Karen works for a company that bans office relationships. After her boss sees her eating lunch with a male coworker, he begins targeting her. When they are alone working late, she refuses Yoshimura's offer of a shoulder massage, so he threatens to fire her and asks whether she let the other man touch her. His full-scale sexual harassment starts there. Fascinated by Karen's large nipples, he relentlessly twists, rubs, and sucks them, even playing with them through her blouse while she works, conditioning her body to climax almost instantly from nipple stimulation.
