Since her return and rescue, Princess Luna has been looking for some way to properly honor the six mares who saved her from herself, but nothing she has been able to think of has seemed meaningful enough to repay her saviors.Nothing, at least, until she spends Nightmare Night in Ponyville, and gets to actually know the six ponies to whom she owes such a great debt. She realizes she enjoys their company, and wishes for them to spend more time with her, that she might grow closer to them.So, in accordance with many fine and ancient traditions, and after thinking it over for a good...couple of hours, easy, she proclaims that she shall marry all six of them. Oh, and that Twilight will be marrying Celestia, too.Now would be the appropriate time for everypony to panic.Can be found here
This fanfic provides examples of:
Accidental Proposal: It is revealed that Princess Celestia offered to officiate Twilight’s wedding back when Twilight was still a filly under her tutelage. Due to a poor choice of wording on Celestia’s part, Twilight has been living under the assumption that Celestia intends to marry her when Twilight decides she is ready.
Arranged Marriage: Princess Luna doesn’t propose to or even tell the Mane 6 of their reward, causing it to become this for most of them.
Perfectly Arranged Marriage: What Luna’s marriage reward is to Rarity. Exaggerated in that she still hasn’t seen Luna since the pilot episode, but quickly declares that princess Luna is her true love.
Bigger Is Better in Bed: Invoked by Pinkie Pie in an attempt to cheer up Applejack by comparing Big Macintosh to Princess Luna. However, it just squicks Applejack out more. Slightly off because Pinkie was comparing actual body size (such as height) rather than equipment length.
"There was, of course, one threat which she would act upon, a threat which was reserved for those select few who would stare back, unblinking, into the eyes of their princess, steadfast in their refusal to submit. It was the ultimate punishment for any member of her staff who found themselves the focus of the full ire of the Princess of the Day while still within the bounds of the law; the mere mention of which could transform the proudest of ponies into a quivering mass of tears and apologies. A fate that was, to some, more cruel than exile, or perhaps even death itself. She could just fire them."
Then it turns out that this is a horrible punishment, since the social stigma will pretty much ruin their reputation and life forever.
Despair Event Horizon: Discussed and defied, in a way. The Mane 6 are afraid of making Luna feel rejected, which might drive her to once again become Nightmare Moon. Princess Celestia is also trying to prevent this, as well as dealing with the fear that this may happen to Twilight if Celestia tries to correct the misunderstanding about the Accidental Proposal.
Didn't See That Coming: Twilight’s hurried plan to escape Ponyville meets an unexpected obstacle after gathering all her friends, only to discover that Rarity wants to accept the wedding and blocks Twilight’s magic.
Drama Queen: Rarity, as per the show. Rainbow Dash also acts like this while Rarity is trying to take her measurements.
Eating the Eye Candy: Despite Princess Celestia’s claims not to want Twilight in that way, she catches herself in an Imagine Spot like this. Subverted with the guards who are sent to retrieve the brides, who are using Saddle Arabia stories (Equestria’s version of Saudi Arabia and the famous 1001 Nights stories) as a guide to protocol and etiquette, and are afraid of getting punished if they do this.
Rarity does this upon seeing Shining Armor for the first time, before finding out he's Twilight's brother. Applejack and Rainbow Dash enjoy the view, too, and Dash doesn't even swing that way in this story.
When Pinkie mentions that she can finally throw the one kind of party she's never been able to before, Applejack runs through the list of parties she's thrown, eventually getting to the time she tried to arrange an orgy, at which point she begins panicking.
Shining Armor has an off-screen moment of this while offering Celestia tips for the honeymoon, only to suddenly realize that he's telling his employer/ruler how to have sex with his little sister.
Celestia tries to explain heterosexuality (and how it might interfere with a marriage involving 0 stallions) to Luna. Luna's solution is relatively straightforward and has appeared in other fanfics. Celestia's response? '“Luna,” she croaked, barely able to make herself speak, “in what possible sense is ‘grow a magical penis’ the simplest solution to any situation, let alone this one?” It was taking every ounce of her already depleted willpower to not snatch up something large, heavy, and solid with her magic and hurl it at her own head. “If the lack of certain tools was the only concern, there are artificial devices which can mimic the necessary functions, rendering the need for transmutation spell unnecessary. If Cadence is to be believed, some of them are quite elaborate, and enhanced by magic to seem very realistic.”' Followed by a near facehoof from Celestia ...
Failure Is the Only Option: Everything Princess Celestia does to get the weddings called off backfires, usually making the situation even more humiliating.
Fish Out of Temporal Water: The story begins on the morning after the Nightmare Night from the episode Luna Eclipsed, so Princess Luna still has these tendencies.
Which is of course Played for Laughs later, having Luna misinterpret a timid reassurance from Fluttershy as a sexual come-on, and then later Rarity's affection gives her the impression that Equestria is much more sexually open than it used to be.
invokedHo Yay: Much Les Yay is discussed, implied, and shown off-screen, but not described more than vaguely. Word of God says (in the comments under Chapter 6) that the main story will never show explicit sex, although the author is planning to create a side story for anything that would warrant a proper sex scene, for those who want to read about it.
Humiliation Conga: A lighter one, as well as being a heroic example that is Played for Laughs. As Princess Celestia tries to make a plan to get the weddings called off while appearing to go along with them, she is subjected to increasingly embarrassing things by Cadence and her friends, an enthusiastic Luna, and herself via Imagine Spots.
Princess Celestia has several involving herself, Twilight, and the possibilities that come with their marriage.
Spike has a few as well.
invoked Applejack has several we aren’t shown about her family, which acts as Nightmare Fuel for her. Later, she has an unwilling Imagine Spot of sleeping with Princess Luna.
Twilight's affectionate nuzzling at the breakfast table distracts Celestia as she is pouring caramel onto her pancakes, causing her to use too much. This causes Twilight to believe, ironically, that Celestia was having a UST-fueled Imagine Spot of pouring the caramel onto Twilight and taking her on the table in front of everypony, which then gives Twilight an Imagine Spot of herself covered in caramel.
Innocent Innuendo: Sweetie Belle is a fountain of this throughout her appearance in the second chapter, from asking Rainbow Dash to help the CMC "fill their holes" (in their Crusading schedule) to getting the cream filling of a doughnut squirted all over her face.
Lovable Sex Maniac: Rainbow Dash is this in-story. After Twilight accidentally teleports herself, Applejack, and Pinkie Pie on top of a sleeping Rainbow Dash, waking her up, the first thing she assumes is that they got drunk and slept together. She then congratulated herself and was “smirking despite her discomfort” (it isn’t made clear whether she was uncomfortable with the idea of sleeping with her friends or if it was from three other ponies laying on top of her). She is the most casual of the group about sex and occasionally teases the others, especially Applejack.
Rainbow, after seeing the ponypile mentioned under Lovable Sex Maniac, then sees Sweetie Belle. 'Oh no. Oh, sweet baby Celestia, no. I had too much game last night! Too…much…game!' She only calms down once she notices she'd been moved to Carousel Boutique and Fluttershy nearby passed out.
Mr. Fanservice: Shining Armor. Rainbow Dash brazenly admits to ogling him, and she isn't even into stallions.
Nerds Are Virgins: Twilight reveals that she is a virgin, but mainly because she is saving herself for Celestia.
Noodle Incident: According to Applejack, Pinkie has previously thrown several fake-murder-mystery parties, a real murder-mystery party and even took charge of a "festive" search party. "Still not sure how you managed to pull that one off but the foals were found, and everypony enjoyed the gingerbread house, so Ah’ll give it to ya."
In Chapter 5, Celestia ponders how to handle Luna's reaction.
‘I can try to talk to her, but she seemed so happy about the idea last night…and the last time I told her she couldn’t have her way, things went…badly.’ She shuddered as she remembered that dark day. ‘And the time before that, she embraced evil and tried to destroy the world.’
Oh My Gods!: Two mares are called on to help tutor the Princesses in how to deal with marital duties. One yells out '[B]y Celestia's perky nipples, don't stop!'.
Celestia: Don’t even ask, Luna. I don’t understand why our subjects invoke them, regardless of relative perkiness.
Only Sane Pony: Princess Celestia starts to believe she is either this or has gone insane herself. Applejack also feels this way during Twilight’s Sanity Slippage after discovering that some of her other friends don’t object to their engagements with Princess Luna.
Open Mouth, Insert Hoof: Princess Celestia does this literally while discussing the engagements with Luna and inadvertently steering the conversation to a topic she does not want to talk about with her little sister.
One subversion would be the Apple family’s homophobic outlook, which prompted the family elders to try and get a gay stallion exiled from the family. Fear of Granny Smith’s reaction to the engagement (which is polygamous as well as homosexual) is Applejack’s driving motivation for being against the weddings.
Shining Armor is fearing for his life after realizing that he and Cadance and far enough along in their relationship that he is ready to ask for Celestia's blessing before proposing, yet still hasn't told Twilight about them. And that they will be spending a lot of time together.
Power Incontinence: Princess Cadance has a case of this, spreading love and happiness without conscious effort, especially when her concentration slips.
Power is Sexy: Princess Celestia thinks she accidentally did this to Twilight’s brother Shining Armor when she uses her power to back up her authority as princess. She didn’t, but nopony tells her that.
Prince Charmless: Prince Blueblood’s status as this is discussed in a conversation between the royal sisters. Princess Luna mocks him for this and Princess Celestia mentions that his attitude has actually been the norm amongst Equestrian princes throughout history.
The Quiet One: Big Macintosh is still this. Fluttershy is also this, having only small parts in the conversations she has been involved in.
Really Gets Around: Big Macintosh. Rainbow doesn't seem to mind the concept either, although no proof is given of if she does.
Reasonable Authority Figure: The guards sent to escort the brides-to-be back to Canterlot are about as respectful and accommodating as their orders allow them to be, considering that said orders are the standard boilerplate for apprehending criminals, just with a few words switched around.
Romantic Seven Girl Friendship: Princess Luna’s marriage plan was intended to be non-romantic, as a way to reward her saviors and become friends with them at the same time. Only Celestia realizes what she meant though.
Royal Harem: The premise of the story has Princess Luna marrying the Mane Six, which convinces them that they are going to be this for Luna. The story also mentions that Princess Celestia used to have one, but gave it up for the sake of her public image.
Runaway Fiancé: Twilight’s plan for dealing with the problems Princess Luna’s engagement announcement causes. It doesn’t work, because Rarity wants to accept.
Running Gag: It's a comedy, so there are quite a few of these.
Sanity Slippage: Twilight suffers a minor one early on, after learning of her engagements from the reporters. Also happens to Fluttershy in similar circumstances, with both Played for Laughs.
Celestia starts showing signs of this, too, including praying to Discord for help.
Secret Relationship: Played with. Celestia’s proposal to Twilight is common knowledge, to the point that Rarity and Applejack imply that even most citizens of a country town like Ponyville know about it. Celestia herself seems to be one of the only ponies in Equestria to not know about it, at least until the third chapter.
Sex Comedy: Sort of, except that Word of God has declared that there will be no sex scenes or explicit content in the main story.
Slice of Life: There is no major antagonist so far, just the Mane Cast dealing with Luna's eager attempts to reward her saviors possibly causing problems. The story mainly takes after the show's Slice of Life episodes, but with a slightly different sense of humor.
Shining Armor gets this as he realizes he's casually talking to Celestia about how Twilight's sex life will be affected. Celestia's had her share as well, trying to not imagine BEING Twilight's sex life.
Celestia herself finds the graphic tutorial Luna had requested on mare-mare marital relations to be more than she really wanted to deal with.
Straight Man: Princess Celestia and Applejack see their situation as a crisis and attempt to take it seriously.
Tap on the Head: Twilight thinks this will help (Rarity at the time was blocking Twilight's efforts to teleport away, and if Twilight broke through, it could accidentally kill her). Applejack shoots the idea down quickly, citing the apparently unexpected detail that having a strong horse kick her friend very hard in the head might be slightly fatal.
Teacher/Student Romance: Sort of. Due to Princess Celestia’s Accidental Proposal, Twilight thinks they are this and has looked forward to the day she would be ready to accept Celestia’s offer for most of her life. Celestia is playing along with it to avoid breaking Twilight’s heart while trying to convince herself that she doesn’t see Twilight like this, although she is clearly tempted by her.
That Came Out Wrong: Princess Celestia’s poorly worded offer to officiate Twilight Sparkle’s wedding is taken by everypony to be a marriage proposal.
Unresolved Sexual Tension: Celestia has a lot of this, not having indulged in her desires for several centuries. Cadance and her friends did not help her self-control.
Twilight also has a considerable amount of this from never having slept with Celestia, and Spike's insistence on sleeping near her keeping her from masturbating at night. Twilight's paranoia and libido has convinced her that she needs to show Celestia that she is willing to be intimate with her Princess, even if that means sleeping with her before the wedding night, leading Twilight herself to assist in Celestia's accidental seduction. As of chapter 8, the UST is now to the point that Celestia is having trouble restraining herself from being affectionate with Twilight.
Rainbow Dash is starting to feel this as well, since her main motivation for marrying Luna was being attracted to the Night Princess, and she hasn't gotten any closer to her even as both Rarity and Fluttershy have begun making their moves.
Unwanted Spouse: Although not married yet, Luna’s reward is this to Applejack, Fluttershy, and possibly Twilight.
Twilight has decided that she isn't interested in marrying Luna, but unsure of how to bring it up. Fluttershy seems to have changed her mind, however, possibly due to UST.
