Just as she had promised, Lydia arrived at the house in twenty minutes along with the rest of the pack who were all holding balloons and a box. Stiles practically threw himself off of the sofa and ran out of the living room to answer the front door, causing Derek to raise an eyebrow and shake his head as he chuckled at how goofy his mate was.

Stiles hurried to open the door and he threw it open as the pack walked up the porch steps, unfazed at how energetic he was. "Lydia, you are brilliant!"

"I know" Lydia smiled as she flicked her strawberry blond hair off of her shoulder, before she handed him the box that she was holding.

"You reek of anxiety" Jackson stated as he walked past Stiles.

"I wonder why" Stiles rolled his eyes as Jackson groaned at his sarcasm. The spark then rushed back towards the living room and he poked his head around the door "I know that it's not Christmas day yet and that you might not have got me anything because you're a Sourwolf. But I've got you a present".

"Breathe" Derek reminded his boyfriend.

Stiles nodded before he walked into the living room with his hands behind his back, anxiety radiating off of him.

Derek put his book down and he sat up "What is it?".

Stiles walked over to the sofa and he handed Derek the box, he then stepped back a bit "You can come in now, guys!" He yelled as he turned his head.

The living room door opened again and Derek looked up just as Scott, Alison, Erica, Isaac, Peter, Deaton, Ethan, Boyd and Malia walked into the room closely followed by Lydia and Jackson with Kira. They were all holding baby pink and baby blue balloons and smiling like crazy people, Derek could hear all of their heartbeats and he knew that they were excited about something.

"What is all of this?" Derek asked.

"Just open the present!" Malia yelled.

Derek raised an eyebrow and he sighed as he started to unwrap the present, whilst everyone watched on in anticipation.

Stiles was nervously biting lip and he was fiddling with his hands anxiously 'Please be happy' he thought.

Derek put the wrapping paper down on the floor and he lifted the lid of the box before he placed it on the floor as well, he then looked into the box and he lifted one of the small onesies "My daddy is not grumpy with me?" The alpha read ad he held up the small cream onesie with rainbow writing on the front of it, he was puzzled for a moment but then he realised what all of the balloons meant and his head snapped up to look at Stiles "Are you serious?"

Stiles nodded as he pulled the positive pregnancy test out of his pocket "I found out a few days ago, I'm eight weeks pregnant".

Derek's face lit up and he put the onesie back into the box, he carefully put the box on the floor and he ran over to Stiles "Yes!" He cheered as he picked his mate up and hugged him.

Stiles smile beamed and he hugged Derek "I'm carrying our pup".

"I can't believe it!" Derek was grinning like an idiot as he hugged his mate, everyone else was smiling and cheering happily for the couple. Derek put Stiles down as a minute and he held onto his mate's hips as they kissed, Stiles wrapped his arms around the alpha's neck and he giggled happily as his mate kissed him.

"Can we have got coco now?" Isaac asked and everyone looked at him.

"Yeah, sit down and put a movie on" Derek nodded.

The pack happily situated themselves around the living room, before turning the tv on and flicking through Netflix, whilst Stiles and Derek walked out of the room and into the kitchen, where Derek pulled mate in for another big and kissed him again.

"You're incredible" The alpha stated, causing Stiles to smile happily.

"So you're happy about all of this?" The spark asked, still slightly anxious.

"Happy? Baby, you've made me the happiest and the luckiest man alive. I can't believe that we're going to have a baby and that I'm going to be a father" Derek answered as he stroked Stiles' cheek with his thumb.

Stiles' eyes instantly became teary and he sniffled as he smiled "You have no idea how happy that makes me".

Derek pulled stiles back into an embrace and he kissed his mate's head "I love you".

"I love you too" Stiles sniffled.

The couple embraced for a minute or so before they began to make hot cocos for the pack, Stiles put the sprinkles and whipped cream onto the drinks as finishing touches before he ate a chocolate flake. They both looked up and laughed when they heard that the pack we're bickering about which Christmas movie that they were going to watch.

"Go and put Home Alone on, I'll bring these in." Derek said with a gentle smile and Stiles nodded whilst smiling.

"Thank you" Stiles smiled up at Derek.

"No problem," the alpha said as he placed his hand on his mate's butt and he winked at the younger man, he quickly gave Stiles' butt a light pitch before he turned and walked out of the room, blushing furiously and biting his bottom lip.

"Stiles!" the pack called.

The spark Walked into the room and grabbed the remote, pressing play on what Christmas movie they were all going to watch. The pack all turned and waited for the movie to start as he sat down on the sofa, patiently waiting for his alpha to return.

Derek pushed the door open with his foot before he walked in with multiple hot cocos on a large tray, he placed them down on the coffee table in the corner of the room before he picked two up and walked over to Stiles "Here you go" he handed Stiles a mug.

Stiles looked at the drink and he smiled "Thank you".

"Merry Christmas, babe" Derek kissed his mate's head and then he sat down next to him.

Stiles turned his head and he looked at Derek, he kissed the alpha on the cheek and then he took a sip of his hot chocolate "Mmmmm" he closed his eyes as he hummed "This is so amazing".

"Just like you" Derek turned his head and he looked at Stiles.

Stiles blushed and he looked at Derek "And you" he mumbled.

Derek smiled and he wrapped his arm around his mate's shoulders and he kissed his cheek "I'm sorry that I upset you earlier, I'm sorry for being a Sourwolf towards you earlier. I hate fighting with you, I don't like it when you're upset".

Stiles could hear Derek's heart beating very fast and he could smell the tears pooling in his eyes, he quickly put the mug down on the coffee table and he snuggled up against the alpha "It's okay, don't get upset. Please don't feel upset". He whispered whilst he moved so that he was lying on his boyfriend's chest "What changed your mind about Christmas?" He asked as he felt two strong and proactive arms wrap around him.

"I remembered how much you loved Christmas and why decorating the tree is so special to you. I changed my opinion about Christmas because I know that you were very upset and I want to make our first Christmas living together very special for you. You deserve to always be happy" the alpha answered before he kissed his mate's head and Stiles looked up at him, Derek could not help but gaze in awe as his mate's eyes flashed a fiery orange and red.

"I love you so much. Thank you for all of this and for putting up with hyperactive me" Stiles said as he gazed up at his alpha.

"There is nothing to put up with" Derek stated as he moved his hand and started to stroke Stiles' hair "You're perfect just the way you are and I would not change you for the world. You're my beautiful mate and I love you so much".

Stiles smiled and he moved to kiss Derek "Merry Christmas, Der-bear" he whispered.

Derek smiled and he kissed Stiles back "Merry Christmas, my spark".

"Oh!" Deaton piped up and turned to look at Stiles "I forgot to tell you that there's a high chance of you having triplets because you're a Spark and a Luna, " he started before he turned back to the movie.

"What?!" everyone exclaimed as they started at Deaton and then at Stiles and Derek.

"Well... Looks like Derek won't the only one who had a surprise after all" Peter stated with a chuckle.
