The Big Inbreed

“Alright Macintosh, I your mother will give you the secrets of sexual indecency towards pleasuring a mare, I will teach you first hoof on the best ways a mare is to be done with”.

Big Macintosh watched his mother spread apart her developed leg muscles. Behind her large hard working thighs was a hole where a pulsating flesh bead went in and out of her. Big Mac was still a young stallion, but even he couldn’t deny the scent of a mare in heat. His penis raised up and stretched out in full mass. He never experienced such a sensation before, but he enjoyed the stimulation of it.

“Thats good Big Mac, now come over here and start with some foreplay, make sure to raise out your tongue and don’t get too horny on me or you’ll preejaculate”.

Big Macintosh raised a hoof before he stepped closer to his mother. He lowered his neck and felt the heat press against his face. His tongue slapped into her until he buried it deep into its folds. Pear Butter gave out a moan until she lowered her head aback over the crate she rested on. Her son licked in a circular rotation which caused her knees to shake.

“Thats it Big Mac, you are doing such a splendid job” she said. “I’m so proud of you, you’ll be pleasin and fuckin any mare in no time”.

Big Macintosh released his tongue from the hot squishy flesh. He got much closer and pressed his hooves on her shoulders. His long penis could be seen across her torso. It caused Pear Butter to have a red blush on her cheeks. She couldn’t believe she was about to take in that giant monster. There was no escape from the beast about to assault her. An energy came from her spine.

“Mama, is it ok if I cum inside, I want a little sister or brother after all”.

Pear Butter scratched her sons messy hair and gave a smile. She pulled in Big Mac before closing her powerful hindlegs, making his penis close in to her chest.

“You better take care of your foal, Big Macintosh, its a big responsibility” said Pear Butter.

Big Mac aimed at her open entrance and readied his thrust to go deep in. His need to procreate became stronger than the exhaustion he had from working the fields.

“Its okay ma, I’ll be a good daddy/sibling to our foal!”

He then slammed it inside, the hot tightness was met with a powerful friction that made Big Mac moan. Pear Butter did the same as her tongue went out of the mouth. Noticing such an obscene gesture, Big Mac raised himself up with his powerful hooves and licked her tongue. They felt them lick against each other.

A red hoof smacked the mother’s backside making it jiggle from the force. Big Macintosh slammed deeper into her folds. They grasped each other with great hunger in their mouths. His incredible young strength felt amazing with his powerful hip thrusts. There would be no escape from the suction of their loins being touched. Their passion was met with invigorated love for the taboo of incestuous sex. With every thrust, Big Mac could feel her warmth surround and tighten himself.

Big Macintosh slammed faster to where he was ready to fire. He could feel the pressure overwhelm his crotch.

“Mama, I’m going to cum!” said Big Macintosh well deep into his mother.

Pear Butter grabbed his back and pulled him in with both hooves. He exploded into his mother, each shot of semen drenched and wet her womb. She laid back from the orgasm that flooded her insides. They both moaned at the sensation of sexual delight. And accepted each other into this new adventure.

“Wow Big Macintosh, that gave me the greatest orgasm ever, I might just get pregnant from this off the bat!” she said with deep breaths in between words.

“Isn’t that great momma, I think we should name her Applejack!” said Big Macintosh.

“Great, and I already killed your father, so we can make love for all eternity for all we care!” she said.

“Wait what, did you say mama?” said Big Macintosh.

Pear Butter pulled her son in to her face for a kiss.

“I killed your father, his corpse is right behind the bed of hay we just had sex at” she said with a gleeful tone.

Big Macintosh turned his head towards the side of the bed to find his father. He had a axe embedded in his skull with a pool of blood surrounding his body. He laid there limp with a huge frown and wide open eyes.

“Uh, mama, what!?” said Big Macintosh with a whimper.

Her voice turned deep, a demonic sound came from her.

“If you tell anypony, I’ll rip off your stomach and spread out your organs over the trees for them to eat” she said.

Big Macintosh frowned.
–

“Ah Big Mac, hold my hoof, I can not take this pain!”

Pear Butter sat in the hay and she was crowning, the top of the head was pushing forward. Big Macintosh noticed the head and in one full swipe, pulled the foal out with one force of his hoof.

“Ah thank you Big Mac, I’m glad to have such a beautiful son as my husband” she said.

The foal burbled and shook which cried as it was born.

“Its a girl momma, aren’t you proud” he said.

Big Macintosh placed the foal in her hooves, she rested after such hardwork.

“Don’t worry momma, she will be in good hooves, rest in peace” he said.

“Wait wha-?” said Pear Butter.

In one fast swipe, Big Macintosh slammed a samurai sword into her brain. It cleaved her head in half which showed pink brain matter and blood splattered out over the foal. Again Big Mac slammed the blade with a force that split her skull in half.

Applejack the foal burbled in delight as the wet red stuff covered her body.

“And she’ll be safe from you” said Big Macintosh. “Now you’ll never kill again”.

Big Macintosh cried and dropped the sword to the ground. He picked up Applejack from her decrepit corpse and left it to rot.

“And thats how my parents died” said Applebloom, with Sweetie Belle and Scootaloo sitting next to her around a campfire.

“Wow that sounds traumatizing” said Scootaloo. “I wonder how he covered up the bodies”.

“Its okay, my mom was a serial killer, so its no big deal” she said. “As for the bodies, they are being kept in the family barn as a reminder to not become like that”.

“Wait a minute, if Big Macintosh killed your “mom” while giving birth to Applejack, then she isn’t your mom, she is your grandmother, and you are a second generation inbred” said Sweetie Belle.

“No it can’t be, it isn’t true, lalala stop lying” said Applebloom while she covered her ears.

They all laughed at their joke together. Applebloom gave a sheepish laugh as they did.

The end.
