Fated Mates

You had been crying in pleasure just a minute ago but now you pressed your face on the crook of Bucky’s neck and cried in frustration. Bucky kissed the top of your head, his hand soothing your back. His scent was comforting and so was his knot keeping his cum inside you, but as you were sated, your hormones turned into a different direction. 

The last five months had been messy. After recognizing Bucky you had shown up at Steve’s apartment because Natasha had long given you his address as she knew you were mates. 

The only reason Steve hadn’t shut the door on your face was the man standing next to you. Bucky was Steve’s mate who he thought dead. And while Bucky had trouble recognizing his own name, he had recognized Steve as his mate immediately. When Steve had held him, Bucky had rubbed his back as the Captain cried, his scent comforting. 

You watched with longing, but stayed rooted to the entrance until they parted. Having two mates wasn’t unheard of, but it was rare. Even more rare given that if Bucky and Steve had lived their lives in their time, they wouldn’t have met you.

They hadn’t stayed in the apartment long after you explained what happened. Steve had taken you both to a friend’s house. Sam Wilson’s house. They had stayed there the night and Tony Stark sent a quinjet for them the following morning, Natasha in the cockpit. 

They planned how to take down Hydra and Tony made a cryostasis chamber for Bucky because while you and Steve were certain he wouldn’t hurt either of you, he did not trust himself. He went into the chamber and the rest of you took down Hydra. 

You had done more than you were supposed to and it had pissed off Steve, but you had simply rolled your eyes at him and told him to fuck off. He still hated your guts. So you kept away while Bucky was frozen.

You had officially moved into the tower, Tony had given you a room on Steve's floor. But it was easy to avoid him when he was avoiding you. 

You spent most of your time with Natasha or Tony, helping him as he figured out a way to get rid of Bucky’s mind control. It took him two months and you had been on a mission when he made a breakthrough.

Tony sent word that he was going to wake Bucky and he didn’t say but you knew he wasn’t waiting for you to return because Steve had told him not to. So you finished up and showed up to the tower, blood dry on your tactical suit, a cut hastily wrapped up on your leg, your eyes set on a glare as Steve intercepted you.

“You’re hurt,” he had stated, eyes on the bloodied bandage on your leg.

“Yeah, I had to speed things up a little,” you gritted out.

“You could’ve compromised yourself or the mission,” he had scolded.

Your blood boiled and you punched him on his perfect jaw, pushing past him to get to Bucky, but he recovered quickly and hauled you back by your wrist.

“You’re not going in there like that,” he said firmly. “Go wash up first. You’re going to upset him.”

You had yanked your arm free and walked off, ignoring Tony and Natasha as you headed to your room. You showered and you packed your stuff hastily. You carried the bag, not answering Natasha’s questions as you dropped it outside the room Bucky was in on the medical floor. 

The way he called your name when you entered made your heart clench. You didn’t look Steve’s way as you walked into the room, but you could feel his gaze following you as Bucky patted his bed. 

You sat down and bent down to kiss him. He kissed you back softly and when you pulled away he kept his forehead pressed on yours. “It’s gone. They can never use me against you. I won’t ever hurt you.”

“You would never hurt me,” she said, caressing his cheek. 

“Steve says we’re on the same floor,” he said. “We can take it slow if you want. I know we already mated, but you haven’t marked me yet and Steve—“

“Bucky,” you interrupted him with a soft kiss. “I’m moving out of the tower.” 

Bucky stiffened, looking at you with wide, incredulous eyes. “Why? It’s safer for you to stay here, with your mates—“

“It’s better this way,” you tried to reason. “You and Steve have history. I just got in the way.”

Bucky shook his head. “You’re not in the way. You’re our mate. We can take it as slow as you want. If living in the same floor is too much—“

“I’ll visit you often,” you said, voice strained because he looked so desperate trying to convince you. 

He sat up straight, hands grabbing onto yours. “Don’t leave, please.”

Your eyes filled with tears but you blinked them away. “You and Steve can pick up where you left off. I will visit you as often as I can. You’re my alpha, I can’t stay away.”

“What about Steve?” He asked. You averted your gaze. “Steve?”

The other alpha stayed silent and the silence was enough for Bucky to understand. His grip on you tightened, not enough to hurt but you could feel the anger rolling off him.

“Steve,” he gritted out. “Tell her not to leave.”

The alphas stared at each other for a second until Steve spoke. “Don’t go. It’s safer if you stay here. We still haven’t tracked everyone who was Hydra. They might go after you.”

“You’re staying here with us,” said Bucky. It wasn’t an order, it was a plea.

You stayed for Bucky and Steve continued not to acknowledge you as his mate. Bucky was still recovering, and wanting to help him was the only thing you agreed on. You took turns staying with him after a gruesome nightmare. The two of you quickly learned what he needed. Sometimes he needed Steve and sometimes he needed you. 

Sometimes he would stay holed up in his room all day and only allowed Steve inside. Sometimes you would find him on the couch in the middle of the night and he would melt into your embrace. You would hold him all night until he fell asleep, fingers running through his hair. You would watch over him all night and when Steve would wake up for his morning run he would stop to look at Bucky, but whenever your eyes met he would turn away and leave. 

The nightmares started to become less frequent and Bucky started falling asleep in your bed or Steve’s. It was as if he was splitting himself between his mates. He told you stories about Steve and himself. You learned that before the serum, Steve was an omega. Bucky told you whatever he could remember, because his memories about the past were still coming back slowly to him. 

You knew why he was telling you those stories, but you didn’t seek Steve out. The two of you became more cordial with each other, for Bucky’s sake. But you were not going to approach him any other way. He had been the one to reject you and he clearly still didn’t want anything to do with you. 

You told yourself that you didn’t care, but your soul and body longed for him. There had been times when you saw him and Bucky kissing and you longed to be with the two of them. You wanted your two alphas but only one wanted you.

Even now during your heat. Steve had left. He was your alpha but he didn’t want to be with you. Steve had left the moment your scent alerted him you were in pre-heat. 

With your hormones all over the place, you couldn’t even pretend that you didn’t care. He had left his laundry basket in the laundry room and you had used his clothes for your nest. Bucky had given you the privacy you needed along with his clothes until your nest was ready. Your nest was a mix of Steve and Bucky and you. 

The shirt you wore was Steve’s but his scent was starting to fade from your sweat and how many times Bucky had fucked you in it. His knot was still inside you, satisfying your libido and giving room for your hormones to turn against you. 

“He doesn’t want me,” you cried into Bucky’s chest.

“Yes he does,” Bucky said, his voice soft and comforting, pressing another kiss to the top of your head. “He’s just an idiot.”

“I need him,” you cried. “It hurts, Bucky. It hurts here. It hurts that he hates me.”

Bucky pressed his palm over yours where you clutched your chest. “Steve doesn’t hate you, doll. I promise you that.”

You shook your head and buried your face on the crook of his neck, inhaling his calming scent for comfort. 

…

Slick damped the sheets when you woke up with a needy whine that turned into a stuttered cry when you didn’t find your alpha next to you. “Bucky?” 

There was no reply from the open bathroom. You pressed your face to the pillow, taking his scent of cinnamon and sandalwood. You called out to him with a needy cry, but it was muffled by the pillow. 

The sound of loud yelling startled you. With a gasp, you untangled yourself from the sheets and climbed out of your nest, wearing nothing other than Steve’s shirt. Slick ran down your thighs as you stumbled out of your bedroom, tears slipping down your cheeks as you reacted in distress at the sour, angry scent in the air. 

“Alpha?” You called, finding them both in the kitchen. 

Steve inhaled sharply and took a staggering step back, eyes skimming down your body, throat bobbing as more slick ran down your thighs. 

“Go back to your nest,” Bucky said, blocking Steve, but you had already seen the blood on his nose. “I’ll be there in a minute, doll.”

“Alphas,” you whimpered, calling out to both. 

You heard the hitch of Steve’s breath but when you took a step forward he turned away to leave. You let out a hurt sob and he froze in place as Bucky ran to hold you in his arms as your legs gave out. 

You sobbed on the crook of his neck and he released calming pheromones to try soothing your distress. And while you always felt comforted by Bucky’s scent and the warmth of his body, you were inconsolable. You held his shirt tightly, body shaking with your sobs. 

Then there was a third palm on your back and your body arched toward the touch, recognizing your mate. “Don’t cry,” he choked. “Please don’t cry.”

Bucky let out a warning growl that resonated in his chest. “Don’t touch her if you’re not going to stay.”

“Bucky,” Steve’s voice was a plea. “I can’t stay. Not when she’s like this.”

“She needs you,” Bucky snarled. 

“She’s in heat,” Steve argued. “I will talk to her when it’s over.”

“Leave,” Bucky growled. “Now.”

Steve retracted his palm but it was quickly replaced by a warm material draped over you. Bucky stood up with you in his arms and you clutched the flannel tightly, inhaling Steve’s scent. 

Bucky took you back to your bedroom and set you down on your nest, climbing over you.  He spoke to you in a soothing voice, nudging your neck to the side to get to your scent gland. He licked over his mating bite, the gesture instantly making you feel safe and wanted.

“I need you,” you whimpered, wrapping your legs around his waist. “Bucky, please.”

“I’m here, doll,” he said, pressing his lips over yours.

His palms trailed down your sides, hitching Steve’s shirt up to expose your body. He nudged your legs open and pulled his joggers down to free his length. He pressed the head against your slicked folds and pushed his hot length inside.

You moaned into his mouth, needingly arching your body towards his. Bucky pulled his mouth away from yours to pull his shirt over his head. You clutched Steve’s flannel tightly as Bucky started thrusting into you. 

“You’re so perfect for me, omega,” he praised, drawing out a choked mewl from you. “You feel so good around my cock.”

“Alpha,” you cried, moving your hips in rhythm with his thrusts. “Harder please, please, alpha. I need you.”

Bucky grabbed your hands and pressed them over your head as he pressed his body down over yours, hips flushed to yours, his cock reaching deep inside you as he fucked you fast and hard. 

“So pretty, doll,” he said over your neck, sucking a mark over your neck. “So fucking pretty for your alpha.”

His praise made your clit throb and a whine slip past your lips. “I wanna be good for you alpha.”

“You already are,” he said, licking a stripe over your gland. “So good for your alpha.”

His hips snapped at a deliciously brutal speed, drawing out moans and mewls from you and sending sparks of pleasure through your nerve endings, heat pooling at your belly. 

“Your breasts are so pretty, doll,” he said as he pressed kisses down your chest. “So pretty and full for your alpha.”

“Full,” you blabbed, pressing your hand to your pelvis. “You’re filling me up alpha.”

“Fuck,” Bucky groaned. “You’re gonna make me spill, baby doll.”

“Please, please fill me up alpha,” you gasped as he dragged his teeth over your nipple. 

“Mm gonna knot you omega,” he said. “Gonna fill you up again until my seed takes root. You want a pup, doll?”

You let out a loud moan at his words. “Yes, yes, please alpha. Give me a baby. Fill me up.” 

You went pilant under him as he fucked you, hard and fast and so good. You were on birth control, you both knew that, but the idea of him fucking a baby into you sent you over the edge. You came on his cock, your walls tightening around his hot length, his name falling out of your lips like a plea.

Bucky thrust his cock sloppily as his knot caught on your opening. He kept fucking you until it tied you both together and he pumped his cum inside you, making you feel warm and full. 

The alpha licked the healed scar of his mating mark over your neck and lifted you up to roll you over so you were on top of him. 

“So perfect,” he mumbled over your forehead as you fell asleep, tears slipping past your closing eyes.
