(Christmas Day and Night 2007)

"Wake up Smerek, Wake up. It's Christmas."

Marti woke Derek up at 5 am, it had been the same thing ever since she could get out of her crib and talk, and this year was no different.

"Okay Smarti, Okay. I'm up. Let me get dressed at least before we go downstairs."

Once Derek was in his robe Marti proceeded to pull his hand until he was following her down the stairs and sitting next to her by the tree. Soon after she was seated Derek covered his ears in anticipation of Marti's wake up ritual.

"WAKE UP OR I'M GOING TO OPEN UP YOUR PREASENTS FOR YOU!"

No sooner had she screamed this Edwin, Lizzie, Nora, and George all hurried into the living room. Only Casey didn't come down the stairs. Instead she came out of the kitchen holding a tray full of food and walked straight over to Derek.

"Merry Christmas Derek," She said.

As she leaned over to put it on his lap he whispered in her ear only for her to hear,

"Remind me to thank the cook later."

"You better do more than just thank her," Casey replied.

It was like that throughout the day, Casey insisted Derek opened his present first and was served diner first even. Edwin along with everyone else in the family was shocked at Casey's display but she merely said that it was in the contract, which would then make Edwin say,

"Darn Derek, and we thought she had learned her place."

This would always earn him a slap to the back of the head by Casey followed by Derek whispering,

"Even on Christmas that miracle will never happen."

That night was just as eventful. Derek and Casey went to Sam's yearly Christmas party, again telling their parents they were going with certain people as a date, and arrived just when it was getting into full swing. Each grabbing their respective cups of beer they proceeded to make their rounds around the house. It was kind of routine now for them during parties to stop by the Hockey team, for Derek to show Casey off, over to the kitchen where some of Casey's old school friends were, and of course Sam's room to break Sam and Katie apart long enough to say hi and catch up.

Casey normally nursed one beer the entire night but she felt that she needed more courage for something she had planned for later. Derek was a different story however when it came to alcohol. If he saw it, he drank it. Casey tried to limit him tonight and was successful for the most part, he was only able to down 7 out of his normal 20 cups, so she took him down to B.I.C. (Burgers and Ice Cream) to clear his head before she took him home.

When they got there, thankfully, everyone was asleep so she was able to get him up the stairs and into his room with the door closed and locked firmly behind her. Derek noticed a box on his side table and was about to question it when his shirt was pulled over his head and thrown on the floor along with his shoes, socks, and pants. Casey pushed him back onto the bed and then removed her own clothing not leaving a single thing on. He was now trying to pull off his boxers she stopped him in mid tug.

"Now Case, thas not fair." He said slurring his words.

"I need you coherent when I ask you this Derek, it's about us and our future."

This made Derek sit up straight in his bed. A worried look crossed his face as he started to sober up quickly.

"What about us?"

"Derek, where do you see us in 5 years? Even in one year?" She asked.

Relaxing a little Derek was able to pull Casey down onto the bed next to him.

"Casey, in one year I see us sitting like this but at collage, we'll have our own dorm room and we'll have told Nora and George about us by then and they'll have accepted. Now, in five years I see us also like this but married, in our own house, you working towards your teaching degree and me starting as the new owner of B.I.C.s."

This threw Casey off. "Owner?" She questioned.

"Yeah, Bill offered me the job for when I graduate High school."

"Derek that's wonderful," Casey said while giving him a hug, "and were you serious about the marriage thing?"

"If I had a ring right now I would propose, you know I would."

"Well that brings me to my main question Derek. Last night wasn't your present, instead that little box right there is."

Casey got on one knee and grabbed the box.

"Derek Michael Venturi, we have been together for only a year but it seems like a life time. I know that it's normally the guy that proposes but I think that this will be something funny to tell our kids when we have them. Will you marry me?"

She then pulled out a single banned ring that had the carvings DV 3 CM. Before she had the chance to stand up on her own Derek pulled her up on top of him and kissed her full out.

"Damn, I wished I had asked you first." Derek said.

"So is that a yes?" Cassie asked.

"Yes, I love you Casey McDonald and I want to be with you for the rest of our lives. So let's ahh…Consummate our new beginning."

Casey could just giggle at his terminology.

Derek kissed her passionately on the lips and started to trail kisses down her neck. He stopped at her collarbone and was graced with a small moan of displeasure.

"Please don't stop."

Derek smirked at her request. He licked and sucked on her collarbone and then trailed more kisses down to her breast. He started on the right kissing the nipple and then took it into his mouth where he soon swirled his tongue around it. Hearing Casey's sighs and moans sent fire to his groin but he continued with his ministrations and soon gave the same amount of affection to her left one.

After her breast were thoroughly appreciated, Derek moved down her stomach and was soon just above her well-trimmed patch. Instead of continuing he went straight past them to her knees and then started to kiss his way up to her mound. Once there he continuously flicked his tongue over her clit and soon had her climaxing while he drank her juices. After that she seemed to purr like a cat that had just caught the canary.

"Now it your turn Derek." She said with a smile on her lips.

Following Derek's previous example, she started at his lips and went down. She did not however stop at his nipples, since he was ticklish there, but continued down to his shaft where she kissed along the underside and then licked where she had just kissed. Casey did this with all four sides of Derek's cock and soon she was licking him like an ice cream cone. She lightly grabbed his sac and started to knead them when she took him fully in her mouth and Derek let out a groan. After a few minutes he pulled her off of him and brought her lips up to his.

Their mouths, tongues, and bodies were fighting for dominance. At one point Derek would be on top but the next Casey would. They wanted to bring the other pleasure but at the same time reach their own climax. Within 20 minutes of starting Casey had climaxed 3 more times and Derek was soon on his way too. It was another half hour before he finally pulled her on top of him finally spent. Kissing her forehead, he fell into a peaceful sleep as did she for each knew their relationship would only strengthen with time.
