A/N: So this is an embarrassing display of my porn writing abilities. It's 6 am so I'm not going to read over this. There may be mistakes. Maybe this isn't original. I don't know. I haven't read any like this...anyway. I may continue it but I need input.

Something Worth Knowing

Mark : So this could be just a drink or this could be more than just a drink.

Meredith: I cannot start something with you.

Mark: You could. (pauses) Start over, Meredith. Start fresh.

Meredith stared at Mark, unable to believe that he was actually proposing that they start something. He stared straight back, his face serious. She sat back in her chair, her mind actually going there. She could scarcely believe that she was considering it, but it wasn't exactly a bad thought.

Mark slowly grinned when he saw the contemplative look on her face. "I'm good in bed," he promised her. "And I'm extremely good looking. I'm not complicated, and my emotional baggage is just run of the mill childhood trauma."

Meredith rolled her eyes. "Are you propositioning me or giving me a sales pitch?"

"At this point, what's the difference?" Mark leaned forward, giving her an intense look, completely serious. "We've both been burned, you know my past and I know yours. And I happen to be really great at anticipating women's needs."

"Bringing up the obvious fact that you're a man whore," Meredith said. "That's a good way to get into my pants."

"I'm not trying to scare you away. You already know who I am and how I am. My past doesn't get much worse than what I did to Derek. I'm not emphasizing the fact that I sleep with a lot of women. I'm just pointing out that I know what you need."

"Yeah?" Meredith challenged. "What?"

"Uncomplicated, no strings attached sex." Mark shrugged and gave her a charming smile.

"That is the most absurd, unbelievably arrogant thing I've ever heard a person utter," Meredith informed him.

"But so true. Think about what I'm offering here. Sex without strings. No mushy feelings, no thoughts on whether or not I'll call you later…"

"Would we be exclusive?" Meredith asked after a few moments of thoughtful silence. She stopped him before he could say anything. "Don't lie to me. I know you and Dr. Montgomery have a thing."

"The thing, as you so eloquently put it, between me and Addison is over."

"So if I call you—"

"I'll be right over, ready and willing." Mark smirked.

She paused. "I can't start something with you," she told him pointedly. There was a long moment of silence and Mark had a feeling that he wasn't getting anywhere until Meredith gave him a stern, amused look. "This is a business arrangement."

Mark gave her the McSteamy face, glad that she was lying when she said she was immune to it. "That makes it sound cheap," he protested. "It is what it is. No labels and no definitions."

Meredith downed the rest of her drink and leaned across the table. Mark took the hint and closed the space between them.

……….

Derek rushed into Joe's bar, feeling optimistic and ready to make things right with Meredith. He paused in the doorway, his eyes searching for her. His breath froze in his chest when he saw Meredith leaned over a table, kissing Mark of all people. His fists automatically clenched and he felt the familiarity of the situation weighing down on his chest, making it impossible to drag in a breath.

He was Derek Shepherd. He was Derek Shepherd. That should mean something. He pushed his way to the top, only for his marriage to be ripped apart by the very same man that was currently making out with his sort of girlfriend in a bar. The bar where they met.

Only Joe saw him turn and almost stumble out of the bar without talking to anyone.

……….

"You are crushing me," Meredith's muffled voice exclaimed.

"I'm sorry," Mark said, maneuvering so that his weight wasn't all on her. "It's been a little while since I've had sex in the back seat of a car."

"We haven't gotten far enough for this to be called sex," Meredith said, frustrated.

"Well, if you would stop complaining," Mark muttered.

"I'm sorry," Meredith said sarcastically, "I'm not drunk enough to have sex in that bathroom, and you are like three times my weight. You can't just lay on me like that. Your impatience is killing my mood."

"First of all, you're the one that was so impatient. Isuggested a few more rounds of drinks. Second of all, I wasn't just laying on you."

"This wouldn't be so hard if you would just—" Meredith tried to move her leg but she stopped when Mark groaned. She rolled her eyes when he pressed closer, able to feel just what her leg was rubbing against. "You're going to have to," she pushed her tennis shoe clad foot out the partially open window and tried to hook it there so she could pull herself up, "work with me here."

"I'm trying to work with you. It's just a little difficult when you are so damn wiggly." Mark pushed himself completely off of her. "We should've tried this with you on top." He was uncomfortably crouched over her left leg, her right hanging out the window and practically resting on his left shoulder.

"Ugh." Meredith disentangled herself from Mark and the window and climbed over the seat into the driver's seat.

"Where are we going?" Mark asked when Meredith started the car.

"I'm dropping you off at your hotel and I'm going home."

"Hey!" Mark thought of climbing over the seat but quickly discarded that idea. He opened the back door just as she pushed the gas. "Can you hold on for one second?"

Meredith slammed on the brakes and sat impatiently while Mark wrenched open the driver's side door and climbed in. As she sped out of the parking lot, Mark's wandering hands found their way into her pants. "Mark," she hissed, removing one hand from the steering wheel and grabbing his wrist.

Mark grinned and leaned into her. "Concentrate on the road," he breathed in her ear. He slowly removed her hand from his wrist and put it back on the steering wheel, keeping his hand over it and one eye on the road. When he was certain she wasn't going to stop him, he continued what he started.

Meredith cursed, her hands gripping the steering wheel so tightly they turned white. She unconsciously pressed on the gas as Mark's fingers wandered farther downward. "Mark," she said, her voice choked. "I can't drive when you do that."

Mark glanced at the road in front of them. "I think you're doing just fine," he said, pushing her panties aside.

Meredith arched her back and gasped. "Mark," she said urgently. She glanced at him, noticing the devilish spark in his soft eyes. She glanced in her rear view mirror and switched lanes, pulling onto an exiting ramp. She pulled over on the side of the road and shut the car off.

Mark grinned when she reclined her seat. He continued his ministrations, happy that he was able to kiss her without the possibility of a collision.

Meredith moaned, pulling him closer. She squeezed her eyes closed, her grip on the back of his neck tightening as his fingers slipped inside of her.

Mark hissed when he felt her blunt fingernails pierce his skin. Their kisses became more demanding as Meredith was pushed closer to the edge. She wrenched her mouth away and slammed her head back into the cushion of her seat, her eyes closed. Mark kissed her neck, allowing her to pull him closer while she pushed herself into his hand. He was immensely uncomfortable with his half-kneeling position, trying not to crush her as she continually tried to pull him closer.

Meredith clawed at his upper back and neck as she was finally sent over the edge. She loosened her hold on him and opened her eyes when his hand was free of her pants. She lazily turned her head to look at him. "We should probably have a talk about when and where," she told him.

"Unfortunately, our mouths are going to be otherwise occupied."

"We tried this," Meredith reminded him. "If you could just wait—"

"Well, I can't so we're going to have to make this work."

Meredith sighed deeply. "It shouldn't be this hard," she said.

"Come on. Whose first time together is perfect? If we can manage some synchronized movement then we can make this work."

Meredith groaned. "This is irritatingly humiliating," she muttered. She turned toward Mark and nearly fell on him when she moved her left leg so that it was between his and awkward stood up. He moved his seat back as far as it would go and helped her reposition herself in his lap.

"See? This can work," Mark said optimistically.

"Less talk, more action," Meredith murmured. She pressed herself against him, her lips moving over his.

Mark's hands slid up her sides and back down to her hips and shifted her slightly closer to him.

Meredith leaned into him, pushing herself as close to him as possible with their clothes on. Mark broke the kiss long enough to pull her shirt over her head. Their mouths fused together, hands frantically wandering. Meredith's fingernails scratched his chest and she ripped his buttons trying to get them undone. He pulled his black skin tight undershirt over his head and she unhooked her bra.

Mark groaned when her hips started rocking ever so slightly, increasing the friction between them. "If you keep doing that," he whispered against her neck, "then this is going to be all over before it starts."

Meredith smiled and tilted her head back, stilling the unconscious rocking of her hips. She lifted herself up when he started pushing her pants off her hips. "I don't know how we're going to work this," she grunted.

"Lean back," Mark said.

Meredith leaned back, gripping the dash and dutifully pulling her leg up when Mark tugged on it. When her pants were successfully off, she leaned back into him. "I'm impressed," she said laughingly as he kissed her.

"You have to be smarter than what you're working with," he countered breathlessly when she pulled back.

Meredith trailed kisses along his jaw as her hands started fumbling with his belt. "I'm completely naked and you're still practically fully clothed," she complained.

Mark stilled her hands and finished unbuckling the belt. She slowly unbuttoned his pants and dipped her hand into his boxer briefs.

Mark hissed when first made contact. "Stop," he rasped when she slowly stroked him. He helped her push his boxers and pants low enough on his hips so that he was free. He pushed himself up, unintentionally brushing against her heat as he fished for his wallet. He pulled out a condom and she helped him roll it on.

Meredith bit her lip as she slowly rose above him, her heart beating as his hands drifted down to her hips to position her. She helped guide him and she sank down with a groan. She involuntarily clenched around him and he growled low in his throat. She kissed him with a bruising passion as they started moving. His grip at her waist was bruising as their movements became more heated and forceful.

Mark almost lost it when Meredith's hand gripped the short hair on the crown of his head. His teeth raked across her neck and she cried out in pleasure and pain.

Mark reflexively bit down on the soft flesh where her neck met her shoulder when her inner muscles tightened around him.

Meredith's fingernails scraped across the back of his neck as her hand tightened in his hair. She rode out the waves of her orgasm and collapsed against him.

They laid there for several minutes, allowing their breathing to even out before Meredith pushed herself off of him. "Ugh, we didn't put much thought into this," she said as she carefully moved back into her seat. "I'm going to have to clean this car from top to bottom." She reached between Mark's legs for her pants.

Mark groaned at the sight of her between his legs. "Hurry up," he begged.

Meredith grinned when she sat back up. "Ten minutes," she promised, pulling her pants up. She reached into the backseat for her shirt and pulled it over her head. "Better look halfway decent before we get there. Izzie's home."

A/N: OMG. I just wrote that. Seriously. I wrote that. That's so appalling. Lol. I had an insane amount of fun writing that. I laughed just about the whole time, but it was SO great.
