A/N: Okay, so me and Nina are back with a new story. We just love Paddie too much.

Anyway, this is AU. It involves Mark though because you've jsut got to love him. Basically, Addison and Pete have a fling and Addison falls pregnant, and in love with Pete, but they can't get together until his daughter is okay with them. The story is much better than my summary.

Enjoy.

Addison Montgomery sat on the edge of her bed, gripping hold of the white stick in her hand. It was positive. The test was actually positive. She was pregnant. She was carrying around another human being. She had created another human being. The thoughts somersaulted in her mind. What was she supposed to do now? She wasn't even in a relationship, it was just a fling. A holiday fling for him. He didn't even live in New York; she didn't even know where he lived. She was carrying his child and there was no way she could even tell him that he was going to be a father. The father of her child. She sighed and lay down on the bed, not knowing what to do.

Addison placed the pregnancy test on the side and stared up at the ceiling. She was going to become a mother. She was actually going to have a baby. A baby. This was a good thing, right? She'd be a mother. She wanted to be a mother, only this was not exactly the way this was supposed to happen. She was meant to be married, or at least in a relationship where she new they would end up married. She was meant to be with someone she loved and they loved her back. She wasn't meant to be a single mother.

God, how could she have let this happened? She wasn't like that; she wasn't the kind of woman who got knocked up by a man she barely knew. Addison wasn't the type of girl to have flings, but there was just something about him that she couldn't resist. He just seemed to be everything she had dreamed of, and spending just that one week with him had been heaven. But then he had to go back, to wherever he came from. And now? She had not the slightest idea where to find him.

She could look him up on the internet, but it might not be such a good idea. He probably didn't even want this baby. This was just a fling to him, just some fun for the week he spent here. Nothing more. He wouldn't want to settle down and have a family. It was probably best she didn't tell him about this baby. What if he was married? God, what if he had a wife? Kids waiting for him at home and a nice house on the beach? She couldn't do that. She couldn't tell him that she was pregnant, only to end up rejected as the woman he cheated on his wife with.

Addison sighed and turned onto her side. She was not the sort of person to end up in these situations, it more like something that Archer would do. He was the one who would end up as a parent from a fling. She was actually surprised he hadn't managed to get anyone pregnant with his many flings, it was her first one. The first time she did something like it. Having fun without any commitment and he went as fast as he came.

She wasn't sure she could even remember what he felt like. What it felt like to be in his arms, for him to pleasure her like only he had done before. And suddenly it came back into her mind. The way he looked at her, touched her, kissed her. Addison smiled, curling up into a ball as she remembered the time they spent together.

Pete was sitting in a bar, sipping at his drink and watching the people around him. He raised an eyebrow as a redhead caught his eye, and he just watched her dance, before she stopped and walked over to the bar to get a drink. He watched as she ordered another Martini, her girlfriends still on the dance floor. She leaned against the bar next to where he sat as she waited for her drink. He took another sip of his drink and smiled at her as their eyes met. She smiled back and tucked a strand of hair behind her ear.

"That's on me." Pete put some money on the bar as her drink arrived.

"Thanks." She smiled and took a sip. "I'm Addison." She held her hand out to him.

"Pete." He smiled back as he took her hand.

"Nice to meet you." They shook hands and Pete smiled as he looked at her. She looked stunning with her red curly hair hanging loose from her shoulders and the small black dress and high heels she wore. Addison took another sip if her drink and looked at him, she didn't think she'd ever seen anyone as handsome as him.

"I saw you dancing before." He smiled.

"Oh." Her cheeks blushed.

"No, I liked it."

"It was embarrassing."

"No, not at all."

"It was." Addison nodded.

He smiled at her. "I liked it."

"Thanks." She smiled. Pete smiled back and took the last sip of his drink. "So, are you here alone?" Addison looked at him, wondering why a guy like him didn't have a girlfriend with him.

"Yeah." He nodded.

"I would have expected you to be here with someone."

"Would you?" He smiled.

"Yeah, I can't imagine you being single for long."

"What about you?" He looked at her.

"Just here with friends." She motioned to Savannah and Jenna on the dance floor.

"I see." He nodded. Addison smiled and took another sip of her drink. Pete looked at her before he ordered another drink.

"Do you…erm…do you maybe, want to dance?" Addison looked at him.

"Dance?" He looked over at the dance floor. "Yeah, why not." Addison finished her drink before placing the empty glass on the side and taking hold of his hand, leading him onto the dance floor. He smiled as he followed her through the crowd. She turned to face him once they found a spot and began to dance very close to his body. Pete started to dance as well, his eyes on her, watching as she moved to the music. Her arms linked around his neck, her body rubbing against his as they began to move together. He moved his hands to her waist and pulled her closer.

Addison smiled and moved as close as she could to him, moving to the music the whole time. Pete smiled and looked into her eyes, her body pressed against his. She looked back at him, feeling their gazes lock. The continued moving and he glanced down at her lips. Addison watched his eyes the whole time, watching as his gaze shifted. He felt her body rubbing against him and inched his face closer to hers. Addison let her eyes close and she moved her face closer to his as well. Pete leaned forward and closed the gap between them, his lips softly touching hers. She instantly kissed him back, her arms tightening around his neck. He pulled her even closer, moving his hand from her waist to her back

"Do you want to stay here, or go somewhere else?" Addison whispered into the kiss, kissing him hungrily.

"Let's go somewhere else." He whispered back.

"Mine?" She continued to kiss him.

"Yeah." He mumbled against her lips.

"Okay."

He pulled away after a few more seconds and took her hand in his, leading her to the exit. Addison led him to her car, the both of them getting in before she drove to her apartment, before they stumbled their way in, kissing the whole time.

Pete pressed her against the door while they kissed and she fumbled with her keys. Addison tried to find the right key and kiss him at the same time. She managed to succeed and after many attempts the door swung open. They tripped in and Pete kicked the door closed behind them. Addison wrapped her legs around his waist, not breaking the kiss once. He moved his hands to her thighs as her back came in contact with the wall next to the door. She let out a moan, rubbing her hips against him. He felt her movement and let his hands slid further up.

"Oh…god…" Addison began to kiss his neck, sucking on his soft flesh. He squeezed her thighs and moved his hands under her dress. She sucked hard on his neck, nibbling slightly. He let out a moan and explored her body under the fabric of her dress. Addison pulled back once she was satisfied that she had given him a hickey, before she began to kiss along his jaw.

"Where's your bedroom?" He whispered, grabbing her ass.

"The one on the right." Addison kissed him again as he began to carry her to her bedroom. He kissed her back and walked into her bedroom. Addison kicked the door shut with her leg that was wrapped around his waist before he laid her down on the bed. He ran his hands down the sides of her body, never breaking the kiss. She began to pop the buttons on his shirt, before she slid it off his shoulders and down his arms, throwing it to the floor. His lips barely left hers as he reached behind her to unzip her dress while Addison lifted her body up, letting him pull down the zipper before he slid the dress from her body. He threw it somewhere onto the floor and looked down at her bare skin, his gaze shifting to her breasts.

Addison looked up at him, her lips swollen from all the kissing. He leaned down and started to kiss her neck while he unclasped her black lacy bra. She moaned softly and popped the button on his jeans, before she pulled down the zipper, pushing his jeans off his hips. Her breasts sprang free and the straps fell from her shoulders while his mouth made its way to her chest. Addison let out a moan, a hand running through his hair as he kissed her chest. His lips brushed over her breasts and he sucked slightly.

"Pete…" She breathed, her eyes closed. He continued to kiss her and his hands ran down her stomach to the hem of her panties. Addison felt a shiver run through her body at his touch, no man had ever made her feel like this before. Pete's lips kissed further down her stomach and he slowly slid her panties down her legs. She moaned, feeling herself become wetter than she already was. He returned his mouth to hers then and slowly ran a hand up her inner legs.

Addison shivered from his touch, pushing his boxers off his hips so he was revealed to her. The sight of her made him very hard, his erection brushing against her. She let out a moan, wrapping a leg around his waist. He moved and slid into her slowly. Her head dropped back against the pillow and she wrapped her other leg around him. Pete started to thrust into her, his mouth colliding with her neck once again. Addison moaned softly, her legs moving higher up his back so she could take him in deeper, moaning loudly when he went deeper.

His hands were all over her body, her reactions making him move faster. She moved her mouth to his shoulder, placing kisses there as she met his hips with her own. He groaned against her skin, a hand resting on her hip. Addison could feel him hitting her g-spot continuously before her orgasm washed over her body and she moaned his name. He came at the same time, moaning in pleasure.

They just lay in each other arms, both of them sweaty and breathing heavily. A smile was playing on Pete's lips as he tried to catch his breath.

"Wow." Addison grinned at him. "That was just…wow."

"I know." He smirked. She smiled and kissed him again. Pete placed a hand on her cheek and kissed her back.

"How long are you here for?" Addison whispered into the kiss.

"A week."

"And you're here alone?"

"Yeah, for work."

"Do you want company when you're not doing work things this week?" Addison looked up at him.

"Sure." Pete smiled.

"Okay." Addison smiled before kissing him again.

Addison sighed at the memory and rolled onto her back, staring up at the ceiling again. Everything had been perfect for that week, everything. Why did she have to do this? Why did she have to get into something as perfect as that was when she knew that it would end so soon? She sighed and cursed herself. Why did he have to leave? Why did he have to go and leave her when everything was so perfect? She didn't even know a lot about him or his life, actually she knew almost nothing. But what she did know was how wonderful he made her feel.

Addison had connected with him like she had connected with no other. But she had to stop thinking about that now. About him. He was gone, she had no idea where to and was probably never going to see him again.

Addison sighed and let her hands wander to her stomach. She had a life growing inside of her. A life that was also a part of him. A tiny little life that they had created together, a life that was going to depend on her completely. She moved her hand over her flat stomach. She didn't have a father for her baby. What was she supposed to say when they're old enough and start asking questions? That their dad was just a fling? Just the most wonderful and perfect one she'd ever have?

She couldn't tell her child that. She wouldn't tell them that. She didn't know what to say, but she still had lots of time to figure that out.

Addison turned over in bed, picking up her phone, dialling her friends number before she heard her answer.

"Hey Nae, I need a favour."
