A/N : If I'm ever going to furthur into medical studies, I'll be blaming Lisa (McDreamy) for making me think of squee each time I open my textbook.
"That looks like a textbook," Derek commented, confused, as he entered the trailer to find his wife sitting on the couch perusing a book in her lap.
"It is," Addison answered without ever looking up from the text.
He leaned across the couch and glanced over her shoulder, "You do know you've already passed Med School, right?"
Addison rolled her eyes and turned her head to look at him, "My certification is ready to expire. I have to take the exam tomorrow. Yours is due to expire, too, isn't it?"
"Yeah, but you wouldn't catch me looking over a textbook," He pressed his lips to her neck as he sat on the edge of the couch with her, "I was actually thinking we could study the way we used to. You know, like in Med School?"
She shrugged her shoulders to push him away; "You don't think we're a little bit mature for that?"
"You're the one pouring over a text book," Derek grinned as he brought his lips to her neck again, not to be deterred.
"Fine," Addison slammed the book shut and dropped it on the floor next to the couch.
Derek grinned and he offered his hands to help Addison to her feet, "Let's go."
Addison followed him to the bedroom and leaned against the doorjamb to the bedroom as she watched Derek lean back atop the covers, watching her.
"Do I need to remind you how this works?" Derek wondered, motioning for her to join him on the bed.
"Oh, no, I think I remember," Addison gave him a coy grin as she moved to get on the bed, "Shirt off."
Derek unbuttoned his shirt as quickly as he could manage before discarding it on the floor. She crawled slowly to him and placed her hands on his chest, pushing him back against the pillows. She put one leg on each side of Derek and was effectively straddling him.
Addison put her weight back on Derek's hips, eliciting a low groan from him, and ran her hands along his chest, "Now, let's see. These would be the pectoral muscles."
"Yep," Derek nodded, shivering in anticipation at whatever she would do next.
"The mandible," She placed a tender kiss at his jaw, and she nipped his upper lip with her teeth, "The labium."
Derek closed his eyes as she licked his lips with her tongue and mumbled the anatomical term. After minutes of teasing his mouth, she moved to his ear and nipped that, spouting the medical terminology for everything she could remember.
"Is it my turn?" Derek's breathing was heavy; Addison's teasing was almost too much for him. He wanted his chance to drive her crazy.
Addison rolled her hips back as she sat up, creating friction between their hips, "I'm not done with you yet."
She trailed her fingers along his abdomen and to the button on his khakis and deftly undid them. He raised his hips, allowing her to slide them down his legs. With a coy grin, she pressed her lips to his big toe.
"Phalange," She whispered and the pressed a kiss to his knee, "Patella."
Derek gasped as her fingernails made their way past her lips, traveling along the 'quadricep' and 'hamstring.' They stopped just shy of his groin, and his hands instinctively reached out to pull hers to his desired destination.
"Stop it. You'll have your turn," She slapped his hand away.
"Ooh, feisty," Derek teased as he felt her hot breath trail up his abdomen.
She took his lips in a kiss teeming with desire before allowing him to flip her over, so she was underneath.
"Now let's see," He pulled his old Columbia T-shirt over her head and observed her body momentarily before pressing a soft kiss to each of her cheeks, murmuring, "Malar."
Addison lifted her lips to his instinctively, expecting a kiss.
"No," Derek shook his head and placed a finger to her lips, "My turn."
"You're evil," Addison moaned as he dragged his lips down her neck.
"The larynx," He ignored her complaints.
Derek had never been one for the slow temptation and lasted only a few more minutes before going for the kill. His hands slipped lower and lower, but he never quit whispering the anatomical terms in her ears. When he finally made it to his destination, his words were drowned out by her moans as he pushed her over the edge.
As she came down from her high, Addison brought his lips to hers. She was done with the games and let him know by reaching to remove his boxers.
Derek's breath was still coming in heavy spurts as he kissed the side of Addison's head and wondered, "So, you still think we're too mature to study like that?"
Addison chuckled, "Actually, I was thinking we were a little rusty and out of practice. We don't do it often enough."
"Hmm, we can't have two doctors who are out of practice," Derek grinned, stretching over to kiss her lips.
"That would be a travesty," Addison agreed and rolled on top of him, laughing softly.
