Yoshioka went out for a drink with his colleague Takikawa on his way home from work. The two who didn't drink enough decided to drink again at Takikawa's house. Despite being late at night, Yoshioka likes Takikawa's busty wife, Eri, who prepares for an evening drink. However, perhaps because of deep sake, I have a quarrel with Takikawa about my work. I managed to calm down the place, but I went to Eri for a night-time gimmick because of my mushy stomach.
