Mercy Graves has a decision to make. But truthfully, she's already made it.

-x-X-x-

Mercy Graves was a lot of things to Lex Luthor over the years. His bodyguard, his secretary, his fixer… even his chauffeur. It's strange then to find herself in the back of a limousine for once. She's much more used to being the driver than just another passenger. And yet, she's used to a lot of things that are no longer true.

Lex is gone. Seeing Brainiac's final confrontation with the Justice League had hammered that point home for Mercy all too quickly. As much as she hated to admit it, Superman was right when he said that the real Lex Luthor would never casually talk about wiping out the entire human race.

For all his obsession with Kryptonians, for all his ego, Lex had forever believed that human beings would ultimately rise to the top and seize their destiny as the apex sapients of the universe. And he would of course be their leader.

That… thing that wore Lex's face and claimed to have usurped control of Brainiac was nothing but a lie. Either it was Brainiac just putting on a façade and wearing a skin-deep version of Lex Luthor's personality, or it was some amalgamation of the two beings that was nothing like the man that she'd faithfully served all these years.

In the end though, it didn't matter which it was. It didn't even matter if Lex Luthor could have still been saved. The mothership had self-destructed and while Brainiac might one day be back the real Lex Luthor, HER Lex… was gone for good.

Accepting that was difficult for Mercy. Accepting that Lex's clone wasn't truly to blame had been even harder though. Still, when faced with a choice between siding with the Justice League and keeping her mouth shut, Mercy had ultimately done what she knew the original Lex would have wanted her to do. Even after everything, even after this 'Alex' usurped his life, if Lex had been there… he would have stuck it to Superman and all of those self-righteous do-gooders in tights just as his clone did.

For that, Mercy had decided she was willing to live and let live as far as Alexander Luthor was concerned. At the same time though, the clone had been right… they couldn't just pick up where they left off. She couldn't just slot back in as this new Lex Luthor's right-hand woman and be happy with that.

That led to where she was now, in the back of a limousine, sitting across from one Lucien Luthor, the bastard son of her former boss. His own 'right-hand woman' Blackfire is sat to the side, her arms crossed over her chest as she watches Mercy with a flattering amount of wariness. As tough as Mercy is, she's not 'alien' tough. The exiled Tamaranean Princess could take her down relatively easily if she wanted to… and so could Lucien himself if Mercy wasn't mistaken.

Indeed, as good as he is at hiding it… Mercy has been assessing dangers and assigning threat ratings for too damn long not to be able to see the obvious. It's been a while since she and Lucien last saw each other on his birthday… a while since she perhaps made the somewhat foolish move of cutting him off because she'd caught him lying to her.

… If she hadn't done that, if they'd worked together more, was it possible they could have figured out Brainiac took Lex earlier and potentially rescued him? Mercy knew that particular idea would be keeping her up at night for quite some time into the future, more than likely.

Still, all in all… Lucien has grown a lot since his birthday. He's become more than he was before… he's become a proper metahuman.

Compared to Lucien and Blackfire, Mercy is no threat. So yes, it is a point of pride that Blackfire is treating her with a certain degree of wariness all the same. Even if it's a small consolation to everything else.

"Have you given more thought to the idea of coming and working for me, Mercy?"

Lucien's words don't necessarily pull her out of her thoughts, since she wasn't that deep in them in the first place. And yes, she has been thinking about that. She's been thinking about it a lot.

"… I believe it's the best path forward for me, yes."

Lex's son looks surprised by that, his brow raising at her words.

"Huh. I'll admit, I wasn't expecting you to agree so easily."

Smirking, Mercy shakes her head.

"Don't misunderstand me. I want something from you, Lucien. And I'm willing to do an awful lot to get it."

Her jacket is already off and folded on the seat beside her. Reaching up, Mercy begins to unbutton her blouse right there in the back of the moving limo. Blackfire's eyes widen while Lucien goes still as she removes her top.

"Oh?"

She'd been his first. You never forgot your first and Mercy can tell that holds true for Lucien as well. Taking the young man's virginity all that time ago might just pay dividends now, she supposed. Stripping off her bra next, the blonde frees her breasts from their confines, enjoying the way Lucien lets his eyes glide down to them.

"Yes. I am."

Sliding down out of her seat, Mercy kneels on the limousine floor and shuffles forward until she reaches Lucien. She has to pass Blackfire to get to him, but the alien woman doesn't stop her. Frankly, she should have erred on the side of caution and prevented Mercy from getting closer. But that was something to be brought up later.

For now, Mercy grabs Lucien by his knees and spreads his legs apart so she can slip into place right between them. He looks down at her wordlessly, even as Mercy moves to extract his cock from its confines. Only then, before she can wrap her fingers around his throbbing dick, does Lucien finally stop her.

"What exactly do you want from me, Mercy?"

Mercy licks her lips at that. For just a moment, she heard Lex's voice and saw Lex's face looking down at her. It's enough to make her mouth go dry for a moment before she finds her voice again.

"Power, Lucien. I want revenge on Brainiac. Whenever he shows up again, whenever he comes back… I want to destroy him. But I'm not strong enough. Neither are you."

Out of the corner of her eye, Blackfire shifts at that, clearly irritated by Mercy's blunt observation. However, Lucien just smiles and bobs his head in agreement, accepting that she's right. There was a reason Lucien had stayed down beneath LexCorp Tower with the clone and it wasn't just to keep an eye on 'Alex'.

"But you can make us stronger, can't you?"

Lucien pauses at that and Mercy grins up at him crookedly. This time when she goes for his cock, he doesn't stop her. Soon enough, his member is out in the open with her hands stroking it up and down slowly and sensually.

"When did you realize?"

Mercy shrugs in an exaggerated motion, well aware of what the motion will do to her breasts.

"Realize? I wouldn't put it at just that. I know you could do more than just 'look' as you originally told me so long ago, because you needed to confess as much to get me to help you with the clinic in Gotham. From there though… it was increasingly obvious that you can do more than just heal, Lucien. You're beyond peak human at this point. If you were a stranger, I'd never have let you within a hundred feet of someone I was guarding."

Lucien hums at that… and then grunts when Mercy sits up and wraps her breasts around his cock, sliding her soft chest up and down his length while pushing them together on either side of his shaft.

"Good… eyes."

Mercy smirks and looks up at him.

"Not as good as yours, I suspect."

Lucien chuckles and shakes his head.

"No. You're right. You deserve that much honesty at this point… I can do more than just heal. I could, with the access to the right biology, make you powerful enough to destroy even Brainiac if and when he returns."

Mercy's breath hitches and she tries not to react too hard to receiving confirmation. Of course, Lucien continues on, giving her a contemplative look.

"That said… since you're making this transactional, what else do you have to offer in return besides your body?"

A little laugh escapes Mercy's lips at that. Of course just her tits wouldn't be good enough. He was still his father's son. However, Lucien was NOT a carbon copy of Lex Luthor.

Mercy had carried something of a torch for Lex for longer than she could remember. It was impossible for her to lie to herself on that front… the man was larger than life, singularly intelligent, and the perfect combination of driven, ambitious, and successful.

Lex Luthor was a catch that any woman would be lucky to have… which was precisely why Mercy knew she would never have him. Because Lex was also not an overtly sexual creature. Oh he certainly had his needs, which he took care of when necessary. One of those times had resulted in Lucien after all.

But Lex didn't often mix business with pleasure unless it was the pleasure of trying to kill Superman. Mercy, as his right-hand woman and closest confidante… never had a chance at actually becoming his woman.

The same could not be said for Lucien. Everything Mercy knew about the younger man made it clear that when it came to business and pleasure, he regularly blurred the lines to the point that they might as well not even exist. He had absolutely no issue with engaging in sexual relations with any woman who expressed interest. Mercy might have been his first, but he'd been a busy, busy bee ever since.

Licking her lips and looking Lucien in the eye as she continues to give him a consummate titjob with her breasts, Mercy smirks.

"Oh this? This isn't part of the deal. This is just because I know we both enjoy it."

Lucien snorts derisively, making it clear how much he believes THAT. Still, fortunately… her body was not in fact all Mercy had to offer.

"I'm offering up my loyalty, Lucien. And you know full well what that's worth. More than that… there might be things that 'Alex' decides he doesn't want to tell you. Things he'll consider keeping close to his chest. Things that, as Lex Luthor's right-hand woman, I know as well. Knowing that I'm by your side ready to call him on his bullshit will keep him honest."

It's not much, but besides her body, it's all she has to work with. She can see the gears turning in Lucien's head as he considers her proposal and what she's offering him. She can tell he's interested too. Deciding to take the initiative once more before he can come to a decision, Mercy pulls her breasts away from Lucien's cock and climbs into his lap.

Hiking up her skirt and sliding aside her panties is the work of moments, and then she's able to impale herself upon his member right there in the backseat of the limo. Lucien grunts in surprise before reaching up and grabbing her by the hips as she grinds herself down on his dick.

"You are… very eager to get in bed with me, Mercy. Is becoming strong enough to defeat Brainiac really all you want?"

Mercy pauses for a moment, her jaw clenching as she processes Lucien's words. She should have known he would be able to see through her at least a little bit. Gyrating her hips, the blonde lets out an explosive breath before being fully honest with the man who would hopefully be her new employer.

"What I want? What I really want is to focus on myself for once. I want to get stronger, not just to be able to kill that alien bastard, but also just for the sake of being stronger. I won't sugarcoat things, Lucien. One day you and I will part ways. But I can guarantee you'll hear from me well in advance on that subject. And so long as you hold up your end of the bargain, I'll serve you just as loyally and faithfully as I did your father until our arrangement comes to a close."

Lucien stares at her for a long moment consideringly. Mercy briefly wonders if he's going to reject her despite everything… but then he leans forward and captures one of her nipples between her teeth. The blonde lets out a gasp and arches her back, tossing her head backwards as he gives the nipple a good solid tug.

At the same time, his hands wrap around to more firmly grip her buttocks and before Mercy can really even register that, he's bouncing her up and down on his cock. A cut-off moan leaves her mouth before she's able to clamp her lips shut, but in the end she's still left whimpering and grunting through said lips as they fuck all the way to their destination.

Mercy wouldn't pretend like she felt the same way about Lucien as she did Lex or anything like that. And she'd been rather up front about him being a means to an end for her. But she would show him the same level of service, both professional and loyal, that she'd shown Lex.

She would just also show him another type of service as well, seeing as Lucien was much more receptive to this kind of affection than Lex Luthor had been.

And Mercy Graves was nothing… if not adaptable.
