SDHS-042 — I'm A Book-Loving Loner, But When I Got Locked In A Suspicious Basement And Started Masturbating In Front Of Some Strange Men, I Got Excited By Their Gazes And Turned Into A Lewd, Perverted Woman Who Squirted Juices And Went Crazy.

I'm a book-loving gloomy girl named Kotone, and I've found out my best friend Himari's secret. I saw Himari masturbating while being watched by a bunch of suspicious men, and I got horny. "Himari... does it feel good to be watched?" I stepped into Himari's world of being watched and masturbating, and I ended up masturbating in front of strange men.
