Following her ponynapping at the vile hooves of the Changelings, Princess Luna really can't get something off of her mind.

Following her ponynapping at the vile hooves of Queen Chrysalis's Changeling swarm, Princess Luna can't stop thinking about what could have happened if she and the other rulers of Equestria had not been rescued? Not only that but what would become of their great nation should such a dire situation ever befall them again? To the mighty princess of the night, there seems to be only one answer to these questions. But fortunately for Equestria, she has also come up with a solution to the problem. A solution that may involve a certain amount of commitment, sacrifice, a specifically handsome, bat pony stallion, and one great night of pleasure. All to ensure Equestria's future, of course.

Remember, it's all for Equestria!

Remember, it's all for Equestria!

Princess Luna sat at the head of the long breakfast table, within the great dining hall of Canterlot castle. Stretching out before her a whole slew of various pastries, cereals, and other foods had been set up by the castle's staff. All courtesy of the head chef, no doubt made in an effort to show her just how much she and her sister were appreciated.

Regardless of the slaved-over commodores, however, Luna, as always, had chosen something simple to eat before retiring to her bed chambers for the day. Her horn glowed with a twinkling blue aura as she nonchalantly twirled a spoon through a half-empty bowl of oat cereal, once in a while levitating a mouth full of the milky mixture to her mouth and chewing it half-heartedly.

It wasn't that she didn't appreciate the amount of effort that was put into her food every morning, but right now her attention was more focused on something else that sat before her on the dining table, specifically the day's newspaper.

"Princesses Ponynapped!"

"Shocking details are being learned about the ponynapping attempt on out great rulers Princess Celestia and Princess Luna, as well as many other important Equestria figures, by ruthless Changeling forces. This fact, coupled with the attempted invasion by the Changeling queen only a few years ago, has led many to speculate just how safe we and our beloved Princesses really are?"

Luna could not pull her eyes away from the page's title or what followed, and as her eyes slowly moved from side to side and her gaze passed down to the bottom of the page, she slowly stopped chewing her cereal. She didn't like to think about the ordeal she'd been subjected to only a few days ago, specifically her ponynapping at the vile hooves of Queen Chrysalis and her Changeling hordes. Sure, it had all worked out in the end thanks to Twilight's new student and her rather unlikely band of heroes, but once again the solution had not been down to her, her sister, or any Equestrian royalty!

Steadily, Luna moved to take another mouthful of cereal, caring little of the milk that dribbled from the levitating spoon as she thought about what could have happened if Starlight had not found a way to overcome the Changeling queen. She couldn't help but imagine the country would have been thrown into utter chaos without her or the other royals, and that was before considering what the Changelings that had replaced them all may have done in their absence. She really didn't want to think about that, nor recall how it had felt to be locked away in the vile Changeling hive, cocooned and desperately trying to reach out in her dreams to anypony that may be able to help.

Her mind went to work on the idea nevertheless of all the royals being ponynapped again, as such a thing was too dangerous to be left unconsidered after all. Slowly, Luna’s chewing resumed and then she finally came to one, sole conclusion: she could not allow for anything like that to happen again. She could see it now, that the entire infrastructure of the country was currently weak and utterly flawed. She felt like an utter fool for allowing herself to be taken so easily, and couldn't help but see the many issues in the fact that nopony that was supposed to protect her, or any of the other princesses for that matter, had been able to do so. Their Royal Guard had failed.

Immediately, Luna realized something drastic had to be done. There was simply too much at stake to let something so dire as them being ponynapped transpire again. She needed a plan, some way to ensure that should she, every other princess and Equestria's most valiant defenders fall, there was still somepony to rule in their place. A pony to rule Equestria in their absence. A secret line of defense!

As the abrupt idea crossed the midnight alicorn's mind, she smiled to herself, the spoon Luna held in her muzzle shifting with her lips as she did so. She needed a secret successor, one only she and a select few other trusted ponies knew of. An undercover prince or princess. That was where she ran into a problem, however. To be a true ruler of Equestria, the kind of ruler ponies would look up to and follow, ideally one would need to be an alicorn, and if she or her sister were out of the picture, an alicorn with power enough to bring the day and night.

Luna's head sank slightly at that realization. There were only two ponies in existence with that kind of power, and she was one of them, with her sister Celestia being the other. Then again, she was the almighty princess of the night, and would not allow such a simple obstacle beat her. She owed it to her subjects to do all she could to ensure their safety, especially after her own past transgressions as Nightmare Moon. She needed to make sure there was somepony to take over should the worst happen, and she knew there was only one way to achieve such a thing.

At having that idea, a strange mix of determination, curiously and anxiety came over the princess's mind, yet she was not about to allow any of those feelings to define her goal, especially the latter. Therefore the more she resisted her doubts, the more that idea formulated in her mind. To get what she was after, to get the perfect successor and ensure Equestria's survival, she would first have to give up her body, for if she would not continue the royal bloodline who else would? Surely her sister wouldn’t. It had been thousands of years, and she’d yet to even consider having a royal foal after she’d been appointed Princess!

At that fact, Luna had made her decision and got up from the table with an abrupt start. She knew now that she'd have to plan it all out of course. First, she'd find the perfect sire to the little prince or princess she’d carry, but surely one of her guards would be willing to donate their seed to such a cause. Assuming that, she'd have to find the very best stallion to offer her the seed of Equestria's future. Then there was her part of carrying the foal and all the physical demands of that, but she was prepared to carry a foal for her country. Besides, what was eleven months to a being who'd lived as long as she had? After giving birth, she'd mold her heir into the perfect ruler in secret, keeping them in the shadows should Equestria inevitability require them.

One again Luna smiled to herself, the fact that she'd come up with such a flawless plan under such short notice making her feel a little giddy. In the end, however, she knew she'd do anything for her subjects. It was then that the alicorn moved around the long table, a new purpose set into her regal strides, yet as she was about to reach the chamber's door, the great entrance opened to reveal the glorious white form of her sister, Princess Celestia.

"Oh, hello Luna, my dear sister. Please do forgive my sudden entry, as I did not expect to find you here so late in the day," the graceful white alicorn said with a smile.

Warmed as always by her sister's kind expression, Luna offered a small glance in return."Worry not dear Tia, you are not interrupting anything, in fact, I was just about to retire to my bed chambers," Luna responded, nodding to the door through which Celestia had entered.

As Luna looked at her sister, another barrage of thoughts stormed her mind. Should she tell her what she was contemplating? Maybe she could even convince her to do the same? After all, neither of them had even considered continuing their bloodline before now. At least, not since their long forgotten days as excitable teenage fillies. Yet as Luna looked up into her sister's eyes, watching her graceful expression sparkle in the dawn’s radiant glow, she decided against telling her.

Celestia had enough to deal with as it was without this on her mind too. She had been the princess looked up to by millions for the past thousand years, and surely what Luna was about to do to herself would be too much for her sister to take on and still govern Equestria. Plus, one pregnant alicorn would be enough to hide, there was no need for another to potentially ruin the secrecy.

"Well, I will bid you goodnight then dear sister. May you have a pleasant rest." Celestia responded with a courteous bow.

Despite everything she was thinking, Luna couldn't help but smirk slightly and each of her rear legs shifted with a hint of excitement as she nodded."Thank you, Tia, I intend to make it most pleasant indeed." At that, Luna swiftly departed back into the castle halls, leaving Celestia with a rather puzzled expression.

The princess of the sun pondered her little sister's words for several long moments, but her thoughts were assailed as she heard a ringing come from the castle kitchen. Today would be a busy day for her and, as always, breakfast was indeed the most important meal.

*******

Despite being the great princess of the night, one of the most powerful equines to ever live and having a whole battalion of willing and eager stallions at her command, the idea that Luna could have brought her plans to fruition in a mere day after conceiving them might have been slightly naive. The fact that she was now walking along one of the castle's great corridors in the middle of the night, almost two weeks after initiating her plans, was a testament to that fact. But that was not to say she had not engineered the situation perfectly.

Luna had come and spent the last few days rigorously watching all of her finest male guards; keeping track of each of those she knew to be the best among them. Most of the finest stallions were bat ponies of the first platoon of the royal night guard, the very soldiers set to guard her personally. That also meant they had been the ponies to fail to protect her against the Changeling invaders too, but that she could overlook. That oversight was mostly due in part to her determination to secure Equestria's future, but she couldn't help but admit looking at some of the large stallions she had at her command did indeed please her on a more base level as well.

It had been hard to diminish those feelings of desire since she'd had the idea to take one of them as the sire for her future heir, and all that entailed. Once or twice she'd been unable to stop herself from shooting one of the guards a sultry look, or exaggerate her movements as she passed them by, making sure they'd got a good glimpse of her hips as they swayed.

Out of all of her guards, one large bat pony stallion in particular had caught her attention. One, that through extensive research, Luna had discovered had excelled in all aspects of his training. Serving in her royal guard since only shortly after her return and cleansing by the Elements, and for all intents and purposes, looking more fine than anypony she'd seen in a very long time, he was the perfect fit. The perfect sire to her foal. The fact that he was a denizen of her night also helped, and, while it had not been necessary, her child’s father being a bat pony was preferable. Luna had known from the beginning that, with no male alicorns, her offspring would never be truly pure, but she was hoping with her body as the catalyst, and the seed of a pony of the night, that the foal would be as close to an alicorn as anypony could be.

Luna had taken further preparations too, the first of which being to make sure that her chosen sire had been stationed to guard her chambers on this night, the night of the full moon. Luna's reason for choosing this night had been very simple: she was in heat during this time every month during the breeding seasons. It had not been too hard to anticipate the peak of her cycle, when she ovulated, which often coincided with the phases of the moon as it had done for most of her life.

Furthermore, while centuries of restraint and discipline had somewhat numbed her mind to her primal urges, right now, with all of her current thoughts and raging hormones, she yearned more than ever to watch a stallion's hard length force its way between her burning folds. To fill her with the warm seed of a future ruler of Equestria. Her being in heat and ovulating also denoted her fertility, and getting pregnant was her real mission after all. Despite her thousands of years of pent-up desire, she didn't want to have sex more times than needed to in order to conceive. Ideally, just one breeding would give her the foal Equestria so needed.

Yet the more she thought about having sex, of feeling a foal being shot into her womb, the more Luna imagined the immense pleasure she was about to feel and the release from the itching pressure in-between her thighs. The more she couldn't help but long for it. Even now, she could feel the burning swelling within her rear end, and she could sense the tightness in her pussy as she walked. As she rounded the corner she saw him, by the grand doors of her bedchamber. Standing there, beside the door was the stallion that would set her free from the torment of her lust, her stud-to-be.

Dusk Hunter, that was his name, she recalled. He was tall and strong. Muscles rippled beneath his smooth blue coat. He had leathery blue wings and a pair of sharp green eyes shone like gems from below the rim of his dark-purple helmet. His mane was a midnight blue, similar to the color of her own, and a pair of sharp fangs glinted as they peeked from his mouth and rested over his lower lip.

Most of Luna's thoughts were set solely on controlling her aching marehood as she awkwardly approached her room, and her guard. At this rate, she felt like she could explode merely from the act of walking and feeling her tail rubbing against her swollen marehood, centuries of pent-up tension begging to be released. In light of such intense feelings, Luna made a swift effort to reach her room, battling a grimace as the pressure, the need to be bred, bubbling within her, and pressed her hoof to the doors. She looked at Dusk Hunter coyly as she did, remembering that he'd been one of the guards she'd teased over the past few days, and it wasn't hard to see now that those little glances he'd gotten under her tail before were playing on his mind.

Dusk, for his part, was doing all he could to remain stoic and to stand straight as Luna shot him another wry look. Even so, he couldn't help but notice the strain in her expression as she battled her overwhelming desire to rut, nor could he ignore the arched way she was holding herself against the door. He could smell her too, that strong musky scent of estrus, of fertile mare, was emanating from her like the scent of fresh bread would from a bakery. He saw that she was now looking at him, just as she had several times during his last few shifts, only that this time she was really looking at him.

"Your highness," Dusk stated with respect, holding himself up straight even as he felt a small flame of lust ignite within him. A fertile mare’s pheromones were a powerful thing, after all.

Luna rose as tall as she could without disturbing the building passion in her rear, and looked over the smaller guard."Dusk Hunter, that is your name is it not?" Luna asked, knowing full well that she was correct.

Dusk swallowed, and nodded, feeling the intense weight of those age-old eyes peering down at him. He could see the moonlight sparkling in the sapphire orbs like hundred of tiny stars, but a growing fear was only doubled, however, as Luna relaxed, and those magnificent eyes became soft and lidded.

"I see you have been selected to guard my chamber upon this most glorious of my nights, but might I ask something else of you?"

At her words, something in Dusk's mind was taken back to only a few hours ago. He'd been told by one of his commanding officers that he was to stand guard over Luna's chamber tonight instead of taking his regular position of patrolling along the castle’s walls. Right then and there he'd only had one or two suspicions, based in part on how he'd been seeing the princess watching him over the past few days, but ultimately he'd thought nothing of it. Right now, however, he was thinking about it a whole lot more.

"Yes your highness, I am but your humble servant, I would do anything my noble princess may ask of me." Dusk said, and bowed as those words left his muzzle, unable to help but feel the hotness between his rear legs as he lowered himself in an effort to distract himself from the feeling of himself slipping from his sheath, he set his tongue to work licking his fangs.

Luna's smile became a smirk as she pushed a hoof against her bedchamber door, slowly forcing it open.

"I see. You’ve served your princess well before, and now I think it is time you were rewarded." Luna said as she slipped through the door into the darkness of her room, swaying her rump and swishing her tail across Dusk's muzzle.

The bat pony's tufted ears stood tall, and his eyes seemed to swim as he got a face full of her glorious musk. The musk of a mare in heat.

"Please, follow your princess Dusk Hunter, she wishes to see you in private," Luna beckoned, and, despite all of the alarm bells and years worth of discipline, Dusk followed Luna into the shadows of her room.

That instinctive sensation deep within him was growing, and it was growing quickly. It had been several months since he'd spent any decent time with a pretty mare, let alone had the pleasure of sharing a bed with one. In the guard it was a common belief that those in service to the Princesses must remain pure and untainted by temptation, lest their wrath come down upon them, but right now his brain's most basic drive was throwing all of that out of the window. Of all the mares in Equestria he'd resisted the allure of, he could not dismiss that of the magnificent mare he'd sworn his life to protect. His princess herself.

Luna, meanwhile, peered back at the entranced guard as he trailed blindly behind her. And, with a flash of her horn, she shut the door behind him and released several orbs of magical blue light into the air. The orbs danced about her bedchamber like fireflies, bathing the two ponies below in a glow comparable to blissful moonlight.

All Luna could think as she looked at the nervous looking stallion, however, was how easily she'd gotten him exactly where she wanted him. The more time she wasted, however – the more she breathed his powerful musk, the scent of a virile stallion – the more the itching heat of her urge to breed swelled, and the more she yearned to feel him mounted atop her and his cock within her. Now it was time to get to the most important stage of her plan to ensure Equestria's future. To have this stallion breed her.

With one fluent spin of her hooves and body, Luna turned to face Dusk and slowly began backpedaling towards her bed, her eyes studying his every feature, carefully removing her royal regalia as she did so. All the while Dusk just stared at the magnificent princess of the night in awe as she undressed, her deep blue coat and ethereal mane looking no less beautiful now she was without her chest-piece or gilded shoes. Yet the more he looked at her, the more the scent of her readiness to mate tortured his brain. It was no secret now that the heat of his lust had grown into a raging erection that swayed between his thighs bobbing in time with his heavy breathing and racing heart. His cock was swollen to bursting, and he had to do all within his power to hold himself back to avoid wasting all that had been building within his bulging balls for so long prematurely. That battle was only made all the harder as Luna threw herself on the bed then faced him.

"It is no secret to me that you have noticed my predicament Dusk, but the rather extravagant evidence you carry below your haunches will provide quite the solution I'm sure," Luna stated, pointing a hoof to Dusk's throbbing cock as she slowly slid her bottom half over the edge of the bed, her hooves on the floor and her chest against the bed. "Yet I wonder, might I relieve you further?" she teased, as her magic slowly undid the buckles of his dark-purple armor and levitated it away from him.

As Dusk watched himself be disrobed, he couldn't help but feel how naked and vulnerable he was becoming. He was utterly paralyzed by Luna’s stunning beauty; she was like a siren that had caught him in her song. Being this exposed so close to her while she was like this was like standing only inches from a burning star without any form of protection. She radiated with an aura that almost scorched his coat and seared his hungry eyes, and her musky scent was far too intoxicating.

As Luna lay there on the edge of her bed, fidgeting playfully like she was some kind of teenage school filly, Dusk still tried with all of his might to resist running right at her and mounting her, rutting as hard as his stiff meat wanted him to. Because of the perceived rules of purity, he'd been unable to really enjoy himself in far too long. Despite all he was feeling, and with the Princess all but presenting herself to him, and that this felt hideously ironic, he still resisted her as much as he could. That last bastion of restraint was about to run out, however.

"This is my decree: I wish for you to please me in a way only a noble stallion like you can. Mount me, please me and make me your mare!" Luna said, flagging her tail and revealing her dark-purple treasure to the stallion.

Luna swiftly spun herself over, propping up her rear and flicking back her tail as she leaned against her bed and presented herself to him fully. She spread her hind legs the best she could to relieve her inflamed marehood, as well as giving a wide open invitation to the horny stallion. Within seconds, the unbearable longing in Dusk's loins, the need to mount and breed this fertile mare, took hold and he bolted forwards like a hungry dog. Luna swiftly felt his firm weight rest upon her back in an instant as he wrapped his forehooves around her shoulders, mounting her. She flared her wings and shifted, moaning softly as she felt the hot tip of his cock brush against rump, seeking her searing marehood. Now more than ever she longed simply for him to force his way inside her and rut her all night, with that only enforced when she felt his flare land right on target, pressing against her lower lips.

"Of course your highness, I live to serve you," Dusk growled, tongue falling between his fangs as he kissed her soft neck and, with a forward shift of his hips, slipped his massive length inside her desperate pussy.

Luna felt his flared tip part her wet folds, and an instant sting of pleasure shot through her, igniting her every nerve ending like a lightning bolt. She fell forwards against the edge of the bed as the weight of the large stallion shifted back, the warm arc of his crotch pressing against her rounded haunches as he reached out and lay a series of wet kisses along her quivering spine. Instinctively, Luna wiggled her hips, shifting so that the full length of his hard cock would easily slide all the way inside her, her kneading muscles encouraging him even deeper. His pulsating rod was harder, not to mention far bigger, than even she'd anticipated, yet she was an all-powerful alicorn princess and she knew she could take it all. She wanted to take it all!

In that moment Luna craved nothing more than to feel all of his massive stallionhood forcing its way right up into her. She was mentally begging for that sweet relief from all of her sexual frustration, and most all she yearned for him to pound her until she was filled with all of his glorious seed. She let out another long groan as she finished shifting herself again, feeling his firm length slide right along the silken walls of her burning pussy until even his medial ring was forced inside her.

"Oh, Dusk Hunter you please your princess well. Now, fulfill my decree and fill me with your love. Breed your princess!" Luna cried out. Despite feeling that she was no longer in control of the situation, she couldn't help but love being subjugated, and without question Dusk obliged.

"Of course my princess, I live to please you!" the bat pony muttered into her ear, a hint of satisfaction in his strained voice as he scraped his fangs along her spine, forcing her to shiver.

Without anything further, Dusk took Luna as his mare. With all the force he could muster, he pulled back before slamming his full length right into her pussy. Luna gasped, clutching at the bed sheets and bearing her teeth as she felt him unleash all of his pent-up frustration into her all at once. She could feel his thick shaft ripple against the heated walls of her wet marehood with each throb it made within her, then shivered at the ticking kiss of his bulging tip against the walls of her marehood. She truly had chosen the right stallion for the job, and right now she was enjoying every moment of it.

"Oh, oh, oh, princess I'm going to fulfill your command over and over until you're begging me to stop, I'm going to stuff you so full you won't be able to walk right for weeks!" Dusk howled as he thrust into her again and again, pressure growing deep in his core, bringing him closer and closer to climax the more he felt her pulsating, winking pussy clamp down on his stiff rod.

Luna didn't respond with anything more than pleasurable moans as she shifted again, taking all that she could of the stallion as they both rutted into a frenzy. Clearly she'd appealed to Dusk's more primal side, and right now he'd completely given into his instincts. He was rutting her like some common whorse and, regardless of her plans or the future of Equestria, she simply wanted him to pound here all the more.

The further Dusk pushed into her, the more she tightened her aching muscles around his entirety until Luna felt his unending assault breach the very deepest fathoms of her pussy. She held herself as firm as she could as she felt her dilated cervix part easily against the relentless pounding, and over and over she clamped down on that hard length, milking him for the glorious cum she so desperately craved.

Oblivious to the complex motivations of his princess, Dusk pressed on and on, a slave to his instincts as he crawled further up onto Luna's back until his swollen balls were bouncing against the refined curve of her royal rump, his thrusts short and deep now as he started to flare.

"Oh-ho princesses, any further and I'll be balls deep inside you, think you can take all of me, my great lady of the night?" Dusk asked as he slammed into her again, putting such a bold statement to the test as he forced every single inch of his monstrous cock right up into her, filling her whole tract with his length.

Luna grunted and pushed back into him, eagerly accepting everything he had to give her. She didn't say a word, but she was not about to let him say that without a fight. As much as she found herself coming to love being dominated for a change, the more she felt the swirling sensation of orgasm building deep within her, the more she wanted to simply let him have her.

"No answer, huh? Well, I guess you’ll just have to lay there and let your loyal guard do all the work." the stallion exclaimed and, at that, Dusk pulled back a hoof and slapped it against her right flank.

In response Luna arched her neck and pushed her rear right into him, encouraging his rutting as her clit continued to wink, her inner muscles doing their damndest to set him over.

Dusk’s leathery wings began to beat, slapping against Luna’s sides again and again as he locked his forehooves around slender hips, now pumping into her with such ferocity that her head was forced into the bed covers. She rocked her body in kind, feeling the very tip of his cock flare as he taunted her again. He was right on the edge, ready to give her all of his cum directly into her ready womb.

"Is this what you want, princess? W-Want me to c-cum in you?! I-I-I think I'm r-ready, I'm...c-cu—" Dusk's stuttered words were cut off as she felt him finally reach his climax deep within her, and his bulging tip erupted.

Luna felt a great surge of his warm cum flood into her pussy with alarming ferocity, then he pulled back and forced himself deep inside her as he filled her again, pumping into her over and over, giving her the seed that would ensure the future of Equestria remained secure. Luna relaxed her pussy for a brief moment, then she pressed down on his cock with all of her remaining strength, repeating those motions as she milked as much cum out of him as she could. That flame that had been ignited within her core was still growing and as she squeezed his pulsing cock within her and felt more and more of his hot cum pouring into her womb, him filling her like a whorse, she felt her body tense. Her eyes closed, her whole body feeling tingly as she bared her teeth.

Dusk let out a pleasured sigh, his tongue hanging limply from his mouth as he continued his long overdue work, his hips pumping again and again as he felt a pleasure build within his cock and each time he'd fill Luna with more and more of his hot cum, feeling her body milking him of his virile seed. As he kept cumming inside the fertile royal’s womb, he couldn't care about any future consequence at all. All he could think about was how much more he was going to pound this gorgeous mare, and how much more of his life-giving cream he was going to pump into her, not even considering how she may very well get pregnant from him.

It was no secret to Dusk that his Princess had not yet reached her peak, and even as he pressed all the right buttons in her smooth love canal, he could feel just how tense she was becoming as her body lingered perilously on the edge of orgasm. After all this, after resisting the urge to rut for months on end under the fallacious belief that the very mare he was now rutting would scorn him for fulfilling such a deeply-rooted need, a small bit of poetic justice seemed to be in order.

Luna felt Dusk's hot, sweaty body shift again as he jerked back, pulling his cock right back to the lips of her soaking wet pussy. She could hear the bat pony's growls between his rigorous pants, his breath escaping him like that of some fearsome Everfree monster as he slowly rubbed each of his forehooves over her juicy plot. His cock's still-flared tip twitched in the entrance of her marehood, teasing her as it dripped with his cum and her warm fluids. All the while, however, Luna could only wonder why he had stopped when she was so close. Could he only endure so much of her immaculate body? Had her royal pussy had simply tired him out? She had what she needed though, as she could feel a virtual lake of cum sloshing around inside her bloated womb. In a way the added weight made her feel like she was already pregnant.

"My dear princess, you’re so tense…why are you holding back? Have I not pleased you?” Dusk asked, slapping another hoof against her curvaceous butt, causing it to ripple.

Luna quivered, grumbling as she felt a burst of heat run through her. She still found this overwhelmingly hot. He was right about her, though. She was not yet pleased. She’d yet to have her own needed release. Luna arched her neck and looked back at the exhausted stallion.

"No, you are right my servant. You have not yet allowed me to taste my own sweet release. Come, please me more so I may be filled with all you have to offer." Luna said salaciously, and for the first time, she felt like she was truly demanding something from him. Not that he looked like he was about to disagree.

Even so, he was still moving too slowly for Luna's taste. The future of Equestria was secured within her womb in a thick, gooey pool, but most of all Luna wanted to cum now. She had not come this far to be denied that luxury; if she was going to carry a foal for the next eleven months, she may as well enjoy its conception. Without warning, Luna rammed her rear back up against Dusk, jamming his hard cock back inside her as she wriggled her hips and began to gyrate furiously, her clit winking constantly in response.

It didn't take Dusk long to get going again, even if his endurance was clearly fading after his first prolific seeding of this mare. He seized her hips with his forelegs and began to pound into her again, and after a few more minutes of mating his mare he was filling her already bulging womb with yet more of his glorious cum, crying out as he held himself hilted into her deepest passage and filled it full of his essence. Luna cried out in utter pleasure as she felt her orgasm edge closer and closer as each pulse of foal-batter filled her even fuller. This would be the first time she'd felt such a thing in over a thousand years, and she was about to savor it forever. Savoring the moment she was given her foal.

"Does this please my great princess?" asked Dusk as he shifted forwards again and pushed his flared head into her womb once more, compressing his cum into her even more. He hooked his forehooves over her shoulders and planted kisses on her neck as he brought her closer and closer to the final burst of ecstasy, his hips still shifting slightly as she milked the last of his load into her.

"Yes, my loyal servant y-you served your princess well. Now p-please just allow me to cum!" Luna grunted, those words coming out a little more strained than she'd have liked, but as she edged closer to her orgasm she didn't care.

More and more cum filled her as she shifted, desperate to get into the perfect position before she finally broke under the heat of her deepest desires. Then, just as her lover asked her if she was pleased by his actions once more, a flash of blinding pleasure lanced through every single fiber of Luna’s yearning body and she released all of her pent-up feelings all at once. Her body milked his cock and brought his seed into her womb as she coated his throbbing cock and his crotch with layer after layer of warm mare-cum. She uttered a cry of ecstasy, stretching herself out over the bed as her whole body thrummed with pure, pleasurable, bliss. Moments later, the strength of her lover finally gave out, and knowing he'd served his princess well, he fell limply across her back as his tired breeding rod finally slid out of her, a thick glob of his cum trailing after his still-swollen flare.

In union, the pair fell onto the covers side by side and as Dusk panted heavily, Luna rolling onto her back to stare up at the laminated ceiling, trying to prevent his seed from escaping her as well as gravity encouraging it even deeper into her uterus. She hadn't felt like this in far too many centuries, and right now the warm feeling of pure satisfaction that radiated from between her legs was unrivaled by anything she could imagine. As she felt the warm mass sitting in her womb and coating her passage, she knew that surely her plan was to be a success. It had to be, for the future of Equestria.

Looking down over herself she couldn't help but smile at the glorious work of her exhausted lover. Her view of the bottom of the bed was obscured by her distended stomach, the likes of which rippled like liquid as she tapped it with a hoof. She knew that with that much cum inside her while she was undoubtedly ovulating, there was no way she would not conceive, and indeed looked at least three months pregnant right now.

Shifting slightly, and feeling the added weight of the warm seed swirling within her bloated stomach, she wondered if this was what it would feel like to bear a foal. She imaged the life blooming within and growing within the safe walls of her womb. She thought about what it would feel like when her foal moved and kicked, and what she would do when the day came that she would bring it into the world.

All that was for consideration for later though, as right now she was just content with laying back and feeling the warmth of her the seed bubbling within her. There were still hours left until she would have to lower the moon, plus she had no idea how long it would take for the mass of cum inside her to go down. She turned to Dusk as he lay sprawled out beside her, one tired eye open as he regarded her. She smiled at him, before rolling onto her side to face him, a movement that was made considerably more difficult by her slightly swollen belly. Dusk took one look at her and what he'd done and smile back, fangs flashing as he did so.

"Wow, I really filled you up good princess," he observed, reaching out a hoof to rub her belly, causing the hot liquids within to ripple. "I didn't even know I could cum so much! It looks kind of weird actually…almost like you're pregnant or something."

Luna's smile grew a little more as he said that, and she glanced down at her bulbous bump, before looking back at him. Dusk Hunter caught her somewhat whimsical look, and his smile became a little crooked.

"Princess, what is it?" he asked, his suspicion finally managing to break through the heat of his instincts. The realization that he’d just planted his seed inside of a fertile princess’s womb, and its implications, finally coming to light.

At that question, a small level of guilt bloomed within Luna's mind. If her plan was to succeed there was one last thing she had to do, something she'd neglected to mention to the stallion. Nopony could know about the secret heir to the royal bloodline, not even its father.

"Pregnant? Yes, I think it will be quite desirable when my belly starts to swell with your foal.” Luna responded, as her horn began to glow softly.

Dusk flinched slightly as the magical aura began to illuminate her face, his suspicion turning into mild worry as Luna slowly shifted her swollen body forwards, and pressed her horn to his forehead lightly.

"I am truly sorry to rob you of your memories of tonight, of becoming a father to a prince or princess, my faithful servant, but if I am to ensure the safety of all of my subjects, you may not possess the memories of this night."

Dusk Hunter moved to raise his hooves, opened his muzzle to say something. But before he could Luna's horn gave a bright flash of light and in an instant her face was gone, his mind falling into the darkness of unconsciousness.

Princesses Celestia sat at the head of the long breakfast table, smiling happily as she sipped a cup of hot tea and studied the day's morning newspaper to her right. She knew all was well in her kingdom and in fact, there had not been any trouble since the attempted Changeling ponynapping almost six months ago. Most of the tabloids and headings nowadays just involved silly stories about celebrities, and gossip that she knew would not last very long. There was, however, one thing that did catch her eye amidst the nonsense on the paper, specifically a small article involving her sister Luna.

"Princess Luna, Not Seen In Weeks!"

"It has been almost eight weeks now since anypony has seen princess Luna publically, not to mention that all inquiries into her whereabouts have so far been dismissed by castle staff and even her sister Princess Celestia. Right now, many ponies are wondering the same thing: what has happened to our beloved princess of the night?"

Celestia let out a small sigh as her eyes passed over the words slowly. It seemed ponies would find a way to question anything these days. Nevertheless, as much as she hated lying to her subjects about her sister being missing, she didn’t have much choice. Luna's somewhat imperative nature had seen to that, as had it seen to...well, one other thing. One very big thing that was only growing by the day.

Celestia clenched her teeth at the thought and took a deep breath. There was no way she didn't trust her little sister or her decisions. A part of her even agreed with what Luna had done, not that she'd care to admit it to her. But for all that, she wished Luna had at least told her what she was planning before actually going through with it, for the most part because of how impacting a revelation it was to her, and in a very small part because she felt a little jealous of the experience Luna had told her about.

Celestia straightened herself at that and collected herself swiftly. There was no way she was jealous of her sister’s night with that guard, no matter how much she craved companionship. It was at that moment, however, that the doors behind her opened, revealing the regal form of her younger sister .

Celestia looked back at the smaller alicorn over her shoulder, noting, once again, that this was a very late time in the day to be seeing Luna, as it had been those many months ago. Then again, Luna's behavior had been in a state of turbulent flux for some time now, as was to be expected from a pony in her condition. Luna, however, did not look tired, instead looking like she was positively glowing more than usually. Her tall form was as regal as always and her graceful body was as magnificent as it was every day, her belly lithe as always. It was that, however, that made Celestia frown slightly.

"Good morning little sister, I trust you had a fine rest?" Celestia greeted as Luna strode into the dining chamber with her head held high and proud.

"I most certainly did Tia, though I fear such things will not last much longer...things have been getting, well let's just say a little restless lately," Luna explained, looking back over herself as the words left her mouth.

Celestia nodded once, then let out another sigh as she looked over Luna's slender figure too.

"I see..." Celestia said as she took another long breath. "Luna may I asked you why you hide it from sight? If you went to so much trouble to be with a foal, why disguise it as you do? Are you not proud of carrying?"

Luna looked up at her sister sharply, her glare half insulted and half shameful as she blushed a little."N–No, I'm not ashamed at all of being pregnant, and of course I am proud of it. I simply do not want to ruin the secrecy of what I have intended," Luna explained, but her sister's sour look only persisted, with Luna knowing exactly what her sister expected of her now.

"Urg fine!" Luna finally grumbled as her horn lit up with a magical aura that soon spread down to her stomach, stripping away the magical illusion that disguised the rather obvious swelling of her five-months-pregnant belly. "But I must be sure nopony other than you sees this. I would hate to have to steal another's memories. Having to rob the father of knowing he’d sired a foal for me still hurts me to this day."

Celestia's expression lightened at the sight of her sister’s bulging belly, which held what was soon to become her first niece or nephew. She pushed all of the doubt and the frustration at her sister's naive decision to have sex in her heat and get pregnant to the back of her mind. None of that really mattered now as it was already done and in progress. All that did matter was the health of the coming foal.

"Luna, you're getting so big already! The foal must be very healthy. I'm so happy for you!" Celestia said, clopping her hooves together joyfully for her sister.

Slightly embarrassed by her sister's blunt statement regarding her rapidly expanding belly, Luna's dark cheeks reddened further as she smiled. "Yes I am aware of my size, and I can assure you that they are very healthy. I checked them both with the spell I found in the library only a few hours ago," Luna reasoned, her pride at having done so diminishing her embarrassment a little.

At her words, that there were more than one foal Celestia paused. Then the princess of the sun looked at her sister with pure glee.

"Both of them?!" Celestia exclaimed, and once again Luna offered her a bashful smile.

"Yes, dear sister it would seem I'm expecting twins, a filly and a colt if my magical talents prove to be correct." Luna looked back at the sizable bump in her midsection, feeling the swelling life within as it shifted and kicked against her insides ever so softly.

"Oh congratulations, my dearest little sister, I can't believe it I'm going to an auntie to two foals, a niece and nephew! Oh how wonderful!" Celestia gushed, moving over to hug her little sister.

Luna couldn't help but relax slightly at her sister's touch, leaning into the larger alicorn’s soft white fur as they embraced. Celestia moved to her sister’s swell, and within moments was marveling at Luna's squirming belly as if she herself were the foal's father instead of some guard who could never know that fact.

"I am glad to see that you are able to now look past your blunt judgment, Tia. I was afraid you may react to this news as you reacted to how I first told you," Luna admitted, then she winced slightly as she felt a hard kick from within her.

"Oh, they're kicking, Luna!” Celestia said, her hoof on her sister’s belly as she felt the foal within kick against its mother’s womb, “Awww–I couldn't be mad at you for this! As much as it may one day present problems, I'm sure they're things we can overcome together, especially for the good of the foals." Celestia responded, laughing to herself as she pressed a hoof against the spot on Luna's belly that had just shifted, pure joy within her heart at the thought of her sister becoming a mother.

"Well Tia, if you weren't going to continue the royal bloodline then who was? I'm glad you are finally seeing things as I do," Luna said, craning her neck so she could get a good look at her moving belly too, a swell of motherly pride overcoming her. "Ooof, they really are active today. Hard to believe there's still six months left until I can hold them in my hooves."

"I don't know how you cope with the morning sickness and the added weight of carrying them Luna. I can imagine it's a beautiful experience knowing you’ll soon be a mother to two, but having two foals inside you? The next few months are not going to be easy," Celestia explained, and once again a proud smirk appearance on Luna's face.

"It is not that bad dear sister, in fact, I rather like it. The feeling of life swelling inside me is wonderful, not to mention how blissful the experience was that put them there," Luna almost purred into her sister's ear, and in an instant, Celestia went stiff. "Maybe you should try it yourself, Tia? Surely we can use more heirs to the throne. We wouldn't want anything to happen to Equestria should we perish, after all. Plus, the fact that I can tell you truly wish to be bred and become a mother. I could never forget the dreams you have of holding a foal close to you, your foal, that I so often encounter when I dreamwalk."

Celestia's erect ears twisted and she allowed her eyes to slowly drift upwards towards Luna's sly expression. She couldn't deny that after so many years of the same thing each day, a new experience was something she craved more than ever. That wasn't to say the act of lovemaking was new to her, but the feeling of being impregnated, of being bred, and bearing a foal, an heir to ensure the safety of her kingdom, certainly would be. Surely she owed herself that, the joy of having a child of her own to love and cherish, to raise and teach to rule in her place should she perish.

"Is really that pleasurable, sister? To be filled during your estrus and carry a foal?" she asked, and seeing her sister's newfound curiosity as clear as day, Luna nodded.

"It most certainly is, dear sister. Plus I'm sure one of your guards would be just as eager to serve you as mine was to serve me. Just be sure to choose only the best sire. After all, we want only the strongest genes for our royal bloodline,” Luna said, giving her sister a suggestive, knowing glance.

“Besides, I’ve seen the way you are always looking at Sun Streak…” Luna added coyly, “Perhaps he would be a good choice as a sire to your heir?”

Celestia swallowed nervously, then looked to the open door to where she knew a pair of guards, including the named one, were stationed nearby. She bit her bottom lip, glancing back at Luna as the dark blue alicorn once again cast an illusion over her maternal belly, then motioned to the open door with a nod. “Go on my dear, your current estrus won’t last forever…”

Forcing back her doubts, Celestia turned back around and opened her muzzle to call out."Guards, please come here, your princess wishes to speak to you."

Securing Equestria's future was her ultimate goal of course, but why shouldn't she have a little fun of her own in the process?

Author's Note

So here we are, my first sex story. Tried to go for something a little more simple this time around, but this was very interesting to write. So while this was requested I may do more stories like it in the future.

Regardless, thanks for reading and I hope you enjoyed!
