SOD's popular series 'Sex Clinic' reaches its 20th installment, celebrating with a request campaign featuring 7 special scenarios from about 120 user suggestions, all newly filmed in a 240-minute production! However, upon watching it, I feel the series' essence is lost. First off, the inclusion of a blonde gal raises questions; fans of this series seek 'business-like eros,' 'serving spirit eros,' and the unique worldview like full-body erogenous zones that defined it. Recalling past masterpieces like Aoshi's starring role, the gap is clear, with key elements missing here. Ayame Tsuzaki's approximately 30-minute appearance is indeed outstanding, showcasing her beauty and acting skills with high satisfaction, but other parts fall short. It's disappointing that scenes from the package and sample images aren't in the main content, and the overall feel lacks the series' signature touch. Hibiki Otsuki's role is unclear, and despite being a request-based project, it seems directionless. Overall, this doesn't feel like Sex Clinic; it's more like a haphazard hospital-themed shoot, missing the core element of married nurse struggling with sex at work that drew fans in. Oto Arisu might be the main focus, but the blonde nurse combo feels off, and preferences vary. For the next installment, I hope to see a revival with stronger netorare elements and medical tool-related dialogue, returning to the series roots. As a milestone 20th work, it's hard to call it fitting, leaving fans with mixed feelings.
