A few nights passed after Celestia’s enslavement, though this was completely unknown to the other Princess of Equestria. A still, calm night had descended over Equestria and it was Luna's time to rule over the ponies. Or at least, rule over those who were awake, which, at this time of night was very few. She stood over the balcony of the palace, Canterlot City sprawled out below her. The breeze of the night brought a small chill to the Princess of the Night’s fur, not helped by the rather skimpy dress she wore.

The feelings of melancholy were nothing new to her. In fact, she suspected that all of Equestria was aware of her feelings on the matter, given how well-known the Legend of Nightmare Moon was. However, as one old and still bitter part of her noted, that didn’t change as much as she hoped. Ponies still slept through the night as she watched over, and Equestria still had little need of her.

She knew these thoughts led to a dark place, so she tried to shake them out of her head but she couldn’t help herself. But there was something else. Luna couldn’t put her finger on it, but something had changed in Equestria. That was something Luna could sense even in the short time she had returned.

It was in little ways. Luna knew her sister was keeping secrets from her, she knew something in the Council of Equestria was amis, she had noticed that her Lunar Guard had been reduced to a ceremonial role while the Solar Guard took up their role.

And then there was the erotic stuff. Luna had been surprised to see the direction Canterlot had taken in her absence. Surprised but not disappointed. After all, even if she could hide it better than Cadence, Luna, like any alicorn, was just as much a horny slut as the rest of them. But Luna didn’t expect Celestia to be quite as blatant as she was.

Things had changed in Equestria, and Luna wasn’t sure what she should do.

"Lonely night, Luna?" Twilight asked, standing the door of the balcony. She had a look of concern on her face, as one would expect from the Princess of Friendship, though she still held that fire of lust that Celestia had recruited her for.

Her outfit was even lewder than the guards, something that definitely drew Luna’s gaze more than she’d like to admit. Barely a strap of leather covered her private parts in a sling swimsuit that accentuated more than it concealed. Despite herself, Luna had a fantasy of ripping that bikini apart and fingering her right there for all of Canterlot to see, waking the sleeping ponies with Twilight’s screams.

Luna shook the invasive thoughts from her head and tried to plaster a simple, chaste smile onto her face. “Twilight Sparkle, tis a little melancholy we admit.”

“Want to talk about it?” She asked.

Luna chewed the back of her cheek. “The thoughts are reminiscent of… an old Nightmare. We… we shouldn’t be considering these thoughts, not when it once led to our past fall.”

“Luna, talking about these issues won’t bring Nightmare Moon back. It might even help avoid that. Processing your feelings could be healthy, you know?" Twilight said, her words containing too much wisdom for Luna to ignore.

“I feel that Tia is keeping a secret from me, that she’s been trying to limit our influence in Equestria even after we returned. That she’s planning something that she doesn’t share with us.” Luna confessed, resting her hands on the balcony.

Twilight took a while to consider her response. She was probably the pony who knew Celestia the second best, idolizing her almost as much as she did Cadence. "I think Celestia has gotten a bit used to ruling Equestria these last one thousand years. I suspect she’s struggling to learn to share the throne with you again.”

There was some truth in those words, but it didn’t really reassure Luna. “We must confess, Twilight Sparkle, tis a little discouraging. Little seems to have changed since a thousand moons ago, ponies still respect my sister over myself, and my efforts go unappreciated.”

Twilight has noticed Luna slip from using the Royal ‘We’ with concern. She walked up to Luna and wrapped her hand around hers. She also pressed her body against Luna’s in a way that was probably supposed to be reassuring, but Luna was acutely aware of Twilight’s bosom pressing into her arm, the one she had personally enhanced herself. Celestia really did have a way of choosing them, didn’t she?

“Perhaps, if you’re feeling unappreciated, Luna, you should change your approach then. Be proactive in proving that you’re a Princess as great as Celestia, rather than moping about your feelings.” Twilight suggested, a reassuring smile on her face, though Luna thought she noticed a wicked gleam hidden in her eyes.

“A fair-minded suggestion, Twilight Sparkle. But, we worry that we will not have the time with our duties patrolling the realms of dreams.” Luna admitted, but she did consider Twilight’s suggestion. “It does seem like a wise idea, but most ponies wouldn’t appreciate it, they’d be lost in slumber.”

Twilight tapped her finger on her chin, pondering that little stumbling block for a minute. “I have an idea.”

Twilight’s smile still held the facsimile of a genuine comforting smile, but a certain slyness crept onto its edges. Some wicked fantasy must have crept into Twilight’s head. It wasn’t surprising to Luna at all, they were both alicorns after all. Such a thought often wafted through Luna’s head at the most inopportune moments.

“By all means, Twilight Sparkle.”

“You’re the Princess of Dreams, Luna, but so far you’ve only settled for stopping ponies from having Nightmares.” Twilight’s smile got coy, and though Luna didn’t know it, she had just activated the Root of Loyalty. “As the Princess of the Night, it’s your duty to make sure dreams come true, not just stop nightmares."

Twilight was delighted as Luna stood straight, her face now filled with new resolve and determination. Hope flashed across her eyes at the prospect before her. "You make an excellent suggestion, Twilight Sparkle. From this moment forward I, Princess Luna of the Moon and Night, will make sure to make the dreams of the ponies of Equestria a reality." An excited smile spread across her face. "And we'll make sure all ponies know exactly who to thank for it shall we?"

"Sounds like you have a plan now," Twilight said, beaming. "But, it is also your duty to make sure the wet dreams come true as well. In fact, those are probably the most important."

"Yes, yes, of course, Twilight Sparkle," Luna said, nodding her head gracefully. "There is much wisdom in your idea."

"You're welcome, Princess Luna." Twilight chirped, her wings fluttering like a bird in excitement. "Could I also suggest that you start in Ponyville and the Crystal Empire? I also have a few friends in Canterlot who would welcome such a visit, if you would be so kind."

"Of course, Twilight Sparkle. After you helped us, we would be happy to." Luna said, gracefully bowing her head. After Twilight had left her with a list of suggestions, Luna entered the dream realm with newfound enthusiasm. Doors presented themselves before her, entryways into the dreams of the ponies of Equestria.

Here, Luna clenched her fists with newfound enthusiasm and said to herself: "Look out Equestria, your Princess is coming and soon your dreams will be fantasies no longer."

Meanwhile, Twilight was making her way to Celestia's bedroom. There was a smug smile on her face, a spring to her step, and she felt a sense of pride better than acing a hundred tests. When she arrived, she found Celestia lying across her bed, like a model from a pin-up poster. She was toying with a leash in her hands and had a strap-on shaped after their Master's dick.

"Your plan worked perfectly, Celestia," Twilight said, feeling a rush of pride as Celestia let out an aroused sigh. With her magic, she strapped her leash around Twilight's neck and yanked the young student towards her.

"As I expected. Poor little Lulu has always been so dreadfully insecure about what other ponies thought of her." Celestia got up and lined up the strap-on behind Twilight's pussy, ready to fuck her in her Master's name. "You did an excellent job, my student. You have become an amoral little slut, haven't you? You've been raised well."

She thrust into Twilight, revelling in the power that she had now, and Twilight was eager to spread her legs for her Princess. "Yes, Princess! Yes! Fuck me, like the slut I am! I look up to you! You, Cadence and my Mom! You're my idols! Amoral sluts like you are my heroes!"

Celestia smirked, as she thrust deeper into Twilight, approaching full hilt. She took her time, however, teasing Twilight with every inch she thrust into her. "Fuck me well, Twilight, and I'll do the same to you. Let us fuck each other into an early sleep tonight and give lovely Luna some wonderful wet dreams to spy on."

Author's Note

So it is no surprise that Luna won, that was the most one-sided vote in this story so far, and it is likely going to remain that way for the rest of the story. Thanks to all the wonderful suggestions you lot have given me I was able to get this chapter out relatively quickly, and it gave me an idea. Next chapter Luna will be visiting the dreams of the harem, but would you guys like to vote on which dreams she visits?

I've made a poll, and you can choose as many options as you want. And we'll see who reaches the top, so feel free to vote for your favourite harem members. This is more of a suggestion than a strict vote though, so if I have a good idea for a character I might add them regardless, and if I can't make it work then vice versa.

Characters are in order of addition to the harem, if I forgot a character remind me in the comments: https://strawpoll.com/eNg69xPr4nA
