Amateur girls were asked to give a reward if they washed the bodies of male customers in a mixed-gender open-air bath. It's OK to cover yourself with a towel if you think it's embarrassing. There are a lot of male customers at the hot spring. It's embarrassing to even ask, "Can I wash your body?" The girls panic! They even take a commemorative photo with their ahegao faces? A soapland experience where they are fucked by bad men.
