Natasha stormed up to her apartment, slamming the door behind her as she entered, her mind a whirl.

What the hell is he thinking? Going to kiss me outside of his apartment! That is not part of the lessons. I'm just his teacher not his girlfriend and I'm not going to be. Not his, not anyone's. She thought angrily to herself.

Natasha took a deep breath and calmed the fire inside. She couldn't be mad at him. She knew what he was, a gentleman and a virgin. It would only be natural for him to feel sentimental towards her.

And I never did make it clear about where the boundaries are. This is all my own doing and I need to contain the situation.

Natasha headed to the shower to wash the sweat of their lesson off her. A clean slate, undoing the the recent past between them.

Steve headed up to his apartment feeling as though he was carrying more weight than just his gym bag. It wasn't tiredness from the wrestling though it had been a good workout. No what was weighing on his mind was what just happened between them.

The way Natasha had turned away from him when he went to kiss her. Steve was confused. They had kissed many times and she had never acted so coldly to him before. In fact she had often welcomed or initiciated it.

But those were lessons on kissing. This was about touching and control. Steve thought. Natasha had gotten inside his head again, made him all confused. Right now he needed a distraction and he knew who to turn to.

An hour later Steve was sitting in a sports bar with Sam watching the game on TV. The bar was too noisy for much talk, the beer was cold and the teams where equally matched and displayed on large screens all around the bar. Perfect.

"Oh come on! How could you miss that!" Sam shouted from the stool next to him.

Steve took a swig of beer and smiled. At least some things never changed whether it was 1945 or 2015. After the game finished Sam realized how late it was and rushed off.

"Sorry, I gotta run man. Another big meeting early tomorrow then I gotta go head up north for a while. I'll hit you up when I'm back in town."

"Not a problem. Let me know if there is anything you need anything." Steve offered.

"No, I'm good man. You take care of yourself... And your mysterious lady." Sam added, heading off into the night.

Steve headed back to his place and checked his phone. No messages or calls. He wanted to call Natasha, to explain or apologize or something. He put his phone down and sighed. Steve knew Natasha well enough to know that she would have to be the one to call him and she would do it when she was ready and not a moment before. His calling her could only make matters worse not better. He laid down on his mattress unable to get comfortable on the too soft bed. It was going to be a long night.

Steve was up at 5:00am the next morning for his run, unable to stay in his house any longer. He completed his laps and was bored of running but it was too early for the boxing gym and he didn't want to go home. Then he remembered that there was a jujistu class on that morning at 7:00am. Checking his watch he saw he had enough time to make it.

The class was good. The instructor had shown them more positions, tranistions and a simple arm bar. Steve came out of class feeling elated from the endorphins coursing through him and famished at having exercised for three straight hours.

He grabbed breakfast in a nearby cafe and checked his phone. Still no calls or messages. Natasha must either be really mad or wanting to make him suffer.

"Get it together, Steve. Stop checking the phone and waiting for her to call." He chastised himself.

He kept himself busy. Laundry, watching movies Sam had recommended and listening to music from the 40's and 50's. And yet he couldn't stop looking at his phone or thinking about Natasha.

And not just the kissing. He wanted to know why she was avoiding him. Was it because he tried to kiss her? She had kissed his neck and cheek. Didn't that mean she wanted to kiss him? Or did that mean she didn't want to kiss? Women had always been confusing and modern women were even more so.

Steve was like this for three whole days. Running, boxing, BJJ classes, movies, music, reading and internet. But above all trying to guess what was going on with Natasha. She was upset, he could guess that much. But was it because of what he did or she thought he had thought there was more than there really was?

His phone beeped and Steve practically pounced on it. It was from Natasha.

I'll be at yours at 6:00pm.

Steve's heart hammered and his stomach dropped. He would see her tonight. Lord only knows what would happen and he was both eager and dreading to find out.

Natasha was punctual, of course. Steve looked through the spyhole to gauge what he was in for. Natasha looked beautiful as always but also very determined. Taking a deep breath he opened the door.

"Natasha."

"Rogers."

Silence. He wasn't sure what to do. She was.

"Aren't you going to invite me in?" She asked.

"Only of you want me to, Ma'am." He replied.

She nodded and Steve opened the door wider, allowing her access. She walked in with long soft strides and stood at the end of the hall instead of going into the lounge as she usually did. Steve noticed this and was sure it was a bad sign.

Natasha waited until he had shut the door before speaking.

"Rogers, why am I here?" Natasha questioned sharply.

"I am not sure."

"Then let me make myself understood. I am here as a teacher only to instruct you in the ways of modern dating. What I teach you here in your apartment stays here."

"Natasha you aren't just my teacher. You're my friend."

"That is true and when we are outside of this apartment you will act like it. We are nothing more. You do not kiss me, hold my hand or anything that can be construed as romantic. Are we clear?" She finished, her voice hard.

"Loud and clear, Ma'am." Steve assured her.

"Good. Now lets get today's lesson underway."

Natasha grabbed his hand and dragged him into the lounge room. She pushed him onto the couch and he sat heavily.

"Natasha what are you mmm.."

The rest of it was cut off by her lips capturing his, her hands holding his face. She was forceful and dominant, and she straddled his lap. Steve tried to break away from her but she held him too tightly. She pressed herself close to him and he could feel every part of her, especially her chest. Steve moaned into the kiss. Suddenly she pulled her lips from his and started to kiss and nibble his neck and ears.

"Natasha.. wait I.."

"I won't leave a a mark this time, Cap." She purred into his ear, her free hand running down his chest.

Steve relaxed and she resumed her sensors attack on his neck, her hands pinning his biceps to the couch. Natasha was in control and that was how she wanted it to stay. Steve groaned from the pleasure of it and almost lost his mind when Natasha started to rock her hips back and forth.

"Natasha! Oh God!" He panted, his breath quickening, closing his eyes. "Oh... Uhhh!"

Natasha abruptly slid off his lap and sat next to him on the couch. Steve opened his eyes and glanced at her.

"Natasha... don't stop. It feels good."

"Really good?" She questioned.

"Yes." He replied breathing heavily.

"Almost too good?" She pressed.

"I... I guess? Natasha, please?" He pleaded, his bright blue eyes intense with passion and lust.

"I can't, Cap. That's today's lesson. Keeping control, having a way to cool off, a safety valve if you will."

"What? Why?"

"Because if i keep going..." Natasha paused and ran a hand up the outside of his thigh to his hip. Steve bit down hard on his lip to contain himself.

"Then we won't be able to go on much longer." She finished with a smile, observing his reaction.

Steve sighed. She was probably right and at that moment it felt as if there was a fire raging through him, all consuming. He wanted to pull Natasha onto his lap, to continue moving their bodies together but had no idea what would happen besides Natasha slapping him.

"So ... how do I cool off?" He asked.

"Think of something ... unsexy."

"Unsexy?" Steve replied, puzzled.

"Like... washing the Hulks feet or having to listen to Tony explain physics and technology or Thor recounting some of the animals from Asgard. Something to clear your mind and take the edge off." Natasha explained.

"OK... Stark explaining physics while I'm washing the Hulks feet... urgh." Steve grimaced.

Natasha giggled at his reaction. After 30 seconds Steve seemed much calmer.

"Have you got it under control?"

He nodded.

"Good. Then let's try it out."

Natasha slid back over onto his lap and kissed him deeply, passionately, sensously running her hands through his hair. Steve responded by wrapping his arms around her, stroking down her back. She arched into him her hips and breasts pushing against his body. Steve smiled, delighted. He had never thought in his wildest dreams that he would ever be so close to a beautiful woman or how good it would feel.

It felt amazing, better that anything he had ever expereinced. He brought his hands down to her hips, the weight and pressure bringing her closer to his lap. She was surprised, gasping. He took advantage of it pulling back to go for her neck.

"Ah! Oh!" Natasha whimpered.

Steve started to get more dominate, shifting his hips up to meet hers, his instincts taking over.

"Easy, Cap. Take the edge off." Natasha cautioned.

He sat back on the couch, hands by his side and eyes closed muttering.

"OK. Again. Slower."

Natasha kissed him lightly, stroking his face, running her hands through his hair and finally wrapping her arms around his neck. Steve matched her intensity though it was getting gentler every time.

"Control. Taking the edge off so I can keep going." Steve thought as a silent reminder to himself.

Natasha broke from their kiss and whispered into his ear.

"Very good, Cap."

Natasha slipped off his lap and stood up. She turned to him and continued. "It isn't just about you losing control. It is also about you not rushing your partner. Goodnight, Cap."

"Goodnight? You only just got here."

"True. But you have a lot of homework to do. "

Steve looked down and knew she was right.

"I'll be back tomorrow to test you." And with that she left.

Steve was left alone. This session had been incredibly intestine and had awoken something deep within him, his body reacting in a way he hadn't expected. Instinct had taken over and had shocked an surprised himself and Natasha.

She was right. It would be a long night and the lesson the lesson in control was just what he needed.
