50%: Cersei

A good break could make the world of difference. It was a lesson Rob had learned through his career as an author and writer. It wasn't a panacea for everything, but when it worked, Rob felt like a million bucks afterwards.

So, after the pressure of his erotic experiments, Rob had a cold shower, plenty of water, a light snack, and used Urbosa's mouth and throat as a fleshlight, depositing every last bit of cum that should have gone to painting Ahsoka, Barriss, and Talon's insides pure white. Urbosa had done nothing wrong, yet Rob had taken out all of his recent anxiety on her, pinning her down and mercilessly facefucking her with his ever-growing schlong, filling her belly so much she was left a coughing, burping mess when he finally pulled out.

Still, returning at the site of the experiment, Rob felt like a new man, wearing a broad smile and walking with a lightness and energy in his step.

"Ladies," he greeted Sombra and Liara fondly. "Are we ready to continue?"

"We're ready if you are, sir." Liara replied, a small smile coming to her lips, eyes deeply focused on Rob. "It seems like your suggestion for a break was the correct one. I do apologize for how I acted earlier, I was-"

Rob held up a hand for silence. "Liara, please, you have nothing to apologize for. I absolutely have not been one-hundred percent recently. I'm a little untethered without Zatanna's presence, I will admit, and am internally debating a few choices regarding you girls. Your concern was deeply appreciated and totally warranted, so thank you, and I apologize if I upset you with my behaviour."

A blush crept into Liara's cheek, dark purple against her blue skin. "Oh, please, sir. You're the Master, you never have to apologize for what you do. I'm just glad it looks like you're feeling better."

"Ugh, give me a break..." Sombra complained loudly, though with a teasing smile. "I never imagined a harem of sexslaves could but so mushy and touchy-feely." She stuck her tongue out at Rob, chuckling. "The way you act is so unbecoming of your position, so sickeningly sweet, I can feel the cavities forming right now, jefe."

Rob took the barb with good humour, smiling and chuckling back to Sombra. "Well, then, maybe I should have had Liara turn the program up and melt some of those brains of yours." Rob brushed away Sombra's long, swooping bang on the left side of her hair. "To spare me from your wicked tongue."

"Oh, come now, you know you love my tongue, stud..." The two were inches apart, Sombra opening her mouth and waggling her tongue in a tantalizing gesture. "Would you like to see what else it can do?"

Experiment or not, Rob was willing to indulge such heated teasing from his newest pet. Life was only worth it when you could stop and smelled the flowers every once in a while...

"Ahem. Pardon me, my lord, but you did summon me..."

But Rob would have to wait to sniff this particular flower, turning to greet his final test subject.

"Apologies, Cersei, we all know how busy you are around the house." Rob said in a mocking tone, earning a sly smile from the former Queen, as he reached down to kiss her hand.

Clad in sheer lingerie and with her hair tousled in loose ringlets, eyes heavy and half-lidded, it looked as if Cersei had just been roused from bed, save for the large goblet of red wine in her other hand. She had embraced Rob's new role for her with gusto, the former monarch turned lazy, easygoing whore usually spending most of her days sleeping, drinking, eating, and fucking. The most strenuous thing Rob had ever seen her do since her enslavement (besides submitting to his cock) was lounging out by the pool all day. But, of course, Rob couldn't complain about what he had done to her. It was immensely satisfying to see Cersei stripped of all of her pride and ambition and become somethings she would have absolutely loathed.

"And yet, I always come whenever I am asked, my Master." Cersei murmured in a lazy drawl, taking a long sip of wine from her glass. "Like the good whore that I am."

"Yes, you do." Rob stole the goblet from Cersei's grasped, quickly downing the wine with gusto, Cersei looking mildly miffed it had been swiped from her. "And I'm about to make you an even better whore." He gestured to the chair set up before the screen.

With mincing steps, Cersei made her way to her throne, pointedly ignoring Sombra and Liara along the way, not even glancing in their direction. Liara could care less about Cersei's attitude, but Sombra turned her nose up and made a face behind Cersei's back.

"Okay, Blue, let's take this perra down a couple pegs, yeah?" She whispered to her partner in crime, Liara giving Sombra a small smirk in response.

"We'll do this by the book." Liara said, organizing her notes and initializing the program. "However, I am very curious how much someone will be effected by fifty-percent. We have seen increments by ten, and thirty is already quite intense - speaking from personal experience, after all - so fifty could be quite a jump..."

"Master..." Cersei whined, lazing in the chair, looking like she was about to fall asleep. "All of this nonsensical babble is leaving me restless. May we please begin whatever sorcery you have in mind?"

"Oh, you poor dear..." Rob gave another mocking grin to Cersei, standing by her side and running his fingers through her golden blonde curls. "Well, you heard the lady, she's ready and I am most certainly ready. Let's begin." He nodded to Liara. "If you would, dear doctor."

A few more taps of the tablet and Liara nodded along. "But of course. Final experiment for the day, set at fifty-percent intensity. Our subject is Cersei Lannister and we are starting... now!"

For the fourth time today, the Pink Room's bimbofication powers were channeled into the monitor set-up, bathing their victim in lurid pink light. Eyes snapping open, Cersei quickly woke up in the face of the sheer psychic and sexual ****, emerald eyes overwhelmed by spiraling pinkness. Cersei's hands turned to claws, desperately gripping the arms of the chair, even as the rest of her body listed forward, as if drawn by the irresistible gravity of the pink. Her mouth hung open, a perfect, hollow O-shape, as a low, rumbling groan resonated from her throat through the cavernous opening.

Then, quickly, very quickly - quicker than any of the other girls subject to the same treatment today - the physical changes came to Cersei's form. First, with her waist shrinking and her hips expanding. And then her breasts, already large and bountiful, started growing.

And growing

And growing

And growing

And gro - holy fucking shit! Rob began to panic, because just how big were they going to grow?

Now, ever since wishing upon the lamp and beginning his new life, Rob had become something of expert of female breasts. He had seen a lot, felt a lot, tasted a lot, and played with a lot. Boobs of all shapes and sizes! And, as such, he was no stranger to jumbo jublies or titanic tits. Gun to his head, he would say the bustiest women in his harm would be Liara, followed by the new Talon, and then Tifa, Nami, and Samus loosely filling out the rest of the top five. And all five of those women had huge breasts, Rob could not emphasize that enough. Gigantic, gravity defying, all natural, bigger than a watermelon on steroids tits!

Cersei's new rack dwarfed all of them - full stop, no contest! They were probably larger than two or three of his top five put together! Cersei now had two overinflated beachballs hanging from her chest. And if it looked like her body was being pulled along by gravity beforehand, now the weight of her mammaries were threatening to pull her down to the ground and keep her there.

Yet, despite all that, Cersei managed to stand up onto her feet with light, delicate steps, as if her new heaving hooters weighed nothing at all. Eyes still consumed by pink, Cersei smiled brainlessly into the screen, massaging her breasts with fervent desire, fingers all but vanishing into the plump, thick flesh of those two humungous orbs. Rob's eyes went in circles, as he closely watched them go up and down, round and around and around, over and over, Cersei babbling along to the enticing rhythm of her dancing tits.

"Fuck me... big tits for a big whore... yes... perfect...love my huge fucking tits... big tits...need big cock... big cock for big whore... cum and cock... want it... babies... breed me... cock and cum and babies... knocked-up slut... all I'm good for... all I want...I want cock... mmm....cooooookkkkk..."

"Liara...please turn off the program..." Rob said, very softly, voice distant. He was absolutely mesmerized by Cersei's transformation and by her new mantra. "I think we've seen enough..."

Liara quickly complied, shutting the screen off and, just as fast, flipping a switch in Cersei's head. Her trance broken, Cersei's eyes returned to normal, her dazed smile retreated, and she fell to her knees. Not due to the weight hanging from her chest, but due to overwhelming physical needs. Her hands dropped from her breasts to her pussy, savagely fingering herself while she moaned in desperation.

Rob's cock was out, fully erect, and now he too felt himself drawn forth by an irresistible gravity...

Cersei turned to the approaching Rob with a smile, one so pleading and **** and needy it looked plain wrong of the visage of Cersei Lannister. Or it would have, if Rob hadn't completely destroyed who Cersei was.

"Master! Master!" Cersei spoke in breathy tones, fingers never leaving her slit. "Please, take me and fuck me! Use me! I want that big, hard cock - no! I need it! I need it in me! It's all I'm good for, all I was ever good for, even before you claimed me for your own! I'm just a big slutty whore, meant to please men! Would fucking my pussy please you? Cumming deep inside me womb? Impregnating me with your child? You can do that to me. You can do anything to me, just please, give me your cock!"

Rob's brain had turned off. No matter what preparations he had made prior to this, his will would have crumbled and been overtaken by a primal, ancient part of his mind. Being taunted by Ahsoka and Talon and their new luscious bodies was bad enough, but Cersei out and out begging for his cock to knock her fat cunt up? He wasn't made of stone. He felt his blood rise, felt a beast deep within him stir and roar and roam and hunt and revel in it all!

Men and women were made for one thing, after all...

Cersei was blissfully unaware of the change in Rob's mental state, dumbly chanting, "Cock, cock, cock, cock," over and over again. That is, until Rob threw her to the ground and pinned her down, throwing her legs up so that her knees were around her ears and entered her wondrously inviting pussy.

Cersei squealed in delight, as all of Rob's weight was brought down on her and his cock plunged in and out, again and again. There was nothing romantic or skilled about any of this. This was primal, bestial, wild fucking, heated and intense. Pleasurable in a way, but more focused solely on making babies. And that was where Rob's mind was, not on his pleasure, definitely not on his partner's pleasure, but on dumping his seed into her womb and making a baby.

It was what Cersei wanted. It was what he wanted! But, seconds away from his climax, a flicker of consciousness returned to Rob...

Around 50 chapters or so ago (oh wow, we're nearing up on 100 chapters!), VoidGolem suggested Cersei transforming into something along the above lines - a man-pleasing, cock-hungry, pseudo-bimbo - attaching the image featured in this chapters along with it. Well, sorry for taking so long on using this suggestion, Void Golem, but it was perfect and irresistible for this moment and this story beat.

Also, there is something truly delicious about such a fate being inflicted onto Cersei Lannister. A woman whose personal conflict involves her slowly realizing that her ambition, status, and wealth mean nothing against the strict gender norms of her society, an turning that woman (who, among others, is vicious and vile and wicked as they come) into a submissive whore with an impossible body is just perfect.

Now, we're onto the climax (pun intended) of this arc and Rob is about to cross a very specific Rubicon.
