The women witnessed other people having sex on the security camera while at work. They were shy and turned away from the bold sex that continued without knowing they were being watched, but they couldn't help but look at the screen and became aroused, reaching for their crotches and starting to masturbate. When they were no longer satisfied with that, the part-time girl gave in to her arousal and had sex with the store manager, and the female security guard gave in to her arousal and had sex with a salaryman in the office.
