When you first arrived in Equestria, you felt like someone had taken you by the legs, and thrown you into the sky... hard. The sensation was very unpleasant, but the resulting journey left your legs feeling like someone had taken one too many stabs up and down its entire length with a red-hot poking iron. Of course, that coupled with you being thrown into the walls of the Canterlot throne room left you seeing way too many stars, even compared to staring at Luna's mane.

Naturally, your sudden arrival, particularly during the presence of the majority of the Day Court petitioners, had sent everypony into a panic. Celestia ordered the guards to haul you away while she and Luna attempted to quell the worries of the panicking ponies. Your blood on the ground, pooling from your grievous impact with the stone wall, did little to help assuage their fear. The guards had to take care in bringing your unconscious body out of the room, lest you woke up and caused more problems for them.

When you came to, you found yourself heavily bandaged up in Canterlot castle's infirmary. Considering the beating that you took just arriving in Equestria, the medical staff and the guards both concluded that you weren't a threat... especially since one of your arms was broken, now sitting in a cast. Nonetheless, the captain of the Royal Guard, Shining Armor, had seen fit to assign a sentry to you to keep watch, and it was her face you saw first, when you woke up.

The bed was a bit small for your tastes, but it was really comfy—you weren't sure if that was the pain or the soft bedding speaking, but you paid it no mind. Your stirring attracted the guard's notice, and she came over to you, her eyes ice-cold and her facial expression stoic. She double checked that you weren't too uncomfortable and went back to her post, maintaining "operational silence," as you would later learn it was called in the Guard.

The incident left you bed-ridden for days. Princess Celestia visited you several times, asking how and why you ended up in Equestria, though you were unable to answer either question. The force with which you entered shattered any notions that you were hostile, as well as a majority of your extremity bone structure, so it was decided that you would stay at the castle instead. Shining Armor soon removed the guard detail, leaving you alone in the infirmary. You were told the wing you were in was very rarely used by the unicorn nurse that came to check on you every few hours or so.

Towards the end of your second week without guard supervision, you noticed something different. The windows of the castle were high up on the walls, far out of your reach, but there was a difference in lighting. It would appear that a pegasus had taken interest in you, as he would oftentimes land on the window directly above your bed—due to your casts and injuries, you weren't able to get a good look at the pegasus, but you could definitely tell that the pegasus was watching you.

This made you very uncomfortable. You didn't know if you were... ugly, or something similar to ponies, so when the nurse came in the next day you asked her about it. She didn't particularly think you were an eyesore, though you were a sight different from a pony, even more so than a zebra! Due to your rather unique disarmament situation, the medical staff had become rather neutral about you, and were relieved that you had been able to consume greens.

After another week in medical, you had finally convinced the unicorn doctor to let you on your feet; the only condition was that the cast stay on for another week, since they couldn't take any chances. The arm felt whole, but you decided to avoid taking chances, too. You weren't a doctor, and although the unicorn was one, he didn't know any better about human physiology than you did, so the choice was unanimous.

The pegasus was back now, but didn't resume observation at the window. Rather, the pegasus had visited you directly: she was a mare, and she seemed to be quite enthralled with you, although you had no recollection of ever meeting her... ever. She laughed when you mentioned it, before explaining everything to you.

"My name is Aqua Lance. I was the guard assigned to supervise you when you were first brought here, remember?"

You nodded in realization as she continued. "I have to admit, when you first showed up the guards were pretty spooked. Ever since the incident with the royal wedding the Captain has had us doing extra training, but none of us had any idea what to do when you showed up. So now the Captain's making us do even more drills," she said, sighing.

You took a good look at her while her head was drooped. She had ocean-blue fur, and a dark grey mane that flowed down to her shoulders; her yellow eyes were scrutinizing your form up close. "So... is it standard guard practice to cover yourselves in flour before you go on duty?" you asked her.

She let out a few more laughs. "That's just the magic in our armor. It helps keep every guard anonymous, that way others won't be able to identify us when we're off-duty. For us and our families' safety, though the guards are usually kept cooped up here in the castle. We don't get a lot of time outside," she said sadly.

"And I guess your unmoving visage while on duty is part of the act, huh?" You sat up in the bed and let your legs dangle over the edge. It had been a while since your legs had moved, and you definitely felt the weakness in them.

"Heh, yeah. Part of the whole keeping-your-identity-a-secret thing."

You introduce yourself, before continuing on. "Guard life, huh? Does Equestria have a military?"

"Nope. The Royal Guard is the only defense force Equestria has, actually." She ruffled her wings a bit. "It's not really wise to attack the alicorns that control the sun and moon, anyways."

While you listened to Aqua go on about the workings of the Royal Sisters, you managed to pull on your clothes. The cast made it difficult to pull on your shirt, but everything else had been fine. The clothes had been cleaned since your arrival, and Aqua tilted her head quizzically when she saw you putting them on. "Why are you wearing clothes?"

A short lecture later, Aqua was versed as to why humans wore clothes. You only gave her the general details, but enough reasons as to why it was important to keep them on.

"Oh. That sounds really inconvenient."

"We have to make do, since we don't have fur and all that," you said.

A bell rang out throughout the castle. "Oh, dear. I'm sorry to leave you so soon. You're really fun to talk to. Usually it's just me and the other mares."

"What are you leaving for?" You got up and start following her.

"Would you like to see?" She smiled at you.

The barracks were abuzz with noise as the guards changed shifts. Although the armor looked ceremonial, the effects of its magic were obvious: variously colored pegasi and unicorns donned their armor, their fur turning snow white or cloud grey, respectively. There was a distinct lack of earth ponies, but they were better suited for other fields of work; Celestia had explained to you how the various types of ponies channeled their magic, and the few earth ponies serving in the guard were there as heavy hitters. Really heavy hitters, she clarified.

Around two dozen or so of the guards shuffled out, while an equally sized group of guards trudged in, their armors clanking loudly against the stone flooring outside the barracks. The morning guard shift had just ended, and it was around time for lunch. The few guards on break took their leave and exited for the mess hall, while you and Aqua followed in behind the morning shift.

"Uh..." You tapped Aqua on the shoulder.

"Something wrong?"

"Are all the guards... mares?"

"Most of them. Princess Celestia's always had it that way, ever since she started ruling. There's a few stallions in the ranks, but I don't think you'll be seeing them. They usually elect to go out and supervise one of the cities instead. I don't blame them; being stuck here in the castle is really boring."

You took a cautious glance around the barracks. For the most part, every guard shared a communal sleeping area, with wooden bunks lining up either side of the room. There was only a room in the back that was sealed off from the rest of the barracks, presumably the commanding officer's quarters. The other side was a bathroom. Unsurprisingly, this reminded you of the army barracks you saw in Full Metal Jacket, except everything was stone and wood instead of... whatever the U.S. Army made their buildings out of.

"And where do you think you're going?" Aqua showed up behind you, as you stood outside the bathroom door.

Quickly realizing your mistake, you backed away in a huff before giving a sheepish chuckle. Aqua laughed as a few of the mares that just went off-duty approached the two of you.

"Hey, Aqua! I see you brought Celestia's guest here."

"Yeah. He's still healing up," she said, looking at you. "I gotta say, you took quite a hit when you showed up. A lot of the guards thought you were dead, at first." The group of mares shared a few giggles among themselves.

"I don't think that's really a laughing matter. I almost did get killed," you said, waving your free hand at the cast that encompassed your left arm.

Just as Aqua was about to retort, there was a loud series of clanks that hit the floor. Everypony in the barracks turned toward the source of the noise, where two mares were cleaning up their armor that had fallen on the floor. The storage rack they used looked fairly dilapidated.

"Wow. That looks..." you began.

"Broken? Yeah..." Aqua said. The other mares had gone over to help, while Aqua stayed to talk to you. "Ever since the attack at the Royal Wedding, things have been going downhill. Captain Shining Armor has been run ragged trying to keep everything together, and, well..." She looked over at the officer's quarters. "We used to have a barracks caretaker, here, but she turned out to be... a Changeling."

You nodded solemnly. Princess Luna had told you about the thwarted invasion during the Royal Wedding—mind control, shape-shifting... the whole shebang. A security nightmare, for certain. The attack had happened about a month before you arrived, and with your medical stay it was now two months later, more than enough time for things to begin falling apart.

"It's a fairly hard task. No pony has offered so far, and with us guards on duty and training..." There was another loud clang. "It's a wonder how the whole place hasn't fallen apart yet. The Captain's been looking for a replacement, but—"

"I'll do it," you blurted out.

Aqua turned to you, tilting her head as if she didn't hear you correctly. "Huh?"

"I'll do it," you repeated. You didn't take yourself to be that much of an organizer, but now was as good a place as any to start. They needed the help, and you had to pay off your debt to Celestia's hospitality, as well as the other ponies here. She would probably wave it off, but you knew better. You're a hard-working human, after all.

Aqua looked at your arm. "Are you sure? I mean, that cast..."

"The doc said it should be off by the end of the week. I'll begin work in earnest, then."

"Well, if you say so. Let's go find the Captain."

Shining Armor was actually relieved to find that you wanted to volunteer. Apparently, it had been a whole different kind of hell trying to search for somepony who actually wanted the job; no one wanted to do it! Celestia had several candidates in mind, but Shining was just happy that you volunteered, and since you were a human, the background checks were fairly swift. Changelings could only disguise themselves as four-legged beings, which made sense since the dragons and griffons also walked with four legs. Humans weren't on the list, especially since you were the only known human in the world.

After a brief spell to make sure no odd magics were on you, you were formally instated as the Royal Guard's new barracks caretaker. The officer's quarters in the back were yours, and they came with their own private bathroom. A convenient feature, given the gender of the ponies you were bunking with.

Being the barracks caretaker meant that you had to take stock of everything there: from the bunks to the equipment, even the bathroom, though Aqua covered for you when you were inside inspecting it. There were plenty of things that needed fixing in there, and you used your one free arm to note everything on the portfolio that was left behind... apparently whatever the Changeling was doing here was intentional; notes about destroying or misplacing equipment on purpose, covering up problem spots—you were certain if a handyman were here, he'd charge at least a thousand dollars to fix it all!

You sighed as you closed the portfolio. And this was just for your quarters and the bathrooms alone, as there was no telling how much damage was caused in the main barracks. At least the Changeling had bothered to keep her quarters (well, your quarters now) in good condition: the bed was far larger than a usual pony bed, for some reason, but you didn't complain. It fit you just perfectly, with room to spare.

Your quarters had a nice open view of the Canterlot courtyard, looking down on it from the second floor. From your vantage point, you could see the Royal Sisters enjoying some afternoon tea, as well as various attendants bustling to and forth from the castle itself to keep the Sisters accommodated.

A knock from the door breaks you out of your sightseeing, as Aqua entered your room.

"Hey there. Got anything done?" she asked.

You shook your head. "It's horrible, Aqua. Just—I've never seen anything so bad in my life! Look." You opened the portfolio to the notes the Changeling had taken, easily over four pages worth of documentation regarding the destruction of Royal Guard property. "All of that. And that's just for the bathroom."

Aqua's expression changed from concern to horror as she looked over the notes. "I—we used those! I can't believe—oh, sweet Celestia. Just... just take it back," she says as she hands you the portfolio, putting a hoof over her mouth. "I think I'm going to be sick."

"I'll talk to Shining Armor about this. As of now, the bathroom is off limits. Please spread the word to the other guards about this. If they want an explanation..."

"I'll try to make it as obscure as possible," she bluntly stated.

***

The next few weeks were spent identifying solutions to the problems in the bathroom. It seemed like most of the things were intentionally broken by the Changeling, but there was also minor secondary damage, probably due to negligence. Shining Armor was appalled to hear about all the damage the Changeling had caused: apparently, she came across as a reliable mare. You told him that it wasn't that big of a deal, and the damage could easily be reversed. However, it was in the best interests for the Guard to fix the bathroom as soon as possible, so now here you were, supervising a few repair ponies.

Even Princess Celestia had seen fit to visit you. She had heard the news from Shining Armor, and was pleasantly surprised that you had volunteered to take over the position of caretaker. With your extensive notes on the state of the barracks, Celestia had brought in extra help to finish up the repairs in record time, bringing everything back up to standards within the month.

During the reconstruction, you had gotten to know the Royal Guards a bit better, since you saw them all the time when they were on duty, and true to the magic, you weren't able to tell them apart. Which, of course, earned you the laughter of various mares when they visited you during their off-time and had you play the guessing game over who you met with clues and teasing. It was an excellent conversation starter, but the mares always went off on their own tangents; you could tell they'd been starved for somepony to talk to, especially since they were on the castle grounds all the time.

On top of your caretaker duties, you also found work in the cafeteria's kitchen: the variety of things you could whip up, even if it was wholly vegetarian, surprised even the most seasoned chefs on the staff. You didn't have access to a lot of the spices present in the human world, but good old salt and pepper made up for it. Salsa was pretty big among them.

Mostly, though, it was you just tossing together things that sounded like they belonged together, and it worked. You didn't complain, and you made sure to remember how to make the various dishes that the ponies now adored, sharing the recipes with the chefs. It was a slow day today, and the head chefs had shoo'ed you out of the kitchen for lunch break, eager to try their own hooves at the recipes you had made a few days earlier.

You sat at a cafeteria table by yourself, before you see a tray suddenly land next to you. Aqua takes a seat next to you as you finish consuming your cucumbers. She, like most of the castle staff, had taken a liking to your exotic take on Equestrian fare to the point of eschewing the normal menu normally dictated by the nobility, since the chefs also served them, in favor of your creations.

"How's it going, chief?" she asked. "I guess I have to start calling you that now."

You gave her a confused stare as you chewed your food.

She looked at you in surprise. "You don't know? Well, this should explain everything. Here," she said, handing you a wooden case, roughly the size of a shoe box. It seemed fairly mundane, and contained only a simple brass latch on the front of it. Was it a gift?

You put down your fork for a minute and opened the box. Inside rested a pants and shirt combo, trimmed with white, with the seal of the Royal Guard rested squarely on left side of the shirt. The material felt light and breathable, while the pants were made from a durable material that felt rough enough to withstand a scuffle. On top of both of them rested a small pin, a shield with Celestia's sun in the center of it, imposed on top of a pair of pegasi wings. Your eyes widened in realization.

"Welcome to the Guard!" Aqua patted you on the back, as a few more of the off-duty mares joined you at the table. You had stopped chewing in surprise, and simply took the pin in your fingers and looked at it. This certainly was interesting... did you just get drafted? The other mares clapped their hooves together as congratulations for you.

"You're the chief officer of the barracks now. The Captain is impressed with how you handled it all, and in such a timely fashion, too. I think even the Princesses are impressed with your work. Of course, your rank doesn't really mean much in the rest of the Guard, but the Captain thought it would be nice to reward you somehow."

You finished the food in your mouth and swallowed. "So does this mean I have to do drills with you all now?" you asked.

The mares exchanged glances and conversed a bit; it seemed that none of them knew the answer. Shining Armor didn't specify whether you were to join the guards on their drills with your new-found rank, and you wondered what kind of drills ponies did: push-ups seemed kind of odd for a pony to do, since they were on all fours all the time... sit-ups wouldn't work, either. You suspected that it consisted mainly of running for endurance building and specialized exercises for the unicorns and pegasi. Where would you even fit in?

"I see you accepted the offer," you heard a familiar voice come from behind you, and turning around, you see the sender: Captain Shining Armor himself. He smiled a grin at you as he trotted up to your table.

The mares gave him a brief salute before they returned to their food and chatting, with the exception of Aqua, who faced Shining Armor alongside you. "Captain, does the chief here have to participate in our training sessions?" she asked.

Shining put a hoof to his chin. "I'm not so sure that would be wise. You aren't capable of flight or magic, so I think you just might get in the way. I do, however, expect you to be wearing the uniform from now on. Have to keep up the professional look, after all. Your rank actually has one more responsibility to it than just barracks caretaking, but Princess Celestia will explain that to you in due time."

You salute the standard military salute. "Yes, sir."

"No need to salute me, 'Chief.' I'm kind of glad you got a nickname. Your human name doesn't exactly roll off a pony tongue, unfortunately."

You didn't mind getting a nickname. Actually, you had wondered why it took you this long to get one, since the mares had expressed on more than one occasion just how strange your name sounded. At least it wasn't something worse, that was for certain. There could have been a variety of nasty nicknames for you, especially since you were a foreigner, an alien, in Equestria.

Shining Armor bid you all a good afternoon and left to return to Princess Cadence, leaving you and the mares to finish your meals, although the expression on their faces showed that something significant had just happened... was it pertaining to what the Captain said? "Er, Aqua? Is something wrong?" you asked.

She immediately looked at you, eyes as wide as a deer's in headlights. "Hmm? Nothing, nothing at all." The other mares nodded their heads in agreement, albeit a bit too eagerly. They were obviously in on it, too.

"Does it have something to do with that additional 'responsibility' Shining Armor was talking about?" you asked, pressing the issue. Aqua's eyes shifted around before she returned to you with an answer.

"It does, actually. But if Princess Celestia is going to explain it to you, who are we to tell?" The mares nodded again, this time in solemn agreement. Further attempts at trying to get an answer were only met with the "you'll see" response. Just what was it with this responsibility that required that it remain top secret?

“Well… I suppose I can let you know a little,” she eventually said, after your repeated prodding. “You’ve been here a while now, and you’ve settled in well enough. Do you find mares attractive?” You nearly choked on your drink, but you figured that if it was important to this little secret, you might as well answer. That, and being friendly enough with all the mares meant that they would be willing to hear things out if what you said was taken the wrong way.

“If I’m being honest with myself, yes,” you said with a nod. “You’re all easy on the eyes, and you get used to it eventually.” A few of the mares had caught you staring at their flanks on more than one occasion, and you knew they were prone to gossip. Being stuck here only reinforced the sexual frustration that stemmed from the lack of privacy, frustration that had you focusing on the fact that you constantly interacted with the opposite sex. Aqua didn’t know—or perhaps she did—but you didn’t say any more.

“Then trust me when I say that you might not be entirely unreceptive to this responsibility.” Aqua hummed to herself as she collected her tray. “And that’s all I can tell you. Good day, chief.” She continued humming to herself as she left, and you noticed a greater bounce in her step.

You were only notified of your staring at Aqua’s buttocks when another one of the mares cleared her throat. Looking back, you blushed and found it better to focus on the minute details of your fork as you heard the other mares giggle. At this point, you had a fairly good idea of what to expect of this responsibility, but there wasn’t a chance that anything like that would be considered an official duty… right?

You rose up from your bed, enjoying the morning shine of Celestia's sun cutting through the curtains in your room and hoping today would fare well. The day before had not been great: Princess Luna, with some help from Princess Celestia, had finally managed to find a spell to send you home. The problem, though, was that your method of leaving Equestria would be similar in fashion to the way you entered it. That is, at high velocity. On top of that, since Princess Luna had no knowledge of Earth, the spell could theoretically drop you off—or above—anywhere in the world randomly. You remembered that seventy percent of Earth was covered in water, and frankly... the trip was just too risky. So in Equestria you stayed.

And today was your birthday. You barely remembered mentioning it ever since you came to Equestria; the only instance was to Shining Armor, in one of the many chats you had with him on a weekly basis, reporting to him and generally being one of the "guy friends" that he had. The entirety of the guard was made of mares, and Prince Blueblood wasn't much of a conversationalist either, despite Shining Armor's connection to Princess Cadence.

The other instance was to Aqua, though you wondered if she remembered, or if Equestrian culture had any event based around a birthday. You hadn't seen any pony celebrate their birthday once since you arrived, with the exception of the Royal Sisters, although that probably had more to do with the fact that, like the Royal Guard, you were kept within the confines of the castle. Maybe the Royal Sisters' importance meant they were the only ones who celebrated birthdays?

You didn't put too much stock into it. It had only been a few months since you arrived, and you didn't want to push the envelope when it came to customs. Every pony in the castle had been incredibly accepting of you, with the exception of Prince Blueblood—whose pompous demeanor was standard for a stallion like him, Aqua had informed you. The guards were your best friends, with the chefs being a close second: they enjoyed being around you, even if it was to just idly laze around and just talk.

It was during one of these sessions with Aqua that you learned a little more about why most of the mares became guards. There was no conscription: all of them had volunteered for the job. Aqua herself came from a long line of guardsmares, going several generations, as far as Nightmare Moon's banishment, and a bit before that. Most of the other mares had similar stories as well, stating that Celestia was very picky about which ponies ended up in the Royal Guard, and very rarely accepted new lineages. Of course, from what Aqua said, the job is very boring and pays decently well, but there wasn't much else to do, with them being restricted to castle grounds, other than talking and reading books.

And that led to your current daily "lounging" time, as they call it. At first, the lounging had consisted of conversation items like your past, the nature of the being that is you, and where you came from, though you left out the unsavory bits of human culture. They, in turn, regaled you with stories about their youth, their pony types, and the various cities they came from. Cloudsdale was the one that fascinated you the most, since cities made of clouds weren't exactly common on Earth, and you managed to catch sight of the city once or twice from Canterlot's vantage point.

You returned to the barracks from your lunch break; a simple garden salad had satiated your appetite this day, and you found a few magical theory books written by a pony named Twilight Sparkle you wanted to read. Her vocabulary was really hard to understand, but you couldn't help but read the book. Magic was an intriguing and mysterious field of study, after all, and before you arrived in Equestria, you'd simply thought it a myth. So with the books under your arm, you returned to Aqua to engage in another bout of conversation with the usual group.

Today, though, when you entered the barracks, you noticed that the layout had changed. Most of the beds had been moved aside to create a large clearing in the center of the barracks, where a large fluffy mattress had been laid out. It was easily the size of five beds, probably more, and the mares were laying about it, chatting or reading books. You met eyes with Aqua, and she smiled at you.

As the door clacked, closing behind you, Aqua motioned for two of the mares to get up. They ran over to the door and... bolted it locked? Okay, something weird was going on today. The other mares cleared off the giant mattress while Aqua approached you, a strange movement in her gait as she trotted to you.

"Hey there, chief. We've been waiting for you." She motions for you to sit on the mattress, and you complied.

"Is there something wrong, Aqua?" you asked, feeling your face growing ever warmer as you noticed their swaying walks. The other mares were now gathered in a circle around the mattress, making you feel very uncomfortable as you realized the smiles on their faces were a bit too enthusiastic...

"Has Princess Celestia told you about your other responsibility yet?" She trailed a hoof around your chest in a circle, looking at you with expectant eyes. Oh, gosh, was she trying to court you? You always knew that Equestria was a matriarchal society... they couldn't possibly be...?

"No?" she continued. "Well, I guess we'll have to tell you ourselves..."

Your busy mind's questions were answered as Aqua pushed her lips onto yours, eyes closed. Her forehooves pushed you down onto the mattress, her tongue cautiously making its way into your mouth. She was making out with you, right here in front of the other guards!

"So it looks like Her Majesty hasn't," Aqua said pulling away from your mouth, a line of drool connecting her mouth to yours. "Oh, well... consider this your birthday present," she said, smirking at you. "A great big thank-you from all of us here." A few of the unicorn mares had taken the liberty of gently stripping you of your clothes in a swift few seconds, and now you laid on the bed as naked as the day you were born, except for the fact that your certain special part had been rising, in no small part due to Aqua's initiative.

“Whoa, whoa, hold on a moment. This is what you were talking about?” you asked, covering your manhood with a pillow grabbed from the piles around you. True, it was flattering to be surrounded by mares—mares you’ve taken a liking to recently—who were willing to get it on with you, but you imagined that the surprise would be less… numerous. Perhaps just Aqua, or a handful, but to have the whole unit?

“Yes. Is this… not okay?”

You laughed, but the shock left you wide-eyed, an expression that caused a stir among the mares as you looked between them. “I mean—I am just at a complete loss of words for this.” You buried your face in your hands as you shouted into your palms. Only when you felt like you had shouted out all of your surprise did you look to Aqua. “This is my responsibility—and birthday present? I have to do all of you?”

Aqua blinked. “Yes.”

“Well… I can’t say I didn’t see this coming,” you said. So much for being a joke, now you got to have the pick of the whole unit. Truly the greatest responsibility placed before you if you’d ever seen one. You removed the pillow and sat back. “Give me your best shot, Aqua.”

"My, eager to get started, are we? Well, a good mare shouldn't keep her stallion waiting." Aqua batted her eyelids as she moved to straddle you. A few of the other mares followed suit, sitting down on the mattress and curiously examining your manhood.

Your attention is drawn back to Aqua as you felt a warm sensation surrounding said manhood. Aqua had both of her forehooves placed on your chest, eyes closed and panting heavily as you slid inside her. Looking down at where you two joined, you see that Aqua's folds have swallowed you all the way to the base, and you could feel resistance meeting your tip as you felt your body tingle.

"How is it, Aqua?" one of the unicorns chimed up.

"So... oh, Celestia, it feels so great bareback..." Her tongue lolled out of her mouth as she finished the sentence.

"I'm sure you're wanting a bit of explanation, right?" One of the unicorn mares was now eye-to-eye with you, although her face was upside-down from your viewpoint. You felt Aqua start moving again, sending shivers of pleasure down your spine. "Every mare has something called an estrus cycle. To put it bluntly, we have periods of heat where our body forces us to copulate," she said while waving a hoof at Aqua.

Of course, Aqua was now picking up the pace and the pleasure you were feeling was making it hard to listen to the unicorn, but you soldiered on anyways, not wanting to disappoint Aqua as the unicorn continued. "Since you're not a pony, it makes it very convenient for us, you see. We can enjoy ourselves since we don't have to worry about getting pregnant. You're a very nice stallion, and we've all discussed this beforehand... we hope that you'll help us satisfy our urges," she said, before planting a kiss on your forehead.

You grinned sheepishly at the gesture. "I'm sure I can... accommodate... all of you girls..." you managed. You were fairly acquainted with all the mares in the barracks now, and pony appeal had began rubbing off on you since long before this moment; teasing looks, toned flanks and swishy tails were about one of the most flamboyant ways to arouse, you learned, and you realized now why they'd toned it up in the past few days. In any case, you certainly didn't mind obliging their request.

Her returned mischievous smile accompanied her growingly sultry voice. "I'm glad to hear that, chief, but I'm sure your attention should be on a different mare..."

She moved out of the way so you and Aqua could finish together. Aqua smiled that naughty smile of hers as she looked down at you, eyes half-lidded, before she drew closer and laid down on your chest, her head on your left shoulder. She exhaled cute moans and heavy breaths right next to your ears, making you that much more horny and driving you crazy. Her wings expanded into the air as her passion rose, and you trailed your hands down along them, eliciting a shudder from her as you continued your rhythms.

You drifted your hands southward, grabbing her buttocks and guiding her with them, thrusting harder and eliciting a loud moan from her. From your vantage point, you could see a few of the other mares stare in awe as you continued to grind into Aqua, some of them with hooves over their mouths. These hands of yours were the coup de grâce, capable of doing many things that ponies could only imagine of doing... among others. You intensified your exploration, touching her, feeling every part of her body, with her sudden rises in volume letting you know that you were hitting all of her sweet spots.

The light of the afternoon bled through the windows and reflected off of Aqua's blue coat, slick with sweat. You could feel her forehooves reach around your neck, bringing you closer into her embrace as she kissed you deeply again. Her lips were brought away as she was caught short; you gently brushed your hands down her spine, slowly dragging it right across the point where her wings connected with her body. You felt her entire body tense before she quickly rebounded and dove straight in for another kiss. Her tongue roamed your mouth as you could feel her hold on your lower half clench up in response to the sensual stimulation, and you caught the taste of sweet mint on her saliva—had she been preparing for this?

You took your right hand—the left busy tending to her hindquarters—and ran it through her mane, steadily increasing the rate at which you were pumping into her until you could feel her inner warmth bear down on you in full force. Your grunting breaths reached a breaking point as your attempt to warn her of your impending orgasm simply exited your mouth as a series of low, incoherent babbles cut off by your restrained moan. You saw stars as you released yourself within Aqua, and the scream she let out as she collapsed on your chest was proof of your effort to please her.

Aqua fumbled as she stood up, her legs shaking, and instead decided to slowly roll off, moving herself off of you. You could see the slick of your seed covering the majority of her crotch, and she fell over on her side with a satisfied sigh, before looking at you with a faint smile on her face.

"That's quite a thing you got there, chief," she panted. "But it's not over yet..."

As she said this, three of the unicorn mares approached you and enveloped you with a field of multi-colored magic. You could feel strength pour into you and your stamina slowly recuperating... and your sexual drive amplified ten-fold, as your member quickly made itself erect again, and the sight of luscious flanks quickly overwhelmed your mind.

The unicorn mare who explained everything to you earlier, who you now recognize as Scarlet Spark, approached you and laid you back down on the mattress much like Aqua did, but with a gentle hoof. The other two unicorn mares, Red Rhapsody and Sunbreeze, took positions over your head and behind Scarlet, respectively. The trio were a perfect mix of various shades of red, and it almost looked like you were making love to the sunset itself.

They said nothing as they assumed their positions, and you understood what they wanted. You began licking Rhapsody's marehood, which prompted an innocent gasp from her—she was fairly young compared to the rest of the guards, and this would be her first time doing this. Sunbreeze and Scarlet were among the older guards, generally acting as the 'sister' type to ease new guards into their lives... and into the solutions on how to cope with estrus.

Just like they were doing now. You felt a tingling sensation on your chest, which you assumed was Sunbreeze giving your bare chest a lick, before you felt a pair of hooves guide your hand to a mare's vagina and noticing her husky voice moan—yep, that's definitely Sunbreeze. You began fingering her while using your free hand to spread Rhapsody's lower lips and moved deeper into her with your tongue, weaving it in, out, and all around as you pushed her rear closer to your face.

Scarlet was the oldest of the three, and obviously showed some confidence with the smile she had on her face as she lowered herself onto your spear. You could feel resistance, just like you did with Aqua, as you penetrated deeper into her, but the sharp gasp she let out betrayed that confidence—without a doubt, none of these mares had been with a stallion—so you hopefully assumed—before, and that both humbled and honored you to both take their virginity, as well as satisfying their urges. You're the luckiest stallion in Equestria!

The three gave out their own unique moans as you pushed deeper into them. Rhapsody tasted slightly tart, and her scent was overwhelmingly that of flowers. Her cute red butt eclipsed your view of the other two, but you wouldn't have it any other way, content in the fact that you were pleasing all three at once. You could see out of the corner of your eye the red-orange hooves of Sunbreeze stroke her clitoris as your fingers drilled into her; you had started with two, and now you were on three, and increasing the pace to match her steadily rising frequency of held-back moans.

Scarlet had fallen into a rhythm of alternating between fast and slow movement: short strokes while moving quickly, then raising herself to the point where your penis would exit her, slowly... but never pulling out. The feeling was incredible, and served very well to keep you on the breaking point, but always just short of the point to push you over. The carmine mare was very learned in the hows of sexual technique, that was for certain; unicorns tended to be a bit more knowledgeable than their winged and strength-bearing counterparts.

You were slightly worried about the fact that there were earth ponies that would undoubtedly be in estrus, as well. They'd have a phenomenal amount of endurance, and that coupled with their guard training made you wince to think about satisfying them. They were still out on guard duty at the moment, which was a temporary blessing to you. Still though, pleasuring a group of some of the most accomplished fighters, fliers and casters of Equestria was something that made your mind go kaput.

Sunbreeze had completely collapsed onto your arm now, savoring the sensation of your fingers digging into her. You could sense a dull glow come from her horn, an orange hue slightly brighter than her coat color surrounding her appendage. Scarlet and Rhapsody also had similar glows around their horns, and you took that as a cue to move faster to bring them all to the point of climax.

A bunch of faint hissing and popping could be heard as you brought the mares to orgasm, before a loud pop rang out and the room was illuminated with various hues of red and orange, if only for a few seconds. Rhapsody came so hard that your face was covered in her juices, before she fell over to your side. Noticing your soaked face, she quickly moved toward you and began cleaning your face with her tongue, giggling as she did so.

All the while, you could feel an abnormal amount of seed pump into Scarlet. No doubt something to do with the spell they cast on you, you thought. The contractions of her wall forced every last drop out of you, and you were rather surprised that she didn't scream, but then again, Scarlet was never really the loud type. She bit her lower lip out of pleasure, before slowly sliding off of your rod, a trail of white liquid dripping out of her vagina. Sunbreeze merely continued laying on your arm, eyes closed as she collected her breath.

"You certainly know how to please a mare..." Rhapsody said, smiling at you.

"Those hands of yours are really awesome!" Sunbreeze said, pecking you on the cheek.

"And you certainly aren't lacking down here," Scarlet said, as she prodded your penis with a hoof. It was still rock hard, even after filling her up. You finally realize that the other mares had moved closer, almost uncomfortably so as they gazed at your hands and your penis with desire. The three you had just satisfied moved off, and a few more moved to take their place as the unicorns made sure the stamina spell casted on you was still in effect.

It was going to be a long day...

And a long day it was; you had finally managed to get into your room and slump onto your bed. These athletic mares could get downright horny at a moment's notice for multiple rounds, and although you had satisfied Aqua and the rest of the night guard, there was still the matter of the day guard... which consisted of just as many mares as the night guard and the dreaded earth ponies. They had to blast you with that stamina spell six times to keep you going through all of them, but now it was done, and the mares had returned to normal. You, however, felt like you had been run through a wringer, and definitely needed the rest. A few days sounded good to you. No one would notice that you were gone.

A knock on the door startled you, but the rest of your body was too sore to move. "Door's unlocked," you hoarsely shouted, and Aqua entered your office, closing the door behind her.

"Hey there, chief. Sorry you had to go through all that... we promise that we'll go easier on you next time."

You barely nodded, your neck muscles screaming with soreness. But you wanted to at least be presentable to her, so you struggled to sit up, and began rubbing your sore muscles as you continued to listen to her.

"Usually when our heat periods come around, we have to weather through it without any help from anypony else," she explained. "There is medication for it, but... it's kind of expensive, so a lot of us trained ourselves to resist the urge while we're on duty and relieving it when we're not. But when you showed up, and then volunteered for caretaking duties... Princess Celestia saw an opportunity. I hope you don't hold a grudge against her... or us."

"It's not a problem, Aqua," you reassured her. And it wasn't. Only in your dreams would a group of females propose the idea of an orgy to you, but here you got a whole week's worth of it condensed into a single day. If anything, you wanted to thank her for allowing you to share in such an awesome experience, which you do. "I... have to thank you for letting me do this... one thing I can cross off my bucket list... and you're all beautiful mares..." you ended, wiggling your eyebrows at her.

She blushed. "I'm... glad you're taking it well. Usually if a stallion has to deal with this, they... well, let's just say they try to run away, or hide. The Captain was never really one to help us out with our urges, and I can understand that. He's really by-the-book, and he didn't really want to take advantage of us, especially since he's married now. But you," she said, trailing closer to you and placing a gentle hoof on your knee. "You took this duty to heart, just like everything else you've done. For the Guard. For me."

All of a sudden, she brings her face close to yours and locked your lips into a kiss. This wasn't the same kiss that you shared before; it was sweet, gentle, and loving. You brought your arms around her and held her closer as she did the same with her forehooves, extending the kiss for just several more seconds before breaking away.

"And besides," she said with a glint in her eyes. "Everypony around here knows that you belong to me."

"I belong to you now, do I?" you amusedly asked. You rubbed the back of her neck and feel her tense up, then relax as she recognized your massaging.

"And I belong to you, right?" Her voice carries a hint of worry.

You again ran your hand through her mane and kiss her on the muzzle. "This has been the strangest way anyone has ever asked me out," you said, laughing at her flustered expression.

She shared your enthusiasm, laughing with you before nuzzling you on the neck. "I've had my eye on you for a while, you know. A lot of the other mares are kind of jealous of me for being so close to you," she admitted. "But you're the spitting image of a stallion every mare wants. You're kind, and generous... by Celestia, you even volunteered for Blueblood's catering! Nopony wants to do that, even with the pay, but you did it anyways out of goodwill! I swear, you're too nice for your own good."

You simply chuckled and nodded. That catering service... though the food was great, the event was a disaster—another one of Blueblood's ill-fated attempts at impressing the aristocracy. A unicorn chap by the name of Fancy Pants sent his regards to you, though - apparently Blueblood usually ended up ordering catering from out-of-town, and the food wouldn't have been fresh. Fancy Pants and his companion, Fleur de Lis, certainly enjoyed your unique take on the typical daffodil sandwich, at least.

"Anyways, the heat's over for now. I think I speak for everypony in the Guard when I say that... you're really good in bed," she said, giving you a wink. "A few of the mares are still having after-heat problems, so you should probably expect a few to ask you for some help... others might just approach you looking for a quick fix," she contnued nonchalantly. "I know Rhapsody has her eyes on you, and Sunbreeze keeps glancing at your hands whenever you're around. Not sure about Scarlet, though... she's really hard to read. But, yeah, just telling you to expect something soon!"

You sighed, groaning as you massaged an arm, the soreness reminding you of your need of some time off. "Do I really have to...?"

"Oh... totally forgot about that, haha. Well, I'll tell the rest of the mares to keep away for a while. You look like you're in some serious pain," she said, rubbing a hoof on your arm. "Get well soon, okay, chief?" She smiled appreciatively at you before leaving your room, the last of her that you see being her beautiful eyes. A faint 'clack' followed as she closed the door and left you alone in your quarters. You made a lazy attempt at removing your uniform and toss it onto the bedside chair before you covered yourself and drifted off to sleep.

You dreamt of a very pretty pegasus that night.
