Behind the prestigious cram school, a dark network preys on high-achieving girls. Even diligent, studious girls with glasses are drawn into forced prostitution. They never imagined their shameful acts would be recorded and sold as adult videos. Reluctantly complying with men's demands, their bodies gradually fall under control. Trying to suppress their pleasure, they eventually let out uncontrollable moans and filthy words under the men's dominance. Afterward, as an extension of their torment, they're forced to masturbate with toys—driven to uncontrollable, inevitable orgasms.
