After constantly lecturing his staff about cutting expenses, a married manager discovers that his much younger adult subordinate Yuki has booked them a shared hotel room on their business trip. He once hired her for her pretty face and has secretly fantasized about her sexy body, but he knows crossing the line could ruin his life. Yuki teases him even while he is on the phone with his wife, and his restraint finally snaps. One release leads to another as the devilish junior employee takes control, tangling with him again and again and draining him until morning.
