A/N : And this is by our dear Dulchey (Dulcineah1) from The Incision. Warning. It's hot. ;)
"Ow!" Addison rolled onto her back and dissolved into giggles as Derek put a hand up to his injured forehead. She turned her head toward her husband and tried to stop laughing. "Thank you."
"You're thanking me for the most boring sex ever?" Derek asked in disbelief, resting his other hand gently on Addison's stomach.
Addison began to laugh again. "Well, babe, everyone has their off days."
"Oh yeah?" Derek demanded, propping himself up on one elbow. "When's your off day?"
Addison smiled smugly. "Everyone else has off days."
"Right," Derek scoffed, reaching over to brush a piece of Addie's hair off of her face.
"What can I say?" she laughed. "I am the best."
"You're the best," Derek teased. "I thought I was the best."
"You just said the sex was boring!" Addison protested, leaning in to plant a kiss just below her husband's ear. "If you're the best, then why would the sex be boring?"
Derek raised an eyebrow. "Maybe it was your fault," he suggested with a grin, and ducked as Addison sent a pillow flying in his direction.
Addison rolled onto her side so that she was facing her husband, her eyes dancing mischeviously. "Let me get this straight. You're saying that you're better in bed than I am?"
Derek smirked. "How much do you want to bet?"
"What do I get if I win?" Addison demanded, and Derek remembered suddenly just how competitive his wife could be. Maybe this wasn't such a great idea after all, but there was no backing down now.
Derek shoved those thoughts out of his mind. He was going to win, so what did it matter? "Let's say that the loser has to be the winner's slave for an entire day." And when he won, he was going to make Addison go camping with him, he though smugly.
"You've got a deal," Addison agreed, looking extremely satisfied with herself. Derek caught himself wondering what she had in store for him, and reminded himself that it didn't matter because he was going to win, dammit. "Whoever initiates the most exciting sex by the end of the day wins."
Derek leaned in to kiss his wife. "Deal."
Addison stifled a yawn as she strolled down the corridors of Seattle Grace. She had gotten little sleep last night, and since she and Derek were running late by the time they got out the door, there had been no opportunity to stop for coffee. She was desperate enough, in fact, to check the nurses station to see if there was anything left in the coffee machine, but before she could get there Addison found herself being grabbed by the arm and yanked into an empty storage closet.
"What the--" she burst out, startled, but then she felt Derek's hands around her waist and his mouth against hers and she barely had time to lock the door before she found herself pressed up against the wall, locked in a passionate embrace with her husband. Twenty minutes later Addison had a ripped blouse and a hickey on her collarbone, while Derek had scratch marks across his back and a self-satisfied smirk on his face.
"Feel like giving up?" he grinned. "I know this is a hard act to follow."
Addison shook her head as she zipped up her skirt and adjusted her lab coat, trying to look like she hadn't spent the last twenty minutes having near-animal sex in the supply closet with her husband. "Just you wait. The day is still young."
She kissed her husband and let herself out into the thankfully deserted hallway. Suddenly she wasn't so tired anymore.
Derek had just sat down to lunch when he heard his pager go off. Damn. He was starving, and the cafeteria's food actually looked edible today. He glanced at his pager--911, Room 531. Derek sighed and dumped his soup in the trash before sprinting toward the elevator.
531's door was shut and the shades drawn, which would have seemed unusual if Derek had taken a moment to think about it. As it was, he was running on adrenaline and burst into the room to find his wife lying back on the bed, her beautiful red hair tumbling down her shoulders and a seductive smile on her face. She was wearing her favorite five hundred dollar high heels, her white lab coat, and…Derek swallowed. Damn, she was beautiful.
Addison beckoned him over and Derek stumbled over to the bed, unable to take his eyes off of his wife. "Just so you know," she whispered, her breath warm in his ear, "Bailey and her interns are coming to check on Mr. Henderson next door in ten minutes. And you're not one for being quiet during sex, Derek, so I suggest that you not waste any more time."
Nine and a half minutes later Derek was out the door, tugging on his scrub top as he sprinted around the corner just as he heard the familiar voices of Bailey and her interns behind him. He and Addison had had many close calls back in New York, and for a moment he felt like an intern again, stealing moments with his wife inbetween the many demands of their schedules.
Addison hadn't won yet, though. He still a few more surprises in store for her.
By the time six o'clock came around, Derek had had sex with his wife in an empty gallery (he had initiated that one), the showers in the attending locker room (Addison had surprised him there) and the elevator (he had come up with that location, obviously). He and Addison were both supposed to be off at seven, and Derek was plotting about how to take her out to dinner and sneak away with her during the meal when he was stopped by Burke, who wanted a neurological consult about a teenage patient of his.
Derek reluctantly shoved away his lustful thoughts of his wife and took his fellow attending to his office for some quiet. He sat down behind his desk and was just beginning to get the patient's case history from Burke when he felt a hand on his thigh.
No way. No ing way. Across the desk Burke continued to talk, unaware that Derek's wife was hiding beneath his desk and was doing some things that were making it just slightly difficult for Derek to concentrate on spinal malformations. He plastered a neutral expression on his face and tried his hardest to ignore what Addison was doing underneath his desk.
"Good God," he muttered suddenly, interrupting Burke's explanation of the particular surgical procedure he planned to use during the operation tomorrow. Damn. So much for ignoring Addison.
Burke furrowed his brow. "Excuse me?"
"I mean--" Derek began frantically. "Look, I'm sorry, it's been a long day and I'm wiped out. Can we talk about this tomorrow?"
"Of course," Burke agreed, but his expression clearly stated his disapproval of Derek's unprofessional attitude. "Clearly now isn't a good time for you."
Burke swept out of Derek's office, thankfully shutting the door behind him, and Addison crawled out from beneath the desk with an extremely self-satisfied expression on her face.
"You're Satan," Derek growled, pulling his wife onto his lap and kissing her hard. "That was the most evil thing anyone has ever done to me. Ever."
"But it was exciting, wasn't it?" Addison smirked.
"Fine. You win," Derek gave in, sliding his hands around her waist. "I'll do whatever you want."
Addison laughed and began to tug Derek's lab coat off of him. "I want you to say it."
He kissed her again, and stared into her beautiful green eyes. "Addison Forbes Montgomery-Shepherd…you are the best."
That night, the sex was anything but boring.
