If it was for a mission would she understand?

If his lips touched another because he was trying to save not only his life but the lives of so many other people? Would she understand?

All these thoughts were running wild in his mind as Steve Rogers came home to his wife, spy herself, Natasha Roman- no it's Rogers now. Steve was constantly telling people that especially to men who come up to Natasha a party. So he knew what it's like to be jealous.

He felt horrible for his actions, but peoples' lives were at stake. His life was too. With Natasha expecting their first little wonder in the world he couldn't leave them. She needed him to come home, and he did. they were able to apprehend the suspect, who did indeed have a bomb, and two guns in possession. He was heading toward the mayor, who was with a family of his own. Steve had to do.

Getting down to how it actually happens doesn't matter. The opportunity arose to catch this guy but someone was about to recognize Steve so he had to do what was best before the suspect started opening fire.

He knows it was all for the mission, but a part of him feels horrible. So when he comes home late the night and saw Natasha laying on her side looking tiredly at the wall he felt horrible.

"Hi, baby." He said gently. She looked up and him and smiled. He walked over to her and laid down gently moving his arms around her waist taking in her scent.

"What's wrong Steve?" She asked when he was too quiet. Usually, he asked how her day went, if the baby was okay, did she need anything. She wasn't feeling needy but she knew that it relaxed Steve when she was relaxed.

"Natasha I love you."

"I love you two," She said and turned over so she could face her husband.

"No like I am in love with you like I would never purposely do anything to hurt you," He was looking at her with such love and regret in her eyes she had to sit up. She was eight months pregnant, so with a big belly, Steve had to gently place his hand at her back to help her sit up.

"What are you rambling on about now?" She asked pulling the covers up to her chest. Steve couldn't get the words out, it was like they were poison on his lips. "Did something happen on the mission."

"There was no other way, just know that. I tried to think of a way out but nothing was presenting itself and I'm sorry." He started to ramble, and only stopped when Natasha's hand rubbed his.

"Steve just takes a deep breath before you pass out," She said.

"I just don't want to hurt you." Now she was giving him a very confused look.

"Can you just say it before I pass out? It's been a long day and this baby has been kicking-"

"Natasha I cheated on you."

It was finally out. Now the room was nothing but silent, as Natasha fell straight from her words. She could only look at him as if processing all of his words. Nothing made sense.

She wasn't speaking, and what was Steve expecting? For her to immediately be forgiving and telling him it all for the mission? He should have known. He should have listened to Sam 'she's gonna be pissed.'

"Technically speaking," He said breaking the silence.

"Technically?" She asked looking up at him with disgust in her eyes. It hurt worse than any bullet wound. "What the hell does that mean?"

"Means that it happened on a mission, so it didn't mean anything and didn't count." He was rambling, only making matters worse for him.

"Oh so because it happened on a mission means it didn't count?" She asked with disbelief in her voice and look. She tore her frosty glare away from him slowly removing herself from the comfort of their bed.

"That's not what I meant, what I meant to say is that it didn't want to and technically I didn't mean to, but for the safety of my team and me, it was the only option." Still not helping.

"And that makes it okay?" She asked. "Who was it? Who did you kiss?" Steve didn't answer. "It was the pretty little blond wasn't it?"

"Natasha-"

"Oh my- it was!" She gapped. "Of course it was Sharon!"

Sharon is a very touchy subject because they dated for a little bit before Natasha and he got together. Natasha almost tried to push him to Sharon because she didn't have her scars. Steve knew that deep down Natasha was jealous of Sharon.

"I promise you it was just a kiss-"

"Just a kiss?" She frowned. "so kisses now are 'just a kiss?' When you kiss me it's just a kiss?"

"Of course not!" He quickly said, he had to calm down, he didn't want to stress Natasha out.

"This is so unbelievable." She muttered.

"I love you." He repeated. "God I love you so much and nothing will ever change that."

"I would feel special but I know you have told that to Sharon." he did because at the time he thought Sharon was the one, but that was before he realized that the feelings he had for Natasha could never fade away.

"I mean what I said. I did for you, so I could come back to you and our baby-"

"Oh I am so glad you thought about us as you made out with Carter." she rolled her eyes. "I trust you!"

"And I hold that trust with everything that I am Nat, you are my everything. If you want to be mad at me than be mad at me. If you want to yell at me, then yell at me. But just know I can never stop loving you, you are the only person to make me feel like I am more than just Captain America, that Steve Rogers was enough." he sighed and took a step forward. "If I had any feelings for Sharon I wouldn't be here with you, with our baby."

There was a silence for a little bit. Natasha was upset but she didn't know what caused her to lose control like this, she trusted Steve. If he says it was for a mission than she is gonna believe him.

"I am sorry." She said taking that final step to be in his arms once again. "I don't know why I got so mad, I just freaked out and-"

"Hey don't do that. It was my fault. I shouldn't have done it, but since it did happen I knew you had to know about it. But know I love you. I wouldn't want anyone else but you," His hand goes onto her very pregnant belly. "I love you."

"I love you." She smiled and placed her head on his chest. The two stood in each other's arms in complete silence for a few moments before Natasha spoke up. "But if you ever kiss another woman I will murder you in cold blood understood?"

"Understood."

As much as they would have liked for this horror to be over, it was not.

The next day Steve left early to do some paperwork at his office, and Natasha thought she would go down to see him. They lived on the Avengers facility so it wasn't much work for her to walk down. However when you are nine months pregnant you need to take a seat, the only available bench was behind a bush.

"They are totally secretly dating," She heard the voices of two of the agents who were walking through the facility. They must have not seen Natasha.

"You are insane," Another responded. "There is no way it's happening. He is a married man, and to be honest, his wife is so scary that he wouldn't even think about it."

"He's Captain America, he probably not even afraid of her," The first girl laughed. "Besides Captain Rogers and Agent, 13 look so cute together."

"I wouldn't let Agent Romanoff hear you say that I heard she can kill someone in two seconds." Yeah, she could, and she could do it nine months pregnant.

"It doesn't matter. I heard he and Sharon are having lunch together, and if they weren't dating why is he here with her instead of Romanoff?"

"Agent Romanoff is pregnant and Captain Rogers is a good man, he wouldn't do that. You are gonna spread rumors."

"I'm just spitting the hard truth." The two agents had walked away at this point. Natasha was speechless. He wasn't with Sharon. Was he? Before she could continue to think her feet were taking her to Steve's office.

"Mrs. Rogers." His assistant smiled. Steve never wanted an assistant but Tony insisted. She adored Natasha and seemed to be the only one, besides her close friends, who called her by Rogers and not Romanoff.

"Hi, Olivia." She smiled. Olvia was a younger and new agent, Hill believed she needed responsibility before she could start in the failed, so Tony gave her desk duty with Steve. "Would you like me to inform your husband that you are here?"

"No," she held up a bag. "I came to surprise him." And now to see if he was with carter.

"Well I am sure he will be thankful, he is actually with someone at the moment,"

"But never too busy for his wife." She said and then walked over to his office stopping Olivia from saying anything else. She opened the door and saw Carter sitting on his desk looking down at the papers he was working on. A little too close for her liking. She raised an eyebrow at Steve. "Am I interrupting something?"

Steve looked up and he knew by the look on her face that he was once again in trouble.

"Of course not," Sharon said. "I was just leaving. Bye Steve."

"By Sharon." He said and then Natasha watched as Sharon left the room before turning to her husband.

"See you two are quite friendly now aren't you?" She said sharply. Steve sighed, he had a headache at the moment.

"What are you doing here? You should be at home resting." He said.

"So you can spend some alone time with her?" Natasha said bitterly.

"It's not what you think and I think that you should take a seat and relax. Too much stress is bad for the baby."

"Maybe if you weren't causing me stress."

"What do you want from me, Nat? To fire her from my team so she's not around me? Tell her to get lost when she comes to talk to me? Or would you prefer for me to straight-up fire her?" Before Natasha had a chance to yell back at him he continued on. "Because I will. I will do anything for you. If you want me to stop being around her because it makes you mad or uncomfortable say the words because I will."

She was speechless. She was not expecting this to come out of his mouth.

"I will." He repeated. "But please know that I would never cheat on you. How could I cheat on someone who already the best human in the world? Someone, who I get excited to see when we are only apart for an hour? Someone who is about to have our baby? I would never do that to you or this baby." He put his hands on her stomach.

"I never meant to question your loyalty, Steve. I am just scared. Scared that one day you realize you could do better, that you could-"

"There is no one better than you. You are my world. My soul mate. I know why I had to sleep for 75 years, it was to meet you. I would gladly do it again if you asked, as long as I get to see you."

"I am sorry," A tear left her eye.

"Don't be. I am sorry for making you ever doubt yourself. Natasha if I wanted to cheat on you, I wouldn't have married you. You deserve the world and for the rest of your life, I will work to give you that. But I need you to trust me. Do you trust me?"

"I trust you." She said. "I love you and I don't deserve you."

"Yes, you do. I don't deserve you," Steve replied. "God I am sorry if I caused you pain." Before he could fall into a rant Natasha stopped him.

"No don't do that. It wasn't your fault. It was my own insecurities. I love you so god damn much Steve."

"I love you."

"I love you more."

"I love you the most."

And if it was possible, the two fell even more into love that day.

Was this just cheesy and bad? Please let me know!
