A/N:
So, I came up with this idea way back when we first the spoilers about Ziva and Tony's father going on a date, but I never got around to actually writing it down until a few days ago (before the promo...).
As usual it didn't out at all like I'd had in mind, and it doesn't really have anything to do with how it's going to happen on the real NCIS.

I realize it's completely OOC, but I DID write this down really fast one evening, which is also why there will likely be quite a few mistakes (since I didn't proof read or get it beta'd)...
And I myself am not too happy with this (think it turned out really bad).. But figured I'd upload it anyways...

I hope you'll still enjoy it, though :D
And I would be the HAPPIEST person alive if you'd leave me a review.. Good/bad, long/short, I don't care! :)

(And no, English is NOT my first language, so I apologize in advance for any mistakes...)

Backfire

Taking a sip of his coffee, Tony leaned back against his front row seat in MTAC. It was Friday night, and while he'd give up just about any plans he could have for a chance to see Ziva all dressed up and looking sexy for a date, this was the last thing he'd ever dreamed of doing.

Not even in his wildest and scariest nightmares had he ever imagined Ziva and his father. On a date.

Sure, in the back of his mind he knew it wasn't real, that they were just acting. That they were undercover. But just the thought of the two of them together made the bile rise in his throat, so he had to physically force himself to not tear his eyes away from the screen in front of him.

There were so many different emotions running through him that he wasn't even sure what he was currently feeling. He knew he had no right to feel so protective and possessive of his partner, but he couldn't help it, and it really didn't match with that somewhat kinky feeling he got whenever the two people on the screen got physical.

He'd given up attempting to not get turned on by Ziva in that tight dress ages ago though, and that annoyed him even more. Yes, she was damn beautiful, there was no denying that, but she was his partner and his best friend, and seeing her like that with his father of all people should have the opposite effect.

"Running all the faces now, Gibbs."

"That's a good job, Abs. Go back to the overview of the entire restaurant." Tony let his eyes close for a few seconds in relief, both from knowing that Gibbs was seemingly as uncomfortable as himself but also from getting away from the view from his father's camera reading classes. Even with all the instructions they'd continuously given the older DiNozzo through the microphone, his gaze had mostly stayed glued to Ziva's chest, leaving her to catch a view of everyone in the restaurant with the camera stuck below her purple headband while keeping up her flirtatious cover.

Thinking back over the past week, Tony swallowed the rest of his coffee in one go to prevent a yawn. It all started when a marine daughter, just 18 years old, had been found strangled to death in a park, 'gold digger' engraved right above her bikini line.

After some research they'd discovered that there had been quite a few killings with the exact same MO throughout the East Coast and that the FBI was already working on the case. It seemed that someone had decided to kill females who dated men much older than themselves, men with lots of money. It appeared they even knew which group of people the killer watched, and it just so happened that Tony's own father was part of that social group.

So since the FBI, like always, was too incompetent to catch the killer, Gibbs had insisted they could have their own attempt at solving the case. And before Tony had had a chance to blink his partner was playing bait, going on a date with a man more than twice her age and acting like a complete bimbo, physically all over his father.

Oh, this was going to be a very long night.

Picking up the glass of expensive red wine in front of her, Ziva twirled it around the glass for a few seconds before slowly sipping the wine, keeping her head low so she could look up at the man in front of her through her darkened eye lashes.

She hadn't expected to ever do this again, to use her looks and her body to this extend as she thought she was done with this type of undercover work by leaving Mossad, but it seemed she'd been mistaken.

Carefully placing the crystal glass back down on the table she accepted the piece of steak held out for her, closing her eyes as she leaning over the table to pull the food off the fork with her lips and moaning deeply before licking her lips and slowly reopening her eyes.

The sound of Tony sputtering out what was most likely his coffee in her ear wig caused a smirk to cross her lips, but looking at the older Tony in front of her she made sure it seemed as if it was directed towards him as to not blow their cover.

"Have I mentioned yet how astonishingly beautiful you look tonight, baby?" Leaning into the hand currently caressing her temple, Ziva let her own hand cover his bigger one as she placed a seducing kiss on his palm before running her fingers lovingly over his arm, letting them travel inside his sleeve.

"Only about every 5th minute, my love." Using her free hand to throw her long, straightened hair over her shoulder, she tilted her head in just the right way for the lines in her slender neck to stand out. "But you know I love it."

"Gosh, Ziva! This isn't a porn movie, so turn down the charm!" The loud smack from Gibbs' hand colliding with the back of Tony's head reverberated through the speakers in their ears and Ziva had to pluck a tomato from her salad into her mouth to prevent a giggle from escaping her throat.

Yes, she knew she was acting nothing like herself, but if they really were being watched, which was highly likely since most of the murdered women had been taken to this particular restaurant for a date shortly before their death, she had to be very convincing in wanting to seduce and act completely in love with the older man at the table.

And she'd never pass on a chance to mess with DiNozzo, especially since she was so experienced in this type of work that it didn't faze her the slightest, even if it was her partner's father.

"Well that's fortunate, cause I don't think I could stop admiring you even if I tried." Ziva just let out a throaty laugh as DiNozzo Sr. let his hand rest on her knee under the table, running it further up her leg than she'd felt comfortable with, but that wasn't something she'd ever let show.

She just cursed the fact that she was a better actor than her current undercover partner. It was obvious that he took her actions too personal, and not just for the acting that it really was. That he himself wasn't exactly acting his part.

"Oh God, boss. Please tell me we have enough. Abby, any hits yet?" The small peck his father had placed on the beautiful ex-Israeli's cheekbone would cause Tony just as many nightmares as the soft, lingering kiss Ziva had applied to his lips. Of course, Tony could just be imagining things, something he desperately hoped was the case when Ziva's hand seemed to visibly travel way too close to that one place he really didn't want it to go.

Damn her for knowing exactly how to pull this off! And then acting so casual about it...

"Well, a few people showed up in different data bases, some with criminal records, but so far we haven't found anything on any of them that seem suspicious or like a cause for murdering these women. We'll of course dig deeper, but nothing screams 'killer' on any of these people. Neither the staff nor the guests. So if they're there, trust me, they'll have noticed Ziva and your father by now, cause.. I mean... I think it's fairly obvious that like every single guy and most of the women in that room has been staring in that direction at least, like, 10 times."

"I get it, Abby. I get it! Please, boss?" He gave his boss his best puppy face, and having studied his mentor's reactions throughout the dinner, he knew Gibbs felt uneasy about the situation as well. Although he suspected it was also partially due to the case, and not just purely from seeing his partner and his father so affectionate with each other as was his own case. But he also knew that that had a big impact on the older mad as well, as he obviously didn't like or trust the older DiNozzo and Ziva meant much more to him than just a college. A part of his family, like the rest of their team.

But at least Gibbs kept in mind that Ziva was a professional at what she was doing.

Sending a quick look towards the computers where McGee and Abby were running all different kinds of searches, Gibbs returned his focus to the 4 different camera angles on the MTAC screen.

"Nice job, Ziva. There's nothing more to do in there, so if you're done eating, head out." Gibbs knew both of them were able to hear them, but he still found it awkward addressing the older DiNozzo in the same sentence, so he stuck to just communicating to Ziva whenever he could get away with it.

"And keep up the pretense till you return to the house. We're counting on the killer following you and attempting to strike tomorrow." The last instructions were meant mostly for DiNozzo Sr, as they all knew Ziva would know how to handle a mission such as this, and Gibbs wanted to be sure he remembered his few 'scripted' lines.

Sending his senior field agent a quick glance he received a grateful smile, one he automatically returned before return to the screen and his ever present coffee cup. While they both felt incredibly relieved that they could end this awkward dinner, at least awkward for those watching, they knew it was still far from over.

They were hoping that the killer had seen them, and that he or she would follow them when they left. It seemed that all the other killings had happened as soon as the woman was on her own and easy to get to. So Ziva and Anthony DiNozzo Sr were spending the night together in DiNozzo's fake mansion in the hopes that it would be enough to draw the killer out.

Whoever it was had been stupid enough to leave a finger print on one of the bodies, one that wasn't in any database, so if they caught the person just observing the house rather than actually attempting anything with Ziva, they'd still have enough evidence to convict him or her.

Getting the welcomed signal that they were okay to leave, Ziva made a big deal out of sighing as she leaned back in her chair.

"I am stuffed, my love." She swung her hair through over her shoulder as she let her hand run over the wide, smooth, dark purple silk ribbon that was tied around the waist of her blood red silk dress.

"You want some dessert, gorgeous?" She felt like puking at some of those pet names, but forced herself to look flattered in stead.

"Well," Leaning back over the table she carefully traces the slight stubble on his chin, a fake pout adorning her face. "Since you will be gone on meetings all day tomorrow," Changing her pout into a a seducing smile, Ziva let her foot slip out of her stiletto to trace her toes up his leg under his pants while letting her index finger travel over the curve of his lips. "I had some... different type of dessert on mind." The obvious grin on his face spoke volumes, and Ziva knew it was a good thing she'd mentioned him being gone the following day, cause he'd obviously forget to voice that detail himself.

"Have I ever mentioned that you're just as smart as you are hot?" When her only reply was a very inviting smirk, DiNozzo Sr absentmindedly threw a hand in the air. "Waiter!" For the few minutes it took for the waiter to run DiNozzo's credit card through, the two people just stared at each other and acting completely stuck in some sexual fantasy, at least on Ziva's part, who was busy biting her index finger.

"Let me, beautiful!" Following the older man with appreciative eyes as he walked around the table, Ziva let him pull out her chair for her and pull her p by her hand. She then placed the shiny silver purse in the crook of her elbow before rising up on her toes to place a soft kiss on his lips as her way of saying thanks.

Even though she wanted to she didn't protest when he placed his arm around her waist to pull her close to his side, his hand quickly traveling down to grab her ass as he let her towards the restaurant's exit, completely aware on how everyone were staring at them.

Knowing she'd have to play along, Ziva copied his motion and gave his butt a quick squeeze before returning her arm to her side, letting him steer her out as if she was some sort of accessory. But of course, that was her cover.

"You cold, babe?" Stepping just outside the door of the restaurant, the cold November air quickly assaulted them. Unable to prevent the goosebumps from appearing on her arms, Ziva couldn't really say no to the offered coat if she wanted to stay in character. So when the much too big coat was placed on her bare shoulders, Ziva once more leaned up to place a kiss on his lips, knowing that they might still, and likely were being watched. However, the hand placed on the back of her head forced the kiss to last much longer than she would have liked, but not wanting it to look suspicious, Ziva forced herself to bring her hand to his hair while holding on to the coat with the other.

"Tony..." The word didn't come out as more than a mumble as her lips were still pressed against his. Wanting to get out of his hold without giving anything away, Ziva let her hand travel to his chest where she grabbed his shirt into a fist, attempting to softly push him away.

"You taste amazing, baby!" Trying to mentally rethink how much her current counterpart had been drinking distracted Ziva enough for him to allow his hands to roam down her upper body and push her up against the brick wall.

"How about continuing this at home?" When the only reply she got was two hands gripping her hips firmly and a mouth her neck, leaving wet traces behind, she really had to force herself to let out a giggle since she knew they had an audience.

She was very well aware of the coughs and the questions coming through her earwig, but the hand traveling up her body to rest on her breast had her mind too occupied to make out exactly was was being said. She didn't have a chance to protest when DiNozzo Sr. used his other hand, still by her hip, to lift her leg up and placed it around his hip so he could step even closer to her because he at the same time returned his mouth to hers, this time desperately trying to add his tongue to the kiss.

"To..." She wanted to tell him to release her, but her plan backfired as he used her open mouth as an opportunity to slip in his tongue. By now the sounds and voices in her ear were just a big blur, and even if she tried to decipher them she wouldn't have any luck.

Forcing herself to join in on the kiss for a few seconds she let her hands move up along his arms and his neck to the back of DiNozzo Sr.'s head where she grabbed his hair, trying to pull him away from her face while keeping up the illusion that she was just as into this as he was. A hand suddenly traveling up the inside of her leg beneath the knee length dress caused her to let out a gasp, but instead of taking the hint and releasing her, the poking on Ziva's thigh told her exactly how his body was reacting.

"Stop..." Her voice was ragged and sounding out of breath, but while it was caused by the was starting to rise in Ziva, she suspected he would understand it differently, something that was equally good and bad since they wanted it to look that way for those watching, but unfortunately DiNozzo Sr. seemed to forget that this wasn't real.

"But we're just getting to the good part, baby." His mouth returned to sucking its way down her neck as his hand came to rest between her legs, his fingers never seizing movement or letting her underwear stop them from reaching their intended destination, which caused a gasp to escape her throat as if she'd gotten punched in the stomach. But as she'd feared, DiNozzo Sr. understood it all wrong and took is as an invitation to continue.

"Let's move this back to your bed." Again her voice wavered and broke for different reasons than being turned on, and Ziva had to fight not to push him off of her or seriously injure him

"I didn't think you had a problem with some PDA. At least I don't." Ziva just closed her eyes and leaned her head back to prevent herself from crying out as his hands continued to roam her body.

"McGee! Get me a better view!"

"I don't know, boss. There doesn't seem to b..."

"Got it, bringing it up!" Before Abby had even finished her sentence, the view of the darkened parking lot appeared on the screen instead of that from Ziva and Tony's cameras. The forensics scientist had hacked into a public security camera which showed the entire parking lot in front of the restaurant, currently populated by quite a few people besides from the NCIS agent and her 'date'.

"Make 'em stop, boss!" Having to watch the scene unfold in front of him was bad enough, but hearing Ziva's continuously murmured stops and not here's and not now's and please and Tony's was just too much to bear. Sure, for anyone else it might seem like just a heated, a really heated make out scene with two people getting very physical with each other, but it was obvious to everyone in the room, those who knew Ziva really well that she was serious, and she sounded so very close to panicking.

"DiNozzo! Drop it! Return to the house!" They'd been trying to get through to the 'couple' for what felt like ages to Tony, but they had yet to respond to anything that was being said.

"Why isn't Ziva stopping him? She should be more than able to push him away!" Gibbs barely spared his desperate senior field agent a glance before his eyes returned to practically burning a hole on the big screen with his hard glare when Ziva attempted to conceal a whimper as a moan. No one commented on what took place in their own room when Tony fell to his knees in the corner, emptying his stomach contents at the sound of his father eliciting those sounds from his partner.

"Dammit, Ziva, just abort the mission!" Gibbs knew it might be highly unprofessional, but while the mission was of extreme importance, it wasn't worth his agent being traumatized because she refused to slip up. She didn't seem to hear him though, just like all the other times they'd tried to communicate, and somehow it didn't surprise Gibbs.

It wasn't until multiple agonizing minutes with lots of unanswered demands through the microphone later that their movements on the screen seemed to halt.

Ziva's body shook almost undetectably to the trained eye as she leaned up to place a kiss on the much older man's cheek, never letting go of his hand in the process.

"Come on, my love. We have much to finish at home." While her voice was back to that playful, seducing tone as she threw her hair over her shoulder and started walking towards the street to hail a cab, her hips swaying with every step, the people in MTAC knew she was very shaken up, but like usual Ziva would rather die than admit to that.

Ripping the microphone off his head, Gibbs threw it through the room the second they'd entered the cab, making it crash against the wall before almost running up the stairs. He needed coffee.

Anthony DiNozzo Sr. had barely entered the downtown office currently borrowed by NCIS before his son slammed him up against the wall, his arm firmly secured over the older man's chest so he couldn't easily escape.

"You idiot!" The baffled look on his face was enough to make Tony give him a hard shove before taking a step back, his eyes burning with rage.

"Nice to see you too, Junior..."

"What the hell is wrong with you?" When DiNozzo Sr. just raised his eyebrow, strolling past Tony so could plunge down in one of the chairs, the NCIS agent made fists out of his hands to prevent himself from hitting something.

"You almost cost us this entire mission, jeopardized everything because you're too horny to follow the instructions." The smirk appearing on his father's face and the glint in his eyes made Tony want to shoot him. Or puke. He wasn't sure. "You were ordered to stop!"

"Come on, Junior, we were having fun!" The big smile he offered his son showed just how clueless he was about the whole thing.

"Fun?"

"Yeah, and it was about to get much hotter if you guys hadn't ordered her to stop." Even through his burning rage Tony couldn't miss the big mark on his father's hand when he held it up, and suddenly the hand holding from the day before made sense, as it seemed Ziva had had to retort to pressure points to get away without seeming conspicuous.

"We didn't order her to stop, we ordered you to stop! And so did she!" DiNozzo Sr. crossed his hands in front of him and let them rest on his stomach as he leaned back in his chair.

"Sure seemed like she wanted it to me..."

"Well she didn't!" The loud smack from Tony slamming his hands on the table didn't seem to faze his father at all, and for a few moments they just stared at each other.

"But can you blame me? It's not my fault she's such a tease!"

"A tease?!" Tony was completely dumbfounded. Hadn't his father understood a single thing about this mission? "She was doing her job, dad. Something which didn't entail almost having sex in the parking lot!"

"Well if she wanted me to stop that badly she could've just told me or pushed me away."

"She did!" His father's confused look just caused Tony to become even more furious.

"Didn't sound very serious, then." Taking a deep breath, Tony forced himself not to explode when his father shrugged his shoulders.

"Of course not, because she's too professional to just blow her cover like that!" It wasn't until the words had left his mouth that Tony realized he was almost angry at Ziva. If she had cared jut a bit more about herself rather than the case they likely wouldn't have ended up in this mess.

"Well if she's so professional then shouldn't she be able to handle a bit physical contact without it being the end of the world?" Had this been 2 years ago, Tony knew his partner wouldn't have even blinked at how things turned out the evening before. But it wasn't.

"Not after what she's been through!" Realizing too late that he'd said more than he should, Tony turned around and stormed out of the room. He'd barely even reached the end of the hallway before the ringing of his phone interrupted his internal cursing.

"What?"

"Caught he guy." Hiss boss' calm voice was enough to make him halt his movement completely.

"Ziva?..."

"..Is fine. Kicked the guy's ass before we'd even raided the house." A relieved sigh escaped Tony's throat as he let himself collapse against the wall. "Get your dad and bring him back here so we can debrief." He didn't even have to hear the dial tone to know that Gibbs had hung up. He had simply worked with him for too long not to know how he worked.

Groaning, Tony pushed himself away from the wall, reluctantly moving back to where he'd just left his father.
