Bucky holds up his right hand. “AGENT Y/L/N, no! What did you do?“ There’s something in his voice you’ve never heard before. Panic, fear, even. “We gotta get out of here.”

He covers his mouth and nose with his gloved hand. “OUT!”

“Out?” You look around the room. Everything was normal a few seconds ago, and now the former Winter Soldier looks like he saw a ghost. “Sergeant, we have our orders. Captain Rogers wants us to secure the information.”

“OUT!” It’s more of a growl than a word. Bucky takes one step toward you, still covering his mouth. “Y/N, stop talking back for once. We need to…”

His whole body suddenly sizes up. The strong and undefeatable super-soldier falls to his knees. He slams his fists into the ground.

“Sergeant?” You step away from him. Bucky is a little broody, grumpy even. But the man kneeling on the ground stares up at you with glowing eyes. “Sergeant Barnes?” Now you panic. He slams his metal fist into the ground. “You’re scaring me.”

“You…” He growls deep and guttural. “You need to run. Go now.” Bucky seems to fight with an invisible force. He rams his fist into the ground to keep himself from getting back up.

“Why?” You are panicking now. “Sergeant? What’s wrong? Are you sick?”

“I can smell your pussy,” he snarls in your direction.

“What?” You drop your eyes to your crotch. Can he really smell that his closeness arouses you? You heard that alphas could smell when you are fertile, but can he smell your slick too? "Sergeant, we can’t leave. Why do you want to leave?”

“I won’t be able to stop myself.” Bucky groans loudly as he rams his metal fist into the ground again. “OMEGA!” He purrs low in his throat.

“Oh. God.” You step back, shaking your head, when he gets back on his feet. Bucky cracks his neck and flexes his metal arm. He stares at you like he wants to eat you alive.

“RUN!” It’s the last warning you’ll get. Bucky is close to losing his mind. His alpha is taking over, and there is no rational thought left.

You finally set things into motion and run out of the room. While Bucky growls your name, you try to get in contact with Steve and the rest of the team.

“Captain Rogers, this is an emergency. I think something is wrong with Sergeant Barnes,” you pant while looking over your shoulder. “Can you hear me? Copy?”

All you get is radio silence. Crap. This is the worst time to lose contact with your team.

“OMEGA!” You shriek when you hear Bucky chase after you. Fuck, for a man his size, he’s fucking fast and stealthy. “Come here.”

Like a wild animal, he chases after you, growling your name as you start running again. Your heart thunders in your chest, and your brain goes a mile a minute. You’re torn between following his alpha command and the fear that causes you to run faster.

Until now, you believed that Bucky would never hurt you. But he’s not himself, and you fear he’ll kill you if he gets his hands on you.

He didn’t warn you for nothing.

“Stop running from me.” He’s so close you can smell his sweat. Fuck, how can that fucker run so fast without being out of breath? “OMEGA!”

“Sergeant,” you stumble back. “You need to calm down.” You raise your hands. “I know that I broke the vial, but that’s no reason to kill me!”

“Kill you,” he bares his teeth and chuckles. “I won’t kill you.” You swallow thickly as his eyes drop to your crotch. “I only want to claim what’s rightfully mine.”

Bucky dips his head. He smirks, and you swear, it looks like the fucker is having a blast chasing you around.

“Sergeant,” you giggle. “I’m flattered really, but…uh…this is not the time to think about your knot.” You point at him. “I don’t want you to do something you’ll regret.”

His eyes darkened at your words. “Stop running away from me. Give up. This is your fault for breaking the vial. You released the sex pollen.”

“Sex pollen?” You release a shuddery breath as the realization hits you. Sex pollen. You heard that term before. Doctor Banner mentioned it months ago. “No…this can’t be. It shouldn’t exist any longer.”

Bucky watches you like a hawk. Every move you make gets noticed by him. He’s an apex predator, an alpha, and a super-soldier with higher senses. Outrunning him won’t work out for you.

“Captain Rogers, can you hear me,” you whisper into the void. Your earpiece is useless. White noise is all you hear. “Fuck…”

Bucky smirks darkly when you lick your lips. He looks like a wild wolf with his teeth bared and his eyes glowing. “They want me to mate you, omega.” He sniffs in your direction. “Lucky me, getting such a nice little pussy today.”

“Hah, yeah…you’re very funny.” You show your palms while slowly walking back. One step, after another.

Bucky cannot know that your panties are soaked and that you’d love to have him on top of you. He’s your supervisor and a fucking super-soldier. You’re not sure if you can take him.

What if he breaks your hips? You giggle at the thought, feeling silly. Bucky would never be interested in mating you. Right? Right…

“I told you to run,” he growls now. “I need to mate you.” Bucky curls his shoulders, eyes glued to you. His eyes flick to your face when you move back again.

“Can you not…jerk it out of your body?” You must sound hilarious because Bucky snorts at your comment. “No?” You frown. Bucky tries to fight the toxin; you can see it in his eyes.

“Come. Here,” he spits while talking. “OMEGA!”

You remember Bruce’s words now. Sex pollen was created to make the alphas compliant. A forced rut and an omega in heat were all they needed to control the soldiers. If they refused to mate, the sex pollen would kill them.

“Sergeant,” you slowly take a step back, and another. “I know you believe you must mate me. Believe me, I like me a good fuck but we’re in the middle of a mission.”

He grins darkly. Bucky watches you turn on your heels to go for a sprint. His growls echo through the abandoned building when you run along the corridor.

You don’t stand a chance. The fucker is fucking thick, and beefy but damn him, that man can run. He goes for a sprint, catching up with you in no time.

You feel his breath before he pounces on you. He tackles you to the ground, immediately burying you under his heavy body. “Sergeant,” you snarl feeling his lips nip at your neck. “This is inappropriate.”

Well, no shit. His erection is pressing against your ass, and you can tell, that man is packing. While Bucky tugs at your tactical suit, you wonder if his dick is another perk of being a super-soldier or if he was packing before Hydra got their hands on him.

“Hey, what,” you whimper when Bucky cuts your tactical suit open. He’s done fooling around. He needs to feel your cunt around him. “I liked that suit.”

You groan, and mutter but it’s no use. Bucky rips the remnants of your brand-new suit down your body before you can call him a jerk.

“Omega,” he hums in appreciation while staring at your exposed body. “Mine.” You debate to get up and try to run again. Bucky is much faster than you, he proved it more than once today. Plus, you always had a thing for the grumpy man.

You hate yourself for it, but you lie still and listen to him cursing and growling. Not because you are scared of fighting him, but to save his life. If the test results Doctor Banner told you about are true, Bucky could die if he doesn’t fuck the toxin out of his body.

“Fuck,” he curses behind you. Bucky is on you again, to cover your body with his large, hard one. He ruts against you, hoping to ease the pain in his groin. Bucky presses his aching cock between your legs, moving against your clit. “Mine…only mine.”

If anything, he gets even harder feeling your slick cover his length. “Sergeant,” you wiggle your hips. If he forces you to feel his dick, you want to have him inside of you. “Fuck…” You pant heavily.

He’s growling incorrect words in your ear. You don’t understand a thing, only your name and that he wants to breed you.

His skilled hands, made to defeat any enemy, carefully lift your butt to line himself up with your soaked hole. Bucky fully sheaths himself inside your welcoming warmth with one hard thrust. He whines into your neck, ready to pop his knot anytime.

Mine. Mine. Mine. He chants in his mind while slowly starting to rock into you. Bucky never felt so welcome inside a body.

His powerful thrusts make you groan. He’s mounting you like you’re some animal, but your body greedily welcomes him.

Bucky grips your hips, holding you pinned to the ground. “Mine.” His movement becomes erratic when you start to whimper his name. He doesn’t stop. Bucky plunges into you, with only one thought left; to breed and claim you and your body. “Mine…”

“Fuck… Sergeant…” you wiggle your hips, unable to meet his thrust. “I’m gonna…” Shit… fuck… it’s too late. Your cunt grips him tightly, forcing his knot to expand. Bucky sinks his teeth in your neck the moment his release fills you.

“Shit…” Bucky won’t let go of your neck. He grunts against you, feeling his knot lock you together. “What did you do?”

“I,” he finally releases your neck to stare at your now-marked mating gland. He releases an inhuman noise before rutting into you a few more times. “Mine…”

You’re too exhausted to argue. His body still presses you to the ground, and his knot won’t deflate for some time. Lying still you close your eyes and allow yourself to rest for a moment. It’s all too much.

Bucky moves his arms around your body and buries his face in your neck. He nuzzles you while feeling the fog clouding his mind slowly start to fade away.

“Y/N! BUCK!” You stiffen underneath Bucky when you recognize Steve’s voice. “BUCK!”

“Capsicle, can you slow down?” Tony whistles the moment his eyes land on Bucky’s naked ass. He snickers and decides to snap a few pictures. “Buckethead, that’s not how we train our rookies,” Tony tsks.

“Tony,” Steve grunts. He looks anywhere but at his friend and you buried under the heavy alpha. “Can you just not.”

“I told you it’s an emergency,” you mutter from under Bucky. “You didn’t listen.”

“What happened?” Steve tries to find out what happened while Tony snickers behind his back. “Tony, just stop it.” He angrily raises his fist.

“Sex pollen,” Bucky slurs. “She dropped sex pollen.” He huffs into your neck. “I had to breed her.”

“Yeah, can you not tell anyone about our little breeding escapade, Sergeant,” you grumble. It’s worse enough that Captain America and Tony walked in on you.

“Steve, some privacy please,” Bucky wraps his arms tighter around your body to roll to his side to take his weight off of you.

Steve gives Tony a stern look. He huffs and jerks his head toward the entrance. “Let’s give them some time. Sex pollen is the worst…”

Tony furrows his brows. “How do you know, Capsicle?” He follows Steve outside the building. “Did you…you know…experience it too.”

While Steve and Tony fight over his phone and the pictures he took of Bucky’s naked ass, Bucky nuzzles you and murmurs your name.

He worriedly looks at you in his arms, sighing deeply. “Are you cold? I can’t move but I can roll on my back. I’m sorry about…uh…everything.”

“I don’t want Tony to see my naked ass…” You both start laughing at that. There’s a lot to talk about, especially the fact that Bucky claimed you…”

Part 2

Chapter 1 - a beautiful baby boy

“Mama?”

Billy flicked his tail and watched the bubbles come up to break the surface. They were floating on the bull kelp canopy, Billy’s head resting on Mama’s belly, the sun shining down on them.

“What is it, Billy Blue?” Mama asked, running her fingers through his curls. Spending time in the ocean with Mama was Billy’s favorite thing to do in the whole world. They’d found a small cove away from the tourist areas and it was their secret spot. There, they could let out their tails and forget about the human world for a bit. 

Sometimes—when they had more time because Billy's dad was away for work—they would swim down to the city under the sea, where they met merfolk like them and Mama would show him the history of their people, painted on large murals in the library.

Billy knew Mama used to work at the palace, but then something bad happened and Mama left her job. They didn't talk about it. The people they met in the deep of the ocean didn’t mention it either, but they were always happy to see Mama and Billy. 

They didn’t seem to like Billy’s dad very much, though. Billy wondered if it was because his dad was human, and sometimes not very nice. He felt bad thinking such things, but he’d heard tales about humans who did horrible things to merfolks. Mama said that was why they needed to hide the truth about their tails.

Billy flicked his tail a few more times. He liked how the sun reflected on his scales. Mama had told him the colors of his tail would change as he aged, going darker. He hoped his tail would look like hers, dark red and gold, with spots of black. Mama’s tail was so pretty.

“Can you tell me about the stolen prince?”

“Again?” Mama said with a laugh.

“Please, Mama.”

“Alright,” she said, dipping her fingers in the water and letting the drops fall on Billy’s cheek. “It was a bit over a year before you were born. After years of trying and hoping, Queen Titania finally had a child. A beautiful baby boy—”

“Like me!” Billy exclaimed with glee.

“Yes, my darling, like you.” Mama smiled and picked up Billy’s hand to give it a kiss. She kept it as she continued the story. “He had big brown eyes, and equally brown hair, and he was named Stephanos. The whole queendom rejoiced and merfolks came from all over the ocean to see the little prince. There was enchanting music and endless dinners with fancy foods, and a lot of dancing. It was such a happy time.”

“Then the bad men came…”

“That’s right. When Prince Stephanos was a few months old, two men sneaked into the palace and stole the baby. The palace guards looked everywhere but they couldn’t find the men or the little prince. The queen was so heartbroken that she refused to leave her chambers for a long time.”

“Poor lady.” Billy didn’t like that part. He had seen the queen a couple of times when Mama had taken him to the underwater city, and she had looked so sad. He hoped Mama and him were never separated like the queen and her baby had been.

“The high council sent the royal secret service to look for the prince everywhere, even on land. But it’s been over ten years, and they still haven’t found him. A few weeks after the prince was taken, I found out I was pregnant with you, so I left my job at the palace to be with your father, up here.”

Mama stopped talking then, and Billy looked up at her. She looked sad, a bit like the queen. He wondered why, since he was still there with her.

“I love you, Mama. I always want to be with you.”

Mama smiled down at him, but he could see the tears in her eyes, even if they didn’t fall. “I love you, too, Billy. No matter what happens, you will always be my precious boy.”

Shortly after, Mama decided it was time to go home. They swam to shore where she waited on the sand for him to focus enough to switch to two legs. He was still learning how to control the transformation, finding, like many other merchildren, that going from two legs to a tail was easier than the reverse. 

“It’s too hard, Mama. I can’t,” Billy said, frustrated and tired. Mama shushed him, her soft hand brushing his cheek as she kissed his forehead.

“It’s okay, baby, it takes time. It will come to you with more practice. Here,” she handed him the enchanted necklace that prevented merfolk transformations on land. Billy would need to use it when bathing and swimming around humans, until he could control his tail.
