Sansha Mendan: Rensa Suru Chijoku Choukyou no Gakuen / School of Obedience

The main character of the hentai, Ryo Kawabata, simply loves to watch women grovel before him, who are forced to obey him. Since he is a student, all his victims are somehow connected to the educational institution - female students and teachers. Almost all the teachers gave in to his will and influence and stopped resisting, carrying out any of his most lustful orders. However, among them there was one who was able to stand up for herself and not give in to Ryo-kun's provocations. She turned out to be a young transferred teacher, Yuna Hajura. She informed the academy administration of her student's misdeeds, but there was no reaction due to the risk of damaging the institution's reputation. Instead, Ryo was simply expelled and his crimes went unpunished. Without wasting time, our hero enrolls in another academy, where he soon meets Aina Hagiura - Yuna's younger twin sister. Thanking the devil for incredible luck, he decides to take revenge on his offender through Aina and goes on a hunt...
