"As for you… you'll do whatever you want with the ability. It's yours, after all."

Thaddeus' words ring through Sage's head, even as she sinks to her knees in front of him wearing nothing but her undergarments. He looks a little surprised at this, but the way his mutation works, any method of taking his seed within her body should provide a boost to both of them. Including imbibing it.

Taking hold of his dick with one hand and reaching up to fondle his balls with the other, Sage doesn't hesitate to plant her lips on the head of his cock, sucking it into her mouth and beginning to bob up and down his length.

She might have a brain capable of processing things at astonishing speeds on the same level as a supercomputer, but that didn't mean she couldn't improve said computing even more with mundane techniques.

One of the ways she'd found that helped her think even more clearly than her usual supernatural thinking was to have something in her hands. Something to occupy herself with physically. It was a natural extension of her ability to multitask on a level no other human being could.

As such, it was actually better for her to suck Thaddeus' cock and fondle his balls rather than just lie back and let him fuck her because it meant she could really focus on her thoughts… and feelings.

It had only been a few days since Thaddeus killed Sebastian Shaw and turned her entire life upside down. Six, to be exact, seeing as it was Thursday right now. Tomorrow night would make it a full week. For someone like her, processing the events of the past several days should have been relatively easy, to be fair.

Indeed, over the weekend she'd very much felt like she was already getting used to her new routine. She was Thaddeus' personal assistant now, Xavier's spy on him and Emma's activities, and ultimately a double agent for both Thaddeus and Emma against Xavier.

Convoluted? Maybe. Complicated? Definitely. But nothing someone like her would struggle to handle. Right?

But then Thaddeus just had to go and say things like what he'd said so nonchalantly a few minutes ago. Flicking her eyes up to his face, Sage lets out a muffled reverberating moan as she descends further down his cock… one that Thaddeus matches with a groan of his own.

Was she upset that he'd kept information about her own powers from her? Perhaps a little bit. But at the same time, she understood why he hadn't said anything. If she wasn't who she was, Sage is sure she would still be coming to terms with the revelation. It was one thing to be able to perceive DNA. She was well aware how much of a special kind of bullshit that already was.

But to be able to draw the potential out of others… it was close to what Thaddeus' own mutation allowed him to do, except from the sound of things she would be able to do it without having to get down and dirty with every single person she chose to help.

… Was that what she intended to do with such power? Help others? It sounded nice on the face of it, but Sage really couldn't say for sure. And that was the main problem she was struggling with right now, wasn't it?

"Mmm~"

"Fuck, I'm getting close…"

Sage had spent much of her life as a pawn. Sebastian Shaw's death hadn't changed that, it had merely changed who exactly held control over her movement on the board. And not even that much. She was still partially Xavier's creature, after all.

But Thaddeus, who had more right than most people to order her around and command her… wasn't going to restrict her use of this new power he intended on drawing out of her. He wasn't going to tell her she wasn't allowed to use it, even though that was technically something he probably should have done. He hadn't told her that she could only do what he said she could with it.

Instead… instead he'd said she could do whatever she wanted with the ability. Because it was hers. Because… in Thaddeus Cumming's eyes, Sage wasn't a pawn. She was her own person.

For the living supercomputer, Thaddeus' words have come the closest to bluescreening her that anything has in a very long time. They still don't quite manage it, of course. She is the perfect multitasker after all, with the ability to partition her thoughts into multiple separate boxes.

As such, when Thaddeus cums in her mouth a moment later, it's not affected by Sage's internal fretting over how she's supposed to feel about his words. Nor does she 'mindlessly' swallow his seed down either. She's attentive and focused on his pleasure, still fondling his balls even as they unload right down her gullet.

She guzzles his cum while staring up at him all the while, focused on the little things like the minute twitches Thaddeus' facial expression makes as he cums. He's… handsome, she finds herself noting. That was something Sage had already known, of course.

Objectively, Thaddeus couldn't be anything BUT a Modern Day Adonis thanks to his mutation. Other men might hate it, but he was what peak performance truly looked like. However, that had been an unbiased and honestly completely emotionless observation for Sage before. Now though? Now she was feeling something strange. Something she couldn't quite quantify.

As she swallows his seed and both of them feel the boost, Sage shivers and pulls off of Thaddeus' cock with a pop. Then, she rises gracefully to her feet and reaches behind her, deftly undoing her bra and letting it fall away from her breasts.

Thaddeus, ever the lustful gentleman, watches her with hungry eyes even as Sage lets him soak in the view of her bouncing tits for a moment before turning on a dime. Hooking her thumbs into the waistband of her panties, she bends over as she slowly but surely draws the underwear down her long, shapely legs.

Finally kicking them off, she then immediately climbs up onto the bed and plants herself there on the edge on her hands and knees, with her legs spread nice and wide and her pussy exposed in offering.

Thaddeus doesn't waste time. He grabs hold of her hips and enters her from behind, standing there at the foot of the bed and sliding his spit-polished cock right into her moist, wet cunt. Sage gasps, her breath hitching, and proceeds to knead the bedcovers beneath her, her hands all but clawing at them continuously. It helps her continue her internal deliberations.

Did she… was she developing feelings for her newest master? Because at the end of the day, that was what Thaddeus was. He was her superior but it wasn't quite accurate to call him her boss or employer. No more accurate than it had been to call Shaw such things.

No, their relationship went a touch deeper than that. She was supposed to be just a tool after all. Anything else got in the way of the Mission.

Sage arches her back as Thaddeus pounds into her cunt. She could have refused to let her body react to the experience, but she refrains, instead allowing herself to 'succumb' to the pleasure. Again, with her mind partitioned half a dozen times, the difference between her outward and inward selves could not be further.

That doesn't mean she fakes it. It's the exact opposite in fact. Thaddeus gets the real thing, with all of the moans and shudders and pleasured cries as he fucks her like a bitch in heat right there on the bed's edge.

At the same time though, Sage finds herself… introspective. What was the Mission, anyways? Xavier had wanted her in the Hellfire Club to be able to provide him with information. She wasn't sure he would have ever had her help take them down from the inside truth be told. His end goal definitely hadn't been to destroy Sebastian Shaw, or he would have put more effort into pulling her out after the mutant's death.

Sage realizes now, as this energetic young man fucks her through orgasm after wanton orgasm, that she doesn't understand precisely what Xavier's Mission really is. And more than that… she's not sure his mission is necessarily HER mission.

She's just a pawn. She's not supposed to make choices. And yet… and yet, Thaddeus didn't agree, did he? Whatever she wanted. That's what he said. Because it was hers. That's what he'd stated.

A shudder runs through Sage's body that isn't entirely connected to the physical pleasure Thaddeus is visiting upon her. Until finally, she feels him cum inside of her, filling her with his seed. Another boost. More power… for both of them.

Because that was the great equalizer of Thaddeus Cumming's mutation, wasn't it? He could not take without giving back. Or least not with his base power. Any woman he had sex with who had abilities of her own… he would gain access to those. But at the same time, any woman with abilities of her own would find them similarly enhanced.

It was a win-win situation, albeit with Thaddeus' half of the win lopsided ever so slightly in his favor. But then… he deserved something for being the one to provide the experience in the first place.

As he pulls out of her again, Sage rolls over onto her back without a word, pulling her legs up with a hand under each knee and spreading them nice and wide for him in offering. The young man is inside of her once more a moment later, leaning forward to plant his hands on either side of her head as he fucks her soundly there on the bed.

The lopsided nature of Thaddeus' power came from the fact that he could fuck any woman and get a boost. He didn't have to keep fucking someone forever if he didn't want to. He could stop at any time… and move on to someone else.

There were classifications for mutants when it came to levels of power. The greatest among them were considered 'Omega Level'. An 'Omega Level' or 'Omega-class' mutant was a mutant who's power had no definable upper limit. They were rare, thankfully… but Thaddeus had to be one, that much Sage was certain of.

His powers would only keep growing from the look of things. So long as he was having sex with someone, he was always getting stronger. No matter how many times he slept with one woman, he would always eclipse them on account of all the other women he slept with in between.

Perhaps that was why he wasn't worried about her. As Sage's breasts bounce up and down, her face bright red and her breaths coming out in panting, gasping moans, she recognizes that it doesn't matter what sort of power he gives her… he'll always have more. Indeed, in terms of telepathy, he just had to make sure he fucked Emma as much as he fucked her and the White Queen would always be the much stronger psychic.

In that way, maybe it made sense that Thaddeus wasn't worried about giving her access to more power. But if that was his thinking… it was still rather short-sighted of him. And frankly, far too generous. By all rights, she should have just taken his overly permissive words and ran with them.

… So then why was she hesitating to do so? Why did she find herself so damn conflicted?

As Thaddeus spears into her cunt over and over again, Sage lets go of her legs and reaches up to grab hold of his face, forcing him to look her in the eye. She goes from flustered, panting, and moaning to serious in the blink of an eye as one partition of her mind asserts itself over the previous. Like different parts of her switching places in the driver's seat.

"Thaddeus."

Raising an eyebrow at the chance, the handsome young man hums.

"Yes?"

"You know you shouldn't be giving me carte blanche with such an ability, yes? Writing me or anyone else under your control a blank check like that is just asking for trouble."

Thaddeus pauses before snorting derisively as he continues jackhammering away at her cunt. The feeling is incredible of course, and she certainly enjoys it… but she's focused on the conversation right now, even as her nipples are hard as pebbles and her pussy clenches around his cock in an explosive climax that ripples through her but doesn't really touch her expression.

"Maybe. But the way I see it, I'm not writing you a blank check, Sage. I'm simply reaffirming your right to your own autonomy. Sure, you might be working for me and Emma now… but you aren't our slave."

Sage scoffs.

"No. I'm your pawn. And you would do well to remember that, Thaddeus."

Frowning, Thaddeus stares at her intensely for a moment in a way that would have probably made her squirm if she was anyone else.

"… Maybe I don't want a pawn. Maybe I want something more."

Sage's breath hitches as his words hit her far harder than should be possible. She tries to maintain her composure, something that should have been easy for her… and yet… and yet her voice wavers and trembles all the same.

"What… what more can someone like me be than a pawn, Thaddeus? It's all I've ever known."

Determination spreads across Thaddeus' features and she can tell immediately that he's going to say something dumb.

"I don't know."

She jerks at the blunt admission of ignorance. Then she blinks at his next words.

"But I'd love to find out with you… if you'll let me."

Sage stares up at the impossible young man for a long moment, completely at a loss for words. That… didn't happen very often. She was a woman of few words usually, but she was never truly at a loss for words. Of course, he'd also been the cause for her last true loss for words… six days ago when he'd killed Sebastian Shaw and upended everything.

A shiver runs down her spine and Sage suddenly finds herself kissing Thaddeus, having pulled his head down to hers as she leaned up so that she could smash their lips together.

They don't talk very much for the rest of the night, mostly because they're too busy getting things done so that Thaddeus will be ready for tomorrow morning. And Sage… Sage doesn't know what she'll do next with the abilities they're planning to unlock tonight. But apparently it's her choice, so she'd better start figuring it out.
