The latest installment in the Excretion Experiment Observation Series returns after a long absence as the sixth entry in the "Stopping Midway" series, exploring whether girls can control their urination after holding it to the limit. This time, the girls are given a small cup rigged to look like a toilet, equipped with an action camera. They are allowed to release only as much urine as the cup can hold without overflowing—meaning they can only let out small amounts at a time. As a result, they should feel unsatisfied and anxious, fidgeting throughout the experiment. However, this round gathered girls with weak control, causing every experiment to end in failure. Some soaked their feet completely, while others failed to stop the flow, emptying their bladders in two or three spurts. Naturally, the failed participants faced extremely embarrassing punishment games. This time, the equipment has been upgraded with improved design and super slow-motion filming, made lighter and more affordable to appeal to a wider audience. Four girls take part in the experiment. Initially, they manage to hold back relatively well, but their control quickly becomes disastrous. The urine they release veers sharply to the left of the cup, mercilessly streaming down their thighs and onto the floor. They endure their humiliating punishment games standing in the puddles they created. Next is a girl with extremely weak stopping ability—reaching her limit, she empties her bladder completely in just two urinations, drenching her legs and the floor, with no chance of capturing the flow in the cup. Punishment is inevitable. Another girl adopts a unique endurance style: gripping her panties and taking tiny, nervous steps. One participant ignores instructions entirely, urinating freely and uncontrollably, soaking the floor. Her poor control is so severe that she even leaks during the interview. The tanned, sexy gyaru girls initially stop successfully, but gradually lose control, exceeding capacity by the fourth attempt. In the end, unable to manage their bladders, they leave behind sizable pools at their feet. Once again, punishment follows. Produced by Haisetsuya. Full facial exposure in main feature.
