A/N : Train rides will never be the same again. -grins- Here's one by Lisa (McDreamy) aka McMarried9 from The Incision!
Addison's head rested on Derek's shoulder. It was nearly two in the morning, and they were riding the subway back to their hotel room. The Chief had sent them to a medical conference in Manhattan, and that night had been the closing night cocktail party. Derek was wearing a black suit, although the shirt was now unbuttoned several buttons and he was no longer wearing the tie, and Addison was wearing a form-fitting black cocktail dress. By the looks they were getting from the few other people on the subway, they could tell that their formal wear was out of place.
Derek leaned his cheek against the top of her head, and said underneath his breath, "I'd really like to take you right now."
"We're on the subway Derek; there are people here," Addison countered softly and patted his thigh.
"I'm sure they'd avert their eyes if we started doing something," He began running the hand that was cupping her knee up her thigh to the hem of her skirt.
"Derek! Stop!" Addison hissed, slapping his hand away.
"If you didn't want me to want you, you shouldn't have worn something so hot," Derek stood up and leaned against the pole in the aisle in front of Addison.
Addison gave him a small smile, "You think you have that shirt unbuttoned enough? I can see your chest hair."
Derek sent a sideways glance to the people at the other end of the car; they were paying no attention to the Shepherds. He took the opportunity to lean over, placing his hands on each side of her thighs and his head next to her ear.
"Does that turn you on?" He whispered, being sure to breath heavily against her ear.
"A little bit," Addison grinned and put her finger on her chin and guided his lips to hers.
When Derek pulled away from the tender kiss he frowned, "Just a little?"
Addison chuckled and opened her mouth to respond, but the subway lurching to a stop interrupted her. Derek straightened to his full height and started for the door. But he stopped when he realized Addison wasn't following.
"Addie?" He wondered, "This is our stop."
"What if we…" She trailed off, lifting her eyebrow suggestively.
"Are you serious? Because I was kidding," Derek coughed at the suggestion; when he had broached the idea, he had never imagined Addison would agree.
"We're alone," Addison motioned to the empty car. She stretched her leg along the bench and looked at him, "Are you going to just leave me here?"
Derek's eyes traveled up her leg to the bottom of her skirt, which was riding far up her thigh, and he needed no more convincing. He crossed to her in two long strides and captured her lips in a kiss with so much force that it threw her back so she was lying along the bench.
The subway lurched to a halt at the next stop just as Derek was standing and redoing his pants and pulling on his jacket, he smiled down at his wife who was still laying on the bench, "We're going to have to walk a couple of miles to get back to our hotel."
Addison stood slowly and adjusted her skirt, she leaned over to whisper his ear as they stepped off of the train, "We could take another train back to the station."
Derek gave a deep chuckle, "Oh that is definitely what we are doing."
