Author's Notes: Normally, I write Harry Potter fan fiction. But this idea would not stop bugging me. Especially after the season finale. So I just had to try my hand at NCIS fan fiction.

I have watched NCIS since the beginning. Ever since Ziva's first appearance on the show, I have wanted her and Tony together. Don't get me wrong, I loved Kate and was so sad when Ari killed her, but Kate and Tony had a brother/sister relationship in my opinion. Ziva and Tony just have this chemistry that is on a completely different level.

Originally, I was just going to make this a one-shot. However, I think that it will be much more than that. Constructive criticism is welcomed. Downright rudeness will be ignored.

Chapter One: The Beginning

"Why can't McGee do the stake-in with Tony!" whined Ziva David, frustrated.

"Stake-out," corrected Tony, smirking a little.

Ziva glared at Tony. He was so infuriating. Why he felt the need to correct her all of the time, she did not know. So what if she butchered yet another American word. She knew several different languages. Ziva thought that it was remarkable that she did as well as she did, considering the circumstances.

Special Agent Gibbs looked at Tony, then at Ziva.

"Special Agent McGee is busy with other tasks that I have assigned to him, Agent David," replied Gibbs, grumpily. "I need you to stake-out the sergeant's home and make sure that he isn't up to something," then Gibbs added, "And if you two can't do that, you might want to start looking for another place of employment."

Ziva let out a defeated sigh. Behind her, Tony grinned widely. He was still relishing the moment where he had corrected Ziva.

"On it, Gibbs," Ziva responded, flatly.

DiNozzo began to follow her, but Gibbs whistled at him. Both Ziva and Tony looked, but Gibbs dismissed Ziva with a wave of his hand. He beckoned Tony over to his desk. Like a loyal dog, Tony obeyed Gibbs' command. He faced Gibbs in front of his desk, waiting. Agent Gibbs crooked his finger which DiNozzo took to mean come closer. Agent DiNozzo leaned forward so that his ear was close to Gibbs' lips.

"Something is bothering her, Tony. She hasn't been herself since the incident with Bodner. Find out what," Gibbs whispered into Tony's ear. Tony nodded then followed Ziva into the elevator. Once the door closed, Tony allowed his mind to wander.

There definitely was something going on with his favorite Israeli. However, DiNozzo had no idea what that was. But he intended on finding out. Being naturally curious and all.

They got into the car. He expected Ziva to ask if she could drive, but was shocked when she did not offer. DiNozzo turned on the car. The engine roared into life and DiNozzo backed out of the parking lot.

Ziva was still being silent. Not a word had been said all the way to the car. Normally, they would be bickering. However, that was not the case. Ziva was resolutely staring out the passenger seat window. Her arms were folded across her chest.

Tony hated silence. He just couldn't stand it. It irritated him. He had to break the ice somehow. It was killing him.

"I'm sorry," he said, still watching the road.

Ziva seemed to break out of her trance. She looked over at Tony, confused.

"What are you apologizing for?"

"This morning, when I corrected you," replied Tony, looking quickly at her then his eyes flew back to the road. "I shouldn't have done that."

"No, you shouldn't have," agreed Ziva, in a slightly less icy tone. "I know several languages. I—"

"Should be allowed little mistakes," Tony finished for her, flashing her a grin.

"Wow, we've been partners far too long," commented Ziva, eyebrows raised. "You're completing my sentences for me."

"Yeah, it's a little scary," admitted Tony, looking a little spooked.

"Never thought that I'd see the day that Special Agent DiNozzo was scared," said Ziva, chuckling.

"That's very Special Agent Anthony DiNozzo, and I do get scared. I'm terrified of spiders, creepy crawlers, and clowns," replied DiNozzo. When Ziva burst into laughter at the last part, DiNozzo added, "Ever watched the movie IT?"

"No," Ziva choked out through her laughter.

"You should watch it sometime. You'd change your mind about clowns too. Still gives me the creeps when I have to go near a sewer system. Don't ever tell Probelicious about that. He doesn't need to know or else," warned DiNozzo, looking menacing.

"I won't," promised Ziva, tears of laughter in her eyes.

Once they arrived at their destination, Tony and Ziva found a discreet parking spot. One where they could spy on the sergeant's house without being noticed. Tony rolled down the windows just an inch before killing the engine. Ziva pulled out the binoculars and began spying on the sergeant's house, but quickly noticed that he wasn't home.

"He's not there," stated Ziva, putting down the binoculars.

"Must've went out for a burger," suggested Tony. Good, Tony thought, Gives me time to talk to Ziva without distractions.

Ziva and Tony both sat silently in the car. Tony was trying to think. How could he ask Ziva what was bothering her and not sound like he was being annoying? There wasn't any way around it, he decided. He would just have to ask. Ziva had other plans.

"I've been meaning to ask you something since we got back from Berlin," Ziva said slowly.

Tony DiNozzo looked over at Ziva. She was avoiding his gaze. This was a very rare sight for the very special agent. He wasn't used to seeing Ziva like this. It was unreal.

"I meant every word, Ziva," Tony told her, placing a hand over hers. Somehow, he had known what Ziva was going to ask before she even asked it. Being partnered with someone for so long, you just knew these things.

"Really?" replied Ziva, looking surprised. "So it wasn't just a spur of the moment thing?"

"No, I really care about you Ziva," Tony said, placing a hand on her chin. He lifted her face so that he was gazing into her chocolate eyes. "You mean a lot to me."

Before Ziva had time to respond, Tony leaned forward and kissed her on the lips. It was not a long kiss. Just a brief, testing the waters kiss. Long enough to change everything forever.

"What about Gibbs' rule regarding inter-team relations?" questioned Ziva.

Tony sighed and lowered his head. She was right. Gibbs had a specific rule for this matter, and he had broken it. Sweeping his hair back with his hand, Tony looked at Ziva again. She's so beautiful, he thought.

"Well, we've already shattered it," DiNozzo replied with a grin. "Can't change what's already been done. But I have to ask, do you really care or are you frightened of being with me?"

"I am not frightened of anything, Tony!" shrieked Ziva, flustered. "I'm just annoyed!"

"Why?"

"Do you really have to ask?"

"Yes, I do."

"Fine," hissed Ziva, through clenched teeth. "I guess that I am frightened of being with you. I mean, what would happen if this," Ziva waved a hand between them, "didn't work out? Where would that put us or the team? It would be awkward. We would still have to see each other every day. And hear about dates with other people. How would we survive without one of us quitting NCIS?"

"I've considered this and I still don't care. It is worth the risk. Unfortunately, it has taken until recently for me to see just how much I like you. Maybe even love you. I've been in denial all of these years. I thought that my feelings for you were the same as they were for Kate. But they are not. Kate was like a sister to me. You….Ziva, you are so much more."

It was Ziva who kissed Tony this time. Unlike last time, the kiss was much longer. Ziva's slender arms wrapped tightly around DiNozzo, bringing him closer to her. Tony obliged and started massaging her back with his hands. His tongue parted Ziva's lips and met blissfully with her tongue. Their tongues began a tango of sorts. It fueled all of the pent-up feelings that were finally being released. As Tony's hands began to roam, Ziva issued a moan. Her eyes fluttered as he lightly grazed his fingers across her chest.

Headlights from a car made them look away from each other. The sergeant had returned. He was clutching a bag that Tony recognized from his favorite Chinese restaurant. Reluctantly, Tony pulled away from Ziva.

"We will continue later," Tony assured Ziva.

"I'm going to hold you to that, Tony," Ziva replied, winking mischievously.
