4. {Sneaky Little B***h}

The gym is alive with the sounds of exertion—weights clanging, heavy breathing, and the occasional grunt of effort. Bucky Barnes and Steve Rogers are currently engaged in a rigorous training session.

Drops of sweat glisten on their foreheads as they spar with each other, their movements a blur of speed and precision. But even the most skilled warriors need a moment to catch their breath, and they now find themselves on a brief break, leaning against the gym's cool metal walls.

Bucky unscrews the cap of his water bottle, taking a long, satisfying gulp of the refreshing liquid. His muscles ripple beneath the sheen of sweat, evidence of the intense workout they've been enduring. Steve wipes his brow with a towel, his chest rising and falling steadily as he recovers his breath.

Meanwhile, it's your turn for the mundane task of city duty today, and you've been paired with Sam Wilson.

Exiting the compound, you find Sam waiting by the sleek black SUV assigned to you for the day. He offers a friendly grin as you approach. "Ready for some excitement, Y/N?" Sam quips, a playful glint in his eyes as he gestures towards the vehicle.

You chuckle in response, "Oh, I'm sure certain others will be having a much more exciting day than you and me, Wilson," you reply with a shrug, though there's a hint of knowing in your voice.

Earlier this morning, a revelation struck you like a bolt of lightning, jolting you from your slumber and propelling you into action. Two days have passed since Bucky once again outmaneuvered you on your shared playing field. Increasingly frustrated with the situation, you resolved to devise something truly brilliant, and brilliant you have.

Under the cloak of the rising sun, you slipped out of the compound, embarking on an unusual errand to a nearby store for the main ingredient of your prank. Upon your return, you headed straight for the kitchen, your mind ablaze with creativity as you set about concocting your idea.

You procure two packets of a specific male enhancement drug, a sly grin forming on your lips as you release each pill onto the counter, relishing the faint clatter they make. Swiftly, you retrieve the nearest blunt object from a drawer and begin pulverizing the pills into a fine powder in a small bowl.

Recognizing that this might be an excessive amount for a typical victim, but considering Bucky Barnes' enhanced abilities, you're convinced that a more potent dose is warranted. With a sense of satisfaction, you dispose of the damning packets in the trash before carrying the bowl back to the bedroom quarters of the compound, poised to await the next phase of your plan.

You linger in your quarters, your senses attuned to the rhythm of footsteps echoing down the hallway as the men make their way to the morning briefing. Among the casual chatter of Sam and Steve, you catch the distinctive tread of Bucky's footsteps, a cue that he's in tow.

Sensing the opportune moment, you seize it, clutching the bowl tightly as you hasten down the corridor toward Bucky's room. With practiced ease, you push open the door, sliding inside with a quick, silent grace, your pulse quickening with anticipation.

Once inside, you waste no time, scanning the room with sharp eyes for the telltale container of workout powder that's a staple for all of them. Each passing second feels critical as you search, the rush of adrenaline heightening your senses and sharpening your focus.

With a surge of satisfaction, you seize the tub of workout powder and allow a triumphant smile to grace your lips. Perching on the edge of Bucky's bed, you waste no time in prying open the lid and deftly emptying its contents into the waiting bowl. Swiftly, you seal the tub once more, giving it a brisk shake to obscure any signs of meddling.

Mindful of leaving no trace, you return the tub to its original position, ensuring everything appears undisturbed. With your mission accomplished, you quietly slip out of Bucky's room, making a swift retreat back to your quarters. There, you hastily prepare yourself to join the others for the morning briefing, the thrill of your covert operation still coursing through you.

As Steve and Bucky continue their sparring session, their movements are fluid and precise, a testament to years of training and camaraderie. The sound of their grunts and the clashing of metal fill the air, echoing through the empty gym.

However, Steve suddenly stops mid-strike, a puzzled expression crossing his features as he notices something quite noticeable happening under Bucky's shorts. His brow furrows in confusion, his focus momentarily diverted from their sparring.

Bucky, sensing Steve's hesitation, takes advantage of the opportunity, launching a swift strike that catches Steve off guard. Steve stumbles backward, narrowly avoiding the blow, but it's enough to snap him back to attention.

"Hey, what's going on?" Steve asks, his eyes flickering down to Bucky's shorts once more, unable to ignore the obvious distraction.

The thing that catches Steve's attention is the unmistakable bulge forming in Bucky's shorts. It's not something he's accustomed to seeing during their training sessions, and it momentarily throws him off guard.

Bucky, realizing Steve's gaze has shifted, quickly adjusts his stance, attempting to conceal the bulge as he glances at Steve with a hint of embarrassment. "Uh, sorry, Steve," he mutters, his cheeks flushing slightly. "Must be the way I'm standing or something."

Steve nods, though he can't shake the feeling of curiosity and amusement. "Yeah, must be," he replies, trying to suppress a smirk. 

As Bucky discreetly adjusts his stance, His eyes flicker to his water bottle sitting nearby, and the realization dawns on him. He remembers the mischievous glint in your eye earlier that day in the morning meeting, and he pieces together what must have happened. His eyes narrow.

"That sneaky little bitch," he mutters under his breath, his tone laced with a mixture of frustration and begrudging admiration for your audacity.

Steve arches an eyebrow, catching Bucky's muttered words. "What was that?" he inquires, his curiosity piqued by Bucky's sudden change in demeanor and undoubtedly feeling a little awkward with the whole ordeal now. 

Bucky's demeanor exudes frustration as he storms out of the gym, Steve trailing behind, perplexed by his friend's sudden urgency. The gym's door slams shut behind them, the reverberation echoing down the corridor.

In the main area, Tony and Natasha are engrossed in conversation, their morning coffee momentarily forgotten as they hear the commotion approaching. Their heads snap up in unison, eyes widening at the sight of Bucky striding in, his gait purposeful and his expression grim. 

But it's what's happening beneath Bucky's shorts that truly catches their attention—a conspicuous bulge that leaves little to the imagination. Natasha's eyebrows shoot up in surprise, while Tony's jaw hangs slightly agape, both stunned into silence by the unexpected sight.

"Where the fuck is she?"

Bucky's demand reverberates through the room, his tone sharp and accusatory, as he locks eyes with Natasha, his frustration clear even from across the room. Yet, Natasha and Tony exchange a knowing glance, silently acknowledging the brewing storm before them.

"Barnes, why the fuck are you walking around the compound with a semi?" Tony inquires as Steve rushes to join them. Natasha stifles a laugh, clearly in on the joke.

"Y/N did this to you?" she queries, setting down her coffee with an amused smirk. Tony and Steve exchange perplexed glances, waiting for Bucky's confirmation.

Bucky grunts in frustration, his irritation evident. "Yeah, she did," he confirms tersely.

"Oh, for the love of... are you two really still at it with this prank war?" Stark sighs, his tone laced with exasperation as he finally grasps the situation. Natasha can't suppress her laughter any longer, and even Steve cracks a smile, unable to resist the humor in the midst of Bucky's embarrassment.

Bucky's frustration only intensifies at the mention of the prank war. "This isn't a joke," he snaps, his tone sharp as he struggles to maintain his composure. "She crossed a fucking line this time."

Natasha raises an eyebrow, her smirk fading into a more serious expression as she takes in Bucky's demeanor. "Okay, calm down, soldier."

But Bucky is in no mood to talk. He turns on his heel, his jaw clenched with determination as he storms out of the room, leaving Tony, Natasha, and Steve exchanging concerned glances in his wake. 

Tony exchanges a curious glance with Natasha, his brows furrowing as he assesses the gravity of the situation unfolding before them. "Should we go after him?" he asks, a note of uncertainty creeping into his voice, unsure of how to handle Bucky's evident frustration.

Natasha shakes her head slightly, her demeanor composed and unruffled despite the tension in the room. "Let him cool off for a bit," she advises, her voice steady and reassuring. "I'm sure he's going to need some time to process everything. Perhaps an hour or two." She stifles another laugh, her eyes twinkling with amusement even as she maintains her composure.

The other two join in the laughter, the tension of the moment easing as they share in the absurdity of the prank war unfolding before them.

"They've certainly raised the stakes since the last time this was going on," Tony muses after their laughter subsides, his tone contemplative as he reflects on the escalating antics between Bucky and you.

"Oh, if only you both knew," Natasha sighs, a hint of mystery in her tone as she keeps her own understanding in the prank war under wraps, leaving Tony and Steve intrigued by her cryptic remark.

As you return to the compound after several hours, you find Natasha waiting for you in the main area, a mischievous glint in her eye. She wastes no time in catching you up on the situation with Bucky, her tone laced with amusement as she relays the details.

"Y/N, you're in for it," she says, barely able to contain her laughter. "Bucky's not happy about what happened earlier. He's been locked in his room since."

You can't help but chuckle at the thought of Bucky's reaction, finding the whole situation incredibly amusing despite the impending confrontation. Natasha joins in your laughter, her eyes twinkling with mischief as she revels in the chaos.

"Thanks for the heads up, Nat," you reply between giggles, trying to stifle your amusement. "I'll handle it."

"Oh, I'm sure you will. I'll tell the team that you both will more than likely not make it for dinner and drinks tonight?" She teases, knowing and offers her a brief side glance, nodding in agreement to her suggestion. 

"Yeah, probably best," you reply, still grinning at the thought of Bucky's reaction. "I have a feeling we'll be busy sorting things out." You quip, making your way to the elevator to head up to Bucky's quarters. 

As you make your way to the elevator, Natasha's parting words reach your ears, eliciting a laugh from you. "Can't wait to hear all the juicy details!" she calls out, her voice echoing in the hallway as the elevator doors slide open. With a wave and a grin, you step inside, ready to face whatever awaits you in Bucky's quarters.

Arriving at Bucky's quarters, you inhale deeply, gathering your composure before rapping lightly on the door. Anticipation hangs heavy in the air as you await a response, your thoughts a whirlwind of speculation on Bucky's potential reaction to your playful prank. Yet amidst the nerves, a flicker of excitement ignites within you.

The door swings open, revealing Bucky's stern countenance, and you brace yourself for the impending confrontation. Without a word, he pulls you into the room with a fierce grip, the door slamming shut behind you. His bare torso glistens in the dim light, his gaze intense and hungry as he wastes no time in asserting his dominance, his physical presence leaving no room for protest.

You're caught off guard as Bucky pulls you into the room with a hunger in his eyes, his actions leaving you momentarily speechless. The sound of the door slamming shut echoing in the room as Bucky's intense gaze locks onto yours.

Your heart races as you take in his shirtless form, his defined muscles glistening with a light sheen of sweat. The bulge beneath his boxers serves as a constant reminder of the prank you played earlier, intensifying the tension between you.

Before you can utter a word, Bucky closes the distance between you, the heat of his body against yours sends enticing spark throughout, igniting a primal desire within you.

"You've gone too fucking far, this time, Y/N," he growls, his face mere inches from yours. "Hours I've been like this!"

His voice is laced with frustration and desire, his breath hot against your skin as he speaks. You can feel the intensity of his emotions radiating off him.

You respond with a teasing tone, your voice barely above a whisper as you defend your actions. "In my defense, I wasn't sure how much of a dose to use, so I used it all." As you speak, you can feel the undeniable pressure of his hardened member against your leg, a physical reminder of the effect your prank has had on him. 

His laughter resonates with a low, dangerous rumble, echoing in the intimate space as he compels you further into the room, each step a deliberate advance that prompts a reluctant retreat on your part. The edges of the bed abruptly meet the back of your legs, causing you to stumble backward and fall onto the soft mattress, abruptly finding yourself face-to-face with his package.

But Bucky's not done. He presses forward, his towering frame looming over you, casting a shadow that engulfs your figure. With a swift movement, he forces you back onto the bed, his presence dominating the room as he hovers above you.

Dragging yourself up the bed, your gaze meets his intense stare, every fiber of your being aware of the electrifying tension between you. His voice, low and commanding, resonates through the air, cutting through the silence with its weight.

"So, what are we going to do about this?" He questions, his tone laden with authority. "Because you're not leaving this room until we resolve this issue."

You swallow hard, meeting Bucky's intense gaze with a mixture of nerves and excitement filled by the raw desire emanating from him.

With a defiant glint in your eye, you hold his gaze, refusing to back down. "Well, Barnes," you retort, your voice steady despite the racing of your heart. "I suppose we'll just have to figure out a way to... relieve the tension, won't we?" 

As he lowers his head, his lips brush against your neck, his touch sending a jolt of electricity coursing through your body. A sharp gasp escapes your lips as he nips at your skin, each touch igniting a fire within you that threatens to consume you whole.

Your breath catches in your throat as Bucky's next sudden movement takes you by surprise, and you let out a startled yelp as he flips you onto your stomach. With a firm yet gentle touch, he straddles your legs, effectively pinning you in place beneath him. 

Your heart races as you feel the weight of his body pressing down on yours, the anticipation building with each passing moment. You wait with bated breath as Bucky's hands move with purpose, yanking your pants down to your ankles in one swift motion. 

Your skin tingles with excitement as he pulls down his own boxers, the air thick with the promise of what's to come. With a primal hunger in his eyes, Bucky positions himself, his desire evident as he prepares to take what he wants.

Your breath catches in your throat as you feel Bucky's flesh hand glide over your slick center, the sensation sending a jolt of pleasure through your body. He groans, satisfied, "Fuck, you're so wet already, doll." He says a little breathlessly as he uses the moisture from you to lube himself up, moaning lightly as he does and he lines himself up with your entrance, leaning over to quickly whisper to your ear, "Sorry, sweetheart no time for foreplay today." He utters before he slams into you hard in one quick motion. 

You gasp at the feeling and he continues to slam into you hard and fast, causing the bed to shake beneath the two of you. His hands grab your hips as he thrusts into your tight hole over and over again.

You can't help but moan as he pounds into you, his cock filling you up completely. You feel so full and stretched out, but it feels so good. His hands grip your hips tighter as he continues to fuck you hard and fast. 

"Fuck, Y/N." Bucky growls with impatience, his movements firm and fast as he sets a rhythm that leaves no room for hesitation. The frustration and longing from the past few hours are evident in every thrust, driving him to seek release with fervor.

You're a moaning and whimpering mess as he continues to fuck you. You feel so good, and it feels so good to be fucked by him. His cock is filling you up completely, and it feels incredible. "Bucky!" Is all you can cry out, urging him on further. 

As he shifts your hips upwards, positioning you on your knees, you instinctively place your elbows underneath you for balance. The change in position sends a wave of blissful pleasure coursing through you, and you can't help but cry out in ecstasy, the new angle allowing him to penetrate even deeper.

His metal hand maintains a firm grip on one of your hips, guiding you back into his thrusts with a commanding force. Meanwhile, his flesh hand reaches forward, tangling in your hair to create a makeshift ponytail hold, eliciting a chorus of cries from you as he intensifies the pleasure, "Fuck, Bucky!" You moan out, "I'm going to cum." 

He groans at your words and fucks you even harder, both his grips tightening. "Do it," he growls, "cum for me, doll." You dig your nails into the bedsheets as you feel the orgasm build up inside of you. You cry out as it hits, and he slows down to let you ride out the wave. He doesn't stop though and keeps fucking you through your orgasm until he grunts out in his own pleasure, and you feel him release inside you. 

He slows down to let you ride your orgasm out as the pleasure overwhelms you, you collapse onto your face, unable to maintain your balance on your elbows any longer. Your body surrenders to the ecstasy coursing through you, every nerve on fire with sensation. Bucky collapses on top of you, his weight pressing against your back, but not enough to crush you. Both of you lay there, panting heavily, the room filled with the sound of your ragged breaths as you come down from the intense high of your shared passion and eventually, he slowly pulls his cock from you. 

As Bucky rolls to the side, you follow suit, lying on your back beside him. Neither of you says a word, the only sound filling the room being the rhythmic pattern of your breathing. Your eyes drift upward, gazing at the ceiling as you both catch your breath, the air heavy with the aftermath of your intense encounter.

"Damn, you're a good fuck." Bucky breaks the silence, his gaze fixed on the ceiling as if lost in thought. You turn your head to look at him, noticing the subtle rise and fall of his chest, the sheen of sweat glistening on his skin in the dim light.

"I'm sure that's the Viagra talking," you quip, a breathless laugh escaping you. Bucky chuckles in response, a smile playing at the corners of his lips, his eyes crinkling with amusement as he shakes his head lightly.

"Never do that again," he suddenly says, turning his head to meet your gaze. His eyes narrow at your prank, but there's a hint of playful admonishment in his tone. You press your lips together lightly to hide the smile tugging at the corners of your mouth.

You meet his gaze, feeling a surge of warmth at the playful glint in his eyes. "No promises," you reply, unable to resist teasing him further. Bucky lets out a mock sigh, but there's a hint of amusement in his expression.

"Stubborn as ever," he remarks, a fondness evident in his tone as he reaches over to gently brush a strand of hair away from your face. You lean into his touch, relishing the intimacy of the moment.

As the realization dawns on both of you, a sense of awkwardness fills the air. You both sit up abruptly, a silent agreement passing between you to regain some semblance of normalcy.

You quickly crawl to the end of the bed to retrieve the bottom half of your attire, feeling Bucky's eyes on you as you hastily dress yourself. His gaze lingers, a mixture of amusement and something softer that you can't quite place.

"Well, I suppose I better get going," you announce, attempting to break the tension with a light-hearted tone. "Leave you to figure out your next prank on me, Barnes." With a final adjustment of your clothes, you stand up, ready to make your exit.

Bucky nods in response, his expression unreadable as he watches you. "Looking forward to it," he replies, his voice carrying a hint of mischief. As you turn to leave, you can't help but feel a flutter of anticipation mingled with uncertainty.

With one last glance over your shoulder, you offer him a small smile before slipping out the door, the lingering tension between you serving as a reminder of the complex dynamics at play in your relationship.
