String Tyrant 1.0.2 by Saltyjustice

Perverted Education is an erotic game in which the main character, an ordinary student of indeterminate (but legal) age, is slowly pulled from his ordinary life into the twisted depths of a female-led, submissive lifestyle. The corrupting tutelage of three influential women - his Teacher, Guardian and Therapist - will take him on a gradual, yet life-altering journey of physical and psychological transformation.
