Karlsson's Gambit you start out serving a long sentence in prison when you're offered the chance to get out early if you accept to join a powerful company's "training program" that is later revealed to turn its participants into femdom slaves, if they even survive. Huge amount of branching & consequences with both dom and sub paths, you can eventually climb out of slave status or fall from grace depending on what you say and do.
Estate Dominate you and your sister agree to work at a rich and powerful woman's isolated manor for the summer to pay off a debt. The job description didn't mention indentured servitude/sex slavery. Abandoned very early in development.
