on command.

this is the first story from my 707 followers' milestone event 💖

Pairing: Avenger!Bucky x Medic!Reader (female)

Summary: It started with a question you didn’t realize sounded filthy: “Can you come on command?” Bucky thought you were teasing. But you were just too clinical to know better. And now? He’s going to show you exactly what happens when curiosity goes too far.

The med-bay smelled like antiseptic and fresh laundry—too clean for a room that had known so much blood. It was a Sunday evening, quiet and uneventful, the kind of shift where silence hummed against your ears and your thoughts wandered deeper than you intended. The kind of boredom that stretched into your ribs.

Until you heard the heavy thud of combat boots echo down the hallway.

You looked up from your tablet. He walked in with a presence that made the sterile air feel charged.

James Buchanan Barnes

Unit: Thunderbolts

Registry: Alpha-01

Notes: Vibranium prosthesis (left arm). Serum-enhanced physiology. Prior Hydra experimentation flagged in psychological history.

His combat shirt hung from one shoulder, blood soaked into the seams. His torso was bare—bruised, sweating, smeared with dried streaks of red. Deep brown hair fell in damp strands against his temples, jaw tight, body moving like something made to endure.

“Didn’t know we had new faces,” he said, voice gravel-rough as he eased himself down onto the med-bed. “Nice change.”

You nodded once and pulled on gloves. “Yes. I started this week.”

He dropped the shirt beside him, settling in like the cot was his personal recliner. The tone in his voice had suggested ease, maybe even a joke, but you didn’t react. You weren’t always sure when people were being sarcastic.

Especially not him.

You retrieved gauze, saline, antiseptic. You were focused on the wound low across his abdomen—a shallow blade graze, already clotting along the edge. As you cleaned around it, you recalled a conversation from earlier that week. Your first night shift had been filled with stories, warnings, casual gossip from the senior medics. They spoke about the team like they were walking myths. And Bucky Barnes, in particular, had been the centerpiece of several of those stories.

He can do anything if you tell him to, someone had said. Hydra programming, you know? Sit, kneel, come—just say it.

You hadn’t laughed. You’d written it down. Because you didn’t know it was a joke.

Now, he sat bare-chested in front of you, quiet, unmoving, skin warm beneath your gloved hands as you pressed sterile pads to the wound.

The question formed itself before you realized it was inappropriate.

You spoke plainly, genuinely. “I was wondering—can you get hard and ejaculate on command?”

The silence that followed was total. Not a pause. Not surprise.

It was a shift.

You didn’t notice it right away, too focused on folding gauze precisely, until the weight of his gaze pulled you back to the moment.

When you looked up, his entire body had stilled.

His eyes were on you. Unmoving. Brow low, mouth parted just slightly, as if he were still computing the words. The faint line between his brows deepened.

“Come again?” he asked, but his voice wasn’t casual. It wasn’t flirtatious either. It was something closer to caution.

You met his stare. “I asked if you’re able to achieve erection and reach orgasm on command. Based on what the other officers implied regarding your conditioning.”

He blinked once. Very slowly.

Your tone hadn’t faltered. You weren’t embarrassed. You were just curious—curious the same way you’d asked someone last week if the Hulk’s resting heart rate really was thirty-five BPM.

Bucky leaned back slightly, eyes scanning you like he was waiting for the punchline. When it didn’t come, his jaw worked, muscle flexing once under stubble.

Then he stood.

Not abruptly. But with enough weight behind the motion that you instinctively stepped back. The tray clinked behind you.

He stepped closer, enough that you felt the heat coming off his skin. Still watching you. Still trying to process.

“You’re seriously asking me that?” he said, quieter now. “Like, you’re not messing with me.”

“No,” you answered plainly. “I just wanted to understand the scope of the conditioning. Neurological control of physiological functions isn’t unheard of.”

He dragged a hand down his face. Let out a long breath through his nose. You saw the flicker in his expression—somewhere between disbelief and… something else.

“You really don’t realize how that sounded, do you.”

You tilted your head. “Should I?”

He huffed a soft, disbelieving laugh, almost under his breath.

Then he moved forward again—closer. Close enough that your hip bumped the counter edge.

“Are you asking because you want to know,” he said slowly, gaze dragging down your face, “or because you want to see?”

You stared back at him, unflinching. The intensity in his eyes didn’t register as threatening to you—just confusing. Your fingers curled slightly at your sides, still gloved. Still sterile. Still in the mindset of diagnostics and assessments, not flirtation. You weren’t sure what he meant by see, but the phrasing seemed to demand clarity.

So you gave it.

“I want to know,” you said plainly, meeting his eyes. “But if visual confirmation is possible, then yes—seeing would be helpful.”

His face didn’t move at first.

Not a blink. Not a breath.

Then his eyebrows lifted just a fraction—just enough to break the tension—but his mouth stayed parted like he’d lost his words somewhere between inhale and exhale.

You watched him, calm as ever. Not realizing that what you just said, to him, sounded like you were practically asking to watch him jerk off in the middle of med-bay.

His eyes narrowed slightly, still scanning you for a punchline. When there was none, something shifted. Not in you. In him.

Because that’s when it hit him—hard.

You weren’t fucking around.

You weren’t teasing. You weren’t flirting. You weren’t setting him up for some kind of HR trap. You were genuinely trying to understand the technical boundaries of Hydra’s physiological conditioning, like you were running through a checklist for your own notes.

He exhaled once through his nose and ran his palm over his jaw.

“Jesus Christ,” he muttered, half to himself. His gaze flicked to the side, like he needed to look anywhere but directly at you for a moment.

You could see it happening—the calculation behind his eyes. He was deciding whether or not to walk away. Whether to laugh. Whether to report this. But then something else moved through him, too—curiosity. You recognized the signs: pupils shifting slightly, breath shallower. He wasn’t sure either.

“I mean,” he said at last, voice rough, uncertain. “I’ve never… actually tried that. Not like—deliberately.”

You tilted your head slightly. “Would you be open to attempting it?”

His mouth parted again, like he wanted to respond but couldn’t decide which direction to take it. You sensed hesitation and tried to reassure him in the only way you knew how: by defaulting to protocol.

“If you’d prefer this be off-record,” you added, “we can skip the video documentation. I’ll log it manually.”

That did it.

His jaw dropped just a fraction further as he let out a breathless, incredulous noise. It wasn’t quite a laugh—it was something between disbelief and amusement, and it landed heavy in the air between you.

He looked back at you like you were some rare, alien creature. And maybe you were.

You hadn’t moved. You weren’t flustered. You weren’t seducing him. You were just… waiting. Like this was any other medical procedure.

Bucky dragged a hand through his hair, clearly still processing. Then his eyes returned to yours.

“You really wanna see if I can do that,” he said. It wasn’t a question. More like a final check. Like he needed to hear it in your voice one last time before he crossed the line.

“Yes,” you said simply. “For observation purposes.”

There was a long, still beat.

Then his stance shifted.

Something subtle in the way his feet planted, in the slow curl of his fingers at his side, in the way his shoulders rolled back with quiet intent. He wasn’t leaning anymore—he was centered now. Present. Watching you as something darker flickered behind his expression. Something curious. Something charged.

He nodded once. Low. Controlled.

“All right,” he said roughly, voice dipping just a bit lower than before. “Try me.”

—

You gave a short nod, already reaching back toward the tablet on the metal tray behind you, fingertips hovering to wake the screen. The chance to collect a new data point—something none of the other medics had dared ask for—was unexpectedly thrilling.

But the rustle of fabric behind you pulled your focus.

Bucky had stepped away from you again, his heavy boots padding quietly as he moved back toward the med-bed. Except this time, his fingers were already at his waistband.

You froze halfway between the tray and your chair.

He turned slightly toward you, eyes locked onto yours as his thumb worked open the button of his tactical pants. The zipper followed with a quiet rasp, slow and deliberate. He wasn’t speaking. Just watching.

And only then, only then, did your brain finally process the image forming in front of you.

His pants loosened around his hips, hung low now—unzipped and open just enough for you to see the black band of his briefs and the defined lines of his lower abdomen. The cut you’d just cleaned stretched faintly when he moved, muscles flexing subtly under the skin. His cock was still covered, but the shape of it—resting heavy against the fabric, shifting slightly as he adjusted—was impossible to miss. Still soft. Still untouched. But undeniably there. And Bucky wasn’t breaking eye contact.

Something shifted in your chest—an odd tightness you weren’t familiar with. A spike in heart rate. Not fear. Just sudden, confusing awareness. Your lips parted slightly, and your fingers fell away from the tablet screen.

Bucky let out a quiet breath. Not a laugh, not quite. A huff, amused and something darker beneath it.

“You’re realizing how bad everything looks now, huh?” he said, and his tone was different—still low, still calm, but tinged with heat. A crooked smirk played at the corner of his mouth. “Starting to piece it together?”

You didn’t answer. You couldn’t—not yet.

Because the tension in the air had shifted again. The weight of it wasn’t theoretical anymore. It was physical. Heavy. Warm. Centered on the space between you and the man now standing with his pants undone, cock barely covered, staring at you like this was still part of your little experiment.

You swallowed. Just once.

“I can stop,” he added, arching a brow. “But if you’re gonna ask me to do this… I need you to say it.”

“Say it?” you echoed.

He nodded, the line of his jaw tight, like something about this had challenged him in a way he wasn’t used to. “Yeah. The command. Give it. Let’s see if it works.”

You blinked, heartbeat tapping quick in your throat. Your gloves felt suddenly too tight.

It was for science.

Wasn’t it?

Except… now you were staring at the shape of a man’s cock through his briefs. At the subtle way it shifted behind fabric. At how he just stood there, open like a test subject, waiting for you to initiate the next step.

And suddenly, your carefully ordered brain started… glitching.

This wasn’t how it was supposed to look. It wasn’t supposed to feel like this—warm skin, eye contact, unspoken tension stretching tight across the space between you like a surgical suture about to snap.

You tried to stay focused. Tried to categorize what was happening as neuromuscular stimulus, externally initiated. That’s all. But the words slipped out of your mouth before you could repackage them more… appropriately.

“What kind of command should I say?”

Bucky’s brow arched. He shrugged one shoulder, still loose, still watching you like you were the show now. “Anything,” he said, voice smooth but quiet. “Try whatever comes naturally.”

Your brain immediately clicked into gear, cataloging possibilities, filtering for language precision. He’d said command. Singular. Direct.

“Get hard,” you said.

Bucky blinked once, slowly. “You might need to be more specific,” he murmured, the corner of his mouth twitching. “There’s a lotta things in here that can get hard. Floors. Plastics. Steel.”

You paused. Blinked again. Fair. Logical.

Your eyes dropped to the bulge at his front, the soft outline of his cock resting slightly to the left beneath dark cotton.

So you recalibrated. Clarified.

Your voice was steady when you said it:

“I command the cock of Bucky Barnes to get hard.”

The silence that followed wasn’t quiet. It was crackling. Electric.

And then—it worked.

You watched, frozen, as the shape beneath his briefs shifted. Thickened. From a resting weight to something firmer. Fuller. The fabric tightened around him as the shaft pressed upward and outward, no longer soft, no longer passive. He twitched once—just enough to catch your eye—and then kept swelling.

Your lips parted. You didn’t move.

That wasn’t supposed to happen.

It couldn’t happen.

But it had.

And Bucky… Bucky exhaled something between a scoff and a groan, and tipped his head slightly back like he couldn’t believe it either. When he looked at you again, his pupils had darkened, narrowed, and the curve of his lips had turned into something far less amused and far more interested.

“You’re kidding me,” he murmured, shaking his head. “You actually meant that.”

You nodded once, slowly, as your eyes locked onto the now very-obvious bulge straining his briefs.

He smirked, but there was a heat beneath it now—a flicker of something dangerous. His voice dropped a notch deeper.

“More.”

“What?”

“Give me another command,” he said. “Anything. Let’s test your theory.”

You hesitated. A beat too long. Then your eyes dropped again, tracking the shape beneath the black fabric. Your breath hitched—quiet, but noticeable to both of you. Your gloved hand curled reflexively at your side.

You bit your lip.

And then, softly, clinically—

“Twitch for me.”

And it did.

Just slightly. A small, visible movement under fabric. But enough.

A pulse. A response. An involuntary contraction of arousal-based musculature.

Your throat went dry.

A chill spidered down your spine, despite the warmth flooding your neck. Your mind scrambled to reframe this—to maintain control—but this no longer felt like controlled scientific inquiry. This was crossing into something else. Something biological. Something reproductive.

This wasn’t a training module anymore.

This was a live demonstration.

And you were the sole witness.

—

Bucky’s fingers curled under the waistband of his briefs.

He held your stare for a moment—something unspoken hanging in the air between you—and then he pulled them down.

Not rushed. Not coy. Just practical. Like it was necessary for the demonstration.

“You wanna learn properly, right?” he said. His voice was smooth, but edged. “Gotta see it bare if you want the full data.”

You didn’t answer. Couldn’t.

Because your breath caught the moment it came into view.

You choked—literally—on your own saliva.

Half-hard, and already thick. Heavy. You could see the potential of it, the way the veins curved beneath flushed skin, the slight upward tilt even in its semi state. It looked obscene without even being fully erect yet, and you couldn’t stop your eyes from tracing it, from measuring it mentally like you were still running diagnostics.

But you weren’t anymore. You knew that now.

Bucky saw your stare, the way your eyes had locked there like you forgot how to blink. His voice dropped, barely audible over the thick hum of your pulse.

“Give me another command.”

Something in your body responded before your brain did. Your feet shifted—one step forward. Then another. And another. Four in total. Just enough to bring you closer. Close enough that you didn’t have to squint to see the twitch of him. The weight of it.

Your gaze finally broke from his cock and lifted—slow, dazed—until you met his eyes again. There was something in them now. Not confusion. Not amusement.

Permission.

“Stroke it for me,” you said, voice quieter than before. Not clinical. Not innocent. Just… real.

And that was the moment the game changed.

Bucky’s breath stuttered once in his throat, just the smallest hitch. Because now, you weren’t analyzing—you were participating.

And he liked that. He liked it a lot.

He wrapped his flesh hand around the base, slow and deliberate, his thumb swiping just under the tip as he started to stroke upward in long, lazy pulls. His cock twitched again in his palm, growing harder with every pass. No sounds left his mouth. His jaw clenched. His brows pulled tight. But he didn’t moan.

He was waiting for you to tell him to.

You shifted in place, thighs pressing together with a sudden, instinctive squeeze. Your breathing went uneven, and the pressure building between your legs was no longer something you could rationalize away. Wetness pooled at the center of your panties. Your skin was hot. Your thoughts a blur of static and want.

Your eyes dropped again. His cock had grown—thicker, longer, flushed deep at the head. Veins thickened along the shaft. The slide of his hand was smooth, practiced. Deliberate.

Your mouth opened again.

“Stroke faster.”

He obeyed instantly.

The rhythm changed, tightened, faster now—fingers gliding up the length, thumb brushing the tip each time in a way that made the muscles in his stomach twitch. His breathing picked up, but still no sound. Still waiting.

You stared.

Hard. Thick. Veined. It should’ve been obscene, but you couldn’t look away. The way his cock reacted to your voice felt like an experiment gone wrong—or maybe perfectly right. And you were the one holding the data, holding the power.

Your pulse beat between your legs.

And then—a glint.

Your eyes caught it before you could process it.

A bead of pre-cum had leaked from the tip, catching the light under the bright med-bay fluorescents. It clung there, glistening.

You groaned.

Not intentionally. Not performatively.

It was raw, low, a breathy little sound dragged straight from your chest before you could clamp it down.

And when you realized what you’d done, your hand flew to your mouth.

Bucky’s fist slowed for just a moment.

Then he smirked—eyes dark, blown wide, a faint sheen of sweat forming across his collarbone.

“That wasn’t very professional,” he murmured.

—

Bucky’s fist moved faster now—stroking with a pace that was no longer lazy or exploratory. It was urgent. Determined. Testing both your commands and his own control.

His eyes flicked up to you again, and this time his voice had a rasp to it. Thicker. Needier.

“Come on,” he said lowly, just above a whisper. “What’s next, huh? Moans? Touch? You’re running the experiment, right? Gotta get all your data points.”

The words coiled low in your abdomen like a tightening wire. He was pushing you now—not resisting, not breaking the role—but tempting you to go further. Daring you.

And fuck, you were already too far gone to backpedal.

You watched the way his cock jerked in his hand, the head flushed and leaking. The pace was obscene—wet, rhythmic, fast.

“Stop,” you said, breathless but firm.

His hand froze instantly, mid-stroke.

You stepped closer, chest rising with shallow breaths.

“Now grip it tight. At the base. Like a cock ring.”

His jaw clenched. But he obeyed.

Fingers slid down, wrapped tight at the base. The moment he squeezed, his hips jolted just slightly—a tiny thrust he didn’t mean to give. The muscles in his stomach twitched. His lips parted.

A whimper escaped him. Soft. Strained. Like it had been forced through grit teeth. Not a moan. But close.

Your own breath caught.

Something about that sound—his frustration, his restraint, the way he held himself back on your order—sent a hot wave crashing through your core.

Your nipples peaked, the fabric of your bra suddenly too tight, too abrasive, like even the fibers couldn’t stand not touching you directly. Heat spread low in your belly, soaking between your thighs. You didn’t dare look down at yourself. You didn’t need to.

You already felt how soaked you were.

Your eyes didn’t leave his cock.

It twitched slightly in his grip.

Alive.

Waiting.

You swallowed, and then—

“Moan for me.”

He did.

Not a pornographic moan. Not some overdone, fake gasp. It was real.

It started low in his chest, almost like a growl — rough, full of restraint snapping open. It vibrated in his throat before it left his mouth, his jaw slackening as he let out a slow, masculine moan that sounded like it had been pent up for hours.

“F-fuck—” he gasped, voice catching. “That what you wanted?”

It was full of yearning. Of weight. Like he’d been aching to be heard, and now your voice was the only one he’d obey.

Your thighs squeezed again, tighter this time. You shifted on instinct, trying to ease the pressure building deep inside you. But it was no use.

He saw it.

Saw you squirm, saw your chest rise like you couldn’t catch your breath, saw the tremble in your fingers now clenched around the edge of the tray behind you.

And he smiled.

But this one… wasn’t mocking.

It was sharp. Almost feral.

His hand still gripped the base of his cock, skin tight and flushed. But he didn’t move. He just looked at you, pupils blown wide.

Then—his voice dropped to something darker. More commanding.

“Your turn.”

You blinked.

“What?”

His smirk widened just slightly, voice gravel-smooth, no longer soft or playful.

“Take the gloves off,” he said. “Then touch me. And let’s stop pretending this is still about Hydra.”

—

For a moment, you hesitated.

Just a breath.

Then you peeled off your gloves—one hand, then the other—fingers flexing slightly in the cool med-bay air. The sterile barrier was gone now. There was no pretending this was still clinical. This wasn’t about notes. This wasn’t about data.

This was about him. And you.

Your footsteps were slow, measured, as you stepped the last bit of distance between you and Bucky. He stood in front of the med-bed, body bare from the waist down, cock flushed and leaking, his chest rising just a little faster now.

You reached out.

Your fingers wrapped around him—replacing his own grip at the base. He let go immediately, lifting his hand away to let you take over, the breath in his throat catching as your skin made contact.

He was hot. Heavy. Alive in your palm, twitching slightly as your hand encircled the base. The skin was soft where it needed to be, velvet over steel, and the tip was slick and pulsing.

You looked up at him.

Your gaze met his, and his eyes were dark, narrowed—hungry.

His lips parted just slightly, voice rough and short.

“Stroke me. Then blow me.”

The order made your thighs clench.

You obeyed without speaking.

Your hand began to move, slow at first, adjusting to the shape and heat of him, your grip gentle, exploratory. You watched the way his stomach flexed with each pass, the subtle twitch of muscle when you passed your thumb over the tip, smearing the pre-cum slowly down the shaft.

You leaned in.

Just slightly at first, tilting your head forward, your breath skating warm over the flushed head. Bucky’s eyes dropped to your mouth.

Then your tongue slipped out—just a taste.

One slow lick, right over the tip.

He groaned. Low. Guttural. His head tipped back for a split second, throat flexing.

You licked again, bolder this time, then wrapped your lips around the head of his cock and drew him in—slowly. You hollowed your cheeks slightly, using just enough pressure to feel him respond, the weight of him dragging your mouth open more as you took him deeper.

Your hand didn’t stop moving.

You stroked while you sucked—your fist gliding up and down the base in sync with your lips pulling wetly around the top. The angle made it easy, almost natural, to slide into a steady rhythm. Before long, your knees found the cold tile beneath you, and you dropped fully down.

On your knees for him.

Bucky’s hand reached for you.

His fingers threaded through your hair—not yanking, not controlling, but guiding. His palm cradled the back of your head, gentle but firm, keeping you steady, helping you move with him.

“Fuck,” he breathed. “Jesus—you feel…”

He didn’t finish the sentence.

He didn’t need to.

You felt it—every twitch, every surge. You could taste him. Hear the sound of your mouth working over him—slick, lewd, hot. His cock throbbed under your tongue, and your hand was slick with saliva and pre-cum now, sliding faster, keeping pace.

Your thighs were soaked. You didn’t dare check.

This was no longer about commands.

This was about the way he moaned when your lips sank lower.

About how his hips gave a slow, helpless jerk when your tongue curled underneath.

About how your name—or maybe a prayer—slipped from his lips like he was giving in.

—

Bucky’s moans were getting ragged—too close. You could feel it in the way his hand tightened at the back of your head, the subtle twitch in his hips, the tremble riding down the backs of his thighs. He was losing control.

But then—he stopped.

His cock slid from your mouth with a wet pop, strings of saliva still clinging as he stepped back, and his hand released your hair with a gentleness that contrasted the tension still buzzing in the air.

You blinked up at him, breathless. Lips swollen, jaw slack.

Confused.

He leaned down suddenly, close, the blunt edge of his nose brushing your cheek, his mouth ghosting against your ear.

“I gotta stop,” he said, voice thick and wrecked. “If I keep going, I’m gonna come—and that’s not how I want this to end.”

Before you could speak, he inhaled sharply, slow and deliberate—right near your neck, your shoulder.

“I can smell you,” he whispered, so close you could feel his breath. “So sweet… fuck, you smell good. Like heat. Like need. It’s all I can fucking think about.”

Your throat tightened. Your thighs instinctively pressed together, but it was no use. Your panties were soaked through. You could feel it now—sticky against your skin, the telltale ache of need building deep and low.

He pulled back, eyes locking with yours.

“Get on the bed.”

You didn’t think. You just moved.

You climbed onto the med-bed, hands shaking as you laid flat, the sterile paper beneath your back crinkling under you. Your chest rose and fell too fast. Your heart was hammering.

Bucky stepped up beside you, fingers moving straight to the controls along the side panel. You watched him adjust the platform—angling it upward, shifting it higher, higher—until your hips were raised perfectly at the edge, aligned with the height of the rolling med-chair he pulled in behind him.

Then his hands went to your waist.

He hooked his fingers into the waistband of your uniform pants—flicking the button open, tugging down the zipper slowly.

His eyes stayed on yours the whole time.

The fabric slid down your hips, over your thighs, exposing your underwear—already ruined.

His gaze finally dropped, and the sound he made was primal. A low, breathless groan punched straight from his chest.

“Fuck,” he breathed. “Look at that.”

Your panties were dark with arousal, wet from center to seam, clinging to your folds. His thumb grazed the soaked cotton, dragging it along the sticky heat there.

“You’re this wet for me?” he murmured. “Just from watching me stroke my cock?”

You swallowed but didn’t answer. You couldn’t. Your hips tilted slightly into his touch, searching for more.

He hooked his fingers under the waistband and peeled your panties down, slow. As he pulled them off your legs, he paused—his eyes lingering for a heartbeat too long on the soaked gusset—and groaned again under his breath.

If he brought them to his nose, you didn’t see it. You were too busy trying not to tremble as he settled between your thighs.

He grabbed the chair, dragged it forward with one hand, and sat—his eyes level with your cunt now, bare and glistening, exposed completely on the edge of the bed.

“You ever had someone eat you out?” he asked, voice deep and low.

You shook your head. Small. Honest.

A flicker of something passed over his face—dark and pleased. His pupils blew wide, tongue wetting his bottom lip.

“Good,” he said, breath ghosting hot against your inner thighs. “I want to be the first.”

Then he leaned in—and licked you.

The first pass of his tongue was slow, wide, and devastating. A drag from your entrance up to your clit in one long, shivering stroke.

You gasped, back arching. “Oh—!”

He moaned into your cunt, low and deep.

Again.

He licked you slower now, more deliberately, the slurp audible. He nosed into you, spread you with two fingers of his flesh hand and devoured you like it was the only thing he was built to do. His tongue circled, then flattened. Then flicked—messy, wet, perfect.

Your hips twitched. Your hand flew to the bed rail, fingers clenching tight.

“Bucky—” you whimpered, voice trembling.

He grunted into you—sound vibrating straight through your clit.

Then you felt it.

Cold.

His vibranium fingers slid between your folds.

One pressed at your entrance—gentle, firm. A slow stretch as he slipped it in, knuckle by knuckle, filling you in one smooth thrust.

You cried out. Your thighs jerked.

The coldness of metal inside your hot, fluttering walls was overwhelming. You clenched around it instinctively, hips rocking into the sensation.

“Shit—yeah,” Bucky rasped, pulling back enough to speak. “Clenching already? Fuck, you feel good.”

His mouth returned to your clit, tongue circling, then sucking, lips closing around it just right.

At the same time, that finger started to move. A slow, deliberate rhythm. In and out, curling just slightly.

You whimpered. Your eyes squeezed shut. The heat building between your legs was unbearable.

“More—” you gasped. “I want—”

You didn’t finish the sentence.

You didn’t have to.

Because your body had already betrayed you—back arching, hips bucking, slick dripping down to his palm.

His mouth sucked harder, tongue flicking faster, finger fucking you deeper—and you felt yourself start to unravel.

His breath hit your cunt when he spoke again.

“You want more?” His voice was rough, dark. “Say it. Tell me what you need.”

—

Your back arched as the first vibranium finger curled inside you, drawing another soft whimper from your lips. You needed more. The pressure was good—but not enough. Not yet.

Your hips rocked forward instinctively, searching, rolling toward his mouth, his hand, anything he’d give.

“Please,” you breathed, voice trembling. “Another…”

Bucky didn’t hesitate.

Another cool, sleek finger joined the first, easing in slowly with a delicious stretch that made your thighs jerk open wider. He groaned against your cunt as he watched your body react.

“That’s it,” he murmured, lips brushing against your inner thigh. “Take it. Just like that.”

Your hips rolled, desperate for more friction. The pressure was growing deeper, stronger—but it still wasn’t enough. Your moans grew softer, more frequent, broken by panting breaths. You couldn’t form words. Couldn’t ask.

But he knew.

Without needing permission, he slid a third vibranium finger inside you, and that made you cry out.

“F-fuck—” you gasped, legs shaking.

The stretch was intense—your walls clenching tight around the cool metal, fluttering with every slow curl of his fingers. You didn’t know you could feel this full from just fingers. But the pressure was perfect. Overwhelming. Too much and not enough at the same time.

Bucky groaned, his own voice ragged now.

“Fuck, look at you,” he said, voice thick and reverent. “Clenching around me like you’re starving for it.”

He set a faster rhythm, fingers pumping into you with slick, wet sounds that filled the space between your own needy moans. His thumb slid up, circling your clit while his tongue flicked beneath it, and it was too much—your thighs shaking, your breath coming in shallow, desperate bursts.

Your hands gripped the rail above your head. Your body was so close, teetering, right there—

And then he stopped.

Just like that.

You whimpered, a broken sob of air as your hips bucked forward, trying to chase the friction he just took away.

“No—” you gasped.

He didn’t answer. He just sat back slightly, eyes hooded with heat, breath heavy, fingers soaked in your arousal.

He raised his hand to his mouth.

Licked the wet off one finger.

“Fuck,” he muttered. “You taste so sweet. Addictive.”

Then, to your surprise, he brought those same fingers to your lips.

You parted them without thinking.

The taste of yourself hit your tongue—salty, musky, warm. It made you moan softly, eyes fluttering closed.

Bucky’s hand dropped, and he leaned over you, one arm curling around your waist as he pulled you upright from the bed in one swift, effortless move. Your legs wrapped around him loosely, chest pressed to his, your soaked cunt still throbbing.

He kissed you.

And it wasn’t rushed. It wasn’t desperate. It was claiming.

Slow. Deep. The kind of kiss that spoke everything his mouth couldn’t say. Tongue sliding against yours, hands anchoring you close, his cock thick and hard between your bodies.

You broke the kiss first, breath catching in your throat. A soft moan escaped you as you leaned into the crook of his neck, lips brushing his jaw, your breath hot against his ear.

“I need your cock,” you whispered, voice shaking. “Inside. Now.”

He jolted. Just slightly—but you felt it. The way his fingers dug into your hips, the way his cock twitched hard against your stomach.

“Are you sure?” he asked, voice rough. “We don’t have to go that far. I can just—keep going. Oral only. Or I can stop.”

But you weren’t having that.

You pulled back just enough to look him in the eye.

Your voice steady now. Low. Commanding.

“It’s a command. Fuck me. Use your cock.”

Something in him broke.

His expression shifted instantly—lips parting, pupils dilating, breath punching out of him like you’d knocked the air from his lungs. And then his hands were on your hips, dragging you down the bed, adjusting your angle.

“Yes, ma’am,” he breathed.

—

Bucky stepped in close, hands firm on your thighs as he aligned his cock at your entrance. You were still clinging to him from the kiss—legs locked around his waist, hips tilted forward—and the tip of him slid through your slick folds, gliding right up to your clit.

You gasped. Your arms tightened around his shoulders.

He let his forehead rest against yours, breath hot between your lips.

“Gonna split you open real slow, doll,” he whispered, voice dark and low. “Wanna make sure you feel me for days. Wanna make you think of my cock when you’re sittin’ at that medic desk, squirming in that chair…”

You whimpered, breath catching hard in your throat.

He shifted his hips slightly, the fat head of his cock nudging right at your entrance. There. Warm. Heavy.

“Still okay?” he asked, eyes scanning your face.

You nodded quickly—too fast.

But Bucky didn’t move yet.

He was patient. His flesh hand slid to your lower back, supporting you. His vibranium arm cradled under your thighs. You were secure. Held. Open.

He pushed in slowly.

The stretch was immediate.

Your breath hitched. Your brows pinched tight.

It wasn’t pain. It wasn’t discomfort.

It was just—a lot.

So thick. So full. Your walls struggled to accommodate the girth of him, every inch pressing into you with that impossible, deliberate pressure.

Your fingers clawed slightly at his back, seeking grounding. Your lips parted around a breathy, trembling moan.

He stilled halfway.

“Talk to me,” he whispered. “Need me to stop?”

You shook your head. “Just—need a second. You’re…”

“I know,” he muttered, placing a soft kiss against your temple. “You’re taking it so well.”

His cock twitched inside you, and the sensation made your core flutter around him again.

You adjusted your hips subtly, trying to find that sweet angle, and he caught your eyes—dark, hungry, but still gentle.

You gave him a tiny nod.

“Okay.”

He eased forward again, the rest of him slowly sheathing inside—inch by thick inch—until his hips met yours and you were completely full.

You both paused.

You gasped softly, still trying to breathe through the stretch. He stayed still, letting you feel everything: his length, his weight, the way he filled every space inside you like he was made for it.

Then—he began to move.

His hips rolled forward, slow and deep. A drag of thick cock against tight, soaked walls. You moaned quietly into his neck, your arms around his shoulders as he rocked into you with careful, steady rhythm.

“Fuck, you feel good,” he groaned. “Tightest fuckin’ thing I’ve ever felt. Gripping me like you don’t wanna let go.”

You didn’t. Couldn’t. Your body wrapped around him like instinct, taking everything he gave, hips jerking slightly with each push forward.

The pace stayed tender, but every thrust got a little deeper.

He lifted you slightly with each one, your thighs trembling around his waist.

But after a while, he slowed again—kissed your jaw, your cheek, the corner of your mouth.

Then his voice dropped.

“Turn around for me.”

You blinked up at him, dazed. “What?”

“Wanna see you bend over that bed,” he said, voice rough. “Wanna fuck you from behind. Real slow. Let you feel every inch while you arch that back for me.”

You moaned.

He slowly pulled out—slick and thick and aching—then gently set you down on the mattress.

The bed hissed slightly as he adjusted the height down, just enough to allow your knees to hit the floor if needed. You leaned forward, hands braced on the mattress, spine arching as he guided you into place.

Your cunt throbbed—open and wet, dripping for him.

“That’s it,” he muttered behind you. “Just like that.”

Then he slid back in.

Your mouth dropped open with a gasp as his cock filled you again from behind—this time deeper, the angle hitting something different, something devastating.

He kept his hands firm on your hips, pulling you back gently as he rocked forward. The rhythm wasn’t hard—but deliberate. Controlled. Every stroke sank to the hilt, then withdrew just enough to let you feel the drag before he shoved back in.

You whimpered, braced against the bed, flushed from the neck down.

And he just kept going.

“Still good, baby?” he murmured, thumb brushing over the curve of your lower back.

You nodded, nearly trembling. “S-so good…”

But the words were starting to fall apart.

So was your mind.

And neither of you had even come yet.

—

Bucky’s thrusts deepened, hips rolling into yours at a steady, dragging pace. Each stroke hit just right, and you were keening for him—barely holding yourself upright, knuckles white as you clutched the edge of the med-bed beneath you.

But then his rhythm slowed.

You gasped when he slipped out, your empty cunt fluttering at the sudden loss. Before you could speak, his hands were already guiding your hips—flipping you over with a gentleness that made your heart twist.

You landed on your back.

He hovered over you for just a beat, gaze sweeping your face.

Then he leaned down and kissed you—slow and tender. Like a thank you. Like a promise.

“Lie back,” he murmured against your lips. “Wanna see your face when you come.”

Your cheeks burned. But you obeyed.

You slid further onto the mattress until you were lying flat, arms at your sides, heart pounding in your ears. He followed—climbed onto the narrow bed, the space barely enough for him, but he made it work.

He settled between your thighs again, and without a word, lined himself up.

Then—he pushed back in.

Your body stretched around him once more, the delicious fullness making you gasp. He groaned softly above you, head dropping to your shoulder.

And then he started to move.

Still gentle—but faster now.

Deeper. The strokes came in a rhythm designed to wreck you, his hips driving into yours, the mattress squeaking faintly beneath the both of you. His mouth hovered over yours, your foreheads touching, breath shared.

You looked up at him—really looked—and something in your chest cracked open.

He was flushed. Focused. Eyes trained on every expression you made. Every gasp. Every tremble.

“You’re so close, huh?” he whispered, voice rough. “Can feel you squeezing me.”

You nodded, breath caught in your throat. Your hands gripped his shoulders now, fingers digging into his back.

“Bucky—” you choked. “I’m— I’m coming—”

His mouth found yours as you shattered beneath him.

Your entire body clenched around his cock, heat surging through you like a wave breaking. Your walls pulsed tight around him, spasming with every beat of your climax. Your legs shook. Your fingers trembled. Your voice caught somewhere between a moan and a sob.

And he kept going—just enough to help you ride it out, hips rocking in slow, shallow thrusts as your body twitched and trembled beneath him.

“That’s it,” he whispered. “Just like that. You did so fucking good…”

When your spasms started to ease—when your cunt stopped fluttering and your hips finally slumped against the mattress—he pulled out, slick and twitching.

His hand wrapped around his cock, stroking hard and fast.

You could barely watch, breathless and dazed, but the sight of him, flushed and towering above you, fucking his fist with your arousal still shining on him—it was filthy in the best way.

A few strokes later, he came.

Hot ropes spilled across your lower belly, streaking your thighs in thick, warm pulses. He grunted low, teeth clenched, brows furrowed as his release overtook him.

You lay there, wrecked. Chest heaving. Skin slick with sweat.

Bucky? He panted for a moment—but that Super Soldier thing had him steadying fast. He leaned down and pressed a soft kiss to your stomach, just above the mess he’d made.

Then he reached for the tissue box by the tray.

You flinched when the cool wipe hit your thigh, but he was gentle—careful as he cleaned the sticky remnants off your skin. His touch wasn’t sexual anymore. It was care. Quiet. Wordless.

He helped you sit up, tugging your pants back into place like it was second nature. Buttoned them for you. His fingers lingered at the waistband.

Neither of you spoke right away.

You didn’t need to.

There was no awkwardness. No guilt. Just… this unspoken truth between you.

This would happen again.

You both knew it.

Bucky looked around the room once everything was cleaned—bed straightened, gloves tossed, no trace left.

Then he turned to you, mouth tugging at one corner in a crooked grin.

“Maybe next time,” he said, voice low, “we try sex on command, too?”

You laughed softly, breath still shaky.

You nodded.

“Yeah,” you said. “For documentation purposes.”
