This song was written to the Lana Del Rey song: Off to the Races. I recommend listening to it for this chapter but it's not necessary. I do not own anything DC or Lana Del Rey. Also be careful as this chapter contains strong sexual content. Enjoy my lovelies!

'My old man is a bad man, but I can't deny the way he holds my hand and he grabs me, he has me by my heart.'

They were driving over a 110mph but no-one stopped them. They raced through the highway across Gotham, their laughter maddening, loud and unstoppable.

Harley felt like this is where she should be, needed to be, by his side. Being the Queen of Gotham.
There was still a part of her, being buried further and further to the back of her mind, telling her this was crazy, insane and wrong. But she ignored that voice, embracing the crazy, savouring every delicious second she spent with the Joker, still covered in that man's blood but not caring.

"Where are we goin', Mister J?" Harley shouted above the roar of the engine as Joker turned off into an industrial estate that she had never seen before. What did he need to do down here?

Joker looked across at her, still grinning from ear to ear, leaning over and speaking quietly "Harley baby, I need to show you something. You need to know something about me." Before turning back to the road, delving deeper into the estate.

Harley's heart pounded in her chest, nervous, excited, maybe scared? She wasn't sure anymore but anything he wanted to show her was worth her time. They pulled up in front of a chemical plant, the largest in Gotham city. Harley could smell the acidic smell coming off the place before she even stepped out the car. She looked curiously at the Joker wondering what he had to show her here of all places.

As they got up to the gate he turned round to her "Harley, I think you are amazing. The way you have built yourself up from your past, your bad past, you have made something incredible from yourself, I want to show you something that I have never shown anyone before." His voice low and more personal than Harley had ever heard before.

'He doesn't mind I have a Las Vegas past, he doesn't mind I have a L.A crass way about me, he loves me with every beat of his cocaine heart.'

Harley was a goner, she had never had anyone say that to her before. The Joker, The Crown Prince of Crime wanted to share something with Harley he had never shared before. He loved her for her, and she was the damn luckiest woman in the world.

As he swiped a card key (god knows where had got it from), the door opened with a buzz letting them both in. He took her through a maze around the plant, not encountering a single soul. Harley couldn't help but wonder, shouldn't there be any security?

As if he could read her thoughts, Joker spoke quietly as they climbed a series of staircases "I made sure no one was here to invade our privacy."

Those words made Harley tingle in various places, her heart beat faster and she definitely felt herself blush, she realised that this was the most alone she had ever been with him.

As they climbed the last step, he took her out onto a walk way through another secure door. The walk way opened itself to the top of all the chemical vats, with steam pouring out of them. Why would he bring her here?

'Swimming pool, glimmering darling, white bikini off with my red nail polish.'

Joker turned round so he was facing her, walking backwards with his arms outstretched "This is where I come from Harley, this is where I became who I am." His exclamation echoed throughout the walls of the room, his voice loud and eyes bright with excitement.

Harley looked in horror into the bubbling, steaming vats, how was he even alive?

Joker continued as he saw the look of shock set in her face "It was Batman. I can't remember why I was here, or who I was but the last thing I saw before I went under was him. He made me fall in, which is why I need to show the world who he truly is! A crazy lunatic who dresses up like a rodent and tries to kill people!" Joker laughed manically at this, turning back round to face the chemicals below.

Harley looked at him under her eyelashes which were now dotted with tears. He had lost everything, anything he was before because of the Batman. Her previous views of right and wrong were now completely warped, here was her poor love whose life had been ruined by Gotham's apparent saviour.

Joker slowly walked up to Harley, grabbing her gently by the chin and making her face him
"Harley, would you kill for me again?"
She looked deep into his emerald eyes, replying without a pause "Yes."

Joker took a step back, shaking his head "No that's too easy, would you…would you live for me?"
Harley immediately nodded "Yes."

He moved up to her so they were nose to nose, whispering so gently it felt erotic to Harley.

"Careful. Do not say this oath thoughtlessly! Desire becomes surrender. Surrender becomes power. You want this?" she followed his gaze into the vats below as he spoke.

At this moment Harley realised what he was asking of her, to jump in, to become like him, truly become his Harley.
"I do." Came out of her mouth without her permission.

Joker pressed his lips against her bare neck, murmuring gently against the skin
"Say it. Say it. Say it, Pretty pretty pretty pretty..."

"Please?" Harley moaned in reply as his teeth lightly bit her.

The Joker pressed his body against hers, moving his lips up to her hair "God you're so good!" he exclaimed as he grabbed her waist.

Harley who was now pumped up on adrenaline and hormones moved backwards from his delicious hold, removing the hair band letting her hair flow freely, removing her glasses and throwing them away from her. She gave him one last delirious look before climbing over the rails, she breathed deeply as she stared into the chemicals below, it could kill her… but she said was willing to live for him and she meant it. With that she pushed off from the railing and felt herself fly through the air before hitting the hot, thick liquid below.

'Watch me in the swimming pool, bright blue ripples, you sitting and sipping on your Black Krystal, oh yeah.'

Joker watched her as she actually did it, what a crazy broad?! He didn't think she actually would, he laughed madly as he watched her gradually sink and turned to leave. However something in his head made him stop, was he throwing away a great opportunity here? I mean she did actually kill someone for him, his shrink for holy batman! He had worked on her so long, so much work and time gone to waste…
Joker quickly threw off his shirt and climbed over the railing, doing a swan dive into the vat of chemicals that so many years ago had made him become him.

As he felt the liquid surround him like an old friend, he saw Harley nearly at the bottom, clearly unconscious. He swam down, eventually grabbing her waist and bringing her to the top. As they hit the air, Harley gave a start, shocked to find herself alive and in his arms.

Joker looked at her closely as she got to grip with her surroundings, her skin was now deathly pale like his, her lips a dark pink hue and her hair a startling shade of white blonde, red and black dye was flowing from her clothes into the surrounding chemicals. Harley finally focused her attention on the Joker to find he was already looking at her as though it was the first time he was seeing her. She put her around his neck as he move down and kissed her so passionately she thought she was going to faint. He broke their kiss laughing and she laughed with him, crazily without a single care in the world. It was so clear to her now, how none of anything that had happened before didn't matter and never would again.

'Light of my life, fire in my loins, be a good baby, do what I want. Light of my life, fire in my loins. gimme them gold coins, gimme them coins.'

The next half an hour passed in a blur for Harley, they both got out of the vat and drove back to his hideout, dripping chemicals everywhere. She kept admiring her skin the whole way back, how flawless it seemed causing her to laugh at the madness of it all. Joker couldn't help but stare at her as he drove, she was beautiful, his masterpiece he had created, and exactly how he had planned.

As they got back to the house, all of the Jokers henchman couldn't stop staring at her, she had been… 'jokified'. Joker waved them all off as he guided her into the house passing the hallway which was now clear of a body, the blood stain still on the floor. He took her upstairs to a much nicer plush room than the one she was in before, his room she realised.

Joker began taking his shirt off as she admired the room, velvet curtains, plush purple bed, theatre dressing table covered in various guns, hair gels and money.

She jumped as she felt Joker press up behind her, his hands landing on her waist "Would you care for a shower, my perfect girl?"

'And I'm off to the races, cases of Bacardi chasers, chasing me all over town 'cause he knows I'm wasted, facing time again at Riker's Island and I won't get out'

Harley felt her nipples harden underneath her bra, which pressed out against her shirt. She was still soaking and getting cold. In response Harley began walking to the adjoining bathroom, unbuttoning her shirt as she did, letting it drop to the floor before looking at Joker who hadn't moved a muscle. His jaw was clenched, eyes wide and fists tight he followed her into the bathroom. As soon as the door was closed, Harley looked round the bathroom realising it was a modern wet room, it was massive. She felt deft fingers undo her bra, letting it fall to the ground, Joker moved round her to turn the shower on, steam soon filling the entire room as the hot sprayed against them. They were both still wearing trousers she noticed as he looked her body up and down. Harley could feel herself become wet at his intense stare, her nipple harder than they had ever been before. Joker with an animal growl, pushed Harley against the wall, arms either side of her, kissing her fiercely, water pouring over them.

'Because I'm crazy, baby, I need you to come here and save me. I'm your little scarlet, starlet, singing in the garden. Kiss me on my open mouth, ready for you.'

Joker moved so they were skin to skin, feeling her delicate and soft breasts against his firm chest was sending him wild. He hadn't felt such a need for someone else before, this both infuriated and intrigued him but for now he just gave into the moment. He moved his fingers to her jeans, unbuttoning them quickly, kissing his way down her neck, across her breasts and down her stomach as he pulled the jeans off of her and tossing them aside, leaving her just in her black lacy thong. Harley whimpered at every touch and every kiss he made across her body, as he knelt before her she looked down, the warm water fuelling her arousal. He looked at her as he gently pulled her thong down until it was off of her, before he gently pushed her legs apart and tasted her for the first time. Feelings exploded within Harley causing her to moan his name loudly throughout the bathroom as his tongue rubbing circles against her clit, she could feel herself dripping down her legs from how wet she was but this was less obvious with the shower. She was slightly ashamed of how much she needed this, how much she needed him to touch her, play with her and just be with her, but once again the feelings completely overwhelmed any thought process.

Joker could feel his cock strain in his trousers as he tasted her beautiful pussy, wet and ready for him. Her moans just drove him crazier, he needed her right now. Joker moved up so he was once again face to face with her, undoing his trousers as he kissed her, letting her taste herself on his tongue. As he pushed his trousers off and flung the wet pair across the bathroom he felt a small gentle hand firmly grip his cock and start moving it up and down. "Fuck" Joker whispered as her experienced fingers made him even harder which he didn't believe possible, as she continued to play with him, a small smirk showed on her face. Joker pushed her all the way back into the wall as she continued to play with him faster and harder. Joker began roughly biting her neck in between his moans, causing her to whimper with both pain and pleasure. Joker quickly pinned her hands above her head leaving them there before grabbing her legs and wrapping them around his waist, quickly plunging his length into her as Harley screamed his name at the sensation. He was long with a nice girth and as he quickly pumped in and out of her, he was hitting all the right spots.

Within minutes Harley felt herself hitting the edge "Oh fuck Mister Jay, fuck I'm going to cum." She moaned right into his ear causing him to growl in response and pick up the pace even harder. Harley screamed as she came on him hard, gripping down on his cock, the tight sensation and noise was enough for Joker to finish as he moaned her name into her neck.

As he let go of her legs, he kept a firm grip on her waist to prevent her falling over. She was exhausted and spent, after quickly finishing up in the shower, Joker carried her into the bedroom, dressing her in some spare pj's and putting her into bed. Harley nearly fell asleep as soon as her head hit the pillow. Joker grinned over her sleeping form, turning the lights off and leaning over to her ear and gently whispering "You're all mine now Harls and you always will be. Sleep tight, my Queen."

That night Joker slept better than he had done in years.

'Light of his life, fire of his loins, keep me forever, tell me you want me. Light of your life, fire of your loins, tell me you want me, gimme them coins.'

Okay also some personal insight to why I am writing these two the way I am. I have been a fan of these two as a couple for 7 years now however I am fully aware of how twisted it actually is. In my personal belief, the Joker does love her in some way, not in a healthy way but he's entirely obsessed with her. She is his possession and in his eyes he completely owns her however that doesn't mean he doesn't care about her deep down and want her around as she is the only woman to ever get close to his level. I still entirely stick by it's a toxic relationship but I like to think they had some sort of tender moments even if they are to psychologically mess with her. (I do not and never will endorse domestic violence in any form, it is never okay to be controlled or abused by your partner.) Please review! Constructive criticism is more than welcome and I hope you enjoy!
