Fandom: Birds of Prey [the Movie].This fanfiction is listed under the Comics category since the movie is not an option yet. The story line I follow is not in the movie itself, so basically there will be no spoilers.

Pairing: Roman Sionis /Black Mask x Harley Quinn.

Rated M for mentions of torture, violence, adult themes and language. It's a dark verse to begin with, so you've been warned. May contain some hints of non con/dub con.

The story begins from Harley Quinn's point of view. I plan to write from Roman's POV in subsequent chapters, too.

Harley's POV:

Harley Quinn wanted to enjoy a peaceful evening all to herself, with her favorite egg sandwich. She hasn't had that in a long while.

This time the entire city was after her, she couldn't catch a break, could she? Mercenaries and whatnot on a hunting spree for her head.

They all seemed to want her dead, including him. Roman Sionis.

Harley took her sticky clothes off and ran a bath for herself, she really needed to relax after the encounter she's had with Roman and his goons. They've negotiated for retrieving the diamond, and she'd have to get to that soon.

What other choices did she have? She didn't want to end up with her pretty face peeled off like the rest of them, as he put it. If Roman decided to kill her off, Harley couldn't count on Mr. J's protection anymore.

Harley scrunched up her nose pushing the bad thoughts aside and poured herself a glass of red wine. Taking a sip, she enjoyed the foam bubbles soothing her tired body and easing the pain in her muscles. She was a slim fit woman, and didn't hesitate to fight when she had to, but sometimes her body would get really tired.

Finally, she'd started to feel like drifting off from the relaxing foam working wonders on her, when there was a rapid knock at the door of her apartment.

"For fuck's sake! Who is it?",She yelled from inside the bathroom, but didn't receive a reply.

Just when she thought the visitor had given up, another series of rapid knocking on the door followed.

"Jesus Christmas!", Harley cursed under her breath, groping around for her towel to cover up.

She checked with the clock on the wall.

8 pm.

Who would be around at this hour anyways? She didn't exactly have friends and given her current status of a single woman, she didn't expect to see anybody pleasant.

Drying herself off on the way to the door, she's then wrapped the towel around her body, blonde hair still damp and messy.

"Oh my. I've heard it's a lucky charm to spot a harley quinn without clothes on, whew!"

Roman Sionis, standing there with a Cheshire smile.

Fan-fucking-tastic!, Harley thought.

She expected to see anyone but him, and had to count to ten slowly before she'd snap.

Sarcastic asshole.

"Romy!," Harley exclaimed, big fake smile spreading on her painted red lips.

He was wearing a handmade Italian dark blue suit, VVS cuff-links and handmade leather shoes, suddenly she felt rude to stand there only in a towel and wanted to cover herself up from head to toe.

"What are you doing here, I thought we had it all settled?"

His piercing blue eyes were ogling her body and she felt very tensed from his glances.

Harley has never looked at Roman the way she saw Mr J, but she had to admit he could be quite charming and handsome, if and when he wanted to be.

He wasn't clean shaven, but the stubble added an edge to his refined look, the eyeliner he had on made his cobalt eyes sparkle. She loved boys who wore eye make up.

Harley what the hell are you thinking about?

She must have been lonely for some time now since she felt the sudden need for a man between her legs from the mere sight of this narcissistic prick staring at her lady bits.

"Well?", Harley Quinn prompted him to speak.

However irritating he might be, she had to be polite, so she gestured him to come inside and went over to the kitchen to pour herself another glass of wine.

Harley could feel him follow close behind but she was so tired from this day, at this point she didn't care if he'd pull out a knife and stabbed her in the back. Which she hoped he wasn't going to actually do since he was alone, and not with his henchmen.

"Listen, Romy, if you'd come here to taunt me more, I-"

She had turned around to face him again, and Roman had planted a smooth kiss on her side, his stubble scratching mildly.

"What are you do-",

His hands were now on her waistline, he kissed her other cheek softly and his lips went slowly down to her neck.

Sudden tingly sensation spread all over her from his mouth leaving wet trails on her bare skin.

"I saw you looking at me, Harley Quinn. You like me, " He concluded in a low, raspy voice, as he gently bit the skin below her ear.

She almost squeaked on hearing this, her hands grabbed onto his shoulders attempting to push him away.

"I.. Don't!", Harley protested vigorously.

Nevertheless Roman went on peppering kisses all over her collarbones and smirked.

"Oh, you don't? Well. Why haven't you kicked me in the balls yet?"

"Because..."

Because her body was feeling all weak, she was like jelly in his arms. He smelled so good and he was warm.

On instinct she had wrapped her arms around his shoulders, instead of pushing him away.

"Yeah, that's what I thought," Roman taunted as he slowly discovered her body under the towel.

"Why, I'll be damned..you're quite as pale just everywhere!", He exclaimed with excitement, two perky tits with pink rose buds pointed at him sprung into view.

Goosebumps spread all over her naked skin from his cheeky tone. Hideous bastard.

"What are we gonna do with these hard nipples, hmm, Ms. Harley?", He raised a dark blond brow teasing her, before putting one of them into his mouth, and sucking it hard.

"Fuck me!", Her nails dug into his scalp as he tortured her with his mouth deliciously alternating between sucking and biting the sensitive buds.

"Sounds like a plan," The rogue chuckled softly, before pushing the towel out of his way, letting it fall down.

All that was heard from her was a whimper of pleasure, a non verbal plea for him to continue.

"Nice tattoos," He observed on examining her perfectly pale body with his burning cobalt eyes.

Roman's gaze then fell on her already soaked pink pussy.

"Allow me."

He knelt before her, his hands covered with fancy leather gloves gently spread open her soft thighs and he sank his head between her legs.

By the time he had started working with his mouth, Harley could only pant and moan loudly, openly enjoying the manifestations of his tongue rolling over her clit and soaked folds.

She was pushing her hips forward, forcing her heated center more and more into his mouth, as she could feel she was close.

Very close.

And then he stopped.

Harley couldn't believe that he did it to her but he just casually stood up, wiping her taste off of his mouth with the back of his fancy leather gloves , and smirked.

"I think that's enough for a start," He spoke calmly as if he didn't just denied her an orgasm.

Fury slowly taking her over as she stood before him, hands balling into fists of anger.

"Roman, I swear I will kill you!", She shouted at him raging, still standing bare naked before his incinerating blue gaze.

Roman shook his head and laughed.

"No, you wouldn't. You'd want me to finish what I just started, and I will eventually. You taste so fucking delicious, Ms. Quinn."

He licked off his bottom lip as he said that, observing her flushed face.

"Just not tonight. Call me old fashioned, but I like to take my women out first, before I fuck them. We're going to dinner. "
