A New Tradition

"Come on, love! We'll be late for your parents' infernal dinner!"

Emma smiled to herself in the mirror as she gave herself one final once over before heading downstairs. She'd given Killian that excuse days ago after her carefully laid Halloween plans had gotten thrown out the window by some of the Merry Men getting into a bar fight with Leroy and the dwarves on the actual day. She'd made all the arrangements—even gotten Regina to take Henry for the weekend, much to the Queen's delight—then her job had to get in the way. Again.

But she was going to get this moment with her pirate, damn it. Even if it killed her.

Okay, that was an exaggeration. But she needed him. And had this burning desire to see those gorgeous blue eyes pop out of his head at the costume she'd found.

"I'll be right down!" she yelled, picking up the stethoscope off the vanity and wrapping it around her neck. She owed Ruby big time for this. Emma rechecked the pins in her hair and smoothed her hands over the soft white material. Now or never.

She opened the door and gripped the railing for balance as her heels clacked on the wooden floors. Killian's back was to her, idly fiddling with his hook and muttering to himself. Probably something about having to endure an evening of her parents' cooing over her baby brother. Killian adored little Neal, but even Emma had to admit they went overboard sometimes. Fortunately for him, she had a much more enjoyable evening planned.

Killian sighed and started to turn at her approach. "I received a message from Henry, he is safely with the Qu..." His voice trailed off in mid word as his eyes lit upon her. Killian blinked dumbly, mouth opening and closing in shock. "Love?"

"Yeah?" She tried not to fidget under his scrutiny, feeling a bit self conscious in her tight, tiny nurse's uniform. She'd dressed provocatively in her past as a bailbondsperson, but she'd never done anything like this with Killian before. Or anyone, really. There was a tiny doubt niggling her mind that he would laugh at her.

"We're not expected at your parents', are we?"

Emma should have had more faith in his perceptiveness. She felt herself relax, a slow grin curving her red lips. "How did you know?"

Killian's gaze seared her from head to toe, those blue eyes darkening. "Because there was no way in the many, many realms I was letting you leave dressed like that."

Emma took a step toward him, putting a little extra sway in her hips, just because. "And what's wrong with the way I'm dressed?"

"Absolutely nothing. But that delectable body of yours is mine."

Emma had to suppress a shiver at that, the way he said mine doing wicked things to her. She'd never admit it, but she loved that possessive tone he sometimes used when they were alone. It was nice to have someone whose sole focus was her.

Emma reached out and curled her fingers around the charms of his necklace, tugging him closer until their breath mingled. "And yours is mine," she said, her voice low and seductive. "I think I should give you a through examination."

Killian smirked back at her, tongue darting out to wet his lips. "By all means, Swan."

Emma brushed the tip of her nose over his, inhaling the strong scent of salt and Killian before bringing her lips to his. He opened for her instantly, a deep moan rumbling in his chest. The sound went straight to her core, walls clenching involuntarily. It didn't matter how or when or where; the passion and desire she felt for him ran bone deep. Indeed, almost from the very beginning, back when it scared the shit out of her. Now she just craved it, craved him, knowing he would never leave her unsatisfied.

Killian's good hand and hook slid over her spine until he cupped her ass, squeezing through the thin cotton, hauling her body firmly against his. Emma rubbed herself against him shamelessly, breasts flattened into his chest, aching to be touched.

"Emma," Killian breathed, his lips sliding down her throat, nipping at her pulse.

"Oh god." She knew she was supposed to be doing something, but she couldn't remember what. All she could focus on was his hard body pressing into hers. "God, I missed you."

"And I you, my love." He backed them up to the huge armchair and collapsed into to it, pulling Emma down to straddle his lap. "Where did you find this?" he asked, his hand tracing the curves of her body, nose nudging her cleavage.

"Store...for Halloween," Emma replied, biting her lip. "I wanted to surprise you."

Killian undid the top button of her uniform with his teeth. "Well, you succeeded, if a few days late." His tongue licked at the swell of her breasts; Emma moaned. "You taste divine."

A flood of heat rushed through her; her clit throbbed. She ground her hips down, muttering in relief when she felt the thick ridge of his cock press against her aching core. "Are you gonna help me out of it or tease me all night?"

"I thought you were supposed to examine me, darling," Killian shot back, hips thrusting up suddenly. "But if you'd rather I just fuck you..." He unbuttoned two more buttons until she was practically spilling out of her top, his tongue and lips latching onto a hard peak and suckling fervently. His hook slid over her bare thigh, catching the hem of her skirt and pulling it up until it was loose around her waist, exposing her white panties.

Emma arched her back, one hand braced on Killian's knee as she rubbed herself over his arousal. The seam of his pants rubbed against her just right, her clit hard and aching, release coiling tighter and tighter in her gut, unintelligible sounds tumbling from her lips.

"That's it, love," Killian said, his hand ripping her top to expose her other breast. "Get yourself off for me." He worked her nipples with his hand and mouth, sending her higher and higher until her body exploded in bliss. Emma cried out, eyes squeezed shut, her body rocking in his hold. He held her until she calmed, slumping against his chest.

Killian kissed her sweaty brow and held her close, allowing her to recover. "I love watching you," he mumbled against her skin. "You are so beautiful, love."

Emma felt her heart stutter in her chest; this was what she loved the most about him. His pure love and devotion to her, always seeing to her happiness ahead of his own. He was unlike anyone she'd ever known and she loved him so much it hurt.

Gently, she pressed a kiss to his neck, his scruff tickling her nose. She moved higher, just lightly kissing and nibbling on his skin, knowing he was still unsatisfied. And she wanted so much more than just dry humping him in the big chair. She wanted him to fill her, to stretch her, to brand her as his. She smiled when she heard the low rumble in his chest, her ministrations having the desired effect.

"I'm going to take off your clothes now," she whispered in his ear. She felt him shudder under her, his breathing hitching. "Just let me touch you." Killian nodded silently, desire drowning his eyes. Emma smiled and pressed a kiss to his lips, sucking on his bottom lip as she started to undress him. She had to scramble out of his lap to pull his waistcoat and shirt free, tossing them to the floor.

Emma ran her hands over the bare skin of his torso, relishing the feel of the muscles tensing and flexing under her touch. He had surprising few scars marring his skin, but she leaned between his spread legs to run her tongue over each one. Killian's hand fell to her hair, fingers pulling on the pins until the blonde tresses tumbled down her back. He always liked her hair down, so he could toy with it.

"Gods, that feels incredible," he said softly. Emma smiled, pleased. It wasn't often that she just got to explore his body; he was usually focused completely on her. Emma ran her fingers over his chest hair, and her nipples tightened in response. She loved the way it felt to have it tease her as they moved together.

"Your heart's racing," Emma said, kissing the skin above it. "I can feel it."

"Only for you," Killian replied, eyes falling closed. "Always for you."

"Would you like to hear it?" Emma asked, getting an idea.

Killian looked at her quizzically. "I'm not following you, love."

Emma's hand fingered the stethoscope that still lay around her neck. How it had managed to stay in place, she didn't know, but she was grateful it had. "With this." She placed one last kiss to his skin and climbed back into his lap. She put the ends in her ears and took the round metal and placed it over his heart.

Killian flinched a little. "Bloody hell, that's cold!"

Emma rolled her eyes. "So's this," she reminded him, tapping his hook with her finger. "I let you touch me with that."

Killian's eyes darkened again. "You love when I touch you with that," he said knowingly. "Very naughty princess you are."

Emma leaned down and kissed him again. There was no sense in denying that. She was dating a pirate for heaven's sake. "Hold that thought, okay?" Killian nodded, still wondering what she was up to. She pressed the metal to his chest again and heard his heartbeat plain as day in her ears. It was strong and a little rapid from their play. She loved that sound.

"Here, you try." Emma took the stethoscope out of her ears and placed it in his, positioning the metal over his heart again. "Do you hear it?"

Killian's eyes widened in wonder. "Aye." He listened for only a few more seconds before turning back to her. "May I hear yours?"

He said it with such reverence, Emma thought she would melt on the spot. "Okay." She lifted the round piece of metal to her own chest, settling it over her heart. She tried again not to fidget, Killian's intense stare almost too much. "What?" she said at last.

"It's so strong," Killian said in awe. "Just like you."

Tears pricked at her eyes, as her emotions threatened to overwhelm her. If her heart was strong then it was because of him. He'd fought for her, loved her, helped heal the painful shards of her heart back into a working whole. She truly didn't know who she'd be without him.

"Kiss me," she demanded, before she lost it completely.

Killian growled and complied, pulling her down for a searing kiss. Emma's toes curled as he kissed her deeply, exploring every inch of her mouth. The stethoscope impeded them, so Emma unhooked it and tossed it to the floor with a soft thunk of metal hitting wood. Killian's arms came around her, pulling her flush against his body. But she was still wearing the remains of her costume. She wanted them naked. Right now.

"Couch," she gasped, fingers diving in his hair. She pulled him to her breasts, ignoring her request so she could have his mouth on her again. He obliged her, moaning when she pushed them together so he could suckle both with a tiny turn of his head.

"You like this, don't you?" he asked, burying his face in her cleavage, mouth driving her crazy.

Wave after wave of want washed through her, settling deep inside her, leaving her aching. "Oh god, yes," she said, not wanting him to stop, but wanting more.

As if he could sense her conflict, he nodded. "Soon, love," he assured her, nipping at the underside of her breast. "I'll have you very soon." Heeding her earlier demand, he picked her up and carried her to the nearby couch, where he tore through the remnants of her costume. Emma watched hungrily as he deftly removed his pants and boots, leaving him naked before her. His thick cock bobbed proudly against his stomach and Emma's mouth watered, the ache inside her almost painful. "Spread your legs, darling."

Emma did as he asked, exposing her soaked skin to his sight. She shivered as the cool metal of his hook slid along the inside of her thigh. "Oh fuck," she whimpered, fingers gripping the edges of the couch. He was going to tease her again, rub the metal over her heated core until she came.

Killian chuckled. "Such a wanton thing," he murmured. "The princess craving the pirate's hook." Emma hissed when the metal finally reached where she needed him, her hips rolling into it automatically. "Don't stop."

"As you wish." He alternated his strokes, her arousal coating the metal, slipping over her sensitive skin. She didn't know why the hook was such a turn on for her, but she loved it. Killian slid two fingers inside her as his hook teased her clit mercilessly. "Come for me, Emma. Let me see what I do to you."

"Fuck!" Emma yelled as her second orgasm made her shudder. She clawed at the couch as Killian worked her, drawing it out until she was breathless. But it still wasn't enough. She'd hardly come down from that high before she was pulling at him. "I need you in me. Please."

Killian growled and nodded. He spread her wide before easing himself into her, teeth gritted as he fought for control. "Fuck, you are so tight, love." They moaned in unison once he was completely sheathed inside her, the stretch and burn of him along her walls what she had been craving. Before she met him, sex was just something she did when the itch arose; now she was addicted to it, to him and how being with him made her feel.

"Oh god, move," Emma pleaded. "I need you."

Killian lowered his head and captured her lips in a passionate kiss as he heeded her plea, hips pistoning into her roughly, his cock hitting her deep. Emma cried out in pleasure as Killian gave her exactly what she wanted. This was who they were, rough around the edges but with a deep connection that could weather any storm. The savior and the pirate bound together in love and passion. She could feel it with every stroke, their feelings for each other making them whole as they sought release. They fell over the edge together, their desperate cries filling the air, bodies trembling in each other's arms.

Killian collapsed on top of her, head buried in the crook of her neck. He was breathing hard, but Emma swore she heard him say "I love you" over and over again. She used what little strength she had left to cradle him against her, holding him close despite his weight.

"I love you, too," she murmured softly, stroking his back. "I love you, Killian."

That seemed to bring him back to her. "Sorry, love," he grumbled, starting to push himself up.

"I don't mind."

He thumbed her cheek. "I mind."

Emma kissed his palm. "You're an idiot."

"Gentleman, my love."

"Pirate," she countered.

"Your pirate."

"Yeah, you are."

Killian glanced away, then back. "We should get you to bed."

"Believe it or not, I had intended us to do this in the bed."

Killian smirked. "You were just too irresistible to wait."

Emma moved to sit up, curling into Killian's side. "So you liked your surprise?"

"Aye. Is that a...common custom for this holiday?"

Emma felt herself flush. "No. I mean, yeah. I mean, the dressing up part." Dear god, she was rambling. "The adult costumes tend to be a bit more risque than the kids."

"So I noticed."

"I wanted to actually do this on Halloween, but I got sidetracked."

"That happens often around here, love. I daresay I'm getting used to it."

Emma looked up at him, a smile on her face. No matter what she could trust that he would be there, right beside her. "Maybe next year we'll plan better?"

He looked down at her with a curious brow. "Are you intending to make this a tradition, Swan?"

She shrugged. "Do you want it to be a tradition?"

He smiled her favorite smile, the one that made her want to kiss him senseless. "Perhaps I could dress up for you next year."

Emma grinned. "I'd like that."
