Angel of Darkness (淫獣教師　実写版) 29 years old

At a high school in Tokyo, several of the female students have been moon-lighting as prostitutes. A teacher catches onto this fact and goes about putting an end to it. Things go awry when he discovers he turns into a sex demon with tentacles whenever he gets aroused (huh?). He turns from savior to vilifier, poor prostitute school girls.
