Blowjob from Zhu Li: go to the city streets of the statue of Aang and talk to her and say she can pay using your mouth
Jinora's blowjob: go to the statue, talk to her and "fail her again"
Fucking Lin Beifong in the cell: one day an equalist will be alone in his room and give a message from Amon, go to Shady and deliver the package on the city streets (needed for Korra), enter the statue of Aang and buy what you need , hand the Equalist over to the police and the rest is intuitive
Fuck Zhu Li: One day Pema will say she has a call for you at the study, is Zhu Li, go to the police headquarters and talk to Lin, go back to the study e go to the city streets and talk to Zhu Li, wait one day and call her.
Fucking Korra with Asami or Pema: after learning to block chi, buy Shady's clothes, talk to Korra at the statue, fuck her ass or not, call Asami at the office and enjoy
