Title: Anger in his eyes Rating: NC-17 Warnings: graphic violence, angst Fandom: Naruto Shippuden Pairing: narusasu (naruto and sasuke) Summary: Set in Shippuden after Sasuke has killed Itachi and Orochimaru. Sasuke is finally reunited with his best friend, but it doesn't go as he expected.
Sasuke had dreamt of this moment for so long. He had decided on the path of revenge long ago, but ever since leaving Konoha he had always felt that empty feeling he knew could only be filled by his cheerful hyperactive friend Naruto. But this was not the reunion he had been expecting. Sasuke had run through this scene over and over in his head. Naruto would run to his teamate and meet him with a warm embrace. Sasuke would finally be able to hold on tightly to what he desired most, and would confess his love for Naruto. But in reality, it was very different to Sasuke's fantasies. Sasuke hands were tied above his head in thick rope, and he was hanging from a cold stone wall. Naruto stood infront of him with angry red eyes, his body glowing with familiar orange chakra. Sasuke knew its source: the Kyuubi. Sasuke was still dazed from whatever had knocked him out, and he struggled to remember how he came to be tied up like this. In his confusion, he stared back into Naruto's eyes with fear, but also great sadness. Naruto finally spoke. "The last of the Uchiha clan. You have shed the blood of your own brother, your path of revenge has met its end. Your goal completed. What do you live for now?"
Naruto sounded different; his voice was deeper, tainted with anger and resentment. Sasuke longed to reply, to tell Naruto he needed him to fill the empty void in his now pointless life, but he could not find his voice. Naruto spoke again. "I finally get to speak to you properly. Now that Naruto has been taken over by his anger."
It was then Sasuke finally undertsood. It wasn't Naruto, his beloved best friend he was talking to, but the demon that possesed him. The Kyuubi smiled, showing pointed fangs. His hand bearing sharp claws reahced out and stroked Sasuke's cheek. "I have been able to take full advantage of Naruto's feelings. I now have enough power for a physical manifestation."
Sasuke flinched away from the clawed hand and whimpered. This was not how he had wanted it to be. He finally found his voice and spoke out against the demon facing him. "Naruto loves me. I know it. He will swallow you whole. You won't be able to take control of my Naruto!" " Your Naruto is locked away in himself. I am in control now." "Naruto... if you can hear me, please fight back! I never stopped loving..." Sasuke's words were interupted by a powerful punch that snapped the ropes away from the wall, but his hands remained binded together. Sasuke gasped at the sudden pain, as his body hit the hard stone floor. The Kyuubi now stood over him, looking down at the pitiful raven. It was then that hours of beatings followed.
Sasuke didn't know how long the agony lasted, but eventually the punches finally stopped. Sasuke panted heavily, his brusied body was making it difficult to breathe. His eyes closed as he tried to make the pain bearable, and he shuddered as he felt a warm moist tongue lick his neck. Naruto (or the Kyuubi, Sasuke couldn't be sure) began to gently suck down Sasuke's neck. Sasuke allowed a moan escape his lips. This couldn't be the Kyuubi, Naruto must of fought back. Naruto continued to travel down Sasuke's neck until he reached the curse mark. Sasuke's onyx eyes shot open when he felt sharp teeth sink deep into his flesh. Sasuke bit his lip trying to silence the painful scream that threatened to escape. Naruto continued to bite fiercely until the flesh marked by Orochimaru was ripped away, leaving a large wound on Sasuke's shoulder.
Sasuke couldn't hide his pain any longer. He moaned out in agony. The blood flowed quickly out of the wound, and Sasuke was sure he was going to die soon. He opened his eyes again and met the red eyes of the Kyuubi. "I've only just started having fun Uchiha..."
