Applejack x Big Macintosh

Every year in Equestria, all stallions go through heat – a time when their rational judgment is overridden by the need to rut any mare they come into contact with. Thankfully there’s a herbal remedy that allows them to ease the symptoms and live somewhat normally during this time. But what happens when there’s a shortage of the herb in Ponyville?

WARNING: Contains incest, rape, and impregnation.

“Oh no no no no no!” Applejack said worriedly, trotting in place nervously. “This can’t be! Yer all out?!”

“I’m afraid so Applejack.” Shop Keep said regretfully. “I take it the heat has taken your brother?”

“Ya got that right!” Applejack said loudly. “Have y’all ever tried to contain that stallion? It’s impossible! He’s got the strength of ten ponies….probably twenty! Please, you’ve just got to find me some more!”

“I’m sorry but the next shipment is tomorrow.” Shop Keep said. “Surely he can contain himself until then right?”

“He just seemed a little flustered when ah left.” She said. “But who knows how long it’ll be before he’s trying to bash the door down to get at all the mares? What time does the shipment actually come?”

“Eight.” Shop Keep said. “I’ll make sure to save you a bottle.”

“Thanks a lot Shop Keep.” Applejack said. “Ah’ve gotta get back home quick. Big Mac’s probably already getting delirious.”

With that Applejack made her way back to the farm. She thought about asking Zecora if she had any of the herb, but this particular herb only grew on the outskirts of Equestria in the coldest of climates. Not something Zecora would have lying around here. Besides, she had to get back to her brother…

As she made her way into the farmhouse, the sound of steady banging made her freeze.

“Gosh darnit, what’s he up to now?” Applejack said to herself.

She made her way upstairs slowly, making sure to avoid one of Winona’s toys that was lying on the third stair. As she approached Big Mac’s room the sound intensified. She peered into his bedroom to find him banging his head against the wall.

“Hey Big Mac.” Applejack said, walking over to him.

He didn’t respond and kept hitting his head against the wall.

“Big Mac!” Applejack said loudly.

“Huh?” He asked, in a daze.

“Here.” Applejack said, turning him around with her hoof. “We’ve gotta get you back to bed.”

Big Mac complied without resistance and let her lead him back to his bed. He slid in slowly and she tucked him in like a little colt.

“There…” She said softly. “Y’all just rest up, go to sleep, and ah’ll have the herbs for ya in the mornin’.”

Big Mac giggled in an uncharacteristically giddy way.

“What?” Applejack asked, somewhat indignantly. Something about the way he was laughing made her somewhat self-conscious.

“Heeee….” Big Mac said, smiling dumbly. “Yer really pretty Applejack……”

His statement took her aback for a moment before she recomposed herself and laughed.

“Yeah, yeah.” Applejack said, patting him on the head. “That’s nice Big Mac. And yer in heat. So why don’t ya’ll just shut yer eyes and try to go to sleep?”

“Kay…” He said, sighing happily. “Mah pretty little sister….”

Applejack rolled her eyes and left his room, shutting the door behind her. It was kind of funny how he always said stuff like that every year he went into heat. And she enjoyed the ridiculousness of the situation. But it also worried her. Normally by the time he got to this stage, a full flare up of his heat was soon to hit. Still, eight in the morning was less than twelve hours away. Surely he could make it that long, especially if he slept for most of it. He might have a wet dream or two, but then this would be all behind them.

Unfortunately this was rather bad timing for his heat. Applebloom and Granny Smith were off in Canterlot for a doctor’s appointment. She had Big Mac had wanted to come, but they were too far behind on the applebucking to even consider it. She sighed. They’d still be behind. Even after Big Mac got the herbs, the heat was very taxing on him. He would have to spend most of the first few days in bed.

Applejack knew that keeping her brother contained in that room was the most important thing. If he went out into the real world controlled by his heat like this, there was no telling what he’d do. Stallions lost nearly all control of themselves during their heat. So she resolved herself to sleep on the floor outside his door tonight. It would be uncomfortable, but she couldn’t take any chances. She went to her bedroom and grabbed her blanket before putting it onto the floor and laying down. Yup. It certainly was uncomfortable. But it was worth it. Just twelve more hours…. Twelve more hours….


Applejack awoke with a start as a loud bang resonated throughout the house. Her head shot up as she looked around trying to find the source of the sound. Seeing her surroundings, she remembered exactly what was going on and why she was sleeping in the hallway. She shot to her hooves and put her mouth close to the door.

“Big Mac?” She whispered. “Is that you?”

Silence followed. Just when she was about to shrug it off and try to go back to sleep, another loud bang sounded. This one definitely came from his room. It was followed by several more bangs in rapid succession. BANG………BANG……BANG…BANG…BANG!BANG!BANG!BANG!

Applejack threw the door open and ran inside. She found Big Mac jumping up and down on his bed, his hooves hitting it with each jump and causing a big bang.

“Stop it Big Mac!” Applejack yelled. “Yer gonna break yer bed! How old are you?!”

Big Mac jumped off his bed and landed on the floor in front of it.

“Ah need her!” He exclaimed. “Ah need her now!”

“Who?” Applejack asked.

“Berry Blossom!” He bellowed. “Ah need her right here right now and right here and now and here and now!”

He started walking towards his open bedroom door. Applejack stood in front of him and stopped him with her hoof.

“Woah nelly!” She said worriedly. “And what exactly do you intend to do when you find her?”

“Ah…..ah don’t know….” Big Mac answered truthfully. “Ah just really need to be there with her!”

“Big Mac, yer in heat.” Applejack explained. “And yer not goin’ anywhere ‘till its over.”

Big Mac looked at her in surprise.

“Ah’m not in heat.” He said.

“Yes you are!” Applejack said, her patience wearing thin. “Yer just gonna have to trust me here Big Mac.”

“Ah’m not in heat.” He insisted.

“Fine.” Applejack said. “Yer not in heat. But it’s the middle of the night. Y’all can go see her tomorrow.”

“But ah wanna see her tonight!” Big Mac said insistently.

He pushed forward and tried walking towards the door again but Applejack pressed back, stopping him in his tracks.

“To bed.” She said simply.

“But…” He said.

“To bed Big Mac!” She yelled. “Now! Ah won’t tell ya again!”

Big Mac stopped trying to get to the doorway but he didn’t make any move to head back to bed. He stared at Applejack with longing eyes. Noticing his gaze, she put a hoof up to cut him off.

“Don’t ya’ll be lookin’ at me like that.” She said. “Ah’m yer sister.”

Big Mac shook his head quickly, trying to clear his mind.

“Sorry Applejack.” He said. “This heat is a really bad one. Ah’m having a real hard time controlling my thoughts. Ah’ve really gotta get back to bed.”

“It’ll be alright Big Mac.” Applejack said reassuringly. “Just sleep ‘till eight thirty and ah’ll have the herbs by then. But ya gotta try to get a hold of yerself, ya hear?”

“Eeeup.” He said quietly, walking back towards his bed. “Ah’ll try Applejack.”

“Ah’ll be right outside the door here.” Applejack said. “Just let me know if ya need anything.

Applejack walked out of his room and shut his door. She walked over to her room to find a clock. Midnight. Only eight more hours untill this was over. Satisfied, she went back out into the hall and laid down on her makeshift bed, trying to go back to sleep.



Big Mac’s voice sounded very weak. Hearing his voice through the door, she immediately awoke and stood up.

“What is it Big Mac?” She asked.

“Ah……ah need yer help…..” He said softly.

“What do you need help with?” She asked cautiously.

“Ah……AJ this heat is really bad.” He said. “Ah need you…..”

“There’s nothing ah can do Big Mac.” Applejack said sympathetically. “Not ‘till eight thirty tomorrow.”

“Yes there is…” Big Mac said. “Applejack……..yer a mare…..”

Applejack was taken aback by this statement. She had been with him through many of his heats, but he’d never said anything like this. She could tell he was really bad off. So bad he was even thinking of her that way.

“Big Mac, we can’t.” She said. “Ah’m yer sister, remember?”

“Ah know….” He said softly. “Ah’m sorry Applejack. But ah can’t help it. Ah want you……”

There was a long silence between them. Applejack didn’t know what to say. Finally Big Mac broke the silence.

“Can’t ya do somethin’?” He asked, pain in his voice. “Please Applejack. We won’t take it too far. Ah promise…..”

“Ah………..ah can’t Big Mac…….” She said softly.

She felt so bad for him. He was obviously in pain and having difficulties.

“Can’t ya just use yer hooves to……….” Big Mac asked quietly, not able to bring himself to say it. “Ah………ah’m so hard right now. It hurts…….”

Applejack’s eyes widened at hearing this. Her brother had a hard-on from thinking about her. The thought made her wet. Applejack had been with stallions in the past. Sure, they wanted her. But not like this.

She quickly came back to her senses. This was her brother she was talking about! If that wasn’t bad enough, he was in heat. What was her excuse? If she gave into him like that when he was in heat, she would be taking advantage of him. She couldn’t do that.

“Ah’m really sorry Big Mac.” She said. “But yer gonna have to take care of that yerself.”

Applejack heard groans of discomfort from the other side of the door and hoovesteps heading away from the door and towards his bed. She heard him get into bed and then silence. She let out a sigh, realizing he had went back to bed. She laid back down and went back to sleep, eager for morning to come.


Big Mac couldn’t get to sleep. He had tried hoofing off many times throughout the night, but nothing worked. He’d went weeks without pleasuring himself. Months even. But this was so much worse than that. He needed a mare. The only mare available was his sister Applejack. If she had been any other mare, he probably could have restrained himself. But he’d been attracted to his sister for far too long. Those feelings were strong before, but the intensity of his desires now were overwhelming. He couldn’t even think straight. He needed her. He needed her badly. He needed her now.

He got up slowly, walking over to the door as silently as he could. As he reached it and prepared to open it, he stopped himself, shaking his head violently and trying to regain some form of control.

What was he doing? He loved his sister. He really did. He couldn’t do this to her. He looked at the clock. Three in the morning. If he could just make it five more hours, he’d be free of this incessant heat. He looked at the door. Applejack was there, lying less than a foot away on the other side of that door. She was his sister. His beautiful sister. He gritted his teeth, trying to resist his urges and turn around. But he couldn’t stop staring at the door. His hoof trembled as he reached out and touched the handle.

If….if she just sucked him off, he was sure he could control himself. She had refused to help him. Not that he could blame her for that. But he had no choice. He needed her. And if she refused to help him…..

He couldn’t hold back anymore. He flung the door open quickly. Applejack raised her head in surprise, looking at him in shock. Seeing her face he froze. He couldn’t do this to her.

“Big Mac?” She asked in surprise, moving to stand up.

He knew that if she stood up, his chance would be lost. His mind snapped and he was suddenly overcome with lust. He stepped over her quickly. Surprised, she tried to move her head to get out from under him. But he grabbed her head and held her in place, putting his member right in her face.

“Big Mac, what are you……?!” She asked frantically, struggling to pull away from him.

He pushed his body forward a bit, touching her face with his member. Applejack realized what he was doing and panic overcame her.

“Big Mac, no!” She exclaimed.

But he was too far gone. He bucked his hips, making his member hit her in the face several times. Afraid he would accidentally hurt her if she didn’t comply, she quickly opened her mouth and let him slip inside.

Just being around her made his lust increase tenfold. He did everything he could to get her to take his member. But she kept resisting. Finally he felt as she willingly opened her mouth and enveloped his member, her hot maw sucking him inside. He moaned loudly as he felt her nose hit the base of his shaft, his member now completely enveloped by her warm, wet mouth. He quickly withdrew then pushed back in, muzzlefucking his sister with quick but gentle strokes.

“Ahhhhh, yes………” He said, sighing deeply.

Applejack couldn’t believe what was happening. Big Mac had lost control of himself and was raping her! She tried to resist, but he was just too strong. She didn’t stand a chance. At first she was appalled at the situation. She felt used and betrayed. But as he continued, she started to get aroused. She scolded herself. She wasn’t supposed to get turned on by this! This was her brother she was sucking off. And worse than that, she was being raped! But after a few minutes she stopped struggling against him. Feeling this, he loosened his grip on her head. Eventually she was sucking him off on her own accord. She bobbed her head up and down his shaft, eagerly awaiting his finish.

Big Mac had stopped holding her head completely by now. With all four of his hooves on the ground, he was able to fully enjoy the treatment. His member pulsed as she continued, ready to erupt at any moment. Eventually it did. He moaned loudly as he came, his member pumping glob after glob down his sister’s throat. Applejack knew it was coming, but wasn’t prepared for how much he actually came. She swallowed frantically, not wanting to choke. But she couldn’t keep up with it and it was soon coming out the sides of her mouth. She pulled back, grateful that he had let go of her head so she could. She coughed violently, spitting out his cum onto the hallway floor. She looked to the side. Big Mac’s member was still dripping, little spurts of cum leaving his body every few seconds.

Her lungs burned. She took deep breaths, not able to speak quite yet. Her face felt like it was on fire as she blushed furiously, realizing what they’d just done. But there was heat coming from another region of her body too. Her mind was filled with lust too and she realized how wet she was.

Big Mac had loved the blowjob he’d just gotten from his sister. But it wasn’t enough. He looked at her in shame, but that shame quickly vanished as he looked at her firm round flanks. She was still trying to recover, gasping for air with each breath. He decided to take advantage of the situation and stepped behind her quickly, licking her entrance carefully.

Applejack had just barely recovered and wasn’t quite prepared for more sensations. But suddenly without warning, Big Mac stepped behind her and started eating her out. Her mind felt fuzzy as she stood there, letting him taste her nectar. She shook her head, coming back to her senses.

“Big Mac, stop!” She said.

She spoke quietly, almost in a whisper. As if she spoke too loudly they’d be caught. She didn’t think she’d ever been so aroused. Big Mac was good at pleasing a mare, she could tell that much. And that was a part of it for sure. But a large part of it had to do with the fact that they weren’t supposed to be doing it. Applejack felt like a little filly again, going against her granny’s wishes. She unconsciously pushed her flank back towards him, wanting him to go deeper.

Big Mac complied readily, pleased she wasn’t resisting him. He buried his muzzle in her snatch, eating her out expertly. He’d been with plenty of mares before and knew what they liked. And Applejack was no exception.

Applejack moaned loudly as she came, her mind exploding with pleasure as she experienced the most intense orgasm of her life. She shook violently, her front hooves giving out. She was still shaking as she laid with her head against the floor and her flank in the air, her strength greatly drained from her intense orgasm. She laid like this for almost a full minute, enjoying the afterglow of her orgasm. Suddenly a pair of hooves landed on each side of her head and she felt a feeling of dread overcome her as she realized what was happening. Seconds later she felt her brother’s body against her back as he laid over her, his member poking her backside as he stepped over her, bringing his face next to hers.

He thrust his hips gently, his member sliding against her belly as it swung underneath her. She could feel the tip of his member slide along her belly, a bit of pre-cum coating her fur as it slid along.

“Ah’m gonna fuck you Applejack…..” He said, whispering into her ear.

Applejack shivered as he said that, the room suddenly ice cold compared to the warmth of her brother’s body against her.

“Y…….ya can’t……” She said quietly in response. “Ah’m not protected. Besides…..ah’m yer sister, remember?”

Big Mac bit her ear gently, sending waves of pleasure through her body. Without saying another word, he pulled back a little. She could feel his member slide along her belly again, this time going the opposite direction. It slid along her belly until it reached her flank, drawing up right to her marehood. She knew she should fight it. She knew she should stop him. But she couldn’t. She didn’t have the strength to resist. Receiving no resistance from her, he positioned himself, his member resting right at her folds, the tip parting her slowly.

“Please Big Mac….” Applejack pleaded quietly. “No……”

Unable to hold back any longer, Big Mac pushed forward slowly, sinking inch after inch inside of her. He pushed slowly but deliberately, sheathing himself inside of her in a single stroke. They moaned in unison as their hips met, his member now completely inside of her. He kissed her cheek affectionately as he withdrew, the walls of her pussy squeezing him, trying to keep him inside of her. When he was about halfway out, he pushed back in slowly, her muscles tensing up as he bottomed out inside of her.

“Ohhhh….Big Mac……” Applejack said quietly, completely overwhelmed with pleasure as her brother started rutting her.

He started out slowly, savoring each and every second he spent inside his sister. He kissed and nibbled at her neck as he rutted her slowly, putting as much effort as possible into making the experience last. Applejack’s head was still swarming with pleasure, but she found the strength to speak.

“Ya…..ya have to stop……” She said quietly. “We can’t be doing this. Yer gonna get me pregnant!”

“No ah won’t….” Big Mac said just as quietly, biting her ear gently and pulling her to her hooves.

Applejack didn’t respond. She couldn’t. In the back of her mind she knew she should resist. That she should buck him off of her before it was too late. But as the pleasure coursed through her body, nothing else seemed to matter. She gave into him completely, standing there and letting him rut her as his member plunged in and out of her unprotected marehood. All sense of rational thought had left Applejack by then. As he sped up his pace, her entire world centered around his member deep inside of her. She clenched him desperately as she realized another orgasm was fast approaching.

Big Mac was in heaven. Absolute heaven. The warmth and wetness of his sister’s body was incredible. He couldn’t help but groan as her tight passageway massaged his member as he entered her, bringing him pleasure beyond anything he’d ever experienced. He remembered she mentioned something about getting pregnant. But he didn’t care. The only thing he could focus on was rutting Applejack. He sped up his pace, intent on enjoying his sister’s body to its fullest extent. He rutted her for all she was worth, desperate for release. Suddenly he felt her clench down on his member and she started shaking violently.

Applejack’s orgasm hit her with such intensity she almost collapsed. Her mind exploded with pleasure as he continued rutting her, the only thing in her mind being the cock deep inside of her. Her lower region was on fire, intensifying as he continued thrusting in and out of her.

Feeling his sister go over the edge set him off also. He pushed himself inside of her as far as he could go and held himself there. The entrance to her cervix cupped the tip of his member. It twitched a few times before erupting inside of her.

A loud groan was torn from his lips as he came inside of her, his member firing milky jets of seed directly into her womb. He looked down at her body as he impregnated his sister, his member pumping copious amounts of seed into her with each spurt. Pump……pump……….pump……. Each pump filled her up, flooding her womb with his seed.

Applejack was at the tail end of her orgasm when she felt him push into her and hold himself there. She was suddenly filled with panic as she realized what he was about to do. Then, before she could even react, he came. The first shot fired directly into her womb. She was about to wail out in despair, but the pleasure hit her hard. She had never felt something so deep inside her before. He stimulated places nopony had ever stimulated before, sending waves of intense pleasure through her body.

“Ahhhhhhhh…….ahhhhhhhhhhhhhhhh!” She cried out in pleasure as she realized she was being impregnated. Her womb quickly filled up and overflowed, sending his pearly white seed squirting back out of her. It ran down her legs quickly and also pushed Big Mac out of her a bit. He thrust forward defiantly as he emptied himself inside of her. Eventually his member began to die down, a little spurt leaving his cock every few seconds or so. They were both breathing heavily, the sun just beginning to come up just over the horizon.

Applejack felt like she had just ran a marathon. She knew she was pregnant by now, but somehow she didn’t care. Big Mac withdrew from her slowly, a stream of cum leaking out of her now loose pussy. Neither of them spoke. Applejack was the first one to start walking towards his bed. He followed wordlessly. Applejack climbed into his bed and turned, her back towards him. He was suddenly overwhelmed with guilt at what he had done. But there was another feeling he was feeling as well. He got into bed next to her so her back was against his stomach. Taking the blanket in his hooves, he draped it over both of them before reaching down and kissing her on the cheek.

“Ah love ya Applejack…..” He said softly.

There was no response for a long time and he was filled with guilt again. Then she spoke.

“Ah love ya too Big Mac…..” She replied just as softly. “Let’s just go to sleep. We’ll figure this out in the morning.”

Big Mac was still feeling a little guilty and he was still worried about what they were going to do, but feeling the comforting presence of his sister was reassuring. He snuggled up to her and closed his eyes, content with not worrying about anything until the morning.
