Alright I dig everything so far. I hope Shizu gets her comeuppance though. I don't think she's extorting or blackmailing Adelaide in any way, I think Adelaide's just shy about their promiscuous shenanigans, and the fact Shizu basically outed that Adelaide uses her apparently expensive ass baton as a dildo, definitely something she's definitely embarrassed of. Its apparent in Adelaide's scenes, she definitely doesn't take the lead like the other 3 do.
Also there is no NTR or blackmailing. There is however femdom and blueballing. But I'm sure we can get to Shizu's dino chicken nugget loving heart soon enough.
