So this is an AU, with criminal Felicity and a meaner, much darker Oliver.
*****
She ran for her life in the darkened warehouse, certain this was it. Today would be the day she died.
She wanted to beg and plead, but she'd heard of this man. He couldn't be reasoned with, at least not by people like her. So she ran for the back exit that she was sure had to be there. But she must have taken a wrong turning somewhere, because in front of her was only a blank wall. And behind her were footsteps coming to a halt, and the sound of a bowstring being pulled back, to maximum tension.
When she turned around, a tall figure in green, hood shadowing his face, was in front of her, aiming an arrow at her heart.
"FELICITY SMOAK. YOU HAVE FAILED THIS CITY!"
How did he even know her name? She'd used a fake name for everything! She thought she'd been under the radar!
"Please don't kill me! I'll do whatever you want!" She tried to reach him, even though she knew it would be useless.
"Return the money you stole. Do it now!" His voice was too deep to be natural - he was using some kind of modulator. This occurred to her before the meaning of his words sank in - she couldn't do that!
"They'll kill me!"
An arrow buried itself in the crumbling concrete next to her head, and she screamed.
"That's not my problem."
He pushed a tablet into her trembling hands and she quickly started the programs which would reverse the transactions she'd done. Every time she looked up from the tablet, he was standing there, looming over her. Finally, she was done, and she told him that. He grabbed the tablet and turned to walk away.
"Wait!" This was her last chance, and she was taking it.
He stopped, but didn't turn back around.
"They're going to kill me. You know that. First they'll torture me for a few hours. Or maybe chain me to a bed and fuck me for a few days. If I'm lucky, they'll kill me then."
"So? Why should I care what happens to you?"
Because you gave me three or four chances, Felicity thought. Because you want something from me, or else I'd be dead already.
"Maybe we can make a deal," she said, tentatively.
He turned around and stalked towards her, forcing her back up against the wall, so close that she had to crane her neck to look up at him.
"I don't need your money," he sneered.
"You're in luck, 'cause I don't have any!" Temper, Felicity, she thought.
She looked up at him, biting her lower lip, and carefully pushed him away. As soon as she touched his chest, she realised that something she was doing must be having an effect. He was warm, and was breathing fast, though he hid it well.
Good thing her hair was down. She started unbuttoning her blouse, and unfastened her bra at the same time, pushing them both off her shoulders. And he swallowed. She actually saw his Adam's apple moving. Now he's going to try and deny it, she thought, and she had to be ready to take it to the next level. She snuck a look at his groin - yup, that was an erection. A big one, if she wasn't mistaken.
"What are you doing?" His voice still sounded harsh, electronic, deep. But he wasn't walking away, or stopping her.
Instead of answering, she hooked her thumbs into her waistband and her panties, pushing them both off at the same time, and then stepping out of them. Then she looked at him through her lashes. Your move, Robin Hood.
He stalked towards her again. Oh shit, Felicity. He's either going to fuck you or kill you. He slammed her against the wall, and pulled down a hanging chain she hadn't seen, until it reached its end. He tugged down a couple times, to check it was secure, she guessed, and lifted her arms.
"Hold on to that and don't let go."
Oh god, he was going to do it. He'd taken the bait.
She heard his zipper go down, and her breathing grew faster, but she didn't dare look, at first. He must have taken his gloves off too, as when his fingers slipped into her pussy, they were bare. God, she was so dry - she snuck a look down at his cock - and he was enormous. He'd tear her apart.
Except he was playing with her clit, occasionally flicking it, slipping his fingers in her and fucking her with them. So he didn't want to hurt her. Not much, anyway. She was getting wetter, and soon the only sounds in the warehouse were their combined breathing, and the wet noises of his fingers moving inside her. And her sudden squeal as she came. When she could see again, he put his hands under her thighs and lifted her so that they were eye to eye.
"Put my cock inside you."
