Author's note: As you may know, I do fapfics for request. I've had an awful lot of requests for Apple family incest fics. These were all conceived as separate stories, although there's some continuity between them, and they all share a theme. So I thought I'd post them as chapters just for convenience. This first one is a very, very early story.

Big McIntosh was hammering away. Running a farm was tough business. Sure, farms could bring in a lot of revenue, but the profit margins were razor thin. They had to cut as many corners as they could. That’s why he was out here in the workshop behind the barn, where they had a small forge. Most families would just pay the few extra bits to have their horseshoes repaired at the proper blacksmith’s in town. Not his family though, nope. Why pay money when for a few hours of hard labor you could solve the problem yourself? Or at least have Big Mac do the labor and solve it for you. He was the only one with the strength to handle the bellows and the hammer. Finally done hammering the horseshoe into shape, he plunged it back into the bucket of water one last time. He was done here. Time to move onto the next chore. He paused for a moment, looked out the shop’s wide door, and wiped the sweat from his brow.

His little sister was trotting up the path. She was soaking wet. She had a bucket by the handle in her mouth. She also had a large smile on her face. It wasn’t a sinister grin, Big Mac noted. She was much to devious to look devious. It was just a big happy beautiful smile, like she didn’t have a care in the world. As she got close, she didn’t say “hi.” She just laid down the bucket in front of him, and pulled at the brim of her hat a bit. Drops of water flew from the hat, turning a golden color in the afternoon light.

Big Mac looked down into the bucket. It was half full with lumpy white butter.

“Oh, not again,” he said.

“Oh, c’mon. Quit being such a baby,” AJ said. “It’s not like you don’t want it.”

“What I want is something else. You know what I want.”

“Oh now don’t you start your fussing. I won’t have this argument again. You know how long it took me to churn that butter?”

“The same time it takes you to churn butter every day?” he asked.

“Every day? C’mon, big brother. You know I’m not that hard up. Quit fooling around.”

Big Mac didn’t respond except by sighing. His sister could be so demanding. There was no point in resisting it. His sister trotted around, being careful not to spill the bucket, and kissed him on the cheek. She always kissed him on the cheek. Never on the lips. She was such a strange filly. It just made him angrier. AJ could tell. So she kissed him on the cheek again. And again. She kept kissing him, moving up towards his ear. Finally, Big Mac broke into a sheepish grin.

His sister returned the grin. “There, that’s not so bad. It’s all down hill from here, OK?”

“Okay,” was all Big Mac could say.

AJ tickled his nose with her tail; Big Mac inhaled deeply as she did so, then she ducked under his torso. She didn’t have to duck very far. His frame was so much larger than hers, she almost looked like a nursing foal. She stuck her face up to his balls. Now as it happens, ponies are always naked, their bits hanging out for everyone to see. Of course, in polite pony society nobody is supposed to look. And nobody ever does, especially AJ. Except when she and Big Mac were alone, of course. She loved his balls. They were bigger than any apples, and more fun to play with. She loved how soft and pink his sack was; it was free of the coarse red hair on the rest of his body. She nuzzled up into it. First up the middle; his balls spilling over either side of her snout. Then she stuck out her tongue and jostled each one. She took first one, then the other halfway into her mouth, rolling her tongue around.

Big Mac moaned. It was sort of low rumble. His whole ribcage vibrated. AJ loved that sound, especially from underneath him. She took a step or two back, and put her lips up to the loose skin of his sheath. Her tongue darted forward. He was salty. She reached further with her tongue and just touched the tip of his dick. She tasted the sweet taste of pre-ejaculate. His dick stirred. In one fluid motion, it slipped out of its sheath and into her waiting mouth.

She had to take another step back. She couldn’t take it all, not that she didn’t try. Big Mac was proportional to his size. She could take his glans, at least. And she could take it halfway up the shaft. She took it out of her mouth and corn-cobbed it for a bit, working her way up and down the shaft. Soon he was flying at full mast.

“That about does it,” she said, proud of the sight.

“If you say so,” her brother said.

“Hush.” AJ went over to the bucket and scooped up a glob of butter in her hoof. She went back to her brother’s cock and started smearing it up and down the length of it. She couldn’t help but work some of it on with her mouth.

“I’m gonna get chubby if I keep doing this,” she said.

Big Mac just snorted in response. Soon she had his dick covered. Well, most of it. There were still a few rough patches. And other patches where clumps of butter still stuck, unsmeared.

“Good enough,” she said, getting excited.

“If you said so,” Big Mac said again.

“Hush.” AJ looked around the workshop and found something she could use. She pulled an old ratty horseblanket from off a shelf and draped it over the anvil. She stepped over it with her front legs, and got up on the padded anvil with her hind knees. Her rump was sticking way up in the air, just the perfect level for her brother and his erection.

“I’m all yours,” she said.

“Not all of you.”

“Now don’t start.”

Big Mac came forward, but hesitated. “You’re all cleaned out, right?”

“Of course I am. You know the drill. I just spent the last half hour in the river facin’ downstream. Why do you think I’m all wet?”

“And you’re gonna return the favor?”

“Have I ever not returned the favor? Quit horsing around. I’m all ready.”

Big Mac came forward again. He stuck out his tongue and centered it straight on his sister’s anus. He had a big dick, and she had a tight ass; sticking it in was never easy. They had both gotten it down to a science. She giggled a bit at first, and then guffawed in the way that she does sometimes. It tickled. He tasted... nothing, which was fortunate. Except perhaps for some river water, which was fine. He tried to get his tongue in a bit, but it didn’t make it far. It always surprised him how this always happened, despite his girth. He wanted more lube, so he licked downwards, stroking his sisters cunt with his whole tongue. Again, river water and just a mild hint of her usual flavor. But the smell of her pussy made his nostrils flare. He was already fully erect, but her pheromones sent him into overdrive. He could feel the blood pressure rising in his dick, stretching it as far as it would go.

“Now you be careful down there, Big McIntosh,” AJ said. “Don’t you go popping my cherry.” Big Mac returned to her ass. His tongue slid in easily now that it was slippery with his sister’s juices. “You know how proud I am of my cherry. Princess Celestia says that good ponies abstain from sex before marriage. She doesn’t say nothing about no butt-fucking, or blowjobs, or rimjobs, or 69ing, or hornjobs, or eating out other fillies. But she’s clear on sex. So I’m waiting. Yessiree, big brother. I’m saving my cooter for some nice colt one day when I get married. I’m a good and proper pony. I...”

“AJ!” said Big Mac, pulling out for a moment.

“What?”

“Stop talking,” he ordered.

She was going to apologize, but she just shut her trap. Big Mac went back to work. Big Mac had heard all that before. A million times before. It was a bit of a sore spot for him. He just didn’t seem to understand her situation. She almost felt guilty for enjoying this rimjob. Oh well, the main course was coming up.

Big Mac soon had his sister ready. Her butthole was nice and relaxed, and all lubed up. He stepped over her. He didn’t even need to mount her properly, he was that much bigger. AJ swung her tail out of the way. Big Mac waited for his cock to stop swinging back and forth. Once it had, he shoved it into his target.

“Careful,” AJ reminded him. Big Mac said nothing. He was always careful. His middle name was careful. He worked himself back and forth, only the tip of his dick actually going in. AJ moaned and cooed beneath him. He couldn’t see her face, but he was sure she was biting her lip and had her eyes shut tight. His sister was one tough cookie. It took him several minutes of working it back and forth by a smidge before it was in good and proper. It wasn’t all the way in, but it was as far in as it was probably going to get. Big Mac didn’t want to force it. This was enough for the both of them, so Big Mac set to work, thrusting away.

AJ was screaming and hollering. She always loved this part. She was shouting like it was some kind of rodeo. Big macs balls were slapping up against her pussy, stimulating her clit. They always had a big wet patch on them after they got through with this. He could never exactly tell when his sister was cumming. She just always shouted like this. Could have been one big orgasm for all he knew. He never asked, and she never told.

Truth be told, he was getting tired of this little ritual of theirs. They’d been at it since they were foals. He wanted her pussy, and he wanted it bad. He understood why she wouldn’t give it to her. That didn’t mean he didn’t want it any less. Maybe he wanted it even more because of that. It was very unfair, but what could he do?

Big Mac shoved his sister so that her knees slid off the anvil and she was on all four hooves. He was standing on his hind legs, his front hooves around her waist. He was careful not to put too much weight no her. He knew she couldn’t take it.

“Walk,” he said.

“What are you doing?” she asked, dumbfounded.

“Just walk,” he said. “Into the barn.” He nipped a bit at her neck and she started walking. She looked out of the workshop in case anybody would see. He shoved again, and she tried to hurry up to get into the barn. Anybody looking would have seen her with her brother’s dick up her ass. She made it to the barn without anybody seeing, or without Big Mac falling out. They were beside a big pile of loose hay.

“What are you thinking?” she asked. She was confused, yet amused at his strange behavior. This was some new game of his. It turned her on. And then she screamed. Big Mac picked her up by the torso and fell back into the hay. AJ shrieked with laughter. Here Big Mac was, lying on his back in a big pile of hay, with his dick straight up AJ’s butt. She was squatting over him, facing away, and naturally started working herself up and down.

She liked this, she quickly realized. She was in control now. It was a new experience to her. Getting it up the butt could be rough, and now she could work it just the way she wanted it. She was holding onto her brother’s upright legs for balance when she looked down. She could see her own pussy, and now that she wasn’t on her front hooves, she could play with herself. With her brother’s dick up her butt, and her own hoof rubbing her clit, she entered a new world of pleasure. She looked down again and realized that if she used her imagination a bit, it looked a bit like she had sprang a pair of her own balls. Big Mac’s balls stuck out from underneath her exactly as if they were her own. So she started playing with those too.

Big Mac must have liked it. He was grunting and snorting below her. She could go deeper too, in this position, almost all the way to the base. It was as far in as it had ever gotten. Big Mac was heaving underneath her. Finally he threw her off into the hay and stood up. She got onto her four hooves, expecting him to take her from behind again. Instead, he threw her back into the hay, this time on her back.

He had a wild look in his eyes. He spread her hind legs apart in front of him. His massive erection almost looked sinister. She had never seen him like this before in all their years.

“Now, don’t you do it,” she screamed, suddenly frightened. “No! Don’t! Don’t stick it in my...”

Big Mac stuck it in. He stuck it back in her ass. AJ breathed a sigh of relief. Her brother was fucking her butt in the missionary position, that was all. It was new to her, though. She realized that he was getting it all the way in, and it didn’t even hurt. She just felt all full up. His eyes were rolling into the back of his head. He was enjoying this. She was surprised to find that she was too. There wasn’t much reason for her to be doing so. Her pussy was just sort of pointing straight up in the air. Nothing was touching it. His balls were hitting the small of her back instead of slamming into her clit the way she liked it. Still, she liked this. It was like he was fucking her pussy from behind. She could feel it pushing her upwards. In fact, as she looked, she could actually see her belly heaving up where Big Mac was pushing on it from the inside. She wondered what it would be like if he came inside her. He hadn’t done that since she was little. Usually she just took the butt-fucking, then went behind him, “returned the favor,” slapped his boner up against his belly a few times, and he’d come. That was good enough for him. He liked that. She was liking this. A few more minutes and she might actually cum. It didn’t look like she would make it, though. Big Mac was about to blow. He had that look on his face again.

Suddenly, Big Mac leaned forward and kissed her full on the lips. He wasn’t supposed to. That was just somthing brothers and sisters didn’t do. He forced is tongue all the way in. AJ didn’t stop him. She almost came because of it. Then he pulled out of her. He swung his cock upwards, and then down on top of her with a big wet smack. It stretched near from her rib cage down down over her belly button, between her erect nipples and over her crotch. Big Mac shoved her thighs together around his shaft.

“What do you think you’re doing this time?” she demanded to know.

He pulled out once from between her thighs, and then shoved back one more time in, slamming against her as hard as he could. She was looking right into it when he came. He gave her every ounce he had. She turned her head up and away, but it just splashed everywhere on her chin. He pulled away, leaving a wide streaming trail of semen from top of her forehead to her crotch. He chuckled, then fell into the hay beside her, exhausted.

She tried to rub it off with the hay, but she only got hay all over herself, sticking to the cum.

“What did you go and do that for, silly?”

“I like to cum on you, sis,” was all he said.

“You know we can’t do that anymore. Use Applebloom if it’s that important to you.” That was a joke. They hadn’t gotten their sister involved in any of the fun yet, although they had both thought about it. “ We haven’t done that since before I blossomed into marehood. Look... see? You’ve got it all over my cooter. If you got me pregnant, I’ll never get married. I’ll have to stay here forever, a spinster.”

“Relax, it ain’t all bad.”

“Oh, and why in tarnation not?”

“Then I’d get your cooter all for myself,” he chuckled.

“Shoot, sugarcube. That’s almost sweet.” She got up from the hay, still covered in cum and straw. “Look at me, I’ll have to go down to the river to bathe again.” She started off, dripping cum as she went.

“Hang on, I’m coming with you,” Big Mac said, getting up to follow. His flaccid member still hung from his sheath, also still dripping.

“Why?” she asked.

“Gotta get cleaned up. You still need to return the favor.”

“Are you serious? You just came!”

“You promised.”

“Fine, fine. I can’t stay mad at you, big brother. Is after supper good for you?”

“Eyup,” he said.
