Yes, And He Doesn't Stop There

As explained before, Rob's magical pregnancy power (he really needed a better name for that) sort of existed along the edge of his consciousness, always there buzzing along the periphery, but never active until he needed. Whenever he did cum inside one of his girls' pussies, his hot, virile seed surging into the deepest recesses of their wombs, that buzzing at his periphery would would come to the forefront, a mental drop-down menu like in a video game.

Do you want to knock this bitch up? Y/N?

And, with Rob looming over Cersei in a full-on mating press, balls deep in her queenly cunt, having struggled all day to fight this primal instinct of his, and with only a shred of conscious thought holding him all together, really only had one response to the menu.

Y

Y

Y

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Fucking Y as hard as physically possible, fucking finally get this arrogant fucking cunt fucking pregnant!!!

Rob reached his climax, his destiny now set, and his rod roared like a raging storm, unleashing it's payload in a seemingly unending tide of semen, flooding Cersei full. Every last nanometer was painted with thick, white seed, quickly backflowing and sputtering out from the barest of spaces between her snatch and Rob's dick. Rob could see from his mounted position Cersei's mouth wide open, her tongue flapping loosely, and the chords in her neck undulating wildly. She was screaming in pleasure. Rob could not hear her over the pounding of his heart, swimming in ears; the roaring of his blood, surging through his body.

That pure, primal, primitive, sensation of claiming a mate and planting your seed in her, showing the world that woman was yours and ensuring the survival of your race.

But Rob did not stop with just one mighty blast of cum. He squatted atop Cersei's prone form, legs fully pushed back, dumping more and more of his rich, thick seed into her. Her pussy made wet gurgling noises, from Rob's cock messily sliding in and out amidst the pool of his cum, to the bubbling, frothing overflow as cum exploded out from her brimming pussy.

With a deep, satisfying rumbling noise, Rob finally pulled out, Cersei immediately gasping in shock. She convulsed on the floor, swimming in a growing pool of seed as her vaginal walls contracted wildly, expelling more and more of the thick, white slime. To Rob's surprise, amusement, and delight, Cersei was branded with a cervical tattoo of a cattle skull - his signature mark as an artist - etched on her flesh in bright, glowing purple-pink light.

"Neat..." Rob said to himself, before he turned his attention to his next target. His next victim.

His next mate.

Because he was far from done today...

With the celerity of pure purpose, Rob moved like a shadow against the wall, loping across the foyer with impossible speed and appearing by Liara's side. One large hand rest upon her head, fitting the cartilaginous ridges in between his fingers. With her heels, Liara almost stood as tall as Rob yet, somehow, he seemed to loom over her in this moment, a great and oppressive power whose shadow she could not escape.

"Oh, Liara..." Rob gave out a leonine purr, causing both Liara and Sombra to shiver. The two had watch the entirety of Rob breeding Cersei, Sombra shocked and frightened by the suddenness and brutality of it all, whereas Liara was simply fascinated by the end result, and jealous of the act itself. Now, though, both went stiff with apprehension, prey paralyzed before a predator.

"Sir..." Liara said in a small, shaky voice, despite her best efforts. Her eyes were unable to leave Rob's still erect cock, idly twitching every so often, spurts of cum still expelling from it with every spasming motion.

"Hnng..." Rob drank in Liara's magnificent blue form. "Do you remember what you said to me that night when you came to me, presented your blue-tiful new body to me, and pledged your brilliant mind to me?"

"Yes, my lord, I-"

"You said to me... hmm, what was it? Oh, yeah... 'Breed me over and over until I give you a legion of daughters worthy of a man like you'." Rob grinned viciously, especially at Liara's dark blush and a lustful glint in her eyes. "That you wanted more than anything to be my 'busty, big-bellied blue broodmare'. Is that right? Is that what you still want, Liara?"

Several emotions flickered across Liara's face in short order - from trepidation to dismay to sheer curiosity - but it eventually settled into a wanton smile. "It is my dream, my Master. It's what I want most in this life, is to bear your progeny."

Nodding, a very pleased noise rumbled in Rob's chest... before her unceremoniously threw Liara to the ground, the Asari yelping in surprise. Once more, moving with shocking swiftness, Rob was on top of Liara before she had any chance to gather her wherewithal, taking her from behind and slamming into her without any grace or etiquette, again submitting to primal instincts and ravaging his soon-to-be blue broodmare.

And Liara loved it.

She loved being taken like an animal. She loved being used like an object. She loved being chosen by her Master to carry his child. She threw her entire being into this brutal mating ritual with gusto, throwing her head back and yowling loud enough to shake the rafters, as Rob mindlessly pumped away.

"UNG! YES YES YES!!! More, sir, more! Fill me up with your potent seed! By the Goddesses, I never expected this to happy so soon, but I'm so happy. So happy. Soooooo HAPPY MASTER!!"

"You slut you bitch you whore! All Asari are just walking baby factories looking for a stud to knock them up and make more whorish, fertile daughters! A race of perverts and sluts and I fucking love it!! I love you Liara!!!"

Already put out by the suddenness of Rob's mood change, Sombra watched her new Master succumb to new depths of madness in his urge to breed Liara, colour fading from her face and eyes bulging outward. She did not deny Rob his right to use his slaves like this, but still, she wasn't wholly comfortable by how he was consumed by his breeding fetish.

Then, Sombra realized, the two of them would be done sooner than later. And she was also a fertile, submissive woman nearby this monster of a Master. Sombra always believed discretion was the better part of valour, and those words never held so much weight as right now.

"So, um... I don't think I'm ready for a child, so I think I'll just leave you two to this..." Sombra said, loud enough to be heard over the sounds of fucking, but she knew Rob and Liara were to engrossed with each other to really pay attention to her. "I'll be... somewhere. If you don't want me gone, Master, just say so and I will obey." Rob's only response was to grunt and swear and grown, hilting Liara's blue cunt with powerful, energetic thrusts. "'Kay, thanks, you two enjoy yourself, bye...!"

And Sombra moved faster than she ever had in her life, quickly fleeing the scene before she got swept up in the tornado of lust.

In the end, Liara ended up much like Cersei - bred, branded, and brutalized; a sweat- and cum-stained mess on the floor, drooling and smiling in delirious joy, lovingly rubbing a hand over her belly and the cattleskull marking upon it, caressing the seed planted with her, soon to bloom into a beautiful Asari daughter for her Master. Rob rose and surveyed his handiwork, Liara then Cersei - the hyper-bust blonde giggling dumbly while sucking on one of her own nipples - and then growled in frustration when he realized there were no other women for him to breed. No unclaimed wombs to be fertilized by his mighty seed.

Yes, so far gone to his own desire, those were the only thoughts on his mind: find, conquer, fuck, and breed. He needed more, more of his sluts and slaves to open their womanhood to him and accept their ultimate fate. Consequences were the furthest thing from his mind. The lack of infrastructure for this brood of children was the second furthest. Rob took one last look at the two women who had the honour of bearing him his first children, and was about to set off to find another hole to fill.

That's when Shulkie came waltzing in, oblivious and bubbly, on mincing, bimboish steps.

"Robbie, baby~ Like, do you wanna help me pack before I move in with Missy Sami?" The great big green bimbo tittered. In her defence, brainless or not, it was not unusual to come across Rob in the aftermath of wild, unrestrained fucking, with his partners reduced to near-**** on the ground, like so much detritus. But any non-bimbo in the harem could look upon Rob and realized something was wrong. "I totes am having trouble which outfits to pick. You're a super smarty, you can tell Shulkie what she needs."

Rob had largely ignored Shulkie's inane chattering up to a point, but some primitive part of himself then sensed her presence, Rob snapping his head around to stare at the gorgeous green Amazon, and dreaming of how beautiful her daughters would be.

His cock snapped to full height, unconsciously growing in size and thickness to match the proportions of this new partner.

That Shulkie definitely took notice of, pressing a finger to her lips and smiling brightly. "Ooh! Shulkie smash?"

Rob grunted, lumbering forth, the power of purpose fueling his every step. "Rob smash. Rob fuck. Rob knock-up big, green bimbo!"

As I said prior, this arc and the following one will see plenty of status-quo changes and advances to whatever passes for a "plot" for this story. Babies are on the way! The first of many! But just how far does Rob go, lost in the throes of his own monstrous desires?
