Notes: So there's still a glitch with reviews. I've reported it, but I don't want to loose any readers by reposting, and I'm not sure that's even going to help. So thanks for the support guys it really means a lot to me so please don't take my lack of responses as I don't appreciate it.

She way laying in his bed next to him. She sighed happily when he kissed her forehead, and ran his fingers through her hair. These quiet moments they would share was what they both lived for. She smiled at him and his fingers ghosted her lips. She kissed them softly. Then he moved closer to brush his lips against hers. His hands were now travelling down her back. She stifled a moan, not wanting to get started all over again. As good as it all felt it could be a vicious circle.

"I don't have another round in me," she warned him.

"All right," he assured her, his hands going back to her hair.

She curled in close to him, somehow this felt even more intimate than what they had done only moments before. She was letting her guard down, letting herself feel. She had had her eyes closed for a long moment and opened them to see him smiling at her. She realised that this was just as intimate for him as it was for her from the way he was looking at her. He also liked how real these private moments felt. He had been a long time since he had a woman in his life he trusted so much.

Neither of them was ready to say anything out loud but they could both feel how powerful what they shared was. He had noticed that time they spent quietly laying in each other's arms more and more as time went on. There was something comforting about it, and he was scared to say anything about it. Instead he would cherish each silent, sweet moment. It felt good, but he knew that things were on the verge of changing whether they wanted it to or not.

He was happy that she would be closer, that they would be able to see each other for more than a few fleeting moments. There was something both amazing and terrifying about that realisation. Being so close could end up being the best thing for them or the worst, and they were both along for the ride. He wanted to be positive but they both knew how their histories had played out before. It would be even more difficult being under the microscope at work; everyone would be waiting for them to make a mistake and show more than they needed in order to their jobs.

"I've been thinking," he told told her.

"That must be why I smell smoke," she laughed.

He laughed. "I might need to invest in a helmet."

"How long does it take your brain to get back the blood after we have sex Tony?"

"Not as long as you think when you say no. Since you're going to be on the team I'll have to control myself around you. I know I won't be able to touch you, that's easy enough to keep in check, but I won't be able to help but look."

"That's very flattering Tony, but you're still not making any sense," she told him curling up to him.

"Every time Gibbs catches me he's gonna head slap me."

"That sounds like a you problem," she laughed.

He kissed her deeply. "I can make it a we problem in the morning," he reminded her running his hand down her stomach.

"If we both come in exhausted not having slept, you won't have to worry about any head slaps. He'll shoot us both."

He ran his finger through her hair. "You're right," he yawned. "I didn't really have it in me anyway."

She got out of the bed and picked up his shirt before she went into the bathroom to get ready to go to sleep. She was surprised by how much of her stuff had made their way into his bathroom; and how much it all looked like they belonged there. After she was done he went to brush his teeth as well. He pulled his boxers on before he went into the bathroom. When exited the bathroom he slipped off the shorts before getting back into the bed.

"I can hear you rolling your eyes at me," he joked.

"You're never going to change," she laughed.

"And you don't want me too. Night, Paula."

She yawned, "Good night Tony."

He pulled her closer and soon they both drifted to sleep. When she woke up the next morning she smiled when she smelled coffee brewing. There were so many small things that DiNozzo did for her that made her wonder if he wanted something more than the casual encounters they inevitably allowed themselves to fall into. She was still wearing his button down shirt when she went into the kitchen.

"Morning," he greeted. "I'm just about to take breakfast out of the oven, coffee's fresh."

"Thanks Tony," she murmured, covering a yawn. "If we keeping showing up to work together everyone will start talking."

"Let them talk. How about we make the most of this until you find yourself an apartment?"

She went over and kissed him softly, placing her hands on his chest. He kissed her back, wrapping his arms around her waist. She pulled away from him and stared up at him smiling. These were the moments they both cherished although neither would tell the other the truth. They sat down and enjoyed their breakfast together before they went in to work; which could change everything for them but they both knew it was the right choice.
