Stumbling upon some new, exciting and kinky information, the CMC can’t wait to try out whatever this ‘cock worship’ thing is…

With the Cutie Mark Crusaders unintentionally coming across information of something called ‘Cock Worship’, they think it’s the perfect way to get their cutie marks (plus some part of them really wants to try it out). All they need now is some stallion to test their newfound knowledge on, and with her sister and grandma out of town, Apple Bloom knows just the stallion to have their fun with.

Sexual stuff happens, including a fiery foursome and some incredible incest.

All characters are of the age of consent (by pony standards).

Cutie Mark Crusader Cock-Worshipers!

Happily, cheerily and optimistically, three fillies trotted through Ponyville at a rushed pace after they’d just had their dinner. The trio all had smiles on their faces, them beaming as the sun beamed down on them. They’d been looking forward to this for a whole week now, it finally being time.

What time you may ask?

Why it’s Twilight time of course! And the fillies were desperate to see her again. They had been working endlessly all week to try think of new ways to get their cutie marks, but nothing worked, the few things they could come up failed catastrophically (like their shenanigans usually did) and they had been miserable because of it. But this day of the week is the day when they get to spend time with the Twilight Sparkle, and she could always come up with some amazing idea to help them.

Slowing down to a walk, Sweetie Belle thought about how they were relying on the princess so much, needing her to come up with something to help them. Will she even be able to help us? Stuck in her head, she hadn’t noticed her change in speed, but the other two had.

Turning their heads at the same time, Apple Bloom and Scootaloo looked back, the white pony that was walking in between them now having disappeared and seemed to be loosely following them, staring at the dirt road they were on while her muzzle scrunched up adorably in concentration. Spinning in unison, they moved to face her, analysing her in her suddenly switched state. “Hey Sweetie’, you okay?” Scootaloo was the first to act despite them both being curious.

Startled, her head snapped up, seeing her two friends with concerned faces as if they were worried she was upset. It was sweet that they were such good friends to her. “Hm?” Catching up to them, they all started walking again, not in silence now but chatting. “Oh yeah, I was just thinking, what if Twilight doesn’t have anything for us? Rarity brought up how she’s been really busy as of late.”

Upon expressing her concerns, they breathed out a small sigh of relief, knowing now that nothing was wrong with her. “Aw don’t worry, ah’m sure that she can help anyway, it is Twilight time, she always does something to help.” Apple Bloom reassured her in a consoling tone, it working and Sweetie Belle cheering right back up.

Continuing the journey they soon arrived at the Golden Oak library, the delightful tree being where they needed to be. Strolling up to the door, they looked at each other wondering who was going to knock, not that it mattered. Apple Bloom did though and the three waited outside impatiently for the princess to greet them, them hearing hooves get closer and closer as they nearly bounced on the spot.

A purple aura opening up the door, Twilight appeared before them as the door swung open quickly, them having to do a double-take to check if they saw her correctly the first time. The unicorn’s fur was messy in places and her mane was a mess, she had slightly bloodshot eyes and was slightly panting, in other words she looked like she hadn’t slept in a day or two, and she hadn’t. “Oh, girls, it’s you. Don’t think I’ve forgotten about what day it is.” Stepping to one side she raised hoof up, gesturing them inside politely, the mare was acting normally, despite the disheveled state she was in.

Awkwardly moving in, looking at Twilight and wondering if she was okay, their faces showing their confusion and concern, something the Princess of Friendship picked up on. “Hey Twilight, ‘you okay?” Heads tilted, the princess was interrogated by the orange filly in front of her.

Smiling, the older mare eased their worries. “Oh, I’m more than fine Scootaloo, it’s just that I’ve been given some very important work to help Princess Celestia with, you’re sisters might’ve mentioned I’ve been busy as of recent…” Guiltily chuckling, she scratched the back of her head with a front leg, sad that she couldn’t have made time for them. At least she hadn’t left them with entirely nothing to do though, it was her job as their occasional tutor to teach them and she made sure she would, having a backup plan. “But don’t think that I don’t have anything for you fillies.”

They had been listening to her before, but now they were focused entirely on her, nearly bouncing on the spot again as they hung on her every word. Expectantly they looked up at her, Twilight’s heart melting a little at the sight.

Aww, they want to learn almost as much as I did at their age. She a little confused but she got the spirit. They did want to learn, not for the sake of learning, but for whatever cutie mark opportunity could be given, and they’d take anything at this point. “Well, it came to my attention that you three young mares have recently become of age, which means that you three are now technically ‘legal’.”

It threw them off, they didn’t know what a lot of that meant, but they weren’t perturbed enough to get their hopes dwindled just yet. And still looking up at her, they showed their anticipation.

Giggling cutely, Twilight gave in, explaining the rest. “Well, you pony mares have only just reached what’s known as the age of consent by pony standards and-“ Out of habit, the alicorn could close her eyes when explaining things, but upon opening them again she saw instantly that they weren’t here for a lecture, wanting her to get this over with. Tutting and rolling her eyes at their antics, her smile not leaving her, she cut to the chase, once again closing her eyelids while talking. “Alright fine, I should’ve left a book in my bedroom upstairs for you three, I know it isn’t much of a ‘cutie mark opportunity’ but I think you could really learn some interesting stuff about your-“ She opened her eyes… and they were gone. They just took off upstairs without me noticing. It didn’t need much more thinking about to take the information in. Yep, should’ve seen that coming.

She shook her head to herself, looking up at the open door atop the stairs that they somehow noiselessly escaped through, surely finding the book by now. And with that she turned back around and headed through a door to the basement, happy the rambunctious trio could distract her before she got back to another gruelling day of working away.

They knew it was rude but they couldn’t help it, their ears heard ‘I should’ve left a book in my bedroom’ and they didn’t need anything else, already having run away by the time Twilight stopped zoning out and looked back at them.

“So what’re we lookin’ for?” Leaving the door open behind them, the cutie mark crusaders practically dived into the room, too busy ransacking the place to think about anything else. “I know it’s a book but what kind of-“

“Found it!” Upon entering the room, they had expected their temporary tutor to leave it out for them, but instead they had to go searching, Scootaloo being the one to call the others to her. Despite Twilight being a mess herself, the room was immaculate, there not being much to go through to find their desired book.

Having opened up Twilight’s bedside drawer, the orange filly had looked inside, indeed finding a book in there. Sprinting to her they peered in it too, all three staring at the book and being stunned into silence. Wildly, blushes emerged on their faces, the red taking over them as their eyes remained glued to it. “…Umm…” Making her horn glow a light green, Sweetie Belle picked up the book with her magic, the sight somehow making the blushing even more prominent.

On the hardback book read the words ‘Stallion Cock And How To Worship it’, boldly and abrasively telling them exactly what was in there and exactly what the princess apparently thought they should learn. Under the title was the underneath of a pony stallion, his erect member fully displayed from his tip all the way down to his balls.

The three’s mouths were in the shapes of ‘o’s, none of them looking away for minutes on end while they each had different thoughts running through their mostly-innocent heads. I-I-Is this really what the princess wants us to learn? Sweetie Belle’s blush stood out the most on her white face, they’d been taught about the birds and the bees at school, but only the basics, obviously. She was doubtful about all of this, but even then she couldn’t help but admire the picture on the book.

Apple Bloom was doing the same, going over it and taking in every detail of the length in front of them. Subconsciously and unaware of it happening, her tongue licked her lips, wondering what a real-life one would be like while still staring at it, choosing not to question the strange thoughts as they began emerging.

And Scootaloo was trying her best to not think about what would be inside there, curiosity making her fantasise about what the tome of knowledge held for them and what interesting things this could all lead to. On her back, she never noticed her wings spread wide, hard and erect.

All three bodies had heated up on the reveal, them feeling arousal for the first time in their lives while they felt their virgin pussies get wet, telling them to help out the unfamiliar sensation without them having any knowledge of how to… yet.

Sweetie Belle was the first to come to her senses, getting out of the curious thoughts her mind was suggesting and remembering what was happening as well as where they were. W-We’re still at Twilights! Levitating the book closer to her and making the others zone back in too, she looked at them both before her own eyes darted away from theirs, them all still a bit embarrassed about this. “We- W-We should…”

Getting the hint, they agreed in the same stuttering way. “Y-Yeah, we should, umm…” “I too reckon we oughta…” Not able to get through a single coherent sentence, Apple Bloom couldn’t help but try and agree, Scootaloo also doing so by nodding her head rapidly. At the same time, they all started towards the door. They weren’t sprinting, but definitely hurrying, almost as if they were escaping the building with some forbidden tome or something like that. In stiff steps, the awkward trio speedily shuffled out of the bedroom and to the front door hoping they didn’t bump into Twilight on the way.

Upon opening the front door, shuffling out and calmly closing it behind them, they did the first thing that came to mind for them right now. Running. Running away. Running back to the clubhouse and hiding away, not letting anypony else see what exactly Sweetie Belle was still levitating and what exactly they were so curious about.

Dashing off, they kept the book close to them and made sure to hide it’s cover from those looking on thinking the crusaders were doing typical crusader things. But as they zoomed away, the three never even thought to check the room again, not having noticed the book titled ‘The Egghead’s Guide To Pony Reproduction’ set on the table behind the door.

“Quickly! Quickly!” With the other two not far behind, Scootaloo shoved their flanks with her hoof, pushing them inside quicker so she could slam the door instantly after. Having escaped the eyes of any and all onlookers, they had successfully vacated to the privacy of the CMC’s clubhouse. Here they wouldn’t be bothered and here they could put down the book without having to fear of anypony else getting to it.

Not minding the shoves to their rears, used to the roughhousing, Sweetie Belle and Apple Bloom felt their pent-up panic slowly fade away. It was tough being constantly on-edge, but now they could finally investigate this item they gotten more thoroughly.

After checking the coast was clear outside the windows, Scootaloo joined them as she too relaxed a little. As of a few seconds ago, their new book had just been plopped onto the floor, and with the three sat around it, they just stared at the object as if it were some foreign magical item that was to be feared.

“…So when’re we gunna open it?” Apple Bloom looked up at the others, and they shrugged. It had obviously been embarrassing for them to bring this back here, but now that they were in such a safe environment, able to… admire the image on the front, their curiosity was taking them over and rapidly building their impatience.

After a minute they were still doing nothing but looking at it, so out of a sudden anger at nopony having done anything, Apple Bloom leant forward, opening up the cover and revealing the first page to the trio.

…As it turned out, this book was going to have many more pictures in it than they’d expected. On the first page was the chapter title that just said ‘Chapter 1’, yet what made their eyes widen was the fact that it was accompanied with a huge veiny horsecock, a mare seductively looking into their souls as her tongue was stuck out, tasting the shaft.

The shock from earlier had settled since first finding out the topic this book covered, and now they were in such a safe environment for them, the three just got more interested, wanting to fulfil their bodies’ strange want to continue. But despite her body’s protests, Sweetie Belle was hesitant. “G-Girls are we even sure about this? We don’t even know exactly what c-cock worship is…”

Feeling the opposite way, Apple Bloom and Scootaloo both wanted to argue their points, the farmfilly going first. “But Sweetie’, this is a new chance to get our cutie marks. We ain’t never done this before and it… it does look kinda fun…”

“Yeah! And it was given to us by Twilight herself! We should do it!” Chipping in, the two were clearly enthusiastic about this, and it wasn’t just the feeling between their legs making them this way.

Thinking deeply, the white filly searched her mind. They didn’t even know what was making this look so… interesting, and knew so little about this topic anyways. But that’s what the book’s for… and they are making some good points. So with a heavy sigh, she reluctantly agreed. “…Fine.”

Slam.

With it closing, that noise being the only one in the clubhouse, they had finally finished reading the book. It had taken hours, so long that it was now dark out, but now the trio had a wide new array of knowledge to put to use. “That was…” Sweetie Belle spoke but couldn’t finish, Apple Bloom finishing her sentence for her.

“It certainly was somethin’.” The book had had much more in it than they’d have ever expected, and they really wanted to try it out.

Inside the tome had been a treasure trove of information, teachings on everything they could possibly have wanted to know and more: blowjobs, assjobs, regular intercourse, anal and a bunch more, it going into excruciating and elaborate detail about everything and them taking in all of it.

From before the clubhouse had been how it always had, a cozy little hut that felt childish and smelt of the nature surrounding it. Now it had changed. The hut was less cozy, a hot and arousing atmosphere consuming it. The place felt lewd and the smell stunk of three different and potent aromas, them coming from a few puddles on the floor under the mares.

With a sly grin on her face, Applebloom turned to her unicorn friend, smugness written all over her face. “Whaddya say now Sweetie Belle? You wanna try it?” Considering how much more she did now she was sure she knew the answer already.

“Y-Yeah…” And she had been correct. Looking off to the side with her blush, Sweetie’ definitely did want to try it out for some reason that she couldn’t quite put her hoof on. Without any of the girls noticing however, the answer to her question was right beneath them all. During reading, the trio of horny mares had started grinding against the smooth and polished floor, unknowingly rubbing their wet cunts and letting their unrecognised arousal sway their judgement as their juices spread.

This wasn’t all about cutie marks anymore. They obviously did still want them, but that felt like more of a bonus for when they got to do this too.

This’d be fun, they were all quite sure of that, but Sweetiebelle’s face once again showed some apprehension. “But… Uhh… Wouldn’t we actually need a stallion if we wanted to do this, girls?” Making a fair point, she doubted any male ponies would be entirely open if they were to just offer such an… embarrassing thing as this.

Fortunately for them though, Apple Bloom had a tiny lightbulb light up above her head, their mutual confusion turning into optimism. “Hey girls, ah got an idea!” With them turning to her, the yellow filly stood up dramatically, looking down on them as she boldly proclaimed “Big Mac’!”

Immediately upon hearing it, the pair’s faces showed they were considering it. It was a good idea, him definitely being a stallion and all, but Sweetie’ and Scootaloo were quick to point out the flaws in her impromptu plan. “Dontcha think we’d need to be… a-alone with the stallion to do this? Not with Granny Smith and Applejack in your guys’ house.” It was a rare sight to see the pegasus of the trio blushing and stuttering, but she still was.

“And…” The unicorn interjected. “How do you know that Big Mac’ will agree to that? Th-This kind of stuff does all seem a little… taboo.” When saying their thoughts they expected to just move onto thinking about anypony else they knew that had a dick, but the cocky smirk on AB’s face told them otherwise.

It was because she’d already prepared for them concerns. She knew they wouldn’t mind doing this with Big Mac specifically, so all clearing him as an option did was let their search end successfully and efficiently. Raising a hoof she listed of her answers. “Firstly, Granny an’ AJ have headed on out of Ponyville to Appleloosa for the weekend to help with… somethin’, I wasn’t listenin’ to that part. And secondly, yeah, Big Mac’ might not agree to this if we ask ‘im, but why ask when we could surprise ‘im? I know when he goes to bed, and I’m sure that if we do a good job with it then he won’t even wanna stop us!”

“Yeah! Let’s do it!” Scootaloo was in. There was no resistance or hesitation in her exclamation, only excitement and eagerness to try put this whole ‘cock-worship’ stuff. Sweetie Belle however…

“I’m not so sure guys… Isn’t it kinda bad to try this on him if he won’t want us to?” She absolutely wanted to try this out, some needy feeling in her body (but mostly between her legs) encouraging her to. Her conscience however was trying to point out that Big Mac would have little say in this, them just using him.

Scootaloo defended their new plan this time, her as enticed as Apple Bloom. “I mean, yeah, I guess. But this could finally get us our cutie marks! Plus, if the book is right then he’ll really enjoy it too.”

Sweetie Belle was still frowning, unsure of all of this and not wanting to do the wrong thing, but she’d follow these two to the ends of Equestria, so she cast aside her doubt, willing to at least give it a shot. The young mare really didn’t think she would be doing this, but deep down a part of her wanted to too, this all so… tempting. “…You two are annoyingly good at convincing me to do stuff.”

Smiles lighting up their faces, Scootaloo and Apple Bloom dived onto their friend giggling, attacking her with a group hug. With a high-pitched squeak, she fell back onto the floor, forced to as their weight was way too much for her to handle. Just like that the trio were back to normal, laughing and messing around without a care in the world.

Eventually though they had to calm down and prepare for their devious sneak-in tonight. Straightening themselves out and peering at the clock, they saw that they had about a couple of hours until Big Mac went to sleep though, meaning they had longer than that to wait for him to fall asleep.

“…You two wanna go over the book again?” Grinning at them, they soon shared the same enthusiasm as Apple Bloom.

“Yeah!” “Sure!”

Nighttime. The time to strike. Celestia’s sun had set and darkness covered not just Ponyville, but all of Equestria, giving three mares the perfect opportunity to stealthily shift from place to place (despite them not planning on doing much of it).

It wasn’t like any of them needed to sneak into the Apples’ house. They were already in there, in Apple Bloom’s bedroom pretending to who looked after them that they were having an innocent crusader sleepover. Nopony could’ve expected what the fillies were plotting in there though, their shenanigans vastly more sexual than usual.

“Okay girls, here’s the plan...” Whispering, Apple Bloom knew that Big Mac wasn’t far from them. The building did have thick walls, and she knew the whispering was a bit of an unnecessary precaution for the heavy-sleeper the stallion was, but it helped add to the ambiance of their daring caper. “We’re gonna tiptoe over to my brother’s room makin’ no noise. After that we sneak into his room, and then his sheets, getting to see a real life horsecock up close!” It was difficult withholding her excitement to keep it down, but she didn’t have to, she wanted to.

Firm nods coming from her best friends, Scootaloo was just as ready as she was, Sweetie Belle hesitant yet again but unwilling to stop them or bring it up. So on that, they silently opened Apple Bloom’s bedroom door, creeping out and into the darkness of the home’s halls whilst quietening their giggling.

The mares reached the door, the handle being twisted as they let themselves into where they shouldn’t be. Noiselessly, they then shut it behind them, leaving the four of them alone, just them and Big Mac. With the moonlight filtering in illuminating his figure, it wasn’t difficult to tell where he was or where they needed to be.

Apple Bloom’s brother was lying on his back on the big bed. He was utterly oblivious to when three ponies gently lifted up his bed sheets, crawling in carefully whilst checking for any signs of him waking. And finding none, they huddled together beneath the bedding.

As the three were getting comfortable, a little bit of light shone through the cloth they were under. It wasn’t much, but enough for them to see each other, and enough for their attention to lock onto the massive ballsack ahead of them.

Keeping their eyes on the pair of very real balls, it hit them. Apple Bloom and Scootaloo’s faces shone with the beaming smiles of finally being here, doing this. But of course Sweetie Belle’s was much more apprehensive. W-We really shouldn’t be… The thought of withdrawing was a very convincing one, but it stood no chance against what suddenly overwhelmed them. Under his sheets, Big Mac’s musk, his heavy masculine scent, invaded their nostrils. Most of it was coming from his testes and instantly the three fillies were hooked on it.

Taking deeper breaths in, letting that intoxicating and pungent smell fog up their minds, all of the trio moved closer. Sweetiebelle’s worries and concerns were now gone, nowhere to be seen as she was the first to make physical contact with the stallion. Pushing onward, her nose pressed up against the burgundy skin, the mare hypnotised by the aroma and how it was so deep, so commanding, and how it made her insides flutter. Soon, it was all she could smell, and she was fine with that, too drunk in it to care about much else besides the stench of the plump, cum-filled, bollocks of Big Mac.

She was leaking her juices onto the bed, but she wasn’t the only one with all of their own aroused smells clouding up the cramped area.

“H-His dick’s still in its sheath, right?” As quietly as she could, Scootaloo pointed out the obvious. Above the balls was nothing, just a bit of skin known as the sheath for the dick to come out of when aroused. “We need to arouse him. How do we do that?”

Despite being somewhere else right now, Sweetie Belle had heard her too, reluctantly removing her face from the warm skin. She chipped in her own idea, also whispering.“The book said the balls are an er- erog- er- erogen… Ugh! They make him feel good too!”

Glancing at each other, all crusaders had the same dirty idea as they smirked. They got as close to it as Sweetie’ had been and each took a couple of licks of the testicles, the sweaty taste not unpleasant as something above began happening. “I think it’s workin’!” The three mares dove back in, giving Big Mac’s huge balls what was basically a tongue-bath and enjoying it.

The feelings beneath them were getting quite uncomfortable. Their marehoods weren’t getting any stimulation, but once again their bodies began subconsciously grinding their dripping pussies on whatever was beneath them. It just added more fuel to the fire within them though.

And they weren’t the only ones getting turned-on.

Backing away from the two orbs, Scootaloo looked up in awe at Big Mac’s dick. The head revealed itself from the sheath, but after that it made its way out and created a huge tent from the bedcovers. Rising upwards, she got to see as it kept going, the hard veiny and girthy shaft looking more than imposing from this angle. “Oh my gosh! Oh my gosh! Oh my goooosh!” Failing to contain her excitement at the sight of the monster before her, Scootaloo was still whispering, but way too loud to be considered stealthy.

Apple Bloom heard the hushed exclamation, moving back to reprimand her. She stopped however then she too spotted the behemoth towering over them, equally awestruck by it. That thing’s huge! I-It looks even bigger than the ones we saw in the book! The impressive size brought arousal through the two, but it also brought up some concerns: Would we even be able to do ‘sex’ with that? It’s… Just the idea of trying to cram that all in her would be a bit of a challenge, but fortunately their dirty book had had a lot more in it than just regular sex advice.

“Hey Sweetie’, you can stay at the balls if you want. We’re gonna be checking out this though.” Scootaloo saw how much she was enjoying herself down there with her muzzle smushed into his sack, so let her stay. Her and AB had something else to check out though.

“Mmhmm!” With a muffled moan, the usually level-headed pony agreed. They could do whatever they wanted, but she’d be happy staying down here, licking, sucking, and worshiping his testes without stopping inhaling their strong smell.

Meanwhile, Apple Bloom and Scootaloo each mounted one of Big Mac’s muscular thighs. With the dark-red horsecock between them, they were aware of how they were grinding now, actively rubbing their vaginal juices into the big-dicked brothers’ fur, their bodies openly accepting the addicting pleasure and not letting them stop, only letting them quietly moan to themselves. They didn’t think it was fair that they were the only ones feeling good though, the poor throbbing beast of a cock in front of them not getting any of the stimulation it deserved.

When their eyes met, it was as if a telepathic message was passed between them. In tandem, the mares both moved their muzzles forward, going for different parts of his dick without getting in the way of each other. Scootaloo was at the head. She wanted to learn as much about the flared tip as possible, and began by introducing it to her eager tongue. At the top of his length, she was basically giving only his tip an incredibly inexperienced blowjob, but, further down, Apple Bloom tried taking care of the rest of the shaft, long licks up it sure to stimulate it as she went to town on it. Plus, they found it even tasted good too! A delightful bonus to make sure they wouldn’t stop.

With Sweetie Belle on the balls, Scootaloo on the tip, and Apple Bloom on the girthy middle, they had done it. In just a day the three had learned to worship horsecock, and were loving every second of it.

In life, Big Macintosh was not too different from your average stallion with his morning routine: he woke up every day, did his jobs or chores or whatever, and had a good night’s sleep at the end of the day. He did have other things in his life, but didn’t really need anything else other than his family.

In other words, he was happy with what he had, and considering he was aware of just how above-average his package was, he was okay with not wanting more.

For him, things rarely ever got in the way of his daily routine. Maybe the occasional threat of Equestria being destroyed would shake things up a little, but usually he got to go back to normalcy, nothing strange or out-of-the-ordinary happening to him in particular.

Today however (or tonight, I suppose) was different for the quiet stallion, some nightly visitors slowly waking him up from his slumber in the most peculiar yet most pleasurable way.

Urgh… Wh-What in tarnation? Awakening sluggishly, Big Mac slowly opened his eyes, whatever had woke him up still doing what it had been doing. What’s- Ngh! What’s happening? Down below his waist, he could feel how rock-hard his erection was, it fully-erect and as aroused as it could be, but something else was happening that was making it feel the best it ever had. H-Holy shit!

He didn’t know what was happening, but regardless he didn’t want it to stop. And it wasn’t just his dick, his balls and even his thighs were feeling too good, way too good. He had no clue who was under there or why they were doing this, but maybe he’d invite them out for drinks sometime after this. If they could do this to him more often then he wouldn’t be opposed in the slightest, in fact, it was physically difficult to stop himself from moaning out loud right now. No matter what though, he knew he’d enjoy this, and nothing would stop- “Ahn!”

The fuck? It was a moan, clearly, coming from under his blanket. He’d assumed a mare or mares were under there, doing a phenomenal job at pleasuring his dick for whatever reason, only the moan sounded like… A-Apple Bloom?

Moving upwards and feeling the obscured figures freezing in place, Big Mac sat up, leaning on a couple of pillows and staring at the shape under the blanket. Soon breaking himself out of his head though, his hooves touched the sheet, sliding it off of everypony there in a single movement.

What greeted him was three pairs of wide eyes, staring back at him like fillies caught with their hoof in the cookie jar, only they were caught sucking his cock and balls instead. Like this he was stuck staring at them, barely registering when they started moving again or when they looked at each other as if to confirm this was really happening. It’s safe to say that he’s confused. What the fu-

“Well hey Big Mac’!” Smiling innocently at him, from her face you wouldn’t’ve been able to tell she’d been doing the dirty deeds she had been. Apple Bloom’s face being inches from his cock though, the shaft smeared in her saliva did give it away. Besides her was Scootaloo who looked impatient, her eyes darting back and forth from his meat telling him that she wanted to go back to what she’d been doing. And behind her was Sweetie Belle, not seeming to care much that he’d woken up with her half-lidded eyes looking back at him and her muzzle nestled in his junk. Plus Big Mac was pretty sure she was touching herself with her hoof tucked under her like that.

“A-A-Apple Bloom! Wh-What in tarnation are you three doin’?” He was baffled. Just the thought of somepony sneaking onto the farm and into his room to get him off was crazy enough, but his little sister and her friends?

The filly wasn’t phased though, the other two not seeming to care much either. “What’s wrong Big Mac’? We just wanted to come help you out with this thing.” Lightly gesturing to his dick, her nonchalance was just confusing him more.

“Wh-What? A-Apple Bloom, we can’t be doin’ this sort o’ thing, we’re- AAAHH!” Trying to stop her, Macintosh was cut off by himself, moaning deeply.

Unexpectedly, Apple Bloom had taken a long experimental lick up his shaft, a surge of pleasure shooting through him because of it. It felt amazing, and considering he hasn’t had a mare even touch anything down there for years made it all so much more pleasurable. “Aw c’mon Big Mac’, d’ya really want us to stop? You look like your havin’ a good time too!”

He daren’t think the smirk on her face or the tone of her voice was seductive, but he couldn’t deny how his body yearned for more pleasure that she and the others could bring. So instead of responding, Big Mac was stuck, frozen in place without giving an answer. His body refused to let him deny her advances, but it wasn’t like he could tell his little sister to do more, so he didn’t move, panting as she watched his ashamed face.

Moments passed of silence in the room. Nopony uttered a word, not until Apple Bloom broke out of her idea-filled thoughts, exclaiming elatedly to them all. “I got an idea!” With an excited grin, her head snapped to her two comrades.

They were both still wanting to get back to what they’d come here to do: worship, but they humoured her, their eyes lazily glancing over without their heads moving.

And what they saw was her smiling devilishly back at them, waiting to enlighten them with her masterful plan. “Girls, two words: double assjob.” That got their attention. Holy shit did it. Instantly their bodies perked up, them not just excited but awestruck by the proposition.

They knew plenty about the sexual act, in fact, that chapter in the book was one of their favourites, so it was no wonder they dove on the opportunity Applebloom presented to them. “Yeah! Let’s do it!” As rambunctious as ever, Scootaloo made her joy known, and Sweetiebelle even removed her face off Big Mac’s big balls, but only because she’d been promised something better.

Rising to her hooves, Sweetie’ climbed atop the stallion’s thigh were Apple Bloom had been before she’d moved onto his belly. Aroused, her and Scootaloo looked at each other before twisting their bodies and letting their rumps face the fat phallus between them.

Compared to fully-grown mares, the Cutie Mark Crusaders’ asses may have been considered smaller-than-average, but they actually weren’t, especially in comparison to their currently petite bodies. So actually they’re big, they’re round, they’re bouncy, and they’re the perfect cushions to sandwich Big Mac’s dick between.

Speaking of the randy red pony, he watched every movement they made. Not once did he try to stop them though, instead his body just prepared for the pleasure it was waiting to get, not letting him think an innocent thought as they proceeded.

Meanwhile, Apple Bloom just kept watching the three of them. Sat atop her bro’s belly, she was willing to wait her turn… for a little bit longer anyway. For now she’d just keep grinding on his fur and letting her aromatic juices sink into it.

Sweetie Belle and Scoot’, both under watchful eyes, exhaled hotly one last time, right before they pushed their asses back onto the horsecock behind them in sync with each other. Smushed onto his shaft, their chubby cheeks encircled an area of it. Some of their behinds were pressed against each others, their butts trapping the meat between them. But hey hardly noticed their asscheeks squished against the others’, not when their wet marehoods felt even better rubbing on the hot skin of his girth than any bedsheets or thighs could make them feel.

Without saying a word to each other, the pair managed to start grinding at the same time. It was messy with their asses trying their best yet still being unsynchronised, one of the two going up while the other went down. Big Mac’s cock got pushed around a little, the amateurs still learning and being very eager to learn through experience, so it made sense that the two soon got the hang of it and were giving him something on par with a professional assjob.

At the same time as the other, Scootaloo and Sweetie Belle thrust their bubbly tushes back. It felt incredible for their stalllion, his dick being jacked off slowly, sensually, and in an insanely erotic way, but at the same time the movements were grinding their dripping folds all over his shaft. He wasn’t the only one being pleasured here, and everypony could tell from the girly moans that the pair of fillies working his shaft weren’t even trying to hide. Every backwards hump sent pleasure through Big Mac’s muscular body, but as well as that they shot jolts through the young mares’ bodies, and nopony wanted them to stop as all their orgasms building up.

“Mmmph! You feelin’ good there Mac’?” Grinding hard on the stallion’s ripped front, Apple Bloom turned to her brother’s face, it giving her the answer she wanted as he grunted loudly, him having given up resisting and subtly thrusting up into the amazing asses pleasing him. …It seems like everypony’s havin’ a good time here… If anything, Apple Bloom was starting to feel a little left out, but fortunately she’d studied every page of that kinky book and knew just how to include herself more. Reluctantly stopping her grinding, the mare walked up to Big Mac’s face. Grinning down at the helpless stallion, she spun around and dropped her ass onto his muzzle, resuming her grinding with his face trapped between her cheeks. I’m sure Mac won’t mind if I- “Ngah!” But it seemed her brother was caught up in the lust of it all too, and she instantly understood that when his tongue shot into her, toying with her insides, eating her out. “Ah! O-Oh gosh! D-D- Ahn! Don’t stop, Big Mac’!” This is the best!

Though he wouldn’t admit it, Big mac was loving getting to taste the juices pouring out of his sister’s snatch, and it wasn’t long before the hunky stallion’s muffled voice moaned out to those making him feel so good. “Ngh! I-I’m gettin’ c-close! Agh!” The room was filled with the sound of everypony moaning, and the smell of the arousal was everywhere. All four were endlessly bombarded with the endlessly arousing mix of three sweet, intoxicating fragrances, and a heavy musky one that the small trio couldn’t get enough of. In other words, all of them were lost in their lust, and nothing would stop them now, especially not themselves.

“S-Something’s happening!” “I… I feel it too!” The pulsating member was glistening in the moonlight, it slick with not just vaginal juices but precum as well. It throbbed more and more as the pair of ponies sped up. With just a few more desperate pushes back, they were nearing their climaxes, not just the two giving the assjob, but Big Mac and Apple Bloom as well.

Faster and faster. All of them were this close to cumming with their constant rapid movements, until a deep moan signalled the end. “Hngh! I’m gonna- All it took was a few more frantic thrusts upwards, until finally, Big Mac came. With the crusaders still making love to the girth and him groaning in ecstasy, the first rope of cum shot out of his tip and up into the air. Thick, large and very fertile, the glob descended back down, landing on Scootaloo’s back. But his balls weren’t nearly finished.

Load after load emptied out of him, each one as big as the last. Splurting violently, it had been building up for a while, and now Big Mac got to be relieved of his blue balls as all the hot stallion jizz stored up either landed on him, on his bed, or on the seductresses who made him cum in the first place.

But for them, whether it was the sight, the smell, or the feeling of it on their fur, with two of three crusaders covered in cum their first ever orgasms shook their body. A chorus of gleeful cries filled the room, their backs arching as they came, squirting either onto his dick or into his mouth.

All four felt the best they’d ever felt, and soon after Big Mac’s ferocious bucking and their high-pitched moaning ended, their orgasms ended too, and they all collapsed.

On Big Mac, on the bed, the Cutie Mark Crusaders panted desperately after the exhausting activity, but they didn’t regret it one bit. “…Golly, Big Mac… That… That was…” It was indescribable, truly, but as she laid on his burly chest, she couldn’t help but notice something that took her mind off the thrilling feeling now leaving her body.

Between Sweetie Belle and Scootaloo, his dick (it a little covered in its own cum) was still erect, hard, throbbing, and clearly waiting for more. One round wouldn’t satiate that beast he had, and that thought made Apple Bloom’s pussy get even wetter than it was already. She didn’t have to think anymore, only acting on her body’s urges.

Whilst the rest regained their energy, the yellow earth pony rose to her hooves, and confidently, she strode over to the erection. It took walking through some jizz, but it was instantly worth it when the dribbling tip became only inches from her mouth. It stinks so good! Quickly glancing back at the unaware stallion, she smirked, before she made her move and wrapped her body around the sweaty, slick shaft that was over half the size of her. Apple Bloom had to slide Scootaloo to one side to get here, but she knew she wouldn’t mind.

“Ngh!” Glancing down at her with his energy fully replenished (him having much more stamina than the small mares) Big Mac spotted her on his thigh yet again, hugging his dick with her front legs, it going up to her upper chest. Neither had to say a word for him to understand what her devious smirk said: ‘We’re not done yet. The others might need a little more rest but we both want more and are going to get it.’

That was what her mischievous face said to him, but as he kept watching her and not saying a word to stop her, she did decide to speak up. “Ya ready fer round 2, big guy?”

He didn’t get the chance to ashamedly admit that he was ready, not before she took one long lick of his flared head, once again shooting pleasure through him whilst keeping constant eye contact. And luckily for her, it also granted her the opportunity to taste Big Mac’s seed, Apple Bloom even more aroused by the tasty glob she’d slurped up.

By now, her juices were practically pouring out of her, and Bloom was tired of the foreplay.

Inside of the book, there were chapters upon chapters of things to do to pleasure a stallion’s horsecock and submit to it, but throughout every page, one thing kept being brought up: sex. Now, despite what some stereotypes may say, this farmfilly is actually pretty smart, so very quickly she had been able to put together exactly what this ‘sex’ was, as well as understanding just how unfathomably good it was supposed to feel with some stallion as ‘gifted’ as Big Mac.

Basically, Apple Bloom wanted to try it, and she was going to.

Sweetie Belle and Scootaloo were finally regaining their strength, so Apple Bloom didn’t have to do much to coerce them off her brother and back onto the bottom of the bed where they first laid eyes on his huge, dark-red testicles.

After that, the yellow pony clambered back up onto her brother’s belly, ignoring the semen sinking into her fur and staring her brother down seductively for the millionth time today. “So Mac’, how about we do a little more than an assjob…” Backing her rear into his cock and letting it rest between her cheeks, she continued convincing him with her erotic and alluring voice. “Don’t you want some place hot and wet to dump another huge load?” When speaking, she moved her ass up and down, stroking him with it teasingly. If he’d gone even slightly flaccid after cumming once, then he sure as Celestia wasn’t anymore. Meanwhile, Apple Bloom kept up the tantalising taunts as she watched his will break. “All you have to do is ask and I’ll let you have your way with me, wouldn’t you like to-“

The problem with her plan however, was that she thought she had full control over the virile stallion, while in fact, she was truly at his mercy.

In an instant, the mare was cut off, but it was only because his strong front legs moving like lightning, and wrapping around her back firmly, holding the mare in place on top of him.

Another assumption Apple Bloom made was that she would have to whittle away at his will more, her somehow entirely unaware of how Big Mac had stopped listening to rational thought long ago. Right now the only thing controlling him were the carnal desires flooding through his body, that and his lust-riddled mind being what was trapping his sister in place.

“Uh… Big Mac? Y-You okay there?” In seconds, all of the power she held over him vanished, and she realised just who was in control now, that hungry look on his face telling her how this was going to go down. He’s not going to hold back, is he? She didn’t know whether to be terrified or turned on.

With one leg still holding Apple Bloom in place, Macintosh reached his other leg down past her. Hungrily, it wrapped around his length, and once the stallion grabbed it well enough, he pulled it down ‘til the tip was pressed against Apple Bloom’s entrance. And so, he began pushing himself against the pony’s pussy lips, not exactly being gentle with her and grunting needily as he did.

However, despite her previous enthusiasm, Apple Bloom tensed up when realising how big the flared head felt entering her puffy snatch. “Ah! B-Big Mac, are you sure that thing’ll fit? I-I don’t think it’s gunna- NGAAAH!” She didn’t get to finish, all she could do was give in, helplessly accept the role reversal she was forced into, and feel his hung horsecock prying open her walls and slipping his tip in. Th-That thing’s breaking me!

In a single movement, he had shoved just the head into her wet cunt, and already Apple Bloom was feeling like she was being ripped in two, especially when he forced through her hymen. It was an equal mix of pain and pleasure, but clearly Big Mac wouldn’t stop here.

Having literally no chance of escaping his burly legs’ grasp, Apple Bloom wanted to try and accommodate his gigantic girth, but with every slight push he stretched her tight virgin pussy to it’s limits. “AAHHN! S-Slow down Mac’!”

Rubbing their own marehood’s with their hooves, Scootaloo and Sweetie Belle watched on in awe as her big brother didn’t show any signs of slowing. He just kept stuffing her full of his meat, widening her cavern and deeply moaning, right up until-

“NNGGAAHH!” Apple Bloom’s eyes rolled up and her tongue stuck out, right as her sibling’s huge cock reached the deepest part of her vagina. She’d only orgasmed once before, all over his face, but that one paled in comparison to this. Her entire body shook with pleasure, the pain entirely forgotten about as the small mare came, hard, juices spurting out of her pussy with power behind them.

But the pleasure didn’t stop there. After watching his sister cum (it arousing him unendingly) Big Mac pulled back from her womb. He hadn’t been able to fit it all inside her, just over half of him fitting in, but the stallion didn’t care, her tightness squeezing down on his veiny cock more than made up for it.

Again, his dick rubbed against her lubricated insides as he pulled out, it hitting every spot she had. He wouldn’t let the orgasm still racking her body end.

When only his fat head was left in, it took not even seconds for him to start craving being inside her again, so after he planted his hooves firmly on the bed, he began shoving himself back in once more.

To Apple Bloom, this experience was (expectedly) unlike anything she’d ever experienced before. She’d never felt anything even half as good as this, ever, which was probably why she could barely make out any words. As he thrust into her for the second time, the noises that came out of her mouth were usually either adorable squeaks when he hit her g-spot or throaty moans of pure ecstasy. By now she’d collapsed on his chest, her body flat on him and refusing to move, willing to be used by his beastly horsecock.

Continuing his push in, Big Mac felt himself press against her womb again, so, eagerly, he quickly pulled out again. And after that he went in, and out, and in, and out. With each push and pull it got easier, her hole providing plenty of its own lubricant so they could both get to feel more. Over a short amount of time, the stallion was getting faster, and more frantic. In a matter of minutes, his thrusts into her were going just as deep, but he no longer needed to push past her defences. She was still incredibly tight, but her body needed his too as it welcomed the immense intruder, and very quickly he was jackhammering her powerless pony pussy.

“AH! NGAH! F-FUCK! MORE! AAHN!” Over and over and over, he used her small body like it was a toy. The constant erotic squelching was all that could be heard besides the begging moans of the two, with his hectic humps slamming his huge cock in and out at a rapid speed. His huge balls were flying as he let loose on her, and she was showing her appreciation to him, screaming it out for the empty farm and her two best friends to hear.

But after the nonstop pleasure being sent through their bodies (and Apple Bloom having cum to her brother’s cock countless times) Big Mac was finally getting close to cumming again, having another healthy, fertile load to shoot out, this time doing it into somepony.

He never told them anything about his imminent climax, but his slams had become more desperate and his moans even louder. So after bombarding her with his undying and passionate lust, his legs moved off her and his hooves grabbed her body. Big Mac thrusting madly one last time, she was shoved as far down onto his cock as she could go, and with her still failing to cover all of his length, he exploded inside of her.

The ejaculation was just as potent as the one earlier, only Sweetie Belle and Scootaloo didn’t get to see and experience this one. All the two saw was the penis-shaped bump in Bloom’s body, that and her belly growing little by little, the cum filling her insides making it expand from the sheer quantity of spunk.

Splurt! Splurt! Splurt!

The incestuous pair had the orgasms of a lifetime, them screaming to prove it to the other ponies. And for Apple Bloom, white filled her womb, white filled the tiny parts of her cavern that he wasn’t filling, and white spilled out of her and dripped down his shaft onto his brilliant balls that produced it all.

Pulling out of his sister one last time, Macintosh’s erection sprung up until it pointed the ceiling again, but the other crusaders’ eyes weren’t on that. Apple Bloom collapsed onto his front when he unsheathed himself from her, and with him out, a tidal wave of cum spurted from her when her big belly hit his. It shot out at such force that some even hit the unicorn and pegasus, and instantly, her friends ran over to the little mare to check up on her.

But they didn’t have to say a word to understand exactly how she was feeling.

Lying there, napping, she was recovering from such a mind-boggling climax, wearing the biggest delirious and pleased smile on her face while the cum trickled out of her and into Big Mac’s fur, making its way onto his now cum-covered bed.

A beat passed, and that was app that was needed for the two to recognise exactly what they wanted.

At the speed of light, they shot over to between the male’s legs so he could see them perfectly. With one on each side of the massive member that refused to go down, they posed, presenting themselves and giving him the perfect view of both their equally tight virgin pussies, their tails lifting in tandem.

“My turn’s next!”

“No, it’s my turn!”

“But I want it most!”

“And I need it most!”

Big Mac was in for a long night and probably wouldn’t be getting any sleep, but at least he had the stamina to keep up with the rowdy, energetic cock-worshipers. But who to choose first?

Fortunately, despite it being a life-changing experience for the three, the amorous night never had any consequences for any of them, especially not the next day at school.

“Okay everypony, as you’ve all reached the age of consent recently, we’ll be learning about sex today. Does any of you already know anything about this topic?”

Enthusiastically, three eager hooves shot up.

…Definitely. No consequences whatsoever.

Author's Note

I’m happy with this one, I think I wrote it well!

I think I’m going to try focusing on writing one thing at a time from now on (sometimes) so I can actually get some fics done, whether it’s a one-shot, a sequel, or even just a chapter for a story.
I have a massive collection of one-shot ideas stored up somewhere so I might go through them while I do that.

Enjoy!
