She’s already on top of him. As such, trying to usurp control from the gorgeous blonde femme fatale would probably only sour the relationship he was currently trying to build with her. At the same time, he couldn’t quite bring himself to hide his true nature from her either. He wanted to impress her.
 
But more than that… holding back his full potential wouldn’t actually train him up to be able to make Death cum any faster, now would it? No, to reach the point where he could take Death to bed and bring her to the heights of ecstasy, Lucien needed to push beyond his current limits. Again and again, as many times as it took.
 
Regardless, he lays back on the bed, allowing Mercy to take the lead and ride him. As she bounces up and down on his cock, Lucien groans his appreciation. It feels amazing having sex with a woman, even if she’s not Death. It feels even better not being constantly weakened by the pain from his past life. That said… he can’t help making something of a comparison.
 
Mercy is his father’s right-hand woman. She’s clearly far more experienced than him in every way, from life experiences to sexual experiences. Not only that, but she could kill him before he could even blink, even as he is now. She’s death-in-heels, really. However… she is not Death. She’s not the woman who met him at the end of his first life and sent him back to reincarnate into his own timeline. She’s not the beautiful, white-skinned Endless who told him that this was only the beginning… and that he would need to work extra hard if he wanted to one day stand equal to her.
 
In comparison to Death, Mercy comes up short. But that’s fine. It is what it is. Lucien is still going to learn everything he can from how she moves upon his cock, how she rides him and gyrates her hips across his crotch. His hands on her hips, Lucien watches with single-minded focus… something that Mercy Graves doesn’t fail to notice or bring up.
 
“Heh. Where does that determination come from, I wonder? You seem quite resolved, Lucien. Most men don’t take this so seriously. It’s just sex. And sex is all about feeling good.”
 
Lucien frowns, wondering how much he should really tell her. He can’t exactly come out and say he was training to be able to bring Death of the Endless to a climax, now could he? He would sound insane if he said something like ‘I want to make Death cum’. For a second, he considers just staying quiet… but for all that Mercy is clearly teasing him, it’s not a rhetorical question. He can feel it in her movements and in her body, that she’s starting to slow down as he remains silent. She’s expecting a response.
 
“… I want to learn how to please a woman, Mercy. And since you’re giving me this opportunity… I figured I could learn from you.”
 
Mercy’s brow raises at that, but his answer satisfies her interest and she starts to bounce up and down on his cock at a swifter pace once more, no longer slowing down. Humming as she rides him, the blonde considers his words for a moment before nodding.
 
“I see. You’re not quite as much like your father as I thought. Or rather… you’re your own man, aren’t you Lucien Luthor?”
 
Lucien flushes at that. It’s nice to hear, though he has to admit now he’s wondering why she’s saying so. Luckily, Mercy doesn’t keep him in suspense for too long.
 
“Heh. Lex isn’t the type of man to worry about others’ satisfaction. No… your father is the sort of man to focus solely on seeing his own Will carried out. If other people are… satisfied along the way, then that’s just a happy accident.”
 
Blinking at that, Lucien suddenly has a thought that makes his nose wrinkle. But Mercy is quick to notice this and correct the misunderstanding.
 
“Don’t get me wrong… my relationship with your father is purely platonic. We’ve never been physical with one another. Even still… I know some of the women he’s been with. And I know that their pleasure wasn’t something that ever came into consideration for him. If they… enjoyed themselves, it wasn’t because of anything your father did, but in spite of it.”
 
Well now. That was… huh. He didn’t know how exactly to take that. It sounded like learning Lex was keeping things from her had made Mercy more than a little bitter towards his father. He could probably use that… but later. Right now, he was more focused on what was right in front of him. Detecting this, Mercy just smirks down at him.
 
“But enough about him. You want to learn? Then I’ll be happy to teach you, Lucien~”
 
Her sultry, almost predatory tone definitely has Lucien paying attention, even as she proceeds to do her best to teach him all about her body. She shows him where to touch, guiding his hands to her breasts. She even teaches him about her clit. As Mercy bounces up and down on his cock, the blonde is lecturing him the entire while… which is certainly impressive, given she manages to keep her groans and moans to a minimum as well.
 
She’s maintaining a pretty calm attitude, even as her inner walls flex and clench down around his cock. Unbeknownst to the blonde femme fatale, Lucien is actually multitasking. Oh, don’t get him wrong… all of the information coming out of her mouth is great. He’s learning a lot from what she’s telling him. However… he also has his power to rely on as well.
 
With his abilities, Lucien doesn’t just have to take Mercy’s word for it. He can see how her body is reacting to what’s happening in real time. Every single moan and gasp is preceded by some sort of reaction within her biology, and Lucien rapidly learns just how to best use the tools he has at hand to make Mercy feel good. Even as she slides up and down his cock, Lucien’s fingers are working away at her as if like magic… and he can tell it’s having quite the pronounced effect.
 
At a certain point, Mercy slows to a stop, covered in a thin layer of glistening sweat and panting heavily, her chest heaving up and down as she licks her lips and tries to catch her breath.
 
“You are… an incredibly fast learner, Lucien. I’m getting close now. I wonder… how will you, mm, finish me off?”
 
Smirking at him, she purposefully moves up his length… and then slams herself down his cock. Then she does it again. Maybe she intends to make him cum before she can, but the truth is… he’s not going to cum until he decides he wants to cum. With that in mind, Lucien waits for the right opportunity… and then strikes.
 
His hand lances out and just as she’s slamming herself down on his cock again, he grabs and pinches her clit. At the same time, he lifts his hips with considerable strength, thrusting up into her from below. Mercy’s eyes go wide, and then go crossed as she shudders, orgasming explosively right there on the spot. The gorgeous blonde, his father’s right-hand woman and death-in-heels… damn near collapses onto Lucien’s chest from just how much he just blew her mind.
 
And the best part is, he knows it’s not an act either. He can see that she’s not faking it, that he really did make her experience what might have been the best orgasm of her life. Okay so that last bit was somewhat hyperbolic, and definitely an assumption. It probably wasn’t the BEST orgasm of her life. But then… if it wasn’t, that just meant Lucien had to try harder, right?
 
Mercy might have thought they were done, but she would be wrong. As she’s still recovering from her own earth-shattering climax, Lucien is already in motion. With a grunt and a single swing of his hips, he flips them both over and puts the blonde bodyguard on her back, right then and there. Her eyes immediately snap to his as she stares up at him, and he sees in her gaze the realization that he’s barely even winded.
 
“L-Lucien… what… w-what do you think you’re doing?”

She’s in no position to stop him right now, but she also makes no effort to do so either. He hasn’t cum yet after all, and Mercy still has her pride as a woman, he supposes. Regardless, Lucien grins down at her and shrugs.
 
“I figured I’d put your lessons into practice while you rested a little bit. Don’t worry… I’ll take it from here.”
 
Sliding his hands down to Mercy’s thighs, Lucien lifts her legs up into the air as he settles into place, his cock still impaled inside of her weakly flexing cunt. Chest heaving, the blonde looks up at him with a narrowed gaze… but he quickly wipes that away as he begins to fuck her. Using everything she’s taught him so far, he pounds into Mercy with a single-minded focus. As well as the all-knowing understanding of her body that comes with his powers.
 
Lucien is in charge now, but he’s still focused on Mercy’s pleasure. Sure, he made her cum once… but what was better than one orgasm? Two orgasms, of course! And what was better than two orgasms? Eh, you get the idea.
 
He wasn’t going to let up. He wasn’t going to stop. Not for anything. If he wanted to one day overcome Death in the way he’d just overcome Mercy Graves, he needed so much more practice it wasn’t even funny. He needed experience that could only be provided by going out and doing the deed. That was where Mercy came in. That was what she represented to him right now.
 
… Of course, she was also important to him in other ways. And it just so happened that his practice involved making her reach the heights of ecstasy again and again. So weren’t they both winning here?
 
Certainly, Lucien feels pretty damn good as Mercy cries out, her hands clawing at the bedding above her head, her head rocking backwards, and her spine arching as she thrusts her tits up into the air. Making sure not to neglect said tits, Lucien leans forward and suckles at them both, alternating between her nipples as he slurps and bites at her teats.
 
Mercy, he discovers through trial and error, is the type of woman who likes a little pain with her pleasure. Even as he does things like bite at her flesh, something that should have hurt… her reactions show she’s enjoying it. Her biology is an open book to him, and through it Lucien is able to play her body like a finely tuned instrument. His growing understanding of his powers is making him a master at the sort of bedroom play he and Mercy are currently engaging in. It’s the most basic of sexual antics, the most vanilla thing in the world for him to just fuck her missionary style like this… but then, they all have to start somewhere, right?
 
Lucien makes Mercy cum a second time upon his pistoning prick. He makes her cum a third time too. He watches as she climaxes a fourth time and thinks that she might be nearing the end of her rope. He’s eager to take her there. He’s eager to push HER past her limits, even if it doesn’t seem like they’ll be pushing past his right now.
 
However, before he can bring her any closer to half a dozen orgasms, Mercy grunts, catching his attention as she suddenly leans up and drapes her arms over his shoulders, clasping her hands together on the nape of his neck.
 
“You must… be getting close… Lucien. Need… need you to o-only cum in my mouth, g-got it?”
 
He’s actually not that close at all. About as close as he’s been the entire way through in fact. He decides when he cums. His control over his own biology is absolute. But… he can tell that she’s not taking no for an answer here. If he pushes the issue, he really will burn up any good will he’s managed to get so far with her.
 
Nodding, he pulls out with a grunt as she lets go of him, flopping onto his back on the bed. Then, he watches with carefully hidden movement as Mercy shakily gets up onto her hands and knees and takes him in her mouth. He considers very briefly making her work at it long enough for her jaw to start to ache, but no. No more funny business.
 
He blows his load down her throat a few seconds later, watching as she swallows every last drop of his cum. She drinks his seed down with ease, and it makes Lucien consider if he could have put something else in his jizz… maybe a pick-me-up or something? He could technically modify his ejaculate however he wanted. Something to think about for the future.
 
For now, he continues laying back on the bed, feeling pretty good about himself and the situation. That is, until Mercy pulls back from his cock and gives him a look. Still holding his dick in one hand, the blonde femme fatale strokes it up and down… but suddenly seems a lot more dangerous all of the sudden. Like she’s gone from lover to fixer in an instant.
 
“Now that that’s out of the way… let’s talk about how exactly you knew there was a nanochip in your father’s head, Lucien.”
 
He’s too relaxed at the moment, so he’s not fully controlling his reactions when she suddenly says that. As such, his eyes go as wide as saucers as he realizes that he’s been caught out. He can only lay there, feeling like a deer caught in headlights. Shit. In hindsight, it was rather obvious that Mercy would want to know exactly how he knew about the nanochip. Though… that she’d waited until now… hm, had she thought to exhaust HIM?
 
Had all of this been to tucker him out so he would be more susceptible to her questioning? Had he inadvertently foiled her plan and forced her to start this interrogation at a disadvantage? It certainly felt like it. That didn’t change she’d asked him anyways and now he had to decide how he was going to answer her.
 
He’s not going to blow her off. That much, Lucien decides immediately. Technically he might be able to, given she was so tired. He could handle her, in her current state. But he’s not going to, because there’s no reason to. Not yet anyways. With that decided, he just has to decide how much information he’s willing to give her.
 
Slowly, Lucien nods to both himself and Mercy, to show he’s going to explain. Yes… he could still talk his way out of this.
