Meredith woke up Monday morning feeling great. Her and Derek were happy and Her 18th birthday was only a month away. She didn't know what to do for it. She really should have a party and she knew Christina would push for a party but she really just wanted to spend the night with Derek.

Jumping out of bed she headed for the shower. She jumped out of the shower and got dressed in her black mini and a couple of tank tops. It was looking to be a beautiful day. She headed down to her car and looked over to Derek's house. His car was still there so she decided to go and say hi

She walked up to his door and was about to knock when she heard a noise behind her. Spinning around she saw Mark Sloan standing there with a grin on his face.

'What are you doing here?' A surprised Meredith asked

'I know' He simply said

'What are you talking about mark?' She said shaking her head and turning red. Shit she thought. SHIT he cant know, this is bad, very bad!

Mark just stood there smiling a cocky arrogant smile. He tilted his head and coughed a little.

'What are you doing outside Mr Sheppard's place Mer?' he asked

'Oh I'm just asking him a few questions before class, you know "geek" she laughed shrugging her shoulders

'Yeah right Meredith, I know you and Mr McDreamy are screwing around, I saw him pick you up on Saturday night, and I'm not stupid'

Meredith looked down at the ground and shifted awkwardly she was about to say something back when Derek walks out his front door and straight in to her knocking her. 'Oh my god Mer, I'm so sorry, I didn't see you, are you ok?' he reached down and pulled her up. 'Yeah' she whispered slightly embarrassed.

'Well isn't that cute' Mark chimed in and Meredith and Derek's heads shot up looking at him.

'He knows Der' she leaned in to Derek and whispered.

Derek stood there in complete shock. Shit he thought SHIT.

Trying to act calm he looked down at Meredith then up at Mark.

'It's nothing mark, it means nothing. We haven't done anything. Were just really good friends and she lives next to me so she comes over and I help her with her school work' He said. He was nervous, this could not get out. Not yet anyway, when Meredith finished school at the end of this year they could tell everyone but this could end his career. Meredith looked at Derek. He could tell she was upset with him. Her eyes were red and she was close to crying.

'So why try and hide it?' mark asked

'Obviously people wouldn't understand and I would loose my job and Meredith would be humiliated at school.'

Mark smiled 'ok well I believe you, but I need a favour from you shep if you want to keep your job'

Derek ran his hands threw his hair 'and what would that be mark?'

'Well I need good grades to get into a good college, so I expect good results in your class, and you Meredith you humiliated me on Saturday night so I want you tell everyone we slept together and that I was fantastic' He grinned

Meredith and Derek looked at each other

'Ok' they said in unison

'Good' he laughed 'Glad we sorted that out'

And with that he turned around and hoped in his car and drove off

Meredith looked Derek in the eyes 'Means nothing?' she asked

'Mer, I had to say that, if he had found out the truth, do you know what it could do to my career, I would loose my job. No one can know. It's that simple' he answered her

Meredith wiped away her tears and started to walk away she turned back around and looked at his blue eyes 'See you later Mr Sheppard' and she walked to her car and got in and drove away. Not looking back once at Derek.

Derek Ran his hand threw his black locks. This was bad, He had to sort it out with Meredith, They had to be careful. He got in his car and Drove to school.

Meredith got to school and headed into class. She Was wasn't really in the mood to be there but she had assignments to hand in so she couldn't really blow it off.

Reaching her class she spotted Christina sitting at her desk. She walked up to her and sat down. 'Hey' she said glumly

'What's your problem' Christina asked not really interested

'Oh nothing, just didn't get a lot of sleep' she lied

She looked up and saw mark enter the room. He winked at her and whispered on his way past 'you know what to do' and headed for the back of the class. Taking a seat he sat there grinning from ear to ear just watching her.

'Uh…..Chris, I have to tell you something' she said placing glances between her and Mark

Christina turned her head to Meredith and smiled 'Ok, what is it'

'Well you know how mark has this thing for me and well I was flattered and we talked yesterday and well he came over last night and we had a few drinks and well it just happened…'

Christina's eyes lit up 'YOU SLEPT WITH MARK' she screamed a little to loud

'Not so loud' Meredith hushed her 'And yes I slept with him'

'Oh my god Meredith, I thought you hated him?' she asked

She cringed at what she had to say next 'Well not anymore, he is nice and the sex was amazing' putting as big a fake smile on as she could muster.

She hated saying that, she hated lying about having Sex with him. She felt like she was hurting Derek in some way even though she wasn't.

Christina was Laughing 'My god Meredith, you are awesome, Every girl in school is going to be so jealous of you when they find out'

'Hmmmm' is all Meredith could say

'So how big was he?' she asked nudging her

'Pretty big' is all Meredith could come up with

Christina's eyes got wide again and she turned around on her seat and grinned at Mark. He just sat there grinning back. She had done what he had asked her to do now he could start telling his mates about his fake great night with Meredith Grey.

Meredith sunk down in her chair and didn't say another thing all class.

After lunch she had a free period and decided to go to the library for an hour.

Sitting at a desk she pulled her books out and started studying for Derek's class that she had at the end of the day.

She was reading a text book when she got a tap on the shoulder, She looked up to see Derek standing over her

'Shouldn't you be in class' She asked putting her head back down to her books

Derek looked around and saw no one in sight who could hear there conversation, He took a sea next to her.

'Meredith' he said trying to get her to look at him

She glanced over at him with a bored look

'Look' he said 'I'm sorry I said that stuff to mark, Your right I was a bit harsh, I just really cant have anyone finding out about us. I was trying to lead him off thinking were sleeping together. You mean something' he grinned and cocked his head to the side giving Meredith his dreamy smile 'you mean a lot'

'Maybe this was a bad idea Der, Everyone thinks I fucked mark, your career is in jeopardy, I don't want you to ruin your future just for me' she said as her eyes welled up.

'Let me worry about that' he said and rubbed his hand on her thigh; looking to make sure no one was around still

'Maybe just have a think Derek, ok. I'm going to college next year and you will still be here. Maybe we should cut our losses before anyone gets hurt' she said and a tear fell from her eye and down her cheek.

She grabbed her books and shoved them to into her and bag and started to walk off

'Mer' he pleaded

She turned around and faced him 'What?'

He had nothing to say and just bowed his head.

She turned back around and headed to her car, She couldn't be at school anymore today.

She didn't see Derek for the next week. She was Miserable. She couldn't sleep at night. All she did was go to school, avoid Derek's class and go home and sulk.

She got home Friday afternoon and headed upstairs to her room. Blaring James blunt out of the stereo she went to her wardrobe and pulled out a bottle of tequila she had stashed for emergencies. Opening the bottle she took a huge swig and sat on the floor of her room with the bottle next to her. It burned her throat and she felt it hit her stomach. Looking down she saw her phone vibrating flashing "Derek" on the screen

She turned the music down and flipped her phone open 'Hi' is all she said

'Meredith can we talk?' he asked

'Sure, come over here, my mum is working, shock surprise' she answered back.

'ok, see you soon' he replied and hung up.

She quickly screwed the cap on the tequila and shoved it back in her wardrobe. Shutting the wardrobe and heard and knock and him enter the house. 'Mer' she heard him yell. 'She went to her door and opened it and peered down the stairs

'Come up here' she called back to him.

He made his way up the stairs and into Meredith's Bedroom. He looked around her room, He had never been in there before. There were posters of rock bands plastered on the walls and a huge mirror against one wall. He looked down at Meredith who was sitting on the bed. 'You haven't been in my classes all week….'

'No' was all she said

He sat down on the bed next to her and touched her face with his hand.

'I've missed you' he said

She looked him in the eyes. He was perfect. She felt on fire when he touched her, Electricity ran threw her body and she found herself lunging at him kissing his lips hard with hers. He kissed back and put his hands in her hair. There tongues danced in each others mouths. Meredith started leaning and back and Derek followed her lead and moved in between her legs and on top of her. She felt his hard member pushing into her. She was wet she could tell. He pulled away from her lips and started un doing her button on her shirt. Pulling it away he cupped her breasts and started kissing her neck. He knew she couldn't resist him kissing her neck. It was her weak spot that drove her crazy. His kisses moved further down on to her stomach and its there he started taking her pants off. Sliding them to the ground he pulled her pink lace panties off and found her wet opening. He moved down there with him mouth and started licking her pleasure spot 'Oh shit Der' she screamed

He licked harder and faster and soon she released and her whole body tighten around Derek. 'Fuck Der, oh my god' She yelled as her body shook in pleasure.

Derek pulled his clothes off and moved on top of her again.

'Make love to Derek' She whispered in his ear and lied back on the bed. He entered her and started moving up and down 'Oh god mer, oh god' He got out.

He moved faster and faster, They both yelled in pleasure. 'Der, I'm coming, I'm coming!' she screaming wrapping her legs around Derek as she did every time after they both came. Derek followed suit and came in Meredith 'Oh fuuuuccckkk Mer' he said releasing inside of her. He collapsed on her and they lied there for a while catching there breath. Derek finally looked up and gazed into her eyes. God she was beautiful he thought. 'Mer' he whispered

'Yeah' She smiled up at him

'I'm in love with you, I feel like I've known you forever, I love you' He smiled back at her…….
