Even now, as a practicing doctor, Ms. Kuroki dedicated herself solely to studying until she obtained her medical license, leading to no romantic relationships with men. She first experienced a man at the age of 25. However, after discovering the pleasure of sex, she became obsessed with dating men like a madman. Although she seems to have calmed down since her marriage, she still keeps a sex friend. Incidentally, she claims to have only had three male partners to her husband, but it's rumored to be over three digits. The reason she decided to appear in this video is because she broke up with a sex friend who had excellent physical compatibility. Since breaking up with that friend, she hasn't been satisfied with any other man, and has appeared to fulfill her overflowing sexual desire.
