**This is kinda 16+ and dirty but whatever, don't be offended if its not your thing, you've been warned:)) Thanks for reading..*

Meredith relished the steaming hot water coming from the head of his walk in shower. It was seriously better than the one in the Attendings lounge at the hospital, she appreciated the lack of rubber ducks and bath toys which took residence in her tub at home.

She shaved her legs, started to wash her hair and daydreamed about anything and everything. It was a rarity in itself having no kids bursting through the door interrupting her after a long day at work.

"Mer!" She heard a rattle on one of the two doors leading to the bathroom, one side was connected directly to Nathan's bedroom and the other was the hallway. He was stood behind the hallway side which she had locked. The other side most likely wasn't locked seeing as only he lived there.

She began rinsing the shampoo out of her hair. "What, Nathan?!"

Nathan stood behind the door with a smirk on his face.

"Nothing. Just checking you hadn't fallen down the plug hole"

"Ha-ha! You're just hilarious" She shouted back at him, sarcastically and totally unimpressed.

"You almost done?"

"Nope!" She was, but a few more minutes under the hot water was just what she needed.

"Come on, I need in. It's my shower."

"Yeah well you're a guy. Guys don't take long."

She stood for another couple of minutes and heard nothing more; figuring he'd left her in peace.

The door connected to his bedroom opened slowly. He entered the bathroom, biting his lip knowing for sure he'd be in trouble. Meredith folded her arms across her chest as Nathan stood directly looking at her, naked and wet being cascaded by water.

"Seriously?" She raised her eyebrow. He was smirking profoundly right back at her.

"Uh-huh, seriously." Nathan breathed, his tone lowering. He paced over to the glass shower door and opened it wide enough to see Meredith face to face. She splashed a small handful of water at his face to which he grinned and swiftly shut the door again.

"So are you just being a total pervert or..?"

"Me? Never. I came in for some hot shower sex seeing as it is my place and you're just using all my water before I get in, besides it'll use less water and we'll be all eco friendly."

Meredith laughed loudly, she didn't catch anything else from the sentence he had just said other than the part about sex. "Who said we're having sex?"

Nathan stood directly in front of Meredith, only the glass separating them. He began to strip off his t-shirt ever so slowly so that she would be forced to watch each and every muscle flex in front of her eyes as he pulled it over his head. He threw it down in the corner alongside her things.

His torso was sculpted to perfection and still slightly tanned from the rare rays of sunshine that hit Seattle a couple of weeks ago.

Meredith rolled her eyes at him but was secretly enjoying the show.

His hands trailed down towards the buckle of his belt, making quick work of it. He pulled down the zipper of his jeans and was rapidly free from them. Meredith's eyes scanned down towards his boxers; low and behold he was ready and waiting for her.

His erection was confined within his boxers, for now.

She looked lustfully at his crotch area for a little too long, imagining his cock entering her, stretching her, making her forget about everything but him.

Nathan noticed her staring which automatically boosted his already large ego. When she eventually looked into his eyes his gaze was already on her, a devilish smirk laced his lips.

He couldn't help but stare back at her naked body, thinking entirely about how beautiful she looked under the steady stream of hot water. Her hair was a soaking disarray, falling just above her rounded breasts. She had many scars over her body, a sign that in her life she had lived, suffered hurt and loss, and birthed not one but two babies.

"Do you want me yet?" Nathan questioned. He already knew she did but Meredith didn't give in quite so easily.

"Nope. I'm good."

"Yeah we'll see, what if I do this?" He slid his hand into his boxers and began softly stroking himself, mainly to get a reaction from Meredith.

Her face remained straight. Nathan continued to stroke himself, picking up the pace just a little. It felt good, but not as good as when she did it. The waiting was torturous. A gentle groan escaped from his lips to which Meredith inhaled sharply, she watched him remove his hand from beneath his boxers and pull them down.

His cock immediately sprung free from the restrictive fabric, his length was truly impressive. A burning desire for him suddenly sprung into action, Meredith could feel the heat between her legs. Her hands awkwardly shifted, nails digging into her palms as she bit her lip.

A few seconds passed, the lustful thoughts in Meredith's head were becoming overpowering. She needed to speed the process along; she just needed him in there with her. Fucking her, hard. She was far too turned on by him pleasuring himself she decided to let her right hand wander down to the inner of her thighs.

That got his attention straight away.

His grip on his cock loosened and the pace slowed down almost completely. She lifted her index finger and placed it in her mouth, her tongue coating it in moisture as she sucked. She moved it straight down and into her opening, flinching as she felt something finally in there. Her other hand wandered to her nipple, gently tugging as her head moved back into the water. She manoeuvred her finger in and out of her pussy slowly, becoming more wet down there with each movement.

Picking up the pace she inserted a second finger, closing her eyes as her other hand began messaging her clit. She began breathing erratically due to the added sensation and let a moan escape from her lips. It was a little louder than she expected. She hazily opened her eyes seeing Nathan's chest move as he exhaled sharply, shaking his head.

Seeing her like that, pleasuring herself had the biggest effect on Nathan. He needed her, right now. He strutted over to the shower door, opening it straight away then closing it behind him.

The water cascaded down on him, flattening his dark hair. He pushed Meredith over into the corner in a sudden movement without saying a word; she appreciated the cool tiles against her back, it certainly was hot in there. Nathan pressed right up against her putting his hands either side of her head. He looked deeply into her blue eyes, their naked bodies touching.

He bit his lip, looking down at her as she was still pleasuring herself. "You drive me crazy, Mer." His tone was low and full of desperation.

"Mmm." Meredith breathed, not at all focused on forming any words.

Nathan pulled her into his arms and locked his lips on hers, the kiss was slow and small to start with, his left hand holding the back of her head still. Meredith moaned once again as his soft lips wandered along her neck.

His hand suddenly ran up and down her thigh, grabbing her wrist as he pulled her hand away, her fingers breaking free from inside her.

His finger connected with her clit and began to tantalize her; Meredith could feel his desire for her as his erection pressed against her belly. He ever so carefully slid his finger inside of her opening, juices totally coated his fingers as he added another. Meredith began to pant as he sped up the pace, she gripped her hands around the back of his neck as he continued to kiss her, please her.

She rocked her hips to try and create some friction between them.

"More. I'm so close." She whispered against his lips, totally flustered.

Meredith closed her eyes as he palmed at her clit to heighten her senses even further. He had her exactly where he wanted, just as she started to give in to the pleasure and finally let herself go, he stopped and removed his finger much to her surprise.

Her eyes shot open. What is he doing?!

"No, no, Nathan. Please!" Meredith begged. He was smirking at her, a totally devilish look on his face. "You!" She smacked his chest with both of her hands, creating a loud sound that echoed in the shower.

"Say you want me." Nathan spoke, twirling a lock of her damp hair around his finger, her breathing slowed down.

She gave him the evil eye. "What, and give in to you so easily? I don't think so, Riggs."
