[Natsu Tojo x bondage exposure] A girl who was interested in an SM book she picked up by chance and was excited about being tied up and being seen was hiding outdoors and indulging in shameful masturbation. One day, she was spotted by her janitor, an uncle, while she was doing exposure play on the school grounds... The girl who knew the pleasure of her exposure SEX, went to her more extreme exposure play. I'm immersed in it... A perverted masochist awakening training work that exposes perverted shame everywhere in the school, the library, the cafe.
