This is supposed to be pretty early on in Clarke and Natasha's relationship.

I promise to keep you warm

Natasha Romanoff understood Clarke Griffin. Understood her more than Natasha could say. Clarke always joked that Natasha was a psychic, that she could read Clarke's mind. But Clarke had no idea. No damn idea.

Natasha understood Clarke. Her Clarke. She loved the younger woman. So much.

But she also understood Clarke. Completely.

Clarke kept a façade up of not caring of being hard and ornery. But there was more.

That was essentially people in a nutshell. No one was only one thing exclusively. They were always more than just one attribute.

Clarke was…pessimistic, brooding, angry, murderous, wrathful, vindictive, vengeful, misanthropic, nihilistic.

But she was far more than that as well.

She loved so unconditionally. So fully.

She loved everything about the world. She despised humans, in the masses-but liked them selectively, but she loved the world itself. Loved nature, loved animals, loved everything around the world, save for humans.

She amazed Natasha, truly.

Clarke loved so fully and with so much joy, when she wasn't broody, anyway.

Clarke had told Natasha that she had had sex multiple times, before meeting her romantic partner soulmates. She had had sex with both men and women. But she said that she had never experienced anything like sex with Natasha.

Natasha had smirked upon hearing that, her ego, needless to say, properly stroked.

However, she didn't need Clarke to tell her that, she knew that already.

Not that she was that egotistical. She was confident in her abilities to seduce and to fuck someone into the bed till they were unconscious. However, she didn't need Clarke specifically to tell her that.

For Clarke already told her that with every moan. With every scream. With every thrashing. With every arch of her back off the bed. With every roll of her eyes going back into her head. With every tremble under Natasha's hands and mouth.

And of course, Clarke passing out after all of the pleasure that Natasha ruthlessly drove into her, only confirmed to Natasha what she knew already.

Natasha currently had her left hand fixed around the front of Clarke's throat, choking her out, at Clarke's request, her fingers thrusting in and out of Clarke hard.

Clarke shook under Natasha, as Natasha's fingers rubbed and stimulated her clit, Natasha rubbing her clit against Clarke's leg, both of them completely naked, covered in sweat and Natasha had already fucked her within an inch of the younger woman's life.

She had already wrung Clarke through not six, not seven, not eight, not even fifteen, but thirty-five orgasms.

The thirty-sixth was on its way.

There was the benefit of Natasha having been pumped full of the super soldier serum.

She had an endless amount of the energy that a normal human being, without the super soldier serum wouldn't have.

Natasha could go on like this for hours and hours, but she knew that Clarke wouldn't be able to-Clarke had more energy and strength than Natasha ever would, but even she had her limit at the torrent of pleasure she could take. Even though Natasha was more than happy to give her a thousand more.

Natasha smiled dangerously as she watched Clarke thrash, gaping, arching, moaning quietly.

"Do you want to cum again, malyshka?"Natasha asked in what she knew was a threatening voice, but she knew turned her beloved on far more than it should have.

Clarke tried to nod weakly and she gasped out pleadingly, "Yes…please, yes, mommy….."

Natasha grinned, thrusting in and out brutally against Clarke, stimulating the younger woman in a ruthless pace, sending Clarke over the edge as she squeezed Clarke's neck tighter, leaning forward and biting Clarke's left shoulder hard.

Clarke gave a choked scream as she climaxed again, her orgasm tearing through her as she clenched around Natasha's fingers, hard and she bucked wildly under her lover.

Natasha chuckled as she unlatched her teeth from Clarke's shoulder, pulling her lips away as she felt Clarke fall limp against the bed for the thirty-sixth time, a smirk on her face, watching Clarke collapse against the mattress.

Natasha grinded herself against Clarke, pushing herself to the brink and coming against the younger woman's leg, moaning as she did.

When Natasha recovered, she pulled her hand from Clarke's throat, and sat back, smirking at her lover. She didn't say anything. Nothing needed to be said. Natasha just liked watching the younger woman like this, shaking and trying to recover from the pleasure that had washed over her, assaulting her.

Clarke panted as she whispered, "Holy shit…holy shit…Nat, do you want me to-?"

"No," Natasha said, chuckling, "Don't worry, love. I just want us to stay like this for a while, if that's okay, malen'kiy. Besides, I got off against your leg."

And she had. She'd been humping Clarke's leg over and over, while choking Clarke and thrusting her fingers in and out of the younger woman.

Clarke nodded weakly.

"Yeah," she panted, "Okay. Um…tired."

Natasha chuckled, "Well, I certainly will take that as a compliment."

Clarke gave a small, tired giggle. Natasha's smile widened.

She loved seeing Clarke like this. She loved looking at Clarke in general. But seeing Clarke like this? Loosened up completely? Limp? Vulnerable? It was so, so beautiful. So soothing and calming for Natasha.

It soothed her so much to know that she could make Clarke like this, give her this, make her this loosened and unwound.

"I want to lie down with you for a little longer, if you would let me, malyshka,"Natasha purred lowly, "May I?"

Clarke weakly nodded. "Okay, okay, mommy," she said.

Natasha smiled and draped herself over Clarke's body, lying down on top of her, pressing her lips to Clarke's right ear as her young lover panted, remaining still, save for her heaving chest. Natasha whispered into Clarke's ear, "Are you warm, love?" She already knew the answer, but she wanted to hear Clarke's answer anyway.

"Yes, mommy," Clarke answered weakly, closing her eyes, "I'm so warm."

Natasha smirked.

She wanted to keep Clarke warm always. Warm, wanted and loved.

"I love you, moya devushka."Natasha purred.

She heard Clarke whimper quietly, and Natasha felt her heart warm more than it already had warmed up, if that was possible. She knew how overwhelmed Clarke got by any words of affection being given to her, and Natasha was more than happy to take advantage of that particular weakness of her beloved.

"I…," Clarke whimpered, "I l-lo-"

"Shh," Natasha crooned, "You don't have to say anything, love. I know. I know." She kissed Clarke's ear and rested her head against Clarke's neck, "Get to sleep, dorogoy."
