Title: The Unexpected Gift

Summary: Natsu and Jun prepared surprise gifts for Lucy's birthday. What did the father and son duo have in store for her?

A/N: For those not familiar with it, the song is from Phineas & Ferb.

The soft morning light filtered through her still sleepy eyes and made her stir in bed. Her arm automatically reaches out to look for her personal human heater, only to find the space beside her empty. Her eyes slowly opened. Indeed, she is alone. Her husband is nowhere to be seen.

She pushed the blanket away and sat up on their bed. She rubbed her eyes and softly yawned, stretching her arms behind her head.

"Natsu?" she called, sure that her husband would hear her from anywhere in their house.

She heard footsteps and his voice from outside their room. What's happening out there?

"Ah crap! Your mom is awake!" Natsu smacked his forehead. "You ready, Jun?"

His 5 year old son saluted at him. "Aye sir!"

Natsu laughed, amused at his son's manner of speech. "You sound like Happy, kid."

He heard the door open and saw Lucy, still in bed clothes, standing there. "What's happening here?" She asked amusedly. She crossed her arms as she waited for the answer.

Natsu looked down at Jun. "Let's do this!" Both father and son put their hands on their hips and breathed deeply.

"Bow, chicka, bow-wow." Natsu and Jun started, as their feet tapped in unison.

"That's what my baby said." Natsu pointed two fingers at Jun.

"Mow, mow, mow." Jun sang, jumping in place.

Father and son placed their hands on their chests, "And my heart starts pumpin'." Natsu winked at Lucy suggestively.

"Chicka, chicka, choo woop." Both of them were jumping now.

They held out one hand and shook their heads, "Never gonna stop."

"Gitchi gitchi goo means that I love you!"

Lucy laughed as she watched them dance and sing. Tears started pooled around her eyes from so much laughter as Natsu and Jun finished the song. They were singing a song from Jun's favorite cartoon show. When did they practice this?

"Gitchi gitchi goo means that I love you Baby! Baby! Baby!" Natsu and Jun belted out, their son almost shouting the lyrics. "Gitchi gitchi goo means that I LOVE YOU!" They ended their performance with an exaggerated bow, Jun almost tripped on his feet.

Lucy clapped, still laughing amusedly at her family. "Bravo!" She opened her arms, inviting them for a group hug. Natsu picked up their son and they all shared a tight embrace.

"Happy birthday, Lucy!" Natsu greeted, grinning widely at her.

"Happy birthday, Mama!" Jun hugged her neck and planted a kiss on her cheek.

Lucy smiled at their gesture. "Thank you, both of you!" She pecked on Natsu's lips while she gave Jun a forehead kiss. She knew her words were not enough to express how touched she is with their gesture. "Gitchi gitchi goo you too." she said lovingly.

Natsu put down Jun and patted his back. "Go get your gift for Mama." He quickly disappeared to his room, closing his door carefully.

Lucy looked at Natsu questioningly, "There's still more?"

Natsu nodded excitedly. "He made it last night."

The door creaked as Jun got out of his room, clutching a piece of paper in his hand. He ran to his mother, waving the paper at her. "For you, Mama!"

"Thank you." Lucy picked it up. It was a hand-made card. She opened it and saw Jun's drawing. There was Natsu with his spiky pink hair and white scarf, Lucy with long yellow hair, and a two little people. She was sure that Jun was the boy with the pink hair. Jun's drawing of himself held a little girl with yellow pigtails.

"Jun, who is this little girl?" she asked her son, pointing to the drawing.

Jun smiled widely. "Baby sister! Jun is taking care of her."

Lucy was astounded. He wants a baby sister now? "You want a baby sister?"

Jun nodded. "Jun will be big brother and she will be baby sister! Then we'll share toys and sing together."

She was speechless. She looked at Natsu, who was trying so hard to keep himself from laughing. His cheeks were puffed up while his hand was over his mouth. "You told him this didn't you?" she asked, amusement coloring her words.

Natsu shook his head. "No, he made it himself. All of it was his idea."

"I don't think he can write 'Happy Birthday' by himself, Natsu." Lucy stated, not really believing her husband. She knew his handwriting at first glance.

He raised his hands in surrender. "Okay, you got me there. Jun asked me to write that part but he drew everything else. Also, the dance was his idea."

Lucy looked at their son fondly and scooped him up into her arms. "But what about baby brother huh?" she asked him.

Jun touched a finger to his head, thinking about Lucy's question. "Is okay." He nodded. "Jun will take care of him too."

Natsu burst out laughing, wiping tears on his eyes. He was shaking his head as he went back inside their room. A few moments after, he was standing by the door, holding out a pink paper bag.

"I guess my gift will be put to use very soon." He grinned at her suggestively.

Lucy put down Jun and seated him on the couch. His toy box was there so he immediately played with them. She kissed him again and stood up. She walked to Natsu, curious as to what his gift for her is.

She accepted the paper bag from Natsu and suspiciously looked inside. She gingerly reached inside and felt something soft inside. Even without seeing what's inside, she was sure it was silk and lace.

"Think we start on working on Jun's request later tonight?" He asked, a wicked smirk plastered on his face.

She touched Natsu's cheek and leaned close. "Which one? Baby sister or baby brother?" she whispered back, enjoying their talk more than she was supposed to.

Natsu slowly wrapped an arm around her waist and pulled her close. "Guess we'll see after 9 months."

A/N: Isn't Jun-chan the cutest? This is currently my favorite piece for my NaLu week presentations! I'm still working on Day 4-7 and another bonus prompt. I'll try my best to finish them all. Thank you for reading!
