In order to make a business deal with a client a success, Miki is sent on a business trip to entertain the client. Of all people, her boss, whom she dislikes, accompanies her. Although the client sexually harasses her at the business trip, she is forced to drink a lot of weak alcohol so as not to make the atmosphere unpleasant. Drunk, Miki is woken up in a hotel bed by her boss's fingering, whom she dislikes. With no way to escape, Miki 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," Miki says, falling into an unfaithful relationship and actively pushing his dick deeper into her vagina.
