UPDATE So I revamped the story. I know where it's going and what I'm planning on doing and I can't squeeze everything in that little paragraph XD Here's a brief prologue:

Uchiha Itachi has become addicted to drugs. He leaves his family without an utterance to pursue his life in the dark side. Meanwhile Sasuke tries to live his lie without the most important person to him. He mops around for weeks ignoring his friends, including his best friend Naruto who is gradually building up a crush on him, until his cousin Sai comes in for his annual summer visit. Sai seduces Sasuke and eventually the two form a sexual and emotional relationship reminiscent of the one Sasuke had with Itachi. They continue on until Sasuke feels guilty for almost forgetting his long lost lover and Sai reveals to him the whereabouts of Itachi. The brothers met and reform their relationship forcing Sasuke to forget about his cousin until he leaves. Naruto, able to hold back his emotions reveals to Sasuke that he is in love with him and forces himself upon his best friend, while Itachi continues to use drugs behind his brothers' back. Sasuke becomes a mangled mess of emotions as he's unsure who to trust and what relationship he should strive for leading him down a dark path, and a horrific event that changes the lives of the Uchiha family forever.

All Warnings still apply.

Lots of graphic sex scenes as well as mild ones, incest, rape and drug usage.

Mature audiences only

Enjoy :)
