Eiken

When Mifune fell hands first into Chiharu's bulbous, bulging bosoms one day, he had no idea his life would change forever. For the girl is a member of Eiken, a school club filled with busty beauties such as banana-loving Kirika and the exceptionally top-heavy child Komoe, and they've decided to recruit the boy as one of their own! With perverted situations at every turn, Mifune finds himself in frequent compromising positions, whether the group is barbequing on vacation, participating in a school 'endurance challenge' or fending off sexual advances from friends and family.
