Celestia is convinced by a pregnant Luna to help her in her task of creating a line of heirs to the royal bloodline.

Five months after her sister's genius plan to create a secret guardian of Equestria was put into effect, Celestia is convinced by a pregnant Luna to help her in her task of creating a line of heirs to the royal bloodline. Giving in to the overwhelming temptation, her intense estrus and desire to breed, Celestia finds herself a handsome stud of stallion to impregnate her and joins her sister in securing the future of Equestria.

What ensues are several blissful nights of fun, pleasure and just as many long months of arduous and tiresome pregnancy. Even so, who says a mare's last night of fun has to be the one on which she conceives? Especially if it's all in the name of saving Equestria's future!

Chapter One: Conception

Chapter One: Conception

"I don't know how you cope with the morning sickness and the added weight of carrying your foals, Luna. I can imagine it's a beautiful experience knowing you’ll soon be a mother to two, but having two foals inside you at once? The next few months are not going to be easy," Celestia said as she stood in the dining hall with her secretly-pregnant sister whom was six months into her term, and once again a proud smirk made an 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 one Luna named, 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 couldn't she have a little fun of her own in the process, and perhaps even gain a lover in the process? It had been far too long since she'd last had a true lover after all and not just a ‘heat buddy’ to soothe her estruses, with the last she could remember being a great number of decades ago when her last passed on.

As she called them in, the two guards immediately came in, Sun Streak one of the two. Celestia looked upon his pure white coat, the same as many of the daytime Royal Guards had, as well as his beautiful orange and yellow two-toned mane and tail trimmed short to regulation standard. The eighteen-year-old just-stallion wore a set of regulation armor and helmet as well, the golden metal only adding to his appeal, accentuating his powerful body that was fit and toned from a daily regimen of exercise and a diet planned by the best nutritionists in Equestria.

Luna departed when Celestia had called her guards, but not before giving her a knowing grin before then leaving Celestia alone in the room with the two male guards, the whole room smelling of her estrus.

“Is there trouble, Princess?” Sun Streak asked seriously, his eyes sweeping the room for any danger, his partner at his side.

They were instantly hit with a muzzle full of estrus pheromones, but both tried to ignore them, more focused on their princess’s safety than their more baser needs.

“No, no, it’s nothing like that,” Celestia said, before pausing.

She thought for a moment about the best way to execute this, before looking to the other guard.

“Gleaming Shard, would you please give the Sergeant and I some privacy? I have something I need to speak with him about, one-on-one.”

Instantly, Sun’s mind started racing to all the possibilities. Was a promotion possible? Conversely, had he done something so egregious as to deserve a reprimand, or worse, a demotion? As the other guard saluted the two and departed, Sun Streak was left alone with the princess.

“I’ve had my eye on you for a while Sergeant,” Celestia started after making sure they were alone, making the fairly-shy pony nearly shrivel before his mighty leader’s words.

Was now the time she would tell him he was going to be court-martialed? Demoted? Sent to the dungeon? But he’d done nothing wrong! Still, he remained silent, simply trying his hardest to retain a stoic expression.

“Yes, ma’am?” Sun asked simply, only just avoiding letting a fearful quiver into his voice.

“Yes. I’ve been watching you, and your performance been very admirable, as it has been since you joined my Guard. I’ve never seen somepony fly through the ranks as quickly as you, with you only being surpassed in that aspect by Captain Shining Armor himself, whom you are well on your way to matching in rank. Your physical tests are also top-notch, with you completing third in physical peakness in the entire Guard, getting near-perfect marks in every category,” Celestia said, indeed having done her research on the stallion for a very good reason.

Sun internally breathed a sigh of relief, all negative thoughts escaping his mind at the praise.

“Thank you, ma’am. It’s an honor to hear that from you, ma’am,” Sun said, his relief evident in his tone of voice as well as his relaxed posture.

“It is for this reason,” Celestia continued, her eyes looking over the guard once more, taking in his well-muscled form, her eyes sliding down to his chiseled barrel – then underneath.

She was subtle of course, getting but a glimpse of his swelling white-furred sheath and same-colored, large testes as he looked away for a moment – the bulging in his sheath undoubtedly a result of his body reacting to her pheromones – before continuing; “that I have chosen you, and you alone, for a...special assignment.”

Sun couldn’t help but feel some excitement at that. Of all of her guards, Princess Celestia had chosen him, and only him, for a special assignment.

“Ma’am, I will do whatever I can within my power to secure Equestria and serve you, ma’am!” Sun said, saluting.

“At ease. I should warn you, though, this assignment is rather… unorthodox, and would require you doing something that will likely change your life forever. I promise you, though, that it is in Equestria’s best interests, as well as my own,” Celestia said, barely preventing herself from pouncing the stallion as she felt her nethers burning and winking beneath her tail, a small trickle of her fluids rolling down her legs as she smelled the musky scent of a virile stallion staying so near to her.

“Your Highness, I took an oath to do whatever I could in my power to help protect my Princesses and Equestria at whatever cost, even my own life if I need sacrifice it,” Sun said, having lowered his hoof upon Celestia relieving him.

He felt some nervousness that he may indeed need to fulfill that oath in order to complete Celestia’s orders, up to and including his own demise, “I will do whatever you require of me.”

“Well then,” Celestia said, taking a step towards him upon his acceptance, “I believe it is only fair to tell you the conditions of your assignment. Keep in mind that you may refuse at any time, in any stage, but I, of course, ask that you do not.” Celestia gulped. “As you can likely smell, I am currently in my estrus period, which started two days ago. I am fertile, and will be for the next three days in all likelihood, as well as likely will be ovulating today or tomorrow.”

Sun gulped himself as Celestia said that, though he was somewhat thankful she had. He’d picked up on her musky scent upon being asked into the room, fighting to keep himself sheathed as that sure sign of a mare’s fertility called to his baser instincts to breed.

“Yes ma’am, I can... smell that, ma’am,” he replied, unsure of what she was getting at by saying such a thing.

“So... onto the details. I have long been thinking of what may happen should I someday die or be kidnapped again, as my sister, myself, as well as all of the royalty, were when the changelings invaded six months ago. I asked myself; who would rule in our absence? Who would command the Guard?” Celestia continued, looking Sun dead in the eyes; “I have no heir to the throne should I somehow die or become unable to rule any longer, no bloodline to continue my rule.” Celestia closed her eyes and took a deep breath. “I believe now is a good time to remedy that.”

At first, the implications didn’t settle for Sun.

“Ma’am? What do you mean, ‘continue your bloodline’? What does this have to do with a special assignment for me?” Sun asked, confused.

Sure, there was a small tickling in the back of his animalistic mind that took heed of the perceived offering as he looked over her; her wings were beautiful and well-groomed, her whole body perfectly healthy and looking like that of a mare in her early thirties despite being several millennia old, surely looking fit enough for carrying a foal. His conscious mind didn’t even pay that tickling urge in the deepest part of his psyche a second’s notice. Surely she couldn’t mean that?

“I will just speak plainly: Sun, you are a genetic marvel. You are very physically large and powerful, handsome, loyal, and your magic talents excel far beyond the common unicorn, not to mention your physical test results are excellent as well. The perfect traits to pass on to a foal. I…” Celestia said, before pausing to ask herself if she was sure that she wanted to do this.

Once this was said, there was no going back.

“Sun, I would ask that you mate with and inseminate me so that we may pass our genes on. I wish to conceive an heir to the royal throne, with you as its sire.”

Sun simply stood there, his jaw agape, until Celestia softly closed it with a hoof.

“I know, I know, it is something very serious to ask so abruptly, and I am very nervous about potentially becoming a mother too, but that is why I chose to ask now when there are a number of days left of my estrus. You may have as long as you need to think about it, but if you have any inclination to agree I ask you tell me sooner than later. My current estrus won’t last forever, after all. If need be, we could wait for my next, but I’d rather not.”

Sun was still thunderstruck as such a bomb was dropped onto him. Princess Celestia had just asked him to... to breed her, so that she may have a foal by him! He knew the Princess was a prankster, but also knew that she always had a tell-tale glimmer in her eyes when she was not being serious. That glimmer was not there now.

“P-Princess? Are you serious?” Sun asked, his voice one of a very surprised pony, “I mean, can you even have foals with a common pony?"

Celestia huffed as she heard of that persistent rumor that she was infertile save to a male alicorn's sperm, having presumed that the birth of Flurry Heart to a unicorn sire would have proved otherwise.

“I am very serious, and I am indeed very fertile to any stallion's seed,” she said with an air of pride, "I, long ago, had the appropriate tests performed, and it is medically and magically proven that my ova can indeed become fertilized with unicorn, pegasus, thestral and earth-pony sperm. I’m the same as anypony else in that regard. You needn’t answer now on whether you will give me a foal, but I ask you make your decision with haste.”

“So, if I were able to successfully get you pregnant... what happens then?” Sun asked, wanting to know just what he was getting into.

“Well, after I’m confirmed pregnant I’ll carry to foal to term, of course, about eleven months give or take a couple of weeks, then will give birth to it,” Celestia said, surprised the stallion didn’t know how a mare’s pregnancy worked.

Sexual education was, after all, standard curriculum in all of Equestria’s schools.

“No, I know that... I meant... with me, with us?” Sun asked, “Will I just be a…sperm donor? Will…will I ever even get to meet my foal? I’ve had always wanted to have a family someday when I was more established in the Guard, but I hadn’t had that chance yet. It’s always something; I’m needed for the Guard, or before that, I was doing something in school or the junior guard…”

Seeing Sun’s sullen, clearly upset expression at the thought of possibly being excluded from his progeny’s life, Celestia immediately moved to comfort his as though he were her foal, instead of the to-be father of it.

“No, no Sun. You would breed me and donate your sperm, yes, but not only would you meet your foal and be there at their birth, but would be involved in your child’s life as well, every step of the way!” she said, and her sincere tone proved it.

Unlike her sister Luna, she had every intention of letting her foal’s sire watch his child grow up and be a part of its life… or, if this pregnancy went well, possibly his foals. She was not opposed to having multiple children, after all.

Sun’s disposition instantly brightened upon hearing he wasn’t going to simply be used for his seed, that he would be able to have a child that he was allowed to be involved with, as he’d always wanted.

“Thank you, Celestia,” he said a large smile on his face.

“Yes, well, you will not very well be able to help me raise a foal if we don’t conceive it first,” Celestia said, feeling a particularly harsh rush of unpleasant tingling and burning in her nether; “As I said before, my—”

“I’ll do it,” Sun interrupted, just as surprised at his sudden outburst as Celestia.

Celestia blinked, looking at Sun with wide, surprised eyes.

“I beg your pardon? I’m not sure I heard you correctly.”

“I said, I’ll do it. I’ll... stud you,” Sun said, looking away.

He himself was surprised at his sudden decision but knew that to pass up an opportunity of a lifetime like this would be something he'd regret for the rest of his life, no matter how much he wanted to dig himself into a hole and die right now from the embarrassment. Him, being the stud of the most beautiful mare in Equestria to him – as well as the sire to the next generation of royalty, which he would be allowed to help raise – was something he still couldn't comprehend being offered to him.

"Well, that was a quick decision. Are you certain?" Celestia asked, still restraining herself from pouncing on the very attractive stallion who'd just agreed to be her mate and potential foal’s sire, her breeding instinct now burning hot at the promise of being finally sated, her empty womb begging for a foal to fill it.

"P-Princess, how could I possibly refuse? You're the most beautiful mare in Equestria. Everypony covets you! You're a kind, funny, wonderful leader... you're like a mother figure to everypony in Equestria and beyond. I... I adore you too," Sun gushed, he himself having held secret, romantic feelings for the princess ever since he'd joined the guard despite the common if completely false, belief that only celibacy among their guards was smiled upon by the princesses.

“Well… I…” Celestia said, at once for a loss of words for the glowing praise she was receiving. She knew many ponies held her in high regard, but to hear it from such a handsome stallion on the cusp of being bred by him...

At this pivotal moment, Sun found everything rushing out of him now in a long-winded confession; "You'd be the perfect mother to any foal lucky to be born to you, and a perfect mate to any stallion who had the honor of being with you in such a way. I've always loved you in a way, Celestia. I'd be proud, no honored really, to not only be your mate, if only for a night, but to give you the foal you so desire in the process. To be the father to a royal foal... to be a father to a wonderful mare’s foal."

It was Celestia's turn to be stunned silent.

"O-Oh... well..." she said, never having found somepony bold enough to be so direct about their feelings with her in quite a few years.

She'd asked this of him of course, but was indeed surprised that he'd volunteered so enthusiastically. Then too he was a stallion, and, knowing stallions, she knew that sex was likely at least one of his motivation, at least by instinct.

"Well..." she said, placing a hoof on Sun's well-muscled shoulder and lighting her horn, "...shall we go to my chamber to fulfill your assignment?"

“Princess, if I may... could I first ask that you... kiss me? I've... kinda always wanted to kiss you... on the lips,” Sun asked, looking rather bashful despite already agreeing to give her his foal, and everything that would undoubtedly entail.

“Of course Sun,” Celestia said, dimming her horn again and smiling softly.

Without further ado, she quickly brought her muzzle to his and, after a short pause, met her lips to his.

Sun felt the princess’s lips on his own and felt faint, taking in the moment; a moment which had only come to him previously in his dreams. The princess was indeed a great kisser after likely having much practice over her many centuries of life, her flavor and scent entering into the stallion’s muzzle – followed by her tongue.

Celestia gently prodded her tongue past Sun’s teeth, giving a quiet, pleased moan as she met her tongue with his, earning a moan from him too in response. They held that kiss for a while, Celestia dominating the clearly-inexperienced Sun’s tongue in a duel of pleasure as she wrapped a foreleg around his crest to pull him close, until finally, it ended with a loud smack of the lips as Celestia pulled away.

“There you go Sun, one kiss, as requested,” Celestia said, giving a grin as she looked at the young stallion, looking into his shocked eyes.

“Uh… yeah, thanks,” he said shyly, “It was… a great first kiss.”

Celestia was once more surprised.

“Y-you have never been given a kiss before?” Celestia asked, the surprise evident in her tone.

She’d assumed the mares would have been all over this stud of a stallion, and was indeed surprised to find he didn’t even have a known marefriend now, nor a small herd of foals sired by him! It was one of the myriad of reason she’d chosen him for this reason, as not to break up the existing relationship that her other choice of potential stud had. After all, asking her adoptive niece and fellow alicorn Princess Cadence to allow her husband and prince Shining Armor to sire her a foal seemed more than a little too forward.

“No ma’am, I was sent to the junior guard pretty much as soon as I could lift a spear. My daddy, being a Guard himself, and his daddy too, insisted that I carry on the family legacy of serving the Princesses in their Guard. I’ve always had to focus on my studies, then my duties, ma’am. I’ve never had time to pursue a relationship despite wanting to since I was a colt, Your Highness.”

Celestia put a hoof on her dedicated guard’s crest, before bringing him in for a hug. She wasn’t sure if it was one of sympathy or thanks for his selfless dedication, but she felt it was only appropriate.

“Thank you, Sun. Thank you for your sacrifices in my and Equestria’s name,” she said, squeezing him tightly to her, before eventually releasing him.

As she thought about it more, that brought up another question.

“Sun, are you a virgin?”

Sun’s eyes went wide at the sudden, personal question, before eventually getting out of his daze and nodding. After all, he’d likely be changing his answer by the time this was all through; sure that this was not the only personal thing that would occur today, if everything went according to Celestia’s request, “Yes Your Highness…”

“Please, call me Celestia from now on.”

“Yes pri—Celestia, as I said before I never was able to pursue a relationship or mares in general. I’ve... never had sex, and the kiss you gave me was the first one I’ve ever had from a mare or even stallion... besides my family I suppose. I am very much a virgin.”

“Well... as attractive as you are, I’m surprised you weren’t using your issued staff to beat off the mares swarming you and begging for your foals every mating season!” Celestia said with a chuckle, getting a deep red blush from her company.

“Thank you, Celestia, that means a lot to me to hear you say that,” Sun replied.

He’d never really been called handsome, though the other guys in the barracks did indeed ask him ‘if he had a marefriend yet’ more often than anypony was asked, and the mares seemed to give him more looks than some other stallions. He never really payed that any mind, but the implications were now more obvious than ever to him.

“You’re welcome, handsome,” Celestia said, before wincing as an intense wave of heat washed through her, realizing the effect the stud before her was having on her.

She was beyond horny now, a small puddle of her thick, fertility-telling mating fluids now soaking the floor between her hind legs, her entire body feeling hot though especially her lower belly.

“So, would you be willing to... proceed with the assignment now?”

“Princ—Celestia, I think we’re past that,” Sun said with his best try at a sexy smile, and Celestia had to say it came out pretty well as another heated wave rolled through her loins. “What do you need me to do? Do I just... mount you?”

Celestia gave a seductive smile of her own, and Sun felt his long-ago-erect member flex in reaction the utterly smoldering gaze she gave him, slapping against his underbarrel.

“You…” Celestia started, circling the sexy stallion like a shark its prey, taking in every detail of him once more and deciding he was indeed the perfect sire, “...don’t have to do anything yet... and especially not in my dining room where we could be caught being so... indisposed. The potential scandal...” Celestia shook her head at the thought, before she then placed her hoof against her to-be mate and lit her horn again, “...it’ll be bad enough when my belly starts to show in a few months and I announce I’m pregnant. No, we shall retire to my personal chamber for such an act.”

Sun nodded in agreement, knowing that the ponies of Canterlot could indeed be fairly... uptight regarding sexuality and in their expectations of royalty.

In a flash of bright solar-yellow light, the two ponies were in Celestia’s grand personal bedchamber. The floor was a light magenta with swirls and other patterns of a deeper heliotrope purple intermittent along it. The walls were phthalo blue with a dark indigo cloud design arcing along the doorway, and in the back of the room was a large star mural tapestry. In the middle was a large bed adorned with dark orchid sheets and a thin summer blanket of the same color, pillows covered in golden pillowcases.

As soon as they arrived, Celestia started gently pushing Sun backward, towards the bed, less than subtly making her desires known as she took off her regalia and placed it into the display case designed for it, leaving her bare and natural. Sun allowed himself to be moved, his hooves moving in sted with hers, until he suddenly lost his balance as the edge of the bed pressed against his back legs and Celestia didn’t stop pushing, Sun falling backward and ending up with his back on the bed with Celestia looming over him.

To say Sun was intimidated would be an understatement, having literally the most powerful being in Equestria, the pony indeed responsible for all of life’s continuation in Equestria by raising the Sun each day, standing over him, a sex-hungry look in her eyes. Soon after, he felt her muzzle nuzzle into his neck, making him shudder, before soon trailing down his chest, earning another, even harder shudder as she buried her nose deep into his sexually-sensitive chest’s fur.

“P-Princ–ah–Celestia?” Sun asked, feeling the motions on his chest stop and those large, beautiful pale-magenta eyes gazing into his own of azure blue expectedly, asking him to continue. “I... I thought when having sex, the stallion was supposed to please his mare first?”

Celestia couldn’t help but give a wide smile at his consideration.

“How kind of you to think of me first, but this is your first time, is it not?” Celestia asked, getting a shy nod from Sun, “Well, as such is so, and I’ve been pleasured many, many times over my long life, I believe it is only fair that you get to go first."

With Celestia’s logic seeming sound to his hormone-driven mind, as well as the increasing urgent feeling in his loins, Sun simply nodded.

“Alright,” he said and, consent now given, Celestia continued.

Sun gasped as he felt Celestia more aggressively nuzzling into his chest, even feeling soft love-bites from her, as her muzzle traveled downwards once more. He felt the nuzzling and nips, as well as what he swore were kisses, trailing along his whole underbarrel as he lay exposed, back legs spread wide, under his princess.

Upon reaching his lower belly, having intentionally avoided the large, most obvious target of her desires she’d earlier felt pressing into her own chest as she’d leaned over him, Celestia gave a quiet, low moan in reaction to seeing just what her guard was packing.

“Well, how exactly have you hidden this all of these years?” Celestia asked, giving the strongly-musky stallionhood a good looking-over.

Sun’s penis was about twelve inches long and six in circumference, quite large compared the average stallion’s of eight to ten inches and four around. It was also a healthy pink and lightly mottled with splotches of deep bluish-black flesh, a feature of stallion cocks which Celestia had seen was different or absent on each stallion she’d invited to her chambers previously.

Not entirely sure how to react, but clearly taking Celestia’s words as the praise they were intended as, Sun gave a contented nicker.

“Do you enjoy that?” Celestia asked in a salacious tone, a small bob from his stallionhood and nod from him answering her question for him; “Well then, you are going to love this.”

Sun watched as Celestia dragged her tongue along his shaft starting at the base, following a trail of musky pre-cum up, before pausing at his very sensitive medial ring, rimming the thick ridge with the tip of her tongue and making Sun squirm at the sensation. He’d never felt something like this before, his hooves or magic being leagues behind this.

“O-Oh wow!” Sun exclaimed, before feeling his hooves being raised in a golden aura and placed upon Celestia’s head; the soft hair of her mane gently shifted under his hooves like an ethereal substance, but by pressing down a little bit, he could feel the solidness of Celestia’s scalp beneath it.

After placing Sun’s forehooves atop her head and hearing his clearly-pleasured exclamation, Celestia continued her ministrations despite the intense need she herself felt, licking along the underside of his hardness until she reached his even thicker flare, moaning quietly as she found a large blob of pre-cum there to enjoy.

All the while feeling Sun’s eyes upon her, Celestia then took Sun’s flare between her lips and into her mouth, his hips shifting up on instinct to the warmth.

“O-Oh-mi-gosh…” Sun squeaked out, feeling the nearly-hot, slick inside of Celestia’s muzzle sliding down his length, his head pressing back into the mattress at the new, but bestially right feeling.

Celestia simply gave a quiet chuckle as she pleasured her stallion, getting him nice and worked up, wanting to make his first time something he’d forever remember as well as making him as pent-up as possible to boot; to make him give her the biggest load he could when the time came. She continued to slowly lower her muzzle on his length, swirling her tongue the whole way, earning soft shudders or irrepressible moans from him. As something got through to her lust-filled mind, just how loud they were being, she lit her horn, casting a sound barrier spell around the room so anything occurring within it couldn’t be heard by anypony outside.

“I could tell you were holding back before,” Celestia said, grinning up at him as she pulled up for a moment, “Go ahead, Sun... be as loud as you want to. Nopony but me can hear you now, and I’d love to hear all of your feedback... and that’s an order.”

“Y-Yes, ma’am,” Sun said on reflex to a superior’s orders, watching Celestia looking down at the large, tasty stallionhood now glistening with her saliva.

She paused a moment before, sinking her muzzle down again, she soon enough reached his medial ring, earning an especially loud moan from that as she ringed her tongue’s tip around it.

Sun meanwhile had never felt such pleasure before, letting out a moan that was almost more of a cry of pleasure. Sure, his hooves or magic would get him off, that ‘magic vagina’ spell he’d learned being especially lovely, but none of that could even hope to compare to the blissful warmth surrounding him now; the beautiful pale-magenta eyes looking into his own as she slowly did for him something a spell could never duplicate, the gentle magic of the Princess of the Sun rubbing his testes and making his hips jerk up into her muzzle.

Celestia was only too glad to take the extra inch Sun gave her, grinning around his cock at his youthful eagerness. She could smell by his musk, and taste in his pre, that he was a very virile specimen. A perfect stud, and adorable too.

“O-Oh my gosh!” Sun whimpered out as Celestia took his entirety into her muzzle and throat, all the while cupping his dick’s underside with her tongue, him watching the gentle bulge he caused in her delicate neck as she swallowed around him before she soon after pulled back to breathe.

“Are you enjoying yourself, my handsome stud?” Celestia asked as she pulled off of him a moment later, using her hooves instead to slowly jack his member between them, earning a steady stream of pre-cum from him as she felt his cock pulsing in reaction.

The floor between Celestia’s legs was utterly soaked in her liquid lust, her tail flagged over her back and her clit constantly winking. Anypony in the doorway would have gotten quite a perfect view of that royal plot, though Celestia was certain nopony would disturb her at this time of night.

Celestia continued to jack Sun off slowly, before returning to using her mouth again, licking along his balls and taking one into her mouth for a moment before slowly licking along his sack’s seam, then following up his underside in a straight line until she reached his flare, before engulfing it entirely.

Sun felt the tell-tale pressure rising in his pelvis, his pleasure growing to its peak as he watched and felt Celestia more vigorously bobbing on him, feeling Celestia’s mouth growing tighter as his flare started to grow.

Celestia felt Sun’s hips matching her blow for blow, each quick drop of her muzzle over his cock met by him thrusting up, feeling his flare thickening in her muzzle – before suddenly stopping. Sun gave a displeased whimper as she did, feeling his body so close to its release yet denied.

“No, no... no you don’t Sun,” Celestia said teasingly, slowly shaking her head, “There’s only one hole that your most potent first ejaculation is going into, and it’s not my mouth... I think it’s about time we get to the main course.”

“B-buh what about you?” Sun asked, knowing very well that the mares usually got a turn in this, with the stallion returning the favor by stimulating them with their mouths as well after their mare pleased them if not before.

“I’m sure I’d love you returning what I did for you, but…” Celestia said, then winced as another intense surge of heated unpleasantness torched through her, “..but since I’m in heat, an orgasm without a stallion’s seed accompanying it would only aggravate my condition more. Maybe after you breed me you can return the favor. Speaking of...”

Sun then watched as Celestia turned around and presented her perfectly-rounded flank to him, all the sweets she’d eaten over the years having settled nicely and given her a shapely rump. Her tail was still raised over her back, her pussy still soaked and winking, and as she turned Sun got a powerful whiff of her fertile scent as her tail swished it towards him, his cock throbbing in reaction.

“...I think it’s time we do just that.”

Celestia finished, her slit facing him as it frequently winked while she looked back at him expectantly.

Once more, Sun was stunned. Every time he thought he’d wake up from a mischievous dream conjured by Princess Luna for him, he never would. Each time a twinge of pleasure or whiff of Celestia’s estrus would enter his muzzle, he could think a prank was being pulled on him while he dreamed, but the look in Celestia’s eyes told him she was all too serious; the longing in those magenta pools, the feelings rolling through him, were too real to be freigned for a joke.

“Are you ready?” Celestia asked, giving a big smile to hide her own nervousness at the prospect of becoming a mother; “Are you ready to make me a mother?”

Sun felt nervous butterflies dancing in his stomach as he saw Celestia presenting to him, his base instincts telling him to go, to mount the willing, fertile mare and plant his seed. As he stood, he saw Celestia’s tail hike just a bit higher, her watching as he approached her.

“Here... let me get on the bed. It will make things... easier for you,” Celestia said, knowing that stallions had trouble mounting her because of her always being taller than them.

Sun was no exception.

Sun nodded, then watched as Celestia lay on the bed, her forehooves folded beneath her and her rump high in the air, still displaying fully to her stud. Sun was beyond ready, his whole flare coated in his pre-cum and Celestia’s drying saliva, and as erect as he possibly could be.

“Come, Sun. Breed me!”

Sun couldn’t help himself as he climbed atop Celestia as his instincts demanded, giving quiet breeding whinnies to drive Celestia’s arousal even higher. As he felt her hot, sweaty back against his sensitive chest, her warmer temperature undoubtedly caused by her estrus, he heard a quiet moan from her, feeling her shudder in reaction to being mounted.

“Mmm, it has been awhile since I’ve had sex... and it has been much longer still since I’ve had a virgin share my bed…” Celestia said in a throaty voice, spreading her back legs wider to give her stallion a bigger target, “...and this position is the easiest for a stallion’s first time, plus it only seems appropriate to be bred in the way of my ancestors.”

Sun had all but zoned out at this point, the feeling of an in-heat mare beneath him, the scent of her pheromones flowing through his mind, all setting his hips into motion. Celestia gave a quiet ‘mmm’ as she felt his flare tapping against her rump, him draped over her.

“Sun?” Celestia asked.

Sun kept thrusting, trying to penetrate his mare on instinct.

“Sun... Sun!”

Finally, Sun stopped and looked at her with a confused, dazed expression, as though he hadn’t heard her before.

“I can tell you are eager, but once you inside of me, start slowly. We have all the time in the world and I want you to enjoy your first time, and neither of us can enjoy it if you are seeding me within twenty seconds because of overeagerness,” Celestia said, smiling at him, “After all, a stallion’s first time should indeed be special, as should be the time I am given my first foal.”

Getting out of his breeding haze, Sun nodded to his mate, before starting to thrust slowly, tapping all over Celestia’s rump. As he still hadn’t found his target after twenty seconds of seeking thrusts, the anticipation almost palpable from both, he was frustrated and nervous. He could tell Celestia was restless as well, squirming beneath him as her estrus burned especially hotly now that she was mounted.

“I’m sorry…” he said, half-fearing she’d view him as unworthy of being a sire if he couldn’t even properly mate her.

“It is alright, Sun. It is your first time, and this surely happens to most stallions,” Celestia said, reaching back to rub her muzzle against his comfortingly, “Would you like some help?”

Sun nodded, and quickly he felt a gentle tingle on his penis, the tell-tale feeling of magic on flesh, as well as it being moved. Soon, he felt something wet and incredibly warm rubbing against his flare, Celestia having guided him to where he needed to be. Before he could fully thrust into her on instinct, however, he felt himself still being held in place; being held back.

“Remember...start slowly, then you can speed up more once you are more used to how it feels,” Celestia said again, getting a series of nods from Sun, before then releasing her magical grip on him.

The foreign yet oddly familiar urge to push into that warmth overwhelmed Sun as he slid his hips forward before even consciously recognizing his actions, feeling Celestia’s nearly-hot insides sliding along his flare as it softly popped in, then immediately after the upper part of his spire followed. Sun’s head lulled back as he felt that comforting, satisfying warmth as he started sliding deeper, his hips driving him into his first mate.

Celestia, meanwhile, gave a contented hum as she felt herself being spread open, her entirety thrumming with pleasure as she was slowly filled by her rather large partner.

“Mmm, Sun, you’re so big… you feel so good…” Celestia praised, the words causing Sun to jerk his hips forward, making his mare moan happily as his thick medial ring went inside of her as well, rubbing her clit on its way in.

Sun moaned himself as his actions earned him a tight clench and a wink of the clit from her at the added sensations, Celestia smiling at the reaction too, “You’re doing perfectly, Sun. Just keep going in slowly.”

If not for the reminder, Sun would likely have started thrusting wildly, his instincts firing on all pistons now as he felt the warmth of a mare surrounding his most sensitive part.

“I-it feels... s-so good inside of you… r-really... hot,” Sun said with struggled words, the sensations along his penis almost overwhelming.

“Yes Sun, that is how the vagina of a fertile mare is. Warm to keep the male’s seed alive until one reaches her egg and fertilizes it,” Celestia said in a sensual tone, the thought of all of this making Sun shudder once more.

Sun was simply enraptured by the feeling of warmth and wetness surrounding his cock for the first time, pulses of strong sensation going through him with each squeeze of her extremely tight passage spasming on him. He felt as her insides seemingly form-fitted and gently rippled over his length, a small inner ring just past her entrance squeezing him tightly, as though it were tightly masturbating him inside of her.

Moments later, Sun had hilted in her, filling her entire passage with stallionhood. He held inside of her at that depth for a moment, savoring the feeling of being fully encased by a mare’s passage, before his hips started to pull back all on their own, then hilting himself again slowly as his medial ring exited, reigning in his instincts as his princess had asked him to before simply pounding her into the mattress.

“Mmm, good... now just keep doing that for now,” Celestia encouraged, reaching up to nuzzle him affectionately again.

She felt satisfied as she was spread so widely, a stallion once more within her and slowly claiming her, but she knew this time would be different. She’d be getting a foal from this one.

Celestia reached back and once more met her lips with the stallion slowly sliding in and out of her, admiring his restraint despite undoubtedly wanting to rut her with no regards to her pleasure.

“You’re doing perfect, my handsome stud. You may speed up a bit... just like that…” Celestia said as he sped up just a little, undoubtedly starting to cave to his instincts a little.

“Gooood!” Celestia moaned as his speed once more picked up, feeling her burning need now starting to be satisfied more, the slow, unsteady thrusts of her virgin mate turning into longer, smoother ones as his instincts guided him along his path to breeding his mare.

"You're so hot inside... in heat and your womb ready for my foal..." Sun whispered sensually, before getting impatient and pressing himself the rest of the way into her again, with it feeling as though they were made for each other, his flare sitting pressed gently against her dilated cervix and her passage form-fitting it perfectly; "It feels... amazing..."

Sun continued to work on instinct as he slowly humped into Celestia, pulling out partially so his medial ring exited her, before swiftly hilting himself again, being rewarded with a wink and a tight squeeze from her. He wasn't thinking about other ponies at the moment, nor the foal that would likely result from this as planned; he was simply thinking of the heated mare between his forehooves and beneath him, her foal-passage so delightfully, eagerly kneading his stallionhood of its seed soon to come. Sun simply kept up his slow but deep motions, before hearing her whisper for him to go a bit faster. So he did just that.

Sun kept his pace as steady as he could for the next minutes, the pleasure and Celestia’s contented moans distracting from that, increasing his urge to simply let loose and thrust rapidly, to reach his finish and seeding his mare. Still, he kept his pace moderate and even as Celestia had asked him, only slipping his medial ring in, and each time it grazed over her clit.

“You... can go faster now Sun. Please,” Celestia asked simply, her mind too abuzz with pleasure to manage much more, her estrus being quite satisfied with the male inside of her.

Sun indeed sped his thrusts upon request, his urges growing the same as his mate’s, and before long the already stimulated male felt himself reaching his end soon.

“C-Celestia, I... I feel it coming soon,” Sun warned, feeling Celestia continuing to expertly squeeze on him, her pleased moans becoming more desperate.

“I-I am ready too. Sun, plant your seed deep within me. You have pleased me well, now make sure to get as deep as you can to give me the best chance of getting your foal. Make me climax with you!” Celestia said, always motherly even on the cusp of her own orgasm.

She eagerly anticipated the warm, gooey sensation of a male’s seed entering her in her estrus, the relief it would bring as well as, this time, the child it would create.

“Make me a mother!”

The urge to finish, the deeply-seated urge to finish flared deep inside his fertile mate and having her permission to, was finally all Sun could take. He upped his thrusts to those rapid motions of a climaxing stallion, each thrust hilting him into his mate, feeling her cervix pressed to his glans with each one. He felt the tightness in his pelvis growing, his body tensing as he felt himself throbbing more and more rapidly in his mate, his flare swelling thickly to contain his seed when he climaxed.

Celestia felt her stallion flaring thickly in her, that feeling of her male preparing to inseminate her, to breed her, making her give a fully-bodied shudder of pleasure.

“I’m so close now, Sun. Please, let me finish… make me a mother,” Celestia whispered, Sun seeing that this princess, this virtual goddess of fertility, was but a simple mare beneath him – a mare with the same desire and need as every other mare in heat; the want to satisfy that burning within her belly and bring forth a new life unto themselves, a foal to love, teach and cherish.

As Sun felt his climax approaching rapidly, his pace became fervent, his balls making an audible slap with each rapid hilting he gave the princess, before it all came to its end as Celestia softly massaged his testes in her magic. Sun hilted himself as far as he could into his mate as he could on that hard-wired instinct, so his seed may enter as far into his mare as he could make it. He gave a deep breeding whinny as he felt himself pulsing, sitting fully-flared at the mouth of Celestia’s womb, ready to fill it full of everything that his virgin orgasm to a mare had to offer.

As Celestia felt that soothing warmth pulsing into her, Sun's flare heavily swollen and pressed up against her cervix and coaxing it to spread just a little more, her burning fire was extinguished as she felt each pulse of his cock along her passage. She cherished each spurt of his sperm-rich fluid going into her womb as she massaged everything she could from his testes with her magic; the seed of her foal, an heir to Equestria, being planted.

Celestia came hard with a whimper in reaction to her stallion’s warm cum spurting into her and his member throbbing rhythmically inside of her as he ground himself against her, her whole body trembling as her passage kneaded every virile sperm it could from him. A gush of her feminine fluids splashed back onto her mate, claiming him as hers, her mind awash at the satisfying warmth of a foal being pumped into her womb by a worthy sire.

Sun, meanwhile, felt as each shot of his foal-batter was milked from him by Celestia's tight contractions, his head down, biting into her crest on instinct like a feral stallion would to keep his mare in place as he felt each pump of his cock, each joined by an immeasurable surge of pleasure. Continuing to shoot his essence into Celestia's royal, mother-bound womb as she only too gladly accepted it.

It felt like minutes passed in Celestia's delusional state, feeling each throb of Sun within her and each spurt of satisfying warmth entering so deep into her belly, but he did not stop cumming, not until his body was sure his mare was with his foal.

Celestia felt the satisfaction of afterglow wash over her as she still held Sun tightly inside of her even after his pulsations stopped, her body not wanting to let its partner go, wanting to keep him deep inside of her until her egg was claimed by the seed so tightly packed into her womb. She shuddered as she felt just how much sticky, gooey warmth was inside of her, knowing she'd very likely be pregnant by day's end.

"Mmmm, that felt wonderful Sun..." Celestia cooed out, her whole body feeling utterly satisfied now, her heat long dead and drowned, "Thank you for agreeing to be the sire to my foal. Our foal."

Sun was somewhat surprised to feel Celestia’s lips once more meet his own as he stayed hilted within her, his cock softening even as he desperately tried to stay within her, until finally, it slid out with a wet schlick, followed by a small trail of semen.

“It was my pleasure, Celestia. Thank you for choosing me for such a wonderful honor,” Sun replied after the kiss ended, nuzzling into Celestia’s ethereal mane.

As Celestia felt semen oozing out of her at his absence, and not wanting to waste any of Sun’s potent foal-cream, she quickly used a rod of magic to push all of his semen from her passage deep into herself with a moan, before applying a small force-field spell to seal her cervix and prevent any from escaping. Sealing all of his virile seed into her lightly-swollen womb, surely guaranteeing her egg’s fertilization.

“I thank you for this Sun, and do not fear, this is not the end of us. It is only the beginning,” Celestia said with a smile, but then she lost that smile and her voice took a more somber tone, “Of course, we should keep our love secret, if only for now. Again, a princess sleeping with her guard could cause problems with the nobles, so until the foal is born, we should keep our relationship in private. Fret not, however. I will never turn you away from my chambers at night, whether simply to keep each other company or to make love.”

Sun understood and nodded, for his mind now still fuzzy with endorphins of his release and the pride of completing his deepest calling of reproduction.

“I understand, your highness. It is my honor to be with you at all in this way, whether in secret or public. I would be proud to call you my mare-friend.” Sun said, getting a large smile from Celestia.

“...and I would be proud to call you my stallion, in time,” Celestia said, nuzzling back, feeling a strong urge to be close to her stallion now.

As she felt a dimmer flame forming in her, her heat resurfacing, Celestia gave a small groan of discomfort.

“Sun, would you want to return the favor of what I had done for you earlier, before our mating?” Celestia asked, seeing Sun’s eyes go slightly wider at the implications.

“Celestia, it would be my honor to... perform oral on you… it’s just...” Sun said with some reticence at having to eat his own seed, earning a soft chuckle from his broodmare as she squirmed away from him and lay on her back, with Sun positioning himself behind her.

“Worry not, I have pushed everything from my passage into my womb. There will be nothing there but my fluids,” Celestia promised, before something else came to mind. “After you ‘eat me out’, perhaps you should stud me again, just to make sure your seed takes? I have no doubt I shall carry your foal by the end of this day, but being positive surely is no problem, yes?”

“No problem at all my mare, no problem at all,” Sun promised, before giving a firm lick from the base of Celestia’s slit to her winking clit, tasting nothing but mare, meanwhile eagerly anticipating his chance to once more mount and give his seed to this beautiful, lovely mate once more.

Chapter Two: Many Months Past

Something has gone wrong. We don't seem to have an archived copy of that chapter.

Epilogue: Children of the Night

Epilogue: Children of the Night

Epilogue: Children of the Night

As the graceful, silver glow of the glamorous moonlight shone in through the tall windows of her grand bedchamber, Princess Celestia lay on her bed miserable and exhausted yet unbearably tense, covers lying scattered about her as she cradled her large pregnant belly gently in her forehooves. It had been almost seven months now since she'd gotten pregnant and as she began nearing the end of her term, her belly was only growing far larger every day.

Soon she'd be going through the whole ordeal her sister had gone through two months ago, although unlike her sister she'd have a full team of the country's best doctors to help deliver her foal. The little one within her womb kicked and squirmed as she thought about that, almost as if they were happy that they'd be getting such royal treatment. Still, that wasn't to say Luna's foals, her niece, and nephew, were any worse off for having been delivered by Celestia herself really.

Celestia had been alive for over a thousand years, and in all that time she'd been a midwife to the delivery of her fair share of foals, albeit by accident or not. In fact, when it came time to deliver her sister’s offspring that night in her room, she wouldn’t have really trusted anypony other than herself to bring them into the world. As she’d seen them for the first time that night, indeed the first pony to ever see them, she still remembered to this day how both of the foals were absolutely beautiful.

The filly, whom Luna had named Aurora, was a small bat-pony filly who was almost a spitting image of her mother save the tufted ears, golden-yellow eye color, small fangs and slitted pupils from her father, her mane a mid-blue to match her deep-blue coat. As she’d seen her horn as well as wings, Celestia knew that her niece was also the second natural alicorn birth Celestia had ever heard of, her adoptive niece Flurry Heart being the first, and that Luna had gotten what she’d desired: a powerful defender of Equestria.

The only oddity was Aurora’s leathery bat wings rather than the traditional feathered Pegasus ones, undoubtedly inherited from her father alongside her eyes and ears. Those thestral traits would surely raise more than a few questions if she was ever discovered. For her very young age of only months old, she spoke with a wisdom beyond her years, surely an old soul in the vein of her mother. More often than once, Celestia had come into the foals’ nursery to see Aurora simply sitting there in a way no other filly would at only several months old, and when asked what she was doing, she would only reply that she was ‘thinking’. She had definitely taken that after Luna’s sage, philosophical personality, and likely also inherited her tendency to be brooding as well.

The second of Luna's twins was a little colt named Nocturne. A healthy little prince, he too was a bat-pony, though not an alicorn like his sister, having the wings of a thestral but no horn. His coat was a handsome shade of blue-grey, his mane a deep midnight-blue, and his eyes the beautiful blue of his mother’s but slitted like his father’s, as well as having a small pair of thestral fangs. He was far more playful and silly than his more stoic sister, acting like a colt should, trotting around with youthful exuberance and more than once making his mother and aunt laugh at his antics.

Celestia still remembering the night they were born fondly as she lay in bed, had remembered that the second-born colt had also been larger than his sister and pushing him out had caused more than a little discomfort for Luna that night months ago, though the complete joy and bliss on Luna’s face when she’d finally held her children in her arms was nigh incomparable to anything Celestia had seen in her life.

Still, it was more than evident now how much Luna loved both of her foals, perhaps even more than she had said as she’d been carrying them, as every evening before raising the moon, she'd tuck them both into their bassinette and sing to them. Add to fact that Celestia was one of only two ponies to know of their existence, and was needed to help tend to almost their every need despite being pregnant herself.

Still, it was a horrible shame that Luna still insisted on keeping the beautiful new prince and princess a secret, especially from their father. Dusk Hunter, their sire, was stationed right here in the castle and, because of what Celestia viewed as Luna's stupid desire to have secret guardians of Equestria, he could never know that those two adorable, sweet little foals were his own; that he was a father.

Once or twice Celestia had thought to tell him he was a father herself, and had asked Luna to at least let her foals’ fathers know of them, but Luna, with a heavy heart, still stubbornly insisted on secrecy despite seeing Dusk every day and acting like nothing had happened between them. Celestia knew that Luna had trusted her with his identity, that she couldn't betray her sister like that. It was Luna's right to tell him or not in the end, no matter what Celestia thought.

At that thought, Celestia rolled over, grumbling slightly at the cramp in her gut as her little foal kicked up a storm in its shrinking temporary home. Resting on her side she looked down at her distended belly, rubbing it once again.

"Sorry little one, but mommy has to get up soon. You're really laying hard on her bladder." Celestia said to the restless mass, but as if in defiance of the statement, it only began to wriggle more.

"Ooof, all night, huh?" Celestia groaned, pressing a hoof to the mass, and feeling another smaller hoof kick against it almost instantly, unable to help cracking a grin; "Haha, there you are my little one!"

After getting up and relieving herself of her bladder’s burden, Celestia then whimsically began to try and sooth her boisterous foal, before she was caught off-guard as the doors to her chamber opened and somepony slid in. Celestia recalled that she was not supposed to be disturbed during the night; then again, when had that ever stopped Equestria from being in danger before? All she could think was that this had better be important.

Struggling to sit up, and grunting as her swollen bump fell between her legs, Celestia looked about her room and almost instantly came eye to eye with her little sister. Luna looked very tired, not to mention the extra weight she'd gained while carrying the twins was still rather evident now that the large pregnant belly wasn’t there to distract from it. Even so, with the amount of running around after the foals, especially with Aurora and her alicorn magic outbursts, Luna was sure to burn that off in time.

Still, Celestia wondered what her sister was doing her in the middle of the night though and intended to find out just that.

"Oh, Luna… I… I wasn't expecting to see you here," Celestia stated in surprise, but all Luna did in response was look about the darkened room cautiously.

"Do forgive the intrusion sister, but...may I ask...is thine beau Sun Strike around?" Luna asked, eyes still darting about the room.

"Why no, he's stationed on the outer wall tonight. He will not be back until morning and then I assume he will wish to rest...why do you ask Luna?” Celestia responded skeptically, not being able to read her sister’s intentions just yet.

At the confirmation that Celestia’s mate and the father of her sister’s foal was indeed not here, Luna began to creep forwards. "Well, I was thinking...today was the first day that I was able to get both of the twins to sleep on time. They’re both absolutely exhausted after I took them out flying. Plus, Aurora nearly broke the invisibility illusion I cast on us all with a giant surge of uncontrolled magic caused by sneezing, and that took a lot out of her." Luna said as she crept right up to Celestia, pushing until Celestia was forced back into the bed with a soft puff of the covers and mattress.

"I was thinking that, while I have some scant free time now for the first time in what feels like forever, that we..." Luna's muzzle curled into a sly smile, and as Celestia regarded her she felt an uneasy twitch in her bloated stomach.

"...that we may finish what we started the night I had the foals… you know, consider you never really got anything other than a face full of my various fluids, and a lot of my kicking and screaming for it to all end." Luna finished with a blush.

"Oh, and how do you plan to do that? I recall one of the major factors of that evening was the fact you were still full of foals and I found that sexy?" Celestia mused, but Luna only smiled.

"True, ‘Tia, true…but now I can move again I can please you in a different way. Plus, you're still very much with a foal after all," Luna added, slowly rubbing a hoof over Celestia's quivering belly and ushering a heated shudder from the larger alicorn, “...and that is indeed very sexy.

At such a response, Luna's sly grin grew wider as her horn began to glow, and from behind her back levitated up a very large strap-on dildo, as well as a ball gag.

"So, ‘Tia, do you want to see what it feels like to be filled with a cock and foals at the same time...by your sister? If you like it, then I don't know…maybe one day you could return the favor.” Luna mused, meanwhile sliding the dildo’s harness over her own pelvis as she received a small nod of consent from her sister, “I mean, who says we have to stop at just one pregnancy? I think I could be pregnant all the time, filled up to bursting, then giving birth to more and more foals of our royal blood!" Luna stated, resting her head on her sister's belly and stroking it like it was some kind of precious pile of gold, meanwhile using her magic to softly rub along her older sister’s folds with the tip of the pseudo-phallus.

“After all, aren’t royal families traditionally very large? The royals of old used to sire or give birth to tens of foals, so why shouldn’t we?”

"Oh, Luna..." Celestia said, smiling wryly, "...you can fill me up with that as much as you want any day, and right now I think you owe me as much as you can give for what I did for you that night. Hay, maybe one day I’ll even invite Sun to join us. I’m positive he wouldn’t mind bedding two princesses" she said, spreading her back legs wide in invitation.

“I would like that sister, very much. It has been far too long since I’ve been with a real stallin. Who knows, perhaps he could even sire my next foal as well!” Luna said, grinning as she mounted her sister.

Celestia smiled, nodding a little at the thought of watching her sister getting impregnated by her colt-friend, but that was all for a later time, after she gave birth to her foal no doubt. Perhaps tonight would be a good night after all, Celestia thought, smiling as she felt the tip of the dildo slide into her, and her sister’s loving kisses on her muzzle.
