Not to sound like I am complaining(it isn't intended that way), but the MC aspect of most of the stories is starting to get repetitive. You even joke about it in one story. Everything seems to be Zombie-robot control. Maybe I am the odd man out but I enjoy the build up to submission at least as much as the wide-eyed obedience.
Maybe some villains could start using something other than an an instant enslavement. Seems like every time the Gals run into a mind control plot, they are instantly thralls. Why not have them run into someone who takes a little more time bringing them under control? Maybe a stage hypnotist catches one of them when a group has a night out and proceeds to build off of that. One Heroine gets dragged deeper and provides some advanced tech that then gets used on some others.
Or maybe a 'siren' who can only gradually change the direction of their thoughts. Step by step making one of them want to be her slave. Or just controlling the men around them to manipulate them into some other MC plot? Siren(as next door neighbor?) seduces/enslaves boyfriend then boyfriend slips Heroine a micky and proceeds to use regular hypnosis, plants trigger and deepens over and over( Several scenes shown over time moving to more and more control). Eventually, heroine ends up thinking Siren is best friend (with benefits?) and will do anything she asks.
The Love and Obey storyline was good this way but still turned all the women into little more than wind-up dolls. Some story where the villain slowly manipulates the emotions of the heroines might be fun. Pheromones, magic or some form of telepathy make him/her almost irresistible. Several of the girls get interested and fight a bit over him/her. One is picked and gradually enslaved. Then they pick off some others one by one with various methods(Example, Snowflake and Solaria squabble over him, He enslaves Snow and then she invites Sol for dinner with them to make up and he ensnares here too)
I really liked the idea of the GreenTooth device. Just wish it wasn't quite so overpowering. I would have preferred if it opened the mind and let the caller leave something like a post-hypnotic suggestion.
Any mind control where the eyes don't turn green would be a welcome change.
Not that I don't love what you've done. I could just love it more!
