Inexperienced office worker Aoki is constantly bossed around by his superior, Amiri Saito. One day, he commits a major blunder at work so severe that getting fired wouldn't be surprising. But instead of reprimanding him, Amiri—dissatisfied with her inadequate husband—demands sex as punishment. Craving pleasure she can't get from her spouse, Amiri indulges in NTR infidelity, enjoying the thrill and stimulation of having sex with other men right in front of Aoki as a form of twisted training. As her desires spiral out of control, Aoki is forced to reevaluate his position and role in this dangerous game.
