To celebrate the successful completion of an important business meeting, Ohno decides to have a drink at his colleague Natsuki's house. He was envious of Natsuki and his big-breasted wife, Reira (Natsuki Reira), who were on good terms with each other. At that time, when the drinking party is nearing its climax, Ohno gets into an argument with Natsuki over a trivial matter. However, Natsuki passes out on the way, and Ohno, who is left alone, approaches Reira in order to vent his frustration.
