"Chloe we're not even sure if he's gonna be there, I mean you've checked three times last week I-"
Ella Lopez was desperately trying to keep her favourite detective from hurting herself again, but she was too headstrong.
"I know Ella, but this time I'll see him playing the piano or having sex with random girls and boys!", she replied while leaving the police station with something new in her bright eyes: hope.
Lucifer had been gone for five months but his first love hadn't given up a single second on bringing him back in Los Angeles. Chloe Decker routine became simply like this: solving problems, playing with Trixie and then visiting Lux hoping to see him there. And she's never stopped. In five long months.
This time she was feeling something inside her chest, maybe a beat or tickling; anyway shit was gonna happen.
All her doubts were clarified as soon as she entered the night club, feeling a pungent but sweet scent at the same time, drawing her towards the penthouse of the building. She took the elevator with her heart in her mouth, excited, and at that moment, when the doors opened, she saw him. 
As handsome as the hell he was king of, tall and muscular, sad.  His sly eyes were full of tears and remorse, but as soon as they alighted on those of Chloe they began to glow like eternal flames.
"Lucifer.." she whispered before running towards the tall man to hug him very tightly.
"Detective I'm... sorry.", he replied confused by the big and warm hug. Lucifer thought that he didn't deserve that hug at all for leaving Chloe alone, but when he looked at her every sense of guilt vanished.
Chloe looked up as she lost herself in his eyes, and said: "shh don't say anything please", and saying that without a second thought she kissed him.  A beautiful kiss, long and sweet. Both dropped their defense systems, their own bodies, until they remained a single soul in two hearts. 
The kiss was followed by another hundred, perhaps a thousand, until they found themselves lying in bed to complement each other. "Detective, are you sure you want to do this?" He asked thoughtfully above her, sweating and happy. 
Chloe smiled kissing his chest, letting go with a cheerful: "fuck it!".
So Lucifer joined her, thrusting gently into her breathtaking body, enjoying every fucking second with his first love.  Their moans filled the room with the sunset over the city, while in that lusty penthouse something more beautiful than paradise was being created. After coitus, the devil and his angel enjoyed playing their piano song in whiskey-flavored kisses. 
They were meant to be together just like a bullet and a gun, or maybe like heart and soul.
