As expected the previous night, when the Apple Family woke up there was no breakfast and the hard work started as soon as they woke up. Applejack and Applebloom went back to practicing for the festivities (though they would be given a few hours off before the game started), Granny Smith went to practice on her speech a little more and arrange things up on the stage, and then Big McIntosh went back to checking things over. The games started at noon and that only gave him a few hours to make sure that everything was perfect and that there would be no screw-ups on their part.

Thankfully enough, everything seemed to be in order and Big Mac only had to do a couple of things that he had missed before. Otherwise, he spent the rest of the time making sure that everything was loaded up at the stand and was ready to sell. After all of the fresh pies and cobblers and candies were stocked up, Big Mac spent the rest of his time isolated in the barn and reading.

Before long though, he was forced to close his book and dash out to the front stage that had been set up as the games began. It seemed like it had only been a few minutes, but noon was already here and there seemed to hundreds of ponies streaming onto the farm grounds. He walked up onto the stage and stood, as usual, beside Granny Smith and opposite of Applejack and Applebloom who were on the other side of her. Granny Smith began her speech by greeting all of the ponies and welcoming them to the farm. She gave a brief description of the games and of the festivities that would follow and invited them all to visit the concession stands and sign up to participate. In the midst of it though, Big McIntosh, who was standing steadfast and at attention, couldn't help but glance across Granny Smith as she spoke and over at Applejack. Apparently, his sister had the same idea. She caught his eye, smiled at him inconspicuously, and then winked at him. Big McIntosh turned his head back around slowly and stared ahead; he took a deep breath and tried to clear his mind. Today wasn't the day for him to be offtrack.

Shortly after, the formalities ended and the games began. As per the agenda, Big Mac manned the concession stand for an hour or so until he was relieved by one of the farmhands. He went off to proceed with the rest of his duties, but felt like he needed a little pit-stop before he continued on. He walked towards the restrooms located behind the stands, but before he reached his destination he noticed a familiar pony leaning against one of the wooden beams of the stands. He walked up beside her and she looked over at him, “Oh, hey Big Mac,” Rainbow Dash said and went back to watching the games.

“What are you doing up here?” Big Mac asked slowly. He didn't mean to sound rude or ungrateful of her presence, but it was unusual to see her. Rainbow Dash didn't have a sister and he had never seen her here before.

Rainbow Dash shrugged and said, “Well... I dunno really. I guess I just didn't feel like laying around.” She huffed and flipped some of her mane out of her head. She resumed watching the games and laughed when Rarity faceplanted in the mud. Big Mac knew that he really should have been going on his way, so he went to tell her goodbye. Before he could so though, Rainbow Dash, while still staring at a muddy and running Rarity stopped him. “So, I saw you go into Rarity's house the other day, and that day after that, and the day after that, and... the day after that.” She turned her head and smirked at him. Big Mac's eyes grew wide with fear as the sudden horrible realization set in on him that he was caught. His face turned red with shame and his eyes started to dart all about. Rainbow Dash sensed that she had him on the edge and smirked even harder. She elbowed him rahter hard on the shoulder and winked at him, “You know I'm only messin' around. Still though...” she turned to him, “maybe there's something that you can do for me and in exchange maybe I won't run my mouth.”

Big Mac's ears perked up. He was willing to do anything just so long as Twilight and Applejack, the rest of their friends, and Celestia only knows who else didn't find out. Still though... it was Rainbow Dash and there was no telling what she had up her sleeve. Slowly, somewhat hesitantly Big Mac looked at her and asked nervously, “What?”

Rainbow Dash walked even closer to him and began to run her hoof up and down on his chest in a sensual way. “You know,” she began, “it's amazing what you can see from up in the clouds. I got so much dirt on so many ponies here that I don't even know what do,” she revealed. Big Mac wished she would stop playing with him and just tell him what she wanted. “Anyway, what it all boils down to Mac, is that I don't appreciate you doing it with my friends.” She glared dangerously at him and Big Mac couldn't help but gulp. Rainbow Dash resumed her sensual stroking and eventually concluded, “Without cutting me in, of course.” She wrapped her forelegs around his neck slowly and then kissed him. Rainbow Dash was an excellent kisser, and so was Big McIntosh, so it was only natural that they both closed their eyes in enjoyment. She backed off him shortly afterwards. She frowned and looked off towards the track. “You know, it really sucks not being out there.” She looked back at him with a sensual smirk on her face, “Getting all worked up, and dirty, and... sweaty.”

“E...eyup,” Big Mac replied nervously and blushed. The way she had kissed him and the kinds of comments that she had been telling him were driving him insane! His penis started to become erect.

Rainbow Dash noticed this and peeked around at his side. Her eyes grew wide and she bit her bottom lip. “Jeez!” she almost exclaimed too loudly, “Not here! What? You want somepony to see us?” She took his hoof and started to drag him along, “Come on big boy, let's go to the bathroom.” Rainbow Dash dragged him into an empty stall and then closed and locked the door behind him. It was very cramped inside of the stall, especially when Big Mac's massive size was taken into account. “Now go for it” she told him and kissed him a little more.

After that, the two of them wasted no time in getting things going. They took some time adjusting around, but eventually Big Mac was able to move around so that he was sitting down on the toilet. Rainbow Dash adjusted herself so that she was able to wrap her lips around his cock and begin to blow him. The way she was calculated in how she moved her head up and down and how she seemed to know just when to use her tongue indicated to him that she had done this before, though he dare not inquire about it. Either way, he was glad it as happening. It was a pleasant break from all of the work that he had been doing anyway.

As she finished up, Rainbow Dash made it clear that the only reason she was giving him oral was because it would lube him up for what was to come. “Listen up,” she told him like a coach, “The only reason you aren't gonna be down between my legs is because of this tiny little stall.” She levitated up over him and dropped down over the back of the commode, forcing him off of it. When he was able to turn back around he saw her there standing over it with her tail cast aside and a look of readiness about her. He had to admit that she looked very beautiful... “What are you waiting for?” she asked him impatiently, snapping him out of it. Big Mac shook his head, walked forward rather timidly, and mounted her. His massively sized cock penetrated into her and she let out a gasp of pain and a delight of pleasure; sher herself wasn't entirely wet yet. “Hey,” she looked back at him, “take it easy for a little bit will ya?” He nodded and thrust into her a little. She buckled in and closed one eye in partial pain. “Then again,” she panted, “I do love a challenge.”

Big Mac continued to thrust in and out on her. At first he kept only a quarter of his penis in, but as he could feel her start to get soaking wet all around him he started to go harder and faster. Soon even, he was slamming his cock down into her as deeply as he could possibly go. It felt so amazing to Rainbow Dash and she even buckled and came twice, but she held back the screams of pleasure that she wanted so desperately to get out because it made her all the more cool and it could potentially alert somepony. As he continued to give it to her, Rainbow Dash reached back and stroked his shoulder with her hoof, showing him her appreciation.

Sensing this, he laid into her even harder and truly started to work up a sweat for the both of them. How she was so tight and wet was starting to get to him though, and he could feel himself getting closer and closer to the brink of orgasm. Everything that he was feeling, her wetness and tightness, and even the sounds of her grunts and of his balls slapping against her as went inside of her as deeply as he could all eventually got to him. He kept thrusting and thrusting until he just couldn't take it anymore. He took one final thrust and then released, some of his cum going down deep inside of her pussy. Her eyes widened in surprise, albeit pleasant, and she moan in pleasure as she felt him start to fill her up. Slow to pull out was all, Big McIntosh finally pulled his cock out of her and allowed the rest of his semen to be emptied out onto her back and into her mane.

He finally finished up from bursting his massive load, and Rainbow Dash, while only joking, said, “Aww! You idiot. Now what if somepony sees this?” She shook her mane and body quickly and droplets of Big Mac's cum went flying all about. Some of it came back onto him and Big Mac scrunched his muzzle up in disgust and dabbed some of it off with a piece of toilet paper. “Hey,” Rainbow Dash said, “give me some of that.” She took some of the toilet paper from him and wiped her mane out and whatever else she could reach. “Help me out will ya?” she gave a new sheet to him and flattened her back out so that he could wipe it off for her. There was quite a bit of it that needed wiping, so they were in there for awhile. Eventually though, the finished up and Big Mac threw the paper into the toilet. Suddenly though, seeing the water in the toilet and after his massive orgasm, the original reason for why he had to come to the bathroom in the first place came rushing back on him.

Rainbow Dash seemed to be taking her sweet time in getting up and out of the stall, but the more and more that he was forced to wait, the more Big Mac couldn't hold it anymore. Acting on the impulse of having to go so desperately, he more or less jumped over the top of Rainbow Dash and, when in front of her, shoved her out of the door and slammed it shut behind her. Little did he know, there was a stallion that came out of one of the stalls located a few doors down and he stopped and stared at Rainbow Dash and the slamming door as she came stumbling out of there. Rainbow Dash blushed deeply, chuckled nervously, and waved at him slowly. She darted around the corner and waited there for him to get out.

Once alone in the stall, the sweet, sweet relief was allowed to flow over Big McIntosh as he finally was able to relieve himself. He felt pretty bad for shoving her out of the stall like he had done, but hey, when you've gotta go, you've gotta go. Before his penis fully retracted back into his sheath, he shook it a few times and then turned back around, still with some difficulty in the tiny little stall, and then exited back out to the farm. Naturally, the first thing he noticed when he exited the bathroom was that Rainbow Dash was nowhere to be found? Had she run off in anger at being tossed about like that? Had she gotten her fill of the fun and gone off to watch the games from above? Big Mac didn't really care, but he did at least want to know that she would keep her part of the deal.

Before he could do much else thinking, Rainbow Dash jumped up into the air and then pounced down onto his back, giving him what was perhaps the worst start of his life. She only chuckled at his few feeble attempts to get her off of his back and kissed him on top of the head afterwards. She stroked her hoof through his forelocks and said, “So, if ya had to go all ya had to do was tell me. That's groty! You could have like, shot off in my mouth or something.” Big Mac blushed and put his ears back in embarrassment as he realized that she was telling the truth. “Hey ya big lug,” she smacked him on the shoulder and then hopped off of his back, “you know I'm only joking.” She was standing face to face with them and they were both standing there in silence. Rainbow Dash broke the silence though, “Well, that was certainly an interesting work out. Not one of best workouts I've ever had, but definitely not the worst.” She winked at him and then turned away, only to take a few steps and then stop again. She turned towards him and continued, “I'm gonna go watch the relay race for a little bit. You can tag along if ya want, but you had better keep up.”

It sounded like a good idea to Big Mac, but then again he still had work to do. Not only that, he still didn't have his assurance that she would keep quiet about what she knew. He wanted to say something, but the words just wouldn't come to him. Luckily enough for him though, Rainbow Dash seemed to be able to read his mind.

She smirked at him and said, “Yeah, yeah. I get it, I I get it. Farmer boy with a lot of work to do. Oh well, maybe me and you could've had a little more fun.” She winked at him once more and then continued, “Seriously though big guy, I'll keep my mouth shut. Don't worry. I ain't a snitch and I don't break promises.” She smiled at him and then turned back around. “See ya around.” Rainbow Dash took a few steps away from him and then stopped and turned her head once more. “And hey, if you think I'm gonna be looking you up after this you have another thing coming!”
