Immortality

Several years and a handful of months later.

Twilight paced nervously outside the room of her teacher, hoof steps barely making a sound against the plush carpet. Occasionally she would stop in front of the door, only to continue pacing, completely forgetting about the bored-looking guard standing nearby. Though the mare in uniform was doing her best to remain professional, she was growing more and more annoyed by Twilight's continued presence.

“What if I’m not immortal at all and this is all some kind of misunderstanding,” Twilight muttered to herself only to scowl and shake her head. “No, all available evidence points to the fact that alicorns are if not immortal, then at least extremely long-lived.”

The youngest alicorn grumbled to herself and continued to pace back and forth in front of the door.

“Even Cadence remarked that she looked forward to seeing the empire grow in the coming centuries,” Twilight whispered. “Though she didn't seem particularly bothered by this for some reason, even though Shining Armor was right there.”

“Speaking of which,” Twilight continued, pausing mid-step. “He didn't seem bothered by this either. Is he truly just accepting of such an eventuality or perhaps there is something else going on.”

“No, that can't be it,” Twilight declared, going back to pacing. “I can't fall into conspiratorial thinking. The evidence so far says that alicorns are immortal, or at least unaging.”

“If that is the case I wonder if I could distill or perhaps capture the part of alicornication that enables the body to continue living, unbothered by age,” Twilight offered, to no one in particular. “Though I would need to corroborate my assumptions first if I am to-”

“You know they are waiting for you, right?” Offered the guard.

“Pardon?” Twilight muttered.

“The princesses got here a half hour ago, which was the time you agreed to for this meeting,” Declared the soldier, gesturing toward the door. “They are both waiting for you.”

“Oh no! Not only am I late, but I’ve wasted both of their time,” Twilight exclaimed, only to frown. “Though if they are unaging then can their time even be wasted in the- hey wait!”

The guard ignored Twilight's annoyance and continued pushing her towards the door, opening it with her magic as she did so.

“Get in there and talk to them before you give me a migraine,” spat the guard before shoving Twilight through the opening and slamming the door shut behind her.

“Well I never,” Twilight muttered with a frown.

“She can be a bit pushy but I find her lack of tact endearing,” Luna remarked.

“Oh! Princess Luna I-” Twilight began.

“Twilight Sparkle, if you bow or call me princess one more time I swear on the moon I am going to give you such a firm talking to,” Luna warned, her voice lowering dangerously while a grin remained firmly on her face.

“I err, sorry,” Twilight murmured, rubbing the back of her neck. “When I’m nervous I can't help it.”

“Well don't just stand there. Come, take a seat,” Celestia encouraged.

Twilight took a moment to take in her new environment and enjoy the calming atmosphere it provided. Where most tea rooms were professional affairs that were suited only for heads of state and various politicians, this one was much more relaxed. Long, chaise lounges, fluffy couches, and plush reclining chairs were surrounded by hundreds of tiny nick nacks, and wallpaper made to resemble rolling hills and endless plains. There were also games and enough tea to feed half the castle staff hidden away in the various nooks and crannies riddling the room. Luna and Celestia had been drinking tea near the largest of the windows, with Celestia sprawling out on an alicorn-sized couch while Luna sat on a rocking chair, sipping tea.

“It's been a while since I’ve been here,” Twilight remarked, making her way to a love seat situated directly across from the two sisters. “I always enjoyed studying here.”

“I’m happy to hear that,” Celestia exclaimed. “My old decorator hated it.”

“She had a talent for making things appear regal, and refined but I’d hate to see her home,” Luna murmured before taking a sip of her drink.

“Oh, it was terrible. Her husband once described their primary residence as an office complex with beds,” Celestia added with a chuckle. “Though I hear that she’s finally begun to soften now that she's retired.”

“Hmm,” Twilight hummed, settling into her seat.

“I doubt you came here purely to reminisce,” Celestia remarked, glancing expectantly at Twilight.

“Oh uh yeah, no I didn't,” Twilight quickly explained. “I actually just had a few questions about well…”

Twilight extended her new wings and gave them a wiggle in emphasis.

“Those are called wings Twilight,” Luna pointed out. “You use them to fly.”

“I knew that much,” Twilight muttered, rolling her eyes.

“I assume you are more curious about the implication of the wings and not the wings themself. Though if the latter is the case, I could recommend a good flight instructor,” Celestia offered.

“No, no,” Twilight hastily retorted, waving her hooves dismissively. “Rainbow Dash has actually been doing a great job teaching me.”

“Truly?” Luna murmured. “I did not believe she would have the patience.”

“Ever since she took it upon herself to teach Scootaloo she’s slowed down a bit, at least when it comes to teaching anyway,” Twilight replied. “I doubt she would slow down in other departments until well…”

“And thus we come to the true reason you are here,” Celestia added. “You worry about them growing old while you remain young.”

“Y-yeah,” Twilight murmured, sinking into the couch. “I can't help but think about watching my friends, and brother pass away while I… don't.”

“I wouldn't worry about your brother,” Luna exclaimed with a small, knowing chuckle.

“Huh? What do you mean?” Twilight pressed.

“We’ll get to that in a moment,” Celestia interrupted, shooting her sister a brief glare. “For the moment we should discuss your own immortality, or lack thereof.”

Twilight opened her mouth to speak.

“What my sister is saying, is that you are not immortal, or unaging for that matter,” Luna quickly added. “At least not yet anyway.”

“Not yet?” Twilight murmured in shock.

“Yes there is one final piece of the puzzle so to speak that you have yet to fit into place,” Celestia stated.

“Do I simply need more time to grow into them so to speak?” Twilight asked, only to glance down and tap her chin. “Or perhaps there is some extra feat required to complete the transformation. I don't have to go through some kind of molting phase do I?”

“Ha, no!” Luna exclaimed, the mare barely able to hold back her laughter. “Though your scalp is going to become really itchy should your hair start to flow like, my sister and I’s.”

“That won't be for a while though,” Celestia dismissed. “Probably ten, twenty years at the most though you’ve surprised me plenty in the past.”

“I don't get it. What do I need to do to become immortal?” Twilight inquired, only to frown. “If that’s something I actually want, anyway.”

The two sisters exchanged a look before nodding to one another. Luna stood up and made her way over to the unlit fireplace while Celestia walked over to the seated Twilight.

“Why don't we continue this conversation in my room, hmm?” Celestia offered, hoof extended.

“I uh, okay,” Twilight all but whispered, a blush spreading across her face.

Twilight took the offered hoof and was lifted gently from her seat, joining Celestia as they walked over to Luna. Who was inspecting the brickwork, only to grin suddenly and press one of the stones, seemingly at random. The ever-inquisitive Twilight was about to ask another question when the fireplace suddenly lifted into the ceiling.

“A secret passage, so that's how you always snuck up on me when I was studying,” Twilight murmured.

“I’m surprised you never figured it out,” Celestia teased.

“You know what I’m like when I’m focused on something,” Twilight replied with an awkward chuckle.

“That I do,” Celestia exclaimed.

Luna was first through the opening, with Celestia alongside Twilight right behind her. Sure enough, they entered Celestia’s private abode. Once through, Luna tugged on a book, and a shelf filled with various tomes fell from the ceiling, resealing the passageway once more.

“You should have seen how many secret passageways Celestia built into the old castle,” Luna added. “I swear we lost a dozen staff every year down there.”

“They were all found quickly and in one piece, I should add,” Celestia stated firmly.

“Yes, yes. You never did let me install any of the fun traps down there,” Luna muttered, flopping down on the edge of Celestia’s bed with a bitter snort.

Celestia joined her sister a moment later, falling into the bed, and leaving Twilight to stand there staring at the pair.

“So what is it that I need to become immortal?” Twilight pressed.

“Well my faithful student, you will becum immortal as soon as you drink the elixir of life,” Celestia replied simply, her words hitching strangely midway through her sentence, leaving Twilight confused.

The elder alicorns exchanged a teasing grin, the pair eagerly looking forward to a new immortal in their ranks. Not only did they desire the added company through the ages, but both couldn't help but yearn for a new pussy to taste and a new tongue to ride.

“I still think that’s a pretentious name, and as the kids say, cringe,” Luna whispered, leaning towards her sister.

“Oh hush you,” Celestia shot back.

“Wait, so that's it then?” Twilight pressed on, oblivious to the secondary conversation. “I just need to drink some potion and-”

“Elixer,” Celestia corrected.

“Elixer and I’m immortal,” Twilight exclaimed.

“True immortality is impossible, as you may have already guessed,” Luna added hastily.

“Yes, you will become ageless, blessed with perfect health, and possessed of an accelerated healing but you will not become invulnerable or anything on that level,” Celestia explained.

“That makes a bit more sense given what I’ve gathered,” Twilight murmured to herself.

“And you could gift such immortality to your friends as well,” Luna added.

“What?” Twilight shouted. “Really?”

“Oh yes, you could indeed grant them the same agelessness that you will have,” Celestia remarked. “Or really anyone you desire, they need not be a friend or family member.”

“Okay back up, why isn't this more well known? If such a power could be bottled you’d think it would be everywhere by now,” Twilight stated incredulously.

“Let's just say that this elixir is very rare and very difficult for non-alicorns to get ahold of,” Celestia added, with a wide, knowing grin.

Twilight blinked in surprise, her mind whirling with possibilities while her mouth clamped itself shut. While her curiosity ran away with her, Celestia and Luna subtly moved about on the bed until they were resting on their haunches. The pair exchanged knowing, excited looks while shifting from side to side, waiting for what they knew was about to happen.

“I have so many questions,” Twilight exclaimed. “Starting with, where does this elixir come from? What is this mystery source?”

“Why, it's right,” Luna began.

“Here,” Celestia concluded.

Twilight then watched in a mixture of confusion, shock, and horror as the two other alicorns leaned back. Spreading their legs wide, the pair cast aside their tails and showed off their dripping pussies and swollen clits. Their privates revealed and on full display, Twilight could see everything, robbing the mare of her ability to even think.

“What?” Twilight muttered in a flat, neutral tone.

Celestia and Luna exchanged another look before erupting in giggles.

“Though we needn't be quite so dramatic about it, the fact of the matter is that we are the source of this elixir,” Celestia exclaimed.

“Or rather our pussies are,” Luna added, rubbing a hoof over her aching sex.

“Wh-what, really?” Twilight exclaimed, still too shocked to even feel embarrassed.

“Yes, it is through the consumption of our um, vital essence-” Celestia began.

“Cum, it's our cum,” Luna interrupted.

“Yes our cum,” Celestia admitted, rolling her eyes. “Is required if you wish to become ageless, or as close to immortal as you can get without the use of some rather dark magic.”

“Ooooh,” Twilight murmured.

Despite the ridiculousness of the situation, Celestia was using the same authoritative, almost teacherlike tone Twilight was used to. Thus the young alicorn knew that her former mentor was speaking the truth, even if she was being a bit saucier than Twilight was used to. With that realization, Twilight's brain finally came to grips with the situation, and a wide blush spread across her face. Worse still for the now very hot and bothered mare, Luna and Celestia had continued to leave themselves on full display while they spoke.

“I err uh,” Twilight stuttered.

“Should we be more modest, Twilight?” Celestia asked. “We could cover ourselves should you not be enjoying the view.”

“I wouldn't say that I hate it,” Twilight murmured, only to shake her head suddenly. “No, I have more questions.”

“Then ask away,” Luna offered while continuing to rub her hoof around her cunt in a slow, gentle movement.

“What about when Luna was banished before Cadance ascended? What did you do then?” Twilight inquired. “I’m assuming that since it's unlikely to be a one-and-done deal that there would have been some err… logistical issues.”

“Semi-regular application is necessary though it becomes far less necessary over time,” Luna answered.

“Our own sex has the same effect as any other alicorn’s,” Celestia answered, running a feather across her pussy and grinning salaciously. “It's just not nearly as much fun.”

“That and sister dearest has gotten quite good at casting spells that aid her in this rather lewd endeavor,” Luna added, bumping her hip against Celestia.

“Indeed I have,” Celestia picked up, igniting her horn and creating a small circular portal that contained within it a certain plump purple pony pussy dripping with arousal. “Oh my, you certainly have grown up.”

“Quite a prominent clitoris,” Luna remarked, peering at the portal linked directly with Twilight's cunt. “Bravo Twilight.”

“H-hey!” Twilight shouted, her voice tinged with terror and arousal in equal measure.

“What? You are getting to see our fountains so to speak it is only fair we get a look at yours before it fully blooms,” Celestia replied.

“What is with you and these ridiculous names?” Luna whispered.

“Hush, you,” Celestia spat back.

Twilight stood there in stunned silence, her brain short-circuiting at the ridiculous situation she suddenly found herself at the center of. She was wet and burning with arousal and she wasn't the only one either, as by then Celestia and Luna were flooded. Their pussies, still on full display, were literally dripping at this point, the pair clearly even more turned on than Twilight was.

“I can't believe your student was hiding such a truly delectable treat,” Luna exclaimed, the alicorn staring intently at Twilight's engorged clit. “What a delicious little cum button. I cannot wait to feel it twitch upon my tongue.”

“I for one want to see just how it looks after Twilight has…” Celestia giggled. “Cum into her own as an alicorn. After all, we were not always the overflowing sexpots that we are now.”

Twilight blinked, her brain no longer connecting to the rest of her body. Something about two of the hottest mares she had ever known talking so blatantly about fucking her senseless had unmoored her mind. That combined with her own general dislike of social situations until recently and the fact that she had no experience save for a faithful dildo made for a very nonfunctional Twilight.

“It seems as though we have shocked poor Twilight into a stupor,” Luna remarked with a smirk. “Let us see if we may rouse her.”

The dark alicorn summoned a mote of buzzing energy and levitated it through the portal and directly against Twilight's clit. The younger mare released a startled whinny before all but falling forward, her hooves guided by the puppetmaster that was Luna. With only the careful application of pleasure, Luna was able to guide her partner into landing face-first into her cunt.

One moment Twilight had been standing there, too dazed to utter a sound, her brain sparking like a damaged generator. The next she was muzzle deep in Luna’s pussy, the elder alicorn’s clit pressed against her tongue. The flavor was strangely intense, and as the liquid arousal coated the inside of her mouth Twilight felt a bolt of lightning travel down her spine. Her brain stopped misfiring, and an intense need filled the mare, prompting Twilight to lean forward and- get pulled away at the last second.

“Ah ah ah,” Celestia exclaimed. “Twilight is my student and I would be remiss to let someone else teach her how to make an alicorn cover her face in cum.”

“And it was just starting to get good too,” Luna muttered bitterly.

“You will get your own turn in time,” Celestia declared. “But for now, Twilight is mine. Isn't that right Twilight?”

“Yes ma’am,” Twilight muttered dutifully, the young mare bobbing her head in excitement.

“Good,” Celestia began, pulling in Twilight's head until their lips nearly met. “Now, do you remember your anatomy lesson?”

“Talk about a mood killer,” Luna muttered, snickering to herself.

“Yes, labia, vagina, anus, urethral opening, clitoris, etc,” Twilight replied dutifully.

“Perhaps I should have made that class more intimate, you did have a habit of getting distracted whenever I broke out the anatomy textbook,” Celestia teased.

“I wouldn't have been bored,” Twilight murmured, her gaze still fixed on Celestia’s dripping folds.

“Now normally I would advise that you take your time, start with some gentle kisses and the like but as you can see that's not exactly required,” Celestia exclaimed with a chuckle.

“No need to kiss your way down our bodies considering we are both already dripping with arousal,” Luna added huskily.

“Y-yeah,” Twilight whispered absently.

“For now I will teach you a simple, easy-to-learn technique but in time you will learn more,” Celestia declared.

“I’m ready,” Twilight eagerly stated.

“Good, now stick out your tongue, let it fall out of your mouth,” Celestia began, watching as her student exactly as requested. “Let your tongue widen until it resembles a pancake, then I want you to move your head forward until you can taste me.”

Twilight once more obeyed her teacher without so much as a second thought, leaning forward until her tongue was against the bottom of Celestia’s pussy.

“Now drag your head up until you reach the top of my pussy,” Celestia continued.

Twilight licked up Celestia’s cunt, holding her tongue still even though she wanted to do more. The effect was immediate, as Celestia twitched, and her cunt spasmed, treating Twilight to a delectable flavor. A taste which she savored so intensely that she nearly began to move, but held back, glancing up at Celestia for confirmation.

“Good now move back, and repeat that motion. Slowly at first while you get used to it,” Celestia encouraged. “Mmm just like that.”

Twilight shifted her head down, and licked up again, keeping Celestia’s words firmly in mind as she began to eat out her teacher in earnest. Doubt clouded the young alicorn’s mind, and she couldn't help but wonder if she was doing a good job. Such doubts vanished quickly as almost immediately after she began, Twilight could hear the sound of moaning coming from above her. Glancing up confirmed that Celestia was indeed the one who gave voice to such pleasure, the elder alicorn shuddering in delight.

“Yes, perfect,” Celestia purred. “Keep your tongue nice and relaxed. Just like that.”

“She picked up on that one quite quickly,” Luna remarked.

Pride stirred in Twilight's chest, as well as a fair number of other, strange feelings. Guilt born out of a feeling that she was somehow staining her relationship with Celestia was easily banished. She wanted this, Celestia wanted this, and though there was an age difference, there was no longer a power imbalance.

They were equals and lovers now.

Worry was a harder feeling to cast aside, but Luna’s remark and Celestia’s moaning did much to discredit that emotion. Though Twilight remained concerned that she was unworthy to be the lover of her fellow princesses, she had been dealing with imposter syndrome her whole life. Thus with the majority of the negative emotions at least somewhat dealt with, Twilight was finally able to focus.

Focus on the mare writhing against her tongue, on the new flavors assaulting her brain and the new sensations coursing up her spine. This was really happening, she was eating out her teacher, and oldest crush while her newest crush watched while playing with herself. It was enough to make Twilight's brain short circuit yet it was her intense need to please that kept her at least mostly grounded.

“You’re doing so good,” Celestia murmured. “Apply just a little more pressure and-”

Celestia shuddered suddenly, her pussy quivering while her cunt spasmed. For a moment Twilight worried she had done something wrong, then she felt hot mare cum splash against her face. She sat there too stunned to move while her teacher slowly covered her face in girl jizz.

“Ffuck that felt good,” Celestia remarked.

“Normally she wouldn't be quite so easy,” Luna added, running her hoof down the interior of Celestia’s thigh. “But this naughty girl has been practically edging from the moment she got your letter.”

“Don't stop now. Most mares can go for at least a few rounds and we alicorns have far greater endurance,” Celestia encouraged.

Twilight dutifully got back to work, repeating the now familiar motion of dragging her tongue across Celestia’s dripping folds. Then she’d pull back slightly, duck down, and begin again, applying just enough pleasure to ensure they remained connected no matter how hard Celestia twitched.

“I think we should make things a little more interesting,” Luna remarked aloud.

Twilight's curiosity lasted only a moment before Luna answered the unspoken question of what she meant by that. That answer came in the form of a certain still active portal moving close enough to Luna’s lips that she could lean forward and plant a kiss on Twilight's clit. The sudden shock of pleasure made Twilight's head jerk suddenly though she quickly regained her composure.

“Focus Twilight,” Celestia teased. “The test remains ongoing.”

Though Twilight kept on licking and following Celestia’s instructions, she couldn't help but become increasingly distracted. Luna kept on attacking her clit, rubbing it with a hoof, or making it vibrate with a bit of magic. It felt good, and soon Twilight could sense an orgasm was rising within her.

“Ah ah ah, focus Twilight,” Luna murmured, withdrawing both her hoof and magic.

The pleasure faded quickly until it fell into the background, only to for Luna to continue her attack. Twilight didn't know how Luna knew when she was close, but it didn't matter, as Luna had made it clear that she would not allow Twilight to finish. This was even as the young alicorn became increasingly horny, her body yearning for an end forever out of reach.

“You really do have the largest, most reactive little cum button that I have ever seen,” Luna remarked aloud. “I just want to see how many times I have to push it before you absolutely cum undone all over my hoof.”

In her need, Twilight slipped one of her forehooves down between her legs and towards her aching pussy. She very nearly reached her target but was ultimately intercepted by a firm magical aura originating from Luna’s horn. Then, with the same inexorable firmness typically associated with industrial equipment uses her magic to return Twilight’s hoof to Celestia’s upper thigh while also gently pushing Twilight’s muzzle against Celestia’s pussy.

“No...no keep your hooves by my sister’s sex and away from your pussy,” Luna exclaimed. “A good student is attentive to her teacher after all. You just concentrate on what my sister is teaching you, and let me worry about your hot, wet cunt.”

“You wouldn't want to get a failing grade after such ah, oh, wonderful initial showing. Would you?” Celestia murmured, shuddering delight when she felt her student’s tongue brush across her engorged clit.

Twilight licked a few more times before her desperation finally overwhelmed her and she pulled away.

“Luna please, I need to cum,” Twilight panted, face covered in mare juice, and with alicorn cum dripping from her lips. “I can't take it anymore. Please stop teasing me and let me c-”

“Shush now Twilight,” Celestia interrupted, grabbing the younger alicorn’s head in her magic and shoving her muzzle into Celestia’s dripping pussy. “You have better things to be doing with your tongue than waggling it uselessly. You have a technique to master you know.”

“Listen to your teacher Twilight. You wouldn't wish to fail now would you?” Luna teased, her magic gently tweaking the younger alicorn’s love button.

“Mmph mmph,” Twilight murmured into Celestia’s pussy.

Returning her focus to Celestia, and Celestia alone, Twilight poured herself into the act. She moved both forehooves to under Celestia’s thighs, and leaned forward, putting a bit more weight into her licks. Up and down she went, ignoring as best as she could, Luna teasing, and her own burning desire to cum as well.

“Yes, that's right. Just a little more!” Celestia exclaimed.

Channeling her need into devotion, Twilight moved faster, licked harder, and did everything she could to bring her teacher to a powerful orgasm. An orgasm that arrived only moments later, the elder alicorn crying out in joy before erupting all over Twilight's face. This time Twilight continued to move, licking away even as her fur dampened to the point that it was sopping wet.

“This is a much better use of your ah, tongue, isn't it?” Celestia teased, shifting from side to side as she rode out her orgasm. “Worshipping my pussy and getting familiar with my taste will become useful skills. Especially when you start doing the same for Luna and Cadance.”

“I should warn you, however,” Luna began. “I am a much harsher grader than my sister.”

Despite the somewhat menacing overtones from Luna, Twilight couldn't help but be thrilled by the implications of Celestia’s remark. It had been rather obvious that she would lie with Luna next, but to have that confirmed was exhilarating, almost as much so as the hint that Cadance was next. Though she felt a bit guilty thinking about her brother’s wife in such a manner, Twilight couldn't help but wonder what the other alicorn tasted like.

Finally, Celestia’s orgasm died, and no more mare cum covered Twilight's now sopping wet face.

“Mmm, that was amazing,” Celestia murmured. “But now it's my turn.”

Twilight barely managed to pull herself out of her teacher’s cunt before she felt herself become airborne. Suddenly Twilight found herself lying on the bed, limbs splayed in all directions, Celestia’s magic holding her down.

“You look good like that,” Celestia remarked, trailing a hoof down Twilight's chest. “Defenceless, with your cute little pussy out in the open for all to see.”

“She looks like she’d make a good seat,” Luna added with a smirk.

“Yes. Do whatever you want to me, princesses,” Twilight muttered.

“I’m going to let that one slip because it kind of turned me on,” Celestia replied.

“Friend in the streets, princess in the sheets. Yeah, that sounds like you Celestia,” Luna teased.

“You are killing the mood sister,” Celestia retorted. “Now, where was I? Oh yes.”

Celestia leaned in close, sliding between Twilight's back legs and hovering over the other mare’s aching sex.

“Mmm you look delectable, my faithful student,” Celestia whispered huskily. “I can't wait to taste purple alicorn pussy. After all, I’ve had all the others. I really must complete the set so to speak.”

“And now that my sister is no longer acting as though she is part dragon and hoarding you all to herself, I shall partake of your newly educated tongue. We must be sure that you were suitably attentive to my sister’s lessons of course,” Luna exclaimed.

Twilight was about to ask what Luna meant when her question was answered before it could be uttered. Luna, rising up onto her hooves once more, stepped astride Twilight's head, looming over the smaller mare. The view was beyond compare, and Twilight stared up in wide wonder as the moon descended upon her, blocking out the light.

“Mmm perfect,” Luna murmured, seating herself comfortably on Twilight's face. “Just as predicted, you make for an excellent seat.”

“Thank you for your assistance earlier, Luna,” Celestia remarked. “You did an excellent job keeping her so focused but not letting her cum. I did ever so want to be the first to feel her cum.”

“It is no trouble at all sister. Please, enjoy her pretty purple pussy to your heart’s content,” Luna invited, gesturing down to the Twilight's aching, blood engorged pussy.

“Mmm, what better way to feel a tight little filly cum than with your tongue in her cunt, and your lips around her clit?” Celestia whispered quietly to herself.

Twilight was just about to get to work on Luna when Celestia interrupted her train of thought. No, Celestia didn't just interrupt Twilight's thinking, she blew up the train, destroyed the tracks, and rent the land asunder. Diving into Twilight's cunt like a mare possessed, Celestia all but devoured her former student’s pussy.

In an instant, it was immediately apparent that Celestia was a master the likes of which Twilight had little hope of emulating. The elder alicorn’s expertise was beyond Twilight's understanding, and she did things with her tongue that Twilight could scarcely even describe. Within only a few short, confused seconds, Twilight could feel her orgasm begin to rise from deep down inside of herself.

Celestia sucked, licked, and twisted her tongue into knots, unlocking pleasure centers Twilight didn't even know existed. Though she used more techniques than Twilight had even thought possible, Celestia was able to effortlessly switch between them. Like a symphony played by only one pony, Celestia turned her student into an instrument of moaning, twitching ecstasy.

“Oh, Celestia yes!” Twilight screamed while cumming, her voice muffled by Luna’s backside hovering over her face. “I’m cumming, I’m cumming, I’m-”

“Yes yes,” Luna interrupted, dropping her butt onto Twilight's face and pressing her cunt against Twilight's muzzle. “We can all see your hot little cunt squirt its cum all over my sister’s face.”

Twilight could barely contain her arousal at such a statement. She could feel her body produce more mare cum than she thought it possible to do so. All of which erupted out of her directly onto Celestia’s face, matting her fur and covering her in Twilight's smell. Celestia didn't seem to mind, in fact, she enjoyed the feeling and moaned into Twilight's pussy all while she continued to devour the smaller mare.

“Now put that tongue to work so that I can cum too,” Luna concluded, rubbing her pussy gently, yet firmly against Twilight's lips.

As Luna rode Twilight's face, forcing her to eat her out, Twilight herself was gathering her bearings. She knew that it would be hard to get enough of her thoughts in order to do even a halfway decent job but she was going to try anyway. If nothing else she would do her best, and hopefully not disappoint the mare currently deciding whether or not she could breathe any time soon.

Using the so-called pancake method wasn't easy, and required a bit of modification, but that wasn't altogether too hard. Twilight was used to adaptation, and this was nothing more than a pop quiz, she told herself. Sure the pop quiz involved her teacher ravaging her pussy, and eating her out with the intensity of a mare dying of thirst but that didn't matter.

“Mmm not bad,” Luna murmured absently, shifting her weight atop Twilight's face. “We should have done this much sooner.”

Celestia muttered something close to an affirmation, though her words could not be understood in the slightest.

Somehow, that was enough to make Twilight cum a second time, the mare still on the edge of orgasm even after finishing once. Though her body twitched, her muscles contorted and her brain was beginning to misfire, Twilight remained focused. Moving her head and neck as much as she was able, she licked at Luna’s pussy, eager to seek out more of the delicious nectar she had tasted not long ago with Celestia.

Luna tasted different, slightly more bitter, with an ethereal quality that wasn't unlike liquid magic. Twilight struggled to put it into words, though one thing was for certain, it definitely fit Luna perfectly.

“Yes, more!” Luna shouted. “Push your tongue inside me, and do slow circles around my clitoris.”

Twilight did as she was ordered, pressing her lips against Luna’s opening and extending her tongue as far as it could go. It wasn't hard to find the hard little nub, and it was even easier to begin applying the pressure that Luna demanded.

“Harder, don't let up!” Luna pressed.

Twilight was about to follow through only for Celestia to somehow dig even deeper into her pussy. The feeling of pleasure was immense, and already Twilight could feel herself rocketing towards her third orgasm. Despite that she continued to stay focused, ensuring her tongue continued to circle around Luna’s clit, teasing it constantly.

“Perfect!” Luna exclaimed, her body tensing. “Just a little more!”

With an eagerness usually reserved for only the most important of tests, Twilight pushed herself to go faster, harder, and better. Her efforts weren't wasted, as she could feel Luna’s ass twitch on her face, and her pussy clamp down on her tongue. The other mare’s breathey moans may not have been audible to Twilight but the way Luna shuddered told Twilight all she needed to know.

“Yes, yess!” Luna called out.

As Luna came, Celestia broke out all the stops, pushing Twilight to cum for a third time only a few minutes after the last time. Twilight was barely able to keep her tongue in motion she felt so good. Despite it all she continued to slurp away at Luna’s cunt, maintaining her pace even as she lost feeling in her back legs.

The splash of mare cum against her cheeks, and into her mouth brought forth a new wave of strange flavors. Far from unpleasant, they captivated the newly elevated alicorn through her newest partner’s orgasm. Until finally there was no more delectable juice to drink, and her own pleasure was beginning to die down, if only ever so slightly.

“Mmmm wonderful,” Luna purred.

The mare lifted her backside from Twilight's face, allowing the young pony to take her first full breath in what felt like forever. Not only was she free to breathe, but Celestia had pulled back, allowing her a moment without mind-blowing pleasure wracking her brain. Laying there, exhausted but exhilarated, Twilight struggled to imagine life being any better than it was.

“That was a wonderful start, but I want more,” Luna professed.

“You simply must taste her sister, she is delectable,” Celestia purred.

“I will be the judge of that,” Luna retorted.

Luna leaned forward, grabbed Celestia by the shoulders, and pulled her forward into a deep kiss. Twilight watched as the two sisters violently made out, swapping spit, and unswallowed mare cum in equal measure. After several tense, breathless moments, they pulled back, neither panting or in need of air.

“You two make for an excellent blend of flavor,” Luna murmured, touching her lips. “We will have to experiment with this more in the future.”

“How I love a good experiment,” Celestia agreed.

“Before we get to that,” Luna began, climbing down from the bed, and slipping between Twilight's back legs. “I do believe that it is my turn to taste our newest alicorn’s sex. If she’s still up for it that is.”

“She better be, it has barely been an hour since we began,” Celestia added.

“So Twilight, are you feeling up to quenching my thirst with your cum and painting my face with your arousal as you have my sister’s?” Luna pressed.

“Y-yes!” Twilight shouted, eagerly glancing back from Celestia’s matted fur and cum drench face to Luna’s unmarred features. “I mean, yes. Sorry for shouting.”

“You need not worry. I’ll have you screaming again in no time,” Luna exclaimed, leaning in close and planting a kiss on the inside of Twilight's thigh.

“Don't leave her waiting Luna, get in there,” Celestia declared.

Celestia grabbed the back of her sister’s head and shoved it down into Twilight's crotch with a firm shove. Rather than be annoyed, Luna merely moaned, diving straight in without a moment more of a preamble. Only Twilight seemed to be surprised by this course of action, with the mare releasing a startled shriek which quickly turned into a content pur.

Though Luna wasn't nearly as ravenous as Celestia, the other alicorn sister was just as good as her sibling. Her tongue twisted with a dexterity that not even Celestia had possessed, playing Twilight like a delicate instrument. In seconds the young alicorn was lying there in ecstasy, trembling as Luna danced around inside of her flooded pussy.

Luna shifted suddenly, and drew Twilight's engorged clit to her lips, sucking upon it like a lollipop. The sensation was intense, probably too intense for Twilight had she not spent the last hour or so getting her mind blown. Now however she was at least sort of ready, though she still grabbed onto the bed and held onto the pillowtop like she was atop a bucking bull.

“Holy f-ffuck,” Twilight stuttered, eyes rolling into the back of her head.

Twilight's clit popped from Luna’s mouth and the alicorn recoiled, a thoughtful expression on her face.

“Say, we never did find out just how many times I need to play with your hot, twitching little cum button to make you cum,” Luna remarked aloud.

“No, we did not,” Celestia agreed, the white alicorn lying on the bed beside Twilight, lounging like a thoroughly satisfied cat.

“Let's find out, shall we,” Luna declared.

Luna recoiled even further, replacing her tongue with the soft underside of her hoof. The gentle limb touched the tip of Twilight's delicate nub before pressing down and rubbing it in firm circles. After a second or two, Luna pulled away her hoof only to lean forward and give Twilight's pussy a long, pancake-style lick, applying special pressure to the mare’s jutting clit.

“One,” Luna declared aloud.

“Mmmm I wonder how long she’ll last,” Celestia murmured, leaning in close. “I’d say no more than forty. The poor girl has quite the hair-trigger you know.”

“I think you're going to be rather close,” Luna agreed.

Twilight lay there and watched as Luna repeated the same motion from a moment ago. Touch, rub lick, another number added to the count.

It felt good, great even, but where Celestia drove Twilight over the edge in as little time as was possible, this was far more deliberate. The gradual, almost gentle process left Twilight wanting more, her orgasm rising with a steady deliberate tide. Despite knowing that the end was coming, and would arrive soon, Twilight couldn't help but writhe in desperate yearning.

“Feels so good, but it's so slow,” Twilight murmured.

“You cannot rush the scientific method Twilight,” Celestia interrupted. “Here, let me distract you.”

Twilight turned to find that Celestia was leaning toward her former student with expectant lips. Meeting her halfway, Twilight embraced her ex-mentor intimately, kissing her with a passion she had never before summoned. Her dildo had no hope of making her feel half as good as she felt at this moment, and Twilight knew she’d likely never use it again. That was unless it was added to an encounter with one or more of the sisters, who no doubt wouldn't mind the addition of a few toys.

Her hoof was taken into the gentle hold of Celestia, who parted briefly to take a breath before embracing Twilight once more. Their dance continued, as Luna’s own game pressed on, driving Twilight towards the looming specter of her great release. Sure enough, after what felt like an eternity, Twilight could feel it close in and she pulled away from Celestia, though she still held tight to the other mare’s hoof.

“I’m cumming!” Twilight shouted, holding onto Celestia like she were the one stable thing amidst a raging storm.

“Cum for me Twilight, cover my face in your juices,” Luna whispered huskily.

Twilight did just that, erupting harder than ever before, and with enough force to absolutely drench Luna’s features. By the time Twilight was little more than a crumpled heap, Luna had enjoyed several mouthfuls and was now covered from brow to chin in Twilight cum. Rising up until she lay next to the bookish mare, Luna licked her lips and hummed in deep satisfaction.

“It takes thirty-seven licks to get to the center of Twilight,” Luna remarked. “Though I think sister dearest may have tampered slightly with the experiment.”

“That just means we’ll have to do it again,” Celestia shot back.

“Very true,” Luna giggled. “They do say any good experiment worth doing is worth doing twice.”

“Yay, science!” Twilight added, raising a wiggly hoof into the air.

Luna and Celestia exchanged a look before erupting into a fit of giggles.

“Yes Twilight, yay science,” Celestia murmured.

“Though I am curious,” Luna added, her thoughtful look morphing into a salacious grin. “Will it take more or less time for you to finish after you grow into your full power as an alicorn?”

“Well we will certainly have ample opportunity to find out, won’t we sister?” Celestia proclaimed.

“That we will sister,” Luna agreed. “That we will.”
