I found a naughty book by chance in the library, but I couldn't control my excitement and secretly started masturbating! A beautiful woman happened to witness my masturbation appearance over the bookshelf! Beautiful women such as married women, OLs, and librarians who were secretly frustrated were puzzled by Gingin's erection cock that was squeezed in front of them, but they also started masturbating themselves. However, a beautiful woman who can't stand masturbation alone grabs an erect cock over her bookshelf and invites herself to have sex!
