An office lady who committed misconduct at work is caught and blackmailed, forced to serve the building's security guard. Her natural big tits and helpless situation make it impossible to suppress her arousal as she drips with pre-cum, ultimately begging him for his giant cock. This intense blackmail and blowjob drama unfolds in the Tempting Office Lady series from Big Mocal's Daikichi label, starring Fujiko Sakura and Madoka Touno.
