'thinking'

"talking"

Sasuke had no more time to waste for fantasies, with Naruto's legs still hooked over his shoulders he leaned forward to kiss Naruto's lips gently to apologize for the pain he was going to cause him. "This will hurt some Naruto, I'm sorry it is not my intention to do so. I promise the pain won't last though." He said against Naruto's lips as he slowly entered his body.

Sasuke took his time, he was a well-trained shinobi after all and had a lot of control. He allowed Naruto all the time he needed to adjust, going bit by bit slowly pressing forward, always waiting until Naruto's muscles stopped contracting and he relaxed, then he would begin again advancing this way until he was completely within him. The whole time he had been stroking Naruto gently not only to take his attention away from what he was doing but to also lessen any pain. Sasuke kept himself under tight control as he shifted himself searching out the bundle of nerves he knew laid within. He needed to find them not only to make things pleasurable for Naruto but also the temporary opening to the female organs that were now within the blonde's body were located there. If he was going to impregnate his friend that was the spot he needed to be at.

Naruto's jerk and gasp alerted him when he had found them. Smirking he angled himself so he would rub right along them as he began the process that would lead him to conceive a child with Naruto.

Sasuke hadn't realized the sensations he would be experiencing. Of course there had been some physical pleasure for himself with the test subjects, but he had not counted on the flood of emotions he felt since the one under him wasn't just some nameless man who would help with his research. This was Naruto, the one who would help him restore his clan. The emotional control he had always prided himself on was soon gone, knowing he could not fight what he felt he simply accepted them as proof that he had been right in picking Naruto. He found himself praying that when he faced his brother he would not only succeed in avenging his clan but would live to return so that he could further analyze the connecting he felt with him.

Sasuke made sure he helped Naruto find release before him, it was the least he could do for him after all, he found himself falling over the edge into bliss soon after from the sudden grip Naruto's body had on his member, the spasms proved to be his undoing. He was happy to find Naruto's body seemed eager to have his seed as it milked him dry. All Sasuke wanted to do at that moment was lay down on top of Naruto and hold him till his vision cleared. But he knew if he was going to insure Naruto conceived he had to hold him up.

Blinking to force his vision to come back into focus he watched the Kyuubi's seal on his stomach flare up. Waiting a few minutes Sasuke pulled his chakra into his hand to allow him to manipulate his seed to the place where the egg that already possessed Naruto's DNA to mix.

Watching the Kyuubi seal Sasuke was thankful when it began to fade from view, that was the sign he'd been waiting for that everything was going according to plan.

Using his medical training from Kabuto, Sasuke ghosted his hand over the blonde's body looking for the new chakra signature that would say it had worked. Sasuke chuckled as he found it rather quickly, already strong and pulsing. His plan had worked, the egg had everything it needed and was well on it's way to forming his and Naruto's child. Moving his hand lower Sasuke sealed the opening in Naruto's canal that had been formed to allow for the miracle to take place. With it now sealed the child would safely grow inside Naruto's body till it was time to be taken out.

Carefully Sasuke pulled himself from Naruto's body, hissing at the friction on his overly sensitive male part. Leaning back Sasuke watched in amazement as Naruto's opening; that had tore a bit from the intrusion, seeped red chakra and sealed back as if it had never happened. Sasuke was immensely satisfied his theory had worked just as he had predicted. He had hoped the Kyuubi's chakra would heal any wounds quickly so no seed would be lost and he had been correct. Not that anymore of his seed was needed, the egg was already dividing well on it's way to forming their child but it was his male pride that had hoped Naruto's body would hold on to his seed, marking Naruto inside and out as his.

Reaching over he grabbed his pants, dressing quickly. From his medical belt he pulled out two scrolls and a bag containing money meant for Naruto and their child's expenses and placed them above Naruto's head. One scroll was addressed to the Hokage giving an explanation and instructions on when and how to deliver their child. He had also instructed that Naruto was to not go on any missions or train, for he needed to leave his chakra for the child. The other scroll was addressed to Naruto, explaining what and why he done these things along with the promise that if he survived he would return to help Naruto raise the child.

Leaning down Sasuke kissed his fingers then placed them on Naruto's stomach where the future Uchiha-Uzumaki heir lay then removed the paper seal he had placed there. Moving to Naruto's face he laid one more kiss onto Naruto's lips.

Grabbing his torn haori he covered Naruto's lower body up to try and preserve the blonde's dignity before gathering up his possessions. Walking to the kunai that remained inside the barrier Sasuke removed it from the ground, dropping the barrier. Forming the seals needed Sasuke transported himself away, leaving those present to deal with Naruto and their child.

. . . Flash ahead several months . . . .

Naruto sat slowly swinging back and forth on the lone swing outside of the ninja academy as he awaited the end of Iruka's day at the school. Tsunade-baba had ordered him to live with Iruka after the incident with Sasuke and he was glad for the company. Time had passed rather quickly and soon he would be a father . . . or mother . . . well a parent anyway.

"It's a good thing I don't have much longer to wait, I'd hate to have buy any more clothes that I'll never fit into again." He was excited but scared at the same time, his feelings about having a brat just depended on the time of day one would ask. Like his feelings towards Sasuke, one moment he really hated the bastard for what he had done. Then he would remember the words Sasuke whispered to him while he was creating this child between them and he found himself praying for Sasuke's safe return.

No word had come as of yet on if Sasuke had killed Itachi or if he was alive himself. Naruto tried to hold on to the hope that Sasuke wouldn't break the promises he had made to him when he left him with this most important duty.

Truth be told a part of him didn't mind what Sasuke had done to him, sure it had hurt some but he had felt worse, he was a ninja after all. 'And most of it had felt really, really good.' He thought, a dark red blush dusting his cheeks.

Not that he could imagine doing those things with anyone else, but if Sasuke came back he could probably be talked into doing them again. Besides in the end Sasuke had given him something precious; someone to love, a family of his own. Naruto had never thought he'd have one being he was the Kyuubi vessel but, here he was expecting a child of his very own. No it wasn't a traditional family but he had never been one for tradition anyway.

This task Sasuke had given him was one hell of a trial that tested not only his strength physically but, also mentally and spiritually. Reaching down to rub the bulge sticking out from under his shirt Naruto had to admit he thought he had passed this trial with flying colors.
