Has promise. Here are some suggestions
Make it so hypnotising the girls actually DOES something(Other than the sex scenes). Maybe you can change their clothes after hypnotising them to a certain level, or, in the cases of Joy and Mallow, pay you more after a certain point.
Maybe make it so that there is an option to just hypnotise someone, and skip the scene. It's annoying having to go through all the scenes every time, and if you want to hypnotise someone, but dont want the scene (Like Cheren) it's even more annoying
