Mirei Imada plays a curvy, capable female manager whose body supposedly distracts every man in the office. After spending the night with her boyfriend, she accidentally arrives at work without panties. A subordinate discovers her secret and takes a photo, then uses it to demand a blowjob. That encounter grows into a string of after-hours office hookups: raw sex instead of overtime, a striptease on the desk, masturbation, and repeated demands for intercourse. Mirei hardly seems unwilling as their secret meetings turn the empty office into a private playground.
