Meredith

The lights are on, this means they are home. So much for being undetected. Maybe they'll both be in their rooms. No, I just saw Izzie in the living room. Alright I might as well go in and get this over with. I am sure he is now wondering why we are still sitting in the car.

Meredith smiles at Mark and they both get out of the truck. She opens the door and of course Izzie spots her right away.

"Hey, Mer, I made dinner," Izzie cheerfully says, not even noticing Mark walking through the door yet.

Do we eat dinner or just go upstairs? I am hungry but I think it would just be too much right now. "No…thanks, Iz, we are just going to go upstairs."

Izzie quickly looks to Meredith's left to see Mark standing there. Her eyes get wide and she can't hold in her smile. "Ok, Mer, have fun."

Oh god, Izzie how embarrassing. I gotta get to my room before George sees. Maybe I should have asked Mark if he wanted to have dinner. Where are my damn manors? That was so rude of me. He doesn't look like he cares much.

They walk into Meredith's room without any more interruptions. They both sit on the bed leaning their backs on the headboard. At first there is silence, not awkward silence, just silence.

No one is saying anything. I should say something. What do I say? Why isn't he saying anything? There has to be something to say. God, Meredith, stop being an idiot and just talk to him. Talking is important for any relationship. Wait we aren't in a relationship. I don't really know what this is. I really really suck at this.

Finally Mark speaks up, "So um, I'm going to work at the hospital now."

What? Wait this hospital? My hospital? With me? As my boss? This can't be happening. "Seattle Grace?" I think my voice just squeaked. Way to go, moron.

"Yeah I met with Richard today and he offered me a job and I accepted." This is good news right? It's good, it's what I wanted. It's what I wanted and now I have it. He's going to stay. I think I am happy.

"Great." Is that all you can say? You're hopeless. He's looking at me. I can't read him. What is he trying to say? Those eyes, there is dirty in those eyes. I don't think I want to talk anymore. Talking is overrated. "Let's just fuck."

Mark

The roommate thing really isn't a problem. It's not like we are going to be hanging out with them or anything. We are heading straight to the bed room. We have been sitting here for an awfully long time. I wonder if she is getting second thoughts. Maybe she doesn't want them to know about me. It's too late for that, I just saw someone walk by the window. I think it was that hot blonde.

Meredith smiles at Mark and they both get out of the truck. She opens the door and of course Izzie spots her right away.

"Hey, Mer, I made dinner," Izzie cheerfully says, not even noticing Mark walking through the door yet.

Oh god, I hope she says no. I don't care if I haven't eaten all day, I do not want to get stuck having dinner with anyone tonight. I am here for one person only. "No…thanks, Iz, we are just going to go upstairs." Thank you so much.

Izzie quickly looks to Meredith's left to see Mark standing there. Her eyes get wide and she can't hold in her smile. "Ok, Mer, have fun."

Oh I intend to. Do you think she wants to have sex tonight or if she actually wants to try getting to know each other? Is this considered a date? I don't know what this is. I almost forgot how I ended up here in this position. We were joking about sex…that settles it, we are having sex tonight.

They walk into Meredith's room without any more interruptions. They both sit on the bed leaning their backs on the headboard. At first there is silence, not awkward silence, just silence.

Well this is awkward, no one is talking. I wonder what she is thinking. She is probably just as nervous as I am right now. Someone should definitely say something and it doesn't look like she will be the first to speak up. What should I say? I guess I should tell her the good news. I just hope she thinks it's good.

Finally Mark speaks up, "So um, I'm going to work at the hospital now." How about next time don't stumble over your words, you asshole.

"Seattle Grace?" Ha, she is nervous. Her voice just went like 5 pitches higher. It was adorable.

"Yeah I met with Richard today and he offered me a job and I accepted." We don't have to tell her it was my idea. She doesn't need to know. It's not important.

"Great." Great? GREAT! She's happy. That's good that she's happy I am staying. Thank god I don't have to worry about that again. She looks so beautiful tonight. I could get lost in her eyes forever. Ew, who says stuff like that. Snap out of it, man whore. "Let's just fuck." I thought you'd never ask.

The whole day Mark had to give himself a pep talk. He knew there would be sex but he wanted to enjoy it this time. It's not that last time wasn't enjoyable but they were both drunk and it was sloppy and dirty, which he didn't mind, but he wanted this time to be special. He wanted to run his hands up and down her body to feel every bit of her. He wanted to memorize her curves with his fingers. He wanted to be able to go slow and make the ecstasy last all night. A man like Mark ordinarily wouldn't want these things but then again Meredith isn't just some ordinary girl. For the first time he feels he has found his equal. Then she said fuck me and all of that went out the window.

He tries to move slowly at first. Well he has to get her naked first. He quickly tears her shirt off over her body then he works on taking his off next. She pushes him down on his back and hovers over him. She begins to kiss him slowly. He had never felt a kiss like this before. It was so soft but it sent sparks through his body. He runs his hands up and down the sides of her body as he kisses her back. She strategically puts her knee right in between his legs and up against his cock. She knows exactly what she is doing. Giving him that little contact that makes him fully hard. She lowers herself and deepens her kiss. Her breasts touch his chest and he wraps his arms around her. He can't allow her to call the shots anymore. He wants her.

His tongue escapes his mouth and enters hers. He pulls it back out. It's his turn to tease. He runs his hands down her body once more. Reaching for her ass he puts his down her pants and pulls her unto him. His hard cock rubs against her. Always having contact with her skin he moves his hands to the front of her pants where he frantically works on unbuttoning and unzippering her jeans. While he pulls her pants with her panties down she rubs him through his pants. He is caught off guard that he almost couldn't get the pants all the way down. She kicks them off the edge of the bed and onto the floor.

Mark grabs her and turns her over onto her back. He lies down next to her on his side and continues kissing her. His hand begins at her breast, caressing it slowly. His hand slowly travels down her body and he slowly rubs his finger down her now wet lips. She lets out a moan and her kiss becomes more desperate. She reaches for his cock again. His pants are in the way. She tries to undo his belt but she doesn't get very far because he starts to massage her clit. She rocks her hips up and down with his movement. She needs him, she wants him. He can't stand it anymore himself so he quickly pulls his pants and boxers off.

He hovers over her with his fully erect cock teasing her entrance. He grabs it in his hand and runs it up and down to tease her. He can't handle much more himself but the look on her face is well worth the torture. She finally has enough and wraps her hands around him and pushes him into her. They both moan and yell out in pleasure as he quickly enters her. He quickens his trusts almost immediately. All sense of romance or passion leaves him. The more she screams the harder he thrusts and deeper he goes the more she wants it. Harder harder deeper deeper he goes. She wants more but he couldn't possibly go harder. He reaches down to massage her clit as he thrusts into her. She can't hold it in anymore. Any thoughts of anyone else being in the house goes out the window. With every movement of hers it seems her screams get louder and louder. Mark lets out a loud moan himself as he explodes inside her. She is left flustered and even he is surprised in how amazing that felt. He rolls off of her and onto his back next to her. They just lay there in silence with smiles on their faces. Meredith looks to him and Mark looks to her. She says the first thing that pops into her head, "Thank you."

Meredith

I can't even concentrate. I can't get the image of his penis out of my head. It is dirty thoughts like these that get surgeons in trouble, I swear. How can I be expected to concentrate on my work when that sex god is walking the halls of this hospital? I hope they stick me with Burke or something, I don't know, anything but Mark. I can't face Derek today either. He is going to see right away that something is up. I don't know how much longer I can hide from this. Crap, I think Dr. Bailey is talking to me.

"Yes, Dr. Bailey, Dr. Shepherd it is." She does it on purpose, I just know it. Does it look like I can handle Derek today? I don't think so. I am a mess. My hair looks like shit and she looks beautiful today. She always looks beautiful. I probably would've chosen her too. There he is now. I'm not ready for this. He doesn't look happy. Time to pretend to smile. "I'm with you today."

"Good. Ok. Please send Mr. Richards in 2337 up for a CT to see if the swelling went down." That was weird. No looks. No smiles. No emotions. What the hell is going on?

"Are you ok?" Why should you even ask? He doesn't care about you. Why should you care about him? Because he does care and so do I. Well just stop it. It's over. "You just don't seem like yourself, that's all."

"Mark is still here." Act surprised, you're supposed to act surprised. You're not supposed to know he is still here. You're definitely not supposed to know what he looks like naked. Why did I think about that? Now I am back to not being able to concentrate. I think I'm supposed to be angry that he's here. "It seems that the chief offered him a job."

"I'm sorry, Derek." Is that the best you can do? You're supposed to be angry with him about it. That's what friends do. They comfort each other. Who am I kidding? We will never be friends. Not after he finds out. "That really sucks." That was a pathetic attempt at anger. "I'm going to get that CT now."

Mark

I wonder if she gives good head. She seems like she is good with her tongue. From what I can tell from the two times I have been with her she is very good with her mouth. She's definitely experienced enough to give me a run for my money. She may even be better than Addison. Speaking of Addison, I should start counting how many times Addison or Derek give me a dirty look today. I'm a bit surprised that they're not acting more adult like about this. No. Wait. I'm not. This is Addison and Derek, and when it comes right down to it they're exceptionally child like when they don't get their way. Anyway, I need to give this young man some directive I suppose.

"Dr. Collect, I need you to do something very important for me." I think that's his name. What a weird last name.

"Karev, Dr. Karev." That's not much better.

"Well anyway, Dr. Correnz, I need you to go to this address and pick up my luggage for me." If anything is missing I am going to go kick someone's ass. I don't know if I trust the airline or this kid for that matter. How could I possibly trust anyone with the last name of Klepto. How did they even let him become a doctor?

"This is the airport." We have a genius on our hands. I should just do it myself and send this kid to the pit. No, because if I left then I wouldn't be able to stare at Meredith all day.

"Yeah I know. That's where luggage usually is. Now go." That nurse is kind of cute.

Meredith

If I think about swelling brains I go right to thinking about swelling…other areas. Derek says "I'm going in" and all I can think about is sex. I can't function like this. Everything reminds me of last night. I need something to get this off of my mind. Think, Meredith, think. Craniotomy. Ten blade. Incision. Running stitch. I'm doing it! Suction. Sucking. Derek. Wait, Derek? Oof.

Meredith walks right into Derek.

"Sorry, my mind is other places today." And you do not want to know where those places are. Why is this happening to me? Why did I sleep with Mark? This is going to get much more complicated than it already is.

"I can tell. Anything you want to talk to me about?" Not hardly.

"Not at all." Ok that was not the way you were supposed to react.

"Come on, we're supposed to be friends. Friends tell each other things."

"Friends don't tell each other everything, Derek. I am fine. For the first time in a long time I am actually fine." Wow. I actually am. Stairs! There are stairs here. Pay attention, Meredith. Oh look, there's Izzie…with a smile on her face. This can't be good.

"Hey Mer, I was thinking that after last night we should probably change his name to McScreamy." Holy shit, Derek is still here.

"What is she talking about, Mer?" Oh god, bad bad bad.

"Nothing!"

Meredith grabs Izzie by the arm and quickly escorts her out of the stairwell.

"You haven't told him yet, have you?" NO! Why would I? Freaking crazy barbie.

"No and I don't plan on it." I knew it was a bad idea bringing Mark home like that. Could it possibly get any worse?

"Come on Mer, McScreamy was funny. You have to admit it." Meredith starts giggling.

"Ok, fine, it's funny. Just so wrong."

I tried so hard to be quiet. It may be impossible. He knows just the right things to make you scream. Stop. You can't think about this right now. You have a job to do. What's a quick fuck session in an on call room going to hurt any? Don't start thinking that way. It's too risky. Nobody else can find out about this. I can't afford for the whole hospital knowing. I can't hurt Derek that way. It's going to be my little secret. There he is. Why does he have to look so damn sexy in scrubs? You're weak…much too weak for this.
