Thanks so much for the reviews! And now on with the last part!

Gibbs nodded curtly and said, "Okay. Follow me." He stood up and walked toward the back door of the house with determined strides, without looking back to see if Tony was following him.

He smiled at the typical Gibbs attitude and rushed to follow the older man inside the house and then upstairs, into the bedroom he had never seen during all the time he had spent at Jethro's home.

The furniture was all in wood and the dominant colours were blue and dark brown. It was strong, masculine and elegant without being pretentious.

Gibbs closed the door and stepped near him.

"May I resume kissing you?" he asked all gentlemanly, but with a hint of humour.

Tony smirked, "Of course you can."

The older man raised his hand and cupped Tony's nape. Jethro's fingers were tangling into his hair, slightly bending the younger man's head down to meet his lips. As before, the kiss started slow, with no pressure. It was like Gibbs was waiting for him to decide if and when to bring it to another level of intensity.

Feeling more confident this was actually going to work, Tony opened his lips to admit Gibbs' tongue, meeting and stroking it with the tip of his own.

Their ardour escalated quickly, and the kiss turned more passionate and demanding. When they separated, they were both breathless, their lips swollen and reddened.

"That was good…" Tony commented.

Gibbs just smiled and fingered the buttons of his shirt, a silent question in his eyes.

"Yeah," Tony breathed, as his own hands rose to attack his lover's t-shirt.

They both made quick work of their upper clothes, and soon their chests were bare to each other's gaze.

Tony hadn't seen Gibbs undressed in a long time and was taken aback by how good looking he was for a man in his mid-fifties. Gibbs had broad shoulders and was well made, his muscles defined in a lean kind of way. His chest was covered by fine grey hair that narrowed into a line that crossed his belly and disappeared into the waistband of his trousers. His stomach had softened a bit with age, but Tony's fingers twitched with the desire to caress it. The older man's skin was smooth, only marred here and there by scars, silent testimonies of all the perils Gibbs had encountered during his years as Marine and NCIS agent.

"You are gorgeous," Tony whispered, surprising himself.

"Really? I think you are more so," Gibbs said as he stepped closer, so that their chests pressed together as they kissed again, more passionately than before. Heat spread in Tony as he felt something else press against him—his lover's erection was digging into his thigh.

Tony moaned when Gibbs' hands slid down his back to briefly squeeze his ass. He broke the kiss and simply uttered, "Please."

The older man's long, nimble fingers went to Tony's zipper, opened it, and pulled the fabric down.

Tony felt no shame when his erection sprang free—he quite liked the way Gibbs was staring at it.

"You are hard…" the older man murmured with intent.

"Uh, well, yes," he replied, perplexed. Gibbs wasn't the kind of man to make such dumb comments.

Gibbs' eyes flashed as he said, "It means you do like sex, Tony. You just need it to be good sex- and I'll give it to you."

Tony's eyes widened in surprise. Overwhelmed as he had been by the fact he was going to make love with Gibbs, he hadn't realized how quickly he had become aroused. Usually it took much more than a few kisses to get him to be up for action…but not this time.

Gibbs smirked when he saw the understanding dawn on the younger man's face, then turned around and removed his sweat pants and boxers, folding them on the nearby chair, as Tony got rid of his footwear and lowered pants.

When Gibbs turned to face him again, Tony's heart skipped a beat.

Gibbs…Jethro was magnificent, all tanned skin and lean muscles, powerful and yet graceful.

His legs were strong and well shaped but for his left knee. Injured during an explosion in Kuwait back in 1991, it had occasionally bothered his former boss since then, but never so much to be a problem on the job. However, three years before, he had re-injured it when he had thrown himself in front of an approaching car to save a child from being hit. This time the damage had been extensive; the ligaments had been torn and the surgeons in Bethesda had had to reconstruct them. They also had to implant a ten centimetres long plate and several screws to fix the broken bones. It had taken Gibbs six months to return to walking without a limp, and even now, thirty months later, the knee still looked a bit swollen.

Tony shook his head to push away memory of the terror he had felt when he had seen Gibbs jump in front of the fast approaching car and concentrated on more pleasing things, such as his-soon-to-be-lover's cock. It was thick, probably thicker than his own, and very hard, arching toward the older man's belly.

He reached out to brush it, and it was Gibbs' turn to moan, very low and deep into his throat. The younger man found the sound very arousing.

"Let's get comfortable," Gibbs murmured and Tony nodded, moving to the bed.

They lay on the mattress, side by side, facing each other. They embraced, hands sliding around strong backs as the front of their bodies pressed together, and they kissed again.

Tony loved the feel of Gibbs against him. He was both hard and soft, the skin hot and pleasant to the touch, his burning erection causing a thrill when it brushed against his own aroused cock.

They kissed for long minutes, and then Gibbs pushed gently at Tony's shoulder, encouraging him to recline on his back.

"Let me know if I do something you don't like," he said, before he posed a line of kisses across his chest.

The younger man's "Yes" was lost in a moan when Gibbs' hot mouth engulfed one of his nipples, sucking on it delicately. Tony raised his arms, treading his fingers in his lover's silver hair as he pushed his head harder against his chest.

Gibbs worked Tony's nipples for a while, and then moved his mouth lower, leaving a damp trail of kisses and licks as he slid down across his abdomen.

By the time he reached his erection, the younger man was almost hyperventilating. He knew what Gibbs was about to do and his excitement increased to a dangerous degree. He just hoped he wouldn't explode at the first touch on his cock.

Gibbs looked for a moment at Tony's cock, as if he was trying to decide the best way to proceed, then he used his hand to steady the shaft, holding it up so he could gently lick its head.

Tony whimpered in delight. Some of his previous lovers had done this to him, but it was so much more erotic with Jethro.

Gibbs explored Tony's cock with his tongue, licking the vein on the underside and the slit at the tip. Then, when he thought he could take no more, his lover fit most of his erection into his warm mouth and sucked.

Tony moaned and clutched at the sheets, his knuckles turning white.

"Jethro," he panted, a plea and an encouragement.

Gibbs bent over him, pushing his hips to the mattress to prevent him from bucking too much, and kept on sucking him, adding the press of his tongue along the shaft to the suction. Unable to hold out any longer, Tony came with a yell, his orgasm intense.

When it was over, he slumped on the bed, exhausted. He panted, eyes closed as he tried to calm down his breathing. When he finally opened his eyes, he saw his lover's face hovering over his own.

He raised his still trembling arms and pulled the other man's head down for a kiss. He found it exciting to taste himself on Gibbs' lips and tongue; his other lovers had always pulled away before he came.

"That was good…" Tony murmured when the kiss ended.

"I'm glad you liked it," Gibbs answered, his voice a little breathy, his pupils so dilated the blue irises were almost invisible.

Tony suddenly remembered Gibbs still needed to come.

What would he want to do next? Tony tensed in concern. Would he expect reciprocation? And if so, would he be able to take him in his mouth and give him the same pleasure he had just experienced?

"Shh…don't worry so much," Gibbs soothed, running his hand up and down his arm. "I won't do anything you are uncomfortable with."

"Yes…but I want you to feel good too…"

"And I will…just trust me. Let me do all the work."

Tony nodded and watched curious as Gibbs stretched atop of him, using his elbows and knees to keep most of his weight off his body.

The older man guided his cock between Tony's thighs, and then used his hands to press them together and thrust once, tentatively.

"Is this okay, Tony?" he asked, breathlessly.

Tony nodded, sliding his hands along Gibbs' back as he tightened his legs as much as he could to provide the friction his lover needed.

Gibbs moaned in approval and thrust again and again, his movements gradually gaining speed and rhythm as his pre-come slickened the channel between Tony's thighs.

The younger man watched with avid eyes as Gibbs laboured over him, his movements as fluid as the tide of the sea, but hot as molten lava. He enjoyed how the older man's heated breath fanned gently across his collarbone, and the feel of his lover's well-muscled back flexing underneath his hands.

"Tony," Gibbs whispered, and closed his eyes. His body shuddered and then warm liquid spread between Tony's thighs, and his lover sagged against him.

Tony tightened his embrace around the older man's back and lay there, feeling more content than he ever had in bed with anyone sprawled across him. For a few moments he didn't even mind the sweaty, sticky weight, and when he did it only took a little nudge for Jethro to roll away.

After a while Gibbs sat up and looked down at him, "You all right?" he asked.

His slightly slurred voice made Tony smile. "Perfect. This was very nice…"

Gibbs grinned. "Ya think?" Then he sobered and nodded. "Yes, it was very nice indeed." He flopped back to recline on the mattress with a loud, contented sigh.

Tony closed his eyes, feeling boneless. He usually rushed to clean up and get dressed after sex, but today he just wanted to bask in the afterglow. What he had just experienced was fantastic. They seemed to be really compatible, both in and out of bed, and he wondered what the future would bring for them.

"I can hear the wheels turn in your head…" Gibbs grumbled, rolling onto his side as he raised his head with his elbow. "What is it?"

"Nothing…just wondering about what happens next."

Gibbs looked at him thoughtfully, "Whatever you want to happen. We can carry on as we have done for the past three years, just adding…more personal activities…to the list of things we do together or-"

"Or?"

"Or you can move in with me and we can really start spending our lives together."

"Isn't it a bit soon for that?" Tony asked, as his heart started beating faster. Living with Jethro as partners…it was such a mind-blowing idea…both scary and exciting…and so very appealing.

"As I see it, it's not that soon. In a way, we have been dating for the past three years, even if we weren't aware of it…" Gibbs replied his eyes intent as they stared at Tony.

The younger man thought back at the past three years. At the weekends spent at the marina helping Gibbs finish the new 'Kelly' and at the trips they had taken on the boat, with the older man trying, not too patiently, to teach him how to sail. The afternoons spent touring tool shops and wood stores, watching as Jethro chose what he needed to build the furniture for Abby's new house; their shopping trips for Christmas, when they had bounced ideas off each other as they looked for the right presents for their friends. At the football games they watched together and at their quiet dinners afterward. At their visits to Shannon and Kelly's graves and at the strange emotion Tony felt as he listened to Gibbs as he told him about them, because he knew he was the first person the older man had trusted with his most precious memories since his loved ones had died. At the evenings spent at his apartment, watching movies as Tony told Gibbs how Gary Cooper and James Stewart had been his best friends as he grew up, the son of two parents that couldn't find time to spare for their only child….

Even if they had spent less time together than Tony had with Elizabeth, they had learned about each other, they had understood each other and been there when one of them needed the other.

Tony's eyes widened: Jethro was right, they had been dating for years, and they had never realized it. He had been so busy keeping his mask up he had not seen what was straight in front of his nose, while Gibbs had probably kept a tight hold over himself in order not to reveal what he really felt for Tony.

They had been two idiots- but no more.

Now they knew what they had and Tony was not going to let it slip from his grasp.

He smiled up at Gibbs, who was still looking at him. "You're right, we've been dating and this is really the time to move our relationship to another level."

"Good. We'll start packing your stuff today—after we finish with the fence."

Tony smiled at the commanding tone. Gibbs would never change, and it was a good thing, because he liked the older man exactly how he was.

"So we're gonna live together… Can you imagine what people like Vance will say?"

Gibbs shrugged. "I don't really care. I've never minded what people said about me and in time you'll learn to do it too."

"Will you teach me?" Tony asked.

"Nope. This is something you can learn only on your own."

"But you'll teach me to love sex, huh?"

Gibbs smirked, and his blue eyes flashed. "You think I can teach you that?"

"Yes, I'm pretty sure you can. Knowing your determination and stubbornness, you'll teach me to like it, to love it, to crave it and then…"

"Then?" Gibbs prodded, tilting his head.

"Then you'll grow old and lose interest in it!" Tony completed, flashing a big, toothy, impudent grin at his lover, a moment before said lover head-slapped him.

"Shut up, DiNozzo!" Gibbs growled, glaring at him.

"Shutting up, B-"

The rest of Tony's line was muffled by Gibbs' lips as his mouth was captured in a hard kiss. He wrapped his arms around the older man's back and gave himself up to his lover's attentions, eager to start their second lesson at lovemaking.

THE END

.

A/N: Time ago I made some researches about gay sex and relationship and found a post on a forum where a gay man commented slash fiction. Among the many things he wrote, he said that in fan fiction stories there is a great, perhaps too great, insistence on anal sex. He said that perhaps it was due to the fact the writers are mostly females and that they were probably influenced by gay movies, which, as all p**n, don't give a true representation of what normally happens in a bedroom, but are more about transgression. Then he explained that a gay relationship is not synonymous of anal sex. Being in a gay relationship means to appreciate the male person as object of attraction and love, no matter how they are expressed. He then said many couples seldom or never practice anal sex but find other ways of lovemaking and went on explaining some of them.

Of course, because things are seldom black or white, another poster replied to the guy above telling him he was an idiot and that being in a relationship meant to fuck as rabbits and that slash fiction was too tame or too focused on feelings and emotions, while instead it's all about sex.

I guess these guys were both right and wrong, and that the truth is far more complex.

Anyway, that first post on the forum gave me the inspiration for Tony and Gibbs' preferences in this story. I hope you all enjoyed it! Let me know what you think and stay tuned for more Tibbs stories!
