Sayumi is 26 years old, married for two years with one child. She is the daughter of the president of a popular construction company known for remodeling properties featured on TV shows like "Before and After." Raised in a wealthy household, she's lived a life without any hardships—a beautiful housewife with the graceful aura of a traditional Japanese woman. In reality, however, she's an insatiable, shameless pervert. An avid solo traveler, she has conquered the cocks of men across the globe. Her wildly depraved nature was sparked by witnessing a close friend, a prostitute, having intense sex in Amsterdam's red-light district. In countries where drug use is legal, she's let loose and indulged in wild, uninhibited fun. Constantly driven by an urge to fuck anyone, anytime, she exudes an intensely erotic allure.
