A/N: Thaddeus and Natasha get down.

-x-X-x-

He really should kick her to the curb. Unfortunately, Thaddeus' biggest flaw is that he's a sucker for a beautiful face. Even more if its attached to a woman in distress like Natasha is right now.

"… I can heal you."

Natasha jerks hard, her eyes snapping up to meet his as they go wide with shock and just a sliver of hope.

"What?"

Sighing, Thaddeus runs a hand over his face.

"I can heal you, Natasha. I have the power to restore your womb and make it possible for you to become a mother."

There's a long silent pause as that hangs in the air between them, until finally Natasha manages to choke out a response.

"How… h-how long have you been able to do so?"

Ah. Yeah. He's half-tempted to lie to her and say he could do it 'all along', just to make her feel really bad about lying to HIM all this time in the first place. But the risk of her finding out the truth later on has him just being honest now.

"Just this week, actually. It's a recent development for both me and the woman who has healing powers. Which is why you have two options now."

Natasha watches him carefully as he crosses his arms over his chest and explains.

"My version of healing is… sexual in nature. If I cum inside of you and activate the power, that will almost certainly do the trick. But I'm not going to knock you up just so you can run away, Natasha. The second option is that we have my new friend heal you normally… and you leave. The healing will be one final payment for services rendered and as far as I'm concerned, we'll be square."

He initially intends to leave it off there, even ending the sentence with a sense of finality. But as Natasha stands there contemplating his words, Thaddeus can't help himself.

"… I'd like it if you chose to stay. Emma and I can protect you from anyone who tries to come after you. SHIELD or otherwise. And I'd be happy to be the father to your child as well, if you wanted it. But not if you're just going to disappear on me. So if we do this, if you have me be the one to heal you… then it's because you're joining me officially. For good."

There it is. He's laid all the cards on the table. Either way, Natasha gets her healing. If she wanted to take that option, he'd have Maddie heal her up and she'd be on her way. With the amount of boosts he's given her from their fucking, Thaddeus figures Natasha can probably handle most of what SHIELD or anyone else might throw at her. She's tougher, stronger, faster, and just plain better than what they're expecting after all.

But like he said, he does hope she'll stay. He doesn't want to lose her, as greedy and possessive as it might be.

"… You really do have the luck of the Devil, don't you?"

Thaddeus grins crookedly and shrugs.

"You don't know the half of it."

Natasha lets out a shuddering breath and steps towards him. Thaddeus uncrosses his arms, watching her as she places a hand on his chest and bites her lower lip, looking up into his eyes.

"You still want me, even after all the manipulation, all the lies?"

Nodding, Thaddeus swallows hard.

"I do."

"… And you'd protect me. You and Frost?"

Straightening up and squaring his shoulders, Thaddeus sets his jaw firmly.

"We would. And I mean that with every fiber of my being. You don't even have to do the sort of work you've been doing for us if you don't want to. Especially once you're pregnant. I'd rather you stay safe than risk yourself or our unborn child."

The red head's eyes widen ever so slightly at that, and her eminently kissable lips quirk into a coy smile as she lets out an airy laugh.

"You really do know just the right things to say, Thaddeus."

Thaddeus shakes his head.

"I'm speaking from the heart. I-mmph!"

Natasha cuts him off with a kiss, the gorgeous femme fatale going onto her tiptoes in order to plant her lips on his lips. At the same time, she wraps her arms around his neck, holding herself to him and pressing the softest elements of her figure to his hard chest.

Instinctively, his hands go down to her hips… and then circle around to her impossibly perfect ass, grabbing hold of her cheeks on both sides and giving them a good, solid squeeze as he lifts her up just a fraction of an inch more while they makeout with one another.

This, of course, naturally escalates to Natasha lifting her feet off the ground entirely and winding them around his waist, clinging to him and grinding her crotch into his crotch, rubbing her entire body against his body. Digging his fingers into her ass, Thaddeus walks Natasha over to the bed and turns, sitting down on it as they continue to kiss.

Finally, they have to come up for air, though far after what two normal human beings would need to break for. In fact, Thaddeus could have kept going… but Natasha, for all her enhanced physique, can only hold so much oxygen in her lungs.

Panting heavily, her chest heaving up and down, the Black Widow's bright green eyes glitter as she beholds him for a long moment, her lips puffy and full from the kissing.

"In case it's not obvious… this is me saying yes by the way. I'll stay."

He'd sort of gotten that much from context alone but hearing her say it aloud is still quite the euphoric feeling. Big grin spreading across his face, he kisses Natasha again… and then, when she grabs a fistful of his hair and pushes his head down into her bust, he happily goes for that as well.

Their clothes don't last long after that, Natasha's top and the shorts she was wearing while hanging out in her room quickly vanishing along with her panties. Thaddeus' own shirt, pants, and boxers go the same way. Before he knows it, he's worshipping Natasha's breasts with his mouth as she lays back on the bed and arches herself for him, moaning and pushing her chest into his lips all the while.

Swirling his tongue around one of her nipples, Thaddeus latches onto it with his teeth, biting down and giving it a firm tug that makes her groan and buck in appreciation. He finds himself already imagining her lactating, milk flowing into his lips… but not yet. They still have some work to do first.

And its work that Natasha is eager for as well. Her hands reach down and grab hold of his cock, stroking him the rest of the way to full mast in no time. Her legs, meanwhile, spread nice and wide to accommodate him, and soon enough she's guiding him to her cunt.

Heh, funnily enough… despite how many times they've fucked, Thaddeus doesn't think he's ever seen Natasha so eager. Even though every time they had sex, she was hoping that it might be the one to heal her and give her back her ability to carry children… that was different from KNOWING this would be the time.

His cock soon fills her cunt as Natasha pulls him into her and Thaddeus drives forward with the first thrust. The red haired femme fatale cries out under him, her moans more wanton than they've ever been before. Turns out, getting everything she's ever truly longed for really does it for Natasha Romanoff.

Her quivering form underneath him, from her full breasts to her tight abs to her hourglass figure… it all really does it for Thaddeus as well. He has a lot of beautiful women in his life and it wouldn't be fair to say Natasha beats them all out with her looks… but she's definitely in the top five.

Of course, he was never ever saying that out loud, lest some of his girls start asking him to name and rank said top five. No sir, he liked his balls intact, thank you very much.

And so did Natasha. As he pounds her into the bed, her legs curling around his waist again and his balls slapping against her taint, the red head lets herself truly go. She cries out in ecstasy, shuddering under him in orgasmic bliss as Thaddeus fucks her like there's no tomorrow.

Or rather, like there is a tomorrow. A tomorrow for her, for him… for them. A bright future with a bouncing baby boy or girl.

With that in mind, he definitely doesn't hold back. As soon as he feels his release coming, Thaddeus focuses on infusing this load of seed with the healing power he'd gained from fucking Maddie half a dozen times at this point.

Heh, he supposed unlike Maddie, he wouldn't be spending much time in hospitals or helping random strangers. Not when his least invasive healing method was a facial.

"Here it comes, Natasha."

As expected, just hearing him say that is enough to make her clench down on his cock hard as can be. Her pussy walls flex and squeeze along his length, which in turn takes him over the edge as he thrusts forward one last time before cumming inside of her.

The usual feeling of his mutation boosting the both of them is there of course, but there's something else alongside it as well. Natasha shudders under him, not from orgasmic bliss, but another sensation altogether.

"O-Oh… that feels… very strange."

As he finishes emptying his balls into her reconstructed womb, Thaddeus grins down at her somewhat cheekily.

"Good strange, or bad strange?"

She gives him a dry look, clearly thinking him something of an idiot for asking that sort of question. Then, she tightens her grip on him, her arms around his neck and her legs still around his waist as she begins undulating her body and gyrating her hips beneath him.

"We're not done yet. Have to… have to make sure."

That was fair. Who knew how much of his first load had to go to healing her after all. This next load, and the loads after… they would go directly to sowing her now fertile fields…

With a determined nod of agreement, Thaddeus begins to thrust in and out of Natasha again, causing her to gasp, moan, and shudder under him as they start going at it a second time. And then a third time, and a fourth time, and so on. No rest for the wicked and all that…

-x-X-x-

Its hours before they're both done, and by the time he's finished, Natasha is looking a little bit pregnant already from how much cum he's stuffed her with. In fact, he's pretty sure he's heard her sloshing a bit whenever she moves. Or maybe that's just him being silly.

Either way, they lay on Natasha's bed in a tangled mess of sweaty limbs, with Natasha draped over him and resting her head on his chest as Thaddeus brushes the sweaty locks from her face.

"… You're an idiot, you know that?"

Thaddeus raises an eyebrow.

"I've been called worse, I suppose."

Huffing, Natasha raises her head and looks him dead in the eye.

"I could have been lying you know. About wanting to stay with you and join your… faction or whatever the hell you want to call it. You shouldn't have been so trusting. At the very least, you should have made me let you probe my mind to make sure of my intentions."

Thaddeus frowns, even as Natasha taps his chest with a finger pointedly.

"Your genes are some of the most valuable genes in the world, Thaddeus. Your children will no doubt be just as powerful as you, if not more so. Taking the risk of you trying to hunt me down would have been more than worth lying to you just so I could make sure my unborn child inherited something close to your powers."

Humming, Thaddeus tilts his head to the side.

"That's a lot of words just to explain that you're not going to do that, Natasha."

The red head flushes and scowls.

"Idiot. I'm trying to teach you a lesson, damn it. You need to be less trusting and more cautious, otherwise you're going to continue to be taken advantage of. If not by me, then by someone else."

… She might have a point. But Thaddeus was having a hard time not smiling a bit goofily as she lectures him. In the end, he'd snagged the femme fatale and they both knew it.

"Alright then. What do you think we should do about The Cavalry and SHIELD? They're not going to stop are they? They're going to keep coming after us… and it's not likely that they'll just let you go either. But we also don't know if they even know that you've turned on them yet. This new agent hasn't made a move… so we still have a chance."

It was hard to remember at times that Shaw's death had been only about a week ago at this point. So even though so much had happened in the past several days, 'Shu Wong' was still just settling in, probably getting herself set up and trying to figure out the best way to both get involved with him, as well as figure out where Natasha's true loyalties lay.

In the end, undercover missions like this one could last months and were usually about being as subtle and cautious as possible to avoid being found out.

And that cautiousness… provided an opportunity.
