My secret that I can't tell anyone...I go to an all-boys school [I'm a very timid kid] and after school, I'm being used as a sex toy by a beautiful female teacher...

A kind and beautiful female teacher is very popular with the male students throughout the school. But that's just the public face. Behind the scenes, she is a super sadistic woman who bullies timid boys in an erotic way with high-pressure footjobs! The gap between the innocent front and the lewd back. A male student who is timid towards an adult woman who skillfully uses the two is trained every day as a masochist slave.
