Later that evening the full moon had risen and things finally began to slow down on the farm. It had been one of the more tedious days of work but again it was conquered by the Apple Family. As usual, Big McIntosh was up into the night when all of the other ponies had retired for the night. There wasn’t anything to do tonight, so he retreated to one of his most favorite spots on the farm and settled there to pursue one of his most favorite hobbies: reading. Some night when he hadn’t much or anything to do, Big McIntosh would sit up in the barn and lose himself in an adventure book or let his heart be warmed by a romance novel. Though slow with words at first, he was proud to say that he was entirely self-taught and could fly through books (though he preferred to read slowly and soak it all in).

He would die of embarrassment if anypony, especially Applejack or one of her friends found out. It wasn’t them having the knowledge of him reading that bothered him, but it was the content of the books that did. Just now, Big McIntosh was flipping through a passionate romance novel; it was sweet and yet arousing at the same time. Interestingly enough, the book had started out rather boringly and Big McIntosh honestly felt as though he might not like it. However, as he progressed through it, things only seemed to get better and better. First, there was the chance meeting between the two lovers, and then there was the build-up of a friendship which then led to a passionate one night stand and then on to a dangerous forbidden love which again seemed to be leading up to another passionate night for the two lovers.

Just as he turned the page though, Big McIntosh was forced to slam the book closed and throw it under a stack of hay with his other tomes. A sound startled him and Big Mac quickly jumped up and tried to make it look as though he was doing something, anything else. He stopped when he heard a familiar voice say, “What're ya so jumpy for?” He turned to see his sister, Applejack, with a smirk on her face. In his usual manner, especially when she picked on him, Big Mac ignored her and started to tinker with some of the ropes and small machines hanging on the wall. Again though, he stopped when he felt something touch his side. He looked slightly down and back to see Applejack leaned on his side, smiling now. “Oh, ya know I'm only foolin'.”

Big Mac smiled back to let her know that he knew she was only messing with him and then went back to messing with the items on the wall, still trying to make it look as though he had nothing to hide. Once more though, he was forced to stop, but this time by an unexpected hug from his sister; it was so spontaneous and so tight that it totally took him by surprise. However he, as any brother would do, slowly wrapped his foreleg around her and then lowered his head so that it would be closer to hers, embracing her back. In the midst of it though, when he opened his eyes, he noticed that she was wearing a saddle. It was absolutely beautiful, light brown leather with green stitching. He felt it odd that she was wearing a saddle, especially at night and here on the farm. Applejack never wore a saddle unless she was going to some fancy place or to some special event with her friends, and even then she always seemed peeved to wear one. Regardless though, he couldn't help but notice how nicely it contoured her body and how beautiful it made her.

He quickly looked away though when he felt her start to pull away from him; he didn't want her notice that he'd been staring. When she backed away from him though, her eyes met his and that, coupled with the unexpected hug, just made things too awkward for the gentle stallion. With a shaky hoof Big McIntosh went back to fiddling with the things on the wall, tried to anyway. Once more, Applejack stopped him, this time by saying, “I'm sorry, I'm sorry. Ya don't have to be nervous brother.” She smiled at him and then gave him some seconds to calm down. Afterwards though, her whole demeanor changed and her eyebrows relocated in a sexy way, her eyelashes batted, and a rather sensual smile spread across her face. She walked slowly closer to him and said, “You know I appreciate you Big McIntosh. You know I do. You know how big and strong and...” she reared up and propped herself on his shoulders for support, face to face with him and continued, “attractive I think you are.”

Big McIntosh looked as though he wanted to say something, but Applejack wouldn't allow him the chance. She slowly brought her head, her lips, closer to his and all he was able to shyly get out was, “What are you...” she planted her lips on his though and then cut him off.

This kiss wasn't your run-of-the-mill kiss in any way. No, this kiss was long and this kiss was passionate; this kiss was sexual. Big Mac wanted to pull away so bad, but he just couldn't. Instead, he closed his eyes and he kissed her right back without meaning to. Finally though, she pulled away from him, breathing heavily. Ashamed at what he had done, Big McIntosh once again began to quiver and turned to the wall of ropes and machinery for a way out. Applejack stopped him though and turned his head towards her. “Don't act like you don't like it,” she gently demanded, “You know you love it. You know you love it and you want it as much as I do.” His eyes darted all around, away from hers. “Don't act like that night ever happened.”

At the mention of that night almost one and a half years ago, a lump formed in Big Mac's throat and beads of sweat began to form on his head. When that whole accursed event had happened, and when it had ended, both he and his sister promised and swore to each other that they would never mention it again. Now though, it was being mentioned and Big McIntosh was being forced to relive a night which should have never, ever happened.

Many nights ago, on a night similar to the one that was in the present time, Big McIntosh and Applejack were alone in the barn. It had started out innocently enough; big brother and little sister up after their bedtime, playing out in the barn. It wasn't like there was a massive age difference, not even a physical one as neither of them had really changed at all, but still, it had been incestuous. After some friendly wrestling, Applejack had accidentally landed on top of Big Mac and her lips had accidentally landed on his. Of course, both of them pulled away from each other and blushed. Only, unlike most would do, there was no hasty dismount or embarassed mumbling. In fact, they both kissed each other back; Big McIntosh's head went up just as Applejack's went down. He wrapped his foreleg around her back and she stroked his chest with her hoof. One thing lead to another and then another until eventually the two of them were left laying beside each other, breathing heavily and sweating just as badly, the both of them reflecting on what they had just done and uncertain really of how to feel about it. Finally though, a secret pact was made between the two to carry this incident to their graves and to never mention it, not even to each other, ever again. However, it would seem that the part about them never actually doing it again was never mentioned...

Recounting the experience over and over again in his head, Big McIntosh felt as though he wanted to break down inside. Applejack sensed this though and she approached him and kissed him once more. When finished, she remained wrapped around him and whispered in his ear. “Don't hate it, don't hide from it, and don't be scared of it,” she whispered to him, “Take me Big McIntosh. Take me and make me yours.” She kissed him briskly on the lips, but only briskly before she found herself on the ground and in the hay.

At first, she didn't know what had happened. She didn't know if he pushed her off or if she just fell or what, but it soon all became pretty clear when she looked and saw him standing over her with an erection. She smiled when she realized that her words had gotten through to him. “Come on over here cowstallion,” she said to him and then winked.

Still retaining some of his nervousness, and with a blush on his face, Big McIntosh stepped forward. He walked just a little bit past her until his back legs were almost even with her head. Applejack, laying on her side, moved forward just a little and then moved her head towards his developing erection. She kissed it softly on the sides first and then on the head, exciting him even more. After that, she licked it all around and slid just the tip of his head into her mouth. Big Mac moaned in delight and watched from between his front legs as she did what she did.

After that, as she felt him completely hard with her tongue, she slid under him and began to fellate him. It seemed to her as if he had grown a little since she had last done this, but no matter, she liked a challenge and good gag as well. She started slowly and sensually, pushing her head and her lips along and then pulling them back along his shaft. As she eventually got used to it though, she would begin to take more and more of his penis into her mouth. Eventually, when she brought her lips back down to his head, she wrapped her wet lips tightly around his shaft and then began to slowly push her head up towards his chest and thus to the base of his penis. After what seemed like one sexy and pleasurable eternity, Big Mac let out a groan as Applejack forced all of him down her throat. Not only did she do that, but she actually held it there for a good while.

Big Mac was so big and wide that it seemed almost unfathomable that she was able to do such a thing, but still, he wasn't complaining. It felt amazing! Even though he was nowhere close to orgasm, he felt like he just wanted to bust his seed right down into her stomach it felt so good. Still holding him in his entirety in her throat, Applejack began to move just her lips back and forth quickly along the base of his penis. She felt his cock flare and bounce once in her mouth, and even though it almost made her gag, she loved it. Her eyes were starting to water so she let off of him and allowed her head to drop back down to the hay beneath her. Once he was out of her mouth, Applejack smiled to herself and then coughed a few times; she loved the feeling of his masculinity all the way down her throat. After that, and still with a smile on her face, she dried the tears from her eyes and cheeks and then kissed his shaft just one more time.

Since she was still laying down and he was still standing up, Applejack figured it might be easiest and perhaps even cute if she she slid under him. She wiggled her way up through the hay on the back until she eventually found herself face to face with her big brother. “Well howdy,” she said to him and then smiled sheepishly. They both blushed and looked away from each other, almost as if they had second thoughts. Any second thoughts that had been though, if there had been any, were cast aside when Big McIntosh kissed her. They both closed their eyes and Applejack placed her hoof lightly on the side of his cheek.

Once they finished kissing, Applejack smiled gently at him and then said once more, “Take me Big McIntosh. Take me and make me yours.”

Though he was hesitant, circumstances taken into account, Big Mac eventually lowered himself down on top of her and then slid himself inside of her. His massive size made Applejack gasp in both pain and pleasure; after all, it was only her second time. Once sure that he was inside of her totally, Big Mac began to thrust forwards and backwards slowly, careful not to hurt her. At first he kept just the very end of his penis inside of her but then he moved just a little deeper with each thrust, widening her up.

Her moist pussy felt great around his hard cock and it was all he could do to resist the temptation to just thrust all the way inside of her. He kept telling himself that his moment would come, but until then he would have to make things easy for her at first. With each and every thrust that he took Applejack let out a moan or a whimper. She loved the feeling of him inside of her, and couldn't resist reaching her hoof down and rubbing the top of her vagina for a few moments. Some of her juices got onto her hoof, so she reached up and dried it off by jerking Big Mac off as he thrusted deeper and deeper.

Soon after that though, Applejack was forced to lay back down flat and slam her hoof back down at her side, both out of passion and for support. Big Mac slammed his cock all the way inside of her, and just one thrust was enough to force her to orgasm. Her juices shot out all over him, all over her, and all over the place! Strong as ever though, Applejack remained buckled in for him to finish up.

He began to thrust faster and faster, still deep inside of her and it was all Applejack could do to hold back orgasm again! She looked up at him afterwards though, and saw that his head was raised high in the air and beads of sweat were all over him. She knew that he must be close to orgasm so she reached up and stroked his chest gently with her hoof and then began to cheer him on.

Breathing heavily and still rubbing his chest, she told him, “Come on cowstallion, ya know you want it. Ya know you wanna make me all messy.”

Big Mac just couldn't deny or ignore words like that, and sure enough after a few more thrusts he felt like he was going to cum. As quickly as he could, though just barely, he pulled out of her, stood himself up, and then released. Applejack closed her eyes to save them from the massive spray of semen that came right for her face and upper chest; it was too late for the little bit of cum that was in her pussy. Her big brother came quite a lot so she had to keep them closed for what seemed like an eternity, but to keep herself preoccupied she licked all of the sperm off that was in reach of her tongue and then rubbed the rest into her coat.

Finally, when she felt the last few droplets drip from his penis, Applejack opened her eyes and she watched his cock retract up into his sheath. He stepped off of her after it was fully retracted and blushed deeply as soon as he saw her face. Thinking quickly, he grabbed a towel from the nearby storage pantry and brought it over to her. She thanked him and then took it out of his muzzle and began to clean herself off, starting at the face. Once she was done up there and began to move down the rest of her body, she laughed under her breath and then said, “Hoo-Wee!! That was some ride big brother!”

In his trademark reply, Big Mac smiled at her and agreed, “Eeyup.” He remained silent as he watched her dry his seed off and then toss the towel aside. After that, he helped stand her up and then brushed the hay off of her.

“Thank ya,” she told him as she too brushed some pieces of hay off of herself. Big McIntosh merely nodded his head and then continued to brush her off, determined to get each and every little piece of hay off of her. She wouldn't let him though, and only chuckled and then moved away from him. “Don't worry about it Big Mac,” she said, “I'll go take a bath and look good as new.” He looked as though he was going to say something to her, but she stopped him with a wink and said, “Awful shame ya can't join me.” She walked forward and gave him a kiss on the cheek. “Good night,” she said and then turned, only to bump her rump against him sexually and then walk off.

Left alone in the barn, Big Mac watched his sister walk out into the night and then ascend the hill up to the house. He watched her go all the way up to the house, his eyes partly on her and partly on her perfect rump, and his mind too partly on her and partly on what he wanted to do with her. He shook his head though and looked down at the ground; he could feel the guilt begin to set in.

After it first happened, not only had he vowed himself to never speak about it and to try his best to forget that it had ever happened, but he also made a promise to himself that he would never, ever do it again. He loved Applejack so much and he didn't want to hurt her. He would never forgive himself if he did that. But yet here he was, breaking that vow and taking advantage of his sister once more. Not only that, but he watching her walk away from him and making it a point to stare at her butt in the process.

Big Mac watched her enter the house and then sighed. He hung his head in exasperation and confusion for a few moments and then rubbed his forehead with his hoof. He was all tired out and just felt like going to bed. Still though, he would've liked to have made some more progress with his book. He didn't really care, was too tired to care really, and just decided he would risk taking it into the house and hide it under his pillow when he got done with it.

He walked over to the haystack and sifted through it and the other books until he found the one that he had been reading before Applejack walked in on him. Taking it in his muzzle, he walked out into the barnyard and closed the big red door behind him. He looked up towards the hill and saw that all the lights in the house were off except for in the bathroom, meaning that he should be able to sneak in without anypony seeing him or his precious book. With a lack of energy in his step, whether it be from exhaustion or guilt, Big Mac proceeded up the hill and then entered into the house. He climbed the stairs and walked through the dark hallway as quietly as he could. As he was walking though, he couldn't help but notice that the bathroom was open when he walked past it. Something told him that he wanted to peek inside and watch his sister wash herself off; observe her while she was all wet and vulnerable. He resisted what he felt was a sick temptation though and continued to walk quietly until he reached his room.

Once in there, he closed the door and locked it. He didn't really know why, but for some strange reason tonight he just felt safer with the door locked. Big McIntosh laid down on the bed and situated himself so that he was comfortable and then put the book down on the pillow and flipped it open, and then, using the light of the moon as his guide, began to read. For some reason though, he just couldn't get into it. He tried and he tried but then he just gave up. He shut the cover of the book and then slid it under his pillow and made sure that it was hidden from any eyes that might pry into his room.

He flipped over onto his side after that and stared out of the window at the moon. It certainly was beautiful this night, there was no denying that. Eventually though, he bored of that and flipped over onto his back after he drew the shades. Left in the dark and with his thoughts, Big Mac thought of everything that had just happened and everything that had gone through his mind in the past few minutes. He hated it but he loved it, he was sick of it but he desired it, and he wanted to forget everything that had happened but then he wanted to explore his desires.

Big Mac sighed as all of these thoughts raced through his mind. He turned his head left on the pillow and then closed his eyes, hoping that when he went to bed the thoughts and his feeling would go away, at least for a little while. Unfortunately for him though, they didn't. Soon even, he heard the door to the bathroom close and then he heard hoofsteps coming this way; they stopped in front of his room for a moment or two but then proceeded on down the hallway and then entered into the room next to his. His eyes had opened when she stopped in front of his room, so he closed them back and again let his head fall to the left. So it hadn't been the best day for him, but it certainly hadn't been the worst. He felt as though he slacked this morning; he felt pretty bad about that. He had sex with his own sister; he felt terrible about that. Well, at least another day had gone by without anypony finding out that he liked to read.
