Corrupted Saviors: Literally your description, but as a text-only superheroine corruption simulator. Gameplay takes some getting used to, but is quite rewarding once you know what you're doing and the heroines feel like rats in your maze.
Star Knightess Aura: far from completion, but promises to be the most thorough corruption arc you'll find. What's there is really good, but even at 10+ hours long it's no more than 15% of the way through. Probably closer to 10%. But if you like mind-control and heroine corruption, definitely check it out.
Accidental Mind: As long as you don't mind text-only and mind-control/hypno, it's one to keep an eye on.
