On a business trip, she unexpectedly shares a room with a useless subordinate who is incompetent and has a terrible personality for one night. "I don't even want to talk to him during work, so being with such an irritating man outside of work is the worst." Her female boss, who thinks so, gives her sleeping pills and takes a video of her naked. Her weakness is exposed, and she is now the one giving orders, but the other one is following... "Mei-san, let's have lots of sex together tonight." A humiliating night in which she is made to cum over and over again by her incompetent subordinate at the office, until the morning comes.
