She dropped her bag by the door, kicking her shoes off and taking off her coat, throwing it over the back of the couch. She looked over her shoulder at him as he closed the door before turning away again, starting to undress herself. She unbuttoned her blouse, letting it fall to the floor as she unfastened her pants and stepped out of them. She turned to face him, in only her bra and panties now. He'd taken off his coat, putting it with hers, his eyes fixed on her, a shiver running down her spine at his gaze.

He started to move towards her, removing his own clothes until he was just in his boxers. She bit her lower lip subconsciously, her eyes examining his body as he walked toward her, and she felt the heat rush to her cheeks. She wanted to touch him, she wanted him to touch her. But she couldn't just give in to him so quickly.

"God, you look amazing," he murmured as he approached her, his finger brushing over her cheek.

"Just getting ready for bed," she murmured.

"No dinner?"

"I mean," her eyes flickered down his body a moment before looking back up at him, "Maybe."

"I'm starving," he murmured, lowering his lips to her collarbone to press a few soft kisses there, and she resisted the temptation to run her fingers through his hair.

"I can tell," she smirked slightly, tilting her head to the side as his lips moved up her neck.

Just as his lips reached hers, she pulled back slightly so they didn't touch and he raised a silent eyebrow at her. She pressed her lips together and stepped back from him, turning around to head into the bedroom. She knew he was following her, she didn't need to look back to make sure of that.

"Meredith," she heard his voice from behind her and she turned to face where he stood.

"Can I help you, Dr Shepherd?" She asked him.

"You definitely can," he said, a playful glint in his eyes as he moved toward hers again.

His hands moved to her waist, pulling her hips against his as he pressed his lips to hers in what was initially a soft, slow kiss. Her fingers moved into his hair, tangling themselves in his curls as she returned the kiss, brushing her tongue over his lower lip to deepen the kiss. His hands move around to her back, swiftly unclipping her bra and moving the straps off her shoulders.

"Lie down," he murmured, gently nipping her lower lip.

Her tongue traced her lower lip where his teeth had been as she sat down on the bed, leaning back on her arms as she watched him, not wanting him out of her sight. He moved over her, his hand running up her side as he pressed kisses to her shoulder and over her collarbone.

"Lie. Down," he murmured as he nipped her neck, "I'm trying to take care of you, here."

"I don't need taking care of," she whispered, but followed his order to lay down anyway, her arms moving above her head.

"I know, but let me do it anyway," he said as he trailed kisses down to the valley between her breasts, taking one in each hand with a gentle squeeze.

She moaned out softly at the feel of his callous fingers on the sensitive skin of her breast, her breath hitching in her throat as his tongue flickered over her nipple. Her hips moved instinctively up against his as he continued to tease her nipple and she moved one hand to tangle her fingers into his hair again. As he moved to give the same attention to her other breast, one hand brushed down her abdomen, his thumb pressing against her clit to elicit another, louder moan from her.

"God, you're so wet," he groaned slightly as he moved his lips back to hers, his fingers brushing against the wet opening of her pussy with his thumb still moving firmly against her clit.

"I want… inside," she breathed against his lips, her head swimming as she returned his kiss.

"Patience," he murmured, sliding a single finger inside her slowly.

"More… fuck," she gasped as his finger curled inside her, her breaths coming quicker as the heat flushed her skin.

Her gaze followed him as he left a trail of kisses down her body, until his tongue flickered against her clit, his fingers leaving her momentarily to pull her panties down her legs. She whimpered slightly as his tongue teased her, her hips rising up to meet his touch as he slid two fingers back inside her, moving them slowly back and forth.

She slid her fingers into his hair, her walls gripping around her fingers with the build up of her orgasm, his own hand moving up to her breast and massaging her nipple between his fingers. The extra stimulation caused Meredith to cry out in pleasure, his name escaping her lips as he pressed his tongue more firmly against her clit.

"Derek… I'm so," she gasped out between moans.

"Come, baby," he murmured almost inaudibly as he slid his fingers to her clit.

Just as his tongue pushed between her walls, her orgasm hit and she could feel her hips moving with the movement of his tongue as the intense pleasure rushed through her, leaving her brain fuzzy as his hands moved to her hips, gripping gently as his tongue tasted every inch of her.

"Derek," she murmured in her orgasm induced haze, her fingers gently pulling on his hair as he kissed and nipped at her inner thighs.

"Meredith," he breathed, pressing kisses up her body, "You're so gorgeous."

"That was…" she groaned softly as he kissed her again, tasting herself on him as his arm moved under her waist to pull her up against him.

She could feel his hard length pressing against her abdomen and slid her hand between them, gripping him. She could feel his pre-cum dripping onto her fingers and she moved her hand up and down slowly, moaning as his nipped at her lips, soft groans escaping him. One of his hands moved into her hair, gripping it gently and pulling her head back as he moved to kiss and suck at her neck as she continued the manipulation of her hand around him.

"I need you," he groaned softly, "before I finish in your hand. I want to be inside you."

"Wait," she breathed, reaching to her bedside table and pulling a condom out of the drawer.

"Fuck," he gasped as she rolled the condom over his length, squeezing her fingers around him a moment before guiding him to her entrance.

She didn't expect this to last long. He'd been so close, there was no way he could last much longer. He slipped inside her, her walls gripping around him tight as he moved slowly back and forth. Both moaned out as they clung to one another, hips moving in synchronised thrusts, and it wasn't long before their lips were attached again and she could still taste herself on his tongue.

He started moving harder and faster inside her, and she could feel another orgasm building that she really wasn't expecting. He was a thousand times better than she had expected, he had looked good but she didn't know anyone could be this good. She couldn't deny at this moment he was probably the best sex she'd had in her life. Her brain started to go fuzzy as his movements sped up, a layer of sweat between them as they were both reaching their climaxes. As if he wasn't pushing her over the edge enough, his hand gripped into her hair, gently tugging it and titling her head back as he kissed and sucked at her neck.

"Fuck, Derek, oh," she moaned out, her back arching.

"Meredith"

"Yeah?"

"You feel amazing…"

"So close… fuck, Derek."

"Mer… Meredith, fuck."

"Oh, oh," she breathed coming down off her high as he finished, slowly thirsting inside her a few more times, his lips finding hers again in soft, slow kisses.

"That was…"

"Amazing?"

"Better than amazing."

"Hmmm," she groaned softly as he rolled off her and off the bed a moment, going into the bathroom, and she closed her eyes as exhaustion washed over her.

She tensed slightly as she felt his arm move around her middle after a moment, her eyes opening as she turned to look at him. He leaned forward and pressed his lips to hers a moment, and she swore she forgot what she was about to say to him. He gently pulled her closer, bringing the blankets around them as she returned his kiss.

"Sleep," he whispered, pressing a kiss to her forehead.

She didn't know why she did it. Why she buried her face against his shoulder as sleep overtook her, his nose buried against her hair as he held her close. She didn't know why his hold made her feel so safe. Maybe she could just allow herself this for one night. It didn't mean anything. It couldn't mean anything.

He was still here. She was awake, her alarm was going off, it was five in the morning, and he was still here. She was also starving after having not eaten all that much the day before, but that could wait. There was a boy in her bed, and they were never supposed to spend the night. And cuddling certainly was not something she did, ever.

She tensed slightly as his arm pulled her closer, his face buried against her hair. A soft groan escaped his lips and she glanced to him a moment, seeing he was starting to wake up and she shut her eyes, silently praying he would realise he was here when he shouldn't be and leave. But apparently, that was far too much to ask for.

"Your alarm is set for far too early," he grumbled, as she turned away from him, reaching to turn it off.

"Busy day, things to do," she mumbled, "I need to get up, which means you need to get up and leave, because you definitely shouldn't still be here and this was… well it wasn't a mistake, but it was stupid and probably shouldn't have happened, not that I didn't enjoy it, because I did, but it was a bad idea."

"Slow down, it's too early for me to follow what you're saying," he said as she climbed out of the bed.

"Just… I'm going to take a shower and when I get back, you will be gone so… I'll see you later, or whatever," she said, pulling her robe on around herself.

"Do you say that to all the guys you take to bed?" He asked, raising an eyebrow at her.

"Yes… no, no just up, leave," she stammered slightly, going through into the bathroom and closing the door behind her.

She leant against the door, releasing a deep breath as she tried to pull herself together. She just needed to shower, he needed to leave, and she needed to get to work. There was too much happening today for her head to be all over the place. She had a new department head starting, she had to pass on the message from her mother, she had the surgery on Emma… there was just too much. She needed her head to be in the game.

She showered quickly, still feeling sore from last night. Sore in all the right places, mind, but she couldn't think about that right now. She couldn't think about how much she'd give for a repeat of the night before. She wrapped a dry towel around herself before heading back into the bedroom, fully expecting Derek to have left, only to be hit by the strong smell of coffee.

She frowned as she walked to her kitchen, still dressed in only a towel as she tried to seek him out. She stood in the doorway, watching as he poured coffee into two mugs with only his boxers on.

"What are you doing?"

"Making coffee."

"You were supposed to leave. Go home. Shower. Be on time for work."

"And instead I made you coffee."

"I can see that."

"Do you not want coffee?"

"Are you… of course I want coffee," she grumbled as she took the mug and walked back through to the bedroom.

"There we go then."

"But now you need to leave."

"I thought we could drive in together, cut down on fuel costs, and carbon emissions. Good for the planet."

"But then wouldn't you need to come back here again to pick your car up? Because I'm pretty sure I'm going to be staying overnight."

"Yeah, about that… my car was never here."

"Are you kidding me?" she turned on him, anger flashing in her eyes.

"No. I never brought my car in the first place, I left it at home," he shrugged moving toward her.

"You planned this," she pointed her finger, almost jabbing him in the chest with it.

"No… maybe, a little. I think it worked out quite well for both of us."

"You lied to me."

"Wasn't it worth it?"

"You…"

"Because I definitely didn't hear any complaining last night."

"Well last night I didn't know you had lied to get into bed with me."

"And what about now?" he asked, quirking his eyebrow as his hand moved to gently grip her ass, still covered by the towel.

"Derek…"

"Meredith."

"I don't… I don't have time," she breathed as his lips hovered by her neck.

"Yes, you do."

"No… Derek."

"Okay but…"

"Later," she sighed, moving away from him and towards the closet, sipping at the coffee.

"Something to look forward to."

"I guess… you'll need a lift then. Your place or the hospital?"

"I have spare clothes at the hospital, I just need to grab a shower… if that's okay?"

"Yeah, I'll just finished getting ready."

"Not going to join me?"

"First of all, I already had my shower. Secondly, I don't have time!"

"Hey, I was just asking," he smirked at her with a soft laugh before heading through into the bathroom she'd recently emerged from.

She shook her head before starting to get ready herself. He really shouldn't have stayed. She should have made sure he left her apartment the minute they'd finished and instead she'd curled closer to him and slept tangled up in him. It had felt… nice, safe. She had to stop giving into it though. If this was going to be anything, it was just going to be sex, and that was it. By the time he'd come out of the bathroom, dressed with just his hair still damp, she was ready to get going. She just needed to make sure it was clear to him that this was still just sex, just having fun, there'd be no more sleepovers.

"You get this look on your face, you know, when you're thinking about something, like really thinking about something."

"Your point?" she rolled her eyes as she put her coat on and grabbed her bag from where she'd dropped it the night before, checking she had everything.

"Just wondering what you were thinking so hard about," he shrugged grabbing his own coat.

"Nothing for you to worry about right now," she said as she lad the way out of her apartment to where her car was parked up.

"Not right now? So what you're saying is, I should worry about it later on, okay," he nodded, walking close beside her, seemingly intent of using up his pestering quota before it even turned eight in the morning.

"It's far too early to deal with you right now," she commented as she got in the car, gesturing for him to get in the passenger seat, "Come on, you've already made me later than I want to be."

"I like this bossy side of you, have I told you that?" he asked as he put on his seatbelt and she pulled out the car, heading toward the hospital.

She just shook her head in annoyance, turning up the radio as she continued to drive and avoiding glancing over at him even though she kept feeling his eyes on her. She needed to nip this in the bud before he got too comfy around her. He definitely couldn't be like this at the hospital. But for now, she kept her eyes on the road, driving them to work. She just needed to get through another day.
