Public Heat

 

Generosity

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. She had to breathe hard, because of those intense feelings flowing from that pistoning thing in her bottom. He still didn’t answer her, but just did the sliding even faster when she said it. 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. It wasn’t water that’s for sure. Something that came from his... body, was coming out of her now? She must have been feeling him put it inside there! 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. She knew pee was gross, 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, and another stallion’s pee just filling her up inside. 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! He pushed strongly as soon as she did, sliding in slickly and making her bottom stretch wide all the way deep inside. 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 still sliding 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.

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Musing

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 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.

 

“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, “For you, Rarity...”

 

She slid her eyes open at Rarity’s whimper, to see the blue stallion, Noteworthy apparantly his name, now fucking Rarity heartily. Rarity was just like Sweetie Belle, but he could really grip her rear as he hammered into it, her expression almost pained, but Sweetie knew how it really was 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. “Five 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.
