Chapter 4

The kiss starts slow and tentative, both of them testing the waters with each other. Common sense and propriety are thrown away to the wind, what matters is what's happening right now. Emma pulls Killian closer by his lapels, his hand tangled with the hair at the base of her neck and the other one cupping her cheek. Emma doesn't know who starts it but suddenly the kiss gets desperate and hungry, teeth gnashing with each other's, both of them moaning into each other's mouths. Emma swears she'll die the second he bites down on her lower lip and tugs on it, grinning at her drunkenly when he does it.

Emma needs things to move faster, she hasn't felt this wanted in ages. She places her hand on his thigh and runs it up and down softly, loving the fact that when she reaches around his zipper she can tell just how bad he wants her too. With every second that his lips are on hers, Emma feels like she's waking up from an eternal sleep she didn't even know she was in. Every part of her skin feels like its on fire, she wants more. She needs more.

"Emma…"he groans as she starts to trail kisses along his jaw.

"Mmhmm?" she mumbles back to him, reaching his earlobe and nibbling at it.

"I want you." He says darkly, his voice dripping with lust. She meets his eyes and tries desperately to focus her surroundings and she expects he's doing the same.

"So have me." She says, a mischievous smile tugging at her lips.

Emma feels like she travelled across the reception area in two seconds, she spent most of the time trying to regain her composure. You are not drunk, she thinks, just glide and no one will be able to tell. Many of the guests had gone but there were still a few stragglers. She didn't remember seeing Mary Margaret or David, so she must have missed their grand exit. She told Killian she'd meet him in his room, but part of her wishes she had just walked to the room with him that way she would have someone to help her keep her balance. She almost fell up the stairs, she really does not remember the last time she was this drunk. Once she reaches his room she goes to give a light knock on the door but Killian opens it almost at the same time her knuckles reach the wood. She stumbles a little on the way in but he steadies her.

Still grabbing her by her upper arms, he gives her a blazing look and immediately kisses her again. Her arms quickly wrap themselves around his neck and she moans into his mouth. Heat is radiating from her stomach again, filling every inch of her with desire. Killian's hands find the zipper on the back of her dress and quickly undo it, making her dress fall to the floor in a pool around her ankles.

"You've got goose bumps, Swan. Are you sure you want this?" His hot breath is tickling her ear and the last thing Emma wants is for his hands to be anywhere but on her. His touch makes her feel wanted.

He's making her feel alive.

"Shut up and kiss me." She says pulling him back to kiss her by his collar. He grins into the kiss and she grins back into it. Her hands are fumbling with his shirt buttons but finally it's off, exposing his chest. He hisses as she lightly drags her nails down his chest and stomach. She smiles up at him and places her lips on the side of his neck.

Hands still on his chest, Emma pushes Killian back until the back of his knees touch the bed and he lets himself fall on top of it. Everything starts happening then, whatever is left of their clothing is off and strewn across the room in seconds. Killian has pulled her with him in bed and is kissing every inch of her exposed skin. He starts at her lips and makes his way down, kissing her neck and sucking on her collarbone. Emma's breath hitches when his lips make way over her exposed breasts. His warm mouth feels wonderful and when he bites down on her nipple Emma lets out a moan that makes Killian look up at her and chuckle, clearly proud of his work. He continues trailing kisses down her body, grinning before kissing her hipbone. Emma starts squirming instantly, her ticklish spot reacting to him just like it used to eight years ago. She starts to beg him not to kiss her there and tries to move out his head off but he takes her hands and pins them to the side, keeping at it.

"Killian, please." She breathes, a ghost of a laugh on her face.

"What do you want, Swan? Tell me what you want." His eyes are dark, full of lust. He's kneeling on top of her, swaying slightly, just as drunk and mesmerized as she is.

"You."

That was all he needed. In a second Killian parted her legs and slid inside her. Emma felt the familiar fullness take over her. If she thought her body was waking up to his touch earlier, it's definitely awake now. Killian stays still for a few seconds, savoring the moment just as much as she is, then he starts to move. And boy, does he move. He takes her legs and props them up, making her hug his torso with them. He's moving so deep inside her, making her feel fantastic. He tells her to kiss him, and she complies relishing in the feeling of being so incredibly wanted. She feels herself being close to the edge, her orgasm right there practically in her grasp. She reaches down in the spot between them and helps herself get there faster, her fingers having reached her clit, the pressure making her want to scream out. Killian smiles down at her and tells her how sexy that is. They are so connected, it's as if the last eight years hadn't happened. She's close now, so close.

Fuck, fuck, fuck.

And suddenly, sweet release. She feels her orgasm all throughout her entire body. She pulls Killian closer and drags her nails on his back. Her orgasm was enough to bring him to his edge. He thrusts one more time, two more times, her name a prayer on his lips, and finally, with a moan, he stills on top of her.

Killian rolls off of her and lies on his back, beads of sweat on his forehead. He mumbles something about it being incredible and takes her hand in his and presses his lips to the back of it. Emma has been in a daze since she came, eyes heavy and the world fogging up all around her. Inebriation, exhaustion, and bliss take their toll on her, dragging her to sleep.

The sun shines brightly the next morning, rays hitting Emma square in the face. Her eyelids flutter open and she's met with an excruciatingly painful headache, a room that's not her own, and an arm draped across her bare stomach.

Oh, no.

Emma is terrified of turning sideways and facing the mistake she made last night. She doesn't even remember anything after sitting in the dock with Killian.

Please God, no.

Emma finally resolves to turn around and finds her worst fears confirmed. There is no doubt in her mind that she had sex with Killian, that she was unfaithful.

She gives a frightful yelp.

"Oh, my God. Oh, my God! What did I do?" Killian opens his eyes and sees Emma covering her face with the sheet, almost willing herself to believe that if she couldn't see it, it didn't happen.

Killian's eyes open wide. It's nice to know that she's not the only one with little recollection of last night.

"We didn't." he says, clearly just as shocked as she is.

"We must've. I don't know about you but I'm completely naked, Killian." He lifts his side of the sheet and takes a peek underneath it.

"Aye, we did." He resolves, letting his head drop back into the feather pillow in disbelief.

"I have to go. This didn't happen." Suddenly Emma springs off the bed, using the sheet to cover herself up before looking for her items of her clothing thrown everywhere around the room.

"No, Emma! Please stay. It happened…for a reason, love." Killian is much less modest. He gets off the bed in all his buff glory and slips on some boxers and starts walking to her.

"Don't call me that! This was a drunken mistake and it didn't mean anything." She says as she angrily snatches her bra off his hands and slips it on.

"Emma, you can't just walk away from this." He tells her while he slips on a dark t-shirt and buttons up his jeans.

"Watch me." She retorts defiantly, shimmying back into her dress.

"Emma, please. Be reasonable." He pleads.

"I am being reasonable, Killian. I'm married. I was weak last night, you said all the right things and I fell right into it. I'm not saying I'm not at fault. I made a mistake and I admit it. Now, I'd like to forget about this whole thing. Okay?" Emma just wants to get out of this room as fast as she possibly can. Ever the runner and the avoider, she wants to put this entire disaster out of her mind. Out of sight, out of mind.

"As you wish." He mumbles, before she heads out of his room, closing the door loudly.

Emma quickly arrives at her room without being seen and locks the door behind her. Two seconds later she plops down on the floor and hugs her knees closer to her, her face buried in them. Why did she do that? Why? Why did she have to sleep with Killian of all people?

She sighs and wishes she didn't feel like her life was spiraling out of control. Was she going to confess what she did to Walsh? Was she going to feel okay with keeping it a secret from him and go on with life as if nothing ever happened? Was she going to see Killian again? And if she did, was she going to be able to resist any and every temptation and give friendship a chance? All these questions keep running through her mind on repeat as she takes a shower, as she gets dressed, and as she heads down to meet the Charming's' for brunch before heading back to New York.

She's late and met by a glowing Mary Margaret and David, the ever sophisticated Eva and Leopold, and Killian. Of course, the only seat left is right in front of him.

"Did you two have a nice night last night?" Mary Margaret asks brightly.

"What? Why?" Emma responds a bit too harshly and a bit too flustered.

"Because it was our wedding?" Sipping on what's left of her mimosa, Mary Margaret laughs and shakes her head at her.

"Oh, yeah." Emma bites her lips, hoping she didn't give anything away.

"I'm afraid Swan and I are still recovering from last night's bar service." They laugh while Killian continues to charm them. Emma knows she should feel thankful for Killian saving her like that, but instead she decides to sulk lower in her seat. He looks at her and gives her a small smile, testing the waters. She looks away disinterested, pretending that his smile didn't cause a familiar heat to start radiating from her stomach.

Around three-thirty in the afternoon, Emma is finally on her way back to New York. Killian has been courteous enough to not sit next to her, giving her the space she had previously asked for. She's been listening to music the entire ride, anything to keep her from thinking about the memories that were resurfacing from last night. She didn't want to remember how amazing his kisses were, how he pinned her arms above her head and moved inside of her. She stole so many glances during the trip and he even met her gaze a couple of times.

When the train starts slowing down she sees Killian make his way towards her. He raises his hand up to stop her as she frantically starts shaking her head at him.

Do not come over. I do not want to talk to you. Emma averts her gaze and looks towards the window.

"Swan, stop. Now, you do not have to talk to me but at least look at me." He says, his voice strong, commanding attention.

Emma doesn't say anything and just looks at him.

"I just wanted to tell you, about last night. I do not regret it. Not one bit. Now, I know that you never want to talk about it again and I understand. But I know, that deep down, you don't regret it either and you owe it to yourself to be happy."

By that time the train had stopped and they had arrived at New York. Killian turned away from her and exited the train while she sat in a stunned silence. On her way home, Emma's mind raced a mile a minute and deep down she knew that Killian was right. All questions aside, Emma did not regret last night at all.
