Sweetie Belle wasn’t sure why her bottom was so wet and tickly, but she was distracted enough to wander off from her sister a bit. She found herself standing by a stall of potatoes and carrots, her tail twitching restlessly to waft her scent around. She was surprised then when a strange stallion came up, and just walked right on top of Sweetie Belle, as if he didn’t see her down there.
She looked up and protested his rudeness, saying “Hey! What are you—” but then something prodded her very sensitive underside. making her tail turn aside reflexively to admit it against her soft flesh under there. She was so sensitive on her tickly bottom, but it didn’t make her want to squeal and giggle and cringe away like with other tickles. These tickles made her want it to ...touch her more? Then it hooked on something down there, and started pushing in, and met no resistence! She felt like she was wrapping around it.
“What are you doing?” she squeaked uneasily as that hot, soft but stiff thing pushed inside her. What was her bottom doing? Something was going inside it! Not just against it, but inside it. It just kept going in. It felt really good, but she wasn’t sure she was supposed to do this, so she walked forward trying to avoid getting in the way of his, whatever that was. However it got inside her, she still didn’t want to be rude to him and get in his way.
The stallion just put a hoof on her shoulder to stop her, and moved over her again, that hard thing sinking even deeper into her body. It was so deep, she could feel it sliding down underneath where her belly button was! There was no mistaking that! Sweetie didn’t want to move, with it inside her like this. She never knew her bottom had an inside place. That was weird, but cool! But what was he putting in there? This pole thing was filling her all the way, and it made her just want to stand there not going anywhere. She felt so stretched inside, and it made her feel peaceful somehow, like, satisfied. Then the stallion above her started shifting back and forth, and what that did was pull the thing out of her, then push it back in. The way it was sliding along her in there felt really weird. It wasn’t just sliding, but it was sort of tickly wherever it slid against her. It felt really personal and sort of scary. It was making her blush heavily, and her tummy was all fluttery. She didn’t know what he was doing!
Conversation drifted around the market as she looked around for confirmation that this was supposed to happen, but Rarity was still haggling with the celery merchant, and Cherry and Linky were just chatting with each other casually, and nopony else was really around besides this stallion. Sweetie had seen him before, he was the one with horseshoes as a cutie mark, but she hadn’t talked or anything. Then this big stallion just walks over her and puts something into her! What was he doing, and why was she letting him do it? She didn’t mind helping ponies, but this was her body! Should she yell or something? Was he hurting her? He was doing the opposite of hurting her though!
She felt something start to trickle down her leg, and Sweetie Belle lifted it trying to just let her juices drip to the floor. The way he was sliding his thing felt even better than his thing going inside, making her all tingly down there, and in there. It must have been so easy for him to slide like that in her, with how juicy she had been down there lately. And the tingling was way more than pleasant. It was distracting, and confusing. She wanted to see under there, but he had a good grip on her shoulder, so she could just barely turn her eyes back to where her soft white hips were quivering underneath his big ones. It felt like something weird and fleshy, like a hoof or a vegetable, but so warm, sliding so smoothly in and out, somewhere inside those blank flanks of hers.
“I... I don’t get it...” she said with difficulty. She was breathing really hard now. He still didn’t answer her, just did the sliding faster. Her face felt like she was going to burn up from blushing as the thing touched her so tenderly and specially. Sweetie Belle couldn’t help but give a little moan, it was so overwhelming. But still nopony seemed upset, so maybe this was a good thing to do. Then her doubts were driven into disarray, and her eyes crossed, as his modest sized length suddenly swelled inside her. She couldn’t believe how full she felt! Was he putting a... a water balloon in her?
He stopped sliding, just pressing up against her, and Sweetie looked up in disappointment saying, “Why did you stop? I don’t mind—” and then she cut off to stare forward, because the thing in her just started thrashing about. Sweetie sure loved that feeling. What was it doing in there? And then she gasped as a jet of fluid erupted from the tip of it, spraying all against her flesh in there. Had it burst? But then it squirted again, and then again!
“What’s... happening...” she panted, hunching forward with her eyes half lidded, as he shoved strongly against her, squirting stuff so deep inside her. Her round little hips were just filling up with that weird hot slimy feeling. The thing inside her stopped squirting then, and came to rest. Sweetie had one more minute to stand there wondering at her experience before he pushed off her, stepping back and that thing sliding out of her at the same time. It made a rush of fluid flood up from her depths, whatever it was he squirted into her.
Sweetie pulled away from the stallion, staring with confusion at her recently stretched vulva. Whatever had squirted in her was coming out in thin white glops. It smelled... really musky and good. It smelled like a stallion, not like Sweetie Belle. Curious, she looked where her hips had been a moment ago and hanging below the stallion was his... his penis.
Sweetie’s hooves braced unsteadily on the ground, as she saw his penis dangling there like he was going to pee, but he didn’t. Instead he twitched it, and it surged up stiffly like a pole underneath him. Sweetie became aware that the thing that had been inside her was this stallion’s penis all along. That was gross! Did he pee in her?! But it felt... really good. She didn’t realize penises were big and long like that so they could go inside her back there.
She went and scooted under him, figuring if he didn’t ask at first, there’s no reason to ask herself. She just pressed her bottom against that shaft of his, and tried to step backwards until he was comfortably inside her again. “Woah,” he said, backing off from her, his first words. “I’m tapped out. You should try that stallion over there.”
“Oh, um... thanks, I think,” Sweetie mumbled blushing embarassedly, walking out from under him. His penis stuff, that weird white pee was still dripping out of her, as she walked over to the nearest stallion, looking up at him with big eyes. Before she could even ask, there was movement under his hips, and she saw his penis start coming out. He smiled down at her and swiveled his hoof in circles, and Sweetie happily turned around, pointing her bottom in his direction, once again getting a long stiff fleshy thing pushed inside her.
It was funner this time. The other stallion’s goo made it even more pleasant feeling, and Sweetie’s blush deepened, as she understood now that it was a stallion’s penis sliding in and out of her. It didn’t seem gross, anymore. It seemed... powerful to think of his big penis pushing into her. Something was building in her, that made her belly all fluttery, and it just kept feeling better and better. She wasn’t sure how much better it could feel, but just the thought of more squirts inside her made her cry out in a clear peal of young desire.
As the second stallion started squirting inside her, a heavily panting Sweetie Belle looked out from under his legs to see a third already walking up. It was her... her crush, Big Macintosh. And his penis was already out. Sweetie looked up at Big Macintosh anxiously. Even if Big Macintosh didn’t want her to, Sweetie Belle had to stand so passively under the other stallion, feeling the squirts hitting her insides from the penis still jerking in there, looking up at her crush with trepidation. But her heart fluttered with relief as Big Mac had a non-judgemental smile on his face, even though it was another stallion’s penis pushed into Sweetie Belle. Sweetie couldn’t believe he was even paying attention to her. She blushed when Big Mac so much as hugged her. Sweetie Belle couldn’t imagine what she’d do when he put his penis inside her.
It was turning out to be a really good day.
When the second stallion let Sweetie go, she did blush, standing shyly before Big Macintosh. “I... I guess you want to put your penis in there too?” she asked, hardly daring to hope.
“Eyup,” he said, making her shiver with that deep voice of his. She looked at his penis, big and stiff and ebony, and she just couldn’t wait for him to spread her wide with that, and do that white slimy pee in her. What was happening to her was so gross, but somehow she just loved it! She actually liked stallions squirt/peeing in there, and making her insides all slimy felt really good. Plus it would be his slimy white stuff!
“You mean it?” she asked hopefully, turning to face away from him so that he could walk over her and do it. The white slimy stuff was dribbling out even more than her juicyness now, every time her bottom throbbed like it was flexing or, poking out or something. His response was to simply step over her, surrounding her with himself, and her breath caught as his penis poked her nethers. She shifted until his penis found the inside place too. How could she not? It was Big Macintosh’s penis! The very moment he penetrated her smoothly, the tingles threatened to overwhelm her, and she felt so brave and desperate. He was making her feel so good, she had to tell him!
“I... I like you!” Sweetie blurted out, her throat dry from all of the juices she was leaking out down there. It was like she was hugging him, his penis at least, and he was hugging her whole body. She tried to hug his penis as passionately and hard as she could, her tiny legs quivering as the squeezing caused an almost physical need to rise in her, to make him slide in there. She started rocking herself to slide him, but he stopped her with a hoof, holding her still. Sweetie was surprised at the quiet whine of disappointment that welled up in her.
“Y-y’like me? Like, like like?” he said above her.
“Yes,” she moaned, “I should have said, I... do you like me? Why are you doing this?”
“Talk later,” he murmured in a strained tone. His hips jittered and started to slide his penis out of her then, and back in. Out and in, out and in. Sweetie was free now, free to rock back against the resistence of his penis inside her, helping him pull out and push in. Together they did the... the thing that he wanted to do. Sweetie Belle helped him do it to her, as best as she could. She didn’t know why he wanted to do this, but now she wanted it too.
Sweetie Belle thought the best thing about Big Macintosh was his smell, like apples and old books. And she was surrounded with that smell when he went inside her. She couldn’t believe he was paying attention to her! Something about her new inside place was really special to him! Her whole body was tingling now, and her grunts were growing urgent as the sliding started to make her insides feel electric. She couldn’t even squeeze them now, couldn’t do anything but stand, everything just stilling back there for him to squelch wetly in. And every slide just built and built in her until it broke over her like an ocean wave. A surprised squeal escaped her as her inside place suddenly leapt into motion, contracting rhythmically around Big Macintosh’s penis. He shoved into those contractions, scooting her forward as she jerk, jerk, jerked in her hips, unable to stop it, or to even think. She loved her inside place! It felt so good!
The mind blowing waves of tingles eased off as her involuntary contractions eased off, and then she was just panting and sweaty, herself again just standing there under her favorite stallion. And he was putting his penis inside her. Why had her bottom felt so good just then? Did he like it? What was she even doing? Was it going to happen again? She just felt the sliding motion now, but it had a sort of echo of that clenchy tingle wave. She felt very pleasant and relaxed, and figured she wouldn’t mind if he peed in her there, because he made her feel so good so she wanted to pay him back in return.
“There you are, Sweetie!” Rarity exclaimed trotting over to Sweetie and Mac. “Oh, how adorable,” she gushed at Sweetie’s little predicament there. “You’re in heat! I hadn’t even realized. So young too, you lucky little filly.”
“What’s... heat...” Sweetie said with difficulty, her eyes wanting to half close from the ripply feeling that his penis sliding was giving her.
“Oh it’s a very special time in a filly’s life,” Rarity says, standing jauntily in front of where Sweetie was getting porked. “You’ll find the stallions all want to impregnate you. Clearly Big Macintosh doesn’t mind doing that even one bit.”
“Is that when he...” Sweetie’s eyes darted backwards, “Puts his penis inside me?”
“Oh, no no no this is just rutting,” Rarity said pinching Sweetie’s cheek as the little filly rocked there helplessly. “Impregnation is when he ejaculates in you.”
“What’s—” Sweetie couldn’t finish the sentence because Big Macintosh was getting big in her, so much it made her eyes lose focus. He stopped thrusting just to flare in her, stretching Sweetie’s inside place wide. She felt like he was kissing her in there. “...ejaculates?” she asked weakly. Then with a powerful heave of his hindquarters, Sweetie Belle was really fucked.
“Why, when he puts his seed in you, dear,” Rarity said with a gentle smile. Sweetie couldn’t ask more, because the relentless pistoning back there made her burst into another round of uncontrollable contractions inside her. She just looked at Rarity all starry eyed as his slide, slide, slide made her jerk, jerk jerk.
Rarity squeed at the sight, holding her forehooves together as she watched it happen to Sweetie Belle in utter delight. “Oh, an orgasm! You are a lucky little filly. It feels good, does it not?”
“So... good...” Sweetie managed to moan once her contractions began to still. She felt so much better about this now that Rarity was there at least giving her an idea of what was going on. So this was something she was supposed to do, and it was perfectly okay. She had been worried it was wrong, or that she was hurting stallions or something, or maybe it was a big joke, but if it was she didn’t mind because it felt great.
Big Macintosh slowed too, his thrusting going erratic before he pushed all the way into Sweetie again and held there, his penis thrashing inside her. “Oh my gosh,” she said to Rarity excitedly, as Big Macintosh started peeing his goop in there. It wasn’t peeing though, because it came out in jerky squirts, not one continous stream. Squirts that felt good when they hit her insides. “He’s doing the white peeing thing!” she eked out passionately. “Big Macintosh~!”
Rarity responded, by reaching under Big Macintosh and giving Sweetie a gentle hug throughout the process. Sweetie Belle had never felt better before today. Her crush was interested in her, and her sister was there supporting her, and she was in heat which meant that stallions could show her all about her amazing inside place, out of which Big Macintosh’s very own white stuff was leaking. She liked how it trailed along her pelvis back there too, and the wrinkly feel of him pressed against her surface... place.
“I think congratulations are in order,” Rarity said to Sweetie Belle, once Big Macintosh had pulled out of Sweetie Belle, leaving her inside place a quivering and gaping mess. He kind of... stood out of the way looking a little uneasy with the whole thing now. Sweetie tried to catch her breath, looking up at Rarity around the sweaty curls that threatened to flop flatly against her head. “You’re going to be a mother, now!” Rarity said to her cheerfully.
“A... what?” Sweetie asked dumbly. Before Rarity could answer she hastily clarified, saying “I know what a mother is. But I’m not going to be a mother. I’m just Sweetie Belle.”
Rarity laughed nervously at that and said, “Afraid it’s a tad out of your hooves at this point, Sweetie. You are going to have a lovely foal inside you,” She tapped her hoof under Sweetie’s abdomen, right where her... inside place ended. “Right about here. It won’t be long before your womb is huge with the foal curled up inside. At your age, I’d wager you have trouble walking with your belly that big.
“And then the foal will come out of you, and you’ll have to take care of it. You’ll have plenty of milk to feed the little dear, because that is your new daughter, or son,” Rarity continued. “Because believe it or not Sweetie Belle, you are a mother now!”
“I— but— a foal in there?! But there was just a pee.... thing in there, not a foal!” Sweetie protested, sitting down on her haunches despite the dribbly white mess that was down there. “I don’t want to be a mother!” she squeaked anxiously.
Rarity... hesitated in her joy at that. “You... don’t want to be a mother?” she asked disbelievingly.
“I... I don’t know, but...” Sweetie said prevaricating and chewing on a lock of her mane. “Can’t I wait until I get my cutie mark at least? Mother had hers, didn’t she? And what about school? I can’t carry a f-foal to my classes!”
“You certainly can, dear,” Rarity said somewhat grimly, “And any who oppose that will be swiftly disciplined, I assure you. But like it or not, you are becoming a mother now. You were a mother, the moment that stallion started ejaculating inside you.”
Sweetie blinked.
“Why did you think they were ejaculating into you?” Rarity asked uneasily. “You’re in heat, which means you can become pregnant. And that means that when a stallion ejaculates into you, it will turn your fertile egg into a foal, who will then begin to grow inside you. That’s what a mother is, you know. A filly who had a foal.”
“O-oh...” Sweetie said in a somewhat subdued fashion, standing up to look at the sticky mess of her groin. “So the white stallion pee turned me into a mother?”
“You can call it seed, dear,” Rarity said chastisingly. “It certainly is not ehm... ‘pee’.”
“But I look the same!” Sweetie said, looking up at Rarity seriously. “I’m not big or old or anything. I wouldn’t even know I was a mother or anything was different at all, if you weren’t telling me!”
“It will take a while before you notice any physical changes,” Rarity explained. “Generally first your skin tone will improve, and you’ll get much hungrier since you must build a foal inside you now. Odd foods too, since you’re growing a whole pony from scratch not just maintaining yourself. Before long you’ll see a little bump, and it just gets bigger from there! But for now you have simply to relax and enjoy the stallions, and the feelings your heat gives you about stallions, and wait for their seed to fertilize your egg. Once the egg is fertile, it will implant into your womb, and your body will provide for it until it has grown all the way into a foal!”
“What if I don’t want to provide for it,” Sweetie grumbled a bit resentfully.
“You wouldn’t be so cruel as to deny an adorable little foal a meal, would you?” Rarity asked aghast.
“It’s not a foal though! I mean, it’s just... can’t I stop the egg?”
“Going into heat means that your egg is already on its way,” Rarity said, undeterred. “With all that seed inside you, I’m afraid it’s a foregone conclusion. You may as well enjoy it at this point.”
“Well,” Sweetie said in frustration, feeling all that slimy stuff inside her with a more fearful context now, “Maybe I just won’t let any stallions put their seed in my inside place then!”
“Sweetie, how many stallions have ejaculated in you so far?” Rarity asked in a deadpan.
“T-three but,”
“Only three? My, you certainly haven’t been busy in that regard,” Rarity says critically, making Sweetie’s chest flare with hope. “But just one drop of seed is all that is needed,” Rarity continued, making Sweetie sag in disappointment. “You fuck—er that is, you have a lot of stallions ejaculate in you, in order to give everypony’s seed an equal chance to reach your egg. But only one is necessary, and three are certainly sufficient!”
“Why didn’t you tell me before they ejaculated in me, then?” Sweetie asked in sheer exasperation. She couldn’t believe she had a... an egg in her, like a chicken? And all that white seed was like, planting inside her? Her inside place felt good, but she didn’t feel anything planting in there. Would she even feel it?
“Oh, well, em...” Rarity blushed looking to the side. “I confess I rather like foals and, never managed to go into heat myself. I figure a filly won’t mind just the one time being a surprise, so I try not to forewarn any filly, and just leave things to happen naturally. But heat is very rare. Normally you can have stallions ejaculate into you all you want, and no foal will appear no matter how you want it. If I had known you would harbor such doubts, I would have told you straight away! I didn’t even realize you were in heat, until you’d been rutted by almost three stallions, anyway. Honest mistake?”
Sweetie grumbled unhappily, pushing at her naturally round tummy as if she could squeeze that foal right out of her.
“Look, Sweetie, I don’t mean to understand where you’re coming from,” Rarity said appeasingly, “It is admittedly perhaps a bit of a shock,”
“Just a bit!” Sweetie declared.
“Tell you what,” Rarity said, helping Sweetie to her hooves. “How about we both go rutting stallions, now that your body is ready? With you in heat, that should aid them in rutting me as well, after they’ve put their seed in you. We can take the whole day off together to do this.” Sweetie would have outright just refused, and been really mad at Rarity at that point. But Rarity continued further saying, “By tomorrow, your egg should be well fertilized, and we can visit my friend Twilight Sparkle. She happens to know a clever little spell to teleport an egg from one womb to another.”
Sweetie gasped, looking up at Rarity in shocked realization, “But you’re not in heat!” she said.
“I may lack the necessary egg,” Rarity stated, “But I certainly can care for a foal in my womb as well as you can. I’ll bear your foal to term, and if you are unsatisfied with the result, I will raise them as if they were my child. If it’s from your egg, the foal will be a lot like you. It’ll be like having my own little Sweetie Belle as a daughter! Or a son, perhaps. But even as a colt, I’m sure your child would be absolutely darling.”
“I... I can’t ask you to do that, Rarity...” Sweetie said in a quietly sheepish tone.
“Oh, but I want to!” Rarity responded, placing a hoof on Sweetie’s chest. “I was not being facetious when I said I liked foals. Plus this was my fluff up for not realizing you wouldn’t be as comfortable with the idea as I was. And really Sweetie,” She looked Sweetie in the eye, celadon green meeting royal blue, “I think once the foal comes out where you can see them, you’ll find it a delight to involve yourself in his or her life. If you find joy in it, you’re fully welcome to consider yourself the foal’s mother too.”
Sweetie considered, and found very little problem with the idea. It’d be a big change for Rarity, but if Rarity was okay with it... Sweetie could sort of help her out then? Sweetie Belle’s hips felt like a trap after Rarity told her, but now they felt like a... thing she could use to help Rarity. If she could make an egg and Rarity can’t, Sweetie would love to give it to her sister! “I... I guess that... that does sound really nice,” Sweetie said.
“Did I mention it means you could put more stallions in... how did you put it, your ‘inside place’?”
“It was weird at first,” Sweetie confessed a bit nervously. “But it started feeling better and better, and then the um... squeeze... jerky thing...”
“Orgasms, dear.”
“If I could keep having orgasms,” Sweetie clarified, “And I could give you a foal you want, and a part of me could be your little Sweetie Belle, it just sounds too good to be true!”
Rarity combed through Sweetie’s mane tenderly with her hoof groove. “The world does tend to be a rather nice place, once teleportation is involved,” she said admittedly. “I am sorry for not knowing you well enough to nip this problem in the bud.”
“No, it’s okay,” Sweetie said, rubbing up along Rarity, and this being in heat thing even made her cheek rubs feel tingly. “If you had, then I still would have put seed in my bottom, if it can help you out, and I won’t get teased at school or have to worry, and... those stallions started feeling really good (I can’t believe Big Mac went in there!)”
“Then let us go!” Rarity exclaimed, facing forward into the light of day. “We shall leave no stone unturned! No stallion unaided. Together you, I and your heat can make waves in this town, and by tomorrow you will surely have the very best foal in your womb that can possibly be!”
“A-and then you’ll help me out, right,” Sweetie prompted.
Rarity actually giggled indulgently at that. “A foal in my belly,” she said eagerly, dancing on her hooves. “I never thought I’d feel it. I confess, when mother was pregnant with you, I was so very jealous of her. You were all curled up there in her belly, in her womb, and I simply couldn’t do a thing with my own.”
“Okay, I’ll do it,” Sweetie said determinedly, even a bit eagerly, crouching on her hooves to gallop with Rarity into the sunset. A hoof tapped her on the shoulder.
“Sorry to bother y’all,” Big Macintosh said, “But before you run off, you might want to take into account that you already got a line formin’.” He pointed a hoof at the several stallions who’d all assembled, one after the other in a neat line behind Sweetie Belle. She could already see some of their penises coming out and twitching around under there.
And sure enough, it was a really good day.
