"Stop squirming," Nikola growled, his voice still tinged with a vampiric edge. Helen shot him a dark look and pursed her lips from across the airplane. She crossed her legs and looked away from him, trying to find something very interesting about the small, dark window. In reality, there was nothing on earth that could truly take her attention from Nikola at this point. He was still transformed, eyes dark, teeth misshapen and voice distorted. He should have been terrifying to her like that, he should have made her want to go sit up with their pilot but instead she had found herself staring at him every chance she got.

Of course, Nikola kept catching her and giving her knowing looks in return. He'd even taken to letting his eyes rake up and down her body greedily in reply, knowing she couldn't tell him exactly where he ought to shove his glances. It frustrated her to no end yet she couldn't very well stop herself from looking at him whenever she could.

He was stunning and dark and evil rolled off of him in waves but then again, Helen had been mercilessly teased time and time again for her want of a 'bad boy'. She argued against the notion entirely, certain that her few conquests didn't deserve such a label but watching Nikola... Well, he was bad. Very bad. Dark and bad. Dark and bad and wearing a suit. The fact that he was covered in grime didn't hurt either. It sat in such beautiful contradiction to his normally fastidious nature that Helen was unable to stop herself from letting her eyes linger on the streaks of blood and dirt covering his cheeks.

"I said stop squirming, Helen," Nikola said again, frowning at her.

"Why do you even care?" she snapped in reply. "I thought you were still angry at me for bringing the restraints."

"I never said I was angry," he replied evenly, giving her a wide grin that exposed all his teeth. "I merely thought it was interesting that you brought vampire proof restraints on our trip. Have you developed psychic abilities recently?"

"Old habits die hard," she retorted, rolling her eyes. For years she'd had to make sure she almost always had a set of vampire proof restraints on hand, just in case and that wasn't something she'd been able to give up in the few months he'd been 'devamped'. Part of her wondered if it was because she was unwilling to actually accept that he would die a human, mortal death eventually.

"Stop squirming," he suddenly said again, frown deepening.

"Oh leave me alone," Helen muttered, shifting in her seat so that she was looking out the window again. Nikola groaned, his head thumping back against the seat as he yanked at his restraints.

"You're killing me," he growled.

"Drama Queen," Helen said with a sigh.

"You really don't understand how torturous this is for me," he muttered, shaking his head. "Can't you go... relieve yourself?"

"Excuse me?" Helen asked. Nikola looked pained and almost a little embarrassed at his words though she couldn't put her finger on why.

"I can... I can... You need to stop squirming."

"Is it my fault the seats aren't comfortable?"

"Go sit somewhere else then."

"I need to keep an eye on you," she tried, hoping she sounded confident and assured of herself.

Nikola scoffed.

"I can smell you," he finally said, lips quirking into a small smirk.

"Smell me?" she echoed. "I thought I patched up the blood."

"Not your blood," he said darkly, eyes once more raking up and down her body. Helen shivered slightly in her seat and Nikola groaned again, nostrils flaring as he fought his restraints again.

Then Helen understood.

"Oh."

"Go sit with the pilot," he said tightly. "Once I get some medication, everything should be all right."

Helen bit her lip, watching Nikola. She wanted to deny his accusation but the fact that he wasn't acting smug made it almost impossible. He wasn't taking advantage of the situation, a line of attack she wasn't exactly familiar with. Granted, he was tied up which made it a little harder for him but his eyes were still closed, head pressed back into the seat as long taloned hands gripped the armrests tightly. His jaw was straining too and suddenly Helen wanted nothing more than to nibble on the cords of his neck.

She squirmed again in her seat and Nikola groaned, stiffening further.

"Helen..." he said in warning.

Helen unclipped the seatbelt that lay low over her hips.

At the sound, Nikola's eyes snapped open.

"Helen?"

"You will never speak of this again," she said softly, rising slowly from her seat. Nikola's eyes grew wide. He'd brought her so close to unspeakable pleasure before and now she could think of nothing more than getting what he had so cruelly ripped away from her.

"Helen?"

"Never. Understand?"

"Helen?"

"This isn't happening," she continued, crossing the small distance between them, smiling when Nikola swallowed. The decision was a rash one but Helen was surprisingly comfortable with it. She would get her kicks and Nikola would get his and then they'd both go back to living a normal life. It had happened a few times before and even then, she could never find it in herself to regret it. Nikola was a most satisfactory lover and, given his newly immortal state, she was more than happy to sleep with him once more. After his devamping, she'd made a point of avoiding such things, lest either of them get too attached. If they had the rest of eternity to figure things out, it took the pressure off significantly.

"Helen?" he tried again, fighting at his restraints as he leant further back in the chair, trying to avoid her.

"And I want you to talk to me, all right?"

"Helen!"

She smiled, coming to a stop just before his legs. She hadn't bothered to restrain his lower limbs, instead linking together the few restraints she had to keep his arms secure. Leaning forward, Helen reached for his cheek, letting her fingers drift across his skin before trailing her hand down his chest. With a smirk, she flicked her wrist, undoing button after button until she had both his vest and shirt open.

He was just as defined as she remembered and she hummed happily as she ran her hands down his chest. When her hands reached the waistband of her pants she smiled, looking up at him.

"Are you going to stop complaining now?" she asked softly. Nikola said nothing in reply but the incessant tugging on his restraints stopped and she took it as a good sign. Before he could blink, Helen straightened, tearing off her jacket and popping the button on her jeans. Nikola let out a choked little sound but said nothing and Helen let her eyes drop to his lap, her heart rate picking up at the bulge she saw.

Her hands trembled as she reached for his belt, fumbling with it until she could yank down the zip on his fly. Nikola gasped, hips twitching in the seat as Helen reached into his pants, fingers diving beneath his boxers to wrap her hand around him. She looked up, watching his eyes flitting closed in pleasure as he let out a strangled moan. Carefully, she extricated him from his pants, one hand stroking softly as the other ran back up his abdomen to grab onto his shoulder.

"God," he breathed. "Helen. Helen, please."

"Please what?" she breathed in reply, leaning in and pressing her cheek to his.

"Let me up," he whispered in response. "Let me touch you. Let me hold you. I can't... I can't..."

"I'm afraid you're too dangerous for that," she said with a sigh. Of course, it was only partially true. Under normal circumstances, she wouldn't release him from the restraints when he was in a state like this but, in terms of the fact that they were getting naked, she couldn't risk letting him carry her back to the tiny bed, well aware that he'd find a way to keep her there for a good few hours. And then probably take her back to her bed in the Sanctuary, having devastating results not only on her ability to work for the next few days but also on her reputation. Nikola was slightly obsessive at times and when he got Helen into bed, it was no exception.

"Helen," he half cried, jerking at the restraints. She merely shook her head and stepped back, not giving herself time to admire the site before her. Instead, she hastily she toed off her boots, ripping down her socks before shoving her pants off of her hips.

A brief flash of embarrassment streaked through her but simply looking back to Nikola was enough to calm her slightly. Without thinking any more about it, she launched herself at him, straddling his hips as one hand wound into his hair. She tugged his lips to hers, pleased when he came more than willingly and their mouths met in a messy kiss.

At the simple contact, any lingering apprehension Helen harboured disappeared. Nikola was warm, his body pressing up against her as much as his bonds would allow. She smiled into the kiss at the thought, enjoying that, for now at least, she had him completely at her mercy. His erection dug into her abdomen almost painfully as her hips moved against his and Helen moaned against his lips, pulling back just enough to suck in a lungful of air before diving back in.

"Helen," he growled against her lips. "Helen, you need to... need to..."

He groaned again, thrusting his hips as much as he could, making Helen shiver. His desperation turned her on more than it really should have though she didn't dwell on it.

Instead she reached down between them, stroking his cock roughly enough to make him whimper.

"If you don't speed this up, I'm afraid you'll end up mightily disappointed," he huffed, pulling his mouth free of hers. There was a wicked gleam in his eyes that made her shiver against him, her hand tightening dangerously around him and Nikola hissed, shuddering.

Helen decided in half a second that she'd had enough teasing and brought her free hand down between them, pushing aside her panties as she shifted forwards. They both moaned as he brushed against her, Helen's resolve faltering for just a second. The reality of what they were about to do hit her like a ton of bricks. She couldn't do this, could she? Nikola was still restrained, for heaven's sake. Why was she knelt over him, his erection in her hand as she panted against his cheek? They couldn't do this.

Not even the strangely erotic moment they'd shared back down in Afina's chambers could justify something like this. Sure, she couldn't remember being more turned on so quickly ever before in her life but that didn't mean she ought to jump Nikola's bones. Especially not like this.

"My God," Nikola huffed, head bowing forwards. "Your shirt. Please. I need..."

And with that Helen's fears fell away. He was at her mercy, completely surrendered to her control and she loved every second of it. Smiling, she pushed back from him just enough to flick open the buttons of her shirt, revealing the slightly sweaty tops of her breast. Nikola moaned again, his head dipping to seek out her cleavage and she bucked her hips. His gasp of pleasure was muffled against her chest but she caught the tail end of a dark curse slipping through his lips.

With a tiny smirk, she shifted her hips, lining them up before sinking down on him slowly. Again, he started to swear, this time almost howling the curses to the roof and Helen was close to joining him. He was big and hot and the way his hips twitched as she lowered herself atop him made her groan in pleasure, her body fluttering around him as she tried to accommodate his size.

It truly had been too long since they'd done this.

"Helen," Nikola breathed, eyes locked on hers. The darkened orbs before swirled away momentarily, leaving her staring into his icy blue eyes and it was as thought he was professing a thousand love poems to her all at once. He looked at her with such deep and untainted adoration that she almost wanted to stop. It was unfair, she realised dimply, to do this to him, to tease him with what she could never give.

Helen didn't do relationships, she never had. She could do kinky vampire sex in an aeroplane, she could do kinky sex in a tiny broom closet if need be. Hell, they'd even done kinky sex out in the gardens of the London Sanctuary once but she didn't do more than that. Even with James she had been reluctant, pushing him away until she was able to take from his the physical pleasures she needed whilst giving him something at least vaguely resembling an honest relationship.

But with Nikola... He made things messy. She couldn't give him the adoration he gave her and nor could she give him her heart though it was clear he seemed to want to give his to her. It was a strange and unkind conundrum but Helen loved him in her own way and moments like this, while wholly unfair, were all that she could give. It was on her terms and in her way but that was something she just couldn't help.

So instead of dwelling on it further, Helen simply bit her lip and threw her head back, revelling in the sensations that rushed through her as she began to move slowly. Nikola was panting against her neck again, his sharpened teeth nipping at her flesh in a way that told her his vampiric eyes were back but she couldn't bring herself to care. She'd been so close back in the stone chamber and now her body was demanding satisfaction that only Nikola could give.

Helen gasped as his lip managed to close around her nipple through the fabric of her bra, clenching around him tightly enough that he groaned against her breast in response. It was a heady thing to realise that her body held such a power over his and something Helen found she was quite enjoying. Not that she was surprised that she got off on power. Nikola had teased her one too many times about it.

She was about to make some comment to that effect when his hips thrust up beneath hers, pressing into her at just the right angle that it had her crying out.

"Again," she cried, unable to keep from speaking. Her hips moved faster against his, each thrust sending her closer to the edge of delirium. She could just about hear him jerking at his restraints as he struggled to comply, the faint sounds just making it over the roar of blood in her ears. Nikola's lips moved up her body to her neck, sucking harshly at the juncture between neck and shoulder.

He was muttering against her skin too, she realised, barely managing to pick up that the words were foreign. Though she knew she probably knew the language, she didn't give it a second thought, instead working harder and harder to achieve the orgasm she could feel just out of reach.

"Nikola!" she moaned desperately.

"Fuck," he groaned. "Fuck, Helen. Come for me. Please, come for me."

And so she did. For all that she enjoyed holding the power, the desperate note in his voice made her willing to do just about anything. The pleasure rushed through her in a second, her entire body shivering as she clung to his shoulders. He was muttering something again, this time just against her cheek and she turned her head, cutting off whatever stream of words he was producing with a sloppy kiss. She continued to ride him with what little strength she had left, determined to bring him the pleasure he'd brought her.

She was rewarded for her efforts just moments later as he stiffened against her, roaring out her name and sending another little wave of pleasure through Helen's sated body.

She knew she should move, that eventually she'd have to shift from his lap and clean them up but, for one lovely moment, Helen let herself slump forwards against him, her head landing on his shoulder as pleasure and exhaustion overtook her.

"Never mention it," she murmured one last time, not sure if Nikola heard but not entirely sure that she cared.

After all, he was still at her mercy.

Yay! This one is done :D How exciting! Next is my rewrite of 'Out of the Blue' despite the fact that Nikola wasn't in that episode. I had fun with it though so that's what matters!

Thanks for the reviews, they made me smile :D
