One day, Miho received a call from her husband's younger brother, Jiro. "I've moved to the neighborhood, and I want to meet you." Miho had been dating Jiro before she got married. Although she hesitated, she went to Jiro's house to help him move, and once again found herself in Jiro's hot arms in the small one-room apartment. Her lust never cooled, and from then on, Miho began spending passionate time at Jiro's house almost every day after her husband went to work.
