3332678 Well, let me think, ummmmmmm...................................... how about a pony that was raped, and how she worked her way through, being called names and stuff, and soon she ends up finding a lover, that loves her?

Social Climbing; or the Heights of Princessly Pleasure
Tags: comedy, sex
Characters: Celestia, Luna, Royal Guards, Big Mac

Though they're immortal goddesses, the eldest alicorns still have needs. Unlike Cadence and Twilight however, the sisters face challenges beyond finding the right pony...

They're too tall.

Sure, they could try other positions, stools for their partner to stand on, magic to hold them up... but sometimes, a Princess just wants to be mounted from behind without aids, like nature intended!

Possible resolutions: They shrink themselves. They grow their partner. They hook up with a pegasus. They actually find a pony who's tall enough. They hook up with a minotaur or dragon.

This can be used for either princess or both; it could go into graphic detail of their quest to get off or hint at it; it could even be a conversation between the princesses as they compare notes and share tips.

3333512 Her Majesty's Secret Service solves this by having Celestia use a temporary growth (whole body, not just there) spell on Night Light so that he's the same hight and size as her.

This could be a really funny Idea.

"Let us ask Cadance for her thoughts on the matter," Luna suggested.

"You know, Cadance has always been pretty small. I think Shining Armor can actually reach," her sister replied.

Well, what about horror movies? What if someone made a fic and posted ponified versions of movies like Carrie, The Exorcist, The Shining, and American Werewolf in London? Not sure where I would post this idea. but I guess here because some of these movies have explicit content.

Has this been done? I don't actually read much clop.

'Day' and 'Night' were Allegorical (they represent their naughty bits)
Tags: Romance (well, sex anyway)
Characters: Celestia, Luna

According to the legend, Luna became Nightmare Moon and was banished because "as time went on, the younger sister became resentful. The ponies relished and played in the day her elder sister brought forth, but shunned and slept through her beautiful night."

The thing is... Twilight was reading that out of a foal's book of myths and not, you know... an actual history book. Everything was sanitized and cleaned up so that parents wouldn't have to explain uncomfortable things to their kids.

What really happened was that Celestia was snapping up all the hot young studs (and mares. and drakes. and griffons. and minotaurs. and...), and Luna was sick & tired of getting sloppy seconds.

Eternal night? City-wide orgy.

Bittersweet Discolight concept.

Because she is a virgin, there is an entire realm of magic that Twilight cannot viscerally comprehend. She goes to Cadance for advice and is basically told she needs to get laid.

The thing is that as a Princess, Twilight has to be circumspect in who she sleeps with. Most ponies would assume that a Princess showing interest in them would love them, or at least like them, and particularly the Princess of Friendship. So most ponies would assume an emotion that isn't there, and she'd be using them. This goes especially hard for ponies who she might actually care about that way -- she's much more interested in human Flash Sentry than pony Flash Sentry, but she's kinda attracted to pony Flash Sentry... which is exactly why she can't ask him. If she uses him to learn about sex for purposes of her magical research, she'll ruin any hope she might have of someday developing something real with him. And she'll hurt him emotionally, which she doesn't want to do to anyone.

Ideally she'd want anonymous no-strings sex, but she's a frickin' alicorn, and she doesn't trust any disguise spells to hold up during sex because she has no idea what kind of stress sex might put on her magic, given that she's never had it. There is no pony in Equestria she can turn to for the no-strings, purely for educational purposes, experience she's looking for. Even guys who claim to offer that might be seeking to use her for her political or magical power, and be trying to parlay a sexual experience into something more for that reason.

So she asks Discord. Because she knows Discord does casual sex, and has happened to mention having had quite a lot of it over the centuries, especially while ruling equestria. And she figures that if Discord was going to get emotionally attached to anyone it would be Fluttershy, not herself. And while he'll make fun of her most likely, he won't try to use her -- he's already of equivalent rank and has nothing to gain, and he'll know there's no emotions in it, and he'll be okay with that.

The problem is that since the time when he did a lot of casual screwing around, Discord has discovered the value of friendship, and while he does have strong feelings for Fluttershy, he's also kind of obsessed with Twilight. He'll take the deal, knowing the extent of what's being offered, and what isn't, because he knows it's the most he'll get from Twilight, but it's going to tear him up inside because he actually wanted more... and he won't dare admit that to Twilight because that would make him look weak, and because he knows she doesn't feel the same way.

Erotica Creative Writing Class

Probably circa Season Two era.

Okay, so Twilight secretly writes raunchy stories involving her favorite fictional characters and/or historical figures, but hides them so that no one will know. Well, one day Spike accidentally thinks one of her drafts is a friendship report (he most likely didn't read more than a couple sentences) and sends it off to Celestia...

Who sends it back with critique and copyedits! Furthermore, seeing Twilight's interest in more,,, Er,,, Mature fiction, 'Tia decides to form a small creative writing class at Canterlot U that focuses on erotica. Intentionally bad PR0N, awkwardsauce, and lulz ensue. We should never read the texts ourselves, the entertainment should come from everyponies reactions to the works.

A short list of members:

Octavia: Writes mostly dull but heartwarming fluff. Rather tame, with married couples. The most extreme is pregnancy sex.

Twilight: Previously mentioned as being hilariously bad (things like actual measurements mentioned in text, awkward dialogue, and anatomical implausabilities), basically, if it's a common complaint about bad porn fics, she's an offender.

Fluttershy: ...The dirtiest stuff there. The filthier and more "Out There" the better. Torture porn? Wrote it. Rape and Stockholm Syndrome? Common. Scat? Judging by everyone's reactions, yes.

Rarity: Mostly there because she wants to read everyponies submissions. Has a liking for bodice-ripper, harlequin novel tripe, usually between nobility and The Help. Lady Chatterly stuff.

Fleur de Lis: No one can tell whether or not she's writing her own history with the names changed.

Celestia: The professor. Has a whole wing of her personal library of material (in my creative writing classes, the professor had us start out by reading professional, published stories), some of it even stuff she herself wrote.

Soarin: Embarrassed to be the only guy, but surprisingly writes the best stuff, finding the right balance of sex and sensitivity, without turning the characters (especially the mares) into sex toys.

Here's an old idea from back in the first season. I'll be including all the discussion from the thread I mentioned it in, for more inspiration:

Whore Mac and Pimp AJ

An idea that I thought would be a hilarious comedy.

Sweet Apple Acers is in financial straights. They aren't at risk of going into bankruptcy anytime soon, they're making ends meet, but the thing is that they are only making ends meet, with little in the way of wiggle room in terms of liquid assts. A bad season or two away and the farm will be in serious trouble. Applejack and Big Mac are up late one night going over the numbers trying to think of ways they could help fix the issue (what could be cut, what new money-saving farming techniques could they try, etc) but the only way that they can see how they could make more money is to open a side business, which for many reasons is not a valid option.

Still, Big Mac does have one idea that might work. Given the demographic ratios of single to paired mares in Ponyville and the surrounding areas, the best way for Sweet Apple Acres to increase revenue would be to open a side business where Big Mac hires himself out as a 'stallion escort,' with Applejack as his 'agent.'

Obviously, AJ is against whoring out her brother to every nag, mare an' filly in ponyville, but for the sake of the story she agrees.

I see this as a collection of one shots mostly. The first covering how they get through the red tape, what with zoning, licenses and registering Big Mac as an escort. Things like vaccines, health screenings... Measurements...

The rest of the one shots would cover Applejack and Big Mac both adjusting to their new jobs, with AJ having more than a few awkward moments when she recognizes some of their costumers ("A'ight, so y'all want the escort t' meet ya at yer place of residence? Okay, jus' give me yer address.... Okay, 66 Daisy-Star Aven- ...Wait.... Twilight is that you?!"), and when she walks by the old shed they're using for the 'on site services' to check on her brother, she learns more things about her friends than she'd be comfotable with ("Now what do you say?" "Yes ma'am." *CRACK!* "AH! Ah mean! Yes Mistress Fluttershy!").

And you know Celestia won't resist getting involved.

And of course there's fun to be had in keeping it all a secret from Granny Smith (who they think wouldn't approve) and Applebloom (turns out, Granny DOES approve, 'How else d'ja think I met yer gandpappy?').

And of course, there'd be room for drama with AJ trying to both be a businessmare, and still keep from seeing her brother as just a commodity.

I will admit right now: This was inspired in part due to the fic Big Daddy Mac on ED

Big Mac walked over to the counter he and 'Jack built on the back wall, intending to pour some cider for him and his current client, a white, pink maned earth pony mare with three little happy-faced yellow suns as her cutie mark. The stallion thought that was an odd mark for a lawyer from Canterlot, but maybe it was harder for talents to translate directly to careers in the big city, and she used her talent as a hobby? Maybe he could bring it up in the afterglow. He liked listening to folks, even though he didn't always speak himself.

At any rate, a little alcohol in the system right at the start eased any tensions the ladies may have, and gave him a little more excitement at the next few hours. Liquid Courage indeed.

"C'n Ah pour you a drink miss? Ah've got some apple cider an' wine, or if yer more for something not so strong Ah got-"

He was interrupted by a dull roar and a flash of light behind him. Turning around, the stallion was struck dumb by what he saw, his jaw practically on the floor.

Gone was the little lady from Canterlot. In her place was a mare of much, much larger stature. The three happy little sun cutie mark was gone, replaced by what would be better described as a portrait of the sun, that seemed to radiate with its own power. The now not-so-little earth pony had grown white wings and unicorn horn, and her pink mane had transmuted into long, flowing locks that shown with the colors of the rainbow, and moved on winds felt only by herself.

Princess Celestia leaned her head down to his eye-level, eyes set in an expression he had seen dozens of times by now.

"Good evening Mr. Apple. I have heard such wonderful things about you."

THREE WEEKS LATER​

"Big Mac! Big Mac! AH got great news! We got that merchant's deal in Canterlot! That lawyer pony kept 'er word!"

(from behind the door)
"Cherries. Oh, I love cherries! Those look super yummy! Oh... more strawberries. And whipped cream! More whipped cream! Now a bit of salt - but just a pinch! Perfect! That's perfect! Now for some - oh, oh that's good! Hot, sticky chocolate... Yes! YES! YES! Right there! Right there!"

(Applejack peeks into the room)
AJ: "What the hay...?" :wtf:

(Cue Pinkie Pie and Big Mac eating strudel at a table)
AJ: "...huh." (ducks back out) :eek:

Pinkie Pie (finishes her pastry) "Now for some more whipped cream!" :)

Big Mac: (looks around) "But... we're out of food...?" :confused:

Pinkie Pie (leans in and grins) :D

FALLOUT: NEW VEGAS x MLP:FIM Crossover Idea
I'm posting this in Mature just to be safe, but you can wright it Teen if you want

The Basice idea is it takes place in a Fallout:AU that had MLP:FiM as a populer TV show pre-war, Courier 6 (ether familer with this show or ignorant of it) stumbles apon a hunting party of a never before seen type of F.E.V. Mutants model after familer faces.

Hunting party consists of a maximum of 6, to a minimum of just Twilight and her pet Fire Geko yuongling Spike
the ponys dont look exactly like the show, they are mutated in some maner, I suggest ChanglingMane6 becouse the changling look fits the Fallout setting, but feel free to be creative. The Ponys (or whatever they end up getting callled) dont have magic, but do have powers (flight and telekinesis is a must, maybe short range teleportation and temporary invisibility too)

A language barrier seperats them, but eventually it is disided that atleast Twilight and Spike will join Courier 6, to earn recanition of there people from the Human, and maybe discover their origins.

[optional] Spike is a varient FireGeko with green eyes, spines and underbelley that breaths plasma fire

[optional] Twi and Spike ware dog callers(too ware around human settelments or something Twi picked up on her own before meeting Courier 6), Spike's says spike but Twilights says Sparky, witch sticks as a nickname (I realy want to read a fic with Twilight Sparkel called Sparky, Sparky & Spike)

My Mental Choices Are Completely Interfering With My Idyllic Ponyville Lifestyle

So there's this anime series which just reached the States. Right over here, for those who might be seeking shorthand. But before you head over...

Here's the premise: your typical high school student (Kanade) is under a bit of an unknown-origins curse. It's called Absolute Choice, and it's pretty simple. At random-but-generally-horrific points in his life, a rather sadistic universe will offer him a pick of two options. A voice will ring out, every word in his vicinity will twist to spell out the choices between presented. (Naturally, no one else can see or hear this.) And he must pick one. If he stalls, he starts to suffer excruciating pain, and it's implied that to deny for too long could be fatal.

There are rules, of course. They work like this:

1. You can't talk to anyone about the curse unless they already know of it.
2. The Choices bend reality. It doesn't matter how ridiculous or nonsensical a Choice may be: if it states 'the universe does this to you', the universe is going to do exactly that.
3. After you pick a Choice, if it's something you do, you must perform the option as worded.
4. If the Choice directly affects another party's actions -- a 'Who would you like to hit you?' thing, perhaps -- they will not remember the events afterwards unless the Choice specifically says they will. (The cursed will be notified of such exceptions before they occur.) If the Choice targets what you do, everyone's going to remember it, period.
5. The Choices are Sadistic. It's just about impossible for anything good to come from one. If a Choice looks positive, there's probably a catch, and it's going to be a nasty one. (Series example: at one point, Kanade is offered to either have his own harem or experience pure pleasure. He goes with #1 -- too late to realize the 'harem' didn't specify gender and he is now being chased by males. The stinger at the end of the episode reveals #2 would have been a dream of absolute bliss -- in the center of a coma.) Who would you like to embarrass yourself in front of? What humiliating act shall you conduct in full view of the class? That abandoned pornographic magazine you just found: smell it or lick it? You know that girl with the really defensive non-boyfriends? How many are going to attack you after this next Choice? How many are there?
6. There's no reliable Choice schedule. Hours can pass between them. Days. Seconds.
7, It's possible to escape the curse, but doing so means completing a series of tasks sent to you by a supernatural entity who's only slightly less of a sadist than whatever's inflicting the Choices. Fail any single one and the Curse is forever. Anyone who got out of it before can't remember exactly how it was done and won't be able to help you much. The universe will provide a supernatural companion for the escape attempt time, but the value of this assistant is dubious at best. And the Choices will continue during the tasks -- doing their best to get in the way. (Beating a task means any Choice in play at that time is wiped off the map, so at least you know you're making progress.)
8. The Choices will never directly get you killed. However, they will put you into situations where it's possible to die.

Our high school student has had his life, reputation, and hopes for sanity destroyed by the Choices. The tasks are just about as bad. (This being a sadistic high school harem comedy sort of anime, a Choice might be telling a girl to grab you and the task will wind up being 'see her panties. While they're being worn'.) But look under the surface, and there's subtext about the loss of free will and life itself as the no-win scenario -- within a whole lot of sadistic comedy with major harem aspects.

So.

You know all those Comments-Driven Stories we occasionally get passing through the various columns...?

*sadistic smile*

First Choice: which pony is this gonna happen to?

As a story concept, there are a lot of ways to go with it. I think it's a genuine chance to get Dark and Comedy on the same work (although too much of the former could derail the whole thing). The Choices could be offered to the readers, and then you continue the story with the one they picked. Or you make your own road and, as with the show, occasionally throw in a short bonus scene revealing how things would have gone if the main character went the other way. Mixing it up is also possible.

(The harem portion is optional, but may do a lot for saving the Comedy aspects: remember, 'you are a cosmic puppet in the hands of an omnipotent jerk' isn't easy to keep light.)

It's a new kind of Choose Your Own Adventure. Or in this case, Pick Your Own Disaster. Who wants to script it?

Y'know, this would explain a lot of Ponyville activity...

Fifty Shades of Blue
Tags: Romance, Sex (depends on how explicit you want to get)
Characters: Blueblood, Rarity (possibly), Harshwhinny (possibly)

Set Up: Blueblood has a powerplay fetish. The thing is though, he likes being the one dominated. In his daily life he's got wealth, connections and influence, charm, and is only answerable to the Princesses themselves or a large angry mob. The idea of being told what to do, that he's done something wrong... that he'll be punished for misbehaving... why, just the thought of it sends a tingle through his horn.

Normally he's very discreet about it, but after last year's Gala (six hours of small talk, the exact same same song played the entire night, and a total lack of champagne due to a shipping error) he felt that the risk of exposure would be worth even the slightest possibility of making the Gala tolerable. He made arrangements with a certain club he frequents to have a "date" for the evening... a mare of high standards, who would fit in at an event like the Gala, but also keep him in line. Due to his history with the club, he trusted them completely to make the choice and arranged to be surprised by who they picked over by the rose bushes once he arrived.

Keeping the rose, taking the last cushion, all of it was Blueblood trying to flirt with Rarity. He kept expecting her to put her hoof down and... well, not do something there in the middle of the Gala, but at least murmur threats and promises for later in the evening.

The morning after, when he got in touch with the club to find out what happened (She started off slow, and I know we were in public, but the way she tore into me at the end... by my sweet Aunt's fanny, I'd love to have a session with her again! How soon can I get on her calendar?) left him unspeakably mortified to find out that she was a total stranger.

Plot: There's a few options on where to go with this... rehash the Gala, from his point of view is an obvious one.

You could have him discreetly meet with her to explain himself, and maybe confess that he can't get that final vision of her, furious and beautiful, out of his mind. (A fine opportunity to segue into a clop scene, with Blueblood encouraging Rarity to get her dominatrix on)

You could have him in a session with Harshwhinny... come on, you know she seems like she'd be into it.

(yeah, there's already about 15 other stories with variations on the title, but none of them are about Blueblood. it was too good to pass up)

Everybody is hermaphroditic. Or Intersex, whichever term you prefer. Make of this what you will. Explicit sex is optional.

My Little Dungeon Keeper! (Not the official title...)

Sunset Shimmer, and/or Twilight Sparkle, are summoned by a Horned Reaper to free him by becoming a Dungeon Keeper.

(Sunset Shimmer and Twilight Sparkle are just the most likely possibilities, because the premise requires inter-dimensional travel.)

Inspired by Dungeon Keeper Ami.

Stiffing the Competition

Freed from having to blend in, male changelings are um... modifying their dongles. I mean, they're augmenting their package. Upgrading their hardware. Improving their penetration devices. Look, they're giving themselves big fancy dicks.

Pony stallions are understandably upset.

I think this is an amazing idea. But it's an idea, not a story. How can it be expanded upon it to write an actual story? Anyone interested in collaborating or taking it for themselves? There could be a lot of angles on this.

But no matter how big their dongle, a changeling still ain't getting anyone pregnant.
In modern society that's seen as a good thing though, isn't it?
Pony stallions are boned, aren't they?

cross posted on my blog

3700227 I feel like this really doesn't even need to be mature, just teen with the sex tag. The emphasis seems to be on what the sex means, not the sex itself. (maybe you also posted it in the "teen" catagory; I don't know.

5283271
It doesn't have to be mature, but I don't see a reason for it not to be, unless he turns her down. And I'm not sure he would. Discord's past behavior demonstrates he'll take a tiny part of what he really wants if it's all he can get.

Okay, so this was a story that I was going to commission and bounced ideas around with my chosen author for several weeks. Then real life happened and the author said he was putting off all commissions indefinitely. I poked around with a few other authors who I thought had a suitable writing style but no dice. Below is quite a bit longer than most of these posts and the formatting is a little odd and are addressed to an individual because its a bunch of pms that were written over several weeks edited together for coherence. I'm just getting the idea out there in some fashion knowing it will likely never be written.

Working title: Twilight's Futa Trilogy
A Mature story with the Comedy and Sex tags divided up into three main acts.

Act 1:
Having fun with the "alicorns are futas," and "ponies go into heat," clop tropes. Sometime around the middle of season 4 Twilight looks at the calendar and realizes that she's about to experience her first heat season with her new "male equipment." Twilight really hasn't thought about herself sexually until now. In Canterlot she considered a waste of time that could be spent studying. While when she moved to Ponyville her life just got so crazy that it never came up. Now forced to seriously think about it Twilight realizes she doesn't mind the thought of having sex with another mare. In fact getting another pony pregnant feels awfully appealing. While anyone might be a bit unsettled by discovering a kink they were previously unaware of Twilight pulls a Twilight and overthinks/overworries herself into a tizzy. Convinced that the first whiff of female pheromones is going to turn her into a crazed sex maniac she locks herself in the library basement. Spike has the girls come over to convince her that she's being ridiculous. A raunchy conversation comedy occurs through the basement doors. "Girls you don't understand. I can't come out. If I get a scent of any of you my unbound lust will Doom Equestria!"

Act 2:
After the climax of the previous act and having long talks with her friends about her sexual issues. Twilight decides the best way to come to terms with what she's become is embrace it. She can use her "new parts," to bring happiness and grant foals to mares who desire them. So she signs up at the town hall to be part of the government sponsored Ponyville regional stud service. When she's signs up she's assured that only a hoofful of mares a year use the service and that she'll have plenty of time to ease into it and adjust. She also asks her friends that if any of them are considering it that they hold off a bit because she considers them the sisters she never had and would find the whole thing awkward and weird. Cue dozens upon dozens of mares signing up.

I'm one of those people who thinks about story premises and plausibility regardless of that story's genre or origin. I suspect that many would look at my proposed story and say something along the lines of: It's a very silly comedy that clearly runs on porn logic don't overthink it. Those people aren't wrong. But for people like me I thought of a few questions I might ask when faced with a story like this and hopefully plausible answers for them.

Two related questions: First why have a stud service that results in kinky, steamy, porn scenes when a more dispassionate business like arrangement is more likely? Second Twilight is a genius with the power of an alicorn backing her up as well as an obsession with organization and efficiency. When faced with an overwhelming number of mares why doesn't she come up with a solution like: Through a combination of spells/potions to boost her sperm count and stamina use an "assembly line of quickies," to blow through the workload in a couple days? (ah-huh-huh he said blow, he-he snort-snort he said load)

The answer to both is that in Equestria the magical power of emotions is very real. Cadence's and Shining Armor's love bomb for example. Or Sombra channeling enough fear and hate to force a pyrrhic victory when faced with both Celestia and Luna at the same time. Ponies believe that the emotions and the magic within them are as important to a foals conception as the biology. They feel that while a foal can be conceived through joyless mechanistic sex to do so would result in a very dangerous pregnancy with a high chance of miscarriage. As such a stud's job includes trying to make the act as fun and enjoyable for themselves and their client as possible to maximize the foals health.

Another question that might be asked is doesn't this result in a lot of single mothers? My answer is the herd values in Equestria especially in small towns like Ponyville consider it the entire towns responsibility for the raising of foals mean single motherhood isn't looked down upon and studding is necessary for most because of the highly skewed male to female ratio.

Finally if Ponyville only had a slow trickle of studding applications only to get an avalanche when Twilight signed up for the job, doesn't that imply that most of the mares who did so had the rather shallow reason of wanting a royal bloodline foal and by extension are unlikely to be good parents?

Twilight is an overthinker too and the above question is something she might ask and worry about. I'm toying with her doing a lot of research into reproduction patterns and sociology and coming up with the following answer. Equestria is in a boom time. Princess Luna's return marked a new age of optimism and expansion resulting in a spike in birthrates. Ponyville in particular as a major rail hub (check out the official map) and location for the big regional hospital was a prime location for such. Twilight's ascension and the creation of the Crystal Tree Castle skyrocketing its prominence in the minds of the Equestria at large didn't hurt. Demographically speaking this studding boom was actually overdue. Or as I allude to with Rarity's sample dialogue in the next act that while the prospect of a royal alicorn sire was enticing for her and pretty much all the other Ponyville mares it was at most a small tertiary reason at best and all of them had other much stronger motives to sign up for the stud service. To sum up Twilight becoming Ponyville's town stud may have been the spark that triggered the surge to happen when it did. But it would have happened anyway eventually with or without her.

Of course that last question and answer is the one most likely to be cut in the actual story. Not only would it take up a valuable wordcount that would displace sexy shenanigans. It would also be the kind of long exposition that would be out of tone with the rest of the story and could bring the pacing to a halt. But if you can think of a way to milk sufficient funny from it then go nuts.

The part mentioned above about both the stud and client needing to enjoy themselves is the driver for Twilight in this act. Which sets up the three main sex scenes. The first of course is Twilight initially doubting herself and needing somepony to encourage her and get over her anxieties of her virginity making her not good enough: "Mayor Mare?!" "Hello Twilight, when I saw how many mares signed up I knew this would be enormously stressful for you. If you'll pardon my presumption I used my mayoral authority to ensure your first time was..." The Mayor ahems as she clears her throat "with a 'mature mare of experience."
The second big sex scene would be after Twilight has some real experience and gained proper confidence. This would be a bit of a breather where she and the readers just have some fun. I was thinking of a threesome with Vinyl Scratch and Octavia that has fun with how their sexual styles are just as different as their tastes in music.

The third main sex scene would be Twilight's first true great challenge as a stud to cap things off. A studs job involves making sure the client has a good time. How do you do that when your client is always angry? Enter Limestone Pie.

Spaced throughout when pacing allows would be little jokes about her experiences with her other clients. Portraying that the ponies of Ponyville are every bit as eccentric in their sex lives as they are everthing else. Twilight "I tell you girls I thought Zecora's rhyming dirty talk was strange but Golden Harvest's thing with carrots had it beat."

For the ending scene after the breeding season if over Twilight decides that she really needs to talk to somepony about what she just experienced and figures another alicorn would be best, but Cadance or Celestia would be awkward since they watched her grow up. Princess Luna's reaction isn't what she expected: "Let me see if I understand correctly Twilight Sparkle. In this era the stud service is no longer considered beneath our royal station?" Twilight awkwardly hmms. "As far as I know Luna." Luna smiles. "Wonderus news, I shall be unsurpassed at enriching Equestria by spreading the laughter of new foals." Luna's eyes narrow and her expression becomes competitive. "Your plan to obtain a head start was clever but you have made a tactical error. By only signing up for the local Ponyville register you have greatly limited you options. By signing up for the national register I shall be able to bring the blessing of the night to all of Equestria!"

Act 3
Opening scene: One year later after act 2 Twilight Sparkle is congratulating herself after the close out of her second breeding season as Ponyville's stud. Thanks to being forewarned of the demand this time combined with her scheduling, organizational prowess and judicious use of threesomes (adding that check box to the application forms was a stroke of genius if she says so herself) she was able to clear out both last years waiting list and everypony who signed up this year. She also noted that with some smug satisfaction that based on her correspondence with Luna that the Princess of the Night had forgotten to factor in travel times with her strategy of using the national register and by Twilight's calculations she had her beat by a good dozen pregnancies. Suddenly there's a knock and the door and Twilight is informed that Mayor Mare has gone into labor. (As a note My Little Ponies aren't human or Earth horses so giving them a long 12-13 month pregnancy to make this timeline work should be fair game.) After Twilight's panicked rush she arrives just in time to meet the Mayor's new foal. A strong, healthy, alicorn...

Sure enough over the coming weeks every mare Twilight impregnated gives birth to an alicorn foal. (Zecora's foal appears to be one third Zebra instead of one third Earth Pony but she's defiantly got wings and a horn) While the anti-surge spell discovered by Sunburst helps, the problem is that while it doesn't require a lot of power it does need a lot of skill and fine control to a level rarely found outside graduates for Celestia's school for gifted unicorns and needs to be cast every day. Meaning that while the prospect of several dozen successive baby alicorn magic surges doesn't spell certain doom. Probable doom is likely. Cue Twilight running herself ragged to keep Ponyville in one piece. One potential gag I'm fond of. Twilight is pausing at Sugarcube Corner for a quick influx of sugary energy. "Hey Pinkie, I just realized I haven't seen Limestone at the hospital yet. She's awfully overdue is everything okay?" Pinkie smiles "Oh Limestone had her foaling days ago. My family believes in natural birth at home." Cue a panicked Twilight rushing to the rock farm expecting to find a crater. Only to discover a completely nonplussed Igneous Rock and Cloudy Quartz. "Yes our granddaughter is a bit of a hoofful. But she has nothing on what Pinkamena was like at the same age."

Possible idea of how to resolve the crisis in the finale story: Since Twilight is busy running around Ponyville casting Fledgling's Forbiddance (I think that's the ant-surge spells proper name) she doesn't have time to research a long term solution herself so she calls for help and has her unicorn friends from CSFGU come down from Canterlot (and Lyra who lives in Ponyville) to assist Starlight Glimmer in figuring it out.

Starlight hits on the idea of using the Cutie Map to amplify the spell just like she did with Starswirl's time spell enabling Twilight to hit all of Ponyville with one casting. With further refinement they figure out how to use the Friendship Castle as an antenna to spread the spell Equestria Wide similar to how the Crystal Castle spreads the power of the Crystal Heart. Since the spell requires more fine control than it does power Lyra can cast it when Twilight and Starlight are away on Friendship Business.

Moondancer decides that it would be important to have more backup than just Lyra and volunteers to move to Ponyville full time. She and Twilight then suffer some good natured innuendo filled teasing about if Moondancer is about to become a Ponyville resident how long before she signs up for some "government services."

Sample dialogue for the final scene after things are resolved and calm down: Twilight is relaxing with the rest of the girls: "Well girls this has been the craziest few months of my life and from me that's saying something. But you know the smiles of so many happy mothers and their foals made it all worth it." Rarity "Ah that's good to hear Twilight. Could you by chance teach me the surge-control spell." Twilight "Thanks Rarity, we can never have enough unicorns who know that spell. Just in case." Rarity "Ah-heh, well you see my desire to know wasn't entirely altruistic as it were." Twilight raises an eyebrow. " Come again?" "Well, you see I've been worried lately that my career has been taking over my life with all the new boutiques I've been opening. And as Sweetie Belle has earned her cutiemark and grown more independent I was shocked to find that I missed having a small pony underhoof. Luna's royal stud service announcement and the prospect of such distinguished parentage sealed the deal. Shallow as that last reason might be."

Applejack fidgets with her hat "We were all gonna tell you sugarcube but we all saw how stressful last years breeding season was for ya and decided to not to add to it. We planned to when the season was over but then the Mayor had her foaling and its been crazy non-stop since." Twilight gives the gathered ponies a cool look. "So all of you knew except me?" Applejack fidgets with her hat again "Ah more than just knew. Ya see Granny's getting on in years and I knew she always wanted to see the great-grandfoals who would inherit the farm after she's gone. An Big Mac just never seems able to commit even with so many mares after him. So I figured it was time."

Rainbow Dash gives a half-hearted smile "I swear that I had a good reason with real depth to it like those two and not just because Luna is the hottest pony in Equestria." Twilight starts. "But what about the Wonderbolts?" Rainbow Dash returns Twilight's cool look with interest. "Please Twilight I was just lightening the mood. I'm not that irresponsible. I went over the maternity policy with Spitfire first and made sure there was good foal daycare available."

Pinkie Pie starts bouncing. "Ooh, ooh, quintuple baby showers are the best!" As Twilight looks to her Pinkie speaks. "Come on Twilight you knew I wanted foals of my own ever since the Cake Twins were born. They're getting older and don't need a babysitter as much. Plus Missus Cake confided in me that they don't have much more to teach me and my apprenticeship is almost over. The timing worked out well. And yes, Luna is super-hot."

Twilight's eyes briefly widen in horror after recalling her conversations with the Pie elders. Managing to only just control her expression she looks over to Fluttershy hiding behind her mane. "Well I suppose that whole quintuple part of Pinkie's statement tells me all I need to now about why you've been acting more skittish around me than you have in years." Fluttershy mumbles as Twilight continues "Its okay Fluttershy you were always the most motherly of the six of us. Now that the shock has worn off this is no surprise. I just hope Luna gave you a good time." Fluttershy takes a deep breath and braces herself to speak. "Luna isn't the sire. Remember the trip I took when heat season started. I did want a foal but I was so scared and decided I needed advice. So I went to see Cadance in the Crystal Empire.

Twilight smiles. "Cadance gives great advice and while her domain over Love isn't a perfect overlap between that and her own motherhood it makes sense as to why you'd go see her. I take it that after she helped you with your fears she hooked you up with the Crystal Empire stud service?"

Fluttershy blushes crimson. "Not exactly... You see after our talk Cadance and Shining Armor invited me to stay for a while to relax. We had such a great time and I got so comfortable with them that when my and Cadance's heat kicked in at the same time... The threesome just, sorta, kinda, happened..."
Twilight gapes aghast "Shining Armor is the sire for your foal?" Fluttershy turns impossibly redder. "Um no. Cadance is."

Like act 2 I have a question and answer for my inner pedant
If alicorns always breed true why were Celestia and Luna surprised by Flurry Heart or not warn Twilight about what trouble she might cause?

While I had Luna give a silly "studding was beneath royalty in past times," in the her sample dialogue the real explanation is that for a long time Celestia and Luna were the only alicorns. They ascended to the thrones young and were dealing with a highly stressful and chaotic rule at first. Discord, Sombra and Tirek are only the threats that happened to return in the present day. Countless others were vanquished and forgotten. It was no time to be thinking about foals as either sire or dam. When things stabilized enough that either of them might even consider it Nightmare Moon happened. With Celestia gaining double responsibilities for a thousand years the prospect of children dropped to the bottom of her priority list. When Luna came back they spent almost all their free time just becoming sisters again. So they had no experience or context to give a warning.

Just for the OCD of it I also pondered the logistics of Twilight's studding and how many mares she could potentially get pregnant per breeding season. As noted above Twilight needs to give every mare she services her full mental and emotional attention in order to give them the best possible time she can. That would be incredibly mentally draining even if you assume almost limitless physical stamina from being an alicorn. So she would need a proper long break between sessions. Realistically the mares would have variation from season to season as to when they individually go into heat and it would be difficult to schedule sessions exactly to the day in advance. Finally since part of the resolution of the first act is that while ponies go into heat its not some all-consuming thing and they have lives aside from it even during the breeding season. That means that scheduling conflicts with other things are inevitable. So I figured that around four sessions a day are about reasonable for Twilight with perhaps one of those being a threesome. So five pregnancies per day. My understanding is that most mammal breeding seasons are from 4 to 6 weeks long. I go with the higher number for 42 days times 5 pregnancies per day resulting in 210ish pregnancies per breeding season at Twilight's hooves (or other parts). Luna having long since mastered her pegasus speed and powers of teleportation gives a good go of it racing all across Equestria but can't quite match it during Ponyville's boom time. Though she will eclipse Twilight eventually when the boom ends in a decade or so.

Again the above ponderings have little to no place in the story itself. But I worked it out for story-plausibilty peace of mind. As noted before if you can think of a way to make the exposition seriously funny then consider it. Otherwise no need to bother.

Characters: Sweetie Belle, Vinyl Scratch
Description: Sweetie Belle wants to become a DJ. And who better to see about that, than Ponyville's very own Vinyl Scratch. However, Vinyl has a price for her lessons.

So I was thinking, what if Sweetie Belle got DJ lessons from Vinyl. And of course it had to turn into a sex fic...

Since I've already admitted my filthy mind once how's this for a story idea?

The Mane 6 have solved all the shipping by getting together in a herd. Now they want children. Twilight looks into the gender-swap spell now that she's an alicorn and might be able to cast it.

Rainbow: "Shouldn't changing our genders be way easier than turning us into breezies?"

Twilight: "The breezie spell was always meant to be temporary. Any small flaws in the casting wouldn't have any chance to show up before it wore off. The consequences of changing one of us into a stallion is in a sense permanent. Any flaws in the spell is something the ensuing foal may have to live with the rest of their lives. I think I'm going to need somepony else to monitor my casting and make sure its absolutely flawless and there's only one pony I trust to know I'm not making any mistakes. Hopefully asking Princess Celestia won't make me faint from embarrassment on the spot."

Applejack: "Sounds like this'll be pretty involved and we don't want to do it too often. There's all kinds of rumors about Zebra fertility potions. I'll ask Zecora if there's any truth to them. Try and guarantee this works the first time."

Twilight decides that for the first attempt she'll transform herself because naturally she knows her own body the best and will have the highest chance of spotting anything wrong with it.

Pinkie Pie volunteers to be the first mother.

It turns out Zecora does have something a fertility enhancing incense the scent of which puts mares in heat and gives Applejack a bundle.

When the day arrives Spike is out with Starlight Glimmer. While they're happy for the girls they have no desire to be there while their big sister/mentor is getting it on.

Celestia: "Hello my little ponies. I'm proud of you Twilight for having the courage to ask for my help. I know how hard it must have been. Truth be told you're not the only one nervous about this. I hope we aren't imposing but I thought having a second pony to observe the spell would be wise."

Luna: "Greeting beloved ponies. Let's get to work on making a foal for me to spoil."

The spell appears to be a complete success and Twilight enters Pinkie's room.

Pinkie "Whoa there stud aren't you handsome."

Twilight notices many, many incense sticks lit all over the room "Pinkie what did you do?"

Pinkie "The sticks were duds I couldn't smell anything from any of them."

Twilight "Many pheromones are scentless. You might have flooded the entire castle with their magic!"

The rest of the girls including Celestia and Luna come up from behind Twilight. "Hey Twilight we feel kind of funny and you smell really, really good."

Its a good thing alicorns have nigh limitless stamina.

Name: Twilight's a Foal-Fiddler
Tags: Sex (duh), Drama
Description:

Ever since the whole debacle of going back in time and stopping Starlight Glimmer, Twilight's had a couple of odd dreams. At first, they were nothing—just little scenes that would skirt by without her seeing the whole details and would forget in the hustle and bustle of the day. But they've gotten more vivid, intense... Erotic. Now, Twilight's discovered where exactly her "tastes", to speak crudely, lie in.

She's not taking it well.

TL;DR
Twilight has wet dreams about filly Rainbow Dash, eventually she starts fantasizing about other fillies and foals, and she is freaked the fuck out by this and tries to hide her newfound kinks and implications therein. Very drama based. Would eventually culminate in either Luna or Cadance (or both) finding out her secret, discussing with her why she has these likes, and how she could cope with it.

Fifty years or so after his marriage, Shining Armor is still in his prime of life. Nopony knows why - at first he assumed it's some spell Cadance or Twilight cast on him, but they're just as surprised as everypony else.

But now Flurry Heart's husband is also looking surprisingly young...

Several eager Twilight research sessions later, it turns out alicorn immortality is sexually transmitted. Nopony ever knew, because Celestia and Luna (are still virgins / never tried again after their early coltfriends got killed by some villain / something), and Twilight just isn't interested.

At first I thought this could be "T"-rated, but then I worked through where ponies would take it, and... Twilight would pour herself into finding some other way (if it's biological, blood globulin transfusions? But what if it's magical?), but somepony would try the other way. Just how many of Flurry Heart's old coltfriends are still in the prime of their lives?

6749871

So... assuming the "easy way out" is out, this would be an "awkward comedy" about Cadence talking Shining Armor into having sex with other mares^[1] - possibly even the rest of the Mane 6, because Twilight wants them to become immortal and she can't exactly do it herself (assuming R63-spells are impossible as implied during the "Magic Duel" between Twilight and Trixie).

^{[1] EDIT: Ah. This is why I probably should not post things right before going to bed. Obviously that doesn't make any sense, unless alicorn-immortality is commutative, which was my second idea, but it all ended up mushed together when typing it out. Woops.}

And, on a less comedic note - imagine the disaster, if the secret got out. Ponies would be falling over each other in a desperate bid for each princesses' attention (regardless of which one), misguided, shallow "romantic" advances from the "rich and noble", the elderly, and the terminally ill (!), and possibly even an attempt at kidnapping them for ... well, you get the idea.

And, purely rationally... even if an alternative solution is being worked on but still some ways off, the most ethical thing for them to do would be to visit Equestrian hospitals and nursing homes and have sex with as many terminally ill patients and elderly ponies as possible to save their lives.

Yikes!

it turns out alicorn immortality is sexually transmitted

Hold on. Is alicorn-immortality commutative? If somepony who had sex with an alicorn had sex with somepony else, would they also become immortal? That would solve the problem relatively neatly, just find some mares and stallions willing to "freely spread the joys of youth" across Equestria. I imagine Equestria's red light-districts would see a sudden spike in popularity and funding, and it'd play havoc with society's opinion of the subject.

"The Princesses are corrupting our youth!" and "Mothers against Immortality" would ensue.
