As she walked into the bedroom, Steve closed the door behind them before walking over to the other side. YN placed her wine glass on the bedside cabinet and removed the clips from her hair, her locks cascading done her back. She could feel her heart pulsating, the adrenaline rushing through her veins. She placed her clips beside her empty glass before turning to Steve who was stood beside the bed, hands in pockets and nerves scattered all over his face. She slipped out of her heels before walking over to him, a shaky breath slipping through his own lips the closer she got.

"Are you sure you want to do this Steve?" YN questioned looking into his crystal blues. They flickered between her own and occasionally flew to her lips before he swallowed the obvious lump in his throat.

"I'm sure. Are you?" He questioned back. YN stood still her gaze not faltering before she tiptoed, placed a small hand on the back of his neck and pulled his lips to hers. It was gentle at first before his hands found her waist, rubbing gentle circles into her skin.

Steve had kissed people before but it was just a basic make out session and he knew it wasn't going to lead to anything other than that, but this.. this was a whole different ball game. He wanted to impress.

YN pulled her hand down his chest, her other hand joining in as she pushed his suit jacket off of his shoulders, revealing the tight fitted dress shirt beneath. She pulled away for a moment to admire him. She could see the faint outline of his abs and pecks through the shirt which caused a pulse through her core.

Throwing his jacket to the side she pulled his shirt from the waistband before unbuttoning it one by one not taking her eyes off of Steve's. His breathing seemed fairly steady considering, but then again he was Captain America. He didn't really have anything to be insecure about. After all his buttons were undone, YN placed her palms on his abdomen before dragging them over his skin, admiring the work of art sculpted into him.

Steve gently pulled his shirt off tossing it to the floor beside his jacket. He cupped YNs cheeks before pulling her into another kiss, this one more heated than the last. She closed her eyes and enjoyed the feel and taste of his lips, a sweet but minty flavour. He nearly had her come undone right then and there.

YN pulled on his belt, pulling him towards the bed until the back of her knees hit the mattress and she fell onto it breaking the kiss. She was sat on the mattress, eye level with Steve's crotch which had a visible erection. Looking up at him YN placed her hands on his buckle undoing it slowly before pulling it from the loopholes.

"What-" Steve gasped. YN bit her lip with a smirk and unbuttoned his pants, pulling down the zipper and eventually pushing the fabric down his extremely thick but firm thighs.

Steve knew what she was planning to do and that's when the nerves really settled into his skin. He'd never been bare to a woman before, yes he's taken his shirt off in front of people that's kind of a given but for someone to see his most intimate and private part of him was scary. But it also made him feel a tingling in the pit of his stomach.

"Shh.." YN cooed before standing up and switching places with Steve, pushing him to sit down whilst she stood over him. YN planted another kiss on his lips before pulling away and wiping her thumb across his bottom lip. This was the first time she was also nervous to have sex. Captain America trusted her to be his first and she didn't really know how to take that.

YN got on her knees and pressed a little kiss just above the waist line of Steve's boxes before hooking her fingers into the waistband and sliding them off slowly, Steve lifting up ever so slightly to allow them to slide down his legs. His erection sprung free and YN couldn't help but let out a little gasp at the sight of him.

Long, pink and desperate for attention.

"Do you trust me Steve?" YN asked as she saw Steve's breathing pick up the moment she saw him. A vigorous nod erupting from Steve head as he stared down at her. "I need to hear you Steve."

"I trust you."

YN smiled before wrapping her fingers around the base of his cock. A small hiss came from Steve's lips as she tightened her grip ever so slightly. Leaning up to press a small kiss to the tip she never broke eye contact with Steve, big blue eyes now clouded by lust. She wrapped her lips around the tip sucking gently, her tongue swirling around. Steve let out a low groan before placing his hand on the back of her head, fingers tangled between her hair.

Pushing her head down further to take more of him a small gag escaped her throat sending a insatiable feeling down Steve's member. YN pushed as far as could before pulling her head up and repeating the action, the sounds of wet slurping filling the room alongside the sweet moans of Steve, as she devoured him. Her lips, her throat and her hand all working in tandem to please him as best she could.

YN could sense that he was about explode when his hand tightened on her hair and he was using his own initiative to push her further down. Pulling her head away from him she took a deep breath and looked at Steve who through himself back against the bed, sweat trickling down his abs and forehead, deep breaths spilling from his throat.

YN slipped out of her dress, pulling her bra and pants off before straddling Steve's hips. His eyes flicked to her face before they roamed her naked body. YN grabbed him large hands and placed them on her breasts using them to massage her breasts before he began to do it on his own. He uses his thumb and forefingers to roll, flick and squeeze the little nub on her breasts causing YN to throw her head back gently in pleasure. She tenderly ground her core onto his member, moving up and down against his member her slick covering him.

Steve looked in awe of YN like he'd never seen something so beautiful in his life, the way her body reacted to his touch, the fact he is causing the expression of pure ecstasy across her beautiful feature. She brought her gaze to his own and for moment he thought he saw an emotion of adoration splash through her eyes but it was gone just as quick as arrived.

"Are you ready Steve?" She asked and Steve smiled lightly.

"I'm ready YN."

With that YN grabbed the base of his cock and placed it at her entrance rubbing his tip through her folds. It had only really dawned on her how big Steve actually was and a pinch of panic flooded her system but she pushed it to the back of her mind as she gently pushed him into her soaking and warm hole.

Steve closed his eyes as his month formed a perfect 'o' in pleasure. The way her walls gripped him and how smooth and silky it felt to be inside her, the way she gasped and moaned at him stretching her. As she sank further and further Steve felt more and more confident.

Once he was fully sheathed inside her she stayed still for a moment or two and gathered herself together before she used his chest to push herself up and down his length.

"Shit.." Steve whispered his hands going to her hips to aid her in moving up and down his length. "Shit this feels too good."

"You're so big Steve, so big." She moaned picking up her speed, grinding her pelvis into his causing a friction against her clit. With that and Steve's pulsating cock pushing against her g-spot she was close to an orgasm. Never had any man brought her an orgasm from just penetration but she could feel the coil tightening in her stomach.

Steve on the other hand was a moaning mess.

His voice was muttering all sorts of words and groans. His eyes scanned YNs features and he couldn't stop the feeling he felt as her head rolled back, eyes closed and mouth open with moans tumbling out. Something snapped in Steve and he wrapped an arm around the back of YN before flipping them over so he was on top.

He began thrusting faster and faster into YNs core, the squelching sound echoing around the room with their moans and gasps. Taking both of her hands and pushing them above her head, his hands not leaving her as he leans in gently, lips inches away for hers as his hot breath fans her face. YNs eyes met Steve's as he pressed his nose to hers, his thrusts becoming more rapid.

He was close.

"YN.. I'm-"

"Me-me too Steve." She panted, she pulled her left hand from Steve's and placed it on his head pulling him for a long kiss as the coil tightened after every thrust.

Steve felt the way she squeezed him, her walls clenching harder than before. He used his brain and realised she was going to cum. Steve pulled his lips away as YN let out a cry of pleasure as her organs ripped through her, her legs wrapping around his waist pulling him even more, if that was even possible.

Steve didn't stop his unrelenting pace before his own orgasm rippled through his body tearing a groan of pleasure through his throat. The pleasure was so intense that Steve forgot to pull out or even think about using protection. Riding himself through his orgasm and YN hers he dropped his head onto YNs shoulder, panting and trying to catch his breath.

"That.. that was amazing YN." Steve said as he pulled himself up and out of the woman lay before him. YN lay their speechless, her body drizzled with sweat and shallow breaths pushing past her lips.

"Yeah. It was."
