“Come on, Mac, you heard Filthy! He was going to cut ties with the farm!”

Applejack and Big Macintosh were walking down the dirt path back towards Sweet Apple Acres, Celestia’s sun hanging high overhead as appletree after appletree passed them on either side. Their trip to Barnyard Bargains hadn’t exactly gone to plan; Instead of going in and telling Filthy that he wouldn’t be getting any cider to sell, Applejack had kinda-sorta fibbed about Granny being real, real sick, leading to one big brother who was rather disappointed in his younger sister.

Big Mac turned towards said sister and frowned. “That don’t give you the right to go around lyin’ like that! We both know that Granny ain’t sick, and when Mr. Rich finds out he’s goin’ to be mighty angry with ya! Hay, Granny’s gonna be mad, too, especially once ah tell her what you said!”

Applejack rounded on her brother with wide, fear-filled eyes. “No! You can’t tell Granny! She won’t even think about lettin’ me run the farm if she knew!” She sat back and placed both her hooves on his broad shoulders as if she was holding on to him for dear life. “Ya just can’t! I’ll do anything, just don’t go tellin’ Granny!”

Something clicked at the back of Big Mac’s mind as soon as the word ‘anything’ slipped past his sister’s lips and wormed its way into his ears. “Wait… Anything?”

Applejack furiously nodded her head. “Yeah, didn’t ya hear me? Anything! Just don’t go blabbin’ to Granny yet!”

For once in his young life, Big Mac was at a loss for words. Idea after idea popped into his head about what Applejack could do for him; She could do his chores for a week, she could clean up his room for him, she could wash his favorite yoke…

But it was what the young, hormone-driven side of his brain came up with that truly gave him pause.

He looked up. There, just a short walk away, was the large, red barn of Sweet Apple Acres. A barn that he knew was currently uninhabited, what with Granny surely making her Equestria-famous salad in the main house’s kitchen right about now. In fact, chances were that nopony would stop by the barn for at least the next half-hour or so…

Big Mac looked down at his sister’s wide, puppy-dog eyes as a tightness formed between his legs, the same kind of strange feeling he’d get whenever the wind blew a mare’s tail to the side to show off the voluptuous pair of lips just underneath. “You did say you’d do anything, right?”

Applejack threw up her hooves in frustration. “Yes! I said anything!” She crossed her hooves and looked up at him with a scowl. “What, do you want me to do your side of the orchard or somethin’? Cause I’ll do it!”

Glancing back up at the barn and then back down at his sister, Big Mac blushed and, feeling Little Mac start to stir underneath him, slowly shook his head. “Nah, I got a better idea…” He stepped around Applejack and, after taking a quick peek down at the smooth curves of her rump, resumed his leisurely pace towards Sweet Apple Acres. “Let’s head on up to the barn. I’ll, uh... fill you in there…”

Applejack sighed and picked herself up. “Fine, fine… Lead the way…” She kept her eyes downcast the entire trip to the barn, never noticing the slowly stiffening shaft swaying between her older brother’s legs…

With a loud creak and a heavy thump, Big Macintosh closed the barn doors behind him and his sister and turned towards a large stack of hay bales set up against the opposite wall. “Over here.”

Applejack rolled her eyes. “What, you want me to move some hay? Out of everything you could think of, that’s the best you got?”

Big Mac shook his head and turned to face his sister, cheeks visibly redder than normal. “Well, uh… Seeing as yah mouth is what got us in this mess, I figured you could use it to, uh… convince me to not tattle-tale on yah.”

Applejack looked over at him, truly perplexed. “Uh… what? You want me to sing you a little ditty or something?” She chuckled and waved him off with a hoof. “I gotta say, I was not expecting that! But, if that’ll do it…”

“No no no.” Big Mac shook his head. “I don’t want you to sing. Trust me, I’ve heard you sing before and, well… let’s just say that once was enough.” Applejack glared at him with a fiery anger in her eyes as he sat down. “No, what I want you to do is use your mouth” - he leaned back and pointed between his legs - “down there.”

Applejack’s head tilted to the side. “What? What do you-”

She looked down.

“...oh…”

There, resting against the inside of her older brother’s thigh, was a big, red, throbbing stallionhood and a matching set of orbs that looked like round, juicy apples between his legs. Each was smooth and devoid of hair, causing his junk reflect some of the light filtering in through the barn’s overhead windows. The snake-like appendage would flex against his thigh every so often, almost as if it was beckoning her forward with a friendly little wave that brought an embarrassed heat to her face.

Applejack looked up at her brother, cheeks flushed and mouth agape in shock. “Wh-what in the hay? Have you lost your apple-picking mind, Mac!?” She stomped a hoof and shook her head. “Nuh-uh. No way, no how. I ain’t givin' you a… a…” She pointed a hoof between his legs. “You know! That just ain’t right!”

Big Mac casually shrugged his shoulders, but he was starting to feel a little antsy on the inside. “Well, if you don’t wanna, you don’t gotta.” He stood, wincing as his rigid cock slapped against his stomach in the process. “I guess Granny is gonna be a mite disappointed to hear about you and your little lie…”

Applejack watched her brother head towards the door, eyes drawn between his legs to watch his low-hanging balls slowly sway side to side. The sight caused the heat in her cheeks to spread, crawling through her veins like warm apple cider to eventually encompass the entirety of her body. Most of it, however, settled in a certain spot between her legs and continued to fester as she watched the orbs hypnotically swing back and forth, a strange hunger building in her mind as she imagined what the stallion-fruits were brewing just for her.

“M-Mac… Hold up a sec.”

Big Mac stopped just a few short hoofsteps away from the door and glanced back at his sister. “Hmm?”

“Ain’t it…” Applejack sighed and rubbed her forehead with a hoof. “Ain’t it wrong for us to be doin’ that? Not just from an age perspective, but from the whole… sibling thing?”

The stallion turned around and shrugged his shoulders. “Maybe, but does it really matter if nopony knows? It’s not like it’s hurtin’ anypony.” He sat down and tapped his chin in thought. “Besides, the whole anti-incest thing is because of the belief that two closely related ponies would produce offspring with birth defects due to their limited gene pool.”

Applejack blushed. “Oh, okay then… I guess ah’ll-”

“So,” Big Mac continued, “seeing as you can’t exactly get pregnant as long as none of my sperm makes it inside your womb and impregnates your egg - which, by the way, seeing as you're not in heat, would be really, really hard - there really shouldn’t be much of a problem. Of course, with any kind of sexual interaction, you always need to remember to-”

“MAC!”

Big Mac jumped in place. “Wh-what!?”

Applejack rolled her eyes. “Celestia above, do you ever stop talking?” She nodded towards the bales of hay. “Ah was tryin’ to say that ah’ll do it. Just… Just don’t go tellin’ nopony about it afterward, you hear?”

Big Mac stood, an ear to ear grin splitting his face in two. She said yes! “Sure thing, Applejack.”

Walking back to his spot in front of the hay, Big Mac sat with his back against the bales and spread his legs out as far as they could go. Another wave of apprehension washed over Applejack as she got another look at her sibling’s genitalia, though this time it was met with a matching wave of burning curiosity. What did it feel like? What did it taste like? Was his larger than average? Was it smaller? Gosh, it sure seemed big, especially whenever it throbbed against his thigh and-

“Hey now!” Chuckling, Big Mac brought a hoof down and teasingly tapped the inside of his thigh, jostling his fat balls and rigid cock around with foal-like glee. “You just gonna stare at it, or are you gonna start usin’ that little mouth of yours?”

Applejack blushed. “D-don’t go rushin’ me, Mac! It ain’t like this is something ah do regularly!”

Big Mac smiled at his little sister. It wasn’t every day a young stallion like himself had the chance to experience the pleasures of a blowjob and, for some reason, the idea that he was going to get one from his very own sibling was making him harder than he could ever remember being in his life. In fact, as Applejack laid down between his legs, thick, gooey strands of pre had already started dribbling down from the tip of his cock, some dropping to the floor while others rolled down his shaft and balls to make his flesh glisten in the light.

Applejack, now on her stomach just a few hoof-lengths away from the stallion’s crotch, rolled her eyes as she looked up and saw the dopey smile on her brother’s face. “Jeez, Mac, you look as happy as a foal down at Sugarcube Corner!” She looked down at his cock and blushed as she noticed it was pointed straight at her face like a large, red arrow. “S-so you want me to… with my mouth?”

“Mhmm...” Reaching between his legs, Big Mac comfortingly patted his sister on the cheek and smiled. “Though, why don’t you start a bit lower? I saw you peeking at mah… apples when I got up to leave...”

Applejack’s cheeks lit up redder than her brother’s. “Oh… O-okay…” She swallowed the sudden buildup of spit in her mouth and looked down at the fat orbs nestled between her brother’s thighs. “Here goes nothing…”

Closing her eyes as she leaned into her brother’s lap, Applejack apprehensively extended her tongue from the safe haven of her mouth and, with a quick, darting motion, tapped it against the stallion’s ballsack. Just that was enough to send shivers up both siblings’ spines, and when Applejack did it a second time Big Mac tilted his head back and moaned.

“H-hey!” Applejack pulled back and pouted at her brother, though the effect was somewhat ruined by the throbbing piece of pony-cock hanging in the air next to her face. “Keep it down! Ah don’t want Granny to hear yah and come investigatin’!”

Big Mac blushed. “S-sorry, but that felt really good…” He licked his lips and smiled, weakly. “Do you think you could… suck on them a bit?”

Applejack’s cheeks turned the same color as the apples on her flank. “S-suck ‘em?” Her tail lifted into the air behind her. “S-sure thing, Mac. Let me just get used to, uh… workin’ with these apples for a bit…”

He nodded. “Okay, sounds- oooooh!”

Shoving a hoof in his mouth to muffle his moan, Big Mac’s entire body tensed up as his sister dragged her tongue across the smooth hills of his balls. The wet warmth was like nothing he had ever experienced before, a kind of lingering pleasure that only amplified as she swiped across his nuts for a second time. A third lick forced his head back against the hay, eyes half-lidded as he stared up at the ceiling in shock.

Down below, Applejack had been slowly gaining confidence each time she lapped at her brother’s balls. The saggy sack was smooth against her tongue, and whenever she pressed her face between the stallion’s legs she could feel their warmth radiating against her face. All in all, she had to admit that it wasn’t half bad; Past a small undercurrent of saltiness, no doubt from their walk to and from Barnyard Bargains, her sibling’s foal-makers really didn’t have much of a taste at all!

What it had in spades, however, was a kind of masculine scent that left her feeling lightheaded enough that she had to pull away and take a breather after only a hoof-full of licks. She continued to stare at her brother’s junk, chest heaving and cheeks flushed as she looked over the haphazard lines of spit she had left on his testicles. The orbs had a strange familiarity to them now, almost as if her first bout of licks had burned away whatever apprehensions she had been feeling at the start and replaced it with a lustful hunger she had never felt before.

Big Mac looked down at his sister, his chest heaving as hard as hers was from pleasure alone. “Why’d you-uuohh my stars!”

Her hunger getting the better of her, Applejack closed her eyes and shoved herself muzzle-first between her brother’s legs. The pillowy cushions of his balls greeted her with a warm, friendly embrace, smothering her lips with soft, scrotal flesh and filling her lungs with that same, masculine scent from before. She moaned against the spheres as his cock flopped against her forehead, the pre-slickened shaft matting down her fur with her sibling’s seed as it throbbed against her face.

“A-Applejack!” Big Mac moaned as the mare started lashing out at his sack with her tongue, jostling the sensitive orbs around between his legs like her life depended on it. “Wh-what are you do-oooooohhh!”

Opening her mouth as wide as it could go, Applejack scooped one of her brother’s massive ‘apples’ into her mouth and closed her lips around the far side of the meaty orb, encasing it within the warm, wet prison of her maw. She moaned as she felt it’s hefty weight settle against her tongue, the vibrations resonating against the seed-silo as it tried to churn out more of her sibling’s seed. Her tongue swirled around it like a furious snake, coating each and every inch of its smooth surface in saliva until she couldn’t taste anything but flesh.

Opening her eyes, the young mare glanced up at her brother and smiled around the thick orb bloating out her cheeks like a chipmunk's. Big Mac, mouth hanging open and hooves resting at his side, had pressed his body against the bales of hay behind him and had his head tilted towards the ceiling. Applejack’s eyes fell half-lidded as she watched him twitch and squirm with each drag of her tongue, her brother’s muscles rippling underneath his fur as she serviced him. The thought that she, his very own sister, was bringing him such pleasure caused her hunger to multiply several times over, so much so that she wasn’t sure how she could ever sate it.

But she could certainly try.

Big Mac gasped as Applejack released his spit-soaked ball back out into the air with an audible pop, his angrily throbbing cock flexing against his stomach as it begged him for some relief. He would have loved to do nothing more than give it some himself, but before he could even think about lifting a hoof his lust-crazed sister had already taken his other nut between her hungry little lips.

“A-Applejack, could-” He bit his bottom lip to stop another moan from ringing out. “Could you m-move on? I’m g-getting close!”

Applejack, either not hearing him as she hummed around his testicle or just not caring about what he said, continued to nurse on his balls like a foal would their mother. He tried to get her attention again, but the constant waves of pleasure numbing his mind turned each attempt at speech into a gasp or a groan. So, without that as an option, the quivering stallion used what strength he had left to lift a hoof and place it against his sister’s cheek.

“Hmm?” Applejack opened her eyes and looked up at her brother. Her eyes met his, and from just the amount of need she saw in his eyes she realized he wanted her - no, needed her! - to give him some proper relief.

Pulling back from her brother’s lap, Applejack let her brother’s evenly-glistening sack plop back out onto the barn floor. She didn’t stay for long, though, not with the incessant hunger egging her on from the back of her mind, but, this time, she aimed herself towards the pre-slickened tip of her brother’s stallionhood.

A shocked gasp broke into a weak croak as Big Mac felt his sister’s plush lips wrap around the sensitive head of his cock. He stared down at her for a moment, eyes wide in amazement as he realized his sister was about to give him a blowjob. Her eyes locked with his for a moment, and he swore he could see a mischievous glint in her gaze before, closing her eyes once more, she dragged her tongue across the broad tip of his flare.

“Oh my sweet Celestia!” Big Mac bit his bottom lip and hissed a moan through his clenched teeth. “Oh my stars, that feels amazing!”

Applejack hummed in approval around the stallionhood in her mouth. With her brother being so large both in body size and in cock size, she could only fit the head and about half-a-hoof of his shaft past her lips. That happened to be more than enough, though, because as she started circling her tongue around his pulsing prick the fat orbs beneath it repaid her earlier ministrations with a healthy dollop of pre. The salty-sweet fluid was like nothing she had ever tasted, and as she lapped at the head of his cock like a dog would a bowl of water she swore she could sense the faintest taste of apples in his pre.

Big Mac shivered as his sister continued sucking his cock, his legs weakly kicking out on either side of the hungry mare’s body. The pleasure he had felt as she had been sucking his balls was incredible in itself, but it was nothing compared to what he felt now. It felt like the top of his shaft had been encased in a warm, wet cavern that squeezed around it like a vice. In fact, it was so pleasurable that he could already feel the pangs of an oncoming orgasm, one that felt hundreds of times larger than anything he had ever had during his ‘me’ time back in the sanctuary of his room.

“Applejack…” The young stallion began to take heaving breaths, mind focusing on anything but the mare between his legs to prolong the euphoria coursing through his veins for as long as possible. “I’m close…”

Applejack replied to his comment with another hearty moan around his cock, and when the feisty mare started using her hooves to rub at his balls - no doubt trying to milk the heavy apples of their juice - he brought his down to the back of her head. “Celestia above, AJ… How are you so good at this?”

Applejack smiled and pulled her head off of his cock. “Th-thanks… Whew, I gotta say, this here is hard-hmph!”

Big Mac let out a long, drawn-out sigh of pleasure as he shoved his sister’s head back onto his cock, sinking an extra inch further past her lips in the process. “Sorry, Applejack… Suck now, talk later…”

Applejack would have rolled her eyes and grumbled at her brother had it not been for the fact that the wide head of his cock had just slipped into her throat. Her eyes widened as he continued pushing on the back of her head, causing his meaty shaft to slowly slide down into her gullet like a fat snake looking for a new home. Hundreds of emotions passed through her all at once; fear, longing, disgust, and even a little bit of love. But, above all else, she felt a burning need ignite between her legs, one that only grew hotter as she imagined that the bulge of her sibling’s dick could be plainly seen against the light-orange fur of her throat.

Of course, it was only a matter of time before the fact that her brother’s cock was acting as an air-proof plug started to sink in. Luckily, as Big Mac slipped the last couple inches of his shaft past her lips, he reversed direction and began pulling her away from his cock.

With a wet pop the log of pony-flesh popped from her mouth, letting her cough into a hoof to clear her airways of the snail's trail of pre it had left in its wake. “Jeez, Mac, I thought for a moment there that-”

She never got to finish her sentence. Had she been paying attention to her brother’s clenched-up face as he withdrew she might have been able to prepare herself for the coming cum-pocalypse, but as it was she was completely caught off guard as he let out a loud, bellowing moan and the first blast of seed rocketed out of the tip of his cock to splatter across her cheek.

“H-hey! Watch what-”

Again her words fell into silence as the second salvo of seed, this one no less voluminous than the first, fired out of his stallionhood-turned-gun and struck her right between the eyes. Luckily, none of the sticky substance was able to land directly in either of her eyes, though the gasp that resulted from the unexpected white-wash gave the third blast a clear shot right onto the tip of her tongue.

Which, as the stallion-cream swirled around her tongue, was enough to shut her up for good.

Laying on her stomach with her eyes closed between her brother’s legs, Applejack settled for holding her mouth open as wide as it could go as splattering after splattering of seed arced through the air and landed on her face. Her cheeks, her forehead, her mane, her mouth, nothing was safe from the onslaught of stallion-cream, the apples she had so deliberately taken care of earlier repaying her for her efforts ten-fold. In fact, by the time Big Mac sighed and slumped against the bales of hay, most - if not all - of her face had been plastered in her brother’s genetic goo.

“Mmm… Dang, I needed that…” Big Mac chuckled, the euphoric afterglow of his orgasm slowly settling in. “I must say, that wasn’t half-bad, AJ. Might have to get you to lie about things some more!” He looked down at his sister, eyes widening as he saw the scene of devastation before him. “Oh my… Did I do that?” He sheepishly rubbed the back of his head. “Sorry, AJ, guess I was a little pent up…”

Applejack chuckled and used both of her hooves to wipe away the cum from her eyes. “Pff, yeah, I guess so!” She looked down at her chest and sighed as she saw various strands of the sticky stuff haphazardly strewn across her chest. “Jeez, I’m gonna have to go wash up ‘fore dinner… No tellin’ what Granny would think seein’ me like this!”

“Seein’ you like what?”

Both siblings’ eyes widened in terror and, in perfect synchronization, they turned towards the barn door. There, sticking her head in through the top half of the door, was the one pony they really, really did not want to see…

“Uh…” Applejack smiled and weakly waved a hoof, strands of her brother’s cum dripping from her face. “Hi, Granny!”

Applebloom looked at her sister with wide, awe-filled eyes. “Ah can’t believe you told all those lies!” She looked over at the far barn-wall. “And ah REALLY can’t believe you and Mac… did stuff right over there!”

Applejack smiled. “It’s not a story ah’m proud of, but it taught me a lifelong lesson about being honest.” She looked over at her brother and smirked. “And it taught Big Mac over here to be a little quieter during our private get-togethers. Turns out, the barn’s walls ain’t that thick and, well, when he let out that big, bellowing moan, Granny heard it all the way from the kitchen!” She turned her gaze back to Applebloom and nodded her head, wisely. “Ah hoped you learned something, too.”

Applebloom perked up. “Ah sure did! I learned that nopony starts out perfect and sometimes you gotta make a few mistakes to figure out who you are.”

Big Mac nodded. “Eeyup.”

Standing, Applebloom glanced towards the door and smirked. “Plus, I learned that I really need to stop having sex in the barn! To the clubhouse it is, then!”

With that, Applebloom marched past her stunned siblings and, thankfully, sleeping Granny and threw open the barn doors, disappearing past them without another word.

Applejack looked at her brother out of the corner of her eyes. “Did she…?”

Big Mac nodded, weakly. “Eeyup…”

“Huh…” Applejack spared a glance over at Granny and, seeing the mare snoozing away in her rocking chair, turned back towards her brother with a grin. “Say, wanna go another round back in my room?”

Big Mac smirked. “Ah thought you’d never ask…”

Author's Notes:

After a day delay, here's the promised Apple-cest for last week's episode! Had a blast writing this chapter (having only one-on-one pairing ideas for the weekly poll was definitely a good idea on my part), though I find it strange that it somehow wound up being shorter than last weeks... Ah well, hoped you guys/gals enjoyed it! Thanks to everyone who submitted ideas for this chapter, was able to add 2/3 of them (ran out of time for a good anal scene )
