At 6:00pm sharp there was a knock on Steve Rogers door. He gazed at through the peephole to confirm his suspicions and standing there in jeans, tank top and hoodie was Natasha Romanoff.

Unlatching the door he swung the door open and didn't even have a chance to welcome her before she sauntered in. She carefully eyed his apartment before dropping her handbag and perching on the edge of the armrest of his couch.

"Make yourself at home." He criticized.

"Now, Now Cap. Is that any way to talk to your guests?" Natasha chastised as she removed her hoodie and placed it on the couch behind her.

"If the guest is properly invited in then no... and what did you just call me, Romanoff?" He argued.

"Cap... short for Captain... short for Captain America. This isn't a mission, we don't need to address each other by last names." She explained.

"I'm not going to be called "Cap" by you, Romanoff." Steve declared.

"I thought I asked you to call me Natasha. I don't think you'd be comfortable with me calling you Steve. That seems a bit more like a close friend or dating kind of thing to me." She debated back.

"There is no winning this, is there?" He complained.

"No." She teased.

"Fine, Natasha. But your lesson had better be worth it." He frowned.

"Don't you trust me? Besides I think you'll quite enjoy our first lesson." Natasha purred.

"Which is...?"

"Kiss me." She commanded, her voice low and breathy.

"Excuse me?" He faltered.

"Kiss me. Kiss me like you will only get one kiss, a goodbye kiss." She clarified.

He looked confused and stayed by the door, his eyes drifting to the floor.

"What is it? What's the hold up, Cap?"

"I just thought that... that we would start by talking about how women are different and what they expect or something. I didn't expect to start out like this." He admitted, not looking up at her.

"Hey, come on. Don't be shy." Seeing his continued reluctance she started to lose her patience. "I've got to see what I have to work with. Physically and mentally. If you can't kiss me because you're nervous when you know I want you to then how are you going to go on a date when you aren't sure if she wants to kiss when you want to?"

Steve sighed softly to himself, defeated by her logic. His eyes locked onto hers and he straightened his back.

"Like it is the only kiss I'll ever get?" He asked.

She nodded , her eyes glued to his. He strode across the room and cupped her face, his eyes never leaving hers as he leaned forward and closed his eyes as his lips met hers. It was a kiss full of emotion: tenderness, sweetness and soul but mingled with bitter sadness and regret. Natasha closed her eyes to feel the full intensity of the moment.

When they finally broke apart, Natasha let out a soft breath. She was glad she was sitting as her knees felt shaky. It was a kiss unlike any she had ever experienced. So full of something sweeter and more meaningful than pure lust.

As Natasha slowly opened her eyes, Steve gazed into them, self conscious as she had yet to have any reaction. He could feel the slight flush of embarrassment sweep over his cheeks. It was only his third kiss in his whole life and he thought it was maybe his best, but what would he know?

"OK. I can work with that." Natasha remarked breathlessly after a few moments pause.

"So ... it was OK?" He queried.

"Yes. It was OK. Good even." She reassured.

"So what now?" Steve asked.

"Kiss me again." Natasha answered.

Steve started to lean back into her slowly before her hand pushed gently on his chest. He stopped and looked at her confused at the contradiction between her words and actions.

"Not so fast, Cap. I know you can kiss gently but what about a bit more... passionately, lustfully?" she requested.

"Lustfully?"

"Yeah. I know that in the time you grew up you didn't really talk about or express that part of relationships. But nowadays we do. No only do we think about and talk about it but we act on it. Any modern woman is going to act on hers and expect you to do the same."

"Really? Women are that forward?" Steve wondered.

"Really. And I don't want you to be like a lamb to the slaughter. You're so... innocent that I'm not sure you'd survive. Now kiss me again."

"I'm not sure I know how. I mean where do I start?"

"Kiss me like..." Natasha paused trying to think of a way to explain without being vulgar. "Like you want to make love to me, right here and now. Like you cannot wait a moment longer."

"Natasha!" Steve cried out in shock.

"Shy, Cap? Then I guess I'd better start." And without another word she pulled him into her waiting lips.

Steve was shocked and resisted, overwhelmed by the intensity and passion that Natasha displayed. But she ran a hand through his hair and pressed herself closer to him. Steve opened his eyes and gasped in shock, allowing Natasha better access to his mouth. He could not resist such an attack, no man could.

Steve gave in to something he didn't even know was inside him until this moment. He wrapped his arms around her and lifted her off the arm rest of the couch before pulling them both onto the couch, lying side by side, her body pressed between him and the back of the couch.

She pulled away from him sharply. She smiled at him, impressed at his improvisation and actions but his kissing was still too timid, too submissive. She was still the driving force in that kiss. She needed him to want to kiss her with passion, to take the lead. She ran a hand through his hair, brushing a lock of it out of his eyes.

It was a divine torture that Steve had never experienced. She was so close to him, every part of her body pressed to him except her lips. He wanted to kiss her again, to feel her lips against his, to get lost in the feeling of passion that that kind of kiss inspired.

Natasha looked up at him, eyes defiant, challenging. Almost as if they said "If you want another kiss, come and get it." Steve needed no further invitation and closed the distance between their lips with a force and hunger that surprised Natasha. She hadn't expected it and the surprise made her gasp, before meeting Steve's passion.

She wanted to kiss him all night. There was a kind of innocence to his passion. It didn't feel like it did with others, overtly sexual and dominant, as if they were trying to force their will and selves upon her. It was just the right amount of dominance and passion tinged with lust. It was clear he was enjoying her, the feeling of their bodies intertwined but without the desperation to get her naked and underneath him.

When they broke from the kiss they looked into each others faces and Natasha giggled gently. Steve raised an eyebrow, enjoying the closeness, a closeness he had never experienced before.

"What?" He asked.

"It's just that I didn't expect this from you, Rogers. You seem so straight laced. It is surprising." She jested.

"You aren't the only one surprised. I've never felt or thought that..." He trailed off, unable to really complete his thoughts, his emotions jumbled up inside of him.

"Well now I know you can kiss with passion. But there are more types of kisses than that."

"Oh really?" Steve smiled.

"Really."

Natasha moved her lips closer to him, placing them on his. Sweet, gentle. Steve opened his lips and started to respond when she pulled away. He tried to kiss her lips but she pulled away again.

"Natasha." He whispered, his voice full of tenderness and need, trying to find her lips again.

Natasha turned her head so he couldn't reach her lips. She felt his forehead press into her shoulder. He rubbed against her shoulder gently. He knew she was teasing him and he wanted to kiss her, but he wasn't sure he could contain himself if it was only a peck.

He sighed and lifted his head off her shoulder. He looked down at her, the curve of her jaw, the smoothness of her skin and the silkiness of her hair. He wanted to kiss her again, to hold her and stay like that all night. The repressed sexuality within him made him crave her touch and kiss.

Natasha turned towards him and placed her lips on to his, slow, gentle. He moaned into her mouth but resisted the urge to force the kiss deeper.

"Very good, Captain Rogers. I see you are getting used to a teasing kiss." Natasha smiled.

Steve returned her smile and leaned forward, kissing her gently on her lips, stroking her face with one hand. He kissed her tenderly, passionately and just on the lips and she returned his actions. They kissed and kissed until the sun had set outside and the room had grown dark.

They would have kissed longer if not for the growl of Steve's stomach. They broke there kiss and Steve looked away, embarrassed, as Natasha glanced down and laughed.

"So I guess that is the end of the lesson today?" Natasha teased.

Steve didn't meet her eyes, displeased with her teasing and the feeling vulnerable. She always made a joke at his expense and it did irk him sometimes. Natasha, sensing his shift in mood reached up and kissed him briefly but tenderly.

He smiled and they both started to move, Natasha untangling herself from his arms as Steve swung his legs around to sit on the couch, leaning forward and breathing heavily. Natasha ran a hand down his spine as she lay on her side on the couch. Her touched caused him to breathe out rather heavily.

"You alright, Rogers?" Natasha asked.

"Yeah, I'm good."

"Just hungry?" Natasha joked.

Steve rolled his eyes and shook his head slightly. She was right about her having fun at his expense.

"Well I could use something to eat as well. Why don;t we go and grab some dinner?" She suggested.

"Dinner?"

"Yeah. I know there is a great Thai place around here and figure we could keep each other company."

"Alright. Let me get ready."

Steve rose and switched on the light, casting a quick peek over at Natasha. Her hair was messy, her lips slightly swollen and her face flushed. She sat upright on the couch and started to run her hands through her hair to neaten it.

"Bathroom?" She asked.

"There." Steve pointed as he headed to his room to find a jacket and shoes.

5 minutes later they were both ready and headed out the door.
