“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…”

And so it begins...
