Hey guys, I'm new to this fandom and this is my first Captain America fic which is basically my tribute to Steve Rogers' mouth-watering muscles and Natasha Romanoff's eye-bulging sexiness. A pure Romanogers fantasy for all the crazy stupid fans like me who ship these two hard 😘!

Nothing lasts forever...

Steve's eyes began fluttering behind the lashes again. Those echoing memories had surrounded him again. Tony, Thor, Sam, Bruce, James, Vision and Wanda...they all scarcely bothered him except that one familiar face...it hadn't left him alone since he returned to his time. Natasha...

Nothing lasts forever. The words were an irony in themselves. His mind, his body, his soul knows that she's gone forever, like she always said, but her reminiscences are always wandering in the dark corners of his mind and flood his dreams at night.

There was a lot of buzz around here...finding you in the ice...

He let out a shuddering sigh. He could never forget that day. It was their first meeting, the first day of a start. Their relationship began that day. Her face, her attitude, her courage...they always reminded him of Peggy. She was the first face Steve couldn't take his eyes off in the past ninety four years of his life. As the workers for SHIELD or the loyal members of "Avengers", you were both completely fine as long as you were in the battle field but at the end of the day...just friends or something more than that, you guys could never decided what it exactly was between you two. At least she couldn't.

Public displays of affection make people very uncomfortable...

A weak smile crossed his sweaty face. He still remembered the kiss they had shared on that escalator. The lingering taste of raspberry always sweetened his mouth whenever he recollected that sudden invasion of her lips. She pretended to be quite comfortable doing it, but it was her who was left more uncomfortable once it ended. Maybe that was why she would always try to be quite unaffected about the whole friend thing and fix him with any girl she saw, but he never looked at 'em the way he did at her. Even Sharone could never compete with her in his eyes. And it was not just a physical attraction they felt toward each other every day. At the end of the whole "Winter Soldier" mess, seeing Natasha go away from him made Steve feel a bunch of emotions he had only felt for Peggy once.

Well, it's not like we ever had a place in the world...

He turned his neck to the side and buried his face into the pillow as another puzzling set of words echoed in his brain. He could never understand why Nat said those words that day when the team was in the middle of a catastrophe. Why did she feel like we didn't have a place in the world? We were the great Avengers for God's sake! We had millions of fans all over the world! It was more about her than us, that he was sure of. Before Steve could tell her about these new feelings he was feeling for her, She had officially admitted her feelings to Dr. Banner and in spite of Steve's unreasonable jealousy, he respected her decision, although he knew their relationship would never get the happy ending she deserved. Maybe Dr. Banner's constant rejection made her feel that she wasn't made for a "normal" life like any other woman of this world?

Because I didn't want you to be alone...

His feet were fighting the blankets as that smiling redhead flashed before his eyes again. Her words caused a deep ache in his chest. THAT was what he had always admired about Natasha! No matter what happened, she always stood up for her friends. She was professional, knew and understood SHIELD's way of working, but still took the right decision when the time came. She was the only one Steve could never be against in their battle. She had chosen Tony's side in Avengers' personal "Civil War", but she allowed him and Bucky to escape during their fight because she knew he was right. That was what he made Steve fall for her even harder.

Well, then we have to protect it...

His right hand unconsciously reached up to wipe the sweat off his forehead. Another ghost flared before his irises. That woman was the first one that came forward to fight Thanos. Natasha even opposed Bruce's decision to avoid fighting that purple monster because she knew how much Vision meant for Wanda. The girl was like a little sister to Nat and for a woman who had lost her family at such a small age, it was almost like a responsibility for her to save her sister's love. Something Steve had never seen anyone else do so unselfishly. His love and respect for Natasha had doubled that day.

Even if there's a small chance that we can undo this, I mean, we owe it to everyone who is not in this room, to try...

Steve arched his back with a shaky exhale. They had been defeated. Half of Earth's population was gone and they had lost some very valuable friends. Bucky, T'Challa, Peter...everyone had turned to dust right before their damned eyes but they couldn't do anything to save them. They desperately needed a hope to bring everyone back to life and they got that one hope as the Garden, the place where that fucking Titan was resting after destroying the whole universe! When Steve doubted his own strength and faith, it was only Natasha who made him believe that they could beat Thanos this time.

This is gonna work, Steve...

But unfortunately, the plan didn't work. They finally dug out Thanos, who was now resting on an otherwise uninhabited planet and tried to retake and use the Infinity Stones to reverse the disintegrations as we planned, but that dying demon revealed that he had already destroyed them to prevent further use. An enraged Thor decapitated Thanos, but that was not going to bring everyone back. They returned empty-handed. Years later, they got another hope as Quantum Realm, a dimension that could allow time travel. It was their last and only chance to go back in time and retrieve the Stones from the past to reverse Thanos' actions in the present. The machine was built, and Everybody was given their respective tasks. Steve still remembered the night before they were about to leave. Natasha was standing in the balcony of her room, looking up at the starry sky. After a small talk, Steve jokingly asked her what she would do if she ever got a chance to use the machine just for herself and her reply was something he had never heard from her mouth before.

I would just go back in time and get on that Quinjet with Bruce, because everybody should be with the ones they love and who love them back...

But that could never happen. She had to sacrifice her life to achieve the soul stone. She could never get a chance to live her dream. With the end of the war, they had lost two big faces. Tony and Natasha. Tony received the grand funeral he deserved, but Nat..she always tried to live like a ghost among the people. She saved the world everyday, but didn't want to take the credit. Her self-sacrifice earned no esteem, because that's how she wanted it to be. After everything was over, Steve was given the responsibility to return the Infinity Stones and Mjolnir to their original places in time. After accomplishing the task, Steve looked down at the remaining particles in his hand. Taking her last advice, he finally decided to be a little selfish and go back in time and live his life with the woman he loved. Of course it was Natasha now, but she never loved him back. Steve was nothing but a friend and co-worker. It had always been just Bruce...

And for him it was her. His Natasha.

His Nat.

"Steve?"

Steve's eyes fluttered open as Peggy's sleepy voice fell into his ears. Gasping heavily, he looked down at his lovely wife in his arms and smiled weakly. "Hey..."

"Hey." Peggy smiled back sympathetically, cupping his cheek. "Another nightmare?"

He let out a deep sigh, shaking his head. "No. It was just a bunch of old memories."

"You whispered a name this time." she spoke softly, her eyes searching his. "It was Nat."

He gulped nervously as Natasha's pet name whispered out of Peggy's mouth. He had never discussed his 21st century's life with Peggy since he returned to her. Luckily, his nightmares didn't reveal anything, either. He wanted that part of his life to stay buried in a dark corner of mind, but a small fragment crawled its way out of the ground anyway.

He tossed his head back and gathered Peggy in his arms before muttering. "It was just an old friend."

Peggy played her head on his now calmly beating heart. "Wanna talk about him...or her?"

Steve smirked weakly and shook his head. "No. She needs to remain undiscussed, darling."

That was how she was going to be now. She was one of the unforgettable aspects of his past and he was going to keep her that way. He returned to Peggy just because she was the only woman who had ever bothered to love him, but that didn't mean he had forgotten the woman who had almost taken Peggy's place in his life.

His Natasha, his Nat was going to be in his dreams, forever.
