What if the Primarchs were Women?

In the galactic west of the Milky Way Galaxy lied Segmentum Ultima. Of the territories reclaimed by the nascent Imperium of Mankind, Ultima was both the most vast and volatile. It was home to some of the greatest wonders of the galaxy, such as the uninhabitable galactic core, the super-massive black hole that was the Milky Way's dark heart, and the 500 Realms of Ultramar. Yet, with each civilized world, there seemed to exist just as many worlds that were near unfit for human life. These planets, known to the Imperium as Death Worlds were for a variety of reasons extremely hostile to all, save the hardiest of lifeforms. Some has atmospheres with gasses that could burn through lungs like acid, others with local fauna and flora that made a single night there more dangerous than even the most hectic of battlefields, and some still scarred from superweapons used during the infamous Long Night. Among these many worlds, one in particular was known far and wide throughout the Imperium. A planet whose superheavy satellite had caused its tectonic plates to nearly tear itself apart, creating vast and constantly tumultuous volcanic activity that pumped molten rock in quantities to rival oceans and whose constant belching of ash and soot blackened the sky and denied them nearly any light from the sun. This planet was known only as Nocturne, and to most of the galaxy, it was a Death World to rival all other Death Worlds. Yet to a select few, Nocturne was more than another Death World. To them, it was home.

And counted among these few was Vulkana, Primarch of the 18th legion, her Salamanders.

Vulkana, taking in the sight of her home world. Admittedly, Nocturne was not a particularly scenic world, not in the same vein of Macragge or Prospero, and certainly nowhere near the majesty of the Imperial Throneworld of Terra, but still, Vulkana was glad to be home. An incredulous thought to most, no doubt, considering that Nocturne was a plagued by near-perpetual tectonic and volcanic activity, ash clouds, darkness, Firedrake Salamanders and raids from the insidious Dark Eldar, but it was her home regardless. She had been raised here, led it to a new age of prosperity, reforged her daughters into a force that could safeguard humanity forever. Perhaps when the Great Crusade finally came to an end, she could retire here. The humble life of a blacksmith or farmer grew more and more tempting with each passing day. Until then, this brief reprieve from conflict as her legion came to oversee the newest batch of neophytes perform their final test. When Vulkana retook command of her errant daughters, she – like most of her sisters – took the chance to reevaluate their tactics and traditions. Included among this reassessment was introducing a new test to cement their recruits inclusion into her legion: hunting down one of the dreaded Firedrake Salamanders of Mount Doomfire, the very same drakes that her legion derived its name from and the very same beast she hunted alongside her mother when the Empress of Mankind came to reclaim Vulkana for her Great Crusade.

And this latest trial had been a rousing success. The facility was buzzing with activity as the surviving neophytes were loaded onto the awaiting thunderhawks, carrying their pelts of their kills over their shoulders. From here, they would be taken to the fortress-monastery on Prometheus, Nocturne's massive and only moon, to join the already existing pelts decorating the halls. Vulkana wouldn't be joining them on the return trip, however. Now that she was home for the first time in ten years, she was going to enjoy her remaining day on planet before she was recalled back to the Crusade. She had planned this small sojourn for many months, ever since the aftermath of the Ullanor Crusade. Her mother's decision to return to Terra for the time being had been surprising, though it was what came after that left Vulkana feeling uneasy. Was Isis the best choice for Warmaster? Probably and Vulkana was willing to admit as much. Still, she had never felt as close to Isis as some of her other sisters. She didn't outright disdain the 16th sister as much as she would to someone like Areia or Curze, but something about Isis had always left Vulkana with her hackles raised. Maybe some time on her home world would help her get her thoughts straightened out before she went back to the Crusade.

Vulkana knew how she was going to spend this brief time off too. Her newest daughters had just finished recreating the event which let to her joining the Crusade and she planned to do the same. It was through the hunting of one of the great Firedrakes that Vulkana first got an idea of what kind of person her the Empress of Mankind was – or at the very least, the kind of person she wanted people to see her as. Vulkana was neither stupid nor naïve, no matter how many times the butcher Curze claimed otherwise. Her mother's actions on that day, forfeiting victory to save Vulkana's life had not been entirely altruistic. Reclaiming one of her generals was far more important than winning a contest. Had Vulkana been anyone or anything less than what her mother designed her to be, then she doubted the Empress would have gone out of her way to perform such an act. Even then, she couldn't make such a claim in absolute certainty. Her mother was a puzzle to her and her sisters. There were times when she acted exactly as one would expect a mother to act, equal parts nurturing and reprimanding as the situation calls for it. Other times, however, it almost seemed like their mother didn't even like them. Again, if it was Curze or Areia, Vulkana could almost understand. What had happened at Nikea and later at Monarchia, though…

She shook her head. No, she was supposed to clear her thoughts on this trip, not muddle them further. Leaving the spaceport, Vulkana started making her way toward her own the Mount Doomfire. She had a hunt to prepare for.

What was unknown to Vulkana at the time was that at that same moment, the Daemon Prince Baren was in the midst of his own hunt. This time, however, he wasn't hunting for a Primarch. Like Vulkana and her Salamanders, Baren was hunting one the great Firedrake Salamanders of Mount Doomfire. Why was he hunting a salamander? To use as bait when hunting Vulkana, naturally. Baren was no fool, as a Daemon Prince, he would survive any conflict gotten into with the Primarch. Conflict was not his priority, though, subjugation through orgasmic sensation was. Out of three (really four) primarchs he had encountered so far, Vulkana was the only one where direct conflict could only end in her death. He would need to exhaust her first before helping her… relax. And so, here he was standing over a broken and beaten Firedrake on the edge of a magma-filled lake within a subterranean grotto. It had taken some time to find a salamander of acceptable size and strength, but he had done it. Wrestling the beast into submission had been a fun, if fleeting distraction, but now it was time to return to work.

"Don't be afraid, little one," he said to the wounded salamander with a smirk. Raising his arms, Baren began manipulating the arcane forces of the Immaterium, his six-fingered hands crackling with hellish energy. "I will reshape you anew, stronger and greater than ever before. Strong enough to lay low even a daughter of Revelation." Beneath his baleful gaze, the salamander's broken magma-scorched body began to shift and twist. Broken bones knitted and were shaped anew, bleeding flesh seared shut and muscles grew. The foul, Slaaneshi magics affecting the salamander left it screeching and wailing, but to Balen it was the music of the Dark Prince made manifest…

Vulkana hiked up the path leading up to Mount Doomfire, using her hammer Urdrakule as a makeshift walking stick. She had forgone her power armor in favor of a simple and traditional panoply made from salamander hide. The dark green, scaled shirt left her arms bare, exposing her dark ashen flesh to the turbulent winds of shoot and the chill that came with it. Despite what one might assume, Nocturne was not a warm planet. What little warmth and light the planet had came not from the sun, but from its geothermal belly deep below the surface. Perhaps she should invite Runa to come with her next time she returned home. Trading snow for ash might be a change of pace for the Wolf Lady, but her sister might enjoy the chance to hunt a salamander. Runa had been… very withdrawn lately. It was a startling change from her sister's usual boistering, especially recently after she spent several weeks crowing about the Edict of Nikea.

A low, rumbling sound from up ahead broke Vulkana from her reverie and was briefly surprised to see that she had reached the mouth of the cave system already. The innards of Mount Doomfire was a labyrinth of winding tunnels made from smooth walls of volcanic rock. It was in these tunnels that the fearsome Firedrake salamanders made their home. Gripping her hammer tightly, Vulkana entered Mount Doomfire. She wandered through the twisting and dimly lit cavern, occasionally passing the bloody remains of the salamanders her neophytes had slain …and on occasion, those who were felled by the salamanders themselves. It was an unfortunate sacrifice, but a necessary one. Only those who could best the firedrakes deserved to take their name and join the ranks of her legion.

It didn't mean she had to like it though.

As she delved further and deeper down into the mountain, a thick haze permeated through the air. Such a sight was to be expected, given with how much volcanic activity there was on Nocturne. Vulkana wasn't worried, her enhanced physiology made her all but immune to the worst effects of the toxic fumes. Still, a part of her couldn't help but think that the fumes looked... off in some way. In the dim lighting of the tunnel, they almost looked pink. Another rumble from deeper within the cavern retook her attention. Vulkana continued deeper into the tunnel, an anxious heat pooling in her belly, until at last she reached what may very well have been the heart of Mount Doomfire. The tunnel exited out into a massive underground grotto, lit only by a massive lake of molten magma, pillars of toxic ash bellowing up into vents high above. The Primarch of the Salamanders barely registered her surroundings however, all her attention was focused on what was lazily floating in the center of the lake.

Lying on its belly atop of the lake of molten rock was perhaps the largest and strangest looking Firedrake that the Primarch had ever seen. It was a truly massive beast, larger than even the salamander she had caught during her fateful meeting with her mother. It did not possess the dark green scales typical of such drakes, however. Instead, it's hide was white as bone and on its back were two rows of eyes, large pink eyes glancing and blinking all about. Its serpentine body ended in three long, winding tails and on its head were a pair of horns more like some brazen bull than a drake. Though initially startled by the drake's strange appearance, Vulkana quickly shrugged it off, and eagerly gripped her hammer. What a prize this mutant will be. By the time she reached the edge of the lake, the mutant salamander had seen her and swam to the shore, ready to meet her challenge.

The drake erupted out of lake, forcing Vulkana to dodge the raining magma. As she leapt out of the way of falling debris, one of the salamander's three tails knocked her out of the air, causing her to crash against the walls of the cavern. The force of the blow nearly knocked the wind out of her, but Vulkana recovered quicky. With hammer in hand, she charged the twisted drake, nimbly parrying another swipe from its tails. Turning to properly face her, the salamander reared back its head and snapped forward, jaws stretched wide to sinks it teeth into her. With a swing of Urdrakule, Vulkana knocked to drake back once, twice, three times! In quick succession. Just as she thought she had the salamander on the backfoot, the drake slipped under her fourth strike and thrusted its head forward, attempting to gore her with its horns. Though Vulkana managed to avoid being pierced, the blow sent her flying backwards, her hammer leaving her hands. As she attempted to reclaim her weapons, she was knocked back again as the salamander struck her with a heavy blow from its three tails. The hit shattered her armor, leaving Vulkana's chest bare as she ran for her hammer. Though the salamander attempted to get one last hit in, it was too late. Snatching back Urdrakule, Vulkana slammed the hammer into the beast's skull, cracking it a sickening crunch. The salamander reared back, attempting to shake off the blow, but she refused to let it recover. She swung again, bashing the drake's head to side, knocking loose razor-like teeth with her blow. Again, shattering a horn into chunks of blackened ivory, again, blood dripping from gashes across its face, again, the salamander collapsed to ground, wounded, bleeding, and broken. Staring down at the albino firedrake, Vulkana raised Urdrakule high above her head and brought it down. The salamander's skull shattered upon impact, leaving Vulkana the victor.

Panting, Vulkana let Urdrakule slip from her hands and fall to the ground. That fight… had taken more from her than she had expected. Still, she was very pleased. She had slayed what may have been the largest salamander in Nocturne's history. It's hide would hang from the ceiling of her monastery and be an icon among her chapter for millennia to come.

Clap…clap…clap…

"Well, I must admit…I am impressed." Vulkana turned, startled to hear at first, a slow, sardonic applause and then a voice, a man's voice. At the mouth of the grotto, blocking the path leading back to the outside was some type of man, a handsome man, but one with light purple skin, a pair of great, leathery wings, and horns like that of a bull. It was his face that grabbed her attention the most, however. It was a very handsome face certainly, but a cruel one as well and it reminded her all too much of the faces of the Dark Eldar who came in the night and tormented and stole away the innocent souls of Nocturne. When the man stepped closer, Vulkana instantly took a step back.

"Are you another of those monsters the Eldar cook up?" She asked. Glancing around told her that her hammer was closer to him than it was to her. She could run for it, but there was still a chance he might reach it first.

"Those has-beens?" The strange man chuckled at her question. It wasn't a friendly sound, more like someone laughing at a precocious child followed by a condescending pat on the head. "No, I'm Baren and I'm what Vect checks under his bed for at night."

Vulkana didn't know who this 'Vect' was, but had heard Eldar mention his name in passing. The man – Balen – walked closer and Vulkana continued backwards. "S-stay back!" She demanded, trying to keep her distance from this unknown entity. She was panting, breathing in more and more of the strange pink vapor, sweat running down her ashy skin. She walked back on shaky legs until she backed into something broad and firm behind her. Vulkana gasped as a familiar pair of thick, pink arms wrapped around her waist from behind, eyes widening as she saw a second Baren grinning down at her.

"Don't be like that." The doppelganger crooned, pulling Vulkana's curvy, shivering frame against his body. Her breath hitched as she felt something big and firm press against her big ass. "We just want to have a little fun." The original Baren stalked forward, closer and closer, until he was right in front of the primarch, Vulkana's huge, dark breasts pressed flat against his chest. Vulkana flushed darkly as the men pressed closer around her, their leering faces looming over even her towering frame. She shook her head, burning red eyes wide as the Baren behind her reached up and seized her massive tits in his mauling grip. She clenched her teeth and groaned as the Baren in front of her snatched her wrist and led her hand down to his groin, to feel the bulge starting to creep down his pants leg. He felt…big, and that was understatement. Her head was spinning, her ample chest rising and falling quickly as she tried to compose her thoughts…

"M-my mother will destroy you," she whimpered.

…But it was useless. Things were moving too quickly for her to keep up, and when the second Baren pushed down on her shoulders, she went to her knees with a shocked little gasp. "Hmmph, please. Do you honestly think she'll even notice?" They were already opening their pants, already tugging them down along with their underwear. She bit her lip hard and groaned pathetically as they fished their…

…their giant, hulking cocks…

…out of confinement.

These men were hung beyond belief, toting cocks over a foot long while semi-flaccid. Vulkana reached up to grapple with them, just to fend them off from poking her in the face! It was inevitable that she'd fail: the daemoncocks in her hands were throbbing and pulsing like crazy, making her whimper with their sheer enormity. Finally, they started to poke at her cheeks, pushing her lips outward as she swam in a daze of musky aphrodisiac.

"She looks pretty cute like that," said one of the Barens, taking hold of Vulkana by her hair. "I can't wait to see all the other faces she can make…"

He stepped in front of her and prodded his cockhead firmly against her mouth. Vulkana groaned, then started to open her mouth wide, letting her tongue slip over the brim of her lips. The Daemon Prince chuckled as she started to surrender, and he guided his cock into her mouth slowly. "Say 'aaaah'," he said.

Vulkana whined as that cock entered her mouth, flattening her tongue against the floor of her jaw! She flickered and rolled her tongue against the musky cock until his tip prodded the entrance to her throat, and only then, as he tightened his grip on her hair, did she start to bob her head.

"Aww, that's cute," he said as she suckled on his massive, throbbing cock. "But I don't think you get what kinda guy I am. Here – let me show you."

Before Vulkana could do a thing about it, he yanked on her hair and jerked his hips forward, thrusting his obscene cock into her throat. Her eyes shot up and back and she gagged pathetically as her neck bulged around his hellish rod. His counterpart chuckled at the sight of Vulkana struggling and squirming, throat speared on a truly massive cock, patting at his legs with her hands.

"Look at her go," said the Baren who hadn't yet gotten his dick wet, instead jerking himself off as he watched Vulkana choke and slobber. Drool poured off her tongue and dripped down onto her vast cleavage as she tried not to go crazy from the sensation of having her throat so thoroughly stretched. She gagged and coughed and spluttered, but all she was doing was lubing up his cock for future use!

Once he was good and satisfied, he leaned forwards, squeezed her head, and started to swing his hips hard and fast. Gaghk, Gaghk, Gaghk, Gaghk! His strikes landed hard and quicky, showing no mercy to the Primarch. Vulkana Gaghk, Gaghk, Gaghked on his daemoncock, her burning red eyes flying back as her neck danced in and out, in and out around his deep-delving cock. Her tongue flapped on her chin while her tits bounced on her chest, unable to fight back and barely able to endure the hardcore throatfuck!

"This is great," the first Baren hissed as he squeezed her hair even tighter in his fist. "I knew she'd feel good, but I had no idea how good."

"The quit stalling and give me a turn," said the second Baren, clearly annoyed at having to wait.

"Yeah, yeah. Just…one…minute…!" The copy fucking Vulkana's throat growled and started to slam her even harder, even faster, wrenching at her poor, abused throat with his obscene monstercock and slapping his balls against her chin and neck! Each spluttering thrust made Vulkana's mind blur a little further out of order, made her eyes glaze over and her back arch. She was totally losing it, gagging and gaghking and gurgling loudly on the Daemon Prince's titanic, thrusting fuckrod! The end was coming – or at least, the first climax – and all she could do was rock back and forth on his stupidly huge dick---!

"Hnnnghh…!"

He tensed up as his cock throbbed inside her – and then as he unleashed a giant, virile load down Vulkana's throat. Blast after blast of thick, hot seed flooded her belly, cum spurting from her mouth, overwhelming her with the unbelievable amount of cream being pumped into her body. She clutched at the Baren-copy's legs as he filled her with his monstrous load, her tear-streaming eyes wide with disbelief, her tongue flattened between her chin and his huge balls. There was little she could do but twitch and gag on his twitching cock as he dumped the last few dribbling ropes down her throat…

…before pulling out, all at once!

GAGHK!

Vulkana coughed up a thick river of cum from her mouth, all over herself! By the time she was done, her massive tits her streaked and drenched with thick, white cum.

"Poor girl," said the Baren who had yet to enjoy her holes. He lifted her up straight by her hair, and with his free hand, he wrenched away what little remained of her armor. "Should have gotten your power armor, shouldn't you?" He mocked, before slapping his girthy monstercock between her fat tits and squeezing them together around his meat. He started to rock his hips, fucking her tits to get himself nice and warmed up, prodding her chin and cheek with his cockhead each time he rocked forward. Vulkana could only groan and wince against his constant thrusts, turning her face aside so she didn't have to look at him. As if he'd let her, he clutched her chin and made her look at him, his onyx eyes maintain contact with her ruby ones as enjoyed the pillowy texture of her rack.

"I'm gonna fuck you up," he purred, his voice almost affectionate, before tugging his cock out from between her big tits and slapping her across the face with his oversized cock! Vulkana grunted falling back, and he fell on top of her, roughly stripping away her leather skirt, panties, and boots so she was left completely naked! His cockhead drilled up tight against her wet pussylips while he clutched her muscular thighs, holding them wide apart and ready for his insertion. Vulkana gasped and yelped helplessly as the hellish stud got into position…

"W-wait!" she cried. "I'll…lose my mind…!"

Baren arched an eyebrow. "That's the idea," he said, before surging forward and driving his massive cock into her pussy! Vulkana yelped as he bulged her tight, flat belly around the shape of his cock, and started to thrash her with heavy thrusts she had no hope of enduring. She squealed and moaned as he clapped her soaking pussy into a stupor, pounding her with blinding speed, making her tits bounce around and her thighs jerk in his hands. He pushed her legs up higher as he leaned further over her, intent on breaking her mind and stretching her pussy out beyond belief. "You have no idea how much fun breaking you and your sisters is," he confessed as he clobbered her cunt, Smack Smack, Smack, Smack! He pumped her with unbelievable speed, fucking her like she was some hive-city whore than a war lord. His balls clapped down on her asscheeks, and how he'd managed to stuff every last inch of his cock inside her, she had no idea. All that mattered right now was the unbelievable pleasure wracking every inch of her body, making her whimper and squeak and whine her bliss out to the world. She was totally losing it, gasping like a slut as she took the roughest fucking imaginable, her legs bounding back and forth in her semi mating-press, her tits beating together, her tongue swirling outside of her open mouth…!

The daemon stud fucked on, pounding toward the finish line with a callous disregard to her safety. He didn't care if he permanently reshaped her pussy to better fit his cock. If so, all the better!

"G-Gonna…fuck…I'm gonna-" the Daemon groaned as he ruined Vulkana, SMACKing his gigantic cock in and out of her at high speed, refusing to let up one bit! His monstercock demolished her cunt, beating his balls of her asscheeks again and again and again and-

He plunged every last inch of his ridiculous member into her balls-deep, and growled as he unleashed a gargantuan flood of seed into her womb! He blasted her with unrelenting force, jerking his hips as he came, unable to stop himself. The pleasure was overwhelming, making him tense his muscles and snarl in bliss as he blasted more spunk into the Primarch. Cream gushed from her gaping cunt and spread out into a widening puddle on the floor. She stared up in a daze, gurgling in disbelief, her eyes wide and lips parted in a soft, panting 'o'.

That was when the two Barens picked her up, hauling her into the air and pinning her tightly between them. One of them shoved his still-hard cock back into her pussy, and the other one stretched out her asshole, making her shriek in shock and pain…and pleasure, of course. They crushed her between their bodies, making her whine as her sensitive tits were pressed flat. Then they started to thrust, slamfucking her pussy and asshole with merciless beats of their hips. They ruined her more with each repetition, pumping her holes like she was some kind of slutty, sucking, bimbo. Her eyes lolled in their sockets and her tongue flopped out, drooling cum onto her quaking boobs from her earlier throatfuck as she bounced in the two studs' arms. There was nothing she could do but hold on! They demolished her more with each successive beat, driving her mind into a heaven of pure bliss, making her whimper and squeak and tremble…

Until the end came.

The two studs pumped balls-deep inside her and unleashed their loads, giant torrents of cum that flooded her to the brink. She clung pitifully to her tormentor, arms and legs wrapped around their shoulders and waists, gargling and groaning, curling her toes as the bliss threatened to overwhelm her, to drown her under its tides. She couldn't hope to hold on like this! Too much pleasure, all at once. She screamed as she twitched…tensed…

…and came.

Vulkana squirted on their giant, throbbing cocks like the sluttiest girl in the galaxy, clenching her cunt and asshole around their hellish girths and prolonging their orgasms with the friction. They kept pumping even despite this, beating their daemoncocks into her, making her whimper and squeak and mewl as they brutalized her pussy and asshole beyond belief. Her tits scrubbed against one Baren's chest while the other grinded himself forcefully into her back, never giving her one second's reprieve.

They kept on grinding, kept pumping, as she gasped and groaned…until at last, they pulled out, inch by inch, removing their vast cocks from her tight-gripping holes and letting them spray jizz in pressurized bursts!

They dropped Vulkana to the ground unceremoniously, where she lay rubbing at her pussy pathetically as cum spilled out. "Unnngh…Ulghhh…" She writhed and squirmed like an unrepentant slut, unable to raise her voice or even formulate words in her dizzy, slutty mind. The symbol of Slaanesh appeared in stark white on her right bicep, contrasting beautifully with her dark skin.

"Haaaahh…"

The two studs crossed their arms and grinned down at her, amused by her state of total, obliterated pleasure.

""Good work,"" the Barens said as one, before remerging into one singular Baren with a flash of pink light. He stretched, feeling much better now that he was whole. He didn't like sharing, even with himself, but quarry like Vulkana warranted extra precaution. The black head of the Salamander appeared on his own right bicep. Behind him, a tear into warp-space manifested. As he turned to leave, he took the time to call over his shoulder. "Oh, and feel free to keep the salamander. You've earned it."
