15 : TRILOGY TIME*

Natasha Romanoff underneath him was the only thing he ever wanted and now she was lying down in his bed, naked, panting, and moaning. Her moans were the most beautiful sound he had ever heard. Finally, he had gotten the chance to taste the forbidden fruit and he would go to hell and back again to taste it. Well, he never thought she would give herself to him this easily.

His lips and hands trailed up and down her body, making her shudder underneath him. His teeth marked her as he left purple marks on her soft skin, he needed to claim her as his own. Natasha's hands grabbed his hair, she didn't push him away instead she encouraged him to continue his exploration with his lips and hands. He went down until his lips and tongue settled between her legs before lightly biting on her inner thighs.

"God, you're soaking wet, Nat." He groaned as his two fingers slipped easily into her hot and tight core. Nat let out a moan of pure pleasure. Her hips started to move. He could feel that she just wanted to fuck herself against his fingers so he used one free hand to grip her hips and forced her to stay still. His tongue worked on her clit as Natasha couldn't hold her moan and his name left her mouth.

He had all night to make her his.

"Steve…please, I need you to—" She gasped, trying hard to catch a breath. He looked up at her, she was the most exquisite thing he ever seen. Her cheeks were tinted pink, her breaths came in short gasps, her lips parting, and letting out a few loose moan she was trying to hold back. He dragged his tongue up her slit, suckling at the sweet, swollen clit. He wouldn't not give it to her unless she begged him to.

Begged him to fuck her liked most of the girls do.

"What do you need from me, Tasha?" He murmured. He would deny her unless she asked him for it.

"Please—I want you inside me!" She cried out. He lifted his head up and positioned himself between her thighs. Steve bend down to kiss her full lips again, sharing the taste of her own arousal. He pulled away, eyes locking on her.

"Ready for me, baby." He whispered before slowly pushing himself inside her. Steve cried out at the sensation of the first thrust. "God, Nat." He groaned, eyes closing, tipping his head back "God. You're so tight."

She felt so good and incredibly tight. She felt like heaven to be more precise. He removed himself slowly before slamming back in. He was trying to control himself but every moan that escaped her mouth only make him want to go harder. He was so drunk on the feel of her heat and how he felt with every thrust he made. His head tipping back with pure ecstasy.

Natasha pulled him down for a kiss. Her body arching and her hands grabbed his muscled back as her fingernails dug in to his flesh. The sound she made was music to his ears, only making him more and more aroused, and hammered his way into her

He could feel her orgasm was building up. He was close too but as a perfect gentleman he was, he always pleasured the ladies first. Natasha screamed when Steve thrust one last time before she was tipping over the edge. Her walls tightened around him like it was trying to milk every drop of his. She convulsed beneath him and the pleasure was so raw that Steve couldn't hold back and followed her over the edge.

"Fuck!" He shouted as he was coming hard inside her.

"Fuck!" Steve heard himself shout. He was abruptly woken up because of a dream. A dream of burying himself between Natasha's thighs, Damn Stark for his pool party plan that allowed him to see Natasha in the most revealing state he could possibly see her.

It's not that he never dreamt about her before. He dreamed about her a lot but not like this. Not like he was having sex on fire with her. Burying himself deep and releasing himself inside her heavenly body. He knew she had been in his mind a lot lately but he never ever thought that she would reflex into his mind with something like that.

You're a real pervert, Rogers. He muttered in his head but he knew that it was hard for a man who still alive not to fantasize about her. The creamy soft body, the most gorgeous curves, D cup size breasts, some lingerie model would die to have her body and Natasha Romanoff didn't even have to try.

Fuck! Stop thinking about her right now! The thought about her only made the throbbing pain in his sweat pants worse. He needed to do something about it. Steve rolled himself on his stomach and the friction he felt nearly made him lose it. He got up from his bed. Apparently whatever he was trying to do was too slow and he was thinking about Natasha again. It was the hottest, sexiest dream his pervert brain could ever produce even though he knew he shouldn't do it.

This is really bad, Steve thought and tried to calm himself down. You have never dreamt about any girl like that before Steven! And that should be the last time. She is your friend! Show some respect, you bastard!

Steve needed to clear his head and get rid of the pain between his legs by doing something so his blood would flow somewhere else. The Captain grabbed his towel and headed to the shower.

You shouldn't do that. He thought to himself. She is your friend, not some random chick you just fuck and discard, Rogers. You cannot allow Natasha to be in your dream ever again!

Steve quickly stood under the cold stream of the shower alone in the common shower room. It did help somehow, at least he could walk back to his room without offending someone who would woke up 6 am in Saturday morning. Steve stepped out of the shower and dressed up. He still needed to clear his head. He couldn't let himself think of Natasha that way again.

The only place that was quiet enough was the rooftop.

As he stepped out of the staircase, he saw someone had already occupied his rooftop. The girl he was trying to get out of his mind, standing there. She didn't even notice he was there.

"What are you doing up here, Natasha?" Steve asked.

She startled and turned to him, "What are you doing here, Rogers?"

"I asked you first." He retorted but he knew she would not answer to him so he told her. "Fine, I just came up here to clear my head."

"Me too." He was now standing next to her.

"Don't just copy my answer, Romanoff."

"I really am thinking." She said. "What are you thinking about?" YOU! He shouted in his head,

"Uh—my dream."

"Nightmare?" Steve shook his head.

"Not exactly but something that can make you feel like you are in hell" He lied. "What about you?"

"I just broke up with that guy."

"What?! The guy that was so delightful you ditched me for him?" He asked. "Did he hurt you or something? I will take care of it."

"No, I'm the one who broke things off." She said. "He just wanted me for sex." Steve frowned as he could see the slightest hints of sadness in her eyes but before he could ask for more information, Natasha did something that took him by surprise. She pulled a cigarette out of a pack and lighted it up. Steve quickly snatched it out of her hand, threw it on the floor and squashed it with his foot.

"What the hell you think you are doing?" He asked loudly. "You smoke?"

"It's not a big deal, Rogers." She rolled her eyes and pulled out another one. This time Steve grabbed the whole pack and threw it down from the rooftop. 'What the hell, Steve?!" She bellowed.

"It's a big deal because it kill you!"

"I'm Russian. We all smoke!"

"That does not justify smoking!" he replied. "Don't do it again."

"It's none of your business, Rogers!" Steve changed his approach and put his hand gently on her shoulders.

"Please listen to me, Nat. Stop smoking. It will kill you. It's never too late to stop."

"I've been trying for a long time, Steve, but it didn't work. I started smoking in high school with Alexei." He frowned again when he heard that name.

"I thought you were saying you wanted to move on. Why don't you start with this simple thing, Natasha? Quitting smoking is the best way to start your new life." Natasha had to admit. He could be very persuasive. No wonder everyone always makes him a leader. She sighed and said,

"I'm trying to quit. It's on top of my list since I came to America."

"What?! 'My List'? You have a list?" He asked. "You don't need a list of thing you want to do, Romanoff. You just do whatever you want when you feel like you want to."

"You say that like you've never have a list of thing you want to do."

"Nah, my dad pretty much planned my life since I was born so….Nope! I don't want any to-do list." He replied. "Do you have an actual list or it just a mental note?"

"I have an actual list but I'm not gonna show it to you."

"Okay, I won't push you any further this time." He said. "But Nat, please try to stop." The level of seriousness in his eyes and his voice surprised Natasha. He held her hands gently. He was almost…Begging?

"I said I will try."

"I will be there to pull you back from the cliff then." He said with his full smile.

"Thank you, Steve."

Steve picked Natasha up at her room as usual. He also brought Natasha her favorite sandwiches she once told him about the little breakfast bistro a couple south from the university. When she saw it, she practically squealed with joy and hugged him.

"You're the best." She said. Steve felt his heart fluttering at her appreciation and her joy. She smiled again. She was smiling, not crying. At least, he never made his little red cry.

"Yeah, I know." He shrugged his shoulders casually. His eyes twinkled when he added, "I know how to please the ladies, especially the beautiful ones."

"Oh! You're such a jerk." She mocked a groan. "But glad to know that I'm beautiful to you."

"You are beautiful, princess." Natasha's cheeks tinted pink as she heard his words. It's not supposed to feel like this. Her eyes met his blue ones for a second before averting to look at something else. His gaze alone can made any girl's leg wobble. But the message tone from his phone broke the intense moment between them. Steve pulled out his phone and his face frowned when he read the message out loud.

"Stark sent me 'Assemble at my room for a Trilogy Time this evening.'"

"Sound like fun..."

"Why you sound like you are not sure that it will be fun?"

"Uh—nothing." Steve let her lie slide this time.

"We can meet back at his room so you don't have to wait for my football practice."

"Okay."

Steve had just arrived at Tony's room. He knew he was late but he had a good reason for it and he was about to brag it to his friends. Steve burst the door open and announced excitingly,

"There's a girl I just met today!"

"Quiet Steve." Natasha shooed.

"You're late for our trilogy time!" Tony yelled. But Steve didn't listen to them and continued with his story.

"You're not gonna believe it. After I finished my practice and Thor ditched me to grab some pizza with Jane, she was waiting for me at my car and guess what."

"You slept with her." Pepper said quietly because she already knew the answer.

"I had sex with her in the car!"

"Ewwwww!" Natasha threw popcorn at him. "I will not get in your car ever again, Rogers."

"Oh you don't know what your missing out on, Romanoff." Steve sat down next to Natasha on the couch and grabbed a handful of popcorn but in his mind he thought about something else and forgot to pay any attention to the movie.

The moment when Natasha said 'Eww'. Her face and her voice were completely disgusted by his behavior. It sounded so disgusting that he felt like he shouldn't do what he was doing if it make her feels such disgust about him. What's the fuck are you thinking, Rogers? The little devil Steve yelled inside his head. She is just a girl and you should totally ignore her comment about your sex life!

The little angel Steve appeared in his head too. You should stop with your random sex, Steven. If you want her to think of you more than just a womanizer idiot who never treats a girl the way you should.

You two just shut the fuck up. You're making me more confused than I already was! Steve said in his head to get rid off all the thoughts.

But then he felt her head lean against his shoulder and all his thought was shifted to focus only at her. Half ways through the second movie, Natasha fell asleep on Steve's chest who wrapped his arms around her gently as drifted off when the second one finished. When the movies were all finished, Pepper flicked the light on. Tony saw the sight he never thought he would see.

Steve and Natasha snuggled on the couch.

"If I didn't know them better, I might think that they were dating." The rich boy said and snapped a picture.

"Yeah, dude. I agree with you on this" Clint chimed in.

"They are just friends!" Bruce interrupted

Pepper woke them up gently. Natasha nuzzled her head with Steve's chest before slowly opening her eyes. He didn't move when he realized how close he and Natasha were. His little red had curled herself into him.

"We have to do that again." Natasha said. "I didn't watch it. I can't cross this one out of my list."

"What list?"

"List of thing she want to do, but has never done" Steve replied which earned him a curious glare from everyone.

"You never watched Star Wars? YOU NEVER WATCHED STAR WARS?! What an outer space country are you from, Romanoff?" Tony laughed. "Did you come from a country with no electricity or something?"

"Laugh all you want but my dad never let me watch an American ass film."

"Since you are on your way to becoming a citizen of this American ass country, you gotta watch Star Wars. I will send the group an assemble text next time when we want to do a trilogy again."

They ended up arguing about this for a solid half an hour. Darcy and Maria were yelling at Tony and Clint. Phil tried to stop them while Bruce and Pepper just wanted to stay out of this until Steve finally yawned loudly and excused himself back to his room with Natasha following behind. Steve also ended up walking her back to her room.

"Night night, princess." He said gently.

"Night, Steve."
