Sweetie looked at Rarity trustingly, then turned and raised her tail. The stallion was a large blue one, and his penis was a darker shade than the rest of him. The goo dripped out of her winking cunt even as he mounted up, practically walking over her and surrounding her with his presence. Then with a shuddering thrust, his penis was inside her.
Sweetie looked under herself as he fucked her, at her unassuming little white belly, so incredibly filled from inside. He was pushing the other stallion’s slimy stuff right out of her with his magnificent shaft. It was squishy and slidey and gooey and stretchy. He was going to squirt that seed that Rarity said. Sweetie would fill up with it again. Oh, she wanted to be filled up so bad! She thought about a foal in her, and that just made the young little unicorn pant, and lift her head to look forward, and rock back against him lustfully. The thought of her belly getting bigger was just somehow so incredible. He was going to do it to her too. It really was going to happen!
She... she didn’t want to have a foal, did she?
Sweetie was so confused. She hadn’t wanted a foal or anything, but thinking about bearing one and being so heavy down there just made her tingles so much more powerful, more potentious. “Oh Rarity, I don’t want a foal,” she said, tossing her curls away from her eyes. “It makes me feel so good though! He’s putting a foal in me~”
“Oh, Sweetie dear,” Rarity said now sitting on her belly beside the fucked filly. “Go ahead and let yourself want it. You can always change your mind when you’ve calmed down. The heat is filling you with passion to make a foal, just as it is Noteworthy who is giving you one. So indulge it. Let yourself want a foal, become the mare who will be a mother!”
“I want a foal,” Sweetie said with a burning passion, rocking drunkenly as the pleasure swam through her head. “My belly’s...gonna be so big” she moaned. “My foal~ coming out of me out where he is. He’s so big, Rarity!” she was reduced to mewling whines at that point, her hungry bottom quivering around his inflated cock. She imagined his seed up in there, doing things to her, turning an egg inside her into a foal. Her foal. She felt him jam up against her, thrashing in there, pumping. “He’s doing it Rarity!” she moaned desperately, her clenches taking over her whole thoughts, “He’s making me a mommy!”
And then she was lost to the world again, the last thing she saw her sister’s face, before her sight filled with stars, and all she could do is cry out in joy at the incredible squeezing squelching she had to do, gripping his pumping rod as the seed poured out of her young cleft, sliding down her legs and soaking her fur in potent manly musk. Sweetie was the happiest mommy ever, as the stallion fertilized her again and again.
“My... my foal, Rarity,” Sweetie murmured deliriously, laying there after her latest experience so empty, yet so satisfied. “It’s in my belly,” she purred, imagining the quivering in her insides as if they were busily making a foal with that seed. “For you, Rarity...”
Sweetie slid her eyes open at Rarity’s whimper, to see the blue stallion, Noteworthy apparantly his name, now fucking Rarity heartily. Rarity was standing just like Sweetie Belle had, but he could really grip Rarity’s rear as he hammered into it. Her expression almost pained, but Sweetie knew how it really was just indescribably overwhelming.
“R-rarity,” Sweetie stuttered, stumbling to her hooves and walking over to her. She hugged her sister while the stallion fucked her the second time. Then Sweetie gasped as she was pulled by her own rear end into another stallion’s grasp. Oh her bottom was so empty and tingly! She let go of Rarity, and pushed away, saying apologetically to her sister, “S-sorry Rarity, I need it.” stepping back under him, onto his hungry penis.
Rarity just watched Sweetie separate from her with a hungry expression, the penis within her sister making Rarity look so beautifully aroused. Sweetie felt a penis push on her bottom, then felt a penis push inside and then she was the same as her sister. Sweetie started breathing hard along with Rarity, both of them staring at each other, both of them fucked deep. Sweetie knew why Rarity was this way, because she had a penis inside her. Sweetie knew Rarity could feel it so full and deep, sliding and sliding in her, because the same thing was happening to Sweetie Belle. They were both completely surrounded by horny stallions, and they both were squirming wetly around the thick penises pistoning inside them.
So Sweetie was fucked face-to-face with her sister, and her sister was fucked by a stallion whom Sweetie’s estrus had incensed. Sweetie’s bottom place was hungry for foals, and that was making him go into Rarity, and giving Rarity those incredible feelings. Sweetie couldn’t believe it was true, but it was. Noteworthy’s face was an open mouthed expression of bliss. Because of what he was doing to Rarity. Because of the foal he put inside Sweetie Belle. Because of Sweetie Belle.
The stallion ballooned up inside Sweetie, and her eyes grew liquid, feeling the resurging tingles that she now knew would lead to that incredible experience Rarity called orgasm. It wasn’t going to happen before the stallion filled her dripping with seed, but there was another stallion after that, and another, and even just one orgasm had been the most incredible feeling Sweetie had ever felt. She would be in a happy haze from it for days afterwards.
Sweetie felt satisfied and hungry at the same time, as she felt his ejaculations pulsing in her hidden little filly canal. She lifted a leg and grunted tensely, as it burbled out around his throbbing shaft and slimed up her bottom even more. But the best thing is she could feel it going inside. Somewhere deep in there, Sweetie was stretched wide, and hot spurts smacked up against her in there.
“For my foal, Rarity,” Sweetie said sensuously, as the stallion pulled out of her wetly, the filly swaying on the spot before her sister practically distressed with lust. Sweetie rubbed at herself needily, smearing her hoof with that hot musky stallion spunk. “Six stallions, all in me. Making your foal in my belly,” she said, needing to—to show her. Sweetie held her hoof out in front of Rarity and it dripped off of it. “See, it was in me. It’s it’s dripping out because I’m full of foal now, Rarity,”
“Sweetie—you—I—ahhh...k” was Rarity’s answer, and her lips pursed in joy as she lost sight of what was in front of her, Rarity’s diamond bottom jerking rhythmically against the stallion who rutted her.
Sweetie didn’t know that an orgasm looked so incredible! That’s what she looked like? Bent under her stallion like Rarity was, quivering, limp maned, sweaty and glorious? Sweetie nuzzled Rarity, and Rarity didn’t even seem to notice, and that was incredible, because Sweetie knew just how Rarity felt. She left her sister then, to swing her tail aside for another stallion. To make that stallion feel so good, to make herself feel so good, to make a foal, and to show Rarity the beauty of an orgasm that Sweetie Belle was desperate to embody.
The little filly was thoroughly swept up in the furor of a hot, sunny powerful estrus, and it would be some time before she even thought about slowing down. She pumped and gasped, and slipped, and fell, and stood and did it again. Penises were home inside her. Her every thought until that evening was all stallions, foals, penises, seed, orgasms... and Rarity.
Sweetie Belle looked up at Rarity relaxing on her sofa, ever elegant despite extenuating circumstances. Her sister didn’t protest as Sweetie climbed up and rested her forelegs against Rarity’s growing tummy. It was so weird that Rarity’s belly had actually started getting bigger. Sweetie had a hard time even believing it at first, that a pony could grow a whole foal inside her belly. Well, not exactly in her belly, but in a special belly just for foals. Every filly had one, even Sweetie Belle, though she wasn’t using hers right now. Rarity said her inside place was called a vagina, but Sweetie still liked to think of it as an inside place or a special place, and at the end of that special inside place was something called a womb.
Sweetie touched her own belly with a hoof. It was soft and plush, like it always was. But there was once an egg in there, and there was once a lot of penises in there, and inside Sweetie’s unassuming innocent looking hips, a foal had been created. There was a point when it was floating inside her, in that tiny little womb she had in there. Sweetie Belle’s womb had no foal in it now though, and that was why Rarity’s belly, why her womb was so huge now. What was inside Rarity’s tummy... it used to be inside Sweetie Belle’s. That could have happened to her, if she didn’t have a sister to help her, and a talented librarian.
It was a teeny little pocket inside you, Rarity had said, in which a foal can grow. That’s why stallions were sticking their penises into Sweetie Belle’s inside place so many months ago, to put their seed into her womb so that a foal would be there. Sweetie wasn’t exactly clear on how, but it turns out ponies are a lot like chickens, and she actually did make an egg on accident, but pony eggs are really tiny like the size of a speck of dust, and Sweetie couldn’t lay her egg, since you wouldn’t even be able to find it if you did. She had more of a respect for chickens now, because Sweetie hadn’t even tried to make an egg; it just sort of happened. So a big egg comes out of them every week, without them even wanting it, yet they accept what their body is doing with a quiet grace. And a lot of exasperated clucking sometimes, when it’s a really big one.
But as tiny as pony eggs are, pony foals sure aren’t tiny, and since you can’t lay your egg like a chicken, you have to keep it in your belly—your womb, until it’s ready to hatch. Sweetie Belle almost had to do that, when she went into heat and stallions fertilized her egg, but Rarity made a great sacrifice and took the egg on herself. She called it a surrogate mother, and that made Sweetie happy, because she knew Rarity wanted to be a mother, even if it was the surrogate kind. But it also meant Sweetie Belle was a mother too, a donor...mother or something. The foal inside Rarity was made out of Sweetie Belle’s egg, so it was kind of like a piece of her, a piece who was getting hooves, and a head, and a tail and a whole body. Sweetie felt kind of like she’d split in two, even though she didn’t grow a big belly like Rarity, and it was only ever the size of a tiny speck when it was inside her. The foal had started kicking recently, and when Sweetie felt the weak little hooves in there press against her own through Rarity, she liked to pretend that she was touching her own hooves, like Sweetie Belle was in there, making Rarity so beautiful and pregnant.
It was so nice for Rarity, is the reason Sweetie was so pleased for being involved in it. Rarity had to eat more, and weird stuff and lots more salty food to build the foal’s electro...somethings. But aside from that, it had done her nothing but good. The extra energy it took to feed the foal with her placenta (Sweetie imagined it like sucking on a milk laden teacloth) was really slimming out Rarity’s figure, in the places where it counted. She would never be a supermodel pony, but there was just something beautiful about her body emerging from those little saggy places that accumulate over a life of stress and ice cream. Rarity was so smooth now, which is why Sweetie was laying on her. Rarity felt smooth and pliable, and warmer than ever. She said it was the progresster...things improving her skin tone. Even though Rarity’s belly was swelling up like she was getting fat, it wasn’t fat at all, but her womb growing bigger with a foal in it, and the rest of her body had only improved as a consequence.
Really it made Sweetie feel a lot... better about having a foal herself. She might not have had as easy a time herself, since she was still growing, and having a growing foal as well as growing herself it would have been just impossible to eat enough to keep up with all that. And she had grown a lot since she was a little swell like this in her own mother’s belly, but Sweetie was still pretty tiny. She imagined her own belly swelling up as much as Rarity’s had, and not proportionally since a foal grows just as fast no matter how big the mother is. Whereas it hung like a cradle from Rarity’s hips, accentuating her form and slowing her activity from the extra weight, Sweetie would have looked more like a beach ball, and she might not even been able to walk.
But as bad as it might have been, Rarity enjoyed it so much that Sweetie couldn’t help but be a little less afraid of having a foal. Rarity didn’t complain about the swelling, and it didn’t hurt at all. If anything it made Rarity feel pleasure, and she spent a lot of time just stroking her own belly. When Sweetie was big enough, she hoped she could get another egg, or maybe even Rarity’s egg. Then she could have her belly swell out just enough, without hindering her too much, and she’d be able to care for Rarity’s foal just by eating pickles and allowing her body to carry it. Sweetie had been upset that just a little bit of seed from the stallions had put a foal inside her without her even knowing it, but given a little forewarning and experience Sweetie was starting to think maybe it wasn’t such a bad idea after all.
Plus that wasn’t just a little bit of seed. Her bottom tingled just remembering what a sopping sticky mess she was once she and Rarity had helped stallions with their penises until the sun had gone down. With the egg inside her now a gift for another instead of a burden, Sweetie Belle had found it easy, even exciting to try and fertilize her egg as much as possible. It felt absolutely amazing first off, and every time a stallion started squirting into her quivering body, it just felt like ...when you put the cake in the oven. Sweetie was making something inside her to give to Rarity, and even though she didn’t have a choice about making it anymore, when she put her mind to it, it felt just amazing that she could make something like that to give. The whole morning afterwards Sweetie just felt so very special; she kept touching her belly and wondering at the magical process happening in there, her little speck becoming a teeny tiny foal.
Though there had been a bit of a scare when they visited Rarity’s friend, and she was worried it had implanted. The new egg/seed foal is still a speck size apparantly, but it burrows its way right into your womb, where your placenta starts growing. It’s a lot harder to move then, and could make Sweetie really sick if her placenta gets taken out too early, plus there’s something about tissue rejection and... well Twilight was really scaring her, until Rarity said that it had only been one day. Less than a day really, since Sweetie Belle hadn’t started getting impregnated until the afternoon. Then Twilight relaxed, because it takes at least 3 or 4 days before the foal speck has developed enough to start implanting. So thanks to Rarity’s fast thinking, all Twilight had to do was teleport a speck, not a whole... placenta womb thing.
She also told Rarity to eat something that made her womb... better or something. Sweetie hadn’t considered that her heat might have affected more than just her egg. It was making an egg go into her womb, and Sweetie had always had a womb, but it was also thickening the walls of the womb, and readying her for being... implanted in. It was both frightening and impressive that Sweetie just woke up one day, and had been changed to produce an egg, but even her whole tummy had changed to be better for implantation. And her inside place had changed, getting wetter and stuff, and her... head had changed. She realized that last part after her heat was over, and she stopped being so... hungry in her bottom place. It still felt amazing, and she loved orgasms and boy seed, but when she was in heat it had been more of a visceral need, like she felt like something was wrong if she wasn’t pumped full of goop.
Plus her smell had changed too. When her heat had ended, she found that stallions were no longer nearly as rude as they had been the day she got raped and impregnated. When she went into heat, Sweetie had been giving off a smell that was just irresistable to stallions, all more of this complex system to ensure that she get as pregnant as possible. That meant they wouldn’t talk to her or even ask her, just push her down and stick their penis in. Not that Sweetie had minded that one bit. With her heat changing her head, it made her think that being rude was good, and that she was glad they didn’t waste time asking an obvious question and just started getting to it.
When she wasn’t making the smell it was... harder to fuck stallions, but a lot more satisfying. She and Big Macintosh had reach an... understanding of sorts. She wished she could be his special somepony, but the age gap was just too great, and without the heat clouding her judgement, Sweetie started seeing that Big Macintosh needed a pony he could actually hold onto while fucking. And Sweetie was starting to realize she had feelings not just for him, but for others too... her friends Apple Bloom and Scootaloo, and even some colts she hadn’t hung around with much before. Sweetie had in particular taken a shine to a colt in her class called Snips. He was really goofy, but going into heat so young had given Sweetie an advantage, and it made her feel really powerful when she could show him all the grownup things you can do. Plus he had the most adorable face when he ejaculated.
Scootaloo wasn’t really all that interested in mushy stuff like inside places, but Apple Bloom was really into it. She knew even more than Sweetie did though, since she grew up on a farm, her sister wasn’t a huge prankster, and her parents weren’t... oops, no actually Sweetie’s parents were at least alive. But Apple Bloom had told Sweetie about what she learned from Winona, and then went and started licking herself, and then Sweetie tried it, and then they ended up licking each other because it was way easier to reach.
Apple Bloom knew a lot, but she hadn’t orgasmed yet, so she was excited when Sweetie almost collapsed by an orgasm, because she thought maybe Sweetie could do that for her too. And without Apple Bloom’s lovely lips and tongue distracting her from her duty, Sweetie did much better. Apple Bloom just lay belly up and gently instructed Sweetie Belle in what felt good for her, and it wasn’t too long until Apple Bloom’s cries peaked and her hips started jerking in a way Sweetie knew well. Sweetie was surprised when she grabbed Apple Bloom’s kicking hind legs so she could lick the orgasming pony, that it was so much Apple Bloom even peed on her!
Sweetie was especially surprised by the fact that it wasn’t as gross as she thought it would be. Kind of acidic, but you just don’t want to get any in your eyes pretty much. In future um... licking sessions, Sweetie liked to tongue at Apple Bloom’s urethra right before she went over, just to tease her into losing control of her bowels when that happened. Seeing Apple Bloom’s flushed face of embarassment for peeing all over her was just so adorable to Sweetie Belle. She loved having her friend so vulnerable and open before her. You really can’t keep secrets from someone whose curls are dripping in your own urine, after all. It was almost as adorable as when Sweetie Belle introduced Apple Bloom to Snips.
Well, not introduced, since they knew each other vaguely. But Snips and Sweetie had a giggling conspiracy together, where he snuck into the clubhouse right when Apple Bloom and Sweetie were having a licking session. Apple Bloom couldn’t get all shy either, because Sweetie just kept licking her, until she was putty in Sweetie’s ... mouth. She even tried to apologize to Snips after her orgasm was done, but Sweetie would have none of it. She said Apple Bloom had to do something that was even better than an orgasm, and it was just impossible for Apple Bloom to be shy, since Sweetie showed Snips her at her most vulnerable moment. So Apple Bloom reluctantly stood up, and let Snips mount her, and let me tell you the pheremones of heat are nothing compared to what seeing two fillies licking each other does to a stallion.
Sweetie reassured Apple Bloom, after she started protesting Snips going inside her, saying that’s supposed to happen. Apple Bloom looked so scared though as she tried to put up with it, so Sweetie went forward cradling Apple Bloom’s head, and helping her relax. Sweetie was surprised when Apple Bloom lunged forward and suddenly kissed her, right on the lips! Then Apple Bloom just about screamed into the kiss, with her eyes squeezed shut and her whole body going tense. When Sweetie pulled back, enough to leave Apple Bloom a gaping panting sweaty mess, Snips said he felt something in there but it just gave way when he pushed against it. He apologized profusely, and Apple Bloom said she... said it didn’t hurt anymore, and she sort of... liked when it did. “Ah kinda needed that, an’ you actually feel real nice in there,” were her exact words.
He started feeling more than kinda nice when he started thrusting. Sweetie watched Apple Bloom’s feelings turn from curiosity, to a nervous fear at the power in her starting to awaken, to open mouthed, tongue laden lust. Another good thing about not being in heat is the stallions can go way longer. When you’re in heat they have to start squirting right away, since it’s all about getting pregnant. But when out of heat, suffice to say Apple Bloom was in for the ride of her life.
Sweetie had started wanting to lick her though, because Apple Bloom was just so... beautifully ecstatic about what was happening to her. It didn’t really make sense. She just looked at Apple Bloom being fucked and, thought, “I want to make her orgasm really bad.” And that gave Sweetie a deliciously naughty idea. Because once scooted under Apple Bloom’s stiff legs, Sweetie Belle had more than just Apple Bloom to lick. She had Apple Bloom, and Snips. And Sweetie had never licked a penis before, so it was really exciting.
What was even more exciting was watching it pistoning into her friend’s inside place. It really did just vanish in there. So what Sweetie did was she just lifted her nose up, and started laying her tongue on Snips’ penis, right by the balls hanging from his groin that had the seeds inside them to make a foal in your belly. It was strangely familiar, the feel of Snips’ turgid length as he slid along her tongue, frantic to thrust into Apple Bloom. It was familiar because Sweetie had felt his penis with her inside place, and the feel of it on her tongue felt similar, though not nearly as tickly. Made her imagine she had a magic orgasm tongue up inside her, not like Apple Bloom’s tongue, but like Sweetie was a tongue down there... or at least she was something slimy and muscular.
If Snips could tell she was licking, it only made him drive into Apple Bloom harder, Sweetie’s dear friend giving swift excited cries of delight every time his penis just about dove into her. He later said he could feel Sweetie licking his balls, but his penis was too busy feeling Apple Bloom to be aware of any sneaky little filly tongue adding to the sliminess down there. It was an amazing taste, by the way. Snips made Apple Bloom’s tart apple flavor so much thicker and muskier, their scents blending seamlessly as their bodies were doing. Sweetie couldn’t help but touch herself like this, but she was really into what Snips and her friend were doing.
And she hadn’t even licked Apple Bloom directly yet.
Sweetie Belle pushed her nose urgently into her friend’s straining groin, and licked just the very edge of Apple Bloom where Snips was going in. It looked incredible how Apple Bloom just took him like that, her body the exact perfect shape for it. It kind of made Sweetie feel proud or at least confident of herself, because she could do that with her bottom too! A loud squeal burst out of Apple Bloom when Sweetie’s tongue grazed her yellow furred flesh, and most importantly, Apple Bloom’s inside place started contracting.
Just that one little lick was all it took to make Apple Bloom orgasm, she was so worked up by being fucked. And Sweetie knew just what to do in that situation. Her hoof gently stroked the tiny button of the convulsing groin of Apple Bloom to keep those contractions coming, then as soon as they slowed down, Sweetie went and took a little nibble on one of Apple Bloom’s soft teats. And boom, they sped right back up again. With Apple Bloom’s inside place so stretched right now, the complete loss of her bladder sprayed out stiffly against Sweetie Belle’s neck as Sweetie suckled her teats hungrily. It trickled down her fur in thin hot rivulets, and she could honestly care less because of what Apple Bloom was feeling right now. Apple Bloom was in too much pleasure to even squeal at this point, just quivering there silently while Sweetie and Snips kept her over the moon.
It actually made Sweetie’s heart ache, after Apple Bloom’s orgasm. She scooted out from under there to face her friend, and it made her heart ache, because Apple Bloom had such a quietly pained expression of bliss, like the amount of pleasure she was feeling was outright terrifying. So Sweetie went back to stroking her mane and kissing her, licking her friend’s ears like the mommy that Sweetie technically was. Apple Bloom focused on her with the most grateful smile, and even when Apple Bloom’s eyes narrowed at the squirts filling her up in there, Sweetie kept her firmly grounded until Snips was all done ejaculating into her.
Snips was actually mortified when he saw the state they’d gotten Apple Bloom in. He didn’t really understand how much Apple Bloom loved feeling this way, since he didn’t know her as well as Sweetie Belle. It was so fascinating though, Sweetie couldn’t help but ask why he hadn’t noticed Apple Bloom’s little freak out earlier, and he said that he could only think of ejaculating, once he got into it. It such an overwhelming need that Snips felt to do that. Sweetie wondered what it was like to ejaculate, and to only think of it. She had a lot of stuff put in her, but she had never had anything to put in another pony.
Except Rarity.
So Sweetie Belle lay there with an exhausted Apple Bloom’s head laid right against her side, and Snips was all too happy to help while they recovered, going to get the washcloths and towels and stuff. Apple Bloom didn’t want to wash off her inside place though. Once she’d caught her breath, she was fascinated with the goopy stuff Snips had put in her. Sweetie explained that it was his seed, and Apple Bloom said she knew what semen was, just never thought she’d have any inside herself. Sweetie said it was way different when you were in heat, but it still felt great. Apple Bloom didn’t know about great, to her it just felt kind of weird and slimy. Sweetie had to admit that was exactly what was great about it, but if you hadn’t been fucked so wonderfully by a lot of stallions, you might not yet associate slimy weirdness with amazing achievements.
Those two were who Sweetie ended up doing stuff the most. That very first stallion who raped her though, it turns out he was interested in her, well, in a fashion at least. His name was Caramel, and even after he learned that his foal was in Rarity’s belly he liked doting on Sweetie Belle. Taking her out on dates, finding little fun things for a stallion and a filly to do, and cramming his dick in her in a way a colt could never do of course. It was all really sweet and innocent, and Sweetie Belle came to be glad that her heat had provoked him into coming forward, because he really was such a great friend if you so much as gave him the time of day. Some others. Apple Bloom had apparantly finally cracked through Scootaloo’s shell, and she and Sweetie had something special planned for the pegasus pretty soon. But for now, Sweetie was content to just cuddle against her sister, and the foal inside of her who was part of Sweetie Belle.
