Big Mac’s O So Sweet Surprise

Chapter 1

The mystery that starts it all...

****

That had been a damn long meeting with Mayor Mare, dragging on to finish almost half an hour after the work day was over. The fact that Big Mac had needed to go during the entire thing hadn’t helped either. He really should have asked for a bathroom break, but it had always seemed like they were just a few minutes from completing the task, before it inevitably dragged on for more than a few minutes more. Nevertheless, all the questions about the farm had been answered, and the answers were good. If things continued like they were, then the farm would be debt free by next harvest.

Big Mac sighed contentedly as he shook off the last drops from his quite sought after stallionhood. He took a few lengths of paper from the side container in the stall and dried and cleaned himself before tossing the paper down and flushing.

He was just about to walk out of the stall when a little knock was heard from his left side. He looked in surprise as a hole suddenly became unplugged, and one second later a little note was pushed through it. Big Mac caught the piece of paper, as he looked down he could see in very fine writing. “Please let me suck your penis, I’m quite good at it.”

Big Mac looked with wide eyes from the note to the hole connecting his stall with the next. Whoever was on the other side wanted to give him a blow job? That was just… wow. He had heard about these kinds of places, but he had never actually had the inclination to look for one. After all, Big Mac had an average of two or three mares dragging him to their homes each week for a little fun sexy time.

Although, it has been almost a week-and-a-half since I last screwed Cheerilee… Big Mac thought while he felt a little twitch from down below. A free blow job is a free blow job.

Still, there was the problem that this was a unisex toilet. It could be either a mare or a stallion on the other side of that wall. And he was no colt cuddlier… okay, he had experimented once, but that had ended rather quickly.

Although that raised the question: how did the occupant of the other stall know he was a stallion? He could just as easily… actually scratch that, it was a lot higher probability that it would have been a mare in this stall going by pure chance. This meant that whoever was on the other side knew who he was.

Could he really do this?

“‘Scuse me,” Big Mac said in his very distinct voice, “but this ain’t some joke, is it? Ya serious about it?”

There was the sound of scribbling from the other side, and then a new note was shoved through. In the same quite beautiful writing stood, “No, no trick. I really want to taste you. And if you’re good, I’m quite flexible in accepting requests as well. Pussy or ass: if you’re a good boy, you can have it all.” There was a little winking eye drawn at the end of the sentence.

So it was a mare, and she was offering more than just a blow job. Big Mac grinned to himself; now it was getting interesting.

“Alright, just a minute,” Big Mac said in his calm voice while he started to fantasise about some of the wilder mares he’d fucked before, massaging his flaccid dick with his hoof.

In a few moments he was nursing quite the semi, and then, with a bit of awkward maneuvering, the big red stallion managed to get most of his cock through the hole in the wall.

A cute little gasp could be heard from the other side, and then the head of his cock was instantly engulfed in a very pleasurable warmth. The mare on the other side started sucking him off while she let her tongue work around the edge of the head of his penis.

Big Mac moaned quite happily, and came to the conclusion that yes, she knew what she was doing.

His cock started to grow rapidly under the pleasurable assault of the mystery mare. She then started bobbing her head up and down while twisting from side to side. The mare’s tongue slithered and expertly massaged the underside of his dick. It was all making Big Mac hiss in pleasure as he could now feel the head of his stallionhood hit the back of the willing mare’s throat.

“Oh, you are good at this,” Big Mac said through clenched teeth. He was going to cum, and soon if this continued. But he didn’t want this to end quickly; it was a far too surreal and wonderful experience not to make it last.

“Can… can you… gah! Hold on for a second?” Big Mac asked to which he felt the mare stop her ministration, but the mystery mare still kept his cock in her mouth massaging it lightly with her tongue while she waited for instructions.

“If yer so into this...could ya turn around?” Big Mac asked hopefully.

The mare’s mouth released his dick with a wet pop, before she dragged her tongue from the base of his cock in a slow long lick ending at the tip. Then it was left alone in the cold air. Big Mac almost started to fear she was denying him, when he finally heard shuffling. Then he felt, what was clearly the nether lips of a female, the soft velvety folds being pressed against his length, dragging sensually along the top of it, before stopping and pressing itself against his flat cock head.

With quite a bit of effort, the mare forced the tip of his quite generous dick into her sopping wet pussy. This unknown pussy, warm and velvety, constricted his throbbing pole with surprising ferocity.

“Oh fuck, you're tight!” Big Mac exclaimed in absolute delight. The only thing he could remember that was even close to being this wonderfully constricting was the times a mare had agreed to take it in the ass. And of the mares that did try, only Cheerilee and Fluttershy had come back asking for more of the same.

Soon the mare had wiggled and brute-forced her way down his long, thick shaft. Big Mac could hear her panting quite loudly. And from how she sounded, she was biting down on something to try to keep herself quiet. Picturing the mare biting down on a ball gag actually made his dick twitch inside of her, and the mystery mare moaned happily.

Being more than ready for it now, Big Mac started to pull out before shoving his dick back into the unknown mare. Because of the wall, he only managed to get maybe two-thirds of his cock inside of her, being generous with his estimation. But still, he was pretty sure he connected with her cervix on every other stroke. Although this wasn’t the first time he had encountered the problem of being too long to fit entirely inside a mare, this was definitely the shallowest pussy he had ever fucked. Then again, with how wonderfully tight said pussy was, he really couldn’t say he minded too much.

After a few minutes of intense thrusting, Big Mac’s dick was suddenly grasped so tightly his eyes almost crossed in pleasure. The mare on the opposite side of the wall squealed through her gag in delighted ecstasy while her pussy quivered in spasmodic bliss, while Mac continued fucking her clenching core.

Big Mac grinned as he realized the mare was orgasming hard, so he gave several extra strong trusts to keep her orgasm going for as long as possible. Even after she came down again, the mare continued moaning happily.

Big Mac had worked up quite a sweat, fucking at such an awkward angle. But still, this was probably some of the best sex he had ever had. The sheer tightness of this mystery mare was glorious, and the fact that he didn’t know who he was riding so vigorously actually added to the thrill.

The two of them keeps on fucking as if this were the only chance the two of them would ever have at intercourse in their life. After twelve minutes more of intense screwing the mare's vagina once again coiled around his dick like a boa constrictor. The sheer pleasure shooting up through Mac’s spine once again skyrocketing while the mare climaxed, Big Mac grunted in euphoria while he forced his big cock as deep into her velvety warm cunt as he possibly could.

The two of them were in elysium, Big Mac fucking her as hard as he possibly could through the hole in the wall, grunting in pleasure though he tried to keep it as quiet as possible, though the chance of being discovered was probably pretty slim — he and Mayor Mare had been the last meeting to finish, and she had actually left ahead of him, saying she had a quick errand before leaving for the day. So Big Macintosh and the mystery mare were most likely the only two ponies in the building right now.

After some more heart throbbing, mind blowing and unrelenting sex, where both participants had most definitely gone all out on their different ends, Big Mac could feel himself coming towards the inevitable conclusion. The mare climaxed for the third time, the wonderful feeling of her pussy clamping down on him like a vice, her velvet walls massaging him like nothing he had ever felt before.

Big Mac let loose a somewhat restrained scream, and buried himself as deep as he could in the mystery mare, clearly feeling the top of his cock grinding against her cervix. As the gates opened, his semen started to flood into the tight pussy which was gripping him, milking him for all he was worth. When Mac finally could feel his squirting spunk starting to subside, he made a few last desperate thrusts trying to extend both of their orgasms as long as possible.

Finally Big Mac fell back against the other wall of the stall sliding down it until he was sitting on the floor panting heavily, with the goofiest smile ever across his muzzle.

From the other side of the stable wall he then suddenly heard the loud thud, indicating that the mare on the other side had most definitely fallen over. There was a pained moan before everything went quiet.

“Miss?” Big Mac asked while he looked at the hole in the wall.

“Miss, is everything okay?” he said a little louder and stood up. But there was no answer.

With a bit of worry, Big Mac exited the stall and stood in front of the next one where the mare would be and knocked on it before speaking loudly. “Y’all okay over there? Talk to me, Miss!”

There was a pained moan before something shifted on the other side. Not wasting any more time, Big Mac grabbed the handle and ripped the locked door open. Then he froze in place.

On the floor in front of him lay a little filly; a little filly he knew quite well. Sweetie Belle, Rarity’s little sister, and one of his kid sister’s best friends. She was rubbing her head a little bit, having apparently fallen down from the toilet when she had slipped on some of his semen that had spilled out of her overstuffed pussy but a moment ago.

Oh dear Celestia, I fucked a filly… I fucked Sweetie Belle… Big Mac thought; his mind felt like it was working in slow motion as he tried to understand just how this had happened.

When Sweetie Belle finally looked up and met Big Mac’s gaze, her eyes turned into pinpricks. They were both frozen in place like that for a while, Big Mac trying to comprehend what he had done, and Sweetie Belle quietly panicking at being discovered.

They just stood there, unable to move, as if they had both looked into the stare of a Cockatrice.

Finally it was Sweetie Belle who broke the spell. “Please, Big Mac… don’t tell any pony… especially Rarity…” Sweetie said in a very pleading voice.

Big Mac’s only response was to sit down rather abruptly, still unable to take his eyes off Sweetie Belle.

“Mac?” the white little filly said as she stood up slowly.

With a worried expression, she started to slowly walk towards the great big stallion, who immediately started scotching backwards until his back hit the wash basin. He looked behind himself only to discover he had nowhere to go. Big Mac looked forward again only to meet the bright green eyes of Sweetie Belle, who was now standing right in front of him.

“Mac, please talk to me,” she said in a worried tone.

Big Mac opened his mouth and closed it again, then tried a few more times before he finally managed to speak just one word. “Why?”

Sweetie Belle’s ears laid back flat at the question. She started dragging one of her front hooves lazily over the other, all the while looking completely adorable. The young filly nonetheless took courage in the fact that Big Mac had not run out the door screaming, and hoped that if she had a chance to explain herself, then maybe this wouldn’t end in disaster after all. “Weeeeeel… it started maybe year and a half ago-”

“You’ve been doin’ this a whole year?!” Big Mac interrupted loudly before clamping his hooves over his mouth, looking from side to side in dread that some pony had heard him.

“What? No!” Sweetie said a little bit annoyed at being cut off, “I’ve only had real sex for… like… six months maybe? Now, don’t interrupt me again, okay?!”

Big Mac blushed and looked a bit sheepish before answering. “Okay…”

“Good, now it actually started almost two years ago,” Sweetie said while tapping a hoof against her chin as she was trying to remember the events all over again. “Anyway, I woke up hearing some funny noises coming from Rarity’s room. I walked over and notched the door open a little bit. Through the crack I could see Thunderlane on top of my sister. His penis was buried all the way in her folds,” the little filly said with an impish smile. “I watched them fuck each other’s brains out for over twenty minutes. They both seemed to enjoy it quite a lot, although Rarity got a little annoyed that he finished inside of her, since she didn’t have a day after potion at hoof.”

“Day after potion!” Big Mac suddenly said in panic.

Sweetie Belle snorted before giving a laugh and smiling up at Big Mac. “Relax you big lug, I’m way too young to get pregnant, you know.”

“Ah… right…” the big red stallion said with a sigh of relief before looking down at the little pink and purple curly maned filly, “Sorry for interrupting…”

“That’s okay, Mac,” Sweetie said while she tapped his thigh with her hoof.

Big Mac looked down at her with surprise. When had she gotten that close again?

“So…” Sweetie said, picking up the story, “I went back to my room and started… experimenting with myself, and boy did that feel good!” She squirmed as if the little filly, remembering the wonderful things she felt that night. “Since that night I couldn’t stop masturbating. I did it every night, more or less. Then came a real breakthrough about a year and a half ago: I found this strange magazine in a hedge, featuring some mares and stallions doing some really crazy stuff with each other. And on the back of the magazine, there was an ad where you could order all sorts of fun stuff to masturbate with. It was quite easy ordering it in Rarity’s name, and then I made sure to be home to intercept the package when it was delivered.”

Big Mac just nodded that he was following the story so far.

“Well, that was how I entertained myself up until six months ago. It had become quite a regular thing for me to find one of those magazines in that same hedge every now and then. And in this one particular issue, there was a story about glory holes… and that’s when it hit me! I could have sex with a real stallion whenever I wanted!” Sweetie Belle said from where she now sat between Big Macintosh’s large thighs, one hoof on each of them, spreading them apart, looking down at his cock which had started to emerge again of its own accord. “And now… I finally have a lover I can be open with, who can satisfy me, without me having to hide who I am.”

“Wait! What?” Big Mac said in shock while his dick emerged a little more as Sweetie Belle had started to playfully massage around his sheath with one hoof while looking up at him with sultry eyes.

“Of course,” Sweetie Belle said with a big smile, “you loved the feeling of having your big cock inside of me. Look into my eyes and say that you didn’t, and I’ll leave right now.”

Big Mac looked down at her with wide eyes, sweat running down his forehead. He had to do this; it was for her own good and his. All he had to do was say he didn’t like it.

“Best mare I ever had…” Big Mac looked perplexed; that wasn’t what he had intended to say at all.

Then he gasped and looked down, finding Sweetie Belle with his cock buried in her mouth, once again giving his semi-erect penis a blow job. His head slammed back against the wash basin, groaning loudly in pleasure as he looked up at the ceiling.

No! Big Mac thought desperately, I… I need to stop her… this is… so wrong… This… this feels so fucking good!

He could feel his resistance melting away like a snowball being tossed into a bubbling volcano. He looked down and found that his right hoof had grabbed the back of Sweetie Belle’s head pressing her down onto his throbbing shaft. And he could feel the smile on her lips, all the while her tongue was playing with the veins criss-crossing his massive cock, letting her feel the pulsing of his heartbeat.

Big Mac groaned again, while guiltily wishing her throat was big enough to take him down his entire length, but that would not be happening for quite a while.

Wait a minute? Was he really going to do this? Continue to have sex with this underage filly?

His head slammed back again as he felt Sweetie Belle’s tongue make a particularly pleasurable circle around the head of his dick.

Oh fuck yes! Mac thought in glee. He was going to screw this filly for as long as she would have him!

His mind made up, Big Macintosh released his grip on her head, allowing Sweetie Belle to pop his cock out of her mouth, only for her to give his member along sensual lick from the base to the tip. She then started kissing it lovingly down each side.

“So…” Sweetie Belle said between kisses along his stallionhood, “are you ready for another round?”

Big Macintosh looked down at this wonderful little filly, his filly, his fillyfriend. And for the first time since this conversation started, he gave a genuine smile and answered, “eeyup.”

Sweetie Belle immediately started crawling up on his stomach, where Big Mac helped her to realign herself with his cock. Then as they looked into each other’s eyes, Sweetie started to sink down on his stallionhood while giving a long sensual moan.

Macintosh hissed through his teeth while he felt his bulky length once again being enveloped in the most fantastic pussy he had ever had the pleasure of entering. Her moist, burning hot velvety walls, slowly but surely stretching out to receive his iron hard rod.

Sweetie meanwhile was moaning and whimpering at the wonderful feeling of being stretched almost beyond her capacity. The wonderful feeling of slight pain overridden by immeasurable pleasure coursing through her, making her want to take Big Macintosh’s throbbing cock even deeper inside of her core.

Then the top of Mac’s dick finally collided with Sweetie Belle’s cervix making her gasp before she bit onto her lower lip to keep from crying out.

Feeling that he’d reached the end of Sweetie’s pussy, Big Mac stopped and looked down to see that he had once again only buried a little over two thirds of his entire length inside of his lover.

The two of them stared into each other’s eyes, both just feeling the wonder in the fact that they were together like this, the absolute pleasure of being connected so intimately with each other.

“Big Mac…” Sweetie Belle breathed huskily.

“Yes Sweetie…” Big Mac answered just as softly.

“Please…” Sweetie began, “fuck me, mount me, rut me, penetrate me, ram me, plough me, pound me, buck me!” The little filly said it with desperation in her voice before she once again got a hold of herself. “But most importantly… make love to me…”

Big Mac just looked down at Sweetie Belle with acceptance and affection in his eyes before answering, “eeyup.”

And with that Big Mac easily picked Sweetie up in his forelegs, before turning her around with his cock still buried inside of her. Sweetie Belle moaned, feeling her back now resting against Big Macintosh’s muscular chest and stomach. The big red stallion hooked her rear legs with his front hooves and proceeded to lift her up, until only the tip of his member was still inside of her. Then slowly he let gravity impale her on his shaft again.

Sweetie couldn’t help it; she gave a little outcry in pleasure. Feeling her stallion’s throbbing length once again entering her pink quivering and very moist depth. Her back instinctively arched off Big Mac’s stomach while she cried out again. He hadn’t even begun to really fuck her, and Sweetie Belle was already on the verge of her next orgasm. The feeling of being spread so incredibly wide overwhelming her. That good pain, like stretching out muscles she didn’t really know she had.

Sweetie Belle started squirming and grunting as Big Mac increased the pace of their intercourse, her excess pussy fluids starting to run in rivulets down Macintosh’s now gleaming cock. Every time his dick left her, she yearned for its return, and every time it hit her cervix, her vagina clamped down on Big Mac’s wonderful cock as if her pussy was trying desperately to suck the shaft even deeper inside of her privates. Very soon she cried out fully as an orgasm rocked through her young body.

Big Macintosh meanwhile was panting heavily, having grabbed hold of Sweetie Belle quite roughly, pinning her legs against her own body while lifting her up, and then shoving her down on his cock again, going harder and faster. He buried his face in her mane, breathing in the scent of the vanilla shampoo she used for washing. Then he started kissing down the side of her cheeks, continuing down her neck and out on her shoulder.

That was enough. Sweetie Belle cried out again as the orgasm gripped her body, her vagina clamping down on Big Mac’s cock so hard it almost locked in place. But with his immense strength, Big Macintosh managed to continue fucking Sweetie Belle even through the most intense orgasm she had ever had.

When she finally came down, Sweetie Belle could feel how Big Macintosh’s dick was throbbing inside of her. She understood that he was getting close to ejaculating, but she wasn’t done yet: she wanted more, and she wanted to give more.

“Mac… Mac hold-up…” Sweetie Belle managed to squeak out.

“What!” Big Mac asked a bit loudly. He was still fucking her, but his pace slowed down enough for her to speak now.

“I… I have something else I want you to do… please…” Sweetie Belle said breathlessly.

Reluctantly Big Macintosh had now stopped, although his shaft was still buried as deep as it could go. He gulped down a few lungs full of air and spoke. “What is it?”

“There’s… there’s still one place you haven’t tried,” Sweetie Belle said while blushing fiercely.

The words processed through Big Mac’s brain, and then his eyes went wide with understanding. “What?! No, you’re...that ain’t gonna work,” Big Mac said but nonetheless smiled down at Sweetie Belle. “Appreciate the thought, though.”

“And why not?” she said with a bit of annoyance. “You think I haven’t played with my own ass? I've got quite a selection of butt plugs, and I’ve tried most of them.”

“Still…” Big Mac looked down at Sweetie Belle’s petite body. “Ah’m not the easiest stallion to fit in tight spots.”

Sweetie Belle rolled her eyes. “Yeah, you think I didn’t notice?” Then Sweetie tilted her head up, kissing Big Mac’s chin lovingly. “I know it might not work, but I want you to try. I want to give you all of me. Besides I do have something that might help.”

With that she leaned forward and landed on the floor in front of Big Mac, although his dick was still connected to her pussy. With a final little tug, she freed herself from his impalement, which made both of them give a reluctant little sigh. Both their ears perked up at this, causing Big Mac to smile and Sweetie Belle to giggle.

With a pep in her step, Sweetie went into the stall she had been occupying earlier, retrieving her saddlebags. She scooped up the tennis ball she had used as a gag earlier before she brought the bag out and opened it. As Sweetie Belle put the still wet tennis ball back in her bag, Mac got an opportunity to see inside it. He could see papers, quills and a bottle of ink. Sweetie Belle reached into the saddlebags and withdrew a different bottle. It was square, and when Sweetie Belle presented it to Big Mac he almost laughed out loud.

“Extra virgin olive oil?” he said with a crooked smile. “Ya really want to try this?”

“Yeah, I do. It wouldn’t be my first time either, Mac… But you’ll definitely be the biggest I have ever tried to take in my ass,” Sweetie Belle said and somehow managed an innocent smile.

“Okay...” he said with a nod. “We’ll try.”

He then uncorked the bottle, and started pouring the oil along the top of his cock. Sweetie immediately stepped forward and started stroking his appendage lovingly, spreading the slick substance all over his massive shaft.

Sweetie Belle was looking at Big Mac’s dick like she was in a trance while she worked it over, causing Mac to smirk down at her.

“Second thoughts, Sweetie?” he asked.

“What?” the little filly said while she looked up at him. “No! It’s just… it’s so… so… majestic!” Sweetie Belle said with a strained smile.

“Ah think ya mean ‘big’,” Macintosh said with a teasing voice.

“Oh, shut up!” Sweetie Belle answered in a good-natured jab. “Now would you be so kind and add some oil at this end too?”

With that Sweetie turned around and presented her rear to him, making sure her tail was as far off to the side as she could possibly keep it.

Big Mac nodded and let a bit of oil drizzle down on her ass cheeks and sphincter. Putting the bottle down, he started massaging the oil into her ass, paying close attention to her rectal opening, using the tip of his hoof to massage it, and making it relax as much as possible.

Moaning pleasantly, Sweetie Belle’s front hooves gave way and she slumped down to the floor while Big Macintosh continued to tenderly stretch her asshole. “Wow… that actually feels really good, ” Sweetie Belle commented.

“I’m glad you like it so far,” Big Mac answered and started using his second hoof tip to stretch her sphincter even more open.

“Mmmm… I can’t wait to feel you inside of me again, Big Mac,” Sweetie purred teasingly.

“We’ll see,” Mac answered, still not sure that was going to work.

Finally certain he had done all he could, Big Mac stood up, only to realize a small problem. Namely how little Sweetie Belle was in comparison to him. Even if he was standing on top of her, as he did when he normally fucked a mare, their size difference would most definitely complicate things.

“Hmmm…” Big Mac hummed while he looked around. Then he saw the solution, if he put Sweetie Belle on the wash basin, he would be able to fuck her quite happily from behind.

With a surprised yelp, Sweetie Belle was picked up and then situated between the two sinks; where there was a perfect flat area for her to lie down on. This also gave the added bonus of the two of them being able to watch each other in the mirror as they fucked. Big Mac gently pushed Sweetie Belle down so she lay flat with her hooves underneath her, her ass just sticking out over the edge of the wash basin.

He then proceeded to stand up above her, towering over her like a Titan, making Sweetie Belle feel just how utterly under his power she was right then. And it kind of thrilled her; after all, she felt completely safe with Big Macintosh. He would most likely abort this way before she would ever ask him to do so.

“Ya ready?” Big Mac asked Sweetie Belle in the mirror.

As Sweetie Belle looked back at him, she let out a little moan of anticipation, “oh yes, and please do give this some real effort. I’m quite flexible you know.”

“Once Ah know it’ll fit at all,” Big Mac said and brought the flat tip of his cock to her puckered little anus.

Both Big Mac and Sweetie Belle took a deep breath in anticipation. And then he pushed forward, but instead of entering her, he only made Sweetie Belle glide across the counter top. He quickly brought a hoof to her shoulder, dragging her back to her original position and then pinning her in place with both of his powerful front hooves.

Once again feeling the enormous strength of the stallion who was about to mount her, made Sweetie Belle shiver in anticipation. The contact between the two of them where he gripped her shoulders seemed to heat up as if electricity was shooting between the two lovers.

With Sweetie Belle now firmly secured in place, Big Macintosh started pushing forward again, rocking his hips, and massaging her reluctant anal sphincter with his cock.

“Harder,” Sweetie Belle ordered him from below.

As ordered, Big Mac leaned even further forward, increasing the pressure on her asshole. Sweetie Belle grunted and squeaked below him, but she wasn’t telling him to stop. If anything, Big Mac could swear he felt her press back against him.

“Harder, Big Mac! I know you’re holding back!” Sweetie more or less yelled up at him.

With that, Macintosh gave a loud snort, clenched his teeth together, and really laid into Sweetie Belle. A pained little squeak escaped her, and he was just about to pull back and say this wouldn’t work, when the first inch of his shaft was suddenly and quite brutally forced into her back door.

Sweetie gave a cry of pain, and desperately clung onto Mac’s front hooves. Big Macintosh looked down in wide-eyed shock at what had just happened, and started to pull back out. Only for Sweetie Belle to quickly reach up with one of her front hooves and grab onto his pelvis, keeping him in place.

“No!” she forced out through clenched teeth, “stay where you are!”

“But-”

“Yes, butt!” Sweetie hissed. “As in, the butt you’re going to fuck!”

“Sweetie! This is… we oughta stop! I’m too big for ya!” Macintosh protested.

“Naha… it’s… it’s already starting to hurt less,” Sweetie Belle panted. It was a lie, but Big Mac didn’t need to know that. “Just give me a little time to… adjust.”

“Okay…” Mac said reluctantly.

Although he had to admit, if Sweetie Belle’s little pussy felt spectacular, then her ass was nothing short of Elysium made flesh! Only that little inch he had managed to force into her was pulsating with a pleasure he had never experienced before.

“Okay,” Sweetie Belle suddenly said, her voice still sounding a bit squeaky, “keep going…”

Now having a small indication of what was awaiting him inside of Sweetie Belle’s tight little plot, he was feeling a lot more enthusiastic about the prospect of pushing in deeper. With more eagerness, Big Mac once again used his considerable strength to force his way further into the soft and supple flesh of Sweetie Belle’s ass.

Sweetie Belle meanwhile was biting her lower lip to the point that she was almost bleeding, and still she could not keep from grunting and moaning in pain. Even though she could feel the slickness of the lubrication working its magic, she was in quite a lot of discomfort. The enormous difficulty Big Mac had at pushing forward into her should have been an indication to stop. But Sweetie steeled herself and took it; she could after all feel her reluctant ass slowly but surely give way to Big Mac’s well-oiled shaft.

As more and more of that wonderfully pulsing stallionhood penetrated her spasming and clenching rectum, it screamed in protest. Then suddenly, almost a quarter of Big Mac’s shaft abruptly sunk into her ass in one fluid motion, several sphincters in her colon having given up their attempts at resisting the intrusion and instead conformed to the invasion in Sweetie’s asshole.

“Wow!” Big Mac exclaimed, almost dizzy from the sheer pleasure coursing up his pulsing stallionhood, which was now buried quite a respectable way inside Sweetie Belle’s tight little back entrance. “Oh, Luna’s teats! Ya feel...ngh, fuckin’ fantastic, Sweetie Belle!” Big Mac proclaimed ecstatically while he started rocking his hips back and forth, slowly moving his massive cock inside of the tight and mind numbingly pleasurable tunnel of lewd wetness and all-consuming warmth.

Finally Sweetie Belle managed a weak grin. She was still in pain, but it was nowhere near as bad as it had been just a moment ago. She took a large shuddering breath, realizing she had been holding it for quite a long time. Her burning lungs gulped down the sweet cool air, making her discomfort subside even more.

Big Mac could feel the petite little filly beneath him finally starting to grow less tense, even as he shifted his considerable girth back and forth inside of her. Still he had to use a substantial amount of strength to move his cock even a little bit inside Sweetie Belle’s asshole. She was so tight; so gloriously, wonderfully, euphorically tight.

As Big Mac was washed away in a sea of ecstasy, Sweetie Belle lay beneath him, whimpering as each powerful thrust into her sent a new spike of pain through her body. And still she did not cry out for him to stop, even as she felt how he began to fuck her harder and more insistent with each passing thrust.

Big Mac meanwhile couldn’t believe it; it was just getting better and better. There was no question any more, this was the best sex he had ever had. And it was with Sweetie Belle, a little filly that he had thought to be so innocent and pure.

Then his eyes shot wide open as another plateau of pleasure was reached. His medial ring was popping in and out of her tight little overstretched sphincter with every unyielding thrust. Big Mac looked down in wonder at the spectacle, but what he saw below wasn’t the happy little filly he had fucked earlier. She was biting her lip to keep quiet, her face was scrunched up in what could only be agony, and there was a small tear running down her cheek.

Big Mac froze, half his impressive length buried inside of Sweetie’s quivering asshole. Oh by Celestia! Big Mac thought guiltily as he realized what he was doing. He had lost himself in his own euphoric pleasure; he had never lost control like this before. Usually he was a very tentative stallion to his mares; trying to make sure they felt as much pleasure as he did. And for the last, Big Mac didn’t know how many minutes; he had been railroading Sweetie Belle in the ass, completely lost in his own desire. Quite frankly he had been brutally pushing further and further into the little white filly without mercy.

He took a deep breath and looked down at Sweetie Belle. She lay beneath him, breathing heavily and clutching his front hooves for support while she waited for the next thrust into her heavenly tight asshole. No, it doesn’t have to be like this. I can make this a lot more pleasurable for her, and still get what I want for myself, Big Mac thought, and with his mind made up, he carefully rolled Sweetie onto her back, locking eyes with a very surprised Sweetie Belle.

“Big Mac?” the little petite filly asked in worry, still a bit out of breath. Had she done something wrong? Didn’t he like fucking her anymore? She had been as quiet as possible, and she had let him do anything he wanted to her. Just like the magazines told her to do if she wanted to keep her stallion happy.

“Ah’m stayin’,” Big Mac assured. “Don’t worry.” Big Mac said and leaned down, he had to bend his back rather awkwardly since his cock was still half buried in her ass hole. But he still managed to capture Sweetie Belle’s lips in a tender and loving kiss. He poked her lips with his tongue and she let him enter, their wet muscles coming together for but a moment before Big Mac much bigger tongue overpowered hers completely. His tongue reaching deep into Sweetie Belle’s mouth, exploring and ravaging her, sending waves of pleasure into her brain.

He let go with his right hoof and slowly trailed it down her side until it situated itself between Sweetie Belle’s widely spread legs. Softly and tenderly he started stroking her velvet nether lips with the tip of his hoof.

Sweetie Belle couldn’t help but arch her back a little bit at the wonderful contact, the delightful pleasure it sent as he caressed her vaginal entrance so tenderly, Big Mac’s hoof moving up and down the length of her slit several times before he settled over her swollen clitoris and started massaging it lovingly. She had been moaning happily into Big Macintosh’s mouth, but when he started massaging her clit, it took barely a minute before she broke the kiss, crying out in pleasure while the orgasm rocked through her trembling body, Sweetie’s back rising off the wash basin as she tried to force Big Mac’s hoof to grind against her clitoris harder.

As Big Mac gently brought Sweetie Belle down from her orgasmic high, softly massaging her pussy and clitoris, the green eyes of Macintosh and Sweetie Belle met each other, each shining brightly with desire and love.

“Sweetie… Yer beautiful,” Big Mac said dreamily, making the little filly beneath him blush at her stallion’s praise. “An’ ya feel so good...I can’t describe ya. Ah never had a mare that feels...even half as wonderful as you. Even yer big sis...doesn't come close,” he continued with a broad smile.

"Really?" Sweetie Belle whispers while she smiled back up at him, and he knew it was time. With a node, Big Mac brought his hoof back to her shoulder grasping it firmly but gently. Then he pulled out a bit from her asshole before pushing in again, slowly but surely starting to once again fuck Sweetie Belle in her anus, although being much more mindful of her this time around.

Sweetie Belle immediately moaned, but not just in pain this time. There was still a lot of strain put on her from his considerable girth, but besides that and the little spike of ache that every other thrust caused her, it was nowhere near as bad as it had been. And she could most definitely feel an ember of pleasure from Big Mac’s wonderful stallionhood getting pushed in and out of her tight little anal sphincter.

Taking a leaf out of Big Mac’s book, Sweetie Belle brought her hooves down to her marehood. She used one hoof to stroke her velvety pussy lips, while the other massaged her clitoris in firm confident strokes.

Sweetie couldn’t help but moan loudly now, the pleasure coursing through her from her own masturbation, plus the equal measures of pain and pleasure coming from Big Mac fucking her in her ass. It all somehow mingled into an altogether new and wonderful feeling inside of her burning core.

Big Mac looked down at the little filly while he continued to fuck her gently but firmly, the expression of pure bliss spread across her face was one of the most beautiful things he’d ever seen. He leaned down again, even if it made his thrusting a bit harder to accomplish, and captured her lips in another wet and slobbering make out session, both of them moaning into each other’s mouths, as they slowly rose together on an endless tidal wave of pleasure.

The minutes rolled on as Macintosh continued to penetrate Sweetie Belle’s wonderful little backdoor. He had his head resting against the mirror now, sweat dripping off his body, his eyes closed to be able to enjoy every single thrust into his wonderful little filly friend.

Suddenly he heard a faint slap. His eyes shot wide open as he looked down in astonishment, only to see his next thrust bearing his entire stallionhood inside the petite white unicorn. Sweetie Belle’s wonderful ass had swallowed his entire, quite considerably sized cock, all the way to the hilt.

Mac and Sweetie once again locked eyes, both as surprised as the other at this development. After a few more thrusts, which were each accompanied by the wet slap of Big Mac’s hips meeting Sweetie Belle’s plot, they both smiled at each other.

“Big Mac…” Sweetie Belle panted, “you are inside of me… completely inside of me… it feels so good… your cock feels so good… I love you so much, Big Mac… please take me as your special somepony!”

“Oh Sweetie…” Big Mac replied, interrupted only by the slapping sounds of his thighs and his own strained breath, “Yer...yer wonderful, an’ beautiful…no filly ever felt…nice as you do. Of course yer my special somepony!” he finished, seeing how he liked the feel of saying it.

“Gaaah!” Big Mac then roared as his semen started to pump into Sweetie Belle’s tight ass. He desperately and sporadically continued to thrust into her while he came, trying to prolong his pleasurable apex as long as he cud. With a final thrust, he hilted himself inside Sweetie Belle and stayed there, barely supporting himself on shuddering back legs.

Finally they gave way, and he fell back on his plot, his cock popping out of Sweetie’s ass with a wet slurp, followed by his semen gushing out of the still widely gaping hole. He looked at the lewd display in both bewilderment that he had actually fit inside her so completely, and no small amount of pride that Sweetie Belle had been able to take him like she had.

Sweetie lay panting on the wash basin, her rear leg twitching sporadically after the absolutely mind-blowing fucking she had just received.

Big Mac rose up again on shaky legs, before moving over to Sweetie Belle. She was barely able to lift her head to smile at him, but smile she did. With a mischievous grin Big Mac lowered himself towards Sweetie’s crotch once more, using one hoof to spread her legs wide again.

Sweetie Belle looked up in surprise, not knowing what was happening, and then gasped out as Big Mac’s entire mouth encased her nether lips in a deep lewd kiss. “Ahhh!” Sweetie cried out in pure pleasure as the great big stallion pushed his tongue deep into her pussy. His tongue wiggling inside her quivering vagina, in dexterous displays no cock could ever hope to imitate. He could still taste himself inside her, but Big Mac didn’t care. Sweetie Belle had not received an orgasm at the same time as he did while fucking her in the ass, so levelling the playing field was the least he could do for her wonderful gift to him.

“Oh! Yes, yes, yes!” Sweetie cried, writhing underneath his administration. “Right there! Right there! Oh, please yes! Oh! Oooooo! Yeeeees!”

Big Mac continued his lewd slurping as he completely ate Sweetie Belle’s privates out, her eyes having rolled into the back of her head, while she gasped, submerged in pure ecstasy.

Big Mac felt her filly juices running down his chin, while he now repeatedly licked along her pink slitted opening, before he once again covered her entire honeypot with his mouth, massaging her insides with his tongue, and using his upper lip to sensually stroke and massage her wet clitoris.

Sweetie Belle screamed to high heavens as the most intense orgasm she had ever felt rocked through her, her head whipping from side to side while she was babbled gibberish about fucking, sucking and things she should have no idea what they were at her tender age.

As the little filly finally came down from her orgasm, she could feel how Big Mac was kissing her tenderly along her inner thighs, giving her still quivering pussy lips a tender lick every time he changed from one thigh to her other. She lay gasping where she was, while she continued receiving tender love from her wonderful stallion. She was completely and utterly sexually satisfied, in a way she had not even been close to before in her life. Finally she gathered enough energy to lift her head and watch her red big stallion tenderly kiss her right inner thigh while he looked at her with a wide smile.

“So,” Big Mac asked in between kisses, “did ya enjoy me ruttin’ ya?”

“Big Mac,” Sweetie Belle said as she gave a loud satisfied sigh, “it was a pure delight giving you a blow job. Every time I felt your cock inside of my pussy, my whole body was singing in pleasure. Even the way you were fucking me in the ass felt good at the end…” Her eyes went wide with delight. “And, oh my gosh! Do you ever know how to eat my cunt out!”

Big Mac gave a little laugh at Sweetie Belle’s sudden use of a rather crude word. “Glad ya liked it, Sweetie, ‘cause no mare ever felt nice as you. Do ya...ya really think we’ll do this more?”

“Are you kidding?” Sweetie Belle asked in bewilderment. “You are the one I’ve always wanted to sleep with, every time I followed a stallion into the stalls. You were the one I’ve always dream about. You’re the one I wanted to get ready for, and you are the one I want to feel inside me again and again and again.”

They both smiled at each other. This was the beginning of a beautiful relationship: Big Mac could just feel it. But they’d have to keep it quiet for a long time still, or things would not turn out well. If the rest of Ponyville found out that they had become lovers, they would most likely throw him to the Timberwolves, no matter how much they try to explain things.

“So… what do we do now?” Sweetie Belle asked timidly.

“Well...gettin’ kinda late, so how ‘bout we wash up before gettin’ you home? Yer big sis is gonna worry before long,” Big Mac answered.

“I know, I know. And I brought shampoo and stuff for us to clean up." She shuffled a hoof guiltily on the ground. "I might have planned this out… having done this a few times already. But what are WE gonna do now? Are we really together? When can we fuck again? How do we make sure nopony else finds out and breaks us up because 'it's not proper for me to have a coltfriend yet'?" she finished, in a faint mockery of Rarity's voice.

Big Mac hummed in thought while he picked up Sweetie Belle and placed her on his broad back, together with her saddlebag. He continued to think while he pushed the door to the bathroom open, carefully looking out at the dark hallway outside. Yes, there is definitely no pony left beside us in the building.

“Well…” Big Mac began as he made his way down towards the shower Sweetie had indicated, “we got a shed way on the east edge of Sweet Apple Acres. Usually just keep tools there, some hay...bet Ah could do some work on it when Ah got the time.” He looked back over his shoulder grinning at Sweetie Belle. “Ya like that idea, Sweetie? A li’l love nest, sneakin’ over there and ruttin’ loud as we like, as long as we like? Nopony’d ever bother us that far out.”

“Really?!” Sweetie Belle exclaimed excitedly.

“Eeyup!” Big Mac said as he opened the door into the shower. “Anything we wanna do there, we can. Bring yer magazines too if ya want someplace to hide ‘em...or maybe use ‘em for ideas. Got a few ideas of my own on what to do with you next.”

“Like what?” Sweetie Belle asked questioning, a little grin across her face.

“Oh, no you don’t, Ah won’t spoil the surprise,” Big Mac said with mock sternness while he placed Sweetie Belle in the shower.

“Oh, come on!” Sweetie tried in a pleading tone. “You can tell me!”

“Nnnnope. Yer gonna have to wait an’ see, my naughty li’l filly,” Big Mac said while he turned on the water, taking a few seconds to adjust the temperature before grinning down at Sweetie. “But since ya ask when we can fuck again…”

Big Mac moved his left front leg, showing Sweetie Belle that his dick was once again fully stiff and ready.

“Wow! You can go again? This will be the fourth time!” Sweetie Belle said excitedly while she could feel her pussy quickly getting wet again, and not just because she was standing in the shower.

“When ya got two or three mares a night lookin’ fer a helping hoof, ya get good at keepin’ yer stamina up. And that ain’t even half as wild as you girls can get during estrus,” Big Mac said with no small amount of pride. “Can’t say I’ll go again after this, so what does Sweetie Belle want this time?”

Sweetie Belle squirmed a little bit as she thought about what she wanted, looking up at Big Mac a bit uncertain. “Would…” Sweetie began shyly. “Would it be okay if I gave you a blow job again? I’m still a bit sore in my butt and pussy.”

Big Mac only sat down and smiled, nodding approvingly to Sweetie Belle who immediately shone up at not being reprimanded for not giving Big Mac what she thought he wanted. So then with the enthusiasm only a filly could produce, Sweetie Belle leapt forward and closed her mouth around Big Mac’s generous stallionhood.

The big red stallion sighed contentedly as the little white filly started her masterful ministration of oral pleasure. Oh, she is so good at this… Big Mac thought with a grunt as he felt his cock hit the back of Sweetie’s throat, her wonderful little tongue slithering all over his dick, as if it had no higher purpose than giving him pleasure, curling around his shaft as she twisted her head from side to side, finding all the places that just made Big Mac want to cry for joy.

It was probably a good thing he had said this would be the last time for them tonight, or else he was pretty certain they would not stop until the Mayor’s office opened again tomorrow… or wait a minute, it’s Friday. They wouldn’t stop until it was Monday morning at eight o’clo-

Oh, FUCK! She is good!

Chapter 2 Second Fuck is the Sweetest

Big Mac’s O So Sweet Surprise

Chapter 2

Second Fuck is the Sweetest

****

Still the same glorious night…

The two newly christened lovers walked back through the darkening streets of Ponyville, Sweetie Belle riding on Big Mac’s back, snuggling into his thick yellow mane. The shower had taken, well, a lot longer than planned, as neither of the two had been able to fully resist the urge to pleasure the other. Unable to resist opportunities to suck, nibble, or slurp at each other when they were in such easy reach, it was most likely the longest shower Big Mac had taken in his entire life, and definitely the most pleasurable one. Now the streets were more or less empty as they sauntered along towards Rarity’s boutique.

“We're still in public, Sweetie," Big Mac said, chuckling despite the admonishment. "We oughta keep a lid on it.”

“I don’t want to!” Sweetie complained in a squeaky voice. “I want to feel you inside of me again soon, Macintosh… when can we be together again?”

Macintosh hummed in thought. “How 'bout I convince Apple Bloom to have a sleepover next weekend? Should be done with our li'l hideout by then, an' we can do whatever we want out there.”

“A whole week?” Sweetie said desperately. “But I want to have sex tomorrow, and the day after that and the next one as well!”

“Alright, alright. We can meet up...somewhere, Ah guess. Can't do it every day though. We gotta keep this a secret.” Big Mac said and softly nuzzled Sweetie Belle, who still pouted a little bit.

“Fiiiiiiine!” Sweetie Belle nonetheless said, just as they stepped up to Rarity’s boutique.

With a firm hoof, Big Macintosh knocked on the door, and it didn’t take long for a very annoyed looking Rarity to open the door.

“Oh, Big Macintosh?" Rarity's eyes widened in realization. "Terribly sorry, darling, but… is this very important? The girls and I were about to go out and look for Sweetie Belle. She disappeared on me when I left some paperwork at the Mayor's office. Perhaps I'm anxious over nothing, but I haven't seen her since and...well, I'm a little worried.”

“Well funny thing…” Big Mac said with a smirk, “I did run into this cute little filly a little while ago.”

With that Big Mac turned so Sweetie Belle became visible to Rarity, who immediately fixed a glare on her little sister.

“Hehe… hi sis…” Sweetie said innocently while waving at her fuming sister.

“Don’t you, ‘hi sis’ me, young lady!” Rarity said sternly, “Where have you been?! I was getting dreadfully worried about you!”

“Oh, so now you’re worried about me?” Sweetie said and looked a little bit affronted. “It’s not like I have been trying to talk to you all day, is it? And then when I finally get tired and walk away, then all of a sudden you want me with you straight away?!”

“What?” Rarity said in surprise at the reprimand, pinning her ears back.

“You didn’t even notice, did you?” Sweetie Belle asked in annoyance.

“What are you talking about? I had a lot to do today, an—” Rarity cut herself off suddenly, narrowing her eyes at Sweetie. “That is beside the point right now!" the white mare shot back, realizing she'd been put on the defensive.

“No, it isn’t!” Sweetie Belle countered shrilly. “I had something I needed to talk to you about all day, but you wouldn’t give me a second!” the filly said and crossed her hooves. “So I finally had enough and walked away only to bump into Big Mac. And you know what he did?” Sweetie said now looking pointedly back at her sister. “He took all the time in the world to listen to me, and now everything is solved and I am the happiest filly in the world! So there!” Sweetie Belle ended her rant with a sharp nod; before giving Big Macintosh’s broad neck a giant hug from where she sat. “He’s the best stallion ever!”

Rarity looked crestfallen at the accusation against her. She did remember that Sweetie Belle had tried to get her attention a few times during the day, but that was completely normal. It’s what she did every day.

Oh dear… it’s what she does every day. And every day, I almost always turn her away, Rarity thought in guilt, before looking up at her little sister uncertainly.

“Well, I’m sorry, dear. I didn't realize it was so very important, but if you still need to talk, you have my undivided attention.” Rarity said with a careful smile.

“Nah… Big Mac and I already talked about it, and he was really helpful with the way he took care of me,” Sweetie Belle said and again nuzzled into Big Mac’s neck.

“Now, now, Sweetie.” Big Mac said in his deep calm voice. “You an' I had a very nice evenin'. No call fer ruffling manes like that, y'hear? Ah bet Rarity woulda dropped everything for ya if she could've.”

“Well, yes, of course I would,” Rarity said emphatically before looking over at Macintosh with a thankful smile for coming to her defense. “And I’m so very happy you bumped into Macintosh of all ponies. Celestia knows you could have run into some shady characters otherwise.”

“I know not to walk into a dark alley with a stranger, Rarity,” Sweetie Belle said, looking at her big sister as if she were a bit daft.

“Well…” Rarity said before coughing twice, getting a rather visible blush and looking over towards Big Macintosh. “I am very happy it was you she ran into, and that you could help her with her little problem. Now, Sweetie, please come inside. It's well past your bedtime.”

“Do I have to? It’s Saturday tomorrow,” Sweetie Belle said in a whine.

“Yes you do. However there should still be some food left...oh dear." Ears pinned back guiltily as she remembered her guests, Rarity turned around and called into the boutique, "Ahem, girls? Sweetie Belle is back and she's alright! We don't need to go searching for her after all!”

It didn’t take more than a few minutes before five very recognizable ponies stood in front of Big Mac and Sweetie Belle.

“Well howdy brother,” Applejack said when she saw Big Mac, “what brings you around here?”

“Oh, I was just dropping off somepony I ran into,” Big Mac said as he lowered Sweetie Belle to the floor.

“Thank goodness…” the meek voice of Fluttershy said. “We were all starting to get so worried about you.”

“Yeah, sorry about that,” Sweetie said, scuffing one of her hooves against the floor, “but I was with Big Mac and he took really good care of me.”

All the mares smiled up at Big Macintosh who just gave a little nod of his own head in response.

“All’s well that ends well,” Twilight said happily as she walked out through the door. “I’ll see you girls tomorrow then!”

With that, the purple Alicorn disappeared in a teleportation flash.

“Why did she bother to go out the door?” Rainbow Dash said from where she was hovering. “Oh well, see you!” And with that the prismatic-maned sky-blue Pegasus disappeared out through the window, leaving only her signature rainbow trail behind.

“I could have sworn that window was closed just a moment ago, ” Rarity said in annoyance as she walked over to close it again.

“Ah think they got the right idea. Let's head home, everypony,” AJ stated.

Then with a few goodbyes, Pinkie, Fluttershy, Applejack, and Big Macintosh were heading off to their respective homes.

A minute or so of walking, Applejack fell just enough behind to notice something about Mac's stride, and her eyes narrowed suspiciously. "Wait a dang minute, Mac. Ah know that strut," she began, a positively evil smirk growing as she accused him slowly: "You just rutted somepony today!”

Big Mac just halted and looked at his sister with his usual calm expression before answering. “Eeyup.”

“I knew it! So who was it?” AJ asked with ill-hidden interest.

Big Mac just looked at her for a few seconds before he once again started walking. “Ya know I don’t kiss and tell, sis.”

“Ah come on… was it Cheerilee?” AJ asked.

“No,” Mac answered.

“Cherry Berry?”

“No.”

“Candy Mane? Lily? Daisy?" Applejack began guessing more in a row.

"Nope, nope, nope, an' 'fore ya ask, not Rose either.”

“Aloe or Lotus? Aloe and Lotus?"

"Nnnope.”

“Sweetcream Scoops-"

"AJ, y'all gonna name every mare in Ponyville at this rate?"

"Maybe."

Mac sighed. "Figures...”

“Minty.”

“No.”

“Ooh, Zecora!"

"Ain't seen her since last month."

"Lemony Gem?"

"Nnnope."

"Spoiled Rich?"

Caught off-guard, Macintosh came up short on his next step, turning to stare at Applejack pointedly. "AJ, are ya kiddin' me? You get into the hard cider before y'all were gonna go searchin' for Sweetie Belle?”

“It's mah duty as yer little sister to heckle ya, so no. An' no Ah did not go drinkin' first, an' just fer that ya gotta come clean an' tell me. Who. Was. It?"

"Fine, fine. It was Rara."

"Ah knew it!" Two seconds later her smirk dropped as she stumbled, realizing what he'd just said, and it was her turn to glare at him. "Oh, y'all better not be ruttin' Rara, or I'm gonna beat your flank into the ground! Still wanna have a chance with her. She's just in denial 'bout me. Or maybe mares all around..."

"Well," Mac chuckled, savoring the look he'd earned, "as yer big brother, it's my duty to remind you that oldest sibling gets first dibs, 'sides, Rara's been crushin' on me since she was younger."

"Veeeeery funny, Mac," she growled in reply before silence set in. The night grew dark as they finally reached the main gates of Sweet Apple Acres. Macintosh didn't see the look cross her face before Applejack spoke once more. "Mare-Do-Well?"

"Oh fer the love of Celestia, AJ!”
(Insert at least two hours of brother sister’s shenanigans)

****

Sunday evening…
(Two days later if you’re not keeping up with the story's timeline)

Sweat was glistening off Big Mac’s chiseled body, making him look like a legendary hero of olden pony sagas, his muscles bulging while he used a sledgehammer to drive down another pole into the ground. After having looked at the toolshed way back amongst the acres of Sweet Apple Acre’s orchards, he had come to the conclusion that he would not be able to accomplish what he wanted by just rearranging the insides. Instead he was now building an extension in the back.

Extension might have been a mild word for what he was doing here; after all, the new room would be over three times the size of the original building.

It was going to be a large room in the back with no windows, plenty of straw in the walls for extra soundproofing, and — most importantly — plenty of space for Big Mac and Sweetie to fuck each other silly. He was also going to put in fittings for more adventurous sex down the line.

Big Mac had already realized that Sweetie Belle's prolific reading of sex magazines had given her a rather skewed view of the subject, especially in terms of what the mare should consent to. That was one thing Mac was glad for: He'd have the chance to set her straight on safety in bed. Eventually. Still, the possibilities presented by an eager young filly were just too intriguing and enticing. And on the other hoof, he had no intention of involving her in anything dangerous, and his conscience would never let him be cruel to her… even if she asked him to be.

With a great grunt, the last foundation pole was hammered into place. Big Mac looked up with a smile; this place was going to be perfect.

“Howdy, Mac!” a very familiar voice said from amongst the apple trees.

“Howdy, Bloom,” Big Mac answered his little sister.

When he turned around, the big red stallion saw that she wasn’t alone. Scootaloo and Sweetie Belle were with her. His green eyes lingered on Sweetie Belle’s tender flanks for just a little too long before turning back around to continue his work. “What can I do you three for?”

“Oh, we’re just bored!” Apple Bloom complained. “So we decided to look around the Acres to see if we could find something interesting… what are you doing?”

Sweetie’s tight ass… Big Mac thought with a smile.

As Big Mac looked at the three fillies, he could see Sweetie Belle's eyes lingering on his crotch, and he was pretty sure he knew where the idea of searching the Acres had come from.

“Just expanding the tool shed a bit, it’s been too small for a while,” Big Mac said while he continued to work.

“Really?” Apple Bloom said, looking a bit perplexed. “AJ and Granny haven’t mentioned it needs doing.”

“Welp," Big Mac said as he lifted a staggering quantity of planks with frightening ease, "Who is the pony most likely to be workin' out here?"

"You are," Apple Bloom said without hesitation.

"So who's most likely to know the tool shed needs expansion?" Big Mac asked before dropping the planks with a loud crash.

"Er...you are?" she answered again once her ears stopped ringing.

"Eeeyup!" And with that Big Macintosh went right on working.

"Well, alrighty," Apple Bloom conceded, the conversation dropped.

"So, do you need help?" Scootaloo asked excitedly. "We could be Cutie Mark Crusaders House-Expanding Helpers!"

"Renovators!" provided Sweetie Belle.

"Nnnope," Mac replied immediately.

"Aw, c'mon, big guy!" Scootaloo tried.

“Let’s leave him to it girls.” Sweetie Belle intervened. “We shouldn’t get under hoof at the farm; you both know AJ will chew us out if we do.”

Scootaloo looked a bit disappointed while Apple Bloom physically shuddered at the thought.

“Yeah, you’re probably right, Sweetie. Besides it's getting late. We should probably all head home now anyway,” Apple Bloom said with conviction.

“Oh, come on, girls. It’s not that late,” Scootaloo protested.

“I don’t know,” Sweetie Belle said while looking at Big Mac and licking her lips — something the two other girls didn’t seem to notice. “We should probably head home; it’s a school day tomorrow, after all.”

“That sounds like the responsible thing to do,” Big Mac said from where he was working, although his eyes were lingering on Sweetie Belle again. The small smile the two of them were sharing said that something completely different was about to happen. “It is a school day tomorrow, Apple Bloom. Go home and get to bed early — we don’t want you to be tired tomorrow.”

“Do I have to?” Applebloom now protested, sure it might be time to head home, but going to bed?

Big Mac looked like he was thinking it over and then gave a sigh. “Well no, you don’t have to go to bed already, but I do think it’s time for you girls to head home.”

“Ah, pony feathers…” Scootaloo said in a bit of annoyance before glaring at Sweetie. “I told you we shouldn’t have made ourselves known; now we can’t do any more fun stuff today!”

“Well, I’m tired anyway,” Sweetie said, giving a good impression of a yawn. “I say we call it a day and see each other at school tomorrow.”

“Fine! See you guys tomorrow then. I’m just going to pick up my scooter at the clubhouse,” Scootaloo said with a huff before storming off between the apple trees.

“What’s got her tail in a twist?” Apple Bloom wondered. “Well we’d better head off as well, Sweetie.”

Sweetie Bell was looking longingly at Big Macintosh, trying to come up with some reason to stay but drawing a blank.

“Go on ahead Apple Bloom,” Big Mac suddenly chimed in from where he stood measuring out planks for the walls. “Rarity needed to borrow some tools fer somethin' or other, though. I'm gonna keep Sweetie just a few minutes an' send her home with 'em. That alright with you, sugarcube?” he finished, giving her a thinly disguised look.

“Oh!” Sweetie Bell said, her expression brightening notably. “No problem Big Mac! Love to help handle your tool! Tools!”

“I don't mind waitin' either, Mac,” Apple Bloom tried, a bit disappointed at trotting off alone and completely missing the slip of Sweetie's tongue.

“No, you go ahead!” Sweetie said with a big smile, maybe overplaying it a little bit. “I’m sure I can handle this on my own, besides… eh… you need to brush your teeth!”

Apple Bloom looked at Sweetie with a raised eyebrow. “Say what now?”

“Ehhh… you… you really have bad breath! So you really need to brush your teeth!” Sweetie explained, looking very flustered, and grinning a bit too wide.

Apple Bloom looked at Sweetie with more than a little doubt before she put her hoof to her snout and breathed out and tested her breath. Then her eyes went wide. “Wow, okay… Maybe that home-made chili cooking cutie mark we tried for earlier today wasn’t the best of ideas,” she said with a blush. She looked at Sweetie with annoyance. “And you were the only one of us who didn’t try it!”

“Well, I saw how you two reacted, and then it wasn’t such a hard choice not to try it,” Sweetie Belle fired back.

“Okay! Okay! I get it, geez!” Apple Bloom said as she started to head off back towards the farmhouse. “See you tomorrow, Sweetie, if you can stand our bad breath!”

“Hey! I’ve been with you all day today, haven’t I?!” Sweetie yelled after Apple Bloom’s retreating form.

She heard a deep chuckle behind her. Big Mac was sitting with his back towards the shed, just enjoying the interaction between the two little friends. Sweetie immediately grinned widely, now looking at Big Mac’s crotch openly. She started walking towards him while swaying her filly flanks widely. “Why, Mac—”

Sweetie Bell was cut off by Big Mac shushing her and motioning for her to sit down. Looking a bit perplexed, Sweetie nonetheless complied. Mac nodded and lifted his gaze towards where Apple Bloom just left.

A minute passed and then there was the sound of hooves coming running towards them. Big Mac smiled as his little sister ran up to him and jumped into his four hooves giving him a fierce hug.

“Good night, big brother! But remember, you promised to read me more of my story tonight!” Apple Bloom reminded him, sitting trapped within Big Mac’s powerful hug.

“Of course I remember.” Big Mac said soothingly, “I’ll be back when my work is done, and I’ll read your whole chapter if you don’t fall asleep during it.”

“You’re the best!” Apple Bloom cheered and gave Big Mac a chaste peck on his cheek.

Big Mac then sat Apple Bloom back down again, and with another quick goodbye to Sweetie Belle, she was off amongst the trees once more.

“Ain't gonna say you were right 'bout her breath, but you were right." He chuckled, and then saw the questioning, and slightly envious, look on Sweetie's face as she stared after the retreating form Apple Bloom, so he explained. "AJ and I take turns readin' her bedtime stories. She an' I took to doin' it ourselves since we knew she wasn't gonna have it otherwise. 'fore we knew it, Ah think AJ an' me realized we liked it much as Bloom did, so we ain't stopped yet...even if y'all're old enough to be gettin' yer cutie marks soon."

Sweetie Belle couldn't even remember the last time Rarity had done the same for her, nor her parents who left the two sisters together more often than not. Mac continued, "An' since it's my turn tonight, Ah figured she'd be sweetenin' me up so I'd read as much as she wants.”

“That… actually sounds nice,” Sweetie Belle said with a sigh.

“Well, speakin' of bein' all sweet and suckin' up,” Big Mac said before he gently grabbed Sweetie’s cheek and brought it up so their lips could connect. As their lips locked together, Big Mac’s powerful tongue immediately made its way into the still less experienced mouth of Sweetie Belle.

The kiss was long, deep and hungry from the massive stallion, the little filly doing all she could to not just be washed away by the pleasure she was drowning in from the make out session.

As the kiss broke, Sweetie Belle was panting heavily, now laying on her back. Stars literally shining in her eyes. Above her, Big Mac looked down at his little filly lover, clear intent in his eyes.

Big Mac smiled down at Sweetie Belle beneath him — her wonderful white fur, almost glistening in its pristine condition, her emerald green eyes, so much like his own, that little frilly cute pink and purple mane. Sweetie Belle was the very picture of youthful innocence… and Big Mac was going to savor the sight, sound and sensation of her wrapping around his massive dick.

Sweetie Belle was, after all, far from the innocent picture of fillyhood she often portrayed. They may not have been able to sneak off and bang each other yesterday, like both of them had wanted, but some questions had been answered during their all-too-brief time together nonetheless.

First and foremost, how many stallions had Sweetie fucked before him? The answer had almost floored Mac. Forty-two cocks had spread her filly lips wide, thirty-seven had stuffed their dicks in her underaged little pink pussy, and twenty-one throbbing shafts had been squeezed deep into her tight little asshole. And that was without repeat visits counted in. Sweetie knew this because she had a little black book where she described what she did during every session and rated them against each other.

This succulent, ravishing but still somehow innocent looking filly, who was at this very minute smiling up at him, was a full blooded pro at taking cock in any hole she wanted. It was no wonder Sweetie Belle had been able to take the hard fucking Big Mac had given her their first time together. Okay, not to say Sweetie took his monster of a dick in her ass without effort. Still Mac hadn't yet met the mare who didn't whimper the first time he spread her asshole wide. And only three who took him happily now, and that was still only after several tries. Every pony except Zecora, who technically was a zebra, had whimpered the first time Big Mac fucked them in the ass.

Most mares he fucked anally were doing it on a dare. Or as a nice (for him) form of competition between friends, to see who could make him fuck them hardest in the naughty place. This happened rather frequently, all things considered. Especially when he was in bed with multiple, often intoxicated, mares wanting some sexy fun adventure for a night. Those little groups would push each other farther than any one of them would have gone on her own.

“Mac, are you going to fuck me or not?” Sweetie suddenly said, snapping Macintosh out of his reminiscing, from where she was laying on her back with her front hooves adorably pulled up to her chest, looking up at him with anticipation.

Big Mac grinned down at the petite little filly, who looked more than a little perturbed now at the current lack of massive dick in her tiny tight pussy.

“Oh, I'm gonna fuck ya, alright,” Big Mac said with all the confidence in the world as he felt his cock starting to swell and pulse between his thighs, eagerly awaiting the tight fit of Sweetie Belle’s underage snatch.

“Come on, Big Mac…” Sweetie said in a seductive tone from where she lay on her back, spreading her back legs apart for Mac’s viewing pleasure. “Won't you taste my magic potion? One taste and you’re mine forever!”

“Really, now?" Big Mac replied with a chuckle and lay down just behind Sweetie Belle’s widely spread hind legs. “Yer makin' me an offer no stallion could turn down.” And with that, Big Mac grabbed Sweetie’s legs, locking them in place, before covering her little filly cunt completely with his mouth, plunging his tongue as far into Sweetie’s pussy as he could.

Sweetie’s head fell immediately as her back arched off the ground, a shrill cry of pleasure sounding out amongst the apple trees. Macintosh’s broad tongue pushed as far inside Sweetie’s pussy as it could reach, twisting, undulating and grinding against cingular spots in her cunt far harder than any cock could ever hope to do.

Big Mac had to pin Sweetie in place rather harshly so she wouldn't squirm away in her throes of pleasure. He continued to eat the filly’s little vagina out, marveling at how tightly her pussy clamped down on his tongue when she climaxed. Shrieking loudly, her back legs closed around Big Mac’s head with surprising ferocity, pressing Mac’s tongue deeper still into her pulsing cunt.

Mac hummed in delight as Sweetie’s moist core leaked filly cum straight into his waiting mouth, and he didn’t let up on eating out her tight pussy. Big Mac pressed on through her whole climax, extending it far longer than it who'd have lasted otherwise.

When finally Sweetie Belle’s climax tittered out, she just lay there panting as Big Mac slowly dragged his tongue from the bottom of her vagina, parting her pussy lips slightly as he continued up to her swollen clit. Big Mac captured the little ecstasy-inducing pearl and suckled it tenderly, making Sweetie Belle gasp in pleasure, only for Big Mac to start over again.

“Oh, fuck… oh, fuck…” the well-pleasured filly was finally able to say between pants. “Oh, fuck me.”

“Since you insist,” Big Mac said with a grin as he started to kiss his way up Sweetie’s soft stomach.

In surprise Sweetie looked down as her big red stallion lover tenderly kissed her chest. “What-mmph!”

Sweetie was cut off by Big Mac’s lips being pressed against her own. His tongue darted into the off guard filly’s mouth, sharing her own flavor of filly juice with her. Sweetie Belle had never tasted herself in this way, it was a tart taste. Their moist tongues sliding against each other making loud sloppy noises throughout their make-out session. Fortunately the little filly was extremely turned on by all this, finding it so hot she almost climaxed again.

As the kiss ended, she lay on the ground panting while Big Mac stood up, exposing his large dick for the exclusive viewing pleasure of Sweetie Belle. She licked her lips as Big Mac let his cock swing back and forth, the little filly’s eyes glued to the impressive piece of meat on display.

“Fu… fuck me, Big Mac,” Sweetie said desperately. “Gimme your huge cock… I need it in me, please don't make me wait!”

Big Mac hummed in approval at Sweetie’s wanton display, as she was once again spreading her legs wide for him, more or less begging him to fuck her then and there on the rough ground.

Instead, he turned toward the stack of planks, to her disappointment. He then pulled a sheet of thick fabric over the planks, folded it over on itself a few times, and finally picked her up with loving care to place her on her back on the improvised bed. He looked down and nodded in satisfaction; she'd be comfortable here, and her tight little pussy was at the perfect height to be ravaged.

“Try an' keep from bein' too loud, Sweetie,” Big Mac said while he nuzzled her, “...if ya can. I'm gonna fuck ya just as hard as ya want… an' not gonna stop till I cum.”

“Oh yeah,” Sweetie said in a whisper, “Do it. Fuck me, hard as you can, don't hold back 'cause you know I can take it." Her eyes glinted playfully. "And if I can't keep quiet myself… maybe you know some way to keep me quiet.”

“Eeyup,” was all Big Mac answered as he stood up tall, placing his forehooves above and on either side of Sweetie’s head, his impressive stallionhood bouncing right in front of Sweetie Belle’s dripping cunt.

He took a deep breath as his monster of a dick lined up with the pussy of the little filly. Big Mac gripped Sweetie by the shoulders, having learned the lesson from last time. Then he looked down on his massive shaft, the head of it completely covering Sweetie’s little pussy entrance.

Oh, this is going to feel fantastic, Big Mac thought as he lowered his stance, spreading and digging his back hooves into the soil for better traction before starting to push his mighty cock against Sweetie’s moist cunt.

Mac moaned happily as Sweetie’s nether lips were stretched far wider than any pussy lips her tender age should ever be spread, relentlessly forcing his massive cock deeper and deeper into the moist, burning hot, and most importantly, tight little pussy.

Sweetie whimpered and moaned in equal measures as she was filled with what seemed like obscene amounts of hot and pulsing stallionhood. She desperately bit her own lower lip to keep from crying out in both pleasure and pain.

But when the head of Big Mac’s cock smashed into Sweetie’s cervix, she was powerless to stop herself from roaring out in what seemed to be pure ecstasy, even with the jolts of pain and lingering ache from each time his broad tip hit the bottom of her small passage. It just made the constant waves of pleasure that much more enjoyable to her. Big Mac’s massive dick was just so fantastically big, and it spread her underaged cunt so far it made her feel completely and utterly full to bursting. And Sweetie Belle loved it, wishing nothing more than to be utterly fucked into oblivion by her massive, red and wonderful special some pony.

Big Mac took a big gulp of air, his whole head ringing in shock at the amount of undiluted pleasure coursing through it. He thought he was ready for the feeling of forcing his cock back into his little filly friend’s tight core, but even after having done it before, he was still completely overwhelmed by the sheer amount of pleasure enveloping his stallionhood. Lightning flashed up his spine, straight into the pleasure center of his brain.

“Yes!” Big Mac hissed through clenched teeth. “So... good…”

The big stallion looked down at his wonderful filly lover and smiled at the sight of her squirming beneath him in cock-induced ecstasy, Sweetie’s green eyes almost rolling up into the back of her head.

Big Mac lowered his gaze farther down and marveled at how obscenely stretched out Sweetie’s pussy was around his massive dick. It looked as though anything more, whether he'd worn a condom, or just throbbed especially hard inside her, which was a very real risk, would be too much and the young filly beneath him would split in two.

Big Mac gritted his teeth and pulled back until only the very tip was left inside Sweetie Belle. Then with considerable strength, he pushed forward again, not stopping until he was once again grinding against the filly’s straining cervix.

Somehow he registered that Sweetie’s vagina now seemed to swallow over three quarters of his full length. Oh yeah… we'll get that pussy of yours takin' every last inch! Mac thought excitedly.

It looked like Sweetie’s young body was adapting nicely to Big Mac’s big tool. He had hoped she would, but never did he expect it this quickly. Although, she had fucked a lot of stallions, his larger than average cock might just have been the last push Sweetie’s cunt needed to really get growing.

Mac pulled out again, and started fucking Sweetie in a slow but powerful rhythm, giving the young filly’s over-stretched snatch time to adjust. And also giving himself the chance to utterly revel in the glorious feeling of his massive cock sliding in and out of Sweetie’s quivering, tight and wet velvety vagina.

Big Mac was moaning almost as loudly as the filly he was spreading wide. Sweetie Belle's moans, gasps and even her little groans of exertion were music to his ears. He could feel every overstretched, velvety-soft fold inside her pussy slide against his massive shaft as he pumped it in and out of her.

Every time his big cock was shoved deep inside Sweetie’s succulent young vagina, pussy juices were splashing out of her tight filly cunt, drenching Big Mac’s shaft in her wonderfully perverse liquids which also ran in streams down her now soaking wet ass and tail.

The squelching lewd sound emanating from the filly’s overstuffed pussy every time Big Mac’s cock was shoved deep inside Sweetie’s succulent young body was probably the most erotic sound Macintosh had ever heard.

Suddenly Sweetie's voice rose sharply. Big Mac might have wondered if he'd suddenly gone too hard on her, but those louder cries were pure ecstasy as her pussy clamped down on his dick, another orgasm shaking her fillyhood to its core. She grew louder each time he moved, and when the overwhelming stimulation had pushed her to the point he was sure she would get them caught, he finally clamped a broad hoof over her muzzle, muffling the sound of her continuing climax.

Air blasted out of Big Mac’s nostrils as he continued to fuck Sweetie Belle, but even as amazing as it felt, he just needed to fuck her harder. He was still holding back, and that just wasn't enough for the stallion as his arousal built with every thrust.

Abruptly he pulled free and rolled Sweetie Belle over, the filly squealing as she felt suddenly, dreadfully empty. He grabbed her by her flanks and pulled her to stand, front half slumped forward onto the makeshift pallet and trembling hind legs keeping her hindquarters lifted. It was a perfect, classic position, one that begged 'rut me', and the massive red stallion was ready to do just that.

Big Mac pinned Sweetie in place by shoving her chest against the rough fabric beneath her with one hoof, with the other he grabbed Sweetie’s soaking tail, lifting her twitching young body up to keep her standing. It wouldn't do for Sweetie Belle to collapse before Big Mac was done fucking her brains out.

With that taken care of, Big Mac viciously forced his massive shaft deep into Sweetie’s cunt, making the little filly scream in absolute glee as another massive orgasm rocked through her.

Big Mac didn't stop for a second as he pulled back and then started to brutally fuck the little filly beneath him. The speed and the ferocity the red stallion used would have been breathtaking to witness. The sexual energy rolling off the two lovers could almost be felt at a distance and even tasted in the air.

His dick was a blur as Macintosh fucked Sweetie harder than he had ever fucked any pony in his life, sweat dripping off his chiseled body while he rammed his cock into the filly’s tight pussy again and again. Sweetie’s ecstasy filled wailing travelled far out over the Orchard.

However Big Mac didn't care, mostly because his own roars of ecstasy were easily droning out the cries of the little filly’s continued orgasmic high.

Macintosh kept on savagely fucking Sweetie Belle for almost ten minutes before his own climax finally came. With a bestial scream Big Mac’s white stallion gravy spilled into Sweetie’s overstuffed pussy, every thrust into Sweetie’s tight cunt now sending gushes of Big Mac's thick cum squirting out from the wet seal her pussy made around his cock, to run messily down the filly's trembling legs.

As the last of his potent stallion spunk was being pumped deep into the young little filly’s overstuffed cunt, Big Mac grabbed Sweetie Belle and lifted her up, holding her whole body in his fore hooves. The massive stallion then proceeded to lift the little filly up and then push her down his desperately pulsating shaft, wanting nothing more than to extend the unbelievable amount of pleasure he was experiencing.

Now using Sweetie Belle as nothing more than a fuck tube for his own desire, Big Mac’s savage fucking nonetheless started slowing down. Still, by the continued cries of sheer undiluted pleasure emanating from the filly, Sweetie Belle wasn't complaining in the slightest at the treatment.

At last Big Mac fell back, still holding Sweetie Belle tenderly against his muscular chest. Both of them gasped for breath as they lay there in post-orgasmic bliss, Big Mac on his back, looking up at the early evening sky smiling in contentment, Sweetie Belle still occasionally squirming in complete sexual satisfaction.

They lay like this for several minutes before Sweetie broke the stillness. “That was… wow…”

“Mmmhm…” was all Big Mac answered.

“Will… will it be like this every time?” Sweetie asked hopefully while Big Mac’s softening cock started to slowly shrink inside Sweetie’s still occasionally clenching pussy.

“Oh dear Celestia, I hope so…” Big Mac said with proud satisfaction before his voice softened. “But ah don't think anypony could rut that hard, or that long, every time they go at it.”

“Awwww…” Sweetie said in disappointment, before a smirk crossed her face. “We are still going to try, right?”

“Eeyup,” was all Big Mac answered.

“Good…” Sweetie said softly as she tried to stay awake, the intensity of the hard fucking she had just received starting to catch up with her.

“Rest up a li'l, Sweetie, alright? But when yer ready, how about you use that mouth of yours an' clean me up before we bring ya... home...” Mac trailed off as he realized Sweetie had already dozed off in his embrace.

Well then… Mac thought with a smile and started carefully humping the semi-erect cock still buried inside the little filly’s wonderful pussy. Hopefully he would be fully erect when she woke up in a few minutes, ready for a nice round of oral satisfaction.

That’s going to feel really good too… Big Mac thought happily while he lovingly stroked the sleeping filly on his chest, simultaneously feeling his stallionhood slowly getting hard inside her vagina again.

****

Not far from the two recovering lovers, a pony stumbled on wobbling legs as she retreated hastily from the display of the most intense, hoof-curling sex she'd never even dared imagine. Her own pussy dripped with need, and her hoof was still soaked with juices from where she'd furiously rubbed herself as she watched. But how to come to terms with what she'd just witnessed?

That… That was so... wrong, wasn’t it? It's supposed to be wrong, isn’t it?! Her thoughts raced as she debated whether to depart now, or just give in and rub another one out so she could think clearly. Why am I so fucking turned on by it? I'm not turned on by S... Oh, fuck, I AM. The thought, at first a bit troubling, turned into a white-hot flash of arousal. Oh, that would be so FUCKING hot!

The pony desperately needed something in her cunt right now. Looking around herself in more and more desperation to find something, anything!

“Oh, for fuck sake…” she hissed, and started racing off. She needed to take care of this; whatever she should do about her new knowledge would just have to wait!

****

The End
For now…

Chapter 3 A Quickie in the Market

Big Mac’s o so Sweet Surprise

Chapter 3

A Quickie in the Market

****

Big Mac sighed in contentment while the mare walked away with her purchased apples. He hadn’t seen her before in Ponyville, but by the way Pinkie Pie was sneaking after her, she was about to receive her official welcome.

The day had been quite good, his newly built Apple Store having drawn quite a few visitors during the day. Many of them also commenting on how very happy Big Mac was looking with the changes.

And he should be! The Apple family would no longer sell their wares straight off the wagon like they used to. He now had an actual front with a counter which wrapped around him in a horseshoe-like shape, and apples piled high to his left and right. Even his considerable size was hidden behind the mounds of apples.

Above him he had a canvas sheltering him and the apples from the sun, and it also stretched out in front of the stall so his customers could conduct their business in the shade. Behind him was an actual wooden wall with a door.

He groaned in pleasure as he felt the tender lips of the filly hidden beneath the counter slowly glide up and down his erect cock. He had already emptied himself in her sweet little mouth one time, but Sweetie Bell had only kept on sucking him off, quickly bringing him back up to full erection.

“Oh yeah… right there, Sweetie… yer mouth feels so good,” Big Mac said in a low whisper while he reined in his expression, trying to make sure no pony would suspect what was happening out of view.

Sweetie Belle twisted her head from side to side, as she slowly worked her wet mouth tightly around Big Mac’s generous girth. The sweet and salty seed still streaking some of his cock coaxed pleasured and very aroused hums from the filly, those little noises sending waves of euphoria straight to Big Mac's brain as they tingled against his flesh.

The great red stallion closed his eyes in order to enjoy the feeling of the little filly continuously giving him a blow job even better. They had been together for almost a week now since their wonderful first time in the public bathrooms at the Mayor's office, which kicked off their forbidden relationship.

Big Mac could only smile while he let his thoughts wander over the past week. He and Sweetie Belle hadn't gotten a moment alone since that Sunday evening… but oh Celestia if she hadn't given him the most amazing fucking in his life.

Ever since then though, they had been unable to find any place to have sex, to both their frustrations. The risk of being discovered had always been too great. Finally it had been Sweetie Belle who had come up with a rather lewd and unorthodox suggestion.

At first Big Mac had been shocked, but the more he thought about it, the more it seemed possible that it might work. And with a few tender kisses and encouraging words from Sweetie Belle, Big Mac had set to work implementing the plan.

It had taken him only three days of simultaneously selling apples and building before his new stall stood proudly in the marketplace whether the rudimentary Apple cart usually was. So today when Sweetie Belle had finished school, she had immediately come over to inspect his achievement.

It had been wonderful, and their plan of fucking somewhat in public seem to be a resounding success as Sweetie Belle eagerly kept sucking on Big Mac’s cock.

Big Macintosh had insulated the space for Sweetie Belle beneath the counter quite effectively, which, combined with her own efforts at keeping quiet, proved quite effective. As far as he could tell, not a single pony had any inclination that below the counter a little filly was sucking off the big red stallion, how was leaning heavily on the counter in front of him.

Now it was Thursday, and Sweetie had gotten off school early today. Big Mac’s little sister was back home at Sweet Apple Acres doing her chores, and Scootaloo was busy hanging out with Rainbow Dash.

This had left Sweetie Belle all the time in the world to sneak over to him, so a little after one o’clock she had entered Big Mac’s stall and quickly got to work pleasuring him.

“Excuse me Big Mac, but I am running a bit late…” A melodic voice said to the stallion while he sighed in contentment at the little filly’s quite considerable blow job skills.

The poor stallion nearly had a heart attack as his eyes opened and fell on Rarity, sporting a rather perturbed expression. Only many years of having a schooled, stoic expression kept him from breaking out into a coughing fit.

“Rarity!” He said loudly and happily to make Sweetie Belle aware of just who was at the stall, “…sorry, ah… Ah'm a million miles away.”

“Oh, I can see that, darling.” Rarity purred, her smile far too sweet for his liking, “Happy thoughts, I take it?”

Big Macintosh blushed and looked away, his coat mostly hiding his blush and his averted gaze almost hiding his eyes going wide at the unmistakable feeling of Sweetie Belle's tight little pussy slowly but surely sliding down the length of his cock.

Oh, dear Celestia! She’s doing that, now! Big Mac thought in panic as he had to grind his teeth in order not to moan out loud in pleasure.

“So, Rares, wh-what can Ah do for ya?” Big Mac asked haltingly.

“A dozen Granny Smiths, please, dear. I thought Sweetie Belle and I could bake some apple pies tomorrow night. That filly does so like apple pie and vanilla custard." Mac bit his tongue at that. "I wanted to do something as an olive branch, if you would. I've been so dreadfully busy this week and I've barely seen her at all! And after last weekend… well, I believe she's still a bit cross at me,” Rarity said with a sad sigh.

Big Mac gave a little grunt as Sweetie Belle shoved herself onto his cock in a particularly pleasant way before answering Rarity. “That's mighty sweet of ya Rarity, but… Ah thought all three of the CMC were gonna sleep over at Sweet Apple Acres this weekend?”

Rarity's eyes widened in realization before slapping a hoof to her forehead. "Oh heavens I had completely forgotten about that!”

“Well, don't ya worry, Rrrrrgh...R-Rarity, we'll take real good care of Sweetie Belle. Of all the girls," he amended, "An' they'll get all the apple pie they like. Ah just might spoil Sweetie an' give her all the custard she can handle, you have my word on that.” Big Mac said while trying to look innocent.

Sweetie Belle was really working his shaft right now, he had a small suspicion that the little filly was getting quite worked up by the thought of Rarity casually conversing with Big Mac while her not-so-innocent little sister was fucking him eagerly under the counter.

Big Mac actually had to discreetly lower one front hoof down and stop Sweetie Belle’s insistent fucking, or he would climax right in front of Rarity. And he strongly suspected not even his stoic face would be able to cover that up.

Luckily Rarity hadn’t been paying much attention, looking away in disappointment at the realization that Sweetie Belle wouldn’t be home this weekend when she had planned to apologize to her.

…Then Rarity realized that Sweetie Belle wouldn’t be home this weekend. "Oh, my… why, that would mean I could invite Fluttershy over! It's been some time since we've been able to just enjoy each other's companionship… and a day at the spa can only do so much, if you catch my meaning, dear."

The way Rarity was licking her lips at the thought of Fluttershy made Big Mac’s cock twitch inside of Sweetie Belle’s tight young pussy. It was a well-known fact within the Mane six and their families, that many of them had gotten close enough with each other that physical intimacy was a natural step forward. Big Mac had actually spent a few nights in the company of both Fluttershy and Rarity, even both of them at the same time, the pair making no secret of enjoying stallions and mares alike.

There was also no secret that Rainbow Dash and Applejack were quite thoroughly fillyfoolers, and in an intimate relationship with each other. Pinkie was, in her own unique word, supersexual… having had sex with both genders, and with numerous of Equestria's races. Last but not least, there were only rumors circulating about Twilight and Celestia enjoying more than late-night study sessions. Furthermore, since Luna’s return she had also been implicated in the latest gossip surrounding Twilight.

“Mac?” Big Mac heard Rarity’s voice say in concern.

Wait, how long had he zoned out again? “Ah'm sorry, Rarity," he said sheepishly. "Been a good day, but been a long one too.”

“No problem darling, I know how that can be,” Rarity said with a sweet smile. “Nevertheless, I will still need those apples for Fluttershy and myself.” Then she gave Big Mac a rather seductive look, “You are most welcome to join us if you like, dear. It's been quite some time since our last little… rendezvous.”

“Thank ya kindly, Rarity, an' Ah'm mighty tempted," Big Mac replied sincerely as he quickly loaded Rarity's apples into a paper bag, "But Ah got plans for the weekend already.”

“Well, that’s too bad,” Rarity said and picked up her order.

She turned as if to leave, but walked slowly, her hips swaying sensually and her tail offering fleeting glimpses of what hid just beneath. "Still, if you do happen by the boutique… you're more than welcome to come inside.”

The double meaning of Rarities words did not escape Big Mac for a second.

“Ah'll keep that in mind,” Big Mac called after Rarity as she disappeared.

He saw her give a quick smile right back before disappearing entirely. Mac then groaned in relief and pleasure as he leaned back from the counter to see Sweetie, once again thrusting herself onto his quite generous cock while she bit down on a convenient tennis ball, now thoroughly soaked through.

“Sweetie, we gotta talk about your timin', filly… an' did ya really bring that ball with ya too?” Big Mac said while he reached down with one hoof, but this time he grabbed her tail and started to thrust himself into the tight little pussy. He wasn’t angry, but he was definitely annoyed with what she had done.

Sweetie Belle spit out the improvised ball gag. “But I had to remind you who you belong to now,” she said and grinned up at him, her smile widening even further when she felt Big Mac start to fuck her as hard as he could in their current position.

They were both worked up by now, and it didn’t take many minutes before Sweetie Belle had to bury her face in the pillow Big Mac had thoughtfully provided her. Sweetie’s climax quickly rushed over her as Big Macintosh's massive dick plunged deep inside of her filly cunt. Big Macintosh followed close behind as Sweetie’s pulsing pussy clenched around his stallionhood oh so wonderfully tight, making the big red stallion blast his come deep into her wanting womb, all the while gritting his teeth in pleasure.

With a final deep shove into Sweetie’s moist core, Big Mac could feel himself finally run dry. As he let go of her, Sweetie collapsed to the floor, looking more satisfied than she had all day.

“Oh, that was just… what I needed… hah… can't believe how good… your dick feels… inside me...” Sweetie Belle said breathlessly as she lay and quite literally squirmed between Big Macintosh legs in the afterglow of her orgasm, Mac’s semi-erect cock still inside of her pussy.

Big Mac met her grin with his own mischievous smirk. "Ah'd hope so, 'cause I mean to stuff ya with it plenty more, Sw-”

“So, is your little playmate beneath the counter better than me? Hmmm…”

At the very familiar voice, Big Mac’s head snapped up, and the most fake smile ever spread across his face until his cheeks ached with the effort.

“H-hey there! Cheerilee!" The awkward silence filled only by his grin stretched on for an eternity of seconds before realizing he should say something. "What can Ah do for ya, Cheerilee?”

“Oh, Big Mac,” a cute little giggle escaped from Cheerilee, “you look so cute when you caught red hoofed.” Then Cheerilee narrowed her eyes, “But you didn’t answer my question you big mare magnet. Is your new plaything good, or will I have to come back there and show her how to really work your fun pole.”

“Well, she's mighty talented, Ah won't lie an' say she ain't,” Big Mac said with beads of sweat rolling down his forehead. Below the counter Sweetie Belle was holding her mouth closed with her front hooves, eyes wide in panic.

“Really…?” Cheerilee said while she looked at her sometimes lover. “I'll take your word on her talent. I'm also guessing she's younger… and since she hasn't come out to say hi, she must be bashful too. Are you sure you don’t need me to come back there and help out?”

“That’s a kind offer, Cheerilee, but this is all kinda new. We're... havin' our first weekend together comin' up, so we're makin' it special. An' fer now, just the two of us.” Big Mac said while he leans forward onto the counter again, making it all but impossible for Cheerilee to sneak a peek below.

“Very well Big Mac, I won’t keep pushing. But do come over later when you get the chance. Any chance... It's been too long since the last time," she spoke in a husky whisper. "I think we could even sneak in a quick fuck during recess...” Cheerilee said and darted forward giving Big Mac a quick peck on the lips.

“Now if you’ll excuse me, I was on my way over to the spa.” And with that Cheerilee turned around and started walking away.

“Wait, ya didn't need to buy any apples?” Big Mac called after her in surprise.

“What? Oh, no, I just got curious when I realized you were up to something over here. And I'm not the only one who noticed… you've made a few of the other vendors quite flustered,” Cheerilee answered with a big smile, before sauntering off.

Big Mac looked around, and Cheerilee was right: Two of the three vendors on the other side of the market--those who could actually see him behind the mountain of apples around him--were grinning widely. The last one instead simply blushed furiously, choosing to look off in a completely different direction.

“Alright, we haven't been all that subtle after all,” Big Mac said with a bit of worry.

“Do you think they know who I am?” Sweetie asked in alarm from below.

“Nnnope. Else they wouldn't be smiling at me,” Big Mac said flatly while he waved over at the other vendor’s, his very fake smile in place again.

“But how will I get out of here now? The minute I leave this will turn into a catastrophe!” Sweetie Belle squeaked in panic.

“Don't ya fret. Ah always bring what didn't sell back home, an' Ah got some crates to do it in. You just sneak in one of 'em, an' nopony's gonna be the wiser,” Big Mac said in a calm voice smiling down at his little lover.

“Oh! I can do that!” Sweetie Belle said a bit too loudly in relief.

“Shh! Not so loud, Sweetie. They can't see ya but they'll know yer voice,” Big Mac reprimanded.

“Sorry!” Sweetie Belle squeaked before clasping her hooves over her mouth.

With a sigh Big Mac brought the crates over, letting her to crawl into one, and not long after his wares were efficiently packed away on the cart, the two of them were heading off back to Sweet Apple Acres.

Once they had passed under the welcome sign, Big Mac knocked on the crate just behind him.

“Okay, you can come out now,” he said in his deep calm voice.

Sweetie Belle opened the lid on the crate and crawled up to sit on the top instead.

“Wow, that was close,” the young filly muttered.

“Eeeyup... We oughta be more careful for a while,” Big Mac stated solemnly.

“Yeah, but at least will have the love nest tomorrow,” Sweetie Bell answered cheerily.

“Eeeyup…” Was all Big Mac said, his smile once again genuine when he looked back at Sweetie Belle.

“So I’ll see you tomorrow just as we planned?” the little filly asked with anticipation.

“Eeeyup, soon as Scootaloo and Apple Bloom fall asleep, you just get yer pretty little flank downstairs, out to the barn, an' Ah'll be waiting for ya," Big Mac confirmed as his gaze swept over Sweetie Belle. He grinned. "But ya might wanna stop by the pond? before ya head home. You got some custard on yer cute muzzle," he said, making it a point to tease her about that now that Rarity let it slip. "An' yer kinda leakin' more back there too.”

Sweetie Belle looked down at where she was sitting, noticing immediately that a little puddle of filly juices and stallion spunk had formed beneath her. “You really did fill me up good Mac…” Sweetie said as she looked back at her stallion lovingly. “Can’t wait to see what you have planned for me tomorrow.”

With that Sweetie jumped off the moving cart and started to trot off between the trees, making extra sure Big Mac could see his come leaking out of her pussy and down her legs while she moved away.

Humming in approval, Big Macintosh nonetheless turns back towards the farmhouse. “Oh, yer gonna see alright, ya insatiable little filly" he chuckled to himself, "an' it's gonna be a long night.”

And with great anticipation, the big stallion started to think of the last few items he need to get for his and Sweetie Belle’s first real get-together, where none of them would have to hold back anything.

“Yup... it's gonna be wonderful.”

Unbeknownst to the two lovers, wide and eager eyes had followed them the whole way, and the mare grinned wide as she watched Sweetie Belle sneak out of the crate.

Jackpot! That wasn't just a one-night-stand… the big lug's seriously fucking Sweetie Belle any time he can get away with it! She thought excitedly. Now… how can this work out for ME?

She hummed as she mulled it over, slipping away unnoticed. A plan soon began to take form in her head.
