Accidentally on purpose

Chapter 3

Do you like my cookies? They're made just for you.

A little bit of sugar, but lots of poison too.

The morning Steve had left Natasha's apartment to run home to his girlfriend, Natasha made the decision to stay away from Steve for a while. She didn't trust herself anymore, especially not while being around Steve. She simply felt awful for what she had done but decided to put that far away in the back of her head and focus on more important things. Important things being her job. There was only one problem in that though. A certain super soldier worked at the same place and not only the same place, but as her partner. Natasha and Steve had been assigned as partners years ago which is one of the reasons to why they became close friends. They've saved each other's lives countless of times and fought alongside each other so long that they pretty much knew exactly how the other one fought and protected themselves. If Steve had been a book, then Natasha would have read it over 100 times by now. There wasn't many things she didn't know about him, and he knew too much about her as well. Enough to be able to hurt her at least, and not many people had the power to do that.

Staying away from Steve was therefore not as easy as Natasha wished, or not wished. She was a bit confused over what she actually wanted, except for Steve's touch and Steve's lips, because that was something she couldn't keep her mind off. Even during missions when she was meant to focus on what to do, her mind always travelled somewhere else. Natasha did however manage to keep her distance from Steve as much as possible. There was however one mission that ruined it all. It was a pretty simple one. Take out a few bad guys, get some information, then leave. Nothing they hadn't done before. Natasha was fighting a few men that obviously didn't stand a chance against her, but Natasha's mind was somewhere else and she simply didn't realise the two men approaching behind her. Steve ran up to her just in time and protected both of them with his shield as bullets started firing their way. Natasha quickly pulled her gun, firing back as Steve dragged her with him behind the shield. Steve pinned Natasha against a wall of a back building as he slowly peeked out to see if the men was approaching them, but both of them had fallen to the ground by Natasha's bullets. "It's fine. I had them." Natasha said, trying to ignore the tension between them as Steve stood so close. "Yeah, right." Steve said, looking at her. One of Steve's hands still grabbed tightly around Natasha's arm as she was still pressed against the stone wall. Natasha's eyes tried to focus on anything else but on Steve's while his eyes desperately searched for hers. Once Natasha's green eyes met Steve's blue, they knew they were screwed. Steve dropped his shield to the ground as he basically attacked Natasha's lips. She kissed him back, wrapping her arms around him, pressing him closer. This time, neither of them interrupted it all to say that it was wrong or that they should stop. Simply because it didn't feel wrong and because they didn't want to stop. Therefore, they simply continued the act. Steve's hands travelled tightly over Natasha's cat suit, desperately wanting to feel the skin under it as she wanted just the same. They didn't actually stop until Natasha realised that they were on a mission and that this was extremely unprofessional, and Natasha didn't do unprofessional. She pushed away Steve a bit, gave him a glance before hurrying away to finish the mission. Steve grabbed his shield before following her.

After that mission, they simply couldn't resist each other even though they both really tried. Both of them kept their distance but managed to bump into each other everywhere. It was as if God was playing them a prank. Natasha had been attending a few meetings and simply waited for the elevator to arrive at her floor. As it did and as the doors opened, a quiet "shit" slipped between her lips as she saw Steve in front of her. He raised his eyebrows, surprised to see her. "Rogers." She said, before walking inside, standing a few feet away from him. "Romanoff." He answered and Natasha pressed the button to take her to the right floor. It didn't take long until there was no space between the two of them at all. Natasha simply pressed the stop button, giving her lots of time to make sure that the first time Steve ever had sex in an elevator would be amazing. Which it was, of course. It also gave the man responsible over the security tapes quite a shock as he looked through them later that day. Steve and Natasha may be many things, but careful wasn't one of them.

This is how it continued for weeks. Natasha went earlier than usual to the training hall in the Avengers facility to work out before anyone else arrived, only to meet Steve there which ended in a whole lot of steamy kisses and shower sex. They even met while Steve was out running only to see Natasha pass by on the other side of the street. Once, they even bumped into each other in the grocery store even though they live pretty far away from each other with different grocery stores closer to their apartments. It all almost seemed ridiculously convenient. Steve felt awfully bad and ashamed of himself each time he had been with Natasha. He loved Sharon a lot. He didn't want to hurt her nor be unfaithful to her. But there was something about that spy that drove him crazy. Something that made him long for more and more. It was never enough. He also loved the excitement and the new world that Natasha opened up for him. The desire and deep attraction to just have Natasha right there and then had never occurred between him and Sharon. There was so much passion between Natasha and Steve. More than either of them was used to, and definitely more than they were used to handle.

All Steve's regret and feelings of shame always disappeared whenever he was with Natasha. As soon as he saw her, it all disappeared and she was the only thing on his mind. Her red hair, beautiful green eyes and stunning body. After so many times of occasional meetings and unplanned steamy moments, they soon became planned. "Hey there, soldier." Natasha said when Steve stood in the doorway to her apartment. He gave her a boyish grin and Natasha raised an eyebrow. "Hey beautiful." Steve answered, forcing out a smile on Natasha's lips before she jumped up in his embrace. Steve wrapped his arms tightly around her, kissing her passionately. Natasha's hands went up in Steve's hair and around his neck, making sure the kisses didn't stop. Her legs wrapped around his waist and Steve closed the door after him before focusing on the redheads deep kisses. As usual, they ended up naked and sweaty in Natasha's bed after exploring each other's bodies as much and long as possible. Steve kissed Natasha's lower lip before his lips travelled down her cheek to her neck. Steve continued placing small kissed between her breasts and down to her stomach as his big hands were holding her waist. "I love this." Steve murmured against her soft skin. Natasha smiled a bit as she looked at him. "You need to get going, or you'll be late." Natasha said, hearing a small groan from Steve. His lips soon found Natasha's again and she kissed him back hard and deep. She wasn't sure why, but she wanted her kisses to be on his mind. Natasha wasn't really overjoyed by the fact that Steve was going home to his girlfriend, which made her sort of selfish. She was after all the one doing the wrong thing, not Sharon. Still, she wanted Steve to remember her kisses though she wasn't sure why. Steve got dressed and Natasha grabbed one of her silk robes, putting it on. She then followed Steve to the door. "I'll miss you." Steve said and Natasha gave him a small smile before kissing him one last time. She made sure to make it deep and passionate, twisting her tongue with his and leaving Steve's mind a little dizzy as she pulled away. "Bye, soldier." She grinned and Steve smiled back at her before leaving her apartment.

As Steve walked into his and Sharon's apartment, it was clear to Sharon that Steve's mind was somewhere else. She smiled at him. "You're early." She said and Steve looked up at her almost as if he had forgotten she lived there too. "Busy at work today?" Sharon asked and Steve nodded, embracing her in a hug. "Yeah, like always." He said and Sharon nodded. "How was your day?" Steve asked softly with his arms around Sharon's waist. "Busy." She answered, her hands cupping his cheeks. "What do you say about us skipping dinner and do something else today?" She said, giving him a few soft kisses. "It's been a while after all.." She mumbled against Steve's lips. Steve hesitated a little, but knew she was right. Well, it had been a while for her, not for him. So he did what anyone would had done, he wrapped her closer and kissed her deeper. Though while he did that, he became a little frustrated. While kissing Sharon's lips, he simply couldn't help but imagine how different it felt kissing Natasha's lips.
