Cristina stood quietly at the surgical board her eyes glazed over with exhaustion as she surveyed her schedule for the day. Silently, she cursed herself for scheduling so many surgeries. When she agreed to having a baby, she knew that she was going to have to put in a great deal of hours to meet her fellowship requirements before she'd have the kid, but she had forgotten how grueling it was to work an intern's hours.

Meredith came to stand beside her, and shook her head at your schedule, "You work too much." She finally muttered, stifling a yawn.

"I'm trying to get in these hours so I can complete my fellowship requirements." Cristina answered bluntly, sipping at her coffee.

"Why are you trying to complete them now? You still have two years until your fellowship is up."

Letting out a sigh, Cristina glanced at Meredith, pressing her lips together.

A small smile started to creep across her lips, quickly followed by an enormous grin, "You're not."

"Shut it."

"You're not! Seriously?" Her voice was a quieted squeal, "You're joining the mommy club?"

"I am not a mommy." Cristina snapped, "And I will not go for being called mommy. Or mama. No way. I'm…" Her voice trailed off. She wasn't sure what she was going to call herself. She just knew that she was not a mommy.

"Dr. Yang? I can see it now. Your kids will call you Dr. Yang. 'Dr. Yang, can I have some cereal, please?'" Meredith mocked, still beaming.

"I'm walking away now. I have interns to torture, patients to cut." Cristina forced a yawn back down into her chest, trying to mask her exhaustion.

Meredith quickly caught up to her, "How long have you been trying?"

"What's it to you?"

Meredith whined, "I'm living vicariously. I just remember how excited Derek was when we started trying. I swear we had sex non-stop for like, hours and weeks on end. It took forever for me to get pregnant."

Cristina stopped in her tracks and turned to Meredith, "One week. Okay. We've been trying for a week. And I don't care if we are friends, I don't want to hear about McDreamy going for hours at a time. That's just nasty."

"Oh, so he's not all voracious or whatever like Derek was?" Meredith smirked, "Oh well. It doesn't surprise me."

"What the hell is that supposed to mean?"

"Oh, nothing." Meredith snickered, knowing that she could easily trigger Cristina's competitive side.

"Fine. He's like an adolescent boy that just discovered he can use his penis for something other than urination. Are you happy?" Cristina finally muttered, irritated by the challenge in her friend's voice. "McDreamy couldn't even get away with half of what Burke does."

Meredith giggled as she walked away from Cristina, "You're going to be fat and pregnant, and I'm going to laugh at you just like you laughed at me."

Cristina shook her head, "Laugh at me. I don't care. I just won't cry like you did."

"I was hormonal!" She protested, flicking back a piece of limp blonde hair from her face, "And you totally took advantage of that too many times."

"Okay, crybaby." Cristina grinned as she walked down the hall towards the fellow's office to look over a couple of charts before prerounds. She made it halfway down the hall before she felt a strong hand grab her arm and guide her in the opposite direction.

"Dr. Yang, might I have a word with you for a moment?" Burke uttered in a low voice, glancing around to ensure that the halls were mostly deserted before ushering her into a call room.

"Burke, I have a surgery in an hour, and this clearly breaks the work rule." She protested half-heartedly. If she were to tell the truth, she wasn't that mindful of breaking the work rule. It had been years since they'd taken advantage of the call rooms in the hospital, opting instead to play their game.

"What work rule?" He mumbled as he pressed her against the door, his lips coming down softly on hers. He grazed his hands under her navy scrub top and over the soft skin of her sides, eliciting a moan from her lips.

Cristina gave into him easily under his teasing ministrations. She couldn't ever think straight when he touched her. And he took full advantage of that, "Fine.." She feigned annoyance, "But I have to be in surgery in an hour. I have a full schedule."

He pulled away from her, letting his hands drop to his side, "Okay, Dr. Yang. We can hold off until later, if you prefer."

Grasping at his sides, she pulled him back to her so that their bodies were flush, "What? You can't work under a time restriction?"

He grinned against her lips as he resumed where he'd left off only a few moments earlier, "I'll have you in surgery on time, Dr. Yang."

Exactly one hour later, Cristina stood over her 67 year old patient with a smile well hidden below her surgical mask and her thoroughly tousled hair disguised beneath her pink surgical cap. The exhaustion had left her body and she couldn't help that think the rest of her day might actually go smoothly.
