Natasha stood under the much needed, as –hot- as- she- could- stand- it spray of water in her shower of the Avenger's tower. She, Tony and Clint had just come back from a long grueling mission in Wakanda where they helped Black Panther restore order after Man Ape had tried taking over the country again. They'd been there for over two weeks and had aided in repairing the destruction he had caused. Natasha hadn't minded being there but it was always overbearingly hot and her muscles ached with fatigue. So, of course, the very first thing she did when coming back to the tower was to head straight for her bathroom. She hadn't stopped to say hello to anyone. Some things were just too important.

While standing under the shower Natasha became more and more aware of the ever increasing need for something else. She hadn't had any privacy in Wakanda. She had roomed with some of the female warriors of the country and it had been just one giant room with several beds. Definitely no privacy and as a result she had an undeniable itch that needed scratching. She had felt it before they left but hadn't had time to deal with it and now with the hot water pouring over her body she could feel the pulsing of her arousal between her legs.

Turning off the water she didn't even bother toweling off, she headed straight for her bed, enjoying the kiss of cold air on her naked, wet skin. The bed would get wet but, oh well, it'd dry soon enough. Natasha pulled open the drawer of her nightstand and took out her light blue vibrator. She'd found a need for one as she hadn't had sex in about two years. The Avengers kept her too busy to have an actual relationship with someone and, contrary to popular belief; she did not sleep around or do one night stands.

Natasha lay back on her bed and found a comfortable position. With her legs splayed open she turned on the vibrator to her favorite setting which was a constant vibration at high speed and set it on her clit. The pleasure was instantaneous and sent waves rippling through her body that made her nipples peak and harden. While she worked the vibrator with her right hand her left hand skimmed up her body to play with her breast were she squeezed and pulled at her nipple sharply. She slipped the vibrator down to tease at her entrance and used it to drag some of her juices up to her clit. She was so engrossed in her pleasure she didn't even hear that someone had entered her floor and had made their way to her bedroom door that was hanging wide open.

When Tony and Clint had walked into the kitchen after having cleaned up themselves, Steve was glaring into an empty refrigerator. Clint walked up behind him, "Thor and Bruce strike again huh?" Thor was always known for cleaning out the refrigerator and Bruce couldn't really help it. After he turned into the Hulk he was always starving and needing to replace energy. It was just a race to see which one of them made it to the food first.

Steve left out a sigh, "Yes so it's either eat out or order in."

"Order in. I'm exhausted and will only be awake long enough to make my stomach happy. And pizza, please! From that questionable place down on the corner. I'm begging for something unhealthy." Clint said.

"Well I don't know how happy that will make your stomach but pizza's ok with me. How about you Tony?"

Tony was busy downing a good glass of whiskey but gave him the thumps up. Steve just laughed and turned to Clint, "Want to order and I'll go let Natasha know?"

"On it." Clint replied, looking for the number on his phone.

Steve walked down the hall to the elevator. Upon entering he selected Natasha's floor and leaned back against the wall as it went up. The door opened up into the living room that also sectioned off to a kitchenette. Not seeing Natasha there he turned right and headed down the hall towards her bedroom. He turned left into her bedroom and immediately stopped dead. Natasha was lying naked on her bed; head thrown back, legs splayed wide, one hand working her breast and the other moving between her legs.

Steve couldn't move. He wanted to quietly make a run for the elevator but his feet stayed stubbornly rooted to the floor. He heard a tiny pleasure filled gasp escape from her mouth and he felt it like a blow to his stomach, tightening his abdomen and hot blood coursing to his cock. She somehow hadn't noticed him yet and he couldn't help but admire the beautiful sight she made. She must've just come from a shower as her skin had a light sheen made visible by the bedside lamp and her hair fell in messy strands around her head. His gaze traveled down to her chest where he watched her fingers roll her nipple wishing he could replace her fingers with his mouth and the thought caused his mouth to water. His eyes continued further south to see her working something light blue against her clit and when he heard the sound of a light buzzing he realized it was a vibrator. At that realization a low groan escaped from his throat.

Natasha's eyes snapped open and her hands stopped. Steve had the passing thought of OH SHIT before her eyes hooded and became dark and her hands started moving again. A smile graced her lips and she said her voice heavy with longing, "Well, Rogers, are you just going to stand there or are you going come help me out?"

Steve might have been shocked by her words but he was more shocked to find his feet strolling effortlessly towards her side. His feet had been stuck fast to the floor before but now they were light as air. Now at her side he was leaning over her as her hand snaked from her breast to wrap around his head and pull his lips to hers. Sealing their lips together he pushed one hand into her still damp hair and reached the other one down to cup her breast. Natasha flicked the vibrator off and tossed it aside then reaching up to slide her arm around his shoulder and pulled him onto the bed. He stopped long enough to kick off his shoes then he was hovering over top of her with one leg between her thighs. He started kissing down her neck to her collarbone stopping to suckle here and there and when he made it to her breast he sucked a nipple deep into his mouth while his hand pulled and teased the other. His lips on her breast were heaven but she wanted to feel all of him. Natasha groaned pulling his head back to her and sealing their lips back together while pulling his shirt from his pants and undoing the buttons. Steve shrugged off his shirt as Natasha worked on the buckle of his pants, got it and moved on to his button and fly. Getting them undone she pulled up her feet and used them to push his pants down to his knees where he had to get up to take them off.

"Boxers too." Natasha huskily told him.

It dawned on him at that point how far they had gone and how much further they were going to go. Part of him wanted to grab his pants and run but he knew there was no going back now. If there was a possibility of this ruining their friendship then he was sure the damage had already been done. But really there was no way he could turn away from her now. Still he eyed her for any sort of sign that this wasn't what she wanted as he pushed his boxers down and kicked them off his feet. Seeing nothing but want on her face he started back to the bed only to have her sit up and wrap her fingers around his throbbing cock. Natasha looked him straight in the eyes while she stroked his cock up and down then bent her head down to take him in her mouth.

Steve reached a hand to her face to stop her, "You don't have to…" He said.

She pushed forward anyway saying, "But I want to." And took him into her mouth. When he took off his boxers before she knew he was watching her, waiting for her to stop him. He was so painfully handsome, kind and sweet that there was no way she could possibly regret this moment with him. When she took him into her mouth his hand that was still cradling her face reached into her hair. Not pulling or pushing. Just to string his fingers through her hair as another point of contact.

Natasha had her mouth wrapped around his cock but he was very well endowed, probably nine inches long and very thick and she was only able to take the tip of him in her mouth where she tongued and sucked on him. She wrapped her fingers around the base to stroke him where she couldn't reach with her mouth. When she had flattened her tongue against the underside of his cock to curve over the slit of his opening he grunted and gently reached down to pull her away from him. She gave him a questioning look as he pulled her up to seal his mouth over hers. "I want more of you." He said in answer between kisses.

Natasha smiled against his lips and lay back on the bed, pulling him on top of her where he settled between her thighs. His hand went between them, sliding down her tone stomach to the wetness in between her legs. He pushed her outer lips apart to rub his finger against her opening then stroked his finger in and out before adding a second finger. She was very wet and was rocking her hips into his hand. Natasha was more than ready and told him so by whimpering his name pleadingly, "Steve…" and then he was pulling his fingers from her to spread her wetness over his cock before lining himself up at her entrance.

"Natasha, you're sure?" The gentleman in Steve had to ask one last time if this was what she wanted. Natasha looked into Steve's eyes and whispered, "Yes, I want you." and pressed a kiss to his lips. It was scary, she thought, just how much she did want him.

With their lips still pressed together Steve pushed his cock into her wetness. As the head went in he could feel just how tight she was and tried to take it slow when all he wanted was to just surge all the way into her to the hilt. Steve pushed steadily into her until he bottomed out and he waited for her to adjust to him before he started rocking himself into her. He kissed her again then kissed down to her neck and suckled her there.

Natasha breathed a moan into his ear; she had never felt so full before. She felt herself being stretched to the limit. If he had been any bigger it would have been painful. As it was, she was sure it was the best sex she'd ever had. He was so big and she felt so tight that she could feel every slick inch of him pushing in and out of her. It didn't take long before he was picking up the speed of his trusts and she couldn't control when her kegel muscles gripped him every time he went to pull himself from her. It was like her body was demanding he stay seated within her and her mind really couldn't find fault with the idea either.

When Steve pushed into her again his pelvis pushed into her clit and Natasha let loose a cry as she was slammed into cumming hard. Feeling her walls clutch around him and hearing her sharp cry Steve felt his orgasm take hold. It felt like she was trying to pull him into herself. Steve continued to thrust into her, increasing and making the pleasure last, until their orgasms had ebbed. He stopped then, fully seated inside of her and pulling her mouth to his. They kissed hotly while still pulsing with ecstasy. Her walls still clenched and unclenched rhythmically around him and he could feel his cock jerking inside of her in reaction.

When Steve regained some of his mind he went to pull away from her not wanting her to have to take his weight but Natasha locked her legs tighter around his waist. The action made her muscles clench around him again and he let out a groan. He then rolled over onto his back, taking her with him so that she now lay on top of him, his cock still buried inside her. They lay there catching their breaths with her head pillowed on his chest and his one hand draped around her waist while his other hand ran up and down her back.

Steve's mind was slowly coming back to him and his thoughts started to race. What the hell just happened? What's going to happen now? Could they still be team members? Was this a one-time thing? Did he want it to be more? Did she? And then one thought made him jolt underneath her. She looked up at him curiously.

Reading the concern and panic on his face to be because of what they just did a soft smile spread over her face before she said, "It's okay, Steve. We can figure this out."

"That's not it, Natasha. We didn't use any protection."

Natasha let out a breathy laugh before she laid her head back on his chest and his arms instinctively wrapped around her again. He frowned at her laugh, "You could get pregnant." He pointed out.

"Nope. Because of the serum the Red Room gave me, my white blood cells react faster to any foreign substances in my body and destroys them. As a result, I cannot get pregnant." She tells him in a matter of fact tone.

Steve's frown deepens, "That doesn't bother you?"

Natasha lets out a breath that drifted across his chest, "It doesn't matter if it does. There's nothing that can be done about it. I've chosen to accept it and move on."

They laid there in silence then, simply enjoying being in the other's arms, until they heard Jarvis' voice fill the room.

"Sir Tony would like me to inform you that the pizza has arrived and if you do not hurry Sir Clint will eat it all. Shall I tell them you are preoccupied?"

Natasha and Steve both laughed. Jarvis sure did have one hell of a personality.

"Food?" Natasha could feel Steve's voice rumble through his chest.

"Yes, definitely food!" She said sitting up and pulling herself away from him. His cock, which had still been inside her, pulled out of her as she moved and they gasped. Both wished they could stay where they were. But Natasha could feel her stomach grumble at the thought of food. So she instead pulled Steve in for one last lingering kiss that he eagerly returned before she crossed over to her dresser and pulled out a sports bra, sweatpants and baggy t-shirt. They both dressed and Steve tried to make himself as presentable as possible but he was still looking pretty rumpled.

Natasha giggled and tried to smooth his hair back a bit. He caught her hands in both of his and looked her in the eyes with an affectionate smile. She said, "We will talk about this, Steve. I do like you. I wouldn't have asked you for help if I didn't. And by the way, you help out pretty good." She grinned up at him and turned to walk out of the bedroom. Steve let out a husky chuckle before following after her.
