Futabu!! 第1話

The members of the Futabu, also known as the Futanari Club, are in for a treat as they head to the Manra Valley onsen for a much-needed relaxing vacation. While their official reason for the trip is to research the local harvest festival for a high school project, their real motive is to let loose and have some fun. The springs at the onsen have a special allure—they're an aphrodisiac, promising an unforgettable experience for the club members.
