Chapter 14: Father and Son

Lexie woke up to the feel of a warm hand softly caressing the expanse of her naked back. She let out a long satisfied sigh, her skin tingling from the delicious sensations his hand was making her feel. She shifted slightly, drawing one of her legs over his and wrapping her arm around his torso, bringing herself a little closer.

"Good morning." Mark mumbled, his voice still a little raspy from sleep.

She buried her face in the crook of his neck and took a long breath, inhaling the smell of his skin. "Mornin'." She whispered.

"Do you know how long I've been dreaming of waking up with you in my arms again?" he whispered huskily in her ear, his lips moving erotically against the skin of her neck.

Lexie's only answer was a weak whimper as she moved to grant him better access. She scrapped her nails along his side, grinning proudly at the groan that escaped his lips.

"Mommy?"

They jumped apart quickly, the little voice taking them by surprise. They both sat up in bed, thankful they'd decided to put their clothes back on before they'd fallen asleep the previous night. Lexie looked at her son who was standing by the door, a curious look on his face. "Hi, sweetie!" she welcomed him, giving him a bright smile. She could see he wanted to join them but was a little shy. She grinned and lifted the covers, inviting him in. "Climb in, baby!"

The little boy grinned happily and ran up to the bed, jumping on top of her. Mark moved back a little, giving the boy some space to sit between them. "Did you sleep here?" Zack asked him, his dark brown eyes watching him curiously.

Mark glanced at Lexie and back at him. "Yes, I did." He answered, a little unsettled by the boy's staring.

"Why?"

"Because…" He paused and lifted his eyes to Lexie once again. She gave him a small nod, telling him he could go for it. "I wanted to tell you something this morning."

"Really?"

"Yes."

"What is it?"

Seeing as Mark seemed to not know where to start, Lexie decided to help him out. She lifted a hand up to her son's hair and softly brushed his curls back. "Remember when we talked about moms and dads? You were curious about why your dad wasn't around."

Zack nodded his head, his brow deep in concentration as he listened to her.

Lexie gave him a soft smile and glanced up at Mark. "Well, Mark is your daddy."

Mark's eyebrows raised in surprise, taken aback by her straightforwardness. He held his breath as he waited for the young boy's reaction.

Zack stayed quiet for a few seconds, analyzing the new information, and finally looked up at Mark. "Really?"

Mark gave him a small nervous grin. "Yes."

"COOL!" Zack exclaimed, giving him a huge smile.

The two adults laughed at the boy's excitement. He was probably still too young to understand what this news would change in his life, but the fact that he'd reacted so well took a lot of weight off both their shoulders.

Mark reached up and stroked his son's soft wavy hair.

"Can I have breakfast now?" Zack asked out of the blue, looking at his mother expectantly.

Lexie laughed and nodded her head at him. "Sure, bud. Go ahead, I'll be there in a minute." She helped him climb down the bed and watched him run out of the master bedroom. She then turned her attention back on the man sitting next to her, frowning at the way he was staring at her. "What?"

Mark let out a long breath and lifted a hand up to her cheek. "I can't remember the last time I was this happy." He murmured, grinning at her softly.

Lexie blushed under his stare and took his hand his hers. She brought it to her lips and kissed it lovingly. "I love you." She whispered.

Mark wrapped his arm around her waist and brought her flush against his hard body, crushing his lips to hers as he showed her how much he loved her back. Lexie moaned into his mouth, marveling at the way her whole body lightened under his touch.

"MOMMY!"

They both snickered and broke apart, unable to control their laughter. "I've got to go." She told him, but made no move to get out of his hold. She smiled and brought her face up to his, kissing his lips. She just couldn't get enough of his taste.

"DADDY!"

That seemed to do the trick. Mark broke the kiss and gave her the most beautiful smiles. "That is be the best word I've ever heard."

Lexie laughed and loosed her hold on him. "Go feed your son, daddy." She told him softly.

He didn't need to be told twice. He quickly climbed out from under the covers, grabbed his t-shirt and pulled it over his head. He gave her one last sparkling smile and jogged out of the room, leaving her alone in bed.

She lied down again and stretched her body, sighing contently. She glanced at her alarm clock and smirked when she realized Zack still hadn't lost his habit. "5:46" she murmured to herself, closing her eyes. She didn't feel tired, but decided to stay in bed for a few more minutes. The covers smelled like Mark. Plus, she could hear the two men of her life chatting happily in the kitchen.

At this exact moment, she couldn't have felt happier.

She stayed under the covers for a few more minutes and finally forced herself to get up, needing to start getting ready for the day. She couldn't believe she had to go to work… it almost felt like she was in a dream from which she hadn't woken up yet. She forced herself not to think about the fact that Mark was going back to Seattle today. They still had so much to talk about… and now that she had him back, she couldn't imagine spending a day without touching or kissing him.

She walked out of the bedroom and looked towards the kitchen, smiling at what she saw. The two of them were sitting side by side at the table, both munching on cereal. "I'm going in the shower!" She announced, smirking when they barely looked at her.

Shaking her head, she headed for the bathroom and got busy getting herself cleaned up. She didn't waste any time, wanting to go back to Mark and their son as fast as possible. When she finally made it out of the bathroom, she still had about an hour before she'd have to leave for work. She found her boys in her son's bedroom, where Mark was helping Zack getting dressed. She smiled and leaned against the doorframe, thinking she'd never get tired of watching them together like this.

Mark must've felt her presence since he looked up and grinned when he spotted her watching them. He ruffled his son's hair and stood up from the bed to join her in the doorway. Without a word, he took her hand and pulled her with him into the living room. When he was sure Zack couldn't see them anymore, he pulled her into his arms and kissed her lips, grinning against her mouth at the moan he instantly got out of her.

Lexie whimpered when he pulled back for air, her face flushed. "What was that for?" she muttered a little breathlessly.

He gave her a soft smile and let out a content sigh. "I felt like kissing the woman I love."

Her grin widened, relishing in the fact that he could tell her how he felt so openly. The Mark Sloan from four years ago would've never said anything like that. "When's your flight?"

"Noon." He sighed, giving her a more serious look. "About that, we still have to talk."

She nodded her head. "I know."

Mark took her hands in his. "I was serious, you know. About you and Zack coming back to Seattle."

"I know you were." She answered. A few hours ago, she'd been having doubts about going back to Seattle. But now, there was no doubt about what she really wanted. "And after… everything… I don't think I could stay in Boston. I want to be with you. I need to be close to you."

"So you're moving back." He asked, his gorgeous blue eyes filled with hope.

Lexie couldn't keep the smile from her face. "I am."

Mark tightened his hands around hers. "When?" he asked her, sounding like a lot like Zack.

She couldn't believe how father and son were exactly the same. "I don't know!" She answered, laughing at his eagerness.

"Come back tomorrow."

She giggled and shook her head. "I've got a lot to settle here and people to talk to. It might take a little while." He smile wavered. "And there's Sean…"

"So bring him with you! Hell, I'm so happy right now, I could even make room for your friend in our house!" He exclaimed.

"Shut up."

"I'm not kidding! We could build him an apartment over the garage and he could…"

"Mark!" Lexie interrupted him, growing annoyed.

Mark smirked and nodded his head. "Ok ok, stopping now." He sighed and lifted a hand up to touch her cheek. "When?" He asked again, sounding more serious.

Lexie gave him a small grin, her deep brown eyes sparkling. "As soon as possible." She answered. "I can't wait to be with you every day." She lifted herself on her tip toes and brushed his lips against his. Mark groaned and wrapped his arms around her small waist, deepening the kiss. Lexie returned the kiss feverishly, losing herself in the feel of his body against hers.

She whimpered when her brain started functioning again, warning her she'd be late for work. She pulled away from him and gave him a apologetic smile."I have to get to work."

Mark shook his head. "You haven't had breakfast yet." He told her, trying to pull her back to him again.

For the first time in her life, Lexie hated being such a good girl. "I'll grab something at the hospital." She said, forcing herself to take a step back.

"Don't go." He pouted, giving her his best puppy dog eyes.

"I have to." She gave him a crooked smile. "Promise me you'll call as soon as you land."

"I was already planning to." He told her, giving her a cocky grin.

Lexie nodded her head and walked over to her purse. "You can stay here for as long as you like. Make yourself at home!" She grabbed her bag and went back to him. She looked at the clock on the wall and winced. She was going to be late. "Zack! Come on, buddy, we've got to go! Come say good bye to daddy!"

The little boy quickly ran out of his bedroom and jumped straight into his father's arms. Mark smiled and picked him up, hugging him tightly. "Bye, Zack. I'll see you in a few days, alright?"

Zack pulled back and gave him a small pout. "Why are you leaving?"

Mark sighed. "Because I've got to go to work."

"Where do you work?" He asked, playing with the collar of his shirt.

"The hospital."

Zack's eyes grew bigger as an idea came to his head. "You could go to mommy's hospital! I bet they'd let you work there!" he exclaimed, looking at his mom.

Mark and Lexie laughed at the boy's idea. "I don't think so, bud. I really have to go." He told him. "But I promise we'll see each other in a few days, is that ok?"

Zack nodded his head, a small smile coming back to his lips. "Yes."

Mark grinned and hugged his son on last time. "I love you, Zack."

"I love you too, daddy." Zack answered, hugging him back.

So? Cute? Too much cheesiness? Was that what you wanted? TELL ME!

You know what to do!
