Sweetie Skips Estrus

Scootaloo was true to his word, cleaning Sweetie inside and out from that day on, until she could barely squeak out his name, every single time he finished in her. And he finished in her every time. He never got tired of finishing in her. In fact, once they were trying to play around with just rubbing, and he had to jump up and say it was making him want to be inside. Sweetie didn’t want to admit the powerful urges her own insides were crying for, the more she touched them, so she just lay there with her legs spread welcomingly, and maybe a bit of an urgent expression. Scootaloo took care of her, put his penis in, and thrust to climax. He just stared intensely into her eyes, even as he throbbed beneath her, filling Sweetie Belle with his pulses of seed. Sweetie orgasmed from those vivid purple eyes alone, no less from what she felt happening inside her while she gazed at them.

Sweetie couldn’t believe it herself, but she... started really enjoying making her insides totally messy. She didn’t want to admit it, but Scootaloo finally caught her feeling like that. It was one time that he finished his colt thing, and shoved against the quivering filly, starting to ejaculate into her. “M-more~” Sweetie moaned desperately, her plea answered with more delicious pulses inside her.

“What?” he gasped breathlessly, making Sweetie wince self consciously, even as his squirts tapered off all too quickly, Scootaloo still holding himself hunched over her.

Sweetie wanted to die from blushing. “I–I don’t know,” she said nervously. “I just really, really, really ...don’t mind feeling your stuff s-squirting in there.”

“It sounds more like you really like it,” Scootaloo said in a wry, very unconvinced tone.

“I really like it,” Sweetie let herself groan out. She didn’t understand why, not even when Scootaloo licked her and she begged him to leave it all inside her. Sweetie just found herself wanting to cry from the joy she felt when Scootaloo finally got those words to tumble out of her. It didn’t feel good, just slimy, but Sweetie Belle still really liked it, just the thought of being full of it as long as possible.

Sweetie Belle thus stopped trying to get Scootaloo to lick it out from inside her. She confessed that to him the next time, after his seed filled the immature unicorn once again. Sweetie felt the hot blooms spread in her hips, and she felt that strange satisfaction again, at having that weird messy stuff inside her place. They were just cuddling after and he asked her if she really was okay being all messy like that, way up inside.

“I really don’t know why I like getting so messy inside,” she confessed to him, touching noses shyly. “It just feels really... slimy in there! I don’t know I can’t explain it.”

“You just like having a bit of my awesome in you,” Scootaloo said with a rakish grin. “Okay I won’t lick it out of you, then.” And boy did he lick everything else, though.

Sweetie sort of changed her mind on the benefit of carrying Scootaloo’s goo within her, after she found that Scootaloo’s goo would dribble out unexpectedly at inopportune times. She swore she was just sitting in there class listening to the teacher, and then just felt a sort of ‘glub’ down there. Sweetie Belle was so embarassed and she didn’t even have any tissues with her. Writing paper was very bad it turns out, at absorbing Scootaloo stuff. It also crinkles noisily when you try to slip it subtly into that chubby round white V your pelvis makes, between your broad, white furred legs.

You know, assuming you’re Sweetie Belle, that is.

It was easy enough for Sweetie to start timing it so Scootaloo would do it on the weekend though. That way, Sweetie Belle could dribble and nopony would notice, except maybe Apple Bloom who was polite enough not to give her a hard time about it. Apple Bloom was kind of worried Sweetie was sick in fact, but Sweetie made sure her friend knew she was feeling absolutely fine.

When they first started doing this penis thing, Scootaloo could only get it up for once a week or so at first, but as his penis was plumping up so attractively, he started wanting to do it more often. Sweetie was still okay with once a week, but even she started to feel sort of a teasing ache in her more often, for a certain pegasus’s special inside touch. Nevertheless, they usually did it only once a week, making their improvement at mating with each other slow and fumbling, but steady.

When the darkest night came, Sweetie also lifted her tail for Scootaloo. It wasn’t like this bottom thing was all they ever did together anymore, but when that horrible demon said those horrible things, then just vanished into an oozing starry mist, there was a certain urgency to their actions. Both of the foals were completely convinced that they might never be able to do this again!

When the three foals found themselves a hiding place on that terrible night, and Apple Bloom went to check outside, to see if any more star monsters were creeping their way, she returned to find Scootaloo just humping desperately into Sweetie. The two practically fell apart from each other, right when Apple Bloom came in, saying the coast was clear. Sitting there trying to cover their genitals, it just seemed so terrible to them the way Apple Bloom looked so sad and left out, when she turned away and said she would guard the door while they finished. Sweetie looked at Scootaloo, who looked at her equally unhappily. Then they started fucking again.

They should have told her. If they were smarter foals, or knew more, or were aware of what they would later learn, Apple Bloom would have known in an instant everything that they were doing together. But they were just unsure, stumbling children, trapped in an endless night, with only the comfort of intimacy left to warm them in the absence of the sun. So Sweetie Belle and Scootaloo just quietly fucked, and once their urges were satisfied, brought Apple Bloom in, and just hugged her and huddled together, not even caring about their messy groins, and not even thinking that Apple Bloom’s groin might itself be feeling a hunger to be made messy.

That might have been the morning when Apple Bloom learned the truth. But when the rays of the rising sun reached these little foals, they stumbled to their hooves and ran outside right away in excitement. The night mare had said the sun would never rise again, so when it did, it filled them with such joy and hope that the three forgot all about talking about what sort of secrets they’ve been keeping from each other. They just all gallopped as fast as they could to their folks and kin, and Scootaloo ran along too. No, Apple Bloom hadn’t found out, and now with a bright summer coming up, the need to tell her just didn’t feel as urgent as making big plans, for what they were going to do to get their cutie marks.

It was only a once a week thing, anyway. The three of them played ball together a whole lot more than that!

The coming summer meant less school and more fun days. It meant long days of bright adventure, and pleasant, warm nights. It meant not having to worry about a dribbly inside place in school. But even in their last days of regular education, Sweetie could still revel in what she and Scootaloo did together. That thought alone was enough to warm Sweetie’s tummy, like when she was sitting in class on her own. The thought came to Sweetie Belle unbidden, that there hunched under her own desk, inside her own white hips that looked totally clean and untouched, Scootaloo’s slimy stuff was with her always, even now.

When all the fillies in Sweetie Belle’s class started to synchronize their estrus that summer, Rarity decided it was time for the birds and the bees chat. And she was ready to spare Sweetie no details, such that the filly wouldn’t end up making a mistake in her first fertility season. She cornered Sweetie away from her little friends to save the poor filly the terrible embarassment, on the guise of preparing Sweetie a new dress for the relatively distant Harvest festival. Sweetie looked absolutely radiant for such a little filly even in the way she wore the practice forms. It was obvious that estrus was already working its magic on Rarity’s dear little sister. Now the only difficulty was with getting it to... stop working its magic just short of the point that Sweetie ended up in a situation she did not want to be in.

Thus, instead of walking into the private dressing room with a new dress for Sweetie to try on, Rarity came in bearing a rather important package, subtly concealed wrapped inside the ringlets of her tail. Sweetie saw no dress, and looked up at Rarity curiously, but before she could speak Rarity told her,

“Sweetie, your teacher saw fit to mention to me something about your class today.”

Sweetie’s ears tilted down, and she moaned, “Oh no, I don’t think we got in trouble. Was it because I spilled my milk? I cleaned it up really good!”

“No, no Sweetie you are not in trouble,” Rarity confirmed to the relieved filly. “In fact, Miss Cheerilee came to me with some most wonderful news!”

“Ooh, what’s that?” Sweetie asked eagerly.

Rarity smiled, and answered simply, “Why, Miss Cheerilee told me that you, among other fillies in class were going into their very first estrus this year!”

“Oh,” Sweetie said disgustedly. “That.”

“It’s nothing to be ashamed of Sweetie,” Rarity told her gently. “You must simply adjust your behavior a good deal to keep yourself safe.”

Sweetie shook her head, saying, “No, I’m not ashamed. It just was happening to Apple Bloom pretty bad. I think she’s starting to feel really bad.”

Rarity’s smile firmed, and she said, “Yes it... well it can be bad I suppose, in some sense, but Apple Bloom is an Apple do recall. They don’t have large families for no reason, after all. Their estrus tends to be on... well, something of a different level. But don’t you worry, Apple Bloom has her sister, and her grandmother to make sure she knows how to manage herself and avoid any unnecessary accidents.”

“And her brother,” Sweetie said in a gratified tone. “I bet he—”

“NO, no no Sweetie,” Rarity interrupted a little hastily. “Apple Bloom’s ...brother can under no circumstances help with her estrus.”

“What? Why not?” Sweetie asked with a frown. “Is he going to have to move out again this year?”

“Yes, Sweetie, I’m afraid he is,” Rarity said with a sigh. “As wonderful as estrus can be, it is the one time of year when mares and stallions must not mix company.”

“So... you mean like... hang out?” Sweetie asked uncertainly.

“Yes. Hang... out,” Rarity said with a note of disgust at such a near vulgar way to describe the intricacies of pony romance.

“I guess Big Macintosh moves out every year?” Sweetie asked in an odd note of disappointment.

“Yes, he stays with a pony in town for estrus,” Rarity qualified uneasily. “Don’t you remember last year?”

“Yes, but I don’t really remember before that very good,” Sweetie said somewhat glumly. “I remember my birthdays, and meeting miss Cheerilee, and Hearth’s Warming and... not much.”

“I wouldn’t worry about it too much, Sweetie,” Rarity said. “Just cherish what memories you have.”

“I remember my bottle,” Sweetie admitted. “That had to be a lo-o-o-ong time ago.”

“You were weaned by 2, if I recall” Rarity said helpfully. “But you did return to the bottle now and then from there, until you were ready to drink from a glass.”

“So okay, he always moves away,” Sweetie pondered regardless of Rarity’s nostalgia, “And I guess miss Cheerilee makes fillies and colts take a different recess when the estrus starts for us too. So... colts and fillies can’t be together, for some reason, because of estrus?”

“Why yes, Sweetie,” Rarity said to the confused looking unicorn filly standing before her, glad to finally be able to introduce Sweetie to the wonders and terrors of marehood. “There is a good reason you cannot be with any colts for the duration of this month. Do you know how foals are made?”

“I um... in mare’s bellies, I think?” Sweetie mumbled uncertainly, looking back at her own hindquarters briefly.

“Well yes, that’s where the process occurs,” Rarity admitted, drawing her dearest little one’s attention back to herself, “But your belly won’t just start producing a foal just like that. Oh no, no. You see, colts have a special seed within them. I’m sure you’ve found the estrus you feel draws you more to their... male organ. The penis, that is.”

“Yeah,” Sweetie said with a silly smile. “They’re amazing.”

“Your belly won’t start producing a foal just like that, oh no no,” Rarity said, drawing Sweetie’s attention away from her own belly. Sweetie Belle hadn’t really thought about it before, but if foals are made in mare’s bellies, then Sweetie’s belly might have one in it, when she was grown up and like Rarity of course!

“Colts have a special seed within them,” Rarity continued. “I’m sure you’ve found the estrus you feel draws you more to their... male organ. The penis, that is.”

“Yeah,” Sweetie said up to her sister with a silly grin. There was one penis in particular, that had been making her estrus really easy so far. She didn’t even feel flushed or itchy at all. “They’re amazing.”

“Well—” Rarity said, lifting a flustered hoof, “As erm, ‘amazing’ as they may be, it turns out a colt’s penis is not simply for urinating. You see, he can produce urine, but in the right circumstances, he will produce something else entirely.”

Sweetie blinked owlishly at Rarity. She knew all this time? Maybe she knew what the stuff was then.

“It’s his fertile seed,” Rarity hoofily explained. “Not seeds like you’d find in a plant, but a rich white creamy substance, that has in it countless erm... tiny little things that carry his essence. What he will try to do is put his penis inside you. In fact, your filly parts have a place just for his penis to fit in! Good news if you wish to have a foal, but not good news if you are a little filly. When he has his penis inside you, that cream will come out of it in bursts, and the tiny little attendants in it will wriggle right up inside you and penetrate your egg.”

“Without that male seed, your egg will never become a foal, as harmless as a little speck of dust,” Rarity continued. “But as long as the egg is there, and you are not yet pregnant, you will feel the heat of estrus. It’s your body’s natural desire to try and unite that egg with the seed it needs. Like every animal even we ponies feel the call of nature, and however we become pregnant, that is how the next generation of ponies comes to be.”

Sweetie was feeling quite worried, as Rarity went and laid a hoof on Sweetie Belle’s belly, right where the end of Sweetie’s special inside place would be. “Right around here, you have a very fertile womb right now, and if a stallion’s seed meets with your egg, your estrus will cease, and a foal will begin to grow in there. And that is why you must not spend any time with either a colt or stallion during your estrus, because this is when your egg can potentially be fertilized.”

Rarity strutted away, saying wryly, “You might think you could just... not put his penis in. It must sound terribly strange to think that you would ever take a fleshy organ like that and thrust it into your own body. But that’s the sneaky thing about estrus, is it makes you hunger to be filled. In fact, when in heat if I must be with a stallion, and refuse to allow him to impregnate me, I can tell you it is one of the most difficult things a filly can ever do. It’s more attractive than ice cream, jelly beans and chocolate combined.”

Rarity then brandished a ...rather nicely slim looking box with a rather nicely slim looking dildo inside it. “Which is no problem, if you use this,” she said presenting it to Sweetie with a flourish. Sweetie took it on her hoof, looking at the picture on the front that resembled Scootaloo’s... fertile thing, with a growing amount of dread. “Consider it a gift from me,” Rarity said happily, “To celebrate how mature you are becoming! With this you can use this to satisfy your urges, and simply not interact with any colts until the season has passed. Without their pheremones addling your senses, estrus can be a very enjoyable experience. You must simply exercise some caution and care with who you end up in a room with.”

“But I don’t think I even have any um... eggs inside me?” Sweetie said hopefully.

“Oh, you certainly do dear. Perhaps not eggs like a hen, but simply quivering tiny bits of potential inside you,” Rarity said with a poetic mane toss. “You may not know of them physically Sweetie Belle, but you are in heat. As long as this season lasts, you will be producing quite fertile eggs, and you are in grave danger of becoming pregnant with a foal.”

“What if he fills you and you’re not in heat?” Sweetie asked desperately, clutching the boxed dildo to her chest.

Rarity blinked at that, and said, “Oh, well I suppose it doesn’t matter then, but you’re still quite young to be in a relationship like that. But yes, the only thing that matters is whether he puts semen inside you during the heat period.”

“D-does it always work?” Sweetie squeaked out.

“Well, no,” Rarity admitted. “You certainly might have to do it two or three times. But one certainly can be enough, it’s the luck of the draw really. You’ve only been in estrus for a week though, so surely you haven’t gone and presented your rear to stallions already?”

Rarity blinked at the air, then peered at Sweetie Belle more seriously, seeming to notice the filly’s nervous agitation for the first time. In a flat deadpan she asked, “You didn’t, right?”

“I think I know why I haven’t been feeling estrus now,” Sweetie whimpered.

“How many?!” Rarity exclaimed suddenly in her face.

Sweetie squeaked with alarm falling back and stammering, “H-how many what?!”

“How many stallions?” Rarity asked intensely.

“J-j-just one,” Sweetie said miserably.

“Who?” Rarity said, practically shaking Sweetie Belle, “Who did this to you?!”

No wait, literally shaking her.

“P-p-p-please Ra-a-rity we di-idn’t know!”

Rarity held Sweetie at hoof’s length critically, then pulled her into a crushing hug. “Oh Sweetie, you didn’t know, but the stallion surely did. I can’t believe some awful beast deceived my dearest little sister right under my nose!”

“He didn’t though!” Sweetie protested, “He didn’t!”

“Sweetie, the very idea that a stallion isn’t fully aware that he will—”

“It was a colt!” Sweetie shouted.

Rarity paused and... pulled away from Sweetie, facing her serously right on the floor of the kitchen there. “Even so, colts are warned as well by their parents. But perhaps they missed estrus coming too, and...”

“H-he’s an orphan,” Sweetie said with a sniffle. She could even feel Scootaloo’s goo in there, right now. They just did it. It was sliming her up a-and she was... her eyes grew distant as the pudgy little unicorn filly couldn’t help but imagine it in there, busily wiggling up inside her belly, making Sweetie Belle a mommy.

“Then the orphanage,” Rarity went on, “Has a very good program for educating fillies and colts on what’s happening to their ...lower parts.”

“He skipped it,” Sweetie mumbled. “W-we thought we already... knew...”

“B-but that was months ago, Sweetie,” Rarity said faintly, “How long have you...?”

“Since um... Fall...”

“Last Fall? But that was almost a year ago!” Rarity exclaimed.

“N-no the year before that...” Sweetie mumbled.

“Who is this Sweetie?” Rarity asked desperately. “You haven’t been... all this time, but... what colts do you even interact with?”

Sweetie Belle felt so guilty. It just made things so much worse, Rarity not knowing about this. Sweetie didn’t want Scootaloo to get in trouble, but... but if Scootaloo put his seed in her, then that means she’s going to have a foal now?! That’s like, a baby, that mommies have! Sweetie couldn’t just do that by herself! Even with Scootaloo, they both couldn’t handle that alone, not even together! Sweetie couldn’t have a—a foal in her belly. They needed help... more than she ever dreamed she would need.

Sweetie swallowed, then admitted, “It’s Scootaloo.”

Rarity looked blankly for a moment, before her face broke into a gentle smile and she said, “No, no Sweetie. It’s not dangerous for two fillies to be with each other, even if you are intimate. Only a colt has the seed that can fertilize you.”

Sweetie Belle blinked at Rarity. “Scootaloo’s a colt,” she said frankly.

“Scootaloo is a filly,” Rarity insisted pleasantly. “She and Apple Bloom are your two filly friends, and they have always been fillies!”

“Ugh,” Sweetie rolled her eyes. “Scootaloo was right. This is really annoying.”

“Ewha?” Rarity seemed nonplussed at Sweetie’s disgruntled reaction.

“Everypony thinks Scootaloo is a filly,” Sweetie said in annoyance. “So he has some feminine features, that doesn’t mean he’s not a colt! Just because he’s my friend doesn’t mean he has to be a filly!”

“You must be mistaken dear,” Rarity said appeasingly, with a desperate smile, “I think I would have known if Scootaloo had been a colt all this time.”

“Trust me sister,” Sweetie emphasized, “I am one hundred percent certain that Scootaloo is a colt.”

“one hundred percent...” Rarity said weakly.

“It was an accident!” Sweetie exclaimed throwing up her hooves. “We were just I mean, we were just kissing and my bottom started... doing the filly thing, and Scootaloo loved to lick it. But he stopped licking and was just hugging me, and then our... things fit together. H-he didn’t even make seed at first, and I should have stopped then if I knew, but then it started to come out of him. He didn’t even want it to; he couldn’t help making the seed come out! A-and I liked it because it was so... messy when he did it... inside...”

“We were just having fun,” Sweetie pleaded, “I don’t want to be pregnant!”

Sweetie Belle looked at Rarity beseechingly. Then Sweetie blinked.

Then Sweetie stood up, and trotted over to Rarity. Sweetie waved a hoof in front of her sister going,

“Rarity? You okay? Raaaarityy?”

Rarity’s reaction was suspiciously happy. Once she recovered from... that, Rarity smiled broadly and hugged Sweetie close to her, and said that Sweetie was such a lucky little filly to be experiencing this Celestial miracle of foaling on her very first estrus. Rarity promised Sweetie up and down that Sweetie Belle would never go for want while she had the child, and that Rarity would make sure her every need was cared for.

“I don’t need that much!” Sweetie said in nervous irritation. “I don’t even feel different yet. Just not... estrusy.”

“Estrosian is the proper Ratin term,” Rarity said smartly. “You will feel different though, very soon. With your foal planted inside you, you will feel a powerful need to care for the darling little thing. Just think of her as nestled up within you, needing your body to help her grow big and strong. You will have to eat more, and trust me you will be hungry enough to feed two ponies. And as you progress over the next year, you’ll start showing!”

“Showing?” Sweetie said with a gulp.

Rarity just raised a hoof to lightly lay against Sweetie’s all too sensitive belly, saying to her in a gentle tone, “Just a little bump at first, an extra tightness about your barrel. But then you’ll hardly believe you’re changing so much, not even feeling the changes as your belly grows more and more every day. At your size Sweetie, you’ll likely wake up one day and find the foal in you has made it near impossible to walk!”

Rarity hugged Sweetie again, and said to her passionately, “But worry not. Your sister will be there to look out for you! You just say the word, and she will do whatever it takes to ensure that you and your foal get just what they need.”

Sweetie hugged her sister back, and felt so loved and relieved that Rarity would do this for her, but also felt... strangely unsatisfied. Because Rarity would not say one bad thing about this. Rarity clearly hated the idea of Scootaloo doing... that inside her, but it was a good thing somehow, even if Sweetie ended up not even able to walk? And it didn’t just end there either. Sweetie would be so humiliated at school, and there’s no way a baby foal was going to be quiet and well behaved during her classes! Sweetie Belle loved her sister and her support, but kind of wished Rarity would be a little less... happy about it. Because that way, Sweetie Belle wouldn’t feel so insecure about her own unhappiness she felt inside her.

The worst part is Sweetie Belle was really happy about it too. The way Rarity described that adorable darling little foal curled up inside Sweetie’s tummy all warm and safe, it made Sweetie feel all fuzzy and warm inside. Foals were so cute! But on the other hoof... let’s just say Cutie Mark Crusader Foalsitters did not go well. As it really started to hit Sweetie that somehow she and Scootaloo had gone and made Sweetie Belle a mommy, Sweetie Belle really didn’t feel good about being a mommy, even though she did. It was a really confusing feeling.

That’s why Sweetie Belle remained silent to Scootaloo on the issue, until she lay there supine on her bed, giving Scootaloo an approvingly excited look, while Scootaloo eagerly hopped up on her, penetrating her like the colt he is. He was all ready to fill her up with the stuff that Sweetie now knew she shouldn’t have let anywhere near her inside place. Yet despite her dark thoughts on the subject, Sweetie loved being penetrated so very much, especially this way. Watching him feel it as he went into her, watching him do it between her own legs. A look of pure bliss crossed Scootaloo’s face as he sank into Sweetie’s welcoming depths, and Sweetie was sure that the same expression filled hers.

Depths that were too welcoming, she knew now, but it was too late anyway. More seed wasn’t gonna put more foals in her. Rarity was clear on that, that Sweetie’s troublesome eggs would stop coming out, as long as she was already with foal, so she must under no circumstances do anything with Scootaloo ever again.

Rarity wasn’t making all that much sense at that point.

Sweetie did do it with Scootaloo again though, because she wanted to see if he’d do it. Really really do it, not just by accident. She wanted him badly, and she wanted his... support or something. When Sweetie thought of the consequences of having a foal, she still wanted a penis inside her, and secretly, guiltily to herself, she wanted Scootaloo to be that way too. Sweetie wouldn’t be the only one who was feeling stupid like this, if colts also felt this way. So Sweetie Belle had teased Scootaloo with her filly scented tail the moment they walked into the house, and snuck him into her safe little bedroom, and spread her legs for Scootaloo, so he couldn’t not put his penis inside.

Sweetie Belle’s bedroom was unflatteringly safe, because her parents were away... again. Rarity and Sweetie still had access to the house, but Rarity mostly lived out of her boutique these days, and Sweetie... really didn’t like sleeping in an empty house, so she stayed with Rarity. It worked out good though, because Rarity was more than happy to help Sweetie with her struggles as a growing schoolfilly, and that meant when Sweetie Belle needed the private intimacy of a familiar safe place, to do the foal making thing belly-to-belly, she and Scootaloo had a nice soft bed to do it on, that nopony would walk in on or hear them doing it.

Sweetie still preferred the convenience of that emptied out shed for just being mounted on top of, but for belly-to-belly nothing beat the smooth feel of her cool sheets on the fur of her back and hindquarters, as the loving pegusus spread his wings above her, and plunged his young shaft into her quiveringly eager nether parts. Doing this always made Sweetie feel good all over. When a penis was sliding on her in there, the rest of her felt so tingly it made sheets, and hooves, and tongues, and everything touching her all over feel good. She just liked hugging Scootaloo close to her, to feel his chest fur tickle hers, as her bottom’s inner action unlocked the good feelings in her whole entire body.

Sweetie loved doing it face to face like this. It wasn’t as animalistically satisfying as letting him mount her from behind, but this way she could see his eyes, she could see him make those gasps and grunts, and she could see her own hips, devotedly penetrated by his sliding shaft. It just vanished into her, something Sweetie never ceased to find fascinating. She had loved how her body could just contain Scootaloo’s penis like that, just by spreading her legs for him. How he had to shove against her so intensely, Sweetie now knew for ensuring that his seed got her as pregnant as possible.

She didn’t just have to hear the cute little squeaks he gave, fucking face-to-face. Sweetie Belle could see him making them, see him being that way for her. How his penis felt was squirm inducing in of itself, but when she could see how her place felt, telegraphed in every inch of Scootaloo’s body, with every loving thrust he made in her, that just made her hips want to explode in pleasure. She could see how her legs wrapped around his thighs, how his thighs worked her so smoothly, how his belly flexed and pressed against hers, how his eyes looked so fiery with intense desire.

And he too could see her half lidded eyes, and huffing breaths, and hunger to accept him into her. They could gaze at each other, or stare at the source of their union, lost in lust as they squished their hips together in that all important pistoning motion that would make Scootaloo push into her and start squirting white stuff.

But for now, they kissed. Sweetie Belle liked kissing in general, because they were so close together, and her lips were so sensitive as his softness met her own. It was something they had in common. He was so different from her where he entered her down there, and so similar to her up here. Up here, she could touch her tongue to his, and he to hers, but down there only he had the thick fleshy key for fulfilling her inner needs. They could take each other, face to face, but groin to groin Sweetie felt more like she was being taken, the burden of motherhood thrust upon her, not an inch of her insides able to resist his hungrily pistoning shaft, spreading her around him heedlessly, seeking to seed himself deep within her.

As they kissed, Scootaloo started thrusting right away. They had to break the kiss, for Sweetie to pant at the blissful intensity of her bucking hips, and for Scootaloo to gasp with the effort of pushing his penis in and out. It was an easy task physically, but this good of a feeling was exhausting in of itself. That was why sometimes, even after only a little bit of thrusting, and Scootaloo’s climax of course, he and Sweetie would sometimes drift off to sleep together right away, unconcerned about his softening rod still in her canal, and his seed dribbling out around them.

But Scootaloo couldn’t sleep yet. Scootaloo couldn’t relax not even for one moment, because he had to... he had to put a foal in her. That sneaky penis Scootaloo had was making him feel so good, because he was a boy, and Sweetie Belle was a girl. Because of that, his penis, and her va...thing that Rarity called it, were both tricking them into making a foal. Sweetie knew now why Scootaloo had forced her to take his seed that time. The last time she ever tried to refuse him. He didn’t want to hurt her, Scootaloo was just too smitten by the feelings, that felt even better when he obeyed his urges. He just pushed Sweetie down and... and showed her how much she loved his seed.

And he didn’t even know...

It was scary, but also kind of thrilling to Sweetie Belle that Scootaloo didn’t know about this. He was sliding in and out and he had just the most adorably blissful look on his face; he looked so heart achingly innocent, doing this amazing thing to Sweetie Belle without any compunction. She was carrying his foal, and she hadn’t told him. He didn’t even know. He was a daddy and she was a mommy, and he didn’t even know it. Thanks to Rarity’s belated advice, for Sweetie now, they were making a foal. For Scootaloo they were just squirting in Sweetie’s hips, and making each other feel good.

Scootaloo probably wouldn’t even do this penis thing with Sweetie Belle anymore, if he did know. He’d probably get mad at her, and tell her that she was bad for wanting it, even when she knew it would make her have to stop school and raise a foal and stuff. But as long as the magic womb inside her remained a secret, Scootaloo would thrust his penis into Sweetie with gusto. There wasn’t even a trace of restraint on Scootaloo’s girlish muzzle as he laid his hooves on Sweetie’s chest, and kneeled between her legs, thrusting his penis as fast as his hips could do it. Just like when he put a foal in her belly.

She couldn’t even imagine how hard it had been for Scootaloo to pull out of her to ejaculate all those times, when he just wanted to be in there doing it. He’d lasted a long time, but eventually Sweetie’s softness was just too much of a temptation for him. The sheer gratitude on Scootaloo’s face was breathtaking, when Sweetie Belle in her ignorance let him keep putting seed inside her. He was so excited about ejaculating inside Sweetie, there wasn’t much else that even compared. Scootaloo tried to explain what it was like, and it did sound really, really cool, but really Sweetie was just content with the knowledge that her insides were a haven to him. She had a place that made him feel extra special when he was squirting stuff out, that made her feel extra special, so she always had something to give him whenever he needed it.

She wasn’t so content with having to be a mommy, though. And Sweetie didn’t blame Scootaloo one bit, but she maybe wasn’t the happiest about the situation she’d been roped into by their tricky bottom parts. That’s sort of why she waited until he was inside her to tell him. She should have told him when she saw him, not done... this with him. She felt really... naughty in doing this. Scootaloo couldn’t do any more harm, that’s for sure, but Sweetie knew she was just going to blow his mind when she told him. He was all worked up and she knew his penis tingled like her place tingled, and then she’d tell him and he’d have to face the reality of it all at once. And then... if Scootaloo really liked her, he would... still put his seed inside, even if it made her pregnant. She wanted to know if he’d really do it to her, not just leave her to her own mess, but it surely wouldn’t hurt to wait until she’d orgasmed at least once, and he’d swollen inside her, making it that much harder for Scootaloo to stop himself.

Sweetie’s soft cries rose in pitch at what Scootaloo was doing to her, and with a guilty relief, she felt herself rushing over the cliff of orgasm. Her legs clamped around his, and her insides clamped even more, and Scootaloo bucked against her as Sweetie moaned out, that inner caress she had to do over and over again filling her with stars and making her lose herself in shaking. Scootaloo had gotten so good at this, it was just impossible for Sweetie not to orgasm first. He just gave a shaky smile as her cries peaked and she started helplessly convulsing beneath him. She just looked up at him with adoring eyes while he nestled his stiff shaft in the storm that was happening deep within Sweetie Belle’s hips. He didn’t even thrust, just stroked her to climax and sat there enjoying the feel of it, the feel of what she had to do around him. It made Sweetie feel so used, yet so... useful!

It was like Sweetie was floating on an ocean of pleasure as her squeezes relaxed, that was ever so slowly draining. That was when Scootaloo kissed her again. Sweetie usually took the initiative in kissing Scootaloo, but like this, she just had to sit there and take whatever he was going to give her. If he was going to kiss her, or if he was going to put his penis in her, or if he was going to put a foal inside her, it didn’t matter, because all she could think about was the pleasure, and his presence.

Kissing pulled her out of her daze, and Sweetie moaned eagerly as his lips pressed against hers, arching up as his hips flexed against hers, and inside was that delicious slide, slide, slide that she knew was him. Her legs wrapped firmly around him as his penis filled her, and the kissing took her breath away. Her nose was full of his scent, and her inside place was full of his engorged phallus.

Scootaloo swelled up, Sweetie had quickly learned. That was a thing his penis did. Ballooned up right inside her, and that was a sign that he too was ready to lose himself and start squirting out seed. Sweetie Belle felt it happen, a hearty moan in her chest as his throbbing length pushed wide every inch of her, with its need to fill her. Scootaloo’s thrusting was growing erratic with his penis like that inside her, and his breath was catching. She didn’t have much time left. She had to tell him! Sweetie huffed with the heavy plowing and lifted a hoof to touch his chest. “Scootaloo,” she said urgently. “N-need to... tell you something!” It almost seemed like Scootaloo wouldn’t even hear her, so lost in his animal passions. But he just hunched over her, deep inside, and took a few long hot breaths.

“S-sweetie?” he said almost plantively, his turgidity ebbing within her as he did so. “S-sure, what do you... you can tell me anything Sweetie.”

Sweetie bit her lip to hold back a dizzy, cagey grin, and whispered out, “Scootaloo, do you know where foals come from?”

“Um... a mommy’s belly?” Scootaloo said uncertainly. “I–I think?” His hips were shivering against Sweetie Belle, so eager to finish the job that Sweetie had encouraged him to start. He held still though, for her.

“You can go ahead,” Sweetie said, giving him an encouraging squeeze from within. “Just listen while I tell you,” she added breathlessly. Scootaloo started thrusting again, slowly and gently. But he wasn’t doing it so he could last longer. He was doing it that way so she could keep her wits enough to tell him. Holding out as hard as he could, with his nerves just on fire. Sweetie wasn’t going to make him hold out any more, not this beautiful colt friend of hers, who was stretching her insides so luxuriously. Not with the exciting tingle of a hard orgasm still spinning dizzily up from her loins.

“Any filly can be a mommy,” Sweetie Belle said quickly, just about writhing in the conflictingly fluttery feelings this was giving her. “W-when fillies go into estrus, like our class did, they make an egg~ and if it... it gets fertile... then it becomes a foal, and grows in her until her belly is swollen, and she has to give birth and be a mother.

“Any filly,” Sweetie Belle whispered huskily, tilting her hungry hips into his, “E-even ...me...”

“Sweetie, you’re... you’re...?” Scootaloo managed to gasp out, swallowing dryly and trying to keep thrusting slow enough for her to speak. He was about to go off. Sweetie knew that fire in the back of his eyes, that teeny bit of fear back there, as he lost control of his body. She had to make this quick.

“Your white seed... the stuff your p-penis makes, it’s the seed that fertilizes my egg,” Sweetie gasped out, squeezing her legs around his flexing hips. “Tha-hat’s why there is a mommy and a daddy because... if you put your penis in a filly and... and put the white stuff in her... you’ll make her a mommy, and you’ll~”

Scootaloo actually stopped then, staring at Sweetie Belle in shock. This desperately horny unicorn filly he had been fucking came to realize, sadly, that Scootaloo wasn’t going do it after all. But Sweetie Belle had Rarity to rely on at least, and... and she had that dildo. She had that dildo, that wouldn’t... be... him. And they could still be friends, even when Sweetie was... all swollen up with foal, and Scootaloo resented her for being so foolish. But she had to tell him.

“Scootaloo, if you let your penis... do that in me, you’ll make me a ...mommy,” Sweetie told him, trying not to let the sorrow well up, as she admitted what would make him stop doing this to her. “A-and you’ll be the daddy. Just start s-squirting in there, and it’s too late. I can’t stop it then, until our foal has grown.”

“Sweetie I can’t... do that to you!” Scootaloo gasped, “Y-you can’t be a... I don’t—I don’t want to pull out...”

Sweetie’s heart leapt. She leaned up to her lover and whispered, “So don’t pull out, then.”

“But it’s not f-fair,” Scootaloo bit out bitterly. “You... we’re just playing! I’m not m-making you pregnant. It’s too hard!” He throbbed inside her.

“It’s easy!” Sweetie claimed coyly, as casual as if he wasn’t blowing her mind from currently burying his cock in her. She traced a hoof delicately on his pumpkin orange chest, saying teasingly, “Just let your white stuff squirt in there, and I’ll be pregnant!”

“Hard for you though!” Scootaloo begged, half sliding out of her. “I can’t hurt you!”

Sweetie’s frustrated moan broke any casual demeanor she might have had. This wasn’t going how Sweetie expected it. Scootaloo really would have been... careful, for Sweetie’s sake? It’s like her friend didn’t even care that he would get roped into it too! It was so unfair. Why was it too late already! Why was Scootaloo so...good to her? But—Sweetie had to. She had to see him do it. She needed him so bad!

“Maybe I want it,” she lied desperately. Or did she? Sweetie just didn’t know anymore. “Maybe it won’t hurt me, but what about you?” she asked, heavily stroking Scootaloo’s slim chest now. “Can you do it? Y-you know it’ll make a foal in me, so could you really even... could you still do it? Make me a m...mommy? Y-you don’t...” She lost his gaze, her eyes turning aside, murmuring, “You don’t have to let it start squirting in there...” Sweetie sighed inwardly, feeling like she was losing her friend, who was just such an angel. Scootaloo didn’t deserve to be saddled with her problems if he wouldn’t even do it.

Sweetie gave a strangled yelp as Scootaloo jammed his penis into her, and almost fell against her, pushing off Sweetie Belle’s own huffing chest, to thrust into her wildly. Sweetie cried out in shocked passion, and her own hips just about bucked up against his. That thrusting so closely denied to her, suddenly it was filling her and filling her. She needed it... she needed it so bad, maybe even more than he did! “S-scootaloo~” she whimpered hugging him like an oasis in the desert.

“I can’t—” he gasped, thrust, thrust, thrusting. “I can’t stop it!” he practically screamed. “I-it’s going to come out!”

“It’s okay, Scootaloo,” Sweetie whispered to him, “Just let it happen...” somehow finding serenity in this hurricane of passion. Her insides were going to do it. He was going to do it!

“I can’t—gonna... it’s gonna... n-no I I’m gunna—foal in— our f—gck,” Scootaloo could barely speak. His compulsive thrusts shuddered as his penis throbbed inside her, and then staring at Sweetie with such a look of desperate need, Scootaloo just jammed up against her, not pulling out of her, but going all the way inside her. And then Sweetie felt that familiar thrashing in her inside place. “Sweetie, he—help—hahhh!!” he stuttered, as something practically jetted against her in there. He almost seemed to hold it then, but then with a tense grunt another pulse came out of his thick rod, and then another, and then he was just sinking against Sweetie’s hips, his penis steadily pumping inside her.

Sweetie Belle gazed up at him, and felt such affection for Scootaloo. Who knows what he felt, with every squirt that he didn’t want to do, yet he did, and then he did again and again. She reached a hoof up to just stroke his cheek, as Scootaloo lustfully ejaculated inside her, thick pulses of warmth spreading in her with every wanton spasm of his rod.

I feel like I got too elaborate with that last scene.
