Based on the erotic game by Appetite.

Ryou, a teacher, had a big problem that he could not discuss with anyone. It is the personality of his younger sister, Saori, who has excellent grades and good looks. In front of others, Saori puts on a cat's face and acts like a good girl, but in front of Ryou, she becomes selfish and plays sexual tricks on him as an outlet for her stress. Ryou wants to break free from this dangerous relationship, and is elated when a female teacher confesses her feelings for him, but Saori catches him in the act...
