What is KissXSis about?

The story begins with Keita Suminoe, a male third-year junior-high school student studying for his high school entrance exams. He is living in a home with his older twin stepsisters, Ako and Riko, who share no blood relation to him, and they help him prepare for his exams. Even though he initially dislikes himself for it, he begins to become attracted to his two step-sisters, and his two parents encourage him to eventually get married to one of them.

After Keita's graduation, Ako and Riko arrive to find they were too late to get the second, or any button, off of Keita's blazer. They decide to, against Keita's will, hold a draw for consolation prizes from Keita, with them, Mikazuki and Miharu as participants. Ako's hope backfires and ends up getting Keita's shirt collar, Mikazuki wins the opportunity for Keita to flip her skirt, though he is unaware she wasn't wearing any underwear. Riko wins a chance to kiss Keita in front of everyone, but is too embarrassed to do it. Miharu gets the remaining prize, to spend ten minutes in the equipment room alone with Keita to do anything. Keita simply uses the time to thank Miharu, but after a slip up, they end up in a compromising position, leading Ako and Riko to assume the worst. Later that night whilst Keita goes to sleep, Ako and Riko make a move on him, though this just gives Keita weird dreams.
