Korra dreams of a future where everybody gets along and she can get monster sized monster cock whenever she wants, but even in her dreams she goes into the Avatar State when she cums and can't remember it.
So like a good student she practices day and night... even on people in prison! till she can cum and remember how it feels.
Finally she masters her own orgasm, falls asleep, and when she wakes the prisoner is gone... oh well, I can catch him later.
