The mission had been straightforward at first: infiltrate the abandoned research outpost, gather intel, and get out before anyone noticed.
But when the teamās extraction was delayed, you and Bucky found yourselves trapped inside the buildingās dusty corridors, waiting for backup.
After the constant, usual bickering and insults, he left and you heard his footsteps retreat down the hall as he scouted ahead, his metal arm clanking softly with each step. You stayed close to the cracked wall, nervously fingering the strap of your gear. Wishing there were windows to bring in any source of light throughout the creepy dim building.
Suddenly, Buckyās footsteps stopped. Silence swallowed the hallway. Slight worry grew over you, as you take a look down the hallway, however, no sight or sound of him to be found.
When you finally heard footsteps again, you quickly peaked your head past the doorway down the hallway. Seeing Bucky approach, his movements were slower, heavier. His dark eyes held something unreadable ā a flicker of distraction mixed with a strange heat.
You noticed the sweat beading at his temple, the way his breath came a little too fast, a little too shallow.
āBucky?ā Your voice curious, concern knitting your brows.
He didnāt answer immediately. Instead, he leaned against the doorway, jaw clenched tight, hand pressing over his mouth as if trying to catch his breath.
Your heart pounded. You couldnāt just stand there.
Carefully, you took a few steps closer, eyes scanning his face for any sign of injury or distress. āAre you hurt? You donāt look well.ā
Your fingers hovered uncertainly near his arm before gently laying it on the flushed skin.
The contact made him flinch, a sharp intake of breath escaping his lips, and his whole body tensed under your touch.
He looked at you, confusion clouding his dark eyes before darting his eyes away. āI⦠I donāt know whatās happening,ā he admitted quietly, voice strained. āI canāt⦠focus.ā
You bit your lip, cheeks burning with a mix of worry and something else you couldnāt name.
Despite your hesitation, your fingers lingered, tracing the line of his jaw slowly.
His heavy breathing filled the tight space between you.
He wasnāt the bold, direct, and frankly asshole of a man youād expected to come backā he was confused, vulnerable in a way that made your heart ache.
And yet, beneath that confusion simmered something primal, waiting to break free.
You swallowed hard, fighting the urge to pull back as Buckyās gaze locked with yoursādark, confused, and somehow raw in a way youād never seen before. His chest rose and fell rapidly, breath hitching like he was struggling to steady it.
āDo you need to sit down?ā you offered softly, voice barely above a whisper. You hated how your own hands trembled, but you couldnāt just leave him like this.
Bucky shook his head slowly, jaw still tight. āNo,ā he said, voice rough, āI just⦠need a moment.ā
You edged closer, feeling the warmth radiating off his body, the subtle tremor running through his muscles. Your fingers brushed again against his skināthis time along the softer flesh of the inside of his wrist, inspecting his seemingly pulsing veins.
He flinched again, that sharp intake of breath turning deeper, ragged. His eyes fluttered closed for a second, turning his face away from you as if trying to contain something he didnāt understand.
āBuckyā¦ā Your voice softened, uncertainty threading through every word. āWhatās going on?ā
He opened his eyes, dark pools swirling with confusion and frustration. āI donāt know,ā he said roughly, voice breaking just slightly. āI feel⦠wrong. Hot. Like Iām⦠burning up from the inside.ā
You bit your lip, heart clenching. The man who is feared, whoās a deadly super soldier, was now trembling under your touch, vulnerable and raw.
Without thinking, your hand moved to rest flat against his chest, feeling the rapid thud of his heartbeat beneath your palm.
His breathing hitched, eyes darkening as if the simple contact overwhelmed him. āDonātā¦ā he growled out, voice hoarse.
The room seemed to shrink around you both, heavy with unspoken tension. You wanted to pull away, to respect his boundaries, but your body betrayed youādrawn to him like a moth to flame.
āBucky,ā you whispered, āIām here. Iām not going anywhere.ā
Your palm pressed against his chest, trying to calm the wild thumping of his heart. Buckyās breath was ragged, uneven, like he was barely holding himself together. His dark eyes flicked toward you, filled with confusionāand something raw, unfiltered.
He growled softly, a frustrated sound. āI ran into some kind of room in the west wing with a bunch of plants. They were releasing some kind of gas. I donāt know what itās doing to me, butāā He cut himself off, jaw tightening. āāitās making me feel things. Things I donāt like.ā
You raised an eyebrow, and try to lighten the mood. āOh great. Just what I needed: Barnes, the grumpy tin man, suddenly turned into a hot mess.ā You say softly, rolling your eyes with a slight smile
He scowled but didnāt deny it. āKeep it up, and I might just knock that smug smile off your face.ā
āYeah, yeah. Not like this you wonātā you teased, voice light despite the tension.
Bucky took a deep, shuddering breath. āDonāt tempt me. Besides, this isnāt a joke. I donāt know how to control it, and I donāt want you getting involved.ā
You stepped closer, still wary but unable to look away. āSince when did you care what I think?ā
His eyes darkened, and he took a half-step towards the other side of the room, like you might be contagious. āSince this gas has me all messed up and Iām not sure Iām still me.ā He growls out
You bit your lip, trying not to let your cheeks betray how much the sight of him like this was affecting you.
āLook,ā he said, voice low and rough, āI understand that weāre partnered up for this mission, butāā His voice cracked slightly, āright now⦠I need you to just stay out of it. Or maybe just donāt make it worse.ā
You raised your hands in mock surrender. āFine. But only because Iām curious whatāll happen next.ā Not sliding in the tid-bit that youāre still extremely worried for him no matter how aggravating he may be or how many times heās insulted you back at the avengers tower.
Buckyās glare was sharp, but something softer flickered beneath it before he turned away, trying to hide the vulnerability that scared him.
Buckyās back was stiff as a board as he leaned against an abandoned table in the room, jaw clenched tight, but the rapid rise and fall of his chest gave him away. The gas wasnāt just messing with his headāit was twisting something deeper, something primal he clearly didnāt want to admit.
Without a word, he suddenly stepped closer, the heat radiating off him intense and raw. His dark eyes locked onto yours with a sharpness that made your breath catch.
Then, almost abruptly, his hand reached out and grabbed your wristāhis grip firm but not cruel.
His voice came low and rough, like gravel scraping over steel. āYou donāt get it. This gas⦠itās messing with me. Making me feel things I shouldnāt.ā
You blinked, caught off guard, heart pounding.
He swallowed hard, eyes darkening as if fighting to hold himself back. āI donāt want you involved. Hell, I donāt want anyone involved. Especially not you.ā
You stepped back slightly, wary but steady. āJust cut deeper why donāt you.ā You say dripping with sarcasm.
Buckyās jaw tightened even more. Standing in silence very clearly thinking something through despite the haze heās under. āI feel like Iām starting to lose controlāand youāre the one thing thatās driving me crazy.ā
His breath hitched. āI donāt want this. I donāt want to want you.ā
Your cheeks flushed but you didnāt pull away.
He hesitated for a moment, then leaned in just enough for you to feel his breath on your skin.
āDonāt make me lose it,ā he warned, voice rough and low.
The closeness of his face, feeling the hotness of his breath fanning over your skin, the tone of his voice. You canāt help but to begin breathing heavily. Despite you and Buckyās mockery, insults, and arguing, you canāt help but be affected by how heās acting towards you right now. Your eyes scan over him as you fail to resist the squeezing of your thighs and the feeling of molten heat pool in your stomach.
You notice his nostrils flare and his eyes close, inhaling deeply as he lets out a low groan. His eyes open and burned into yours, fierce and unyielding, but underneath there was a raw vulnerability that made your chest tighten. He walks closer towards you, making you back up until your back hits the cold concrete wall. The tension between you wasnāt just the usual snark or competition anymoreāit was something sharper, hotter, dangerous.
Bucky closed the last few inches and pressed his palm flat against the wall beside your head, trapping you gently but firmly. His metal fingers brushed lightly against your temple, and a flicker of something desperate crossed his face.
āYou donāt know what this is doing to me,ā he muttered, voice thick with frustration and something darker. āIām not⦠me right now. And I donāt want to hurt you.ā
You swallowed hard, nerves sparking but your gaze steady. āYou wonāt.ā
He swallowed again, chest rising and falling faster now, like every breath was a fight.
Then, almost reluctantly, his hand found yoursāfingers curling around yours, cool against your skin but firm, possessive.
āIām warning you,ā he breathed, his voice dropping lower, āif you let me, I might not going to be able stop.ā
His gaze flicked down to your lips, then back up, heavy with unspoken promises and desperate need.
You felt your heart hammer in your chest, caught between fear and the undeniable pull drawing you closer to him.
Buckyās grip tightened around your fingers, a low growl rumbling deep in his throat. His dark eyes searched your face like he was looking for permissionāand maybe begging for it too, though his pride wouldnāt let him say so.
āI donāt want this,ā he snarled softly, voice rough and raw, ābut Iām losing the fight.ā
His breath hitched, hot and ragged against your skin. The heat radiating off him was suffocatingāan almost tangible force pulling you closer, burning away the space between.
You wanted to pull back, wanted to remind him that you werenāt sure what this was either, that this was the opposite of professional, opposite of what you two wereābut something in his expression held you fast, unsteady and trembling.
His metal hand slid from your fingers to your wrist, then higher, tracing the delicate skin of your forearm. Every inch was electric under his touch, like you were both alive on a knifeās edge.
āTell me to stop,ā he whispered hoarsely, voice thick with frustration, āand I will. But if you donātā¦ā
He closed the distance suddenly, lips brushing a harsh, breathless kiss against yoursārough and demanding, like he was trying to ground himself through the contact.
Your breath caught, shyness warred with a fierce, blooming heat deep inside you.
Buckyās hands framed your face, thumbs brushing over your cheekbones as if trying to memorize every line, every trembling breath.
āIām scared,ā he admitted, voice low and vulnerable beneath the roughness. āScared I wonāt be able to pull back.ā You feel him physically trying to restrain himself from pulling himself closer to you.
You swallowed, heart pounding louder than your thoughts.
āNo,ā you whispered, voice soft but sure. āDonāt pull back.ā
His lips instantly found yours, crashing into your lips, with a wild insatiable hunger. There was no gentleness in it, just raw need and the taste of restraint shattering. He gripped your waist, his hands big and calloused, roughly pulling you flush against his body like he needed you to stay anchored to the ground.
You gasped into him, the sound catching in your throat as you felt the heat of himāevery line of muscle, every tremble in his body that betrayed how hard he was fighting to stay in control.
āI shouldnāt want this,ā he growled, voice rough against your lips, ānot with you⦠not like this.ā
But his hands didnāt stop. One slid up under your shirt, skimming over your ribs, fingertips dragging goosebumps in their wake. His touch was desperate, reverent, like he needed to memorize your body just to keep from coming undone.
āI didnāt even like you,ā he muttered hoarsely, forehead resting against yours, breath ragged. āYou always ran your mouth, always got under my skinā¦ā
Your hands clutched at the front of his tactical shirt, heart pounding against your ribs. āYou didnāt like me?ā you managed, breathless.
āI hated how much I noticed you,ā he growled. āHow I couldnāt stop watching the way you moved⦠how you looked at me like you saw past the metal and my history.ā
You whimpered as his fingers slipped beneath your waistband, teasing the skin just above your underwear. His touch wasnāt tentativeāit was firm, claiming. Possessive. But there was a tremble in it, like he wasnāt sure if he was about to worship you or ruin you.
āTell me to stop,ā he whispered again, voice cracking with restraint. āPlease.ā
But you couldnāt. All you could do was look up at him, seeing him, pieces of hair falling in his face, his dark eyes staring into yours and let out a soft needy whine.
That was all he needed.
His mouth moved to your neck, kissing and biting, the sting softened by the heat of his tongue. His hand slid into your pants, cupping you firmly. The gasp that tore from your throat only made him press closer, lips brushing your ear.
āFuck, youāre warm,ā he groaned. āSo softā¦ā
His fingers dipped lower, teasing over your folds, dragging a moan from you that made his grip falterālike your voice alone was a match to dry gasoline.
āYouāre gonna ruin me,ā he muttered, pressing his forehead to your shoulder as his fingers slipped inside you, slow but thick and deep. āDonāt even know if this is the gas anymore⦠or just you.ā
You could barely breathe, body melting into his as he thrust his fingers slow and deep, watching your every reaction like he was starving for it. He was so careful despite the desperation coiled in his musclesāhis touches growing rougher, but still holding back that last thread of restraint.
His fingers, curling just enough to make your knees shake. You gasped, a tremor running through your thighs as you clutched at the front of his suit, but Bucky didnāt rushānot yet.
He growled under his breath, forehead still pressed to your shoulder, lips ghosting against your skin as his fingers dragged slick and steady inside you.
āGoddamnā¦ā he breathed, voice broken with awe and frustration. āYouāre driving me out of my fucking mind.ā
You whimpered, your breath shallow. āBuckyā¦ā
His name made him shudder.
He pulled his hand away too soon, and you let out a small sound of protest. Bucky met your eyes thenācompletely unguarded. His pupils were blown wide, his lips slightly parted, sweat shining along his jaw.
āDonāt look at me like that,ā he muttered. āIām hanging on by a thread.ā
You werenāt sure if that was a plead, command or a threat.
Then, you could feel the thick bulge of him straining against his pants, grinding against your soaked core through the fabric of your clothes.
āFeel that?ā he rasped into your ear, rutting against you. āThatās what youāre doing to me. And I havenāt even gotten inside you yet.ā
Your breath caught. His words lit a fire in your belly, made your thighs clench, made you ache.
His hand slipped down again, running two fingers over your clit.
āFuck. Youāre soaking.ā
The curse slipped through his teeth like a prayer as your eyes roll back at the heavenly friction of his hand.
You whine once more as he brought his fingers up and stared at themācoated in your wetnessāthen met your eyes again as he sucked them slowly into his mouth.
Your legs nearly gave out. āBuckyā¦ā you mutter.
āIām not gonna fuck you yet,ā he said, voice rough and tight like it hurt to say it. āNot until youāre begging for it.ā
You whined, hips rolling instinctively toward him, chasing friction.
āOh, you like that?ā he murmured darkly, hand sliding between you again, rubbing slow, heavy circles over your clit. āThe mouthy little agent who never shuts up⦠canāt even form a sentence now.ā
You were panting, your body hypersensitive to every stroke, every drag of his rough voice.
āI want to ruin that attitude,ā he growled. āMake you forget how to talk. Make you cry.ā
His fingers dipped inside you again, thrusting slow and deep, each stroke deliberate and angled just right. You clenched around him, a soft cry leaving your lips, and he chuckled low and sharp in your ear.
āThere it is,ā he whispered. āThatās what I wanted. So fucking tight around my fingers already.ā
His metal hand slid up your shirt, palming your breast through your bra, thumb flicking across your nipple with just enough pressure to make your back arch. āYou gonna fall apart just from this?ā he taunted, voice husky. āWe havenāt even started yet.ā
āBuckyāā you gasped.
āNo,ā he cut in, hot breath against your neck. āNot yet. You donāt get to come until I say.ā
Your head hit the wall behind you with a soft thud, pleasure cresting inside youātoo much, too slow, not enough.
Buckyās mouth moved to your jaw, your throat, licking and biting as his fingers fucked you slow, precise, dragging you closer to the edge and pulling you back again and again.
āYou think I donāt see the way you look at me?ā he whispered. āLike you hate me. But underneath it? You wanted this. You wanted me.ā
Your moan betrayed you.
He grinned against your throat, then sank his teeth into the delicate skin thereānot enough to hurt, just enough to make you gasp. His hand never stopped moving, never gave you what you needed all the way. He was relentless, teasing, every inch of him vibrating with tension and barely held control.
āI could keep you like this for hours,ā he muttered. āDesperate. Soaking wet. Shaking.ā
He dragged his fingers out of you and pressed them between your lips.
āTaste how sweet you are,ā he said roughly. āAnd tell me you donāt want me.ā
Your mouth opened before you could stop yourself, and the taste of your own need sent heat rushing straight to your core.
Bucky growled. āFuck, thatās it. Thatās what I wanted.ā
He pushed his hips into yours again, the thick, throbbing heat of him pressing right against your clit through the fabric.
āYou ready?ā he asked darkly. āBecause once Iām inside you, Iām not stopping.ā
You were trembling beneath him, body pinned to the wall, soaked and aching. Every nerve ending buzzed under the weight of his mouth, his hands, his voiceādragging you to the edge, over and over, without mercy.
And still⦠he hadnāt taken you.
Until now.
Buckyās jaw flexed like he was still trying to fight itābut the look in his eyes told you he was past the point of no return.
āI told myself I wouldnāt,ā he growled, lips ghosting over yours. āTold myself I could ride it out. Wait for backup. Do the right thing.ā
He leaned in, pressing his forehead to yours, his hips grinding against you in a slow, punishing circle. You felt himāthick, hard, straining inside the confines of his pantsāand your breath hitched.
āBut I canāt fucking think straight,ā he whispered, almost like it hurt. āNot when youāre this wet. This soft. Looking at me like youād let me break you open.ā
You didnāt say a word. You couldnāt. The air was thick with your shared breath, hot and humid, and your voice had long since abandoned you.
He slid your pants down, low enough for you to shimmy and step out of them. He reached down, undid his belt with shaking hands, and freed himselfāthick and heavy and flushed, the head already leaking. The sight of it made your thighs clench instinctively.
Bucky groaned at the sight of you. āFuck, look at you. So shy all the time, but nowā¦ā he leaned towards you, grabbed your thigh and wrapped it around his waist. He pushed your soaked underwear to the side, lined himself up and paused, metal hand gripping your thigh, holding you open, holding you still.
āLast chance,ā he rasped. āYou want me?ā
You look up at him with pleading eyes and a whine, āplease, Buckyā¦.ā
That was all it took.
He thrust forward in one deep, brutal stroke,
burying himself inside you to the hilt. You cried out, nails digging into his arms as your body stretched to take him.
āShit,ā he gritted through clenched teeth, eyes screwed shut. āSo fucking tight. You feelāGodāyou feel unreal.ā
He held still for a beat, shaking from the effort not to lose it too fast. But you clenched around him, and he groaned low in his throat, head falling to your shoulder.
Then he started to move.
Each thrust was deep, rough, and controlledābut just barely. He was shaking with it, like he couldnāt believe how good it felt, like every time he slammed into you it pulled a piece of him loose.
āYou like it rough, sweetheart?ā he growled against your ear.
But you were already goneāmoaning, head back against the wall, gasping as your body met his rhythm instinctively. You give a messy nod.
āYeah,ā Bucky snarled, gripping your ass and lifting you a little higher so he could drive in deeper, your leg not wrapped around his waist barely touching the ground. āYou take me so fucking good.ā
The sound of skin slapping echoed off the walls, the wet slick of your arousal making each brutal thrust louder, messier.
āYou think I donāt see you?ā he grunted, voice ragged. āAlways biting your lip around me, looking away. Playing innocent. But youāre not.ā
His pace picked up, hips slamming into yours harder now, deeper. āYou want this. Youāve always wanted this.ā
āBuckyāā you whimpered, voice cracking.
āSay it,ā he growled. āSay you want me.ā
āI want you,ā you gasped, clinging to him.
He cursed viciously, his control unraveling at the sound of your voice.
āFuckāIām not gonna lastāā he bit out, slamming in deeper with each thrust. āYou feel too goodātoo tightāIāve neverāā
He cut himself off with a broken groan, his lips crashing against yours in a searing kiss, swallowing your moans as he fucked you harder, rougher. Your body was shaking, teetering right at the edge, and he could feel it.
āCome for me,ā he commanded, voice thick and guttural. āNow.ā
And with one last, brutal thrustāhe hit the spot that sent you spiraling.
You shattered around him, crying out, trembling as your climax tore through you, soaking him. Bucky followed instantly with a strangled groan, burying himself deep as he came hard, hips jerking, forehead pressed to yours as he gasped your name like a lifeline.
His hips slowed, but only slightlyājust enough to ride out his own release as you trembled around him, body slack and twitching in his hold. But he didnāt pull out. He didnāt ease away. He stayed inside you, panting against your neck, every muscle still coiled tight like a predator that hadnāt fed nearly enough.
You whimpered softly as his cock throbbed still-hard inside you, impossibly thick, sensitiveābut not softening. Not even a little.
āā¦Youāre still hard,ā you breathed, dazed.
Buckyās shoulders shook with a low, humorless laugh. He dragged his mouth up your throat, tongue catching on the sweat at your collarbone before he murmured, āI know.ā
His voice was darker nowāgravel scraping over flameāand when he pulled his head back to look at you, his pupils were still blown wide, black swallowing the blue.
āThat plant,ā he said, panting, āit did something. I donāt feel normal, Iāā He gritted his teeth and rolled his hips forward again, slow and grinding.
You moaned, sharp and overstimulated, but it only made him groan. āStill not enough.ā
He pulled out just a few inches, dragging his cock against your soaked, sensitive wallsāthen slammed back in with a low, wrecked sound.
Your body jolted, pleasure colliding with sensitivity, making you gasp. āBuckyāā
āCanāt stop,ā he growled. āCanāt. You feel too good. I need more.ā
He hooked your other leg up around his waist, spreading you open and lifting you slightly off the ground. The shift in angle drove him deeper, the stretch unbearable, the pressure mounting again despite how recently you'd come. You were already growing slick around him again, your body betraying your mind as it begged for more.
āI should hate you for this,ā he whispered against your lips. āYou make me insane.ā
āThen hate me,ā you whispered back, breathless.
He snarledāand then snapped.
His mouth crashed to yours, biting and claiming, tongue dragging over your lips before plunging deep. At the same time, he started to fuck you againāharder than before, frantic and relentless, each thrust punching a moan out of you.
You had no defense anymore. No sharp quips, no witty retortsājust Bucky, inside you, growling your name like a curse and a prayer all at once.
āGonna keep you like this,ā he panted, lips brushing your ear. āStuffed full of me. Until you canāt walk straight. Until everyone on comms knows what I did to you.ā
His words hit you like lightning, heat pooling fast and hard in your gut again.
āYou want that?ā he murmured, nipping your earlobe. āWant me to ruin you until all you can say is my name?ā
You couldnāt speak. You could only cry out, moaning shamelessly as he started slamming into you againārough, wild, deep. His grip bruised your thighs, his mouth never left your skin, and every thrust sent stars behind your eyes.
āYouāre mine right now,ā he gritted, pounding into you. āJust mine.ā
Your second orgasm hit harderāsharperāyour body seizing around him with a cry that echoed through the empty hall. You were pulsing around him, milking him, but this time, Bucky didnāt come.
He just groaned and kept going.
His breath was ragged now, like he was in pain from holding back.
āIām not done,ā he choked out, pressing your back tighter to the wall. āNot until Iāve wrung every fucking sound out of you.ā
Then he pulled out, slowly, deliberatelyāand spun you around.
Your hands hit the wall just in time to catch yourself as he dragged your underwear the rest of the way off. You whimper at the cold concrete pushing against your soft chest. His hands gripped your hips, pulling your ass back toward himāand without pause, he shoved himself back in from behind with a deep, wrecked growl.
You gasped, moaning at the new angle, at how deep he felt this way.
His hand came around to your front again, fingers finding your swollen clit, rubbing in messy circles.
āYouāre taking me so fucking well,ā he snarled. āLike you were made for me.ā
The words made you clench, and he hissed through his teeth, hips stuttering.
āSay it,ā he barked. āTell me you want more.ā
āMoreāā you choked, hands scrambling for purchase against the wall. āBuckyāGodāmoreāā
He slammed into you even harder, punishing now, wrecked with need.
āGood girl,ā he growled, voice low.
Your hands braced against the wall, fingers splayed, trying to ground yourselfābut Bucky gave you no reprieve.
His thrusts were brutal now, paced with a rhythm that shook through your entire body. Each snap of his hips pushed a cry from your lips, every inch of him stretching you open all over again, slick from your last two orgasms and still somehow burning for more.
You were soaked. Raw. Quivering.
And he was insatiable.
Behind you, Bucky was panting like a man possessed. His forehead dropped to your shoulder for a second, teeth grazing your sweat-slicked skin as his grip on your hips tightened, fingers digging in deep enough to bruise.
āFucking hell,ā he growled, voice wrecked. āI can feel you squeezing meālike youāre trying to pull me deeper.ā
You moaned, unable to answer. You werenāt sure there were words anymoreājust sensation.
Heat. Pressure. Him.
He slammed into you harder, and your knees buckled, but he caught youāone arm locking around your waist, dragging you up against his chest. Moaning, feeling your body pressed flushed against his. His other hand was still between your legs, fingers working your clit with ruthless precision, flicking and circling until your legs were trembling, your cries coming faster.
āGonna come again,ā he rasped in your ear. āI can feel it. Youāre so close, baby. Give it to me.ā
His metal hand gripped your throatāslightly tight, just enough to tilt your head, to control youāand he sank his teeth into the curve of your neck as he fucked you harder, faster.
You cried out, your body tipping toward the edge again with dizzying speed, your back arching at the intense pleasure.
āSay it,ā he ordered through gritted teeth. āSay you want to come on my cock.ā
āPleaseāBuckyāwant itāfuckāI want it, I want itāā
āThatās it,ā he hissed. āGod, thatās itāgonna make you come so fucking hardāā
You clenched around him, your whole body going tautāand then snapped.
Your climax tore through you like fire, a scream ripping from your throat as your pussy spasmed around him, pulsing, slick, drenching him.
Bucky groaned like it broke him, thrusting deep one last time before he came with a roarāslamming into you to the hilt, cock twitching as he spilled inside, hot and thick, filling you to overflowing.
He held you tight, shuddering, mouth pressed to your shoulder as he rode it outāstill pulsing, still deep inside you.
For a moment, everything was quietājust your panting, the wet sounds of your bodies, and his heart hammering against your back.
Then he finally spokeāvoice low, hoarse, almost reverent.
āā¦Still hate me, sweetheart?ā
You let out a breathless, broken laugh against the wall.
āOnly when youāre not fucking me like that.ā
Bucky chuckled darkly, nuzzling your neck, still buried inside you. āThen I guess Iāll have to keep doing it.ā
Buckyās breathing was still ragged behind you, his broad chest rising and falling against your back. His arms stayed wrapped around your waist, firm but gentle now, as if afraid youād slip away if he let go.
You both stayed like that for a long momentāpressed together, skin flushed and slick with sweat, the heavy sound of your breathing the only thing filling the silence.
Then, slowly, he eased out of you, hissing softly at the overstimulation. You whimpered, sensitive and sore and still trembling, and he caught you as your knees buckled, guiding you gently to the floor.
The moment your back hit the cold wall, you shivered.
āShit,ā Bucky muttered, voice thick and gravelly. āYou okay?ā
You looked up at him, lips parted, dazed. āI think soā¦ā
He crouched in front of you, one knee bent, eyes scanning your faceānot with lust now, but something softer. Something real. His pupils werenāt as blown out anymore. The sharp edge of heat in them was starting to fade.
And for the first time since all this started, you realized⦠the gas was wearing off.
You could see it in his bodyāthe subtle way his muscles unclenched, the way his breathing evened, like his senses were slowly coming back under control.
āā¦Bucky,ā you murmured, still catching your breath, āwhat was that stuff?ā
He exhaled hard, dragging a hand back through his damp hair.
āLike I said earlier, there was a room. Down the hall. Some kind of overgrown greenhouse or lab, I donāt know.ā His voice was quieter now, more grounded. āI barely stepped inside before I started sweating. My head got light, and then everything started to burn. My skin, my blood⦠my cock.ā
You flushed, throat bobbing as your eyes flicked down between you.
He noticed. His jaw tightened.
āI didnāt know what was happening,ā he added, guilt creeping into his tone. āDidnāt understand why I was reacting like that until I saw you again and I justāā
He broke off, shaking his head like he was angry at himself.
āIām sorry,ā he said, finally. āI shouldnātāve touched you. Not like that. Not when I wasnāt thinking straight.ā
But you reached out and curled your fingers around his vibranium wrist, grounding him.
āYou didnāt force me,ā you said softly. āI wanted it. All of it.ā
His eyes met yoursāsharp, guarded, like he was still waiting for the punchline.
āYou sure?ā he asked. Not a tease. Just a whisper of vulnerability cracking through the armor.
You gave a breathless laugh, nodding. āYeah. Pretty sure the three orgasms confirm that.ā
That pulled a small, crooked smirk from himābut it didnāt last. His gaze drifted back to where your bare thighs were still spread, slick and flushed, your pants still tangled around one ankle. You were raw, used, full of him.
And still⦠somehow⦠the tension wasnāt gone.
āYou didnāt hate it,ā he murmured, like he was testing the waters.
āNo,ā you admitted. āAnd⦠maybe I donāt hate you as much as I pretend to.ā
That surprised him.
He tilted his head, lips parting like he had something to sayābut instead, he leaned forward, slowly, giving you the chance to stop him.
You didnāt.
His lips brushed yours, soft this time. Nothing like the devouring heat from earlier. Just a quiet, aching thing. A kiss that said weāre not doneābut maybe not just in a physical way.
You kissed him back, fingers curling into his jacket. And when he finally pulled away, his forehead leaned against yours, breath warm across your face.
āIāll get you cleaned up,ā he murmured, voice husky again, but this time with gentleness rather than hunger.
You nodded, legs still shaky. āYeah. I⦠donāt think I can stand yet.ā
That made him chuckle, low and rough.
āYou wonāt be walking straight for a while.ā
You smacked his chest weakly, and he grinned. It was the first time youād ever really seen him smileānot that tight, sarcastic twist, but something real.
And just like that⦠something had shifted.
The lines that used to keep you on opposite sides of every room were goneāburned away by sweat, heat, and the way his hands had held you like he was afraid of losing something he didnāt know he wanted.
As he helped you pull your clothes back on, slow and careful, your fingers brushed. You didnāt pull away.
Neither did he.

By the time the extraction team touched down, the gas was well out of Buckyās systemābut the aftermath lingered on both of you like a second skin.
He still walked close to you. His arm still brushed yours whenever the hallway narrowed. His jacket, slung loosely around your shoulders, smelled like himāwarm leather and sweat and something darker, primal, something youād felt grinding deep inside you less than an hour ago.
Neither of you had said much since.
Not because there wasnāt anything to sayābut because the weight of everything that had happened still hummed like a live wire between you.
And when the door to the building finally slammed open and Samās voice came over the commsādry, impatient, and absolutely obliviousāyou nearly jumped.
āThere you two are,ā he said, stepping into view in full gear, eyes flicking from you to Bucky. āTook your sweet time, huh? We were about to call it and let you rot in there.ā
Bucky didnāt flinch. He just grunted. āWe managed.ā
Sam looked at the both of you suspiciously.
Your hair was a mess. Your pants were definitely on inside out, despite your frantic fumbling earlier. Buckyās shirt clung to him with dried sweat, and his belt was still hanging open under his tactical vest.
And when Samās eyes narrowed and slid down to the distinct bite mark blooming just beneath your collarbone, visible even beneath the edge of Buckyās jacketā
He froze.
Blinked.
And looked back at Bucky. Slowly.
āā¦Did you fight each other?ā
You opened your mouth, panic rising in your throat.
But Buckyāsmug bastardābeat you to it.
āDoesnāt matter,ā he said coolly, leading the way past Sam without missing a beat. āI won.ā
Sam gawked after him. āYou won what? An STD?!ā
You groaned and followed quickly, cheeks flaming. āShut up, Wilson.ā
āYou shut up!ā Sam called after you. āIām gonna have to Lysol the entire jet, arenāt I?!ā
Bucky didnāt even blink as he climbed aboard.
You shot him a glare as you slid into the seat across from him, keeping your arms crossed even though his jacket still hung around your shoulders like some ridiculous trophy.
The second Sam stepped in behind you, eyeing the both of you like a disgruntled parent, you tried to school your expression into something neutral.
You failed.
Bucky smirked.
āSo,ā Sam said, dropping into the pilotās chair with a sigh. āEither of you wanna tell me why your vitals were going crazy on the monitors for thirty minutes straight?ā
āMustāve been a glitch,ā Bucky replied smoothly.
Sam turned, staring at him.
You were biting your lip. Hard.
āA glitch,ā Sam repeated flatly.
Bucky shrugged, unbothered. āMustāve been the plant gas. Messed with my sensors.ā
āOh, I bet it did,ā Sam muttered, spinning back to the controls. āGod, Iām too old for this.ā
The Quinjet engines flared to life.
You glanced at Bucky. He was watching you from under his lashes, jaw tight, one corner of his mouth twitching upward like he was this close to smiling.
You leaned closer, voice just low enough that Sam wouldnāt hear.
āYouāre really proud of yourself, arenāt you?ā
Buckyās smile turned wicked.
āYouāre the one still wearing my jacket, sweetheart.ā
You flushedāand hated how much it thrilled you.
As the jet lifted into the sky, the tension didnāt fade.
It simply shifted.
No longer the tension of enemies circling each other like knives waiting to clashābut the quieter, heavier kind. The kind that simmers under the surface, waiting to boil over again the second you're alone.
And something told youā¦
This wasnāt over.
Not even close.
Well this is the hottest thing I've read in a while. I've re-read it at least 3 times now. Damn. Just, damn.
