Rainbow Dash slammed the door closed behind her. Nopony followed her, she was pretty sure. Nopony saw her come in, but just to be sure she locked the door. Then she pulled the deadbolt. And maybe she should pressurize the seal, just in case. She backed away from the door, jittering in fear and confusion. She couldn’t even think straight. Her cunt didn’t feel like she’d just fucked half the population of Ponyville, but the images kept coming to her. Dash didn’t know what she was doing, or why she was doing it.
Nervously, Dash canvased her whole house, pulling all her windows tightly shut, and closing and locking all her doors. She didn’t want anypony to come in here. Not one pony. She was just too shaken to even see one pony at this point. She just wanted to be alone, so she could think a moment.
“I–I’ve gotta think,” Rainbow Dash said shakily, “I–I’ve gotta... oh Celestia,” and right about then Rainbow Dash realized she hadn’t eaten in like... days. It had been days, hadn’t it? She stumbled through the house like a drunk mare, not even bothering to right the chair she knocked over, getting into the kitchen feeling like her sleek, slim stomach was an empty hole boring its way inside her. She got a snack a... peanut butter and bread, but she was so hungry she just started eating the peanut butter straight out of the jar. Then the bread. And all that bread wasn’t enough! She went through a whole head of celery, the bits that fell out of her mouth tangling in the cloud floor as they slowly descended forgotten. She finished off her cabbage, and those anchovys she had in the freezer. Okay, so Rainbow Dash wasn’t the greatest of planners and she needed to go shopping. But she needed to eat now! And she needed to eat now!
“Fill up, you stupid thing!” she shouted at her own abdomen, which gurgled stubbornly, needing Dash to replenish three days worth of food in seconds. This wasn’t just hunger this was... wrong somehow. Why wasn’t her belly getting bigger? She cleaned the crackers and cookies out of the cabinet, and just spilled the rice because that stuff is hard to chew dry. No amount of hay, no amount of soy, no amount of anything would make her bigger. She couldn’t stand it! And the more she ate, the hornier she got! She had just fucked... fucked all those stallions, and mares, and she was still practically melting behind her belly button. With her last bottle of pickles cradled on her belly, Dash stuck a hoof there and started masturbating again. And as soon as she did...
Her hunger evaporated. “A–ahhh,” Dash exclaimed in surprised relief, rubbing herself to smooth out all the tension and worry, the cramped hunger inside her just fading away. Maybe she just... needed to spend more time on this. Yeah, she was done eating, and now she had to finish herself. Rainbow Dash just felt like everything was prepared. Almost in a daze she stumbled off toward her bedroom, tripping over a fallen lamp, but otherwise making it there okay. In her bedroom was her soft, inviting cloud bed, and in her bedroom was that amazing statue that could make her orgasm so good. Its light pulsed even as she walked in, her knees going weak as the light entered her receptive eyes and stayed there.
Dash didn’t even make it to the bed. She just had to rub herself, and she had to do it right now. She just splayed out flat on the floor and attacked her clitoris, the orgasm rising in her like a beast. And almost like clockwork, as soon as Dash’s sopping cunt started to ripple inside her, filling her mind with stars, that statue beside her bed pulsed with light again. The light filled her eyes, and Rainbow Dash moaned as the orgasm grew so much more intense, tossing her head like a madmare as her legs twitched and she clenched again and again on nothing. She needed a stallion bad, but she couldn’t get one because she couldn’t even move this orgasm was so good.
Then before her half seeing eyes, with a wet thump, the statue fell over on its side. All by itself. It didn’t even look like a statue anymore. It looked like a real dildo. And no, it... it looked like a stallion. Dash wanted it so bad. It turned towards her.
That both terrified and excited Rainbow Dash. She didn’t know what was happening to it, what was happening to her, but she did want it inside her, and it almost felt like an old lover, as it slid across the floor towards Dash’s awaiting cunt. It almost fell through the clouds, but its forward motion kept it buoyant, just like she needed.
“Ohhh yessss,” Dash slurred, rubbing her clit on the edge of another orgasm. It was coming to her. It was coming to her! Rainbow Dash spread her legs needily, expectantly, the strange disembodied phallus sliding closer and closer, and coming faster as its course steadied and it zeroed in on her vulva. She spread her vulva wide in both hooves. She had to, because she had to let it... let it... fuck her. She had to get it inside her. She felt it slide along her tail.
And then it was against her, and in her. Rainbow Dash cried out in ecstasy as her vagina erupted into convulsions again and this time she was forced wide inch by inch, by a truly massive phallus spreading her to her limits, until instead of contracting to slow its entry, all she could do was contract around it. It was like the best penis she ever felt. How was it moving like that?
It shoved roughly against Dash, making her emit a quiet creaky scream as it filled her so deeply and she couldn’t she couldn’t think. Then it started fucking her.
Dash’s breathing turned into regular huffs as the strange dildo statue pounded her pussy. And amazingly as she watched, every thrust seemed to make her belly plumper, and her body so immensely satisfied. She was swelling up right before her eyes, and all that hunger and horniness before was just beautifully answered by what was happening to her. Dash moaned and pushed on her belly with both forehooves, not because she wanted it to go down, but because squeezing it just felt so good. It only responded by redoubling its rate of expansion. It seemed like the more she squeezed herself, the more of her there was to squeeze. It distorted around her frantic hooves like she was some kind of water balloon.
Dash almost couldn’t hold her belly when she climaxed. She clutched her swelling abdomen hungrily, moaning one more time as her cunt rippled deep down in there, with the dildo statue shoving inside her and staying there. Dash cried out in quiet squeaks, writhing around it in there, feeling like it was permeating through her whole body. Her hooves couldn’t hold her belly anymore, only push it and be pushed back by it, as Dash was pushed away from her own bed by the swelling just above her groin. It wasn’t her stomach that was swelling, it was her womb! Dash was so pregnant she couldn’t stand it, and tears of joy leaked down her eyes as the orgasm plumped her up obscenely, and filled her with child.
She must have passed out then, because only later did she wake up with a stiff neck on her floor, saying vaguely, “Where...?” and when she opened her eyes, there was nothing in front of Rainbow Dash but a solid uniform blue. “Wha—” she said in shock, sitting up, or trying to sit up. She fell back at the truly unbelievably massive belly that was completely pinning her to the ground. Dash felt so weak, even her powerful wings couldn’t do more than rock herself in place. It was like that massive belly was sucking out her very vitality to sustain itself. Almost like...
“Oh no...” Rainbow Dash said in horror. “I’m pregnant!”
She tried to reach the dildo embedded in her vagina, but she couldn’t do more than flail her hooves around uselessly. Her tail lifted. It... couldn’t feel things very well, but all Dash could find with it were a soft and very broad, thick set of vulval lips, not stretched open around a dildo at all. How deep had that thing gone inside her? Dash couldn’t tell. The only thing she could tell is that she could barely see, couldn’t walk, stand or even roll, and she was all alone in her house now.
“H...help?” Dash called out. “H-help...” but her call turned to a whimper as she realized whoever came to help would see her like this, and know what she did to herself. Rainbow didn’t know the statue could get overloaded. That must have been what happened. She was just a stupid mare who thought she could fuck all the stallions without consequences, and her birth control backfired on her, so now she had like, ten foals at once growing in there.
“But I didn’t want to...” she whimpered, and there was nopony to answer her. Nopony other than herself. The stupid mare who did this to herself. Rainbow Dash just completely broke down and cried.
If only that were the worst of it. But it almost seemed like Dash’s womb was getting even bigger! She didn’t want to give birth. Maybe it didn’t usually hurt, but this was ridiculous! How was Dash going to do it? She had to like, get a doctor or something. But she couldn’t even move!
Her days were tormented by fears about the birth, and about herself. She cried about her doomed stunt career. She’d be lucky if she ever flew again after a birth like this. She cried about the unfairness of it all, how all she did was try to have normal lesbian sex with Scootaloo, and it just got out of control from there. She should never have, she didn’t want to, these were her thoughts on the surface, but the reality was she did, and she had wanted to. She even wanted this ridiculously big pregnant belly. It’d felt so good while it was forming, she just had to make it bigger and bigger. Somehow, Dash blamed herself for that too.
She cried because she couldn’t reach her pillow, and try as she might she couldn’t fluff up this hard, flat floor material. She cried because her warm, soft bed was right there, right against her swollen abdomen, and Dash couldn’t sleep in it, because she couldn’t move. Just stuck here on this stupid floor, no matter how dismal, hard, or cold it got.
But mostly... she cried from loneliness. She hid, and snuck, and locked herself away, and that filled Dash with a dreadful loneliness. An idleness that drove her straight mad, nothing to do but lie there all day, waiting for the sun to go down, and rise up again. Nopony knew she was in here, and nopony could know, because then they would see. That’s why the loneliness hurt so much, because Dash had to keep hurting herself, because of the mistakes she made before. Her friend, her—
Her friend Twilight came calling, literally! “Rainbow Dash!” Twilight’s faint voice echoed from far below. Rainbow could have—should have screamed for help as loud as she could, but she was so terrified she could barely squeak. Just the thought of somepony seeing her like this, of Twilight finding out and doing something to her massive belly, Dash couldn’t stand the idea of that happening! She hated this thing that happened to her, but she felt a powerful compulsion to protect it. Her child within her?
Dash didn’t like feeling like a mother. It wasn’t fun having your own body forcing you to protect something that you didn’t even ask for. It wasn’t fun wishing you could choose between your baby and your friends, and being unable to choose your friends no matter what. That wasn’t what loyalty was about. It wasn’t about betraying everypony just for the sake of one pony’s inconvenience. It just felt wrong. But it felt right, too! Because she was supposed to love her foal! Or... foals from the look of it. Lots of foals. Lots and lots of foals.
Rainbow just lay there quietly, listening in terror until her friend stopped calling after her. She was safe up here, right? Twilight couldn’t come up here. But she could tell Fluttershy or another pegasus even, and then...then.... Once Twilight had left, Rainbow started crying again, about how she had to let down all her friends, about the birth she was clearly going to have to suffer through, and suffer through it all alone by herself. And it was all her fault.
When Twilight finally went and broke into her house, Dash was freaking out with panic. She couldn’t betray her foal, but there was no way she could avoid Twilight, or escape discovery, if she couldn’t even move. When Twilight made her way to Dash’s bedroom door, she tried to beg Twilight for help, but that need, that fear that something might happen to her child just had Dash screaming senselessly at Twilight to leave, and that everything was fine. Well, everything wasn’t fine! This was about the opposite of fine anything could be! But she couldn’t come in or she’d know!
Twilight Sparkle was just about the best friend Rainbow Dash could ever possibly have, because she broke into Rainbow’s house, disrespected Rainbow Dash’s wishes, and violated her privacy, charging into her bedroom in order to berate her and talk down to her, and that was exactly what Rainbow Dash needed somepony to do. It was her only hope; Dash was powerless if nopony would force their way in to save her. She felt like her... her instincts were traps in a big nasty dungeon temple, and some brave pony had to disarm them and get past them and find her, right there in the middle of them, slowly being buried alive.
Twilight Sparkle was the best friend Rainbow Dash could possibly have, because somehow she convinced Derpy of all ponies to give her a ride, neatly solving the problem of the stability of cloud material under a unicorn’s hoof. She was resourceful, insistent, and brilliant. But... as good a friend as she was, Twilight Sparkle just broke in and stared, not like she was Rainbow’s friend, but like Rainbow was a freakshow exhibit. Come see the amazing superpregnant mare, making stupider choices than any mare in history.
“What in the name of Celestia...” Twilight murmured, and Twilight never invoked the princess’s name.
“I...I know I bucked up,” Rainbow said in tearful resentment. “Go ahead and laugh.”
“What?” Twilight said in a daze.
“I already know how stupid I am,” Dash said to her tremulously.
“...what?” Twilight said a little more comprehendingly.
“I did this to myself, Twilight,” Dash said angrily, wishing so bad that she could get up. “I made myself like, superpregnant, by b-bucking right up under a ton of stallions!”
Twilight blinked, from where she awkwardly perched atop her very uneasy looking, derp-eyed mount.
“...no, you didn’t,” Twilight said, in a flat tone of correction.
“Yes I did,” Rainbow snapped at her. “You saw! Or heard. Or like... Derpy told you about all those stallions I wasn’t... safe with. I didn’t mean to! But I just couldn’t stop, ‘cause I’m a stupid mare who can’t—”
“Rainbow Dash,” Twilight said in a smouldering anger, “You did not do this to yourself!”
Rainbow found herself nervous before Twilight’s odd reaction, and her fierce temper. Rainbow Dash looked aside, muttering sullenly, “I don’t see any other superpregnant mares in here.”
“There—” Twilight facehooved, clearly exasperated with the stupid superpregnant mare who was so stupid, saying, “There is no such thing as... as superpregnancy. You think you can get like... like this just because you fucking bucked every stallion you could see?”
Wait, what? Rainbow gave her a long calculating blink. “...yes?” she asked uncertainly.
Twilight appeared to be counting with her eyes closed. She opened them and sighed saying, “Rainbow Dash, no matter how many stallions ejaculate into you, you only have one egg at a time. Very rarely two, but how many stallions doesn’t matter. One stallion can still give you twins, and a hundred can still give you only one. The only thing that matters is how many eggs your ovary has released.”
“Well—um—I did lots of mares, too!” Dash retorted uncertainly. “So that like, made me extra ovary...y.”
“Dash...” Twilight said almost sadly. “You need to visit the library more often. The presence of other mares can do nothing, other than prevent ovulation in some cases. That means zero children, not... this.”
“Well, fine!” Dash said angrily, trying and failing to cross her hooves. “What happened, then?”
“You’re asking me?” Twilight uttered in incredulity. “Why don’t you tell me what happened!”
“I b-bucked under a lot of stallions,” Rainbow Dash said hesitantly.
“Besides that,” Twilight asserted.
“...I’m really good at licking mares?”
“...no, besides that.”
“I... um... got an abortion?”
“Yes!” Twilight said in triumph, “Yes, tell me more about that. How did you get an abortion?”
“The normal way, I guess?” Dash said uncertainly. “I went to this store for adult stuff, and they had an ad for pregnancy services, so they gave me the statue and uh... I broke it, by fucking too many stallions.”
“Okay, let’s please stop focusing on the buckfuckery,” Twilight sighed weiarily, “You said they gave you a statue?”
“Y-yeah, that is how you do it, right?” Dash asked. Twilight just stared at her, while Derpy... not stared at her.
“They gave me a... statue,” Rainbow Dash continued uneasily. “It like, looked like a penis. I didn’t really think it was one. You just put it by your bed, and the next day your pregnancy worries are over. You... never heard of anything like that?”
“...no, no I haven’t,” Twilight said in a very suspicious tone.
“It made this light, that like, made my estrus really crazy,” Rainbow specified hopefully. “Is that how abortion works?”
“You know, if you’d just come to the library—” Twilight said in frustration, then lifted her head saying, “Wait, what kind of light?”
“Uh, I dunno like an enchantment or something,” Rainbow said. “It glowed in these cool patterns all over the stone. I thought it was like an alarm clock, and I was trying to shut it off, but then I just couldn’t stop masturbating. Uhm...” she looked down at her grotesquely massive belly. “Yeah, masturbating,” she said with a defeated sigh.
Twilight sat there quietly, then said, “Do you have any paper in your room?”
“Yeah, uh, should be on the bedtable?” Dash said, craning to try and see. “Can’t really see up the—” it floated over her head wrapped in magenta sparkles. “Oh, you got it.”
“And a quill?” Twilight said hopefully. She blinked then, and reached with her magic, levitating one of the feathers Dash had forgotten to clean up. “That is to say,” Twilight corrected herself, “An inkwell?”
“...first drawer,” Dash mumbled, hoping Twilight wouldn’t also want to look at her private diary in there. She didn’t. Twilight hovered out the inkwell, and dipped the tip of Rainbow Dash’s discarded pinion into it, then made a few quick strokes on the paper.
“These um... ‘cool patterns,’” Twilight asked. “They didn’t happen to include anything that looked like this, did they?”
“Uh, yeah I think so. That was the main symbol, like, near the base I think?” Dash said. “I really didn’t have much time to look at it, because I had to... you know.”
“Where is this statue?” Twilight asked, suddenly nervous. “It isn’t still by your bedtable, is it?”
Oh Celestia.
“N-no, it’s not,” Rainbow mumbled, blushing deeply.
“Where is it, then?” Twilight asked. “Another room?”
“You could say that,” Dash admitted cagily.
“Which room?” Twilight said, lighting up her horn. “It’s really important that I get a good look at it, so I can be sure that... well what I hope isn’t the case, is the case.”
Dash really couldn’t think of any poetic way to say this. “You know where a stallion and a mare love each other very much?” she asked suggestively.
“Rainbow Dash, this is not the time for jokes,” Twilight huffed in exasperation.
“It’s up there!” Dash blurted out.
“Up... there?” Twilight pointed a hoof at the ceiling.
“No, up... me,” Dash said with a heavy blush. “As in, up the place where a stallion and a mare love each other very much.”
Twilight stared, then exclaimed, “You shoved it up your vagina?!”
“No!” Dash protested angrily. “It was a big stone statue! I knew it wasn’t a dildo. Even the instructions said so!”
“Which instructions?” Twilight asked eagerly.
“Oh uh... they’re on the back of that paper you were drawing on,” Rainbow said uncertainly.
Twilight flipped the paper over, and scanned the instructions with an unsatisfied look. “So, it’s not up your vagina?” she asked, looking around the paper at Dash.
“No, it... it is,” Dash admitted in a subdued tone.
“But, you didn’t put it there?” Twilight queried raising an eyebrow. “Somepony else did it?”
“It... it did it all by itself!” Rainbow said pleadingly. “I just... it just fell off the table, and I thought it just fell, but then it started moving along the floor. I was lying there... here, and it just went right for me. I just spread my legs, and it just... dove in there. It wasn’t stone Twilight, it was a real penis somehow. I-it sounds weird now. I should have been freaked out by it, but I just loved it. I don’t... I don’t get it but I just... I just had to get it inside me. It felt so good Twilight?” Dash was crying again, saying, “I just had to, I couldn’t think about anything else. I just... I let it in me, and then this happened!
“Maybe if I didn’t let it inside it couldn’t have broken, and made me superpregnant,” Rainbow sobbed guiltily, “I just couldn’t stop spreading my legs to let it just jam in there, and then I just loved getting bigger so much and... and I’m scared, Twilight.”
“You should be,” Twilight murmured.
“What?” squeaked a terrified Rainbow Dash.
“Nothing,” Twilight said unconvincingly, “Listen, look, I need to uh, I have to research... something. At the library. I need to uh, just... just hold tight, okay?"
"I need help, Twilight!” Dash shouted angrily, “Not books!”
“I have to find out what you stumbled across, Rainbow Dash. There might be terrible consequences if I interfere at this point!”
“There already have been terrible consequences!” Rainbow protested, trying to gesture at her immense abdomen.
“You’re still yourself,” Twilight retorted, “You seem to be in stable condition. You aren’t in pain, actively mutating, giving birth, bleeding out of your orifices—”
“Giving birth?!” Dash exclaimed in terror, “I’d be torn apart! Wait, what was that about bleeding from—”
“The point is I need to research, and research hard, before something even worse happens,” Twilight growled out excitedly. “So you just hold tight and don’t go anywhere.”
“I don’t think I’m going anywhere like this,” Rainbow Dash said in an acrid tone.
“Okay,” Twilight pronounced, “I’ll be back as soon as I can, Rainbow Dash.”
“Wait!” Dash protested desperately, “You can’t just—don’t leave me!”
Twilight regarded her silently, and Dash just tried not to cry even more as she forced herself to say,
“I don’t wanna be alone.”
“She can be my official eyeball platform!” Derpy suggested from beneath where Rainbow’s friend perched precariously.
“...no,” Dash said warily, at Twilight’s thoughtful look.
“Derpy can keep you company,” Twilight said pleasantly. “And if anything bad happens, she can come straight to the library and tell me.”
“No,” Dash repeated, as if she hadn’t heard the first time.
“Well, see you Rainbow,” Twilight chirped curtly, “Can’t delay any longer, let’s go Derpy!”
“Wait, I changed my mind!” Dash shouted after her, ignored as Derpy trotted out of Rainbow Dash’s room with Twilight, swooping down the stairs, out of her house.
Some time later, Derpy returned alone, with a smile beneath her misaligned eyes. “Healthy hamsters, Colorfast, the world is mine,” she told Rainbow Dash helpfully.
“Ugh, Derpy,” Dash moaned exasperatedly. “I’m literally a fat hamster now, and you shouldn’t beat the pots with sticks.”
