Regina comes to the Dark Swan for answers but what she gets is more than she expected. The revelation of her own denied feelings comes to haunt her as she tries to reach Emma and bring her back from the depths of darkness. But it's very tempting to leave Emma this way, as Regina finds herself constantly aroused by the Dark Swan's tactics. Two corrupted hearts struggle resisting the call of darkness.

Kiss of Doom

The door burst open after a gust of wind, allowing Regina to storm in. A week had passed since the Fury attacked them and Emma had not made any appearances after the incident. Rumor had it Hook had broken up with her, people heard him telling this to his comrade Smee while both men got drunk in a tavern near the docks and had a good time with women you pay a small price for a night of magic. Yes, Storybrooke had its own clandestine brothel; Regina had found it suited to carry it all the way from the Enchanted Forest. It was a needed "evil" for some (or many), and who was she to judge? She didn't think much of it, really. To her it was just an adult recreational park.

"Swan! Where the hell are you?" Regina called for her.

It was the third time this week she'd come to 710 on Mifflin Street only to find an empty house. One would think the Dark Swan would be careful enough to leave her door locked with a blood spell, but she never did. Mere mortals wouldn't dare come near, but Regina would, so it was almost like an invitation for her to do.

"Do what you're so skilled at and make yourself at home, Regina."

Emma's voice came from everywhere and nowhere at the same time, Regina couldn't see her. She sounded tired but there was still the edge of danger in her tone.

Regina remembered she had said the same exact words to Emma before, the day she planned to send her away from Storybrooke with a little something for the road, spiced-up with a sleeping curse, almost three years ago.

"So you are home. Then why don't you show up, Dark Swan ?"

Regina marked the title so she would taunt Emma and make her come out, but still there was no sight of her. She paced in the foyer as she grew more impatient, and as she did so, her eye caught notice of the strange wooden door under the staircase.

Where could that possibly lead to? She had to investigate.

"Or are you suddenly afraid of the Evil Queen?" Regina taunted again.

She walked toward the mysterious door then, but in a flourish of black smoke Emma appeared to her, stopping her dead on her track just before her hand made it to the knob.

"Ha! Please," Emma let out a throaty laugh, "we both know the only one afraid here is the Savior wannabe," Emma responded mockingly. "Just accept it. You're a fraud," there was a special bite to Emma's last line, laced with disappointment. And... Sadness?

Regina felt at fault, but she had no idea of why, no memory of the reason behind this feeling of guilt. It couldn't just be because she was forcing herself to become a Savior and borrow Emma's hard-earned title.

Regina swallowed nervously as she locked eyes with Emma's cold stare, looking for answers she knew she wouldn't be getting. At least not easily, not without a fight. With Emma it was always play tug of war.

She found her voice again, "If I'm so afraid of you then why am I here?" She tried to be challenging, it was at what they both excelled.

"I don't know, Regina, why don't you tell me? You're the trespasser," she smiled sarcastically.

"I don't have time for games, Miss Swan," Regina rolled her eyes. And that was like if Regina had just pulled the plug.

"Games? I'm not playing with you," Emma took a step forward, daringly. "Yet."

Regina felt intimidated, took a nervous step back but the Dark One took yet another further, getting closer to her again, and continued cornering her until she was driving Regina back to the door from where she'd entered and now they were so close Regina could feel the heat radiating from Emma's body impossibly angry.

"Tell me why have you come here, was it just to taunt me? ME, the Dark One?" Emma brought her face just few inches from Regina's. "Are you so inclined on dying you must jump at every opportunity? You're no Savior: you don't value life, Regina, only when it suits you.So, tell me, what else do you want from me that I haven't given you already? Was your Happy Ending not enough?" she snarled.

Emma's voice was dark, loud; her words: sharper than the dagger that commanded her. Emma continued to make Regina feel responsible of something she had no way of remembering.

Regina heard the door slam shut behind her, startling her more, and when she turned again Emma's face was now just an inch from her own, eyes dark with rage, but also something more as they glanced down at her lips for a second that lasted too long.

"Emma…" Regina whispered.

Her body was shaking, her mind was spinning; she felt she would faint from the impression, but stood her ground. Everything was going too fast for her to make any sense.

"Why are you saying this? Whatever I did to you in Camelot, please tell me! I need to know so I can do right by you. I want to keep my word and save you."

Regina could see Emma's vein pulsing in her temple, like a ticking bomb about to explode any moment and she would be the only victim it would be taking down with her. Then, silence.

Emma leaned down and almost nestled her face in the curve between neck and shoulder, closed her eyes, inhaled deeply, taking in Regina's sweet smell, and let it out in a heavy sigh that was more unnerving than it was relieving. She pulled back from nearly touching with Regina's skin and opened her eyes slowly to study Regina's lips once more.

Regina's heart was pounding so hard inside her chest she thought Emma might be able to hear it. She was so scared of this Emma, but at the same time she couldn't help but feel this magnetic pull toward her that made her crave to feel her closer. Much closer.

"There's nothing left to save; this is who I am now."

Heat turned into coldness and momentarily Regina was sure she had just seen Emma, broken-hearted, and she couldn't stop herself from trying to reach her again, so she took the last step that kept them separated. Nervous hands glided over the warm wool of Emma's trenchcoat to rest on her back, chin coming to lay on Emma's shoulder as Regina tentatively- insecurely, held onto the Dark Swan's body in an awkward embrace. Their very first, and quite possibly the last hug.

"You're right," Regina said softly, holding onto Emma's body even though she was not returning the hug. "Emma, I—"

Emma's body stiffened as Regina held her closely. She pretended to be unaffected by the hug she never saw coming, but for which she'd been yearning since the first time she laid eyes on the Mayor. But that was her secret; a secret she swore would be buried in Camelot forever with their memories, and now it was back to haunt her, just as was the reach of light.

"You have to go..." Emma's voice came out weakly.

"Emma, please," Regina pleaded.

"Leave before you say something you'll regret later!" Emma raised her voice and pushed her away. "GO! Just, go!"

"Emma, stop! Why do want to make me run away from you? What happened to us in Camelot?"

"Us?" Emma's darkness returned. "You sure you want to know what happened, how it happened, where it happened?" Emma grabbed her by the wrist and pulled her close, body flush against hers.

Regina felt a mix of fear as well as excitement with Emma holding her more intimately but oh so dangerously. Part of her wanted to stay this way forever; the other to vanish before it was too late—perhaps it was already. This could be her doomsday.

"Let me show you," Emma whispered in her ear, voice mellow, but you shouldn't let it fool you.

Black smoke engulfed them and after dissipating Regina found they were underground, in her very own vault.

"Emma, why have you brought me he—"

Regina was shut by Emma's lips crashing on hers, and oomphed into the kiss when her back hit cold stone as Emma pushed her against a wall, lips still locked, tongue demanding entrance to her mouth, which she didn't deny, against her better judgment.

Was this really happening or was she dreaming?

No matter, it was just as chilling as it was arousing and Regina had always found herself drawn into loving someone forbidden.

But this wasn't Emma; it was the Darkness, and Regina pushed her away and gasped for air.

"What the hell do you think you're doing?!"

"Showing you," the Dark Swan responded casually. And claimed her again, this time burying her face in her neck, giving as much pleasure as there was pain in every kiss, every bite.

Regina felt her strength leave her arms, her knees, as she tried to fight off Emma but not really; hers were effortless attempts at ridding herself of the Darkness having a taste at her, she was letting it feast on her.

"Emma…" Regina groaned, throwing her head back to expose her throat for her Savior — the Dark One — to devour with her kisses.

Regina's fingers got tangled in tresses of white, silky hair that had come loose from Emma's now undone bun as Emma moved down to kiss the valley between Regina's breasts, nicely exposed by the pronounced v neck of the black lace camisole under her red blazer.

Emma had her just where she wanted; at a point of no return where Regina could only want more. She just needed to make sure, so she snaked a hand down Regina's torso, feeling how her muscles contracted at her touch, how Regina's breath became much more ragged, and felt with her bare hand the humidity from Regina's arousal through the fabric layers.

"Em-ma," Regina was now moaning her name and it was music in Emma's ears, but she was not about to give into Regina's power over her. No, not again. Not ever. It was Regina who had to break this time.

Emma's hand rubbed against Regina's sex through the fabric, but when Regina sought her lips to kiss her again, Emma pulled her head back and looked her in the eye, coldly.

"If only I had been your soulmate," she told her as she retrieved her hand from between her legs.

Regina looked with shock and disbelief at her. Emma sneered and had malice in her eyes.

"I would have given you this happy ending. So to your question: this is a clue of what you did to me," Emma told her before vanishing, voice quavering momentarily.

Regina was speechless. She felt frustrated that she had been so riled up only to be left unsatisfied and dumbfounded.

Had she really done this to Emma back in Camelot?

Had she used her?

Regina had had her share of wet dreams with Emma when she first came to town, but she never acted on her impulses. But whatever happened in Camelot, stayed in Camelot and she urgently needed to remember.
