Introducing a new project: "Chastity Belt Dial Lock Unlock Challenge." In this unique challenge, women must endure the urge to urinate while attempting to guess the correct three-digit combination to unlock their chastity belt dial lock. If they solve it within the time limit, they're told the correct number—but hints are intentionally insufficient, and wrong guesses are frequent. The women repeatedly cry "It won't open, it won't open!" as they make mistake after mistake. This project captures the intense struggle of holding it in and the inevitable, realistic moments of leakage. In this release, four women take on the challenge in different ways. [Haru], an office lady, withstands mounting urinary pressure but fails to find the correct code, covering her face and whispering, "I'm so embarrassed." [Miho], an apparel store worker, crosses her legs tightly and struggles desperately, leaking before any hint arrives, soaking her denim, yet smiling and saying, "I feel so relieved." [Yuri], a company employee, has her genital area restricted by the device, making it nearly impossible to hold it in. Flustered and panicked, she strikes odd poses one after another, eventually overwhelmed by despair and unable to resist, she lets go. [Arisa], a nursery school teacher, doesn't need to hold it at all, yet her authentic breathing and reactions during the act are captivating. She's unlocked while being watched by a crew member, blushing deeply in humiliation. [Ako], an operator, doesn't open it the proper way—instead, she forcibly breaks and pries open the lock. Her clumsy nature shines through as she drops the device and starts urinating, delivering a natural, generous flow that's highly satisfying to watch. This work highlights the realism of endurance, shame, and accidents, making it a standout new series for fans of intense, authentic pissing content. *Facial exposure in main feature.
