I will refer to the "took the photo of the couple" path as the "dangerous game" path, because this is how it is referred in the game files.
I did a playthrough with URM and found out the following:
1) Wife's love points and wife's slut points don't affect anything - they are never checked
2) Cuckold points are only important on the "dangerous game" path:
cuckold points ≤ 4 - the route will be closed (it's checked short time after she took the photo)
cuckold points ≤ 14 - wife engages only in light teasing, mostly verbal, she doesn't have sex with other men
cuckold points ≥ 18 - wife is a dirty slut - she sucks dick of the guy who intimidates her, she touches the dicks of the brothers on the beach, gets cummed on her back by a random dude from the beach, then she initiates a threesome with the brothers because she is too horny
cuckold points ≥ 20 - she suggests the husband to get pegged by her
cuckold points ≥ 22 - she takes bulls' cum in her mouth and teases the husband with doing the same (tasting their cum)
3) on the Vanilla and Gambi paths cuckold points don't change much, maybe open a scene with the German wife and some additional dialogue, but that's it, they are mostly not checked
Daughter's love points only determine whether she sends her photos and videos, something she sends only with love points ≥ 4, something with love points ≥ 6, any additional points don't give anything (IIRC)
If you refuse to help the ballerina, she will reveal that the daughter is a slut who fucks older guys, loves anal and generally fucks a lot - this happens on all paths and regardless of any other choices, even on Vanilla
If you refuse to help the ballerina or if you pressure her to cooperate - she will reveal in the end of the day 2 that the wife cheated on you in the past - this happens on all paths and regardless of any other choices, even on Vanilla
render9000, I have three small suggestions:
1) On the "dangerous game" path, I think it would be nice to have "a middle ground" between "cuckold points=14" and "cuckold points=18" - e.g. with "cuckold points=16" it would be nice if she jerked off the brothers and got cummed on her back by the dude from the beach, but didn't suck Decart's dick and didn't initiate threesome with the brothers. Basically something between verbal teasing and total unhinged slut
2) Untie bisexual stuff from the cuckold points, some people like it, some - don't (I don't like it at all), so I'd prefer if we could just tell her that we are not into cum eating and stuff like that, so that she didn't "tease" us with that - I'd prefer if bisexual content was just a separate flag
3) Pegging by women is hot (for me) and better be a separate flag as well - when Petra teases the MC about pegging it is hot, but learning about the guy who got fucked by an old african dude is not hot, it belongs to the 'bisexual' territory
