This game is great. The dev needs to redo the entire grind for sure, but just use console commands to give yourself money or to adjust character relationship values if you need to, and it is super hot and sexy as fuck. There is a slow burn of sexy moments in which sexual tension increases for both the characters and the player.
The incest fantasy is entirely based on the fact that characters have familiarity and rising sexual tension, rather than strangers fucking which is hard to do correctly in a way that makes the player get invested in the sexiness. Because of that, the sexual tension and moments that build up between characters in this is amazing - this game could be one of the best on the site if it fixed the grind and as it stands it still is if you console commands to negate the unpleasant parts of the grind.
From the older sister's unbashfulness about you seeing her naked, to the younger sister's increasingly obvious sexual infatuation with you, to your mother's strong commitment to regular morals, this game has some of the best sexual tension in the industry. The models are sexy and believable.
I would give this one a try, use console commands once you don't wanna grind, and don't let these other reviews get you down.
To another well-liked review below - you can study interests only 3 times per session, not 3 times per day. You can just sit in a single night and max them out, it's really not an issue. You have a lot of extra time in this game, just get them to max early in your downtime and then everything is easier from there.
To potential players: make saves when you find out what 5 conversation topics a character likes, so that you can just open your save menu and double check later one what they like once more.
