[Synopsis]

A gloomy teacher, whose only redeeming feature is his huge penis, gets his hands on a common sense-altering app and uses it and his dick to thoroughly screw the beautiful girls at school!
"When female students greet me in the morning, they lift their skirts and show me their panties..."
It's an absolutely impossible perverted wish but when he writes it down in a common sense-altering app, it becomes a reality!

Okawa, a bespectacled teacher who has always been a serious teacher, one day comes across a mysterious app.
Reading the app's description, he learns that common sense can be changed simply by "entering the common sense you want to change."
Tired from work, Okawa goes crazy and starts typing his erotic desires into the app.
The next day, all the girls at school start "greeting me while showing me their panties" just as he had entered them in the app!
Convinced that the app is real, Okawa changes common sense one after another to make the desires he has been suppressing come true!!

- When greeting me, female students must lift their skirts to show their panties.
- The student on duty must service my erect genitals.
- During class, they must follow my instructions and accept any action.
- After school, they must receive instruction from me while exposing their vaginas.

He makes the class's most beautiful girl and busty Kumagai, give him a titjob and blowjob and takes the innocent Shiokawa's virginity in front of the whole class.
He also has cowgirl sex with the tanned gal Miyoshi and cums inside her...
With the power of a common sense-altering app, any girl can become a slut and love sex!
