It would be nice to have an arc where the clothing store owner follows you back to the apartment, sees the robot, is immediately interested, and joins the player in sex with the bot...
more tongue out options during sex... it's really nice, but too random
doggystyle POV
viewing the android body without sex/being able to lift up skirt etc
Android masturbating with player control on the emotions of the android (embarrassed/shy, mad, smirking/snide, sad/crying)
Bondage options
Late game option to buy a "remote" for the android to control emotion/love/hate, heart eyes, or other features
Option to take the android with you outside (if fully clothed) to increase sanity gain on walks (with potential chance to get caught and have to run which would lose some sanity, additionally the chance to get caught and have to "sell off" the bot for a day and potentially be a witness to what the "buying" is doing with the bot)
some kind of larger array of kinks/interest... facesitting, feet stuff, thigh jobs, armpit stuff, deepthroating, double penetration of some kind, facesitting (guy on robot), rape fantasy, bondage...
I got a bunch more but I suppose I'll leave it at that XD
