Off the top of my head:
Motoko Kusanagi (Ghost in The Shell).
Raven (Teen Titans).
Morrigan, Merrill (Dragon Age).
Samara, Jack (Mass Effect).
Samus Aran (Metroid).
Tharja (Fire Emblem).
Cornelia li Britannia (Code Geass).
Korra (The Legend of Korra).
Lana (Archer).
Black Widow (MCU).
Ada Wong (Resident Evil).
Some examples I would have included but have omitted from the list include Sera and Cassandra Pentaghast from Dragon Age (the former because she is predominantly a lesbian and I wouldn't want to make her change what sexual preferences she has while the latter is canonically immune to mind control) and Bayonetta, because she is not a lady deserving of being a sub's position. That being said, Bayo would be more than welcome to come in and enjoy the ladies as she see fits.

And they'd all have a variety of triggers for sexy/fun situations, like:
Zombie walking
Pet Play
Mindless slave chanting
Unaware
Lovestruck
Extra-sensitive
Too bad this is and always will be a fantasy...
Don't forget about dancing and hands free orgasms! But yes to a lot of these suggestions.
