A group of women locked in chastity belts must endure intense urges while attempting to unlock them in this challenge. The lock uses a three-digit combination, turning it into a puzzle-like guessing game. The rule is simple: if they guess the correct code within the time limit, they'll be told the right numbers—but it's actually a trick set up by the Female Excretion Sect. False combinations are repeatedly presented, ensuring no one escapes easily. The real goal? To make them piss themselves before they can escape. Women desperately keep entering numbers as their bladders reach the breaking point, their anguish and panic clearly visible. The methodical, busty girl carefully inputs numbers but is misled by fake hints, forcing her into repeated attempts. The big-titted innocent girl starts near her limit and randomly guesses digits, ultimately failing to hold it in. The husky-voiced older sister systematically tries combinations, yet repeats numbers due to stress, and just before receiving the final hint, she clutches her head screaming, "I can't take it anymore," retiring in defeat. The prim-looking girl, completely drained, refuses to give up and engages in a brutal struggle, but eventually wets herself on all fours. The cute, child-faced beauty fidgets nervously during her attempt and quickly ends up peeing herself. Their intense, humiliating performances make this a must-watch for fans of the Female Excretion Society’s full-face release series.
