BBAN-180 - Female warden corrupts prisoners into lesbians

The premise of a guard turning a prisoner into a lesbian is boring. It would be much more stimulating to reverse the master-servant dynamic, having a masochistic guard being toyed with by the prisoner to create a sense of perversion. In this case, a mature woman in her late 30s or 40s would be better as the guard. Alternatively, making the new prisoner a notorious villain (lesbian) who forces the guard and a senior prisoner into submission would also be interesting. Even if they didn't change the premise, they should have shown an intense lesbian scene between the guard and the senior prisoner at the beginning. Casting Mao Ito as the senior prisoner would have been a better fit.
