[SDHS-042] I was a secretive person who loved reading, but when I was locked in a strange basement and masturbated in front of strange men, I became aroused by the men's gaze and turned into a lewd perverted woman who went crazy with my masturbation. (Censored)

I, [Kotone], who loves books and is a shy person, finds out about my best friend [Himari]'s secret. I felt a naughty feeling when I saw Himari go crazy masturbating while being watched by a lot of suspicious men. ``Himari...does it feel good to be watched?'' I stepped into Himari's world of masturbation while being watched, and decided to masturbate in front of strange men.
