Three Apples and a Cowboy
Applecest
"That ain't how you set a table, Mac!" Applejack warned, putting down her tray and walking over to the wooden bench that her brother was completely failing to prepare. "Y'all should know better than this."
"Eenope."
Big Macintosh was attempting to set out the Apple Family Picnic, but unfortunately his body was built for bucking more than waiting on tables.
"Do I really need to show you how it's done, big bro?"
"Eeyup."
Applejack sighed. She had other things that needed doing before the picnic, which the entire extended family would be attending. They'd be arriving in under an hour, and Big Mac really wanted to do this now?
Applejack jumped up onto the table and spread her legs. "Think you can set this?" she asked with a grin.
"Eeyup."
Big Mac grinned - his body was built for bucking, not for waiting on tables. He began to bounce up and down in anticipation, slapping his giant marshmallow horsecock against his belly with a sickening series of slaps. Before long, his fleshy blade was completely unsheathed, and the noble steed charged at the table, dropping a leg to either side of Applejack's body.
Wiggling slightly, he felt the head of his giant penis press against his sister's tight hole. Without hesitation, he thrust forward, pushing himself inside.
"No, Mac, not there!" Applejack shouted as Big Macintosh penetrated the wrong hole, sending a shiver of pain through her body. "Y'all can't do nothing right!"
Big Macintosh pouted, and pulled out. Second time lucky. Aligning himself with more care this time, he set his candy pony rod against Applejack's tail hole, her preferred entrance point, and slowly slid himself inside, using her own syrup to lubricate his path. Applejack moaned unreservedly as Big Mac's unstoppable rod slammed against her like a 10 tonne train of terrific sexual energy.
"Oh, Big Mac, I guess I know why they call you big!" Applejack yelped, "It's because your penis has to be seen to be believed!"
Big Mac took the compliment, chirping "Eeyup" as he hilted his sweet rod once again, gasping as his manliness was completely engulfed by his own sister's pussy!!
"Big Macintosh, this is wrong!" Applebloom yelled from across the field, shocked at her brother's actions. "I thought you said I could be next because I am a big pony!"
"Eenope!" Big Macintosh groaned back, still holding himself against the table while he repeatedly railed his relative. Applejack lay against the table, gritting her teeth as her pony pit was filled over and over again.
Too quickly, Big Mac felt his equine shaft begin to vibrate uncontrollably as he began to orgasm.
"Brother, no! You cannot cum into your own sister's ass!" Applejack shouted as she felt her party button begin to glow with desire and wet slickness as the first tiny spurt shot out of her brother's shaft.
That was only to be the start, however, before the true torrent began. Instants later, Macintosh's dam broke, and he let loose an unstoppable flood of delicious candy pony semen, coating Applejack's insides with a thick layer of his horsecum.
"Oh, brother, now I am all sticky on the inside! Whoever shall clean me now!" Applejack wailed, still resting and breathing tiredly against the desk.
Applebloom jumped onto the table, letting the bow in her hair blow in the wind as she pushed Big Mac off the bench and onto the floor. "I can fix you, sister! I shall suck the problems away!"
Applebloom thought that maybe the next few minutes could show her her special talent, as she pushed Applejack onto her back and stared at her task. Applejack's giant futa penis flopped upwards, already hard from the rough fucking she'd received.
"Sister, I can't believe riding your own brother's cock has made your own penis grow so large!!" she exclaimed, before climbing onto Applejack's body and starting to lick the futa hose. Each lick made it vibrate faster and faster, until Applebloom could make it play little songs by alternately licking it and holding it tight, to make it vibrate slower and faster.
Undeterred by her new musical instrument, Applebloom started to shove the gigantic length into her mouth, taking it as deep into her throat as she could. Even just from inserting it, Applejack's candy futa marshmallow precum flowed freely.
"Sist-w! I cnnt blv u so roused by stsr blwjb!" Applebloom choked around her sister's own penis, lifting her legs off of Applejack's body so gravity could pull her further along her sister's shaft, letting the tip of it penetrate into her stomach.
Applebloom began to wiggle her legs to pull herself from side to side, finding a rhythm that let her become a metronome on her sister's cock, pulling it to the left, and to the right, and to the left, and to the right, with such precise timing it could have been used in a musical performance.
Unfortunately, Apple Family Illiteracy had thwarted them yet again. Their family hadn't been arriving in an hour, they'd been arriving in ten minutes!
"What is going on here??" Apple Fritter gasped as she and the rest of the Apple family walked into the field. "Our own cousin is engaged in an INCESTUOUS SEX RING!!"
"And Applejack is there too!" Braeburn exclaimed.
The flower sisters fainted, because they were also in attendance.
"Eeyup!" Big Mac exclaimed, as the shame of discovery drove Applejack over the edge, her giant futa hose expanding as she shot stream after stream of candy horse juices into her sister, increasing the pressure in her stomach until it could take no more, and a Applebloom was launched off the end of her penis like a bottle rocket, landing in a nearby tree.
Applejack hiccuped. "Family! I am so glad you are all here! How would you like to begin the celebration??" she asked.
"But Applejack, we all know that you are in an INCESTUOUS LOVE TRIANGLE, our family can never be the same!"
And the whole incident would be called Applegate for generations to come. Celestia would outlaw inbreeding the year later, and unfortunately have to arrest both her and Luna on unrelated charges of public indecency. Twilight Sparkle, a source close to the family, would report that Applejack was driven to drink after the incident, drinking perhaps 5 or 6 glasses of apple juice each and every day. Rainbow Dash, a close friend and informant would report that Big Mac really wasn't all that much, and she'd seen bigger back in Cloudsdale - but you couldn't expect accuracy from hill billies anyway.
