Miya is the older stepsister of Ruuya. The dude lives an average life and most of the time he is with his friend. His life changes when he randomly chugs a drink which arouses his sexuality! So, now he is insatiable and has lots of nympho fun until he ends up finding the vaccine for the drink. Amazing hentai!
