Prologue: A Lesson in Carnality

“Ah hate this…” Apple Bloom huffed, wincing with each step as she walked, her yellow coat glistening with her sweat despite the mild weather. It was a lovely spring day in Ponyville, not long after the Winter Wrap Up of that year. Flowers were blooming, the plants were all green and growing healthily. Birds flitted through the slightly-cloudy blue sky, and even more were nesting up in the trees, with many of those nests filled with eggs given the season. The streets were mostly empty save a few stragglers, as they always were this time of year, and the usually bustling village was like a ghost town instead.

“You girls think zomponies got everypony?” Scootaloo asked in a pseudo-scared tone, working to keep their moods light despite her own discomfort, flicking her tail in annoyance at the irritating feelings within her.

“Z-zompon~ies?!” Sweetie Belle squeaked, her voice cracking. She looked around nervously, before glaring softly at Scootaloo, who was barely holding back a laugh, “Oh come o~n Scoots…I don’t really want to mess around like that right now.”

“Every time ponies aren’t around in town you fall for that,” Scootaloo teased, giving another soft flick of her tail, letting it playfully slap against Sweetie’s rump…and causing a soft squeal from Sweetie as she stopped dead, legs locked and shivering in place, her tightly curled two-toned pink and purple tail flagging aside.

“Ohmigosh, are you OK?!” Scootaloo asked, feeling guilty despite her innocent intentions, “I was just trying to lighten the mood…”

“I’m…OK, it’s just…don’t do that again, OK?” Sweetie said as she recovered a moment later, forcing her tail back down, before nuzzling into the side of Button Mash, the young colt beside her.

“OK, I won’t, I promise,” Scootaloo said, her fuzzy orange ears folding back, “I didn’t know you were that sensitive.”

“It’s alright Sweetie, we’re almost there.” Button Mash comforted verbally, though despite walking right beside her, he didn’t dare to touch Sweetie after the reaction that that soft brush of Scootaloo's tail on her rump had gotten from her. Instead, he let the muzzle of the snow-white filly nuzzle into his own coat of dark amber-brown.

“Look,” Rumble called out, pointing a slate-gray hoof to the giant cupcake that came into view. Said cupcake was atop the tower of a building that all of the ponies, and especially foals, in town knew quite well, with the rest of the building soon coming into view. The wider building looked like it was made of gingerbread, candies, and other sweets, foretelling the sweet treats that awaited ponies inside if they had the spare bits for them. “We’re here. Then we can find out what…”

Scootaloo shushed him by flailing a forehoof in front of his face, seeing a pony nearby. “Why don’t you just get a megaphone and announce it to everypony that we're…” she huffed, before sighing, “...sorry, I just…we should go. Let’s get there, learn what we need to, then possibly…take care of ‘it’.”

“Yeah, probably for the best,” Rumble replied, giving Scoots a bashful smile. He couldn’t really blame her outburst, given the circumstances. “I don’t want you to go through this any longer than you have to.”

“Speaking of, how’re you holding up, AB?” Tender Taps asked, with the tangerine-orange colt trotting beside Apple Bloom.

“Could be better…much better. Le’s just get in there ‘n’ find out, then maybe…like Scootaloo said, maybe we can take care of this after.” Apple Bloom replied, her cherry-red mane matted to her forehead with sweat, getting a nod from her beau.

Soon enough, they arrived at Sugarcube Corner, the scent of sweet baked goods wafting from the building awakening another kind of hunger in the foals than the one they all already collectively held, but didn’t really understand. They entered and were greeted with what they expected: Rainbow Dash had earlier told Scootaloo that her, Pinkie Pie, Rarity, Applejack, Twilight Sparkle, and Fluttershy would be meeting up here, and the group of foals were happy to see they were, indeed, all there.

Looking over, Rainbow smiled, before walking over and tussling the dark-cerise-pink mane of the filly whom she viewed as her little sister. “Heya Squirt, just in time. We were about to shut the doors and help Pinkie close up for the day.”

“But it’s only four o’ clock? Isn’t Sugarcube Corner usually open until eight?” Rumble asked.

“Nopie-dopie, those are our winter and ‘off-season’ hours! We’ve got special hours for parts of Spring, Summer, and some of Fall, which are happening now!” Pinkie, who had popped up behind the foals out of nowhere and startled them, exclaimed with the usual inordinate exuberance that all but defined her, “We were just about to have a private party of sorts, and I guess we can invite you too, since…” Pinkie paused, then smelled the air around the fillies, making them shy away a little from the unexpected action, and with all the foals just attributing that to Pinkie Pie being…Pinkie Pie, “...you’ve got your cutie marks, and you certainly smell like you’re old enough!”

“What do you mean by that, Pinkie? We came over here because we’re all feeling kind-of…weird today, and Sweetie feeling weird is making me feel kinda…weird too?” Button Mash tried to explain, quite confused by the whole situation and not sure how to convey it aloud, “I mean, I couldn’t even focus on my video games; I just wanted to be around Sweetie all the time, and that’s…so weird for me!”

“Yeah, Apple Bloom and I were trying to practice a new dance move, but when I was supposed to grab her around her waist from behind and swing her, I just kinda…” Tender said, before trailing off, a blush growing on his orange cheeks.

“Rumble was flying with me, then he said he ‘smelled something really nice’. Before I knew it, we had landed on a cloud, and he was trying to stick his muzzle…somewhere he wasn’t supposed to…” Scootaloo said, giving Rumble a soft glare, which he bashfully looked away from, a light pink forming on his slate-gray cheeks.

“Ah…I do believe I know what’s going on here,” Rarity said, giving a sly little smile, only confusing the foals more, “Scootaloo, I’m surprised your aunties didn’t notice, and Apple Bloom, surely your...siblings Applejack or Big Mac have told you about being…‘in-season’?

“‘In-season’? Ya mean that it's Spring?” Apple Bloom asked, clearly baffled by the term.

“Now hold on a dang minute Rares, ya should know as well as Ah do that these six were havin’ a sleepover last night. Must’ve snuck up on ‘em overnight. Guess Ah shoulda known it’d happen soon, given how grown up these three've been gettin',” Applejack countered, getting a nod from the three fillies in nearly unison, before gently ruffling Apple Bloom’s mane affectionately, "'Specially you, AB. Growin' like a weed, bigger by th' day. Even got yer cutie mark...” Apple Bloom just beamed happily at the acknowledgement.

“Yeah, I’m pretty sure we all started feeling like this this morning, and it’s only getting wo~rse!” Sweetie exclaimed with a voice break, before looking to Rarity, “What’s going o~n? Why do we fillies feel all extra-sensitive, and why are our legs locking up and our tails lifting up all the time, and why are the colt all so interested in…what’s under our tails…now?”

“Why do Ah have ta pee all the time? An’ Ah can never even empty mah bladder all th’ way, jus a little here 'n' there…an’ th’ smell…!” Apple Bloom asked, waving a forehoof in front of her nose emphatically, before she clammed up some as she realized what she’d just blurted out, with Sweetie’s question opening the floodgate of unbridled foalish curiosity.

“And why are my filly-parts all…tingly and itchy and…why do I feel so hot all the time, especially in my lower tummy and under my tail?” Scootaloo asked, and even then her tail was partially flagged and swishing. All three fillies looked like they shared the same questions as their companions', seeming to look expectantly at the older mares for answers to all their questions all at once.

The six mares looked at each other, then the other five focused their gaze on Twilight. “What, me? You want me to tell them?” Twilight asked, clearly surprised.

“Well, I’m sure you know more about the subject than any of us, with as many ‘biology books’ as you’ve read,” Rainbow said, and, while the implications were lost on the fillies and colts, the other four mares chuckled lightly.

“I read those books for perfectly valid socio-biological research, I’ll have you know!” Twilight countered, just getting a shit-eating grin from Rainbow, and a plaintive look from Rarity and Applejack, “Fiiiine. So you two don't have to.” She then charged her horn with magic, mentally focusing on something in the distance, before suddenly a book popped into her violet telekinetic grasp. “So, what do you fillies already know about sex, or how foals are made?”

“Sex? How foals’re made? Huh?” Apple Bloom asked, clearly confused, the other two fillies sharing the same sentiments, made obvious by the expression on their faces, with that alone quite answering the mare’s question.

“So…I’m going to take that as ‘nothing’.” Twilight assumed, giving a soft chuckle.

“Ah knew Ah should’ve taught ya earlier, but Granny jus' insisted we wait 'til yer first heat…” Applejack said, exasperated, shaking her head softly. “...lotta good that strategy turned out fer me…”

“What’s ‘heat’?” Apple Bloom asked, “Are we feelin’ this way cuz it’s a mite warm outside? Ah never felt like this when it was warm out before, or even when it was hot out!” she continued, grunting in frustration.

“Could you please just tell us what’s going on with us already? I mean, I heard from Tootsie Flute at school that foals are made from having something called 'sex', and that you need a stallion and a mare, or an older filly and colt, to make a foal, but I don’t know anything else other than that,” Scootaloo finally stated bluntly, looking at Twilight. In her arcane grasp, she noticed just what the book was titled: ‘A Filly’s First Estrus: How to Tell Your Foal What's What, and Basic Sexual Education. By Bundle Joy'. “‘Estrus’? ‘Sexual Education’?”

“OK, well,” Twilight said, opening the book to the table of contents, then flipping to the proper section, “What you are experiencing right now is called ‘estrus’, or more commonly known as being ‘in heat’ or ‘in season’, which often happens to a filly or mare during mating seasons, also known as breeding seasons, after she reaches a certain level of maturity. Mating seasons are the only times of year, naturally at least, for the ponies to successfully breed and bring new foals into the world. Most ponies go into heat monthly during the warmer seasons, namely spring, especially summer, and during the warmer parts of fall. The more a mare is in the sun when it's stronger during these times, the more her body produces the hormone that makes her go into estrus, and generally the stronger the estrus will be.”

“Yeah trust me, that’s true. Mah heats’re just plain awful, given Ah’m outside all the time, and Ah’m an earth pony.” Applejack said, sighing softly and squirming a bit.

“Wait, why does bein’ an earth pony matter?” Apple Bloom asked, before getting a soft smile from her big sis.

“Well, Ah’ll tell ya the whole story later, but in a nutshell, the whole earth pony tribe was near extinction cuz of low fertility, unable t’ make more foals cuz earth ponies jus’ couldn’t get pregnant or make others pregnant, an’ were too proud t' interbreed with their then-enemies the pegasi or unicorns. So when only about one thousand of our kind were left, th’ Tree a Harmony took action and supercharged our virility an’ fertility…and our sex drives. Solved th' near-extinction problem right quick, but left us with th' stronger breedin’ instincts from that generation on; real strong heats an’ a higher possibility of twins fer mares, an’ stallions havin’ high sperm counts an' huge loads as a result.” Applejack explained, getting a glum look from Apple Bloom, even if half of what she’d said went right over her head; all she’d needed to hear was that her heat was worse because of the tribe she was born as.

“That sucks! Ah wish Ah weren’t an earth pony nomore, if Ah gotta deal with this every month now!” Apple Bloom lamented, looking miserable at having to cope with this for the rest of her life, as far as she knew.

“Aw, don’t feel bad! As long as ya know how to deal with it the right way, and safely, being in heat can be totally fun!” Pinkie butted in, slightly bouncing in place as she spoke, as she was wont to do.

“Ah dunno how feelin’ like this can be fun!” Apple Bloom said, growling slightly in anger at her uncomfortable situation.

“Well, engaging in penetrative intercourse will stimulate a mare much more while in estrus than when they’re not, due in part to the higher receptivity, and tightness due to vasoconstriction, of a mare’s vaginal canal to a stallion’s phallus, and higher lubrication production, in mares, the effect of a mare’s estrous pheromones on a stallion’s seminal fluid and spermatozoa production increasing their semen volume upon ejaculation, as well as an increase in general sensitivity to touch - especially around the genitals, due to increased blood flow there for both genders during the breeding season as well, though even more so for mares!” Twilight breathlessly lectured, before feeling her cheeks flush as she realized the confused looks she was getting from around the room, though especially from the foals she was trying to explain all of this to.

“OK, can somepony please repeat that again, in Ponish now?” Sweetie asked, getting similar sentiments from everypony else present.

“I think she’s trying to say that the extra sensitivity, tension, and wetness you’re feeling down there only makes sex feel that much better, darling Sweetie, for both stallions and mares,” Rarity said, giving a soft smile, “and I believe she does have a good point there.”

“Ok, but what is sex?” Button Mash asked, getting impatient.

“Oh, right,” Twilight said, before looking back to the book, “Well, there are many different ways to have sex, including oral, anal-”

“Ew! You mean…sex involves your…tailhole!?” Sweetie asked, aghast, and Twilight would swear Sweetie would have gone pale if her coat weren’t already white.

“Well, while you can use your…anus, most ponies prefer to engage in either oral or-”

“OH FOR…! Cut to the only part that matters right now! The only thing that really helps a mare or filly in heat! Tell ‘em how to ease that burn in their bellies the right way, not the other not helpful distractions.” Rainbow cut in, getting a disgruntled look from Twilight.

“If you ponies would just let me talk…” Twilight huffed, before flipping another couple pages, “...fine.”

“And give them the abridged edition. I’m sure they can figure out the rest on their own,” Pinkie added, ”After all, exploring a pony of the other gender - or even your own gender! - for the first time is part of the fun!”

“OK, OK!” Twilight said, clearly getting frustrated by the constant interruptions, before looking over at the other mares, “Anything else?”

Silence.

“OK good,” Twilight said, before clearing her throat. “Now, as I’m sure you know, when a stallion and mare love each other very much, they do something together that makes a foal, right?”

The sextet of foals nodded. Pretty much every foal was told that when they were younger and asked why their mother was pregnant, they had a new baby brother or sister, or where foals come from in general, after all.

“Well that 'something' is called sex, short for sexual intercourse, also known as mating or breeding, or more informally as making love—” Twilight started.

“And rutting, banging, and FUCKING!” Came a particularly energetic exclamation from a particular pink pony.

“—yes, it’s called those too…” Twilight begrudgingly admitted, giving a soft glare at her newest interruptor, before getting back to her lesson, “...though sex isn’t only used for making new foals, even if that is its natural purpose. It can also be used to feel closer to somepony you love - usually to reinforce a bond with your special somepony - or simply to relieve your biological urges, which are often brought on by estrus, though not exclusively. Sometimes, especially during puberty, you just want to have sex because you want to. Or because it's been a while since you have had it. Or simply because having sex feels really, really good!”

“So that’s all good and all, but what IS sex?” Rumble asked, his foalish curiosity clearly gnawing at him more as his sought-after answer was prolonged.

“Oh. Right. Well, to put it simply,” Twilight said, consulting the book, “‘Vaginal sexual intercourse occurs when a male’s penis—

“COCK, DICK, FUCK-STICK!”

“—when a male’s penis is introduced into a female’s vagina’. Or, in other words, when a colthood or stallionhood - or cock, as Pinkie so ineloquently called it - penetrates into a marehood or fillyhood. The penis is usually kept safe inside of the prepuce, also known as a sheath, and often only comes out when urinating or for sexual reasons, or when the male is really relaxed or even sleeping. There is also the scrotum behind the sheath, a sac which houses the two testes, or testicles—”

“BALLS, NUTS, FOAL FACTORIES!”

“—which both produce a gamete cell called sperm when a colt reaches a certain age, called puberty, which is usually around twelve to fourteen years old in colts. There are also several accessory glands, especially the prostate, which together produce a gooey substance called semen, which nourishes and protects the sperm, and carries them deeper into a mare's reproductive tract where they’re naturally meant to go.”

“Oh, so that’s what those things are for…” Button said, looking between his hind legs at the dangling brown sack there with its two egg-shaped contents, “...always wondered why they were there.”

“Th’ penis goes into…but there ain’t nothin’ down there but where Ah pee from, an’ that’s way too small fer anythin' to go into!” Apple Bloom exclaimed, aghast.

“Well, yes, between the vulva - that’s the outside of your fillyhood, the ‘lips’ there - there is the urethra, where urine comes from and where you’re referring to, but there's also something else: the vagina—”

“PUSSY! FOAL-TUNNEL! HONEYPOT! LOVE-CANAL! COCK-WARMER!”

“—also commonly known as a ‘pussy’, yes, or fillyhood or marehood,” Twilight said dryly, glaring at Pinkie again after her umpteenth outburst, “which is where a colt or stallion’s penis will go into and mostly remain during vaginal intercourse. At the end of the vagina is a sphincter of sorts called the cervix, which leads to the uterus, the organ where a foal is held during a pregnancy - we'll get to that,” Twilight said as Button raised a hoof, as if he were in class, “and above that are the very thin fallopian tubes and the ovaries. The ovaries produce the other gamete cell, called an ovum - or more commonly called an egg, after fillies enter puberty - which usually starts earlier in fillies, around eight to twelve - during estrus, which then passes through the fallopian tubes after the egg is released in a process called ‘ovulation’, and finally will eventually end up in the uterus.”

“Ya mean a colt puts his willy in mah hoo-ha, an’ we’re havin’ sex?” Apple Bloom asked, getting a nod from Twilight.

“But…doesn’t that hurt the fillies or mares, if a…a pe-nis were to get pushed inside of them between their legs?” Rumble asked, looking a bit concerned.

“Well, if it’s their first time, and they’re not sufficiently lubricated, a thin protective membrane called a ‘hymen’ may be torn and cause some minor pain and bleeding.”

“Uh…we could bleed down there?” Scootaloo asked, clearly uncomfortable at the idea.

“Well, yes, but only a little bit, and only during the very first penetration. It’s usually nothing to be concerned about, and sometimes won't even occur at all if sufficiently aroused and lubricated. Also, if you do a lot of physical activities, especially athletics or stretching, sometimes it will simply tear all by itself. So, it may be something you girls may not even need to be concerned about at all, especially with you Scootaloo.”

“Oh…” Scootaloo said, looking a little uneasy at being singled out like that. She didn’t do THAT much stretching or exercise, she thought, did she?

“There’s also the possibility that being penetrated at all, though especially during the first time, may cause some slight discomfort as the vaginal walls are spread apart, especially if the penis is particularly large or the female particularly small in comparison, or if the penetration was very sudden. But, if the filly or mare are in estrus during sex, it’s unlikely to be uncomfortable, since their vagina is never more ready to receive a penis than then. At the very least, out of estrus, they should be completely aroused and well lubricated for the stallion to enter them comfortably. Oral sex or other foreplay usually helps out with that.”

Seemingly content with the answer, if a bit confused about what ‘foreplay’ and ‘aroused’ meant, let alone what ‘oral sex’ was, the foals waited for Twilight to continue.

“So, the most common method of intercourse starts when a stallion mounts a mare,” Twilight said, before levitating the book around for the foals to look at, the page containing an illustration of a stallion mounted atop a standing mare in the book in traditional ponystyle.

“Hey, that’s what ya did t’ me when we were dancin’ earlier, climbin' all up on mah back from behind like that!” Apple Bloom exclaimed, looking to Tender Taps.

“Well, it felt right to do, what with your tail being aside and your…your pussy doing that…thing it was doing!” Tender countered, clearly quite uncomfortable at his fillyfriend’s outburst.

Twilight groaned softly as Tender said ‘pussy’. Leave it to Pinkie to teach them such crass words, when the scientific terms worked just fine. “So, that ‘thing’ Apple Bloom’s vulva was likely doing is called ‘vulvar winking’, and it, along with flagging her tail, is instinctively used to entice a stallion and show him that the mare doing it is ready to mate with him, as well as help to spread her natural lubrication, and expose her more lubricated vaginal entrance to make the penetration easier by giving the stallion an easier, slippier target."

"Mares in heat usually just do both on reflex around stallions or colts while in estrus, so it’s not always a direct invitation for sex. That brings up one of the most important things about sex: ALWAYS make sure the other pony wants to have sex with you. Don’t just presume they do just because of what their body’s doing, or how they’re acting, or how good their filly or colt parts smellThis is called 'getting consent'. ALWAYS ask ponies first, before doing anything sexual towards them, and that especially includes mounting them. Fillies, the same goes for you: just because a colt or stallion unsheathes or gets an erection—”

“A boner! A hard-on! A chubby! A schlong! A steel beam! A jizz-cannon! A foal-maker!”

“Pinkie, dear, would you please stop interrupting. Twilight is liable to blow a gasket eventually if you keep doing it,” Rarity softly warned the other pony as she saw Twilight getting more and more agitated with each disruption of her lesson.

“A fuck-stick! A cum-squirter! A stallion-sauce-shooter! A—aw, OK…”

“Ahem…like I was saying, just because a colt or stallion gets an erection doesn’t always mean he will want to have sex with you, just that he may be reacting subconsciously to your estrous scent. So yeah, remember: ALWAYS ask.” Twilight said, before getting back to the lesson. “So, after the male mounts the female, he will generally insert his erect penis into her vagina.” Twilight showed the foals another diagram with the mare and stallion’s hips meeting, this one involving a separate cutaway of the stallion’s penis inside of the mare’s vagina, getting some blushes from the foals.

“How, um, how and why does a penis get erect?” Rumble asked, though his expression showed he may know what she meant by ‘an erection’.

“Well, how is simple really: blood flows into specialized chambers of the penis upon certain stimuli, causing it to swell and thicken, getting the male’s penis firm and able to effectively penetrate a mare’s vulva, thus making him ready for mating. The scent of a mare or filly’s pheromones - which are certain scents a mare or stallion make when fertile, or even aroused, to attract a mate - the sight of a mare’s vulva or ‘winking’, seeing other ponies having sex, a promise of having sex itself, or even simply rubbing the sheath or testes, will oftentimes do the trick, among a myriad of other stimuli,” Twilight replied, before continuing.

“Anyways, after the mare is penetrated, the stallion will move his hips back and forth, moving his penis in and out of her vaginal canal to stimulate them both, until orgasm is reached by him, which is vital to having a foal. Mares can also have orgasms, with enough stimulation of her genitals and especially clitoris, and while they’re not essential to conception, meaning the making of a foal, the vaginal and uterine contractions caused by them not only help the sperm reach the egg, they also feel really darn good too, just like his!”

“So how does a foal get made? With the sperm and eggs you mentioned earlier?” Sweetie asked.

“Very astute, Sweetie! That’s right: an of-age colt or stallion’s orgasm will ejaculate about a full two hundred and fifty milliliters, or about eight or so ounces, often less though occasionally more, of what helps make the foal - semen, containing billions of the sperm cells I mentioned earlier - deep into a mare's vaginal tract, or possibly even uterus, with force via involuntary pelvic muscular contractions. I should mention that any semen that gets on or near a mare’s vulva while she’s in heat could possibly get her pregnant if she’s not using protection!”

"What happens next?" Sweetie asked, clearly enthralled with learning about what could give her a foal one day.

“So, after the stallion puts his semen into her, the sperms then move towards the mare’s egg over the next four to six hours generally, and one single sperm will penetrate its outer membrane and join together with it. Each sperm contains half of the stallion’s genes, and each egg half of the mare’s genes, and they will basically then merge and create a random full set of genes, a single cell called a zygote; what will become a foal. After that, if all goes well, the zygote will attach to her uterine wall within three weeks of conception - when the mare will officially be considered pregnant - and will carry the foal in her uterus for anywhere from eleven to twelve months, but about eleven and a half on average, her body keeping it nourished and healthy by sharing her nutrients with it through her blood flow, and then give birth to it when the time comes.”

The foals had a varying degree of reactions to that information, from Sweetie looking delighted at the thought of having a cute little foal of her own, Apple Bloom seeming mostly positive, to Scootaloo, who seemed almost repulsed at the thought of motherhood, and all three colts were clearly nervous at the thought of being a father.

“That bein’ said, as important as it is to know how to have foals, it’s also jus’ as important t’ know how to not have foals, iffin’ yer not ready for 'em. Taking care’a foals is a lotta work, an’ expensive, so ya should only have foals if ya know fer sure yer ready to care for them until they’re all grown up and old enough t’ care for themselves. So, ‘bout eighteen years or so. Not to mention that ya should probably be special someponies with, or better yet married to, th’ stallion who gives ya said foals, an’ he should help with raisin’ them too.” Applejack said, getting an agreeing nod from all the other mares.

“That’s right, AJ. Now, there are numerous ways to prevent pregnancy, though the most common ones are either simply not having sex with a colt or stallion during estrus at all - though that’s easier said than done - or potions containing certain herbs, or the herbs themselves, either chewed and swallowed, or brewed into something called 'moon tea'. There are also condoms, which are a physical barrier that prevents semen from getting into a mare, but those aren’t often used since the semen is what cools a female’s estrus. These methods are the most popular among earth ponies, pegasi, zebras, or other non-magic-casting species. If you happen to know, or be, a unicorn, or know an alicorn even, and are comfortable asking them for such, you can just ask them to cast a simple spell on you to prevent pregnancy. Or to teach you it, if you’re a unicorn yourself,” Twilight explained, looking to Sweetie and the unicorn horn upon her head, “Speaking of…I should probably cast that for you, since I’m certain you’re not ready for foals yet.”

All foals gave some variation of ‘yes’, and Twilight then looked to Applejack and Rarity, and, getting a nod from each, lit her horn. Each of the foals felt a mild tingling in their lower bellies for the fillies, and in their balls for the colts, leaving them a little confused. “...there," Twilight looked to the fillies, "You’re now safe from getting pregnant, since you can't ovulate,” then looked to the colts, “or getting anypony else pregnant, as you can't produce sperm, for the next six months, in case you all choose to put the lessons here into…practical application. Scootaloo, boys, I’m sure your guardians won’t mind the precautions. They were adolescents once too, and know what going through their first mating season was like.”

None of the foals seemed to have any objections to being temporarily made infertile. None of them were really ready to have foals, after all, with them just barely not being foals themselves at that point.

“Boy, Ah remember when Ah was just havin’ mah first estrus…didn’t know what was goin’ on either. Thank goodness Big Mac an’ Braeburn were there t’ teach me.” Applejack commented, her eyes lidding, seemingly at the memory.

“Ya learned about sex from bro, an’ Cousin Braeburn? How’d that happen?” Apple Bloom asked, cocking her head.

“Well, if ya really wanna hear about that…”

“Yeah, sure!” came a trio of fillies’ voices, and an agreeing look from their male peers.

“Alright, so, it started on a spring day, not unlike this one…”

Author's Note

And so it begins...

Chapter One: An Apple’s Blossoming

Applejack groaned, already winded after she only planted the third row of vegetable plants today. She’d been feeling a bit more tired than usual since this morning, her thoughts foggy, as though her brain thought there was something far more important for her to be focusing on than whatever she was doing then. Under her tail was burning and ached to be touched, but she’d quickly found out through experimentation that her own hoof never felt…quite right; like that’s not what her body wanted, not at all. She’d heard estrus being mentioned before by fillies at school - how mares went ‘in heat’ during the breeding seasons and got all slick and needy and itchy in her mare-parts. Something about mares in heat wanting a stallion, and wanting to make a foal with them. How to make a foal, though, they didn’t mention, so she had no clue, beyond her needing a stallion and her mare-parts to do so.

Panting from the heat of the relatively-mild sun and her abdominal muscles slightly aching already, though decidedly neither were from the light labor she’d done, Applejack figured now would be a good time to take a break. She headed into the farmhouse and poured herself a nice cool glass of water, guzzling it like she’d not drank anything all day, then having a second. She relaxed for a moment, but couldn’t seem to get her tense muscles to relax, especially as her hind legs kept locking up randomly, as though her body was getting ready for…something. Ready for…mating? she wondered, though she didn’t even really know what that meant. Another mystery word from the fillies at school.

“Y’alright?”

Applejack jumped, then turned to the sudden sound of a familiar voice, seeing her cousin Braeburn looking over at her with a concerned look on his face. She saw that, as always, he was a fairly strong-looking colt, his coat a vivid yellow and his mane a mid-brown. As she looked down to his stifle, seeing it adorned with a single red apple, she remembered that he had just recently gotten his cutie mark too during his visit here, which had been a time of great excitement for him. They'd even thrown him a little party for getting it.

“Yeah, Ah’m good…” Applejack said, still finding it pretty easy to casually lie, especially about something as embarrassing as having the physical endurance of a young foal right then. She was an earth pony for peat’s sake, famed for their vitality and ability to work day and night until a job was done! “...jus’ got thirsty is all.” She waved her spindly adolescent foreleg at him, as if trying to wave away his concern, though she couldn’t hide that her cheeks were flushed, and she was quite sweaty.

“We’ve only been out here about half an hour, an’ you’ve worked up that kinda sweat? Geez, ya must’ve been workin’ real hard!” Braeburn said, though his expression didn’t look convinced of her half-truth, before waving to her, “Alright, well, Ah’ve gotta get back to my own work!”

With that, Braeburn turned and headed back to the door, going outside to where he and Big Mac were tilling the fields she’d be seeding the next day. While he headed away from her, Applejack found herself admiring his fine asscheeks, the firm muscles shifting as he walked. When his tail flicked errantly, her breath caught in her throat. She saw his large balls there in their yellow-coated sack, hanging low from the warm weather, and while it wasn’t an unusual sight - whereas nopony ever really wore clothing outside of special occasions, certain social groups, or for warmth - she felt her legs tremble this time at the sight, and her tail flagged up high on reflex.

Applejack heard a steady drip drip drip coming from behind her and a weird sensation, like her filly parts were rapidly moving, the same sensation she got as she squeezed down while getting the last few drops of urine from her bladder whenever she used the outhouse, but this time all on their own. As she looked between her forelegs behind her and saw a small wet spot in the soil between her hind legs, she almost wondered if she’d just peed right there and then on the path…but that sensation in her bladder of having to go was certainly still there. She groaned softly to herself while she found somewhere to relieve herself for the umpteenth time since she’d woken up.

Finding a tree a good distance from the young stallions working the fields with her, she squatted and let loose her stream. Well, more like a trickle oddly. Just like this morning, she could barely get any pee out. Her nose crinkled up as she could smell the powerful scent emanating from it; it smelled like urine for sure, while smelling like her too obviously, but…she could smell something more too. Something musky and earthy and…kinda sweet? It made her head feel funny, so, after moving her filly parts to get the last bit out, she headed back to work.

The rest of the workday was a struggle for Applejack, having to stop for a drink and get out of the sun several more times. It felt like it was a scorching summer day instead of the mild spring one she knew it was, almost working herself into a lather despite seed planting being very light work. She hadn’t noticed as her tail flagged when she asked the colts working the fields some questions, unconsciously exposing herself to her brother and her cousin. She felt the overwhelming - and wholly unknown to her before then - feminine urge to show off to the colts like that, feeling her filly parts squirming and moving under her tail when she flagged it, though thankfully facing away from them when it had happened.

Finally, the last of the rows in the tilled field Applejack was working in were filled, just as Big Mac and Braeburn were heading in too, looking just as tuckered out as she was from taking turns pulling the plow. She couldn’t wait to get inside and sit down, though with as moist as her fillyhood constantly felt, she wasn’t sure she would be able to sit without putting a towel beneath herself. She didn’t know what it was, but she had felt that slickness pretty much since she’d woken up, as well as noticing she’d emanated this odd sweet, earthy, musky smell too.

“Right, how does a lunch of some veggie sandwiches and some soda, alongside a few hands of poker, sound?” Braeburn asked, getting a loud “eeyup” from Big Mac.

“Ah dunno…Ah never seem t’ have a chance against you two,” Applejack said. As of yet, with her still learning the rules and tricks of poker, she’d never won a single hand against neither Big Mac nor Braeburn.

“Aw, c’mon. Ya can never learn if ya don’t try sis. Maybe, one day, you’ll even be as good as me in poker!” Big Mac boasted, getting a roll of the eyes from his little sister.

“Gee, what an inspiration ya are, bro.” Applejack replied dryly, before sighing.

“Well, it’s not like we’re playing for real bits anyways. You don’t really even have anything to lose…” Braeburn said, before giving a teasing smile, “...that is, unless you want to make things more interesting.”

Applejack, never one to turn down a challenge, snorted. “What’d ya have in mind?” she asked, narrowing her eyes.

“It’s easy. The loser has to do anything the winners say, within reason. Winners are the ones with the most chips after five games. Mac an’ Ah will even play with a disadvantage. Sounds good?”

“Yer on!” Applejack said, though she almost immediately regretted it. She’d never won before, and doubted she would now, but her competitive spirit wouldn’t let her turn the challenge down.

“Alright, have a seat around the dining table. Ah’ll go make the food and drinks. Mac, get the cards and chips set up.” Braeburn said, heading to the kitchen.

That left Applejack and Big Mac alone. AJ could see her brother’s nostrils flared, could hear him sniffing the air as he shuffled the cards and distributed the chips, and she felt self-conscious all of a sudden. Was he…smelling her weird new scent? It was awkward, but thankfully it only took Braeburn a few minutes to get the sandwiches done and pass them around, along with some potato chips and soda.

“Right, so, we’re playing five card draw, jacks or better. So, first, five cards are dealt face down to all players. After the first round of betting, you can choose to trade back up to three cards to get that many new ones from the deck. Same winning card ranks as the last poker we played, except jacks are the lowest high card you can have. Pair beats high card, full house beats two pair, an’ so on. So, after betting again with a 'call' - or you can not add to the pot with a check, or outright give up with a fold - everypony who didn’t fold will show their cards, an’ the pony with the best card combination wins. I’ll deal the first round, then Mac, then you. Remember, the ones with the most chips at the end win.” Braeburn explained, starting to deal the cards.

“Sounds simple. What’s mah advantage?” Applejack asked.

“Ya can exchange all five cards instead of jus’ three, an’ we’ll play all of our cards but the first one face-up, like in stud poker.”

The word ‘stud’ made a shiver go down the young filly’s spine, though she couldn’t remember why. “Right, sounds fair.” Applejack said, before looking at her cards.

As she did, Applejack realized she could smell the colts. Sure, she smelled them all the time, but now, it was all she could focus on. That musky scent of a hard day’s work, their masculine musk wrapping around her brain like never before. She could see their lips moving as she stared blankly at them, a dumb grin on her face as her mind was elsewhere. Then she realized Braeburn was talking to her. “H-huh?” Applejack asked, softly shaking her head to try to lessen the foggy feeling in it. It didn’t help.

“Ah said, ‘put yer big blind bet in’. It's 10 chips,” Braeburn repeated with a slightly irritated tone, indicating the stack of chips next to Applejack.

"Alright, first round of betting." Braeburn announced, adding a five-bit chip to the pot.

“Oh, right,” Applejack said, doing so, then looking at her cards: an ace, two queens, a five, and a three. She threw in her bet. "Call."

Applejack absentmindedly added chips to the pile…but not quite the ones the colts were expecting.

“Um…AJ…the betting chips, not your lunch.”

Applejack looked at the pile and, indeed, saw she had added a hoofful of her chips from her plate into the betting pile. “Ah, right. Ah don’t know where mah brains’ve been t’day,” Applejack said, shaking her head softly, before removing the food from the table and adding the correct chips to the pile, her cheeks flushing slightly at the light chuckles from her brother and cousin.

“Ooo, confident. Call.” Big Mac said, getting back into the game and matching Applejack's bet.

“Call.” Braeburn did too.

“Right, what did you want to exchange?”

Applejack slid her first two cards, the number cards, in. She got back another ace and a two.

“Right, second bets,” Braeburn called, AJ tossing in more chips, Brae matching, while Big Mac folded.

“Now show ‘em!” Braeburn said, putting his own card on the table.

AJ put her own down confidently. Two aces, two queens.

She then looked at Braeburn’s: three jacks.

“Three of a kind trumps two pair,” Braeburn said, then collecting his winnings.

Applejack huffed, before giving in her cards.

Each round AJ lost, both because she got bad cards and didn't even bother looking at her opponents' exposed cards, but also because she was starting to focus less and less on the game, and more on her fellow players. The masculine scent of them, the squareness of their jaws, their musculature earned from a lifetime of farmwork; all things she’d never really noticed before, but now being all she could think of. How attractive her cousin and brother looked to her, how much her pussy was drooling, soaking the chair cushion, and winking as she looked at them. How much she wanted to get closer to them, even if she wasn’t entirely sure why. She was just betting blindly, calling and sliding whatever chips she grabbed randomly into the pot, as if she just wanted to get this over with and get on with something her brain deemed more important. Something with these stallions. Before she knew it, when she reached for more chips, there were none to grab.

“Well, looks like AJ’s outta chips, an’ lost.” Big Mac said, giving a smirk, before folding his cards. Looking over at the huge stack of chips in front of Braeburn, it was obvious who the top winner was.

“Right, so, since Ah have the most chips, Ah get to give her first command,” Braeburn said, giving a smirk as Applejack simply stared at him with a dreamy expression, clearly spacing out. Braeburn knew exactly why she was spacing out, able to smell the intensity of her estrous scent, and headed over to the living room. He grabbed out a small paper shopping bag, before reaching his muzzle into it and pulling out…a pair of panties. White, lacy panties, complete with a pair of equally lacy, stifle-high socks he soon pulled from the bag as well. “And that’s for AJ to wear these, then turn around with her rump towards us and her tail flagged up.”

Applejack blanched as she saw the girly clothing she was meant to wear, looking at Braeburn in disbelief. “Ya bought those cuz ya knew Ah’d accept yer challenge, then lose…” AJ said incredulously, simply getting a shrug from Braeburn.

“Well ya still agreed,” Brae said, before nodding towards the clothes. At Applejack’s obvious reticence, though, his expression softened, “but ya don’t gotta if you don’t want to.”

Sighing, Applejack shook her head. Even if she didn’t care so much about lying, she didn’t want to be seen as a weasel. “Alright…” she said, grabbing the clothes in her mouth. Both males watched with interest as she slipped on all four socks, pulling them up, their eyes following the movements of her muzzle from her hooves, up her cannon, and her tight, muscular stifle for the back two socks. They then watched, utterly engrossed, as she slid the panties up her back legs, before watching as they slid under her tail and covered her crotch, then were fastened around her tail dock. They could still see the cameltoe of her pouting, swollen marehood through the thin fabric as she flagged her tail aside, and that was almost more sexy than seeing her mid-orange pussy, which was only a few shades darker than her coat, bare. They could see as the fabric soon grew soaked with her breeding fluids, making the thin fabric almost invisible, though with just enough opacity to be unable to see perfectly and tease them.

“There, now what Braeburn?” Applejack asked her ‘master’, though found herself enjoying this more than she thought she would. Being told to do stuff like this by him made her feel…strange. Made her somehow enjoy being told what to do by Braeburn, to put on these marely clothes, and look sexy for the colts. She felt her filly parts doing that ‘moving’ thing again, whimpering at the tingle of pleasure that her sensitive nub rubbing against the silken panties caused.

Applejack felt the colt’s eyes drinking in the sight of her dressed so salaciously, her tail flagged aside, all just for them. For some reason she wanted them to look. She could also see her showing her pantied pussy off was having quite the effect, too. As she looked beneath the young colts’ barrels, she could see their colthoods dropping from their sheathes. Braeburn’s was a mid-brown, while Big Mac’s was so dark red it was practically black. She felt something deep within her psyche stirring at the sight, her clit winking rapidly, and her tail flagged up just as high as she could get it. She wanted to…do things to them. With them. She wanted those cocks to…do something to her. Something…she didn’t know what it was, but knew she needed it so badly it hurt, rather literally. She felt the burning in her belly increasing at the sight of her relatives’ limply-hanging dicks, and somehow instinctively knew that they were the cure to all of her ailments. If only she knew how.

“Uh…” Braeburn said dumbly, his eyes still locked on her just-hidden pussy, his lustful brain unable to form words, what with as much of his blood that was flowing to other places instead of it. “...how ‘bout ya do a little dance fer us? If ya do that, an’ one other thing, Ah promise Ah can help ya out with yer…condition. Maybe Big Mac will want to help, too.”

There it was. The answer Applejack had lacked. The solution to her problems, right there in reach. And all she had to do was dance for them. “Ahlright, um…” AJ said, before considering what to do. Still facing away from them, the filly started to sway her hips at the two males, pushing her juicy rear towards them as she rhythmically moved nearer to them, tail still high, exposing herself to them as her clit started to wink rapidly. It seemed to come naturally to her, and it felt good to be showing herself off to these males like this. Her whole body started to get involved as she spread her hind legs more, swaying her whole self and looking back at the just-stallions with an, unknown to her, absolutely smoldering gaze. Her body was positively crying out for the males' attention, even if she didn't know it.

Those limply-hanging cocks were rock-hard now, both colts gawking at the sexy display from one's sister, and the other's first-cousin. Eventually, Applejack ended the dance with her upper half on the floor, resting her cheek on the flat of her forehoof and her elbow on the floor, looking back at the two colts with the same smoldering gaze as before as she left her ass and tail high up in the air, her clit still bulging rapidly against the thin fabric. The colts’ jaws hung as low as their dicks did, before Braeburn recovered enough brainpower to speak. “That was, uh…wow…” Braeburn stammered, his whole body feeling hot after that utterly entrancing display, feeling quite the heavy weight between his stifles. It was the perfect time, he thought, to ask for ‘that other thing’.

As Braeburn walked over to her presenting form from behind, Applejack watched as his dick stiffly swung with each step. Instinctively she tensed up, her back legs going stiff again like earlier, locking her into place for her colt and to bear some of his weight, and it felt so good for her to do so. It felt right to her, too, as she kept doing that thing with her slit, feeling a tingle of pleasure each time her nub came out and rubbed against the fabric. Felt so right as she offered the colt behind her to breed her, without even knowing she was doing so.

Instead of mounting her from behind, though, despite his temptation to, Braeburn walked in front of Applejack, and as he stepped over her, she quickly found his dick inches from her muzzle. She was quickly overwhelmed by the sheer musk permeating from his crotch at such a close proximity, especially since he’d not showered after working, her mind numbing as his pheromones dug their hooks into her brain and yanked her breeding instincts to the forefront of her thoughts. She could see his stallionhood was at least seven inches long and pretty big around too, and rose herself to its level, looking head-on at the one-eyed python, her nostrils flaring out at the scent wafting off it, and her eyes widening at the sight of the most attractive thing in the world to her at the moment.

“Right, now how ‘bout you AH—!” Braeburn started, before being interrupted as Applejack closed those final few inches, and took his flare into her mouth. She didn’t know why she had, but something inside her had told her to do it, and she’d obeyed. As she felt Braeburn’s hardness flex in her mouth, she moaned, in turn causing Braeburn to hump his hips forward, driving another couple inches into her muzzle at the added stimulation. “—h-holy buck…”

Braeburn went silent as Applejack fellated the first few inches of his dick, overwhelmed by the first sexual experience he’d ever had before. Sure, he often looked at dirty magazines with Big Mac, his favorite cousin, and, sure, had hoofed himself off before, both solo and alongside Mac as they looked at said magazines, but this - this mare in heat going down on him with all the gusto of a racing Wonderbolt - was so far beyond his hoof that it wasn’t even comparable. The inside of her mouth was nearly hot, like he’d just dipped his dick in warm bathwater, if the bathwater was solid, silky, and slick too. He felt her lips and the walls of her muzzle sliding smoothly over his dick, feeling the light suction of her suckling on his upper shaft and flare, and the sensation of her stimulating him like that was completely indescribable.

“H-aaaah…sensitive…watch yer teeth…” Braeburn wispily groaned as Applejack’s front teeth gently grazed along his colthood, which she quickly corrected, folding her lips over her teeth, before she continued to blow both his mind and his dick at the same time. She gagged as he humped hard once on reflex to the sensations, his flare punching the back of her throat, and partially slid down it, with her quickly pulling her head back some. “S-sorry cuz, feels so good Ah can’t help mahself.” Braeburn said, getting an annoyed look from Applejack.

After she rearranged herself, not wanting that to happen again, his hips were humping impotently into her mouth, as she bobbed along the first half of his length. She got a little deeper with each bob, making Braeburn’s thrusts get more aggressive the deeper she got, though they were rendered fruitless by Applejack’s angle, and kept his flare safely away from the back of her throat.

Applejack, meanwhile, never thought a dick could taste so good. It felt slightly rubbery, was slightly fleshy tasting, a tiny bit salty, and…something else. The only way she could describe it to herself was that it tasted like male. Like dick. It was like nothing she’d experienced before, the finest delicacy in her needy state, enjoying the slightly-salty precum Braeburn's cock squirted with abandon into her mouth with each throb it made. It didn’t taste like much, but the stallion hormones in it made her crotch feel like it was ablaze with want, even if she still didn’t know what it wanted. She was feeling lightheaded, panting for breath through her nose, with each one only bringing more of Braeburn’s crotch-smell into her muzzle.

As Applejack looked to her side at Big Mac, she could see him sitting there and rubbing his own cock between the frog of his right hoof and his belly as he watched her giving Braeburn his first blowjob. Getting an idea, she waved him over, and he obeyed, getting close enough to stand right beside Applejack, his dick dangling heavily beneath him right beside her. Mac’s colthood looked even bigger than Braeburn’s, about nine inches long, and it was even bigger around than that of the other teenage colt. Reaching over with a hoof, balancing on her other forehoof and haunches, AJ wrapped her hoof around Big Mac’s length the same way she’d seen him do it, letting the hard flesh rest in the crook of her fetlock, before starting to move it up and down.

Big Mac stiffened up as he felt that first stroke, before he humped forward as she moved her hoof back, then pulled his hips back as she went forward, quickly getting into a natural rhythm of breeding. Soon, curious if his colthood would taste as good to her as Breaburn’s did, AJ pulled off of Braeburn, then brought her mouth to her brother’s flare and took it inside. She enjoyed his flavor more, with his cock somehow tasting more…musky, more male than Braeburn’s did, as well as how he stretched her jaw just a bit more. Applejack was only too happy to give his flare little licks and suckles, being rewarded by Mac’s pleasured moans and a taste of his precum as he throbbed in her hoof, taking a few bobs partially down his length, before returning right back to Braeburn’s needing shaft and leaving Mac with just her hoof again.

“S-stop, stop AJ…” Braeburn stammered after enjoying a couple minutes of the heated efforts of his cousin. Even if it was an extremely sloppy blowjob, with Applejack barely using her tongue at all, and only moving her head back and forth, it was still the best - if only - blowjob Braeburn had ever experienced. Not to mention the best thing he’d ever experienced. So much so that he’d started to flare in her muzzle faster than he ever had with his own hoof, feeling the pressure welling up in his pelvis that would end this interaction far sooner than he wanted it to. After all, he had somewhere else he wanted to put his member now.

Thankfully, Applejack heard his demand and, though reluctantly, heeded it. She’d been immensely enjoying what she was doing: the flavor and scent of Braeburn’s stiffness, the spurts of his precum, the feeling of each pulse it made in her mouth, the slick sliding feeling of it going in and out, the feeling of its tip swelling up thick in her mouth. Somehow, that last part had seemed…really important, and stayed with her as she looked at the thickly-swollen tip even now. She wanted to taste him more, but abided by Braeburn’s words.

“Whoo, wow...that muzzle of yers feels somethin’ special,” Braeburn said, flopping onto his haunches and letting himself catch his breath for a moment, letting his swirling mind settle down some.

“Eeyup. Her hoof ain’t bad neither,” Mac added, getting a little, prideful smile from Applejack.

“Now that ya did that fer me, Ah think it’s about time that Ah help ya with yer problem now, right?” Braeburn offered, getting rapid, eager nods from AJ.

Applejack felt more desirous than ever before, her need for that unknown thing now at an all-time high. “W-what do ya need me to do? It…it's so bad down there…” AJ whimpered needily, feeling her slit moving more, the panties so soaked through that it was as though they weren’t even there anymore, her fluids drooling down her hind legs.

“Now, Ah ain’t ever helped a mare in heat like this before, but it don’t seem too hard to do,” Braeburn said, before standing up, “Stand up, an’ leave yer hind legs open like when ya were dancin’, an’ keep yer tail aside. Lock yer hind legs too, like ya would if yer bracin’ against high winds. Ah’ll take care of the rest.”

Doing as she was told, Applejack released her brother’s dick from her grasp - to his disappointment, and with his own hoof quickly taking over the job - stood, then spread and locked her hind legs, her slit doing that movement again as she presented herself to her mate. Braeburn was taken aback by the sight, and approached her again, before carefully removing her panties, biting the strap and slowly dragging it down her asscheek, before repeating the process with the other. The panties slid off her and landed on the floor with a wet splop, with her then kicking them aside.

If Braeburn had thought her scent was intense before, now it was like he was getting bucked in the muzzle by it. Applejack needed a stallion, and badly, her body working overtime to get the virile colt to mount her and rut a foal into her womb. Luckily for her, Braeburn was just what she needed. She felt a slight pain in her lower belly, like a pinprick, and unknown to her, one of her ovaries had just released an egg. She’d just ovulated for her stud, her extremely hormonal state demanding that the colt rut her to his completion, so that his sperm could reach her egg and fertilize it, her body so ready to nourish the foal it so needed from him. Needing to be bred by him.

Following his instincts as he saw Applejack's slit wink at him again, exposing its dark-pink insides and her clit to him invitingly, Braeburn reared up, dropping part of his weight on his younger cousin’s back, and getting a short, surprised whinny from her as she was so suddenly mounted for the first time in her life.

Chapter Two: Popping an Apple's Cherry

“Wut th’…” Applejack exclaimed in surprise, her whole body tensing and, if her legs weren’t locked up, she may have bucked Braeburn right back off of her.

“It’s OK, this is what’s supposed t’ happen. Jus’ relax, an’ let me do what Ah gotta do, OK? You’ll love it, an’ it’ll get rid of that nasty feelin’ in ya right quick,” Braeburn comforted, feeling as Applejack relaxed, "but not too quick…Ah’ve heard that it feels better if we do it fer a li’l while."

“Ok…” Applejack said as she adjusted herself to accept Braeburn’s additional weight. Despite being almost completely surrounded by the larger colt, she found it actually felt kinda…nice. Feeling his weight on her croup was almost soothing, his body covering hers, like it was something she needed, if not the only thing. Definitely not the only thing. “...now what?”

“Now, Ah’m gonna put my dick inta yer fillyhood.”

“Ya what?!”

“It’s…Ah know it sounds weird, but breedin’s what gets rid of a mare’s heat. A stallion or colt puts his willy in a filly’s parts, moves his hips around fer a while, then puts somethin’ inside the mare’s belly that makes her heat go away, usually only after a few times’a havin’ sex, an’ it gives her a foal!”

“A…a foal?” Applejack thought about that. Was this what the fillies at school were talking about, she wondered; where a stallion did something to a mare while she was in heat that made a foal? “I-Is ‘breedin’’ th’ same thing as ‘mating’?”

“Yep. Breedin’, matin’, fuckin’, ruttin’, all the same thing. All end up with a mare pregnant with a foal, if a stallion or colt shoots his stuff in her.” Braeburn replied, and, for some reason, the thought of getting pregnant - of seeing her belly swell up like those of some of her aunts or cousins at the Apple Family Reunion had been, of having a new life growing inside her - turned Applejack on beyond belief.

She didn’t want to get pregnant, she needed to.

Applejack didn’t know about or consider the possible consequences of actually getting pregnant while she was still so young herself. All she cared about was getting mounted and bred until the burn in her belly was a faint memory, and unknowingly wanted her womb swelling up with a foal in the coming months. “Well, what th’ hay’re ya waitin’ fer? Get on with givin’ me a foal already!”

Giving an eager whicker at his cousin’s sexy words as he was mounted on her, Braeburn got to work doing just that for Applejack…or at least tried to. His humps were too hard, too fast, just rapidly ramming his flare against her asscheeks randomly, and even sliding between her small teats on accident a couple times. “Gosh, this is a lot harder‘n they make it look in th’ magazines…” Braeburn groused, before sliding off his little cousin’s back and actually looking at his target.

“What’re ya…AH!” Applejack yelped as Braeburn again mounted her hard, shifting his hips around some more, feeling his flare’s taps getting that much closer to her core. “Yer nearly…HAH…go left a little more!”

Braeburn followed Applejack’s instructions and soon enough, he felt something warm on his flare. His mind blanked, his breathing hitched, and his hips thrust forward as hard as he could make them, that thrust taking both their virginities within a moment.

Applejack felt like she’d been punched in the gut from behind, knocking the wind from her lungs, as well as a pain like a pulled muscle coming from between her legs. “Wh…” was all she could gasp out, feeling quite uncomfortably full and achyin her fillyhood.

Braeburn, meanwhile, was stricken silent too, but for an entirely different reason. If Applejack’s mouth had been nice, her pussy was heaven incarnate. It was so hot and squeezed so tightly around his whole dick, which he’d sunk as far as he could into her within a second, with her passage so wet that his flare had slid to her core effortlessly. He gripped her sides tightly, trembling slightly at the sensations rolling through him as AJ’s pussy spasmed around his colthood in reflexive kneading motions. “W-hah-is that you doin’ that, AJ? Th’ thing with yer…fillyhood’s insides?” Braeburn breathlessly asked, holding still within her as his brain rebooted.

Applejack didn’t know how to respond, both because she was aching between her legs from her first, sudden penetration, had the wind knocked out of her, and because she couldn’t possibly hope to put just what she was feeling into words. After taking a bit to recover, AJ gave a quiet yelp when Braeburn pulled out a bit, then slammed back in hard, making the pain in her grow. “S-stop…wait…” she wheezed out so quietly that it was barely audible from how much it hurt due to it being her first time being penetrated, taken completely by surprise from the new, painful sensation as she found between her legs stinging and slightly cramping, with that movement of the big thing between her hips that had caused it all only making it feel worse.

Getting out of his breeding haze as he heard the pained, forced tone of Applejack’s voice, Braeburn looked down at her. “A-Ahpplejack, are you OK?” he asked in a dazed-sounding tone, as though he’d just been woken up.

Big Mac watched from the sideline as his sister was made into a mare, unable to do much else than jack himself off, not with the utterly hot scene before him, and Applejack’s estrus pheromones making him want nothing more than to breed and fuck and cum in their source. After all, he knew this happened to most fillies during their first time with a stallion or colt, or a toy for that matter. Since said source was currently occupied though, his hoof had to do. “Y’OK, sis? That looked…rough,” Big Mac asked, looking concerned.

Applejack, meanwhile, wasn’t sure how to feel about the thick piece of colt-meat planted in her hungry foal-passage. It had hurt being spread apart so suddenly, and quite some too, and being winded had sucked as well, but the more she squeezed around her body’s first male guest, the more she’d squirmed beneath the still male and felt his member shifting around inside her, setting her breeding instincts alight. It was making her fillyhood feel so delightfully full instead of that aching emptiness she didn’t even notice was there before, and the more it moved in her, the more good it felt. It was like when her nub had come out against the panties, but all the way in her belly, his tip nearly touching where that itchy burn was located, deep within her core.

“H-haaaaah…” Applejack huffed, her hind legs trembling, her conscious mind confused, but her body and deepest instincts knew everything was moving along perfectly: it told her so through the thrumming pleasure coming from her pussy, right where Braeburn’s dick was buried deep, the reflexive winks of her clit against his sperm-filled balls, and the feeling of peaceful bliss blooming in her mind, rendering her speechless.

“Ah think she’d doin’ just fine now, Brae. Just…take it easier on ‘er at first. Ah think that first thrust was a mite too much for th’ poor filly.” Big Mac said, getting an agreeing nod from Applejack.

“Right, uh…sorry Ah hurt ya cous’, dunno what possessed me there,” Braeburn said, gently nuzzling behind the smaller then-mare’s ear, “Ah’ll be gentler now, OK?”

“Ah, um, Ah...ya can keep goin’ now. Ah think Ah’ve…adjusted to ya enough now,” Applejack said, squirming her hips needily. The burn had started to come back with a vengeance, her body sensing a male’s penis in her, filling her, but not breeding her. “Ah’m ready for ya ta breed me an’ give me a foal, Brae-Brae.”

Hearing that nickname Applejack had always used for him when they were much, much younger made Braeburn hug a little tighter around his cousin’s sides, rubbing his cheek against hers, sighing softly. He then pulled out a bit, getting a whimper from the filly as her passage tried to pull him right back in, but he resisted. Eventually, he pulled back…but went too far, slipping out of her. Urgently humping against her, smearing her pussy-juice all over her ass as he tried to find that warmth he’d only felt once so far, it was only a short while before he found her slit again. This time, Braeburn tamped down on his instincts, his hips quivering from the restraint as he slid slowly into her hot pussy once more. He let out a long, windy ‘mmmmmm’ as he slid deeper and deeper, until again his flare kissed Applejack’s farthest depths and his balls pressed against her clit again.

This time when Braeburn slid inside her, it felt nothing but very good for Applejack, making her join his moan as he once more penetrated her. Her fillyhood was singing with sensation as its natural pair passed back into her, making her feel complete again in a way she never had felt before his first penetration, her muscles squeezing down softly in rippling motions from base to flare on Braeburn. She felt so perfect then, relaxed yet at the same time still so tense where her lower tummy burned.

Braeburn felt the part of Applejack he was inside…gripping him, like a nearly-hot hug, and while it felt wonderful to feel his colthood constricted like that, he found that he wanted more of that sliding feeling he’d just gotten. He pulled out again, getting a wanting whine from his mate and, careful not to slide out too far this time, stopping when only his flare was inside her, started sliding back in again. Each time he did, it sent sparks of pleasure directly into his brain from his groin, each throb his shaft made within Applejack wonderful, and each squeeze she gave his member utter perfection. The slick silkiness surrounding him had little ribs in it that caught the ridges on his flare just right, making him only want to feel her pussy more and more, and leading to him starting to hump her faster and faster, again and again.

Applejack was not at all opposed, indeed starting to rock her hips back into the thrusts of the young stallion atop and within her, her own mind abuzz with pleasure as she squeezed along his length. She could feel little warm squirts coming each time Braeburn’s cock throbbed inside her, each dollop of his precum helping to cool wherever part they touched. This is right, her instincts told her, just stand here and let this stallion breed you, let him put his foal in you. Continue your species, like the good little earth pony filly you are. So she did just that, letting her instincts guide her actions as she rocked back into each thrust, her filly-honey drooling onto the ground, more forced out with each thrust, and the strands of it that hung swayed with each motion, before dropping to the floor to join the puddle already starting to grow there.

Braeburn continued to hump as hard as he could muster, which was fairly strong given he had the strength of an earth pony, each hilt ending up with his flare kissing Applejack's cervix. He was lost to the feeling of a fertile mare squeezing down on his shaft, her body begging for his seed. For his foal. Everything was building up fast, with the feelings of sliding along those ribbed, hot walls, his mare's pheromones dancing in his brain urging Braeburn to breed this needy filly, and he felt himself getting closer to his climax with each hump.

As her stud’s thrusts grew stronger, shorter, and faster, grinding his medial ring along her throbbing, winking clit with each, Applejack felt like she was losing her mind. It was all so much, yet felt so good, her body exploding with sensations, her whole backside inside and out tingling with pleasure as she fulfilled her deepest natural urges. When Braeburn’s flare swelled, and his humps grew shallow, forcing his medial ring to grind deeper against a very sensitive part in her, his flare punching against her cervix rapidly, it was all too much. She felt her passage getting tighter still as her body sensed the colt flaring in her, and with her instincts knowing he was right on the edge of seeding her, her pussy collapsed around his dick as it started to milk him for his coming climax.

Applejack let loose a loud, feral whinny as she lost control of her body, feeling her whole core flush with pleasure and relief the likes which she could never dream of. Her whole body was trembling as she felt herself rapidly clamping around the hard colthood, tingles rolling throughout her whole body as the sensations took her over. "Brae-B-Brae, p-please...Ah need..." Applejack stammered out, not really knowing what it was she needed, just that she needed it so badly, and was so close to getting whatever ‘it’ was.

As Applejack started begging him, and feeling the gushes of warm marecum on his balls as she groaned out in pleasure, Braeburn couldn't withstand the squeezing motions of a mare's pussy milking him for his load much more. As his back legs quivered, his balls pulling up to his body, his swollen flare made it harder to pull out each time, her fillyhood kneading his flare so hard deep in her pussy. Little did she know, her milking was making Braeburn's orgasm inevitable as he pounded the filly's pussy with the fury of a wild animal in rut, taking the last strokes needed to bring himself to completion.

"H-hope yer ready ta be a m-mama. Ah'm gonna...c-cum..." Braeburn snarled in Applejack's ear. It wasn’t too long before, given it was his first time, and that he’d been brought to the edge of climax once already, Braeburn felt that familiar tension starting in his pelvis. Instead of pulling out though - as a more experienced, knowledgeable stallion may do - too high on Applejack's pheromones and pleasure to do anything but follow his breeding instincts, Braeburn instead gripped tighter around his mare’s sides, thrusting as hard, deep, and fast as he could. Feeling that pressure within his groin just growing ever so much tighter. It wasn’t the only thing growing tighter, though, as he hit that wall at the end of his cousin's passage again…but this time, his flare just kept going.

Applejack just took the pounding, her mind too blissed-out to know what was going on, besides the feelings of it; how the ridges on Braeburn's flare ground against that special part in her that made her see stars, how his ring rubbed against her constantly-winking clit, how slickly and smoothly he slid into her after her orgasmic fluids lubed him up so well. How his blood-glutted flare continued to pound against something deep within her core, then slipped just within. It felt weird, him sliding so much deeper into her, but not painful, and at the same time it felt right to feel her male so deep inside her belly. Unknown to her, he’d just penetrated her estrus-relaxed cervix, driving his flare into her fertile womb.

"Hnng-yes! Take it all!" Braeburn grunted, feeling that tension in his pelvis building, building...then pop. Braeburn pressed his hips against Applejack's as hard as he could, his flare slipping past and sealing just within her relaxed cervix, swelling as thick as it could. He trembled as he felt his cock throbbing rapidly and repetitiously as it disgorged his first shots of potent, pent-up colt cum directly into his cousin's womb.

Braeburn tensed up as throb after throb of his virile semen spurted into Applejack's needy womb, gushing out his long-held load deep into his mare, loosing his billions of virile, young sperm to seek out her fertile egg. Everything was signaling to his instincts that he was impregnating this mare right then, breeding her, even if he didn't have the state of mind to realize it. And it felt so good to breed her.

Applejack, meanwhile, felt those sensations of squeezing and bliss renew as Braeburn started throbbing inside her, feeling a warm, thick wetness starting to pool deep in her belly, right where that hot, itchy feeling had resided all day. It was like aloe on a burn, instant relief, and she found she only wanted more. Luckily, Braeburn's body was more than glad to provide it, in fact giving her everything his young glands and balls could produce, doing its best to knock this filly up with his foal.

Braeburn's orgasm was so much better as Applejack came while he did, her inner muscles drawing his bountiful adolescent spunk directly into her uterus with rhythmic contractions from his base to his swollen flare, her orgasm milking him for each drop, the deep pleasure of continuing their species blending with the physical pleasure to make this orgasm addictively good.

Each squirt made Applejack's foal-oven swell just a little more, making her midsection bulge with his load, each clench from her only heralding the next, until she looked a couple months pregnant already. All good things must come to an end though, and after his fifth shot, and several dry throbs, Braeburn was finally spent.

"T-that was...ya felt so...mah...mah belly's so...warm, an' full..." Applejack huffed as she felt Braeburn's throbbing colthood fall still inside her, his softening flare slipping from her womb, and leaving her lower belly filled so full. She felt soothed now, and knew instinctively that this was what her body had needed all along, “...s-so good…”

It took Braeburn a while to come down from his explosive orgasm, especially as he felt Applejack's body still nursing his member for the last drops of its colt-milk. He collapsed onto her back as his cock dryly pulsed in her pussy in post-ejaculatory spasms, panting as he tried to recover some fragment of his orgasm-shattered mind. The compliments from her as he drained his last into his mate was the cherry on top, making a dazed smile cross Braeburn's face as he heard just how good he’d made Applejack feel put into words, as he spent his final dribbles into her well-filled womb.

Braeburn hadn't felt so relaxed in...ever, feeling himself growing soft in the perfect receptacle for his stallionhood post-orgasm: deep inside the freshly-seeded pussy of his well-bred mare. He wouldn't pull out until he naturally slid from her, savoring the gentle post-orgasmic ripples of Applejack's muscles over his dick, drawing his billions of sperm deeper into her womb, so one could join with her egg awaiting it.

"Is...is that all? Is that sex? That’s what makes a foal in a filly?" Applejack asked, feeling as Braeburn's turgid length was slowly sliding out of her as it softened, and eventually slid out of her fully with a wet, squelching schlick. She felt a dull ache deep within her as his shaft came out, like a strained muscle, but it was a good kind of ache. One that told of a job well done. “Ain’t like that wasn’t enough though! Holy hay that felt good! Feels so nice an’ relieved in mah belly now…”

As he heard the question from the mare pinned beneath him, Braeburn nodded. "Mmmhm, 'at's sex. An' ya have such a good pussy...felt so good t' squirt inside ya, instead'a all over mah chest or th’ ground like usual." Braeburn mumbled out, his hips shifting softly, despite only grinding his semi-flaccid, cum-slick dick against her ass fruitlessly, painting it with their mixed cum.

“So that’s how foals’re made…” Applejack mused, feeling Braeburn’s excess cum drooling down her clit’s hood, the stimulation coaxing another wink from her, before looking back to the small puddle of gooey white and clear stuff that had formed between her hind legs, as Braeburn's and her own cum drooled from her in a small, steady stream.

“Yep, that’s how foals’re made…” Braeburn confirmed, neither pony realizing the depth of that statement in their hormonal states.

Applejack was feeling so satisfied on a deep level...yet she also felt like she wanted more, that heated feeling still glowing like an ember in her belly, and growing hotter yet every second she was left empty. As she looked over to her brother, seeing his dark, red spire still hard as he slowly stroked it while watching the climaxing pair. It was clear he was holding out on cumming, saving his first, biggest, and most virile load for his turn with the fertile filly. It looked so much bigger than Braeburn's, longer and thicker by a bit, that she wondered how it'd feel inside her, stretching her that much more than Braeburn’s had. She wouldn't have long to wait to find out, though, given just how ready her big brother looked to mount her.

As Big Mac walked over to them, Braeburn reluctantly dismounted Applejack and slid from her back and the larger stallion quickly sidled up behind his little sister. He could smell her need, and could feel his partially-flared cock slapping against his belly as her cum-drooling slit winked at him, making him give a soft breeding whinny in response. "Ya ready fer me?" Big Mac asked, his voice deep, showing his barely-restrained need for her. "Cuz Ah'm more'n ready for ya..."

In response, Applejack stepped forward and flagged her tail aside, fully revealing her semen-covered fillyhood lips to her brother, looking back at him with a desirous expression. Sure, the heat in her belly was lessened now, but her mind still drove her to accept the other stallion too, to take in his billions of sperm as well and give her an even better chance of getting pregnant. “Go ‘head bro. Give it to me good.”

Needing little more encouragement, as close as he was to his own orgasm, Big Mac all but lunged at Applejack, mounting her in an instant. She felt his weight on her croup and back, his flare tapping against her butt, just like Braeburn’s had when he’d first covered her, but with his feeling bigger than his cousin’s by far. Mac’s flare almost felt as big as Breaburn’s had been when he’d squirted in her! It wasn’t long before she felt his flattened tip press to her recently virgin petals, before she felt herself spreading between her hips once more. Applejack groaned as she felt even more opened up inside than she had with her cousin’s colt cock, making her groan out at the extra stretching sensation, squeezing down as well as she could around the larger colt’s breeding tool.

Big Mac, meanwhile, was speechless at the feeling of the first pussy he’d ever had, with it squeezing around him, Applejack so slick from Braeburn’s and her own cum that he slid to her core effortlessly. His hips quivered and his dick throbbed, making the filly feel like her whole body lurched with the mighty motion. “H-holy hay bro…yer so…big…” Applejack grunted, her own back legs shaking from his heavier weight on her rump, as well as the feelings his thicker shaft was giving her.

“Ya feel so…warm…tight…” Big Mac managed to mumble out, fireworks of pleasure shooting off in his brain as his dick sunk deeper into Applejack, his huge flare kissing her cervix.

“Ya like mah tight li’l fillyhood, don’t ya big bro?” Applejack asked, taking a moment to find the right muscles, before squeezing down on Big Mac’s big dick of her own volition for the first time.

“E-eeyup…” Big Mac managed to force out, so overwhelmed by Applejack’s core squeezing on him, and the sheer heat and slickness of her fertile pussy, that he couldn’t even thrust yet, just quivering as she milked him.

“Then fuck meh some more! Ah want yer foal too, big bro!” Applejack exclaimed, grinding her hips against his impulsively. Like a fire was lit under his ass, Big Mac snorted at her request, then all but yanked his steel-hard cock from her grasping pussy, before ramming himself back in, getting a grunt from his sister in return from the force of it. She gave no resistance, however, pushing right back into his next thrust, feeling him bypass where Braeburn had reached; feeling his flare sliding past her cervix and into her womb too. That feeling, while mildly painful, was also deeply satisfying, her instincts singing praises to her for finding another such worthy stud to reach so far into her again, and eventually deposit his seed directly where it was needed too. She took everything he gave her gladly, clenching her newly-discovered muscles down on him with each thrust.

Big Mac was feeling overwhelmed already, with as close as he’d gotten himself with Applejack’s and his own hooves, and her mouth. He felt his flare swelling up thicker yet, that tension in his pelvis growing to be nearly unbearable after only the sixth thrust into his mare. “A-Ah-pplejack…” Big Mac said urgently, but AJ could already tell what was happening; could feel his colthood and flare growing ludicrously big in her passage and womb, so much so that it felt like a foal had shoved their whole foreleg and hoof into her.

“By Celestia yer flare feels so huge…y-ya gonna squirt yer colt-goo in meh too…gonna gimme yer foal like Brae-Brae did already?” Applejack asked, her tone dripping with desire. She didn’t know why, but she’d loved the feeling when Braeburn’s tip had gotten all huge and he squirted his colt-stuff in her, and wanted her big bro to do it with his colt-goo, too. All she knew is that she had to have his dick deep inside her when he did that squirting thing, so it could put all his spunk right where it burned. “G-go ahead, do it! Please! Ah w-want it naow!”

“EEYUP!”

Big Mac, already at his limit, gave one more big thrust, as hard as he could, when he felt the tension behind his balls snap. Feeling a rush of intense pleasure as his flare swelled fully in her foal-room, its tip pressed against the back of his little sister’s womb, Mac's shaft throbbed hard, then again and again as he finally loosed his seed into where it belonged. He felt as she squeezed gush after gush of his semen from him, pleasure overriding all his senses as he pump, pump, pumped his sperm right into her furthest depths, the force even flooding her Fallopian tubes with his and Braeburn’s virile spunk.

Applejack quickly realized that his cumshot was even bigger than Braeburn’s had been, and went even deeper. It was so much in fact, and with her being as full as she already was with Braeburn’s load, that Applejack’s womb could hold no more. A mix of both colts’ sperm started rushing out of her, even past her tightly-stuffed cervix and pussy, splattering out and onto the totaled floor. But Big Mac kept cumming, shooting his pent-up adolescent seed deep into his sister’s ripe womb, all but completely washing the other colt’s load out.

“Oh buuuuuck yeah!” Applejack cried out in ecstasy, as she felt her pussy explode once more into those wonderful squeezy motions, overtaken by the feeling of being filled so thoroughly again, that full feeling deep in her womb, and her clit winking against Big Mac’s throbbing balls setting her over. She started squirting her marecum out to join the colts’ cum already on the floor as she milked him for everything she could, blankly looking over with pleasure-glossed eyes at Braeburn, her tongue lolled out as she came even harder than before, drawing out every sperm cell she could get from Big Mac’s big balls. The sight of his cousin in such ecstasy, and Big Mac’s tense expression as he unloaded everything he had into her, had Braeburn at half-chub again, hanging limply from his sheath as he watched his cousin getting bred by her own brother.

Eventually, the torrent into her womb and from her pussy ended, reduced to mere dribbles as Big Mac’s pent-up supply finally went empty. His flare was still swollen huge, plugging up her cervix and keeping her womb full with what of his load hadn’t escaped past it as he pulled his hips back some to do so. He still felt the occasional dry, fruitless throbs he made inside her, each one bringing a tingle of pleasure, but he knew he was spent for the moment. He felt kind of bad that his first time with a mare had ended so soon, but it had felt - and still felt - so good that he couldn’t dwell on it for too long.

The feeling of Applejack’s foal-canal gently squeezing on him still, even as he grew soft in her pussy, made him remember that he’d not left her unsatisfied, with as wet as his balls felt with her cum and the memories of her clenching rhythmically around his cumming cock, her hungry womb suckling his flare for his sperm. Soon he felt his softening colthood slide from her and he dismounted, his muzzle inches from her cream-filled pussy as he did. His nostrils flared at the scent of his and Braeburn’s cum mixed with her fecund scent, making his limp dick throb despite its exhausted state.

“W-wow big bro…ya squirted so much in meh…an’ outta meh…” Applejack panted out, standing there on wobbly legs, tail still flagged. She was feeling much better after having taken two loads already, but as she looked to Braeburn and saw him at half mast again, that desire for more cock reared its head once more. “...but Ah kinda want more.”

“Sis…Ah need a few minutes…an’ some water…before we do more. Ain’t sayin’ no, by th’ Earth Ah ain’t, but…stallions an’ colts need t’ rest a bit after cummin’.” Big Mac said. Here he was, still feeling the aftershocks from his orgasm, and Applejack wanted more from him!

“Yeah, sorry AJ, but Ah think Ah need a few more minutes too. Ah do wanna do that again, though, an’ soon!” Braeburn said as Applejack then looked at him.

They then took a small break, the two stallions relaxing, laying on their backs with a nice cool drink, while Applejack had guzzled hers down and instead bided her time by gently nuzzling the colts’ balls and sheathes, drawn to their colt parts like a bear to honey. Big Mac’s balls were larger than Braeburn’s, she realized as she hefted their sacs with her nose one after the other, but Brae’s softer scrotal fur felt so much nicer on her nose. They were both half-mast as she nuzzled their sensitive balls or shafts, taking in their musk, getting that much more horny with each huff of their virile, stallion-y scent. “Right, ya ready t’ fuck some more yet?” Applejack asked after about half an hour of nuzzling and gently licking their junk while they were recovering, alternating between nuzzling their balls and licking their half-erect colthoods. Her pussy and womb were burning for more sex, especially upon seeing them both at full-staff now.

“Eeyup, Ah think so.” Big Mac said, feeling like he was quite ready to top the young mare again.

“Ah could go for some more too, with as good as ya nuzzlin’ my balls an’ dick felt,” Braeburn said, giving Applejack a sexy smile, “but what would ya say t’ doin somethin’ a bit…different this time?”

“Different? How?” Applejack asked, Big Mac looking just as curious.

“Well…ya ever heard of somethin’ called ‘double penetration’?”

Chapter Three: Cross-Pollinating An Apple

“Y’sure about this?” Applejack asked, once again feeling the weight of an older colt on her back, and the warmth of another against her chest as she squatted over and laid chest to chest on her brother, legs spread to the colt atop her and beneath her both.

“Sure Ah’m sure,” Braeburn replied, looking down on her as he took the opportunity to mount her again, “Ah read about it in a magazine, an’ it seemed like a lotta fun fer all involved. But ya need a lotta lube t’ go in somepony’s anus, else it’ll hurt a lot. An ya got a lotta lube right…down…’ere.” He ground his flare against her cum-oozing pussy, emphasizing his point.

“Well…hurry up’n get on with whatever yer doin’! Ah want more sex!” Applejack groused, though her attitude sure changed as she felt him easily slip into her pussy again, sliding all the way to his balls into her, him savoring her warm, clenching depths, and her his filling dick, for a moment, before pulling out again.

“There we go, all lubed up. Now then…” Braeburn said, feeling quite eager as he heard his little filly cousin, whom he’d seen grow up into the beautiful young mare she was now, literally begging for his cock up her ass, who was Braeburn to refuse her offer, he thought. So, with a firm push of his hips, he pressed against her virgin ponut.

Brae started cramming his cock more firmly against Applejack's pucker, trying to enter, but found that it was tighter than her pussy was. Way tighter. "Oh c'mon!" he grunted in frustration as he tried to enter her rear, to no avail. That round pucker just wasn't giving in to his flare's demands, even with all of the lube he had on it.

AJ wiggled her butt impatiently in response, her desire to get back in the action, to be penetrated and filled again growing to be intolerable, the burning in her pussy growing as it was left empty. "Put it in already, Brae-Brae!" Applejack said urgently, pushing back onto the flare against her asshole.

Getting frustrated, smelling the heated mare beneath him, hearing her beg for his cock, and wanting to get his dick inside her again, Brae pulled back a little, preparing to enter her with more force. As he rammed his hips forward, he felt that seemingly impenetrable sphincter's tightness nullified under the force of his thrust and the lube. While it worked, and Braeburn felt the warmth, and a tightness he couldn’t have even imagined compared to her marehood, of his mare surrounding his colthood again, it didn't lead to the desired result from Applejack.

Applejack loudly cried out in pain, with Braeburn's penetration feeling like she'd just gone a massive number two, but in reverse. Her bowels strained at the sudden intrusion, it felt like when Braeburn had suddenly entered her pussy, her lower belly aching once more. "What the buck, Braeburn! Ya just...rammed it in meh again?! That hurt like Tartarus!"

Despite the pleasant tightness and rippling contractions around his upper shaft and flare, Braeburn's mindset immediately changed to being worried about the mare his dick was stuck halfway into now, not moving at all, not wanting to potentially cause any more pain than he already had.

"S-sorry cous'!" Braeburn said, feeling guilty that his rashness had hurt his cousin for the second time that night.

"S-stop, jus'...don't move. Gimme a sec," Applejack said, then, when her overeager cousin did as he'd been asked to do, she let her body adjust to its intruder, just like she had when he'd taken her vaginal virginity, meanwhile testing various muscles in her abdomen to find the right ones to relax. As she untensed a specific group of them, sure enough, it started to hurt less as she gave him more room, and her body adapted to being filled there too.

"Sh-should I pull it out again?" Braeburn asked worriedly, despite that being the last thing he really wanted to do.

The offer of Braeburn wanting to pull out triggered something inside Applejack; she did NOT want him pulling out, leaving her empty again. "NO!" Applejack sharply exclaimed, before clearing her throat, her cheeks flushing a bit at her outburst, "What Ah meant is, ya don't gotta pull out, but please start pushin' in slow when ya do...or at least slower, yeah? Or do ya even know what slow is, Mr. Freight Train?"

"Sorry..." Braeburn said, giving a small indignant huff at the unwanted nickname, before starting to slowly slide deeper. The lube had started to dry out a little bit, making his lower shaft tug some as he entered her further, but it wasn't enough to be painful, simply making more friction.

Big Mac, meanwhile, waited throughout all of this, pinned beneath the two fucking ponies. His desire to penetrate his sister again was slowly beginning to grow stronger and stronger, and he was starting to struggle with containing himself. As he heard her in pain, however, the empathy he felt for his sister in this situation showed in a kind of wholesome, brotherly way, his forelegs reaching around her neck, embracing her and rubbing over her crest as Braeburn slowly went further into AJ's ass. Being hugged while she was trying to get used to the new, somewhat strange, still mildly painful, but nonetheless enjoyable sensation helped Applejack more than she'd ever admit. Leave it to her usually-rival brother to be there for her when she needed him most.

Simultaneously as he held her, Big Mac's member was ever so slowly teasing AJ's clit as it flexed in anticipation, gently rubbing against and over her vulva, since his natural desire to penetrate the mare in heat never escaped his mind, and less so his body, entirely.

Every slow motion, every gentle thrust Braeburn penetrated AJ with, got her more and more used to her ass being filled, until eventually the initial pain from her cousin's inexperienced entry faded away entirely. Meanwhile, Big Mac's patience slowly came to an end, his cock drooling precum with each throb. Feeling through the bulge it made in her belly against his own that Brae was then going in and out of Mac's sister at a reasonable pace, and the quiet moans those thrusts got from both of them, he figured she couldn't be hurting that badly anymore.

"I'm waiting for yer OK, sis! Ya ready fer me ta get back ta fuckin' yer pussy too?" Big Mac asked, not so subtly hinting towards his burning desire to join back in on the action. AJ was apparently a little too focused on relaxing the right muscles, and the pleasure, then to think about there still being another member to enter her needing fillyhood.

"S-sure, go 'head, bro!" Applejack moaned out, winking her clit against her brother's tip in invitation. She was meanwhile getting used to the new feelings of Braeburn taking her in the asshole; it wasn't quite as pleasant to her as having a dick in her pussy was, but it felt...different. It had the same feelings of fullness that she craved, and it kind of was like when a penis was in her foal-canal, but...not; it was more of an echo compared to the much stronger pleasure she felt when she was being penetrated in her fillyhood. But even a bit of that feeling was still quite nice.

Mac pressed his flare to Applejack's winking pussy, awaiting the right moment to enter. He observed Brae's pace for a short while, trying to follow the agreement that they had made to have only one penis inside AJ at any time. Timing it as Braeburn pulled out, Mac pushed in. As wet as everything was - including AJ's regular juices, those from her most recent orgasm, as well as most of their cum still sticking around - and with her looser from them already having had their first little experiences of getting into AJ's passage, it was a smooth entry, Mac sliding balls-deep in seconds.

It took a while for the colts to get the pattern down, each craving to be buried into the warmth of the filly they were sharing: either one started to penetrate while the other was inside, one enjoying Applejack's warmth for too long that they didn't pull out in time, or neither thrusting before the one hesitantly did as they forgot their order, but eventually they got the hang of it.

Braeburn, meanwhile, couldn't believe how much tighter Applejack's rear hole was, with the lesser lubrication, and thereby higher friction, also letting him feel the texture of this new hole better than her pussy. Unlike said pussy, her rectum was much smoother than her ribbed vaginal walls, though still had these little curves in it that still gave plenty of stimulation. Every time he entered, her anal walls would ripple along his dick, as though trying to push him out. It was almost a sheer contrast to her pussy seeming to pull him in, though it was not a contrast he minded much, as he just pushed harder against the contractions, getting deep into the warm tightness his colt-dick craved.

Despite the rocky start to Braeburn entering her, Applejack groaned at the sensation of being filled like this now, the feeling of taking it in two holes at once while so sensitive from her estrus, of how filled it made her constantly feel. Before, when only one stallion was in her pussy, there was always a delay before the colthood within her would enter again after each thrust, while with the alternating thrusts Big Mac and Braeburn were taking into her, she was never left empty.

While Big Mac loved the tightness of his sister's little fillyhood squeezing around him, he was unsure how Braeburn was doing; but if the utterly blissed-out expression on his face was any indication, he must be feeling at least as good as he was. After blowing his first quickshot load, Mac was lasting much longer his second round, as he found it always was, quite enjoying his mare's canal now that he actually had the time to savor more than just six thrusts, giving evermore when it came his turn to enter the heated filly's pussy again.

Applejack felt pressure building in her lower belly faster than with either colt, her inner muscles squeezing down frequently and randomly, her clit a flurry of near-constant winks.

"G-guys...oh mah Celestia YEEEEEES..." Applejack forced out in the most lustful, adoring tone a filly could make, feeling so good as both colts pistoned in and out of each of her holes. Unable to even warn them with how suddenly it came on, Applejack let out a feral whinny as her third orgasm, this one stronger yet than either of the others, overtook her just as Big Mac entered her to the hilt again, with his flare pressed to her cervix. The pleasure rolled through her whole body as her walls started squeezing down rhythmically on her big bro's cock again, soaking his and Braeburn's balls with her squirts of marecum. Her body was trying to have a repeat performance of getting him to blow his load in her early once more, though that was not to be this time.

"There ya go, let it all out...holy hay yer tight li'l number clenchin' down on me feels so good..." Big Mac said, and, as he felt his sister cumming again, he nuzzled into and kissed her neck, rubbing her back as she trembled in his grasp. Her whole self quaked, with Applejack unknowingly having her first-ever full-body orgasm. Mac meanwhile enjoyed the feeling of her vaginal walls milking his dick, giving a quiet 'mmm' as it throbbed in return, depositing yet another glob of precum onto, and into, her relaxed cervix.

Braeburn felt as she squeezed too, but only on his flare, though what he did feel was like her ass was squeezing the life out of him. "Holy hay ya can squeeze, cous'!" Braeburn exclaimed, though neither of the other ponies were really in the state of mind to respond to him; one cumming her brains out, and the other enjoying the milking on his dick and the quaking mare pressed against his chest. Brae nuzzled her crest as she squirmed and shivered, waiting for her orgasm to end so he could get back to fucking his cousin up the ass.

AJ's body was visibly shaking from the pleasure, taking a few seconds after to regain her balance as she was panting, the exertion that such an overwhelming release caused making her enter a state of exhaustion that didn't feel like when she worked, but enjoyable.

Seeing and feeling that Applejack had recovered from her orgasmic journey into bliss, Braeburn could feel how the extremely tight grip of AJ's anal canal loosened some around his flare, allowing him to slowly push his member back into her, temporarily forgetting about their previous agreement, only wanting to feel the warmth of the filly's rectum surrounding him again.

Big Mac was still deep inside AJ, able to feel how much tighter her pussy got as Braeburn entered at the same time, as both were in AJ to the hilt simultaneously, neither noticing their balls pressed firmly together until one's pulled up slightly when their dick throbbed. Not that either really cared, with it just being more stimulation to their frazzled young minds.

Applejack moaned loudly with as much as this was stretching her; it didn't feel bad though, now that her body was more adjusted to being penetrated, and she in fact found herself rather enjoying the almost, but not quite, painful stretching.

"W-wow..." Applejack said, her voice having the same awe-struck tone it had held when she'd seen the giant rainbow explosion that had guided her home, and led to her getting her cutie mark.

"Yeah, 'wow' indeed..." Mac replied, his hooves wrapped around Applejack's neck, hugging her softly to him, and her burying her muzzle into his chest.

Both colts also realized then just how thin the inner walls of a mare were, and how easy it was to feel through them; with their shafts only separated by a thin wall of flesh, that fact really came to bear. Each throb the one's dick made was felt by the other, and it was a new sensation to them; unexpected and kind of weird, but not entirely unpleasant. Braeburn felt Mac pulling out, with him following suit, and soon they both adjusted back to their original technique and pace.

"Hey, uh...how bout ya both go int' me at th' same time 'gain? That felt...wow..." Applejack said a few alternating thrusts later, wanting to get that ultimate, satisfying fullness again.

"Uh...sure, iffin' ya think ya can take it," Braeburn said, and Applejack snorted at the challenging tone.

"Bring it on!" Applejack said back with as much confidence as her tired body could muster, which wavered slightly as both colts rammed into her at the same time. She could only groan deeply, her hind legs quivering, her small holes and pelvis straining to contain both colts' cocks at the same time. But holy Celestia what a rush it was! She came a second time when both cocks filled her again, still sensitive from her previous orgasm, her whole body quaking in another full-body climax as she gushed her filly-juices all over both colts' balls, milking both colts at the same time.

When Applejack recovered, practically limp as both colts pulled out, then hilted balls deep, their nuts crashing together each time, they could feel their cocks rubbing against one another's within her, feeling a hard dick on their own only separated by AJ's wall. It was weird, and felt kinda good, though the extra tightness of them both sharing the space at the same time made it quite worth the weirdness.

Eventually, the sensations of fucking AJ led Mac and Braeburn close to their second orgasms, both colts physiologically and psychologically drained, but they still had the energy to keep going. Eventually they both hilted again, panting from the exertion of all the thrusting, with even their earth pony stamina having its limits, and not helped by their sexual inexperience. Unsure if they should pick up the pace and finish in AJ’s warm pussy and ass, or if they should slow down and try to drag this out more, Mac leaned up and nuzzled Applejack's cheek to get her attention.

"H-hey AJ? Y'need some more...?" Mac asked weakly, but didn't receive a response. Applejack looked almost catatonic from cumming twice in a row, in a pleasured daze as she was so widely filled with cock, and squeezed over them with her fillyhood greedily.

"C-cum in meh again...please...both'a ya..." Applejack begged. Her womb was burning hot from her two orgasms without a colt's seed accompanying them, and she wanted to feel that relief again. She could feel them both flaring in her, making her mind even more frazzled as she was overstimulated by that extra stretching. At the same time, her instincts were overjoyed as she felt her stallion flaring in her pussy again, his urethral process pressed against her cervix, ready to douse her heat with his virile sperm once more.

"Alright then! C'mon cous', let's pick up the pace!" Brae responded, only too eager to feel the wonderful sensations of pumping his cum into Applejack's womb again, and immediately beginning to thrust down into her ass with the speed of an overly excited colt. Big Mac followed this narrative without hesitating, eager to feel his own orgasm, even if his endurance was waning.

At this speed, their hips crashing into Applejack at the same time, both stallions struggled to keep pace, all but wildly humping into their shared mare whenever they could at that point. She groaned in mild pain at the rapid stretching - further than ever before, with their swollen flares pummeling her insides at the same time - but mostly pleasure, now that she'd gotten used to it. The overwhelming stimuli left her struggling not to just collapse onto Big Mac with each thrust of the two who mounted her. Her legs certainly shook heavily though, threatening to give out on her, as did, unknown to her, Braeburn's.

His member quickly stiffening even further, his flare growing even thicker, Big Mac knew he was right on the edge. After only a few thrusts more, his orgasm was approaching fast and, instinctively, in order to make sure his sperm was going right where it belonged - as deep into his mare's fertile tract as he could make it get - he thrust deeply one final time. Big Mac saw white as his balls pulled up to his body and his cock stiffened, before it started throbbing rapidly. He felt as he slid past that ring-thing deep within his sister’s core again, and something firm pressed to his flattened flare.

For the second time within an hour, Big Mac's body proceeded to release his virile genetic payload against the back of his little sister's womb. Wrapping his forelegs around her tightly, Big Mac groaned as he pressed his head back into the pillow. The sensations were almost overwhelming, but his body was staying almost entirely still as his cock rapidly jerked inside his mare, except for the mild spasms he inevitably underwent, his muscles locked in place to force him to keep seeding his mare.

The feeling of having her estrus quenched with a colt's foal-gravy pouring deep into her burning belly again made Applejack moan in pleasure, her body set over the edge once more as she received another intrauterine injection of her brother's soothing balm. Her body, tired as it was, twitched in another powerful orgasm as her foal-passage milked her stallion dry of everything he had left to give her...and, despite it being Big Mac's second climax in so long, what he had to give was quite a lot, pump after hearty pump of his seed messily splattering into her ripe-for-foal core.

As Big Mac kept filling his sister's womb with his smaller - but still plenty virile - batch of foal-cream, Braeburn, who'd been close to cumming too, was sent over the edge by the sight and feeling of Big Mac's orgasm, and felt himself flare fully. Mac's cock throbbing rhythmically against his own through that strip of flesh that separated them, the thought and memories of how it felt to fulfill this desire of throbbing his own seed deep into a mare in heat's womb, tipped Braeburn over his edge. Well, that, and the fact Applejack's ass was milking him tighter than even her fillyhood could as she came. Tensing his kegels to practically force himself to cum as he so wanted to, to climax in time with his cousins, Braeburn thrust as deep as he could before coming at a standstill at the deepest point in' AJ's colon as he released his semen into her, only mildly delayed with Big Mac's orgasm.

Both colts proceeded to empty themselves into her, their balls and cocks throbbing against each other, but neither even noticed that, the only thing they were focused on being the fireworks of bliss going off in their brains. They gave Applejack everything they had, and her body only too greedily took it, her rhythmic contractions working to draw out every drop it could.

As their powerful orgasms ended some time later, Applejack collapsed down onto Big Mac, and Braeburn onto her, sandwiching her between them and turning them into a particularly pleasured pile of ponies, all three gasping for air as their bodies finally came down off their highs. Both colts were still hilted balls-deep into their mare, their flares still swollen huge in her - Big Mac's plugging up her cum-filled womb from the inside her cervix again, and Braeburn's just beneath Mac's as he contained his own load in her colon. The sensation of being so utterly corked with cock and cum was a satisfaction that went beyond just a simple orgasm for Applejack. That fullness, and the fact that she'd been bred again, too.

Braeburn nuzzled into Applejack's neck as he held her barrel loosely with his forelegs, and Big Mac had his own forelegs wrapped loosely around her crest. As she lifted her head and looked at Mac, he met her eyes, seeing in them exhaustion, and a kind of satisfaction a brother should never see in his sibling's eyes...especially not while hilted balls-deep after cumming deep inside of her. Before he knew what had happened, Mac was surprised as he suddenly felt her lips on his, her forelegs wrapped around his neck and pulling him into it.

When he recovered from the shock of Applejack stealing his first kiss so suddenly, Big Mac pushed back into it, tightening his grip on his sister and pulling her tighter against him too. They kissed for a while as they enjoyed their afterglow and first kisses, lips softly smacking together as they did so, eyes softly closed in pleasure.

Eventually, Applejack pulled back, a thin strand of saliva still joining their lips, before it soon after snapped. "Wow, so that's what kissin's like..." she mused, having just given her first kiss to her brother, "...Ah think Ah like it," She paused, before sticking her tongue out to lick her lips, getting a taste of her stud. "Hmmm, ya taste good, bro."

Big Mac was just lying there stunned, a combination of his sister's and his drool on his lips. For some reason, even after rutting her brains out twice, something as intimate as a kiss was what broke his brain. "Ya taste good too, sis, but...what was that fer?" Big Mac asked after getting some semblance of thought back.

"That, was a thank ya fer helpin' me with mah heat," Applejack replied, giving a little smile, "Ah owe Brae-Brae one too." With that, she turned her head to where Braeburn's head rested on the floor beside them, lidding her eyes at the colt looking back at her, before pressing her lips to his too, exchanging their tastes with one another for a little bit.

Soon after Applejack broke her kiss with Braeburn, both colts slid from her, Braeburn's member seemingly spent and starting to retreat into his sheath...but Big Mac's still stood semi-hard. She still found herself wanting more despite her tiredness, her instincts seeing a stallionhood ready to give her more sperm, but she couldn't will herself to move. Maybe in a little while, after some rest, she'd ask Big Mac if he wanted to go again. Braeburn, meanwhile, seemed completely done, his colthood sheathed again, his forelegs folded under himself and looking on the verge of falling asleep, so she decided to not bother asking him to go again.

Big Mac however...

"Wanna go again, after a little break?" Applejack asked a few minutes of rest later, getting an eager smile from her big brother.

"Well, Ah did promise t' help ya with yer heat until yer satisfied..." Big Mac said, getting a small smile back from the filly beneath him. "...an' with how good yer fillyhood feels, Ah'd be a plum fool t' refuse gettin' ta feel yer pussy again."

After both had caught their breath, Big Mac at full hardness again thanks to his little sis's rubbing hoof, she leaned over the edge of the bed this time, with her hind hooves on the floor and her forehooves folded under her chest. As she looked over to Braeburn, sure enough, he was snoozing peacefully, and AJ smiled at how both handsome and cute he looked at the same time like that. "C'mon bro. Think ya got one more in th' tank?" Applejack asked, and got only too eager of a nod from Big Mac as he stood from the floor, then walked behind her before rearing and once more mounting over his sister, his shaft resting over her croup.

"Eeyup."

Chapter Four: An Apple's Bloom

Big Mac hesitated a moment before sliding inside his sister again, letting his warm, hard member grind over her croup. He was honestly getting quite tired after two rounds with the estorous filly, his balls starting to lightly ache, but he felt he had at least one more good one in him still. Plus, he’d be quite remiss if he were to refuse to get to take Applejack’s soft, warm, fertile pussy again. He ground for a while before hearing Applejack whimper and push her hips up towards him, letting it slide down, naturally following the curve of her stifle down to her marehood and lining up with her puffy, slick, and eagerly waiting vulva.

"Come an’ breed yer sister again, big bro. Ah’m sure you’ve got a little more in yer tank fer li’l ol’ me, don’t ya?” Applejack said, before performing a strong, prolonged wink that left her clit outside of her for several seconds against Mac’s flare, feeling him shudder atop her and making his member throb against her.

“Eeyup. One more creampie, all fer yer womb sis. Ah, uh, think this is th’ last one Ah got fer ya though…but what we already gave ya should be more’n enough to keep yer heat under control fer a while.” Mac said, and, wasting little time, Mac pushed his hips forward. Applejack’s lubricant and semen slicked, and slightly loosened, marehood gave no resistance as he pushed his hips forwards once more, taking in the sensations of again smoothly sliding into her pussy as she pushed back towards him, helping him slide inside her deeper and deeper.

Applejack's walls hugged around him, welcoming him in as much as their hips’ movements were, and Mac once more found himself in elysium. It didn’t take long for him to hilt her again, and when he again felt that ring he’d pierced twice before on his flare, he shuddered pleasantly as he let his tip once more kiss the mouth to her fertile womb. That feeling still sent shivers down his spine, knowing that what lay beyond was where a foal could one day grow. His foal. He could make a foal with Applejack right now…and probably, he didn’t realize in his altered state, already had, just thinking it was all sexy talk.

Applejack felt her mind buzzing with pleasure, her inner muscles clenching down on its guest, her head easing back so it pressed against the side of her brother's chest and neck. "Hmmm…’at's what Ah needed...a big, thick colt-cock spreadin’ me open again, by a big, strong stud ready ta breed me ‘gain..." Applejack moaned out, squirming her hips to try and wriggle his dick just a little deeper, despite him being hilted to her core already. His flare was pressed firmly against her dilated cervix, her body all relaxed and eager to take in all his sperm once more. "...now squirt a strong, healthy foal into meh, bro. Give yer sister a baby!"

Big Mac was almost in disbelief as he heard what his sister had just said. Him and Braeburn had already pumped enough cum in her to knock up a whole herd of fertile mares, and she still wanted more. Shaking his head at the notion, he huffed, pulling out, before slamming back balls deep into his sister, hearing a muffled cry of pleasure from her as she had bit her foreleg to try and avoid waking Braeburn, before pulling out and repeating the rough thrust, again and again. Despite the ache growing in his haunches and hind legs, more with each hump, he couldn’t deny the pleasure of breeding the young mare again.

Applejack enjoyed the increasingly-rough fucking, trying to will her marehood to be wetter and tighter, squeezing down each time her stallion hilted inside her, keeping clamped down as he tried to pull back out and making it that much more pleasurable for them as he did. She groaned out as his flare once more roughly kissed her core again, feeling a mini-orgasm as he licked her sweaty neck, her vaginal muscles clamping down twice involuntarily on him as she squirted on his balls, if just a little. Her body gave her a taste of the pleasure that was to come, once she let her heat be fully satisfied the way it demanded of her; once she made her stud cum again, then let the worthy young stallion's seed take, and give her a foal.

Big Mac kept pumping his sister with all the, if fading, gusto he had left, each thrust causing his stamina to fade more and more, until he had to start resting more of his weight on Applejack’s back just to ease the strain on his wobbly back legs. Still his instincts demanded he keep going, Applejack’s scent still in his muzzle and wrapped around his brain, driving him to hilt and pull out again and again, despite how much his rump ached from his previous times’ effort.

Applejack moaned out again in a dreamy tone as that big cock kept plumbing her depths, with a desperation a colt or stallion could only get from fucking a mare or filly in heat. The urge to plant his seed, and claim her womb as his foal's vessel for the next year. It wasn’t long until Applejack felt as his flare got even bigger in her, then his cock stiffened more, his hips hiking up to hers and burying every centimeter of his dick into her tract. Once more almost ready to deliver his seed right where it was needed most again: where it most belonged.

"S-sis, Ah ain't gonna be able t' keep goin' much longer..." Big Mac admitted, feeling his orgasm welling up inside him as he flared, but also a wave of fatigue washing over him. He was never one to leave a job incomplete though, and so pressed on, getting those last strokes he needed to finish.

"H-hah...yes…do yer natural duty. Breed your sister, one last time…" Applejack whispered breathlessly, her heart pounding as she encouraged her brother, and she felt so wonderful as she felt that exquisite expansion of his flare deep inside her, as he once more started to rhythmically pulsate within her.

Her breath caught in her throat as Applejack felt his seed-heavy balls hitting her clit, and combined with his flare entering her womb itself again, that last burst of sensation set her over. Applejack covered her muzzle with her forelegs and let out a long, squealing whinny as she came, her body clamping down on his swollen cock, her uterine walls grasping his flare to keep him locked inside, her cervix clamping behind it, and the rest of her passage trying to knead the sperm from him and into her fertile, waiting womb. And it wouldn't have to wait long.

Gripping tighter around Applejack, Mac gave a particularly rough thrust in, giving a groan as his muscles protested at the overexertion with a sharp burst of pain. He'd be feeling this tomorrow, no doubt. Still, that was the last thrust he'd needed, his flare pressed firmly to the back of Applejack's womb and at its fullest as he felt that involuntary pulsing start in his pelvis again.

Her heart sung out in joy as Applejack felt a familiar warmth hit her deep inside again, each weak shot of the life-giving goo he ejaculated within her pooling with the rest, quelling the smoldering remains of her estrus' burning. "That's it, bro...gimme all ya got left."

"E-eeyup..." came the colt's weary reply.

Big Mac collapsed onto Applejack's back, his head beside hers as he pumped the last of his semen into her womb again, though it was mostly just watery squirts at this point after a couple last half-decent shots, his reserves completely dry, already having been emptied into his sister's womb before. He felt the pleasant pulsations and rush of endorphins as he once more seeded his mare, the pleasant squeezes of her canal around his cumming shaft, but under that sensation was an overwhelming fatigue, with him panting heavily as his penis once again stilled and his flare plugged up his load within his sister. He could feel that he was utterly and truly empty, having given his fertile filly every drop he had, and her taking every one, with Mac feeling some pride about that.

Applejack was breathless as she felt pleasure like never before roll through her while she took her final in-estrus creampie without protection, her whole body trembling as her orgasmic clenches started up again, albeit weaker than before. It was so much more intense, instinctively knowing she was going to get pregnant from this, that all Applejack could bring herself to do is hold still beneath him as her instincts demanded her to do and, like a good mare following those needs to be seeded and bred, Applejack accepted his last paltry load into her womb. Accepted his foal.

"I think that'll do it," Applejack said as she smiled brightly, despite, as the endorphins and breeding urges were wearing off, her pussy and belly started to ache. Not really too painfully, though, more of the ache of a job well done; a satisfying ache that told her she'd done well. She sighed in satisfaction, her soothed nethers purring with the same and her mind crystal clear. She nuzzled against her brother's cheek, giving a soft 'mmm' as she enjoyed her afterglow.

Mac felt his colthood go soft faster than ever before as it slid from his sister and back into his sheath in record time, his legs feeling like jelly and his whole haunches and hind legs screaming in pain. He'd definitely overdone it. He hoped he could still work the next day. "Y-yeah...don't think Ah'm gonna be able t' do any more fer ya tonight…an’ maybe not even tomorrow. Ah...that's all Ah got in me." Big Mac said some time later after catching his breath, with it taking all his flagging strength to haul himself off Applejack's back and onto the bed, lying there bonelessly as though Applejack’s foal-canal had sucked his very soul from him that last time.

“Awww,” Applejack said with some disappointment, but despite her mind demanding her to breed with more, and more, and more stallions - or colts - she could tell her body was pretty much done for then, and the unpleasant sensations of her estrus was a distant memory, the emptiness, the itch and burn long since replaced by the filling, soothing warmth of colt cum. It wasn’t long before she heard a quiet snoring coming from beside her, not at all surprised to see Big Mac had fallen asleep as well. After all that, she figured he’d more than earned his rest after all he'd done for her already.

She reached down and rubbed a hoof over her marehood with a soft hiss, feeling a slight stinging sensation as she touched her overused lips, though coming back with what she’d sought, smiling softly at the sight of her big bro’s colt-milk coating her hoof. Licking it off, she sighed happily as she snuggled up against Big Mac. Laying her head on him and burying her muzzle into the fur of his chest, she took in her stallion’s comforting scent, before letting her eyes flutter closed, she was oblivious to the small pinprick of pain in her belly as she’d ovulated while she’d drifted off to sleep.

As Applejack had finished her story, she looked over the room of now-aroused ponies - mares and fillies with puddles of arousal under them, and colts with full erections hanging beneath them - Applejack leaned over and gave AB a kiss on the cheek. "The next mornin’, Ah woke up to mah panties missin’ an’ Braeburn jackin’ off while sniffin’ ‘em, then led to me presentin’ to him, an’ him mountin' an' cummin' in me again. They kept breedin’ me over th’ next several days, at least three ta four times a day each colt, ‘til mah heat finally died out."

"Over th' next couple months after, though, Ah started feelin' funny; stomach-sick durin' th' mornin', bloated, hungrier by th' day. Mah lower belly kept gettin' bigger. That's when Ah realized either Big Mac or Brae-Brae had likely actually gotten me pregnant. Made perfect sense: Ah was in heat, fertile, an' likely ovulated while havin' sex so many times with 'em…takin' so much cum an' so many sperm in mah womb durin' th' deepest part of mah estrus…so it only made sense Ah'd get a foal outta it.”

Apple Bloom had known Applejack was her mother for years, and didn't really care. They acted like sisters in public, even if where she'd actually come from was fairly well-known in Ponyville. After all, it had always been fairly normal among earth ponies especially to have incestual relationships - given their powerful breeding instincts, the convenient closeness of their family members to cure their estruses or ruts with, and the fact their numbers were so limited at one point, encouraging their population increasing, no matter who bred with who - so it wasn't at all unusual to get a foal from their family either, and especially not during a filly's first, most intense heat. It was less common in modern times, given the abundance of ways to prevent an unexpected foal, but it still happened sometimes.

"Turns out Big Mac's sperm was th' one that impregnated me, accordin' to a paternity test we took, an’ probably on that first evenin' too. Unsurprisin', given how much he’d flooded mah womb compared to Braeburn’s li’l cumshots in there," Applejack said to her niece-daughter, giving her a hug and nuzzle. "As it turned out, Ah did get pregnant. Ah got you Apple Bloom, mah beautiful li'l filly." Apple Bloom smiled and kissed her mom back.

The other mares, as well as the fillies Sweetie Belle and Scootaloo, had known this for years, and were pretty nonchalant about it. The colts, however, were quite surprised at the revelation, especially Tender Taps, whose fillyfriend it was that he’d just learned that about. They all found the thought of incest, and foals being born from it, a little strange at first, but since incest and incest foals were generally accepted in most pony societies, they dismissed it as mostly-normal.

Rainbow had been rubbing herself, giving quiet little moans as she stimulated her needy pussy after such a sexy story about Applejack's first times. She was giving little whimpers of want as she rubbed her winking clit, her hoof slickly sliding over her slit, sending tingles through her body. Her unintentional show - and scent of arousal and estrus - didn't go unnoticed, especially not by the colts, their eyes locked onto that puffy, wet, deep-blue marehood being rubbed. "H-heh AJ? A little help?" Rainbow all but begged as she looked at Applejack, getting a knowing smile from the beckoned mare as she released Apple Bloom from the hug and went to her heat-buddy in her time of need.

"'Course, hun. Ah got ya. Ah’d never leave mah heat-buddy hangin’." Applejack said, approaching the deeply-needing, and blushing, mare with a sexy grin on her face.
