Seiko is an elegant-looking beautician by profession. But her true nature is that of a masochistic, anal-loving pervert. True to her words, "I don't have much in the chest area, so my pride is in my ass," she boasts an incredibly erotic rear. When faced with restraints, she can barely contain her excitement, openly revealing her deeply submissive side—seeming to crave nothing more than being dominated. This time, we not only subjected her to intense "torture," but also pushed her into aggressive, forward "attacks." Instinctively seeking a satisfying embrace, men are met with her teasing reply: "I feel really good in your arms, you know?"—a line that instantly stirs the heart.
