Wouldn't have to be the literal Fire Emblem girls, but it could be, some good designs/personalities there to use at least.

>enjoyment that women born into slavery cant give.
Could do a bit of both, maybe the set-up is that you're from a city-state or small kingdom that is the kind of lewd patriarchy you see in these threads, maybe have some ability to customize your society, but that could be a lot of work.
That way you have some starting slaves that are loyal by birth, and then you go out and grab whatever powerful women you can find, bending them to your will either through careful training, or just fear.

If you want a more grounded setting you definitely can. Either do a "pre-apocalyptic" like in Free Cities, with only a bit of society building and an emphasis on the direct slave training(that way its not just LITERALLY Free Cities) or just modern. There are many slave trainer games to look at for potential inspiration, I was mostly thinking fantasy cuz of what the first anon said and the thread theme
