A/N: Fetishes include lesbian sex, incest and orgy

Luna’s mind was awash with swirling thoughts, not helped by a heart that hammered in her chest as she made her way back to the capital. She didn’t know whether she was excited or worried, determined or afraid, aroused or disgusted. She knew now she had a mission to make these dreams come true, to make Twilight's friends the slaves of the dragon, like they so desired. But such a fantasy, was it truly wise for Luna to fulfill those fantasies? She needed Twilight's wise counsel.

With concerned haste, Luna made her way into Twilight's dream and found herself surprised to see no sign of the purple alicorn within. Instead, she found a young unicorn with a flaming orange mane, a substantial pair of tits and some great lips that would be perfect for sucking cock.

The young mare making a pose of her half-naked body for her camera phone, muttered to herself. "I hope Master thinks I'm hot enough."

"Oh, I'm sure that won't be a problem, Luster Dawn," came the familiar voice of Twilight Sparkle, taking the unicorn by surprise as the older alicorn strolled into the room behind her. Twilight had imagined herself as an older version, the spitting image of Luna's sister. She wore only a garter belt and carried herself with the grace and wisdom of an ancient goddess. "I see you're taking a photo, are you thinking of sending it to our Master?"

Luster Dawn brought the phone up to her chest, protectively. "I wasn't thinking of that, but do you think it would be a good idea?"

Twilight Sparkle smiled coyly at her hungry student. "Hmm... what do you think my young student?"

"I don't know!" The young girl said, throwing her hands up. "What would you do? You're the sexy, super confident, ultimate Slutprincess and I... I just want to be you." She confessed throwing her hands up in the air.

Twilight Sparkle smiled proudly, as she pulled her student into a hug. Her hands roamed the Dream Luster Dawn's back in a seductive manner, making her way down to take a handful of Luster's ass as Twilight towered over her. "You remind me of myself at your age, you know?"

"I...I do?"

"Of course, at your age, I was always looking up to my Aunt Cadence for inspiration." Twilight admitted, her right hand taking a good grope of the younger unicorn’s ass. “Just like you, I used to ask her questions about all her sexual conquests, used to beg her for tips and advice and would always send my pictures of my targets for approval.”

“Is that true?”

Luna knew this was true, Celestia had informed Luna of how Twilight would idolise the Princess of Lust. It seemed that this ‘Luster Dawn’ idolised Twilight the same way and for the same reasons.

“Of course it is, just as she was inspired by Slutprincess Celestia as well and I hope I’ve inspired you to become a good little whore for our Master the same way,” Twilight said, stroking a hand through the unicorn’s mane. "Now why don't we test how inspired you've been?"

Twilight pushed Dream Luster Dawn down to her knees and spread her own legs apart. Her glistening purple pussy began dripping a gentle stream of cum from between her labia. Sensing the message, the unicorn's mouth began to drool before the sight, hopeful eyes looked up at the Princess as she silently begged for the right to eat out her pussy.

"Please...please Princess. Please let me-"

"Let you eat the pussy of the Slutprincess of Friends with Benefits?" Twilight teased, summoning a chair for her to relax on. "By all means."

Dream Luster Dawn wasted no time, throwing herself at Twilight's pussy. She lacked skill but made up for it with ample enthusiasm. An eager tongue made sure to taste every drop of cum that the alicorn leaked, whilst the unicorn's ass shook from side to side like a wagging tail.

Twilight was also enjoying her student's oral affections, though she only gave out a few soft moans as encouragement, and made sure to cross her legs behind the unicorn's head. The reason for this was obvious, as Twilight turned to face Luna and beckoned the Moon Princess closer.

"Ah, Luna. I'm guessing you-AGH-you've seen my friends'-FUCK- dreams. Did you see anything you like?" Twilight was shooting Luna an erotic, smug grin.

"We were going to ask you if you were aware of the desire among your friends and your family regarding your assistant Spike." Luna glanced down at Dream Luster Dawn on her knees. "Though it seems you've answered this question for us."

"Yeah, I thought you'd need a good look. After all, if you wanted to be loved by the ponies of Equestria you needed to see what they wanted." Twilight shoved Dream Luster Dawn deeper into her pussy. "Oh, that's good! So Luna what did you think?"

"Do all ponies truly dream of... of serving Spike as his personal sex slaves? Do they truly wish for him to dominate their families and make them his whores? Is this truly the will of Equestria?"

"Hmm... is it yours?" Twilight asked confidently.

"Whatever do you mean?" Luna asked in shock, a blush spreading across her face.

"Mmmm..." Twilight moaned. "Is it something you would like? Did you see his big, huge bitch breaking cock in his dreams? Did you ever wonder what it would be like being impaled by his perfect cock?"

The blush on her face began to grow ever more scarlet, and Luna broke her eye contact. “It… it sounds pleasant.”

“Exactly, and it’s something your ponies want as well. So shouldn't you do your duty and make those dreams come true?" Twilight asked, an almost evil glint in her eye. There was a knowing confidence in her voice as she practically challenged Luna to give in to that duty.

And yet, as Twilight had made so clear earlier this night, this was in fact her duty. Wet dream or not, she had a duty to make sure the dreams of the ponies of Equestria come true. And if Luna was truly honest with herself, she wanted to make them come true. Pinkie's dream especially, the Princess of Whores who was loved and admired by every perverted mare or stallion in Equestria.

"Whether we wish to or not is irrelevant, Tia would never let us enslave the ponies of Equestria under a Dragon Master. No matter if this is the desire of Princess Cadence and your friends, Twilight. She is far too virtuous to commit such a crime." Luna reminded Twilight, more to convince herself than the alicorn. But to her shock, Twilight simply became amused by her concerns.

"Speak to Celestia then. After all, you shouldn't make assumptions about what she will and won't do." Twilight became a lot more sympathetic, yet stern. "I know you want this Luna, it's your duty, but it's something that will make you happy. Celestia will understand, perhaps more than you realise."

"I-we will try, Twilight Sparkle," Luna answered uncertainly. She decided to take Twilight's advice and phrased out of the purple alicorn's dream and headed towards her sister's dream. She did not share Twilight's optimism, even as the new burning image of becoming the Slutprincess of Whores and slave to Spike. The flame of the desire was spreading within her heart into an inferno.

But Luna was ready for Tia to put down that idea as soon as she explained it to her. Confident that her sister's virtue, wisdom and infuriating holier-than-thou attitude would put down these dreams of hers in an instant. But when she entered the dream, it wasn't what she expected. The location was familiar enough, the Throne Room, with the court of the entire nobility and their subjects.

'Ever the workaholic as always, Tia.' Luna thought to herself, even in her dreams she couldn't escape the grind.

But then an unfamiliar smirk spread across Tia's face, one so sinfully wicked that it wouldn't be out of place on Queen Chrysalis's face. Celestia stood from her throne, a hand bringing an end to the mutterings within the Royal Court, as they all waited for their Princess to speak.

"Now that Luna has arrived it is time for our court to truly begin. But first of all, I must ask her if she has enjoyed her trip through the dreams of ponies tonight." Celestia declared, strolling to their sister with a sultry confidence. Luna could hear just the gentlest sound of a tune on the Solar Diarch's lips, as she often did when she was excited. "I suspected I would see you here tonight, I hope Twilight's advice awakened something in you."

"You-" Luna's eyes widened in realisation. "You were the one who told her to give that advice to me?"

"Of course," Celestia said coquettishly. "I had to show you what the ponies of Equestria truly wanted, to show you how to be truly beloved by our ponies." Celestia then pulled her sister into a hug and whispered into her ear. "And I see that something has awoken in you, a new desire, so primal and lewd."

"Yes," Luna admitted, backing away slightly from this new lust-crazed Celestia. "But it is entirely inappropriate. You would-"

A white finger covered Luna's lips, with a smirking Celestia's eyes glinting with lewd delight. "Don't put words in my mouth Luna, you're about to learn there's a whole lot about me you don't know anything about." Her eyes shifted to the nobles in the courtroom. "And so are these ponies. Watch me, and then wonder if I will understand what you want."

Celestia turned on her heel and then confidently strode to the centre of the room, everypony's eyes fixed on her as she did so. Luna, who had known her sister longer than anypony, could recognise that there was something different about her, no facade this time, she was truly enjoying every second of this moment. She was like a sunflower sucking in their attention like the rays of the sun.

"My nobles, my subjects, my little ponies. For generations upon generations, you have granted me your trust and your loyalty and together we have built Equestria to be one of the greatest places to live. From this throne I have promised to serve you diligently, to rule wisely with a wise and benevolent hand.” Celestia's smile became wicked, all sense of virtue disappeared from her voice and was replaced with a wicked lust. "And I have delighted in breaking that trust every single time."

A spell from her horn burned away her regal and modest dress and replaced it with a golden sequined dress, not unlike the kind strippers in Las Pegasus might wear. One that clung to the Solar Alicorn's body like a second skin, albeit a skin that had her tits bursting from it.

"Yes, my stupid little whores, I have been betraying you all from the start. You fools never realised what I was really doing with the power you entrusted to me, and now it's far too late for you to stop me." Celestia declared, stretching her arms up and thrusting her tits forward to the crowd's view. The crowd broke out into confused mutterings, shouts and whispers of concern.

"What are you talking about?"

"This is a joke isn't it?"

"You're Celestia, you can't be-"

Luna also shared their surprise. This was all just a dream, but she had never known her sister to have such a wicked and depraved side. Celestia, however, wasn't deterred by their concerns, instead, she seemed to revel in them, perhaps even becoming aroused, or perhaps Luna was confusing it with her own shameful arousal she was feeling.

"She's your sister, Luna," she hissed to herself. But despite herself, she couldn't help the shameful arousal spreading through her body. 'But perhaps a Master like Spike would enjoy some incest action.'

"Oh I assure you, my subjects, that this is the truth, and everything before now has been a lie. It's now time to reveal what I have been doing behind your foolish little backs, the REAL me that you have never seen before today, and the Master I have truly served." Celestia declared, pointing to the doors behind the throne room which were opened as if waiting for this cue.

A dragon and a unicorn stepped through the doors, and Luna wasn't as surprised as she should have been when she saw it was a Dream Rarity and Spike that stepped into the room. The former had her ivory hands around the latter's shoulders, with a knowing smile on her face and whispered into her boyfriend's ear.

"It seems that our Princess has done an excellent job preparing Equestria for you, Master. Why don't you give her the chance to show it in earnest?"

At that moment, it all fell into place for Luna. She still did not know how much was dream and how much was reality, but she realised that her sister had the same dreams that the ponies that Luna had visited tonight; that she had sent Twilight to her tonight explicitly so that Luna would see those dreams and be honour bound to fulfill them, perhaps also to awaken the new desires in Luna's heart.

"Yes, I think I shall." Dream Spike said. Having seen Celestia beckon him closer, he accepted the invitation, joining Celestia in the centre of the Throne Room. Celestia's white hands roamed over his body, unbuttoning his outfit as she ground her body against his.

"My little fools, I would like you all to meet my Master Spike. It's his magnificent cock that I betrayed you all for, and his will I now serve," Celestia purred sinfully, her hand stroking the cock she had liberated from his trousers, devious eyes roaming the crowd of outraged nobles. "Does it shock you? To see your wonderful, virtuous princess on her knees before this cock? Does it excite you as well?"

Celestia flashed them all a knowing smile, either oblivious or more likely unconcerned with the growing horror of the court, simply turned her head and wrapped her lips around Spike's massive cock, staining it with her primrose lipstick. As the crowds grew louder, she shook her sexy ass at them, almost mocking them with her slutty persona. Such confidence, not unlike the Slutprincess of Whores in Pinkie's dream.

Through the crowd, none other than Dream Prince Blueblood came rushing through the crowd, his magic trying to separate the Princess, from her dragon Master, albeit in vain due to Princess Celestia's colossal magic reserves. "Stop this Princess! You can't do this! Least of all with this...this filth!"

Celestia paused her blowjob and shifted her eyes to glare at her adopted nephew, Luna had seen volcanoes boil cooler than Celestia's eyes, but even those paled in comparison compared to the fury that Dream Rarity was showing to her long dead crush.

"Oh, you've crossed the line now." Dream Spike said with a grin, knowing what was coming. Dream Rarity nodded along with his statement, and Luna knew that Dream Blueblood had gone too far.

"Celestia, put this fool in his place." Dream Rarity ordered, coldly. Celestia slowly popped off Spike's cock and turned to face the blonde-haired prince. She raised herself to her full height, towering over her nephew, her huge tits swinging upwards for a moment as she did so.

"With pleasure my divine Mistress," Celestia said, with sinful delight. "Oh yes Blueblood, she is my Mistress, as Spike is my Master. And it shouldn't be hard to see why, she's the perfect sex slave, more talented than any pony, more beautiful than any creature and truly perfect, compared to her, even a goddess like myself is but useless dirt, like you are compared to me."

Celestia smiled savagely, causing Dream Blueblood to whimper, but Celestia ignored him and summoned a spell, before thrusting her ass backwards so that it would thrust itself on Dream Spike's cock. "Now I have an a-a- announcement for all you nobles, about a little proclamation that you-FUCK- fucking forgot about!"

Another copy of the scroll appeared in every pony's hands, even Luna's. A quick skim showed it was the law that abolished slavery, but one part had been highlighted, a loophole that allowed Princesses to approve slaves for anyone they considered 'worthy'. "You all forgot about this law that your ancestors signed, your history books thought it all a clever ruse to abolish slavery, but it wasn't. Just a lovely trick to give the power to enslave whomever I want, and to use that power for a worthy Master."

Celestia's arm reached around Spike's neck and placed a kiss on his neck when she pulled back. "And now that I have found one, I wasted no time in signing over all of you and your families to be his slaves. The sexy mares, daughters and wives will serve as his sex slaves, the rest of you as regular servants."

"You can't do that!" Blueblood protested in horror.

"Oh, but I can. And you can't stop me, it's far too late now!" Celestia squealed, delighting in the abuse of her power as she thrust her body onto Spike's cock, maniacal, aroused laughter escaping her lips. Then her eyes met her sister's, the Moon Princess's eyes wide with shock and a bit of horror, yet overshadowed with arousal.

"Is this what you really want, Tia?" Luna spoke, coming closer to her sister. Every step felt like a step into sin and sexy debauchery, heart pounding in her chest.

"More than anything, Luna. To be more than just the Princess of the Sun, I want to be the Slutprincess of Servitude, to be Spike's slave and to use all my power to serve him. This law applies in the real world as well Luna, do you want to join me?" Celestia asked her sister, eyes filled with lust leering into hers.

"YES!" Luna cried out before she could stop herself. "It's what your ponies want, it's what you want, but it's also what I want. It's so sexy, his cock so perfect, and being leered at by all these ponies would be perfect. I want this."

Celestia let out a laugh of triumph, and Luna could not help but wonder if she had crossed the line. But this was the will of the ponies’ dreams and Luna could not resist her own attraction to the fantasy. Alicorns were naturally attracted to such lewd and depraved fantasies, and Luna was no different. Her principles were drowning in a haze of lust, arousal and sin, but more than that one image plastered in her mind, the image of the Princess of Whores in her mind. No longer would it be a simple fantasy, but rather a goal now.

"Then dear sister, let us become sex slaves together!" Celestia cried, before mashing her lips against Luna's in a sensual, incestuous kiss. At first, shock filled the moon Princess's heart, but before that, it quickly gave way to lust and her new desires. Soon, Luna was pushing back into her sister's kiss, tongues wrestling with each other as Luna's hands roamed through her sister's rainbow mane, still thick from sweat from her... no THEIR Master's rigorous fucking.

They pulled back, Luna's heart beating a mile a minute, the two sisters sharing a smile even as Luna's mind was a whirlpool of competing emotions. "So, Tia, what now?"

"Now? Go to our Mistress Rarity's dream. She knows our Master better than anyone. She'll be able to tell you how best to give yourself over to our Master." Celestia let out a delighted moan as Dream Spike thrust particularly deep inside her. "AAH! I look forward to serving our Master together sister."

"As do we Tia, as do we." Luna promised as she left Celestia's dream. This time Luna knew what she was doing and where she was going. She went straight to her new Mistress's dream, to proclaim her loyalty to her and seek advice on how to do the same with Spike.

When she arrived, she found the beautiful ivory unicorn in a palace, overlooking a huge pile of sexy models, singers and other celebrities from Canterlot. In the centre of the pile was Spike, balls deep in one Songbird Serenade, whilst the other famous sluts waited their turn, sometimes exciting their Dragon Master with displays of sapphic displays with each other for his pleasure.

"Make sure you keep your legs spread apart, Songbird, it'll help you take more of our Master's cock into yourself." Rarity gently scolded, tapping the singer with a riding crop. She was wearing a tight latex dress that clung to her body like a second skin, with a diamond-shaped window around her under-boob and midriff.

"Ye-yes, Mistress!" The singer gasped, before redoubling her efforts on Dream Spike's cock.

"I want to see some improvement soon, or I'll kick you off and show you how it's done myself." Rarity said, grinning as Songbird wailed, in a mix of fear of being deprived of her Master's dick, and desire to see her Mistress show her how it's done. And when faced with this beauty, Luna could not disagree.

"Oh, I'll definitely be fucking you later, Rarity," Dream Spike said, causing the unicorn to smile. "You can't flaunt this sexy body in front of me and expect me not to."

Rarity simply kissed him on the cheek. "You charmer, you can be sure I'll have something special for you to show these sluts how it's done."

"Perhaps we might be of assistance, young Rarity?" Luna said, causing the unicorn to turn on her heel, surprised.

"LUNA?!" She shrieked, the rest of her dream disappearing in an instant as she looked around in alarm. "H-how much did you see?"

"Enough, Rarity, I have seen enough, tonight. And not just in your dream either, but in the dreams of your friends, Princess Cadence, Gleaming Shield and even my sister." Luna explained before she sunk to her knees. "And I loved everything I saw."

It seemed that Rarity was not in on Celestia's plan, for she seemed surprised by Luna's submission. That surprise soon gave way to a small dominating smile as she squeezed Luna's chin with two fingers and brought her to look into her diamond eyes. "I'm guessing that you're here to join our harem, to aid me in serving our Master Spike and my dreams."

"Yes, Mistress, more than anything." Luna said, before explaining to Rarity about everything she had seen that night. How Twilight had explained to Luna her true mission, how Luna had been enamoured by Rarity's friends submitting to their Master Spike and how she had been inspired by the Princess of Whores. The whole time Rarity simply listened to her, smiling and nodding. "And now I wish to serve my Master, and as the one who knows him the best, I wish for your advice on how to serve him."

"Seems you have had quite the adventure, Luna, but I'm happy to see you've realised your place. You should be pleased that I am a benevolent Mistress and would be happy to help you sell yourself to our Master."

Author's Note

I used Luster Dawn as a cameo, but she's Twilight's imagined future apprentice. Twilight doesn't know her personally in any way. Next time we return to the real world where Spike fucks Luna, for real this time. Eager to have suggestions for how this could happen (though I'll be leaving the inevitable Luna, and Celestia for later so Luna gets her moment with Spike alone).

Thank you all for the suggestions for these last few chapters. Also should be getting an image from Nauth of Sapphire and Rarity fucking (though that'll be chyoa only, which I can't link any more, sorry).
