Title: Warm, Tingling, Sweet and Pounding

Ship: Lucifer & Trixie; Deckerstar

Genre: Angsty/Fluffish/

A/N: I do recommend listening to "Perfect" by Ed Sheeran while reading, I listened to it on repeat while writing. English is not my first language, and despite my certain level of fluency, I still have a lot to learn and I commit a lot of mistakes, so feel free to point any mistake you find! I love to learn even more.

Description: When Lucifer is the only one free to babysit Trixie, the Devil receives much more than he bargained for.

Or

How a human child taught the Devil more about life than he ever expected.

Chapter One: Faith

His elegant hands traveled through the keys as he started to play the melody and his voice accompanied right after.

I found a love for me

Darling, just dive right in

and follow my lead

Well, I found a girl, beautiful and sweet

Oh, I never knew you were

The someone waiting for me (…)

Images played into his mind while the lyrics rolled from his mouth, earning, full of emotion. It was those small moments all pretenses fell to the ground and his voice spoke volumes.

(…) I will not give you up this time

But darling, just kiss me slow

Your heart is all I own

And in your eyes you're holding mine (…)

The memory of her lips still lingered on his own, bringing a faint smile. It was still so sweet and gentle, so uncharacteristically to him. After all, he was used to lustful and hungry kisses, but not that sweet lingering one. She was the only one that has ever given him one like that.

(…) Well I found a woman, stronger

Than anyone I know

She shares my dreams

I hope that someday I'll share her home

I found a love, to carry

More than just my secrets (…)

Chole Decker was special, the strongest he had ever encountered in his long existence. He admired everything about her, her strong character and her infallible sense of justice. She was intelligent, witty, humorous, down to earth, amazingly good. His miracle indeed.

(…) But we're so in love

Fighting against all odds

I know we'll be alright this time

Darling, just hold my hand

Be my girl, I'll be your man

I see my future in your eyes (…)

Sometimes he could even grasp a small piece of the future when he looked deep into those blue-grey eyes. But it always ends up squashed, then, at the memory of what his Father had done, and what his Mother did. He could still feel the cracks in his heart, still painful as in the day he had received them.

Would he ever have what he desired? It sounded so ironic for someone that brought people's deepest desires couldn't have what they wanted most. He guessed it was the twisted way his Father had to keep punishing him.

(…) Baby, I'm dancing in the dark

With you between my arms

Barefoot on the grass

Listening to our favorite song

I have faith in what I see (…)

As he entered the last verse memories of when they danced alone at LUX while he made an impromptu prom for Chole, came dancing into the front of his mind. He could still feel her body against his, her figure in between his arms, their hearts beating in perfect synchrony. It brought so many emotions he was trying so much to keep to himself. Because it wasn't fair. It never was.

(…) Now I know I have met an angel in person

And she looks perfect, I don't deserve this

You look perfect tonight

He pressed the last key, still lost in all those emotions that were pouring out of his heart through borrowed lyrics when the cheery voice of Trixie interrupted his moment.

"Are you in love Lucifer?" She blinked her big brown eyes with an innocent touch.

"What makes you think that, spawn?" He diverted the question with another, grabbing his drink while raising from the piano bench.

Trixie grabbed her children-friendly drink – the one that Chole insisted Lucifer buy when he ended up being the only one able to babysit the little human when all the common options run out – and followed him. Chloe and Maze were out, a tribe's night – an attempt of Ella to help Maze and Linda's friendship – and Dan was stuck at work in the eleventh hour when Pierce dropped a huge workload over the detective in the last minute. It was late to call a babysitter, and, in the end, he was left with that work.

The things he did for the Detective. He shook his head in half-amusement-half-helplessness. At least he convinced the woman to let the spawn sleep at his penthouse, after a long battle of arguments and his promise he would lock-down his private lift with a pin – what he did. With a bodyguard to boot. He needed to work on his night work too, after all.

"Well… For starters, you chose this song" she said as it was an obvious thing, and Lucifer was tempted to remember her she asked for him to sing her a song from the last decade, and Ed Sheeran was a very interesting and talented guy, he actually enjoyed the lad "and when you were singing you had that… Humm…" Trixie frowned as she tried to find the best explanation. "Pained expression people do when they are suffering from love, or when they really want to go to the bathroom." She finished with a shrug.

Lucifer stared at the child with a blank look. "I wonder where you take these ideas." He frowned. Maybe he should talk to the Detective about those strange things her daughter seems to love to utter nowadays.

"You still haven't answered my question, Lucifer." She shot him a look that was so much her mother, the Devil thought he was looking to Chole.

"I can call upon my right of not speaking, little human" he sipped his drink in the more dismissive and intimidating way he could muster.

Trixie smiled and copied him and his way of drinking with her own beverage. She turned to look at him again, her dark eyes boring into his with a serious gaze, almost business-like.

"That's true, but your silence just answers my question" the child smiles triumphantly.

Lucifer frowned even more. "It doesn't answer anything." It came out more as whine than an actual adult response.

She giggles as if she was the holder of the greater secret of all world and shot Lucifer a knowing glance, what made the former Lord of Hell buff in irritation.

"What this is supposed to mean, spawn?"

"This what?"

"This look! What's supposed to mean?" He lost his temper, what made Trixie giggle more, her eyes twinkling with mischief.

"That I know you are in love and you are trying to deny it!"

Lucifer averted his eyes with a snort. How can a child read him so easily? He wondered if Chloe was as perceptive or she chose to ignore for her own good. Humans were especially good at it. Not more than him, of course.

Trixie tilted her head sideways to look at him contemplatively for a short while, her giggle being replaced by a soft smile and fondness replacing the prior mischief in her eyes. With a soft voice, she started speaking again.

"It's okay to love, Lucifer."

"What do you even know about love?" He questioned, exasperated.

"Everything!" She extended her arms to each side of her to show how much she knew. "It is that warm feeling I have every time mommy kiss me, and when daddy gives me his hugs. It is that tingling at the bottom of my belly when Maze teach me the fighting techniques and watches movies with me, it is that sweet taste in my mouth when you pat my head. It is the pounding on my chest when Ella tell me all her stories, or when Linda smiles and talks to me, or even when Amenadiel smiles at me. This is all love." She speaks fast and excited, but Lucifer can hear every single word.

He clears his throat. "It seems you have too much love to give." He wouldn't admit he was impressed with her speech. Not now anyway. So he gave the statement that was the truest of all. No compromises.

She smiles in answer and nods. "Love is given freely and is wonderful. You shouldn't be afraid of it…" Trixie furrowed and abandoned her cup on his coffee table and sits close to him, who frets a little bit and stiffens. "Why are you afraid Lucifer? Did they hurt you?"

Her gentle tone and concern puzzled the Devil, but also made his heart flutter. How can that small human gives it so effortlessly and make it sound so easy? It was never like that. If it was, he couldn't remember anymore. He forgot how to freely love if he had ever loved as the little girl was describing it. Which he doubted.

"Quite the contrary, I was the one hurting her" he laughs bitterly "it wasn't my intention… Not completely. All I did was for her." He hummed as he gave another sip of his Scotch. It was the truth, or so he told himself every single day. "No, it wasn't her. That has only one person that could have ever spoiled anything for me… My dear Ol' Dad." Since the beginning.

"Why would he do that?" Trixie frowned.

He looked at her with what could have been called a fond smile.

"You wouldn't understand… But let's say my Dad has a penchant for control. Mostly... His children." He shrugged. "Especially me"

Trixie moved closer and before Lucifer could react she cupped his face with both of her small hands, looking at his eyes intently. He flinched at her touch, but she was strong and held on.

"Your Dad is mean… But, don't let it get in your way."

"It's not that easy, Beatrice." He took her hands off his face.

"Why not? You love her, don't you? You desire her, don't you? You told me I should aim for everything I want, to get what I desire most. Why won't you follow your own words?" She asked without spearing a single breath.

"Whoa, whoa, calm down spawn…" Lucifer was worried she would die of oxygen deprivation. "It's complicated."

"It's not"

"It is"

"It's not"

"It is"

"It's not"

"It is"

"It's not"

"It is"

"It's not"

"It is"

"It's not multiplied by billions!"

"It is multiplied by eons and I won! Boohoo!"

A very frustrated Trixie crossed her arms with a big pout on her lips, while a grinning Lucifer drank the rest of the content of his cup. She buffed and turned to look at him with all her righteous angriness of a child.

"I don't understand you, grown-ups, and all this 'complicated' stuff… It is usually an excuse." She said with a big frown and grabbed her own cup and finished her children drink. "Your lot complicate it all by putting unnecessary obstacles to something so simple. Love is love." She said with finality as if the whole truth of the universe was in that. And maybe it was.

Lucifer didn't answer her, opting to grab his and hers cups to fill with more drinks. He surely needed another one, not that it would make any difference. He filled his with Scotch and hers with something called Ginger Beer and brought back to her.

"Maybe you think is so simple now, spawn, because you still haven't actually felt how the world works, nothing is so simple anymore." He sits down again, this time in a single chair. "I don't know where you took all these ideas you have from, they sound so wistful, but I know for certain that what I had with Ch… With her, that can't be. She didn't have a choice. And not being with her gives that back to her." He hoped she hasn't noticed his almost slip.

Trixie was quiet all the while he spoke, biting her bottom lip and munching it, her eyes never faltering. She was doing everything to hold her smile.

"I don't even know why I'm speaking with a child about all of this, it just doesn't make sense. What you could possibly know that I don't, Beatrice?" He shook his head while he spoke. "I have eons of existence, I think I have the big picture here."

"Faith" She interrupted him, cutting his momentum. He gaped at her.

He scoffed and drank more of his Scotch. "Faith? Ha!"

"Not that kind of faith…" She shakes her head and hands as to emphasize her point. "Faith in her… In the both of you."

"How can I, if all wasn't real!?" He let it out with such anguish in his voice. "It broke me into pieces, I can't let it happen to her." He closed his eyes and breathed deeply.

At that moment, Trixie decided that maybe she had crossed a line. But she still didn't understand why Lucifer was making this so difficult for himself, how adults, in general, liked to complicate life. It was so simple. Love is supposed to be simple. It was all the warm, tingling, sweet and pounding feeling she was surrounded by. She got up and with a swift move, she propped herself on his lap, receiving a grunt and a squirm as a reflex when she hugged him tightly.

"I'm sorry Lucifer, for upsetting you." She said sincerely, her voice dripping with her regret. She felt her heart hurt, for him and for… "Her".

"That's okay, spawn…" He tapped her head in hopes of making her release him. But Trixie being Trixie didn't let him go, eliciting a sigh in the Devil.

But he never expected the words coming from the little human at that moment. It warmed his heart despite all.

"I will have faith in the both of you, for you."

He smiled and placed his hand on her back, gently tapping it, albeit awkwardly.

"Thank you"

A/N: Hello, hello… This is my first time writing a story in this fandom, and I hope you like it. I've been wanting to write a story of Lucifer for a while, however, I quite didn't know what I wanted to write… I always felt like my plots weren't good enough.

To be honest, I don't even know what I want with this one here either. Despite it was easier to write because I decided to go to a more light and sweet aspect. It ended up a little bit more angsty than I expected, but well… It will have fluff, a lot of it. And romance, sorta, more towards the end. I'm not quite sure yet.

In the max, this story will have 3 chapters, I hope. If not, it will be just this one. Still deciding. I will post when I have all of it written, however, I decided to post this just to see how it will be received. Well… Thoughts?
