A Swift Guard Change

Guarding the Canterlot Palace could be tiring work, even if all one did the entire day was stand around or patrol the halls. After all, the gilded armour wasn’t light, and the crushing boredom was tiresome by itself.

The sleepy passage Swift Wing found herself in was quite significant, being a side passage for the cooks and maids to make their way to either of the Princess’ quarters, with the setting sun leaving the corridor hot and stuffy. It was rarely travelled outside of specific times, and much of her day was uneventful, leaving her to stew in her thoughts, distracted by ideas that floated through her skull.

Those ideas were quite lewd, given she was in the middle of her estrus cycle. The tall blonde, clad in golden armour that showed off her abs and strong arms and legs, had done reasonably well for the past few days, dealing with the heat throughout her body, the fog in her mind, and the tingling between her thighs. That was mostly because her commanding officer was understanding enough when she mentioned her troubles to let her swap out early and to keep her somewhere she didn’t have to answer the questions of tour, dignitaries, or nobles.

But, eventually, all good deals come to an end, and not only was Swift at the end of a long shift, but her afternoon relief was sick. She’d stood there for a total of five hours longer than she expected to. The effects of thirst and hunger were enough for her to deal with on a good day, but with how much Swift ached and the sweat that soaked her underskirt, it was safe to say she was very worked up.

She’d been counting down the minutes since she received the news she was to wait longer, trying to keep track of the time. That part of the palace had no clocks, and the lack of regular staff passing through meant she couldn’t even count the hours by the delivery of meals or missives.

The afternoon stretched out, the room getting hotter, and Swift’s mind turned toward her coming relief. She wasn’t to be relieved by another Day Guard but instead by one of the Night Guards. Who she was to expect, she didn’t know, but the newly reinstated force had piqued her attention over the past year. Initially, she thought it was silly, but they’d proven their worth in their prowess and attentiveness, among other things.

An ear twitched, and she flicked her eyes down the corridor in the vague direction of the Lunar barracks to the west. Hoofsteps faintly echoed through the hall, then became muffled by the carpet laid down for the staff and the Princesses, should the latter make a rare passage through those halls.

“Stop playing with it. You’re not doing yourself any favours.” Swift assumed the voice belonged to a stallion, though she could have been wrong. It had a slight accent, shared amongst the Night Guard, and a cheerful tone to it.

The hoofsteps were getting closer, about to round the corner.

“I gotta get it under somehow.” While deep, the other voice sounded like it belonged to a mare. “I’m standing opposite Celestia’s chamber, and she’ll be passing by me…”

The pair rounded the corner, short spears in hand. Her assumptions were correct, with a stallion and a mare walking up toward her. They had deep, dark blue coats like the night sky, the mare’s speckled with little white freckles over her shoulders and chest, and where her armoured skirt flicked up as she walked, on her thighs too. Each had black, leathery wings folded behind them and similar bluish-purple manes, the stallions a loose mop and the mare’s braided behind her back.

Given they carried their helmets under their arms, Swift reckoned they were running a little late, but she didn’t care. She was going to be good and gone to relieve herself in other ways momentarily.

Thestrals. Luna’s own. A newcomer to the Guard as of recent years, but Swift liked them enough despite some lingering prejudices in the Day Guard. The fact there were two of them was all the confirmation Swift needed to know that her shift was over, and she sighed.

She did catch that the mare was walking bowlegged, with a hand pushing her silver armoured skirt down where it wanted to bump up. A familiar scent filled Swift Wing’s nose, making her eyes unfocus, so she stared directly ahead for the last few moments she had until she was free.

The stallion whistled at his companion. “Wow, okay. That kind of sounds like you’re in rut.” He chuckled and patted his companion on the back. “And with the Princess so close? I’ve got a feeling you’ll be dripping by morning.”

The mare growled, prompting another laugh from the stallion. Both stopped in front of Swift Wing, the smell now at its strongest, an unmistakable musk of a stallion—or mare, in this instance—in rut.

She caught the mare’s flared nostrils, and the two looked at each other, their eyes dilated. The mare stood half a head shorter but was as strongly built as Swift. She had a similar figure, too, with wide hips and a large bustline that likely led to similar adjustments to their breastplates. Swift’s eyes flicked up and down the thestral, onto her toned, exposed stomach, then her solid arms and legs. On a good day, they would be a close match in a fight.

Right then, though, Swift was sure the mare in front of her could fold her in half.

“Corporal Night Owl, your relief.” Like most Night and Day Guards, the saluting stallion was similarly dressed. The armour of every one of the Royal Guard left some protection to be desired, but they were an elite force in a ceremonial position. It was also possible both Princesses enjoyed a little eye candy. Swift couldn’t begrudge them that, and she enjoyed it too.

She refrained from licking her lips as her eyes wandered to their toned abdomens. She really enjoyed it some days.

“Uh, Corporal Swift Wing,” she replied after a moment’s pause. “This station is now yours.”

The stallion nodded, and the two dosie-doed around each other. It was a ceremonial handshake, no hands touched, just a swap of who stood where in the middle of the hall. Once in his place, Night Owl slipped on his silver helmet, sporting the black-haired like-frill that helped give the Night Guard their reputation.

His nostrils flared, and a grin spread across his face as he glanced between the two mares.

“Neb, this is your first time in these particular halls, correct?”

‘Neb’ nodded, and the stallion’s smile broadened.

“Wing, these your usual stations?”

While Swift Wing shook her head, she did add, “Only this spot, but I pass by.”

“Go show Corporal Nebula where to stand. Luna’s retinue will have left with her already, I think.”

Nebula and Swift shared a glance, breathes both hitching in their throats as they realised what Night Owl just did to them. Swift’s reaction immediately after that was to blush while Nebula beamed.

“Thank you, Owlie,” Nebula said.

“Thank Corporal Wing. She’s the one helping you.”

The distinct feeling of being caught in a trap she hadn’t a hope of detecting sprung to Swift Wing’s mind. Nebula gestured forward with a hand, and Swift took the lead.

The corridors in the palace could be a little winding at times. A lack of signage and various dead ends served as one more line of defence. It also meant that anypony unfamiliar with one part of the palace’s layout could quite easily get lost. Most junior royal guards, Day and Night, had gone through a hazing ritual where they were given the wrong directions and stumbled upon the personal Royal dining chambers when Celestia was eating or something worse.

Swift shook her head, pushing the memories out. What Celestia did in her own time was hers alone to know. She knew the way to the two Princess’ chambers quite well, occasionally being assigned as the ‘opposite’, the Day Guard standing opposite Luna’s chambers.

She spared a glance behind at Nebula, smiling meekly at her, though her eyes were invariably dragged downward toward Swift’s groin.

The thestral made no attempt to hide her pride now that she had a target, and Swift gulped. The wetness between her legs spread a little when she spotted the dark, onyx flare bobbing beneath Nebula’s armoured skirt, pushing it forward more with every step.

Swift stumbled down the wrong corridor for a moment, only taking a few seconds to realise it with a raised finger. A tenseness grew in her chest, and she hoped that the Day opposite would be absent, giving her a little time to recover and hopefully not notice her increasingly heavy breaths.

Gosh, was Swift’s breastplate starting to get tight.

Eventually, they turned into the vast, open corridor that forked off to the two princesses’ chambers. While Swift and Nebula’s entrance was relatively small, the opposite side had a grand, double door painted with motifs reflecting both Princesses. The same was true of each half of the corridor and the doors at the midway point.

Fortunately for Swift, only Luna’s door had a guard standing at their post.

“Now I know where we are,” Nebula said, and she pat Swift on the shoulder, making her stop in her tracks. The other guard seemed ignorant of both Swift and Nebula’s predicaments as they and Nebula shared a salute and swapped places in a quick and practised fashion, taking her place before Luna’s door. It wasn’t until the swap-over was complete that the other guard noticed the stiffy poking up beneath Nebula’s skirt, and then they glanced over at Swift. Before they departed, they pat Nebula on the shoulder and then made their way past Swift with a grin aimed at her.

Swallowing, Swift waltzed up to Nebula before setting her spear on the wall beside her. She then pinched two of the armoured plates on her gilded skirt and lifted it up, showing off the puffy lips tucked into a pair of soaked panties. All she managed to get out was a weak and whining, “Please.”

Without looking away, Nebula set aside her spear and helmet and reached down to her armoured skirt, where she found the clasps that held it tightly around her hips. With a few clicks, she dropped the garment down to her knees, letting that soda-can thick horsedick bob before her.

Swift’s heart raced in her chest, threatening to pop out of her ribs. Was she really going to do this? Satiate her need right where the Princesses walked instead of in the barracks or a flop house?

“You good, little bird?” Nebula asked, looking up at Swift. She brought a hand around Swift’s waist, fingers fiddling with her skirt too. “Never seen a mare that ready and worked up in my life, but then I don’t get the opportunity much, so…”

So close, and Swift could smell more than Nebula’s arousal. Her general odour, a faint whiff of sweat and soap from a morning shower immediately following exercise.

With one step forward, Swift pulled Nebula’s head into a kiss, using her height advantage to shove Nebula up to the wall with a thud.

Nebula must have taken that as permission, as she quickly got to work fiddling with Swift’s armour, only to be stopped by wandering hands. “Keep it on,” Swift managed between one kiss and another. “Need to have deniability...”

“At least let me take the breastplate off,” Nebula said. “I want to see your girls bounce. If I’m struggling with mine, you’re, well…” She sniffed and raised her hands to Swift’s back, fiddling with the buckles.

“I just want you to… to fuck me.”

Nebula shrugged, fiddling with the buckles and making them click and clink. “I got stipulations, little bird. Take it off.”

Flaring her nostrils, Swift whined and nodded, relenting to the demand.

Despite her shorter stature, Nebula sure had a lot of strength and weight behind her as she shoved her face into Swift’s again, knocking off her helmet as she did to leave those short, golden locks to fall loose around the sides of her head. Swift stumbled backwards, her hooves forced away from under her by the insistent thestral, crossing back from one side of the hall to the other and bumping through the door of their diurnal monarch.

Swift hardly noticed that they did, though the clatter of a breastplate on the floor did catch her attention.

They tripped over a rug in the middle of the room, Swift landing on her rump with her skirt splayed out over her legs and the floor while Nebula caught herself on her hands and knees. The breeze from a nearby open window played across Swift’s chest, the chill teasing her bared nipples.

Nebula was right; having her breasts out was a relief. Despite the custom shaping and padding inside the breastplates, Swift had yet to find one that fit comfortably for longer than five minutes. She had lines on her skin and fur where the metal pressed hard against the padding, and the fur across her chest was matted with sweat.

Not that Nebula seemed to care much, as she crawled over and nestled her snout between those larger-than-average mounds. She grinned while thumbing Swift’s panties down her thighs, her head and shadowy locks framed by the golden rug beneath them.

The room was bright, covered in pinks and yellows like it was imitating a meadow of flowers in the summertime. Swift had only been inside one time before and only as part of her tour to get familiar with the palace.

Now she was inside Celestia’s room, on her ass, with her tits out, while an incredibly attractive batpony considered her options for ravaging the pegasus.

“So, how do we want this?” Nebula asked. “Want me to eat you out first? Play with your tits? I’m cool, however but I want to make sure you’re—“

“Fuck me until I howl.”

Nebula blinked a few times at the interruption, a look of what Swift thought was a mild surprise on her face. A moment after that, she clapped her hands and rubbed them together. “Straight to the point, hm?” She chuckled, baring her teeth at Swift, those sharp batpony fangs.

Oh, to be bitten by those.

Diving down, Nebula disappeared between Swift’s thighs, her ears and mane tickling at the insides of her legs. That made Swift squirm, especially with the warmth of an entire head mingling with the heat of her pussy. It took her all the effort in the world to not wrap her legs around Nebula’s head and keep her there, even as her snout brushed at her most intimate parts, her nose touched her pubic mound, and her teeth dragged those panties down her legs.

By some expertise or some miracle, Nebula managed to get Swift’s panties off her legs without catching on her boots and waggled her eyebrows at Swift. After spitting them out, she wadded them up and threw them somewhere behind her, back toward the door.

No more words were shared as Nebula crawled all over Swift, mouth meeting mouth, breasts-to-breastplate, and after some clanking and lifting of Swift’s skirt, the heat of a fat horsecock rubbed against the fire of a needy mare.

It was well and good that Swift was oh so ready and had been for most of the day. While Nebula spent a few moments thrusting and rubbing her prick over Swift’s cunny, teasing but not quite pleasuring her fun button, she eventually slotted herself in with one heaving thrust that hilted her into the pegasus.

Where Nebula hissed, Swift moaned, and both of them broke the kiss at the same time. One of Swift’s bracing hands flopped onto her belly to follow the subtle bump past her navel. She could fit it quickly, but that didn’t mean it wasn’t tight, that it didn’t make her entire abdomen and chest tingle.

Now that Nebula was in, she began a slow roll of her hips, drawing back gradually to let the flare drag inside Swift, then shunting forward to make their thighs plap together. Again, Swift moaned, but Nebula managed to keep quiet that time.

And the time after that.

And the time after that.

She worked herself up into a rhythm before long, keeping her voice quiet while Swift struggled to keep her thoughts straight. Each rigorous thrust fired electricity through her gut and up her back until her wings spread, and she whined loud enough for her voice to echo through the room.

Sex always involved a lot of repetitive movements, but for guards, repetition was routine, and routine was good. Every fuck, every thrust, it all felt just as golden as the last, just as mind-numbingly needed. Swift simply didn’t care; she was making so much noise since their hips were making plenty as it was.

Nebula seemed to care, though, and she covered Swift’s mouth with a palm, though it barely quieted the noise Swift made. A little growl floated through the thestral’s throat, a wordless warning to stay quiet. Swift heeded it as best she could, bringing her shrieks down to mere yelps, better muffled by the hand.

While Swift never got to see fat and heavy balls between Nebula’s legs, she felt them plenty as they bounced off her ass. Hopefully, their size and firmness would serve as an indication they would satiate her need, the fucking ache in her womb. The objective of their fuck session wasn’t Swift’s pleasure necessarily, but just to get fucked.

Swift hoped it wouldn’t be too much longer as Nebula struggled to keep herself quiet as her thrusts turned jittery, less stable. Little huffs and growls escaped her maw, joining the increasingly high crescendo Swift was eager to reach. Meanwhile, something about the knot inside made the subsequent drags out harder, a little uncomfortable.

It wasn’t something to worry about three fucks later. Nebula’s final thrust came with a heavy pulsing up and down her ramrod and a rhythmic clenching of her balls where they brushed up against Swift’s ass.

Each clench was married to a sudden increase of heat in Swift’s womb, and while the first two were filling, quickly satiating the craving to be bred, the third was a little much. The fourth brought a tightness to Swift’s waist, and a fifth bulged it out a little.

The sixth was like the ribbon on top, ensuring Swift’s abs were all but invisible.

The two remained there, panting heavily and staring down at their bodies. A few more spurts didn’t plump out Swift more, instead squirting virile gunk over both their thighs. However much time passed as they lay there, Swift wasn’t sure, but she savoured the relief in her belly the entire time.

Eventually, Nebula pulled Swift close, and she kissed her cheek with a chuckle. “Mind is finally clear,” she said, and very, very carefully, she pulled herself out of Swift’s cunny, leaving her winking flower to drool cum out onto the floor, over her thighs.

Swift swallowed hard. Onto Celestia’s floor. Her rug. That was probably more than Swift might hope to earn in ten lifetimes.

Nebula winked at Swift and hiked her armoured skirt over her hips. “Got a job to get to, little bird. And you got a shower you better hurry to.”
