A Royal Tail

The night shift was the worst for a guard. Not only did you have to stay up when the rest of your friends and family outside of the palace had to sleep, but there was nothing to do. No ponies walked past to talk to, the palace being mostly devoid of any kind of activity. If you were a patrolling guard, like Iron Star, all you did was stare at the same section of hallway all night with your horn lit up, remembering that if you slipped up even a little at this horrifically boring job, an intruder could sneak past you and perform wreak all kinds of havoc.

Of course, not everything went perfectly. Ponies were flawed beings, and every guard on the crew had, at least once, fallen asleep, wandered to chat with a buddy, or slipped away to rub one out while on-duty. Even the captains seemed to know these things happened, but as long as it didn't become a habit and you didn't get caught, no pony really said anything.

So when Iron Star heard hoofsteps beneath his drowsy, closed lids, he knew he was in trouble.

Quickly snapping them open, he realized that the pony in question was behind him, so they likely didn't see him sleeping. He didn't hear the clank of armor, either, so it wasn't a guard who would be more likely to get him in trouble. As long as he pretended like he had stopped his patrol to look at something, he doubted anypony would notice.

The steps were coming closer. He turned his head to see none other than Princess Celestia approaching him.

He was doomed.

"Evening, Iron Star," she nodded toward him with a warm voice and kindly smile. Even this late at night, somehow she looked as radiant as ever.

He reflexively snapped a salute. "Good evening, Your Highness."

She didn't answer him, letting her smile linger politely before continuing on her way. Wherever she was coming from must have been important, but Iron Star was duly amazed at the way the princess managed to maintain her poise and appearance, even after working so hard late into the night.

Of course, her overtaking him on his patrol meant that now she was in front of him, and he couldn't help but stare. It was completely innocent at first. What caught his gaze was her tail, that shimmering, light-like swath that streamed from her in all its ethereal beauty. Even in the dim castle light, it seemed to glisten and glimmer, almost twinkling with starlight. Iron Star had never laid a hoof on the princess before, but he couldn't help but wonder what it felt like. Would it even feel like a normal pony's tail?

Naturally, his eyes wandered to her backside. After all, her tail was attached to her flanks, and my were they shapely. A common joke among the more bitter guards on the night shift was that Celestia was growing fatter the more ceremonies she attended, because noble ponies were always stuffing their faces with cake while the commoners worked. Iron Star could see a grain of truth to this, noticing just how plump Celestia's rump was. But the other guards could keep their thin pinup mares and fantasize about fit Wonderbolts all they liked. From where Iron Star was standing, a little extra to squeeze was good for a mare. He was looking forward to getting off work more than ever, if only so that he could go home and let his fantasies run wild, thinking about what he might do to that ass if he were ever to have the chance.

"Enjoying the view?"

Iron Star blinked. She was staring at him. Staring at her ass. He was caught. It was all over. He'd be fired. Executed. Publicly castrated. His face must have skipped all the shades of red and was now a starch, fearful white as the blood left it.

Celestia giggled. "I'll take that as a yes."

"P-Prin... I..." Iron Star tried to explain himself.

The princess only met him with her warm smile. "Iron Star, you are not the first stallion to stare at my flanks, and I doubt you'll be the last. It is something that I've come to understand is quite normal for stallions. No need to be ashamed."

At last, he managed to find his voice, although speaking directly with the princess still left him dry-mouthed. "Still, I must apologize for my rudeness, Your Highness. To... ogle... a princess is a dire breach of honor."

Celestia cocked her head at him, raising an eyebrow. "Then how would you classify getting an erection in front of a princess?"

Iron Star's voice left him again as he peeked downward as quickly as possible. But there it was, his pride and joy, standing quite at attention before Her Highness, eager and ready to perform its duties to the princess. He gasped and spluttered, but no words came.

Celestia didn't wait for an explanation. "I'm not sure I understand, though. You didn't see my marehood, did you? That might be problematic."

"No, Your Highness! I wasn't staring at any of that! I was only admiring your tail! Honest!" he answered quickly.

"Honest?" she challenged him, leaning closer. He nodded vigorously. "Then the only explanation for your erection is that you have some sort of... unique interest in my tail." Iron Star shook his head, trying to maintain some level of professionalism. "Hm. Then you must be a stallion who enjoys being pressured and bossed around by mares. Is that it?"

"No, Your Highness" he sputtered, the suggestion totally ridiculous to him.

"Well, then we have a mystery," Celestia said. Her smile turned into a mischievous grin.

Iron Star didn't know what she meant by that, yet he continued speaking anyway, his voice a bit calmer now. "Princess, again, allow me to offer my humblest apologies-" He was cut off by the feeling of warm silk against his neck. The princess had angled herself next to him, using her luscious tail to gently stroke underneath his chin. At this close up, he couldn't see or feel the individual hairs, yet they were still warm and soft like an aurora and his mother's warm embrace combined. That tail made him feel totally relaxed and comfortable, completely at ease as his legs wobbled, his eyes lost focus, and he moaned as it wound around him.

"The clues are starting to come together," Celestia teased. Iron Star's control over himself was slipping. The way her tail rubbed against his cheek prompted him to nuzzle it back, burying his face in the swath of warmth. With a deep inhale, he took her scent in as well. She smelled like honey, sweet and pure.

"No need to confess," she said as she took in every detail of his pleasured face. "I think you've said plenty already." Iron Star barely heard her, only registering the warm notes of her voice as sounds of consent, even encouragement. He dragged his nose across every silken wave, every soft stripe, letting the colors dance before him, wanting nothing more than to be totally enveloped in this banner of comfort, this aurora of soothing warmth. Every bit of tense muscle it touched melted, and every inch of hard skin it touched relaxed, Celestia's expert ministrations better than any massage a tired, bitter stallion could pay for.

His breath came slow but heavy as the stripes of pastel light teased down his chest, winding against his breastplate, coiling through his arms, gently caressing the muscles he had built up over the years of service. Every touch was like a compliment, and Celestia's warm gaze above his was the most enticing compliment of all. Even if he was close enough to reach out and squeeze that plush butt in just the way he had fantasized about earlier, all he could do was try to stay standing under the buttery, gentle ministrations of the princess's tail.

"You're enjoying this quite a bit, aren't you?" she said, not expecting an answer. She chuckled to herself once more, turning her back to him to give her tail better access to his body. But with her butt in his face, he felt a nudge bringing him out of his relaxed state, the sight heightening his arousal and self-consciousness. "Go ahead," Celestia said like a parent at market. "You're a stallion. I imagine you could hardly stop yourself anyway."

With her invitation given, he let his eyes lay on that royal tush. Her flowing tail did cover most of her more erotic bits, but now the scent of honey was mixed with something tangier, something more primal. Was the princess aroused as well? Or was the smell of her skin itself simply that erotic? Iron Star didn't care. He was enveloped in warmth and light, now the rays of her plump butt beaming down on his face, free for him to enjoy.

And enjoy he did. His gaze poured over every soft curve of her ass, the way her cutie mark sprawled over her round backside. Even without contact, he could imagine how giving the flesh would be, the sensation of pressing his hooves against her butt like kneading warm dough. What he wouldn't give to squeeze those cheeks, to pull them apart and reveal the treasure concealed by her tail, to spank her rear and watch her plump flanks jiggle. He could almost imagine how heavenly it would feel to mount that soft ass, to take his stiff cock and bury it into her warmth, to hump her rump wildly while her tail caressed him, inviting him to breed her-

"Ohhh," a long groan left him as the blood rushed to his face. He could feel that velvety tendril of her tail stroking his underbelly, wrapping itself lovingly around his throbbing stallionhood. Slowly, it snaked down his shaft, the warmth and softness of her tail like no mare he'd ever had the pleasure of mounting before, and even the way the tip wound down to caress his full, needy balls was more worshipful and understanding than any kiss he had ever received to his foalmakers.

"Princess," was all he managed.

Celestia's tail gave a quick tug, the coil of her tail stroking of his cock while the tip seemed to give a gentle squeeze to his gems, the flesh sliding forward while the silky warmth of her tail caused pleasure to melt through every part of his body.

His orgasm came without warning, and once it had started, he was at it's mercy. It was all he could do to stay standing as his body was wracked with pleasure, his needy balls all too eager to unload the contents of his pent-up sack, his cock firing pulse after pulse of his seed onto the palace tile below. He did his best to subdue his moans, but when his eyes met Celestia's, her gentle gaze taking in every moment of his powerful orgasm with affection and sympathy, he didn't fight it any longer. Iron Star moaned loudly in pleasure, hips bucked and writhed, thrusting into Celestia's tail as the soft appendage milked him of every drop of pleasure and seed his body could muster.

When it was all over, Iron Star left panting, his length drooping, his hooves still shaking as his semen pooled below him, Celestia chuckled again, clearly pleased with herself. "I knew it," she said.

"Princess... I am so sorry," Iron Star began, not knowing what else to say at his sudden, bold orgasm.

"No need to apologize," Celestia said. She withdrew her tail and took a few steps from him, back on the way to her bedchamber. Before she was too far, though, she turned her head again, her gaze much more in line with the powerful princess Iron Star imagined her to be. "But know that this is far from over. I expect you to attend dinner with me tomorrow night, so I hope you have something nice to wear. We'll see if you have what it takes to be my personal bodyguard."

"P-Princess!" Iron Star tried to speak in shock. A promotion? After that?

"That is an order, Iron Star," she said harshly. After a pause, her eyes flitting about his person, she added. "Also, clean that up before my sister notices. That would be embarrassing."

"Y-Yes, Your Highness," he said, snapping a salute instinctively.

"Good." Celestia turned to leave, but stopped to look at him one last time. "One more thing."

"Yes, Your Highness?"

"When you're done with that, take a break. It appears you are in need of a little more satisfaction."

Iron Star looked down again, realizing with horror that his cock had not retreated back to its sheath, but in the presence of the princess, continued to stand at attention.

"Princess...?" Iron Star started.

Her tone turned more commanding than ever. "Masturbate, Iron Star. That, too, is an order."

With that, Princess Celestia retired to sleep for the evening, her final command causing Iron Star to throb, quite certain that her orders would not be difficult to fulfill.
