HUNTC-552 A flat-chested girl challenges herself to enter the men's bath wearing only a towel wrapped around her waist! If she's found out, she's out!? A test of courage at a hot spring inn! The girls enjoy the thrill... What will happen if they're found out!?

These flat-chested girls aren't taking on the men's swimsuit challenge... they're taking on the challenge with just a towel wrapped around their waists! A challenge in the men's bath! A challenge far more difficult than the men's swimsuit challenge! Three naive girls who no longer find normal sex exciting come up with a crazy challenge. One day, while on vacation, they decide it would be fun to dress up as men and go to the men's bath, so they come up with the idea for the "Men's Bath with Just a Towel Wrapped Around Their Waist Challenge!" They don short wigs and men's trunks and head into the bath! Luckily, all three of them are flat-chested and small-breasted, so they can somehow hide their upper bodies. However, their lower bodies are obvious, so they only have to wrap themselves in a towel wrapped around their waists! They head to the bathhouse nervously... and find themselves surrounded by men completely naked! Some of the men are suspicious at first, but they're relieved that they don't seem to notice. Seeking further excitement, the three increase the difficulty of the challenge by approaching other male customers and soaking in the bath with them, and the thrill is intoxicating. The excitement was at its peak, and they were excited to go to an open-air bath next, but when the two girls went to the toilet, they left. So they were left alone to bathe in an open-air bath with male customers. Oh no! They've been found out! Rough men started to swarm them. They started groping their bodies and even had sex with them... And when they went to the toilet, they were found out and became the men's prey! The price of this ultimate thrill was sex with a strange older man.
