Love Sex Second Base there's a route to dye Sasha's hair blonde and get implants. As well as Bree is a blonde with big tits and a bit ditzy. There's also an option to play as Bree, but as of now not a lot of content for that.
These are all games that affect the Female Protagonist:
A New Dawn story development has kind of slowed down, mostly because White Raven is creating alternate scenes for the bimbo variant of the MC
Defenestration the bimbo content in this game is by far imo the best you can find. And Fresh Mulan seems to be updating it at a steady enough pace. Also the bimbo content is quite late in the current game, but Fresh Mulan has reworked a lot of old scenes to use the art. There's "forced corruption" and mind control. I say "forced" because you have inner dialogues implanted from the hypnosis that you can either side with furthering her corruption or ignoring, eventually getting to a point where one of them takes over and leaves you with less choice.
Caliross mdqp is the creator of the legendary Tales of a Drunken Cowboy. The bimbo content is limited to text change and breast enhancement. But there's also a lot of other corruption based events that will help with the immersion.
Uni There's one route where the MC is coerced into breast implants and then blonde hair, I think it will eventually go further too, but as of right now they don't have all the sprites done for the Bimbo MC. I think it's next on their plate though.
Tales of a Drunken Cowboy Chapter 1 The MC has an AI in her head that coerces her to be more slutty and act like a bimbo. I don't remember what sort of modifications happen to the MC. This is mostly text using RAGS so there are pictures that change with the world.
This is a lot of what I have found and collected.
