Princess Duty

I followed the Princess in lock-step down the long palace corridor leading to her private chambers, acutely aware of the weight of responsibility that had been put upon my shoulders. I couldn't allow any screw-up, any lapse of attention. This was the real thing – what I'd been training for since I joined the Royal Guard.

After eleven years of guarding echoing empty hallways, standing perfectly still as glorified decoration over dignitaries who didn't even seem to see me, and patrolling the palace wall on the lookout for nonexistent enemies, I'd finally been assigned to the post that every Royal Guard aspires to: princess duty. And not just ceremonial princess duty, either. I'd done that before – standing still and looking pretty at formal events where the Princess wanted a visible Guard presence. No, this was the real thing: personal guard to the Princess for the entire duration of my shift.

While my comrades in the barracks had been endlessly elbowing me and making distasteful jokes about how much I'd enjoy the Princess's company, my commander – Lieutenant Ironheart – had hammered the importance of this assignment home to me over and over again. He drilled two simple rules into my head. One: don't fuck this up. Two: never leave the Princess's side under any circumstances. I'd promised him repeatedly that I'd do my very best, and I was doing my very best. I'd been performing my duty with the utmost precision all day, and not even the most thorough of performance inspections could have found a single flaw in my bearing, uniform, or the execution of my duties.

And for once, the job of being a Royal Guard wasn't boring. Oh, sure, it still consisted mainly of standing perfectly still and looking officious, but being constantly in Princess Celestia's presence gave even that a good deal of interest. Even the most boring hearings or trade negotiations were livened up by simply being near the shining, effervescent beauty of Princess Celestia.

As I followed her down the hall now, that very beauty was making my job of being vigilant much more difficult. It took an effort of highly trained will to pay attention to anything other than the swinging of the Princess's generous hips beneath the silky, almost-transparent gown that flowed over her like milky, clinging water. And the suggestion of lithe curve that her ass presented on every step forward...

I bit the inside of my cheek, using the pain to keep me focused. None of that now. I was supposed to be assessing possible threats to the Princess, not contemplating the possibilities of her assets.

When we reached the entryway to the Princess's private chambers, I gave a salute to the two guards at her door as I entered behind her. How many times had I been one of those guards; how many times had the Princess passing in or out been the highlight of my entire day because at least something happened?

Inside the Princess's private chambers, it felt like an entirely different world ... or at least an entirely different building. The smooth whitestone walls were replaced by warm-colored sanded wood paneling, further warmed by draperies of yellow and gold silk from the ceiling. Instead of the ostentatious golden furniture with purple cushions, there were worn, comfy-looking couches and a writing desk that looked as old as the Princess was supposed to be, and as well-loved. Rather than the tiny, defensible windows or stained glass masterpieces of the rest of the castle, this room had two huge and absolutely clear windows: one facing east and one facing west, perfectly framing the slowly setting sun. The polished marble floors were still there, but they were covered with rugs from a hundred exotic places I'd never be able to identify. Even the smell was different – the clean lavender scent from the palace hallways gave way to a spicy and bright aroma, as if someone had managed to capture the scent of a spring morning within incense and then used it liberally in the room.

Of course, I didn't have much time to appreciate the décor. The Princess must have seen it thousands of times, and she strode right through without breaking her pace. She was headed toward another door on the other side of the large room. Through that door was the Princess's bedroom.

It gave me a little chill, being in such a private place. No one else other than the servants who cleaned it ever got to see this room, and they were a singularly tight-lipped bunch.

But the Princess didn't stop there, either. Her sweeping gait took her straight across the room to yet another doorway.

Beyond that doorway, I could see clean white tiles and the entrance to a shower beyond. As the Princess went inside, I took up station just outside the door, helmet in hand and standing stiffly at attention.

The sound of rustling cloth came from inside, and I tried to distract myself by taking in the sight of the Princess's bedroom rather than allowing myself to daydream about the now-nude demigoddess only one doorless entryway apart from me. The bedroom was just as homey and warm as the outer room had been. A multitude of white and gold gowns hung in the wardrobe across from me, behind a bed that looked like it belonged in a farmhouse rather than a princess's bedchambers – its plushly stuffed quilts did look supremely comfortable, though. Just along the wall next to me was a surprisingly messy vanity, with makeup supplies strewn all over the—

“Guard – where are you?”

I turned toward the doorway, then immediately slammed myself back against the wall as I saw the Princess in nothing but a pale blue towel. I stared steadfastly out into the bedroom, but nothing could prevent that brief glimpse of Princess Celestia's barely-covered body from burning itself into my memory. I felt my face heating with an intense blush, but I forced myself to maintain my bearing otherwise. “I am here, Princess.”

“And why have you abandoned your post?”

“I...” My mind raced. Ironheart's 'Rule One' ran through my head over and over again. “I'm still, here, Ma'am.”

She came closer to me – even though I wasn't looking at her, there was a warm, close feeling in the air of her drawing near. When she spoke again, it was scarcely a whisper. “Were you not ordered to stay by my side under all circumstances?”

“Y-yes Ma'am. But...”

“All circumstances.”

I took a deep breath, trying to steady myself. This couldn't possibly mean what she seemed to be implying. “Yes Ma'am.”

“And what part of 'all circumstances' makes you think you can abandon my side while I'm in the shower?”

“I...” There was nothing. How could I possibly argue with that? She was absolutely right about my orders, and besides, all Royal Guards in the Day Division answered to her. Even if it was against the orders given to me by Ironheart, any request directly from her would override those orders. I turned to face her, locking my eyes onto her face to prevent them from wandering elsewhere. “My apologies, Ma'am. It won't happen again.”

She smiled. “Perfect. Now come along, please.”

When she turned, clearly expecting me to follow, I couldn't help but look down. That towel didn't come down nearly far enough to truly cover her, and the perfect curves of two gorgeous ass cheeks peeked out from underneath. My eyes went wide, greedily drinking it in. There was no stopping myself this time. The Princess's backside, both plump and pert, was a view so legendary no one could ignore it.

Of course the worst possible thing happened. She turned around. She turned around and caught me staring. And even as she stared back at me, her hands on her ample hips, I couldn't stop myself. There was no way to tear my eyes away from her deep cleavage, the impressive swelling of her bust underneath the towel, or the way her legs seemed to extend endlessly up into the towel's teasing lower hem.

Rather than the stern rebuke and immediate dismissal I expected, though, she said something entirely different: “You're not going to come into the shower wearing your armor, are you? You'll get it all rusty.”

“Oh, uh...” I glanced down at myself – the first time I'd been able to tear my eyes away from her body for even a moment. “Of course not.”

I made quick work of unlacing my chest plate, and shrugging off my mail, then set aside my gauntlets alongside them on a worn wooden bench conveniently next to the glass shower stall. That left me in just my semi-ceremonial under-tunic and my boots.

Princess Celestia leaned against the golden pillar of the shower door with nonchalant disregard for the way the towel was beginning to slip a bit lower over one breast. She raised one eyebrow at me.

That was all that was needed. She didn't need to say anything. I already knew it would be ridiculous to get in the shower with even this much clothing on. So, moving rigidly and robotically, I turned toward the bench and removed the tunic as well. Removed every last stitch of clothing on me. As long as I didn't think about it and just went through the mechanical motions, I could manage it. If I allowed myself to think of it as getting completely naked in front of the Princess, I wouldn’t have been able to finish. I would have died of embarrassment first.

I was making sure to face away from her as I took off the very last bit, even though that left me unthinkably bare-assed in front of the ruler of all Equestria.

“Not bad,” the Princess said. It sounded like she was right behind me, right over my shoulder. How had she gotten so close so silently? “Most of the time I get a new guard, it takes me weeks to get him this far.”

Wait – had I been too forward? Too compliant? But I'd just been following my orders to the best of my ability!

“Now ... let's see what we're dealing with...” She laid a hand on my shoulder – on my bare shoulder! – and began turning me around. I was powerless to resist.

As nervous as I felt, I expected to see something horrifying. I expected a lecherous and predatory hunger, or a cold and stern rebuke, or even a calculated assessment as if from a Royal Guard inspector. I wasn't prepared for what I saw, though. She gave me a warm and inviting little smile, and the look in her amethyst eyes was of playful invitation, nothing near as sinister as I'd been expecting.

Still, though, she didn't make it easy to get over the nervousness I'd been building up. She looked down at the reason I'd been facing the wall, and her smile grew. “Oh my... Already standing at attention, are we?” The Princess reached down and blatantly grabbed hold of my cock, making me gasp at the unexpected contact. Reaching downward made her towel slip a bit farther, beginning to show just a hint of round pink areola crowning the alluring roundness of her left breast. “Why, you haven't been sneaking illicit glances at the very princess you're supposed to be protecting, now have you?”

My eyes darted between her beguiling eyes, her nearly-exposed breasts, and her hand – her soft, slender hand touching my cock! I didn't know where to look, how to respond. All I could do was to stand rigidly in place as the Princess's thumb massaged slow circles along the sensitive underside of my cock.

Her other hand traced a line of tingling alertness down my chest with her fingertips. “Is something the matter?” she asked.

“N-no, Ma'am.” As unprecedented, impossible, and incomprehensible as this was, the one thing I was sure about – in a very primitive and difficult-to-confuse part of my mind – was that I did not want this to end.

She smiled at me again, a deep, knowing smile that sent warmth right through me. “Well, it certainly seems that you're ready for a shower now. Come along.”

The Princess let go of my cock as she turned to get in the shower, and I was once again mesmerized by the cheeks of her ass peeking out from under the towel. But that was only momentary. By the time I took my first step to follow her, she'd unfurled the towel from around herself and was reaching up to hang it on the outside of the shower stall. My jaw would have dropped if I hadn’t already been staring slack-jawed. There she was, Princess Celestia, completely naked, right there in front of me. My unbelieving eyes traced up from her thick, curvy legs, over the perfect round cheeks of her ass, and up her long, smooth back, all the way up to her gorgeously sparkling hair. With her arms over her head like that, there was a hint of her breasts visible on either side of her ... and they jiggled ever so enticingly as she moved.

It only lasted for a moment. Then she had her arms by her side again ... and then she was inside the shower stall, with the frosted glass blocking my view.

I made haste to follow her, almost tripping over myself in my rush to restore my view of the Princess. As I stepped in, the shower hissed to life. I winced away, but the overspray that splattered onto me was pleasantly warm ... the perfect temperature. Blinking my eyes back open, I fervently wished that the barracks showers had such a luxurious feature.

But when I saw her, any thoughts of shower equipment dropped out of my head as if the threads holding them up had snapped. If I'd thought the back of her had been mesmerizing...

She stood a little crookedly, with a rakish tilt to her hips and with her arms crossed underneath her abundant breasts, which spilled out over them. She held her mouth in a little quirk of amusement, and the water plastered her normally waving hair tightly down over her shoulder. Without requiring any conscious notion to draw them, my eyes slid down her body, over her incredible breasts and their bright pink nipples, over her surprisingly toned belly, and down to ... to... I gulped, and I was so far gone that I accidentally mouthed the words as they filled my brain to the brim: 'Princess pussy.'

Princess Celestia giggled. “I take it you like what you see?”

The only response to her question that I could manage was a dumb, slow nod. Her pussy lips were pert and perfectly smooth, adorned only by a colorful little patch of hairs above, neatly trimmed into a sunburst shape. Her pussy looked almost too small for her, framed as it was by her thick thighs and wide hips.

The Princess's smile grew – something I felt like sunbeams on my bare skin more than I saw, since my eyes were locked on something quite a bit lower. She took a step closer. “Maybe you'd like to get a closer look?”

Another dumb nod. I stood planted on the spot, blatantly staring at what I'd never expected to have so much as a tiny glimpse of. Before today, the thought of Princess Celestia as a woman it was actually possible to have sex with had never entered into my mind. Now, it was all I could possibly think about.

The warm glow of her smile faded. “Well?”

If anything, that only froze me even more firmly in place. Oh no! What had I done wrong? I was screwing it up, just like I should have known that I would!

She rolled her eyes a little. “Oh dear me... I'd forgotten how uptight new guards could be.” A single stride of her long legs closed the scant distance between us until her protruding nipples very nearly touched my chest. “It seems I'll have to spell it out for you. Kneel, guard.”

Years of training and drills broke through to a part of my mind that was still functioning – that was an order from the Princess! Instantly, I dropped to one knee in front of her.

Thanks to her superior height, even just being on one knee put me quite nearly at eye level with the untouchable mystery of the Princess's pussy lips. Even my shock-frozen mind was beginning to get the idea of what she intended. But with understanding also came denial. She couldn't possibly want me to do that. She was a princess. She was the Princess! She simply didn't do this kind of thing! It wasn't possible! Everything in me knew it wasn't even remotely possible.

But a force outside of me was about to realign my perceptions of what was possible after all. Princess Celestia's hand touched the top of my head, and with only the light pressure of her fingertips, she guided me forward, closer and closer.

I barely managed to force myself to actually kiss, rather than simply smash my nose against her when the moment came. One moment, I was a Royal Guard and thought I knew my place in the world; the next moment, my lips were pressed against a soft, divine, and incomparably warm pussy.

Instinct took over. The Royal Guard uniform was a magnet for a certain type of Canterlot girls, and I was hardly inexperienced. I'd just never expected to be sharing such an experience with Princess Celestia. Starting gently, I kissed and nuzzled her outer lips, roaming wide – all the way from licking the shower spray off of her inner thighs to tracing just below the underside of her lovely little sun design. But that didn't last long. From her heavy, impatient breaths and from the slight bead of non-shower moisture between her pussy lips, I knew she was more than ready to move to something much closer.

My first lick slowly traced the entire length of her slit, gathering up her nectar all the way up until I brushed slightly against the little nub of her clit.

The Princess gasped sharply, and I knew I'd gone there a bit too fast ... but from the way she still held my head in place, I knew she wasn't entirely displeased.

Now that I'd gotten a feel for her limits, I employed all the skill I had, licking her lasciviously as I held her pussy lips open with one hand, the other gripped around her thigh for support. Her juices flowed freely, as did her rising moans.

The sounds of pleasure in her voice grew and grew, but never quite hit the peak I knew she must be yearning for. Most girls I'd done this with would already be writhing and clawing at the bedsheets by now, but it seemed that the Princess needed a little bit more.

And I was happy to give it to her. Making sure to coat it liberally with her slick juices, I slipped a finger inside her and gently rubbed the front of her inner walls as if trying to call her closer. At the same time, I abandoned brutishly licking – instead, I pulled the Princess's clit between my lips and began gently suckling her.

It only took a few moments. Quite suddenly, with only a deep, shuddering gasp for warning, Princess Celestia's grip on my head shifted from gentle to intense. She mashed my face against her clit as she cried out. Her pussy convulsed around my finger, the warm, slick gooiness of her girlcum flowing down over my hand.

She held me like that for a long moment as her legs trembled and she struggled to even breathe. I rode it out with her, almost feeling as if the orgasm I'd given her was mine as well. To have done this for the Princess filled me with almost as much pleasure as she was moaning her way through. Almost.

Finally, the Princess slumped against the glass wall of the shower, releasing my head and letting me catch my own breath. Her bare chest heaved up and down as she gasped in and out, and I couldn’t look at anything other than the rhythmic swelling of her breasts.

When I finally managed to tear my gaze away from that, Princess Celestia looked me straight in the eyes. She looked a bit disheveled now, her long multi-hued hair clinging to her wet body, but the look in her eyes showed me a deep well of satisfaction. “Not bad,” she said.

My eyes drifted back down to her breasts. I'd never seen a pair this large and yet still so perky and perfect in every way. Surely they couldn't be real ... could they?

She must have noticed exactly where I was looking. “Would you like to touch them?”

My breath caught in my throat.

“I would enjoy it if you did...”

That was all it took. My hands surged toward her as if all on their own, and she pushed herself away from the shower wall to meet me halfway.

Her boobs were real. Unmistakeably real. So soft and plush, melting into my hands as the warm shower spray trailed down their generous curves in hot rivulets. The Princess moaned a little as I pressed them up and together, and she bit her lip slightly as my thumbs rubbed circles around her big, proud nipples. Each one of her breasts would have been more than enough to fill up both my hands on its own. Together, they were overwhelming, and my hands busily caressed her, trying to explore every inch of their alluring roundness.

The Princess's hands weren't idle, either. She reached down and cradled my cock between both of her hands. “Mmm... Very nice. It would be a shame if it went to waste.”

My hands paused where they were, cupping the undersides of her impressively massive royal tits. “P-princess? What do you mean?”

“Still slow on the uptake, hm?” She grinned. “Let's see if this gives you any ideas...” In one fluid motion, she spun around to face away from me, her legs spread out and her hands braced against the thick shower glass. Her water-soaked hair covered most of her back, but it didn't hide the surprising slimness of her waist, and it wasn't long enough to cover the bodacious curves of her ass.

And between those ass cheeks... Once again, her princess pussy completely captivated my attention. I would have thought that after being so closely acquainted mere moments before, it wouldn't fascinate me so much ... but now, with this implicit invitation, those soft, pristine lips were taking on a whole new level of importance.

She looked over her shoulder at me, an impatient fire smoldering in her violet eyes. “Well?”

I was drawn in as if by a magnet ... a really hot magnet. The shower sprayed both me and her at the same time as I came up behind her, holding her waist between my hands. Her back arched downward just a little more, tilting her hips up toward me as my cock nudged its way up between her thighs.

Actually getting inside her – inside Princess Celestia! – wasn't quite so easy, though. The shower had washed away any residual lubrication, and the tip of my cock tended to stick where it pressed against her, rather than sliding in, even when I got it in just the perfect spot.

In the end, I had to take one hand away from her slim waist and use it to wiggle the head of my cock against her slit, teasing out a bit more of her juices, blocking the water from the shower, and guiding myself into just the right spot.

The Princess waited patiently for me to get it in. She knew as well as I did that this was worth waiting for.

Finally, the feeling of wet warmth began to spread over the tip of my cock. I savored the sensation as I slid my length slowly into her with slow back-and-forth thrusts that help spread her juices even more. She shifted her hips side to side, helping sink herself down on me until her ass cheeks pressed up against my thighs.

I paused for a long moment there, just appreciating the divine warmth of her gently squeezing inner walls. This was it. I was having sex – real, actual sex – with Princess Celestia, ruler of Equestria! As impossible as it was, it was happening, right there in front of me ... happening to me.

With a luxuriant roll of her shoulders, the Princess faced the glass wall again. “Tell me when you're close, dear. We wouldn't want any accidents, and birth control can only do so much against the fertility of an immortal.”

I gave her a long, slow thrust. Oh, it would be so tempting to empty myself into her warm depths. I was already so close after all this teasing, and after so much buildup, I could feel that it was going to be a big one... Nothing would be more satisfying than pumping the Princess absolutely full to the brim with my seed.

But no. No. NO! As a Royal Guard, I existed to serve my princess, and I would not go against her wishes on this. Already, I began steeling myself for the inevitable moment when I would have to pull out of her incredible pussy.

For now, though, I could enjoy it. Enjoy her. I leaned close over her back as I thrust inside her again, my free hand reaching around to cup the curve of her hanging, bouncing breast. She moaned again as I picked up my pace, and her deep, silky voice seemed to flow through my whole body, lighting me up from the inside.

Oh – I was so close already! I looked down at where my cock slid in and out of her, at the way her pussy lips stretched outward a little, hugging my cock as I pulled out in preparation for yet another oh-so-satisfying thrust into her royal warmth. I could feel my balls tingling, feel the pressure building. I wanted so much more – so much more time with her, but I knew I didn't dare. There was no way I could hold myself back, not now, not with her.

“Princess!” I forced out through clenched teeth. “I – I'm...”

She yanked herself away from me in an instant, twirling back around and dropping to her knees as the warm water once again hit my cock.

But not for long. Just as my last restraint finally broke, she came to me, her mouth already open and inviting.

The first spurt was a bit too early, missing her mouth and draping thickly over her nose and forehead instead, but by the time the second spurt came, she already had every last inch of my cock in her throat.

I shuddered and moaned as I pumped my extra-large load straight down the Princess's throat. She didn't seem inconvenienced by it in the least, looking up at me with adoring eyes as wave after wave of my spunk gushed into her. It couldn’t be... Could she actually be enjoying even this part? She surely seemed to be at least, and it was driving my body to produce more than I ever had before, which Princess Celestia gulped down hungrily, never breaking eye contact with me.

Finally, though, I was completely spent. I staggered backward, my now-softening cock slipping out of the Princess's mouth. And then it was my turn to lean against the shower wall, panting for breath as my legs trembled and struggled just to hold me up.

Under the spray of the shower, the thick dollop of cum that had landed on the Princess's face slowly dripped downward, plopping down from her nose onto the upper curve of one breast. It stuck there for a few moments before sliding off, trailing down the rest of her body and finally all the way to the shower drain.

Princess Celestia stood up. She was her full regal self again – despite her nudity, despite the little sheen of cum lingering on her face and breast – and unmistakeably the untouchable Princess again. “Quite good for a beginner,” she told me, “though I would have preferred it if you'd lasted long enough to bring me to a second orgasm while inside me. I suggest masturbating thoroughly before your next shift. That should give you a bit more endurance.” Nonchalantly, as if nothing out of the ordinary had happened, she grabbed a shampoo bottle and squirted it into her hand. She wetted herself again in the shower's spray and then began lathering up her hair. “Oh, and feel free to wash up yourself. You'll find the more masculine-scented soaps over in that corner.”

I glanced where she'd pointed. There was indeed a surprising selection for me. More than her own, actually. I wondered for a moment if the palace servants kept them stocked, and if so, what they thought about it.

But as I began cleaning myself – still watching the Princess's luscious body all the while – I began to understand for the first time just why princess duty was so sought-after by the men of the Royal Guard ... and I hoped that I'd be filling this post for a long time to come.
