This chapter was inspired by the sexy, but much too short, little scene where Meredith comes to Derek's office after finding out that April had that little crush on him. Where she calls him Chief Shepherd, sitting on his desk...this expands on that theme...hope you enjoy...it's definitely more adult rated than what we got on the show LOL.

Chapter Six - Office Escapade

"So, how's things with that new girlfriend?" Addison asked Derek as he poured a cup of coffee. She leaned a little closer to him, pulling the collar of his shirt aside with a little whistle. "Must be good, judging from the size of that hickey…"

"It's just fine," he sighed. "I think."

"Do tell." Addison raised her eyebrows over her coffee cup. "You mean you're still with the same woman after all this time? That's some kind of record for you, isn't it?'

"Don't start with me, Addison."

"Oohh…touchy today?" She couldn't help but tease him just a little bit, as they walked along the corridor.

"Don't you have work to do?" he asked, stopping at his office.

"Of course, but this is much more interesting."

"Look, she's driving me crazy, if you must know," Derek admitted. "Just when I think I have her figured out, she does something that totally surprises me. Or she's pissed at me for something I didn't even know I did." He thought of the crazy places they'd been intimate, the way she was able to make him do things he didn't normally do. Having steamy sex in the backseat of his car was just one of those things, and his body felt a wash of heat at that recollection.

"Maybe that's a good thing – you need to have your ego shook up a little bit from time to time…"

"My ego?"

"You're the one that's usually in charge, Derek. You're just having a difficult time accepting the fact she's got your heart in her talented surgeon's hands…"

"Hell no, Addison…I'm not in love with Meredith…it's just physical…"

"Seriously?"

"Yes, seriously. And I'm still in charge…"

Addison watched him stalk away into his office, and she grinned to herself. He was in denial… no doubt about it.

"So…this is your office…" Meredith commented, walking along the carpeted hallway on a Sunday afternoon. Rain was beating down outside, and their afternoon escapade to the waterfront had been postponed. Derek decided to swing by his office to pick up some files, so he brought her up with him before heading home. They would need to find some indoor activities to keep themselves occupied, and he was looking forward to having her in his bed, shutting out the rest of the world for awhile.

"So it's just you and your partner?"she asked him.

"Addison, yes…and we share a secretary…it's nothing exciting," he grinned, shaking water from his jacket.

"Still…nice to see where the law is practiced…" she murmured.

"But you hate lawyers," he reminded her. "As you've pointed out once or twice."

Meredith shrugged. "My cousin went through a bad divorce…left me thinking the worst of your profession."

"Really? Well, you know we aren't all like that…"

"You know that old joke…what do you call a thousand lawyers at the bottom of the ocean?"

"A good start…" Derek grimaced, as he ushered her into his office.

"Oh you've heard that one…"

'Several times…" he told her dryly. "Now, just hang on a minute, and we can go." He sat down at this desk, and opened his file drawer.

Meredith shut the door behind her, and unzipped her rain jacket, dropping it to the floor. "Oh…I don't know…maybe we should take advantage of this…" she said softly. "Mr. Shepherd…are you sure you're in a hurry?" Her smile teased him, and he looked at her in surprise.

"Well…maybe not…" he grinned, leaning back in the high back chair, watching her advance slowly.

"Oh good…maybe you want me to take some dictation…can I be your secretary today….?" she murmured, moving between him and the desk. She lifted herself up onto it, spreading her legs apart. "Mr. Shepherd…I'm ready for whatever you want…just tell me how I can serve you…pick up your dry cleaning? Wash your car?" She tossed her hair, giving him a saucy smile.

"Ah, well…if you put it that way…maybe you can help me with something…" His hand strayed to his belt, pulling it open slowly. "You're doing your best to arouse me, aren't you?"

"Why, Mr. Shepherd…I have no idea what you mean," she gasped, putting her hand to her chest, and toying with the button that held her shirt together across her breasts. Her tongue flicked along her bottom lip, making his blood pressure jump.

"Don't play so innocent, Miss Grey," Derek told her, taking her hand and pulling her closer, falling into whatever little game she was playing.

Meredith paused, watching the play of desire across his face, seeing his eyes darken as they swept over her. She bent over, and he leaned in close to her, his breath fanning her cheek, his hand on hers. "What…am I turning you on, Mr. Shepherd? Do you want to take advantage of me?"

Derek's other hand slid lower, across her ass, and beneath her skirt. Meredith froze, as he explored the curves roughly. "Always, Miss Grey…"

"So you've got me in your office all alone, Mr. Shepherd…maybe you want to show me your legal briefs?" she asked breathlessly, as his fingers danced along the bottom edge of the panties beneath her short skirt.

Derek laughed softly. "Good point, Miss Grey…I have this terrible desire to take you in every way imaginable, until you scream for more. Do you think you can help me with that?"

"Oh…" Meredith gasped again, as his fingers suddenly delved between her ass cheeks, sending a little shock along her spine. "What are you doing, Mr. Shepherd?"

"Don't pretend you don't like that," Derek murmured, as she shook beside him. He ran his tongue along the delicate edge of her ear, twisting his fingers against her. "You're teasing me, my dear…what do you expect me to do about that?"

Abruptly, he let her go, and she moaned, the ache in her clit making her dizzy. "I d-don't know, Mr. Shepherd…spank me if I'm not doing what you want?"

"Spanking…now there's an area we haven't explored," Derek noted, pulling her down into his lap. His hand cupped her breast, yanking the shirt apart, so that it gaped open further. He bent his head and snaked his tongue over the cleavage created by the bra, nipping her soft skin as well. Meredith squirmed against his cock, and he bit back a groan. "But if you like that…maybe I can accommodate you…"

"Y-yes…whatever you want," Meredith whimpered, caught between wanting the discipline, and wanting his cock. It bumped against her, and she slid her hand over him.

"Don't distract me," Derek warned her, removing her hand. "You can have that later, as your reward."

"Yes, yes…I'm all yours," Meredith replied, closing her eyes.

Derek shifted so that she had to get off his lap, and he stood beside her, reining in his own desire for the moment. Before she knew what he was going to do, he crashed his lips over hers, and his tongue was in her mouth. Gasping, she responded, kissing him back just as forcefully, meeting his tongue, reaching up on her toes to press against him. As he drew back, she grazed his lips with her teeth, and he jerked. "Naughty naughty….you've just added to your discipline," Derek rubbed his bottom lip slowly.

"So…make me behave…" Meredith taunted him, eager to get into it. Her hands strayed along the buttons on her shirt, undoing them one by one, revealing her upper body to him.

"Ohhh….you will behave," Derek vowed, grabbing her arm and turning her away from him, towards the wall. "Put your hands up, and don't move," he breathed in her ear, his hand running along her body, between her legs, spreading her wider apart. His fingers brushed her hip, suggestive and familiar, giving her a jolt of heat.

"Derek…" Meredith panted, already drenched, so wet for him it wasn't hard to quiver in mock-fear.

"Don't move."

"No, I won't…"

Derek caressed the curve of her ass in the silky pink panties, as she shook in anticipation. "Hold still…" he murmured in her ear, easing the silk down her legs. His hand returned to her ass, giving her a quick little tap that made her gasp in surprise.

"Oh…you really want to do this…" she murmured, peeking over her shoulder at him. Her eyes were wide, and her teeth caught her bottom lip.

"You started this little game…" he reminded her, giving her another little swat to emphasize his point.

"I know…"

"So how do you want to finish it?"

"Your desk…" she sighed, nearly lost in the way he made her feel, her legs shaking as he caressed her. "I have this fantasy of you and me on your desk…"

"Well, then let's make that a reality…" he grinned, tugging her towards the large oak desk. He lifted her upwards, and she swept away the papers there unceremoniously, leaning back to show him just how much she wanted him.

"Like this…" she sighed, "it's crazy, but…"

"So I like crazy…" he breathed, spreading her legs wider, mesmerized by the dampness of her pussy.

Meredith leaned back on her elbows. . "I'm throbbing, and I think I need your talented tongue to make it better…"

"Yes, I see…that can be a terrible torture, I'm sure," Derek agreed, placing his palm against her, feeling the wetness seeping out of her. "Let me see what I can do to relieve that…"

"Please…you have no idea how much I think about how you make me feel…" she sighed. It was getting to be an addiction, she thought hazily, but she wasn't about to tell him that.

"I'm getting the idea," Derek assured her, spreading her apart, and touching her with the tip of his tongue. Gliding across the damp folds, searching for her clit, as Meredith sighed in relief. He drove deeper, stroking, licking and sucking, until she screamed and writhed under his hands.

"God..yes…YES! Just like that, oh god, I need that…" Meredith cried out, as the orgasm surged through her body. "God oh god…." Her mind went blank, and she lost herself in the pleasure he was giving her again and again, until she thought she couldn't take anymore. Only when she screamed and finally collapsed backwards, did he let her go.

"Is that better now?" Derek asked, pulling her back up against him.

"Oh god yes…but I need you inside of me…now…" she demanded, reaching for him.

"Hell yes," Derek growled, pushing her backwards, scattering the rest of the papers away without any thought of what kind of mess it was making. His cock throbbed hotly between her legs, and the feel of wetness against him nearly made him explode right then and there. "Mer…" he groaned, as the touch of her fingers against his engorged cock made him shudder.

"Just take me now…" she urged, opening herself to him, guiding him inside, where she was wet and waiting.

"You feel so damn good," he groaned, sliding into her slick heat. Meredith was lost then, in a molten swirl of lust so overwhelming she thought she could combust from it. It was all that mattered – his hands at her hips, his cock thrusting in and out, taking them both to the edge of ecstasy and beyond. Her body ached, as Derek slowly pushed into her, giving her the fullness of him in one slow thrust. She was so wet and hot, and he was buried so deeply, it seemed impossible to be any more connected. He lifted his head, and he could see her eyes on his cock, sliding in and out of her tightness, so hot and demanding, her breasts moving with each thrust as she took him in with each stroke.

"Okay baby...this is it...take it now..." And he pushed against her again, shooting deep as his balls tightened up, releasing with an intensity that took his brain somewhere else. Somewhere hot and blinding, as she fell backwards, panting and sweaty, the aftershocks firing between them.

"Oh…Mr. Shepherd…" she giggled, once they regained some semblance of sanity, "you are so amazing…"

"Pretty damn good yourself, Miss Grey…" he chuckled. "You can take advantage of me like this anytime you want…"

BTW...Addison in this story is actually nice...something I don't normally do, but part of the fun is having the characters show up in unexpected roles, isn't it?
