Wife, Toshimi, 27 years old. An intelligent, brainy doctor's family with a deeply masochistic wife—her entire family are physicians. The wife graduated from the prestigious medical Ika○ University, a highly intelligent and sharp-minded woman. It's said that intelligent women have a remarkably high tendency toward BDSM, making her the perfect picture of an elite perverted cunt. Her lustrous skin is absolutely captivating. Today, she'll undergo my "perverted surgery" before going home. Her thesis title was "Human Sexual Behavior and Species Preservation in the 21st Century," a serious academic theme, yet one that's extremely relevant and essential in today's Japan.
