Author's Note: Minor canon divergence. Minor headcanon for 5b events woven in. Rated M for language and sexual content. This is my first written work in many years so reviews are much appreciated.

This is also my first time writing smut, some of which you'll find at the end of this chapter. If that's not your cup of tea, please skip to Chapter 2 after the point in this chapter that Emma finds Killian.

I hope you enjoy reading this as much as I have enjoyed writing it.

Edit: I have made some small changes to the story from when I originally posted it so you may want to re-read the story.

Storybrooke

The wind swept leaves into the hallway as Emma threw open the side door to her house. It was supposed to be their house, she thought ruefully. Emma tried to focus on Killian and what HE would do now that he knew she had given him the powers of the Dark One. All because she couldn't bear to lose the man she loved. Again. Not when she had finally embraced all that a future with Killian would mean.

"What future? There's no future for us now!" He had shouted at her his eyes wide and angry over her betrayal. She couldn't bring herself to reflect on the rest of their exchange. He had taken her memories of his plan and the dreamcatchers with everyone else's memories, leaving her with every other painful part of their exchange burned into her mind.

Emma knew that her parents would normally tell her to have hope, but clouded by the Darkness, it was hard to see how it was even possible. Ultimately being the Savior meant restoring happy endings for everyone. She knew there had only been one choice to try to give Killian a chance at a happy ending, even if it was a selfish choice, at least he was alive. She had turned him into the thing he hated for so many years so he had shut her out in his pain, letting the Darkness in, and now she was truly cut off from everyone she loved. Emma simply felt hopelessly lost and alone. Some Savior she was! Unable to sleep, unable to use magic because of Zelena's cuff, she lay down on the couch and did the only thing left to do: cry.

3 Weeks Ago - Camelot

Killian couldn't believe what she had done. He'd begged her not to do it. He would rather be dead then to be the Dark One.

"You know you'd really rather survive. Surviving is what you do. Now you can't be killed, dearie. So I would say you owe the Dark Swan," the apparition drawled as it took on the shape of a much hated crocodile.

"Go away Crocodile! I will not give into to you!" Killian screamed. And for the briefest of moments, he thought he'd rid himself of the voices in his head.

"You want to embrace the gift you've been given. You will embrace it and I'll be here to guide you until you do."

Rumplestiltskin's personage loomed before him. Taunting him. Tempting him to embrace it. To fully become that which he despised most of all. But he had loved Emma, even as she had become the Dark One and she had felt the alluring pull of the Darkness. Emma. She had done this to them. What possible future could they have now as Dark Ones? He had begged her to let him die and she hadn't. The Crocodile was right that he was glad he had survived even though he wasn't happy about the way it came about.

"Don't agree with it, fight it!" he chastised himself. Killian lost complete track of time as he wrestled with demons. The voices kept changing as each incarnation of the Dark One coaxed him closer to acceptance.

"You'll be able to take your vengeance. We have the means to do the one thing you've spent centuries trying to do. Kill Rumplestiltskin," one voice said.

"I know you're lying. How am I to get my vengeance when I'm here and Gold is in Storybrooke," Killian said, wondering out loud.

"Might I suggest a Dark Curse. Quite effective," Rumplestiltskin's form said as it appeared in front of him.

"And crush the heart of the one I love the most to enact it?" No," he said pushing the thought away. "I won't kill Emma!"

"There are loopholes. Always are. We can help you. We have the knowledge and power you need. You've lost too many people you care about because you didn't have the power to save them. Think of Milah. Think of Liam. Think about what you would have done if you had had the power to avenge them."

Killian thought of everyone and everything he had lost but he then thought of Emma and everything he had gained since she had come into his life. He had love. Not just hers but Henry's as well. He had family and friends that he had never expected to find. It was then he realized that the voices had stopped.

He knew exactly where she was and as he pictured her in his mind he was suddenly right in front of her. His heart ached at the sight of her.

"Killian, you're okay!" She exclaimed. "It worked!"

"Swan, I didn't want to see you. You did this to me, to us," he breathed barely above a whisper. "I haven't forgiven you."

This was partly true. He was still mad at her, the Darkness silently fed that feeling in an attempt to push him down the dark path, and he was struggling against it with all his might.

"You can forgive me. The man I love, the good man, is still in there. We have to fight the Darkness. We are more powerful together. You know it. You feel it. Our love is greater than this Darkness and together we will come out of this. You just have to let me in. I love you. And all sins can be forgiven if someone loves you."

She stepped closer to him and when he didn't stop her, she reached for him and he pulled her into his embrace.

"Emma," he said between kisses. "The Darkness recedes when you're right here."

"Killian, stay with me. Please?" Emma whispered into his ear.

Killian felt Emma pressed so closely against him that he couldn't think about letting her go. He closed his eyes and pressed his nose to her neck, kissing a trail from the nape of her neck to her ears. She closed her eyes too, one hand gripping his hair and the other on his jacket, pulling him closer. When they both opened their eyes, they realized that they had transported themselves to the room above Granny's.

Killian looked around the familiar room, a large bed at the center and a wooden chest in front of the bed that contained additional bedding. Opposite the bed was a fireplace with two mismatched armchairs placed in front of it. He had lived in this room for a time when he brought Emma back from New York, until Ursula restored the Jolly Roger to Storybrooke. It felt like home.

"The connection of our magic and our love is stronger when we are together. Can you feel it?"

Killian had felt it as sure as he felt his own heartbeat. As sure as he felt her heart beating in time with his own. They had been forged anew in a terrible way. They were connected in a deeper way than their love already had bound them. When he turned his attention back to his Swan the whispers faded again. Together they could hold it back. Together they could survive this evil.

Middlemist petals lay on the floor and on the bed with candles floating throughout the room.

Emma looked into his bright blue eyes. She thought for a split second about the fact that she had magically hidden Excalibur and she might have accidentally used it on Killian when she asked him to stay with her. She pushed it from her mind and focused on how she felt. How he made her feel with his hook pressed into her back, gently pulling her closer, his hand on waist and his body melding with hers.

"Emma, love," he said pushing his hand into her jacket pushing it down off her shoulder. "What's with all the flowers?"

She had magicked the petals and candles into the room because she had wanted a romantic setting. She pushed away from him and she saw a flash of disappointment in his face. She finished taking off her jacket and sat down on the bed to pull off her boots. She stood back up still wearing her skirt and corset and looked up into his eyes again.

He stood speechless in front of her, his eyes a deeper blue then she had ever seen them.

Emma, are you certain that this is what you want?" Killian's wanted to make sure it was Emma who wanted him, not the Darkness.

"Killian, I love you." She waved her hand and suddenly Killian realized he was only wearing his shirt and breeches. His jacket, vest and shoes were on the floor nearby.

Killian walked up and circled behind her. She gasped as cold steel slipped behind the strings of her corset and they were ripped away with his hook. He pushed her skirt and underwear down to her feet and she gingerly stepped out of them. Still holding her corset to her breast, she let it fall and turned to him. As she turned to him, he touched his hand to her hair and restored her flowing blond tresses, watching them fall down to cover her beautifully pert breasts.

"Killian? I need you."

"Aye, love," was all he could manage to say as he took his shirt and breeches off. He moved to take off his hook as he had done on previous occasions, but she stopped him.

"Don't," she said quietly. "I love all of you."

Gods, she was amazing.

She walked over into his waiting arms. He wrapped his left arm tightly around her waist, cupped her face in his hand pulling her towards him for a kiss. She trailed her fingers down his stomach and lower to his erection. He stopped breathing and broke off their kissing for a moment as she grasped him and began moving her hand up and down the length of him. She gave him a wicked smile and leaned in to devour his lips as her hand continued caressing him.

"Emma... love... you must stop. I .. I can't," he said in short gasps. He waved his hand and they were lying on the bed. Another wave and he had handcuffed her to the headboard.

"Killian, what the hell?" she shouted.

"Think of this as payback, love, for every time you've chained me up. Just relax. I think you'll enjoy this. I've soundproofed the room so feel free to scream if you must," he said raising his eyebrows in the most seductive fashion.

She looked into his eyes and she felt exhilarated. She squirmed but he held her in place as he suckled her breasts, pausing to kiss just under her breasts and continuing kissing down to her navel. She could feel the building of tension in every fiber of her being. As the kisses reached the triangle of blond hair between her legs they stopped. He pushed her legs open using his hook and kissed her inner thighs as he slipped one finger then another into her moist center. Emma was already so wet for him but he was determined to give her as much pleasure as he could.

She went wild and screamed his name as his fingers coaxed her to come.

"Killian, my love, I need more..."

He pushed another finger inside and used his tongue to bring her to the very edge of destruction. He stopped for a moment and watched as Emma bucked up trying to escape but the cuffs and his arm across her stomach made real movement difficult. He pushed a fourth finger inside her and she let out a strangled cry. He covered her with his mouth again, working his fingers and tongue in tandem to bring her pleasure until she finally came crashing around his fingers.

Pulling back his fingers, he undid Emma's magical restraints. He kissed her inner thigh again and she squealed. He moved to position himself at her entrance, but stopped himself. He wanted her so much, but if she asked him to stop he would. Even if it killed him. It felt like weeks, rather than days, since they had lain together in the field of Middlemist and they had no protection then or now. He didn't want her to regret their lovemaking or the consequences that might follow.

"Only if you are sure..."

"Oh, ... please... yes," she said as she drew him into her; small, short gasps escaping her throat until the moment he was fully seated within her. He began moving, his breathing as harsh and uneven as hers. Emma looked him in the eyes as she meet him thrust for thrust. In their lovemaking there was nothing but Emma and Killian. No Darkness. Just love.

"Emma!" he whispered into her ear, his hand on the right ride of her face while shifting his other arm under her back causing her to arch her back.

Killian felt her tighten around him as her body began to orgasm and he pulled back to watch her face. Emma looked at him intently, her green eyes dark with pleasure. He loved this woman so much and didn't know what he had done to deserve someone like her.

"Killian, please do that again. Put your hand on my face and whisper in my ear again," she demanded.

"As you wish, my princess." Killian growled in her left ear as his hand caressed the right side of her face. He slid his fingers into her hair and growled into her ear again, loving that she was so turned on by his voice.

Emma could feel the tension building within her again. The sound of his voice thrilled her to no end. He could make her come by just talking and had done so before today if she was honest with herself; he was always a talker during sex and Emma loved it. She could barely catch her breath. Killian was now whispering into her ear (come on darling, so gorgeous, so wet for me, such a wanton princess aren't you?) as he thrust slowly, pulling back so they were almost separated and thrusting back hard. She screamed each time she felt him push as far as he could.

"You like being fucked like this? Don't you, your highness?" Eyebrows arched, looking her in the eyes. When she didn't immediately answer him, Killian pulled out and teased her entrance with his cock. He moved so that the tip of his cock rubbed against her swollen clit. She screamed.

"Yes! Damn you, pirate! I can't take this anymore!"

Neither could he. He re-positioned himself and thrust back into her. She was soaked and he moved easily within her tight walls. He thrust as hard as he could. He leaned down and slid his fingers into her hair again. She pulled his face to hers, devouring him in a kiss.

"Harder!" she whispered as she pulled away. He snapped his hips faster as she commanded and she matched his pace, moving with abandon. She kept her eyes open, staring into his sea blue eyes. She was drowning in them and she knew she was lost. The fire and emotion there would have been overwhelming as hell to the Old Emma. She would have been ready to bolt. But she was done running; she could never imagine leaving him again.

"Oh, Killian, come with me," she managed in a barely audible sound as she shattered around him. Together.

"Emma!" he groaned. She felt his release pour into her as she convulsed with her orgasm. He kept moving within her until he was utterly spent.

Killian collapsed on Emma briefly before he tried to move. He didn't want to crush her but she held him to her, unwilling to let him go.

They lay entwined for minutes or hours, neither of them knew. Time seemed to pass differently because of their immortality. Emma and Killian clung to each other, showing their love over and over again. As Dark Ones they didn't need sleep, however together in each other's arms, sated and in love, they slept the most peaceful sleep either of them had experienced in ages. A peace they both knew wouldn't last.
