Part 1 – Let It Snow!

"Why are we doing this again?"

"My God, Sam… you're worse than a five year-old." Donna rolled her eyes at her whining husband. "We're doing this, because it's my first time in New York and I want to see it. And no, not only from the balcony…" She quickly added, noticing that he was about to interrupt her. He just smiled at her being always so quick, almost like reading his mind.

"Besides… I was getting kinda bored you know…" She sighed, peering at him from the corner of her eyes, waiting for his reaction.

"Ooooh… I take it I'm not entertaining enough for the Mrs.?"

"Well, it'd be much more fun with the girls around, that's for sure." She went along with the game.

"It's always much more fun with the girls!" Sam answered on a high-pitched voice, letting out a girly sigh. Donna couldn't help, but giggle and shake her head at him, as she pulled him closer to her by their linked arms. Sam just loved to hear his wife's giggle and contagious laugh, and he was determined to do whatever it took to crack her up as often as he could.

"Aaaww. You miss 'em too, sweetheart?" Donna stopped walking and turned to face her husband. "Come here then." He smiled at her as he felt the soft fabric of her glove on his face, and leant down to kiss her. As he was about to straighten up after their quick peck, Donna took him by surprise with standing on the tip of her toes, and brushing their lips together again. "Not so fast babe." She said against his lips, pulling him back down, before sliding her tongue sensually into his mouth. Sam wrapped his arms around her waist, holding her closer to him while their kissing turned more passionate.

"Hey, hey, hey, hey! Ever heard of public indecency? It's a park, there are children around here!" The loud voice and clapping made them broke the kiss, as both of them turned to the direction of the shouting woman. Before Donna could've said or done anything, the petite brunette along with a taller man began to laugh hysterically. She was about to give them a piece of her mind, when she realized that Sam was laughing with them, shaking his head.

"My God, Carmichael… You should've seen your face honey! It was priceless!" The brown-haired woman said trying to control her giggles as she slowly approached the couple with her also laughing company. "But you deserved it, for not inviting me on your wedding!" She added pouting childishly, now standing in front of the pair.

"You do know, that even my sons weren't there, don't you?" Sam replied raising a brow and smirking, as he took one step towards the shorter woman, and hugged her.

"Spare me the details Samantha, I wasn't there, and you'll have to find a way to make me forgive you for that." She answered now breaking from their hug.

Donna raised her brows with amusement as she heard her husband being called 'Samantha' by the shorter brunette, who was so familiar to her. She could swear she'd seen her somewhere before, but where? As Sam was about to introduce them to each other, the dark-haired woman quickly brushed a loose strand of hair from her face, before holding out her hand to Donna. She looked up smiling straight into Donna's eyes, and in the very second their gazes locked a sudden realization instantly hit Donna. Oh…Oh my God! It can't be her. But she looks exactly like…

"…Audrey?" She involuntarily said it out loud, simultaneously with Sam's introduction, so she couldn't catch the woman's name.

"Oh, I'm sorry! You looked so familiar I couldn't help, but…"

"It's okay honey. Remembering faces, and names isn't my strength either, right Poodle?" The woman turned smiling to the guy who was standing now by her left side; their arms linked, mirroring the married couple's stand.

"Karen, this is Donna, my wife you've heard so much about; darling, this is Karen Walker, a very good friend of mine." Sam introduced the two women to each other.

"But you can call me 'Sexy' if that's easier for you." Karen winked at Donna, shaking her hand. "It's nice to finally meet the mysterious love of our gorgeous architect. You were right about her honey, she really is beautiful." She said to Sam, before turning back to Donna.

"And this is my…Jackie."

"Nice to meet you Donna." Jack took Donna's hand, and shook it lightly. "P.s.: Loving the coat Missy. Having a little Marc Jacobs I believe?" He asked, observing Donna's beautiful, white winter coat for a moment, and letting her hand go, he narrowed his eyes. "Yeah, I'm pretty sure it is." He answered his own question, and much to Donna's surprise, he was actually right.

"He's good, isn't he?" Karen asked proudly, noticing Donna's stunned expression.

"Yes, it's very impressive. Are you working in the fashion industry Jack?"

"Aww, you're so sweet! But no, I'm not. I'm an actor."

"You mean actress, Tinkerbell." Karen 'corrected' him with a giggle, and pulling him down to her level, she pecked his lips lovingly.

"So Karen, what brought you to Central Park, when it's snowing out here?" Sam asked smiling, knowing she wasn't really the outdoorsy-type.

"Now that's the million dollar question. All I wanted was, to drink a nice lunch, have a little shopping, and I found myself here. I must have been loaded, because I don't know how on Earth did I get here."

"Don't be so bitchy Kare, it's gorgeous… Look!" Jack said completely mesmerized by the slow rhythm of the falling snowflakes, watching how they swayed in the air wide eyed, like a little kid.

"Yeah, yeah, whatever. So. Are you two ladies up to join us for lunch?" Karen asked cheerfully. "Because it's a little nippy out here, and this baby is empty already." She pulled out a flask of her pocket, shaking it lightly. Unbelievable. Donna thought to herself, smiling. Not only did she look like Audrey, she acted like her too.

"I'd love to!" She replied enthusiastically, looking up at Sam to see if it's okay for him too. He smiled back at her, and leant down to kiss her cheek.

oOo

"Are you fucking kidding me with this?"

"No." Chuckled Sam, seeing Karen's disgusted face as he finished talking.

"Okay, I'm gonna need another drink, and fast." Karen said, grabbing her martini. As she downed what was left of her fourth drink, she motioned with the now empty glass towards a passing waiter, ordering another one.

"God, this is so romantic… like… a fairy tale." Jack sighed with dreamy eyes, leaning on his elbow on the table, propping up his head.

"Exactly. Makes me wanna throw up. Oh, thank you Waiter now that was quick. Someone's gonna get a big tip, huh? Just keep the pace up." Karen said, and immediately took a sip of her fifth martini, as the waiter placed it in front of her. Donna watched the conversation between her husband and the two New Yorkers with amusement. She enjoyed the edgy, teasing atmosphere of it; it reminded her of being with her best friends. And also the times, spent with Audrey…

"Listen to me Donna. If you go to a party… never mind. Anywhere you are, and someone asks you how you got married... do yourself a favor honey, and lie." Karen said, making both Donna and Sam laugh with the serious tone she used.

"Really honey. You don't want to be laughed at."

"I'll keep that in mind." Donna raised her glass to her, as Karen then carried on.

"But ignoring the ridiculous back story, congratulations Carmichael. Looks like you've made it this time." Karen toasted them, and they clinked glasses. Sam placed a quick kiss on Donna's lips before taking a sip of his drink. As he put the glass back down, he felt his cell vibrating in his pocket. Peering down at the caller ID, he stood up from the table.

"Sorry, I have to take this. I'll be right back." He excused himself, and walked out to the bar. Donna, Karen and Jack were all watching him go, checking out his ass. As Donna noticed the admiring looks her husband's behind got, she just smirked to herself, and asked the duo.

"He's got it, right girls?" She bit her lower lip as Karen turned to face her.

"Tell me he's as good as I think he is…" She smirked back at Donna, swirling her martini slowly with the stir stick in it.

"…better."

"I knew it." Karen replied, and then gently shaking off a few drops of martini of the olive, she lifted it to her mouth. With one simple move, she took it between her teeth and expertly pulled it off of the stick. Donna found herself staring at her lips, and snapping out of it, she looked into her dark-brown eyes, only to see, that she'd been caught. Karen's lips now curled up into a naughty smirk as she swallowed and took a sip of her drink.

"Okay, you two stop it right now, before getting into the details of hetero sex. Eww!" Jack grimaced at the thought. "Tell me about the Christmas presents instead! This is so exciting, oh my God, your first Christmas ever together!" He gushed with excitement, flashing Donna a huge smile.

"We agreed on not giving presents to each other, bec – "

"WHAT?" He cut her off. "Why would anybody do that?" Jack panicked with an agonized look in his eyes. "What's the point of Christmas if you're not exchanging gifts? This doesn't even make sense! No, no, no, no, no! You're gonna get something for yourselves! Kare, we're taking this lost soul out for shopping." Jack quickly found a solution for the "crisis" and now was trying to calm himself down after the shock.

"God. What is wrong with you, European people, huh?"

"Something's wrong? What did I miss?" Sam asked, as he returned after finishing his quick call.

"Donna just gave him the creeps that you're not buying gifts for each other." Karen replied. "He wants to take her out shopping."

"Oh, really?" Sam smiled at Jack, and wrapped one arm around Donna's shoulder as he sat down beside her. "Sweetheart?"

"You know that I hate shopping Sam…"

"WHAATTTT?" Jack couldn't comprehend what he was hearing.

"Donna, honey. Stop saying things like that, because you'll give him a heart-attack." Karen said, making the couple laugh as they saw the utterly shocked expression on Jack's face.

"Okay, that's it. You, Miss Alien are going to come with us. Now. End of story." He concluded with dramatic hand gestures.

"Actually Donna, would you mind going out with Karen and Jack, because I was just told on the phone that I had to pop in to the office. So this way I won't feel that guilty of leaving you alone…"

"Oh, shut up lover boy! Just give her the credit cards, and go." Karen instructed Sam. "She'll be fine with Mary Poppins and me. I promise you, she'll be back by the evening."

Donna chuckled at the firm tone Karen used, and turned to face Sam. "It's okay babe, I'm sure I'm gonna have fun with these two." She said and placed a slow, loving kiss on his lips, much to Jack's disgust.

oOo

After finishing lunch, Sam left and the three of them got up for a shopping marathon. Jack loved every minute of picking various dresses for the two women, playing around as if they were his real-life Barbie dolls. Of course it helped, that both of them had amazing figures and the money they spent wasn't an issue either. As they were walking around in Barney's, Karen and Donna both came to a sudden stop, spotting a gorgeous pair of Manolo Blahnik's. Jack stopped a few steps later, noticing the two women weren't following him anymore.

"You guys are standing under the mistletoe!" He exclaimed like a child, causing Donna and Karen to turn. It wasn't on purpose, but Donna felt somewhat happy and excited that it turned out this way, and judging by Karen's mischievous smile, she wasn't against it either. She made a step towards the brunette and gently kissed her. She closed her eyes at the sensation of Karen's soft lips against hers, savoring the slight taste of vodka on them. Lost in the moment, Donna was about to deepen the quick lip-lock, when she realized what was happening. They broke the kiss; it was already longer than it should've been. As Karen's hazel eyes met her green ones, she felt as if she was nineteen again, standing on a Parisian street with Audrey.

Audrey was the only woman Donna had ever had a relationship with. She was two years older than her, and they met when Donna was spending a year in France, Paris to be exact. Audrey was a medical student and Donna worked as a waitress in the café she used to go every day after her lectures. They bonded immediately, thanks to their open personalities and the same, teasing sense of humor. As the weeks went by, they became closer, and Audrey invited Donna to a party, where after a few drinks she confessed she had feelings for her. Donna was slightly taken aback but at the same time, she knew that what she was feeling towards Audrey was something more than what she shared with Tanya and Rosie. They spent seven months together. Audrey introduced French literature and art to the receptive younger woman and Donna formed Audrey's taste in music. She was a gorgeous woman with delicate features, long, flowing brown hair, matching chocolate-colored eyes and full, luscious lips. The amount of male attention the two beautiful girls got anywhere they went amused them. Until one day Donna spotted a handsome rocker on a concert… Little did she know then, that the guy named Harry would possibly change her life next summer. She got high on God knows what, and couldn't control herself. Audrey was heart-broken when she told her the next day, that she cheated on her. Donna asked her to forgive her the meaningless one night stand, but she had betrayed Audrey's trust, and she broke up with her. She'd never seen her again, but now, standing face to face with Karen she felt as if it was Audrey…

"Hellooooo! I'm happy you two ladies enjoyed it, but we've got to moooove!" Jack waved at them, rolling his eyes. Karen peered naughtily at Donna and barely noticeable ran her tongue along her lower lip before gently biting on it.

"We're coming honey, no need to shout."

"Come on, hurry up. I have to be at the… Oh my God, I'm already late from my date!" He widened his eyes at them as he pulled the sleeve of Karen's silk blouse up and glanced at her watch.

"Calm down Jackie, the limo's just outside. I was getting bored in here anyways… Besides, it's time to get Mr. Carmichael his present, don't you think?"

"Damn, I wanted go with you…We should've started there!" He pouted.

"Let's go honey. We're out of here." Karen motioned to Donna to get moving. They left the building, and when all of their shopping bags were placed into the limousine, they hopped in to the backseats.

"Stop in front of La Perla, then take Jack wherever he wants and come back for us. That'd be all, Driver."

They drove down on Madison Avenue, and the car pulled over.

"Thanks Kare. And have fun!" Jack smiled and leant over to give her a peck.

"You too honey." She replied before getting out of the car.

"Donna, it was fabulous meeting you doll! See you at the New Year's Eve party then, right?"

"Yeah of course, I can't wait." Donna answered smiling as she got two kisses on both her cheeks from Jack and she stepped out, following Karen. "Bye Jack!" She said good-bye, then closed the door of the car.

"Trust me, you're gonna love this honey." Karen said to her, entering the store.

"Good afternoon Mrs. Walker, nice to have you around again." The saleswoman greeted Karen, as they walked in with Donna.

"Oh, hello Kathleen."

"Our new pieces had just arrived this morning if you'd like to try them on, I'd love to bring them out for you."

"Yeah, sure, you can take one of each for me too, but we're looking for something special for my friend here. Something that would make Christmas a happy holiday for her husband too."

"Oh, I see. So Mrs. …"

"Carmichael. Hi." Donna helped the saleswoman out.

"Do you have any ideas of what exactly are we looking for, Mrs. Carmichael?" She smiled at Donna.

"Take the ones you think I'd try on." Karen cut the conversation short. Donna told her measures to the saleswoman, who disappeared quickly, going for the right sized lingerie.

"Do you see anything that you like around here already honey?" Karen asked her as they waited for Kathleen to get back.

"I really like this one." Donna took off a hanger with a tricky black bra made of silk with embroidered tulle on it. "What do you think?"

"I think you've got nice taste." Karen smiled at her. "I've got this in three colors at home." She added giggling. They browsed the hangers for a few more minutes, picking up the pieces they liked before Kathleen got back with two racks of lingerie she had brought for them. They went into the fitting rooms and started trying them on.

"Okay, I'm ready. Do you have it on? How does it look?" Donna asked Karen through the closed curtains, clasping the bra on her back.

"You tell me." Karen replied, pulling the curtains open and stepping into the rather spacious fitting room. Donna turned around and took in the sight in front of her. Karen's dark hair was partly pulled back, the rest reached her collar-bone that was fully visible now that she was standing there without her blouse on. Dressed up she was gorgeous too, but wearing from the waist up only a lace push-up bra that emphasized her impressive breasts even more, she looked utterly amazing. The cream-coloured bra on her pale complexion seemed to be the perfect match, being in sharp contrast with her black trousers she was still wearing. Donna could feel her breathing getting quicker as she kept looking at the vision, standing only one step away from her.

"Yours is good too." Karen raised a brow as she observed the sexy black bra, Donna had on. It fitted her perfectly; the expensive fabric cupped her breasts in a way that boosted her cleavage, giving it more definition. Yeah, black is definitely her color. Karen thought to herself, as she admired Donna, who was also wearing black trousers like her. She looked further up at the few loose strands of the long, curly blonde hair that framed Donna's beautiful face. She took a step towards her, and gently tucked one of them behind her ear. Feeling the tension between them, they both knew they shouldn't do what was going to happen next, but pushing these thoughts away to the back of her mind Donna leant closer and brushed her lips against Karen's. She responded immediately, sucking gently on Donna's lower lip, taking it between her owns, causing the blonde to close her eyes. Donna placed one hand on the side of her neck, and pulled her closer by the waist with her other hand, pressing their bodies together. She moaned quietly, when Karen now deepened their kiss, and slid her tongue into her mouth. The feeling of Karen's hands slowly sliding up on her sides to her back, made Donna shiver with excitement, as she held back another sigh escaping her.

"Are the colors good? You need any assistance?" Kathleen's voice suddenly made them broke the kiss, and after taking a deep breath, Karen replied to her.

"No, thank you, we're good."

"Let me know if you need anything."

"Okay, thank you." Karen answered taking a quick glance at Donna's flushed expression, then checking her own in the mirror. Her gaze returned to Donna's face, meeting her twinkling green eyes and as Donna leant closer to her, their cheeks slightly brushed.

"Think I might've found just the perfect Christmas present for Sam." She whispered into Karen's ear, and placed a seductive kiss right under her earlobe, feeling her shiver under her touch.

oOo
