I mean I guess it depends on how close you are to these women. If you don't really know them personally or just know them professionally, you're basically just playing as a pimp, which is fine. But if the girls are supposed to be family of yours and close friends? I don't know man... Context of the game really matters.
You are just playing as a pimp in these games, whoring out people you know just adds spice. Personally I don't really get the whole incest thing, I don't mind but it doesn't add much, but I love prostitution stuff. It's a power fantasy, because you're the one making the money. The writing is often very bad due to men being such pussies these days, and men usually write this stuff. So you end up with a dude that's all "poor me, what will I do, maybe I should ask my (step) mom and (step) sister for help, I don't really want them to be whores but i have no choice", (don't know if this game is like that since I've not played it yet) then you have to convince them and they reluctantly agree blah blah because the writer is trying to justify that he gets off on women being treated like worthless whores. And then he'll probably try to balance it out by adding a dominatrix in there to be the truly evil one while his Mary Sue MC is all like caring and responsible. But if you try actual good power fantasy games like Jack or Free Cities then you'll see what it's really about, it's about being the heartless cruel monster we can't or won't be in real life, the guy that doesn't care about silly emotions or morality, a truly free man. That's the appeal, at least for me, and if the male MC goes all wimpy and emotional about it it's always a huge turn off for me, because I want to play a monster and not some lover boy. It's just cucking if he rents them out then goes to bed crying about it, because cuckholding is about inflicting emotional pain by cheating on a codependent loser because the cheater is a narcissistic sadist. But when you're whoring out your girls then you're the narcissistic sadist that are making them fuck hundreds of guys so you can get rich. Basically the difference is if they're doing it against your will, or they're doing it because it's your will.
