Finally got around to reading through the sequel. Major kudos to the writer for enhancing the original nurses' character and interactions + making you feel for them, making the main character more bearable (even if it is partially via him shutting the fuck up and being a pet for 2/3rd of this), and giving the new nurses really solid personalities on top of making them understandably resentable. Gotta love a nukige you can actually get at least somewhat engaged in, especially a femdom one.
In terms of weaknesses besides the translation having a shitload of typos, while the first two nurses are pretty solid, they really lack the mental weak spot that everyone else had; maybe that's supposed to be the difference between the first game's nurses and the OG Three, but then the last one does have a pretty big one. Also, this has got a pretty big case of status quo, where even after the MC is drugged and fucked completely mindless, by the next day/nurse he's just fine. That kind of shit would mentally scar you for life, it's not exactly something you shake off the day after. I wouldn't be surprised if at the start of the next one he just goes "man, can't believe I got drained and choked to the point of literal death yesterday, what a wacky adventure".
