The setting this time is the Hakone Onsen hot spring resort! Moreover, the targets are limited to busty female students with E cups or more. To win the prize money, they take on the mission of "licking the water Shizuku off each other's bodies with male customers!". They end up licking the water Shizuku off every part of their bodies, including their armpits, breasts, pubic hair, ass, and vagina! Will they actually get the prize money?
