The Origins of an Apple's Blossem

Many years past, Applejack had awoken one early spring day feeling...strange. It was not long after Winter Wrapup - a slight chill still in the air and a few patches of snow still melting here and there in the warm spring sun. Applejack decided to get up and then sluggishly walked outside after getting a drink and heading to the outhouse, her unusually tense muscles making her short walk that much harder. Figuring some fresh air would help her feel better as it usually had, she'd headed outside - needing to go to the outhouse and make her morning visit there anyhow.

Long story short, being outside didn't help... at all.

As soon as the warm sun touched Applejack's coat, she felt a sudden burst of heat ripple across her skin, trail down her back, and end up at her haunches. As she noticed that, she also felt her lower belly starting to burn inside - feeling as though somepony had lit something on fire inside her and left it slowly smoldering in her lower belly. She'd had had a number of Hay Fevers and other such illnesses in her still-short life of eleven years, but nothing quite like this!

Applejack went into the outhouse, still feeling the now-constant burn in her lower-abdomen as she went pee. Oddly, she found she was unable to empty her bladder as she usually could, seemingly retaining some and unable to get it out no matter how hard she pushed.

That was weird.

As Applejack once again walked into the dreaded sun, she felt between her legs starting to burn hotter in response to the warm sun, making her softly moan in discomfort. Applejack was starting to really freak out now as she felt the burn in her belly increase along with the burning in her crotch, desperately looking for a source of relief.

Then she spotted it - a patch of cold, wonderful snow right next to her. Applejack flopped her burning crotch into the nearby patch of leftover snow, sighing at the relief she got as her vulva touched that soothing coldness. Her orange coat was softly shimmering in the spring sun from her sweating, but she noted it wasn't even that hot out. Matter of fact, it was slightly nippy!

Applejack felt her head get light suddenly as she smelled a strong, unmistakably male scent coming from behind her as her muzzle detected the scent of a stallion's pheromones nearby. The snow she was sitting in was no longer able contain the strange heat emanating from her loins since this morning as the burning intensified now from that odor, between her legs growing hotter as her juices started to increase and drip onto the already-wet ground beneath her.

Applejack groaned softly in discomfort as her body's need grew, a need for what she didn't know, but she knew she instinctively that she needed something and that she needed that something badly. As she felt a muzzle sniff and press against her seated rear, Applejack shot up and moved her tail up and to the side as her small flower winked against the air on reflex, letting out another soft moan and spreading her back legs as she peed a little on the ground - unintentionally yet instinctively inviting the male behind her to breed her in the most primitive and obvious way possible.

Applejack felt as the stallion was climbing on top of her—identifying him as her brother when she saw his large red-haired hooves wrapped tightly around her small hips—and got a good grip around her hips before she even knew what was going on. When she felt him starting to thrust against her and something hard and warm prodding against her inner stifles and flank, all she could bring herself to do was spread legs further – instinctively giving the stallion a better chance of hitting his mark.

Applejack gasped as she felt the soft-warm thing press against her burning crotch, only to move up higher a moment later – then she felt it press against her tailhole.

This wasn't right. This didn't feel like how this was supposed to happen, and Applejack's instincts were telling her to make this stop.

As she felt Mac press against her virgin plothole, Applejack let loose a surprised cry of pain as the thing started to push inside, a bolt of pain shooting through her rear as her butt was suddenly stretched open. After she'd cried out, she felt Mac tense up -as she'd apparently startled him, then felt the hooves around her hips loosen and the weight on her croup disappear as a hoof slid along instead.

Mac apparently had climbed off her, leaving her feeling more disappointing then she knew why.

~

The next minutes were very awkward as she asked Mac what had happened and clumsily apologized, starting to explain what was happening to her body - and trying to explain why he'd been trying to 'put his pee-pee up her butt'.

With her instincts still screaming at her, Applejack listened as Mac explained the basics about the birds and the bees to her, mainly focusing on her  'heat cycle' and how she would react to stallions during this time - sloppily telling her why she'd reacted the way she did when he'd approached her and nudged on her croup, as well as why he'd mounted her and started doing as he had.

As Mac explained more about the facts of life to her, Applejack felt the faint ember in her ignite -  starting to feel the soft heat in her belly and between her legs increasing again in intensity as her brother stumbled through the description of breeding he'd apparently learned from Granny Smith - their vagueness and euphemisms only working to fuel her heat more.

Applejack looked at Mac's still-hard breeding rod the entire time as he explained what mounting was and what happened after, unable to pull her eyes away from it as the foreign thoughts of having it inside her overtook her thoughts.

She needed it...needed him inside her.

Now.

"...and then th' bee fertilizes the honeypot with his stinger, an if th' plot is fertile—." Mac finished trying to explain, only managing to mostly confuse Applejack with his rambling - with her only able to pick up the absolute basics of what Big Mac was saying.

As she was still trying to piece together what he was trying to tell her, Big Mac suddenly said something that more-then-mildly surprised her.

"Maybe Ah could jus' show y' how it works. Whaddya think, li'l' sis?"

~

Her brother's offer instantly stoked Applejack's curiosity, making her feel another burst of heat and prickling from between her legs at the thought. Applejack considered for a moment what he was suggesting - that he would climb on top of her and start to 'breed' her by putting his 'stinger' in her 'honeypot', he'd move around a bunch and make her 'fertile plot' feel real good, then shoot his 'honey' into her and make her 'flower' stop burning when he 'fertilized' it.

Applejack then nodded to herself as she turned to Mac and asked him her question. "S' all Ah gotta do is stand here and be 'breeded' by you, it'll feel real good, an' then this here itchin' and burnin'll go away fer good?"

Mac nodded and opened his mouth again, but Applejack wanted to hear none of it. Applejack put a hoof over Big Mac's mouth as he again tried to talk, silencing him as she then turned and shook her rear at him – her clit winking to him again on reflex as she flagged her tail up, revealing her swollen and very moist fillyhood to him. She needed this burning to stop  and if all she had to do is be 'breeded' by her brother to end it, she'd gladly do it!

"Well, then get on t' breedin' me already!"

~

Applejack felt as something nudged against her swollen slit, gasping at the sudden sensation of being rubbed down there.

"Big bro what're ya...aaaaaaaaah." Applejack started to ask, but instead of finishing she sighed in approval as Mac's muzzle started softly nudging against her needing flesh - that simple touch sending bursts of pleasure flowing through her and making her lean back into his muzzle, making her start needing more of that wonderful sensation.

~

Applejack tensed up as Mac moved away after she'd leaned back onto his muzzle, hoping she hadn't screwed up somehow – but relaxed again when he returned seconds later and started to lick her slit harder. As she felt a bolt of pleasure race up her spine, Applejack rewarded her brother with a shudder and a hard moan as his tongue drove into her now, penetrating her fillyhood and making her groan in satisfaction.

When Applejack felt a massive burst of pleasure seconds later, she wanted more. She leaned back against Mac's muzzle, feeling it spread her passage slightly more as well as rub on that wonderful spot he'd hit before again.

"M-mmm-more there..." Applejack barely managed to stammer out, quickly feeling another wave of pleasure flow through her as Mac's tongue once again assaulted her pleasure button, licking hard and making her tremble underneath him as bolt after of bolt of pleasure traced her spine -overstimulating the mare as she gasped for breath.

With pleasure surging through her young body, Applejack couldn't feel anything anymore except the tingling pleasure throughout her whole body as her brother's inexperienced tongue then penetrated her lips and start flopping around inside her passage.

"D-Don't stop bro..." Applejack moaned out as she dug at the ground in front of her hard with her front hoof, feeling as she parted the soft soil and left large gashes in the ground as she struggled to cope with her first eating-out.

Applejack's heat-addled body couldn't care less the skill of the young stallion - with Mac merely flopping his tongue around inside her and not even trying to find the sensitive spots every mare had. All her body cared about was that her needing marehood finally had something moving inside of it, and it eagerly clenched down on that object hard to prevent it from getting away.

As Mac amateurishly licked inside his sister for a moment more, Applejack suddenly moaned deeply as she felt her pleasure suddenly spike massively, her whole body tensing up as she felt something big washing over her all of a sudden – crying out as she finally felt something inside her figuratively snap.

All Applejack saw was white as she felt the most intense pleasure she ever had before, feeling Mac's tongue still flailing inside her before suddenly stopping as she felt her powerful muscles squeezed down hard on it, the sensation of it being pressed firmly between her muscles making her whine in her pleasure as another wracking wave jolted through her, making her tremble at the intensity of her first-ever orgasm.

~

When she'd come off her orgasm and was still panting for air, Applejack turned her head and faced back as she felt her brother's large hoof press onto her rear, followed by him wrapping both around her hips and his lower belly rubbing against her croup. The stimulation made her reflexively arch her hips up into him and spread her legs wider as her body reacted to the young stallion now on top of her, preparing her for what was next.

When she could speak, Applejack found she could only speak in a very throaty voice she'd never heard from herself before. "So now yer gonna breed me, huh?" she asked, getting a squirm of a brother on her back as a response. She sighed happily as she felt his belly rub against her croup, making her even more horny now that her stallion had her mounted and had her pinned beneath him - making her his.

Not responding past squirming on her back, Applejack felt as Mac instead started grinding against her croup rapidly as he started to thrust against her again, this time aiming lower and in the right direction! When she felt him press against the entrance to her lower hole, she felt him clutch her hips tightly as he thrust in suddenly – hard.

Applejack saw white as she felt a very satisfying fullness inside her now, sating her breeding instincts instantly upon entry. Applejack moaned in blazing pleasure as she felt Mac press into her more, only stopping after he'd hilted in her, leaving her smaller body utterly stuffed with his comparatively huge colthood.

Mac apparently was giving her a moment to breathe as he stayed still inside her, planted to the hilt. Applejack took advantage of this by taking in the sensations as she felt his 'stinger' buried deep inside her – feeling every throb it made and every vein on its surface, the slightly-expanded tip pressing against something that led to the itch deep inside her belly. As she felt her muscles softly rippling over his rod, she sighed in contentment – her fillyhood had finally gotten what it so desired and she was and not letting it go.

After both had caught their breath sufficiently and Applejack had nodded her consent, Mac started his pace at a slow hump. After a few gentle thrusts, Applejack instead felt as he started thrusting deep and fast into her, making her pleasure suddenly spike up another notch as he started properly breeding his mare on instinct.

~

After a number of the hard thrusts – with each one pressing against something very deep inside her foal-tunnel – Applejack started whinnying again as she cried out.

"Mac, Ahm...!"

As she uttered that, Applejack's inexperienced body started clenching down hard on Mac's rod as she came again, pleasure silencing her as her young stallion pounded her further even while she shuddered and groaned through the extreme pulses of pleasure now surging through her.

Even as she rode out her second orgasm, her body trembling under her brother as she was rutted hard for her first time, Mac didn't stop his thrusts into Applejack – instead pounding into her even harder to get through her tightly-clenching muscles!

He apparently needed this as much as she did now!

~

A passionate scream escaped Mac's throat as Applejack started whinnying again, the young mare feeling pulses from his "stinger" inside her, along with feeling deep inside herself being spread wider as it seemingly grew inside her! She could feel her deepest depths spreading further as Mac's 'stinger' flared, soon followed by a few more hard throbs as a wet warmth started spreading very deep inside of her – clearly his 'honey'.

The feeling of that warmth and of being filled and stretched so tightly extended her orgasm, making Applejack start to scream anew as Mac started to shoot his load into her passage, sending his first waves of young stallion cream into her as he started planting his seed into her very fertile 'plot'. Mac started thrusting hard again when he started cumming, gripping his sister's barrel tighter as his instincts demanded he hold her still and force himself as far into her fertile body as possible. His penis was apparently a perfect fit for Applejack's breeding canal as, with a few more deep thrusts, his flared head kissed then pressed against her cervix – his twitch-twitch-twitching shaft now gushing directly into her virgin womb and letting nothing escape as his flared head sealed against it with each thrust.

Applejack weakly moaned out one last time as she felt Mac bite her crest, adding that extra bit of stimulation and making her fall silent and limp as she suddenly lost consciousness - blacking out from the extreme pleasure and over-stimulation as she came once more.

Applejack awoke what Macintosh had told her was a few hours later, a sweet floral scent surrounding her. As she opened her eyes, she noticed a number of apple blossoms surrounding her - odd, since there were no apple trees over her. As she looked up and saw Mac sitting under a nearby tree, she got up on still-wobbly hooves and walked over to him, intent on asking him what happened.

"Mac...what...happened t' me?" Applejack asked in a still-sleep-ridden voice.

"Y' passed out after Ah... 'fertilized' yer 'honeypot'." Mac told her, and she saw a slight blush coming to his face as she heard those words proudly spoken from him.

"Wow..." Applejack said as she suddenly remembered a few hours past, flooding her with memories of the extreme pleasure she'd been subjected to, then it all fading to black. "...you were...great!"

"You too sis. Ah don't think Ah've ever felt so great in mah whole dang life!" Mac exclaimed, then wrapped a hoof around her neck, pulling Applejack into a hug.

Then it hit Mac. "Yer gonna get pregnant!" he nearly screamed, making Applejack jump at the sudden noise.

"What're ya hollerin' about? What's 'pregnant'?" Applejack asked, totally confused.

Mac considered how to tell her, not even totally understanding himself - "Y'see, when a mare and a stallion get t'gether and do what you 'n' Ah did when a mare has a 'fertile plot fer seeds' like you do, the mare will generally get 'pregnant' with a foal!"

Applejack still didn't really understand what 'pregnant' meant, but she did know what a foal was. "Y'mean Ahm gonna have... a foal?"

Mac nodded, a look of extreme nervousness crossing his face as he braced for her reaction.

"Ah love you Mac!" Applejack cried, wrapping her hooves around his neck and tackling the unsuspecting young-stallion to the ground in a hug.

"Yer... not mad?" Mac said after Applejack had stopped choking him with her hug.

"MAD!? Shoot naw, Ahm excited!" Applejack said, still not knowing the gravity of her situation, nor what being pregnant at such a young age entailed. "Ahm happy Ahm gonna to have a foal, Mac! Yer the best big brother ever!"

Mac smiled at his sister's compliment, and then remembered something else. "Applejack?"

"Yes big bro?"

"Y' can't tell anypony we did this today."

"Why not? We're gonna have a foal-!

"Because Granny Smith told me that family's never supposed to 'breed' together - somethin' about 'genes' and 'bein' too close'. Ah don't know what jeans gotta do with anythin', but it can't be good that we're family and just did that. Ah need you to promise me y' won't tell Granny Smith or anypony else you 'n' Ah did this today."

Applejack only paused to consider for a second. "Ah promise big bro, an' that's the honest truth!"
