This I don't get. If it isn't in your route, it didn't happen in your universe. She's not getting banged five times a day. That only happens if you pick the other route. Likewise, if you're dominating Fiona on your route, she's not dominating you because that's what she does on the other. What you're complaining about is like complaining that there's an option to have the protagonist be male or female in a game, because you only like male protagonists. Well, pick male. Done.I must say that for me its is disappointing that option. It's hard to be on my route where Evelyn will be a beautiful model and have romantic dates with the MC while on the other she is gangbanged 5 times a day.
Don't get me wrong. That doesn't mean you are wrong to say that having her turn porn star doesn't make much sense, character-wise. And that's something I'd agree with. If you told me that the mom was going to have relationships with others, I'd expect it to be with her best friend, the police officer, and/or maybe the brat from college would do something to her. Porn wouldn't even be on the radar. Not without some major groundwork laid. As in, maybe as something that happens a ways down the road on the modeling path. But, admittedly, it has been a few updates since I've played this game, so can't really comment fairly in this regard.
