I actually watched the AV starring Natsume Saeharu in a secretary-themed role, and the quality exceeded my expectations. First, the video quality is impeccable, with stunning visuals, but the audio is somewhat muffled, making some dialogues hard to hear, which is a slight drawback. Particularly in scenes where Natsume Saeharu handles her忍耐汁液 (endurance fluids), the dialogue is crucial, so clearer sound would have been ideal. However, her performance is outstanding; her fellatio, using her slender physique, exudes a 'devouring' erotic beauty that makes anyone want to kneel under the desk and be serviced. Her licking technique combines sensuality and elegance, keeping it engaging even over long periods.

The plot follows a married beautiful secretary devotedly serving her boss, with a calm pace that evokes a realistic sense of infidelity, making one think such a lifestyle could be plausible. The boss role, played by Jitta, is known for his coercive image but here he's rarely seduced by a genuinely infatuated secretary, adding a fresh twist. However, opinions are divided on the male actor casting, with some fans dissatisfied with Pierre's appearance. Viewers hoping for more varied erotic scenes might find it lacking.

Overall, the work includes intense elements like raw insertion and internal ejaculation, highlighting Natsume Saeharu's unwavering dedication to her boss. Those who prefer simple痴女 (slut) subjective perspectives might find the frequent appearance of male actors immersion-breaking, but others can enjoy it fully. The pricing feels a bit high, but for Natsume Saeharu fans, it's a must-watch piece.
