It was with practised ease that Rarity managed to shoo her younger sister, Sweetie Belle, out the door of the Carousel Boutique, trusting the filly to be able to return to their parents’ place on her own. The elder sister stood outside watching Sweetie turn the corner at the end of the street, and out of sight. A warm front had set in with the passage of day to night. Rarity basked in the breeze, allowing the soft winds to lap at her fur.
Carousel Boutique was an odd fixture of Ponyville, being located almost in the town’s centre, next to the main plaza. Formerly an old town hall, Rarity had purchased the building and significantly modified it to her own tastes, turning the bottom half into her shop and studio and the top half into her household, allowing her to move out of her parents’ place. Rarity adored her parents, but she would be the first to admit to their eccentricities. Given her plans for the night, she was glad she no longer lived with them.
Speaking of plans…the object that was to occupy the ‘lion’s share’ of Rarity’s attention tonight was wandering down the street, checking to his left and right every few sections. It was a shame he was larger than his sister Applejack. After all, Applejack had looked adorable in her lion costume from last Nightmare Night, and he could make the saying literal by wearing it. Hmm, perhaps Rarity should make a similar costume for him, it could lead to some very interesting roleplay sessions-no, bad Rarity, bad! Rarity shook her head to clear her thoughts, feeling her cheeks reddening.
As Big Macintosh approached, Rarity raised an eyebrow. Even putting the lion outfit idea to the side for now, it seemed she would still be doing sewing work for him in the future. “Big Macintosh, what exactly happened to your jacket?” She asked, tut-tutting as she looked over his Ponytones outfit, assessing the damage. It wasn’t too bad, just a small hole slightly below the neckline.
“Loose nail,” Big Mac said, as if that were sufficient.
It wasn’t really to Rarity, but Rarity knew the farmpony well enough. While he wouldn’t outright refuse to elaborate like Applejack might to dodge a question while staying honest, getting more than a few words out of Big Mac when he wasn’t in one of his rare talkative bouts was more frustrating than a loose thread on her newest dress. Instead, Rarity just sighed. “Well, come in and I’ll give it a look. Just try not to damage it again in the future, you big lug,” She said in an affectionate tone, the smile on her face showing she wasn’t annoyed.
“Eeyup,” Big Mac agreed, following Rarity back in to the Carousel Boutique.
Once inside, Mac heard the click of the lock on the door behind him, and gulped nervously. Even after being in a relationship for some time, the stallion was always filled with anxiety upon realising he was alone in a house with a mare. That Rarity had been the best thing to happen to him in the last year only mildly allayed his nervousness.
“Come here, Big Mac-u~,” Rarity sang aloud, her earlier smile already turning predatory. “How am I supposed to examine your shirt if I can’t get up close?” The apple farmer gulped again, and Rarity restrained from rolling her eyes. One of Rarity’s few problems with Big Macintosh was that he was red. Seeing the other pony blush when you flirted was half the fun of flirting.
Nevertheless, Big Mac did get in closer, and lifted up his front hooves as Rarity used her magic to remove his shirt, allowing her to pull off the front sleeves as well. With the garment of clothing floating in front of her, Rarity gave it a second look-over just to be certain. “Five minutes. Five minutes and I can have it fixed, and you can even wear it home.”
“At least one of us will be able to walk around without looking awkward after,” Mac said in a rare moment of verbosity.
It took Rarity several seconds, and then…”Y-, you!” She said, her hackles rising at her utter mortification, and she could just feel her cheeks burning. Big Macintosh rarely spoke, but when he did, he could be an incredible tease. Rarity groaned, already feeling the heat in her face spreading through her body, all the way to her loins. The grin Big Mac wore didn’t help.
“You,” Rarity said in a firmer tone this time. Tossing the jacket to the side for later, she walked up to him, and then slowly sashayed past him, flicking her tail up and dragging it across his face. For Rarity, it was a learned art with fine manipulation, as her tail stroked Big Mac’s neckline, slowly rising up and softly brushing his cheeks.
Turning around, she walked up to stand beside him from his opposite flank. Nuzzling her cheek against his, Rarity looked into Mac’s eyes, pressing one ear into his barrel. She was filled with a naughty thrill at how easy it was to leave him a mess. The farmpony was practically panting, his heart beating so strongly that Rarity could hear it. Rarity loved this position. She had cuddled up to Big Mac more than a few times, the steady thuds of his heart a comforting rhythm capable of lulling her to sleep.
She kissed him. She meant for it to be a quick, chaste kiss, but found herself dueling with him as their tongues prodded at one another, trading saliva. His was of apples and, surprisingly, a hint of passionfruit. The magic of their first few kisses wasn't there, but it still left Rarity with a delightful electric tingle that she was certain left her hair on end from head to hooves. After several seconds of holding the position, she broke off the kiss, taking a couple of breaths to steady her heartbeat.
“Upstairs, you lug,” Rarity whispered, accentuating it with a smack of her hoof to Big Mac’s backside.
The red-furred stallion jumped slightly at the sudden contact, but it was a goofy expression on his face instead of surprise. Kneeling down, he looked back up at Rarity, and said, “After you, my fair lady.”
Rarity giggled, “Oh, you always know what to say to make a mare happy, Big Mac-u~.” Slowly, she hoisted herself over on top of Big Macintosh’s torso, slowly fidgeting around to get a good position. Curling her front hooves around her coltfriend’s thick withers, she attempted to link her back hooves around the underside of his sternum, failing to make it all the way. Still, satisfied that she was secure, Rarity said, “Onwards, my loyal steed! Giddyup!”
“Eeyup!” Mac agreed, rising up onto all four hooves at a speed that would’ve thrown Rarity off had she been less cautious, before he marched over and up the stairs. Even the extra weight latched around his shoulders didn’t slow him down, his hooves loudly clopping against the staircase as he walked up.
“Wheeee!” Rarity said, letting go of her exhibitions in a warm-up for the rest of the evening as she got into the moment. The top of the stairs came too soon for Rarity’s liking, and Big Mac pushed open the door to her room with a gentle tap of the head.
Macintosh walked over to the large four-poster bed, and gently shrugged Rarity off onto the soft mattress, who laid splayed out flat on her back. “Oh, darling, that was simply wonderful,” Rarity said, stretching her limbs in four separate directions, hiding absolutely nothing from view. “Wouldn’t you say?”
“Ee-eeyup,” Big Macintosh nodded his head in agreement, eyes on the prize.
“Bbbbbbbuuuuut,” Rarity turned over onto her front, crawling over until she faced over the bed, her snout touching Mac’s own, “I have an idea that would make it even better. Can you guess what it is, Big Mac-u~?”
“Ee-eenope.”
“Mmmhmm,” Rarity said salaciously, nuzzling her muzzle along Big Macintosh’s own, enjoying the warm feelings of safety and familiarity it induced, especially when Mac fell into it and nuzzled her back in turn. There were kisses, but this, this rubbing up of fur brought about an euphoria of its own to the white mare.
Breaking the contact, Rarity looked straight ahead, catching green eyes shining with interest and amusement. Opening her mouth, Rarity began to lick her lips, swirling her tongue clockwise a few times, then counterclockwise, breaking it up with the occasional smacking sound and sticking her tongue out, waggling it in the air.
Satisfied with her foreplay, Rarity lowered herself onto the floor, front hooves first, then rear, before rolling over onto her back. “Oh, woe is me, I seem to have fallen down and can’t get back up!” Rarity said in as dramatic a tone as she could, fully hamming it up. “It’s so dark, I’ll have to crawl around until I can find a way out, but oh, what’s this? I think I see a light!”
A light snort could be heard. Rarity smiled. While Big Mac would sometimes get impatient to the point of actually verbally expressing it, she knew he was as keen on the roleplay as she was.
Crawling on her back was a little bit awkward, but Rarity managed, and it was only a short distance until she found herself under the barrel of the red Earth pony stallion she had fallen head over hooves for. She smirked as she came eyes-to-eye with his erect fifth leg, and continued her histrionics, “Oh, at last! I’ve found it, the light shining in the darkness!” Finished with words, Rarity put her mouth to better use as she started to lick the length of Mac’s horsecock.
The pony who said horsecock was attached to fidgeted slightly under the sudden contact, but Rarity observed his body begin to relax. She brought her forehooves up, both to hold the long cock extended out from its sheath in place, and to begin rubbing and kneading it. It still wasn’t fully erect, and Rarity was determined to wring every last centimetre out of it. With her tongue freed up for the moment, she raised her head slightly, and took in a whiff.
Big Macintosh would never compete with perfume-makers for fine fragrances, but the musky scent his two large ‘apples’ gave off left Rarity with a heady feeling, one that got her even friskier. Slowly, Rarity dragged her tongue along his taint, very gently nibbling at the skin of his sack. With experience, the mare had learned those two spots were Mac’s weakness, capable of stimulating his stallionhood to ever greater hardness.
And engorged it was, even further than Rarity’s earlier flirting had gotten Big Mac. She gulped at seeing the full thing, the veins visible even through the fur. Not for the first time, Rarity wondered if she hadn’t gotten ahead of herself. Then she scolded herself. She wanted, needed this.
“Big Mac-u~, you’re so big,” Rarity cooed as she dropped her head to the ground, tongue darting out from below to make a glancing pass at the flare of the penis, before fully engaging. Swirling her tongue around the tip, she licked off the first little drops of precum beginning to hang before gravity had a change to take it, memorising the light flavour. Rarity wanted more, and what Rarity wanted, Rarity got.
Opening her muzzle wide, Rarity took Big Mac’s horsecock into her mouth, one centimetre at a time, just barely able to get her lips past the medial ring before dainty small jaw surrendered to large stallion girth. Closing her mouth, Rarity began to coat the sides of Little Mac in saliva, marking her mate even as her tongue curled around its length, attempting to memorize the bulging veiny contours of his cock. She could feel Big Mac pulse under the steady attention of her tongue, and the unicorn mare could swear he was getting even larger. Good Celestia, what had she gotten herself into tonight?!
For a brief moment, panic overtook Rarity, until it gave way to the heat spreading in her loins. Even as focused as she was on her front cavity, she could feel her rear end getting wet with anticipation. Rubbing her thighs together for the later main event, Rarity brought her attention back to her evening ‘dessert’.
“Mmmm-mph,” Was all she could really get out in a cross between a moan and a comment on the taste of Big Mac’s cock, but it was enough for the larger pony. Grunting, Big Mac lowered his front legs down to lay his head against the floor, no longer certain he had the strength to stay up on all fours.
Rarity didn’t mind, even as the action lowered his stallionhood ever so deeper into her mouth, causing her to almost gag. It placed her nose closer to his testicles, giving her a second good whiff of the combination of sweat, musk and natural maleness that Big Mac exuded. Rarity took to it so much she inhaled a second time, basking in the scent. As addictions went, she didn’t want to be cured of this one.
With deft oral agility, Rarity slowly began to bob up and down on Big Mac’s cock, occasionally daring to shove his flare all the way down to the back of her throat, only to retreat and lather his tip with exquisite licks of her tongue. More precum was dripping out, and Rarity knew she was only moments away from the main course.
Bic Mac’s entire body began to twitch, and Rarity quickly bobbed down, leaving only part of his length in her mouth. Even though it was inevitable at this point, Rarity hastened her coltfriend’s orgasm with several quick licks, before his cock pulsed one last time, and with a grunt of passion Big Mac unleashed a tide of cum into her mouth. The cum came in spurts and gobs, and Rarity’s cheeks inflated like a chipmunk in her attempts to hold the stores of seeds that had been deposited in her mouth.
Sliding off his mouth, Rarity let the stallion juice sit on her tongue even as she breathed through her nose, letting the taste wallow on her tongue. As always, there was the mild taste of fruit, unsurprising really, with the slightest trace of bitterness and saltiness to add flavour. It certainly was no marshmallow flavour, which Macintosh claimed she tasted like when he went down on her.
The moment passed, and Rarity swallowed, not wanting to let such a good thing go to waste. Slowly, the mare crawled back out from underneath Big Mac’s barrel, picking herself up and onto the floor.
“Well well well,” Rarity said, licking her lips clean, certain she had missed a blob or two anyways given the sticky parts of her muzzle, “I may be the Element of Generosity, but it’s certainly good to know that you give so freely of a part of yourself.” She leaned in closer, until she could nuzzle him again if she so desired, “What you say you ‘give of yourself’ yet again, hmm Big Mac?” She punctuated it by waggling her eyebrows.
There it was. Even through all his red fur, she could tell he was blushing. She would have given a hoofbump if there were anypony else to trade hoofbumps with. “Ee-eeyup,” He said, stuttering cutely.
“Oh, woe is me!” Rarity said, raising her hoof to her forehead as she repeated her antics from earlier, and she gave Big Mac a look after he briefly whinnied in frustration before she continued, “But we seem to be having a famine this year. Oh, I do hope somepony out there is so kind as to plant some apple seeds!” Another snort, but this time Rarity knew it to be a laugh, as close as a laugh as Big Mac normally got when he was in one of his stoic moods.
Rarity turned herself around, facing her bed, before lowering her forehooves. Big Mac was a dear gentlestallion, but even beyond all the jokes about his being ‘Big’, he was still big. It was difficult to take him in this position while standing up on all four hooves. Turning her head to face towards Big Mac, Rarity raised her tail up, exposing her marehood in all its full glory just as she gave him her best seductive ‘come hither’ look. She gave her tail a brief flick at his nose, causing him to briefly scrunch his snout. Rarity giggled at how adorable he looked when doing that, before turning her head back around.
Big Macintosh didn’t need any more invitation, as Rarity could suddenly feel his tip poking at her entrance even as he lowered himself down over top of her, his own head curled up in the nape of her neck, hot breath tickling her ear. “Oh!” She gasped in genuine surprise, her lower lips already sensitive and quivering with need for stallion meat to fill her up. “That’s…oh…” Rarity trailed off, the moan all too easily escaping her upper lips, as she realised with a pouty face that Macintosh meant to tease her tonight.
Instead of attempting to enter her right away, the Earth pony was moving his hips to and fro, the length of his horsecock rubbing up against her pussy lips. Rarity panted loudly as her nethers began to burn with a needy heat. Little Mac passing along her clit hood was like a thousand little jolts to her senses, each back and forth a dozen more times potent than anything Rarity could do with her own hoof. “Bi, Big Mac, stooooop teasing me,” Rarity moaned as he continued to grind along the outside of her pussy.
“You sure about that, Rares?” Big Mac growled in a sentence with more than two words, pinning his front hooves against Rarity’s torso even tighter, asserting physical dominance.
“Ye-, er, eeyup,” Rarity said, managing to get the words out through her own heavy breathing, her mind preoccupied with getting that little slice of heaven to stuff her insides.
“That’s my line,” Big Mac said gruffly, and Rarity could imagine his snout scrunching up again, “Only naughty fillies steal my lines, and I think a naughty filly like you needs to be punished.” Briefly, he gave her mane a tug with his hoof.
“Y-yes,” Rarity encouraged him, her jaw clenching as at last she felt Big Mac pressing against her entrance. With almost hesitance, he parted her folds and began to enter. Rarity could feel every centimetre as he went deeper into her depths, and winced for a second as she felt the thick ridge of his medial ring pass through before it, too was accommodated by her pussy. With one last grunt of effort from the farmpony, Rarity let out an “Eep!” as her back hooves were lifted from the floor, leaving her plot hanging in mid-air and at the mercy of Big Macintosh.
Just the way she wanted it.
“You ready for this, Rares?” Macintosh asked, always a little leery about stretching his marefriend out too much.
“I was born ready,” Rarity said, her tail erect and standing up so straight there was no way her invitation could be misinterpreted.
“Good answer,” Big Mac grunted, and he pulled out slightly. Then he rammed straight back in.
Rarity gasped at the sudden sensation as her inner walls contoured and reshaped to fit the stallionhood intent on sowing her innermost sanctuary, waves of pleasure rippling from her tailbone along her spine until it hit her head-on in the face, only for the waves to reverse and travel back through her body and up to her pussy again. Her lower lips tingled with hot pleasure, staging a coup and seizing control of Rarity’s body from her brain, intent on deriving pleasure from the moment as possible.
Then Big Mac withdrew again before forcing himself even deeper, picking up the pace. The sound and feeling of moist fur smacking against moist fur overrode any objections Rarity had to her pussy taking over, as she surrendered sovereignty to her nethers. The colour of her bedsheets, the temperature of her room, even her latest design ideas, all of those thoughts left her head as she blanked out, Rarity’s entire world all focused on the heat down below and the itch deep in her pussy that was being scratched.
Mac continued his piston movements, increasing in speed until he was going full bore, Rarity’s back hooves dangling well above the floor as he fucked her even harder, intent on asserting dominance over the little delicate marshmallow pony that was his. Her lower lips pulsed with contractions, intent on squeezing him dry and using his stallionhood to plug itself up, not letting any drop escape the depths of her love tunnel.
The Red Earth pony could feel the tension gathering up in his thighs, the knot of nerves from his cockhead all the way down to his testicles and even into his crotch all firing like crazy. That brief high he had been waiting for all day was so close, and yet so far. Big Macintosh’s body surged with energy, the wild rivulets of adrenaline willing him further and further. And yet, he needed something more. The oral earlier had been great but left his second load hanging. He needed just one bit more of stimulation to come once again. He licked his lips with nervous want. Rarity would supply him that stimulation, and he knew just what to say to her.
“Do you know why the Apple family has such big reunions, Rares?” Big Mac gruffly asked her, slowing down ever so slightly so that he could talk instead of sucking in sweet oxygen.
“N-Nnnnh, no, why?” Rarity replied, not sure if this was a trick question or not, and thoroughly unable to concentrate on anything more than the heat in her loins as she begged for aching release, attempting to reach it but lacking that last little bit in an unknowing parallel of Mac’s own situation.
“Because we have so many ponies in the family. Perhaps I should rephrase that. We don't stop at two children like so many do, instead Apple couples will have another foal, and another, and another…exactly what I’m gonna do to you,” He whispered breathlessly into her ear.
Rarity’s eyes widened, her thoughts amuck and in horror at his implication. He wouldn’t, would he?
And then suddenly, her head sang, and her thoughts reassembled, and Rarity knew in her heart this was what she truly desired, “Oh, yes, yes, yes,” She said on repeat, the thought of being filled with foal after foal so right that her body couldn’t help but respond in kind, and her pussy squeezed down. But she still needed something more.
“We plant apple seeds in as fertile a spot as we can get,” Macintosh continued, “Then it bears an Apple after jus’ about a year. Then you pamper it and treat it well and you plant some more seed, then you get another Apple after another year.” He wasn’t talking about farming, if he ever had been. “But ya gotta dig deep and deposit that seed, and whisper sweet nothings to it year-round, they’re delicate little creatures dontcha know. Fortunately, I think I have the mother of many, many future Apples right here. You’d love that, wouldn’t you? The pitter-pattering on the floors of several Apple foals?”
Rarity’s ears had curled up at his dirty words, even as her tongue was hanging out of her mouth and a shiver worked its way through her spine both at the raw carnal pleasure awaiting her over that last cliff and the ecstasy his words put her in. “Y-yes!” She panted, the hot itch in her nethers demanding to be soothed, and the thoughts Macintosh was putting in her head were the perfect scratch. “Fill me, Mac-u~, buck me, breed me, fill me up with your foals.” Rarity gasped in mad anticipation, grabbing her bed sheets, holding on for dear life lest she be swept up in the tide.
“Ee-yup!” Big Macintosh grunted, and they came together as one.
Rarity saw stars through a sky of midnight blue. She was floating, she swore, there was no other explanation for this weightlessness. Bliss had swept her off her hooves and left her this way,
Then the moment passed, and Rarity returned to the land of her living, to her bedroom above her shop. Big Mac’s horsecock still filled her, giving her the exquisite feeling of satiation that no fine food could, and her insides felt warm as she was surely painted with his hot cum.
“Hah, hah, hah,” Rarity mustered a weak laugh, her lungs heaving for sweet air with every up-down motion of her chest. Sweat clung to her, and she had to blink out the salty sensation from her eyes. Slowly, she crawled, removing herself from the coupling that had joined Big Macintosh and herself, the movement made easier by his stallionhood already beginning to turn flaccid.
Turning around, Rarity sat on her dock, leaning up against the side of her bed. She looked down and surveyed herself. It was a good thing her fur colour was naturally white. Macintosh had deposited so much seed inside her that some was leaking out, staining her loins. Rarity could take a shower, but…the mare blushed as the words she had said earlier came rushing back to her. Maybe she could wait until tomorrow. Big Macintosh had given so generously to her, after all.
Rarity looked back up and ahead at the stallion of the hour, eyeing his cock. Even as it was slowly shrivelling, Rarity still shivered in trepidation at its girth. Past experience told her Big Mac still had many more apple seeds left in his big red pouch with which to plow her fields. Raising her eyes to look at Mac’s upper head, she swallowed with a nervous giddiness, “So, you big lug, want to go again? I just have the most wonderful bridle that I’ve been dying to try on.”
Big Mac’s giddy grin was contagious to Rarity, “Eeyup.”
Author's Note
Rewatching Filli Vanilli got me hooked on this ship. She gets quite overbearing at times, but Rarity's fussing over Big Mac such as readjusting his tie all hints at a comfortable familiarity, even taking him out all the way to Zecora for a check-up, and there are a few visual bits that stuck out to me such as Rarity looking sideways at Big Mac with one eye closed. I tried to translate those character dynamics here, where Rarity is the talker, but it's definitely not a one-sided relationship, and they're both playful, such as with their pet names.
That said, I attempted to stay away from any 'Big' Mac or 'Little' Mac jokes. It was difficult 
. Then when I went to create a synopsis I ended up using those exact jokes I refrained from making in the story 
I was this close to making a Clifford the Big Red Dog joke 
The working title was 'RariMac', then when I tried to come up with one I tried to make an Apple and Marshmallow pastry joke, and somehow ended up with that instead.
