Iinstruction's unclear
nothing i do will give me the Futa Sandy option.
When talking to Asami in Episode 2, choosing "Don't worry. I will help you become a shameless sl-" will open her optional cheating route with Sandy.
Blossom - 3 lessons - requires Bloom / Lesson 3 and Episode 11: Red Yellow Green.
In Blossom, you can either take Asami for your own. Or let Sandy have Asami (which will unlock a bonus option in Chakra 3) (Futa warning)
In Korra's chakra lessons
> Fire: Requires Water
Optional: You can let Skoochy bang Korra
Optional: based on your choice in Asami Blossom lesson, you can let Sandy bang Korra.
