In the seventh installment of the "Study §" series, Yae Yaesawa finds herself alone in the library, her eyes wandering from her books to the window, where she imagines her classmates in various lewd acts. Her imagination runs wild, and she begins to touch herself, her fingers tracing the outline of her pussy through her tight uniform. She can't help but moan softly, her body aching for release. She masturbates furiously, her imagination running wild with scenarios of being fucked by her classmates, until she finally cums, her body convulsing with pleasure.
