A/N : So...another one of Addie lusting for Derek instead of the other way round. You want your man to play football now? I think I do! This is by Lisa (McDreamy)!

Addison Shepherd did not play football. It was just a testosterone filled slam fest in which men tried to prove whom was the manliest. Addison didn't even watch football; there were way too many rules to ever understand what was going on.

Addison's dislike of football was the reason she was sitting with Derek's youngest nieces and nephews twenty yards away from where he was playing a game of football with some of his sisters, nephews and brothers-in-law. Her attention was not on the competition, only on the children playing at her feet.

She didn't lift her eyes from the children on the ground until Derek called out, "Hey, Add!"

Her breath caught in her throat. Derek was wearing a pair of baggy black athletic shorts, tennis shoes and absolutely nothing else. His defined, but never large, muscles rippled from the exertion he was forcing on them. Sweat glistened along his muscles and chest and he mopped his sweat soaked brow with his arm before flashing her a grin.

"What?" Addison tried to muster a look of indifference on her face and silently hoped that her desire for Derek wasn't plastered across her expression.

Derek's breath was heavy from the exercise, and Addison couldn't stop her mind from wandering to other times when Derek was reduced to panting and breathing heavily. He glanced back to the game that was stopped behind him before asking, "Will you run in and grab me a water bottle?"

Addison stood slowly and glanced down at the children, "You have to keep an eye on them, then."

"Will do," He agreed.

She turned and walked into the house. Her mind was suddenly full of completely impure thoughts. Derek's body was something she had always enjoyed; when it looked that good, how could she not? She was usually able to keep thoughts of doing unmentionable things to his body at bay. But just thinking about how completely sexy he looked, all worn out from the competitive game, made Addison weak at the knees.

It took several steadying breaths before Addison would allow herself to return outside. Taking Derek and having her way with him would not be appropriate at a Shepherd family get-together. So, water bottle in hand, she returned to the football game as composed as she could muster.

After giving Derek the bottle, she settled back into her chair near the children. But now she was paying much closer attention to the game. Derek had been designated as his team's quarterback, and, when he pulled his arm back to throw a pass, his back turned to her slightly, highlighting the rippling muscles along his back. She closed her eyes momentarily and pictured digging her nails into the skin on his back.

The dirtiness of Addison's thoughts increased exponentially when she opened her eyes. Derek had just broken out into a run and, once again, she was provided with a view of his body. Just as he was reaching the designated end zone, Derek's eldest nephew threw his arms around Derek's waist and pulled him down. Derek's shorts rode far up his leg, and Addison was provided with a view that stopped just before his groin. She groaned softly to herself. If Derek kept this up much longer, Addison's self-control would go out the window.

She needn't have worried, for according to the nephew, that down ended the game. Derek jumped to his feet and walked away from the game. Addison followed him, intent on satisfying her urges. He was several paces ahead of her, and she only caught him when he entered the bathroom. She discovered the door was locked when she attempted entry, but she would not be deterred.

"Derek, it's me," She knocked softly on the door, "Let me in."

Addison's lips attacked his the instant he opened the door. He stumbled backward at the force of her kiss and soon they were both in the bathroom. She kicked the door shut behind her.

"What is this for?" A grin played on Derek's lips.

Addison locked the door behind them and pushed her husband against the wall. She pressed her lips back to his in a passionate kiss that stole both of their breaths away.

"You are so hot," She murmured, pulling her lips away from his and beginning a trail of kisses down his front, starting at his neck. She could feel him reach for the towel rack to keep his balance when she stopped her line of kisses at his navel and teased it with her tongue.

"Oh, god," Derek gasped as her hands slipped underneath the waistband of his shorts.

He reached down to pull her back up to his lips. Taking control, he hoisted her up by the back of her thighs and settled her on the counter near the sink. He nipped at her ear lobe, breathing heavily in her ear. Addison rolled her head back on her neck and ran her hands up his muscular arms. As Derek's hands found her chest, she dug her nails into his back.

Things were moving too slow for Addison, who had been thinking about this for far too long, and she pushed his hands away and slipped out of her blouse. Derek grinned, his lips capturing hers as he helped her shed her clothing.

Sometime later, Addison leaned back on her arms as Derek rested his head on her chest. She smiled down at him, "That was exactly what I wanted."

He chuckled and pressed a soft kiss to her lips, "What? To get soaked in my sweat?"

"Well, now I have to take a shower with you," She gave him a mischievous grin.

"Is that so?" Derek stepped away to turn on the water and threw a glance back at her, "Maybe I'll have to play football more often, if this is your reaction."

Addison nodded and slipped from the counter. She walked to him, wrapping her arms around his waist, "I think I might like football."

"I thought you liked me?" Derek pouted playfully.

"Oh I do," Addison pushed him into the shower and fused her lips to his.
