“Augh, what happened to me?” Applejack muttered, her eyes opening to reveal that she was in what looked like the barn.

After her vision cleared the woman discovered that she was indeed in the barn, and was currently laying on her back, arms and legs spread wide. A slight breeze alerted her to the fact that she was more or less naked, as the only thing she wore was a thin pair of panties. The second thing that she realized was just how incredibly how she was, followed closely by how much she reeked of sex.

“Wait, where is Flutter…” Applejack’s question died before it could be uttered, the sudden shock of seeing her own warped body causing her mind to temporarily shut down.

Her tits were incredibly huge, massive beyond scale, and completely inhuman. Each one was the size of one of those extra large bean bag chairs that she had seen at Twilight’s place one time. Not only were they mammoth in size but they were also so heavy that they felt like lead weights had been strapped to her chest.

“N-no. This can't be happening.” Murmured the woman, who nervously reached an arm around each of her tits only for the slight movement to nearly make her orgasm.

The ensuing sloshing sound that emanated from each of her immense breasts was akin to getting into or out of a full tub. Not only were they heavy and loud, but they also sent a surge of hormones through her body, making it a struggle to even think. The fog which Applejack had managed to drive off before returned with a vengeance, and she had to fight to not break down right then and there.

Glancing nervously at her surroundings, Applejack found that Granny Smith’s old wheelchair had been placed within arms reach. Grasping at it, Applejack pulled it closer before engaging the lock on the front wheels and beginning to pull herself into a stand. Only to find that she simply couldn't get up completely and was forced to awkwardly shift into the chair from a half crouching position.

Once seated the woman breathed hard, releasing her hold on her huge tits and letting them settle around her legs.

What truly got to the woman was the fact that the brief movement had been more than enough to make her muscles burn. The running of the leaves hadn't even taken that much out of her, nor did a full day of hard physical labor.

“This can’t be real. I can’t be bound to this wheelchair. This is a dream, it has to be…”

She wanted to scream, to cry out in rage but she found herself unable to as tears built at the edge of her vision. A helpless sadness filled her soul, and for a moment she merely sat there sobbing as a dull pressure began to well inside of her. Her breasts churned, and for a moment Applejack thought she was about to start producing milk.

Sniffing, Applejack wiped away her tears, and placed her hands on the wheels of the chair only for the sound of the barn door opening to make her stop. “Wh-who’s there?” She asked nervously.

“It's just me.” Muttered a deep, familiar male voice.

Applejack breathed a little sigh of relief and relaxed slightly. “Oh thank goodness. It's just you Big Mac. I worried it might have been Apple Bloom or Granny.”

“Eenope.” Big Mac stated, the male trotting up behind his sister, remaining just out of sight.

“You uh, wouldn't happen to know what happened last night do ya?” Applejack inquired. “I can't really remember much for some reason.”

“You two went a little crazy,” Big Macintosh began. “I had to take Fluttershy home after she passed out on the barn floor.”

“I suppose that's good.” Applejack murmured, her gaze drawn inevitably down to her mammoth tits and the fear the sight of them instilled in her.

The pain and embarrassment of it all was bad, but that paled in comparison to a different worry that had taken root in her brain. It had begun the very second Applejack had even imagined Fluttershy, the mere thought making her body begin to grow hot. Not only that but she also felt herself beginning to grow thirsty, her body yearning for more delicious milk.

Milk that was so addictive that Applejack felt as though her very soul was urging her to drink more of the stuff. That wasn't the only addictive thing about the shy woman however, as Applejack also couldn't help but think back to what bits and pieces she did remember. She thought of the passion they had shared, the incredible, mind bending, awkward sex they had right there on the ground. Was it really sex or were they just humping each other with their tits?

Big Macintosh watched his sister closely as she stared off into space, her chest heaving slowly as she breathed. His need burned hot within him, making the male stare hungrily at the woman’s massive breasts. They were the biggest he had ever seen by a country mile, and the mere sight of them made his thoughts turn dark.

“I need some water.” Applejack muttered half to herself half to Big Macintosh.

“Sure thing.” Big Macintosh replied slowly.

His hand reached for a nearby bottle and after a moment of hesitation he reached out and grabbed it. Opening it up, he handed the opaque bottle to his sister, watching as the woman took it and was about to take a swig only to stop. Her nose prickled, and she looked down, eyes widening with both horror and slowly dawning realization.

“It was you,” She murmured. “You did this.”

“You did this to yerself.” Big Macintosh rumbled.

Applejack shook her head and tossed the bottle aside, causing the milk to spill all over the ground. “You put the milk in the fridge. You poured out all the water, and kept pushing me to drink more of that damned stuff!” Applejack shouted.

Big Macintosh paused and slowly exhaled.

“...I just wanted to see how big you’d get.”

Applejack’s knuckles went white and her fingers dug into the arm rests of the wheelchair. “I’m your sister. How can you say that?”

“It started out easy enough. I was just curious to see what would happen.” He paused. “Yer beautiful AJ. Sexiest damn women alive”

The breath suddenly left Applejack’s lungs and she felt as though someone had kicked her in the stomach. “And what if it's permanent?” She whispered.

The male stepped forward, revealing his massive erection which stuck straight out from its cloth prison. For a moment Applejack couldn't think of anything, her brain too busy struggling to come to grips with her brother suddenly revealing himself in such an intimate manner. Though the male still wore pants his bulge was so huge that Applejack swore she could see every vein on Big Macintosh’s cock.

“And what if I never stop growing?” Applejack murmured absently.

Big Macintosh merely grunted, his cock visibly growing right in front of her eyes, twitching until it had become an inch longer.

She gulped slowly. “And what if… what if I explode?”

The man’s cock twitched and erupted with seed which stained the front of his pants with a growing wet spot. Applejack’s jaw hung open and she watched as her own brother orgasmed mere inches from her face. Her breathing grew quick, and her chest tightened, fear mixing with anger until her entire body shook with barely contained rage.

“You’re… you're a monster. .” Applejack clenched her teeth.

“Now look, I know I got a bit carried away but I’m sure we can talk this out.” Big Macintosh muttered, the male taking a step back.

“There is nothing to talk about.” Applejack declared, turning her wheelchair in order to look him in the eye as she began to yell. “Your going to get your incesteous, perverted ass of my goddamn farm this fucking instant and thats all there is to it.”

Big Macintosh frowned and held up his hands. “Now hold on a second there. I know I got a little out of line there but that ain't no reason to try and kick me out of the house.”

Applejack growled, and jabbed a finger at him. “I’m the element of fucking honesty. I know yer lying, you wanted this to happen. You wanted me to get so big I couldn't move, that I’d be at your mercy like some sort of a… a....”

Her tits gurgled as thought to fill in the blank.

Big Macintosh frowned. “Now that ain't true.”

“Like hell it isn't,” Applejack stated angrily. “Look at me Big Macintosh! What the hell can I do by myself? ? I can't even stand up for crying out loud!”

Big Macintosh opened his mouth to offer some retort only to frown and close it once more.

Applejack slowly shook her head. “How could you do this to me? You're my kin and you ruined me. I…”

The woman paused as a loud rumble emanated from her breasts a second before the pressure returned. It began as a mere tingling sensation, then grew to a pus and finally morphing into feeling like someone had stuck a hose into each of her tits. Instantly her breasts began to feel tight, and the hormones which had been beaten down by her anger came back with a vengeance.

“No… oh celestia no...”

Applejack remembered Fluttershy describing the sensation she got right before walking over to the farm each night and this was exactly that. Only even Fluttershy had never described the pressure being this all-consuming before, as Applejack felt as though she may legitimately explode in mere moments. Her nipples grew wet and within seconds of the pressure returning Applejack could feel twin streams of milk shoot from them.

“Oh god I’m lactating just like Fluttershy. Sweet Celestia! Oh-h-h Celestia!.” Applejack winced, her fingers digging into the hand rests. “Get the machine Mac, hurry!”

Big Macintosh ran to the otherside of the room and threw open the door to the stall before unplugging the machine and going to grab the empty glass containers. His hands stopped midway however, his gaze settling on the large and very full container already resting there. A war erupted within him, his dark desires battling against the need to be a good big brother and do what needed to be done.

Slowly, the male leaned to the left and peered out of the stall and towards Applejack’s wheelchair bound form. Just in time to watch as two powerful jets of milk erupted from her tits from mere pressure alone. His jaw hung open and as he stared Applejack writhed and moaned, grabbing her bean bags as more white liquid shot from her nipples.

“Milk me. Oh sweet Celestia, someone milk me!” She cried.

Instantly everything became clear to Big Mac. He knew what he had to do. He leaned back around and grabbed the full tank of milk before hooking it up to the machine. Reaching down, he flipped the reverse switch and disengaged the overflow valve and hauling the entire thing back over to where Applejack sat. The woman was still writhing in barely contained discomfort and overwhelming arousal, her body twitching as more milk poured from her breasts.

Without question Applejack shifted her chest and gripped the handrests tightly, waiting for Big Macintosh to do the rest. She didn't have to wait long though, as the male all but jammed the cups over her nipples and flicked on the machine. To her horror milk was not pumped out of her, but rather into her, filling her breasts at an incredible rate. The pressure doubled in an instant.

“Oh mmmmmyyyyyy gawdddddStop.” Applejack cried, before falling slack as she moaned loudly, a bolt of pleasure coursing up her spine and making her entire body tremble.

Her eyes rolled briefly into the back of her head and she stared down at her chest with a mixture of horror and revulsion. Where before she had grown an inch or two a minute now she was growing twice that every few seconds. Her trembling hands reached out in an attempt to tear free the suction cups but it was just out of reach and Big Macintosh was faster.

Holding her hands down, the male forced his sister to sit and watch as more and more milk was pumped inside of her. The pressure was insane and though her resistance continued, it was quickly becoming eclipsed by just how insanely good she was starting to feel. Letting loose a cry of rage and confusion, Applejack heaved her arms upward, yet Big Macintosh was too strong and the effort turned out to be a wasted one.

“PPPPlease I’m begging you, don't-t-t do this. It's not too late to turn back!” Applejack cried, her eyes rolling into the back of her head as her mind was awash in a strange mix of pleasure and pain.

Big Macintosh said nothing, his expression remaining firm and unmoving as he merely stood there and watched his sister continue to grow.

Throwing herself violently against the male’s grip, Applejack fought desperately to free herself, yet nothing seemed to work. He was too strong, and every single time she tried to slip out of his grasp he adjusted in order to ensure she accomplished nothing. Only when she felt the handlebars of the wheelchair snap did her resistance falter, giving way to confusion.

What she saw made her nearly break down completely, as her breasts now touched the ground, and were so heavy that Applejack awkwardly fell from the ruined chair. Now half kneeling on the ground, the woman was forced to realize that she would likely never be able to walk again. she was now completely dependent on others.

Her arms fell flat, and Big Macintosh released his hold on her, knowing that there was nothing she could do at this point. For several long seconds the machine continued to chug away, pushing more milk into her breasts. Yet Applejack couldn't even seem to bring herself to care, the weight of her own helplessness stopping her from feeling anything.

“You always were the fattest apple around, what with that giant ass of yours.” Big Macintosh began, a cruel smile spreading across his face. “Now you have the fattest tits in all of equestria.”

“N-no. This can't. There has to be a way to…” Applejack whispered.

Big Macintosh ignored her and unzipped his pants while walking around the woman, his gaze never leaving her still steadily growing tits. Shucking off his pants, the male quickly discarded his underwear, allowing his cock to spring free of its cloth prison. Gripping the throbbing length in one hand, the man bent down, and roughly grabbed hold of his sister’s ass, shoving her down.

“Wha-whats going on?” Applejack demanded, the girl nearly pulling her hair out as she began to succumb to the pleasure.

Big Macintosh merely grunted, and shoved his hips forward, ramming his cock into Applejack’s sopping hole. He couldn't get very deep due to the odd angle, but he didn't care, as he had finally managed to enter her. The ensuing gasp, and shudder that came from Applejack made Big Macintosh grin, and he grabbed a firm hold of her ass.

Before her mind even had time to catch up to what was happening to her body, Big Macintosh squeezed his sister’s ass and rammed forward. The tight, cloying depths of the girl’s pussy parted before his strength, his length ploughing through the meagre resistance her body put up. Again and again he drove himself deeper, plunging more of his cock into his sister’s tight hole until finally he was balls deep inside of her.

The feeling was beyond comparison, and Big Macintosh nearly came right then and there, but he managed to resist. He wanted to hear her moan and really mean it before he stuffed her womb full of his incesteous seed. With a grunt of exertion, the male thrust forward at a rapid pace, his gaze shifting from between Applejack’s rippling tits and enormous jiggling ass.

His grip tightened, his thrusts sped up, and his balls slapped audibly against his sister’s body. Biting back his own moan, Big Macintosh watched as Applejack lay there, her arms still flailing but unable to reach him. She seemed completely lost in the sensations assaulting her, the panic and pleasure turning her into a desperate, moaning mess.

With a snort, Big Macintosh spread her ass cheeks wide and forced her butt higher, allowing his cock to grind extra hard against her g spot. The ensuing cry of pleasure was like music to his ears, and the male smirked as his orgasm came roaring back. His fingers dug into Applejack’s ass and he thrusted forward one final time, burying every inch of his rock hard cock inside of her.

The second he was as deep as he could possibly get, the male came hard and fast. Each pump of seed was delivered directly into the deepest reaches of the woman’s body, ensuring that none could escape.

“Do you feel that Applejack? Do you feel my cum pouring inside of you?” He whispered, his cock twitching needfully as it did just that.

Applejack shuddered. “Sounds about right, ”Big Macintosh declared with a smirk, his cock remaining hard even after his orgasm had finally stopped.

The male didn't question his good fortune, and continued to pound the woman’s abused pussy without pause. Each thrust made a soft squelching noise, yet Big Macintosh didn't care one bit. He was fucking the hottest peice of ass he had ever laid eyes on and nothing would stop him from enjoying himself.

“You know your probably pregnant by now.” Big Macintosh remarked.

“N-no. It didn't take, it can't have.” Applejack pleaded, her body trembling.

“Maybe it hasn't, but that's why I’m not going to stop at just one. I’m going to cum inside of you over and over until your stuffed to the brim with my seed.” Big Macintosh growled.

“Oh goddess above, please make it stop.” Applejack cried.

“It's never going to stop, you’re going to grow into my own personal milk factory.” Big Macintosh whispered.

Applejack opened her mouth to speak, but her words turned into a cry of pleasure, and her entire body shook. Her pussy clamped down around Big Macintosh’s massive, throbbing erection, squeezing down on his length. Her cart-size breasts quaked with tremendous energy, having continued to grow larger and more sensitive with each passing second.

“Give in.” Big Macintosh whispered, leaning forward. “Become my slave and do nothing but grow and make milk for me.”

“No…” Applejack’s retort died on her lips.

“Do it or else I wont milk you ever again.” Big Macintosh threatened. “And we know what will happen then.”

Applejack’s legs twitched, and she moaned as the feeling of pressure grew to truly baffling levels, her breasts now drum tight as if she may very well explode at any moment. Not only that but she could feel her brother’s second orgasm shoot inside of her, making her womb fill past the point of being full. She could feel the skin around her stomach grow taut as the sheer amount of seed warped her body.

“That's not possible.” She whispered, only for a hand to tell her it was true.

“Go on Applejack, say you’ll become my slave. This is your last chance.” Big Macintosh warned.

For a moment the woman was tempted to resist, to fight back and tell him off and then she felt the last drop of her brother’s load settle inside of her. Like a switch getting flipped, Applejack felt something change inside of her, part of her mind finally succumbing to the pressure and the pleasure. Between having her breasts forcibly grown to inhuman proportions, her brother’s massive erection spreading her wide, and the cum she had forced inside of her, it was too much.

“I can't take it anymore. Sweet Celestia I need to be milked so bad!” She cried, her breasts growing to the point that she could see them near the barn wall.

“Say it!” Big Macintosh yelled.

“I’m your cow, your milk factory, your anything pleasure just for the love of god make it stop before I pop!” Applejack cried.

Big Macintosh pulled out of his sister with a wet slick, and raced over to the machine, which he hastily turned off. Walking back, over to the woman, Big Macintosh marveled at just how truly monstrous her breasts had become. Each one was nearly bigger than he was, and contained so much milk that each errant twitch made them slosh noisily.

Kneeling down next to her, Big Macintosh stared into the woman’s wild, glazed eyes. “Say it, say that your my cow, my slave to do with as I want.”

“I’m your cow, your slave. You can do whatever you want to me.” Applejack replied after a pause .

“Yell me you don't give a shit about Apple bloom anymore.” Big Macintosh urged. “Say that you’ll let me fuck her whenever I want.”

Applejack’s wild, manic expression faltered, and for a moment a frown crossed her face. “I can't!!.”

Big Macintosh frowned, extended a hand and slapped her breast as hard as he could. “Say it!” He shouted.

The woman’s eyes rolled into the back of her head, and her body shook as she came right in front of him. Yet even after she opened her mouth no words came out, only a garbled, unintellegable moan. Big Macintosh frowned, and extended his arm once more, ready to deliver another hard slap.

“Yes, master, whatever you want! You can fuck Apple bloom, make me grow, do whatever you want to me just please, give me more!”

Big Macintosh smirked, and gave her tit another firm smack, causing the woman to cry out in pleasure, orgasming from just having her tits smacked around. “Welcome to your new life.” Whispered the man.

Applejack grinned drunkenly, her eyes rolling around in her head as she slowly came down from another enormous high. Only for something to short circuit inside of her already over stimulated mind, causing the woman to slump forward. Her entire body went limp, propped up only by her enormous breasts that continued to spray milk.

Standing, Big Macintosh retreived his undergarments and pants, slowly donning his clothing as the sense of triumph washed over him. By the time he had unbuttoned his shirt, that feeling of victory had given way to a slow, insidious dread. As he looked around the male realized the true depth of what he had done as both the barn and his sister were ruined.

Not only was she family, but she was an element of harmony, one of the most important people in Equestria. And here she was, laying sprawled out overtop of her ludicrously huge, and permanently engorged tits. There was no way Applejack would ever do anymore world saving, unless whatever bad guy came to her.

Worse yet, her friends would definitely come to check on her given enough time, and not only her normal friends, but the other elements. His breathing grew quick, and Big Macintosh looked around the room, searching for something to help him. His gaze landed on the empty, discarded bottles which littered the floor only to find that not a single one of them contained more than a drop of milk.

The larger containers were similarly empty, meaning there wasn't a drop left of the corrupting milk.

Or was there?

Big Macintosh walked forward, and glanced down past Applejack’s engorged nipples and towards the tinted pool of milk below. An action that was slightly hard to do as his gaze didn't want to leave his sisters nipples which were about the size of his head at this point. Shaking off the growing temptation to rut the woman again, Big Macintosh dipped a finger into the milk and sniffed it.

His frown vanished, replaced by a wide, confident smile which grew with each passing second. Everything was clear now, from his destiny, to the course of action he must now take, it all made sense. He had to control them, or they would control him, and he had the means to do exactly that.

Smiling, Big Macintosh ran a hand through his sister’s hair. “Do you want some other cows to play with? Hmm, Applerack? What do you think of that?”

Lost in catatonic pleasure, Applejack merely drooled in response.
“Good, because I can already think of five other cows who would fit in here just fine.” Big Macintosh exclaimed with a smirk.
