Demon Father

Synopsis

Following Marina's mother marrying the much younger Kouzou Akizuki after leaving her father, Marina puts up with the situation, but her sister Airi holds a grudge against him for upsetting their family. Airi soon uncovers that Kouzou has a sinister side, engaging in improper acts like smelling the underwear of his underage stepdaughters and craving their innocence. With their mother frequently absent, Kouzou exploits the circumstances to pursue his desires. Unable to resist the allure of youthful bodies, Kouzou gives Airi a potent aphrodisiac that removes her restraints, causing her to give in to his twisted demands. Over time, Airi starts to find pleasure in this depraved arrangement, descending further into a cycle of sexual corruption. Seeing the drug's effectiveness, Kouzou continues using it on other girls, forcing them to fulfill his perverse wishes in degrading ways.
