In the hallways and corners of a school classroom typical of those attended by schoolgirls, a man exposes his cock and begins masturbating. The schoolgirls, shocked and terrified by the sight, flee in panic—but a few remain, captivated by the man's actions. One girl is chosen and taken aside, forced to witness the man's genitals under the pretense of "sex education." As she trembles in fear and disbelief, he touches her body, performs handjob and blowjob on her, and ultimately proceeds to full intercourse.
