I know Lincoln loves all of his sisters, but I especially love the connection between him and Luna. So I thought I could write a bonding fanfic for this one. P.S the song as you read is inspired by the "Phineas and Ferb" song, Little brother.

Disclaimer: I don't own the Loud house

10:30pm at the Loud house, and everyone was asleep. Unfortunately, the same can't be said for Luna. She tossed and turned in her bed. Not even Listening to music on her headphones helped. Luna gave up and looked down into her roommate' s empty bottom bunk. She sadly sighed and muttered, "With Luan at a friend's sleepover, it gets a little lonesome in here." Luna then had an idea, "Maybe until Lincoln wouldn't mind I bunk with him until then."

She carefully opened her door and came out of her room. To her surprise, Luna heard the bathroom door open. She turned around to see…"Bro?"

A groggy Lincoln is revealed to be exiting the bathroom. He looks up and sees Luna in the hallway. "Luna, is that you?" He asked, trying to see clearly.

"Yeah, dude, it's me," Luna replied. "I ask, but it looks like you just needed the loo."

"Yeah, but what are you doing up this late?" Lincoln asked as he regained his vision.

"I couldn't catch any z's, and I think it's because Luan's away and all. I actually wanted to, if you're up for it of course, let me bunk with you until then?"

Lincoln smiled warmly at her, "Sure, Luna. I'd be more happy to."

Luna smiled back, and embraced him with a gentle hug to which he returned and gave her a kiss on the cheek, causing Luna to laugh. "Thanks, Linc. How about we go in my room?"

"Sounds good to me, Let's go."

After the hug, they went into the former and Luan's room. "Hey bro?"

"Yes, Luna?" Lincoln asked.

Luna hesitated, "One more thing, which ever bunk you want to sleep in…mind if I join you?"

Again like before, Lincoln smiled warmly at her. "Not at all. Let's sleep in Luan's bed."

Luna smiled, and double checked Luan's mattress to see if it's full of pranks. There seemed to be none, so Luna climbed in bed, followed by Lincoln. "Comfy?"

Lincoln nodded. "Just so you know, I get lonely in my own room too sometimes. That's why I let Charles sleep in my bed every now and then."

Luna was touched by her brother's own experience. "Well, now we don't have to be lonely. We got each other." The siblings shared another hug as Luna implanted several kisses on Lincoln's cheek to which he bursted into laughter.

"Hey…you know that tickles," Lincoln continued to be subdued into Luna's kissing ambush.

Eventually Luna ended it, allowing her brother to catch his breath. She gave him one final kiss, "Sorry, bro. Couldn't help myself," she said with a slight look of smirk. It soon turned into a warm smile. "I'm really glad you're spending the night with me."

"Me too," Lincoln agreed. Then heard a small bark. They're attention turned around to see their dog, Charles, beside them on the floor, with Lincoln's plushy Bun-Bun in his mouth. "Charles?" The dog climbed up on the bed to his owners.

"Charles, you sly dog," Luna commented with a smile.

Charles shows Bun-Bun to Lincoln. "Oh, you brought Bun-Bun with you." He takes the bunny out of Charles' mouth and smiles at him followed with a friendly pet on the head. "Thanks, boy." Charles then sat down with a set of puppy eyes. Lincoln quickly figured it out and turned to Luna. "What do you say, Luna. Can Charles sleep with us, cause it's alright with me."

"Why not," Luna agreed, "Now it's three of us bunkin' tonight." Charles perked up and affectionly kissed his owners with his tongue a few times. The siblings laughed at their dog's doing.

"Hey Luna?"

"What's up?"

"Would it be okay if you sang that song like you did when I was little?"

Luna smiled, "Huddle close, first." Lincoln complied, and snuggled close to his sister. Charles did the same. Luna took a deep breath and started singing…

Little brother, I remember you in my arms

We grew together

Little brother of my own

Even through all the chaos, you'll always be my little brother cause you're younger, and we're related, my little brother

So sweet and gentle, my love will always be with you

Little brother

Little brother

Little brother

Lincoln and Charles fell asleep by the time the song finished. Luna smiled warmly as she watched them sleep. She gently stroked her brother's hair with her fingers. Then she brought the sleeping Charles close into her and Lincoln's embrace. She whispered to Lincoln, "Sweet dreams, baby bro. I love you." Luna soon closed her eyes and drifted off to sleep. She no longer felt alone with her brother and dog by her side, dreaming the night away.

The End
