AN: INCEST!

Itachi loves his little brother.

He watched Sasuke grow from a cute little child into the gorgeous teenager he is today. Itachi always knew that his feelings for his little brother weren't right. But there was nothing he could do about it.

Itachi and hormones are a terrible combination. But Sasuke's innocence made up for it. He couldn't take what he wanted from his little brother. So he tried different things. Sasuke was very naive when it started. So there wasn't really a problem.

But Itachi was afraid of tainting his little brother. That's why he never touched him like he wanted to.

But now that Sasuke has a boyfriend his innocence would be taken away. That blond kid was bound to taint Sasuke. And Itachi couldn't do anything to change it.

He gave Sasuke the necklace his mother gave him when he was nine. It was a very special necklace. His mother told him to give it to the person he loved the most. Even at that age, Itachi knew that only Sasuke could have the necklace. So he waited. Waited to see if he was loved in return. And he was. But not the way he wanted to.

So Itachi gave up. He gave him the necklace. Saying only that it was his mother's. He didn't mention the part about giving it to the love of his life. What Sasuke didn't know wouldn't hurt him.

And he left the house. Kisame's place wasn't that far and the weird man always had alcohol and conversations stupid enough to keep him distracted. He didn't want to stay in the house and hear how his brother was being taken.

Kisame's house was a wreck. Last month was Itachi's 23rd birthday and Kisame decided to throw him a little party there so there was enough alcohol to drown his concience.

So he drank until he forgot about everything. Well... everything but Sasuke. But he felt different now. Somehow things changed. Itachi didn't have to give up on Sasuke. Everything was so clear now...

He got up the couch and left Kisame's without a word. He couldn't walk without stumbling but he remembered the way home. So everything was alright.

When he got home he tried to be very quiet. He didn't know knew why but he didn't make a noise anyway.

He got to his room on the second floor. Sasuke's room was just across the hall. He walk into his room and closed the door slowly. He could hear something. But just barely. Someone was talking but no moaning could be heard. That made Itachi feel very happy. The blond kid won't taint his brother. He doesn't deserve to have Sasuke.

All Itachi needed to do now was wait. Wait for the blond to go home or... make him go. He shouldn't be there anyway. The stupid blond just wanted to take Sasuke's innocence, Itachi knew it and he wouldn't let it happen. Not again.

When Orochimaru took his body and tainted him, he just let it happen. It wasn't so bad... sometimes Itachi even asked his teacher to take him. But it always felt wrong afterwards. He felt dirty. Like he had been stripped of his own skin and everyone could see how filthy and weak he really was.

He banged his head against the door hard. Sasuke would make things better. He was pure. He would clean Itachi. And his big brother would have something that belonged to Sasuke. And nobody would take that away from him.

The sound of footsteps and the front door being closed was proof enough that this was meant to happen. He hurried to his little brother's room and opened the door.

"Naruto? That was fast..." His little brother looked surprised. Naruto... Itachi was glad to know the blond's name now. If he remembered correctly he had been dating his little brother for... what? 1 year, 10 months now?

"'Tachi! I know it's going to sound stupid. But this is not what it looks like. Well... I mean.... I didn't... we didn't-"

"Naruto, huh? The blond that just left? Interesting... I'm not really surprised. I knew you got yourself a boyfriend. I'm happy for you, little brother. I just wish he could have stayed a little longer. You haven't introduced us after all." He won't taint you, little brother. I won't let him.

"I'm sorry 'Tachi... I know I should have told you sooner..." But he already tried, huh?

"Mmmh... we haven't..." Itachi's body was moving closer to Sasuke now. And the blush on his little brother's face seemed to glow on his pale skin.

"That's good" So beautiful... so pure...

"I... guess so"

"You know, Sasuke? My first time was not what I expected. It was with the wrong person at the wrong time. The first time should always be special. Mine was actually horrible. But we can change that, you know?" The smile on his lips seemed to make Sasuke nervous. And that fact made him smile a little wider. He sat on the bed, close to Sasuke and never breaking eye contact.

"What do you mean 'Tachi? How can you change that?" So innocent... He rested his hand on his little brother's shoulder and leaned forward.

"Well, little brother, that's quite easy. Your first time is going to be special. And what happened on my fist experience will be erased after this." His nose was almost touching Sasuke's and his little brother's eyes widened making him look even younger. "Because I am going to be your first. And I'll make sure to make it imposible to forget"

Sasuke was terrified. He didn't want to do this. They weren't supposed to do this. They were brothers and he loved Naruto. He wanted to wait until he was ready to give himself to Naruto. And the person licking his cheek right now wasn't his brother. His big brother was always calm and collected. This man in fron of him was a stranger. So yes, Sasuke was very scared.

"S-stop playing 'Tachi... You are joking right?... 'Tachi..?" His brother's lips were attached to his neck now. Sucking hard on the tender skin. When he bit Sasuke where neck meets shoulder he yelped and tried to push his big brother away.

"D-don't... N-no!! S-stop it!" 'Don't stop!' I won't little brother...

He grabbed both of his little brother's wrist in one tight fist and pushed them against his soft bare chest. With his other hand the unbuttoned his pants and pulled the zipper down, freeing his hardening member. He could hear Sasuke screaming and thrashing beneath him. But he couldn't make the words out.

He settled between Sasuke's legs, spreading them wide. He put his tip against the boy's entrance, prodding teasingly. He remembered the words Orochimaru told him on his first time. The way his teacher took him and the feeling of being filled. He never had sex with anyone else. But he knew what to do because Orochimaru taught him. Many times.

"Don't do this... please 'Tachi... please!!!" '...Please!!!' He screamed as his older brother pushed his shaft into his tight ass slowly. Sasuke screamed again as Itachi pulled out and slammed back in, slightly tearing Sasuke's tight passage.

"Please, 'Tachi!!!" Sasuke screamed as Itachi hit his prostate over and over again relentlessly. He was painfully hard now. He didn't know for what was he begging anymore. His body was betraying his mind and he was aching for release. He was now crying and screaming his big brother's name, out of both pain and pleasure. Little did he know that there was someone watching them from the doorway.

"Sasuke!" Itachi yelled, slamming roughly into his little brother. Itachi was now pumping his little brother's length. Sasuke let out a choking sob. "Please!" he cried, arching off the bed, his legs wrapped around Itachi's hips.

It was becoming too much. Sasuke realized his hands had been released and both of his brother's hands were grabbing his hips painfully. Itachi was digging his nails into Sasuke's slender hips.

"ITACHI!!!" Sasuke screamed at the top of his lungs, tear's rolling down his face, his seed covering both his and Itachi's stomachs. Itachi came a moment later, grunting Sasuke's name, pulling all the way out and slamming back in to the hilt, releasing his seed into the hot tight passage of his little brother. Their screams mingled together as they both found release. Itachi pulled out, then took the shaking and crying boy into his arms, laying down beside him.

"Shh... It's okay, little brother..." Itachi spoke softly, trying to catch his breath. One arm wrapped around Sasuke's waist and his other hand caressing his little brother's wet cheek.

"W-why I-Ita-" Sasuke sobbed but was interrupted by a cold voice.

"Here's your gift. Happy birthday Sasuke." And the blond left.

Sasuke stayed there. His eyes wide open with tears still rolling down his cheeks. He turned his head slightly to look at his big brother's face. Itachi's eyes had widened too and his lips were parted. However, he didn't looked at his little brother. He just stood up and left Sasuke's room to go to his own, locking the door once he got inside.

When Neji got there he found Sasuke curled into a tight ball sobbing and shaking holding a big teddy bear with a bright red bow around the bear's neck.
