Apple Bloom awoke the same way she had fallen asleep, her hooves against her big brother, as they shared his covers. The sound of morning birdsong danced in her ear before she slowly slitted her eyes open. There was something about Sundays that inspired profound laziness. Instead of cool, pale moonlight illuminating the rustic farmhouse room from the night before, there was golden sunlight in its place, warm and radiant. Bloom’s stirring caused Big Mac to stir.

Bloom sighed silently as she felt the big body in front of her move, feeling a certain comfort at the warm presence. The withers continued to move, rotating Bloom’s hooves downward as Big Mac moved. Her eyes widened and she gasped as she was squished into the mattress, the colossal farm-hoof’s body rolling squarely on top of her! Apple Bloom hollered in alarm and squirmed against her brother’s form. In seconds, she was gasping in fresh air and climbing onto her legs.

“A-a- Apple Bloom! Ah horseapples, ‘r you okay?” Big Mcintosh shouted with a start, but quickly hushed as he hovered over his little sister.

Bloom coughed as she recovered, “Koff! Koff! wh- Whoa, big b-brother! Jeez! Ah’m fine,” she spouted with a shake of the head.

With a quick inspection, hm’ing once, Big Mac nodded and patted the girl’s morning mane, “Ee-yup.” Then he turned to the door and headed down for breakfast.

Bloom turned her head as she watched him go and hopped off the big bed to follow. Mac, however, stopped her at the door, holding her with a hoof, then held his hooftip to his lips.

“Shh.”

The apple filly stopped and obeyed, letting him go first, then followed after waiting for a while. She realized it could be suspicious if they both came downstairs at the same time. Before she met the stairs, though, she trotted back to her own room to give her mane a quick brushing.

The family enjoyed a filling egg salad with toast. They all discussed their plans for the day: Granny Smith the usual lounging and weekly card night. Applejack tending the garden and inspecting the orchard, Big Mac bucking and tending the stall on the weekend shift, and Apple Bloom playing with her friends and visiting some neighbors. Everypony was in high spirits after the events of the week. They exchanged smiles as they parted, each going according to their agendas.

Apple Bloom, though, had other plans than what she spoke of. How was a small filly like her going to seduce the rock-solid Big Mcintosh? It wasn’t going to be easy, but it would be worth it in the end. The game was on!

She cantered a while toward the clubhouse, trying to throw off anypony who might have watched her leave, but after about a mile, the girl changed her course in the direction of her brother. He was in the orchard with the apple trees, of course, and she soon found him at its front end. She glanced at the growing apples, most of which were quite unripe given how early it was in the season. She knew, though, from her many farming lessons she absorbed from her brother’s and sister’s discussions, about the many different types of apples which could be harvested at different times of the year despite their normal autumn ripening. That, along with the stores of crop the family kept in cellars, helped keep their business alive and flourishing.

A.B. cantered up to her brother, trying to act casual, “Hey there, Big Mac! How’s it goin’? The apple trees doing okay?”

“Eee yup!” he replied with a prideful smile.

Bloom walked up and smiled, taking a quick glance across his body and moving her gaze on to the trees, “So I was wonderin’, you mind if I uh, y’know, shadow you today?” she heard the term in school once, in relation to cutie marks.

Mac’s expression changed immediately to suspicion.

“I mean, it’s a good time to start learnin’ with spring-time and all. I-...I promise not to get in your way. I just wanted to watch and help out, y’know? Not every day you c’n get a willin’ volunteer to help out, right?”

“Eeee…” Apple Bloom’s eyes went wide into a pout as her brother mulled over the proposition. He finally grinned, “...Yup.”

“Whoopieeee! Alright, Big Mac! I won’t let ya down! Just point me in the right direction and I’ll help with whatever ya need. Eight hooves ‘re better than four, am I right?”

The stallion simply nodded and pulled his sister into a big-hoofed, brotherly hug. Apple Bloom felt a flutter of her heart from guilt and excitement. Every time she looked at her big brother, her mind’s eye remembered his drooping phallus beneath his barrel. Every time, she imagined the size of it compared to Sun Drop’s.

Big Mac began pointing Apple Bloom around with simple one-word commands. Apple Bloom, accustomed to helping her siblings around the property, did as she was bade. She plucked apples from the ground, moved them into wooden apple buckets, moved around said buckets, and rushed back to fetch pails of water for Big Mac.

The farmgirl paused as she heard him point back towards the house and utter, “Water.”

“Huh?” This was a command she was unfamiliar with, “You need water?”

“Ee-yup. Just a pail.”

Apple Bloom trotted back to the house to fetch a pail, wondering if he was just thirsty. She returned with a simple wooden pail with the handle gripped in her teeth, filled sloshing with hose-water. Lifting his head, the stallion hooked it onto a sturdy branch above him, then he tilted the bottom of it against his snout to let the water pour out against his head and neck. His mane and neck shone in wetness, and he made a short hum of pleasure as the water soothed him from the heat and sweat. Apple Bloom watched in awe, confused and captivated at this new display. Droplets streamed down his neck and shoulders, and dripped from the ends of his mane. As the streams of water slowed, Big Mac shook himself dry.

“Thanks,” he said.

Apple Bloom picked up her jaw, “s-Sure, big brother. Let me know when you need another!” The girl never had seen him do this, and she wasn’t sure if it was really for the heat, or if there was something more going on. It was neither here nor there, though, as Big Mac continued directing her as they worked. She realized about an hour in that her brother wasn’t really ordering her as much, now that they had set up a predictable routine. The silence had gotten to be too much for her, though, so she decided to strike up some conversation.

“Hey Big Mac, you remember doing algebra in school?”

“Ee-yup,” Mac hammered his huge back hoof against a tree and there was a hail of apples.

“It’s a lot of work! Those problems get pretty long. Have you ever even done any algebra in real life?” Apple Bloom helped pick up apples and set them into the apple buckets.

“Ee-yup! Lots of apples to count, lots of apples to sell. Gotta figure in prices and sales to see how much we make,” Big Mac continued picking up apples, getting closer to his sister.

Apple Bloom purposefully turned her back toward her brother, sensing an opportunity. Butterflies invaded her gut as she swished her tail playfully. She lowered her front and raised her tail as she spoke, “Ya ever hear the joke ‘one plus one equals three?”

“Heh heh, Ee-yuhhh…” Big Macintosh's brain stopped mid-yup, interrupted by his eyes staring at his sister’s full moon. Her tail was purposefully shifted aside. Crescents defined the curves of her small ass and the smooth, shiny folds between her taut cheeks. She was obviously an unripe apple, smaller, skinnier, hardly any marely features. Then, Big Mac watched his sister’s vulva purposefully wink, and his loins stirred as those loins reminded him how extremely tight she would be. As quickly as he could, he shifted his gaze to her face, seeing a bright apple held in her teeth. She looked back at him with an unsure, wide-eyed stare. For a second, they locked eye contact with the same expression. The moment passed as Apple Bloom’s apple crushed under pressure, sending a chunk into her mouth and the rest onto the ground.

Bloom grimaced a smile, “Oops! Sorry!” She apologized and she recovered her posture.

They continued their work. Big Mac bucked and Apple Bloom picked. More and more, Apple Bloom caught her brother looking at her plot from the corners of her big eyes, and every time she did she watched his undercarriage when he turned away. It was obvious that she was getting through to him by the look of his engorged sheath.

Apple Bloom made light of their work, talking about school, her friends, her teacher, and her adventures with the CMC. She thought she shouldn’t talk about the past week, though. That would be too awkward. She did end up fetching him several more pails of water. The hulking stallion probably did not imagine that getting himself wet was doing wonders getting his sister wet, but he stopped asking for more pails after noticing her absent-mindedly itching her hind legs together while she watched him.

Finally, after a morning of apple-bucking, it was time for Big Mac to haul his yield to market. To Apple Bloom’s dismay, he denied her company with him into town.

“Last time Applejack gave up two bushels because of yer tom-foolery. Run off and look for your friends, li’l sis.”

Apple Bloom had to agree that she made a little mess of things that time she was with Applejack and she was trying to get her cutie mark. It was just as well since they wouldn’t be as alone together in the crowded marketplace as they were in the orchards. She sighed and nodded, kicking a pebble.

“Have a good day, then.”

“Eeee-yup!” Mac smiled and gave his sister a playful noogie. She giggled and shrunk away, smiling up at him and fixing her mane. Then he turned away and started off towards the market with his apple cart. She watched his plot as he went, wondering where she went wrong. It was probably biting into the apple too hard, she theorized.

Scootaloo and Sweetie Belle were not at the club-house as she expected, so she went off in search of them in their usual spots. She found them hanging around by the school house where they were bouncing a ball around. After she joined in, Scootaloo immediately asked her about last night.

“Soooooo, did anything happen yesterday? Last night?” She waggled her eyebrows.

“Yeah, did you get you-know-who to you-know-what to you?” Sweetie joined.

Apple Bloom checked for eavesdroppers, “No,” she admitted, “but I did, um, sleep in his bed last night.”

Scoots grabbed the ball, stopping the play and ensuring that all the focus was on her, “Just stop with that guilty stuff, okay Apple Bloom?” she commanded, “There’s no reason to be nervous around us, especially after what we’ve all been through together.” The girl looked from side to side, though, just to be safe, then looked her friend straight in the eye, “Just say it: ‘I want to have sex with my brother!’”

Apple Bloom smirked despite her blush, and she glanced at Sweetie, who was looking slightly perplexed.

“Say it Apple Bloom!” Scoots ordered.

“a-Ah-”

“Say it fast and sure!”

“I want to have sex with my brother! Hehe!” Apple Bloom couldn’t help her giggling, bringing out playful laughs from her friends. Satisfied, Scootaloo returned to bouncing the ball around, friend-to-friend.

“So you just slept?” She asked.

“Yeah, he just told me to go to sleep. But then this morning! I showed off my butt to him while I was facing away and I’m pretty sure he was staring at my pussy!”

Sweetie gasped, “Oh! That’s a good sign!”

Apple Bloom returned home at the end of the day, having spent it playing with the CMC. Sweetie suggested they try their hooves at bead-working, but Scootaloo stuck her tongue out at that and she left for home, Apple Bloom soon after.

The filly enjoyed a relaxing dinner with her family. While she ate, it seemed like everypony was in good spirits and satisfied with their day, and it felt to her like if things could go back to normal so easily, maybe she should too. It really was too much to ask of her brother, and besides he already had Applejack. The last thought was held with some bitterness, but Apple Bloom knew it wasn’t right to be envious. Maybe, though, sometime in the future. Someday…

Apple Bloom stirred awake. Was it her imagination, or was that a creak from her door opening? As she opened her eyes, she heard hoofsteps through the door and a darling southern mare’s accent floated to her ears.

“Apple Bloom,” it sang, inviting her to awaken.

“Huh? Applejack?” She then realized there were hoofsteps for two. She lifted her head, fully awake now, and she saw her brother as well, “And Big Mac? What’s going on?” Apple Bloom asked, bewildered.

Sturdy Applejack leapt onto the bed, surprising her sister. She snuggled her affectionately and giggled, “Is my tramp of a little sister tryin’ to seduce her brother away from me?”

Apple Bloom whooped at the surprise snuggle, then she blushed at the question, quite evidently when Big Mac lit the nightstand lamp.

Big Mac took one look at his youngest sister’s flustered expression and he couldn't help but smirk at her ‘uh’-ing and ‘um’-ing.

“Eee-yup,” the tall young stallion definitively finished for her.

Applejack stroked her sister’s mane to calm her down, “Aww, now don't you worry none, sugarcube, it's alright,” she stopped herself to collect her thoughts, “I mean, after the past week I can understand that you'd be curious. Especially after already seein’ Big Mac’s namesake two times now? One of them bein’ when I was handlin’ it, right?”

Apple Bloom saw Big Mac scoot up behind AJ and give his sister a hearty hoofslap to her plot, making AJ let out a cute whinney in alarm. Her little heart was racing as her brother and sister carried on in a way she had never seen, and spoke of these new things just casually.

“AJ, you... but I thought… I thought these things were supposed to stay between two ponies that loved each other a lot and got married and were supposed to have foals an never leave each other an were old ‘nuff an an an not...” she looked down, as if she should be ashamed for bringing this stuff up. Especially since they were all, “brothers and sisters?”

AJ and Big Mac exchanged looks, then they looked down, “Yer right, sugarcube, “said Applejack, “I don't really know how it started, but when ya think about it, we were two ponies, filly and colt, alone on a farm with our parents gone and a grandma and a foal to care for. Not to mention a big farm to look after. I think we just got stressed out and, ya know... needy. Not like last week kinda needy, heh no, just regular needy--”

“You two were doing it for that long?!” Apple Bloom interrupted, “I thought it was just last Monday!” All three fell silent a short moment, until Bloom continued,”b-But what about, you know,” AB, sitting up in bed now, gave her tummy a rub.

“Oh that? We weren't that dumb o’ course. By combinin’ our allowances we were able to get some contraceptive potions.

“But anyway," AJ tried to downplay her oversharing, "speakin’a last week, maybe ya’ll should tell us about yours. Leavin’ out Monday night o’course. We already know about that part.”

Apple Bloom started with a blush with her memories of her time with the CMC. AJ winced as she heard about the perversion of Miss Cheerilee, she struggled with her anger hearing about Twilight’s out-of-control plant, blushed as she heard of the three girls experimentations, smiled as she heard about Sun Burst, blushed again as she was told of their foursome, and cheered with a whoop as she heard of their mission to the hermit couple's home. Bloom decided that the incident with Scootaloo should be left for Scootaloo to tell.

Big Mac sat open-legged across from them on the floor sharing AJ’s reactions for the most part, but Apple Bloom would often get distracted as she saw the reactions of Big Mac’s penis to parts of her story. She watched it get big and soft as she spoke, basically in response to the steamy parts. If there was a long section of story between sexual events, it retreated back into its sheath, softened. By the end of the story, she was looking over at him as she started into a sexual part. She giggled as she watched him harden quickly when she started talking about the time with Scootaloo, Sun Burst, and Sweetie Belle. It was almost like a game for her, and her lips curled up into a giddy grin as she played.

“I think he liked it, Apple Bloom,” Applejack said, matter-of-factly.

The little sister giggled, “Mac, did you sit there on purpose?”

Big Mac nodded and said, “Yup ma’am.” The stallion's cock once again started to press out of his sheath.

“You wanna stick that big cock in Applejack?” She asked, the words sounding extra taboo coming from the youngest sister’s little voice.

Big Mac grinned wide and chuckled, embarrassment in his voice as he heard his precious sister speak with such words, but his cock sprang up hard at them, “Eeeyup ma’am!”

Without skipping a beat, the big pony rose up and walked to the bed. With both his sisters beneath him, he hefted his body onto the bed straddling them.

Applejack moved into a receptive position as her brother approached, “Oh my, I think you lit the fires young’un,” she smiled at her sister, “c’mere an’ scoot yer li’l plot under me.”

Bloom’s body was on fire and her heart pounded in her chest. She laid down on her back and spread her legs for her sister, revealing how sopping wet she had gotten during her story.

“Hooo Sister! You look how I feel. Now, how ‘bout you do yer sister a favor and tell him to stick me with that big cock, heheh!”

Bloom smirked and grinned, her neck fur prickling as she gazed at her siblings and finally gave the order, “b-Big Mac, stick that big cock in my sister!”

Apple Bloom felt a wave of elation watching the coupling of her sister and brother together. She moaned out a sigh as she watched them entwined, slack-jawed, in the pleasure of their sex. She was already hoofing herself. They whispered words of their pleasures. Apple Bloom saw in Applejack’s face when Mac hilted inside her, making the two shiver at the feeling. Then Big Mac started moving, rocking the bed frame slightly. Apple Bloom heard it creak under the swaying motion, and with it she heard the wetness sliding between her siblings’ bodies.

As the tension grew, they felt more comfortable sharing their voices. Bloom could hear how good AJ was feeling, making her own pussy feel even better! She let them both know with her own voice, her young, little voice moaning and squealing.

AJ bit her lower lip, and spoke between breaths, “b-Big Mac...our li’l sis… watchin’ us fuck… and cloppin’ to it right in front of me!” The young mare moaned loud as her climax started, her hot canal gripping and milking her brother for his cum!

Apple Bloom could feel the climax in her sister. She sucked in a gasp and yelled in her lust, “Fuck! Fuck my sister! Fuck her hard and cum in her!” Her pussy twitched against her hoof, energetically milking a shaft that wasn’t there.

Big Mcintosh’s voice rumbled a needy growl as his hips pounded away like they have so many times in the past against his sister’s strong ass, but his climax reared up much sooner as his ears picked lapped up the sound of his youngest sister cheering him on! His tip flared, and the draft pony made a great, long moan in his pleasure. His moan became a suppressed roar as he began unloading hefty threads of his seed into their rightful place: deep into the deepest depths of his younger sister! His lover milked out every last drop as he pressed his hips firmly against her, dutifully offering his essence in full.

The siblings huffed and puffed in afterglow. The youthful equines squirmed as their pleasure-soaked minds started returning to the world. Slack-jawed and panting with her brows lifted up, Applejack looked down at her pretty, red-headed little sister. She grinded back against Big Mac as his tool filled her with everything it could offer, closing her eyes again. She flinched as an unexpected little hoof pressed in against her belly and explored from the outside where that flaring tip and its seed would be.

Apple Bloom bit her lower lip as she explored, her hoof slick with her own emissions, and she pressed it firmly against her sister's belly and nether region. Her hoof grazed against her sister's more-developed teets, and even brushed up against her slit. She let out a breath she didn't know she was holding, and she asked with a quiet, pleading tone, "Sis, I wanna try out Big Mac too. 'sthat okay?"

"Heh," Applejack smiled wide, "Thought you'd never ask, sugercube. But you better be ready for a ride, this apple bucker is bigger'n your average colt. I'm wonderin' how much of him y'all can even fit, t'be perfectly honest," With a wet sound and an easy balancing act, A.J. scooted out from under her brother, then the mare was off the bed and hovering over her younger sister. Big Mac shifted his weight to help.

At long last, Apple Bloom knew that there was nothing left between herself and the impressive, red form of her big brother. She peered downward and a light gasp escaped her lips. There between his legs drooped his massive tree-trunk-like penis, engorged in post-coital swollenness. The veiny surface was slick with the mixture of its semen and Applejack's juices. Her sister's words hung in her mind as she gazed on it, this being the first time taking in the sight of a fully-grown, larger-than-average male spire like this.

"Alright sweetie, turn yourself around so it'll go in easier. I think I was able to take off the full force of his passion, so I think he'll be able to take it easy on you-"

"Big Mac, I want you to fuck me! Fuck me like AJ! I want you to do me hard! I want you in me so bad! I've been waiting all week for this!"

Unseen by Apple Bloom, Mac and A.J. exchanged blushed glances. Applejack said, "Well you heard the little lady, Big Mac!"

"Eeee yup!"

Apple Bloom was, despite all she had gone through to arrive at this point, still surprised by her words. There was no more time to think on it, though. The mattress rocked as her brother closed in around her, engulfing her, becoming her world. She suppressed the urge to look back. Instead she tensed and closed her eyes, as if she was about to jump into a cold lake all at once. Big Macintosh brushed himself up against her body. His wet shaft caressed her raised haunches, only triggering her brain to raise them even more. She could even feel it harden as he pressed it up against her entrance and spread her blushing lips apart.

Big Macintosh purred. His rumbling voice penetrated the core and his breath washed against the filly's ear, “Yer in fer a ride, li’l filly. I’m gonna fuck you wild! I’ll make you a mare alright, just like your sis. Just let Big Mac take care of it.”

Apple Bloom rocked her hips back and forth in anticipation and the hairs on the back of her neck stood on end. Everypony knew that the occasional sentences Big Macintosh made were indeed quite the occasion. As he spoke she could feel him becoming fully erect, and then she could feel his tip pressing against her entrance. Her lips parted wider, and wider, and wider, and wider still! AB shut her eyes fast as the strain took its toll on her small body. She pushed back on him more and more as she widened for him, wanting herself to be full of him, needing herself to be screwed mercilessly, and knowing that he wanted to be inside her just as much!

There was a popping feeling!

“AH! Big Mac!”

The first bits were inside! AB could feel Big Mac’s cock taking up quite a bit of space just with his tip inside her. It was distressing for her to think that he wouldn’t be able to fit himself fully inside, but it was something she had already imagined. After all, she was still growing, and she took comfort in the fact that her smallness wouldn’t always be.

Apple Bloom gasped as her sibling probed his length deeper inside. Her walls squeezed and massaged instinctually, and they gripped that member Apple-family hard! AB’s mind was numbing, her thoughts a-whirl. Her world was once-again becoming solely her body, his body, and pushing back against him.

Against her deepest parts, the giant stallion was able to reach not even a half of his usable length. He huffed, almost impatient, “NNnnnngth! Daaamn, filly!”

AB replied, eyes flicking open, “fuh-Fuck me!”

The stallion didn’t need telling twice. Before the words finished leaving the girl’s lips, Mac’s hips were moving. All-the-better too, the more he moved it seemed the easier things went. Apple Bloom’s immature voice echoed through the room as she sighed and panted, mixed with the baritone grunts of her older brother’s. The rhythmic sounds of sex once again arose.

Off-rhythm, though, was Applejack who gazed in amazement at the pair, and had started to hoof herself off. She smiled as she watched the familiar look of concentration take root on the faces of her brother and precious little sister. It was a sight to behold. Her own body was not as big as her brother’s, but with her muscles and stature she did come close. Her little sister, though, was less than half his size, and that clearly showed now! At the end of the bed, AJ had a perfect view of the union between bodies. With how he was pounding away and how Apple Bloom lifted her body to him, she could see her little belly being pushed out from the inside! She could even hear her sister’s breaths matching the pace of those powerful thrusts, and she couldn’t help but match that pace with her own hoofjob. A part if her wished to be that small again, if only to feel that intensity!

Nopony could speak. The heat rose and rose, the passion doubling. Breaths came shorter. Big Mac had shifted his position and he held his lover tight in his fore-hooves. Little Apple Bloom shoved her body backwards against him with all the strength she could muster, as if her very survival depended on doing so. She arched her back and her body convulsed in waves as her tail root brushed up with Big Mac’s underside. The convulsions spurred on her orgasm, which overwhelmed her body into a spasming mess. Big Mac doubled his speed again as the tiny body under him started to cum around his pre-flaring cock!

Big Macintosh howled in ecstasy as his orgasm took his mind! Apple Bloom and Applejack moaned along with him! His hips jolted the last of his thrusts as the first of many waves of seed shot forth! AB felt something warm and wet erupt within her body, and she felt something else warm and wet tugging against her mane, realizing that her brother was grasping it in his teeth! Big Mac continued to nibble, then kissed her neck. The kissing became aggressive nuzzling, his breath plentiful against her upper spine.

She felt hot. She felt full. She felt wonderfully exhausted.

When she awoke in the morning, Apple Bloom was smiling. Smiling as if waking from a very good dream.

The dream had monsters, heroes, and villains. In the end, the heroine got her prince, and she got to share him with her sister forever. The end.

Apple Bloom heard her sister call her, as if for the second time, “Apple Bloom it’s time for school, sugarcube!” Hoof-clops came from the hallway towards her door. Apple Bloom pressed her hoof to her belly and noticed she had this strange feeling of fullness there, even though she was hungry for breakfast. She checked with her hoof, drawing it against her nether region and taking a sniff. She smiled to sense her brother’s scent.

Apple Bloom saw her door crack open and Applejack lean against the frame, “Alright, hun, I know yer really hot stuff, but ya still gotta get that ass to school. Ya want some breakfast?”

Author's Note

Some people write slow, okay? That being said, I apologize to those who waited. I have had a terrible work ethic about this, but I stubbornly did not change the status from "incomplete" to "cancelled".
The joke is on you all, though, I had to wait since 2012 to see this complete! That's the year my google doc was created! It's probably really clear that my writing style has improved since then haha. I also struggled with tone, you could probably guess, and you might guess that that's why it took so long for me to give you all chapter 4.

In the end, I pushed myself to finish, and now I can finally feel the itch of this unfinished story satisfied. Sorry for the clichés and sorry for getting so serious in tone, but thank you for reading and thanks to everyone who has commented and favorited! Now go out into the world and enjoy your lives :)
