There are those games, but it's rare in the genre. You see more Big Brother-type games and romance over my preference for forced, coerced, or accidental incest scenarios in games. 

I really hope to find a game where they're slowly paid to take more and more corrupt actions until it leads them to sex or worse and they hate it the entire time, never something they end up loving, really haven't found one that I'm happy with.
