The joys of summer break; warm weather, sun soaked beaches, time off from school, and in the case of Yuuta Yamauchi, a torrid love affair with your cousin. Summer Sis details the sexual relationship between Yuuta and his cousin, Kei Higashide, who offered to help him study for his college entrance exam.
