Abby's teasing did not stop there. Tony recalled her dirty jokes and flirtatious dialogue from before that night, but now that he knew how she really was in bed, he couldn't help but picture her "jokes" about habits in the bedroom as being fully true about her.

Their next case, one where a lost, amnesiac was found wandering the forest in the middle of winter after having been buried alive, only metastasized poor Tony's vivid daydreams of Abby when they found a missing key in the woods as well. Trying to figure out what the key unlocked, Abby jokingly suggested that the key might go to a Chastity belt.

"So I suppose you want me to find out which Chastity belt this opens." She asked Gibbs who just looked at her with a dumbfounded expression on his face.

"Do I look like Dinozzo to you?" He asked her.

"Not funny, Boss." Tony began. "Besides…I can open a Chastity belt." He responded to Gibbs though he kept his eyes on Abby while he said it, waiting for a reaction from her.

"You should see mine. Mine's awesome. It's 18th century French." Abby replied as if to compete with Tony on the subject.

He was impressed with himself at his ability to keep his mouth closed while she said that, his mind immediately trying to picture her wearing one and all of the ways he would try to remove it. "You have a Chastity belt?" He asked her, tilting his head in a way as if to try and get the woman to look at him and when she did, their locked eyes made him feel a wave of heat travel through every vein, threatening to move down between his legs, but Gibbs' voice thankfully, stopped that feeling immediately.

"So much more information than I needed to know about Abby." Gibbs interrupted their moment with a tone of annoyance.

Tony instantly remembered Rule 12 and that talking about Abby this way in front of Gibbs, his favorite, his work-daughter, was a terrible-terrible idea. But Tony really wanted to see her in a Chastity belt now. His eyes moving up and down her body as he tried to picture it, ignoring the other two's voices for a moment as they kept talking about work and Tony wished he was somewhere else. With her.

Soon Kate entered the lab with news about the woman whose memory had still not returned and Tony was finally snapped out of his thoughts. He started to ask himself if Abby were playing some sick game with him. Like a snake charmer enjoying the sight of the snake squirm whenever they wanted it to.

He left the lab with Kate and Gibbs, boarding the elevator as Kate squinted her eyes at the man beside her. "Tony, you okay?" She asked him. "You were pretty quiet in there. That's not like you."

"Just thinking." He told her.

"About what? Agent Cassidy?" She half-joked, knowing that they'd only had one dinner date since they all returned from Guantanamo Bay, but she never heard anything about her since.

"No. That didn't work out." Tony admitted. "Once her old boyfriend found out she was back in the states, that was it for us."

"Oh." Kate nodded, looking ahead at the elevator doors again.

"Besides…I can't be tied down." Tony said as the doors opened and Gibbs exited the elevator first, followed by Tony who walked over to his desk to grab his gear, Kate following.

Later that night, Kate allowed the Jane Doe they were trying to help to stay at her place and Tony made note of that, considering Kate hardly knew this woman and she always turned Tony down for a sleep over.

The next morning, Gibbs and Dinozzo walked into Abby's lab for some more information on the key they had found.

"Hey, guys." Abby smiled at both men from the tall chair at her lab computer. "What'd I miss?"

"Kate willing to give her bedroom to Jane Doe, but not me." Tony didn't mean to say that out loud in front of Gibbs.

Abby smirked up at him beside her. "Mm, shocking." She said with a sarcastic tone and a glint in her eyes.

Gibbs quickly brought Abby's attention back to the key, as Tony wondered what Abby's tone meant when she said that. He started to feel paranoid that maybe his moves in the bedroom hadn't satisfied her as much as he thought they had. What kind of a statement was that?

He ignored his thoughts for now as he looked down at the key they were still trying to figure out and his great eyes caught something. What looked to be the smallest scratch turned out to be a huge clue in the case and Abby was impressed at his attention to detail.

"How does somebody etch letters that small?" Gibbs asked, moving closer to the projected screen in Abby's lab to look at the magnified image of the key where the words 'The Apartment' were branded into the key.

"Micro-laser." Abby explained, telling Gibbs that the same tool that was probably used to etch that into the key is the tool that is used to put serial numbers on diamonds and whoever had that key was probably testing it out. "Maybe somebody was playing with the hotel's new toy. Like when photocopiers first came out and people were copying everything from C-notes to their butts."

Tony looked at her with a suspicious smirk. "You sat your naked-butt on a photocopier, didn't you, Abby?" He asked, knowing by now that any reference she made to something was most likely something she experienced firsthand.

She looked up at him like he should know this by now. "Yup."

"Let me know when you find the hotel that has a micro-laser, Abs." Gibbs said as he turned and left her lab.

Once Tony saw the elevator doors close with Gibbs inside it, he looked back at Abby. "Is there anything you haven't done?" He asked her.

"Probably not." She admitted, starting to type on her computer again to search for the hotels.

"We should play Truth or Drink some time then." He joked, lifting up the key from under the microscope to fiddle with it in his fingers.

"What? You think you can beat me?" Abby asked while still looking at her computer screen.

"No. I'm beginning to think NO ONE can beat you." He admitted.

"Are you getting jealous again?" She asked him as she stood up and walked around him, heading into her office.

Tony followed her without answering her question. "How about tonight?"

"Tonight?"

"Yeah. I can come over to your place." He suggested. "I'd offer my place up, but my boiler is still out."

"Why would we do that?"

"To have fun. Remember? What are friends for?" He repeated her own words back to her.

"Drinking buddies." She repeated his words back to him and chuckled before turning around to face him.

He stopped following her in the doorway of her office as his eyes fell to the shirt she had on beneath her labcoat. It wasn't anything too revealing. Just a simple black t-shirt. But it was only now that Tony could see the very thin strings that were crossed over the open slit above her cleavage. Crossed to form diamonds over her skin and Tony wished it WAS more revealing. But the fact that it wasn't seemed even more sexy to him. It was more of a tease. And the black choker she wore only reminded him of his hand around her throat the night that they fucked.

His eyes fell to her lower torso as he pictured her wearing the Chastity belt under her clothes today just for him. He knew that was probably not true. But he wanted it to be.

"Why don't you ever wear your hair down here?" He asked her.

"I don't wear my hair down anywhere but at home." She told him.

"Why? It looks nice when it's down."

"It doesn't look nice when it's up?" She asked him just to make him squirm. That snake charmer thing again. Tony began to wonder if she KNEW she was doing it.

"Oh, it does." He told her, pushing himself off the frame of the door and stepping closer to her, but not too close. "I love your little pigtails…I was just saying." He then smiled more. "Am I the only one in this building to have ever seen your hair down, Abs?" He liked the idea of that.

"No." She told him truthfully. "Do you wish you were?"

"No." He lied. "Just curious."

"Something tells me that you are obsessed with me, Anthony Dinozzo." Abby said, though it wasn't truly how she felt. She knew Tony would never obsess over anyone besides himself. But she thought this game with him was fun.

"Obsessed with you? No." He softly chuckled. "Obsessed with your body…" He looked her up and down again, this time with her knowledge. "It's too bad you have a boyfriend."

"Boyfriend?" She softly laughed. "Tim is not my boyfriend."

"He's not?" Tony perked up with hope.

"No. He knows that we are non-exclusive right now." Tony opened his mouth to speak but Abby put her forefinger up against his lips to shush him before he could speak. "However….He and I ARE moving in that direction and I don't want to mess it up."

"But what if-" Tony's words were mumbled as Abby's finger was still against his lips and he gently took her wrist to pull her hand away from his mouth before he continued. "...what if we just did it…ONE more time?" He suggested. "Just to get it out of our system…I mean, come on. Our sexual tension has only grown worse since we-"

Abby began to laugh. "Our sexual tension? Come on, Tony."

"You can't tell me you've been giving me eyes and wrapping your arms around me from behind to type at my computer for no reason. And the gunpowder perfume? You can't say that was to impress McGee." He laughed a bit. "I'm the one with the gun."

"Maybe….the gunpowder perfume was to impress somebody else entirely." She told him, resting her hands on her own lower back by her hips.

"Who? Gibbs?" Tony laughed at himself.

"No. Kate." She smirked.

"Oh, come on. You mean to tell me-" He stopped what he was going to say when he saw how serious Abby was. "Oh, dear god." He almost moaned. Now, was he not only picturing Abby in a Chastity belt….but with Kate.

Abby shrugged. "I get what you see in her." She admitted. "But you have more of a chance with her than I do."

"What makes you think that?" He smirked, feeling cocky for a moment before Abby answered.

"Because I'm a woman. And I'm pretty sure Kate's only into pickles….if you get me." Abby went around him to sit at her desk in the office.

Tony stood across from her desk, leaning his hands down on the flat surface between them. "Come on. At least think about it. Maybe I wasn't on my A game that night. But I promise…if you give me a second chance…"

"Wait. What are you talking about?" She asked, putting her feet up on the corner of her desk and crossing her ankles. "Tony….you were…..awesome that night. Not to give you a big head…" She pointed out. "...But it was great."

"Well…earlier you said that you weren't shocked that Kate still doesn't want me."

"That's because of how annoying you are." She laughed again, starting to swivel in her chair a bit with her feet still up on the desk. "And…Maybe I was a little jealous." She admitted.

"YOU? Were jealous?" He stood up straight with confidence again.

"Yes….I will admit that I miss that cock of yours." She said nonchalantly as her eyes looked between his legs and she smirked more.

"Really?" Tony managed to choke out as he felt that heatwave threatening to move between his legs again. "You…think about me?"

She nodded, her eyes stuck between his legs. "Mhm." She admitted and bit her bottom lip.

"Then why won't you fuck me again?" He asked her.

"I never said that I wouldn't." Her eyes finally looked back up into his eyes and she bit her lip harder with a wink before Gibbs returned right on time and her printer began to spit out papers with the names of the correct hotels on them.
