What Do You Do With a Sexy Xenomorph Early In the Morning?

Deep beneath Canterlot, within its little-known crystal caves, several figures darted through the darkness, one sinuous and sleek, covered in chitinous armor and possessing a magnificently crested head, the rest large and bulky, with fur and horns or wings, each covered in either golden or navy armor.

“Stop right there, changeling scum!” one of the pursuants cried, lobbing his spear at the much swifter figure in front. Vex cursed to herself, using her superior agility to rebound around the pillars supporting the caves and leap through the air with a natural grace that would make even the greatest of parkour practitioners weep in envy. As she leapt, she made a point of flashing her rather generous assets at the guards, teasingly waving her rear in their general direction.

Several of the less experienced guards froze up at the sight of her bountiful, bouncing, barely-armored, and completely nude behind, falling into heaps of aroused and embarrassed stallionhood. The more experienced guards kept their composure, continuing the chase even with their diminished forces.

A sad fact was that many of these more experienced guards were also female.

Vex, by this point, was far ahead of her pursuers, and had stopped to take a breather to assess the situation. She panted, each breath sending her breasts into a glorious, heaving bounce. Sweat beaded along her unarmored bits, giving her charcoal colored skin a sensual gleam. A long, pitch black tongue swept over maroon lips, a teasing smirk forming. Vex chuckled to herself, a low, husky tone guaranteed to send shivers up the spine of any straight male within earshot.

“Oh, well~ Looks like they won’t be able to keep up~” She giggled, leaping away into the darkness of the deep caves, leading the company of guards deeper and deeper into her natural element. Visibility lowered until the guardsmen were forced to light their torches and light spells, casting a flickering, orange glow on the surroundings.

Vex circled just beyond the range of the light, hoping that the guards would just leave her be. After all, she’d just been minding her own business. That is, until some lucky pony spotted her slinking through the shadows and called down the guards on a changeling hunt.

Unfortunately, as luck is a fickle bitch, disaster struck on her end. Her footing slipped and a tiny pebble came loose, bouncing off of one guard’s helm with a quiet plink! Instantly, a dozen light sources were fixed upon her position, spells and spears and arrows already flying at her. Vex fell, twisting in midair to dodge the worst of the spells, until one particularly well aimed concussion blast caught her in the side of the head, knocking her unconscious. Then she somehow slammed, bare womanhood first, into a lucky/unlucky guard’s muzzle, cushioning her impact and knocking him out, causing the both of them to fall into an incredibly compromising position.

“The hell is this thing?” Sergeant Tower Shield muttered, examining Vex’s form with a gaze made of three parts scrutiny, two parts paranoia, two parts idle questioning, and three parts lust. If any of her guardsmen noticed her eyes lingering over certain parts of the strange being’s anatomy, they wisely said nothing, only pausing to make sure that the crested creature was bound and restrained according to procedure, with extra bits tacked on to secure the thing’s tail.

“I dunno ma’am, but it doesn’t look like any changeling we’ve ever seen. Doesn’t even look like it’s got eyes.” Tower Shield’s second in command, Iron Soul, examined Vex with the same gaze as his commander, except with seven parts lust. She– and the being was most definitely a female– had an incredibly large pair of breasts, perhaps even rivalling those of Princess Celestia herself. Even though she was armored, the sheer skimpiness of it served only to heighten the sex appeal just oozing from her form. A cough interrupted Iron Soul’s shameless ogling, startling him back to reality, just now noticing the slight bulge protruding from underneath his armor. He blushed, desperately trying to keep his composure even as several of the female guards tittered at his inattention. Tower Shield glared at her SiC, slapping him upside the head with a gauntlet covered hand. “Get your act together, Corporal. We came here to track down and imprison a changeling, not for you to get all flustered over a naked whatever-the-hell-this-is. Come on, the Princess is going to want to hear this.”

Swiftly stuffing the female creature into a large, reinforced body-bag, the troops prepared to move out. Private Long Haul sighed, slinging the body bag over his frankly titanic frame. “Why the hell am I always stuck on prisoner transport?” he whined, shifting the bag to rest more comfortably on his back. His partner, aptly nicknamed Bonecrusher, patted him on the back, as if to say ‘better luck next time’.

The guards traveled through the winding labyrinth of caves, coming back to the surface shortly after. Tower Shield shook hands with the other Sergeant in the troop, Night Guard Sergeant Slip Stream. “Well, Tower, the night guard thanks you for your help. If you ever have a problem during your shifts, feel free to call on us.”

“Of course, Slip Stream.” Tower Shield called over her troops, and the blessing of unicorns took off, marching in perfect unison. Slip Stream beckoned Long Haul over, blinking rapidly as the sun reflected off his armor and into her slit-pupiled eyes. “Alright Long Haul, we’d better get this… thing to the dungeons for processing. How’s your mobility?”

Long Haul flapped his rather disproportionately small wings (though they were still titanic compared to most other pegasi) a few times before giving his superior a thumbs up. “I’m all good, ma’am.”

“Good. Night Guard, move out!”

Twenty pegasi took to the air, each clad in gleaming navy armor, the largest of all carrying Vex’s temporary resting place.

Vex awoke, groggy and slightly aroused, as was her normal. She shook her head and attempted to gain her bearings, her helm-covered eyes scanning the room in thermal, regular, ultraviolet, and in magical sight. Nothing out of the regular greeted her eyes, no suspicious splotches of color dotted her or her nether regions, as far as she could tell, so she hadn’t been raped while unconscious. She sighed, taking stock. Her hands were shackled behind her back, her calves shackled to the floor, she had a ring gag in her mouth, and there was a collar that chained her into a submissive position. If she didn’t know better, she would have assumed that she was in some sort of sex dungeon.

A few minutes of boredom and fruitlessly rubbing her thighs together later, she heard a door open, her magical sight registering it as so bright it was as if the sun had entered the room.

She wasn’t wrong, not really, as Princess Celestia had walked in, bearing all the finery and effects that a diarch should ever have. Celestia strode over with the approximate authority of the sun in the middle of summer, bearing down on Vex like a particularly curious warm front. Just as staring at the sun is bad for the eyes, so was staring at Celestia with magic vision. So, Vex switched back to normal vision, finally blinking the spots from her eyes as Celestia stopped right in front of her.

“So, what manner of creature are you?” she asked, crossing her arms under her prodigious bust, idly noting that said creature’s breasts were almost as large as her own. Vex couldn’t answer, due to the ring gag forcing her mouth open. Her only reply was a waggling tongue, extending nearly two feet from her lips. Celestia blushed in embarrassment, swiftly removing the gag and allowing Vex to finally close her mouth for the first time in hours. After working her jaw around for a few seconds, Vex answered in a raspy tone, “I’m not a creature, lady. I’m a person, same as you.”

Celestia shrank back some, apologizing for the slight. “I apologize, I misspoke. What I meant was, what species are you? I’ve never seen somepony… or rather, someone like you.” Her wings fluttered a little, showing the embarrassment her face did not.

Vex shrugged as much as she could, “It’s fine… I guess… Hey, as long as I’m in this position… could you come a little closer?”

Celestia hesitated for a moment, then stepped forward, barely a foot away from Vex now.

“A little closer.”

A half step forward. Now Celestia’s crotch was hovering directly in front of Vex’s face. “What exactly is the purpose of me being so close?” she asked, almost ready to step back and deny whatever Vex was going to ask straight away.

Vex smirked and, in a single swift movement, speared her tongue straight through Celestia’s dress and into her unprepared cunt, swirling the appendage around and smearing natural aphrodisiacs all over the inside of Celestia’s now dripping vagina.

“A-Ahh~!” Celestia’s back arched in surprise and ecstasy, tongue slipping from her mouth with a surprised moan. Vex smirked into Celestia’s crotch, adding little flicks against the entrance to Celestia’s womb every few seconds. As the tongue-fucking continued, the Princess of Equestria fell to her knees, hands coming up behind Vex’s head in an attempt to jam the tongue even deeper into her dripping pussy.

A flare of golden magic tore away the lower half of Celestia’s dress, the violent action causing her breasts to bounce free. Another flare of gold ripped apart Vex’s restraints, allowing the Xenomorph to run her armored hands over Celestia’s ass and waist, groping and squeezing the white furred mare with reckless abandon.

As Vex groped and stroked Celestia’s ass and thighs, her tongue retracted from Celestia’s honeypot, eliciting a disappointed moan from the nearly insensate ruler of Equestria. Not to disappoint further, the tongue slipped back out and began teasing Celestia’s asshole, licking around and inside the tight ring of muscle, drawing gasps and near-orgasmic moans once more.

Unseen by both, Vex’s throat and hard palate shifted, alien biology coming to a full expression as a fleshy appendage descended from a now opened slot in her hard palate, swelled, and jammed itself straight into Celestia’s twitching pussy, spreading it with incredible ease and slipping all the way in to tease her cervix. The appendage thrust in and out of Celestia’s aching twat, flesh pulsing in time to the beat of Vex’s heart.

Celestia was in heaven, her marehood was filled with a cock, unorthodox as it was, for the first time in over a century. Her ass, she never thought about using it like that before, was being swirled through by a tongue that just seemed to press into every sweet spot she didn’t know she had. Just when she thought that the pleasure couldn’t get even more intense, the cock inside her stilled for but a moment. Inside Celestia, Vex’s cock-tongue split open along its tip, urethra opening and spilling out four squirming tentacles, penetrating deep into Celestia’s womb. The tentacles flailed about in unilateral purpose, stroking and kneading the inside of Celestia’s uterus, driving her to even greater heights of pleasure. Celestia had already gone through several orgasms and didn’t plan on stopping anytime soon.

Vex, sensing this, retracted her cock-tongue and its flailing tentacles, once again eliciting a disappointed moan. She chuckled, low and husky, sending a massive shiver up Celestia’s spine, and aligned their bodies together, jamming both tongues into Celestia’s open mouth, deepthroating and french kissing at the same time. Down below, Vex’s pelvic armor flexed away from her groin, a pair of penises flopping out from their sheaths and swelling to full attention nearly immediately. Vex grinned into Celestia’s mouth, roughly fondling the diarch, stroking her sensitive wings and horn. Both penises, though seemingly rigid, flexed and plunged deep into Celestia’s ass and vagina, filling her like she’d never been filled before. Celestia’s wonderful torment wasn’t over yet, however, as Vex’s bountiful bosom pressed against her own magnificent mammaries. Vex’s nipples were shoved against Celestia’s, both sets of nipples fully hardened and erect. Then, Vex’s nipples did the impossible and spread open, widening out and capturing Celestia’s own, suckling them even as the tiny barbs on the inside of the opening bit in and pumped in even more aphrodisiac.

Celestia’s orgasmic cries grew steadily louder, the only reason why no guards came running was the simple fact that the door had been soundproofed. Clawed and armored digitigrade legs tangled with alabaster hooves as Vex’s sinuous tail tied the pair of unexpected lovers together. Faster and faster Vex thrusted into Celestia, both females crying out in sheer ecstasy as they drew ever closer to orgasm.

With a last, powerful thrust, Vex orgasmed, prompting Celestia into the same. Vaginal fluids sprayed into the air from the pair’s earth-shattering climax as Vex pumped Celestia’s holes full of semen. Even after Celestia’s climax ended, Vex pumped in more and more ejaculate, her tail fitfully spurting out globs of the fluid as well, staining Celestia’s wings. When Vex finished some minutes of orgasm later, she flopped to the side, idly playing with a strand of her own semen, studying the way it contrasted against her charcoal gray skin and shining, onyx armor. Next to her, Celestia lay comatose, leaking semen from her mouth, nostrils, pussy, and ass. Her belly had swollen to the point that she looked almost ready to give birth. Slowly, Celestia’s innards emptied themselves of Vex’s thick cum, flooding the floor in a puddle of semen nearly twelve feet across.

Vex admired Celestia’s figure from where she lay, the diarch’s dress completely shredded by her powerful tail. Vex had to admit, Celestia was an incredibly beautiful mare. A pinnacle of feminine beauty that all mares strove towards. Large, full breasts, wide, motherly hips, thighs that could crack a walnut. Oh yes, there was a definite beauty to her that Vex was unable to match, even with her otherworldly grace and her aphrodisiacs and her suggestive pheromones.

Vex shrugged and grinned, spooning Celestia as the two lay in the sticky puddle of warm, almost steaming semen. She kissed along the back of Celestia’s neck, drawing little shivers and mewls from the unconscious solar deity. With a final sigh of contentment, Vex fell asleep, cradling the slightly shorter Equestrian Diarch in her arms, the pair completely oblivious to the cooling semen staining their forms.
