A/N : Now this is call taking advantage of Derek. :D By Raven (Paroducks)!
When they arrived at the party Derek kissed Addison on the cheek before heading over to talk to Weiss. The Shepherds were in New York for his little sister's wedding. This was the Bachelor/Bachelorette party. The liquor flowed freely and in a few hours everyone was pretty knackered except Addison. Addison sat on the floor talking with Sav, sipping a Pepsi. She laughed at Sav's story, attracting Derek's attention from across the room. Derek has a small smile on his face as he watched Addison happy and laughing. Addison must have felt him looking at her because she met his gaze and winked at him before smiling.
Addison watched as a drunken Derek ambled over to drop a kiss on her head as he went to refill his Scotch. A brilliant smile crossed Addison's face at that small act of affection before she turned back to her conversation with Sav.
A few hours later, Addison escorted a drunken Derek to their hotel room. When she came out of the bathroom, she found Derek dozing in bed. Addison climbed in bed and snuggled down next to him, before starting to plant kisses on his neck. Derek cracked open one eye "What are you doing"
Addison smirked up at him as her hand slid down his bare abs "Nothing. Go back to sleep while I have my way with you."
Derek responded by grabbing Addison by her arms and yanking her on top off him. Derek leaned back folding his arms behind his head and leered at Addison's barely there lingerie. "Now you can go ahead."
Addison leaned over him to kiss his chest and moved her way down. Derek groaned in response to his wife's advances.
Addison whispered in his ear, "Shh. You're supposed to be sleeping," she then slid down his body until she was sitting on his thighs. She then started easing Derek's pajama bottoms down. She smirked when she how happy Derek was to see her. She dropped a kiss on it before impaling herself on him. Derek ran his hands over Addison's curves, as she started moving on him. It wasn't long before they both went over the edge calling each other's name.
When Addison started to move off Derek, he stilled her movements by he wrapped his arms around her and sleepily whispered, "Stay," as he kissed her head. Addison responded by nodding and resting her head on Derek's shoulder. It wasn't long before both Addison and Derek fell asleep with smiles on their faces.
