Kiss x Sis

Synopsis

Keita Suminoe is a middle school student who is preparing for his high school entrance exams. However, his life is constantly disrupted by his two older twin step-sisters, Ako and Riko. While not blood-related, their aggressive romantic advances toward him create a "taboo" love triangle. As Keita tries to focus on his studies and get into the same high school as his sisters, he finds himself increasingly caught up in their bold (and often highly suggestive) antics.
