One day, while Haruka was working late, her despised boss suddenly made advances toward her. When she tried to push him away, he fell and became enraged, then raped her—and recorded the entire incident on camera. From the next day onward, he used the rape video as blackmail, forcing Haruka into humiliating sexual acts. Initially resisting desperately, Haruka gradually transformed as her boss repeatedly violated her with his huge cock, eventually craving her own body's pleasure and climaxing uncontrollably.
