Hypno Mama

The protagonist, Makoto Sakurai, is a high school student.

One day, his new neighbour, Atsushi Uchiyama, tells him an shocking secret about his family: he has a secret sexual relationship with his own mother.

For him, it's completely normal. But ever since, Makoto's way of looking at his mother, and at his friends, has changed.

Then, one day, Makoto's father has to leave for an extended business trip, leaving Makoto alone with his mother. Makoto feels something vaguely unsettling, and his concerns turn out to be a reality.

That day, when he comes back from school, his mother is waiting for him completely naked, ready to start an incestuous relationship with her son. And it looks like his friends are in a similar situation!

Don’t you feel like trying out the “Hypno App” that’s been popping up a lot lately in manga and CG collections…?
This game is a simulation that recreates naughty touch play using a hypno app as realistically as possible!
Instead of just watching a fixed sequence of events, you become the protagonist and train the girl however you like!
Depending on your actions, the heroine will respond with a variety of lines and animations.

After diving into the dark depths of the internet, our protagonist comes across an interesting post about musical theory and hypnosis. The thesis being there exists a certain frequency that can hypnotize a person to do anything that is asked of them. Genius scientists around the world couldn’t figure this one out so leave it to a perverted visual novel protagonist to crack the code to assume direct control of a human brain offscreen. Within the first 10 or so lines of preamble, dive right into dirty degenerate hypnosis antics.

With the frequency perfected it's time to do some science! Rolling up to the meet and greet, NOT using hypnosis to line skip, that’d be too far, you’re finally face to face with *THE* Kanon! Pump the volume of the hypnosis frequency and find out what her boobs look like, how her pussy feels, and become the Producer of their little idol group, all in one day! After that, well, the world is your oyster. Train each idol in the group to your liking! If you’re feeling extra twisted, you can lift the hypnosis on the idol while she is being pumped full of your ‘fan support’ and see her reaction!
