Warnings: Please note the rating change from "T" to "M". There is adult sexual content in this chapter.

A/N: Because of the rating change to "M" I just wanted to leave a note stating that not every chapter is going to have a sex/love scene in it. I will try to clearly warn you before each chapter if this kind of thing is not your thing. I won't be offended if you skip those chapters. I tried to keep this chapter closer to the "T" rating but well, Tony and Natalie... they just... wouldn't let me haha.

Ducky was not surprised that Gibbs showed up at the hospital alone. "Send Anthony and Natalie home for the evening?"

Gibbs frowned, slightly. "Yeah. Only for a bit. Vance sent them on assignment."

"Assignment? Where?"

"Paris?"

Ducky suddenly understood his pensive state. Gibbs was still uncomfortable about the idea of Tony and Natalie being together, but he didn't want to stand in the way of the two agents. The medical examiner chuckled. "If it has not happened already, you are worried that it will happen in Paris, hmmm?"

Gibbs shot his old friend a heated look. "I don't know what you're talking about, Duck."

"Please. You absolutely know what I'm talking about. Sex."

"Being awake for all these hours, watching over Tim, has made you crude, Duck."

Ducky shrugged his shoulders. "Perhaps. Either that or I just do not care as much in my old age." He glanced at the team leader for a second, noticing that the fine lines were fading now that Ducky had dug up what was bothering him. "Tony and Natalie are not you and Jenny. Maybe this is more to them than a love affair, or casual sex. Besides, if they haven't done it yet... it will be incredibly difficult to resist in a city such as Paris."

Gibbs leaned back in his chair in the ICU waiting area and nodded. "To be honest, Ducky, I don't think they've taken their relationship that far yet. I think a small part of Tony is concerned that he's making a mistake, that I won't approve of this." He grinned, devilishy at the medical examiner. "I could have easily argued with Vance to send me to Paris with Natalie and not Tony..."

"So you let him in the hopes of..."

"Yes. I let him in the hopes of him getting his act together and making a move before it's too late."

Ducky chuckled, silently. "You, Jethro, are sneaky. And still, after all these years, full of surprises."

Gibbs just grinned and hoped his ploy had paid off.

Paris, France. Tony had his romantic notions about the place and he certainly didn't think the first time he'd be taking Natalie here would be on business. He slid the key card into their hotel room door, unlocking it and opening it. He glanced behind him at a rather tired looking Natalie. If only they hadn't made that stupid pact to keep their relationship separate from their work relationship.

Tony sighed in frustration and stepped aside to let her into the room. He followed behind her, closing the door. Looking around it was cozy enough. Inviting and romantic, with a queen sized bed. Figures. He caught a glimpse of a sofa that he hoped pulled out because he didn't think it would be a good idea to share a bed with Natalie, not when he wanted to pull the clothes off of her body and make love to her… over and over… think about something else DiNozzo!

Natalie plopped her suitcase down onto the rack, startling him. "I'm going to take a shower, wash the smell of pressurized cabin off," she said, grabbing up some lounge clothes and a clear plastic bag from her luggage.

Tony found himself wishing she'd ask him to join her. But she didn't and she disappeared into the bathroom. Shouldering out of his suit coat, he dropped down onto the bed, laying down on his back and covering his face with his hands. It had been months since they had come clean with this electricity between them, just a week since they decided to try their hands at being more than partners. He thought he would be able to get through this little overnight jaunt to Paris without craving being with her… In fact, he concluded as he heard the shower turn on, being in Paris had only made it worse.

"Damn it," he grumbled as he got up from the bed and headed towards the bathroom.

He grabbed his tee shirt and lounge pants and opened the door without knocking, figuring that Natalie was in the shower. He was surprised when she gasped in shock and found her standing in front of him completely naked. Tony gulped and mumbled some kind of apology and started to back out of the room, trying to hide the fact that he was very, very turned on at the moment.

She didn't even bother to grab a towel to hide herself from him, unashamed that she was showing everything to him. "Tony. You know… technically we're not on duty until tomorrow morning," Natalie said, stopping him dead in his tracks.

His hand tightened around his clothes and he looked at her again, in all of her naked glory, his heart beating madly that he could see every sensual inch of her. Was she suggesting what he thought she was? One look into her heavy lidded, desire filled gray eyes told Tony that, yes, she was. He dropped his clothes outside the bathroom and strode into it, grasping her into his arms and kissing her, passionately, letting his hands run up and down her smooth flesh.

She pressed her body close to his, aware that he was completely clothed while she stood there with nothing on, the shower water running behind them. Slowly she tugged his shirt out of his pants and undid the buttons, sliding it off his board shoulders. His arms wrapped around her waist and she allowed his tongue access to her mouth, eliciting a low moan from his throat. Gasping for air because he was taking her very breath away she found the buckle of his belt. His hands reached down and helped her undo it, helped her get his body out from the offending slacks, ridding him of his boxers.

Tony's clothes were now in a pile on the bathroom floor with hers. "It's not fair, Ms. Callahan… I didn't get to undress you," he whispered, heavy, husky, and he planted a kiss in the hollow of her neck.

"You've undressed me enough with your eyes over the last several months," Natalie teased, arching her neck back, exposing the soft skin.

"But reality trumps fantasy… at least in this case, darling," Tony offered, letting his fingers glide up her thigh. He smiled against the soft skin of her neck, leaving kisses there, and relished in the moan when his fingers found their destination.

Natalie pulled back and gently removed his hand, much to his protest and a bit to hers. But she threw the shower curtain back and stepped inside, allowing the hot water to engulf her body, soaking her.

Tony yanked his only remaining clothing off—his socks and shoes—and stepped into the shower with her, pulling the curtain shut. He took her face into his hands and kissed her, hard, the water splashing over him and drenching him as well. She reached behind her and managed to find the small bottle of body wash, never breaking their contact. Soon the shower was filled with the scent of honey and flowers, and Tony felt his pulse racing as Natalie lathered the soap in her hands.

Gently she massaged his shoulders and back, washing away the grim from a full day's worth of traveling. She moved up and down his body until he was completely covered in the feminine smelling soap. He didn't feel very feminine as his eyes found hers through the stream of water and his lips zeroed in on her mouth. It was hard to feel girly when his arousal was firmly pressed between her legs at the moment, as he grasped the bottle of body wash in his own hands and began to give her the same pleasure she had just given him.

"Honey is never going to be the same for me, Nat," Tony informed her. His hands explored the firmness of her breasts, the perk of her nipples. "I'm going to picture you, naked, underneath a shower stream, lathered up and I think it's always going to turn me on."

"Well, won't that be embarrassing the next time Ducky asks you if you want honey in your tea and you get aroused," Natalie teased him, gasping just a little as he flicked one of her nipples with his thumb. She wiggled out of his tight grasp and handed him the shampoo. "Wash my hair."

Tony held the bottle in his hand, watched as she turned away from her. He licked his lips, tasted the remains of soap there and grinned. "The back side of you is just as lovely."

Natalie squirmed a little and looked over her shoulder at him. "Tony. Wash my hair."

"As you wish, darling."

It felt good, his hands massaging her scalp, his firm body pressed so tightly into hers that he could have taken her from behind if she commanded it. As he scrubbed the grease from her tresses, he pressed his lips just beneath her ear, whispering, "You're beautiful, Natalie, quite possibly the most beautiful woman I've ever been with."

She smiled as he finished washing her hair, letting the water wash over it and rinse it. She grabbed his hands and guided them up to her breasts and placed them there. "Do you say that to all women you shower with?"

He grunted while he played with her breasts, really getting to explore them this time. He kissed her again behind her ear, this time grabbing her lobe between his teeth and giving a gentle tug. She squirmed against him again, parting her legs slightly to allow him to explore her own arousal. The water was starting to feel cold against their hot skin, Tony lowered his face and burrowed it into her the soft flesh of her shoulder.

Natalie arched against him, throwing her head back in pleasure as his fingers found her center once again and began to stroke, sending wave after wave of ecstasy through her body. She forgot where she was but not who she was with. Tony's touch was gentle but filled with electricity that sent her over the edge, leaving her gasping for air as he kissed her shoulder blades, removing his fingers from her body and rubbing her arms.

Tony caressed her, reveling in the feel of her climaxing against his fingers but it wasn't going to be enough. Slowly and sensually he moved his hands down her body, hooked her waist and turned her to face him. Burying his hands in her hair, he pulled her towards him, searing her mouth with a kiss. If this was the only night she ever gave him, he wanted to engrain everything about her in his memory. How she smelled and tasted… and he couldn't wait any longer for how she felt around him. Ever so carefully he lifted her, hooking her legs around his waist.

"I need you, Natalie," he gasped, his lips still inches from hers.

"Then take me, Anthony," she sighed, her breath hot against his mouth.

He felt a jolt of electricity run through his body and he braced her against him by wrapping his arms underneath her butt. Locking his mouth with hers, with one slow, powerful thrust, entered her. He moaned, loudly, against her lips letting the joy of finally being joined with her so intimately wash over him. She was perfect… he was certain he had never been with another woman who he fit so wonderfully…

She titled her head back and let out a breathy, pleasurable sigh. Of course she had fantasied about what it was like to be with him, but this… oh this was so much better than a hot, sexy little fantasy… since in reality he was far from little…

Tony swept his tongue all over her mouth, tasting her and he slowly began to move, settling them into a steady rhythm. "Oh God, Natalie... waited so... so long...for this."

Natalie sighed in return, her voice gravelly with passion as she answered, "It was well worth the wait."

Falling into silence, only their heavy breathing and occasional moans of pleasure could be heard while their bodies moved faster in their erotic dance. The shower water ran cold over them but neither of them were even paying any attention to it. They were lost in the intensity of this encounter that they both had been fantasizing about for a long time now.

She hugged her arms around his neck tightly, lowering her forehead to rest against his while she bucked her hips against him to match his thrusts. She never pictured their first time having sex in a shower… but now that it was happening she couldn't picturing it happening any other way. It was hot and raw and intimate… and she was spiraling over the edge with a cry of his name and it didn't take him long to follow her.

Gasping for air, Tony smiled, "Thank God we weren't on duty until tomorrow morning."

"It would have been terribly hard to wait until we got back to D.C," Natalie replied, panting, heart racing.

"Oh, it was already incredibly hard," he quipped, waggling his eyebrows.

She laughed, huskily and then shivered now that her body was cooling. He gently separated their bodies, and with his arms still around her he shut the water off. He picked her up and stepped out of the shower, setting her down on the tile floor. He grinned at her and kissed her, softly, as he covered himself up with a towel, then he wrapped her in a fluffy, cream-colored robe and then making sure she was dry and warm, carried her back into the bedroom. He set her down at the foot of bed and turned down the covers. "Mmmm, who knew that the turn down service was so sexy here?"

Tony glanced at her with a cocky grin. "Is there anything else I can do for you, miss?"

Natalie twirled a damp lock of hair around her finger. "Lose the towel and get into the bed."

"On one condition."

"What condition is that?"

"You lose the robe and join me."

Her laughter filled the hotel room as he dropped his towel and chased after her, pulling her robe off and then picking her up and tossing her onto the bed. Tony crawled into the bed with Natalie, hungrily kissing her while he wrapped her into his arms. It was still hours before they had to be at the embassy to pick up their witness and he planned on spending as many of those hours making love to her.

With McGee out of commission for several weeks while he recovered, Vance had reassigned Stan Burley temporarily to help Gibbs while Tony and Natalie were in Paris.

Stan could tell that his old boss had changed quite a bit since the last time he had seen him which was almost seven years ago now. Gibbs seemed a little bit more laid back, more willing to work with the agent now than he had been years ago when Stan had been his SFA.

He had spent the flight getting to know the members of Gibbs team that Stan had not met. Tim McGee seemed like an upstanding guy, smart, computer savvy. Someone that Gibbs probably needed around because the old marine was technology challenged. Stan had strengthened those skills over the years but he still wouldn't consider himself someone that could go hacking into accounts… not someone like McGee. Natalie Callahan was a lot like Tony—former detective turned NCIS agent—but her degree in criminology, as well as psychology forensics made her a formidable profiler.

Gibbs didn't seem happy that Vance had sent Tony and Natalie to Paris to pick up their witness. Stan knew that the blubbering about Tony having a concussion wasn't the real reason, he might not have been on the former marine's team for a long time but even Stan knew when Gibbs was worried about Rule 12 being broken. Maybe it already had… if one listened to the rumors floating around NCIS…

"Burley, let's go," Gibbs snapped, blowing through the bullpen with a cup of coffee in hand.

"Where we going?" Burley asked, grabbing his gear up and following behind Gibbs.

"Georgetown," Gibbs replied stepping into the elevator. "Seems a marine surprised his maid by dying in the bathtub."

Burley furrowed his brow. "A marine can afford a place in Georgetown and a maid?"

Gibbs chuckled, before sipping his coffee. "Guess that's one of the things we need to find out, Burley."
