Chapter 1

“Well, well!” chuckled Celestia. “Twilight Sparkle, behind schedule! I never thought I’d see the day.”

Luna - grinning just as widely as her sister - rested her chin on her interlaced fingers, and used her magic to levitate place settings over to Twilight’s seat. Teacup, saucer, teaspoon, and sugar bowl all set themselves down in perfect arrangement. “If your brilliant student is late,” said Luna, “It can only mean she was attending to matters of paramount importance. Please, Twilight Sparkle, take a seat and tell us what kept you.”

Twilight closed the tearoom’s door behind her, meeting the eyes of her two royal lovers. She was more accustomed than most to the presence of the royal sisters, but there was something freshly intimidating about the way they looked at her lately. Ever since they'd started formally dating a couple months back, the princesses’ love and admiration were undisguised - even when they were gently teasing her, as they were now. Being loved by the two most powerful ponies in Equestria was still overwhelming, and Twilight was never quite sure that she was enough mare for both of them.

But today she came with good news, and that fact buoyed her self-confidence. She took a seat between the two other princesses and got her thoughts in order, preparing to bring her lovers up to speed.

“Sorry to be late,” said Twilight, “but Doctor Cycle had an earlier appointment that ran long, and I didn't want to interrupt her…”

“Oh, Twilight,” said Celestia, using her magic to lift the teapot and fill Twilight’s cup, “you must get into the habit of throwing your royal weight around. You know - insisting that ponies drop everything for your sake, bellowing in the Royal Canterlot Voice when you don't get what you want… Luna, back me up here.”

“Oh, yes,” said Luna. “I can't recommend it highly enough.”

Twilight blushed, suppressing a grin. Her lovers really couldn't get enough of teasing her - and who could blame them, when she always gave them the reactions they were fishing for? “Even if I wanted to, er, assert royal privilege,” she said, “I was in disguise. We haven't discussed how public we want to make this yet.”

“Hm, sensible as always,” said Celestia. “So - what news?”

“The news is good!” said Twilight. “Doctor Cycle says my sperm are healthy, viable, and in all respects normal - aside from the fact that they come from magical testicles that don’t exist most of the time. I had her run every test you can, and the results were all good.”

“Well, there’s still one more test of your potency,” said Luna, running her hand along Twilight’s inner thigh, “and I’m looking forward to being a part of it.”

Luna’s overtly sexual gesture sent a shiver through Twilight’s body - and although she didn’t have a cock at the moment, she couldn’t help but imagine herself getting hard at the sight. As arousal spread through her body, she snapped into a different frame of mind - all of a sudden she wasn’t the anxious Twilight Sparkle who got teased by her immortal lovers. She was the dominant, big-dicked princess who fucked the royal sisters whenever she wished. “Can’t wait to be my broodmare?” she asked, licking her lips and gazing seductively at Princess Luna. “Oof, I could load up your belly with a big litter of foals, Luna…” She turned, eyeing up Celestia's midsection. “You too, Celestia… you'll be gorgeous when you're in the full bloom of motherhood, bearing all my little ones…”

Now it was Luna and Celestia’s turn to blush. Celestia took a deep breath - which made her chest rise alluringly - and steadied herself before responding. She could have stripped herself down then and there, begging to be fucked - but there were practical matters to think about.

“On the subject of, er, breeding,” said Celestia, “we should discuss precisely how many children we intend to have. Fantasies of growing immensely heavy with child are all well and good, but how many children do we actually intend on raising?”

Twilight’s mind, faced with a practical question, downshifted into analytical mode. “Well, we’re all busy mares,” she said, “and I don't expect that will change. Of course, some tasks can be delegated, and we can hire on nannies to help with child care.”

“Celestia and I have been discussing this matter between ourselves,” said Luna. “We believe the ideal number would be six; two children for each mother shouldn’t overtax us.”

“Especially if we space the pregnancies out over several years,” agreed Celestia. “If you were drooling over any hyper-potency enchantments, then I hate to be a wet blanket - but a conventional impregnation for each of us will be fine for now.”

Twilight let out a little snorting laugh. “I don’t know if I can do a ‘conventional’ impregnation,” she said. “Would you settle for a hard, passionate fucking that leaves you aching with pleasure?”

“That sounds like a very agreeable compromise,” said Celestia, demurely taking a sip of her tea.

“So we’re good to go, sperm-wise,” said Twilight, “but I've been researching pregnancy too! The data says that the most common cause of miscarriage and pregnancy complications is the embryo implanting in the uterine wall in an odd location.”

“My, this conversation took a rather sudden swerve in a much less sexy direction, didn't it?” said Luna. Celestia gave her a gently scolding look, and Luna waved it away. “Oh, I'm only teasing,” she said. “Go on, Twilight.”

“There's a spell in the medical literature,” said Twilight, “that a mother can cast during conception to guide the fertilized egg to an ideal position. The only problem is, it’s difficult to know exactly when the egg is released…”

“But there’s another spell,” said Twilight, “that permits the mother to control the release of her egg. Cast together, these two spells practically guarantee a successful pregnancy! They're rarely recommended, though; for one thing, it has to be the mother who casts them, which obviously rules out pegasi and earth ponies. And even for unicorn mothers, the second spell is particularly difficult - and casting it improperly would make complications a lot more likely.”

“I see,” said Luna. “Celestia and I should be able to cast both spells easily enough, after a bit of study… and then it's smooth sailing until we bear your foals.”

“Well, I can't guarantee ‘smooth sailing,’” said Twilight, “but I've done my best to remove every obstacle I can.” With a flash of magic, she manifested two rolled-up sheets of paper and set one down in front of each princess. “I’ve got the spells copied down here,” she said. “You’ll need to learn them both, of course, if you think this is a good idea.”

Celestia smiled warmly at Twilight, amusement tugging the corners of her mouth ever upwards. Of course her former student had covered every angle. How could she expect any less?

“It seems that you've thought of just about everything, Twilight Sparkle,” said Celestia. “But there's a single, solitary detail you overlooked.”

“Really?” said Twilight, tapping thoughtfully at her chin. “I really thought I’d considered everything…”

Luna raised a hand to her face, hiding a secretive smile. “Well, it’s not strictly required,” she said. “But there’s one step you usually take before getting a mare pregnant, if you wish to avoid scandal…”

Twilight took a moment to think, running through the process of impregnation from start to finish… but she couldn’t think of anything she’d overlooked. She met Luna’s eyes again, and noticed her hand in front of her mouth - its bare, splayed blue fingers…

Twilight gasped, her lavender body turning beet red. The air snapped as she teleported away - and Celestia and Luna only had a moment to share a giggle before she returned, holding a ring-sized box in each hand.

“Would you-” gasped Twilight, looking back and forth between the royal sisters. “Would, uh… both of you like to- would you be my-”

Celestia and Luna wanted to say “yes,” but they couldn’t stop themselves from laughing.

Any average pony who found their way into the realm of dreams would be likely to end up hopelessly lost, tumbling between minds, hurled out into the howling darkness each time they made a wrong turn. The setting of the moon would eject them - mercifully - and their heads would be swirling with senseless memories of impossible spaces.

But Nightmare Moon was quite at home in this space. It wasn’t just that she was powerful; she also had millennia of practice when it came to finding the easiest path between one dream and another.

Tonight, the traversal was simple indeed. Leaving Twilight’s dream and entering Celestia's was as easy as walking through a door; their minds were joined by love and years of bonding, which made their dreams cling together like two soap bubbles. Nightmare Moon pushed through the golden door to Celestia’s mind, and found herself inside a castle of pure white marble, red pillars, and golden trim.

This castle’s purpose was to exalt the mare known as Daybreaker, the fearsome ruler of Equestria. The only ruler of Equestria, in this dreamworld. Perhaps Nightmare Moon should have been offended that she had no place in Daybreaker’s perfect world - but that would be a little hypocritical, wouldn't it?

As the dark mare walked the halls of Daybreaker's castle, she couldn’t help but admire the regal portraits and immense golden statues she passed by. The first few depicted Daybreaker as a ruthless conqueror; there were paintings of her standing triumphant over ravaged battlefields, and ten-foot-tall statues depicting her holding aloft a flaming sword.

As Nightmare Moon drew closer to the throne room, she began to see more intimate depictions. Twilight Sparkle began to appear at Daybreaker’s side, clinging to the flaming mare or gazing adoringly at her brilliance. Notably, Twilight was was always depicted with a prominent bulge in her crotch; no matter what she was wearing, it clung to her stallionhood in such a way that her thick shaft and hefty scrotum were on proud display.

And by the time the throne room’s doors were in sight, the hallways had turned to a gallery of outright pornography. The paintings depicted Twilight penetrating Daybreaker in the bedroom, on the throne, on a hill overlooking a ravaged battlefield… And the golden statues presented Daybreaker with a colossally pregnant belly. She took obvious pride in the size of her baby bump, although it was an unconventional look for a conquering royal.

When Nightmare Moon reached the throne room’s doors, she swung them open and found Daybreaker on the throne - seemingly doing nothing in particular. “Hello, sister,” said Daybreaker. “I’ve been expecting you. I can always tell when you're planning something, even if it escapes Celestia's notice.”

“Oh, I would scarcely say I was planning anything,” said Nightmare Moon, feigning an air of modesty that suited her very poorly. “I thought I'd come by and congratulate you on your engagement to Twilight Sparkle.”

“The same to you,” said Daybreaker. “Although with everything that's been on Twilight’s mind, I worry that she doesn't even realize that she's engaged to us as well.” She smiled, and her mane rippled with a surge of heat. “We’ll need to remind her of that.”

“I’m sure she hasn't considered that you will be the mother of her children, alongside Celestia,” said Nightmare Moon, with a cruel little smirk. “Lucky for you. If she pictured you trying to look after a child, I think she would reconsider the whole arrangement.”

Daybreaker snorted. “You imagine that you are better suited to childrearing? I anticipate that Luna will keep you on a very short leash after the foals are born, lest they grow up to be as morose and jealous as Nightmare Moon. Even one child would grow bored of you very quickly, sister; it is the height of hubris to imagine you could keep six foals entertained.”

“And you think Twilight would entrust her goals to someone so self-absorbed?” spat Nightmare Moon. You'd barely notice if all six of them toddled off into a timberwolf’s den. I could manage a litter three times that size.”

“That boast rings rather hollow,” said Daybreaker, “since the princesses have agreed on six children, and no more. For all her talk of breeding and swollen bellies, Twilight is ultimately a very sensible mare.”

Nightmare Moon chuckled, and Daybreaker fixed her with a quizzical look. “Ah, sister,” said Nightmare Moon, “you think yourself to be Twilight's perfect match, but your knowledge of her heart ends in the waking world. I see her dreams, Daybreaker, and they provide me with delectable insights into her secret heart…”

“You've been spying on Twilight’s dreams?” asked Daybreaker. “Odd, I don't recall you asking for her permission.”

“Oh, come off it, sister,” said Nightmare Moon. “If you had the power to enter her dreams, would you bother asking her permission? And besides, I only did it tonight; I believe our engagement gives me implicit permission to know my beloved a little better.”

“I suppose,” sighed Daybreaker. “So your little jaunt gave you… insights?”

“They did indeed,” said Nightmare Moon. “Today, Twilight shared her research and made plans for a sensibly sized brood… but in her dreams she was promising to make Celestia and Luna into proper broodmares as she filled them with huge, gloriously potent loads. She dreamed of our bellies swelling up with foals at the very moment of conception… ooh, how we moaned with delight, struggling to lift our tremendously burdened bodies. That is what Twilight truly desires… and we have the power to give it to her.”

“You paint an appealing picture,” said Daybreaker. “So how do we help Twilight?”

“While Luna was studying the spells Twilight gave us,” said Nightmare Moon, “I studied them as well, paying particular attention to the ways that they could be… exploited. I determined that, with a bit of clever manipulation, the spells could be used to release and implant multiple eggs at once. We can secretly increase the number of foals, and become the gorgeous, gravid broodmares that Twilight desires.”

Daybreaker squirmed in her throne, rubbing her powerful, snow-white thighs together. “Oh, sister, I love it,” she said. “Even our counterparts won’t know what we’ve done until they are already large with child… and by then, they’ll be just as delighted as us to see their fantasies realized.”

“I quite agree,” said Nightmare Moon. “It is a tragic waste for mares as powerful as Celestia and Luna to deny their desires. They are living gods, striding over Equestria, and they should be bold enough to give themselves whatever they wish for. Especially when doing so would make their beloved Twilight so happy.”

“The royal sisters are fortunate to have us,” agreed Daybreaker. “Without us, they would be prisoners of their inhibitions, forever compromising their desires with that which they deem ‘sensible.’” She laughed confidently - but then her expression abruptly fell. “Sister,” she said, “I hate to bring this up, but… boastfulness aside, are we truly certain that we can care for great numbers of foals? The princesses seemed to take the question very seriously.”

Nightmare Moon scoffed. “I would not worry,” she said. “The princesses made an error when they settled on six foals for three mothers. They did not include us in their count, did they?”

“You make an excellent point,” said Daybreaker. “And of course the numbers should be adjusted for the two of us; with our unrestrained power, we can handle far more foals than Luna or Celestia alone.” She stood from her throne, her mane blazing and her head held high. “Very well, sister - when Celestia studies the spells Twilight provided, I will study them as well - and together, we shall become the big, heavy broodmares that Twilight Sparkle truly desires.”

Chapter 2

“I know I should try and relax,” said Princess Luna, smoothing her dress as she sat on the edge of the wide, soft bed. “This is hardly the greatest challenge I have personally undertaken. It's silly of me to be so anxious, isn't it?”

“Terribly silly, Lulu,” says Celestia, examining herself in the mirror above the bedroom’s dresser. “You are a very silly mare, I'm afraid.”

Luna tossed a pillow at her sister, and Celestia allowed it to hit her in the back. “Perhaps you could support your sister in her moment of emotional vulnerability? For a change?”

Celestia sighed. “Luna, our wife has made every preparation, and we have limitless chances to re-attempt conception if it does not succeed this evening. There is no pressure upon you! Simply let Twilight Sparkle penetrate you with her long, lovely cock and fill you with her seed. Let this be enjoyable, even if it is also… pragmatic.”

Luna absorbed Celestia‘s words. “Hmm,” she said, “Very compassionate, Tia. Very supportive. Not bad for a first try.”

“Oh, and don't forget to cast a very complex spell while you're getting fucked,” said Celestia, turning away from the mirror to face her sister, “because if you screw that part up, you will ruin absolutely everything.”

Luna was brewing up a sufficiently acidic response when the bedroom door opened and Twilight Sparkle stepped inside. “Ready, girls?” she said, leaning on the doorframe and surveying the room with a sultry look.

“Oh, my,” said Celestia, putting her hand to her breast. “Is this the lovely, potent mare who’s going to breed us?”

“I believe it is, sister,” said Luna, rising from the bed. “That dress hides a thick, powerful stallionhood that with which she will consummate our marriage and make us heavy with child.”

“Oh, uh, actually,” says Twilight, her sultry facade falling, “I didn't give myself the penis yet… I can do that now, if you want…”

“It's quite all right,” said Celestia. “We’ll take the evening at our own pace.” She stepped over to the bed, standing beside her sister, and brushed the straps of her dress off her shoulders. “Just come to bed, my darling.”

Twilight joined them at the bedside, nervously tugging at the neckline of her dress. “I guess the sexy act didn't last long, huh?” she laughed. “I'm sorry. I want this to be fun, but I also want it to work, and… well, you know me. I'm not great at getting out of my own head.” She paused, chuckling. “Maybe I need a sexy, quasi-evil alter ego.”

“They're a bit of a mixed bag,” said Celestia wryly. “And don’t worry, Twilight - any evening with you is a treasure, doubly so if the evening is spent getting fucked by that lovely cock of yours. And if this particular evening is focused a bit more on conception and a bit less on fun, there is no place I would rather be, and no mare I would rather be with.”

Luna frowned slightly. “I was about to say something quite similar,” she said, “but my sister expressed the same sentiments well enough.” She clapped her hands purposefully, and in the same moment she magicked her clothes off her body. “If you have lingering worries, Twilight, then permit me to ease them.”

Luna, now bare, put a hand on Twilight’s shoulder and pulled her into an embrace. Their lips met, and Luna’s fingers slid down Twilight’s back, finding their way to her rump. As they kissed, Luna’s horn flashed and Twilight’s dress vanished, leaving the moon princess free to grope her wife’s bare bottom.

Luna guided Twilight Sparkle onto the bed, laying herself down with Twilight atop her. Luna grasped at Twilight’s soft round bottom with both hands, pouring heat and passion into the kiss, pulling Twilight deeper into her embrace.

Twilight felt another pair of hands on her back, then a pair of lips kissing the back of her neck. Princess Celestia embraced her from behind, tracing her fingers along Twilight’s hips and letting them drift upwards until they found her breasts. Twilight was sandwiched between the princesses - her wives - surrounded by their warmth and the scent of their skin. Her heart pounded - and she felt the pulse in her marehood, making the lavender lips blossom.

Princess Luna’s hand glided around Twilight Sparkle’s hips, discovering the wetness at the intersection of her thighs. Her fingers spent a moment there, probing her folds, drawing little moans from the Princess of Friendship, but Luna wasn't satisfied with that for long. She knew she wouldn't be spending much time with Twilight’s pussy this evening, and she wanted to make the most of the time she had.

Luna pulled back from the kiss and wriggled downward, putting herself face to face with Twilight’s marehood. Once again wrapping her fingers around Twilight’s asscheeks, Luna touched her tongue to Twilight’s pussy lips. She circled Twilight’s cunt with the tip of her tongue, holding her hips steady as the lavender mare began to buck.

“Luna,” gasped Twilight, “oh… ahh, Luna…”

Twilight felt Celestia’s hands leave her body - and a moment later, she was staring into the marble-white hips and glistening pink pussy of the sun princess. “Forgive me, dear, but it's awfully hard to get properly excited when you're just moaning my sister’s name. Let us put your tongue to better use, shall we?”

Twilight didn't need to be told twice. Princess Celestia's pussy had been a central fixture of her fantasies for most of her life, and the real thing exceeded anything she could have imagined. She dove in, eating Celestia's pussy with just as much vigor as Luna was bringing to hers.

But Twilight had a responsibility to both her wives - especially tonight - and the high-strung mare couldn't properly enjoy herself unless she was doing everything that was expected of her. She manifested a magical hand in front of Luna’s crotch, and sent its fingers exploring between her thighs. Luna gasped as the unexpected touch - but it took no time at all to discover its source, and then her mouth was back to work on Twilight’s pussy.

“It looks like we are all taken care of,” said Celestia, weaving her fingers into Twilight’s hair and stroking her behind the ears. “Ah, Twilight… as always, you are a devoted lover… my sister and I truly could not have asked for a better wife…” She pulled Twilight closer, wrapping her thighs around the lavender mare’s head. “I wonder, Twilight Sparkle, how long have you loved me? When did you first dream of diving between these milky white thighs and tasting my royal pussy?”

Twilight responded by vigorously lashing Celestia’s clit with the tip of her tongue - which was answer enough for Celestia. “Ooh, my most faithful student,” she sighed, “My darling, devoted wife… this pussy is all yours… yours to taste, to fuck, and to breed… I can hardly wait to feel that magnificent cock of yours, deep and hard within me, thrusting and throbbing and erupting with a potent batch of seed… Oh, Twilight, can you imagine it? How it will feel to hammer your long, powerful cock into my marehood… to feel it build towards climax… and know that your seed is gloriously potent…”

Celestia’s words filled Twilight’s pussy with an insistent heat, making her body shudder as she raced towards climax. She balled her fist, struggling to maintain her focus on the magical hand that was probing Luna’s pussy. She pressed the knuckle of one spectral finger against Luna’s clit, and willed the hand to vibrate forcefully against the glistening pink nub. Luna groaned in pleasure, lavishing affection on Twilight’s cunt, licking up and down her slit. She was losing control, moaning into Twilight’s pussy, her legs shuddering and her toes curling - and when she climaxed, she grasped Twilight’s bottom and lapped passionately at her clit.

Twilight ground her hips against Luna’s moaning mouth, quivering helplessly as Luna’s tongue went wild on her clit. There was no technique to what Luna was doing, just naked desire - but Twilight was so close that it hardly mattered. Twilight’s pussy clenched, pouring with nectar that spilled over Luna’s open mouth.

“Oh, Twilight, you lucky girl,” moaned Princess Celestia, “my sister is so good to you, isn’t she? She adores you, Twilight, she adores your pussy… and if she’s like me, she wants your big purple cock more than anything else in this world.” Her hips bucked, and Twilight’s tongue probed deeper into her cunt.

“But you can't fuck me,” said Celestia, “until you make me cum. Ahh, your tongue, Twilight… get my pussy good and ready, good and wet, make me cum, Twilight S-Sparkle…”

Princess Celestia came, and Twilight lapped up the nectar that spilled from the sun princess’ divine cunt. She licked it from Celestia's thighs, washing the alabaster skin clean with long motions of her tongue. When there was nothing left to lick up, she fell limp, joining her wives in the tangle of panting bodies.

But Twilight’s strength returned quickly - and her wives, who shared her royal stamina, also recovered within moments. Celestia and Luna sat up on the bed, watching Twilight expectantly. Twilight could feel their eyes on her crotch, staring into the empty space that her cock would fill.

“All right, girls,” said Twilight, licking her lips and putting on a confident smile. “I know that look. Those are the hungry eyes and drooling smiles of a couple princesses that are desperate to get fucked.”

Twilight drew in a long breath and focused power in her horn, recalling the spell that would allow her to impregnate the royal sisters. She didn't just need a big, hard cock this time; she needed a cock that came loaded with fertile seed. As her new stallionhood stretched and grew from her crotch, she shut her eyes tight and focused her mind on her balls. She pictured a swirl of thick white cum, loaded with tiny swimming sperm…

Her balls swelled to the size of oranges, and her cock stretched upwards until the flared tip brushed against the underside of her tits. When she felt herself stop growing, Twilight opened her eyes, expecting an appreciative reaction from Celestia and Luna…

But Celestia and Luna weren't there. Well, they were, in a manner of speaking, but a great deal had changed while Twilight’s eyes were closed. The supple curves of the royal sisters’ bodies had been replaced by powerful, toned muscles. Their gently waving, ethereal hair had changed: one had a mane of licking flame, the other of billowing darkness. And their eager smiles had become toothy grins, brimming with fierce, fiery lust. Nightmare Moon and Daybreaker were here, and they were here to fuck.

Daybreaker was the first to make a move, throwing herself at Twilight and wrapping her arms around her. Twilight, still adjusting to the sight of the princesses’ alter egos, was caught completely off guard, squeezed tight within Daybreaker's powerful arms. Daybreaker’s lips surrounded Twilight’s, and her tongue invaded Twilight’s defenseless mouth. Celestia's “darker half” must have been boiling over with desire, barely contained in Celestia's mind - and now that she was free, all that burning passion was flowing into that kiss.

Daybreaker pulled back and released Twilight from her embrace, grinning broadly when she saw how her kiss had stunned Twilight into silence. Nightmare Moon took advantage of her vulnerability, grasping Twilight’s scrotum and dipping her head to inhale its fragrance. “Ahh, that musk!” she growled. “The stallionhood of a lovely mare is a delight to all the senses. Perhaps it is my imagination, my love, but I feel as though I can smell the potency of your cum…”

Daybreaker wrapped her fingers around the head of Twilight’s cock, rubbing her thumb over the slit - and the combined affection of the beautiful, powerful princesses made Twilight feel as though she could erupt already.

“Twilight Sparkle,” said Daybreaker, “you must fuck me with this proud, towering cock… you must fill me with a huge and powerful load, and give me your foals…” she leaned down and gave Twilight's cock a kiss just below the flared head. “Oh, I wish I could taste it, my love… feel its warmth glazing my tits… let it splatter over my bottom… but my cunt needs everything you can give me.”

Twilight centered herself, forcing down her arousal in spite of the princesses’ affections. “Girls,” she sighed, “you're not really supposed to be here tonight. I'm trying to get my wives pregnant.”

“We are your wives, Twilight,” said Daybreaker. “I was forced to agree that emerging in the middle of the wedding ceremony would be poor form, but you married me as well as Celestia. And if you are going to breed Celestia, you may as well fuck the bigger, sexier version of her.”

“And besides, Twilight,” said Nightmare Moon, giving both of Twilight's nuts a firm squeeze, “it is not as though Celestia and Luna are missing out. They are not as separate from us as it sometimes appears; tomorrow, they shall remember the fun we had together. And those memories will be all the better, since they will remember being their greater, sexier selves.”

“Okay, but…” Twilight sighed. “Tonight isn't really about fun, you know? We're trying to get you girls pregnant. If you're looking for something buck wild, you might want to sit this one out.”

Daybreaker slid her hand down Twilight’s shaft. “The knowledge that we are to be bred by our beautiful wife is excitement enough. If it means bearing your foals, we can put up with an evening that is... less than utterly mindblowing.”

“And the spells?” asked Twilight. “Celestia and Luna won't be happy if you botch the fertility spells they took the time to learn. And neither will I, to be frank.”

“I swear to you, my love,” said Nightmare Moon, “we know the spells every bit as well as our counterparts. Perhaps you think of us as reckless, Twilight, and that would not be entirely unfair… but my sister and I have the power and focus to cast the spells flawlessly.”

“Well… okay then!” said Twilight. “So I can only breed one of you at a time, so who’s first?”

Nightmare Moon answered that question by swatting Daybreaker's hand away from Twilight’s cock and straddling Twilight’s thighs. Kneeling on the bed, the dark mare towered over Twilight Sparkle; her huge jet-black tits were right in the shorter mare’s face, and her lusty smile loomed above.

“I’ll have you first, love,” said Nightmare Moon. “My sister and I settled it in the dream realm. Best of one thousand and one games of rock-paper-scissors.”

Twilight raised a quizzical eyebrow.

Daybreaker sighed. “This sort of thing happens between highly competitive siblings,” she said. “Speaking of which, I am still suspicious that Nightmare Moon used her mastery of the dream realm to affect the outcome… but in the interest of our mutual goals, I shan't press the issue.”

“You see how far we have come, Twilight,” said Nightmare Moon, embracing Twilight and pulling her head into the darkness between her ebony tits. “Daybreaker and I get along wonderfully now, and we will bring this generous spirit to the task of motherhood. Once we bear you countless legions of foals, the three of us shall raise them in perfect harmony with one another.”

Twilight sighed when she heard Nightmare Moon boast about the “countless legions” of foals she planned to bear alongside her sister. She considered speaking up, but that would mean removing her face from Nightmare Moon’s cleavage. It was nice and warm in there, and Twilight’s cock was achingly hard; she didn’t want to keep herself waiting any longer than she needed to. And besides, that was probably just a bit of idle dirty talk; Daybreaker and Nightmare Moon knew they’d agreed to a sensible number of foals, and the two of them had been pretty agreeable lately.

“No more talk,” said Nightmare Moon. She stood, making the bedsprings creak with the weight of her towering, muscular form. “I’m taking that big purple cock, my love. Every wonderful inch of hot, hard stallionhood…”

She bent her knees, lowering her dripping pussy until it was touching the head of Twilight’s cock. “Ooh, Twilight,” she sighed, “every moment I go without this cock feels like an endless night…” She lowered her hips, taking the first few inches of Twilight’s cock and flexing her pussy to hold its girth tightly. “Tell me, Twilight, do you miss me when I am away? My immense strength, my glorious darkness… my tight cunt?”

Twilight fell back onto the bed, her cock still pointed straight up as Nightmare Moon impaled herself upon it. Pussy juice dripping down her shaft, she groaned in pleasure and clutched at her tits. “I do… I do miss you when you’re gone,” she moaned. “I love Princess Luna… but…”

“But what?” prompted Nightmare Moon. “You prefer me to Luna, my love?” She lowered herself past Twilight’s medial ring, clenching again to squeeze the fat purple shaft.

Twilight hesitated, whimpering as her cock trembled inside Nightmare Moon’s marehood. “Don’t… make me badmouth my wife…”

“Oh, relax,” said Nightmare Moon. She let her ass drop until Twilight was balls-deep inside her. “I am Princess Luna, my love. If you heap praise on my body - my physique, my pussy, my godlike power… you’re praising Luna as well.” She lifted her hips and let herself drop again, making Twilight moan. “And your praise may inspire me to ride your cock much harder…”

Twilight pawed at herself, groping her tits as she writhed on the bedsheets. “I love Luna,” she repeated, “But seeing her power unleashed is so hot… when I’m inside you, I’m fucking the Mare in the Moon, the ancient terror of Equestria, who brought on endless night… I can feel the same passion that made you a monster, but it’s all for me…” Nightmare Moon’s ass came down again, and Twilight shuddered as her cock was enveloped once more. “Ah, I’m sorry… I shouldn’t have called you a monster, it’s just-”

“No, my love,” said Nightmare Moon, grinning down at Twilight as she once again lifted her body. “No, I’ve been called far worse, but from you? Even that nasty word is as sweet as honey. Call me whatever you wish, so long as you praise my power and fuck my deep, dark cunt.”

“I was… scared of you, when I was younger,” gasped Twilight, thrusting her hips to meet Nightmare Moon’s descending pussy. “Too scared to go out on Nightmare Night. When I saw a dark shadow, I thought that you were coming into my bedroom…”

“And now we are sharing a bedroom,” said Nightmare Moon. “And rather than frightening children, I will be bearing them. Raising them. When I make you cum, Twilight Sparkle, when your lovely cock erupts in a fountain of warm white seed… my fertile body will swell with our foals. My belly will swell with life, growing to such an immense size, filling with scores of foals, legions of foals, countless little ones… I will bear them all for you, my love, I will take on this burden to show you the depth of my love for you…”

Twilight drew a shaky breath, clutching at the bedsheets as she felt climax approaching. “Nightmare Moon,” she groaned, “We’re just having six, remember? Three for you, and-”

“I recall the conversation, Twilight,” said Nightmare Moon, cutting Twilight off with another downward slam of her hips. “Indulge me, love, in my idle dirty talk… I am aware of the arrangement you made with Luna, but I cannot get the image out of my head. I imagine myself gravid, heavy with a litter of your beautiful foals, countless in number… surely it arouses you as well, Twilight. When you think of me that way, my love, does it make your big, hard cock throb with need? Does it bring you closer to the explosive climax that will fill me with your potent seed?”

“Y-yes,” Twilight admitted. “It’s an irresponsible fantasy, but… being potent, making you and Daybreaker into broodmares, swelling you with my foals, it makes me… nnnghh…”

“Yes, yes!” said Nightmare Moon, slamming her hips down faster and harder. “Picture me as your beautiful black broodmare, proudly carrying your foals, made immensely feminine by your divine seed… oh, my love, only you can give me what I need… cum for me Twilight, erupt within me and fill me with your love…”

Twilight thrust her hips upward one last time, and she felt a lurch within her as her nuts tightened against her body. Her limbs went stiff, her teeth clenched, and a mind-shattering eruption of pleasure made her cry out in bliss. Nightmare Moon’s pussy clenched down hard on her throbbing shaft, tightening around it as cum pumped up its length.

“Yes!” cried Nightmare Moon. “Your warmth, your love, your potency! Cum for me, Twilight Sparkle, erupt within me, give me buckets of your miraculous seed so that I may grow large and bear you a litter to rival the…” Nightmare Moon paused, her heaving chest growing still as her breaths halted. She’d nearly forgot about the spell! The spell she’d conspired to alter, the spell that would truly give her a litter worthy of a Princess. She gathered power in her horn, recalling the complex spellcraft that she’d studied and adapted…

And then she felt her pussy clenching, throbbing with a force beyond her control. No, she only needed a moment more! She couldn’t let her climax stop her from casting the spell - even if it was nearly impossible to focus, even if waves of pleasure were drawing her deeper into mindless bliss… she was Nightmare Moon, a mare of mighty will and unbreakable conviction, and she would have what she desired!

The spell left the tip of her horn, flowing through her body and into her ovaries. Satisfied, Nightmare Moon allowed herself to give in to pleasure; she threw her head back and cried out wordlessly as pleasure pounded at her senses. When it came to an end, she drew a long, slow breath - and then collapsed onto Twilight, like a toppling ebony statue of feminine perfection.

And it took Daybreaker no time at all to move in and shove her sister aside, eager to take her turn on Twilight Sparkle’s cock. One hand had been in her pussy for some time, massaging her marehood as she watched Nightmare Moon ride Twilight - and she left that hand there, using her other hand to cup Nightmare Moon’s bottom and lift her off the long purple shaft. Lifting an Amazonian mare one-handed was quite a feat, but Daybreaker was the power of Princess Celestia unchained - so it was hardly any trouble for her to lift her sister and drop her onto an empty portion of the bed.

Daybreaker grabbed Twilight’s cock by the base, letting Nightmare Moon’s feminine nectar drip down her fingers. “Now you are mine once more, Twilight,” she said, squeezing Twilight’s shaft to confirm its stiffness. “And I intend to make good use of our time together. I trust you still have lots of cum for me? I will not settle for less than you gave my sister, Twilight, for I intend to bear you a litter just as large… if not larger.”

“I have… plenty of cum,” said Twilight, propping herself up on her shoulders and meeting Daybreaker’s eyes. “As for the ‘litter,’ though… don’t forget, we’re only-”

“Yes, yes,” said Daybreaker, with a roll of her eyes. “Celestia agreed to three. I would not forget, Twilight Sparkle, and I would do nothing that jeopardizes or happiness together. I am delirious with love for you, forever your devoted servant…” She lay back and parted her thighs, giving Twilight a good look at the glistening folds of her marehood. “If you’ll only make me your broodmare, Twilight, I will show you the depth, the power, the fiery heat of my love for you…”

Twilight pulled herself to her knees, getting ready to climb atop Daybreaker’s reclining body. “All right,” she said, “Trust me, I’m more than happy to make you my broodmare, just as long as you remember-”

“Oh, Twilight, do not become a bore!” said Daybreaker, running her finger up and down her pussy lips. “I love your precise, careful mind, Twilight, but you must not allow it to stand in the way of your pleasure. Or mine.”

Twilight bared her teeth in a cruel, snarling smile. “I am not boring,” she said, crawling across the bed until the head of her stiff cock dangled just above Daybreaker’s pussy. “I am a thoughtful and intelligent mare, and I use those qualities to bring my best to every task I undertake. Including the task of knocking up my gorgeous wife.”

Daybreaker laughed. “A fine idea, in theory,” she said, “But you cannot think your way into being a passionate lover. The same qualities that made you a faithful student and a diligent Princess may serve you poorly in the bedroom.” She reached down and grabbed the head of Twilight’s cock, lowering it so that it touched the lips of her pussy. “You must abandon thought, Twilight, abandon all worry and doubt. Become a beast for me, my love - a horny, rutting beast who desires only to empty her fat nuts and fill her broodmare with a lovely litter of foals…

”Well, I would just hate to bore you,” growled Twilight. She gripped Daybreaker’s shoulders, steadying herself on the bed. “So if it’s a beast you want, then I’ll just have to rise to the occasion.”

Twilight slid the first two inches of her cock into Daybreaker - and then she rammed the rest in, pounding Daybreaker’s pussy with such force that it even shocked the fiery mare. Daybreaker cried out in surprise - but surprise soon turned to approval, and she screamed for more. More, and harder, and deeper.

And Twilight was only too happy to provide it. The accusation of being boring had stung deeper than she'd like to admit - and fortunately, she had a straightforward way to prove Daybreaker wrong. Grunting through gritted teeth, Twilight lifted her hips and thrust again, giving Daybreaker's cunt a punishing pounding.

“Am I a beast now, Daybreaker?” growled Twilight, her face an inch from the other mare’s. “Am I the big-dicked, brutally potent mare that the great Daybreaker demands?”

Passion burning in her chest, Twilight kissed Daybreaker. Her probing tongue conquered Daybreaker's mouth, as her hips thrust again and again in the Amazonian mare’s tight pink cunt. Twilight was sweating, moaning, her nuts slapping against Daybreaker's thighs - she was giving in to the horny beast, and it felt good.

Twilight pulled back from the kiss, lifting her body so that she looked over Daybreaker. “Still think I'm boring?” she tanmted. “My broodmares don't speak to me in that way Daybreaker. You and your sister… you serve me. Your bodies exist for my pleasure, your wombs are vessels for my progeny…”

She reached down and grabbed Daybreaker’s tits, sinking her fingers into the soft gloves and massaging the fat pink nipples with her palms. “You will accept the divine gift of my seed, you will carry my foals, nurse them and raise them…” She clenched her fingers, squeezing Daybreaker's tits good and hard, jackhammering her hips into Daybreaker's cunt. “...and you will never… fucking… call me boring! Now tell me, Daybreaker… whose broodmare are you?”

“Twilight Sparkle,” gasped Daybreaker, her mane growing redder and hotter as her climax came nearer. “I'm Twilight Sparkle’s broodmare…”

Twilight rammed herself into Daybreaker. “Do you love her?”

“...yes, of course…”

“Do you serve her?” Another thrust. The bedsprings groaned in protest.

“With every heartbeat… every breath…”

“That’s right,” said Twilight. “The Princess of Friendship commands the greatest power in the universe. I am greater than the blazing sun,” she grunted, thrusting herself deep into Daybreaker. “I command magic itself.” Another thrust, deep and hard, making the bedsprings creak in agony. “How fitting, that I should conquer the royal sisters… subdue their wild and powerful dark sides… and put their bodies into service, bearing my… nngh… proud lineage.” Two more thrusts, and Twilight felt herself nearing the point of no return, her stallionhood throbbing and her nuts tightening. “Swear yourself to me, and I will give you the gift of my divine load…”

“Yes, yes!” cried Daybreaker. “I serve you, my love, I am conquered… enslaved by your love! Bind me to you, fill me with foals… I swear myself eternally… ahhh-”

Like her sister, Daybreaker had nearly forgotten her intention to cast the spell that would boost her fertility. In the last second before climax, she summoned the magical diagrams into her mind, made her alterations in lines of crimson flame, and sent the spell up into her horn. It flowed through her body, accomplishing its purpose… but as soon as the first wave of climax hit Daybreaker, she forgot all about it once more. While pleasure overwhelmed her mind, Daybreaker stared up in awe at Twilight Sparkle, still grunting and thrusting like a horny beast. The Princess of Friendship had never looked so powerful, so commanding; in this moment, she was truly the equal - no, the superior - of the royal sisters and their unchained power.

Twilight thrust again, hilting herself in Daybreaker’s pussy, and with a deep groan she climaxed. Daybreaker felt the flow of seed, pumping through the shaft, and she sighed with bliss as the warmth flowed into her. She felt as though she could feel the swimming of Twilight’s sperm, the movement of her eggs through the inner workings of her womanhood. It was purely imaginary, nothing but fantasy born of sexual frenzy… but the idea took Daybreaker’s mind to a place of perfect bliss.

But Twilight was still cumming. She kissed Daybreaker, probing deep into the mare’s mouth as her cock offered up gush after gush of warm white cum. When the last spurt had lurched from the head of her cock, her mind went utterly blank… and she rolled off of Daybreaker, pulling her slick, softening cock from the mare’s tight pink cunt.

And as she rolled off one sister, the other one was there to embrace her. Nightmare Moon caught her in arms of perfect ebony muscle, and Twilight rested her head on the mare’s big black tits. Daybreaker - already half asleep - rolled over and put her arm around Twilight, mumbling happily when her fingers found Twilight’s soft mane. They stayed that way through the night; sandwiched between two Amazonian mares, Twilight let herself drift into slumber.

But even in this perfect moment - held by two statuesque goddesses, listening to their powerful heartbeats - a thought nagged at her. Daybreaker and Nightmare Moon had been quite vocal about their desire for huge, irresponsible numbers of foals. Twilight had grown to love the royal sisters’ dark sides, but they did not share the wisdom or restraint of their other halves. Could they truly intend to…?

Twilight snorted, dismissing her worries. It was dirty talk, just like they had said. Nothing more. Surely.

Chapter 4

Luna kept one hand under Daybreaker’s chin and one on her shoulder. There wasn’t much point in holding her sister’s hair back; where most ponies had a colorful mane, Daybreaker had a line of perpetual flame. No need to worry about it flopping into the toilet bowl.

As the blazing alicorn knelt retching in front of the toilet, her fiery mane had shrunk to a low, guttering flame - a reflection of the full-body misery she was experiencing. Groaning, she lifted her head and brushed off Luna’s hands. “Nngh,” she mumbled, “whatever happened to ‘our bodies do as we will?’”

Luna patted her bare belly, recalling her own ongoing struggles with morning sickness. A three-month belly wouldn’t normally be as prominent as the ones she and her sister were sporting, but the sheer number of growing goals made the two of them look quite a bit farther along. “Perhaps, Daybreaker, you were… somewhat blinded by ambition?”

Daybreaker made a nauseated sound, purely out of disgust for Luna’s words. “That expression is the product of small minds, sister. Do not let this trial sap you of pride and passion!” She grasped the toilet bowl and attempted to stand, but a fresh wave of physical unease made her think better of it.

“Our ambition is not to blame,” Daybreaker said. “If that fool Celestia had not vetoed it, I would have strengthened our celestial link and drawn a limitless bounty of sustenance from the sun. Were this body stronger, nourishing Twilight’s foals would not be so taxing.”

Luna smirked. “Celestia, that fool. I can’t imagine why she’d object to radically changing how her body works in the midst of a pregnancy.”

“Sister,” groaned Daybreaker, “your sarcasm, as ever, is…”

Daybreaker froze fearfully - then she lurched forward, retching over the toilet bowl once again.

The sound of creaking bedsprings made Celestia pause as she passed the door to Luna’s bedchamber. Odd, she thought - Luna’s bed was exceedingly luxurious. It would take a hell of a lot of weight to make the springs creak like that. Just what was going on in there?

The lock on the door was magically and mechanically complex, but Celestia had ample experience unlocking it. With a quick flash from her horn, she opened the door and leaned her head into the noisy bedroom.

The scene within did not disappoint. It was not Luna on the bed, but Nightmare Moon - a larger, beefier version of Celestia’s sister. That certainly explained the overburdened bedsprings. And the cause of the rhythmic creaking was also readily apparent: Nightmare Moon had the fingers of both hands deep in her pussy, thrusting forcefully in her marehood. She was throwing her whole body into the act of masturbation, in fact; with each motion of her hands, she threw back her shoulders, thrust her hips, and kicked her legs. Her body language and flushed face spoke of frustration, and the sweat on her brow told Celestia that Nightmare Moon had been at this for quite some time.

Nightmare Moon saw Celestia enter the bedroom, but she barely acknowledged it; even in their normal forms the royal sisters were quite comfortable with each other, and Nightmare Moon was even less concerned with modesty and personal boundaries.

“Greetings, conqueror,” said Celestia, smirking at Nightmare Moon and giving her a casual wave. “Don’t tell me it’s your own marehood that has you so thoroughly vexed.”

“I have been at this for the better part of an hour,” grumbled Nightmare Moon, “and I am growing no closer to release. Even the basest of beasts… surely… is not shouldered with such intense heat.”

“I have heard of this,” said Celestia, taking a seat on the edge of the bed. “For some, pregnancy results in a flood of hormones. More intense than puberty, they say. And with your powerful body and tremendous pregnancy, it seems it may be hitting you harder than most…”

“I have no appetite for your pity, Celestia,” said Nightmare Moon. “Will you not help me?”

“Help you?” asked Celestia. “Twilight Sparkle may have awoken numerous kinks in me, sister, but incest is not among them.”

Nightmare Moon groaned, shifting one sipping hand to her bosom in the hopes of stimulating her fat, dark nipples. “Do not jest with me, sister,” she grunted. “Simply fetch me Twilight. She is the only one who can sate this beastly need.”

“Twilight is too busy to attend to you, I’m afraid,” said Celestia, leaning back on the bed to give Nightmare Moon’s flank a gentle pat. “As you know quite well, our pregnancies render us unfit for duties that call for great exertion or significant risk. Twilight is the only one qualified to take over in our stead, naturally. And a mare spread so thin - even one as brilliantly capable as Twilight Sparkle - cannot spare the time to help you with something you should be able to do yourself.”

Celestia paused thoughtfully, unable to resist the urge to toy with her sister’s Amazonian alter ego. ”Of course, the situation would not be nearly so dire if someone had not had the ingenious idea to multiply her pregnancy…”

Nightmare Moon snarled, her frustration only growing. “Then fetch me a courtesan!” she bellowed.

Celestia shook her head. “It has been three centuries since we have budgeted for royal courtesans, sister dear. We could look into hiring the services of a qualified individual, but I doubt we could get them here in a timely fashion…” She twirled a loop of her swirling hair around her finger. “Oh, but I do have something that would help. Wait here, I’ll be back shortly.”

Nightmare Moon gave a grunt of acknowledgement as Celestia left the room. With her sister no longer providing a distraction, she rededicated both hands to the stimulation of her marehood - and magical darkness engulfed her horn as she created a set of magical fingers to aid her hands. Moaning, sweating, tormenting the bedsprings with her massive bouncing body, Nightmare Moon began to sense the smallest bit of progress. She was inching towards the release that would free her from this intolerable heat…

Celestia burst back into the room and tossed a long rectangular box in Nightmare Moon’s direction. Once the package had bounced off her ass and settled on the bedsheets, Nightmare Moon picked it up and removed the top, peering skeptically at its contents. “What is this?” she demanded.

Celestia was a bit taken aback, having not anticipated any confusion on Nightmare Moon’s part - but she opted to give a straightforward answer. “It’s a dildo, sister. You use it for-“

“I know what a dildo is, Celestia!” barked Nightmare Moon. “I am Nightmare Moon, sister! Empress of the Stars, Mistress of the Dark! This lump of rubber is beneath my dignity.” She pointed the thick black dildo accusingly at Celestia, but its wobbling robbed her gesture of its intended gravity.

Celestia shrugged and rose from the bed. “I’m afraid that is all I can offer you, sister - and if I were you, I would avail myself of the tools at hand. Now if you’ll excuse me, I’m off to check on Twilight, who’s holding the royal court. Ta.”

Nightmare Moon snarled at the closing door as Celestia departed. “Sometimes, dear sister, I dearly miss the days when you were afraid of me.”

And then, sighing, she slid the head of the dildo into her marehood. It was long, thick, and firm - and with a bit of imagination, it was a little like having Twilight Sparkle’s cock filling her cunt. Yes, she supposed this would do.

“Ohh… this is misery,” moaned Daybreaker, rolling onto her side so that her chest faced the rapidly rotating fan. A shiver went through her godlike physique as the air cooled the sweat coating her breasts and her abs - but once the shiver passed, Daybreaker was once again moaning at the oppressive heat. She peeled a damp towel from her forehead and tried to dry her chest with it, but it was too saturated with sweat to serve any purpose. It was soaked - just like Daybreaker herself, just like the rumpled sheets beneath her body.

“Twilight,” she groaned, rolling onto her back and propping herself on her elbows so that she could see past her five-month belly. “This is… amusingly enough… the first time I have ever felt like I was on fire.”

“That is funny,” agreed Twilight. She worked her thumbs into the sole of Daybreaker’s right foot, tenderly massaging the sore appendage. With her head, she gestured toward the tall pitcher of water on the bedside table. “Drink!” she said. “You’re sweating nonstop, and you need to replenish yourself… or maybe try and extinguish your mane, if you think that’ll help more.”

“No, my beloved,” said Daybreaker, lazily brushing a hand through her burning mane. “I am afraid this thing never goes out. Usually I am quite proud of it, Twilight, but right now… oh, it feels horrid.”

Lying motionless, Daybreaker levitated the entire pitcher to her mouth and poured an overflowing mouthful past her lips. After swallowing lustily and gasping for breath, she met Twilight’s eyes again.

“So this is what mortal ponies feel each summer,” said Daybreaker. “I am surprised there is not an annual rebellion.”

Twilight smiled, relieved that Daybreaker still had her sense of humor. Her fingers massaged the ball of Daybreaker’s foot, and the fiery alicorn moaned in pleasure.

“Indignity upon indignity,” sighed Nightmare Moon, holding her arms awkwardly over her head as she awaited Twilight. Her body was bare, because clothing was unbearable at the moment - but it was nearly as unbearable to look down at herself and see the hives covering every inch of her skin. She struggled to remain perfectly still, resisting the urge to scratch her immense eight-month belly.

Even Nightmare Moon had to admit that her gravid belly was unreasonably huge. The heavy, kicking litter of foals inside her - the litter she’d schemed to achieve - was a wide, weighty burden that dwarfed the pregnancy of any mare who had come before her. It was doubly absurd on Luna, who couldn’t even get her arms around it - but even her taller, beefier alter ego could barely manage to lug the massive baby bump around.

Nightmare Moon breathed a small sigh of relief when she saw Twilight enter the bathroom, holding a sealed clay pot in her hands. “This is as much anti-itch cream as Zecora could provide on short notice. I’ve asked her to make more in case the symptoms return…” she popped the lid off the jar and set it down on a countertop, using two fingers to scoop up a thick glob of the medicinal cream. “...but if I know Zecora, this should fix you right up.”

“I hope you are right, my love” said Nightmare Moon. “I like to think that my graceful and powerful body is pleasing to your eyes… but with my skin covered in head awful itching hives, even I can barely stand to look at myself.”

“You’re still beautiful, Nightmare Moon,” said Twilight, spreading the cream on a spot just above the alicorn’s belly button. “The same dark and alluring conqueror as always. And this belly of yours…” she ran her hand over the curve of Nightmare Moon’s tummy, spreading the soothing cream over its surface. “I think I’m going to miss this when it’s gone. The hives… not so much.”

Nightmare Moon could only sigh with relief as Twilight’s hands - and the medicinal cream they were spreading - worked their magic.

Three doctors and a half-dozen nurses kept their distance as Twilight Sparkle focused her magic, building a pair of glimmering lavender auras around the beds that Daybreaker and Nightmare Moon occupied. The hospital’s staff had prepared admirably for this day; they knew to expect the imposing alter egos of the royal sisters, who were larger and more willful than the princesses they were familiar with. What they hadn’t anticipated was just how violently they would thrash when contractions hit. The two other beds nearby, bent and broken, were a testament to that.

The Canterlot hospital didn’t have the sort of heavy-duty, reinforced beds it would take to withstand that sort of punishment. No such beds existed, as far as anyone in Equestria knew, because no pony had ever had need of one. There were alternatives, though - and Twilight, fortunately, knew a variety of useful spells that the medical staff didn’t.

The enchantment she was casting now was a reinforcement spell, a complex and powerful magic that increased the durability of its target without impeding its function. The magic was only as strong as the unicorn creating it - but in Twilight’s case, that wasn’t a problem. The beds were steady as a rock once the spell was cast, and Twilight gestured for the doctors to return to their work - but she stayed where she was, kneeling between the beds, using all her focus to maintain the enchantment. The strain was already getting to her, creating an ache at the base of her horn… but Twilight didn’t mind. Seeing what her wives were going through, she knew she had it easier than either of them. And the pain, in a way, made her feel closer to them.

With their beds reinforced, Daybreaker and Nightmare Moon were better able to steady themselves. Without fear of shattering the bedframe, they wrapped their fingers around the handles on either side and braced their feet in the stirrups, giving the doctors room to work.

Daybreaker grit her teeth, suddenly seeming not just pained but annoyed - and despite the relative silence in the room, she abruptly snapped at someone. “Your color commentary is neither desired nor needed, Celestia. Shut up."

Twilight bit her lower lip, failing to hide the grin that grew on her face. “Now, now, my wives,” she chuckled, “play nice, all right? For the foals’ sake.”

Daybreaker laughed ruefully and turned to Twilight with a smile that revealed her sharp white canines. “Be careful, my dear wife,” she muttered, “I cannot silence Celestia with a fist to her jaw, but you? You I can reach.”

A nurse approached Nightmare Moon, wearing the same calming smile she did for all the patients she tended to. She’d seen the alter egos of the princesses at many previous checkups, and she’d learned to think of her less as a mythical figure of ancient evil and more as an expectant mother. “How are you holding up, your majesty?” she asked.

Nightmare Moon lifted her chin haughtily, and an unseen breeze seemed to lift her dark mane. "I am Queen of the Umbra,” she intoned, ”the Terror in the Shadows. I have claimed victory in ten thousand battles. I have been burned by dragon fire, scoured by the acid barbs of the horrors of the deep, and been impaled on claws of pure void. To me, pain like this is a trifle."

The nurse nodded patiently. "So I take it you will pass up the numbing agent, then?"

Nightmare Moon winced and let out a short, nervous laugh. "Well… Let us not be too hasty. Even an umbral terror would be wise to avail herself of every advantage… including the miracles of modern medicine.”

With the beds reinforced and the numbing agent administered, the delivery became something almost normal. The staff was prepared for every complication known to medical science and magical study - and they’d accepted, somewhat grudgingly, Twilight Sparkle’s input on the unheard-of complications that could occur in this unprecedented situation.

But now, on the day of the delivery, there was no occurrence so momentous as what Twilight’s anxious mind had conjured up. It was no cakewalk either; no mare had ever delivered nine foals at once, and no hospital had ever cared for two such mares simultaneously.

Throughout the last nine months, Daybreaker and Nightmare Moon had been humbled by the trials of pregnancy; even with their immense power and godlike physiques, they were mares. They weren’t above the pain of labor, nor the fear of what could go wrong. They were helpless in this moment; the safe delivery of their foals was in the hands of the doctors and nurses that surrounded them. All they could do was endure, and push.

And in time, the first of the foals began to crown. The sisters were nearly in sync, either through magic or mere coincidence, and the first pair of babies were in the hands of nurses at practically the same moment. Two little alicorn girls, which was just what their mothers were expecting; it had been difficult to get a clear picture of such a crowded pair of bellies, but the doctors’ best guess had been that all eighteen of the babies were alicorn girls. And the babies proved them right, one by one, as Daybreaker and Nightmare Moon grit their teeth and pushed.

And they probably would have kept pushing long after all their foals were delivered, had Twilight placed a hand on each of their shoulders and told them it was over. But before the new mothers could even smile, their brows furrowed in concentration.

It was a moment before Twilight noticed, though; she was wiping sweat from her brow and massaging the base of her aching horn. “Eighteen alicorn babies,” she sighed. “Well, thanks to Flurry Heart and Sunburst, we know a thing or two about what to expect and how to deal with it. For now, we, uh…” she looked to her left and right, and saw the knitted brows on the sisters’ faces. “Are you two all right?” she asked.

The sisters turned to Twilight and spoke simultaneously.

“Luna and I-“ said Nightmare Moon.

“Celestia and I-“ said Daybreaker.

The sisters paused and looked at each other. Their weary eyes met, and Daybreaker nodded silently.

“I was having an internal debate with Luna,” said Nightmare Moon, “and Daybreaker with Celestia, it would seem… about which of us gets to hold the babies first.”

“Oh,” said Twilight. “Do you need my help deciding? I could just flip a coin, if that’d make things easier.”

Daybreaker raised a hand to silence Twilight. “Very kind of you, Twilight, but we and our other halves are big girls. We will work it out ourselves.”

There was a silent moment as the alicorns spoke with their other halves. They nodded and began to shrink, much like they did when they transformed back into Luna and Celestia: their height and muscle mass diminished gradually, and their manes faded into the familiar hues of the royal sisters of the sun and moon.

But the transformation halted midway, leaving them not quite in one state or the other. They stood taller than the princesses ordinarily did, with thicker thighs and more powerful arms. The princess of the day still had a mane of raging flames, but it burned in the colors of Celestia’s mane. The princess of the night was a darker shade of blue than Luna, but not the inky black of Nightmare Moon’s cost. And both mares had mismatched eyes - one round, one slitted.

The transformation ended just in time for the royal sisters to see the nurses return to the room, wheeling in carts that held their freshly washed newborns. They were healthy, and strong, and beautiful, the doctors told them, as if the three royal parents couldn’t see that for themselves. The royal sisters, their bodies still hybrids between their multiple selves, stretched their arms out to receive their foals as the nurses placed them in their arms one by one. And Twilight Sparkle held her breath, tears welling in her eyes as she watched her wives smiling down at each tiny bundle. There were so many new little ponies in her family, but she was already in love with every one of them.

Chapter 5

“Do you recall the very first feeding?” asked Nightmare Moon, shifting her torso to get Gentle Nova and Midnight Satin into a more comfortable position. “Such a serene moment of connection, a physical and spiritual bond between mother and foal. If someone had told me - back then - that the process would become a chore in less than a single month, I would have…” she sighed, as the infants at her breast suckled quietly. “I cannot say. Cursed them with nightmares, perhaps.”

“I’m sure,” said Celestia, herself nursing Amaranth and Summerfree. “And I imagine the novelty would last longer for new mothers with only one foal to nurse. You have done nine times the work, sister; no one would blame you for growing frustrated with the task.”

“Thank you,” said Nightmare Moon. “My patience has been saintly and-” there was an impatient wail from Curio’s crib, and Nightmare Moon raised her voice to speak over it. “...and it feels good to have it acknowledged.”

Celestia smiled. “All the more impressive, Nightmare Moon, seeing as you are an incarnation of purest evil. You don’t suppose that affects the quality of your milk, does it?” Nightmare Moon scoffed, and Celestia pretended to ignore it. “Myself, I’ve been careful to make sure my foals get a proper balance between myself and my alter ego. Too much of Daybreaker’s milk, and they are certain to grow into tyrants.”

Nightmare Moon cracked a smile. “I am nearly positive that is not how it works,” she said. “The foals, for their part, do not seem to have a preference between my milk and Luna’s. The only distinction they make is between being hungry and being fed.” As if to affirm her point, there was another chorus of wails from the nearby foals who were still waiting to nurse. “Sister, did you realize that foals needed to be fed every few hours? And did it occur to you that each of them would grow hungry at about the same time? Because I confess that I was not in command of those facts before we chose to become mothers…”

“Oh yes?” chuckled Celestia. “I suspect that even Daybreaker - ambition incarnate - would have reconsidered bearing nine foals all at once if the practical realities had been laid bare for her. Even with adequate reserves of milk, only being able to feed two at once makes for a grueling routine.”

“I mentioned this to Twilight yesterday,” said Nightmare Moon, “and she offhandedly replied that she had been unable to devise a practical way to give us additional breasts. I had intended to ask her a follow-up question - several, actually - but business called her away before I was able to.”

Celestia laughed softly, shaking her head. “Ah, that’s my Twilight Sparkle,” she said. “Fearlessly seeking solutions that meeker ponies would not even dream of.”

“Yes, indeed,” muttered Nightmare Moon, somewhat distractedly. Another wail filled the nursery, and her ears flicked irritably. “...tell me, sister, how is it that you keep that infuriatingly serene smile on your face at all times? I know you wear that smile when you hold court; did it simply freeze that way?”

Celestia noticed that Amaranth had stopped suckling. She lifted the foal to her shoulder and gave her a gentle pat on the back, encouraging the baby to burp. “Court has something to do with it,” she said. “Our childrens’ cries, no matter how loud, are in many ways preferable to the empty, honeyed praise of ponies who come before me begging favors.”

Nightmare Moon snorted. “If you are weary of dealing with liars, why not cut their tongues out? You know… to send a message.”

Celestia chuckled. “I’ve thought about it,” she said, “But what would I do with so many tongues? Sooner or later they’d start to smell.”

“Even when I am awake,” said Daybreaker, “my sister has a way of inflicting nightmares on me.”

Moonlight Lance gurgled in response, reaching one tiny hand in Daybreaker’s direction. She was sharing a wide play-mat with the rest of Nightmare Moon’s foals, all of whom - for the moment - were Daybreaker’s responsibility.

“Is that funny to you?” asked Daybreaker, kneeling down to confront Moonlight Lance - although she kept her tone gentle and held a smile on her face. “Calling you foals little nightmares was not intended as a compliment. Sooner or later, though, I suppose I will have to start watching what I say around you, won’t I? Once you’re old enough to understand what I’m saying, I’ll have to be much more careful… especially if one of your mothers is listening.”

“Well, for now,” said Daybreaker, extending her finger for the goal to grab hold of, “I will tell you that your mother, Princess Luna, was terribly irresponsible with you and your sisters. While my foals are comfortably in the hands of trusted caretakers, Luna carelessly gave her childcare staff time off all at once. Now she and Twilight are off on matters of state, and I am the only one qualified to look after you. Did your mother do this with malice?” Daybreaker leaned in and kissed Moonlight Lance on the forehead, just below the foal’s little horn. “Probably not! But someone will listen to my tale of woe. Even if it is just you, your sisters, and your little ears that understand none of it.”

“Well,” sighed Daybreaker, “This is enough complaining from me. I don’t wish to instill any bad habits into you girls. If you want to collect grievances and nurse grudges like Mommy Daybreaker, that will be your decision - not something I forced upon you.”

“Yes, nothing but by-the-book parenting from me, young ones,” said Daybreaker. She picked up Moonlight Lance with both hands and lifted the foal to her shoulder. “And if the nine of you end up believing that I am cooler than Luna, then-“

There was a high-pitched hiccuping sound, and Daybreaker curled her nose instinctively as she watched a spot of spit-up drip down her blouse.

She sighed. “Well, I appreciate your candor,” she said. “I have years to improve your opinion of me.” She cradled Moonlight Lance in one arm, grabbed a small cloth from a bag she kept handy, and wiped off the stain as best she could. “Is that out of your system, Moonlight Lance?” she said, dabbing the foal’s mouth with a clean section of the cloth. “No more coming up? No distress?”

She stared into Moonlight Lance’s eyes, and the foal stared blankly back for a moment - then broke into a carefree smile.

“Well all right then.” said Daybreaker. “Back you go, Moonlight Lance. There are eight other foals who crave my attention just as much.” She set Moonlight Lance down on the playmat and briefly shook a colorful toy in front of her face, giving the baby something to fixate on in her mom’s absence.

“Now then, who among you most needs to be parented?” asked Daybreaker. “I have to parent you in the order of most to least need, little ones, or this whole nursery will descend into anarchy.”

Daybreaker thought she spotted distress on the face of one foal in particular. “You there,” she said, pointing a finger at Aurora Runner. “What is it you need? Daybreaker is at your service - a privilege few have ever received.”

She knelt by Aurora Runner, whose face wore a deepening frown. “Let us see what the trouble is. The most obvious culprit would be…” she manifested a small sphere of magical energy and prodded the front of the foal’s diaper. “Ah, there it is. A change will make you feel better.”

The sphere of magic expanded, split, and became a pair of floating hands. “I hope you’re not offended that I am not using my real hands,” she said, as she magically lifted Aurora off the mat. “I don’t wish to withhold physical contact, little one, but I prefer to do this job at a bit of a distance. Magic is ideal for that, as you’ll learn in due time.”

Daybreaker hovered Aurora Runner over to the changing table and held her above it. Still using magic to handle the dirty job, Daybreaker peeled the wet diaper away from the foal’s body and disposed of it. With a thorough application of sanitary wipes, she cleaned off Aurora’s lower half.

“There we are,” said Daybreaker, levitating the foal towards her body and cradling her in one arm. “Now that you’re properly sanitary, Aurora Runner, I can hold you close. Magic is a powerful and versatile tool, but there is no substitute for true closeness and warmth-“

Daybreaker paused, because she was feeling warmth in a way she hadn’t expected. A spreading, liquid warmth was permeating her blouse, and when she looked down her suspicions were confirmed: after leaving her diaper soggy, Aurora had delivered an encore performance directly onto Daybreaker.

“Oh, honestly,” groaned Daybreaker, scowling as she held the laughing foal at arm’s length. “Enjoy this sort of mischief now, small one, because as soon as you learn to speak I will expect you to explain yourself.”

She set Aurora down among her sisters. “I shall need to step into the bathroom and fetch a towel,” she said. “Before I let you out of my sight for several consecutive seconds, does anyone else have need of me?”

Tranquil Eve seemed to have something to say, if her crinkled nose and squinting eyes were any indication, so Daybreaker levitated the foal off the mat and up to eye level. “Little Eve,” she said, “your expression is ever so slightly troubled, yet your diaper is dry and you have been fed quite recently. Let me see if I can-“

Tranquil Eve sneezed, flinging an astonishing quantity of snot onto a previously clean patch of Daybreaker’s blouse. The blazing alicorn gritted her teeth, trying to keep a motherly smile on her face and holding back a frustrated bellow. If she let herself scream, she’d have nine crying foals on her hands in addition to everything else…

“I see,” sighed Daybreaker, setting Tranquil Eve back down. “Well, if that is all, I will clean myself off and return presently.” She looked down at herself, wincing at the mess she’d become. “It shouldn’t be long before your mother returns, darlings, and she will be heartbroken when she learns what precious moments she missed.”

“You like carrots,” said Nightmare Moon. “You have liked carrots since the first time you tried them, if memory serves.”

Nightmare Moon prodded Luminous Aether’s tightly closed lips with the little baby carrot. “We still source our carrots from the same farm, Luminous Aether,” she said calmly. “The carrots have not changed. Have you? Are you not the same foal who happily enjoyed all these foods only days ago?”

“No!” whined Luminous Aether, turning her head sharply and squirming in her high chair. Twilight Sparkle, who was having more luck getting the other foals to eat, chuckled softly at this.

Nightmare Moon narrowed her eyes to tiny, suspicious slits. “Is that so?” she asked. “If you are not my daughter, Luminous Aether, what are you? An intruder? Perhaps a changeling?”

Luminous Aether didn’t have an especially good comeback for that. She swiveled her head in the other direction, pouting, and Twilight Sparkle once again failed to stifle a laugh. Unfortunately, the other eight foals took notice of that; over the past several months, they’d started learning what made their mothers laugh or smile, and getting that reaction had become something of a game to them. Most of the time, that was a good thing. It was fun and entertaining, and - as Twilight pointed out - it showed that the foals’ emotional and social development was coming along nicely.

But every once in a while, the foals would begin to play this “game” at an inopportune time. They’d been eating happily, but when they saw the way Luminous’ refusal made Twilight smile, they began to join in one by one. Curio and Serene Dusk - whom Twilight had been personally feeding - abruptly shut their mouths, mimicking Luminous Aether’s refusal. Twilight couldn’t help but find it funny - which gave the rest of the foals the idea to pout and swipe the food off their plates.

“Oh no. No, this is not acceptable!” growled Nightmare Moon. Her eyes shone with cold moonlight, and her mane seemed to grow bigger and darker with each billowing wave. “Foals,” she intoned, with a voice that suddenly echoed through the dining room. “I have entertained this foolishness for long enough. I command you to finish your meals, children - before I lose my patience entirely.”

For generations, Equestrian foals had grown up with the legend of The Mare In The Moon - the tyrant who had almost plunged the world into darkness, who had been prophesied to return and conquer Equestria. They learned as children to fear her, and even as adults most ponies - faced with the dark conqueror - would be stricken with paralyzing terror.

Luna’s foals had not grown up with the legend of Nightmare Moon - they had grown up with the mare herself. In their eyes, her power, her stature, and her booming voice didn’t belong to a tyrant, they belonged to their mommy. Nightmare Moon didn’t want her children to fear her, naturally… but in moments like this, she wished she could scare them just a little.

But she couldn’t. For her foals, Nightmare Moon’s anger was just part of the game - so they reacted with more laughter and pouting, smacking their plates and knocking bits of food to the floor. “Ooh,” said Twilight, her own laughter starting to fade as the situation escalated, “I don’t think they like being ordered around! Well, Spike used to get like this, and I was just a foal myself when I had to feed him! There wasn’t… nine of him… but if I go one by one, then…”

Twilight turned to Curio, picking up a carrot and trying to get the foal to focus on it. But there were too many other things for her to look at - the other pouting foals reminded her of the game she was playing, and the reddening face of Nightmare Moon reminded her of why she was playing it. “This is harder than I remember,” Twilight admitted, looking helplessly up a Nightmare Moon.

“Foals!” bellowed Nightmare Moon, her anger ominously dimming the room’s lights. “No one is leaving until all of you have eaten! If you persist in this, I will keep you here for as long as it takes! I am eternal, little ones, and if I have to wait here for a month then…” her shoulders slumped. “...then I shall grow very tired… so please, just… eat…”

Nightmare Moon hadn’t realized just how little fight she had in her. Twilight Sparkle stood from the table to place a hand on her shoulder - and the foals, heedless, just slapped cheerfully at their plates.

Over the course of the last five years, “Mom duty” had become a formally scheduled task - which didn’t strike Princess Celestia as the warmest approach to the responsibility of parenting, but it was necessary when there were eighteen children to look after and a nation to run.

At any rate, Celestia wasn’t on Mom Duty at the moment. Daybreaker was, and she - more than her counterpart - could see the virtues of the system. She’d been looking forward to today’s shift, in fact; a new season of school had just begun, and this would be Daybreaker’s first chance to greet the children as they returned from the day’s schooling.

The decision to go with outside schooling as opposed to tutors had been a subject of some contention - Daybreaker had spoken out against it - but Twilight, as she often did, had put together a compelling case that put her doubts to rest. It was hard to say no to Twilight Sparkle, especially when she did her research.

So Daybreaker was on board with school, but letting her children out of her sight was still difficult for her. She wouldn’t be satisfied until she knew everything - and, ideally, until she could control everything. When the row of carriages arrived at the front gates and released the foals, the majority poured out with all the youthful energy Daybreaker expected of them… but there was one - Golden Shield - who dropped miserably out of the carriage and dragged her heels across the cobblestones. Daybreaker gave the others a quick greeting as she passed by them, then she stood in Golden Shield’s way, ready to intercept her dejected offspring. Golden Shield’s eyes were downturned, and she probably would have walked right into her mom’s legs if Daybreaker hadn’t pointedly cleared her throat.

“Golden Shield,” asked Daybreaker, once the filly at her feet looked up at her, “what troubles you?”

Golden Shield couldn’t quite make eye contact with Daybreaker. Hiding her face behind blue-and-gold locks, she sniffled and mumbled, “Nothing…”

Daybreaker knelt and put two fingers under Golden Shield’s chin, lifting it up so that the filly couldn’t help but look her in the eyes. “I won’t be lied to,” said Daybreaker plainly. “You can, and furthermore must, tell me the truth.”

Daybreaker waited as Golden Shield collected herself. After a series of loud sniffles, she presented the story in a somewhat disordered fashion. “There’s… at school… a colt… and he’s-” she sniffled again. “He was chasing me, and, and laughing, and, and when he caught me he had dirt in his hand, and…”

Daybreaker waited; as a mother she’d learned the value of listening, and the years had made her pretty decent at it. She wanted to let Golden Shield tell the story at her own pace - but when the filly broke into outright blubbering, she began to wonder if silence had been a mistake. She swept her daughter into an embrace, lifting her off the ground. Golden Shield wasn’t surprised when her feet left the ground; she knew that Daybreaker’s hugs were more powerful, more enveloping than Celestia’s. Her crying started to slow, but when she spoke again her words were still broken by sobs.

“I’m s-sorry,” Golden Shield choked out. “You got this dress for me, and you told me I looked pretty, and I wanted everybody to see because… and, I’m, sorryyyy…”

Interrogating Golden Shield seemed like a needlessly indelicate approach, so Daybreaker did what she could to piece the story together. Now that she was hugging Golden Shield, she could see the back of her dress and the line of red-brown dirt that trailed down its fabric. “Golden Shield,” she said, “Did that colt pour dirt down the back of your dress?”

“Yes,” sobbed Golden Shield. “I’m sorry-”

“There is no need to apologize, Golden Shield,” said Daybreaker, setting her daughter down on the cobblestones. “I knew this day would come. You have done nothing wrong, but this presents us with an opportunity for a very important lesson. Young one, the time has come for your first lesson in the fine art of revenge. Now, let us see… this colt started things with dirt, so for a forceful but proportionate retaliation, we might consider-”

The sound of a throat being loudly cleared made Daybreaker stop and look over her shoulder. Twilight Sparkle was standing by the front gates, surrounded by a ring of foals, looking at Daybreaker with one eyebrow raised.

“Oh, Twilight is here as well!” said Daybrekaer, with as much cheer as she could force into her voice. “I had thought I was the only one on Mom Duty, but here she is! Well, the three of us can have a chat about…” she grit her teeth, “conflict resolution. Won’t that be nice.”

“Okay, this is going to be hard for you to believe,” said Spike, once he’d sent the little dragon pups scampering across the courtyard, “since I was a perfect ray of sunshine since the day I hatched. But it turns out - sometimes - raising dragons can be pretty challenging.”

“Oh, you were an angel, that’s for sure,” said Twilight Sparkle. “I don’t see what you have to complain about, though. You’re raising your kids in the Dragonlands, where nothing flammable even tries to grow. Poor Mom and Dad could barely keep up with you once you started burping up fire; even after they taught me and Shiny how to do the fireproofing enchantment and we had practically the whole house dragon-proofed, you always seemed to find something you could ignite.”

“It’s a natural dragon instinct!” said Spike. “But… yeah, dragons start to be a real handful when they first get their fires. My scales are pretty sturdy, but dragons can still hurt each other if they’re not careful. Or if they just don’t know how to be careful. It’s a good thing the castle has this courtyard-” he stamped his foot on the stone floor, emphasizing its solidity, “-or it wouldn’t be safe for me and the kids to visit at all.”

At the other end of the courtyard, the six little dragons collided with the alicorn children. Smaller in size, and badly outnumbered, the dragons were quickly swept up into excited embraces. Spike titled his head thoughtfully as he watched the scene unfold. “So, you did fireproof your kids, right? I mean, you’re not the type to overlook a detail like that, but I should probably ask.”

“They’re all taken care of,” said Twilight. “I had them fireproof themselves, actually! They were so excited about getting to meet their dragon cousins, it seemed like a good opportunity to teach them something new.” She laughed. “I actually told them they wouldn’t get to meet their cousins if they didn’t learn the spell. I think they believed me!”

Spike gave Twilight a disapproving look and a wry smirk. “You lied to your children?” he said. “And here I was worried I would end up being the worst parent out of the three of us.” He shrugged. “Well, there’s eighteen of them, I’m sure some of them will turn out okay in spite of your shoddy parenting.”

“They’re all going to turn out amazing, thank you very much,” said Twilight. “Look how good they are at making friends!”

The pony children were getting along well with the dragons, although they were treating them a bit more like pets - or toys - than fellow children. At the moment, they were passing the little dragons back and forth, trying to figure out a consistent way to make them burp up flame. Every once in a while they managed to coax a jet of colorful flame from one of them, and they attempted to and they seemed to be casting meaningful glances at the hanging banners on the perimeter of the courtyard. It hadn’t taken the girls long at all to find the one thing nearby that was actually flammable.

“I know, they’ll be great,” said Spike. “Still, though…” he whistled. “Eighteen kids. I could not handle that.”

“What can I say?” said Twilight. “I had two wives - or four wives, depending how you count it - pushing me to sire the biggest brood possible. Be thankful Ember isn’t putting that kind of pressure on you.”

Spike chuckled. “Oh, don’t be so sure about that,” he said. “She’s already been talking about… more. I could barely get her to let me go, and I’m almost afraid of what she’ll do when I get back…”

Twilight nudged Spike in the ribs. “Sounds like fun! We’ll see how judgy you are when you’ve got eighteen little monsters constantly getting themselves into trouble.” She squinted, focusing her eyes on the gathered children, and created a magical barrier around then just before they managed to ignite a royal banner.

“Were these things always this boring?” asked Gossamer. “Seriously, I do not remember the Gala being this dull last year.”

“I think this is just the first year we’re actually being expected to be proper,” said Flare Dancer. “Like, last year it was still, ‘oh look at the little princesses in their little dresses, ooh they’re getting into the cake, so cute.’”

“Yeah,” Midnight Satin agreed. “Last year we were just kids. Now we’re, like… the future of Equestria. People wanna know what kind of princesses they’re getting.”

“You are quite right, girls,” sighed Nightmare Moon, moving in to cast a shadow over the fillies. “I apologize, I could not help but overhear. Yes, dears, I’m afraid this is the reality of life in the court. Appearances and manners are paramount, and…” she sighed deeply. “Yes, it can be very tiresome. If it is any consolation, I am putting in an appearance against my wishes as well; I would much rather to leave things to Luna.”

“So we’re gonna have to do this all the time, huh?” Gossamer asked.

“It will become routine eventually,” said Nightmare Moon. “Some of you may even grow to enjoy this courtly schmoozing. And if not, there is always fun to be had in gossiping about all these tiresome ponies once the evening is over. Just be patient until then, and know that I am suffering alongside you.”

Nightmare Moon gave the girls a conspiratorial grin, and the three of them returned the smile. But a pair of stallions - young, finely dressed, wine glasses in hand, seized upon this moment of connection to pull Nightmare Moon away from her daughters.

“Can you believe it,” said one of the stallions, a pale yellow earth pony. “It’s Nightmare Moon! Never dreamed I would see you in the flesh.”

“We wanted to get a moment with Princess Luna-” said the other stallion, a deep blue unicorn. “But you might be an even better get! Equestria is only just getting to know you as something other than a conquering terror, and so few ponies have had the opportunity to speak with you!” He glanced down at the fillies, and let out an awkward laugh. “Maybe the little princesses should run along? Just in case the conversation goes in an after-dark sort of direction?”

Nightmare Moon nodded ruefully, and the girls “ran along,” grumbling all the while. They found themselves a spot by a wide marble pillar, where they had easy access to a table full of food but were largely hidden from anyone who’d try and talk to them. They also had a good line of sight on Nightmare Moon, and they watched their mom at a distance - all three commiserating with their mother’s torment at the hands of the two stallions.

Of course, the stallions weren’t trying to make Nightmare Moon miserable. High-society schmoozing was probably their favorite thing in the world, and maybe - to a receptive audience - they were delightful. But the girls could tell that these stallions were what Nightmare Moon referred to as “stuffed shirts,” and it was obvious that their very presence was aggravating to her nerves.

“Are you seeing this?” whispered Flare Dancer. “Mom’s already at her limit! I don’t think I could get her this mad if I tried, and these guys are doing it like it’s nothing.”

Gossamer laughed. “And these guys look like they’re having fun! I mean, Mom’s like, not even doing a good job of keeping her cool. Can’t they tell?”

“Must be pretty drunk,” said Midnight Satin. “Or pretty stupid! Both, maybe? Ponies are supposed to be scared of Nightmare Moon, and these guys are about to make her snap!”

“Yeah,” laughed Gossamer. “These two ding-dongs are gonna kick off a thousand years of darkness, just by being annoying. Mom’s gonna hurl ‘em right into the nightmare zone or whatever, then start rampaging all over…” she paused, watching her mother’s eyes go darker and her mane turn into a deeper, darker veil of night. “Uh, am I wrong, or is Mom, like, actually about to snap?”

Flare Dancer winced. “Yeah,” she said, “I think we might have to go over there and… save those idiots’ lives.”

Across the room, Nightmare Moon was clenching her fists and gritting her teeth as the stallions jabbered on. They had her cornered - a position she did not enjoy being in - and they seemed completely oblivious to her growing rage. Was this what she’d worked for, all throughout the past decade? Rehabilitating her image, gradually making more appearances in public, trying to get ponies to be less afraid of her… and now, she was seeing just what it meant for ponies to not be afraid of her. She was remembering why she’d wanted ponies to be afraid of her, all those centuries ago. Maybe a little wrath - just a little - would set things right. And who deserved it more than these two chumps? She sent a surge of magic up the length of her horn, ready to plunge-”

“Mommmm!” whined Midnight Satin, tugging at Nightmare Moon’s skirt. “I spilled punch on my dress! Help me?”

Her daughter’s voice brought her wrath to an abrupt halt; the growl that had been building in her throat turned to a sigh when she saw the cherry-red stain on the front of Midnight Satin’s white dress. “Excuse me, won’t you, gentlemen?” she said. “Midnight Satin requires my assistance.”

The stallions excused themselves, still heedless of the danger they’d just escaped. Nightmare Moon led Midnight Satin into the shadow of a pillar, priming her horn to cast a stain-removal spell, already starting to forget what she’d been so angry about. And Midnight Satin sighed, still not happy that she’d been the one who had to embarrass herself for this little distraction.

“Okay, hang on,” said Freshwater. “Daybreaker is a different person than Celestia? Or isn’t she?” He shifted on the couch, fidgeting with the hem of his shirt. “Because I really thought I understood it before, and I’m starting to think I really don’t.”

“That’s on you! I did a great job explaining it,” said Ruby Flames. She was seated on the opposite side of the couch; she would have liked to be sitting closer to Freshwater, but getting caught like that might put the poor colt in hot water. “They’re in the same body, but they have different personalities, and they transform back and forth. Simple!”

“Ohhhh,” said Freshwater. “So like a werewolf!”

Ruby Flames grinned. “Yes! Exactly!”

“So why didn’t you just say that?” asked Freshwater. “You could have just said ’my moms are werewolves’ and I would have understood 100%.”

“Well, two of them are,” said Ruby Flames. “I mean, four of them are, in two bodies.” She sighed. “Ugh, it is impossible to talk about this family.”

“Okay, so I was right to be confused,” said Freshwater. “So I met Celestia last time, and now Daybreaker wants to talk to me? What’s that going to be like?”

Ruby stood from the couch raising her voice almost to a shout. “It’s going to be terrifying!” she declared. “There’s no other way to put it, Freshwater - Daybreaker is the evil version of Celestia! She’s a ruthless conqueror who wants torture all of Equestria with-“ her lips started to twitch upwards, and she barely stifled a laugh as she continued. “-the heat of the blazing sun! If she senses weakness-“

“Ruby. Flames.” said a voice from the guest room’s doorway. Freshwater twisted his next to look behind him, and saw a towering figure with a bright, fiery mane. “Why are you trying to frighten Freshwater? You are about to go on your third date with him - I should think this means you like him.”

Ruby Flames’ jocular confidence abruptly shriveled up at the mention of the world like. “We’re just joking around, Mom,” she said, a red blush spreading on her magenta cheeks.

“Of course,” said Daybreaker. “Could I have a moment alone with the colt? I won’t keep you apart for long.”

“Sure thing, Mom,” said Ruby Flames. She left the room, sing-songing “Good luck, Freshwater…”

Ruby closed the door behind her, and Daybreaker crossed the room at a leisurely pace. Freshwater watched her move, trying to keep his cool - trying not to gape openly at the sight of Daybreaker. She was different from Princess Celestia, whom he’d briefly met before his last date with Ruby Flames. He hadn’t realized that she would be bigger, or that she would have muscle definition that Princess Celestia’s lithe figure lacked. The dancing flames of her mane and tail weren’t a surprise, but he felt their heat on his skin as she passed by him - and he began to wonder if he really did have something to be afraid of.

Daybreaker took a seat where her daughter had just been, and Freshwater felt the couch shift from the Amazonian mare’s mass. He nervously cast an eye towards the points where her mane and tail touched the couch, half expecting the blaze to spread - but it stood to reason that Daybreaker didn’t go around setting fire to everything she touched. Reassured, he turned his head slightly and made eye contact with Daybreaker - and tensed up again, suddenly fearful that her focused gaze would set him aflame.

“So,” said Daybreaker. “Freshwater.”

These words hung in the air for a moment.

“How would you describe your intentions for my daughter?” Daybreaker continued.

Freshwater was once again silent, doing rapid and futile calculations in his head. He would have loved to know the right words to say to Daybreaker - if, indeed, there was a series of words that would de-escalate the situation. But he simply didn’t know enough about Daybreaker to figure out what to say. Honesty seemed like the safest option, but even that path was fraught. If he didn’t phrase the truth in precisely the right way, who knows what kind of...

And at the same time, Daybreaker was processing the situation from her end. She’d already fucked this up, hadn’t she? All she was trying to do was have a friendly conversation with her daughter’s coltfriend, but she’d scarcely said a dozen words and the poor kid already looked terrified. “What are your intentions for my daughter” seemed like a perfectly innocent question when she’d formulated it in her head… but from the way Freshwater was reacting, it was as though she’d pressed a knife to his throat.

“Calm yourself,” said Daybreaker. “I am not accusing you of anything. And a colt of sixteen hardly presents a threat to the royal family, whatever his intentions. Our intelligence team already looked into your background and found nothing to worry about.”

“Oh,” said Freshwater, “You did a background check on me?”

Daybreaker groaned internally. Of course that would not have soothed the colt’s nerves. “The important thing is, we found little reason to worry. Unless, of course, you are not the Freshwater whom we investigated. I suppose there could always be a rogue faction of changelings, infiltrating the castle in the guise of a young suitor… a very clever way to use my daughter as a weapon against me.”

“W-what?” stammered Freshwater. “N-no, I promise! I’m just… me!”

“Oh… forgive me, I was simply thinking out loud,” said Daybreaker. “I am vigilant to a fault, they tell me. I frequently think about potential threats to me and my family, and... I should have known better than to vocalize them.” She took a deep breath, refocusing herself. “I did not intend to unnerve you with conspiratorial flights of fancy, young stallion. A hormonal teenager such as yourself is likely to do nothing more dangerous or sinister than simply impregnating her.”

Freshwater’s sky-blue face paled until it was nearly bone white, and Daybreaker placed her head in her hands. She was trying - she really, truly was.

Chapter 6

“Your Highness!” said Pinkie Pie, waving down Daybreaker beside the DJ booth. “Thank you so much by trusting me with your daughters’ eighteenth birthdays! This was a big get for me!”

“A get?” asked Daybreaker incredulously. “You are the most famous party planner in Equestria, and a personal friend of Twilight Sparkle. Were you concerned that we would go with someone else?”

“I dunno!” chirped Pinkie Pie, making a broad gesture that caused her champagne flute to spill. “Sometimes I worry! I can’t be happy-go-lucky all the time, Princess!” She squinted at Daybreaker, examining the princess’ flowing, flaming mane. “So… what’s your deal, Daybreaker? You’re, like, some kind of burning muscle mare?”

Daybreaker scoffed, holding back a smirk. “Pinkie Pie, you have asked me that question nearly every time the two of us have spoken.” She squared her shoulders and answered solemnly: ”My answer is unchanged: yes, I am ‘some kind of burning muscle mare.’”

“Cool!” said Pinkie. “So… all those kids are heading off on their own adventures tomorrow, huh?”

Daybreaker was silent for a moment before answering. “Yes,” she said. “Not all of them are leaving tomorrow, for various scheduling reasons, but they will all be moving on… quite soon.”

“I wish one of them would have come to me for an apprenticeship,” said Pinkie. “Equestria could use a princess who knew her way around baking, party planning… fourth wall stuff…” Pinkie turned her head a few degrees and winked at a bare section of the wall. “If one of them ever gets bored with her ‘adventure,’ maybe send her my way!”

Daybreaker hadn’t been listening very closely to what Pinkie Pie was saying, but she responded by noncommittally mumbling, “Yes, of course… wonderful idea…”

Pinkie sensed that Daybreaker was checking out of the conversation. She was just about to excuse herself, but Daybreaker beat her to it; the burning princess demanifested, leaving Celestia in her place.

“Ah, hello, Pinkie,” said Celestia. “Just a moment…”

Celestia tugged at her dress, tugging and tightening the waist and neckline. Her dress - as well as Luna’s - was a miracle of practical design, perhaps Rarity’s greatest technical accomplishment. It fit Daybreaker snugly, hugging her broad chest and muscular thighs - and when she turned back into Celestia, it hung loosely without appearing to be ill-fitting. Truth be told, it wasn’t as good as wearing a dress that was properly tailored for one body or the other, but it was a decent compromise for social events where both the princess and her alter ego wanted to be present.

“There we are,” sighed Celestia, after she’d gotten the dress to fit comfortably. “I do wish Daybreaker would retreat to a more private space before ceding control to me. It is embarrassing, and just a bit immodest, to adjust my dress in the middle of a party…”

“Don’t worry, Princess!” said Pinkie Pie. “I didn’t see anything I wasn’t supposed to! No royal nip slips or anything like that. So why’d Daybreaker just split like that? Did she have to run off to the little girls’ room?”

“Er… no,” said Celestia. “I am not sure how you think our dual identity works, but the scenario you’re describing is not necessary or possible.”

“Well, I hope I didn’t say anything that cheesed her off,” said Pinkie.

“No, not exactly,” said Celestia. “She is just wistful over the impending departure of our daughters, and she is somewhat tight-lipped when it comes to emotional topics. I am just as wistful, I confess. Just a bit less inclined to scamper off when the conversation turns… challengingly personal.”

“Ooh, savage!” laughed Pinkie. “I wish I had an evil counterpart to gossip about. She’d be named Bad Pinkie and she would be a messy bitch!”

Celestia cracked a smile, but Pinkie could see that she wasn’t in the mood to riff on the “Bad Pinkie” concept - so Pinkie steered the conversation elsewhere. “Hey, it’s only natural to feel this way. Your kids have been a huge part of your life for the last eighteen years! I thought this might happen, which is why I chose this hall for the celebration. The interior space-“ she gestured widely with both arms- “is for jubilant celebration, and that quiet little garden-“ she pointed at the tall glass doors that led outside- “is perfect for quiet contemplation.”

“In faaaact,” she continued, “I’m Pinkie Sensing that if you go out to the garden right now, you’ll run into two other mares who share the same feelings and might be willing to talk about it!”

Celestia tilted her head. “Is that another thing your Pinkie Sense does?”

“Nah,” said Pinkie. ”I just sawLuna and Twilight walk out there a second ago.” She giggled. “Sight isn’t the Pinkie Sense, but it is a Pinkie sense!”

Celestia thanked Pinkie Pie and made her way to the door, stepping out into the cool and quiet of the royal garden. Celestia couldn’t see Luna and Twilight from the doorway, but she wasn’t in any rush; the calm darkness was a welcome respite from the crowded and noisy party. She strolled between the tall hedges, admiring the flowers in the dim light, until she turned a corner and spotted her wife and her sister. Twilight and Nightmare Moon were seated on a bench by the reflecting pool, Twilight tucked under Nightmare Moon’s wing.

There was a time when Twilight Sparkle could have fit easily under Nightmare Moon’s wing; the Mare in the Moon’s Amazonian stature came with a huge wingspan, big enough to completely conceal an average mare. But Twilight had done a lot of growing in the last eighteen years; she stood taller than Celestia now, a fact that had surprised and amused both of the royal sisters. No one quite knew what influenced the growth of alicorns - there simply weren’t enough alicorns around to do a proper study - but Twilight’s wives were very happy with how she was turning out.

Celestia approached and sat herself down on the other side of Twilight, scooting in until she was just as close as her sister. “Taking a break?” she asked.

“Yeah,” said Twilight, turning her head just enough to make eye contact with Celestia. “The girls don’t need us around every second. This party’s for them and their friends, and they should…” she sniffed, then continued: “they should have fun.”

Celestia put her arm around Twilight’s shoulder, pulling her a little closer - but not so close that she stole her away entirely from Nightmare Moon. “Twilight Sparkle,” she said, “can I confess something? I’m feeling rather misty about what the next few days will bring. That many goodbyes all at once… I truly don't know how I will hold it together.”

“Well,” said Twilight, sniffling once again, “you won’t be the only one crying, so don’t worry about that.”

“The two of us came out here so as not to embarrass the girls,” said Nightmare Moon. “If their friends saw me blubbering openly, I fear it would be widely regarded as a ‘bummer.’”

“And it would do your reputation no favors,” said Celestia.

“Quite,” Nightmare Moon agreed. “I don’t feel the need to be feared quite so much lately, but I would prefer not to be pitied.”

“Yes, I-” Celestia paused. “Pardon me, but Daybreaker is trying to cut in. I’d prefer to remain a part of the conversation, however… one moment.”

With a bit of focus, Celestia transformed herself into her hybrid form - a rarely-used compromise between the physical bodies of herself and her alter ego. “I should do the same,” said Nightmare Moon. “Luna is letting me know that she wants to be present, and I am certain she will give me a hard time if I don’t permit it…”

While Nightmare Moon transformed into her hybrid body, her sister once again tugged at her dress. “Oddly enough,” she grunted, “This dress is much more comfortable when I am either Daybreaker or Celestia. Being in between just makes it feel wrong all over.”

“Yes,” said Hybrid Moon, trying in vain to straighten her dress’ neckline, “We are finding this to be the case as well. I suppose we can put up with a small inconvenience, if it means all of us can be here.”

“Yes, we should all be here,” said Twilight. “It sounds like we’re all in the same boat, huh?” sighed Twilight. “I always tried to make sure we were prepared for everything when it came to parenting. And we usually were! I mean, we weren’t perfect, but… nursing, language development, reading, school, puberty… we were as ready as anyone could be! But this… the girls going away… I feel completely blindsided.”

“I remember feeling like this when I sent you away,” said Hybrid Sun. “A feeling that I was losing something I couldn’t get back. I knew that you needed to begin the next part of your life... But it didn’t feel right for things to change just yet.”

“We have lived so long, and seen so much,” said Hybrid Moon, “ you would think we would be less prone to sentiment when we see things change. But how dull that would be! To never feel the weight of loss or mourn the passing of time. We would not be fit to lead or to love, if we no longer felt as ponies do.”

“I’d like to feel just a bit less of this weight,” said Twilight. “Or if I could deal with it better. Be a little less overwhelmed.” She shifted her weight, leaning a little more of it onto Hybrid Sun. “I guess I know how you felt, when you let me go,” she said. “But I saw you sometimes, and I always sent letters… and eventually I came back!” She sighed, slumping more of her weight against Hybrid Sun. “But that’s not quite how it works out with kids, is it…”

“No,” said Hybrid Sun. “I would be overjoyed if each and every one of them returned here and joined the ‘family business,’ as it were, but it is out of our hands! We must accept that their lives are their own, and simply hope…” she paused, her expression shifting. “Oh, I simply don’t have it in me to be the wise, detached mentor right now! I wish our daughters were not leaving! I am not ready for it, and there is no wisdom that will change the way I feel! Nor would it change your feelings, I suspect!”

“You are right,” said Hybrid Moon. “The girls will leave, and we will cry openly, and the castle will feel very empty for a time. I do not know if there is any way to prepare for that, other than simply knowing and accepting that it will happen.”

“I hate that answer,” said Twilight. “But you’re right.”

Having come to that agreement, the princesses were quiet for a while, watching starlight ripple on the surface of the reflecting pool. Finally, Twilight spoke again: “But they’ll be okay, right? I mean, that’s what really matters. They’ll be fine out there, right?”

“They know how to defend themselves, if that’s what you mean,” said Hybrid Sun. “None of them are headed anywhere especially dangerous, but we’ve trained them in an array of defensive magic if they run into danger.”

“And they have had many years to practice those spells,” said Hybrid Moon. “Perhaps too many, since Nightmare Moon and Daybreaker went behind everyone’s backs to teach them those spells at an irresponsibly young age.”

“Oh, there was no harm in that,” said Hybrid Sun, drawing on her Daybreaker side. It was cute to see them running around shooting those magic bolts out of their horns. It barely hurt at all to get hit by one, really.” She paused in contemplation. “They did knock over quite a lot of vases, though.”

“The magic bolt wasn’t that bad,” said Twilight. “The real mistake was teaching them the shield spell too early. Golden Shield was convinced she’d be the best at it, and she kept daring the other girls to throw rocks as hard as they could at a bubble that could maybe stop a paper airplane.”

Hybrid Moon laughed. “We are lucky that none of them had much of a throwing arm at that age.”

“We were luckier than my parents were,” muttered Twilight, through a thin, mischievous smile. “My brother was a genuine prodigy when it came to shields, and he had me hurl rocks at him too. I didn’t have much of an arm either, but after he egged me on enough, one lucky throw cracked his shield and left a huge bruise on his shoulder. So…” she nudged both sisters with her elbows. “If you’d come to me, I could have told you exactly how bad an idea it was to teach the girls those spells.”

“Anyway,” said Twilight, “I’m not that worried about physical danger. I was lucky to find the friends I did, and meeting people like Starlight showed me that not everyone is so lucky. I just want them to make friends, wherever they go.”

“And they won’t have you around to help anymore!” said Hybrid Moon. “What a pity. I remember when Radiant Sunrise was having difficulty making friends in the fourth grade, and you intervened to assist her… you won’t be able to do that now that they’re on their own.”

“Oh yes,” laughed Hyrbid Sun, “Sunrise was just delighted to have the Princess of Friendship arrive in her humble classroom to teach a surprise lesson. I hear you were very subtle back then.”

“Oh, don’t remind me of that,” groaned Twilight.

“Why not?” laughed Hybrid Moon. “It’s still an option! If one of our daughters is having a friendship problem, just teleport to wherever she is and insert yourself into her life!”

“Right,” sighed Twilight. “Don’t worry, I learned my lesson. And I suppose we’re sending them out into a better world than the one I went out into,” said Twilight. “We have better foreign relations and fewer villains, so that’s something.”

“Yes, far fewer villains,” said Hybrid Moon.“Although… the third royal sister is still out there somewhere…”

Twilight sat up. “Hm?”

“Oh, yes!” said Hybrid Sun, not missing a beat. “The secret third sister, who was so evil - a thousand times more evil than you, Nightmare Moon - that we expunged her name from the history books before we sealed her away. Yes, yes, someone’s going to have to deal with her at some point. I hope that burden doesn’t fall on our poor progeny…”

Twilight groaned. “I actually believed you two for a second there. You know, it’s not fair for both of my wives to gang up on me like that.” She relaxed onto the bench again, snuggling up to both royal sisters. “Well, I’m not worried. If the girls run into a secret third sister, I’ll marry her too and knock her up with nine foals of her own. It’ll be great.”

“Oh, without a doubt,” said Hybrid Sun. “We made the best of motherhood, against impossible odds, on our first try. The next time, we shall glide effortlessly through it no matter how many foals there are.”

“Oh, she hasn’t worn this in ages,” said Twilight, pulling a polka-dotted dress from Summerfree’s closet. “There’s no way it still fits, but she’d kill me if I threw it out without her permission.” She pulled it off the hanger, folded it up, and set it in the cardboard box on Summerfree’s bed. “She probably wouldn’t even let me look through her closet if she was still here...”

Twilight sighed. She’d been putting off the task of tidying up the girls’ bedrooms; it was just another reminder that they were all moved out, and she could only contemplate that for so long before she began to get choked up. After she was done with Summerfree’s room, she’d probably need to distract herself with something...

She turned back to the closet and sorted through the hanging clothes. “When did we buy her all these shirts?” she muttered. “How does she have more clothes than her sisters? Not like we ever played favorites when it came to clothes.” She took another hanger from the closet and stared at it. “No, this was Amaranth’s… I guess Summerfree’s been borrowing clothes. Well, that’s between her and…”

Twilight noticed something out of place - the dangling corner of some colorful, glossy paper, tucked under a shoebox on the closet’s upper shelf. She lifted the shoebox and pulled the paper out from under it, taking a look at what was printed on it.

“Oh,” said Twilight, her face falling. “Well, she’s basically a grown mare now… I mean, it’s healthy… normal… and it’s not my place to tell her who she should be… interested in…”

Sighing, she lifted the shoebox and tucked the paper underneath it, making sure that no corner was poking out this time. She went back to sorting Summerfree’s clothes, but she couldn’t quite get that image out of her head.

When had Trixie ever posed for a pinup? Had she gone off and become a sex symbol while Twilight had been focused on parenting? And how had Summerfree gotten her hands on a poster of Trixie Lulamoon, provocatively posed, wearing nothing but her signature hat and cape?

Twilight paged through her notebook, tracing her finger over the neatly drawn sigils. Over the past two decades, working on the conception spell had been a hobby of hers; whenever she got the chance, she would read up on fertility spells and reproductive health magic, looking for any way to refine and improve the spell. And throughout all those years, she’d done a lot; this time things would be a lot more fun.

“It’s somewhat rare for you to insist on a particular set of partners, Twilight,” said Daybreaker as she let the bathrobe fall from her shoulders. “What made you decide you wanted me and Nightmare Moon this evening, my darling?” She approached Twilight, gently pulling at her bathrobe. “I would like to think that my efforts at seduction are paying off. I’m sure you’ve noticed me slutting it up lately. I spent a while moping about after the girls moved away, but there are advantages to having the castle to ourselves.” She arched her back, thrusting her tits in Twilight’s face and shooting her a saucy grin. “I may be a little rusty, but my body is still perfect! Just one advantage of being ageless.”

“Yes,” said Nightmare Moon, emerging from the steamy bathroom. “As good as our sex life has been, I now realize how much I’d been holding myself back for the kids’ sake. It’s fun to shake my tits for you in front of the staff… or grind my bottom into your lap while you’re sitting on the throne... “ she laughed triumphantly. “Oh, the girls would be mortified if they saw their mothers acting like that.”

Twilight cracked a smile. “Girls… I think it’s the perfect time for something I’ve been putting off. I’ve been putting it off for the last two decades, actually, and I just can’t wait to let you in on it.”

There was something sinister in Twilight Sparkle’s voice - a rare occurrence, unusual enough that it made both of the royal sisters slightly nervous. “Just what are you proposing, Twilight?” asked Nightmare Moon.

“I have something for the two of you that is long overdue,” said Twilight, her smile growing wider and sharper. “I certainly couldn’t do it right away, not when the two of you were pregnant… and then when the girls were infants, we were all so busy, and then there was school, and… well, at any rate, the time has come, ladies.” She let her own robe drop to the floor. She wasn’t the same mare she had been twenty years ago; throughout two decades of life as an alicorn, she’d gradually grown in height and muscle mass. Not quite as big as Luna and Celestia’s alter egos - but still an imposing presence when she wanted to be. “It’s time for your long-overdue punishment.”

“O-oh?” asked Daybreaker. Twilight’s confidence and cruel smile were making her knees tremble; Daybreaker adored power, and she was a conqueror by nature, but Twilight's promise of punishment brought out the submissive in her.

“Yes,” said Twilight. “Did you really think your little pregnancy stunt would go unpunished forever?” she shook her head and clucked her tongue. “That was a serious breach of my trust. Believe me, I know the value of forgiveness, but after a betrayal like that… well, there can’t truly be peace between us until the score is settled. So take your place on the bed, and do not resist me… and I will punish my wives until I decide they have had enough.”

Nightmare Moon was already on the bed, and she stayed there - but Daybreaker hesitated for a fraction of a second. Twilight stomped her foot, hard enough to shake the chandelier hanging from the bedchamber’s ceiling. “NOW!” she bellowed, at a volume that put the Royal Canterlot Voice to shame. Before she could even think, Daybreaker was scrambling onto the bed, obeying her wife’s command - and she felt a heat awakening in her core. She couldn’t remember the last time she’d gotten turned on so quickly…

“There we are,” said Twilight Sparkle, sauntering over to the bed. “Don’t resist, my darlings. I need you to show me that you love me… and serve me… and the way you’ll do that is by being grateful for your punishment.”

Twilight threw herself onto the bed, bouncing and settling between her wives. She reached her arms out in opposite directions, resting her fingers in each mare’s collarbone and tracing a path down to their breasts. “You two made a terrible mistake, going behind my back like that. Didn’t you realize that I would grow in power?” She pinched their nipples - at first she was gentle, but then she twisted them mercilessly, making both mares cry out in pain. “You knew what a good student I was… how quickly I grew stronger. You knew I would become the most powerful princess in Equestria.”

Twilight sprang up on the bed and crawled atop Daybreaker, hovering her face just inches above the other mare’s. “And you didn’t just know it… you wanted it. This was what you wanted the whole time, wasn’t it? To create an alicorn who would be greater than you. Someone who could overpower you… dominate you. Well, now you have me.” She paused, licking her lips. “Well, it’s more like I have you.”

She kissed Daybreaker, forcing her tongue past the mare’s lips and reaching down to grope her asscheeks. Daybreaker was completely unresisting now; every motion of Twilight’s tongue, every rough squeeze of her fingers, made Daybreaker’s marehood pour with arousal.

Nightmare Moon wasn’t happy with just watching, though; growing impatient, she sat up on the bed and reached out her hand to caress Twilight’s mane. To her shock, Twilight tensed and threw herself off of Daybreaker, pouncing on Nightmare Moon in an instant.

“I told you to lie on the bed,” growled Twilight, snarling cruelly at Nightmare Moon. “See, this is the problem with you naughty girls. Just like twenty years ago, you always give into your selfish impulses. You do what you feel like doing, instead of what I tell you to do.” She leaned in for a kiss - just as forceful as the one she’d given Daybreaker, but much briefer. “How am I supposed to rule Equestria if I can’t keep my wives under control? I need everyone to see that I am the mightiest princess… the greatest among us… and it all starts right here, in this bedroom.” She reached down with one arm, following the curve of Nightmare Moon’s pelvic bone until her fingers were achingly close to her pussy. “You will do what I command you to, from this point forward. Because that’s what a good wife does… and you want to be good, don’t you, Nightmare Moon?”

Nightmare Moon groaned. Her pussy was begging for Twilight’s fingers to come just a little bit closer, to touch and explore her slick marehood. She would do whatever it took for Twilight Sparkle to give her release… “Yes, Twilight… I want to be good… I’ll do what you want…”

“There!” said Twilight happily. “That’s what I’m good at. I take villains like you, ponies who nobody thought could be redeemed…” Twilight’s horn glowed, and a line of magical energy extended from Twilight’s hand and strung itself around Nightmare Moon’s neck, forming itself into a collar.

“...and I tame them.” Rolling off of Nightmare Moon, Twilight extended her arm in Daybreaker’s direction and gave her a similar collar. “All those sinister desires and naughty instincts… I break bad girls like you. Hands and knees, girls!” She yanked on the collars, jerking Nightmare Moon and Daybreaker upwards. Obediently, the two of them got on their hands and knees, trembling in anticipation.

“Good!” said Twilight, demanifesting the collars and resting her hands on their bare backs. “The first step on the road to redemption. Once I turn the two of you into good girls, you’ll be a shining example to the rest of Equestria.” She scooted backwards on the bed, gliding her hands along her wives’ muscle-bound backsides until her hands found their glutes.

“Lots of ponies are still scared of you,” said Twilight, “but when they see you tame and broken before me, they’ll know it’s me they should be afraid of. All your strength, all your ambition - it belongs to me, girls. It serves the might of Princess Twilight Sparkle, the ruler of Equestria! So tell me, girls - who is your princess?”

Before they could answer, Twilight raised her hands and brought them back down in a loud, resounding smack. “You-you are!” the sisters answered.

“That’s absolutely right,” said Twilight. “I’ll make loving, devoted wives of you two yet… and then all of Equestria will love me the way you do. You can lead the adoring crowd in cries of ‘Praise Twilight!’ Won’t that be nice?”

She smacked her wives’ bottoms again, and they cried out “Praise Twilight!” in near-perfect unison. “Yes, exactly!” cackled Twilight. “Doesn’t it feel good to praise your princess? Doesn’t it just fill you with powerful, aching pleasure when words of praise pass your lips?” She smacked their asses again, and once again they praised her name. “Yes, that feels better than being bad, doesn’t it, ladies? Giving in to selfish desires - defying me - might give you a momentary thrill… but serving me and praising my name will fill your life with pleasure beyond imagining.”

Twilight manifested magical force around her fingers, turning both hands into wide, aerodynamic paddles. She smacked her wives’ asses repeatedly, mercilessly, barely giving them time to say “Praise Twilight!” before she swatted them again.

“You seem to be getting the idea,” said Twilight. “I’m still watching you two for the slightest hint of defiance, but this is a promising first step. I think my good girls have earned a treat.”

Twilight formed a circle with the fingers of both hands and placed it on her crotch. Her horn glowed, and the interior of that circle shone with the same purple light - and a thick purple stallionhood began to manifest on her body. She caressed the growing shaft, letting her hands follow its growth all the way to the tip.

“Well, it’s not so much a treat as it is another implement with which to administer punishment,” said Twilight, “but if you show proper reverence, and submit to Twilight Sparkle’s gorgeous, immense cock… you might just end up enjoying this.

“Now then… Daybreaker, you’ll attend to me first. Nightmare Moon, I expect better behavior this time. Do not insert yourself into the proceedings… and do not touch yourself. My wives may only feel the pleasure that I give to them, and they cum when I permit it.

“Daybreaker,” said Twilight, “you’ll use your mouth to get my cock nice and slick, all right? Feel free to enjoy yourself.” She hopped down and stood at the foot of the bed, thrusting her hips to make her flaccid cock bounce enticingly.

Daybreaker wasted mo time carrying out Twilight’s order. She grabbed her wife’s shaft with both hands and lay her tongue against the underside, licking her way upward and drooling all over Twilight’s towering stallionhood.

“Ahh… not bad…” moaned Twilight, running her fingers through Daybreaker’s burning mane. “But this doesn’t earn you any brownie points, Daybreaker. You may be following my commands, but you are also slaking your shameful lust. You’re licking my cock greedily. You’re doing it for your own sake, when you should be doing it for your princess. Everything you do, Daybreaker, should be a selfless act of love for the mare who owns you, body and soul.” She shuddered with pleasure as Daybreaker’s tongue reached her tip and began to wet the wide, flared head. “But… that’s an advanced lesson. For now, getting my cock wet is all I ask. And… yeah, I think this is plenty. Turn around, Daybreaker, and present your cunt for me.”

Daybreaker obliged, positioning herself on her hands and knees at the edge of the bed. Twilight reached out slowly with both hands, letting Daybreaker soak in the anticipation before she grasped her rump and squeezed both of her cutie marks.

Being manhandled like that was plenty of stimulation - but Twilight intended to give her much more than that. She drew her hips in close to Daybreaker’s rump and touched the underside of her shaft against her wife’s glistening marehood. “Ooh,” she moaned, gliding her cock slowly up and down, “you’re so wet, Daybreaker. Are you going to be naughty again?” She brought both hands down on Daybreaker’s cutie marks, smacking them with open palms. “I know how disobedient you can get when you’re horny. Are you thinking about being bad?”

“No,” gasped Daybreaker. “Mistress Twilight, I only want to serve you…”

“That’s good,” said Twilight. “I can’t have you misbehaving every time you get horny, darling.” She brought the head of her cock to Daybreaker’s marehood, teasing her wife’s little pink clit. “Because I want you to be horny for me all the time, Daybreaker. I want to make you so horny that it breaks you… just the thought of me will bring you to your knees in reverence.” She thrust her hips, inserting herself two inches into Daybreaker’s pussy. “Would you like that?”

“Y-yes, mistress Twilight!” moaned Daybreaker. “Make me your slave! I want to be… mmph… good…”

“Of course you do,” said Twilight smugly. She withdrew her cock from Daybreaker’s pussy, and the fiery mare whimpered as she felt the shaft pull out. “Deep down, everyone wants to be good. Some mares just need a mistress to show them how.”

Twilight spent a short while teasing Daybreaker’s marehood, rubbing her cockhead against the mare’s clit and inserting just a couple of tantalizing inches before pulling back out. Daybreaker was red-faced, panting - she wanted to beg Twilight to fuck her, but she didn’t want to do anything that could be seen as disobedience. She bit her lip, trusting that her mistress would fuck her soon…

“All right, I’m ready,” said Twilight. “Daybreaker… I’m done with you. Tag in Celestia.”

Daybreaker almost wept. “Twilight… n-no, please just fuck me! I need it…”

“You dare defy your mistress?” bellowed Twilight. She raised her hips and brought them back down, smacking her cock on Daybreaker’s asscheeks. “I should have known you were beyond redemption, Daybreaker. Just a slave to your baser impulses…”

“N-no!” pleaded Daybreaker. “I just need you so badly… you’re my whole world, mistress…” She grunted, fighting against her own arousal - and shrank back into the form of Celestia.

“Good!” said Twilight. “This is the lesson, Daybreaker. Serve me, instead of your passions. Now then… Nightmare Moon. You’re just here to watch, got it? You will not ask anything of your mistress. I want you watching. Don’t even blink.”

“Yes, mistress,” said Nightmare Moon. She was holding up better than Daybreaker; getting sidelined was torturous, but it wasn’t as bad as getting teased. She desperately wanted to touch herself, but she balled her fists and fought the impulse; any independent action was certain to be treated as defiance.

“And you, Celestia…” said Twilight, laying a hand gently on Celestia’s rump, “I can’t tell you how much I’ve enjoyed growing into my role as a princess. You really didn’t realize, did you? You didn’t know that your little student would grow taller than you… and stronger…” She flexed her arm, admiring the taut muscle beneath her smooth lavender skin. “It’s so funny… I used to look up to you, Celestia. Figuratively and literally. But now… from where I’m standing, you’re a little shrimp.” She wrapped her fingers around the base of Celestia’s tail, gently stoking the place where it grew from her rump. “That means something, wouldn’t you agree?”

“Yes, Twilight,” whispered Celestia. Her body was tensed in anticipation, her pussy dripping with arousal. She’d been in the “back seat” while Daybreaker was in control, but now she was fully present and in command of her body She wasn’t just experiencing arousal on an intellectual level; she was feeling the heat and tension in her pussy.

It was no secret that Celestia was turned on by Twilight’s growth. She’d gleefully noted the first couple inches of growth during the initial year of Twilight’s princesshood, and year after year she’d kept her fingers crossed that Twilight would keep on growing. The night she’d realized that Twilight was a quarter-inch taller than her, she’d dragged her into the bedroom and begged to be fucked - harder, harder - to be utterly dominated by her gorgeous Amazonian wife. Celestia had never realized she wanted to be dommed by a bigger, taller, stronger mare - because there was nobody to give it to her until Twilight came along.

And once Twilight knew what Celestia wanted, she was only too happy to give it to her.

“What could it mean?” mused Twilight, sliding her fingers up and down the length of Celestia’s slit. “The way I outgrew you… I think my size and strength is a manifestation of my royal authority. I think it’s only right for the biggest princess to rule over the other princesses… don’t you agree, Celestia?”

Celestia was about to answer in the affirmative when Twilight tugged hard on her tail, simultaneously plunging three fingers into her slick pussy. The shock left her speechless, quivering on her hands and knees while Twilight probed her cunt.

“It doesn’t matter what you think, Celestia,” said Twilight. “If you said no, what would your refusal even amount to? I would use my magical and physical superiority to squash whatever little rebellion you attempted.” She gave Celestia’s tail another tug and pushed her fingers deeper. “You’d just be setting yourself up for a lengthy punishment, and the result would be the same: either way this ends with you bowing before me, praising me, giving yourself to me…” She pulled her hand out from Celestia’s marehood and wiped it on her cutie mark. “So do you want to do this the easy way, Celestia? Will you give yourself to me?”

“Yes, Twilight,” moaned Celestia. “I’m yours…”

“That’s absolutely right,” said Twilight. She placed her cock at the lips of her wife’s cunt and plunged herself into Celestia’s marehood, yanking hard on her tail. “You’re mine! Your nice round ass - your big creamy tits - your tight pussy - all mine.” She pulled back and thrust again, wasting no time, hitting Celestia’s back walls with full force. Twilight had spent many a night holding herself back, gently ramping up to full strength, only to have Celestia plead for her to go faster and harder. By now, she knew how her wife wanted to be fucked: she wanted Twilight’s cock, hard and deep, over and over until climax.

“Twilight…” groaned Celestia, “f-fuck… you’re so big… take me, Twilight… breed me, I want to feel your seed inside me… I want to bear your foals, Twilight…”

“Oh yeah?” grunted Twilight, already starting to break a sweat from the effort of pounding Celestia’s cunt. She let go of the base of Celestia’s tail and sought out a firmer set of handholds: one hand on the base of a wing, the other one wrapped around the back of her mane. “Well, you gave yourself to me so graciously, Celestia… accepted my power… and my cock…. I think I could give you the honor of bearing my foals once more.” She grunted, digging her fingers into Celestia’s cutie marks. “Don’t worry, it shouldn’t take long for me to cum… not when I’m fucking a tight little pussy like yours, baby…”

Celestia moaned louder and louder with each thrust, delirious from pleasure, her pussy relentlessly stretched by the girth of Twilight’s cock. Twilight knew how to give her exactly as much as her body could take; it took a lot to overpower the powerful, ageless Princess of the Sun, but Twilight made it look easy. Gentle lovemaking had its place, but Celestia had a growing appetite for power - more and more, she wanted to be rammed, pounded, fucked-

A shudder went through Celestia’s body. Thanks to Twilight’s rough treatment, she was only a couple pumps away from climax; she surrendered herself to the thrusting, letting her conscious mind slip away as her orgasm rose up to engulf it. Her cunt clenched around Twilight’s shaft, and she fell flat on the bed, quaking with senseless pleasure.

“Yes!” grunted Twilight. “That’s what mistress Twilight gives you - boundless love, infinite pleasure…” her hips quakes and her balls tightened against her body. “...And hot loads of potent royal cum…”

Twilight hilted herself in Celestia’s cunt, smacking her balls against her asscheeks, and moaned blissfully as her cock lurched and pumped a thick load of seed deep into Celestia’s pussy. Celestia’s marehood clenched around Twilight’s throbbing shaft, eagerly taking in each fresh splatter of Twilight’s cum. Celestia moaned with pleasure each time another warm rush of seed entered her - and when the last of Twilight’s cum oozed out of her tip, Celestia fell limp on the bed.

“There you go, Celestia,” said Twilight gently, sliding her cock out of her wife’s pussy. “Let’s see if your body can handle the seed of a true princess.” She reached down and caressed Celestia’s belly, running her fingers over the smooth skin. “Bear me strong foals, Celestia, and prove your devotion to your princess…”

Celestia responded with nothing more than a happy murmur. “Aww, did I fuck you absolutely senseless?” she teased. “Well, you need your rest if you’re going to nurture my foals. As for you, Nightmare Moon -“ she turned to the other mare, still watching obediently “-you need to get my cock hard for me again. Use those big black tits of yours.”

After what felt like an eternity of waiting, Nightmare Moon was eager to be part of the action. She crawled to the edge of the bed and knelt in front of Twilight, separating her tits to surround her lavender shaft. Twilight’s cock was still half-hard, mostly standing up by itself, and Nightmare Moon’s embrace immediately got a reaction. As Nightmare Moon bounced on the bed, she felt the shaft thickening and growing stiffer - until the head was standing tall enough that she could bend her head and lick the tip.

And once she started, she couldn’t stop - she mouthed the flared head, licking and moaning, squeezing her tits around the rigid shaft. “Oh!” exclaimed Twilight, “You were doing such a good job of holding yourself back, but it looks like you just can’t stop yourself from worshipping your mistress’ cock…” She put her hand on Nightmare Moon’s forehead, and pushed her away firmly. “But since you’ve been doing so well up until now, I won’t hold it against you. Present yourself, Nightmare Moon.”

Nightmare Moon turned herself around, lifting her tail to expose her dripping pink pussy. “Mistress Twilight,” she panted, “please… breed me, mistress, I’ve been good…”

Twilight chuckled. “You’ve been good enough,” she said, resting her hands on Nightmare Moon’s rump. “We’ve got a lot to work on, but for now… your punishment calls for a deep fucking, and your penance shall be bearing a big, strong brood for me. Are you ready?”

“Yes, mistress,” gasped Nightmare Moon. “I’m ready… punish me, breed me, I’m… giving myself to you…”

“Well, that’s good to hear,” said Twilight. She ran a finger over the pink lips of Nightmare Moon’s pussy, making her whole body quiver. “But let me just work your cunt just a little bit, just to be certain…”

Twilight circled her fingers inside her wife’s marehood, smiling at the long, lusty moans that resulted. She pressed the tip of her cock against Nightmare Moon pussy lips and gently pumped her hips, teasing the opening just like she’d done to Celestia.

“Please… mistress…” groaned Nightmare Moon, her hips bucking wildly as Twilight teased her cunt, “fuck me… fuck me… I need… nnggh!” Nightmare Moon’s whole body jerked, and she cried out as her pussy clenched. There was panic in her mind, as she realized that she was climaxing - but also relief as she experienced the long-delayed culmination. She fell limp on the bedsheets, squirming, panting, as Twilight looked on with amusement.

Celestia, awakening from her reverie, lifted her head to look at Twilight, and they shared a laugh as their eyes met. Nightmare Moon was distantly aware of this - and while she normally did not like being laughed at, the afterglow of her climax made it impossible for her to be angry. Weakly lifting herself on her shoulders, she turned to look over her shoulder at Twilight - and joined in the laughter, a blush showing on her inky-black face.

Twilight straightened her posture, taking a moment to get back into character, and addressed Nightmare Moon. “Well! Some ponies really can’t help themselves, can they? I don’t recall giving you permission to cum, Nightmare Moon. I’ll have to devise an even worse punishment for next time… but for now, Nightmare Moon, you are dismissed.”

Nightmare Moon knew what that meant. She shrank herself back into Luna - whose face still wore the red blush that her alter ego had developed. She turned her body over, lying face up on the bed; she was seductively posed, but compared to Nightmare Moon she also looked very vulnerable - almost fragile - even though she was every bit as powerful as her sister.

Twilight, of course, knew that her vulnerability was a part of how she wanted to be perceived. She didn’t share Celestia’s desire to be fucked senseless; her pleasure called for a different approach.

“It’s wonderful to see you,” said Twilight, climbing onto the bed atop Luna. “Mistress Twilight’s got you, baby…”

Twilight took a moment to simply loom over Luna’s body, overshadowing the smaller mare and dangling her big purple tits in her face. She flexed her wings, accentuating her physical superiority - but her purpose was to comfort rather than intimidate. Luna reached up to reverently stroke Twilight’s firm, muscular chest, and Twilight permitted her wife to admire her for a moment.

Twilight lowered herself onto Luna, shrouding the both of them with her wings, and brought their lips together. She dug her arms underneath Luna’s back and intertwined their legs, wrapping Luna up in herself as they kissed. The kiss was slow; Twilight locked lips with Luna and explored her mouth with her tongue with forceful, deliberate motions. Twilight held her closer, pulled her tighter, and grinded her cock against her dripping slit.

“Luna,” whispered Twilight, pulling back from the kiss and bringing her lips to her wife’s ear. “Thank you for bearing my foals, my love… you gave me such strong, beautiful children, and I’m so proud of each and every one of them. And now that our nest is empty, Luna…” Twilight paused and gently nibbled at Luna’s ear, holding the mare tight as she wriggled beneath her.

“Will you let me breed you again?” asked Twilight. “Will you bear me another litter of beautiful foals? No one but you is fit to bear the next generation of princesses…” She kissed Luna’s cheek. “Well, no one othe than your sister, but she’s already taken care of. So what do you say?”

While Luna contemplated her answer, Twilight kissed her collarbone and kept on descending. A quick kiss on her breast, a nibble at her nipple, a gentle nuzzle at her navel… and when Twilight had nearly reached her marehood, she finally got the answer she wanted. “Yes,” moaned Luna, “Twilight, make me the mother of your foals… again... “

Twilight lifted herself up and looked Luna in the face again. With a confident smile she once again went in for the kiss - and when their lips made contact, she maneuvered her hips into place and brought the tip of her cock to Luna’s marehood. She slid herself in gradually, pushing her cock forward inch by inch to the rhythm of Luna’s breaths.

“Ahh,” sighed Twilight. “That’s my girl. I’m not too big for you, am I, Luna?”

“No…” moaned Luna, “no, you’re perfect…” she arched her back, thrusting her hips upward and taking Twilight deeper. “I love you, Twilight, I need you, I need to be a vessel for your seed…”

Twilight smiled, meeting Luna’s eyes as she pumped her hips slowly and rhythmically. Each thrust took her deeper into Luna’s marehood, and Luna’s happy sighs gradually rose in volume, becoming lusty moans - and then full-throated cries.

“Twilight!” she gasped, between thrusts. “I’m ready, Twilight… I want to be a mother again. I need to… feel your seed inside me… to nurture your foals, and grow heavy with new life…”

“Well, if you’re ready,” said Twilight, accelerating the pace of her thrusts. “If you just can’t wait to become a mother again…” She put her hands on Luna’s lower back, pulling her closer, and kissed her again.

Twilight could feel the pulsing in Luna’s marehood, the signal of oncoming climax tightening all around her cock. Twilight pumped harder, faster, feeling her own climax building in the base of her cock.

Twilight’s balls were more than capable of giving Luna what she needed; her magic stallionhood was a flawlessly engineered delivery system for a generous volume of potent seed. It was also a perfect implement to pleasure, just the right size to push her wives’ marehoods to their limit and give them an Earth-shattering climax…

Through their joined lips, Twilight felt Luna’s moans rising in intensity. Twilight broke off the kiss just as Luna’s climax struck, and Luna called out Twilight's name as it swept over her. Satisfied, Twilight decided to finish herself off, pumping recklessly until she felt her cock lurch, throb, and erupt.

Both mares came together, Twilight’s cock providing a princess-sized load and Luna’s pussy greedily taking it in. Luna’s body had felt such need, and the rush of cum was quenching that need and leaving pure satisfaction in its place. Her arms released Twilight as their climaxes cane to an end, and she fell limply into the bed. Twilight pulled herself out, dripping cum onto the rumpled bedsheets, and lay herself down between her wives.

“So,” said Twilight, “I didn’t want to ruin the mood by nagging you while we in the middle of things, but… did you both manage to cast the fertility spell?”

Luna and Celestia affirmed that they had.

“Good,” said Twilight. “The changes I made should have made it simpler to cast... but I have a bad habit of designing spells that make sense to me, but aren’t all that clear to other ponies. So I was worried…” she coughed awkwardly. “Well, anyway, I’m glad that went smoothly. Now we just have to do… the rest of it. The next eighteen years. Honestly, I think I’m more anxious than last time. I mean, the first time we knew it would be hard, and I was willing to cut us some slack if we weren’t perfect. Now that we’ve raised kids already, I’m thinking to myself… what if we do a worse job this time? What if we don’t meet our own standard?”

She sighed, taking a moment to calm herself. “I shouldn’t be that worried,” she said. “I mean, this time we’re not going to have nearly so many kids…”

She paused, leaving space for Celestia and Luna to respond - but instead they stayed silent and exchanged guilty-looking glances.

Twilight groaned and rolled her eyes. “All right,” she said. “How many?”

Chapter 3

“Are you excited, my love?” asked Princess Celestia, laying a hand on Twilight’s thigh.

Twilight Sparkle’s hesitation made it clear that the answer was something other than an unqualified yes. For a mildly awkward moment, she sat in silence between her two wives as the carriage rumbled along the cobblestones.

“Well, if nervousness counts as a type of excitement,” Twilight finally said, “then… yes! I'm excited for this checkup. mostly I just want to hear that everything’s all right, so that I can finally relax.”

Princess Luna sighed, smiling gently. “Twilight, you must not focus so much on what can go wrong. Today you will hear the heartbeats of the foals you sired. Think of how it will feel when their strong hearts speak to you, my darling.”

Celestia nodded. “There will always be things to worry about, Twilight. Doubly so when one is a parent. But allow yourself to set those worries aside, and simply discover joy in the moment.” She gave Twilight’s thigh a little squeeze. “You seem to be able to do that in the bedroom…”

Twilight laughed softly. “Well, that's different,” she said. “Anyway… I'm sorry if I'm stressing you out. I'm just not used to being in the dark about something for so long. I wish I had the time to learn medical magic, so I could keep track of things myself…”

“Oh, heavens!” said Luna. “No, darling. If you knew how, you'd be giving us checkups twice daily, fretting over every stage of growth, charting the development of each foal in meticulous detail. The stress would turn your coat whiter than Tia’s.”

“You're not wrong,” sighed Twilight.

“I know it will not come easy to you, dear,” said Luna, resting her head on Twilight’s shoulder, “but when you cannot control something, and cannot even know it… let yourself be freed by that powerlessness. As a princess - and as a parent, I should think - you must focus on what you can control.”

“I'll try and take that to heart, Luna,” said Twilight. “Thank you.”

The carriage came to a stop outside the front entrance of Canterlot Hospital. Twilight straightened in her seat and then abruptly vanished, reappearing outside the vehicle. “Let me help you down, ladies,” she said, opening the cart door and offering a hand.

“We’re not yet so pregnant that we can't dismount a carriage,” laughed Luna, “but I won't turn down an opportunity to be waited upon by my beautiful wife.” She took Twilight’s hand and let herself be guided down to the cobblestones, and Celestia followed after her.

“So is it always a one-on-one thing?” Twilight asked the handsome young nurse who'd guided the royal sisters to their respective examination rooms. “I can't sit in on them?”

“It is policy, yes,” said the nurse. “Since you're a princess, I guess you could order me to let you in.”

Twilight sighed and took a seat, plopping herself down on a bench between the two examination rooms. “No, that would be a petty abuse of power,” she said. “I just talked with my wives about not letting my worries control me, and this seems like a good opportunity to just… relax, and let things unfold at their own pace.”

“That's a very healthy attitude,” said the nurse. “Believe me, I've seen…” he turned his head, reacting to something in Celestia's examination room. “Oh, pardon me, your highness, just sit tight…”

The nurse entered Celestia's room, shutting the door behind him, and Twilight heard a pair of muffled voices, barely above a whisper. She was tempted to put her ear up to the door - or attempt some more magical means of eavesdropping - but she throttled that urge and sought a way to keep her mind distracted.

Any unicorn who worked in academia knew the basic book-summoning spell, and Twilight had adapted it to instantly deliver the last ten books she’d read. At the moment, all ten were books on pregnancy and parenting, thick volumes representing everything from the most ancient wisdom to the most daringly modern methods. A rectangle of violet light appeared beside Twilight, and the heavy stack of books fell from it and thudded onto the bench.

Twilight plucked a book from the middle of the stack and opened it in her lap. A book on “supportive fatherhood,” co-authored by a married stallion and mare. Twilight didn't think of herself as the “father” of her wives’ foals, but she was the only one in the relationship who wasn't getting pregnant, so… close enough?

Whether or not there was something to learn from the book, it was certainly enough to keep Twilight’s mind occupied. Before she could get too absorbed in it, though, she noticed a nurse striding purposefully out of Luna’sroom. The nurse disappeared around a corner and returned leading a doctor - no, two doctors - who avoided Twilight’s eyes as they entered Luna’s examination room.

Okay. Twilight could allow herself to be worried about that... or she could choose to be free of worry. To leave this problem - no, this situation - in the hands of medical professionals, and accept that she was not in control. Twilight drew in a long breath and turned her eyes back to her book, forcing herself not to see anything beyond its margins…

But she couldn't help but see two more pairs of legs striding past her - towards Celestia's room this time - and she lifted her eyes from the page. The activity was only accelerating now - doctors were huddling at both doorways, exchanging whispers, casting nervous glances at Twilight Sparkle. Sometimes one would enter or leave, pushing their way past the doctors who crowded the small rooms.

The effort of not worrying was steadily becoming unbearable. Twilight's shoulders were tense, her grip on her book getting uncomfortably tight - and tension was building in her horn as well, manifesting as a thick purple miasma.

Eventually, one of the doctors made the mistake of noticing Twilight Sparkle’s tension-wracked posture and darkly glowing horn. The doctor turned to discreetly look at her - and Twilight turned to look back, freezing the doctor in her gaze. Twilight’s expression was eerily empty, the tight grimace of a mare who was holding back a landslide of uncomfortable emotions - and that expression stayed frozen in place as she threw down her book and rose from her seat.

Twilight looked from side to side, swinging her gaze over the huddled doctors. What were they whispering about? What were they hiding from her? What could be so dire, so unprecedented, that it required so many doctors to come and consult?

Twilight’s mind raced. She'd spent the last few months studying medical literature, familiarizing herself with nearly every complication that a pregnant mare could experience. None of those complications would justify this much activity, even when the patient was a princess. Was this something totally unknown to ponykind? Some disastrous consequence of the fertility spells that Twilight told her wives to cast? Was this her fault?

Twilight was deep inside her own head - but her anxiety was powerful enough that it was manifesting all around her. The miasma around her horn spread downwards, enveloping her entire body in a shivering aura of unfocused magic. The doctors cowered, trembling and silent - until someone took the initiative and shoved a young doctor forward. The unlucky doctor stumbled forward, barely stopping himself before he smacked into Twilight, and hesitantly raised his head to meet Twilight’s eyes.

“Princess Twilight,” he said, his voice trembling like a windblown leaf, “it’s now okay for you to see your wives. We're just getting one of the bigger meeting rooms ready for the three of you and their doctors.”

This good news cut through Twilight’s internal storm, and she started to become aware of the scene she was making: the quivering doctor in front of her, the color drained from his face. The other doctors, huddling behind him, cowering from the princess’ royal ire. And the uncontrolled magic swirling around her body, raw power barely held in place by Twilight Sparkle’s aura. This was no way for Twilight to treat her subjects - especially those who were attending to her pregnant wives.

With a dispelling pulse from her horn, Twilight snuffed out the raw magic surrounding her. With a hot blush and an embarrassed laugh, she addressed the young doctor. “Sorry about that,” she said. “Lead on.”

Later that day, Celestia and Luna lay atop the plush, luxurious lounge chairs in their private study. But try as they might to relax, the sight of their wife pacing the floor made it impossible to set aside the worries of the day.

“Tia,” said Princess Luna, “I fear that our beloved Twilight has not entirely taken to heart our advice.”

“Yes, anxiety weighs heavy on her perfect shoulders,” sighed Celestia. “Although I confess that today’s revelation has me somewhat anxious as well.”

Twilight stopped pacing and turned to her wives. “Nine fetal heartbeats,” she said. “Nine each. We’re having eighteen foals!”

“This is not what we planned for,” agreed Luna. “And I cannot think how it happened! Your spellcraft was flawless as always, and unless the magic was somehow disrupted-” she paused, her brow furrowing and her mouth twisting into a snarl. “Nightmare! Daybreaker! Come out and explain yourselves to Twilight!”

Without any change in their relaxed posture, the princesses transformed into their alter egos. Their bodies swelled with muscle, limbs bulging powerfully as their dresses ripped into tatters. Celestia’s mane burst into a plume of self-sustaining flames, and Luna’s billowed into a flowing veil of starry night. Watching the brief transformation, Twilight was at first confused, then shocked, then furious, as she realized why Luna had called out the princess’ amazonian doppelgangers.

“What in the name of Harmony were you thinking?” demanded Twilight. “Do you have any idea how dangerous and prone to complications pregnancies this large are?”

A smile spread over Daybreaker’s face. She swung her legs over the edge of her chair, planted her feet on the ground, and stretched to her full glorious height. Undeterred by Twilight’s scowl, Daybreaker embraced her wife, squeezing Twilight tight against her soft bosom and firm chest. “Calm yourself, my love,” she said. “The dangers you speak of are for mortals, and we are the two most powerful immortals in this world. Our bodies do as we will, my dear; one foal or a hundred matters little to us.”

Held in Daybreaker’s warm and powerful embrace, it was difficult for Twilight to maintain her anger - but that anger was richly justified and she wasn’t ready to let go of it just yet. She pushed Daybreaker away, and the fiery titan released Twilight from her arms.

“You can’t know for certain that there are no risks,” said Twilight. “For all your power, you’re still ponies. And you’ve never been pregnant before! You’re recklessly putting yourselves at risk - you’re putting our family at risk!”

“If we relied on power alone,” said Nightmare Moon, rising casually from her seat, “you might have cause to worry. But we planned this carefully, Daybreaker and I. Your spells allowed every egg to be placed with forethought and precision... and although nine foals might seem ambitious, we did not give our bodies more than they could handle. The foals have all the room they need, and no spot is unduly stressed. There may be some mild discomfort as the foals grow, but we will all be safe.”

Twilight sighed, letting some of the anger fall from her face. “Well, knowing you had some kind of plan… a little forethought… that does make me feel better. But why do this at all?”

Nightmare Moon met Twilight’s exasperated face with a loving smile. “Why, to fulfill the desire of our lover’s heart,” she said. “I've been in your dreams, Twilight. I know that you wish to have children beyond counting.”

Twilight pinched the bridge of her nose. “Okay, one, entering my dreams without permission definitely crosses a line. Two, fantasy foals don't have real needs or wants. Real foals need constant care and attention. I can't even imagine how we'd raise eighteen at once, and I couldn't live with myself if we neglected even one of them.”

Daybreaker stepped forward, and Twilight allowed herself to be embraced again. “We could not agree more, Twilight,” said Daybreaker, “but remember - our foals will have the five greatest mothers in the world to care for them.”

Twilight, her face buried in Daybreaker's bosom, raised an eyebrow skeptically. “The four of you are sharing two bodies,” she said. “Bodies that need to sleep.”

Nightmare Moon put her hand on Twilight’s shoulder, gently pulling her away from Daybreaker. “Yes and no,” she said. “For beings such as ourselves, it is our minds - rather than our bodies - that require rest. Now that Daybreaker and I are no longer caged, we could easily swap with our counterparts when one needs to rest. The children will be cared for at all hours.”

Twilight shook her head. “Even with that, you're seriously underestimating how much work this many foals will be. I've read that-”

Nightmare Moon leaned down and silenced Twilight with a kiss. “What's done is done,” she said, once their lips separated. “Perhaps a show of good faith will reassure you that we are taking this task seriously. Since the size of this pregnancy is our responsibility, Daybreaker and I will shoulder the consequences. Whenever Celestia or Luna experience the slightest discomfort, they can swap to us and we shall suffer in their stead."

Daybreaker smirked, striking a confident pose that widened the tears in her tattered dress. "That shouldn't be too hard,” she scoffed. “Celestia has gone soft in this time of peace. What she considers discomfort will be trivial for me to handle."
