The Taste of My Sister ~Brother Captured by His Sister's Vagina~ SDMU-638

SOD's first anime submitted by amateurs. The 実家's brother is a stubborn and seductive "sister" who is a girl's school student. An incestuous relationship between mother and friend Nao. The brother is abnormal and the sister is dependent on the sister, so the brother is the "adult's behavior" and the request is made. The sense of guilt, the sense of inadequacy, the sense of guilt, the sense of inadequacy, the sense of guilt, the sense of inadequacy, the sense of guilt... There is a relationship between the families of the students.
