Minor bug here, there's unreachable dialog at the dinner scene because of a mixup on chloe and emily's variables, you have to have them both fail max to get the bare bottom dialog for Emily because the test is for chloe missing all three.
I don't think it's possible to get each one to miss all three events without cheating because there's one hour they're both studying at the same time.
Code:
label e030_c2_failed_001:
if e030_c2_fail > 1 and cDay > 10 and "breakfast_spanking_hint" in nList:
$ nList.pop("breakfast_spanking_hint", None)
if e030_c2_fail == 2 and cDay > 10:
...
elif e030_**c1**_fail >= 3 and cDay > 10:
Actually it may be reachable dialog by getting chloe to miss all three events the emily dialog will trigger as well. It's a trivial fix. It doesn't change their evening spanking scenes either way, Emily will get bare-bottom paddled even if Rachel says nothing at dinner.
I did notice that it seems like Chloe always distracts you when you try to work together inside. I've never gotten the study help event with her, but I do get it with Emily.
This game scratches an itch I've been missing since Big Brother was abandoned.
