The rest of the meal had been uneventful: Rarity had continued to glaze over in contemplation of this newfound idea, Applejack still shot her the occasional blame-filled look for giving Rarity the idea, and Fluttershy simply held close to her, nuzzling her chest from time to time. The bottle of Sky had long-since been finished, and she requested a second, somewhat older vintage, to take with her. In the future, perhaps she could see if the grandfather in question had any bottles of the truly old brew... She had missed it more than she thought. Mayhaps it was just a reminder of the bygone times, or of what she shared with her sister... Regardless, she was glad to have it back.

And speaking of backs, Rarity was placed unceremoniously upon Applejack’s back, having finally suffered the toll of a dozen caps full of Sky- She was, to use the modern vernacular, ‘blotto’. If the bottle had been any older, she would likely still be on her feet, practically incandescent with energy and roiling with a lusty heat. Applejack may be in for a surprise when she returned her marefriend home...

And speaking of marefriends’ homes, she was now returning her dear Fluttershy to hers. Returning with her, in fact- It was time for her love to sleep, and her to rest as well. While she normally chose a nocturnal schedule, like Celestia she was adaptable enough to stay awake for months or years on end, resting at any time of day without true sleep. Of course, she was currently not interested in rest- Discussions of lovemaking and her ‘other’ Regalia had left her in a bit of a mood, and Fluttershy clearly noticed. While her marefriend was normally very reserved, or so she had felt so far, there was a notable affectionate sway in her walk now.

“Love?”

“Mmhmm?”

“Would thou care to... retire, to the house? Perhaps to the bedroom?”

The pegasus blushed, wings fluttering for a moment.
“I would really like that. I had a... question.”

One could not blame her curiosity for being piqued at that moment- What sort of question? They had already been intimate. Could it be that she had... a request? Some kind of action or activity for which she held a heretofore untold attraction? Oooh, the potential was... Well, it was making her think like her sister. No need to immediately presume the most perverse potential from somepony in a position like this. But regardless, they sped up, reaching the house quickly. The door shut behind them, and Fluttershy turned to her, leading with a kiss and the element of surprise. She gladly pushed into it, tongue flicking out to taste the remnants of the deep and fruity tea she had been drinking. Hopefully, her own breath was not redolent with the Sky- Fluttershy had brought up her low tolerance for drink earlier.

“...Luna, do you have that bottle of the drink from the restaurant?”

But she had just been thinking...
“Art thou sure about thy wish to try it?”

“Well, um, I... I really want to ask you that question, but I wanna work up the nerve, and I don’t know if I can do it on my own, so... Yeah. A drink wouldn’t hurt. Just the one though! I don’t wanna end up getting dragged home like Rarity did, although we already are home, and you would be able to use magic, and...”
Luna put a hoof to her lover’s lips, silencing her. Fluttershy lowered her head.
“I’m stalling, aren’t I?”

“Just a touch.”

They shared a laugh, and she undid the top of the bottle. A carefully-measured shot, this particular one a startling mix of pink and blue, tinged yellow where it met the stone.

“Oh my! It doesn’t look like the same drink at all.”

“Well, I requested a somewhat... Older vintage. Not too old, I assure you. But perhaps We know of a better way for thee to take this drink.”

She nodded to Fluttershy before slipping the cup to her own lips. She drank quick, and deep, closing her eyes for a moment to savor the taste. Morning Sky was stronger, and tasted the same- Bright lemon began to give way to startlingly potent blueberries, a faint and distant echo of rose petals behind them both. Leaning forward, she nodded to Fluttershy, who realized what to do. They kissed again, their heated breath mingling across the pool of bitter drink. She tilted her muzzle forward, sending most, but not all, to her lover’s mouth. She could feel the gasp when it hit her tongue, and broke the kiss to let Fluttershy truly appreciate the beverage.

Her eyes still starry and dazed from their embrace, it took her love a moment to process what had gone on, and another to swallow the share of drink. Almost immediately Fluttershy’s face brightened, her smile becoming somewhat more sultry. If she truly processed her alcohol that quickly, Luna was impressed- But more likely than not, it was the sensation of a drink she needed, that one little push to being able to say her peace. Which she did:

“Luna, I want... I want to pleasure you. I’ve, um, never done it with a mare before, or anypony actually, and... I want to learn how to do it right, right away. I would feel so bad if I didn’t do well in the future, so... Can you teach me?”

Her own smile grew seductive, and her wings flared open into full attention-grabbing span, all the better to get an appropriate reaction. Teaching was not her strong suit, such was more her sister’s path. But given the circumstances, and the mare in question...
“With pleasure.”

“I hope so!”

They laughed, and Fluttershy led her up the stairs- To the real bedroom, this time. Luna would have been lying if she said she was not excited, for a multitude of reasons. With any luck, Fluttershy would be a quick learner... And if not, this was the definition of ‘education’ that meant going slow had benefits all its own.

--------

Fluttershy had a very intimate understanding of what it meant to be nervous. She felt it near-constantly- When she was caring for a particularly recalcitrant animal, when she had to go out in public, when she was forced to model. The time that she faced down a dragon (or a cockatrice, or Discord, or Nightmare... Nevermind) or the time she dealt with Gilda. Nervousness was part and parcel with her very being at this point, and she was immaculately... Comfortable with it, if something like that was actually possible. But this particular brand of nervousness? The kind where, underneath the jitters and the jumpiness and the flitting eyes, she found an intense heat in her core? That kind was new. It was, dare she say it, exciting.

Of course, part of that excitement could easily be attributed to the shockingly-strong alcohol already coursing through her. Or the Princess of the Moon lying demurely on her bed, tail occasionally whisking aside just a bare inch to reveal her private places and a faint whiff of her scent. It was heady and deep and intoxicating, even from here. She nickered, leaned in, and did her best to smile seductively. It probably came off as creepy or off-putting, but you know what? She wasn’t worried for once. Again, maybe the mare, maybe the booze, maybe the situation. But she felt ready. And so she...

She had no idea what to do now.

…

Aaah, there’s the good old-fashioned panic. Always comes back when you (don’t) need it most. She shook her head and looked to Luna, trying her best not to have a pleading expression.
“I, um...”

Luna looked over her shoulder- Fluttershy could tell that if they were face to face, she would be getting nuzzled at this very moment. The look in her eyes was more than enough comfort, however.
“Be calm, love. Instruction was thy wish, neigh?”

“Yes. I really want to do this right. I just... I really don’t know how to start.”

“Well, under normal circumstances, a kiss or an embrace. Perhaps several. Of each. But we are both quite close tonight, so let us move directly to the critical portion. Come closer, dear.”

She stepped forward, timidly, making her way to the edge of the bed and pulling herself up with one hoof. This close she could feel Luna’s body heat- Not oppressive, almost not present at all. It was more like the cool pressure of a spring night coming in the window than it was a normal pony’s presence. She moved closer, and Luna smiled.
“Good. So... Hast thou groomed another before? Our previous encounter notwithstanding.”

Fluttershy thought back to her days in Flight Camp.
“Um. Rainbow Dash, once. She had a hard day at practice, and we had just learned how to preen properly, but... I didn’t do much more than the basics, and it was all on her wings.”

“Then start there, love, and let us see what we have to work with.”

Nerves jangled as she moved closer, pressing her side against Luna’s. Their size difference paradoxically made this easier- Her muzzle was level with the Princess’ wings to begin with, so there was no need to bend down or lean from above. Carefully, slowly, she moved her lips across the folded surface of the wing on her side. It was delicate work, and slow, given that her single instance of practice was years and years ago, and on a pony her own size to boot. But sure enough, she got back into the swing of things after a bit, using her lips and teeth to tug at the feathers and re-align each one. Soon she could put a little more force to use, applying pressure to the muscles beneath. Her marefriend responded to the first bit of pressure with a lovely groan, so she kept going.

A few minutes passed this way, interrupted for a moment by Luna unfurling her wing to give her better access, and then again as she switched sides. Her climb across Luna’s back to reach the other wing left her embarrassingly aware of how much this little bit of physical activity was already exciting her. The moment her legs stretched wide to pass over the alicorn mare left a twinge rocking up her back, and she blushed fiercely despite nopony being able to see her. The right wing went faster now that she was in the groove, and soon Luna was happily humming as she worked, flank bobbing to an unheard beat.

“Does it all feel, uhm... Correct?”

“Yes- Very much so. I believe now would be a good time for a kiss.”

It wouldn’t have been entirely wrong to say Fluttershy took that as an order- She moved forward quickly and kissed passionately, her tongue darting out almost immediately. If Luna was surprised, she certainly couldn’t see it- Her eyes were closed, focusing on the beautiful taste where they met. A needful whine built up in the back of her throat, but she bit it back and kept her lips and tongue moving, humming her own little tune into the Princess’ mouth. They parted slowly, lingering pecks and nips, both of them panting from time to time. She looked into Luna’s eyes.
“Next?”

“Mmmh. If this were not a lesson, I would say to do that again... and again... But for now, it may be prudent for me to stand.”

Luna did- Walking off of the bed, graceful as ever, she turned her tail back to face Fluttershy, flicking it once. She got a tantalizing view of what lie beneath, and another head-fuzzing hint of that musk- Stronger now. She gulped and stepped forward, tamping down her ever-present nervousness with a healthy dose of arousal and a little touch of willpower. Before she could get too close, however, Luna cleared her throat.
“As much as I would love thee to jump straight into things, for now start lower, or higher- The legs, or the flank. It is best to create preamble so as to make the anticipation grow... As well as other things, t’were a stallion involved.”

Welp, there goes her blush record, shattered in no time. She decided to start low- Again, a decision more or less made for her by their respective differences in size. Luna was not wearing her Regalia (not even the special bits) at the moment, so Fluttershy could clearly reach the curve where her hooves met the rest of her foreleg. Unsure, cautious, she gently kissed around the base of Luna’s hooves, eliciting a short giggle. She moved higher, and went a little further, short little nips and tugs with her teeth. The Princess’ coat was immaculate, and her skin hotter than it had been before- Or was it just how close she was, or her own ‘heat’? Regardless, it made her dizzy, in a good way, so she kept going. A nuzzle against her hock and then the trail of kisses moved up her thighs, reaching higher and higher and-

“Mmh! Ah. Let us... stop there. For a moment.”

She did her best to hide her disappointment, looking obediently past Luna’s (gorgeous) flank to make eye contact.
“What, um... next?”

“Let us continue to be motivated first and foremost by the educational aspect- Do what you did not before, which is to say, start from my flank this time. I would not mind thee applying more... force, there.”

She nodded, realizing that this would put her mouth within striking distance of Luna’s cutie mark. She could seize that opportunity when she got to it, however: Right now, she should start slow. Kiss her flank, just at the barrel, move back and up a little, even if you have to stretch and flutter to reach... Mmh. Luna said to use more force, so, maybe she could risk a little nibble? That struck her as entirely reasonable, and she did- She got a positively lovely growl of support in response, her marefriend relaxing and lowering herself slightly. That made reaching her entire flank a much easier task, so she roamed around, never quite hitting the cutie mark- Fluttershy wanted to save that for last. Well, second-to-last.

Eventually, she was running out of coat to cover, and had to go for it. It was certainly faster than she had expected- It was easy to forget just how huge Luna’s cutie mark was, a nebulous cloud of darkness spilling across most of her flank, a perfect crescent moon suspended in the core. Nervous, flushed and eager, her own hind legs rubbing together, she leaned in...

“Oh! Oh Fluttershy, please... Again.”

She took the encouragement to heart and kissed the edge of the mark again, nibbling a path around the outside. There was a tiny gap in the shadows where Luna’s normal coat peeked through, and she took the chance to bite a little harder there- Luna outright moaned at that, and she tittered with pleasure before moving on. Gentle kisses mixed with soft nibbles and outright hard bites, all across the surface, until she reached the moon itself. There was really only one option here- She couldn’t think of anything else. So Fluttershy put her tongue out and ran it across the entire length of the curve, pressing close. It was a good thing she did- Luna shivered and bucked, nearly breaking her contact. And it was just so silken and smooth and it felt right under her tongue... She didn’t want to break away until she had to.

But she did, just long enough to jump to the other flank. Luna’s shocked gasp when her tongue lashed out right away was matched a second later when Fluttershy decided to use her hoof to massage the poor mark she had left in the cold. It was a bit of a stretch to lean across her backside like this, but it let Luna coil her tail around her neck, nuzzling her and enrobing her in the cool softness of her hair. Those gasps turned into labored panting and deep shuddery breaths soon enough, and Fluttershy broke away, despite her reluctance.

“So, should I...”

Luna didn’t answer. Well, not with words. Instead, she pulled herself to the side with one step and flicked her tail up once more- This time, however, it settled around Fluttershy’s neck and shoulders, leaving her totally covered. It was a delicious cool sensation, and her nose... Oh. Oh dear. She had thought the scent of her lover’s musk was strong enough to make her worry before. But now... Now she could hardly think or concentrate, the scent was wrapping all around her, and oh mercy the heat, the air was humid and right in front of her... She wanted to lean in and let her mouth fall open and just let things work themselves out.

She gave in to that instinct.

It was apparently a good idea, if Luna’s reaction was anything to go by.

--------

At first she had thought her marefriend an atrocious tease to leave her in such a state. But now, the eager young pegasus buried face-first in her marehood, she was positive Fluttershy was anything but a tease. Her hooves were stamping with nervous energy, her thighs and coat already slick, the entire room redolant with the smell of arousal- Not all of it hers, either. Occasionally she found the breath and consciousness needed to coo out a brief direction, leading her love this way or that. After a few minutes she felt ready to guide Fluttershy all the way down to her clitoris, and the first time that received attention she nearly fell on the spot. One could call her a natural talent, at this rate. But then the lovely wet heat caressing her folds was gone, and she could feel Fluttershy backing out of her tail.

“Um, Luna...”

Ahha. Apparently the talent had a suggestion.

--------

Oh. Oh sweet (literally) Princesses the taste. She had never really thought about it before, never thought to try in relation to herself, but... Her entire face was damp with Luna’s flavor, her mouth filled, her tongue coated. She was going to remember this taste for as long as it was possible, and... Oh. Now Fluttershy wasn’t quite sure she could ever look at Luna the same way- Not knowing this. Whether or not it was normal to feel this way about your lover’s juices, she didn’t know and didn’t care. But right now, she had something slightly more romantic managing (barely) to make it to the forefront of her mind.

“Um, Luna...”

Her marefriend looked back, eyes slightly wild. Her voice was strained as she replied.
“Yes, milove?”

“I wanted to try... something else. Can you, um...”

She explained herself, and Luna nodded. They changed their positions, and she looked at the new situation. Now Luna was on her back, hooves up, in Fluttershy’s bed. Fluttershy herself was positioned at the tail-end of the bed, looking down on her lover as she bashfully covered her sex with the starry cloak of her tail. She leaned down and nudged it aside, gently nipping at one of Luna’s breasts as she did. The squeak she heard was almost like one of her own, and she couldn’t help but laugh. But then they locked eyes.
“This way... This way I can see you. As I, um... Yeah.”

“Oh Fluttershy... Go on. Let us finish thy lesson.”

She got back to studying. With any luck, there would be some kind of ‘joint session’ after this- The other reason she asked for the position change was that now she could free up a hoof to work furiously between her own hind legs, barely managing to sate the burning heat in her loins. And every time she lapped her tongue across those sweet lips again, the flavor only made it stronger. But she could hold on. She could be strong. It was her duty as Luna’s marefriend to make her come like this. And if that meant she had to wait for her own release... Well, she could stand it.

Probably.

--------

A broad swipe of the tongue passed over her, and she groaned. A hoof pressed against her entrance, and she shivered. Teeth chasing around her nipples, only to dart down and take the barest brush of her nub, left her crying out for more. But she would be an irresponsible lover if she left Fluttershy untended this entire time. The lesson was complete, and now they could move on.
“Fluttershy, dear, stop so that we may be together.”

The pegasus shook her head (sending a ridiculously strong bolt of pleasure through her) and continued to lap and suck and kiss. Luna groaned and bit her lip, trying not to buck. Her voice was restrained, albeit barely, and her strength was suppressed, again just barely. She tried again.
“Darling...”

This time Fluttershy responded by pursing her lips around one nipple and pulling, leaning back and making her eyes go wide. Her hips floated off the bed, bucking against thin air... Only for thin air be replaced again by that insatiable mouth. Her jaw went slack and she started to lose control of her voice.
“Fluttershy! We must really... nnngh...”

Two slender forelegs wrapped around her own thighs, pinning her in place and letting her marefriend get even deeper, tongue darting into her depths. She was beginning to shake from head to hoof, and when the mare’s nose began to rub back and forth across her hood, she was almost entirely gone.
“Oh nevermind. Please, please finish me.”

At that, Fluttershy looked up, never once breaking the contact of her lips or tongue. Their eyes met, and the (until now) inexperienced girl proceeded to let loose with gusto, applying everything she had learned thus far without ever once looking away. Luna’s cries, up until now restrained, came out into a shout, massive and quaking as she reached down and ran her hooves through Fluttershy’s mane, bucking her hips against that loving and endlessly caring mouth. Her climax rolled into a second, unceasing and just as strong as the first, until finally she managed to calm herself, Fluttershy cleaning up and slowly cooling down.

“Oh sweet mercy... That... That...”

“That was the, um... Royal Canterlot Bedroom Voice?”

And now it was her turn to compete in Equestria’s Most Blushing competition, realizing that if anypony in Ponyville had been asleep at this hour, they certainly were not now. She tried to think back and figure out if she had actually cried her lover’s name, or just a guttural sound of release... But then Fluttershy was climbing up the bed towards her, and she realized she had a favor to return.
