Bad Guys

she's hot

"Mark!" Derek yelled at the handsome man walking into the hospital lobby.

"Derek! My man, how ya been?" He said as they hugged.

"I've been great, how 'bout you? What are you doing here?" Derek said as they left their hug.

"Fantastic. Do I really need a reason to come visit my best friend?"

"Guess not."

Meredith had been standing next to Derek, she was once again on his service. Meredith had recently made a mental note to at some point tell Derek to stop requesting her on his service.

"Oh I have someone I'd like to introduce you to." He said as he put his hand on Meredith's shoulder gesturing her to come forward. "This is Meredith."

"Meredith nice to meet you. I'm Mark." He said with a flirty smile.

"So I've gathered."

"Mark's my bestfriend since we were kids." Derek said.

"And Meredith you're..." He said pointing to Derek to try and figure out the relationship between Her and his friend.

"She's my... friend and intern."

"Derek, I am going to go take care of the pre-op for Mr. Johnson. Mark it was a pleasure to meet you." 

"Likewise." Mark responded as Meredith left. 

"She's hot." Mark added after Meredith was out of earshot.

"Don't" Derek said grimly.

"No?" Mark said questioning.

"Don't even think about it." Derek responded severely.

"Why not- Addison!" He exclaimed after seeing the red-head approach.

"Mark!" She pulled him into a hug, "I've missed you."

"I got to go to surgery for Mr. Johnson, Mark do you mind taking Addison out to dinner tonight. I am going to be late and don't want to skirt my husbandly duties. Also, I don't know if you got hotel but you are staying with us."

After Derek left, Mark looked at Addison.

"The intern?" Mark asked.

"I think he's falling for her."

"I'm sorry Addie."

"Thanks. Thanks for showing up."

"I'll always show up for you."

"Wish my husband had the same mentality."

Later that day, Mark caught up with Derek while Derek was waiting for a CT scan on one of his patients.

"Hey, your wife is still hot."

Derek chuckled slightly.

"So I am going to take her out to dinner tonight."

"Great, you two have fun."

"Do you want us to bring you some food for when you get home."

"No Meredith and I have plans to quickly get some food and keep working."

"Huh. Well. I guess I'll see you later tonight."

"Yea see ya."

After a long night of working, Derek finally finished his last craniometry and decided to head home. He walked into the house but he didn't see Mark or Addison. He figured they must have gone to sleep, after all it was almost midnight. He walked upstairs and stepped on a jacket. He thought it was weird that Mark would have just thrown his jacket in the middle of the hall, but he didn't think too much of it because Mark was never known as the best house guest. 

He reached the bedroom where he heard some noises. He slowly and quietly opened the door trying not to wake Addison. But once he saw the room, he quickly realized that waking her would not be a problem. Mark and his wife were naked, and Addison was sitting in his lap doing something that was certainly breaking their marriage vows. 

Derek quickly and quietly left the room. Neither of the two noticed him as they were pretty preoccupied. Derek ran out of the house and got back into the car. He immediately opened his phone.

"Hey, what's your address?"

"What? Derek what's wrong?"

"Just- What's your address. I saw Steven's and O'Malley at the hospital so I am assuming they aren't there. What's your address?"

"Um. 613 Harper Lane. Derek-"

"I'll see you soon."

He hung up the phone before Meredith was able to say anything. He drove like mad until he reached her house. It was incredibly lucky that he never got pulled over with the ridiculous speed he was driving. 

He reached her house and started banging loudly on the door. She walked down the stairs and stood still as she watched him frantically knock until he saw her. Once he saw her staring at him through the window, he stilled. She opened the door slowly.

"Derek what-"

She was cut off by his mouth pressing against hers. She wrapped her arms around his neck and opened her mouth to match him. He lowered himself slowly and put his hands on the back of her thighs and she jumped up onto him, wrapping her legs around his waist. He carried her upstairs, and into her bedroom.

He laid her down and slowly climbed on top of her and kissed her.

She pushed his head slowly away from hers, "Derek what's going on."

"I am going to make love to you."

"What- what about your wife." She said as he started to kiss her neck.

"That's no longer an issue."

She wanted to inquire more about his change of heart, but he had taken his shirt off and she was distracted.

(hola. I am pretty split on this, would you like for Mark to stay permanently or leave)
