Bucky was staring at you with heart eyes the second you walked into the tower. You’re a scientist who just got hired by the Thunderbolts. The team immediately noticed the way Bucky looks at you. Actually, Alexei noticed first before anyone else.

“Do you have a crush on the new scientist?” Alexei curiously asks.

“I just met her a little bit ago.” Bucky says.

Alexei could tell that Bucky has a crush on you by the look in his eyes. Heart eyes to be specific.

“You should help her unpack her things in the lab.” Alexei suggests.

“Really?” Bucky asks.

“Yes! She’ll love you!” Alexei says enthusiastically, giving him a pat on his back.

Bucky goes to the floor your lab is on. The door to the lab was open when he got there. You were in there unpacking and organizing your stuff. Bucky knocks on the door to the lab, getting your attention. You stopped what you were doing and turned around to see Bucky standing in the doorway of the lab.

“You’re Sergeant Barnes, right?” You asked.

“Call me Bucky.” Bucky walks into the lab. “I was wondering if you needed help with anything.” He says.

“I did most of the unpacking, but I could use your muscles and strength for the heavy stuff.” You say, pointing at the heavy stuff in the corner of the lab.

“Sure thing!” He smiles.

You and Bucky maintained a conversation as he helped you with the heavy lifting. Bucky was throwing heart eyes at you the whole time. Little did the two of you know that Alexei was standing next to the door to the lab, listening to how well you and Bucky are getting along. He grins to himself as a plan begins to form in his head. A plan to get you and Bucky together.

Later, Alexei makes a group chat with him, Yelena, Ava, Bob, and John. He texted them their plan about how you and Bucky should get together. He also mentions that he thinks that you and Bucky would make a cute couple. They didn’t take long to agree with Alexei’s plan. They’re thinking the same thing as him.

So that night when you and Bucky were sound asleep, Alexei quietly snuck into yours and Bucky’s bedrooms to shut off yours and his alarms so you two can wake up later in the morning. He grins to himself as he goes to his own bedroom. He texted the team in the group chat, telling them that he turned off yours and Bucky’s alarms.

The next morning when you and Bucky woke up, you two checked the time on yours and his phone. Yours and his eyes widened when you two realized that you two slept in and your alarms were shut off. Yours two rushed to get ready for the day even though you two don’t have anything important planned for today. You’re still setting up the lab and Bucky has a workout to get in.

“Good morning, Y/N.” Alexei greets you as he walks in the lab.

“Good morning, Alexei.” You greeted him back. “Did you need anything?” You asked.

“No. I just wanted to stop by to say hello.” He says.

“Oh ok.” You replied.

“Have a great day.” He smiles.

“You too.” You smiled back.

The grin on Alexei’s face was clear as day, but you didn’t even notice it. Then Alexei went to the gym. Bucky was lifting weights when he walked in there.

“Good morning, Mr. Soldier!” Alexei chirps.

“Morning, Alexei.” Bucky says.

“How did it go with the new scientist woman yesterday?” Alexei asks, the grin reappearing on his face.

“I think it went pretty well.” Bucky says. “Why do you ask?” He asks.

“No reason.” Alexei replies. “Enjoy your workout.” He says before walking out of the gym.

Bucky didn’t even notice the grin on Alexei’s face either. He went back to his workout. Alexei’s plan is starting off better than he expected.

———

A couple weeks go by since Alexei came up with a plan to get you and Bucky together. His plan is still going great. You and Bucky have gotten a lot closer since the day you two met. Although, you and Bucky are beginning to sense something.

This morning, you walked in the kitchen for a cup of coffee. You got the coffee brewing and then opened the cabinet to get a coffee cup. Due to how short you are, you couldn’t reach it. Bucky walks in the kitchen at the same time you’re struggling to get a coffee cup.

“Do you need help?” Bucky asks as he walks further in the kitchen.

“Can you get the coffee cup for me please?” You asked politely, pointing at the coffee cup you want.

“Of course.” He smiles.

Bucky reaches for the coffee cup and hands it to you. Then he got one for himself. You poured yourself a cup of coffee and then poured some for Bucky.

“I don’t know if you’ve noticed this or not, but have you noticed the team doing things to get us to be alone together?” Bucky asks you.

“Now that I think of it, I’ve noticed it a lot too. It’s like they want us to get together.” You say.

“Whoever came up with a plan to try to get us closer together, achieved it. I think we’ve gotten to know each other really well over the past couple of weeks.” He says.

“Can I admit something to you?” You nervously asked.

“Of course.” He replies softly.

“When I first met you, I thought you were the most handsome guy I’ve ever met. I got lost in your eyes the second I looked into them. Now, all I think about is kissing you.” You admitted.

Bucky puts yours and his coffee cups down on the kitchen counter and cups your cheeks. You looked up at him, getting lost in his blue eyes. Bucky leans down and kisses you sweetly and passionately. Little did the two of you know that, Alexei walks in the kitchen while you and Bucky are kissing.

“THAT’S WHAT I TALK ABOUT!” Alexei cheers, making you two laugh against each other’s lips.

Alexei ran out of the kitchen and looked of the rest of the Thunderbolts while shouting throughout the tower that his plan worked successfully.

“Do you want to go on a date on Saturday night?” Bucky asks.

“I would love to go on a date with you, Bucky.” You answered softly with a smile.

Bucky smiles and kisses you again. You and Bucky are definitely looking forward to yours and his date on Saturday night. Alexei is looking forward to hearing about it afterwards, along with the Thunderbolts.

A soft plink of glass, a hiss of vapor, and suddenly your body was a symphony of wrong sensations. Your pulse thundered, your skin prickled, and before you could even shout for help, the world went green.

“Oh no,” Bruce whispered, eyes wide. “Oh no no no—”

The rest was a blur. Equipment flying. Floor buckling. Tony’s voice screeching through the intercom about “containment protocols.” Bruce sprinting in the opposite direction because the irony was apparently too much for the universe to handle.

And then—amidst the chaos—came him.

“Hey, doll,” Bucky said carefully, standing in the smashed-open doorway with his hands raised.

You growled. Not intentionally—it just happened, a low rumble that made the concrete tremble beneath your feet. You were at least seven feet tall, bright green, and apparently very, very angry about it.

He blinked once. “You, uh… hit your caffeine limit, huh?”

Bruce ducked behind a console. “Barnes, you’re insane, get out of there!”

But Bucky ignored him, stepping closer like you were a cornered animal. Except his voice—his voice was the one thing that didn’t sound afraid. “Hey. I know you’re in there, sweetheart. It’s me.”

The Hulk part of your brain snarled. The you part wanted to die from embarrassment.

He took another step, slow and steady. “Remember when you told me not to put metal in the microwave? You were right. I almost blew up your coffee. Still owe you a new mug.”

You hesitated—giant green fist trembling.

“Yeah,” he murmured, “that’s my girl. You’re still in there.”

You exhaled a growl that rumbled through the lab’s foundations. He smiled—smiled—and reached up, palm out.

“C’mere, sugar.”

And against every law of physics and reason, the Hulk in you listened.

You crouched down, the floor groaning under your weight, and let his flesh hand cup your jaw. It was like someone flicked a switch. Your breathing slowed. The furious buzzing in your ears dimmed. The bright, radioactive green faded to soft human skin—yours—barely covered by a very shredded lab coat.

Bucky didn’t even blink. He just shrugged out of his jacket and wrapped it around you like this was normal Tuesday science stuff.

“You okay, doll?” he asked softly.

You blinked, disoriented. “Did I just—did I—”

“Yeah,” Bruce said from behind a toppled table, “you hulked out.”

“Oh, God.” You buried your face in your hands. “I wrecked the entire lab.”

“Eh.” Bucky tilted his head. “Couple wires. One very terrified Tony. Nothin’ new.”

You peeked up at him, half-horrified, half-dazzled. He still had that faint, lopsided grin, the one that said he’d walk through hell for you and call it a Tuesday jog.

“Why… why did you come in here?” you asked weakly.

He rubbed the back of his neck. “Tony said someone needed to calm you down, and Bruce looked like he was gonna puke. I figured you wouldn’t smash me.”

“I almost did!”

“Almost,” he agreed, grinning wider. “But you didn’t.”

Bruce finally stood, muttering about containment readings and “unexpected resonance with emotional stimuli.” You ignored him, too busy trying not to spontaneously combust under Bucky’s smile.

Two hours later, wrapped in a blanket and sipping tea in the med bay, you watched him leaning against the wall like a Renaissance painting—arms crossed, blue eyes soft, hair falling in his face.

“Stop staring,” you mumbled.

He raised a brow. “You were just seven feet tall and green, sweetheart. I think I earned a couple minutes to make sure you’re still you.”

“You’re enjoying this.”

“Maybe a little,” he admitted, lips twitching. “You scared the hell outta everyone. Tony’s still hiding behind FRIDAY.”

“I’m never living this down.”

“Probably not,” he said cheerfully. “But I like you better this color.”

You glared. “You like me green?”

He shrugged, metal arm glinting. “Didn’t say green. Said you. You’re you, no matter the shade.”

Somewhere behind him, Bruce groaned audibly. “Please, for the love of science, flirt less near the containment units.”

Bucky didn’t even glance back. “No promises, Banner.”

You groaned and buried your face in your hands again. “I can’t believe I turned into the Hulk.”

“Mini-Hulk,” he corrected. “More like… fun-sized.”

“Bucky!”

He laughed—an honest, warm, beautiful sound that made your chest ache. “Alright, alright. You did great, doll. You didn’t hurt anyone.”

“I dented the floor.”

He winked. “Adds character.”

Later that night, after Bruce confirmed you were stable (“Mostly stable. Probably. Just, uh, no more sneezing near chemicals.”), you found yourself in the empty kitchen with Bucky.

He handed you a mug of cocoa, steam curling up into the dim light.

“So,” he said, “does this mean you’re one of us now? Gonna get a superhero name? Gamma Girl? The Incredible Nerd?”

You nearly choked on your drink. “You are impossible.”

He smirked. “You love it.”

You rolled your eyes, but you didn’t deny it. The silence stretched, cozy and charged, like static before lightning.

Finally you asked, softly, “How did you… calm me down? No one can usually reach Bruce when he turns.”

Bucky’s jaw worked for a second before he said, “Guess I just know you.”

You blinked. “You—what?”

He looked away, sheepish. “I pay attention, okay? The way you talk when you’re nervous. The songs you hum when you think nobody’s listening. The look you get when something finally makes sense in that big brain of yours.” He met your eyes, voice low. “I figured if I talked to you the same way, maybe you’d hear me.”

Your heart stuttered. “Bucky…”

He smiled faintly. “Guess I was right.”

You swallowed, setting your mug down before your hands could shake. “You really do pay attention, huh?”

He leaned closer, gaze soft and unguarded. “Always have.”

For a long moment, the only sound was the quiet hum of the fridge and the steady, shared rhythm of your breathing.

Then, because apparently you hadn’t embarrassed yourself enough for one day, you said, “So if I turn green again, you volunteering to be my emotional support super-soldier?”

His grin was slow, dangerous, and stupidly sweet. “Darlin’, I’ll hold your hand through every shade of the rainbow.”

You laughed, cheeks warm. “You’re ridiculous.”

“And you’re still glowing,” he teased. “Not green—just… glowin’.”

You looked up at him—really looked—and realized he meant it. All the teasing, all the banter—it was just a disguise for the truth sitting quietly between you.

You stepped closer. So did he.

“Bucky,” you whispered.

“Yeah, doll?”

“Next time Bruce sneezes, I’m wearing a hazmat suit.”

He laughed, low and soft. “Next time Bruce sneezes, I’m takin’ you to dinner instead.”

You blinked. “That’s not—wait—was that—”

“Yeah,” he said simply, brushing a stray hair from your cheek. “That was me finally askin’ you out.”

You smiled, heart thundering. “Took turning into a Hulk to get you to do it, huh?”

He points a discolored finger at the screen. 

“They really never get these kinds of things right,” he blows out a breath of air that flutters his fringe. 

“It’s just a movie, Leon,” you coo at him, laughter in your voice. “Besides, does it really matter?”

“It might,” he huffs, crossing his arms and putting his biceps on display. 

Your eyes rove over his patch quilt body. Some may call you a mad scientist, but you like to think you’re just enlightened. Besides, if you had listen to those ingrates at the college you would never have ventured off to work on your own experiments, stumbling across the greatest scientific marvel of the eons. 

Leon had been hiding away in some dilapidated shack in a forest far from any civilization. He’s stitched together of various body parts, but overall seems to have most of his original body intact. It’s been a learning experience for both of you—one that’s tipped over into a relationship. 

It’s strange, but it works. Not to mention, the fun things you can do with a man whose body essentially functions as sentient body parts. Fidgeting in place, your thighs press together at the memory of last time Leon let you play around with an idea.

You tug on his arm and his attention swings from the tv over to you. Biting your lip, you drag your fingernail down his forearm. 

“Can we?”

His eyes light up and he grins, “Here or the bedroom?”

“Here, please,” your eyes drop to his lap. 

Wasting no time, his hands reach down to undo his pants, shimmying in place until he can kick them off. He’s half hard but quickly fills out, cock stiff and fat as he strokes himself once.

“You gonna work for it?”

“Uh huh,” you nod your head, eyes glued to his dick while he shifts in place.

With another low grunt, he’s able to remove his cock. The first time it threw you off so much, you stopped everything to study how it worked separate from his body. It’s basically a dildo until it’s reattached to his body once more. He can feel a faint trace of pleasure, which you still haven’t figured out how that works, so you cockwarm him often. 

Standing up, you quickly shed your clothes, standing nude in the living room as the tv blares some classic monster movie in the background. Sitting back on the couch, you press your back to the armrest so your body is facing out toward Leon.  

He places his cock in your outstretched hand, hissing when you press your lips to the tip. Lathing your tongue around the head, you suck him into your mouth before pulling his dick put with a wet pop. Dragging his cock down between your breasts, you watch him track the path you take. You slap his thick length against your soaked slit before grinding the head on your puffy clit. 

“Please,” he groans. “Let me see you stuff your pussy full of my cock.”

Whining in your throat, you do just that. Notching the head of his dick at your drippy hole, you slowly push his cock into your cunt. You both moan as his fat dick spreads you open, filling your pussy. You want to tease him, drag out this heavy tension until he can’t take it anymore, but that’s just not possible. 

He feels way too good inside you—and with the way he’s watching, your belly burns hot with arousal, pussy soaking his cock as you pull it back out to thrust it back in deep. 

“Oh fuck, Leon,” you whimper, head rolling back and forth while you fuck yourself on his dick. “You feel so good in my pussy.”

“Fuck,” he pants, scooting closer to you on the couch. “Is that fat pussy having to work extra hard so I’ll fit?”

“Uh huh,” you mewl. “It’s so big.” 

“Yeah? Need some help?”

You really did want to drag it out but—

“Please,” you sigh, pussy clenching around his cock. “It’s not gonna fit.”

“Aww,” he murmurs. “It’ll fit, you just need me to force it in, don’t ya?”

Nodding rapidly, you whine, “Oh god, yes.”

He bats your hand away and grips the base of his cock. Grinding it against your snug walls, he pulls it out, watching your needy hole clench around nothing. Sitting back, he reattaches his cock and then pulls you over into his lap. 

He bullies his cock back into your cunt and you squeal, pussy and clit throbbing at his rough treatment. 

“Ride me, show me how much you love this cock in your tight hole.”

“Yes, yes,” you gasp, hands gripping his shoulders as you hump your pussy down onto his dick. 

You can’t stop bouncing in his lap, fat cock stretching you open so wide it hurts but in the best way. It makes you even wetter knowing your pussy will be sore and achy tomorrow. Shuddering, you drop down heavily, the drippy tip of his dick kissing your womb and making you squeal. 

“Good girl, taking me in so deep,” he grips your neck and brings you in to a messy kiss, tongue lapping against yours.

His calloused thumb presses into your clit and begins to rub in circles. Keening, you claw at his chest, orgasm cresting higher and higher until it finally breaks. You cry out against his lips, pussy clamping down on his cock while your body judders in his hold. 

He doesn’t let up on your clit and it sends white hot zaps of pleasure throughout your body. Leon keeps you bouncing on his lap, fucking his cock deep against your cervix until he finally stills with a loud groan. Gasping wetly, your walls flutter and milk his dick, feeling as he floods your hole with hot, thick spurts of cum. 

Slumping against him, Leon pets your sides and hips, grunting as your pussy grips and pulses around his half hard cock.
