clutched Luna’s wrist with an iron grip as she plunged it deeper into herself, until finally the hoof sank completely into Mary’s grasping cunt. The doctor groaned with the sensation of fullness, and she couldn’t hold back the familiar orgasmic waves rippling from her core.
“I’m…I’m gonna come. Watch me, Luna. Watch me get off, right in front of you. You wanna see it, don’t you? What would your dear sister think? Fuck, gonna cream so hard…don’t turn away! Look at me, goddammit! Fuck…ah, fuck…!”
Luna trembled as she obeyed, holding Mary’s wild gaze as the doctor finished herself off with her hoof. Splashes, then streams of fragrant come spurted from Mary’s wide open snatch, soaking Luna’s chest and even reaching to her face. The doctor groaned, letting go completely as she tilted her cunt up and down in a fucking motion, flinging her wetness all over the alicorn in front of her.
Excitement and terror fought across Luna’s face, and her breath came fast and hard. “This is not what I want…Celestia, this is not who I am! This hu…Mary has tainted me, just as she tainted you! You have to-“
“Do you think I don’t know how much of a freak you really are?” Celestia asked, embracing Mary from behind as she enjoyed the doctor’s jerking ass against her cock. “Or always have been, I should say. If only you could watch yourself as carefully as you observe others. But aside from that…there’s more, isn’t there? Erin was not a silent fuck. You remember the filth that came from her mouth, don’t you?”
Something broke in Luna as she processed Celestia’s words. Even Mary, coming down from her Kegel-clenching orgasm, could sense a change in the Night Regent’s psyche. The scowl disappeared, replaced with resignation, combined with a newly unrepressed lust behind the dark eyes.
Mary allowed herself a hidden smile. It certainly hadn’t taken long, had it?
With a shameless moan, Luna slipped her hoof out of Mary’s messy cunt, causing the doctor to grunt as even more cream dribbled out of the forced-open hole. Luna took the same hoof and pressed it into her own tight asshole, opening her muscular thighs so all could see. The silvery tip slowly, insistently sank into the dark ring of her anus, and she groaned at the unfamiliar sensation, though she did not stop.
“Erin called you ‘mother’ the whole time,” Luna said through clenched teeth as her hoof went deeper into her virginal asshole. 
“‘I love you, mother. Be gentle, mother. Destroy me, mother.’” Celestia’s recall was perfect, as usual.
“It was a role you took on gladly!” Luna cried, though the excitement behind her accusation was unmistakable. “Her sobbing was so loud when she asked why you were hurting her, then she begged for more, waving her ass like an animal. She pleaded with you to go slowly, then she cursed at you when you did. And when you sank home, all the way into her womb, that laugh…I didn’t know if I was hearing insanity or fulfillment…oh, sister! There was something already there, a wound that you thoughtlessly tore open with your…your cock!”
It was more or less what Mary had guessed. There was some kind of trauma in Erin’s past, probably from her childhood, that resonated with Celestia’s particularly insistent bedside manner. Her mind began to conflate the old, buried emotions with the current ones, but she couldn’t deal, forcing her tryst with the Princess deep into her subconscious. Hence the nightmares, even after the mind wipe. 
They needed to figure out a way to untangle those neuroses if they ever wanted Erin to have a good night’s sleep ever again. That much was clear. However, Mary had a much more immediate goal at the moment.
“Turn around, Luna.” It was not a request.
“W…why?” Luna whimpered in a voice that was far too timid coming from a member of a royal household.
Mary furrowed her brow, as if she were speaking to a simpleton. “Why do you think?” She pinched Luna’s hard clit every so slightly, just enough to make the alicorn moan. “I won’t ask again.”
The doctor had no clue what kind of mental gymnastics the Regent of a fantasy kingdom had to perform in her head to justify taking orders from a human, but she was pleased to see that the calculation worked out in her favor. Slowly, Luna turned her back to Mary, showing off her round, moon-emblazoned ass. She still had a hoof-tip stretching her little back-door, but Luna was being far too timid. They’d need to hurry that process along.
Groaning with lust, Mary slid down to face that juicy ass. She gave it a slap, pleased to hear Luna’s answering eep as she watched the furry flesh jiggle. Prying the cheeks open, she roughly pushed Luna’s hoof out of the way before shoving her face into the Regent’s big butt, tasting the thick ring with her searching tongue. It was different than Celestia’s; whereas the Princess’ asshole tasted of musk and sweat, Luna’s was like alcohol, reminding Mary of vodka and other clear spirits. Her anus was literally intoxicating, and the doctor wondered what she ate to make it that way as she dove deeper into the booty.
“Ah…ahhh! Oh, Mary…you can’t, that’s disgusting, don’t put your tongue there…please, you have to stop!”
Mary lifted her head out of Luna’s backside, giving her a challenging look. “We’re in the Dreamworld. The fuck are you whining at me for? Make me stop.” She then pushed three fingers into Luna’s sucking ring. “Otherwise, try to relax. My entire fist is going up your ass, so you might as well get used to the feeling."
Mary chuckled as she heard Luna’s excited protestations. “You wouldn’t dare! It won’t fit! I forbid it!” She said these things as she reached around, spreading her ass wider, trying to ease the fist’s passage. Ignoring the Regent’s pleas, Mary slid a fourth finger in, feeling the powerful anal muscles clench around her digits. Being a buttslut seemed to run in the family.
“What about your fantasies?” Mary asked as she worked her fingers in and out of Luna’s ass. “You were watching after our meeting with Kurosawa last week, weren’t you? Did that scene get you wet?”
Luna gave another frustrated moan, before nodding. “The scenario you described…taking someone that proud against her will, making her break on my sister’s cock…I was ashamed, but it was all so…dangerously vivid!”
Mary could hear Celestia’s rough breathing behind her. She wouldn’t be content with just exterior friction for much longer; the urge to breed was becoming far too strong. 
“What was the best part?” Celestia growled. “When I sprayed her with my precome? Or when I slapped my fat cock on her chest, showing her exactly how fucked she really was?”
“It was when you made her come!” Luna almost screamed the answer. “When Mary held her in her arms, and she came and came on your cock while crying with the shame! Making a soldier lose control, making her body betray her, that was so incredible-“
Mary’s thumb joined the rest of her fingers, finally completing the set that was now fully immersed in Luna’s colon. She made a fist, thrusting in and out firmly while examining her next target: Luna’s dark purple pussy, already slathered with sticky cream. Mary licked her lips at the feast as Luna convulsed above her, jerking her hips uncontrollably.
“How are you…you’re making me…uh, uh…” Luna temporarily lost the powers of speech as her orgasm overtook her at last.
“Look at you, coming from your ass,” Mary said savagely as she put some force into her thrusts, more or less punching Luna’s lower intestine. “You’re as much of an anal whore as your sister.”
“I sincerely doubt that,” Celestia said with something like professional pride. “How about when we tag-teamed that barely legal piece on the beach? Did you enjoy watching us break her in? Julie worships my cock now, did you know that? She’ll never be the same again.”
“You’re always…so proud,” Luna said, panting in the come-down. Mary could hear her teeth chattering with her aftershocks. “So damned proud of ruining people. The poor girl fell in love for the first time in her life, and she’ll never again be fulfilled by normal sex. But to you, she’ll always be just another conquest, to be mind-wiped whenever she becomes too inconvenient.”
Luna placed a hoof on Mary’s head, taking control for the first time as she directed the doctor with gentle pressure toward her waiting snatch. “In her dreams, Julie imagines she’s your slave. She has willingly collared herself, committing to you body and soul…ah! She’d die for you without hesitation! And you love it!”
Luna made a soft huffing noise as Mary scooped a tongue-full of silky cream from her gaping cunt. The doctor embraced those wide hips, caressing Luna’s dark backside as her mouth latched onto the tasty pony pussy, drinking in the Night Regent’s juices like one dying of thirst. Mary found the flavor cool and refreshing, akin to menthol. It was another striking contrast with her sister.
“Ahhh, Mary, Mary…you both know you’re the last people who should have that kind of responsibility! You’d use Julie like a toy, like a pleasure tool, without even the least regard for her as a person, and that’s exactly what she wants!” Luna moaned as Mary tongue-fucked her in a rhythm with the fist in her ass, no longer trying to hold back the sounds. “Maybe you’d pass her around to your friends. It would make her so happy to be your whore. That’s how much you’ve corrupted her mind. Do you…ohhh, damn it all…do either of you have even the slightest remorse?”
Mary considered the question as her tongue reached deeper into Luna’s channel and she nestled her nose firmly into the alicorn’s taint. She decided that, no, she felt absolutely no remorse about breaking Julie. Not about luring her out under a false pretext, not about hiding the relationship from her mother, and definitely not about making her into a horsefucking cumslut size queen.
Of course, behind all this was the real unasked question, and Mary decided to confront it head-on as she licked the fragrant cream from her lips. “I couldn’t let her go, Luna. I had to think of something. I’m not proud of the way I manipulated her, but I’m not sorry about it, either. It’s what she wanted in the end. She just needed a push, that’s all.”
“Your justifications are almost as amusing as Luna’s,” Celestia said, probing Mary’s reddened, gaping cunt with a hoof. The Princess was almost at the end of her patience. “As for myself, I’ve long ago made peace with my own morality. I do feel regret, but I’ve learned to…compartmentalize it. I can examine my conscience without letting it hold me back. After the incident with my dear apprentice, I understood that it was a skill I needed to learn.”
At Celestia’s last sentence, Mary felt Luna’s anus clench painfully around her wrist, and the flutter of vaginal contractions almost ejected her tongue from the Regent’s tight cunt.
“Holy shit, Luna,” Mary said, riding out the alicorn’s reaction. “That feels like a story I need to hear.”
Luna suddenly turned around, almost choking Mary between her legs as she faced her sister. “You cannot. You must not reveal your shame, Celestia.” She was frantic, almost incoherent. “I beg you, please! Do we truly have no secrets as sisters?”
Celestia was Princess-level serene as she enjoyed Luna’s distress. “I keep very few secrets from Mary, it’s true. And I’m afraid, dear sister, that this one does not rate.”
Luna’s eyes went wide. “But…but you almost…”
“What?” Celestia’s voice was even. “I almost what, Luna? Say it clearly.”
Mary listened to the exchange, fascinated. Whatever they were talking about sounded unusually scandalous.
“It is beyond the pale!” Luna cried. “You…you almost took Twilight Sparkle against her will-“
“I said, say it clearly. I almost raped her, and I would have, if not for you. There. Now that I’ve done the hard part, you can fill in the details.”
Mary suppressed a gasp. Scandalous wasn’t quite strong enough. Threatening was closer.
“Go ahead, Luna. Do what she says and fill me in.” The doctor formed the hand not in Luna’s asshole into a wedge shape. “Meanwhile…I’ll fill you in.” She slipped the hand entirely into Luna’s frothy hole, finding very little resistance due to the incredible wetness of her cunt, and she began to slowly pump both hands deeper into the Regent’s body.
Luna grit her teeth as she endured the dual fisting. “Not right…none of this is right! That was a tragic event, never to be repeated, one of the lowest points of Celestia’s reign, not a seed for your twisted fantasies!”
“Fantasies don’t always follow the rules,” Celestia said, intently watching Mary go to work on Luna’s holes. “I’m sure you didn’t wake up this morning thinking you’d be taking human fists in your ass and cunt, even in a dream, yet here you are. And if you tell me you won’t think about these moments in the future when you’re getting yourself off, I’ll call you a liar. Are you going to lie to me, Youngest?”
Luna grunted at Mary’s powerful thrusts, and she gave a sharp shake of her her head in acknowledgment. “Corruption,” she groaned. “Evil influence. You are a danger, Mary Parvotti, though none of this began with you.  The Sun Princess has never, ever been innocent, but that day, all those years ago, was the beginning of something…”
She gasped, catching herself, and Mary grinned as she continued to pump her fists in and out of the Regent, occasionally opening her hands to caress certain special places inside. It sounded like Luna was about to say ‘something special,’ which would obviously be inappropriate, even if it was the truth.
Based on Celestia’s knowing look, she’d been thinking something similar. “Let’s just call it a catalyst,” she said. “It would have been about a hundred years after Twilight’s ascension, so three hundred years ago, give or take.”
Celestia sighed at the memory, and Mary felt the Princess’ fat prick throb mightily against her backside. “She was still so excited, trying to learn everything she could about alicorn physiology. Even after a century of research, Twilight was still making new discoveries. Such a brilliant apprentice, that one.”
Mary fought down the twinge of jealousy creeping into her heart. Celestia had lived a long, long time, and she’d surely had many friends and lovers in all those years. Mary had always tried her best to understand that she was not the only person in the Princess’ life, or even the most important. She let the brief wave of melancholy pass through her, acknowledging it before letting it go.
“We actually agree on something,” Luna said, and she gasped again. “Ahhh, Mary…you’re going to make me come again if you keep doing that!”
“Then you better talk fast,” Mary said, moving her arms like pistons against Luna’s insides.
Celestia gave Luna a reprieve as she set the stage. “I’m sure you remember, sister. We were in my chambers, early in the afternoon, and we’d been talking about giving Twilight more responsibilities. I wanted to let her gain more practical experience in local statecraft before offering her an ambassador role.”
Luna moaned as the memories of that day combined with her current feeling of pleasure. “We’d just finished our tea, when Twilight came barreling in like a hurricane, as she often did. She started ranting to us about a new strain of poison joke, carrying a handful of it in with her, saying she wanted to cultivate it as a soporific. Mmm…she was always so damned single-minded…and maybe that’s why she didn’t anticipate what happened!”
Celestia snorted with lust, and her hooves were in constant motion, touching and caressing Mary everywhere from her dark, eraser-tip nipples down to her meaty ass, and then further between her thick thighs. Mary sniffed, detecting the gamy aroma that only came from Celestia’s loins when she was on the edge of control. She was barely holding onto herself.
“I felt it immediately,” the Princess said roughly. Speaking was coming harder for her. “Whatever Twilight did to those herbs was incredibly effective. I can still remember the scent of peppermint permeating the room. But she’d made a rare miscalculation. Mary, I need to fuck you before I go insane.”
Mary grinned, but she did not immediately acknowledge Celestia’s plea. Instead, she looked up into Luna’s lidded eyes, shaded with lavender. “I bet I can guess the actual effect of that stuff.”
“It affected us both!” Luna moaned to the sky. “I’ve never felt such a strong aphrodisiac…I had to fight with all my strength to keep from…from masturbating right there in the drawing room! And Celestia…oh, Mary, I still remember her face, so full of wanton need! It was the most frightening…the most dangerously erotic thing I’d ever seen!”
“That silly little pony,” Celestia grunted. Mary could hear the soft schlicking sound of the Princess stroking the slab of meat between her legs as she kept herself on edge. “Silly, sexy little Twilight. She was going on and on about medical trials and seed beds or whatever. I just wanted to ruin that fucking cockteasing twat right there. I didn’t care about my sister next to me, or the guards outside the door. I wouldn’t have cared if we were in a full throne room.” 
Celestia slowed down her stroking, gasping as she fought to keep from going over. “My cock has never been harder than it was at that moment, Mary. And then that oblivious little pony turned around to get a book on botany from one of my lower bookcases. All it took was a good look at that firm ass and that tiny, tight little slit, and I had to have her. I had to, Mary!”
“I couldn’t stop her!” The doctor couldn’t tell if Luna was crying or laughing. “Twilight never saw it coming. Before I knew it, my sister had mounted her student, and she was trying to line herself up…Twilight fought against her grip, but my sister was so strong. She never should have been able to escape, but Celestia was too far gone, too bestial, and she couldn’t…find the hole. That was the only thing that saved Twilight’s chastity.”
“All I wanted was to fuck,” Celestia snarled. “I just wanted to sink my cock into some virgin cunt, but that panicky filly wouldn’t stop struggling. I had to bite her neck to get her still enough to let me pop that sweet cherry. But then, my dear sister had to play the hero by knocking me away.”
“Forgive me!” Luna’s shout was strange, given the circumstances, but Mary figured that sisterly bonds ran deep. “I had to keep you from making a mistake! I took the only chance I could, shoving you off her while you were still confused, then I threw her out of the room and locked the door behind her, commanding her to run! Oh, imagine what the guards thought!”
“I’ll tell you what I thought,” Celestia said in a low voice. She jerked Mary’s legs wide apart and adjusted her own hips, angling her fat cock so that the flat head pressed against Mary’s gushing cunt. They both grunted as the Princess stretched open Mary’s entrance with steady pressure, finally deciding to take what she wanted.
“I thought Luna looked like a…ripe piece of fuckmeat…leaning against the…oh, fuck…against the door like that, showing off her dripping slit…yeah, take it all, little pony.” Celestia moaned as she sank deeper into Mary’s channel, causing the tell-tale shape of Princess cock to appear along the doctor’s chest.
Mary’s breath came in sharp gasps as she experienced the familiar, filling stretch of Celestia’s monster working its way up to her womb. “Oh, God, Luna…it sounds like somebody was…gonna take some cock that day...no matter what! And since the Princess…come on, fuck it to me bitch, fuck that pussy…since she had no control over herself…that makes what happened next your fault…doesn’t it?”
It was an absurd conclusion, of course, but Luna was in no position to argue with one fist in her cunt and another in her ass, both reaching places she’d never have been able to herself. “I had to! Someone had to be the sacrifice! You don’t understand…my sister was out of control! She might have attacked anyone to sate her lust!”
Or, she could have just rubbed a few out to calm down. Hindsight was 20/20.
Luna opened her legs, shamelessly meeting Mary’s sharp jabs with her own hip action. “Deeper. Deeper, damn you. Make me remember…or make me forget. I can’t tell what I want anymore. What have you done to me, harlot?”
The Regent watched, fascinated, as Celestia hilted herself completely into Mary, causing the doctor to make a mess of the sheets with her spending: first from her spurting orgasmic juices, then from the contents of her bladder as she blissfully lost control of herself. As she came and came, Mary had just enough self-awareness to moan, “It was…your first time!”
Luna gave a small nod as she felt her own release approaching. “I was at the door, with the guards on the other side asking what was wrong. I…I told them everything was fine…but as I said so, I heard Celestia behind me. She was so quiet…like a tiger on the prowl. Until there was no escape.”
Her legs began to shake, along with her voice. “I was so wet, Mary. I was inflamed. I knew what we both wanted, even though we were sisters. Maybe because we were sisters. Even as I spoke to the guards, I was spreading my legs, bracing myself. Preparing to be…to be bred!”
Luna could say no more. Her eyes rolled up into their sockets as the contractions began once again. But this time, something strange happened. 
Later, Celestia would posit some sort of magical rapport sparking between two beings at the height of pleasure, though she was never able to say for sure. 
Mary closed her eyes as she suddenly felt a wave of dizziness. When she opened them again, she was staring at a large, beautiful wooden door, and she could feel herself being brutally fucked against it by a cock that was outstandingly large and thick. The one doing the fucking was using full, lengthy strokes, without a care in the world for the cunt she was breaking. 
The steady thump, thump, thump against the artfully carved surface was loud enough to echo, and Mary, knowing immediately where she was, also knew that the guards outside the door could hear. It didn’t matter. She was merely a sleeve for her…for Luna’s sister to slake her thirst, and that was all right. It was what she deserved for not foreseeing anything, for not being a better retainer. A better pony.
“Lose yourself in the stars!” Mary screamed with Luna’s voice, feeling hot breath against her neck. “Hold nothing back, dear sister! Deliver the sun’s retribution, and set yourself free!” The words sounded familiar somehow. 
Mary/Luna looked behind herself, and she beheld a demon, with pure white eyes and a rictus grin, flecked with foam. Celestia’s riotously colored mane whipped as she thrust, burying her monstrous cock again and again into the Night Regent, knowing nothing but the drive to empty her bloated nuts.
No…Luna was no longer the Night Regent. She was a fur-lined hole in a fence, nothing more. She was a receptacle for come. “And that was my desire,” Mary/Luna sighed as her vision went dark. It was impossible to know which mind expressed that final thought.
When Mary opened her eyes once more, she found herself staring up at an equally bewildered Luna. “A dream within a dream…impossible! And you saw everything…all our shame!”
“I saw everything,” Mary confirmed as she bit her lip, feeling the present Celestia being no less gentle with her all too human pussy. She was being railed hard, just as she liked it, and every slam of the Princess’ wide hips against her own took her breath away. “How does it look from a different point of view? Watch her fuck me, Youngest. Watch her stretch me out and bloat my womb with her come. Is this what she did to you? Was it this raw, this nasty? Did she break you like she’s breaking me?”
Luna may as well have been viewing a slow motion car crash. “I don’t…oh, no…oh, no, no…her c-cock is so hard…she’s devouring you…but you’re taking it! Is she tight, dear sister? Are her insides that warm and wet? Did I feel…just as good?”
Celestia did not answer. Her entire focus, her entire existence revolved around getting her rocks off, and nothing else. She snorted like a bull as she fucked into Mary, drawing gooey schlicking noises from their union, and her hips moved faster than a dog’s, going body-deep with each needy thrust.
Mary’s arms slipped out of the grips of Luna’s holes as the Princess carried her to climax. She reached up silently with sticky wet hands, and Luna slid herself down the bed to Mary, letting the doctor cradle her star-shone head. Luna looked unsure, turning her eyes away, but Mary spared no time for such modesty as she grasped her by her black horn and shoved the Night Regent’s lips against her own.
After a hesitating moment, Luna forcefully returned Mary’s urgency, and saliva ran down their faces as they drank each other in. Before the day began, they were strangers, and now they were sharing a level of ecstasy that most mortals could only dream of. Mary herself was fairly confident in her own contribution to the level of heat in their Dreamworld, but you could write a book about the pleasures of alicorn sex and still have enough material for a sequel. As it turned out, living a long time as a magical being had its rewards.
Mary felt a looming shadow darken Luna’s sparkling mane, and the Regent gasped at something out of Mary’s field of view. Then Celestia’s opalescent head forced itself into their intimate space, and her scandalous tongue joined the doctor’s and Luna’s as they shared a sloppy three-way kiss, as forbidden as it was sensual. Mary was delirious, with the blazing heat of the sun behind and the cool dark of the moon in front, and as the two opposite extremes of energy circulated through and around her cock-ruined body, she found herself experiencing a clarity and resolve that she’d never had before. 
Mary realized that she would do anything to feel this way. She would lie, she would dissemble, she would deliver wounds and she would take them upon herself as long as she was rewarded with this feeling, this glorious feeling, when all was said and done. Mary wondered if Celestia might have undergone such an epiphany that day in her drawing room, so long ago.
She wondered if it was happening to Luna now.
She hoped so.
Celestia’s groan of release came to Mary through their rampant lips, and the vibrations of the Princess’s oversized balls traveled across the doctor’s body and into Luna’s, causing the latter to moan in sympathy. Celestia’s ravenous breeding tool fulfilled its purpose as it throbbed mightily with each pulse of come that forced its way into Mary’s womb, rounding out her midsection even further. The leavings of Celestia’s prodigious load splattered around the tight seal of Mary’s cunt, making a mess of both Mary and Luna’s lower bodies.
Luna hissed in shock as streams of Celestia’s scalding hot come roped against her unprotected pussy. And as the Princess’ eruption made Mary squirt her love one final time, the doctor grasped Luna’s hooves with her hands and dragged them to her belly, where she was taking everything Celestia had to give.
The Night Regent whimpered and shook as she came again, feeling the sloshing pressure of that come load, knowing it was only by Celestia’s leave that Mary was still alive. 
No words were exchanged; indeed, none were possible as they all made sounds like animals, indulging in each other without a care. And if the three of them shared any kind of simpatico thought as they drove each other to their peaks, it was only this: if we can make each other feel so good in a dream, what would real life be like?



Mary sat up in the bed, piled high with overstuffed pillows and blankets. She had a disorienting feeling of unreality as she looked around Celestia’s suite, trying to figure out if she was really awake. The play of the light still said morning, but the sun outside the full length windows was getting higher in the sky. Some time had passed, then.
“We have a plan to deal with Erin.”
Mary blearily turned toward the voice. Celestia was curled up in front of the desk next to the bed, and her pure white horn glowed as an elaborately feathered writing utensil scratched a message against a scrap of parchment, both floating in front of her. The thick Princess cock between her legs was hidden away once more, and Luna was also nowhere to be seen.
Mary yawned and stretched, still feeling tired after the events of her dream. “You two worked that out on your own? Would have been nice to have been involved.”
“You were,” Celestia said. “In your own way. The idea was mostly my sister’s, and she was ‘inspired’ by you, as she put it.” Celestia finished her missive, and as both the pen and parchment vanished in a puff of multicolored magic, she looked at Mary with her ageless expression. “You seem to have made quite the impression.”
“Feeling’s mutual,” Mary said, and a shiver went through her body as she recalled the night’s exertions. “I just hope she loosens up a little after all this. That dizzy alicorn is more insecure than Julie, which is saying something.”
“Is it saying, ‘please take advantage of me?’ Because that’s what it sounded like,” Celestia said with a gentle smile. “Although, maybe she needed someone to take her in hand. Centuries-old habits can be difficult to break, but it only takes a crack in the egg to see through to the other side. Desire does the rest.”
When Mary tried to arise from the bed, she found herself being pushed down by an unseen force. “We still have plenty of time before our duties,” Celestia scolded. “Get some sleep…some real sleep, because you’ll need it. Erin’s bedtime is around midnight, and we’re going into her dream tonight. I’ll explain the strategy later.”
Mary knew better than to argue. She fell back gratefully onto the decadently soft pillows, but before she drifted off again, she had a sudden thought. She hesitated to bring up such a sensitive topic, but curiosity had long ago burned the delicacy out of her in situations like this.
“Celestia…what happened to Twilight Sparkle after…that?”
The Princess nodded, as if expecting the question. “I never saw her again afterward. She left the kingdom completely, and she hid her tracks so well that even with all the royal resources, we couldn’t uncover a single lead. Luna and I…we never spoke of the episode again. That day tore a hole in our lives that has never been filled, although sometimes…” She shut her eyes for a few moments, attempting to reconcile the tragedy with the bestial thrill.
Celestia’s voice was contemplative, with an undercurrent of sadness. “After she vanished, I burned all the poison joke in the Everfree Forest. Every leaf and root. Maybe I thought she’d come back if I did that, but…” The Sun Princess’ sigh was unusually weary. “I’m sure you’ve figured this out by now, Mary, but actions have consequences. Mistakes are made, and no matter who is right or wrong, sometimes things can never be the same.“
The Princess gazed at the rising sun outside, unflinching before its dazzling glare. “I’ve gone through the whole process of blame and self-loathing, and if there’s anything I’ve learned from it all, it’s that there’s no sense in seeking out forgiveness. If it comes, it comes. Meanwhile, you live with yourself as best you can. I believe that my dear Twilight will return someday, and when that happens, I will accept any and all condemnation she wishes to damn me with. But until then, I can only be the Sun Princess Celestia, centuries-old habits and all.”
Mary wished that Celestia could hear the longing in her own voice when she said Twilight’s name. The desire for forgiveness wasn’t an object one could pick up and put down at one’s leisure, but that was a conundrum that Mary didn’t think she was equipped to help with. Did ponies ever go to therapy? That felt like an important thing to find out.
Mary’s eyelids drooped as she began to slip away. “Like you said…you can only be you. Wake me up in a few hours, and we’ll go over everything on the way to Kurosawa.”
Celestia went over to the bed, draping a limb around Mary’s blanketed form. “I will. We’ll do whatever we can for Erin. She’s going to be the star of her own show, and each of us will have a part to play: you, myself, Luna, and even Julie. Erin can never be like she was, but at least we can let her live with herself.”
“Sometimes, that’s all you can hope for,” Mary said as she drifted into slumber.
