Main Masterlist | Devoted Possession (Part 2.)
It was never supposed to happen like this.
You never expected to be in the situation you were in now; curled in the arms of Bucky Barnes, eyes barely open as you lay against him. The warmth of his body acts as a shield from the world. At first, you were just part of the team because it was just a job. Just a mission, something you’d done countless times before, working alongside the Avengers to take down the bad guys. But then came Bucky.
It didn’t happen all at once. It was subtle, like the slow spread of a virus, but by the time you realized what had changed, it was already too late.
The beginning was almost innocent. Almost.
When you first met Bucky Barnes, you had no idea that he would become the center of your world. At first, he was just another soldier, another teammate. A broken man struggling to piece himself back together. But there was something about him that intrigued you, something hidden behind the dark intensity of his gaze that drew you in like a magnet.
You didn’t mean to get so close. You honestly didn’t mean for it to happen. But it did.
Because Bucky was different. He wasn’t like the others. His scars, both physical and mental, made him stand out in a way you couldn’t ignore. He didn’t pretend to be perfect. And you didn’t want him to be. The cracks in him made him… real. He wasn’t like the men from your past who had lied, manipulated, and betrayed. He wore his flaws like armor. And, for you, that was everything.
You started off by offering quiet companionship. A kind word here, a soft smile there. You knew that Bucky wasn’t someone who trusted easily. He had been through too much. So, you didn’t force it. You just… waited. Watched him from afar, letting your presence be a steady, comforting thing in the chaos that surrounded him.
It didn’t take long before Bucky began to notice you. It wasn’t obvious though at first. He would give you a nod here and there, maybe a short, clipped sentence when the mission was over. But it was enough. It was enough to make your heart race every time he glanced in your direction, to make you feel like he saw you. Really saw you.
And then, one day, it happened.
You were on a mission together, as usual, when the two of you got separated from the rest of the team. It was a small thing, just a few minutes of being alone in a quiet corner of a dark building, but it was enough for something to shift. Bucky looked at you in a way he hadn’t before. No longer as a teammate, not as someone to protect or be protected by, but as something else entirely. Something you couldn’t quite place but felt deep in your bones.
It was there, in the silence, that you took your first step.
You smiled at him. “Are you okay, Bucky?”
He blinked, but then something softened in his eyes. He looked away briefly, like he was trying to hide his vulnerability. “Yeah, I’m fine.”
But you knew better. You could always tell when someone wasn’t being honest, and Bucky… Bucky was never truly fine. You could see the cracks in his composure. It made you want to protect him. To shield him from whatever haunted him, even if that meant making sure no one else could ever touch him.
It wasn’t malice. It wasn’t some dark desire to hurt others. But it was a need. A need to care for him. To love him in a way that no one else could. To make sure he was only ever yours.
The thought was almost comforting, becoming something you would rely on and remind yourself of often. The world was big, but when you were with Bucky, it felt so small. Just the two of you. No one else mattered.
Your affection grew slowly, like a seed planted in the quiet moments. You would find yourself lingering near him, watching him without his knowledge, memorizing the way his jaw tightened when he was thinking too hard, the way he would instinctively hold things with his normal arm instead of his metal arm and you, being ever so observant, saw the way he flinched when someone made a joke about the metal appendage. You wanted to shield him from those moments. You wanted to be the one he turned to, the one he could rely on, even if you two just sat in silence.
But that was the thing, wasn’t it? You didn’t need to be loud about your affection. You didn’t need to be overt. You were like a shadow, always there, always watching. Just enough to make sure he never strayed too far from you. To ensure that no one else could have him, not when you were so willing to give him everything. Your love was sweet, soft even. But beneath it was something darker, something that always kept a careful eye on the world around you. You’d smile at others, be polite, make them feel comfortable. But you were always watching. Always waiting.
But you weren’t the only one watching. Bucky noticed you, just as keenly. He wasn’t blind to the way you lingered around him, the way your eyes followed his every move, the way you seemed to keep track of his moods as if you could anticipate them before they even formed.
But it didn’t scare him. No, it intrigued him. Because, as much as Bucky was a soldier with a dark past, he craved that connection. He craved someone who saw him, who understood him without him needing to explain.
Bucky’s obsession was different. It wasn’t that he was unaware of his feelings, but they were more visceral. More possessive. The way he looked at you when someone spoke to you for too long, the way his hand would always drift to your back when others tried to get too close. He was marking his territory. He didn’t just want you. He needed you.
And when he needed something, it wasn’t just for a moment. It was forever.
Therefore, one day when it was late in the night with a mission recently finished and the team dispersed to their own things, you weren’t ready to go back to your room. Not yet.
The hallway was empty, lit only by the dim flickering of old lights above. You hadn’t even noticed Bucky following you, your footsteps echoing softly on the cold concrete floor. It was a rare sight to see someone as observant as you being lost in thought. Your mind was still running through everything: the mission, the battle, the faces of the enemies you’d taken down. It was all so mechanical, so numb.
But then, you finally noticed it. The sound of boots on the floor, slow but deliberate, the familiar thump-thump-thump that you’d come to associate with him.
You didn’t have to turn to know it was him.
“Are you okay?” Bucky’s voice was low, soft, but the underlying tension was palpable. As always, he’d been the one to watch you, the one who noticed when you slipped into yourself, when you started retreating into that space where everything felt too overwhelming.
You didn't respond at first. Your chest tightened and your thoughts were spinning. You desperately wanted to reply, use this moment to talk to him. But you couldn’t, not now. Instead, you kept walking, your shoes tapping against the floor in a steady rhythm. You didn’t want to face him. Didn’t want to let him see the cracks forming inside of you. But you knew he wouldn’t let you get away that easily. He never did.
He caught up with you, walking just behind you now, close enough that you were sure he’d run into you if you stopped. The air between you thickened with each step. Then, without warning, his hand shot out and grabbed your wrist, stopping you in your tracks.
The sudden contact startled you. You whipped around, meeting his gaze to see those piercing blue eyes, full of questions, full of something more.
Bucky didn’t say anything for a long moment, just watching you, his grip on your wrist not letting go, as though he was afraid you might slip away if he loosened it. And maybe he was right.
“You’re not okay,” He said finally, his voice quiet but intense. “I can see it. You’re not okay, and you keep pretending you are.”
You swallowed, your throat tight. You didn’t know how to respond, didn’t know how to let him in. So you looked away, your eyes drifting toward the floor.
But he didn’t let you turn from him. Instead, his other hand found its way to your cheek, lifting your face up to meet his. His touch was soft, tentative, like he was testing the waters, unsure if you’d pull away.
But you didn’t.
It was that moment. That moment where everything changed.
There was a flicker of something in his gaze: something raw, something darker than you’d ever seen. It made your heart race and made your breath catch in your throat. You could feel the heat of his body close to yours, the scent of him, the sound of his heartbeat matching your own. And in that space, it was like time slowed down. Everything faded away, and there was only him. Only Bucky.
And before you could even register what was happening, he closed the distance between you.
His lips brushed against yours, tentative at first, like he was waiting for you to pull away. But you didn’t. You leaned into him instead, your hands finding his chest, your fingers curling into the fabric of his shirt as you kissed him back.
It wasn’t soft. It wasn’t gentle. It was desperate, frantic. As if you both needed it. Needed the connection and the reassurance that you weren’t alone in this twisted, broken world. His lips pressed harder against yours, and your grip on him tightened, pulling him closer, deeper, until you could feel the thudding of his heart against your chest.
You both stopped thinking. There was no time for reason, no room for hesitation. There was just the moment. The kiss.
When you finally pulled away, your breath was shallow, your face flushed, and your heart raced as though you’d been running for miles. Bucky’s forehead rested against yours, his eyes closed, and he was breathing just as heavily as you were. His hand cupped your face, gently this time, like he was afraid you might shatter in his hands.
“I’ve wanted this for so long,” Bucky murmured, his voice rough, as though it hurt to hold back for so long.
You blinked, your pulse still racing. “Me too,” You whispered, your voice barely audible, but it was enough.
In that moment, everything made sense. All the confusion, the loneliness, the emptiness you’d both been carrying for so long, it was gone. In its place was something else. Something new. Something unspoken. And you realized then, with chilling clarity, that there was no going back.
You didn’t care about the Avengers anymore. You didn’t care about the missions, the enemies, nor the people you were supposed to protect. The only thing that mattered was Bucky. And now, him and you were tangled so deeply that there was no way out. No way back to who you used to be.
And that’s how it happened. Slowly. Quietly. You became his obsession and he became yours.
