You barely had a chance to take a seat before the interrogation began.

“Do you have gills?” Yelena asked, leaning forward like she was inspecting a specimen. “Or do they only show up when you're wet?”

You blinked. “Um—”

“Wait, hold on.” Ava cut in, arms crossed. “Do you eat people? Like, in a sexy way? Or like… teeth and blood?”

“Neither?”

Bob’s eyes lit up. “But hypothetically, if you were shipwrecked, would you rather lure sailors to their deaths or just vibe on a rock singing Adele?”

“I don’t—”

“Also,” Alexei boomed, squinting at you. “How do you have babies with tail? Is it like seahorses? Or salmon?”

“Why would it be like salmon?” Ava muttered.

“Maybe she lays eggs,” Bob said thoughtfully. “Do you lay eggs?”

You opened your mouth, then closed it again. This had to be a test. Some kind of extremely unorthodox hazing ritual.

“I’m sorry,” you finally managed. “Are these actual questions or did you all just watch The Little Mermaid before I got here?”

Walker, inexplicably sipping a protein shake at 8am, nodded solemnly. “So... do you explode if you drink salt water?”

You stared. “I'm from the ocean.”

“And what about chlorinated water,” he asked, completely serious.

Yelena snorted.

Before the next round of nonsense could begin, a voice cut through the chaos.

“Alright, that’s enough.”

You turned. Bucky stood in the doorway, arms crossed, expression unreadable. His eyes settled on you for a beat too long.

“Give her a second to breathe before you start asking about mating rituals.”

“Thank you,” you breathed.

He moved past the others, walking toward you with measured steps. You hadn’t realized how tense your shoulders were until he got close enough that the rest of the room seemed to dim around him.

“You okay?” he asked quietly.

You nodded, but couldn’t help the tiny smile tugging at your lips. “Do you ask all the new recruits about their reproductive methods, or just me?”

He huffed a quiet laugh. “Only the ones who are rumored to eat people.”

────────────────────────

A Few Days Later

You sat on the edge of the couch like a guest who wasn’t sure if they were invited or accidentally wandered in. Your posture was perfect, hands folded neatly in your lap, gaze fixed somewhere safe—like the TV that no one had turned on.

Yelena flopped down beside you with the grace of a feral cat. “You don’t talk much,” she observed bluntly. “Which is fine. Some of us overshare to make up for our emotional repression.”

“That’s just you,” Ava said from the kitchen, balancing a tray of chips and something that might’ve been experimental dip.

“Correct.”

Alexei hovered behind you, inexplicably trying to angle a photo of his dog toward your face. “This is Misha. He was trained to kill before he was housebroken. You would get along.”

“I’m… sure he’s lovely,” you replied politely, offering a tight smile.

Bob sat cross-legged on the floor like a camp counselor. “Okay, but seriously. Do you want anything to eat? We’ve got empanadas. And tofu stuff. And I think someone tried to make brownies.”

You shook your head. “Thank you. I’m not hungry.”

“No fish?” Walker smirked. “Or is it just... men on the menu?”

The room went dead quiet for half a second. Ava groaned.

“Really?” Yelena muttered.

“I’m a vegetarian,” you said quietly.

Walker blinked. “Wait, really?”

“Yes.”

“That’s even more terrifying,” Bob said thoughtfully. “You choose not to eat meat. Yet you still eat men. For sport, right?”

“I do not eat men.”

“Sure,” Ava said with a shrug. “But if you did, it’d be poetic justice. Like, ‘Oops, your ship tried to colonize my homeland, now you're lunch.’”

You gave a tight-lipped smile again, but the joke didn’t quite sit right. They didn’t notice the way your gaze dropped or how your fingers fidgeted slightly at the hem of your sleeve.

Except Bucky.

He leaned against the far wall, arms crossed, eyes on you in that quiet, unreadable way of his. Watching. Not judging. Just… observing. Carefully.

“You always like this?” Ava asked, circling to sit nearby. “Polite. Mysterious. Quiet. Like a goth librarian who also knows how to drown people with her mind?”

You hesitated. “I try not to make people uncomfortable.”

“You don’t,” Yelena said, popping a chip into her mouth. “We’re uncomfortable by default. It’s a trauma response.”

“You’re basically the least weird person in this room,” Bob added. “Which is suspicious in itself.”

That earned a small laugh from you—surprising even yourself. Heads turned, and you flushed faintly under the sudden attention.

“I’ll take that as a compliment,” you said.

It wasn’t much. But it was something. A sliver of trust cracked open just enough for light to slip through.

And across the room, Bucky eyes softened.

It had started with snacks and sarcasm. Someone had turned on a movie. Bob was quoting every line with annoying precision. Ava kept tossing popcorn into Walker’s protein shake. For a while, you had almost forgotten to be cautious.

Almost.

“Okay but seriously,” Yelena said, elbowing you gently, “you’ve got to let us see it sometime. The thing. With your voice.”

You hesitated. “It’s not something I do for fun.”

“But it’s, like... mind control, right?” Walker asked, overly casual. “Like Jedi mind tricks, but with falsetto?”

You glanced around. Ava watching with narrowed eyes, trying to read you. Bob leaned forward, too curious. Yelena still too close. Even Alexei had stopped mid-story. And Bucky—still across the room, still silent.

“It’s not mind control,” you said slowly. “It’s... influence.”

The air shifted.

“My voice can influence people. Not just emotion. Thought. Action.”

The joking stopped.

“And I can sense... intention. Urgency. Fear. Hunger. The things people hide.”

Then softly you added. “It’s not always... voluntary.”

There was something fragile in your voice then. Not a confession, but a warning.

Your gaze dropped to your hands, fingers curling in your lap. You could already feel it. The subtle recoil in their posture. Not loud, but enough. Enough for your pulse to tick faster, warning you.

“Damn,” John muttered. “So you just walk into a room and feel everyone’s business?”

“I try not to,” you replied, softly.

That landed harder than you meant it to.

The silence that followed was heavier than any you'd felt all day. Thick with the kind of unease you’d learned to recognize long before you joined this team. Not fear. Not rejection. Just... awareness. The realization that your power wasn’t theoretical anymore. It was here. With them. Listening.

You felt the wall go up in them before they even realized they were building it.

So you did what you always did. What you were best at.

You retreated.

Your shoulders folded in. Your body went still. Not dramatically. Not enough to cause a scene. Just... quieter. Smaller. Like someone sinking slowly beneath the surface of the sea.

No one said anything.

But from across the room, Bucky watched you carefully—jaw set, brow furrowed—not at you, but at the room. At the shift. At how fast they’d gone from teasing to tiptoeing.

And you?

You didn’t need to read anyone’s mind to feel how far away you suddenly were.

────────────────────────

Later That Night

The wind was soft out here. Almost warm, brushing past your bare arms with the gentleness of something that wasn’t trying to take anything from you. You sat curled on a narrow bench, knees pulled to your chest, chin resting lightly on them.

You hadn’t meant to be found. That was kind of the point.

So when the door behind you slid open, your heart sank just a little. Until you heard his footsteps. Quiet. Measured. Familiar now.

Bucky didn’t say anything at first. Just moved beside you slowly and sat down, leaving a respectful distance between you.

“I figured you might be out here,” he said, voice low. Like he didn’t want to scare you off.

You didn’t look at him. “Why?”

“You didn’t say anything.”

The corners of your mouth turned up, barely. “Didn’t know I was supposed to.”

“You’re not. Just... noticed.”

For a while, you both sat in silence, the kind that wasn’t awkward. Just... open. A space you didn’t have to fill.

“I didn’t mean to make them uncomfortable,” you said finally. Voice soft. Still watching the stars.

“You didn’t,” he said automatically.

You turned your head, just a little. “You felt it.”

He paused. “I felt them realizing they don’t understand you yet. That’s different.”

You shook your head slowly. “It’s okay. I’m used to it.”

His eyes flicked to you. You didn’t see the way they narrowed.

“I know what I am,” you continued. “People don’t have to say it. I can feel it. The moment it shifts. That little breath of fear when they realize I can reach inside their heads without asking. It’s not wrong. I am what they think I am.”

You looked at him then, just briefly. Enough for him to see the resignation. The calm acceptance that only comes from long practice.

“A monster,” you said quietly.

His jaw clenched, barely. You saw it, even if he tried to hide it.

“Don’t say that.”

“It’s true.”

“It’s not.” He turned toward you fully now. “You think you’re the only person on this team who’s scared of what they’ve done? What they’re capable of?”

You didn’t answer.

“You think any of us have clean hands?” His voice stayed even, but there was a tightness to it now. Not anger. Something closer to frustration. Or pained. “Ava’s killed for hire. Yelena was trained to be a weapon since she could walk. Walker…” He paused. “You saw the headlines.”

He let the silence hang for a beat.

“I spent seventy years hurting people with no choice. With no soul. If anyone here knows what it means to be used, to be feared—it’s me.”

You blinked. “That’s different.”

“Why?”

“Because you're human.”

He stared at you. Then, quietly, “And you're not?”

You didn’t respond.

The wind picked up. You turned your head back toward the night.

For a long moment, neither of you said anything.

Then, softly, “You scare them a little. Yeah. But not because you’re a monster.”

You glanced at him.

“They just don’t know you yet. And people fear what they don’t understand. But that doesn’t mean they won’t try.”

You looked down at your hands, where your fingers were laced tight together. Like you were holding something in.

“I don’t want to hurt anyone.”

“I know,” he said.

And you believed him.

Not because his words were kind, but because they were quiet. Steady. Because they didn’t ask anything of you.

Because he didn’t look away.

And for the first time since you joined this mess of a team, you didn’t feel like a weapon waiting to be triggered.

You just felt... seen.

────────────────────────

Abandoned Shipping Yard

It was supposed to be a clean extraction. In and out. Minimal resistance. Ava had scoped the perimeter, Yelena laid out the breach pattern, Walker was already ten paces ahead being Walker, and Bucky had given you a nod just before the comms went live.

You were ready. Or you thought you were.

The cold air clung to your skin as you moved through the corridor of rusted containers. You kept to the shadows, as always, listening more than speaking, watching more than acting. A quiet presence, there when needed—never more.

The first wave of hostiles came fast—mercs, jittery and underpaid. Nothing the team couldn’t handle. You barely had to use your voice.

But something changed.

Second floor. A new group. More organized. You didn’t see them until they’d already flanked Alexei. You reacted before you thought—instinct firing faster than strategy.

They raised weapons.

And you hummed.

Not loud. Not full. Just enough to stop them.

A sound low in your throat, rich with warning and pressure and pull. It rolled over the air like a tide, a siren note pitched directly into their nerves.

They froze.

Then they turned.

Not toward Alexei.

Toward each other.

Guns half-raised. Hands twitching.

Confusion swelled, slow and dangerous. One man dropped his rifle. Another started crying. A third turned to face you like he couldn’t remember why he was holding a weapon at all.

Then Walker’s voice shouted through comms: “What the hell was that?!”

A sharp click—a trigger cocked.

Bucky got there first.

He shoved the last merc down before he could swing his weapon back around, snapping a zip tie around his wrists with clinical precision.

“Clear!” Yelena called from above.

“Room’s secure,” Ava confirmed, quieter, voice tinged with something more cautious.

You stood in the center of the room, throat tight, breath short. The air still trembled faintly with the residue of your voice.

Everyone was looking at you.

No one said anything.

Until Walker.

“Was that you?” he asked, not angry—just stunned. Like he’d seen lightning strike too close. “What even—what was that?”

“I didn’t mean to—” you started, but your voice wavered.

“That wasn’t just noise. That was... influence, right? You turned them on each other?”

“No.” You swallowed. “I didn’t mean to. It just happened. They were going to shoot Alexei, I—”

“But it wasn’t controlled,” Walker said sharply. Not cruel, just assessing. Calculating risk. “What if they’d turned on us?”

That stung. More than it should have.

“I wouldn’t,” you whispered. “I didn’t mean to—”

“She said it was involuntary,” Bucky cut in, stepping forward. His voice didn’t rise, but it carried weight. “She stopped them. That’s what matters.”

“She also almost made a guy kill himself,” Walker muttered.

“She saved Alexei,” Bucky said firmly, turning toward the others. “We’ve all lost control before. Don’t pretend we haven’t.”

You stood silent, heart pounding, the aftermath of your own power still vibrating under your skin. The others started moving again—resetting, clearing the area, checking gear. But they gave you space now.

Too much space.

You barely heard the rest of the debrief. Your voice was gone, locked behind clenched teeth. Guilt wrapped around your chest like a vice.

You walked ahead in silence.

No one stopped you.

────────────────────────

You hadn’t even taken off your boots. You sat on the floor, back against the wall, arms wrapped tightly around your knees like they might keep you from slipping any further into yourself.

The door creaked open softly.

You didn’t look up.

But you knew the sound of his steps.

“Thought I’d find you here,” Bucky said gently.

You didn’t respond.

He came closer but didn’t sit. Just leaned against the opposite wall, arms crossed loosely. Watching. Waiting.

“I lost control,” you said after a long moment. “They’re right to be wary.”

“They’re wrong,” he said simply.

“You didn’t see their faces.”

“I saw yours.”

You glanced up, surprised.

“You looked like you were trying to tear yourself in half,” he said. “Because you cared more about hurting them than saving yourself.”

You looked away again.

“They don’t understand what it feels like,” you said quietly. “To have something inside you that people fear. That you can’t always lock down. That might one day hurt someone—even if you don’t want it to.”

His expression shifted. Pain, recognition, something deeper.

“Yeah,” he said. “I do.”

You looked at him then. Really looked.

The softness in his face, the tension in his shoulders—he knew. He knew.

And still, he was here.

Not afraid. Not flinching. Just... here.

You exhaled shakily.

“I think I made a mistake joining this team.”

“No,” he said. “You didn’t.”

“How do you know?”

“Because I’ve been watching you,” he admitted. “And not because I’m waiting for you to snap. I watch because I see you trying. Every damn day. Even when they don’t notice.”

Your throat tightened.

“You don’t scare me,” he added. “None of this does. You do more to hold yourself back than most of us ever have to.”

Silence.

Then, softly: “You belong here. Even if it takes them time to see it.”

────────────────────────

The Next Night

Bucky wasn’t looking for you.

That’s what he told himself.

He told himself he was going for a walk. That his muscles ached. That the silence in his room was too sharp around the edges tonight.

But when he passed the door to the training pool and saw it slightly ajar, lights off, humid air curling into the hallway like a whisper—he knew.

Of course it was you.

He stepped inside quietly, the heavy door hissing shut behind him. The sound echoed across the still water.

“Hey,” he called out softly, scanning the dark. “You left the lights off.”

He moved toward the control panel instinctively, fingers brushing the switch.

“Don’t,” came your voice.

Not a shout. Not even stern. Just quiet. Low.

Carried like a ripple across the water, echoing from somewhere deep in the pool.

He froze.

“…You okay?” he asked, softer now.

A pause.

Then, “Yes.”

But there was something in the way you said it—like you were holding your breath inside the word.

The pool was a long, Olympic cut of black glass. He could barely make out your shape beneath the surface—a flicker of motion in the far end, a slow shift of shadow.

“You’re in the water.”

“Yes.”

The silence stretched again, heavy but not uncomfortable. He stepped forward, letting the heat of the pool air wrap around him.

“I thought maybe you’d gone,” he admitted. “After yesterday.”

There was a sound, something like a soft splash. A flick of fin, maybe. Movement, not retreat.

“No,” you said. “I just needed to be… this. For a while.”

He squinted toward you, his eyes adjusting to the dark. It took a moment, but then he saw it—just barely. The curve of your back breaking the surface. The subtle gleam of something slick and scaled beneath the low ambient light.

He didn’t speak. Didn’t stare. Just stayed still.

You exhaled slowly, the sound barely above the waterline. “I’m not hiding.”

“I didn’t say you were.”

“I just don't want to be seen like this. Not… yet.”

He nodded, even though you probably couldn’t see it. “Alright. Then I won’t look.”

And to his credit, he didn’t.

He turned away slightly, gave you space, let you move without watching. But he still stayed. Because you hadn’t told him to go.

Because, maybe, you wanted someone to stay.

“I’m not human the way you are,” you said after a while. “Not just physically. Sometimes I feel like I’m wearing skin that doesn’t belong to me.”

He breathed in slow. “I know that feeling.”

“Do you?” you asked, not unkindly. Just tired.

Bucky shifted his weight. “I’ve worn a lot of masks. But yeah. There are days where I look in the mirror and don’t see someone who belongs anywhere.”

The water rippled quietly.

“Then you understand why I needed to be in the dark tonight.”

He nodded. “Yeah.”

A pause.

“You ever wish you could just… stay like that?” he asked gently. “Who you are in here. Not the version you have to show everyone else?”

You didn’t answer right away.

Then, “Sometimes I think the version they see is the monster. And this—the water, the dark, the scales—that this is the real me.”

“And is she the monster?”

“No.”

Then you added, softer, “She’s worse.“

The words sank like stones.

You waited for him to back away. To excuse himself. To do what most people did when they saw behind the illusion.

But he didn’t.

“You’re not a monster,” he said, steady as stone. “Not in any form.”

You let out a breath—half bitter, half broken. “You should be afraid of me.”

“I’m not.”

“You should be.” A sharp breath. “Especially you. After what you’ve been through. After what it’s like to have your mind twisted, your will taken—I could do that to you. Without even trying.”

Silence.

You expected him to leave. You preferred him to leave.

Then a soft rustle.

You heard it before you saw it—fabric sliding off. The quiet thud of boots meeting concrete. A belt unhooking. Then another sound: the shift of weight, the hiss of disturbed water.

Your head turned sharply in the dark. “What are you doing?”

Bucky’s voice came low and calm. “Showing you I’m not afraid.”

His bare feet met the water first, then his legs. He stepped slowly into the pool, each movement careful, deliberate—like he was approaching a wounded animal. Like he knew you might vanish if he moved too fast.

You froze.

The lights stayed off.

The water rippled gently around him, catching faint echoes of motion from where you were submerged.

“You can’t even see me,” you said.

“I don’t need to.”

Your voice trembled. “You don’t know what I look like like this.”

“I know what I feel,” he said. “I know it’s you.”

He moved further in, the water reaching his ribs, his breath slow, steady.

You stared across the dark, at the shape of him—a silhouette against nothing. Vulnerable. Unarmed. Open.

You whispered, “Why?”

He paused, standing still in the middle of the water.

“Because you’ve spent your whole life trying not to scare people,” he said. “Trying to keep yourself small, quiet, contained. And no one’s ever just... let you be.”

You blinked.

Something deep inside you shifted.

“I’ve been used too,” he said softly. “Controlled. Hurt. Turned into something I didn’t recognize. And I’m still here. Still fighting to believe I’m not what they made me.”

The ripples between you both softened. Fewer waves. Less space.

You whispered, “You’re not.”

“Neither are you.”

For the first time in a long time, you felt like you could breathe.

Not in the way you did above water—but in the way that didn’t hurt.

“You shouldn’t trust me this much,” you said, a final warning. One last barrier.

“Maybe,” he said quietly. “But I do”

The water between you held its breath.

You didn’t move at first—didn’t trust the trembling in your limbs or the sharp edge of your pulse. But Bucky stood still, waist-deep, facing the other side of the pool, like he wasn’t waiting for danger—just for you.

So you moved.

Slowly. Silently. The water embraced your form the way it always had—your real shape, the one you kept hidden beneath flesh and clothes and fear. You glided like breath, like tide, like instinct. Your tail made no sound. Your scales caught no light. You were the shadow beneath the surface, and he didn’t flinch.

Not even when you came close.

Close enough to touch.

You hovered at his back, watching the curve of his spine rise and fall with every breath. Water clung to his skin, catching faint glints of motion—your motion—as you lifted a hand above the surface.

And touched him.

His shoulders tensed at first, just barely, but he didn’t pull away.

Your fingers were cool against his skin—webbed, slick, foreign. The pads of them brushed along the ridge of his shoulder blade, then down the line of his arm.

Still, he didn’t turn.

So you did it again.

This time, both hands—light and deliberate—placed just above his hips, fingertips resting at the base of his spine, gently urging.

He let out a slow breath.

And turned.

The water shifted as he faced you.

He still couldn’t see all of you—darkness and depth obscured your form—but he could feel you there. Close. Solid. Real.

His hands came to your waist, cautious, reverent. His thumbs brushed faint ridges along your sides—faint scales you hadn’t hidden, soft flesh beneath them. He could feel the texture of you, alien and familiar all at once.

You let him look.

Not completely. Not yet.

But enough.

You tilted your head up, and he bent just slightly toward you. His face a breath away, eyes searching yours in the dark.

“I see you,” he whispered.

And he did.

Not a siren. Not a monster. Not an aberration.

Just you.

The water lapped quietly around you, the two of you suspended in the dark.

Bucky was so close now. Close enough for the heat of his body to ghost across your skin despite the coolness of the water. Close enough that the contrast between you—his warmth, your chill—felt like static between touching wires.

He looked at you then, fully. His eyes locked on yours, no hesitation. Just slow awe.

You saw the flicker of realization behind his gaze.

Your eyes—icy and deep, nearly luminescent in the dark—weren’t human anymore. The pupils too sharp, the color too unnatural. You didn’t try to hide it.

And still, he whispered, breath brushing your mouth,

“I’m not afraid of you.”

Your lips parted, not to speak, but just to feel that warmth.

Then he leaned in—deliberate, drawn, inevitable—and kissed you.

The first touch was slow, hesitant only in reverence, like he was afraid of breaking something sacred. His lips were warm—so warm—pressing softly against yours, testing.

You didn’t hesitate.

You kissed him back, and the pull was instant. A current dragging you both under.

His hands rose, one settling against the back of your neck, the other at your waist, anchoring you to him. You opened your mouth against his—slowly—and his tongue slipped inside with a soft groan that vibrated low in his throat. You tasted him: salt, metal, heat, something earthy and real.

He tasted you: cool and mineral, like sea-salt and secrets, ancient and raw.

His tongue tangled with yours in deliberate strokes, slow and deep. It wasn’t frantic. It was exploration, mouth against mouth, breath mingling, like he was learning you piece by piece.

Then he felt them.

The faint edge of your fangs—barely exposed as your body stirred with instinct and desire.

He didn’t pull away.

He kissed you harder.

And you let him.

Your webbed fingers curled into his hair, claws grazing his scalp just enough to make him shiver. His hand slipped lower, across the slick curve of your back, dragging you flush against him in the water. Your tail brushed his legs—he felt the ripple of it, powerful and sinuous—and instead of flinching, he leaned into it.

He deepened the kiss with a quiet groan, tilting your head just enough to taste more of you, to chase the sharp edge of your teeth and the soft gasp you gave him when he sucked on your bottom lip.

He wanted more. You wanted.

But the kiss said it all: this wasn’t hunger.

It was surrender.

And when he pulled back—only slightly, his forehead resting against yours, both of you panting, breath fogging between mouths—his voice dropped again, rough and reverent.

“You’re not a monster.”

You trembled in his arms, not from cold.

And for the first time, you let someone hold you without fear of what they’d find in the dark.

The kisses evolved—mouths moving in rhythm, breathless and hungry, like they’d been holding back for far too long. The water around you rippled with every shift of your bodies, your bare skin slick against his, every nerve alive.

Bucky’s hands slid lower, smoothing over the firm plane of your back where slick, textured scales had shimmered moments ago. But now—he felt it.

They were fading.

His lips broke from yours just enough to murmur, breath hitched, “You’re changing…”

Your forehead pressed to his as your hands threaded through his wet hair. “I can’t stop it,” you whispered. “When I feel—”

He kissed you again, cutting the words off with a gentleness that said you don’t have to explain.

The transformation was slow, intimate.

You felt it first in your hands—your fingers unwebbing, reshaping. Human again. Your claws softened, becoming skin. You ran them down his chest, gasping softly at the warmth, the roughness of him against the new smoothness of you.

Bucky’s hands wrapped around your waist as you shifted again, the powerful muscles of your tail twitching, tensing—then separating.

Legs.

Human.

Bare.

You wrapped them around his hips instinctively, pulling him closer, water lapping between your bodies, heat blooming between where his skin met yours.

His breath caught, hard, sharp.

You were soft and solid and real in his arms, human now but still you—something wild and full of want beneath the surface. He kissed down your jaw, tasting salt and skin and a thrill he hadn’t felt in years.

His voice, low and rough, ghosted along your throat: “You don’t have to be afraid.”

You shivered in his hold, lips brushing his ear as you whispered back, “I’m not.”

And for once, you weren’t.

Not of what he’d think. Not of what you were. Not even of what you wanted.

Just the sound of your shared breath, the gentle churn of the water, the beat of two hearts finally in rhythm.

Your legs wrapped tighter around his waist as he held you against him, his hands roaming—slow, reverent, learning every curve and shape as if memorizing what it meant to have you.

Not to claim.

But to be allowed.

The warmth of him bled into you, his mouth trailing over the column of your throat, lips parting around your skin as he kissed lower—slowly, like he wanted to taste every shiver.

Your fingers dug into his shoulders as his mouth returned to yours—hungrier this time. Tongues sliding together with unspoken urgency. He groaned into you, low and rough, when you rolled your hips into him beneath the water.

The sound you made—half gasp, half moan—hit him like a shot to the spine.

His hands cupped the back of your thighs, holding you up, keeping you close, guiding your body so you fit around him perfectly. The heat between you sharpened, pressed tight through soaked fabric and wet skin, every movement stoking something deeper.

There was nothing frantic.

Only build.

Only the slow, sacred pull of yes.

The kiss deepened until there was no air between you. His chest pressed to yours, heat meeting the coolness of your skin, fingers curling along your ribs, tracing the path where scales had once been.

You tilted your head back as he kissed his way down—jaw, neck, collarbone—tongue flicking against the hollow of your throat. Each touch lit up something low in your belly, and when you whispered his name, he froze just long enough to look at you.

Eyes dark, lips parted, hands still reverent.

“Are you sure?” he asked, voice hoarse, wet strands of hair clinging to his brow.

You nodded, breathless. “Yes.”

Bucky’s mouth returned to yours with hunger barely tempered now, his kiss pulling sounds from your throat you didn’t know you could make—not songs, not power. Just want.

He guided you back through the water, hands steady at your waist, until your spine met the edge of the pool wall. The tile was cool against your back; he was warm and solid against your front.

His fingers brushed along the curve of your ribs, then up—slowly—tracing the faint shimmer where scales had retreated. He explored each new inch of you with careful reverence, like he was learning you with his hands, like every discovery mattered.

Your breath hitched as he slid one palm beneath the water, low across your hip, then between your thighs—fingers ghosting over the softest part of you with a touch so achingly gentle you shivered.

He swallowed the moan that left your mouth as his other hand found your jaw, tilting your face up so he could kiss you again—deeper now, tongue claiming, teeth grazing your lip.

You gasped, fingers curling around the back of his neck as your legs tightened around his hips, urging him closer.

He groaned, low and wrecked, as he pressed his body into yours fully—his arousal hard against you, his mouth dragging kisses down your throat as you arched into him.

“God, you feel like…” he murmured, unfinished, overwhelmed, pressing his forehead against yours.

Your hand found his chest, feeling the steady, pounding rhythm beneath the scars. “I feel like what?”

He looked at you like you were unreal. “Like something I’ve never deserved. But I’m not letting go.”

He reached down again, guiding himself into you with aching care.

When he pressed into you—slow, stretching, deep—your mouth parted in a soundless gasp, nails sinking into his back as your body opened for him.

The sensation was molten. Your body slick and ready, still half-wrapped in water, and every movement felt amplified—rippled and weightless, like being made and unmade in slow motion.

He held still inside you for a beat—his breath stalling, eyes locked on yours.

“You okay?” he whispered, thumb brushing your cheek.

You nodded, voice caught in your throat. “Don’t stop.”

So he moved.

Rhythmic. Deep. Rolling his hips into you with intense precision, like he wanted every thrust to be a memory etched into your bones.

You clung to him as you rocked together, lips never far, gasps exchanged like prayer. The water splashed gently around you with every movement, hiding and revealing, sheltering and exposing.

And when you came apart in his arms—body shaking, breath hitching, fingers tangled in his hair—he followed seconds after, groaning into your skin as he buried himself in you one last time.

Afterward, he didn’t let go.

He just held you, still wrapped in warmth and water, as if grounding himself in the shape of you—your real form, your chosen form.

And you stayed there, arms around him, mind quiet for the first time in days.

────────────────────────

You lay together outside the pool, still dripping, the tiled floor beneath you warmed by residual heat from the water and each other.

Bucky’s body was solid and relaxed beneath yours, your head resting on his chest, your arm draped across his ribs. His breathing was slow now, steady, one hand lazily tracing your back—his fingers brushing the faint outlines of where your scales had shimmered.

He didn’t speak for a while. Just let his fingers explore you softly, as if mapping something sacred.

Then, voice low, “So… the other you. The form in the water. Is that the real you?”

You didn’t answer right away.

Your breath pushed gently against his skin, your eyes half-lidded with calm.

Then softly, “Both are the real me.”

He didn’t move, but you felt the weight of his silence.

You lifted your head slightly, just enough to brush your lips against his—light, unhurried, a kiss not driven by need but by quiet affection.

A moment passed before you added, “I’m half-human. Half-siren.”

His eyes opened, and he tilted his head to meet your gaze, brows furrowed—curious, but not skeptical.

You sighed, a faint smile ghosting your lips. “Tale as old as time. Sailor meets siren. Siren gets curious. Doesn’t immediately murder him.”

That made him huff a quiet breath against your temple.

“Sometimes… they mate. Rarely. Just to understand. Or because something stirs in them they don’t expect. The sailors rarely survive the interaction. Then they return to the sea.”

His fingers paused at your spine.

You shifted your weight slightly, eyes locked on his, and said quieter still:

“This time, the siren left with a baby.”

His breath caught, just barely.

You looked down.

“And that baby got left behind on land. Half-breed. Too human for the ocean, too strange for the shore.”

He said nothing.

But his hand moved again—this time higher, threading through your hair, cupping the back of your head gently as if trying to hold that pain, that truth, without crowding it.

You exhaled slowly, resting your forehead against his collarbone.

“A monster on land. An abomination in the sea.”

The words hung between you like steam, curling and vanishing before they hit the air.

Bucky didn’t try to correct you. Didn’t rush to wrap those words in comfort. He just moved—his hand smoothing up your back, across your hair, anchoring you to his chest. Holding you like it was the only thing he knew how to do.

His hand never left you.

Now, it moved with a new purpose—his touch slower, more intentional, tracing the skin between your shoulder blades.

You stiffened slightly.

He’d found them.

The scars.

Faint, old, but still jagged—slashing diagonally across your back in places that seemed more symbolic than accidental. He ran a thumb along the longest one, slow and careful.

“They match,” he murmured.

Your brow furrowed. “What?”

“Your claws,” he said. “From before. In the pool. The shape of them.” He traced another line. “These look like what they’d leave.”

You were quiet for a long moment.

Then you whispered, “They did.”

“You mean—?”

“The sirens,” you said softly.

He froze. “Jesus.”

You pushed your face gently against his shoulder, hiding from the look you couldn’t bear to see on his face—pity, horror, heartbreak, you didn’t know which would be worse.

“I didn’t belong here,” you murmured. “On land. Never really fit. So I thought—maybe the ocean would feel like home. Maybe they would understand.”

His hand stilled on your back.

You swallowed. “They didn’t.”

You pulled in a shaking breath, voice tight but steady. “They said I was soft. Weak. That I smelled too human. Felt too much. That I’d taint their species if I stayed.”

A beat.

“They tried to tear the human out of me.”

Bucky closed his eyes. His jaw tensed beneath your hand where it rested on his chest.

You whispered, almost bitterly now, “All the myths are true. They are monsters. They don’t love. They don’t feel. They don’t keep anything they can’t control.”

Silence.

Bucky’s fingers paused again, still tracing the old scars like they were something sacred. “You survived them,” he said quietly. “That says more about you than them.”

Your breath hitched, then came slow and shallow.

“I didn’t just survive them,” you murmured. “I tried to be like them.”

He stilled.

“I thought if I let go of everything human in me, they’d let me stay. If I stopped feeling… stopped flinching when they hunted. When they—”

You stopped, your throat tightening.

Bucky’s eyes were open now, watching you with more than concern. With something like dread.

“I tried,” you said, barely above a whisper. “To become what they were. To be unfeeling. A real monster.”

Your fingers curled slightly against his chest. “I even did it. Their way. Took ships off course with my voice. Lured them close. And I fed.”

His hand faltered.

“I ate humans,” you said, the words fractured, sharp. “So they’d accept me.”

Silence.

The worst kind.

Bucky didn’t move. He didn’t breathe, but you felt his body tense underneath you—hurt, not at you, but for you.

You turned your face further into his shoulder, shame crawling up your spine like ice.

“But it never worked,” you whispered. “I was still too soft. I felt everything. Even when I tried to bury it.”

His arms wrapped tighter around you—gently, but with purpose.

“I couldn’t keep it down,” you continued. “The guilt. The screaming. The way they laughed at me for choking on blood.”

Your voice cracked. “Meat makes me sick now. Just the smell of it.”

He breathed then, long and broken.

You could feel his heartbeat under your cheek. Steady. Solid. And somehow still here.

The silence between you became thick. Not with judgment, but with something worse—your own shame.

You whispered, barely audible, “I became something I hate. I wanted so badly to stop being an outcast, I turned myself into a real monster. And they still didn’t want me.”

You closed your eyes. “They didn’t need to kill me. I did that myself.”

Bucky exhaled slowly, his hand sliding up from your back to cup the back of your head again. He didn’t say it’s okay. He didn’t say you’re forgiven. He didn’t try to rewrite your past.

He just held you.

Because there are wounds too deep for words.

Because you had already condemned yourself, and he knew the last thing you needed was someone else trying to absolve what you hadn’t even survived emotionally.

Still, his voice reached you, low and rough and real,

“I hope someday you'll understand that you were never the monster in that story.”

You didn’t respond. You didn’t believe it. But you didn’t pull away, either.

And for now—that meant something.
