Twilight Sparkle, the Mother of Equestria
Twilight should have been used to urgent summons from Canterlot by this point, but somehow she had never quite learned how to calm herself down when they came. Instead she was scrambling to get to Canterlot as soon as Celestia's letter came. It would have helped at least a little if Celestia ever bothered to explain what was going on in her letters, but Twilight, now that she was a teacher, recognized that everypony had something they needed to work on improving. Unfortunately, she couldn't give Celestia homework, so all she could do was show up to hear what she had to say directly.
She was used to the scene that greeted her as she entered the throne room. Celestia and Luna sat next to each other, imposing, regal. They dismissed the guards as Twilight entered; it was a sensitive matter, evidently.
"Twilight, thank you for coming," Celestia said. "I—we—have a favor to ask you. The biggest request I have ever made of you."
Twilight had to keep herself from bowing out of instinct. She reminded herself that she was their peer now. Their peer and their friend, they couldn't order her to help them now, but they didn't need to. "If there is anything you need I'm happy to help."
Celestia and Luna glanced at each other. "This... is not the best place to discuss this," said Luna, "Let us go to our private chambers." Twilight nodded. Luna's horn flashed and teleported them all away. When the spots cleared from her vision she was in Celestia's bedroom.
"What's the matter?" Twilight said.
Both of the other princesses looked, not quite uncomfortable, but uneasy, perturbed. Whatever they had to say, Twilight could see that it was awkward.
Luna spoke first. "It is not urgent, as such. But..."
Celestia picked up where her sister trailed off, "You see, the birth rate in Equestria as been declining the last few years. Not much, but enough to make a pattern. The effects won't become obvious for many years, but I do worry about the population dropping too much."
"I see," Twilight said. She had seen the data, of course, but nothing about it had seemed at all out of place, let alone concerning. It seemed her mentor felt otherwise. "And where do I come in?" She supposed she could run some kind of advertising campaign, as the newest princess, she was the one ponies got the most excited about.
Both sisters smiled at her. Celestia remained the one leading the conversation. "There's no dancing around it, so I'll be frank. We would like you—if and only if you are willing—to make up the difference. To be the mother of the foals Equestria needs to keep growing."
Twilight didn't understand. "What do you mean?"
"I mean what I said. I am asking you to bear foals. I would not ask you, but Luna and I are old, all the children we may have we have had."
It was mother those foals in the literal sense, then. Twilight wasn't ready for that answer. Any other way interpreting things she could have had an answer for, but that one...
There was only one thing she could say in the moment. "I can't. I'm not ready for—that."
Celestia came close and put a hoof on her shoulder, Luna stayed back but looked at her compassionately. "Whatever help you need, I will make sure you have. If you do not feel you can, or even merely don't want to, raise your children, then I will provide for them. And of course, you do not have to do anything until you wish to, if you do not feel ready."
Twilight had been expecting a monster or something. Motherhood was just about last on the list of things she had been ready for. Was she ready to be a mother, in any circumstance? She had been wondering what it was like ever since Cadance had Flurry. She loved being an aunt, certainly. Why not have a foal of her own? Or foals, from the sound of it. But there were still questions to clear up. "W-who would be the father?" she asked. That was the critical one. Not having met the right stallion yet wasn't the only reason she was single, but it was a big one.
Celestia and Luna both grinned at that. "Me," Celestia said. "I as well," Luna added.
Unexpected answers seemed to be the general them of the meeting, but that, that was unexpected. Celestia preempted her questions by sitting in front of her and spreading her hind legs wide, exposing parts of her that were normally hidden. Twilight could see her teats, more than that, she could see Celestia's sheath and testicles, the genitals of a stallion.
Twilight felt many emotions in that moment. She had had a crush on Celestia for a long time. The idea of making foals with her, honestly, was an interesting one. She didn't even mind the stallion bits. She had never felt the need to tell anypony that she was bisexual, but those were the facts. And Luna? Luna was a friend, but a partner? Well, again, she was a friend, and more, she was plenty attractive herself. Twilight did not need to think long to realize that whether she was willing or not wasn't the most important question. What was something she had never dared to ask before. "If I do this... Would you just use me for foals, or could we have something more?" She looked Celestia in the eye, then Luna, and kept switching between them. If she was going to come out with her royal crush, why not consider polyamory while she was at it?
"I, for one, would gladly be thy lover," Luna said. She stood up, walked over, and gave Twilight a small kiss.
It was all she could do to remain standing. How to convert a friendship into love and romance had been one of the most elusive questions Twilight had encountered, and now that conversion was happening right in front of her.
Then Celestia stepped forward. She hugged Twilight and Luna both with her wings. "I would be honored to join you and my sister in an even closer relationship, Twilight," she said.
If not for the wing hug, Twilight would have collapsed, swooning. She had fantasized about words like those many, many times, never daring to imagine she would actually hear them. The sound of Celestia's voice saying them was pure bliss.
But Twilight was still a goal-oriented pony. She couldn't let herself forget what she had been brought for. "So, uh, how is this going to work? I mean, which of you is..." for a long moment Twilight felt like Fluttershy, and then she forced herself to finish to question, "which of you is going first."
Celestia ran her hoof through Twilight's mane. "You are not familiar with the magic involved in this. Both Luna and I will, ah, 'take' you at the same time."
Twilight's eyes, despite her intentions, went first to Celestia's crotch, then Luna's. "I'm not sure you both will fit..."
Luna lifted her chin. "Worry not, we are masters of sex magic! Thou shalt come to no harm in our care. Art thou ready?"
Twilight nodded. She didn't trust herself to speak. It was all too exciting, too hard to believe any part of it.
She took deep breaths. She stood still and tried to calm her rapidly beating heart as best she could as Celestia and Luna walked in circles around her. They cast spells on her and themselves. The magic made her tingle from horn to tail, but especially in her nethers.
"We're all ready if you are," Celestia whispered in her ear. Luna nibbled her other ear.
Twilight willed herself to be bold, and turned and kissed Celestia by way of an answer. The elder alicorn's lips were soft and thrilling.
Her former teacher, and future marefriend, lifted her magically into the air and put her gently down on the bed that dominated the room. Twilight was still mentally preparing herself for what was to come. But she knew she would not truly be able to acclimate to the idea of it until events were properly in motion. With two partners, she did not know how they wanted to position themselves, but she knew how to show them she was ready. She raised her hindquarters in the air and flicked her tail aside. For the first time in her life she presented her marehood to another pony. Just that little motion, that idea that she was completely exposed to somepony else, and specifically to the princesses, sent chills down her spines.
Luna, then Celestia climbed onto the bed. "Thank you, Twilight, truly," Celestia said.
"Thou art beautiful," Luna said. She punctuated her statement by kissing Twilight's vulva.
She gasped at the sensation. She was tempted to look back, but she held steady, and went only by what her nerves told her was happening.
She floated into the air and turned sideways, and floated down to the bed on her left side. A blue shimmer at the edges of her vision told her who was responsible for the motion. All was still then, except for muttering and occasional other noises from behind her.
Then a poke. She was a virgin, even so, she had no doubt what it was she felt brushing her nethers. Luna crawled into position behind her back, and the poke became—ahh—it pushed inside her. Princess Luna's cock entered her. It slid in, gentle and thick, filling, filling, filling her. It was warm, it throbbed, it was alive. And Luna's hooves held her from behind. And Luna loved her. There was no comparison at all between this and using her magic or a dildo to get off. She moaned, arching her neck, trying to look back to get a look at the Princess of the Night.
Then Celestia started scooting around. The Sun wriggled into place in front of her and she felt another poke. But that couldn't be right. They had said they would both enjoy her, but surely that couldn't be right. She was an alicorn, but she was still just a pony. Even so, Celestia pushed forward. Her thrust was slow and unstoppable. She looked into Twilight's eyes the whole time, watching for the slightest distress.
Luna's penis alone had stretched her: a size queen she was not, so most of her toys weren't as thick. But the enchantments that had been cast on her now showed their effect. Celestia stretched her impossibly, and yet the titanic pressure never crossed into pain. Her tongue lolled out. Twilight was too busy trying to calm herself, to quell the instinctual panic that the unnatural sensations produced to notice.
Despite all laws of biology and anatomy, Celestia fit. Her shaft sank into Twilight alongside Luna's. It slid in, vein by vein, ridge by ridge, until both cocks were in deep, just short of hitting Twilight's cervix.
Twilight had never been with another pony before. To be with two at once for her first time was overwhelming. But she was in good hooves. Neither Luna nor Celestia moved for long moments until she became a little used to the sensation of having them both in her, as well as the knowledge of that fact. They had already loved Twilight, her request for romance was only one more way to do so. To hurt Twilight even by accident was unthinkable.
Twilight's breathing and hammering heart didn't slow, but they became less desperate, less reminiscent of an animal caught in a trap, more like the goal, a mare in the arms of her lovers. Twilight was hugged from before and behind. That intimate, lovers' embrace was almost as thrilling as the penetration. Yes, she felt that at any moment she would split and be torn in two, but these ponies, they could tear her. She would happily give herself up for them.
Then they began to move. They began to fuck her. Even through the distinct slickness of a lubrication spell, Twilight had felt her cunt getting wetter by the second from the moment she got on the bed. It was nothing less than a mess that formed as Luna, then Celestia began to piston in and out of her. The wetness inside her quickly spread down to her thighs. She imagined her partners' pussies in a similar state, and the juices of three mares all mingling as they dripped onto the sheets. Not to mention the lather their exertions worked up.
Twilight wasn't sure what to look at. She wasn't sure she wasn't dreaming. Her head flopped this way and that. Finally Celestia caught her with a kiss. "Thank you," she whispered. 'Thank you,' her deep purple eyes said, as Twilight looked into them. She had dreamed about situations like this since she had hit puberty. To feel Celestia embracing her and fucking her, to see the feelings her body was giving Celestia flicker across her face was bliss.
Her relationship with Luna was much younger, of course. But the letters Luna had written to her showed a mare with a beautiful mind, and she was glad to be her friend. She was ecstatic to consummate that friendship.
Luna filling her from the back meant that Celestia's penis rubbed firmly against her clit and g-spot with every stroke. Between the physical sensations and the love she felt for both of them, her orgasm built quickly. She came wetly, crying our and curling up between the two other princesses. She couldn't see the aftermath of her first orgasm, but she had always been a squirter, and she could feel the wetness. Her muscles tried to clench, but there was too much cock in her, and she only felt a throbbing deep inside.
It was clear that this wasn't Celestia or Luna's first time. They kept churning her at just the same rate. They kept up the avalanche of sensations. Soon her back arched as she came again. She had known that the princess must be a wonderful lover, but that had not prepared her for the reality of it. She could have lay in that bed with them forever.
She came a third time before she noticed any sign of Celestia's stamina reaching its limit. As she whimpered from the wonderful glow her clit was giving off, she saw the Princess biting her lip and screwing her eyes shut.
"I-I'm read-y," she gasped huskily. "I'm ready for your foals."
Celestia didn't say anything, but she tilted her head forward. Twilight heard the princesses' horns clack together, and felt the buzz of magic flowing between them. Their rhythm shifted, they fucked her in perfect synchronization. Both sisters sped up suddenly, and drove as deep as they could.
It was Celestia and Luna's turn to cum, and they did so at the same time. Twilight sensed some of the other spells that had been cast over her activate as they flooded her with hot sperm. Both were deep inside her, both pumped their massive loads directly into Twilight's womb. Magic dulled the protests as her cervix as the flood rushed passed it. She felt herself swelling, her belly bloating as the spunk rushed into her and was kept from splashing back out like it normally would have.
She could not feel it directly, but she could sense that what happened next was important. Her womb was quickly filled up with semen, and it was then that having two ponies in her became important. With the enchantments they had cast, Celestia and Luna's seed did not mix. Each alicorn's cum rushed up one of Twilight's fallopian tubes. Both her ovaries were directly washed in the most potent sperm in Equestria. Every egg was fertilized simultaneously, supernatural power overcoming the limits of ordinary biology.
Twilight Sparkle was pregnant even before they pulled out. She ached, missing them as they extracted themselves from her depths. But although the sex was over their love still remained. Twilight was still being cuddled between them. She hugged Celestia, because she was in front of her. She would have liked to hug Luna too.
She didn't get her wish; her new marefriends pulled away from her. Celestia rolled off the bed and stood. Luna presumably did the same, and walked around to stand next to Celestia.
"How was it?" Luna said.
Twilight couldn't speak, she was too busy taking in everything she was feeling and had felt. She made a face that she hoped said 'wonderful.'
"I'm glad to see that you enjoyed it," Celestia said. "But, as much as I enjoyed it too, and look forward to enjoying your company again, remember that it is also work. Now comes the hard part. You are not just pregnant, you are very pregnant. Hundreds of foals are now developing in you. We will need to move quickly for you and them to survive."
Twilight couldn't feel anything yet, only the afterglow of the sex, but she believed them. There had been a lot of spells involved, she was heavily enchanted. And the semen steadily leaking out of her spoke for itself. "Are you going to call a doctor?" she asked.
Celestia shook her head as she got into position at the side of the bed. "No, there are no doctors who know how to deal with this. Only Luna and I."
Twilight's body tingled as they began to weave yet more spells over her. She couldn't help but be nervous. She had never known Celestia to have any talents in medicine. And it was hard to really believe all the things she was saying. Surely it was impossible, even with magic. But if there was one pony she trusted, it was Celestia.
Somepony's magic rolled her onto her back. She felt a tightness in her abdomen. It was really happening. The spellcasting around her continue to intensify. As she stared down her body she could see her belly begin to swell. She felt the unstoppable pressure driving it, but no pain. Her breaths became shallow pants. Something like sickness washed over her, leaving no doubts about the unnatural things that were happening in her body. She felt weak. All the while, her insides were churning.
It was hard to focus, but she could still think clearly enough to realize what was happening. The foals—her children—grow were growing rapidly, and just like normal foals they needed energy to do so. More energy than her body could provide. She turned to head to look pleadingly at Celestia, her vision growing dim. This is what she had been warned about. Despite the newness of the situation, as she died she was more worried for the foals than for herself.
Celestia's horn flared. New strength flowed into her and she gasped like she had been drowning.
"There, there, Twilight. You're okay. We're not going to let anything happen to you. Just relax. You might even enjoy it." Celestia's words were comforting, they gave Twilight almost as much strength as the magic pouring into her. Of course, she was with Celestia, and Luna too. Nothing bad could happen. They would never let any harm come to her or her children.
Her stomach continued to swell. It was only magic that held her flesh together as her womb bulged beyond all normal limits. Her torso was now a great purple bubble, comically dwarfing the rest of her body. She didn't care how it looked, didn't care how grotesque her appearance was. She only felt pride. She thought of her own mother, dreaming of all the possibilities for her little filly. And she multiplied that by a dozen, a hundred, more. She noted that the princesses must have been holding her belly up; it should have been crushing her. And she was still growing, they were still growing. She was barely a pony anymore, merely a living baby factory, a gigantic womb with some other parts attached.
Twilight's own body filled her vision now. How many ponies were in there? She should have been panicking. She should have been furious, or terrified, or disgusted at being turned into what she was. But she felt only calm. Celestia and Luna were her friends, they had warned her as best they could, but it was not possible to prepare for this. It didn't feel bad either.
And then the foals began to kick. They began to move. She knew it happened, she had felt Flurry Heart moving around inside Cadance. But to experience it first hoof was a different matter entirely. She couldn't believe how fast they were growing. But when she thought about it she realized that she didn't know how long she had been lying there. It felt like minutes, but her mind was hazy, it could have been full months for all she knew or cared.
All she knew was that the movement she felt was the life she had created, so many ponies whose destinies would spring from hers. This was the way to be a princess she realized. She had been teaching about friendship, but like this she could make it.
Her pregnancy progressed further. True to their word, the princesses did not allow any more complications, even as a village's worth of foals teemed inside her. She would never have described the experience as comfortable, but it was sublime in its own way; she never doubted for a second that it was worth it.
Even so, when the contractions started, Twilight wondered if she was dying again. Her body tried to go through its natural motions, but her muscles were hopelessly useless to squeeze her immense bulk. There was no mistaking what was happening, but all she could feel were feeble twitches.
Finally she felt somepony's magic tingling and reaching up her vagina. Pressure slowly built there, her body was stretched in yet another way. It was a fullness even greater than taking both Celestia and Luna's cocks at the same time.
There was the distinct sensation of something sliding through and popping out of her. She gasped. Then it happened again. And again. And again. She heard shuffling and the sound of ponies far away on the other side of her stomach. Crying too.
One by one by one the foals came out of her in an endless stream. Soon she couldn't even tell if magic was still being used to hold her open. Her canal was constantly full with newborns.
Twilight lay there for hours. Getting back down to normal size took a long time. She had lost track of how many babies had been pulled out of her well before she noticed any decrease in her massive belly. A gnawing emptiness emerged as the day went on, there was nothing to fill the space inside her anymore.
At long last she felt a foal drop away from her without another one on its tail. It was over. She heard ponies all around her, but was too exhausted even to sit up. All she could do was stare at Celestia's ceiling.
Luna came into view, wearing a smile. "Thou wert magnificent. Rest now; thou hath surely earned it." Sleep magic washed over her.
She regretted waking up. Much of the anesthetizing magic that had been cast on her had worn off, and her body had a lot of complaints about how she had treated it.
That was quickly forgotten when she opened her eyes. She found herself in the middle of an impromptu maternity ward. All around the room, and even out into the halls as far as she could see were beds. Little ones. And every one of them held a foal, swaddled up tightly. And she was the mother of each and every one of them. She wanted to hold them all, but there were so many. She levitated the nearest one to herself and cradled it in her arms. It was a pink pegasus filly, and she was adorable. It was selfish, but she wasn't satisfied, she wanted even more foals. Luckily she had two big-dicked princesses to help her.
