it is a flash back to the begining of the original story but the itachi part
"What the hell are you talking about?" Kisame said very curiously.
"Remember, last night."
Kisame thought back,"Oh Itachi I love you, come with me and lets have some fun."
"Oh Itachi you are so hot, please, I need more, I need you."
"Of course Kisame anything for you."
"Wow, now that I remember it I don't think anyone needs to know about this." Kisame said as serious as serious can get."
"Fine, if you don't want anyone to know then ok with me."
"Thanks, so same thing tonight?"
"Sure! I'm game and he will be ready."
As they are walking along Itachi would not stop talking about the night before and fun it was and finaly Kisame looked at him and told him to shut the hell up.
Then night came and they wre having the time of their lives and so were Tsunade and Sakura.
