Ena Koume, a secretly busty office worker from the same company, invites a coworker on a drive to discuss work, then suggests visiting a love hotel out of curiosity. Once alone, the usually reserved Ena bares her huge tits and seduces him with a titjob. When she realizes he will do whatever she says, her dominant side takes over, and they spend every available moment having a titjob affair until he repeatedly cums between her breasts.
