Chapter 1

The late summer sun was shining bright over the fields of Sweet Apple Acres; the trees dotted as far as the eye could see by dozens of brilliantly red apples. It was going to be a bountiful harvest this year as one pony out amongst the trees could assure. Big Macintosh Apple had already spent an entire day neglecting most of his chores so that he could get ahead on the bucking and even then he had barely made a dent on what they needed ready to ship by the weekend. With only four more days until shipping day, he was going to have to work his tail off to meet the farm’s quota.

As he strapped himself into the wagon bearing the literal fruits of his day’s labor, he mused that things would be much easier if the farm’s only other full-time worker, his co-owner and sister, Applejack, were there. Even if he still had to do all the bucking on his own, they could at least divide the labor so that everything else didn’t fall to pieces before Applebucking Season was over.

But as he made his way towards the creaky old barn where they stored the harvests, he knew that he could wish for things to be different until the cows came home and that wouldn’t make them so. All he could do was keep working as hard as he could until Applejack came back from saving Equestria again for the…

He hummed to himself, realizing he’d lost count of how many times his little sister had saved the world. The same little sister that he’d read bedtime stories to and cleaned up after. And now she was fighting ancient magical monsters the likes of which he couldn’t even comprehend while he tended to a bunch of land.

How the time flew.

But he had long since made peace with his role in the Apple Family. Somepony had to keep the farm running smoothly so that they’d have the bits to keep the pantry stocked with food and a roof over their heads. Even if he had to buck the apples on his own. And sell them. And repair the roof that always seemed to have a new hole right when he finished fixing an old one. Life on the farm never stopped, it seemed, and there was always something that needed doing.

Just like right now the day’s harvest needed sorting! Drawing the wagon into the barn, he unbuckled himself and pulled up a stool and a number of empty barrels, into which he began tossing the apples one by one based on where they needed to go. One bushel each went to many of the various restaurants and eateries around the town, half a dozen more to Barnyard Bargains, a local retailer, and a dozen more for the wholesalers throughout Equestria they provided. Granted, he hadn’t picked enough today alone to meet all that, but he’d put a good dent in the local orders at least.

He was lost in the dull tedium of the task to the point that he almost didn’t hear the barn door open. A butter-yellow filly trudged in, looking like she was carrying the weight of the world on her back. With a world-weary sigh, she made her way over and flopped down next to him.

The big red stallion reached down to pat the top of his little sister’s head even as he continued to work. “Bad day?” he asked, his voice a deep, gentle rumble.

The little filly gave a sigh worthy of a full-grown mare and nodded as much as she could with her chin flat on the hay-covered floor. “Yeah… I didn’t understand Ms. Cheerilee’s lesson today. And when I tried to stay after class to ask her about it, she shooed me out the door before I’d even opened my mouth!”

Now Big Macintosh Apple was fairly certain he knew Ms. Cheerilee pretty well. They’d spent more than a little time together and he’d even go so far as to say they were friends. And if there was anything he knew about the mulberry-coated mare, it was that she was one of the kindest, most patient ponies he’d ever had the fortune to know. There was also no pony in town that cared more about the schoolfoals getting a solid, well-rounded education than she. He couldn’t imagine her sending away a student seeking knowledge for any reason.

“That don’t sound like her at all,” he said. “What was the lesson?”

“Where babies come from.”

The apple Mac had been trying to toss into a barrel flew from his mouth and rolled across the floor until it stopped against the far wall. He hazarded a glance down to his little sister, innocently lying belly-down on the floor with her big cheery bow even drooping a little and wondered if he had heard her wrong.

“W-what now?”

“Where babies come from!” Apple Bloom said in a huff as she rolled onto her back to look up at her brother. “I didn’t understand any of it! Well, I get that fillies and colts have different parts under their tails—”

It was at that moment that Mac knew he was in for a trip.

Apple Bloom continued, completely oblivious to her brother’s suffering. “But I didn’t get anything else! She was talkin’ about how only a mommy an’ a daddy can make a baby, but that’s not true cuz then how could AJ and Rarity have had one? An’ she said that the colt puts his thingy in the filly’s parts and I don’t know how that works at all! How do you put anything in a filly’s parts? Where do you put it? An’ how do you put a colt’s floppy thing anywhere?! It just don’t make sense, Mac!”

She flopped all four of her legs out to the side like she was giving up on the world. “And I tried to tell her I didn’t understand! I did! But she just said she had to go and shoved me out the door! What if there’s a test on where babies come from and I fail it?! AJ said I’d get a spankin’ if I failed another test!”

Suddenly she gasped. She bolted upright and scrabbled up to Mac, placing her forehooves on his thigh and looking up at him with wide, pleading eyes. “Please Mac! You were a colt once, right?! Ya gotta teach me! I don’t want a spankin’!”

Once the shock of the situation wore off, a sly grin broke across Mac’s face. He and Applejack had often wondered when they’d have to have this conversation, and the moment was finally here. Pity that his sister had to be away; she’d be disappointed to find she’d missed it when she got back.

Memories from years ago flooded his mind. He was fourteen; Applejack was twelve. She had come to him with similar questions, assuming it’d be easier to talk with somepony closer to their own age than their grandmother, Granny Smith. And together, they had taught each other quite a bit about the subject. Now, it seemed it was time to impart this knowledge to his other little sister.

“Alright, alright, Sugarcube; ain’t nothin’ to worry ‘bout!” he said, ruffling her cherry-red mane lovingly. “It’s all a lot easier’n it sounds. How ‘bout ya help me finish up sortin’ these apples an’ I’ll teach ya everythin’ ya need to know?”

With a joyful cheer, Apple Bloom threw herself into the sorting. So overeager was she that Mac had to spend more time corralling her than sort himself. But between the two of them they were able to make record time on the remaining harvest and before they knew it Mac was shutting the door to Apple Bloom’s bedroom behind them.

Apple Bloom scampered in happy little circles around him as they made for her four-poster bed, the one he had helped their Pa make before she was even born, and hopped on top of the peach-colored comforter with its swooping pink stitching and little embroidered apples.

“So where’re we gonna start, Big Mac?!” Apple Bloom asked in a rush as she took a seat facing him.

“Well,” he replied, pretending to think as he stroked his chin. “I suppose ‘for you can learn where little foals come from, ya gotta learn the difference between colt and filly parts and how they both work.”

“But I already know the difference! I’m not a baby!” Apple Bloom whined, sticking her lower lip out in a pout. “Colts have a wiener and balls and fillies have a hoo-haw!”

Mac smiled at the cute terms and how matter-of-factly she’d said them even as he knew he’d have to correct her. “Well, that’s true. But you need to learn the real names for ‘em, and I’d be willing to bet there’s some stuff you don’t know ‘bout ‘em, too.”

“Like what?”

Mac leaned back and spread his hindlegs. The sight instantly captured Apple Bloom’s attention. “How ‘bout we start with colt parts. Now, like ya said, colts have a wiener and two balls,” he said, nudging each with a hoof in turn. He felt a small swell of pride as Apple Bloom’s eyes followed his every move. “The balls are called testicles, and the sack of skin they’re in is called the scrotum. It’s inside the testicles that the semen’s made. You know what that is?”

Apple Bloom shook her head distractedly, her eyes still locked on his balls. Just for fun, he slightly jostled them back and forth, watching in amusement as his sister’s eyes moved side to side to match.

“Well, we’ll get to that in a minute then. D’ya want to take a closer look?”

This time Apple Bloom nodded fervently and crept closer like his balls were small critters she might scare off. She continued until her nose was only inches away, and he could feel her every breath across his skin. Tentatively, her hoof began to reach out, but it held up just short of making contact.

“Can I…?” she asked in barely above a whisper.

At his nod, her hoof went the rest of the way and just barely nudged his skin. Seemingly deciding she hadn’t broken anything, she went in again, this time just pushing the skin around and feeling his ball slide underneath. She even pushed in a bit, feeling the give of his pliant flesh.

She let out a giggle. “It’s kinda squishy!” She poked him again to demonstrate.

With the continued sensations of somepony other than himself, the inevitable finally happened. The tingling in his dormant member grew too great and, with a twitch, it began to slide out of its sheath. As fascinated with his balls as she was, it took Apple Bloom a moment to notice, and by then the entirety of his head was out in the open air.

“Your wiener’s growin’!” she exclaimed.

Mac nodded. “It’s called a ‘penis.’ But yes, it is. And d’ya know why?”

“Penis…” she mumbled before snapping out of her stupor and shaking her head. “Nuh-uh. I’ve only ever seen it long after ya get out of the bath. I thought it was just when it got wet.”

“Well, not exactly,” he said. “It can happen when it feels somthin’ real nice, like the warm water of a bath or a nice pair of hooves like right now.” –He winked– “Or it can happen when a colt looks at a cute li’l filly, also like right now.”

Apple Bloom gave the most adorable little grin and blushed as she reached up to fiddle with a lock of her mane.

Mac gestured down toward his still-lengthening stallionhood and said, “Well go on, give it a good feel, too. Y’might see it do something else you’ve never seen before!”

“Something else?!” she asked. Her hooves shot out like she was racing her big sister to the last of the flapjacks at breakfast and wrapped around the head of his dick.

“Oof! Gentle there, Sugarcube,” Mac gently admonished.

“Heh, sorry, Big Mac,” Apple Bloom said, giving a chagrinned smile.

Her iron grip lessened to a more normal touch, and Mac let out a long, contented breath. Her hooves were soft as could be, untainted by years of fieldwork like his own or even Applejack’s. Even the hard walls were filed to a perfect bevel, allowing them to glide across his skin without the slightest discomfort. The frogs of her hooves were as cushioned and smooth as a newborn babe’s.

It was no surprise then that his stallionhood continued to grow until it was completely out of its sheath. Even flaccid, it was nearly half as long as one of Apple Bloom’s legs. She giggled as she batted it back and forth, watching it flop around. But when she let go and it managed to almost stand upright on its own, she looked puzzled.

“Your penis is getting harder! Why’s it doin’ that?” she asked.

Mac was finding it harder to focus on the lesson through the growing haze of arousal plaguing his mind. “Umm, f-for the same reason it started growin’ in the first place. And also so it can get ready for sex. Do you know what that is?”

“Nuh-uh.”

“That’s the part Ms. Cheerilee was talkin’ about putting the colt’s parts in the filly’s parts. When two ponies do that, it’s called ‘havin’ sex.’

“But how do ponies do that?!” Apple Bloom asked, her temper at not understanding returning. “Where do you put it in the filly parts? There’s nowhere for it to go!”

“Of course there is, Sugarcube! Ain’t you ever taken a good look at yourself? There’s a hole it goes in down there.”

“A hole?!” Apple Bloom shouted. In an instant she was lying on her back with her own hindlegs spread, Mac’s body all but forgotten as she frantically looked herself over. “Where?! The only hole down there’s my tailhole; you don’t mean that one, do ya?!”

“No, no, not that one, Sugarcube. Slow down, now,” Mac said, trying and failing to hold back his laughter at her naiveté. “Here, I’ll show you. May I?” he asked, gesturing towards her. After a second’s deliberation, she nodded him on. Pointing to her tailhole, he said, “While we’re at it, this is called your ‘anus.’ And no, that’s not where the penis usually goes, though it can if ya want it to—”

“I don’t!” Apple Bloom yelled.

“But normally,” he said, using his tone to tell her he didn’t appreciate being interrupted, “you use a hole called the ‘vagina.’ I’ll show ya; gimme your hooves.” She reached down between her legs and he helped her place one hoof on either side of her fillyhood. “Now you just pull outward a little bit.”

Then, like a treasure chest opening before him, he watched as his baby sister spread herself apart. Her yellow coat gave way to the hottest of hot pink skin that was already glistening from the traces of wetness leaking out. A small nub, barely bigger than an apple seed, sat at the top, occasionally bobbing in what would have been a wink had she not been holding herself open. And there, dead in the center like a work of art on display, was her entrance.

Mac pointed to it, hovering his hoof less than an inch from touching her. Even from that distance he could feel heat rolling off of her. “That is what I’m talking about. It’s called the ‘vagina.’ That’s where the colt puts his penis during sex.”

“H-how does that big ol’ thing even fit in there?” Apple Bloom asked quietly, suddenly sounding breathless.

“Fillies are surprisingly stretchy down there, don’t you worry none. And y’see how it’s kinda wet?”

“It is?!” Apple Bloom yelped, curling upon herself even more to get a closer look. “I didn’t pee, did I?!”

Mac chuckled. “Naw, Sugarcube, that ain’t pee. It’s a special lubrication your vagina makes to help a colt’s penis go in. It’s what your body does to help you get ready for sex, just like how my penis got all bigger. Understand?”

“Umm, I th-think so…” Apple Bloom muttered, sounding unsure if she really believed him. “But once the colt puts his thingy– I mean, penis, in the filly’s v-vagina, what then? What happens next?”

Mac opened his mouth to tell her when another idea came to him, likely brought to mind by the nagging feeling radiating from his stallionhood that demanded to start receiving attention again. “Well, I could tell you,” he said, smiling deviously and he leaned in close to her still-spread fillyhood, where he blew across her exposed skin, causing her to shiver. “Or I could show you.”

“Show me…?” Apple Bloom said in a daze. Mac could tell she was even more lost to her desires than he was. “A-alright! What do I do?!”

Mac reached past her to stack her pillows and gestured for her to lie upon them, which she did on her stomach. Whether or not she was doing it intentionally Mac couldn’t be sure, but she already had her tail pulled to the side so that it was out of the way, leaving her fillyhood still on display just for him.

The small yellow rump before him cut a nice image that he couldn’t help but admire. The round lumps of her haunches still had plenty of baby fat on them, leaving them looking soft and perfectly cushioned for the pounding they were about to receive. He could remember back when AJ’s tailend still looked like that, back before she started working the fields like he did. Sure, the muscled posterior she had now was enticing in its own way, but he couldn’t deny he missed how soft and inviting she used to look.

When Apple Bloom let out an impatient grunt, Mac realized he was staring and snapped out of it. Hauling himself to his hooves, he moved to stand over her, his massive body dwarfing her own. His stallionhood, now at its full, proud length, slid over the base of her tail and down her back. He shuffled his hips back, dragging his member down between her tail and haunch, relishing the give of her delicate curves until his head suddenly came to rest somewhere moist and pleasantly warm.

“Alright, Sugarcube,” he mumbled through the anticipation flooding him. “First, the colt puts his penis inside the filly’s vagina.”

Afraid of hurting her with his tremendous strength, he didn’t dare try to force himself inside her. Instead, he merely leaned forward. Just a hair; just enough that his own weight drew him forward and the first fraction of an inch of his stallionhood slid inside. Even that small minutia of her waiting depths felt like heaven. Now Mac had been around in his time, having experienced the pleasures of a few mares around town, but none of them compared to the luscious peach of a nubile young filly like Apple Bloom was, untouched and unspoiled as they were. It was only in that moment that he realized how much he had missed those early days he and Applejack had shared.

Leaning forward once again, he continued until the head of his dick came to rest inside. Already he could feel Apple Bloom’s walls struggling to fit his girth inside. They pulled and pushed in a never-ending rhythm that already sent tingly ripples down his length.

“Ugh…” Apple Bloom huffed. “Big…”

“Are you okay?” Mac asked, for the first time feeling concerned. “Does it hurt?”

“Mm-mm, it feels good!” Apple Bloom said dreamily. Mac leaned forward to get a better look at her face, only to see her making the biggest, dopiest grin he’d ever seen on her. “It’s really good! It’s better than… than… anythin’!”

Mac smirked confidently. “You haven’t felt anything yet!”

Feeling emboldened at what he saw as a success, Mac didn’t see the need to be as gentle any longer and, with a single, drawn-out motion, he pushed himself the rest of the way inside until his tip came to rest against the end of her passage. Instantly her walls locked down around him in a vice-grip, like she was afraid that if he so much as twitched he’d pull out and never come back. It took a surprising amount of strength to overpower the little filly and slide himself back so that he could thrust in again. All the while, her slick insides undulated around him, threatening to overload his mind with the rush of bliss they brought on.

He leaned down to nibble at her ear and at the same time buried his nose into the perky bush of her mane. He breathed deep the spicy-sweet scent of filly. Like a wild red delicious plucked straight from the vine and dipped in sweet ambrosia.

“Mmmm! More, more!” Apple Bloom cheered. She was wriggling non-stop underneath him upon her perch of pillows, stretching each of her legs in turn, squirming from side to side, all the while beaming like she was having the time of her life. “Go faster, Big Mac!”

“Can do, Sugarcube,” Mac said, chuckling.

He picked up the pace with every thrust until his dick was like a piston firing inside her, his hips colliding against her haunches with audible slaps. Each time, his balls collided against her clit and she let out an adorable gasp. Soon the room was lost to wet schlick-schlicks and both high and low pitched moans.

After a particularly hard thrust, Mac was pleased to find that even Apple Bloom’s orgasms were cute. At once, she constricted down on him, pinning him in place as she wailed out an ear-splitting squeal. It lasted all of a few seconds before the pressure let up around his member and he went right back to his rhythm like nothing had happened. The lack of a break had Apple Bloom going again after only a few seconds until she came again, even harder than the first time.

Over and over it happened. She’d hold him in place, scream and he’d go right back to pounding her again. By the time he felt the familiar tingling deep down in his balls, he’d lost count of how many times she’d cum.

“O-okay, Sugarcube,” he stammered, still wildly slamming into her overstimulated fillyhood. “I’m… about to… orgasm!”

Even before he got the words out the dam broke. He could feel every ounce of every gooey white rope spewing forth from his tip with all the force of a firehose. Every throb filled her more and more, the pressure growing as her far-too-small womb ran more and more out of space. The ocean of stallion spooge continued to build up in front of and then around his member until finally it burst out of her fillyhood and all over both of their crotches. And even still he kept spilling more into her until the last drop dribbled out of his tip and a veritable pool spread out on the bed beneath them.

Apple Bloom was a giggling, panting mess as Mac pulled out of her. His dick came out like the cork on a champagne bottle, complete with the waterfall of fluids that followed afterward. Ignoring the massive mess that would need to be cleaned eventually, he lay down next to her and helped her roll onto her side to face him.

She was still grinning stupidly and laughing under her breath. “Hehe, Big Mac… hahah, that was... the best thing... ever!”

Mac chuckled at her punch-drunk expression. “Well, I’m glad, Sugarcube. That’s ezzactly what sex’s s’posed to be like. A whole lot of fun an’ good feelin’s! So… how’d ya like your demonstration? Got any questions?” he asked, remembering he was supposed to be teaching her.

“Ummm…. Uh…” she muttered, still tittering under her breath even as her eyelids began to flutter with the beginnings of sleep. “Oh yeah! Where do babies come from?”

A moment passed before Mac realized he had never even gotten to the point of what the conversation had been about in the first place and he burst out laughing. By the time he pulled himself together enough to begin answering her question, he looked over to find her fast asleep and snoring softly. He shrugged; they could always finish the rest of the lesson after she’d rested.

Not wanting to disturb her, he grabbed a small blanket out of the wardrobe to drape over her, figuring the mess could wait until later as well. The last thing he did was place a gentle kiss on the top of her head before turning off the light. “G’night, little sis. Love ya.”
