Author's Note: I would like to thank dropdeadnina for encouraging me to do something with this story. I started it forever ago and for some reason never finished it. Since I can't seem to do anything right with my newer stories I figured I would revisit and finish an older one. My goal is to wrap up all my Grey's Anatomy stories so I can close that chapter of my life. I used to love this show and writing for fellow fans. Lately I have been disappointed in the show and seem to be a disappoint to readers. Well, alright. I'm shutting up now. I do hope those of you who take the time to read this enjoy it.

Chapter One

The Proposition

"I need a favor."

Slowly, Dr. Mark Sloan set his mug of coffee on the table in front of him. He crossed his arms and stared up at Dr. Lexie Grey. She gave him a smile that was a bit to bright, even for her. He quirked one eyebrow up, waiting for whatever favor she wanted to ask. With Lexie it could be anything from a piece of gum to asking to scrub in on his next surgery. He'd probably say yes to either. They'd formed an odd sort of friendship; one where he told her what a loser he thought George O'Malley was and she told him to grow the eff up.

"Finally going to ask me for that mind blowing orgasm?" Mark teased. He couldn't help it. Ever since she had told him about George accusing her of sleeping with him it had become a habit to ask if she was ready to make it a reality. He wasn't serious. She was to sweet and innocent for someone like him. He was as jaded as they come. He wasn't going to be responsible for making Meredith's little sister into a cynical, man leery bitch. Let George or some other douche bag do the honors.

A crimson stain seeped into her usually pale cheeks and her slender fingers knotted in the fabric of her scrub top. "What I mean is, Alex forgot about me." Mark crinkled his brow. What the hell was she talking about? "When we had to list who we slept with," she explained. Her teeth drew her lower lip in, a sure sign she was on the verge of a nervous ramble. "He forgot about me. In front of George. And last night George made a joke about it. It's not the least bit funny and I don't want to be the girl whose so lousy in the sack that guys just forget about her."

"You want me to kick his ass," Mark volunteered, trying not to chuckle. In a way he could understand why George would tease her. Alex forgetting he slept with her was the sort of thing that had to be laughed at. It was also something Mark could understand. Girls like Lexie were sweet and cuddly. Sweet and cuddly seldom amounted to freak in the bed.

"No!" Horror widened her eyes. "No!" She shook her head, strands of her medium length brown hair coming loose from the sloppy ponytail she wore low on her neck. "I want you to...you know..." She cleared her throat. No. He didn't know. At least he didn't think he knew. The only thing that came to mind was that mind blowing orgasm he was always teasing her about, and he knew there was no way she was asking him for that. His confusion must have shown because she leaned close, her eyes darting in both directions before locking with his. "I need you to be honest with me."

Relief shot through him. He could be honest with her. It was something he could handle. For a moment there he had been afraid she really was asking him to have sex with her. "I'm always honest with you," he smirked. It was true. If there was one person he was honest with, even when he knew it would piss her off, it was Lexie Grey.

"I know. That's why I'm asking you." A tentative smile teased her full pink lips as her lashes lowered against the apples of her cheeks. His heart twisted a little. There were times it really sucked that she was Meredith's little sister and he was Mark Sloan, a known man-whore. Anything other than friendship would never work between them. They were just to different. Unfortunately his dick didn't seem to understan that because she was to blame for a vast majority of his hard ons. Some friend he was. "I need to know if I'm really that bad."

Ah shit. His first hunch had been right. In the past he wouldn't have hesitated to take her up on the offer. Before she could rethink it, he would have had her naked in the nearest on-call room. He was turning over a new leaf though and new leaf Mark was fighting to be a good friend. It felt like a losing battle. Especially since he could feel an erection straining against the fabric of his navy blue scrub pants. Down boy, he thought. There's not going to be any action. Not with her. "What does that have to do with me?" It was best to play stupid. To pretend he didn't have a clue that she wanted him to act as an objective third party and tell her if she was lousy in the sack. There was no way in hell he was going to be that third party. Forget that they were friends, Derek would kill him, by order of Meredith.

"You're Mark Sloan." The way she said it, it was almost as though she thought that explained it all. He guessed in a way it did. He was Mark Sloan. Lexie wasn't deaf or stupid, which meant she'd heard the rumors of his prowess in the bedroom. "And you're my friend. You'll be honest."

"What exactly are you asking Lexie?" Scrubbing a hand down his face, Mark let out a gust of air. The question was just another way to avoid her bombshell. He already knew how she would answer it. She wanted him to fuck her. If she came right out and asked him, he didn't think he would be able to say no.

"You're going to make him actually ask you, aren't you?" Hell yeah he was. She didn't have the guts to do it. Which meant he wouldn't be put in the predicament of ruining their friendship. She splayed her fingers on the table top and leaned forward. A lock of her hair fell across one eye, giving her a sexy-in-the-girl-next-door-kind-of-way look. "Alright. You win. I want you to have sex with me and tell me how bad I really am."

Well damn. The girl had bigger balls than he had thought. She had actually come out and asked. Which meant he would have to give her an answer. Yes, his erection cried. Yes, yes, yes! "What do I get out of it?" The question was more of a stalling tactic than a serious inquiry. Her eyes darkened with hurt while the wheels in her head started to turn. She was trying to come up with something to offer him. Something other than herself. He muttered a curse word under his breath. He hadn't meant for her to take the question that way. He hadn't meant to make her feel worse than she already did. And she had to be feeling pretty low to come to him the way she had.

"I'll teach you how to be a nicer person," she said after a while.

"Let me see if I have this right. In exchange for training you to do sexual tricks that will blow O'Malley's mind, you're going to teach me how to be nicer?" It was almost laughable. Almost because she was dead serious. She thought he needed to learn how to be a nicer person. Maybe she was right. A nice guy sure as hell wouldn't be giving her proposition serious thought.

"I think that about covers it," she answers weakly. Her throat visibly worked up and down. When she raised a hand to brush back the hair that was hanging in her face it was trembling. "So...we're agreed? You'll teach me?"

Teach her. When Richard Webber had asked him to be a teacher, Mark didn't think this was the sort of teaching the man had in mind. Never the less, it was the sort of 'teaching' that went on all the time. Burk and Yang. Derek and Meredith. Addison had even shagged Karev before high tailing it to Los Angeles. So why shouldn't he? The more he thought about it, he could be doing the nice guy thing. A nice guy would help their friend out. Wasn't that all Lexie was asking for anyways? For him to help her out? Weak excuses. Every last one of them. He was a weak man though, and there was nothing in his 'new leaf' handbook that said he couldn't use his skills to help out a friend. "This will change things, you know that right?"

Lexie hesitated before nodding. "I can't be that girl. I can't be the girl whose forgettable," she whispered.

He wanted to tell her she couldn't be forgettable if she tried. Instead, he told her to be at his hotel room at eight o'clock that night.
