A full-time housewife in her 16th year of marriage. She has a 12-year-old daughter. Her husband is 5 years older and the president of a venture company. Sumire Ikoma is 40 years old. Although Sumire has lived a comfortable and leisurely life without any inconvenience so far... "When I was young, I didn't doubt anything and thought I was so lucky... But since I reached middle age, there has always been a sense of "hunger" in my heart that won't go away... I want excitement. I want to feel the thrill." The hunger that cannot be wiped away with twice-weekly sex with her husband, she wants to be satiated until she is full.
