A/N - In honor of Seb's birthday - please enjoy some Bucky smut :3

I hope you guys like it... *hides face*

Bucky woke up, reaching out for Alex only to find that she wasn't beside him. He sat up suddenly, terrified that he might have dreamt their escape, "Alex?" he called out, still half asleep.

"Yeah?" came a small voice, and Bucky noticed that she was sat in a small armchair by the window, staring out.

"How come you're up already?"

"I'm not sure it's 'up already' if you never slept." Alex didn't turn to face him when she spoke.

"You didn't sleep?" She shook her head. "Hey, come over here." He said when she finally turned around, tapping his hand on the bed next to him.

Alex walked over slowly, climbing in under the covers and resting her back on the headboard. "What's wrong?" Bucky asked, moving to sit in front of her.

"I killed them."

"Who?"

She looked down at her hands, "The guards on my cell. I killed them, Bucky."

"How come you never said anything earlier?"

Alex shrugged, "I guess the adrenaline of getting out meant that what I did didn't really sink in."

"Alex, you had to." He took her hand in his, using the other one to tilt her chin up so that she looked at him.

"Did I?" Tears began to fill her eyes. "I stabbed one of them in the back, but the other one I got in the leg and then I just knocked her unconscious and left her in there with the fire. She would've burned."

Bucky put both hands on her cheeks, inching his face closer to hers and looking her straight in the eye. "You had to do it to get out."

"I get it now." Alex said after a moment.

"What?"

"What you said to me after you killed those guys. That if it saved me you'd do it over again." Alex stared at him, wide-eyed. "I killed them because I needed to get you out. And I'd do it again."

He wiped away the tears that had begun to fall from her eyes. "You shouldn't have to. You shouldn't need to be this person." He took his hands away, eyes serious, "I'm sorry. This is all my fault."

"Yeah, it is." Bucky was taken back by Alex's sudden admission. "Because the only person I love is a huge security risk to my life." She smiled, receiving a small, if not slightly unconvinced smile in return.

"I'm gonna go take a shower." Bucky said, getting up and going towards the bathroom. "Try and get some rest."

When the door closed, Alex lay down and within moments she was asleep.

She woke up in an empty room, Bucky had gone. She couldn't have been sleeping long though, as when she went into the bathroom, the shower was still steamed up from when Bucky had used it.

After a quick change, Alex left the room, moving towards the lounge before she stopped, hearing voices coming from inside one of the smaller rooms.

"So you think they've moved base?" She heard Bucky ask.

"Most likely," Another voice replied, and peeking around the corner for a second she saw that it was Steve. "After we attacked they would've moved to another location."

"And you think it's there?"

"We got some intel that said they were headed north. This is the only place big enough."

"So we go there."

"Go where?" Alex took her chance to walk into the room, interrupting their conversation as all eyes landed on her.

Steve's eyes were wide as he rubbed the back of his neck in an awkward attempt at looking casual, "Alex, hey!"

"Me and Steve were just talking about going on a supply run tomorrow." Bucky only managed to look slightly more casual than his friend.

They were terrible at lying and Alex wasn't buying it. "A supply run to find Strucker?" she 'asked'.

Steve chuckled nervously, "No, why would you-"

"I heard you talking." She cut him off, partly so he didn't have the chance to come up with some lame cover, but mostly to put him out of his misery. Steve was possibly the least comfortable liar she'd ever seen - it looked as though his mouth couldn't cope with false truths.

"Look, we've been trying to find Strucker for a long time, Alex." A man wearing a lot of leather interjected; she hadn't didn't even noticed him there.

"And who are you exactly?"

"Nick Fury, ex-director of S.H.I.E.L.D." He said sharply, before continuing, "And now we know that he wants Bucky, and to an extent you, we can-"

"What? Use us as bait?" Alex snapped.

Fury stepped closer to her, "If we have to, yes!"

Alex laughed in outrage, "Oh! So, that's why we're here?"

"No," Steve snapped, jaw clenching as he stared daggers at Fury. "You two are here so that you're safe."

"Right now, I'm having a lot of trouble believing that."

"Alex," Bucky cut in, "If we do this we could stop Strucker once and for all. We could stop running."

She sighed, turning to him, "I know that he needs to be stopped but it's not like he's just gonna let us waltz in there and take him out. He wants you Bucky, and he'll do anything to get to you - he made that pretty clear."

"Yeah, I know. And that's why you're gonna stay here." He lowered his eyes.

"What?!" Who did he think he was, her father?

Bucky sighed before looking at her sternly, "He can't use you as leverage if you're not there."

What, was she a liability now? "I can't believe this!" Alex threw her hands up, turning around and walking away from the little meeting.

"Alex!" She turned back to find Steve running after her, "Stop!"

When she didn't, he moved in front of her so she couldn't get past. "Look, I've known Bucky a long time."

"I'm well aware."

"Point is, he's protective of the people closest to him. And he'll do anything to keep them safe." Steve looked like he was trying to say something more, but couldn't find the right words. "What I'm trying to say is that Bucky doesn't want to lose focus during this mission." His brow creased, as though that didn't come out quite how he'd meant it.

It was nice that Steve was trying to stick up for his friend, but right now Alex really wasn't in the mood. "I know, but I'm not some hopeless case, Steve. I can take care of myself." She said, giving him a tight, half-hearted smile before walking away.

After walking around the building for a while, Alex found a stairwell. She climbed right to the top and opened the fire door to the roof. It was midday and the sun was high in the sky, though the air was cool. Reaching out, she picked up a discarded brick and used it to prop open the door - she wanted to be alone for a while, but not locked on the roof.

If they needed her out of the way, then she'd stay out of the way.

Alex sat on the floor, before lying back on the cold concrete, looking up at the clouds. it was something that she used to do with her parents when she was little - one of the only clear memories she had of both of them - looking at the sky and pointing out the shape of the clouds. It could be anything from a light-bulb to a tortoise in roller skates - whatever they could think of. Doing this now relaxed her a little, taking her mind off everything that was happening.

But it made her think - would they be proud of this person she'd become? The things she'd done? The choices she'd made?

Her eyes began to well up at the thought of her parents, but she just carried on watching the clouds and taking deep, even breaths of fresh air.

She didn't go back inside until it started to get dark, retracing her steps back to the room. There was no one around except for a few agents still working at their computers. Did they ever sleep?

Opening the door, she stepped into her room, coming face to face with an angry looking Bucky, who sprung out of the chair he'd been sat in, "Where the hell have you been?" He said with a tone reminiscent of an annoyed parent.

She rolled her eyes, "I went for a walk."

"You went for a walk?" He raised an eyebrow incredulously, "Where?"

"Around." Alex narrowed her eyes at him, "I thought it was best that I stay out of the way. You never know who might want to use me as leverage."

Bucky sighed, "Alex, I know how that sounded, but I just want-"

"To protect me? Keep me safe?" She snapped, "Stop me if I guess."

"Don't be like that!"

"Like what, Bucky? Because last time I checked I managed to get myself out of that cell just fine. I killed people for Christ's sake! I can take care of myself!" She would've continued but Bucky covered her mouth with his hand.

He looked at her, "I know, that's what I'm worried about. I don't want you involved in this anymore than you are now. Alex, being involved in this world - it changes a person. And you are so perfect the way you are right now."

Eying her carefully, he slowly removed his hand, "I want to come with you guys." Alex said softly.

She obviously wasn't giving up, "I'll talk to Steve and Fury about it. But if they say no, you stay. Agreed?"

"Agreed. But only if they both say no."

"...Fine." Alex pulled Bucky close, pressing a kiss to his lips. "You're really stubborn, you know that?"

"Yep." She smirked, biting her lip and leaning into Bucky as her hands began to rail down his arm.

He arched a brow at her, "Alex, you need to sleep," he said, pulling away.

"I can sleep after." Alex's hands played with the hem of his shirt, causing Bucky to take a sharp intake of breath as her fingertips brushed over his skin. "And I'm sensing that you don't want me to stop."

Bucky grabbed her hand before she could touch below the belt. "Stop." Bucky's voice was low, and though it sounded like a warning, Alex took it as a challenge.

"Make me."

He narrowed his eyes, hands gripping her waist, not hard, but tight enough to hold her still. Alex wasn't sure what his next move would be, but nevertheless she held his intense stare, her fingers still stroking the skin under his shirt.

Bucky's grip tightened, pulling her towards him and bringing their lips together in a hungry kiss. Despite his earlier protests, Alex knew he wanted this just as much as she did. But it was still sweet that he was trying to be a gentleman about it

Her hands gripped the hem of his shirt and pulled it over her head, dropping it on the chair that he'd been sat in. She shrugged off the open shirt she'd been wearing and then pulled her tank top over her head, before pulling Bucky back to her. She could already feel his arousal pressing against his pants, and she smiled against his lips.

"Maybe I should go to sleep, doesn't seem like you're that into it." Alex teased, turning away from him, only to have him grab her hand.

"Oh no you don't. You started this," he said.

Alex smiled again as Bucky took over pulling off his boots and pants. She quickly rid herself of her own, thinking how nice it was to not be sleeping on a floor listening for potential attackers, as she locked the bedroom door.

"Alex?" Bucky called out behind her and she realised he was already sitting on the bed, waiting for her.

She walked toward him, crawling along the mattress on her knees. He reached his hands out for her, grasping her around the hips. She leaned over him, kissing him as she pushed him down onto the bed. Alex trailed down and teased his nipple with her tongue, smiling when she felt him shiver, hands tightening on her waist.

Bucky started to sit up as though he were going to try to shift her around. "Don't," Alex protested. "As you were soldier, we're doing things a little differently this time." He was stiff for a minute, before he finally lay back down again. Alex peppered his chest with kisses and licked a trail down his stomach.

"Alex, what are you doing?" Bucky growled, cautious of her movements. But Alex just smiled up at him before taking him into her mouth, hearing him groan loudly.

"I'm pretty sure girls in my day didn't do this," he murmured. Alex didn't stop though, and the fact that he roughly buried the fingers of his (thankfully flesh) hand in her hair and tugged at it lightly told her that he didn't really want her to stop. And after a moment she felt Bucky's body still as he exploded in her mouth. "Wow," He panted.

"Welcome to the future," She crawled up his body and he leaned up to kiss her.

"Just...wow."

Alex leaned over him and Bucky's lips found her jawline, running over her neck and collarbone and up to her shoulder. Moving back a little, Alex got into position and eased herself onto him, grinding down on him and gasped as the sensation of that mixed with the feeling of Bucky's teeth sinking into her shoulder reacting to her movements on his still sensitive body.

He responded by wrapping his hands around her waist, and gripping tightly enough that Alex was sure it would leave bruises, helping to steer her movements to match his own. They moved together in sync, Bucky's lips finding hers again. He bit her bottom lip as she had done to him the first time, making her tug at his long hair, eliciting a groan from deep in his throat.

Bucky thrust deeper, becoming more comfortable with his movements, keeping Alex close to him, skin on skin as the heat built between them. Alex found her release at just the moment Bucky found his and they came, shaking, together. He closed his eyes, leaning his forehead against hers as their breathing calmed. When Alex finally moved, she slid just to the side of Bucky, one leg and one arm draped over him.

"I don't want to lose you," Bucky said after a few minutes, placing a kiss on top of her head.

"I'm not going anywhere," she said, hugging tighter around him. "I love you, Bucky."

"I love you too." He pulled the covers over them and wrapped his arm around Alex's waist as she drifted off to sleep.
