1. Chapter 1

Disclaimer: I do not own NCIS or its characters. I just merely borrow them for my own devious pleasure.

Hey guys! So I'm back with a new story. I've been working on a fairly long, multi-chapter story, but this one kind of hit me and I felt I needed to run with it. However, it's only a quickie, probably will only be like three parts. Warning: contains male-on-male action, some violence, and a bit of rape, so if it's not your thing, don't read it. Otherwise, enjoy! (:

~~~~~NCIS~~~~~

As Tony walked through the door to his home, he couldn't help but drag his feet and groan in exhaustion, though not too loud; he didn't want to wake his partner. He looked at his watch. Just after 2 in the morning, and there were no lights on anywhere in the house. His lover had to be asleep, right? Either way, Tony silently shrugged off his coat, which was damp from the snow that had just recently started to fall again, and peeled off his shoes. His feet ached, his head throbbed, and he still felt the chill from being out in the snow. But despite the pain, the babysitting had been worth it. His skills with kids had vastly improved since Palmer and Breena had given birth to their twins; he didn't feel afraid of them anymore and actually liked spending time with them. Tony smiled fondly as he thought about his adopted niece and nephew as he climbed the stairs to the bedroom.

The door was left slightly ajar. Good. He's asleep. Tony thought affectionately of his partner. It had taken him months to get his lover on what was considered a normal sleeping schedule. He quickly removed his cold, damp clothes in exchange for some warm flannel PJ pants. He didn't bother with a shirt; he knew he could just snuggle up close to the sleeping body next to him and his chill would fly the coop. And that's what he did. As Tony climbed into bed, shimmied close to his lover's side, and draped an arm over his stomach, Tony felt warmer already.

Then a quiet groan came from the other man. "Tony?"

Tony chuckled, "Who else would it be?"

"Bradley Cooper?"

Tony knew his lover had a not-so-secret crush on the Hangover star. "Hey!" Tony gasped faux-offendly. He looked to his lover's face and saw one blue eye looking back at him full of mischief. He stuck his tongue out and pouted, "You sayin' you'd rather Bradley Cooper be in your bed Gibbs?"

Both blue eyes looked at him as Gibbs shook his head, "You're much hotter than he is Tone. And much better at pleasing me in bed." Then leaned forward to press a gentle kiss on Tony's lips.

Tony sighed into the kiss before pulling away, "Good. I'm glad you think so."

Gibbs chuckled and relaxed, wrapping his arms around Tony and pulling him closer. "So how are Ducky Jr. and Arianna?"

"Little pains-in-the-ass," Tony said affectionately of their niece and nephew, "They gave me a run for my money today."

"Let me guess. Snowball fight against Uncle Tony?"

"Yup! And they won too. Ducky Jr. really has an arm on him. And Arianna is just so smart and sneaky. I didn't stand a chance." Tony laughed. "How was the meeting with the Director and SecNav?"

"Boring."

Tony smiled. Typical that his lover could say so much with just one word. Tony could tell that not only was the meeting long and boring, but something had happened to put Gibbs a little on edge. "Wanna talk about it?"

Gibbs groaned; he knew Tony wasn't going to like what he was going to say, "We decided on the new team…"

Tony looked up at the grey-haired man with a raised eyebrow. He could tell Gibbs was stalling, but he had to know. It had been a tragic day when Agent Balboa and two of his team hadn't come back to headquarters two weeks ago. Agent Balboa and Agent Ritter had been killed while chasing a drug lord in Mexico. Agent Martinez was still in the hospital, recovering from his near-fatal injuries. Balboa managed to take the drug lord down with him, but it would be a much sweeter victory knowing that the threat was over instead of knowing that someone else would step up to take his place.

Then of course came the difficult part, finding people to make a whole new team. SecNav and Vance had called Gibbs in, knowing that he would help pick the best men or women for the job. Ducky too had been asked to stay and lend a psychological evaluation on the candidates' files. The four of them had spent nearly all of the previous day in Vance's office, deciding who should be called to form a new team. That's why Tony had had to go babysitting alone. "So who did you guys pick?"

Gibbs ran a hand over his face, "One probie from the F.B.I., Agent Justine Brenner. Agent Dorneget; he'll be the second probie, though outranking Brenner. And two partners from the NCIS office in Brazil. They've been equals for years, so Vance wants to give each of them the chance to become the team leader; the other will become Senior Field Agent."

In the following silence, Tony waited. Finally, he grew impatient, "Who are they?"

Gibbs looked back at Tony, his eyes showing a mixture of worry, unease, and anger. "Agents Austin Dwyer and Christian Shaw, the latter being … an ex-fling."

Tony sat up in shock and anger, "He's a what?"

Gibbs sat up too, "Tony. I tried to tell them I didn't want an ex here but they said he and Agent Dwyer are the best down there. They really want them both here because they could get another team with chemistry like ours has."

"Well how did you two get together? How far did it go? How did you leave it?" Tony felt bad for pounding his lover of nearly a year with all the questions, but he needed to know.

"We met in the Core. Mostly just making out and hand and blow-jobs; once we fucked. But then I was deployed to Colombia, and I broke it off for good. He wasn't happy, but he understood."

"You told me when we first made love that you had never done it with another guy before!" Tony was furious.

Gibbs looked away, "No I said I'd never bottomed before."

"Okay. I guess you're right about that one… But you're saying you topped him?"

Gibbs nodded before looking back up at him, "Never did want to be bottomed 'til you Tone."

Tony groaned, "Gibbs." He wanted so badly to be mad at Gibbs, for not telling him about this Christian guy and for letting this happen, but as Gibbs said that and looked at him like that, like a sad, little puppy that knew he'd done someone wrong and was sorry for it and didn't want to get yelled at or kicked, he just couldn't stay mad. He sighed as his anger died, "What did you tell them?"

"That Chris is an ex of mine and I didn't feel comfortable with him being here. Nearly threw a fit of course."

"But it didn't work," Tony finished for him. He fell back on to the bed with exasperation. Vance and Ducky knew about Tony and Gibbs, everyone that was important to them did. Why would Vance allow Gibbs' ex and current boyfriends to be in the same building? He was supposed to be on their side! Tony growled to himself and ran a hand over his face.

"I'm sorry baby," Gibbs said in a quiet voice. He hated upsetting Tony like this.

Tony looked up into the blue eyes and saw the amount of concern there. He smiled gently, the last of his anger at Gibbs dying with the use of his favorite pet name, "It's okay. You tried. It's not your fault Vance can be a jerk sometimes. I swear the guy just like to mess with us to see how far we'll go. Maybe he just wakes up on some days and decides, 'I haven't messed with Gibbs and DiNozzo lately; I think today would be a good day to-"

Gibbs effectively shut the younger man up by covering his lips with his own in a deep, searing kiss. It was meant to show Tony that HE was the only one for Gibbs now and that Chris would not come between them. When Gibbs pulled their lips apart, they were both panting. "I promise Tony," Gibbs whispered in Tony's ear, "We will get through this."

Tony nodded, the kiss leaving him speechless. Then Gibbs fell back on the bed, pulling Tony over so that he could drape over the older man's body and rest his head on the soft grey hairs of his chest. When they were both settled comfortably under the blankets, Gibbs pressed a kiss to Tony's head, "Love you Tony."

Tony sighed, "Love you too Gibbs."

It didn't take long after that for both men to fall asleep.

~~~~~NCIS~~~~~

The next day, because they weren't called out on a case, Team Gibbs watched as the squadroom was turned upside down with boxes and rearranged desks. The new team was going where EJ Barret's team had gone. As a way to appease Gibbs and Tony though, Vance made sure that a row of single desks where between the two teams. Vance had seen what Gibbs had been like when EJ had been just on the other side of the thin bulletin-board barrier, and, what with Chris being Gibbs' ex, he couldn't afford to have them be that close to each other.

Gibbs was waiting anxiously for something, anything to happen. He knew there would be some kind of outburst from Tony; his younger lover kept looking over where Chris's team would be with this scowl on his face. McGee and Ziva were watching Tony, waiting to see what would happen. Gibbs had filled them all in about Chris. He and Tony were passed keeping anything from them, except for more personal details like bedside manners. Now, they were all waiting to see what would happen.

Dorneget had been hanging around for a while now. He got himself all settled at his desk, with a proud smile on his face for finally getting his chance to be on a team. Gibbs had recommended him and Vance had agreed that he deserved to be on a team. Soon after lunchtime, the FBI probie Justine Brenner showed up. She was 29 years old, very young for both the FBI and NCIS, but she had computer skills that rivaled McGee's, which made her very valuable. She was a tall women with long, wildly curly red hair and unique, amber-colored eyes. She was dressed simply in a pair of black jeans and a purple shirt with a black vest over it. Gibbs had to admit she was very pretty and didn't seem at all like the computer geek type. As she introduced herself around, Gibbs sized her up. She seemed very confident and willing to put up with the challenge of being on a team of men and having to prove herself. He liked that about her, but would wait to pass judgment when he heard of how she did in the field. When she got to his team, she confidently faced Gibbs.

"I've heard much about you Special Agent Gibbs," she looked him up and down. Then smirked up at him, "You don't seem as bad as Fornell made you out to be."

"Oh really?" He cocked on eyebrow and chuckled, not really knowing what else to say to that. She continued on, shaking Tony and Ziva's hands as they warmly welcomed her. Then she made it to McGee. Gibbs could see the instant spark between the two of them, and inwardly thought 'Oh boy…' He, Tony, and Ziva all looked at each other with knowing looks, all thinking the same thing.

Finally, the moment they had all been waiting for arrived. The elevator dinged and out stepped the two men, Austin and Christian. Austin was about Tony's age, height, and built, if maybe a little slimmer. He had sandy blonde hair and brown eyes. Gibbs would never admit it aloud but the new agent was rather good-looking as well, almost like he belonged in a modeling agency instead of a federal one. Christian, Gibbs noticed looked relatively the same from the last time they saw each other, just obviously older. His head that had been peaking with shaggy, brown hair was now bald. His long face trophied one of those mustache-beard things that covered around his mouth and chin, the black hair graying a little bit with age. He was as tall as he'd been back then, but he seemed thicker built now, still with muscled arms but with a bit of a gut. His brown eyes still reminded Gibbs of milk chocolate. In Gibbs' opinion, he'd definitely aged well.

As if reading his thoughts, Tony growled and stood up, coming to stand not two inches away from Gibb's side. Out of the corner of his eye, he saw McGee and Ziva share an "oh shit" look. Then they too stood, ready to mediate should Tony try to tackle Chris. Gibbs held his breath as he saw Chris look around the room before his eyes landed on him.

"Holy shit!" a huge, happily-surprised smile lit Chris' face, "Leroy Jethro Gibbs that you?"

Gibbs plastered a fake smile on his face and raised his hand, "Hey Chris."

Tony stiffened even more beside him as the bald man dropped his box and came rushing over to hug Gibbs. As their bodies contacted, Tony narrowed his eyes. As Gibbs lifted his arms to return the hug and pat Chris on the back, Tony growled.

Finally, the bald man pulled back and looked Gibbs up and down appraisingly. Then smiled at him, "No one told me you worked here! You look good!" Tony growled again. "Civilian life's been treatin' you well by the looks of it. Though your hair is greyer than I remember; it used to be darker. Though I've lost all mine so I guess you wouldn't be complaining." The man chuckled then his eyes wondered from Ziva to McGee and finally to Tony. His eyes lingered on Tony, perhaps catching the not-so-welcoming glare, before going back to Gibbs. "This your team?"

Gibbs nodded but thankfully Ziva stepped forward with a friendly smile and said, "Ziva David. You must be Christian Shaw."

"Call me Chris madame," he smiled sweetly at her as he shook her hand, "David huh? Is that Israeli?"

She smiled wider, "Yes. Good catch. Formally of Mossad, now an official American citizen and full-time Special Agent." She said it with such pride that Gibbs couldn't help but smile with pride as well.

"Well I'm sure you've had lots to bring and teach to Jethro here," he turned to wink at Gibbs, causing Tony to move an inch closer to Gibbs. Chris turned back to McGee as the younger man stepped next to Ziva.

"Timothy McGee. Welcome to D.C." McGee wanted to be hostile to the man for bringing the possibility of a storm to the team, but it just wasn't in his nature, especially not with the older man seeming so friendly and all. The two men shook hands and Chris thanked him for the welcome.

Then it was Tony's turn. In typical Tony fashion, he put on his mask, a huge, fake smile, a straight back, and a welcoming air. He stuck out his hand, "Anthony DiNozzo sir."

Chris shook his hand, "Ew. Don't call me sir. Reminds me of my father."

"Alright. You can just call me Tony." He let go of the older man's hand only to step closer, blocking him from Gibbs, "So has anyone offered to give you and your partner a tour yet? Because, as Gibbs' right hand man for over ten years now, I can assure you that not many people know this building more than I do."

Gibbs couldn't help but chuckle to himself at Tony's not-so-subtle way of keeping Chris away from Gibbs. Chris tried side-stepping around Tony but the younger man stepped with him. Chris just smiled, "Not yet. Vance told us to get settled in before getting the grand tour."

"Oh well then let me show you to your new desk." He draped an arm over Chris' shoulder and started to pull him away. Chris had no choice but to go with him.

McGee and Ziva stepped to each side of Gibbs and watched them go. "This isn't going to end well for someone Boss," McGee said quietly.

"Gibbs what do you want us to do about Tony?" Ziva asked just as quietly.

Gibbs watched Tony and Chris for a few more seconds. Tony doing his best at acting friendly and conversational; Chris looking like he wanted Tony to leave him alone. Tim and Ziva were right; this was not going to end well. Though why Tony decided to be so protective all of a sudden, he had no idea. Of course, Gibbs had never really been hit on or oogled before, nor had he really been around any of his ex-anythings since he and Tony got together, just Dianne once when she came to drop Emily off with Fornell. Tony hadn't shown any signs of jealousy then, but maybe that was because he knew Gibbs didn't have any feelings for Dianne whatsoever, and that she was happily married again. He thought about Ziva's question. He had never been in this situation before; he had no idea what to do.

Finally, he couldn't stay in the squadroom anymore. As he turned to the elevator, he said over his shoulder, "Just make sure he doesn't kill Chris. I'll be down with Ducky if you need me." He walked to the doors and pressed the button.

"Agent Gibbs?" a voice said behind him. Gibbs turned around to see the hesitantly smiling face of Austin Dwyer.

Gibbs dipped his head, "Yah. You're Austin?"

The younger man smiled wider, "Yah. That's me. Just wanted to come meet the infamous Leroy Jethro Gibbs. I've heard much about you, and not just from Chris. You're like a legend."

Gibbs couldn't help but chuckle, "Yah well, most say I'm just a bastard; legend is not one I've heard before." Behind him the elevator dinged and the doors opened.

"Mind if I come with you?"

Gibbs shrugged, "Goin' down to autopsy."

Austin followed him in, "I actually was hoping to meet Abby Scuito. After being a field agent, forensics was my next passion. I'm a huge fan of her work and wanted to see the mastermind behind it all."

Gibbs smiled and pressed the buttons for the autopsy and forensics lab floors. The doors closed and they started moving. After a moment of silence, Austin spoke nervously, "You've known Chris for a while now right?"

Gibbs nodded.

"Well, he's been my partner since I joined NCIS. About ten years… He talks about you a lot…"

Gibbs turned to him with a raised eyebrow. But then the doors opened to autopsy, and Gibbs had no choice but to get out. As the doors closed, Gibbs realized just how much he needed to talk to Ducky. The doors to autopsy swooshed open. Ducky and Palmer both looked up from the body they were working on, but one look in Gibbs troubled eyes and Ducky knew he couldn't wait long.

"Be right with you Jethro; Mister Palmer and I are almost done here."

"Take your time Duck. Just need to ask you something."

"Okay. Let's hear it."

Normally, Gibbs would want to have this talk with Ducky privately, but over the last two years or so, Gibbs would talk in front of Palmer every so often, especially if it involved Tony. When the young M.E.'s assistant wasn't so nervous, he could come up with good advice and knowing Tony as well as he did, it made the advice that much more viable.

"Chris is here."

"Oh dear… When?"

"He just got here maybe twenty minutes ago… Tony's distracting him… from being with me."

"He's jealous?" Palmer gasped. "He's only ever been jealous once and not very at that."

Gibbs knew about the time Tony had gone to the hospital to see Jeanne and she was being massaged by another guy. But Palmer was right, once Tony found out the other guy was gay, he wasn't bothered anymore. "It's different this time," he agreed.

"And you're worried Tony might say or do something he'll regret," Ducky could almost always read him like a book. He was almost as good as Tony at it.

"Or that might pissed Vance off and get him fired. Or that Chris will fight back. If he stills wants me, he'll use his marine training. Tony might get hurt." Gibbs didn't often show his worry to others, but he knew he could with his NCIS family.

"Tony can spar too Gibbs; he can handle his own. But I understand your concerns. Maybe you should have a talk with Chris. If it so happens that he doesn't still want you, then you can tell that to Tony and all will be well."

"And what if Chris does still want me Ducky?"

"Then maybe you can calmly explain to him how you feel about him and about our young Anthony. Show where your loyalties lie so to speak."

Gibbs fell silent, thinking as Ducky and Palmer continued their dissecting. He didn't think he could just go up to Chris and ask whether he still had feeling for him or not. He also wasn't sure he could handle it if the other man said yes. But something had to be done before Tony took it upon himself to find that information out. "I'll think about it. Thanks." With that he turned and left autopsy. But instead of going back upstairs he pressed the button for Abby's lab.

When the doors opened, the music he heard wasn't as loud as he expected, and he heard two voices talking animatedly. He walked in to see Abby and Austin laughing as she showed him every single piece of equipment. His eyes widened as he saw how well they were getting on. Then Abby must've sensed him staring and turned to smile at him, "Hey Gibbs!"

He walked in, smiling at her, and kissed her on the cheek.

"Is that because you didn't bring me a Caf-Pow?"

He nodded his head.

"Ah well that's okay. Have you met Austin yet?"

"Mmhmm. He told me how much of a fan he is of your work."

The younger man blushed and looked away while Abby giggled, "I can tell. I haven't given such an in-depth tour in years!" She winked at Austin before looking back at Gibbs, "So what brings ya down here today Gibbs?"

Gibbs motioned with his head for them to go into the other room so he could talk privately. She nodded and said to Austin, "Be right back."

When they were behind the door, Gibbs said to Abby, "I may have to send Tony down here more often, so you're going to have to keep him busy when he comes."

Her brows furrowed in worry, "What's wrong?"

Gibbs sighed, "Tony is currently using all his skills to keep Chris away from me."

Abby eyes widened, "He's jealous? But that's only happened once!"

Gibbs nodded, "I know. But yes, it would seem that way."

"But why would he be jealous? It's so obvious that you're in love with him and no one else. You would never cheat on him. And you said Chris was your ex. Unless," she gasped, "Chris must still have feelings for you. Tony wouldn't be acting jealous unless he has a reason. And if he picked up on that, he would definitely have reason."

"He doesn't!"

Abby cocked an eyebrow and placed one hand on her hip, "Are you sure Gibbs? Like absolutely, positively, completely, 100 percent sure that Chris has no feelings for you?"

Gibbs stayed silent.

"I didn't think so," she trailed off as she thought for a moment. "Okay," she said finally, "you get back up there and make sure Tony hasn't attacked Chris. If you need to send him here, I'll keep him busy. You just go make sure he knows where your claims lie."

Gibbs nodded and placed another kiss on Abby's cheek, "Thank Abs."

Then he left quickly to go see what damage had been done upstairs.
