Big Mac smirked as he firmly secured the last knot with a sharp tug. Below him, lying helplessly on a bed of straw bales was his younger sister Applejack, stripped naked and bound tight. Her brilliant green eyes glaring up at him as she struggled against her bonds to free herself but Big Mac knew his way around rope better than her. She ignored the sharp pokes in her back caused by the sharp straw beneath her as she tried to shout angrily at her brother to free her but her panties stuffed in her mouth secured with tape left her unable to do much more than emit a muffled cry.
“Ah hope ya are ready for this.” Big Mac said as he slowly stripped his own shirt off and unbuttoned his pants.
Applejack momentarily ceased her struggles as she watched her brother undress and her eyes locked onto the bulge hidden by his boxers. Within seconds what lay hidden underneath was revealed and she finally lay eyes on her own brother’s semi-erect penis. Her mind raced as her emotions were overwhelmed with confusion and panic, but Big Macintosh had only one goal in mind, and he was about to finally fulfill that achievement today.
Stepping forward, Big Mac closed the gap between himself and his helpless sibling. He roughly grabbed a portion of the yards of rope that bound Applejack’s body and flipped her over so she was now on her stomach. Even with the rough treatment Applejack was still able to rile up enough strength to attempt to fight back, but as she tried to kick out behind her Big Mac retaliated by delivering a heavy hand to her exposed rear.
The force of Big Mac’s slap caused Applejack to scream out into her gag but all Big Mac heard was yet another muffled cry. He was confident that her attempts to call for help didn’t make it outside the barn’s heavy wooden walls, but even if it did nopony else was on the farm for the next few days. He was alone with his sister, and he intended to savor every second he had with her and get to know her body better than anypony else had or ever would. Wanting to hear her cry out again, he used one hand to yank sharply on Applejack’s tail while he delivered another sharp blow to her ass. He was rewarded with another muffled cry from his helpless victim as well as a surprising glimmer of wetness starting to develop around her crotch.
“Ya like that, huh?” he asked as he roughly shoved two fingers into Applejack’s moistened cunt.
Applejack could only grunt from the sudden violation of her body. Her body squirmed as Big Mac toyed with her body, his fingers twisting and turning inside of her. It wasn’t until her body subconsciously thrust back against Big Mac’s hand that the dominating red stallion finally stopped and withdrew his fingers from his sister’s body.
Applejack found herself surprisingly out of breath from the quick and sudden penetration, not to mention confused by what her body had just done. She wanted nothing more to break free and escape, but something inside her wanted to stay and submit. ’But... we can’t. We’re siblings!’ she thought.
Applejack’s train of thought was soon interrupted by the touch of something hot right against her crotch. Trying her best to look behind her, her eyes went wide in shock as she saw Big Mac lining himself up and rubbing the tip of his rock hard cock against her slick lower lips. Sanity won over finally and she began to struggle once again, but thanks to Big Mac’s tight rope work she wasn’t going anywhere. All she managed to do was increase Big Mac’s own pleasure due to her crotch rubbing side to side against his rod.
The older brother let his younger sister struggle and squirm without resistance beneath him. When she finally tired out and began to give in to her fate he grabbed a portion of the rope binding her body for leverage and thrust his hips forward. Applejack let out yet another muffled shriek as Big Mac’s cock forcefully made its way into her pussy, steadily splitting her open and stuffing her tight hole. Big Mac’s cock was just over the average length but was definitely thicker than most other stallions, causing Applejack to grit her teeth as her body was forced to accept her brother’s penis inside of her. Big Mac on the other hoof enjoyed the hot, tight hole of his sister gripping his rod as he sank deeper and deeper inside of her, keeping just enough pressure to continue forward in one long, slow stroke until he finally bottomed out against her cervix. Only once the tip of his cock met her deepest parts did he begin to move his own hips back and forth to begin breeding with his own kin.
“Ya sure got a tight little pussy there, sis.” he said as his cock sunk deep into her body once again. “Ah told ya you’d enjoy this, don’t ya?”
Applejack nodded her head in agreement as her body continued to be ravished by her brother. The presence of more of her own juices confirmed that she was indeed enjoying the rough treatment or being bound and fucked by her own family member; the hard thrusts inside of her accompanied by the rough barn rope binding her body and the prickling stabs of straw into her sensitive breasts all coming together and building inside of her.
The groans of both Apple siblings combined with the wet sounds of sex barely penetrated the walls of the barn, but for one pony hiding in the loft of the barn everything could be heard crystal clear. With her phone recording the events going on below her, Rainbow Dash tried her best to keep her recording as steady as possible while her other hand quickly shoved down her shorts and panties. She managed to stifle her own moan as she watched her best friend get ravaged by her own brother, her fingers quickly getting to work on her own body. However, she was unable to stop herself from letting out a gasp of surprise as she heard Big Mac nearing his own orgasm.
“Ready for me to cum inside ya?” he asked Applejack.
The female farm pony shook her head no but Big Mac wasn't concerned with what she wanted; he knew what he was going to do. "Ah'm gonna cum inside ya and fill you with my seed." he said. "Won't be long 'fore ah knock ya u-"
“Okay, enough! Stop! Stop!”
Scootaloo barely managed to avoid Apple Bloom’s desperate lunge forward to swipe the small stack of paper in her hand, nearly toppling off of Sweetie Belle’s bed. “Hey, hold on, Apple Bloom. This was just getting to the good part.” she protested.
“No it’s not! Seriously, how can you NOT be grossed out by this?” Apple Bloom exclaimed. “I mean, Rainbow Dash writing about AJ and Big Mac fucking is bad enough, but for her to include herself in the story WATCHING them?! And did she really need to keep on mentionin' that they're siblings so much?”
Scootaloo shrugged. “What? Watching two ponies fuck is kinda hot. Besides, Big Mac is a hunk of a stallion, and AJ is pretty good looking too.”
Apple Bloom found herself at a loss for words and looked to her other friend for help. All three of them were sitting on top of Sweetie Belle’s bed to hear the ‘great stories’ Scootaloo had found hidden in Rainbow Dash’s room, but now Apple Bloom was regretting the decision. Sweetie Belle simply sighed and shook her head. “Well, I guess we now know why Rainbow Dash wanted those writing tips from AK Yearling.” Sweetie Belle simply stated.
Apple Bloom groaned and shook her head in defeat. “So this story Rainbow Dash wrote, how long does it go on for?”
Scootaloo shuffled the pages in her hand. “Well, this one is about eight pages long. Gets kinda kinky near the end when they're both in the horse stable-”
“Don’t you DARE read any more of that.” Apple Bloom threatened.
Scootaloo shrugged again. “Well, there are some others I found earlier. There’s one about Rainbow and Applejack we can swit-“
“No.”
“Then how about one about Big Mac and Miss Cherilee-“
“No.”
“Then how about Big Mac and… nevermind.”
Apple Bloom’s eyebrow raised in suspicion as Scootaloo’s face went red. “Let me see that.” she said.
Scootaloo shook her head, not wanting to risk making her friend absolutely lose it if she saw that specific piece. “Nuh-uh.” she said, hiding the pages in question behind her back.
“Give it!” Apple Bloom said, lunging forward again.
Scootaloo managed to keep the papers out of Apple Bloom’s reach but nearly fell off the bed again. Apple Bloom pounced on the opportunity and wrapped her arms tightly around Scootaloo’s waist to stop her from running off.
“Quick, Sweetie Belle, grab them for me!” Apple Bloom said as she began tickling the young pegasus to try to loosen her grasp on the papers.
“No, no! Get her off!” Scootaloo managed to cry between gasps of laughter.
Sweetie Belle remained in her spot, torn between wanting to find out just what Rainbow Dash had written or trying to put Dash’s secret perverted writings out of mind. However, a sharp knock at her bedroom door caused everypony to pause just before as Rarity poked her head into the room.
“Enough roughhousing, you three.” she said firmly. “It’s getting late anyway, you should be getting to bed soon. Oh, and Sweetie Belle, father just arrived from the train station and is staying over tonight.”
Hondo quickly waved hi before stifling a yawn as he passed Sweetie Belle’s room, rolling a suit case behind him. Sweetie Belle waved back before Rarity bid them goodnight and shut the door and headed back to her own room. Once the three fillies were alone once more, Apple Bloom and Scootaloo looked over at Sweetie Belle.
“So… your dad is staying the night?” Apple Bloom asked.
“And isn’t the guest room currently being recarpeted and repainted?” Scootaloo joined in.
A simple nod from Sweetie Belle had Scootaloo dashing for the door.
“What are you doing?” Sweetie Belle hissed.
“He was headed for Rarity’s room, wasn’t he? I gotta see this.” she said with her wings fluttering in excitement before she ducked into the hallway
Sweetie Belle’s mouth dropped as Apple Bloom also rose and headed quietly made her way to the door and turned towards Rarity’s room. “Apple Bloom! What the fuck?” she hissed.
Apple Bloom looked back and shrugged sheepishly. “Well, I mean, they’re not related to me.” she said before going off to join Scootaloo.
