Big Mac Accidently Makes a Harem

Big Macintosh was almost done with the day's work. Applejack, although still processing what she saw yesterday, was selling the apples today all he needed to do was the deliveries. He walked through the streets of Ponyville, several of the filly population tended to stare as he passed. It wasn't too bad of a day, a few clouds here but overall a nice day. Mac's blank stare was enough to keep fillies from trying to talk with him, although they seemed to be more interested in his cutie mark. "It is a pretty cool mark if I do say so myself." Big Mac thought sticking his chest out more and flaring his nostrils. A few mares "oohed" at this gesture.
In the center of town stood a gingerbread house, in reality it's just a bakery/house. Sugar Cube Corner is what it was called. Contrary to popular belief the building is not edible and those who try to see if the rumors are true get a stern yelling by the owners, Mr. and Mrs. Cake, and week long ban from their confectionaries. Unfortunately today Big Mac was only here to deliver apples for next week's apple turnover specials.
Big Mac made his way to the back door of the store and knocked. Upon contact with contact between his hoof and wood, a pink pony popped out of a nearby window.
"HI!"
"Whah!" Yelled Macintosh stumbling back a meter or two before tripping on his wagon. Once his daze was gone he glared at the pink party pony halfway out the window.
"Oops. Sorry Mackey Wackey." Said Pinkie Pie with a slight chuckle. Mac let out a sigh.
"It's okay Miz Pie y'all didn't mean anything by it." Said Mac.
"Of course I didn't! I would never hurt a friend on purpose! I just read that you were coming so I thought I'd surprise you! Like this one time"
"Wait. What do ya mean by "read I was coming"?" Mac interjected.
"Oh silly, Mackey Wackey, in the paragraphs above."
"Pardon?"
"Most ponies can't see them so its okay. Anyways the Cakes left to have a picnic in the park and I'm in charge so go ahead and bring them apples in." Stated Pinkie Pie in a upbeat tone.
"Well, great" thought Big Mac. It's not that he dislikes anypony but Pinkie and him were just polar opposites. He would be the stallion in the corner of her parties just wanting to go home and she was that cute mare everypony liked, dancing and talking with everyone. She was nice but he could never keep a conversation with her (like most ponies actually but especially with her). Mac decided to try and get in and out as fast as he could. He proceeded to bring in the baskets of apples at a rather fast pace finishing in just about six minutes.
"Thanks Mackey money's next to the mixer!" Pinkie Pie shouted. Big Mac retrieved the payment and tucked it into his yolk for safe keeping. He proceeded to begin walk out the back door till he noticed three balloons shaking widely on a pink canvas. It was Pinkie's flank hanging half way in the kitchen through the window she popped out of.
"Umm...Miz Pie"
"Yes Mackey! Was it not enough? Oh shoot one sec. Let me just." The flailing of limbs confirmed his suspicions, she was stuck.
"Nnope. The payment was fine,but do ya'll need some help?" Big Mac asked.
"Oh yes pretty please with chimmy cherry changa on top." Pinkie said with a wiggle of her plot. Macintosh, being the gentlecolt he is, averted his eyes. He walked closer and held her tail in his mouth and began to pull. After a strenuous minute he stopped and went to the other side and tried pulling on her front hooves...no luck.
"Well shoots, I guess I could buck ya out." Macintosh suggested.
"Oh Mackey, were not at that part of the story yet." Pinkie blushed and waved a hoof at Big Mac
"Pardon?"
"Oh nothing, we can't do that. I've already caused too much damage this week and if I break something while the Cakes are away they'll never trust me with the shop again, and that absolutely totally cannot happen!" Pinkie shouted out," There's some butter in the kitchen, hoof me a stick and I'll butter myself up here you butter me up from inside. Okey Dokey?"
"Eeyup." Macintosh went back inside to get the butter. Once found, he gave a stick to Pinkie and proceeded to butter up the pastry chef from the inside.
"He he! Wait Mackey stop your tickling me!" Pinkie let out between giggles.
"Sorry, Miz Pie, it's the only way" Mac replied and continued, there were sounds of giggle coming from the other side but he didn't stop. He slowly started realizing her cotton candy tail was slowly beginning to rise and her plot was getting especially oiled. He averted his eyes again but the tail begun to tickle at his nether regions.
"Gulp."
"S-something w-w-wrong Mackey?" Pinkie Pie asked repressing the urge to laugh.
"Nnope!" Macintosh quickly responded and picking up pace slightly. His cock was now fully exposed and he was thinking of the worst possible things to make his erection go away: mathematics, legal documents about the farm, and Granny in her girdle who on Hearth's Warming Eve got so drunk that she thought he was grandpa.
"Oh I think I'm loose enough to" Oh no is all Big Mac had time to think as a pink blur flew back and land right on his, you guessed it, his colthood.
"Oh my goodness! I was so buttered up that your meat slid straight into my oven!" Exclaimed Pinkie looking down, "well...since its already in there."
Big Mac was shocked as Pinkie began to slowly grind.
"I'll just have to "pound" this meat till it turns soft. Make sure to "beat" my "eggs" with that rod of yours. Oooh. My oven's really heating up now." Pinkie was letting out a pun with ever downward thrust. Well at least she didn't make a reference to his nickname.
"I know they say you're "BIG" but you really do scrape the bottom of the barrel with your cock" Damn it.
This continued for about ten minutes till suddenly Pinkie Pie screamed,
"Oh yes. Turn me into a cream pie!" And so Macintosh filled he full of his cream with a satisfied grunt.
Pinkie fell onto the barrel of his chest.
"That was great Mackey."
"Eeyup."
"Hey, do you really think we can't hold a conversations?"
"How'd ya know that?"
"I read it and you know I've always noticed you in the corner of my parties, but I was always too nervous to talk to you. I know crazy right but maybe at the next one you can be the one I dance with. Is that okay Mackey?" Pinkie Pie seemed genuine to the shock of Macintosh.
"Eeyup" you smooth devil Big Mac.
"Really! Oh boy! Thank you Mackey Wackey!" Pinkie with gleeful jump. Unfortunately this moment was short lived as the chimes to the entrance of the bakery rang
"We're back, Pinkie!" Mrs. Cake shouted from the counter.
"Okay! Be out in a second!" Pinkie yelled back, "you better get out of here Mackey." She whispered to Macintosh "I'll send you an invite to my next party sometime this week."
"Eeyup" as he tipped hoofed through the back surprisingly quietly for someone his size. Well, today was a good day for Macintosh all left to do was get home and wash off all this butter.
