A teacher named 'Yui' at a prestigious school would relieve her work stress by masturbating unnoticed in the back of the classroom during lessons. However, the thrill of exposure drove her to seek more intense stimulation, making her acts increasingly extreme. Just then, she was caught by a school janitor while masturbating naked in front of a vending machine. Blackmailed with this evidence, she was raped in the staff room and trained as an exhibitionist slave. She performed public indecent acts on buses, received multiple ejaculations in arcade gang● sex, and even masturbated publicly in front of her students. The entire process of this female teacher falling to the depths of lust!
