SDHS-042 I, a book-loving shut-in girl, was locked in a suspicious basement and masturbated in front of strangers. Excited by their gazes, I squirted my juices everywhere and became a perverted slut.

I, [Kotone], who loves books and is a shy person, finds out about my best friend [Himari]’s secret. She sees Himari masturbating and going crazy while being watched by a lot of suspicious men, and she feels horny. “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.
