HSODA-122 | I found a flat-chested girl at a hot spring inn! How about trying a flat-chested challenge by entering the men's bath with just a towel on?

A flat-chested girl found at a hot spring inn takes on a flat-chested challenge, entering the men's bath with only a towel on, aiming for a large cash prize! She boldly pretends to be a man and doesn't hide her chest! She charges into the men's bath with her flat chest completely exposed! If she completes various missions without being discovered, she wins the prize money! Naturally, the more difficult and erotic the mission, the higher the prize money! Will she be able to talk to the male guests without being discovered? She secretly gives a handjob without being noticed by the other male guests! She secretly gives a blowjob? She tries the most difficult flat-chested sex challenge, but... she gets discovered? The flat-chested girl gets very excited by the excited male guests! Will she be able to win the large cash prize by putting her body on the line and having a friendly erotic orgy with everyone, successfully collecting a large amount of sperm?
