On a city street, we approached a cute amateur girl and invited her to participate in a challenge: wear a swimsuit into the men's bathhouse, wash her body, soak in the tub for 10 minutes, and win a cash prize. However, the swimsuit was rigged to dissolve in water—a shocking prank! As a result, she ended up completely naked in front of the men present at the bathhouse. Flustered and overwhelmed, the amateur girl was then pushed into even more humiliating games. The atmosphere of the moment and her genuine reactions are the highlights.
