What if the Primarchs were Women?

Within the vast halls of the Gloriana-Class battleship known as the Vengeful Spirit, Isis Lupercal sat fuming. The Primarch of the 16th Astartes Legion, once called the Luna Wolves and now rechristened 'the Daughters of Isis' had dismissed both her Mournival and her equerry for the evening and now sat alone in the Spirit's command center, her pseudo-throne room. How had everything gone so wrong? she wondered. It started with Ullanor; she was sure of it. All roads seemed to lead back to Ullanor. She had fought alongside her mother – the Empress of Mankind, as well as two of her Primarch sisters, Romilly Guilliman of the Ultramarines, and Tuya Khan of the White Scars to conquer the largest Ork empire the galaxy had ever seen. Their victory should have been a crowning achievement in a Crusade already full of them, if not for her mother. No, all roads didn't lead back to Ullanor, they led to back to the Empress. The Empress of Mankind had announced, while the embers of Ullanor were still hot, that she was returning to Terra and that Isis was to take her place as commander-in-chief of the Great Crusade, awarding her with the title of Warmaster.

Since that moment, however, everything just seemed to be steadily coming apart. The death of her beloved daughter Sejanus, the strange encounter with the Warp-being on Sixty-Three-Nineteen, the conflict with the Interex, and then the disaster on Davin's moon. Isis pressed an armored hand to her chest, where beneath her armor lay the scar from the traitorous governor's sword. She had nearly died there and the only reason she had survived was due to the native's strange ritual performed within the Temple of the Serpent God. Somehow, their tribal faith had succeeded where the greatest of Imperial medicines had failed. She had been comatose during the ritual and in her fugue state, she had a vision. A vision of a future where her mother was worshipped as a god and she and eight of her seventeen sisters had been forgotten. In that vision, she was made aware of the true scope and power of these warp-beings, these so-called 'Gods'.

Miseria, First Chaplain of Aurora's Word Bearers had been attempting to guide Isis into making a pact with these 'gods' and yet she remained on the fence. What did she need the aid of gods for? She had the loyalty of her legion, the loyalty of the army, the loyalty of countless worlds, she didn't need gods to help her in her rebellion. So, here Isis was, stewing in her outrage and beginning to plan out her rebellion. It was here that her isolation was interrupted, but not by any of her legion or the chaplain. To Isis's surprise, it was Aurora Aurelian who strode into her chambers.

"Sister," Aurora greeted pleasantly. The Aurelian's appearance had changed in the time she's been gone. She was not wearing her armor, instead she wore a robe dyed a rich purple color and left very little to the imagination. Her face was tattooed with two lines of strange, unfamiliar text that ran down her eyes like tear streaks, the golden ink contrasting brightly with her dusky skin. "You appear to have recovered quickly."

"Why are you here, Aurora?" Her words were terse, but there was genuine curiosity behind them. Her wayward sister had been quiet for the past 40 or so years since the events of Monarchia, seemingly driven on capturing planet after planet when previously she would take decades to convert them. All Isis knew was that in that time, her chaplains had been restarting the so-called 'warrior lodges' among the legions.

As though she had read her mind, Aurora impishly answered with. "I can't say." She rolled her eyes at the seething look Isis gave her and added. "Is it wrong for me to be concerned about my warmaster's health? Miseria told me of your little 'accident' on Davin."

So Miseria was spying on her for Aurora? To what end? "Many things happened at Davin, sister." Isis admitted quietly. "Many things were revealed to me…about the galaxy, about the Warp…about mother."

Aurora's face softened slightly. "Ah…you've found out then."

"Found out what, exactly?" Isis pensively stared at her sister.

Auroa raised an eyebrow. "That our mother plans to be a god, of course."

It was a confirmation of Isis's fears and validation that what she had seen on Davin hadn't just been in her mind, that the awful truth was that their mother – the Empress of Mankind – was plotting to be worshipped as mankind's sole god while she and her sisters are left in the dust, forgotten, abandoned, forsaken. "You knew?" She quietly asked her sister.

"Not until very recently." Aurora reassured the Warmaster. 

Isis looked at the Aurelian sharply. "Then you know what must be done, for the good of the Imperium?"

"Naturally," Auroa lied. Oh, she knew what Isis meant, but the death of their mother was only one possibility, and a very meager one compared to the paths Lord Baren had shown her. She simply had to steer Isis in the right direction, what Miseria had failed to do. "Of course, two against sixteen aren't very sporting odds, sister."

"The others can be convinced," Isis seemed to be trying to convince herself as much as she was Aurora. "Areia, Kassandra, Morticia, they're practically chomping at the bit for an excuse, and maybe the others as well, Ferra, Tuya, Alphara. They can be convinced."

"Even if they can be, what then?" Aurora asked. She stepped closer and placed a hand on Isis's shoulder. "You know not all of our sisters will be convinced. Runa, Sanguinia, Guilliman, not even you could change their minds."

"We won't need them," The Warmaster insisted fiercely, shoving Aurora's hand away. "We have the love of the army, the Titan legions, the Mechanicum will join the second we offer them more freedoms for their research. We could take Terra in a matter of months."

"Our mother is very strong, Isis. A strong tactician, a stronger psyker and Regalia has been turning the Imperial Palace into a fortress. If you truly are committed to this, you going to have to accept…outside help."

Isis gave her sister a sharp look. "You mean those 'Warp Gods', don't you? I don't need the aid of whatever those things are?"

"Against mother you just might, sister." Aurora calmly retorted. When Isis still looked unconvinced, she smiled. "Perhaps…I could introduce you to one of these warp entities. Let them convince you themselves."

Isis snorted. "You can introduce me to one of these so-called 'gods'?"

"Not one of the gods themselves, but one of their champions. A Daemon Prince, a powerful mortal blessed with the divine patronage of one of the four gods of the Warp."

Isis was quiet for several moments as she mulled the offer over. Finally, she looked Aurora dead in the eyes and said. "One chance. You have once chance to convince me, Aurora."

"One chance is all I'll need." Aurora took her sister by the arm and started dragging her to the Warmaster's private quarters. "Now, come along. We have to get the ritual ready."

Isis very reluctantly allowed her sister to drag her off to her room. "Who even is this so-called 'Daemon Prince', sister?"

"Oh, I think you'll like him." Aurora didn't face her sister and for good reason. The hungry, almost love-struck smile on her face would have surely raised too many unimportant questions. "His name is Baren."

-

"Aurora, I'm starting to have doubts about this."

"Oh. How come?" Aurora didn't look up at her sister, she was too busy finishing drawing up the correct runes and scripture onto the floor.

"Well, these robes for one." Calling them robes was being incredibly generous in Isis's opinion. They hem ended just below their thighs and the top didn't have enough material to entirely cover their chests, exposing deep valley of creamy cleavage. The only saving grace was that it was just her and Aurora in the room. Isis wasn't convinced her pride could have taken any of her daughters seeing her dressed like this. "Why couldn't we just wear our armor? Or regular robes?"

"That's not how it works, sister."

Aurora's overly patient tone was starting to grate on Isis's nerves. "And being armed is 'not how it works' as well, I take it?"

Aurora shook her head and Isis barely resisted the urge to start strangling her sister. "Lord Baren will have no reason to start a conflict, Isis." The Primarch of the 17th stood up and examined her work. The floor of Isis's chambers was now covered in gold paint drawn in a series of twisting and jarring patters lined with sharp, angular runes, surrounded by lit candles. At the center of this labyrinth was the symbol of Slaanesh. The Aurelian smiled gleefully to herself. Oh, she couldn't wait to see Baren's work in person.

"It's finished then?" Isis asked, coming to stand next to her sister.

Aurora eagerly nodded. "Yes, everything's set up perfectly!"

"What happens now then?"

Auroa grinned and stepped forward, standing before the twisting golden runes. She raised her hands up high, and like a priestess before her flock, began her fiery sermon.

"Lórdos Báren, Daímonas Prínkipas tou Megálou Fidioú. Sas kaló edó se aftó to thnitó vasíleio sto ónoma tis ekstatikís anazopýrosis, tis fótisis mésa apó tis orgastikés empeiríes. Apó epithymíes kai peínes pou tréfontai apó pótho kai sárka!"

As Aurora chanted in the strange language, the golden paint began to glow and the symbols appeared to twist and writhe as the candlelight grew brighter and brighter, the flames becoming a dark, flickering purple. The gold shimmered and rose from the ground in a twisting writhing wave before slowly forming into a humanoid shape. As the form solidified, the gold flaked away and Baren stepped forward, standing where the circle once was.

Aurora approached the Daemon Prince with a broad smile on her face. "Lord Baren," she began. "Welcome aboard the Vengeful Spirit."

The Daemon smiled. "Aurora, my sweet, always so welcoming."

Isis stared in silence at the Daemon, not entirely sure what to think. Baren turned and saw her, and his smile grew, revealing many, many sharp teeth. "Primarch Isis," he said, bowing deeply. "A pleasure."

The Primarch of the 16th legion found her voice at last. "You know of me?" she asked, trying to sound more in control than she felt. All of this Warp nonsense was beyond her, and she wanted it over and done with quickly.

Baren's grin turned impish. "Who in the great and magnificent galaxy does not know the venerable Warmaster Isis Lupercal. Even the Gods carry your name on their lips."

"Yes, Aurora has told me about your 'Gods'. So, tell me, Lord Baren, why should I ally myself with the Warp? What can you and your gods offer me in my war against the Empress?"

"The Warp can provide you and your sisters a great many things, Warmaster Isis." Baren answered. He took a step closer to Isis, forcing the Warmaster to look up at him as he came close to invading her personal space. "Legions of deathless warriors, the powers of the Immaterium, the strength to overcome your mother within her own palace. All of this I offer to you, Warmaster."

He stepped closer and Isis swallowed as she stared up into Baren's dark eyes. Wh-why were her legs shaking? He was too close, much to close and practically looming over her. Isis gathered up and her thoughts and asked, "a-and what do you want in return?" Strong fingers slid behind her head, grabbing fistfuls of long, black hair, tugging gently at glossy strands, tilting her face upwards. Baren's mouth found Isis's, his tongue parting her full, pouty lips. A demanding, insistent stiffness prodded in her belly. The sudden mashing of his lips against her own made Isis's eyes widen, the whites visible all the way around her pupils as her chest inflated from the shock and pressed her nipples so far forward they almost tore through the fabric of her robe to get to his skin, throbbing hotly as they scraped against his muscles while she dazedly opened her lips to allow his tongue access to the inner sanctums of her mouth, its fleshy length pillaging her moist pink cavern and lapping away at the sweet tasting juices pooling behind her teeth while her own trembled unsurely before tentatively rushing forward to try and push him away, failing spectacularly as he playfully batted her down before exploring her gums from corner to corner and licking around her teeth.

She was so surprised by all of this, so overwhelmed by the sudden deluge of new sensations, that for at least a second or two Isis was frozen. By the time she registered what was happening, she could feel his hands pulling at the robe wrapped around her. A gasp left her lips as she suddenly found herself pressed against that warm, bare chest, fingers splayed across his pecs as cologne filled her nose. Perilously balanced on one foot and desperately clawing at his bulky frame to try and stay standing, Isis wasn't nearly prepared enough for the thick, trunk like leg that pressed forward and wedged itself between her own while she gave a wordless shout of surprise followed up quickly by a startled moan as her panty covered crotch bumped and ground up the bare skin of his leg.

"Mmmphhh!"

She tried to cry out, but her mouth was so full of the Daemon's tongue that only a muted, muffled moan emerged. Like the dangerously exposed tip of a still charged wire, Isis's pussy sparked as it rubbed against his skin until with a mortified whine she felt her juices beginning to soak into the fabric, outlining the shape of her lower lips and staining her underwear a dirty grey while the rest of her body melted into his arms, legs essentially collapsing and placing more pressure on her thoroughly purring kitty while she scratched at his chest.

"Mmmphhh!"

Isis moved her hands to Baren's chest, trying to push him away. But he was so much bigger than her, it was as if she was attempting to move a Baneblade. Her body had melded to his own with her plump thighs squeezing around his leg, his knee pushed out just beneath her ass cheeks as he reached down her back and scrunched the hem of her robe between his fingers to pull it out out of the way, leaving nothing between the viewers at home and Isis's fat, meaty ass which subtly wobbled with every twitchy jerk of her hips as he forcefully grated her mound against the top of his thigh.

"Mmm…Mmhm…Hmmph!"

In trying to push him away, all Isis had succeeded in going was letting him tug at her robe without resistance. With a mighty yank, Baren ripped it from around her body, casting down onto the floor of her chambers without another thought. Now, without the barrier of the robe between them, Isis could feel Baren's body against hers, his warm skin pressed against hers. She pulled her neck back, finally managing to break away from the kiss.

"Mmm~ schlep, ga~ HA! Mmmmphwa~ STOP!" Somehow through the gasps and moans, Isis managed to pull herself away from the predatory dance of his lips, pink faced and glassy eyed as smirked at her curiously and continued manipulating her lower half to rub against him. "Ah, how dare-" She panted breathlessly only to cut herself off as she felt Aurora press her curvaceous body against Isis's back, pinning the Warmaster between her sister and the Daemon. "Aurora, what are you-?"

"You want his help, don't you Isis?" The Aurelian purred. Isis gasped as Aurora pressed soft, wet kisses to her neck. "This is the price, sister."

Baren chuckled darkly as Isis's look of bewilderment. He rolled a hand of the Warmaster's side, caressing her hip, her waist, the outer flank of her bust. Isis shivered in outrage when Baren's hand reached her cheek, and slipped its thumb into her mouth. It played over her tongue without fear of repercussion, even though Isis looked like she'd bite down at any second. Her nostrils flared and spit seeped from the edges, dribbling down her chin and splattering onto the slopes of her big creamy tits while her juices dribbled down towards her ankles.

"She's just full of surprises, isn't she?" He asked Isis.

"I-you!" Isis's body quaked with indignant rage as the pieces fell into place. "You…you touched her didn't you, you lecher?"

The Daemon chuckled condescendingly. "'Touched her'"? He sneered as he tugged her hair, forcing her to look back up at him. "Use your big girl words, Isis. I didn't 'touch' her. I fucked her. Her… and a few others."

Isis's eyes fell onto Baren's arm, the one that held her by her top knot. On his forearm, images appeared. Familiar images of Hydras, Ravens, Salamanders, and a flaming open tome. Her sister's heraldry…

"Haah…You…you incorrigible thug…" Isis spoke around Baren's thumb, making the taller Daemon chuckle and smile. "You violated my sisters…and now you proposition me? How dare you!"

"You want to be strong, don't you Isis?" Baren asked as the Warmaster gasped and writhed as Aurora's hands drifted low, one's greedy digits spreading the folds of her sister's cunt, the other undoing Baren's belt, freeing his massive cock from confinement. "You need my help, don't you?"

Isis blinked, trying not to let her strain become visible, but it was hopeless; it was blatant, written in her face and body language, her tense shivering. "You…you…" she breathed, then pushed hard against Baren. Baren, amused, allowed Isis to force him backwards, step by step, until he sat – and then sprawled – on the Warmaster's bed.

"Changed your mind, sister?" Aurora asked, a coy smile on her face.

"You be quiet!" Isis called over her shoulder. "If…if we're doing this, it's going to be on my terms." She said as she straddled Baren on the bed, thrusting her belly up against the colossal cock. Her hands wrapped around it, pumping up and down, up and down, from where its base nestled against her cunt to where its broad crown oozed globs of precum against the underside of her tits. Her hips moved in circles as she huffed and puffed with a reluctant excitement that turned her face red, stiffened her nipples, and made her pussy drool.

"Your terms, huh?" Baren drawled, shifting his hips under Isis and gripping the bed sheets. "What do you have in mind?"

"You'll see," Isis said, cupping the outside of her tits and squishing them together around Baren's cockhead, massaging it with slow pumps, milking precum from him…before spreading her tits wide apart and gazing at the strings of white cream that connected them. She glanced at Baren, hummed, and then lifted herself up higher – squatting over the massive cock with her slick, needy pussy against its tip. "As punishment for your transgressions, you will serve as my servant!"

Baren braced himself – and groaned as his cock was plunged into the divine heart of Isis's cunt. As soon as she'd lodged that ridiculous cock inside her, Isis started to bounce, to jerk her hips back and forth, and in lewd circles.

"Oh, Terra…" Aurora murmured, coming closer to watch the depravity on the bed. She was feeling pretty neglected, but her fingers, at least, were having fun toying with her slippery clit.

"Ah! Ah!" Isis cried as she pumped away, bouncing her asscheeks and jiggling her tits over Baren's form. The Daemon gripped Isis's sides as the Warmaster rode his cock, making her lips part in an 'o' of pleasure, her eyes roll partly back, and her body arch in deep, shivering convulsions of joy. "Nnngh…Enjoying this, are you!?" Isis snapped as Baren thrusted. "You'd best savor it, and understand…had…the difference between us!"

With that, she rammed her hips down low and every last inch of Baren's cock was swallowed up by Isis's greedy cunt! Isis punished herself with that colossal dick, driving it into herself without a shred of mercy either for her own cunt, or for Baren's throbbing cock. They both moaned out loud, letting their voices rise through the ceiling and toward the Void as they thrashed and crashed together in sweet throes of bliss. Baren lifted his hips into Isis's descents as best he could, slamming his daemoncock into the Warmaster's tight cunt, making her yelp with each balls-deep pump!

Baren was burning on the inside, barely holding back the urge to turn the tables on this arrogant slut. He wanted to grab Isis, to roll over and fuck her silly until she could never process a coherent thought again, but he allowed her delusions of superiority to be fed. It would make her fall all the sweeter.

"That's right – know your place, Daemon!" Isis howled as she thrust down one more time – and gurgled in orgasm. She squirted powerfully as her cunt clamped and clenched around Baren's daemoncock, wringing every inch of his member from base to tip. Baren was pushed over the edge, but Isis's cunt gripped him so tightly that it wasn't until a few moments later that his pent-up cock was allowed to erupt jizz into the Warmaster's womb! Baren juddered and jerked as he unleashed her tide into Isis's cunt, flooding her to the brim and beyond. Isis rested her hands on Baren's head, clutching his horns in a tight, rule, grip, huffing and puffing through clenched teeth a they ground and gyrated against each other in orgasms, pushing their pleasure past the limit, making it last as long as possible…They groaned and crooned, their lips inches apart, glowering hatefully into one another's eyes as they spurted and clenched and…slowly…settled down.

At last, Isis sat speared in Baren's lap, cum seeping from her cunt. She rubbed one hand lavishly over her womb, grinning stupidly to herself, overwhelmed by the experience of sex for the first time. She shot down a smug smirk, and gave her hips another roll, massaging Baren's massive spent cock inside of her.

"Do you understand, now?" Isis asked in a low growl. "Your true place is here, beneath me."

Baren spent a few more moments breathing heavily, as his cock squirmed and pulsed amid Isis's folds. Then he opened his mouth and said, "No."

Baren finally acted on that desire of his; he grabbed Isis tight and wrested her sideways, into a roll that ended with Baren on top and Isis pressed below, legs spread wide, her cunt still wrapped vice-tight around Baren's daemoncock! Baren gave a few slow, testing thrusts into the squirming Warmaster, then grinned and licked his lips.

"Let's get back to it, shall we?" he asked, then launched himself into a series of slamming thrusts that made the entire bed rock, creak, and groan! Isis herself squealed as she was torn into a world of pure pleasure, the kind of pleasure only Baren could possibly deliver! Isis's huge tits wobbled and smacked together as she was rammed hard, her body shaking and writhing under the daemon's onslaught!

Isis wasn't the Warmaster for no reason, though; even amidst the intense fuck, she managed to met Baren's gaze and shift and squirm her hips in response, meeting Baren's machine-hard thrusts with swift bucks of he own. Baren was amused by the steely look in her eyes, as if she could truly match up to a Daemon Prince! Unfortunately for Isis, she was lacking a vital piece of knowledge:

Baren hadn't even begun to show off his true power.

"Confident, are you?" Baren purred as he slammed that little pussy into a happy stupor. He kept up the pace as Isis clenched her teeth and snarled out a challenging note. "Oh, you are! Well, then - I guess I'm free to let loose then."

Isis really was doing her best, lifting her hips up high as she could and grasping at Baren's hips, urging the Daemon Prince to hammer her with all his might – which Isis believed he was already doing. "Hah! Ah! Hah! Let loose--!" she said. That was a mistake. Her voice turned to panicked squeaks as Baren heaved, and started to pummel that cunt with his godly power raging, ramming his giant cock into Isis's pussy with dense hammer-blows that made her muscles clench and stole her breath away!

Isis could only moan and groan as Baren squeezed and tugged on her wrists, pinning her tits between her biceps and pulling Isis towards him. Harder and faster with each passing second, Baren demolished Isis's pussy, making her cry out louder and more blissfully with each and every dive of the Prince of Slaanesh's hips! Isis's mouth hung open, her tongue drooping outside of it and swirling weakly as she took the slamfuck of a lifetime, her pussy sucking Baren's dick as best it could while she was being so mercilessly pulverized, laid flat and clobbered by the biggest cock she'd ever known! "Guh, guh, guh, hnngh--!" Isis's tongue flopped around in the open air as Baren's daemoncock slammed her without mercy, beating her down into the bedsheets, playing her like some kind of slutty instrument; sure enough, whenever Baren's hips came smashing down, a singsong note of pleasure burst from Isis's mouth. She just couldn't control herself, couldn't stop the music from bursting forth again and again, while her hair shimmered out on the sheets around her, her topknot coming undone, and Baren grinned over her like some kind of savage monster!

"Enjoying yourself?" Baren asked sweetly as he bucked away like the world's most forceful fucking-machine. "Because, believe me, I'm just getting started!"

 He was true to his word. Isis whimpered and sobbed as that monstrous cock ravaged the back of her womb with resounding beats, shaking her back and forth on the bed, making her eyes roll back for long seconds at a time, ahegao-ing in a thoroughly un-Primarch-like manner! "Uogghhh!" she cried, no longer trying to restrain her voice into something resembling speech. Crass, guttural noises flooded out of Isis was she was pounded within an inch of her sanity, ripples dancing across her asscheeks, titties bounding…

She barely managed to gain some control over her voice, rasping out a soft… "Please…please don't…"

Baren smirked down at his prey. "Oh? Don't what, Warmaster?" He sneered as he lowered his head, taking one of her massive tits in his mouth.

The Warmaster sobbed, arching her back, offering up her busty body to the Daemon. "Please…please…you're going to ruin me!" Her voice broke, crying out as razor sharp teeth were dragged over her bouncing rack. "Aren't you!?"

"Is that what you want?" he snarled viciously.

"You…you fucked my sisters!!" Isis wailed, writhing uncontrollably. "You fucked them! You fucking ruined them!"

"Because they wanted it," Baren sneered. "They loved it…" The Daemon's forked tongue lavished Isis's huge tits, running up and down and all over her glossy, quaking flesh.

"Don't ruin me!! Baren, please!" Isis cried, squeezing her pussy for him. "Don't make me!"

"I make the rules, Isis," he spat cruelly. "Not you…"

"I can't…Not like this…I'm not…"

"I'm in control," he said. "I make the rules…"

Isis was helpless, as helpless as any mortal speared on Baren's cock. Blind and near-deaf with pleasure, wailing open-mouthed, curling her toes in the air as she went from eyes-tilted-back, to cross-eyed, to a distant, teary blur that wavered with each thrust! "Hunn--! Haahnn!" Her whimpering cries sounded more girly by the second, when she didn't sound like some kind of animal, and Baren's grin spread ever wider.

"Who makes the rules?" he asked softly. "Do you make the rules?" He smacked both palms down on the sides of Isis's asscheeks – before twisting the Warmaster onto her side and fucking her with a leg slung up and over his right shoulder. Harsh, devastating thrusts rocked Isis's body, rutting her with savage animosity, punished her for her earlier defiance. "Hah! Is this all you were capable of, Isis – moaning like a whore while I stretch out your pretty cunt? Even I expected better."

"So if you don't make the rules," he said as Isis was wailing her head off. "Then who does?"

"Please…OHTERRA!...Baren…please…not-not that!"

"Does your mother make the rules?"

The idea that the Empress could stop any of this from happening seemed almost blasphemous to Isis. She'd been so utterly outmaneuvered without even realizing it! How on Terra was her mother supposed to keep a man like Baren from doing whatever he wanted with her daughters when she didn't even know?

"Fuck…Ohhhhh…Fuck…Oh Terra No!" Isis screamed. "Fucking Never-"

"Who…Makes…The…Rules?" Baren demanded, driving himself into Isis with savage, violent strokes.

"YOU!!" Isis screamed. She squeaked, twisted, and arched in bliss, her howls sounding out tirelessly as Baren bottomed out in her cunt and unleashed a dense tide of daemon cum straight into her womb! Her pussy started spasming, her body shuddering as orgasm engulfed her. "Yesss!! Yessssssss!!" She cried, thrashing wildly, digging her nails into his back, her entire body utterly beyond her control "OHTERRA…Yes!!"

Still with that same embarrassing ahegao expression on her face, Isis's body tensed as she let out a wordless scream, her face turning an ugly shade of red, sweat trickling down her curvaceous, athletic body. She was being turned into nothing but this man's comfort woman, and she'd never felt anything so amazing in her entire life.

"You're...ruining meee!" Isis managed to choke out, even as her pussy clamped down tight around Baren's's cock. At this point, it was like her womb itself was practically sucking on his cock, wrapped so tight around his thick, impossibly hard shaft that Isis's body was little more than a living condom for Baren to fuck into.

Her belly was left swollen as Baren dragged his daemoncock out of her tight-gripping cunt, inch by inch, leaving a thick glaze of slime over Isis's trembling thigh. Freed from the intense pressure of Isis's cum-stuffed womb, Baren spurted a few last ropes across his lover's belly, groaning as he ran his hands up and down his still-erect cock.

"You wanna…haah…you wanna taste it…?"

 Without waiting for permission, Baren grasped Isis's hair and tugged at her, turning her around on the bed and dragging her to its edge, so her head hung over the edge and her hair dangled down to the floor. As Isis wheezed for precious breath, cum bubbling and bursting from her cunt, she opened her mouth wide and showed Baren her slick pink tongue, draped out on her chin like an inviting red carpet. Baren felt a stirring, his massive cock throbbing to life as she gazed into Isis's open mouth.

He growled as his cockhead sank into the warmth of Isis's mouth, swaddled in a heat that made him tremble and bite his bottom lip. "Huuuhn…" Shaking, gripping Isis's shoulders, he guided his cock forwards and inwards. Isis squirmed, gripping the bedsheets tight, tearing the fabric with her fingernails as she swallowed her way down Baren's mighty rod – polishing the slime off its obscene shaft and replacing it with a thick glaze of saliva. Gaghk…Gaghk… Isis's muted noises were nothing compared to her wild moans and groans before, but they were no less gorgeous for it, like music to Baren's ears.

Baren drew his hips slowly back, until just his cockhead rested in Isis's mouth. He gave a chuff of happy pleasure when he felt Isis's tongue sweep around his cockhead, playing with it, inviting it back inside – an invitation he'd be remiss not to accept. Baren bucked his hips and drove his daemoncock down Isis's throat, ramming it home with a splatter of spittle. Isis jolted, tits bobbing slightly from the impact, squeezing her fists around handfuls of bedsheet – but Baren was already pulling back for the next thrust.

 He rocked the bed with her awesome pumps, fucking Isis's throat slowly at first, but picking up speed as the Warmaster adjusted to the sensation of his tremendous cock plunging the depths of her throat. Her tits beat together deliciously, for Baren's viewing pleasure, as he lurched his hip. He clutched Isis's tits by their soft, squishy flanks and bunching them inwards while he hammered harder, faster, harder! Gaghk! Gaghk Gaghk! Spit flew from Isis's lips as they were repeatedly squished under Baren's charging hips, her eyes rolling back and watering heavily as she took more dick down her throat. Her tits leapt in Baren's grip, which tightened as the Daemon grew hotter and hornier. Baren was losing his mind with pleasure now, thrusting without thinking as he fucked Isis silly.

Baren baked his cock in Isis's throat at full-speed, plunging and retracting is entire rod several times per second, groaning at the thrills of bliss that went through him. He didn't care if Isis desired breath or now; all he wanted was to keep plunging his cock in and out of that tight little fuckhole for as long as she could possibly endure it…which, based on the noises Baren was making, wouldn't be long. He barked out thick cries of bliss, canting his head and rolling her shoulders, gripping Isis's tits so tight that his handprints would paint them for days to come. Baren kept on pumping, kept thrashing his cock into Isis's throat. He shot his hips forwards, groaned, and erupted a monstrous load into Isis's stomach – flooding it with unruly jets of semen. 

Baren stepped back and admired his work. Isis Lupercal, the Empress of Mankind's most beloved daughter was now nothing more than another one of his fucked silly whores. Covered in semen and blissed out of her mind. The symbol of Slaanesh appeared on Isis's heavy tit, and the Eye of Terra appeared on Baren's palm. The Daemon grinned, clenching his fist and blinding the Empress's eyes as he stood triumphant over her Warmaster.

"Uh…" came a voice by Baren's feet. He looked down, and blinked when she saw Aurora peering up at him.

"Oh, it's you," he said. "What do you want?"

 "I was…wondering if…we could keep going…?" Aurora asked.

 Baren rolled his eyes…then sighed, squared his shoulders, and reached down. He grabbed Aurora by her white locks and tossed her unceremoniously onto of her moaning, panting sister– and socketing his cock into Aurora's tight pussy, started to thrust – earning him a depraved squeal of delight.

 "One round," he said.
