The train ride to Canterlot has never affected me like this before. Every clack-clack of the wheels below feels like it's ratcheting up the tension in my chest. Even the deep breathing exercises Princess Cadance taught me aren't doing anything to help. I'm just so nervous, and I know I shouldn't be nervous, but I still am, and I hate myself for it, but I can't stop, and...

Deep breath...

I have to pull myself together. I've done this before, I've tested the spell half a dozen times now, and it has worked perfectly every time. I should have nothing to worry about.

But I can't stop worrying. This is Princess Celestia I'm headed toward. If anything goes wrong now, it's going to be...

Deep breath...

I should relax. I want this, I want this more than anything. So why am I so terrified of it? Princess Celestia has been the shining center of my life for almost as long as I can remember. Everything I've done, everything I've become, it all revolves around her. She's the source of everything that's important in my life. She's perfection embodied in pony form, the unattainable role model I'll forever be struggling and failing to become.

For all that we're both princesses now, for all the veneer of equality, both of us know that I am nothing compared to her, I can never measure up to her godlike success and immaculate perfection. She's all I ever needed, and for the most part, all I've ever had.

So, of course, when I first began to feel certain urges as an adolescent filly, the object of my carnal obsessions had been tall, white, and shapely. No, not my brother! Well, only a little. It was Celestia who formed the template in my impressionable teenage mind of just what beauty is. It was only her and always her. She encouraged me to seek out others, but none of them were her.

My invitation to Canterlot, even as it sits back at my correspondence desk in the Friendship Castle in Ponyville, burns a hole in the back of my head. An invitation to private tea with Princess Celestia at six thirty, Wednesday July twenty-sixth. Please R.S.V.P. at your earliest convenience. I still have no idea what prompted such an invitation out of the blue, or what the Princess intends to discuss during our tea. But the invitation to come visit her alone is too perfect an opportunity to miss. Now, I know this is surely something strictly platonic, and probably something mundane ... but there was a time when I would have thought much more of it.

Tone-deaf bookworm that I was back when I was young, I'd been foolish enough to ask her out on a date once. The fact that I actually managed to go through with it – on the fourth attempt – shows just how desperately infatuated I was with her. I wanted it so badly that I forced myself to ask, even though I knew it was a bad idea. The answering laughter from her had sliced me from the inside out, it feels like half of me is still missing, hollow in the middle. When she saw my pain, she nuzzled me tenderly. I enjoyed that, I pretended as ardently as I could that she had said yes, that the touch of her nose to my cheek was the precursor to a kiss ... even though my cheek was already damp with tears. She was not cruel – she did her very best to assuage my broken heart. She explained very carefully how inappropriate it would be for a five-thousand-year-old princess to be in a relationship with her malleable young student.

In the end, I pretended to understand and move on. She was right, even if I didn't want her to be. But I still carry that wound inside me, and I still carry that secret desire.

For years afterward, I would sneak lustful looks at her, easily facilitated by how much taller she was. My image of her body – cobbled together from countless hasty glances – is burned into my mind. If I close my eyes even now, I can see it. I can see her pale pink teats stretching along the bottom of her long, lean belly. I can see the shapely rounded curves of her ass. I can see the pert perfection of her pearly pink pony pussy pouting up at me between her sunny-white cheeks.

I open my eyes. I'm breathing heavily, and not for the sake of stress reduction exercises. I can feel the dampness of the plush seat beneath me.

Thankfully, I'm alone in my private rail car. Rank does have its privileges, even if I haven't yet been able to justify an entire private train like the other princesses. Glancing out the window, I can tell that we're still at least ten minutes away from Canterlot. We're only in the foothills so far. If I rush it a little, that will be more than enough time for me to have a much more effective stress reduction exercise.

I use my magic to lock the doors of the train car, and I pull the shades down over all of the windows.

Then I slip my hoof down between my legs. I revel in the feeling of it sliding between the plush, lightly-furred skin of my thighs. The soft bottom of it brushes over my teats, tickling them on its way to its true prize. I have to lean forward and lift my butt off the seat a little in order to fit my hoof down there ... and when I do, I feel just how sopping wet I am.

My goodness, I'm soaked down there. If I'm not careful, I'm going to stain the cushions.

But my hoof feels so good. I quiver, and my fur stands on end. Oh yes, oh yes. I need this. I begin rubbing it in the quick, efficient circles that always get me off the fastest. My nether lips are pulled slightly apart and they slide on the soft inner surface of my hoof. My winking clit kisses me back as I increase my pace.

I close my eyes again, and Celestia's body is there. I've never seen the deeper pink that must be inside her glorious pussy, but as I open myself, I can imagine what it must be like. What if she was as wet as I am now? What if she wanted me? What if she wanted me as much as I want her? Would she call out my name as I slid my tongue between those perfect white lips? I can almost taste her clit as it bulges out into my mouth I want to kiss it, I want to kiss her, I want to rub myself against her pussy and let our juices mingle, let us become one. I want her to call my name in her passion! I shudder and my legs clench around my pulsating hoof. “Oh! Oh Celestia!” I'm close now. I can almost—

The door of the train car clicks open, and I hear my stewardess's voice: “Princess, did you call for—”

All sound ceases as I hurriedly cast the show stopper spell. I open my eyes and look at the door. Good, she hasn't come all the way in yet. She isn't looking at me.

Putting her out of my mind, I return to stroking my needy pussy. In a matter of moments, I'm close again. In the silence, in the stillness, I can hear the faint, wet sounds coming from underneath me. That's what it could sound like when I touch Princess Celestia's forbidden treasure. I can almost hear her deep, smooth voice moaning for me. It mixes with my own moans, unrestrained now that I'm safe in my spell.

With a jolt, I reach my climax. My pussy pulsates madly against my hoof, which I mash up against my bulged clit, heightening and lengthening my much-needed release. “Oh Celestia!” I scream. “Oh yes! Take me! Claim me, I'm yours! ... Aaah!”

After a few moments, I stop shuddering in place, with only a few more twitches as I pull my damp hoof out from between my legs. Clouds of heady pleasure are circling in my brain, they make me a little dizzy, so I lean against the backrest as I catch my breath.

Whew, I really needed that. Now I can look at what's to come with a clear head. Or at least not quite so muddled by doubt, anticipation, and anxiety.

What a mess. And how had the stewardess interrupted me? I thought the doors were locked!

But a quick examination of them showed that I had not locked the doors. I merely turned on the magical noise dampeners installed in each door ... a luxury feature I haven't yet familiarized myself with, and which would explain why the stewardess couldn’t address me from outside the door. Yet, she could still hear me... There are so many unexpected things about being a princess that I'm still only beginning to get up to speed on.

I glance back at the seat I've been masturbating in. A damp splotch covers a dinner-plate sized patch in the middle, and it's still spreading, not to mention the wetness on my own hoof and rump.

Thankfully, my rail car has a fully functional wet bar. With a generous application of towelettes soaked in the sink, and an even greater application of dry ones, I'm able to more-or-less cover up any evidence of what I was doing, save for the lingering smell. Even that, I do my best to cover up, taking a lemon from the bar and spritzing it strategically around.

Only when I've completely finished cleaning up – by hoof and mouth alone, like an earth pony, since I can't use magic while the spell is in effect – do I return to the seat next to the one I was in before. Then I can finally restart time. The only evidence of my stress reduction will be a few soiled towelettes in the bar's wastebasket and a bit of lemon-tinged mare scent lingering in the air. I've probably added half an hour to my subjective travel time ... but it was worth it.

“—any assistance?” The stewardess enters my rail car and looks up at me as if I'm some sort of goddess to her.

There is, of course, a small black flash of resentment, but I quash it. She's a lovely young mare on her first official assignment, and she's dreadfully eager to please. She's just trying to do her best and impress her new princess. I can't stay mad at her – it's not her fault. Since there's nopony else in the car, it's perfectly reasonable to assume that if I called out, it would be for her.

“Do you know how much farther it is until we arrive?” I ask, if only to justify the pretense of calling her in. “Are we going to get to Canterlot station on time?”

She hesitates slightly, but she has good instincts. “I'm not familiar with this route yet, Your Highness, but I can go verify that with the conductor in just a matter of moments.”

“Thank you,” I say with a nod.

Sensing the dismissal, she hurries forward on the train. I know that unless some sort of miracle happens, we'll arrive at the station long before she manages to get that information and return, but bless her for trying. I really should put a good word in for her with the royal head of staff while I'm in Canterlot.

She still hasn't come back yet when the train stops at Canterlot station, two minutes early. The poor mare must be worrying her head off about it. But I'll make it up to her on the way back... Maybe I'll even stop time with her; she is awfully cute, especially when she blushes after getting a compliment.

The important thing for now, though, is that Princess Celestia herself is waiting for me on the platform, surrounded by a small circle of grim-faced guards and a large circle of curious onlookers. It's interesting that she saw fit to come meet me here, and it's a wonderful way to show her true commitment to treating me fully as an equal. Everypony watching will know – whether they consciously realize it or not – that Princess Celestia and Princess Twilight are on equal terms. Even if it is all for show, even if we never can truly be equal, it's heartwarming to see this kind of consideration from her.

When I open the door of my rail car, the crowd spontaneously parts, allowing me access. She watches me and smiles her gentle, glowing smile as I approach through the wonder-struck ponies around me.

Once again, the anticipation is building inside me. But I have to hold it in now. Everypony is watching.

“Welcome, Twilight,” Celestia says as I pass through her circle of guards. “I trust you enjoyed your trip?”

She was the one responsible for the private rail car, of course. She called it a birthday present, and that's no doubt what she's referring to. But I can only think back to how truly enjoyable the ride was, given my little interlude. I bow very slightly, as befitting equals. “It was magnificent, thank you.” She can never know how true that is... Oh, the sight of her! I want her, I want her now! Could I? Do I dare use my spell, right here in front of everypony?

Giving only a slight nod of her head in return, Celestia takes a step toward me. “I'm glad to hear that. Hopefully the unusual invitation hasn't caused you any undue stress?”

Oh, she knows me too well! “No, not at all,” I lie. She can never know the feelings burning through me right now, from the tip of my nose straight through to the heat between my legs. I can't freeze time just yet ... the ponies around us may not notice much, but Celestia is immensely smart and observant. I can't afford to take any risks with her ... it has to be while she's not looking at me, and I have to be extremely careful to remember the position of everything.

“Excellent.” She probably knows I'm lying, but she also knows that publicly calling me out on it, even in the subtlest ways, would devastate me. “Shall we return to the castle? I'm afraid there is a great deal to discuss.”

The train whistle blows, and for one moment, Celestia's gaze leaves me and darts toward the source of the noise. It's my moment! Impulsively, I fire off the time spell.

Everything stops, the train silences in mid-whistle. Princess Celestia is frozen in place right in front of me! I almost faint from the giddy weight of it. I've done it! She's mine, she's finally mine to do with whatever I please!

I have to sit down for a moment and just breathe. Oh my goodness, I really did it!

Something flickers in the corner of my eye. Did Celestia just glance at me?

I shoot up to my feet and stare at her. She doesn't seem to be moving, and she's still looking toward the train's engine. Even her perpetually-waving hair is frozen perfectly in place. She doesn't seem to be breathing.

Still... I've never tested this spell on a fellow alicorn before. What if she's too powerful to be affected by it – could she just be pretending to be frozen? But why would she?

I come up close to her, examining her like a jeweler inspecting a suspect gemstone, searching for even the tiniest flaw in her facade. There's nothing. She seems perfectly frozen, not a single breath or twitch. Her eyes are locked exactly where they should be. I was probably just imagining it – I am very nervous about this, after all. It's not unusual for me to be a bit paranoid. I whip my head back toward her, ready to catch her in the act of moving, but she's still frozen perfectly in place.

Okay, stop worrying. The spell worked, and now you have her.

I have her. I have Princess Celestia in my grasp! It hits me again, and I almost fall down in the dizzy sense of triumph. Now I'll finally be able to touch the sun in all her glory, and I won't get burned.

My eyes stray to Celestia's flank, to the huge sunburst emblazoned on her fur. Now I can touch the sun, literally, if I dare. I lick my lips, unable to look away. She's so beautiful! I can't breathe, but I don't need to. I need to walk toward her, step by shuddering step, and I need to reach my hoof up toward that yellow and gold circle of fire, toward the curvaceous skin underneath it.

I pause, just a hair's breadth away from touching her, from touching my mentor and the secret apex of all my hidden desires. I've never touched her like this before. Can I? Can this really happen?

My heart thunders in my chest a million times a second, and it feels like hours pass between each beat. That tiny space between my hoof and her flawlessly groomed fur stretches into a vast gulf.

And then I touch her.

It's anticlimactic. It's just velvety fur and soft, giving firmness of muscle underneath. It's just another pony, like any other... And it's exploding electric fireworks inside my head. This is Princess Celestia's flank. I'm touching Celestia! I'm touching her! I'm—

I yank my hoof away as if burned by that fiery sunburst. My chest heaves with my panting breaths as I come to terms with it.

I've done it, I've finally done it! I touched her. And nothing bad happened. I could touch her more, I could touch her anywhere I want!

A chill shudder passes through me, and I shoot back to her like I've been pulled in by a super-magnet. I wrap myself around her tall hind leg and rub my face into her glorious flank as my hooves wander over the inside of her thigh. She's so warm! How have I survived so long without feeling this? I can feel the soft veins through the fur on the inside of her thigh, and I kiss her cutie mark as my hooves explore her. Higher and higher, she's so gloriously sexy! Her beautiful muscles are so thick and perfectly curved and... My hoof reaches high enough to brush her little teats. I feel her naked, furless skin, and it's so, so soft! I whimper into her cutie mark and nearly fall off of her.

This is... this is incredible. This is beyond anything I've ever imagined, and yet it's exactly as wonderful as I imagined she would be!

I rub my cheek across the generous curve of her ass, and then I see the base of her tail just above me.

I lick my lips. “Oh, Celestia. I love you. I want you...” I move a little closer. It's impossible for this to be happening. This must be a perverted wet dream. My tail is already flipped over my back, my pussy flowing and winking freely. “Oh Celestia, I'm really going to do it. I'm going to...”

As I round the curve of her ass, my voice catches in my throat. I've begun to see a little sliver of her vulva. As I move, I can see more and more. And then, there it is.

Never in my life have I seen anything more beautiful. Celestia's pussy is immaculate. Perfectly proportioned, perfectly smooth as it bulges out between her well-toned ass cheeks. Her flawless skin is just barely on the pink side of white. She looks like a marble statue made of the perfect mare, a standard of beauty impossible to match in real life ... and yet, there she is.

I realize I'm drooling when I feel a drop trickle down from the corner of my mouth. Blushing furiously, I slurp it back up. It's a good thing that Celestia is frozen, that she can't see me like this. Oh, I'm such a lost cause with her!

And I still can't take my eyes off of the impeccable bulge of her royal vulva.

It's inevitable and impossible that I will touch her. Impossible and inevitable. My hoof is already reaching, already sliding up through the fur of her ass cheek. This time, there's no hesitation. I touch her, and I bask in her glory.

Her plush, warm flesh spreads against the soft inner surface of my hoof, and I shudder. Honeyed pleasure seems to flow down through my hoof and through my whole body. Did I almost orgasm on the spot? Oh, how I want her! I rub her beautiful mound underneath my hoof, taking in every little detail of the sensation. The fur of her ass cheeks on either side, the soft heat of her body from within, I can even feel the way her lips open slightly when I move them.

I need to see it! I need to see her inner passage, her deepest secret. Pushing her tail up and out of the way, I get entirely behind her. I hold her pussy with both hooves, and I spread her open. It's the gates of heaven, shining pink heaven. So pink she's almost red inside. It contrasts so sharply with her pale skin. And she's even ... is she a little bit wet?

What secrets indeed! What was she doing before I came, why would she be wet just from meeting me at the train station?

Surely it's just a seasonal cycle, or a whiff of the burly guards surrounding her, or maybe a hidden thought about a secret lover back in the castle. Surely that can't be for me.

But I want it to be for me. It would be the culmination of every wet dream I've ever had if Princess Celestia herself was hot and bothered for little old me.

Even if it's not for me, I'm going to take it. I'm going to taste it. I lean in, I breathe the enticing perfume of her entrance. My hooves are spreading her open in a diamond-shaped vision of pink bliss. I can see the way her smooth inner walls dive inward as they close back in toward each other, I can see the tiny dark slit between them ... into the depths of the mare who is the utmost center of my life.

My muzzle is almost there. I can almost taste her. My tongue is stretching as far as it can toward her ... and then I taste it. The sweetest candy has nothing on this taste! Her pussy is warm and firm and delicious. I want to touch every inch of her, and I'm rapidly working toward that goal as my tongue explores her hot depths, her springy-soft lips, the generous firm bulge at the bottom that hides her royal clit. I press inward with my tongue, sliding in between that slit in her lips. I'm going to touch that glorious clit!

And then I feel it, the little nub buried safely between her plush lips. It's, it's—

It winks outward, into my mouth.

WHAT? I jump back, falling over myself. I bowl over one of the guards, knocking him down where he lies motionless on the platform. I scream, but I don't hear myself. I'm sure I'm dying. I'm having a heart attack, or maybe a stroke. My heart's not beating. I can't breathe. I'm being crushed under a million tons of shock.

Princess Celestia, her cheeks flushed red, turns around. “I'm sorry, Twilight. I couldn't help myself.”

My mouth is moving on its own, maybe trying to gasp in air, maybe trying to form words. It doesn’t succeed in doing either. The rest of me can't move. It's as if I've been struck by my own immobilizing spell.

“First, allow me to apologize for my little charade. I developed an immunity defense spell against Starswirl's 'show stopper' nearly eight hundred years ago, and it's been in effect ever since. Of course I noticed the periods of frozen time, and as they began to occur more frequently and for longer durations, I had my suspicions about who might be behind it.” With that, she gives me a pointed look. “That is, in fact, exactly what I invited you here to discuss.”

I'm fairly sure that my heart is beating again, that I'm breathing again, if shallowly. I can't feel it, but I think I am. But it doesn't matter. I'm still dead. Princess Celestia is going to kill me now, I'm sure of it.

“I never expected you to use the spell in my presence ... but once you did, I wanted to know why. What would you do with it?” She looks back toward her own flank. “Honestly, I had nearly forgotten your old erotic obsession with me. You've hidden it so well that I thought you'd grown out of it. But after all this time, I'm still the pony you want, aren't I? It's somewhat flattering, actually, even to a pony as accustomed to flattery as I am.”

“Buh ... buh ... buh...” The gears in my head clunk against each other, straining to regain some kind of function.

“Of course, you must know that this is extremely inappropriate. It's immoral. It's illegal – this is sexual assault, not to mention high-degree magical assault. Twilight, what do you have to say for yourself?”

I can only manage a strained squeak, the sound of raw fear leaking out of my head.

“I cannot allow you to continue this. Have you done this to anypony else?”

I don't answer. I can't answer her. But the slight glance to the side, the way my eyes refuse to look at her ... that tells her everything she needs to know.

She shakes her head slowly. “This is very disappointing, Twilight. For some reason, this always happens. Every time I take on an apprentice, they end up abusing the power I've given them. When you ascended and became an alicorn princess yourself, I thought that perhaps I had finally succeeded, finally found a pupil whose heart was pure enough to pass through the temptation of power and come out unscathed. But now, this...” She sighs. “At some point, I have to wonder if I am the one to blame, if it's some flaw within myself that infects every student I teach. In light of that possibility, I am going to be merciful in your punishment.”

Punishment? My heart stops again. She's going to take my wings away! She's going to banish me from Equestria! She's going to lock me into this frozen timeframe and never let me interact with a living pony again!

“Your punishment will consist of two parts. First, you must admit to what you've done and tell each pony you've behaved inappropriately with exactly what you did to them while they were frozen in place. You must tell them this in person, face to face.”

Oh. Oh shit. Though most of my mind is still a train wreck, a small part of me is already dreading what that conversation with Rainbow Dash is going to be like, not to mention Soarin and Spitfire.

“Secondly, you must beg each pony for forgiveness and offer to do absolutely anything to make it up to them. Whatever they decide, you must do it to the absolute best of your efforts. Do you understand?”

That's... That was two parts, wasn't it? Is that really it? Where is the part where she tears off my wings? Where is the part where she has me dragged off to some unexplored wilderness to live among the vicious beasts? Where's the part where she uses my own time magic against me? Can that really be it?

“Twilight, do you understand the terms of your punishment?”

I stare at her blankly, my eyelids quivering. I'm not sure, but I might be drooling again.

“Twilight?”

I nod hastily, then add, “Yes, yes... I understand.”

“Very well. Then why don't you begin with me?”

First, explain and apologize. Second, do anything necessary to make it right. I struggle to regain my breathing. Yes, I can do that. I have to do that. It's so much more merciful than anything I could have hoped for. She doesn't hate me! She just wants me to learn my lesson... I can do this. It's going to be hard, but I can do this.

“Twilight... Stay with me, please.”

Right. First, explain and apologize. “I'm so sorry Princess! I ... I froze time, and while I thought you were frozen, I... I touched you inappropriately! It was wrong and I'm sorry!”

“Be more specific. What exactly did you do?”

I gulp. “I used Starswirl's show stopper spell to stop time around me, and I thought I froze you in place. Then I...”

She looks at me sternly. “Continue.”

“I...” Taking a deep breath, I force myself to say it. “I touched your flank, your cutie mark. And then I came closer and I hugged your thigh. I kissed and nuzzled your cutie mark, and I touched you with my hooves, on the inside of your thigh, and up until I touched...”

“What did you touch?” She takes a step closer to me.

“I touched your mammaries,” I blurt out in a rush. This is making me sick. I want to throw up, but I know I have to continue. “And then I... I...”

“Yes?”

“I went under your tail, and I touched your buttocks, and then I touched...” I choke on the words for a moment, but force myself not to stop. If I stop, I'll never be able to say it. “I touched your ... vulva. And then I spread it open. And then I licked your vaginal opening.”

There! I've said it. I collapse on the ground, a quivering mess. I can feel the dampness of tears on my cheeks, just like when she first rejected me. “Oh, please, Princess! I'm so sorry! It was wrong, and I was stupid. Please, please forgive me!”

When I look up at her with tear-blurred eyes, she's smiling, and she's even closer to me now. Strangely, her cheeks are even more flushed than before.

“Good, good.” Her acknowledgment helps calm me a little. “Now, what are you willing to do to earn my forgiveness? How are you going to make up for this transgression?”

Step two, do anything necessary to make it right. “I'll do anything, Princess. Anything you want. Please, just say it. Anything.”

Her smile grows lopsided, morphing into a sly grin like I've never seen on her face before. “Are you truly prepared to do anything, Twilight?”

I kneel before her and look up pleadingly. “Anything! I just want to make up for what I've done. I'm so sorry!”

Celestia nods approvingly. “Very well. Since you've made me an unwilling subject in your magical experiments, I want you to in turn assist me in testing out a spell of my own, one I've never felt comfortable using with any other pony, but which I have been eager to test for hundreds of years.”

“Of course!” Can it really be so simple? Over the course of my studies, I must have assisted Princess Celestia in thousands of magical experiments. Doing one more should be a breeze. She really is letting me off easy!

“This test may be more strenuous than you're accustomed to. Are you certain you are ready for it?”

“I'll do anything for you, Princess!”

Celestia smiles, takes one last step forward, and kisses me. My eyes pop open wide, and I'm frozen in shock once more as I feel her delicate lips against my own. It's a fairly chaste kiss, but by the time we separate, I'm panting again. What's going on?

Golden light emanates from Celestia's horn. She's using magic of her own! Fascinating ... she's not the one who triggered the time-stopping spell, so she's still able to use magic! But this can't possibly be the extent of the test she mentioned – what else is there?

The light coalesces beneath Celestia's belly. What's going on down there? I can't see very well with her front legs in the way.

Tilting my head to the side, I catch sight of it just as the glow fades. No ... that's impossible! There are two heavy-looking balls dangling between Celestia's hind legs, in the same pale pink as her skin. Just in front of them, I can make out a matching sheath ... the hole in the front of it is immense.

“Do you like it?” Celestia asks.

“You're ... you're...”

“I've given myself a little extra equipment in addition to my lady parts.” Celestia chuckles lightly. Her sheath obscenely bulges, and the pink-white head of her soft cock begins to emerge. “I think you can see now why I've never been able to fully test this spell before. The extent of the scandal would be unthinkable if word of it were to get out.”

“Do you want me to... Are we going to...?”

“Yes, Twilight. To make up for what you've done to me, I want you to help me test the full capacity of this new addition.”

I nod, subconsciously licking my lips. I can't take my eyes off of it. I can't look away from the ponderous balls lurking behind it. They're enormous.

Celestia sees that lick, of course. It shows in the way her cock bulges out just a little more. “Why don't you begin by engaging in some oral intercourse? That should get things started nicely.”

I'm too dazed to reply, and yet I'm stepping forward, my mouth open wide and my tongue sticking out dumbly. Somewhere in the back of my mind, I notice that my tail is flagged up and to the side, and there's a veritable river of juices trickling down my inner thighs. Celestia must be able to smell me already.

It only takes a few long strides to step under her belly, and her cock meets me halfway. It slides out from its sheath, drooping down in front of me as more and more of Celestia's impressive length is revealed. I catch the massive, flat head of it in my mouth. It's so heavy! It's so hot against my tongue! I can taste her musk, and it's nothing like the flavor of her pussy. This is what Celestia would be like as a stallion, and it's what I've always wanted without ever knowing it.

Celestia's cock bends as it grows, pressing hard against my tongue until it pops free. It swings back and forth, and it bumps into my muzzle. The weighty length of it pushes my face aside. But I'm back instantly, licking up her smooth shaft, over her bulky medial ring, across the thick veins at the base. I hold it in my hooves, hugging it against my chest as it begins to swell and stiffen. She's already as long as Soarin was, and much thicker ... and she isn't even fully hard yet!

Swallowing my trepidation along with the taste of her sheath, I nuzzle into her underbelly and become acquainted with her gravid, hanging balls. The twin orbs are firm and tight, with no give as I probe them with my lips and tongue. They're so smooth, so perfect. It reminds me of her vulva, but without the soft acceptance of my touch. Here, there's fullness – a readiness and vitality waiting to emerge. They're heavy with all the energy of an alicorn, with Princess Celestia's new-found lust for me. I plant a sloppy kiss on each one and slowly lick the valley between them. They're swelling, overflowing with a wet gift just for me. I would take one into my mouth, but I can barely stretch my lips around half of one ... and the attention I'm giving her is having effects on the cock I'm holding against my chest.

Her shaft pulses again and again, swelling and hardening each time. It's beginning to nearly lift me up. It's demanding my attention.

So, of course, I comply. I agreed to do anything. I have to take three steps backward before I can see her tip again; I let it bob freely, just in front of my face. I want to take a moment to appreciate the majesty of this thing, to observe the gentle upward curve of it that matches her belly so nicely, to gaze and take the measure of her length and breadth ... but at this point, Celestia seems to be growing a little impatient. She holds my head in place with her magic and thrusts her hips forward.

I willingly open my mouth and accept her shoving the thick head of her cock inside. It slides over my tongue and fills my entire mouth. And I don't begrudge her in the slightest. She deserves everything I can give her, and more.

When her magic releases me, I don't pull away, instead I slobber on her tip and reach up to stroke her shaft with my hooves. I try to pull more of her into my mouth, but I get pathetically little of her into my throat before I begin to gag and cough. I have to pull her out of my mouth, but I press my tongue against her tip, and as my goopy spit leaks out from the abuse of my throat, I lick along the top of her shaft to spread it over her marvelous length. I lick her from top to bottom, all over, over and over again. My dampening hooves stroke up and down as I take her warm tip between my lips again, and I moan as she roughly penetrates my throat.

She's holding me with magic again. I cough and sputter, but she shoves herself deeper inside, violating my throat. I can't breathe and I don't want to. I stare straight ahead, watching her full balls swing back and forth, reveling in the idea that she might empty them into my mouth at any moment. I only wish I'd followed up on that impulse to have Spitfire give me deep-throating lessons ... because I feel like I might pass out soon, and I want to be awake when Celestia gives me her ultimate gift.

But just when I can't take anymore, Celestia pulls her cock out of my mouth completely. I gasp for breath even as I stroke her, even as I rub her glorious wet tip all over my face. I have to extend my hoof all the way out to reach her balls, to cradle them and encourage them to give me their precious cargo.

And then a miracle happens. I feel Celestia's muzzle against my ass cheeks. Her breath tickles me under my tail. And then I feel her tongue on my desperate pussy.

I moan and shove her cock back into my throat willingly. Oh yes! This is so far beyond anything I could ever hope, to have Celestia's perfect mouth tending to my urgent need.

I can't breathe, so I pull off of her and gasp deeply, but only long enough for one breath before I swallow her length again. Pull back, gasp, swallow; pull back, gasp, swallow. I build an obscene rhythm around her girthy cock. And my ultimate reward is hearing a stallion-like grunt from deep in her throat; I feel the vibration of it against my clit. I don't care how much it hurts, I want her inside of me, I want—

I scream, but it ends up just a muffled moan around the huge cock in my throat. My legs almost give out as a massive orgasm runs me over, smashing me down like a surprise tsunami. My juices splatter onto Celestia's face as I throw myself recklessly onto her cock, taking more and more into my spasming body even as the corners of my vision begin to fade. I could die like this and be glad of it ... but Celestia doesn't let me. She steps back and pulls herself out of my mouth. I stare at her bobbing, wet cock as my vision fades in and out. My throat hurts, but it's a vague ache compared to the ultimate pleasure pulsing through my veins.

“Are you all right, Twilight?” Celestia looks down at me with concern. “I must admit, I'm impressed. I didn't expect you to be so skillful. You took it almost down to the medial ring. Tell me, you must have been practicing with someone.”

I shake my head 'no'. Celestia must know that it was only because I want her so badly!

She grins broadly as I catch my breath, and I think she knows. But she stops me with her magic before I can dive back down on her cock. “As pleasurable as this is, I intend to make a full test of this spell's capabilities. Which means...”

Without needing to hear the rest, I spin around and present myself for her. There's no hesitation, no uncertainty. I spread my legs and raise my tail, giving her my wet, winking pussy. I want her to take everything I have.

A slight yelp escapes my lips as she leaps forward and mounts me. She's so fast, so savage! Her hot tip touches my entrance, and I melt into her, pushing back and stretching my desperate pussy lips around the swollen head of her cock. A tiny portion of her slips inside, and my eyes roll back in my head.

“Easy, Twilight,” Celestia whispers in my ear from behind. “While I do want to make a thorough test, I think it would be best for both of us if I pull out in the end. So when I tell you I'm getting close, I want you to get out from under me, turn around, and take my emanation in your mouth. Do you understand?”

“Yes!” I cry out, slipping more of her into my pussy.

“Yes what?” Celestia insists. “What exactly are you going to do? This is a very important safety precaution, so I want to make sure you understand clearly.”

“When you say you're close, I'm going to— Aanh! I'm going to turn around and take it in my... in my... Unnnh!” I quiver and melt as more of her endless length enters me. She's stretching me and filling me with her heat, with her solid, curved firmness. I'm liquifying around her impossible hot hardness.

Either she's overcome by the sensations as well, or my words are enough to satisfy her, because she grabs my hips firmly between her front hooves. I “eep” in fear and hasty anticipation as I feel the muscles in her core bunching up, preparing to—

“Aaah!” I scream out to all the immobile ponies around us as Celestia rams her enormous cock into me. She's splitting me open from the inside, and I love it because that hollow part of me is full now, it's overflowing with her thick white shaft. I want her to use me, I want her to fuck me, I want to be her little purple cock-sleeve, and more than anything – oh, more than anything! – I want her to unleash her heavy balls, empty herself into me. I want to feel the virility of an alicorn princess pouring into me and through me.

Celestia grunts, and her muscles bunch up again. Oh fuck, there's more? Yes there's more! It slides into me and I stretch open around it. I throw my head back against Celestia's chest and scream my pain and joy. I can feel the thick veins at her base flowing over my entrance. Her brimming balls bump into my ass cheeks and my clit is enveloped between them.

I shudder in place. This is... this is...

Celestia pulls back just a little and presses all the way into me again. Fuck! I'm full of her. She's transcended my overworked pussy and touched every molecule of my being!

She whispers into my ear again, “Just look at them, Twilight. All those ponies looking at us, but unable to see. Does it turn you on, seeing them all watching us? Is that why you chose such a public place to use your spell?” Her legs twitch, giving me an extra bump just as my clit winks out to kiss the crease between her balls.

I look at the ponies around us, just like she said. That isn't the reason I chose this place at all ... I was just impatient. But now that I see them... It is hot. Part of me wants them to see me. I want them to see Princess Celestia claim me, to see her make me hers in the most visceral, primitive way possible. I want them to know I belong to her, to know why I belong to her.

Why is this so hot? Why do I—?

Celestia pulls back and slams into me again, making me cry out and lose my thoughts in the wash of pleasure. I push back against her, struggling for even more. More more more more! I can feel her thick shaft pulsing inside of me as my inner walls squeeze against it.

“You could stop your spell. You could show them...” She gives another deep thrust, bucking me forward despite my best efforts to push myself back toward her, then another.

I'm mad with desire. I want it! My horn starts glowing, ready to release the spell. I want all of them to see Celestia fill me! I want them to hear my moans when her thick essence flows into me!

But before I can cancel the spell, Celestia hammers into me. Her balls slap against me, and I lose my spell in the lightning flashes coming from my clit. I can feel her length inside me, every contour and detail! It's—

The light around my horn flickers, and my legs give out. My front legs collapse, and my chest slams down to the ground. I'm shuddering and jerking around her massive cock, held in place only by her hooves on my hips. Even as I spasm around her, my pussy clenching tight and squirting hot juices all over her balls, she doesn't stop. She thrusts into me over and over again, rutting me into the ground.

“T-Twilight, I'm close,” she says through clenched teeth. I can feel the tip of her cock flaring deep inside me, spreading me wide and opening the entrance to my womb.

But my head is still spinning. I'm still reeling with the endless aftershocks of the orgasm she's still giving me. And as appealing at it sounds to taste her thick cum as it streams over my tongue, I want it inside me more. I don't care if she makes me pregnant, I want her to make me pregnant, to make me swell wide with the gift she's giving me. After keeping it secret for my whole life, I want everypony to know: I belong to Celestia!

She groans, and I feel a swell at the base of her cock. The glorious pulse shoots along her length, deeper and deeper inside me, and then it hits. I can feel the powerful jet of cum splatter directly into my womb. I feel the warmth of it spreading through my whole body as the next pulse travels down Celestia's shaft. The next wave bursts in with even more power. I already feel full with it, like I'm sloshing full, but I can still feel her clenching balls against my rump, and they're so very heavy.

“I love you, Celestia!” I cry out as my womb swells with her seed. She's filling me to the brim. I can feel the heat of it spreading up through my pussy as wave after wave gushes into my depths, pushing the rest out to make way for more and more. Hot cream sprays out between my tightly-stretched pussy and the rim of her sheath. The thick, sticky liquid coats my eager clit as it winks up and massages more out of her generous balls. I feel it beginning to run down my back legs and between them over my teats. And, and... “Unh!” I orgasm again, my pussy spraying out a flood of cum and juices that splatters all over Celestia's crotch and my own ass as my inner walls clench down and suckle Celestia's perfect cock.

Only after my own orgasm subsides does Celestia begin to pull herself out of my spent pussy. I must have been too out of it to even notice the end of her climax. The thick length of it slithers out of me bit by bit, making my insides roil around it. My pussy weakly pulses, as if begging for just a little more, even though I could probably never take it.

Her flaccid length pops out of me, releasing a deluge of cum. It swings back once, then forward to slap against my teats, spattering them with another coating of sticky cum. I fall over and lie panting on the ground beneath Celestia.

Even she takes a moment to catch her breath after such a performance.

“Well, that was certainly a very successful test,” she says eventually. “But I'm afraid we failed rather decisively when it came to the matter of avoiding the risk of pregnancy.”

Fearing that words might elude me, I instead just reach out for her front hooves and wrap myself around her warm, golden horseshoes, cuddling against her feet. My pussy is leaking her essence all over my fur, and I love it. I want to bathe in the stuff. I want everypony who ever smells me again to know that I belong to Princess Celestia and none other!

With a sigh, Celestia leans her neck down and nuzzles my cheek. “I forgive you, Twilight. And I would love to do this again with you sometime, if you are willing. But in the interest of avoiding scandal, I do think we should keep our relationship private for the time being.”

I feel warmth spreading over my coat, from the puddle beneath me, through my belly, from Celestia's legs, into my everywhere. I coo and look up at her, and when my muzzle finds a stray dollop of cum, I lick it off of the smooth pavement. It's bland and a little salty, and I want more of it ... but I don't want it bad enough to let go of Celestia's legs.

“Oh, Twilight... I love you, too. I always have.”

My heart does a warm backflip inside me. Yes! I am complete now, whole. I never want this moment to end, and thanks to my ability to freeze time, it never has to end. I can stay like this with her forever...

Celestia sighs again and looks around at the mess we've made. “If we're going to keep this just between us, we're going to have quite a lot of clean-up work to do before you can start time again. Luckily, I'll be able to use my magic, so it shouldn't be too difficult, despite the, ah... volume of evidence to be cleaned. And, of course, I'll need to get rid of this.” Her horn glows again, and her dangling, half-retreated cock vanishes, taking the well-spent balls along with it. Her belly returns to its normal trim and slim self, adorned only by her lovely pinkish teats.

Another aftershock of orgasm hits me, and a glop of thick, heavy cum rolls out from my pussy lips, dribbling down the curve of my ass into the puddle with the rest. My tail twitches, sweeping through the mess and absorbing it greedily.

“Oh dear...” Celestia uses her magic to lift my tail and begin cleaning the goop out of it. “I suppose that rather than spending our private tea time discussing your new-found interest in time-stopping spells, we can instead talk about our options in responding to any possible pregnancy. Not to mention your remaining duty to anypony else you molested while time was stopped. I do hope you're taking this as seriously as I am.”

I look up at her with a dumb, satisfied smile, and I nod. I'm floating in a warm puddle of my lifelong love's cum. I've never felt so perfect and whole. What could possibly go wrong?
