Mitsuki is going on a business trip to entertain a client in order to make a business deal a success. Of all people, her boss, whom she dislikes, is accompanying her. Although she is sexually harassed by the client during the business trip, she is forced to drink a lot of weak alcohol so as not to make the atmosphere unpleasant. Drunk, Mitsuki is woken up in a hotel bed by her boss's fingering, whom she dislikes. With no way to escape, Mitsuki gradually becomes at his mercy as he gives her pleasure in the shared room. His fingering hits her G-spot with precision, and they have sex all night long. "I hate it, but... I'm coming again," Mitsuki says, falling into an unfaithful relationship and actively guides his penis deeper into her vagina.
