So if I'm reading your first goal right, you either have victoria being a lesbian (later bisex probably), NTR, or creepy drunk/sleep sex...
I don't know about others, but I don't like to share LI in games, even with others girls, unless I have a say in it, or it happens because I as the MC says so. Having your LI having sex with another girl, is the same kind of NTR that having said LI being with a guy, but most people are ok with lesbian NTR.
I also dislike NTR, so that means two options out.
The other options are kind of rapeish so...won't be there an option that doesn't involve, sharing, cucking or rapeish modes? I don't know a romance option maybe?
