Tired from playing the role of "Iron Mask," I discovered the pleasure of standing on the podium during the day and wandering around the school naked at night... I stuck out my lewd big ass and exposed my asshole, and was humiliated by the students... A total of 9 scenes of me writhing in shame and pleasure in the library, rooftop, and gymnasium storeroom! 01. The students call me "Iron Mask"... 02. I get addicted to masturbating in the hallway after school 03. Masturbating on the rooftop and taking selfies 04. I put up selfies in the classroom... 05. My students find out and I have sex in the gym storeroom 06. I film myself masturbating in the school at the students' shameful command 07. I show off to the users in the library and provoke them 08. I confess my shameful exhibitionism in the classroom 09. The "Iron Mask" finally collapses completely in the class photo session in the health room, and I happily become a sex slave in front of my students...
