After she gave Fluttershy the address, said her goodbyes, and apologized for bursting in so suddenly (not to mention leaving so suddenly), Twilight started trotting back to Ponyville. Today was special- With Fluttershy likely heading to the shop, Pinkie Pie out of town helping the Cakes at a baking competition, and Rainbow Dash on a bit of long-ranging scout duty for the Weather Patrol... Even Spike was set up with the special task of running the library alone, with a promised reward of topaz-lemon cake upon her return. Almost everypony she knew in Ponyville was gone or busy, but Applejack and Rarity were free. And so was she. And nopony in town would know where they all were or were going, which was good, because the other two mares had decided to, as she put it the other week, "show her the ropes". She was excited, the nervous kind and the warm hard-to-walk-straight kind.

She was on the way to the Carousel Boutique to... She had no clue. She didn't have the faintest idea what she was going to do with, or for, or around, the other ponies. She knew what it was about, and she was so so grateful to them. The more she read, the more she realized that what she asked them- To help her study and figure out that- is something you would never ask anypony outside of, like, a committed relationship, or a physician, or somepony like that. But she had done it, out of her ignorance (how she hated that word) on the situation. And they... Were OK with it. They accepted. So she owed them, quite a bit, and didn't want to face the fact that she could very well be heading to her friend's shop to...

She still had no idea.

--------

In a burst of power, she landed inside Carousel Boutique, in a private little curtained area. Rarity had set it up for her arrival, a place to teleport where other ponies would not see the flare. It was very forward-thinking of her, which was one of the things Twilight found she had most in common with the fashionista. However, the other pony certainly had the ability to be spontaneous as well, which is why Twilight was so surprised when the curtain pulled aside to reveal the stage from their little private fashion show the year before. And on it, a well-made and elegant bed easily large enough for three.

She'd be lying if she didn't admit how much that sight excited her. She had avoided contemplating just how serious the other two were about this, and that... It could only mean good things, or at least exciting things, which according to Dash was most good things anyways. For a change, Twilight was inclined to agree. Applejack and Rarity had been sitting at a table, having snacks with what looked like tea, but stood to greet her.

"Twilight! So glad you could make it."

"Shore is a pleasure seein' ya here, Twi. We thought ya might not make it."

"I'm sorry! I just got caught up talking with Fluttershy after I got back and-"

"Don't worry about it dear, Applejack was merely kidding. Wasn't she?"

"Well, just ah' bit."

Rarity gestured over to the stage.
"Well, shall we get comfortable? I imagine this is going to be a fairly long afternoon, and maybe evening."

"Sure! I'll just set my stuff down here- I brought some of my study materials just in case."

"And there's our proof that you are Twilight Sparkle, and not an impostor."
They all shared a laugh as they moved throughout the room, dropping off saddlebags, setting up lighting-- Not the bright focused magic of the last show the stage was used for, but a soft, normal glow- A bit darker than she was used to, actually. But it felt right, and as she was increasingly aware, this kind of thing was less about rote knowledge (although that didn't hurt) and more about feelings.

"What was that about feelin's, sugah?"

"Oh! Ahehe, sorry. Didn't think I said any of that out loud."

"Well, actu'lly, good thang ya did. Because... Twilight, I jus' wanna go over somethin' before we do a single thang, OK?"

"Sure!"

"If either of us... If me or Rarity, do anything you don't like, you tell us to stop that instant, ya hear?"

"Um... I'm not really sure what you could do that would be like that, but alright."

Applejack's voice dropped, not all the way into a whisper, but to a soft and tender voice.
"Well, it's just... You wanted to know more 'bout this, right? So we're, uhm, gonna be treatin' you like we would each other. A bit more of a hooves-on demonstration, if ya catch mah drift."

She burst into a crimson blush as she got the message.
"Oh! Oh. I... would you two really be OK with that?"

"OK? Sugah, I dare say we'd be happier than ya know. Yer a friend, and a right good one."

"And that isn't, um, cheating, or anything like that?"

"Now Twi, how could it be cheatin' if we're doin' it together?"

She thought about it for a moment. Certainly, she had no experience in this field, and was requesting their help. They had experience she did not. And, admittedly, it might have been entirely normal for her to feel this excited about being physically... ‘close’ with two of her closest friends. Yes, sure, it may be mentally or sociologically abnormal. But she lived in Ponyville: What wasn’t?
"Sounds reasonable enough to me."

Applejack nuzzled her neck and then stepped back, giving Rarity room to take her place. The fashion pony looked at her appraisingly, making Twilight feel a bit more nervous, but at the same time... She was kinda comfortable with it. Maybe even liked it a bit.
"Well then, I suppose it would be most advantageous if you were to... show us, what you know so far. A demonstration."

"Hmm?"

"We can't very well just teach a student without knowing how far along they are, could we?"

"That... makes sense, yeah."

"I figured you'd like that analogy. Well then- The floor, or the bed as it were, is yours."

Twilight had heard of stage fright before. She'd even had it, during her entrance exam to Magic School. She was not entirely sure if anypony had ever described the state of "stage arousal". But she could worry about dissertations in pony psychology later. Right now, two of her best friends were watching her with utmost sincerity, and that fact was leaving her dizzy and flushed and eager. Here goes nothing...

--------

They watched in silence as Twilight put on her demonstration for them. Their expressions were unreadable as the lavender mare stroked her own mane and hips, their reactions non-existent as she rutted into the edge of her own hoof. They stood close together, blushing faintly, tails whipping, but apart from this, made no statements or signs. And when the mare climaxed, groaning and hissing out a name (which they studiously ignored) from between clenched teeth, they simply applauded softly, respectfully. They gave Twilight a moment to relax and recover.

But then Rarity simply had to speak up.
"Twilight, dear, is that all?"

"All of...?"

"All that you know so far."

"Oh. Yes. I mean, it's only been a few days, and I... may have had some other subjects occupying my time."
Rarity wasn't entirely sure why Twilight was blushing (apart from the obvious reason), but she nodded regardless.

"Well, I suppose that simply means we have to work extra hard tonight."

Applejack bumped her flank with her own, laughing.
"An' I reckon hard work is exactly why ah'm here, right Rarity?"

"Mmhmm, absolutely."
They shared a kiss, more passionate than she had been expecting, and when she saw Twilight openly staring out of the corner of one eye, she seized up in Applejack's grasp, suddenly hyper-aware of everything the mare made her feel when they kissed. Heat and comfort and that fuzzy tingling sensation, her ankles curling and neck rolling, trying to press herself further inwards.

"Wow. Girls, that was... really beautiful."

"Aw shucks hun', t'aint nothin' special."

"I would argue that you are always special, to me."
It was absolutely worth the slightly saccharine comment to see the farmer blush like that. Revenge for such a fierce kiss, in her way. Applejack shook herself out of it, however, and turned to Twilight.

"So y’all just figured this stuff out a few days ago? Are you sure you're our age?"

"Uh..."

"Applejack! What a rude question to ask a lady. Just because she is... new, doesn't necessarily make her immature. As I said, it just means we'll have to be very... in-depth with our education."

"...Never thought I'd like tha sound a' schoolwork, but Rarity, you make it sound mighty nice."

"Flattery will get you everywhere, darling. Now then..."

She approached Twilight, trying to keep a predatory smirk off her face. This kind of delicious situation was normally limited to the non-reality of her favorite trashy romance novels. But here they were, a pair of marefriends and their mutual close compatriot. And they were going to be doing dirty things, lovely things, to each other, in front of one another. She almost let out a soft whicker at the thought, but decided instead to question their guest.

"What do you want to learn?"

--------

"What do you want to learn?"

The question hit her surprisingly hard. She hadn't even considered narrowing down the possible scope of subjects to cover, one of the most critical things you do before studying anything! Alright, think Twilight, what did you do the last time you forgot to prune the topic-tree, metaphorically speaking, right before an exam? Ah, that's right: Panic. OK, so the time before that... Oh!

"A... bit of everything?"
That was apparently the right answer, or close enough. Rarity stepped onto the bed with one hoof and pulled herself level with Twilight, eyes warm and smile wide. Twilight gulped in nervousness- She hadn't expected so much proximity, so fast, and on a bed... it was a bit much for her. Well, no, actually, she might have been imagining and looking forward to just such a scenario, but the actual reality of it was hitting her rather forcefully. She closed her eyes and puckered her lips, as best she could without any practice. A moment passed. Another. Finally, she cracked one eye to see what was going on and saw Rarity looking at her even more nervously.

"Oh! My, ah, apologies..."

"Rarity, it's alright. Is something wrong?"

"I, well, that is to say I... I can't. I just can't bring myself to kiss you."

The words stung at first, but then she realized Rarity didn't mean anything was wrong with her. And this was confirmed when Applejack sighed dramatically and cantered up to them.
"Come on now pretty-pony, don't tell me ya'll can't do it."

"Applejack, you don't understand. It's just... I was raised to think of that as something very important. Something with significance. Especially somepony's first, and I..."

"Well shucks, it's not like I was yer... I was wasn't I?"
Rarity just nodded silently, and Applejack moved next to the bed and nuzzled her gently. They shared a kiss, this one soft and tender, and Twilight smiled. Even in a rough patch, even in the strangest of situations, their bonds were strong.

"Now, mm, Twilight, ah hope ya don't mind, but I think we're gonna skip that part of the lessons."

"No problem in the slightest, girls! I'm pretty sure I can take care of that one myself."
They shared a laugh, and then Applejack and Rarity glanced knowingly at one another.

"Time to begin, my dear?"

"Eeyup."

Twilight really wished, afterwards, that she had been allowed to take notes.

Or pictures.
