For the second day in a row, a loud knocking woke Celestia up. The sight of a guard with the red ribbon of a scroll gripped between his teeth greeted her. She smiled down at him before using her magic to gently pull the scroll from his jaw. The familiar sensation of magic emanated from the scroll as Celestia pulled the bow-tied ribbon undone and unfurled the scroll, levitating it mere inches in front of her face. It’s blank? Upon further inspection, Celestia noticed that the scroll had an enchantment on it, one that only she could break. Clever colt, Celestia thought. With a wave of her horn, she broke the enchantment and the text became visible.

“Your highness, Princess Celestia, from what I can gather, Nightmare Moon is a creation of Luna’s own mind; that is to say, she does not exist in our physical world. Regardless of that fact, it is still possible for her to interact with the world around her and be seen by ponies other than Luna. She does this by draining a small amount of Luna’s energy. She is nowhere near as powerful as she was a millennia ago, so seek comfort in that fact. If Luna can exhaust what energy Nightmare Moon has absorbed from her, through any means possible, such as physical activity, keeping her awake for long periods of time, or what have you, she and Nightmare will become one, so to speak. Luna will not become Nightmare Moon as a result of this. There is no potion or remedy that can act as a cure; Luna will need to do this by herself. For all of our sakes, I wish her the best of luck, because she certainly will need it.

~ Sincerely, Inky”

While reading through the letter, Celestia noted that the guard was eyeing her. “Is there something on my face?” she asked, genuinely confused.

“With all due respect, your majesty… it is your face that is worrying me.” Unbeknownst to her royal highness, she looked terrible. Dark bags underneath her eyes sharply clashed against her alabaster coat, making it look as if she hadn’t slept in weeks.

“I have had a very long night, please excuse my unkempt appearance.” She gave a small, weak smile.

“Think nothing of it, your majesty. I just saw it as appropriate to tell you before you’ve left your quarters.” He smiled back, exposing a few gaps where teeth should be.

“Thank you.” Celestia dismissed the guard and returned to her room. ”If Luna can exhaust what energy Nightmare Moon has absorbed from her, she and Nightmare will become one, so to speak.” Celestia repeated out loud. What a cryptic way to word it, she thought. “What does that even mean?”

Celestia started the day with a shower, as she did every day. The alabaster mare always used this free time to do critical thinking, and that morning was no exception. It would come as a shock to most ponies that the princess of the Sun, and by association the day, was, in fact, not a morning pony. She never liked waking up and facing the world around her; leading an entire nation is very hard work.

While lathering her body in expensive luxury soaps, she repeated the direction over in her mind, having long since memorized it. The soap in her coat seemed to melt off as she stepped back into the downpour of the shower, eliciting a sigh from the regent of the Sun. Exhaust her energy… physical activity… keeping her awake… Hooves absentmindedly ran through her soaked mane, covering it in thick soap. Celestia’s face reddened in a blush as her mind came to a conclusion.

“Oh, me… Luna will not be happy.” A sigh followed as Celestia stepped back into the water with a smirk. An incredible sense of relief flowed over her before bursting into laughter, coming to an abrupt halt when she choked on the cascade of water. Such a huge problem, yet with a solution so simple - something carnal, primal, something that ponies were created to do – it made her lose her regal self in a moment of glee. “Well, I suppose it would do Luna some good to get laid.”

…

When the audible ping of magic woke Luna up, she had to fight to escape from Nightmare’s bear hug of a grip. Upon widening her eyes to their zenith, she looked up, cross-eyed, and saw her horn half-covered in dried saliva; the other half was still in the mouth of the larger mare atop her. Her muzzle parted to let out a gasp of shock as she pressed her hooves against Nightmare’s chest, slowly pushing her body backwards, all the while trying her best to ignore the incredible, almost intoxicating, sensation emanating outwards from her horn, moving down her body like a hot, pulsing wave of pleasurable energy.

Nightmare seemed to feel Luna’s struggle, slowly inching her horn out from the warm and wet mouth, though never quite getting her appendage all the way out. As Nightmare sucked harder on the solid, nerve-filled bone, wrapping her tongue around the swirled groove and tracing it up and down, sending shivers throughout Luna’s body, causing the princess to writhe and twitch in pleasure, her dark lips curved upwards ever so slightly into a grin; completely unknown to Luna, Nightmare Moon was awake. She hadn’t gone to sleep – she had been awake all night, playing with the regent of the night’s horn, forcing her unconscious body into orgasm many times, as was her habit, and, not-so-secretly, her fetish. Surely this will be a suitable apology for screwing up her precious painting, Nightmare thought without fear of Luna hearing her over her own soft moaning the dark alicorn continued the powerful swirling of her tongue. This energy shall suffice for at least another month!

Of course, Luna had known of Nightmare Moon’s habit, though her still half-asleep brain couldn’t recall anything at that moment, nor did she remember prior to going to sleep in the early morning. In hindsight, she should’ve seen it coming. Not that a free, albeit spontaneous, hornjob was entirely unwelcome... all she knew in that moment was that she was getting sucked off by Nightmare Moon and was unable to resist, but why would she want to? Amidst her ancient thoughform’s flurry of slurps and licks and her own soft moaning, Luna felt a kind of pressure building up near her groin, realizing it as a sign that she was rapidly nearing climax. The princess’ soft moaning grew louder, encouraging Nightmare Moon to reach her hoof over Luna’s belly, down to her dampened nethers, sliding her hoof against the wet fur against her thighs, firmly grinding her moistened hoof against Luna’s outer lips. Cheeks ablaze in a crimson blush, Luna inched closer to Nightmare Moon, their bellies now touching as she moaned her name with a smile on her face, “Oh, Moony…”

The dark alicorn could feel the sparks of magic seeping out from the tip of her horn; the taste was extremely metallic, yet sweet in an odd way. It made Nightmare Moon’s tongue tingle as her deft muscle reached the metal clasp and circled around it, forcing the red gem in the center to light up, vibrating slightly against Luna’s horn. The princess was now panting, open-mouthed, gasping for air as her chest rose and fell. Nightmare knew she was close as the tangy taste in her mouth intensified greatly, a sign to redouble her tongue’s rapid swirling and lapping, moving the edge of her drenched hoof back and forth against the princess’ soft, pliable sex. Luna’s back arched, her head pulled backwards, and her cerulean eyes clasped shut as she came with a scream, alerting the guards outside her quarters.

…

The two Dark Guards looked to each other, smirked, nodded, and then adjusted themselves against the door, knowing only a part of what was transpiring within the princess’ quarters. Lucky for them that their helmets concealed their blush. As the unicorn fought for dominance with his partner to keep his head up against the peephole, a bridge of golden magic connected his horn to the door, and then sent him flying backwards into the air a moment later. His companion, a pegasi, flew to catch him before he went through the window, managing to save him from plummeting a few thousand feet to his doom just a few feet before colliding with the ornate glass. “Not a single word of this to the Captain.” The unicorn hissed. The pegasi nodded with a smirk, then moved back to his post beside the door.

…

Nightmare Moon’s eyes narrowed at the sound of a boom outside. Stupid guards… she thought, swallowing the sparks of pure, warm magic seeping out from Luna’s horn without falter, having had her mouth re-learned well from Luna’s previous myriad of horn ejaculations throughout the day whilst she slept.

The dark alicorn let go of her powerful grip on the hypnagogic princess as she felt her uncontrollably twitching and letting out pained groans, a result of her overly sensitive parts, the pleasure so great that it was beginning to grow unpleasant. Nightmare allowed Luna to fall to the soft bed beneath her, eyes still closed as she listened to the sound of her heart beating away rapidly in her own chest, lounging through the afterglow. Nightmare shifted onto her side, content with a job very well done. She brought her dark hoof up to her mouth, the wetness of it glistening in the darkness. Her tongue met her hoof as she licked it clean, enjoying the flavor of the princess still fresh on it. The dark alicorn shifted, resting her hooves over Luna’s body, gently hugging the princess as the two mares laid there, spooning.

Hours later, when the princess woke up alone, she found her sheets dampened in a mixture of sweat and cum. Not an entirely unpleasant smell, but one that needed to be cleaned up nonetheless. Later… much later, after a shower.

…

Luna groaned loudly as she walked out of the steam filled bathroom, shivering at the coolness of her room. After kicking a log into her ever-lit fireplace, she entered her room, cocked her neck to the side and found the scroll on her desk that had been waiting for her for a little over an hour now.

“Dearest Luna, I have some, dare I say, interesting news for you. The pony that I talked with (a kind colt who goes by the name of Inky) two days ago has indirectly told me what you must do. He says that Nightmare Moon has been using your own energy as sustenance, taking very small amounts from you without your knowledge nor consent. In doing so, she maintains a physical body that is selectively active. Inky has said that you must drain the energy from her, and she will be no more. As a result of this, her being will become part of you, thus empowering you somewhat. Fear not, you will not be controlled by her influence in doing so.

Now, as for the actual process of exhausting her… you may not like it, or perhaps you shall, I don’t know. Forget the formalities, you’re my sister, and nopony else will see this. You must have sex with Nightmare Moon. Anyways, when was the last time that you’ve gotten some flank? Loosen up some and try to enjoy it. Have fun, my dear sister, and best of luck!

~ Love, Celestia”

Did her eyes fail her? Had she really just read that? Were those actually words written by her sister on that scroll? Surely it had been a mistake, Celestia was just pulling one of her pranks again. When you’ve been around for as long as she has, you need to find ways to keep yourself amused. But this… this was going too far. Yet, the wording... it seemed so foalish, unlike Celestia’s normal self. Exactly how she acted when pranking. Luna knew her sister well, better than any other pony as a matter of fact, and she knew that her sister, of all ponies, would not use something like that to her own amusement; even if it was rather humorous.

Luna looked back to the scroll, and read it over again. She had missed something at the very bottom of the page, “P.S. Don’t forget to work that clit!“ Underneath the post-scriptural comment, there was a small, crudely drawn cluster of hearts.

“Damn it all.” The paper crackled as the fireplace incinerated it.

Luna walked from her bedroom to the small kitchen and quickly whipped up a steaming mug of coffee, adding an ample amount of milk and sugar to it before returning to her room, slowly taking one step at a time while holding the mug on a plate skillfully balanced on the flat her back. Her bed was empty, save for the warm, and still slightly dampened, divot where Nightmare had been laying.

Taking it as time to get some private thinking done, Luna sat down at her desk, where she got most of her important thinking done. How am I supposed to do this? I can’t rape her; that’s just not right. She clearly still loves me, as evident from sucking me off, and even though she is an evil mare, she means good in her own weird way. If I am lucky she will consent and we can get this over with. It’s not like we haven’t been intimate with one another before. Luna took a moment to sigh into the mug of steaming coffee before bringing it to her lips and gulping down a couple mouthfuls of the heavenly, energy-infused dark liquid.

I digress. I suppose it’s more like masturbation than sex, now that I think about it. It has been a long while since I have been intimate with anypony else, as ‘Tia had so bluntly pointed out. Another couple sips graced her lips to help the princess clear her head.

If anypony deserves sex, it is she. A thousand years alone with only your hoof to relieve yourself, surrounded by nothing but moon rocks must’ve been hell for her libido. I am glad I wasn’t aware of anything during those years. It’ll be like a farewell gift – the last thing she will feel is the most incredible climax of her life. And then she will be no more. Anyways, I’ve still got to return the favor… Luna shuddered in remembrance of Nightmare’s earlier display of oral finesse, nearly spilling the mug that she held firmly in her fetlock.

The goddess of the moon exhaled deeply. Then it is settled, I shall seduce Nightmare Moon! I just need to keep my motives a secret. Somehow. This is going to prove difficult.” The empty mug slammed against the desk as she swallowed the last drop of coffee, shaking her head at the disgusting mouthful of sugar that came with it. With her mind reinvigorated and body peaking with energy, Luna returned to her studies.

…

Nightmare Moon left Luna alone for the night, allowing the azure princess to focus on her books. Silence reigned the entire time from opening the cover to closing the binding shut. “It’s almost too quiet,” Luna said in a whisper before she turned around, the lack of a certain black pony striking her as peculiar. “Whatever.” She placed the book on top of the ‘To be returned’ pile on the corner of her desk and turned around to began trotting back towards her bed, then spun turned back around as she sensed the familiar, unmistakable residual magical energy of a teleportation spell behind her.

A fairly small book rested on her desk, still shining with her sister’s golden magic. Luna reached out for the scroll next to it.

“Dearest Luna, I would advise you to brush up on your, shall I say, technique before-hoof. Things have changed a lot in one thousand years. I’ll write to you again at dusk. I also realize that you probably think that I am kidding, but you must admit, this is a rather humorous predicament. What would you do if you were in my hoofshoes? I’m sorry, truly, but I couldn’t resist earlier. It was childish of me and I apologize.

~ Love, Celestia.”

“It couldn’t hurt.” Apprehensively, Luna returned to her bed and opened the cover, which depicted two androgynous ponies sharing a passionate kiss. It didn’t take long to brush through, as it was mostly pictures with brief sentences beneath; it was an interesting stack of paper regardless of the fact that it covered nothing that Luna hadn’t seen, experienced, or heard of before. In short, it was a huge waste of time.

As a princess, it was virtually impossible to maintain a relationship and extremely difficult to get out of the castle for enough time to find somepony to have some quick adult fun with. Even if either of the two princesses could secure some off time, they would have to disguise themselves, completely unbeknownst to the pony of their choosing. It was always exhilarating, to be a deity thought untouchable by mortal hooves, and yet the two mares had done it many, many times throughout their long lives.

It had hurt to know that she would probably never be able to find a soul mate to spend eternity with, but as time passed Luna accepted her immortality’s cruel curse and made due with it. An endless string of anonymous one-night stands wasn’t the worst thing in the world.

Luna tossed the flimsy paperback book onto the desk, skillfully landing it on top of the already impressive pile of finished volumes. She gave herself a mental pat on the back and moved the pile of pillows to accommodate the painful kink in her neck from arching her head up to read. Somewhat relaxed, she thought back to her last time with another pony aside from Nightmare.

Luna had always preferred mares to stallions; she tended to stick to what she knew best. The princess always had an affinity for younger ponies too – theoretically, of course. The only other ponies that even came close to Luna’s age were Celestia and Discord. One of which was impossible to hook up with (not to mention absolutely revolting) and the other was… her sister. Incest is generally frowned upon in Equestrian society. Not that anypony had to know what the regal sisters did in their private time, but Luna did not want to risk it. That is not to say that they hadn’t played with each other before, however. And damn, was Celestia good, Luna recalled. Eternity is plenty of time to make one into a prodigy in the bedroom.

She was a cute mare in her early twenties, full of youthful enthusiasm and life. Her name had long since faded from Luna’s memory, but she could still remember almost exactly what she looked like. What she felt like. What she tasted like.

Luna’s hoof unconsciously began sliding down to her inner thigh as she let out a sharp breath. The dream guardian soon found her hoof mere inches above her crotch, just under her navel.

She was a well-toned, cream-colored earth pony with a long, jet-black mane that felt like soft velvet. Clearly she wasn’t an athlete, but not a sloth either. Lacking in either sensitive appendages, she made up for it in an impressive amount of stamina and flexibility, as most earth ponies did.

“And that tongue, by the gods. That incredible tongue.” Luna bit her lower lip as she felt a pleasant, needing heat begin to build up in her nethers.

Luna had disguised herself as a pegasus, using magic to make her horn both invisible and intangible. Instead of her normal dark blue coat, it too was changed to a brighter shade of sky blue that matched her altered, bright blue eyes. Her mane was tied behind her neck in a short ponytail, hanging freely and bouncing about with every step that she took. The cutie mark she thought of was one of a telescope with a cluster of three stars around it. With the conjured glasses and somewhat adorkable appearance, she had become an astronomer.

The corner of her hoof brushed across the exposed nub of sensitive flesh at the topmost part of her moist sex, coaxing a high-pitched squeak out of the lunar princess.

Luna recalled every enticing squeak, every sensual lick, and every playful nibble of the encounter. The incognito princess did not let such generosity go unnoticed. From the all-mares club, affectionately known as ‘Melody's Midnight Mares’, Luna brought her slightly inebriated self and buzzed companion to a hotel, laughing and giggling the whole way down the paved streets. Upon opening the large doors, ‘Star Striker’ screamed to the sleeping receptionist, “Deluxe suite, just for the night. Fifty bits, correct?” ‘Star’ tossed over five platinum bits before the colt could respond and grabbed the key from his blue magical aura. With the key ring in her mouth, she began eagerly skipping down the long hallways with the earth mare following close behind. She was surprised to see that ‘Star’ carried around such a large amount of bits, but didn’t feel the need to question it.

When the door slammed shut, the mare wrapped her hooves around Luna’s shoulders, standing upright on her hind legs, bringing the two mares close together in a loving embrace. Their lips locked as their tongues danced about in each other’s mouths, sharing themselves with one another. Luna quickly made her way down the mare, kissing, licking, and nibbling flesh as she went, leaving behind a trail of damp and darkened fur.

Slowly, they began moving towards the large bed, where Luna was finally able to bring her anxious tongue up across the mare’s sensitive pink feminine lips; the earth mare wrapped her hind legs behind the princess’ neck, forcing her muzzle against her soaked mound. A smile crept its way across Luna’s visage as she went to work, skillfully trailing her tongue across the other mare’s wet slit, flicking her tongue against her pink, fleshy pearl. The mare underneath her moaned and giggled in approval, soaking Luna’s muzzle in her fluids.

The Moon goddess’ inner thighs were already soaked with her arousal as she brought her second hoof down to her velvety folds. Another squeak escaped her as she continued her rubbing with both fetlocks, effectively doubling her pleasure – and fun.

Her wings stood fully erect as she continued using her deft tongue on the awestruck mare underneath her, still writhing in ecstasy. The earth mare was just barely able to reach the long, sensitive primary feathers with her mouth. Star Striker, or so the earth pony thought her name was, let out a giggle-squeak as she momentarily stopped her gentle assault on the mare’s nether lips. The mare let go of her tight hold around the princess’ neck and repositioned herself to preen those large, bright feathers. “R- right there, ah!” ‘Star’ closed her eyes as she cried out in bliss, biting down hard on her hoof in a futile attempt to mute her screaming.

Breathing grew rapid and intense as Luna sucked in deep breaths of air through her mouth, nearing her orgasm. Her hooves pressed firmly against her drenched folds as a familiar pressure built up in her groin. The corner of her hoof dug in and upwards against her crevice to tease against her sensitive walls, eliciting a shriek of joy from the mare.

Their sexes met each other in a wet mass, lovingly grinding against one another in search of pure, carnal release. ‘Star’ held the other mare’s hind leg against her shoulder, using it as leverage to pump and thrust against her. As a princess, a figure of authority and power, Luna lost herself in the feeling of complete domination over the mare, further enhancing her enjoyment. The burning fire of lust slowly built up inside of the two mares, eager to be released at any moment. In one final thrust, the disguised princess unleashed the fire held deep within them as they screamed and twitched in explosive climax.

Luna’s mind turned to mush as she reached her peak, soaking her hooves in sticky fluids as pleasure radiated outwards from her groin and up her spine to every nerve in her being. Her screaming seemed as if it would go on forever until she ran out of breath, letting out tiny squeaks as she writhed and twitched in post-orgasmic bliss. Out of breath and exhausted, Luna took a deep inhale and leaned backwards into the plush mattress. Her body went numb as the wonderful sensation coming from her aching, sated sex slowly began to fade.

The satisfied and worn out goddess rolled over and collapsed in need of a rest, relaxing and soaking in the sensuous afterglow. Her mind wandered as she waned in and out of lucidity, having difficulties maintaining the focus needed to realize she was asleep. She eventually conceded to a black, dreamless, and rejuvenating sleep.
