A/N : I know this is just evil, but I had to write it. -lol-
Addison drew the streamers out from the back of her car, gathering them into a bundle of her hands. She sighed, not really sure why she was doing this. Meredith Grey is her college, a surgical intern, technically, one of her students, if she dare say. And she was the ex-girlfriend of her husband. She wasn't even really sure if she had considered Mark as her boyfriend during the period of the affair, but that wasn't the point. It was Meredith Grey's birthday and the Shepherds have gotten the morning off, coordinating with the rest of the interns to decorate Meredith's house as a surprise to her.
Derek placed the large cardboard box of party decorations on the floor as he shut the booth of the car with a soft bang. She pulled out the stack of party hats with a laugh, imagining what everyone would say if they were made to wear something that only a party for 5 year-olds would require. She stack them on the top of her head, then drew out a bag of decorations and shut the car's door with a swing of her hip.
The both of them entered the door with the key given to Derek from Izzie and settled the things down on the floor. Derek shut the door behind him as Addison placed both hands on her hips with a sigh, her green eyes surveying the house. The house that belonged to the daughter of her mentor.
"So, where do we start?" Derek asked, knowing that between the both of them, Addison was better in decorating houses than he is. She bit her lower lip in thought for a moment, then pointed to the high corners of the wall. "Streamers, there. Get a ladder and I'll pass you the colors. I don't want you to turn this into a clown house." she said. Derek looked up to the direction she was pointing at and scratched at his hair.
"I'm not that tall, honey." He commented, "And I don't even know if Meredith has a ladder." At that, Addison turned to him with a shrug. "We can stack chairs."
Derek took a step to stand beside her, his eyes fixed on the high wall as he folded his arms in front of his chest. "You know, I was thinking maybe I can do something lower." he started, ignoring the frown that his wife was giving him. "Like, I don't know... you?" he said, then turned to face Addison, his arms sliding around her waist.
Addison gasped in surprise at the contact, then started to bat him away, but he held on, a grin on his face. "Oh, we're not doing it here, Derek." she warned, but he only nodded, a hand sliding up her thigh, bringing her skirt up to her waist. With another hand around her neck, he pressed her down to him for a kiss. Addison felt the passion and the heat seared through her body, her lips parted to kiss her husband back. But that was only so far she allowed things to happen. It was Meredith's house. She pulled away, placing her hands on his chest to keep their distance.
"It's Meredith's house." she reminded him. But he only shrugged.
"I don't care." he said. "Do you?"
But before she can respond, he hoisted her up to the railings of the stairs and pulled her down for another kiss. She wrap her long legs around his waist, kissing him back with similar desire. He smiled when their lips part for a brief second. Wrapping his arms around her waist, he carried her towards the living room couch, but not before a moment pressed against the wall near the kitchen. Blindly, them gropped around, finally landing onto the couch. From under her skirt, he tuck her shirt out, then unzipping the skirt. She paused, looking into his eyes for a moment before her hands shifted from his back and down to his chest, her fingers working to undo the buttons on his shirt.
They're doing it in Meredith's house. And the couch will not be the only thing that they will be on.
