Steve was incapable of speech at the moment. Watching her stretch luxuriously on the bedspread was extraordinary. Hard muscles rippled beneath creamy soft skin as she preened like a cat. She held out her hand and he came to her.

"Lesson number two," she pulled him down beside her. "You can keep your clothes on for as long as you like. Meanwhile, you may touch, taste, feel or explore anything you want. I want to make certain your curiosity is completely satisfied."

He was glad he was sitting down because what little blood remained above his waistline was fighting to evacuate to his more primal regions. "Okay," he said as he swallowed heavily.

Over the next hour, Natasha gave him a thorough lesson in "Our Bodies, Ourselves." By the time they were done, Steve was even more turned on. He felt like his entire body was hard, just waiting to shatter at her touch.

She urged him to lay down next to her and pushed his shirt up. "I'd like to lay against your chest, skin to skin if that's all right."

Steve half sat up and pulled his shirt over his head, "I think I'd like that too."

Natasha lay diagonally across him. She deliberately kept their pelvic regions apart as she settled against him and listened to the powerful thud of his heartbeat. Steve's arms encircled the parts he could reach and held her tightly. Feeling her breasts against his chest and her breathing in sync with his took his flights of fancy to new heights. Softly he kissed the top of her head and stroked her hair.

"I wanted this moment to be with someone special...and it is." Steve whispered to her.

She pushed up to look at him, "Steve, the first time is something you remember forever. If you are happy with it being me then I'm glad. I'm honored that you are allowing me to share this with you."

He pulled her up to kiss her and Natasha shifted in his arms, straddling him again, this time right behind his erection. She eased her hand down and gently freed him from the sweat pants. Steve gave a sharp intake of breath as she encircled his length with her hand.

"You okay?" She asked while gently stroking him.

"Yes," Steve managed to choke out.

"Ready to do this?"

"Shouldn't I be on top?" Steve asked.

"It doesn't matter, it's good a number of ways. This is your fantasy; how do you want to do it?" She grinned and let go of him.

He frowned slightly, taking a moment to admire the view of her sitting on his pelvis. Then he lifted her and lay her down on the bed. He stripped off his sweat pants and settled against her. She opened her legs a little and moved his hand down to her springy curls. With her guidance he could feel her welcoming wet opening. He pushed himself up on his arms and positioned himself over her, already trembling and breathing hard.

"Are you really sure about this, Sweetheart?" The look he gave her was one of unadulterated arousal and a thousand questions flitted through his blue, blue eyes.

He wouldn't be Steve if he didn't give her the out first. His sense of chivalry demanded it even while she was open and ready beneath him and aching for his touch. If she said 'no', he would stop no matter what it cost him personally. Natasha reached down and took him in hand again, pulling his lips to hers with her other arm as she guided him inside, "Mmmm hmmm, so certain."

Steve closed his eyes against the sensation of entering her inch by slow inch while she kissed him deeply. She was hot, wet, welcoming and very pleased by the sounds she was making.

"Oh god, Natasha..." he managed as he gave her his final fraction and filled her. In response, she wrapped her legs around his hips, pulling him in tighter and wriggled against him.

Sensations exploded through him as he felt her clench tighter around him. He hadn't moved yet and she was making him nearly black out.

"Come on, Steve," she urged him, "You won't hurt me."

Slowly he pulled back then pushed in again. As his body moved from hers he felt bereft then filling her again was the most amazing thing he'd ever felt. She pushed her pelvis up to meet each thrust and he very quickly fell into the rhythm she set. Slow. Hard. Steady.

"Look at where we are joined," She panted.

He obeyed her and nearly lost it watching his body moving in and out of hers. "God, Nat..." He was trembling from the over stimulation.

"Steve, you seriously won't hurt me. Do what you need to do. I am here for you, understand?" She grabbed his hair and forced him to look at her.

He kissed her; he had to. His tongue matched the thrusts of his hips, penetrating her in both ways. He knew he couldn't last long. When she dropped her hands to his ass urging him into her, he lost what little control he had. One deep thrust, then another, his hips flexing of their own accord and went over the precipice. He poured into her, whispering her name like an answered prayer. "Natasha..."

She cradled him to her, keeping him inside her and kissing his mouth, gently. "Don't move. I like feeling you on me and inside me."

"Did you…?" he fretted, fairly certain that she hadn't climaxed and it was because he has failed her somehow.

"No, but that's not why we're here. You did everything just perfectly. Give it a few minutes and we can do it again together." She smiled at him and kissed him tenderly. There was no way she would damage his confidence now. Her pleasure could wait till round two.

He had a look of consternation on his face, "Show me how to touch you, please."

"Only if you don't move." Natasha reached down and guided his hand to her. After her show and tell and remembering Bucky's rather crude prior instructions from years ago, Steve quickly found her little bud and the soft folds beneath it where he was lodged. He watched her face as he pleasured her. Felt her orgasm as she clenched around him and kissed her gasps away. He wanted more of that. He wanted to make her climax while he was inside her; hopefully together. Just the thought made him begin to harden again.

"Wow, you've got a great recovery time." Natasha brought his mouth up to hers. By the time he was fully hard she was panting and squirming under him. She got a knee in his ribs and in a surprising show of strength, flipped him on his back.

"Now, I'm going to show you this way," She smiled and leaned down to kiss him as she began a slow, steady ride.

He reached up to touch her breasts, down to grip her hips and never took his eyes off her face. She was glorious. Her hair was back lit by the room light, giving her a fiery halo. Creamy skin which almost glowed, breasts and an ass that fit his hands perfectly. He fit inside her like he was made to be there. This entire experience exceeded every fantasy he'd had. It was perfect. She was perfect. Natasha was everything he could have ever hoped for.

Rocking her pelvis into him, she had to kiss him again and again. She liked it when he grabbed her hips, thrusting up into her. She could see he enjoyed giving as well as receiving. It surprised her though when he sat up, pulled her tight against him and rolled her onto her back. He already learned that steady, even thrusts were more productive for both of them. With the edge off, he was able to maintain control more and assure that her climax came ahead of his. He rode her, enjoying the friction and suction of her canal, pulling him in deeper as he arched back and came at the apex of a thrust.

Afterwards, they lay together, limbs intertwined. When she looked into his eyes she was surprised to find them bright with unshed tears. "Hey, what's wrong?"

"Overthinking things, I suppose." Steve's voice was rougher than usual. It was unsettling.

"Steve, that was wonderful. You were wonderful. Wasn't it good for you?"

"It was the most perfect moment of my life," he said earnestly.

"But..." Natasha said.

"I just thought..."

"You thought it would be with a woman you loved?" She asked it as gently as she could, hoping he wasn't wishing for a chance long past with Peggy.

Steve shook his head, "You don't understand. I am falling for you. I just don't know how to keep you. I know that is ridiculous and old fashioned but after sharing tonight with you, I want this to work with us. Not just as work partners, Nat."

That surprised her. "Steve, you are awfully hard NOT to fall for. I told you I'm here because I do like you. Let's just take things as they come and see where it goes, okay? I'm not going anywhere. There are no other men in my life. This IS special between us. Never for a second think that this was just a pity fuck."

He winced at her usage of the word 'fuck'. "I hope that it could lead to something more."

"Honestly, Steve, you are the sweetest man I've ever met. My heart is pretty jaded but you are welcome to it, whatever that means. I will treasure however long you want me in your life and I will leave when I see that I am no longer of interest or use to you."

"Nat, please don't say that. I really can't imagine you not being in my life. Especially not now." Steve was a complete hopeless romantic, she realized. Natasha felt a brief, unreasonable surge of fury toward Agent Peggy Carter. The least the woman could have done was take him to bed before he crashed into that ice. He had been vulnerable and sweet to begin with. Peggy had known him in his 'before' state yet still left him hanging with a single kiss, knowing how he felt about her.

"Just so you know, despite my reputation, I have never in my life slept with a coworker; especially not a superior officer." Natasha wanted him to know that he really was special in so many ways to her. No matter what else ever came of it, he needed to know that he alone stood out and was important to somebody besides as a hero.

"Thank you for saying so but I tend to draw my own conclusions and not listen to rumors about reputations," Steve said, pulling her back into his embrace. "I would have never entertained anything like this with anyone else. I'm glad we are here together tonight."

Natasha held him closely and did some quick mental mathematics. He'd only been out of the ice for a little over a year. That meant that all his losses: Peggy, Bucky, Erskine; the entire Howling Commandos; his entire life had disappeared for him barely a year ago. He'd been asleep and had not mourned any of them until the day he was revived. Worse, he'd had no one to turn to for comfort or just a friendly ear except for her visits and their missions. It thawed her heart. No wonder he was so unsure and uncertain...so worried about losing her after what they'd just shared. She had completely underestimated his vulnerability when she shouldn't have. At least part of his sadness and disconnect was her fault. As his friend, she should have seen it. "Want to get under the covers?" Natasha asked as she stroked his hair.

Steve looked up at her, "Are you leaving?"

"No, Steve, I'm not leaving." She pulled away and got up to turn off the room light. She turned around to see him turning down the bed for them.

As they snuggled down together, Natasha decided she would protect Steve from anyone who would use him to their own ends. The spy was back on the job with the most important project she'd ever had. He needed a friend and a lover; now he had both.
