The best of this kind is certainly After Invasion. In a dystopian world the protagonist, who can be male or female (I only played the female version) comes home as a sort of war hero, with quite some wealth and power at her disposal. In that position she gets to dominate her mother, sister and neighbors. Basically anything goes in this game, though I opted to play a lesbian only route. My clear favorite of all porn games.
Inevitable Relations: The female protagonist lives with her wife and two children and discovers that she finds her daughter quite attractive. While not dominant in the sense the she puts the other characters and chains and whips them, she is still a strong independent woman who is in charge and decides the further course of the story. Beautiful artwork.
Mind Over Matter: Mind control game, where you can play as either female or male protagonist.
Ladies Superleague of Lesbos: Lesbian sex fights with an MMORPG-like inventory and skill system. Still in a very early state of developement, but an idea to good not to love.
Milf's Tale: I don't know yet, wether the protagonist will one day be able to be dominant, but she can already make a lot of decisions and one of the hottest lesbian milfs ever to rear her pretty ass on any screen.
If you have enough time, try them all, if you don't: Try After Invasion!
