A/N: I had some minor computer problems that seem to be all worked out. I'm sorry to leave you hanging like that. But thanks for all the reviews! I love it.

Meredith moved around her room, deciding that finishing the packing she had started the day before would be the perfect distraction. She had a few weeks yet until she would actually leave to college, but there was a lot of stuff to go through. Eighteen years of memories and junk to sort out. Besides, rummaging through her closets and organizing her drawers kept her mind occupied, kept it from wandering, kept it from Derek.

They had kissed. He had kissed her. And it was without a doubt the most amazing perfect kiss she had ever experienced in her entire life. Everything that she had heard about fireworks shooting in the background when you kissed the right man, suddenly rang so true for her. She had experienced feelings and sensations she never knew she was capable of knowing.

But it was troubling and terrifying at the same time. This was Derek. The boy next door she had grown up with tagging along during the summer. He had always looked out for her but in a big brother obligatory kind of way. He was always patting the top of her head and rolling his eyes at her like she was a kid sister. Could he really be feeling the same things she was feeling for him?

It didn't seem possible, and that scared her to death. He had probably got lost in the moment. She had embarrassingly spilled her guts all about how she was a virgin, and didn't know how she'd know when she was ready, when she found the right guy. He had probably just felt sorry for her. Felt sorry for the poor little virgin next door.

Her cheeks flushed from embarrassment, but as quick as the humiliation came, it was gone replaced by anger. Who did he think he was? Was he really so cocky and arrogant he thought he could kiss her for no reason and get her hopes all riled up? She shook her head. He was definitely messing with the wrong girl.

Derek paced on the front porch. This was bad. This was really bad. All he could think about was Meredith. Since their amazing kiss last night all he could think about was her soft lips and voluptuous curves pressed underneath his own body. The way her mouth tasted. The way her hair smelled. Her soft moans that sent him over the edge. Everything about her drove him crazy. This was really bad.

He couldn't start something with her. Could he? She was Meredith. His best friend. His sister. Well she technically wasn't his sister so he decided he should most definitely stop referring to her as that. Because the things he wanted to do to her was not something you think about with your sister. Most definitely not. This was bad.

He was twenty three, almost twenty four. She was only eighteen. He had graduated from college and was now working on his medical degree. She had only just graduated high school and was about to start college. They were in different stages of life. Complete opposite ends of the spectrum. What the hell was he doing?

He wanted her and he wanted her bad. More so then he had ever wanted another woman in his entire life. And he had been with many women. Mark and he weren't labeled the most eligible bachelors for nothing. There was a reason women swooned and threw themselves at his feet everywhere he went. He was handsome, talented, wealthy, and in pre-med to boot. He could have his pick of about any female any where he went. But frustratingly, none of that mattered now. All he could think about was Meredith and finishing what they had started the night before. Over and over again.

But again, was this wrong? Was he taking advantage? He was afraid the answer was yes. But he had to see her. He had to know what she was thinking. What was going through her mind.

So he ran a hand through his hair before he stopped pacing on Meredith's porch and pressed the door bell. His heart racing as he waited for the door to open. If he could see her just one more time, maybe all his doubts would be cleared and the answers to his questions settled. Maybe, just maybe, she was feeling the same way he was.

"Meredith!"

Meredith jumped, her mother's voice the last thing she'd expected at three o'clock in the afternoon.

"Hey mom." She answered cautiously.

Her mom hadn't said two words to her since coming home Sunday night to find the carpet completely trashed from the little party that had gotten out of control. She knew Richard must have talked to her before she'd got home because her face wasn't nearly surprised or irate as she'd imagined. It was still angry, but more annoyed than anything else.

"I assume you got all your immature and juvenile behaviors out of your system and there will be no more partying?"

"Yes mam."

"Good. Since you are headed off to college in a few weeks anyways, I'm having the house completely recarpeted and painted. No memories here worth saving. They start work on Friday. You will need to find somewhere to stay for the weekend. I'll be on call beginning on Thursday and won't have time to make sure you stay out of the workers way. I've talked to Nikole and she's agreed to let you stay as a guest. Please remember that you are a guest and don't do anything stupid to embarrass me. Let's try to keep some dignity these last few weeks shall we?"

"Mother…" Meredith opened her mouth in protest, ignoring the stinging comments and degrading put downs and opting to focus on the more important situation. She was expected to stay at the Shepherds for the whole weekend? That would be bad.

"Meredith." Her mother warned.

Any argument that was to come was instantly canceled by the door bell ringing, its chime echoing through the house.

Ellis shot one last glance at her daughter before hurrying down the stairs. Meredith listened as the door was opened and her mother greeted the visitor cheerfully.

"Why Derek! What a pleasant surprise."

"Hello Dr. Grey. It's been a while. You look exactly the same as last time I saw you. Breathtaking."

Meredith groaned and rolled her eyes. He had always had a way with her grouchy mother and she had never figured out why.

"Oh Derek…you flatterer. And please… call me Ellis. You're all grown up now. Fast on your way to becoming a doctor. Have you given any more thought about what specialty you're interested in? I still stand by what I told you when you started med school. Surgery is where the fun is."

Derek laughed. "Yes... actually I have given it a lot of thought and I'm pretty sure Neurology is for me. There's something about the brain I love."

"That's great. It really is. Are you here to see Meredith? Maybe you can rub off some of your level headedness on her. That girl's casual take at life is going to be the death of me."

Meredith was now completely engrossed in their conversation.

"Oh I'm sure she'll be fine. I heard she was quite the scholar this last year of high school. And she got into all those colleges. You should be proud."

"She could have done much better. If only she applied herself. Heck, if she spent half the amount of time thinking about her future as she did throwing these ridiculous parties, she might actually be someone someday."

Meredith had heard enough. Her stomach was sick and she had to swallow the bile that rose in her stomach. She already knew what her mother thought about her. That she was a nothing, a nobody, a failure. But having her share those qualities with Derek of all people. It was almost too much.

And why the hell was he here anyways? For another easy make out session? To bond with his mother over all the crappy things Meredith had done in her life to screw it up?

She went back to her packing. Not bothering to fold the sweaters as she shoved them in the box, not caring that her photo albums and yearbooks were jammed in with her shoe collection.

A soft knock on her open door caused her to jump a little, but she didn't look up, deciding instead to busy herself with discovering the mysterious contents under her bed.

"Mer?"

"Hmmm?" She asked distracted, using every ounce of will power in her body to keep her hands from shaking and still her beating heart.

"Can we talk?"

"What about?" She asked casually, steadying her breathing as her worst fear was about to be realized. He'd come over to apologize. Last night was a mistake.

"Come on Mer. Look at me. I think you know what we need to talk about."

Meredith sighed and pushed the box aside, slowly standing and wiping her dusty hands on her jeans. Taking a breath, she finally turned to face him, immediately regretting it as they locked eyes, the intense blue making her weak in the knees.

After a long minute of awkward silence, Meredith broke the stare and crossed her room, busying herself with something on her dresser.

"So it looks like we're going to be roomies this weekend." Derek laughed.

Meredith immediately shot him a heated look, not appreciating it one bit that he could find this whole situation amusing.

"Mer… come on… please don't be like this… at least look at me. We should talk." He said frustrated, running a hand through his hair.

"Please Derek. Don't." She said, finally turning and meeting him, folding her arms across her chest. "I get it… it was a mistake… you could never think of me like that. Fine. It's okay. You don't have to explain yourself."

Meredith used her perfected "fine" face and shrugged, pretending she was completely okay with it, when in fact, her heart was breaking on the inside. She had to look away, the wetness behind her eyes threatening. Her eyes settled on a can of hairspray that needed to be returned to the hall bathroom, and she moved towards the door, eager to hide herself in the security of her bathroom.

She had almost made it past Derek's large form when a strong had was stuck out and rested on her arm, his fingers gently wrapping around her and stopping her in her tracks. Meredith immediately flinched at the touch, the sensation bringing memories flooding from the night before. Memories she was desperately trying to forget.

Derek moved his hand quickly, confused at why she had shied at his touch. He studied her face and saw fear, something that made his insides twist in agony and his heart beat in despair. Last night had been a mistake for her. He had taken advantage.

"I'm so sorry Mer."

"Don't."

"Please Mer… I didn't mean…just please… don't shut me out of your life."

"I'm not shutting you out of my life."

"So… we're okay? We're still friends?" If he couldn't have her the way he wanted, he at least needed to know they could still be friends. He needed her in his life in some way.

Something snapped in Meredith and she let out a frustrated breath and clenched her fists. "Yes Derek. We can be friends." She spat the word back at him like it was venom.

Derek shook his head, completely blown away from her sudden anger. "What is your problem Mer?! Isn't that what you want? Friends?!"

"Yep. Exactly what I want. Friends. Best friends. Your little sis." She replied sarcastically.

"Exactly. So why are you so mad?" His patience was thinning by now and he was quickly regretting agreeing to work at his dad's office for the summer. All of the sudden, he needed to be far away from the woman he wanted but couldn't have.

Meredith stared back into Derek's raging blue eyes a moment, her heart that was beating out of control from pure anger suddenly turning its rhythm to lust. She wanted to kiss him. The urge to have his lips on hers almost too great.

Derek was frustrated. What had just happened? He had come with the intentions of pursuing the actions of last night, and now they were yelling. She was telling him she was his only his little sister, and it was making him mad.

"Damnit Mer." He said, their bodies only inches away, standing face to face in the doorway. He looked away, trying to regain his composure, trying to calm the fire growing inside him.

"Go to hell." She whispered, causing Derek to whip his head around, meeting the deep sizzle of her blazing green eyes.

Derek opened his mouth in shock. He didn't know what to say. Her eyes were full of emotion, an emotion he couldn't decipher. He moved his attention down her face, past her perfect nose and settled on her pink lips. He watched as they formed a determined scowl. They opened again and more harsh words exited.

"You are such a …"

The only thing Derek could think of to stop her from uttering more profanities in his direction was to kiss her. He covered her lips with his in a sudden, possessive movement, silencing her immediately as he didn't wait for an invitation and thrusted his tongue into her mouth. It only took a moment before she was kissing him back, her teeth biting at his bottom lip roughly, tongue pressing against his forcefully. Her hands found his hair and she grabbed two fistfuls as he pressed her body suddenly against the wall, moving himself against her to press her curves against his firm chest. The kiss was heated and hot and finished the argument for them as they bit and pulled, both ignoring the pain, both not being able to get enough.

Then suddenly, as quick as the kiss had started, it was over. Meredith pulled away suddenly and ducked under his arm to hurry across the hall and lock herself in the bathroom. Derek felt cold and empty without her body next to his, without her lips pressed firmly to his. He followed and knocked lightly on the door, getting no response.

He tried for twenty minutes before giving up. Figuring it best to leave her alone. He walked down the stairs and out the door even more confused then when he had entered.
