jugo knew that ever since kimmaro raped him and gave him STD.......his transformations were not that insane anymore.......he yearn for some1 like kimmaro to rape him again but that person couldnt be found until Sasuke came along and raped him as well, making his transformations at ease again........Sasuke enjoyed it so much that he broke up with Orochimaru and killed him......but now that sasuke realizes how much suigetsu wants to rape jugo, he resurrected orochimaru so he can start over again with him......he misses the times when orochimaru undresses him and rapes him while he moans......
