I truly understand the sentiment. I never intended for the dynamic to reach any stage of approval from Milly’s side. It should usually result in a takeover at some point.
I have plans to include plenty of 'Milly and Nadya content' in the Netori path, so featuring it in the Futa on Futa path felt a bit redundant.
The corruption will continue to focus primarily on Milly, and the true climax moments like the one you just anticipated are being saved for the wrap-up of the Futa on Futa path.
