The portal had barely closed behind them when his lips were at the base of her neck his arm wrapping around her waist to pull her against him. She leaned into his support, her fingers threading into the hand at her waist, that wonderful electrical feeling passing over her skin.

I don't think I'll ever get used to this. Not with him.

She turned and he kissed her with an eagerness that made her smile, his hand gently pushing her back the few feet to the bed as he lifted the hem of her shirt. The material came off over her head as the back of her knees collided with the mattress, those deft fingers of his already working on the button of her jeans and she lifted a hand to his shoulder to steady herself while she quickly toed off her shoes.

There was a predatory gleam in his eye that had her swallowing thickly, a reminder that though he was good and kind, Steve Rogers was a dangerous man.

It shouldn't turn her on this much, but oh god, it did.

Shimmying out of her jeans, she scampered back on the bed, watching raptly as he pulled his shirt off.

Probably will never get used to that either.

His shadow fell over her as he join her on the bed, his body covering hers with one of his knees pressing between her legs. It was almost habit at this point, how her hand touched the sides of his neck, sweeping down over his shoulders and chest, following the path she'd once watched a drop of water take standing out in the jungle near a lake of Wakanda.

It felt like a lifetime ago.

His head lowered, his mouth falling to her collar bone as one hand trailed down her waist and thigh, then back again, leaving her skin buzzing. She could feel the hard length of him pressed into her hip through his pants and she gently rolled herself against him, causing the hand at her thigh to spasm as he inhaled sharply against her. Her own pulse raised in excitement, her fingers starting to work on the button fly of his jeans.

She knew they were rushing but it was like there was a pressure at the base of her spine, a want, a need in a way she hadn't felt before... one he seemed to be mirroring as he moved to shuck off his remaining clothes before reaching to hastily remove hers. Faintly her brain registered the sound of lace ripping but Darcy was already sliding her hand up the back of his neck pulling him to her, a soft sigh escaping her lips when he finally settled between her thighs. Heat pulled in her belly and she unconsciously moved her lower half against him in small, restless circles. His hips surged forward in response, stars erupting behind her eyelids as he pressed intimately against her. She heard his shaky breath as she reached between them, taking him in her hand to position him.

Pushing slowly into her, his chest against hers, she could feel his stuttering intake of breath against her body and she shifted to allow him to settle more fully. Her head tilted back and she closed her eyes to just enjoy the sensation, the fullness and warmth once he was completely sheathed within her. She opened her eyes when after a few more second he still hadn't moved.

Steve was looking all over her face as if trying to memorize her in this moment, and for the first time she could see the wear of time in that usually clear gaze.

"Darcy," he started, his voice a rough whisper. "I want you to know, this isn't just-"

She leaned up, cutting his words off with a gentle kiss. She couldn't hear him say it, that this meant something, that this wasn't just him checking off something on his list or even just an act of defiance aimed at the universe saying they were still here, still alive.

She knew it wasn't. But any talk of the future would bring the uncertainty of theirs into blinding clarity and she didn't want his name brought into this moment.

This belonged to them.

"I know," she said against his lips before pressing small kisses down his jaw and neck before sucking hard over his pulse. He moved his head sharply down to catch her in a kiss, the ferocity of it taking her by surprise.

If she would not let him tell her, it seems he would show her instead. His arms wrapped around her, his embrace spanning her entire back. She should have felt claustrophobic but instead just felt remarkably protected.

And then he started to move.

It was a little halting at first until he started to move in earnest, the bed frame starting to sway. It felt wonderful, that molten warm feeling starting to spread to her limbs she clenched around him in response, illicit a choked sound that had him burying his head in the curve of her neck.

"You feel amazing," he murmured into her skin and she couldn't help the wicked smile that curved her lips as she hooked one leg high over his hip and she could feel his breathy chuckle.

The change in angle had her pulling in deep breaths, each exhale allowing the coil in her belly to pull tighter and tighter and she buried her face in his chest, her involuntary moan vibrating across his skin. The hand at her thigh moved underneath her, spanning over her lower back and lifting her to get a deeper angle, his thrusts becoming more forceful. Her head fell back against the bed, legs wrapping around his waist. The hand that had been supporting his weight threaded into her hair, the slight pull giving her just a hint of pain that was enough to send her over the edge, her orgasm passing through her in waves.

"Fuck," he murmured in her ear, his hand tightening against her scalp, hips pressing into her with two more deep thrusts as his body tensed over her. She carded her fingers through his hair and trailed them down his back, his shoulders twitching in a small shiver. In retaliation he rubbed the scruff of his beard against a ticklish spot that had her yelping and squirming but his hold was iron.

"Careful," she said in mock seriousness, "I'm pretty sure you don't want me to portal with us in this position."

"Fair enough," he said pulling back to smile at her, this time looking as youthful as she'd ever seen him. Without thinking, she reached up, touching her fingertips to his cheek.

If I can time travel, she thought, I want to come back here, to this moment.

He kissed her, this time more gentle, less insistent before sliding off of her and pulling her against his chest, his body curling around her. They lay like that throughout the night, his nose buried in her hair, arms banded around her and a palm pressed over her heart.

Yours, she thought just as sleep overcame her. It's yours.

Steve did not, could not sleep, instead taking the time to replay every moment he could recall between them.

He had barely noticed her at first, that day in the conference room, his focus initially on Dr. Strange and his abrupt appearance. She had been slouched in her chair, arms folded over her voluminous sweater, hair mashed flat under her knit cap, and scowling. He hadn't believed either of them, that she, this perfectly ordinary young woman had lifted Mjolnir... he who should know better than anyone a person's exterior tells you nothing of the worth within.

It had taken a whole, oh what was it, fourteen hours for his suspicion of her to wane. Seeing her awkwardly eat a muffin with watering eyes and embarrassed chipmunk cheeks, he came to the firm conclusion that she was no nefarious manipulator. And then she had moved to leave, the ground vanishing beneath them and she had made him laugh for the first time in ages. He almost did not recognize the sound as it forced itself through his vocal cords and she ran from the room, leaving him bewildered in the middle of the table.

Bewildered... it was pretty much his perpetual state from that point forward when with her. She made him want for a future he thought he'd long let go of, things he was certain would join his list of those not meant to be.

Maybe... he dared to hope.

It felt like the most dangerous of all the tasks ahead of him.

He nuzzled the area behind her ear just as their peace was dash by ear splitting sirens... the ones reserved for one purpose and one purpose only.

Thanos.
