Big Mac Accidently Makes a Harem

It was the day Mac feared. The day he hoped to never come. The day of his date with Fluttershy. Yes, the shy, meek Pegasus pony who loves to care for small woodland animals. The mare that would shrink in fear if he had talked to her at Miz Pie's party hoping to have one pony to talk to in the corner not dancing. Well that's what he thought before the "incident"(refer back to "the quiet ones"). Now all he could see was a disguise. A cute face that hides a dark secret.
"Hey, Bro! Who's next on the list?" Applebloom asked her brother who was sitting on the porch waiting to get picked up by..."her".
"Fluttershy."
"Oh great! You two seem like a perfect match!" The red bowed filly yelled.
"I'm scared."
"Pardon?" She asked her brother.
"I'm scared"
"Why?"
"Did Applejack tell you about what happened?" Mac looked over to his sister.
"No."
"Celestia bless her heart. Can I ask you a favor Applebloom." Mac tone dropped to a rather depressing one.
"Uh, sure."
"Can ya just hold me fer a sec?" An odd request but the little filly knew something was up and her brother needed her comfort.
"Okay, Big Mac." She hugged her brother and he back to her. The moment of comfort would not last long though as four quiet hooves hit the ground.
"Oh, I'm sorry, am I interrupting something." A meek voice broke the silence. Fluttershy had arrived to pick Big Mac up for their date.
Big Mac froze. His head slowly turned to Fluttershy. She stood there head tilted to the ground, mane covering one eye, and nudging a picnic basket she had placed on the ground. She seemed to be the way she used to be...seemed. Mac was unsure, he let go of Applebloom and told her to go inside. He watched the yellow Pegasus trying to see if she was putting up some rouse. She seemed to be the Fluttershy he had once considered dating but he remembered the time he decided to act on that feeling.
"Um...are you ready...for our...um...date?" Fluttershy gave an awkward smile.
"Erm...alright let's go." It was time. Mac may of been scared but he couldn't stand her up now. They began to walk down the trail to town. "Miz Shy, what are we doing today?"
"Oh...I thought we have a nice picnic by the river bank in the park. If that's okay with you that is." Fluttershy muttered almost inaudibly soft.
"Eeyup!" Good a nice public place if she had invited me to her cottage I might of ran for the hills.
The park was crowded today, which was technically good but they seemed to be watching them. The sight of seeing Big Mac everyday with a new mare had lost its surprise, while the mares of town were still somewhat jealous the FlutterMac combo was nice sight to behold. "Omg what a cute couple! They are a perfect match! Why wasn't Fluttershy his first choice?" Mac felt uncomfortable and to his surprise so was Fluttershy.
"Um...maybe this wasn't the best idea." She whispered to herself, she turned to Big Mac. "Maybe we should go someplace less crowded."
Less crowded meant less witnesses if she tried to pull something. But there it was again, Fluttershy seemed to be that helpless filly Mac couldn't help but protect. Although his gut told him not to he decided to suggest a terrifying alternative.
"How bout' we have a picnic next to the brook near yer cottage." What the hay was he saying.
Her ears perked up. "That's a great idea." She seemed more confident. This was not looking good had he been driven into a trap. Did she plan to act all weak in order to have him let down his defenses. He couldn't go back on her word now so he'd have to follow through. Big Mac gulped and began to sweat. After a long walk through town and somewhat secluded forest setting they arrived at Fluttershy's property.
"One sec. Let me get everything ready." She saintly laid down a blanket next to the river bed and started placing the different foods she had packed. All seemed normal. "Okay. I'm done." She smiled a huge lovable smile to Mac with what he think was the sound of a squel toy. He sat down and she began to serve him. The drink was the most suspicious of it all it seemed to bubbly.
"Miz Shy is it supposed to be this bubbly?" He eyed the drink.
"Huh, um, I don't know it's your family's cider I saved some from last cider season." Fluttershy responded calmly.
Maybe it was his imagination but what kind of fool would take the chances after the last time with this mare. "How bout a toast?!" He shouted startling Fluttershy she shrunk in a ball but lifted her glass.
"okay" she whispered, "cheers."
"To a wonderful date!" Mac shouted and to a swig but did not swallow until he saw Fluttershy swallow hers.
They proceed with the picnic. It was quite good to be honest a strange variety but Mac just focused on Fluttershy.
"Um. Mac. Can you please stop staring at me. It getting me nervous." She blushed furiously.
"Oh! Eeyup." Awkward silence.
"I'm sorry" Fluttershy broke the silence.
"Pardon?" Mac asked.
"I'm sorry about last time." The shy Pegasus continued, "I-i-I wasn't myself and I did horrible things to you."
Big Mac was surprised to say the least. She was apologizing maybe last time was a fluke of some sort, maybe she was possessed by some dead pet she once had. A female cat that died in the middle of mating season and was in heat, because that's likely. "It's okay, Miz Shy, I forgive you."
"No it's not okay!" She began to cry. "What I did was wrong. And I really hurt you. You probably hate me. But I don't want that because I love you! I love you! I loved you even before this stupid competition! I was so happy when you talked to me at Pinkie's party. A handsome kind colt talking to me it was a dream come true but I ruined it. Fluttershy your such an idiot."
Mac wrapped his arms around her. Just like Applebloom had done that morning it was his turn to comfort the pony in front of him that needed it. "Like I said. It's okay." He let his warmth flow into her fragile body. They spent the next few minutes just holding each other.
They went back to eating, they talked, laughed, and feed some passing ducks. It was an overall great date, a date that Big Mac had not expected. But all great come to a close and he needed to get back to the farm. He had given AJ the okay to hunt Fluttershy down if he didn't come back within five hours. She said she would do it if was four and her time was coming close. He wanted to stay longer but in case she wasn't kidding he should be heading out. "Miz Shy, I think we should be Darwin' this er date to a close."
"Oh do we have to?" Fluttershy said kiddingly but truly wishing for this to continue.
"I'm afraid so." He looked up to her cottage less than a twenty meters away. "Do ya'll need meh to walk you home?" He smiled.
"It would be nice." Fluttershy smiled back. They packed up the picnic spot and Macintosh escorted his filly friend to the door. She entered and faced towards Mac. "Thank you Big Mac." And kissed him on the cheek. Mac blushed.
"Have a nice day Miz Shy." He began to leave when he heard Fluttershy say something quite odd.
"Wait are you kidding? Aren't we going to have sex?!"
"Wait? What?" Mac turned around.
"That's not fair! At the end of all the other girls date you bucked them raw and hard! Why are you excluding me!?" Fluttershy stated.
"Wait how did you know that?!" Mac was getting nervous.
"I watched you. I tried to stop you but somehow you still had perfect dates! Twilight I added depressors to your food yet for some reason you guys weren't even phased! Rainbow Dash I changed the weather schedule so she would have to return to work but you bucked her in the street for everypony to enjoy! Pinkie had her original plan rained out by the storm but she's a fast decorator! And Rarity I flooded her reservation with parasprites yet you pull a romantic dinner straight out of your damn fedora!" The truth had come out.
"Ya'll tried to sabotage the other dates! How dare you! I'm out of here!" Mac was angry she hadn't change.
"Not if you want the antidote." He stopped Fluttershy stood there with a smirk. Had she...no I saw her drink it too.
"You didn't."
"Oh yes I did"
"But I saw ya'll drink it too."
"I know but I also drank the antidote while you weren't looking." She pulled out a small vile "Now, please don't let my stamina increasing meal go to waste." He thought for a second. All the food he ate were to fuel his libido. Watermelon and cucumber salad full of citrulline, fortified tofu b-12 vitamins, dark chocolate causes euphoria, even the grapes increased testosterone. It was such a weird combo that he didn't even notice the correlation between them all (by the way all that is supposedly true).
"Ya'll planned this!" Big Mac accused the yellow filly.
"Not all of it, Angel helped me out quite a bit. Anyways get in here and give me the bucking of a lifetime if you want to live." Fluttershy had gone over to the side evil once again. Big Mac had no choice but he wasn't going to go easy on her and with his training with Rarity he was ready to give her the proper punishment she deserved.
"Fine I hope ya'll are ready." Fluttershy got excited
"Oh yes! My body is ready! Show me why they call you BIG Mac!" Really if he ever finds out who gave him that nickname he would kill them.
The five hours were up and after following some leads from town AJ burst through the front door of Fluttershy's cottage. "Get off my brother ya no good huh?" Mac was finishing a vile of some sort of liquid above a what seemed to be a Pegasus covered in horse se... Never mind. "Is everything fine 'ere?" She asked the stallion.
"Eeyup let's go home." Mac walked straight out the door paying little attention to the twitching filly on the ground.
"Revenge sex is best sex." Panted a very pleased Fluttershy.
One more to go Big Mac thought to himself as he made his back. That mare in question was trying to catch up with him so they could go home together.
