Emma Swan had never been one to care about species taboos. That's probably how she found herself pressed against the wall in the alleyway behind the infamous Noblesse nightclub with a vampire's tongue down her throat and her legs wrapped around his waist.

A witch herself, it happened to be her job to track down other supernatural beings who broke their laws and needed a bit of.. coercion. This particular mark had been dancing around her for years and never missed an opportunity to flaunt his misdeeds around her. Shes not sure how the heated stare-down in the nightclub had led to her current situation but when he groaned against her open mouth again, she couldn't find it in herself to care.

One of her hands tugged on his dark hair and the other trailed down his leather-clad back, pulling his hips into hers. She needed friction. He finally opened his eyes and pulled back. She tried to contain the whimper in her throat and even out her breathing. He grinned at her and the way his long white fangs glinted in the streetlight combined with his smug expression made him look positively sinful. Good thing she was prepared to sin tonight, she thought.

A sound in the street reminded her they were still in public, which she was quickly growing tired of, and she snapped her fingers. They both disappeared in a cloud of smoke.

The first to get her bearings, she stepped back from him and watched his face when he realized where they were.. her apartment. Specifically her bedroom.

"A little eager are we, darling?"

"Killian, just shut up unless you want me to teleport your ass into jail tonight instead," she cursed herself because her shaky voice betrayed just how turned on she was right now.

He clearly caught on and smirked again, "Oh believe me lass, I'm right where I want to be," he whispered in her ear before leaning in again. Emma grabbed the lapels of his coat and crashed his lips to hers for another scorching kiss. He tasted like nothing she could describe, she only knew she wanted more. She pulled on his lips with her teeth and his hands tangled in her hair. Her breath was ragged and the temperature in the room was rapidly rising. At this pace she thought she wouldn't last 5 minutes once they got their clothing off.

Thankfully, he was just as affected as she was. His pupils were blown wide and his hands left her hair to wander every inch of her still clothed body. When one came around to palm her breast she gasped and arched into his grip. Not wasting any more time, she started pushing his coat off his shoulders, needing to touch more. To feel more.

He quickly complied and walked them back towards her bed, stripping clothes as they went. They spoke in between desperate kisses. She almost felt lightheaded from want. Her blood was rushing in her head and she caught his gaze sliding down her body appreciatively. Already he was nearly stripped of his vest and pants.

"I assume everything down there still works? What are you, five hundred?"

"Swan, you wound me, im not a day over three hundred. And I promise you, im more than functional." He said the last word like he knew exactly the effect it would have on her. His voice dripped sex and she wanted him bad.

Finally stripped to nothing but her panties, she fell back onto the bed where he quickly followed. She took the opportunity to ogle him. His pale skin was unmarred and his body taunt with muscle. Dark hair covered his chest and trailed down to between his legs. She felt desire coiling in her stomach at the sight of his arousal straining through his boxers and she couldn't help but lick her lips. When he covered her body with his own and brought his puffed lips to hers again she stopped thinking at all. The kisses were sloppy and rough this time, his fangs grazing her lips and her hands again found themselves buried in his soft hair.

Then Killian was kissing down her neck, fangs dragging along her heated skin. He stopped at her breast and looked ready to devour her whole. His hand came up to lightly pinch one nipple and he wrapped his mouth around the other. His hot mouth latched on and she danced on the line between pleasure and pain. The light nipping and twisting was driving her mad with lust. Heat shot straight to her core and she knew she was already soaking through her panties. She could feel him hot and thick against her thigh even as she arched into his touch. He let go and gazed up at her with a look that could only be described as hunger. He continued kissing down her body, biting lightly in some places, and she couldn't suppress the tremors running through her body.

When he reached her panties he ran one long finger right down the center and she almost jumped off the bed. He started pulling them down immediately and she helped kick them off, the anticipation making her see red. He spread her legs and brought his face right down to her slit, inhaling appreciatively before giving it a long lick that made her gasp.

"You taste heavenly, Emma," he murmured before diving in with vigor. Emma bit her lip to keep from whimpering. Killian's mouth was relentless. He nibbled at her folds and licked circles around her clit. Her hands wrapped into his hair and it was all she could do to keep from forcing his face into her. He took her clit into his mouth and she felt him hum with pleasure himself, almost fainting from the sensation. His expert tongue alternated twisting into her and sucking her clit, and she was almost over the edge. He brought up one finger and then two, pressing them into her slit with a practiced flourish. Her eyes rolled back. He sucked and kissed and curled his fingers one more time and she was flying, her orgasm like fire through her body. She shuddered, boneless already, and he was pulling away.

He removed his own boxers now and looked at her with such desire that she already felt herself coming back to life. His long dripping cock bobbed below him and he grinned, climbing back up her body. The smug idiot was dragging his length against her nether regions, teasing her again. Pushing just the tip to her entrance before moving back. His cock already glistened with her release and her mouth went dry. When he lined himself up, she looked right into his dark red eyes. She curled her legs around his back and rocked her hips, craving him. She started to tell him to hurry the hell up when he sheathed his entire length into her at once, stretching her deliciously.

She saw stars. He started at a brutal pace, the thick drag of his cock on her walls more than she thought she could handle. She gave as much as she took, rocking her hips to crash into his with every thrust. He whimpered when her legs dug into his backside, pulling him deeper into her warmth.

"Gods Emma, I'v had my fair share of sirens but I think you outrank them all," his voice was deep and throaty in her ear. "So bloody hot, and tight." His entire body was taunt with need and she had her arms wrapped around his neck, just trying to hold on. Every thrust hitting exactly where she needed him. His movements were rough and she urged him on, wanting more. "More, please, Killian oh my god," She felt herself winding up again, her entire body starting to twitch and she just needed him right there-

Just then he slowed down, and before she could protest she felt his hot breath raising hairs on her neck. His fangs grazed her throat and he inhaled. He moaned against her and had slowed to deep, languid thrusts. His hand was at her hip, pulling himself deeper as he nuzzled her neck. "Emma.. can I.." He sounded wrecked, desperate.

She instantly realized what he wanted and let his hand curl around the other side of her neck to gather in her hair. She raised her chin to give him better access and shes pretty sure she started to nod when he sank his fangs into her and she had no more room for coherence.

Light. Hot. She thinks someone keened but shes not sure. The most intense pleasure she had ever felt shot through her entire body and gathered at her core, and she could still feel his cock grinding deeper into her as he sucked at her neck. He gripped her tightly and her nerves felt like they were on overload as she came once again. Her entire body arched into his. She couldn't think of anything but him, thick inside her and his mouth at her neck. It was like someone poured liquid lust into her veins, she couldn't even move. Something similar to his name ripped from her throat and she clung to his shoulders as he drove into her relentlessly.

All at once it stopped for a brief moment and she almost mourned its loss before he bit into her again and it started even brighter than before. and again. and again. Each time accompanied by his ever more erratic thrusts. It could have been hours she felt like this, it could have been days. The only constant was the pleasure, oh god the pleasure. She never wanted it to stop. She was so far gone she barely registered his pulsing white hot seed deep within her and his body relaxing until he had let go of her neck and went limp on top of her.

She could barely breath as she came down from the high. Spots were at the edge of her vision. He pulled out of her after some moments, catching his own breath, and she made some effort to sit up. Killian's arm came across her chest just as her vision started to darken and pulled her down on top of him.

"Rest, lass, I think I took a bit too much." He was hoarse. She turned with what little strength she had and looked at him. His eyes were as red as she had ever seen them, and his lips and fangs shone with blood. Her blood, which he was licking from the corners of his mouth. His expression was one of contentment and she had to imagine hers looked the same. She threw an arm over his chest and let herself relax, not that she could have moved anyway. Her body still twitched as if from aftershocks.

When she trusted herself to speak, his eyes had already drifted closed. "I'v heard the stories about vampire venom but holy shit. That was beyond what I think I'v ever heard. Is.. Is it always like this?" Even so, her voice came out barely above a whisper.

He chuckled warmly and then thought for a moment before speaking. "Not quite. I'm not sure what happened there. Yes, vampire venom is an aphrodisiac. You being a witch are obviously immune to its.. other purpose.. and cannot be changed. But its never been nearly that intense before.. there are a couple possible explanations for that but I'll explain in the morning, for now, I think I need sleep before we both keel over." He licked his lips again, which she found strangely erotic even in her current state, and pulled her closer.

"Mmmm," that was a good enough explanation for her right now. She was so drowsy she was finding it hard to put thoughts together anymore. The most delicious kind of bonelessness permeated her body and just this once she allowed herself to cling to his warm body and drift into sleep.
