AN: Set during 'Raindrops falling on your head' after Addison leaved Derek in the lobby and the next morning.

-------

A half asleep and drunk Addison cracked open her hotel suite's door after peaking to see who was knocking on her door at 1am.

"Derek?" Addison started to question before a yawn interrupted, "What are you doing here? How did you find me?" she stepped back to let her husband in.

"Richard," Derek replied as he dropped his bag near the door, "I couldn't sleep."

"I was wondering where that went," Derek smirked as took in his wife's pajamas. She was wearing his old college soccer jersey and a pair of panties.

Addison blushed as Derek leered at her.

He saw a pillow, a blanket on the couch with a half empty bottle of wine on the table in front of it before he mocked his wife, "Still can't sleep in a bed without me, huh?"

"Like you can?" Addison mocked back as she followed her husband's trail of dropped clothing.

She smiled faintly as she watched a drunk Derek climb into the bed, "You're drunk, Derek."

"So? You're an adulteress bitch," Derek said as he patted the bed next to him, "This doesn't change anything. I'm still mad at you."

"As is your right," Addison said as she crawled into the bed, "I'm an adulteress bitch. Got it."

Derek was fighting the Sandman's call as he asked, "How did you manage to get any sleep when I left?"

It took a moment for the question to be comprehended by a sleepy Addison.

"Sleeping pills. Alcohol. Both," Addison whispered as snuggled into her husband's side, "You?"

"Same," Derek whispered as his eyes drifted shut, "I missed you, babe."

Derek became aware of several things as he slowly regained consciousness. He had his arms around a woman and he knew this because his hand was cupping her breast while his other hand was stroking the skin just under the edge of her panties. He smelled the hair his nose was buried in. He smiled as he sleepily recognized the scent. His hand slipped further south as he pressed himself against her backside.

Addison roused as phone continued to ring annoyingly. The phone stopped ring as she sleepily reached for it. Her eyes snapped open as she realized that her naked breasts were brushing against a bare, muscular chest. She gasped softly as she saw that she was lying on top of Derek. She wriggled to find out just how intimate she had been with her husband causing her eyes to widen further.

"Quit moving, Addie," Derek mumbled as his arm tightened around her waist.

She pressed a kiss to Derek's neck before sitting up only to be stopped as her husband grabbed her hips and flipped them over. Addison's eyes drifted shut in pleasure as Derek started to move against her. Hands roamed freely as the furious pace increased. Pretty soon the only thing heard in the room were moaning and gasping before it all came to a volatile conclusion.

-

Afterwards, Addison held the sheet to her chest as she watched Derek get dressed.

Derek had made it all the way to the door before he stopped and rested his head against the door. He dropped his bag before turning to walk back towards his wife. His gazed raked over her, taking in her tousled hair before settling on her kiss swollen lips.

"This doesn't change anything," Derek said before pressing a hard open mouth kiss to his wife's lips. Their tongues tangled passionately before Derek pulled away and walked out the door.
