Dearest Blue - Episode 1

In a game called "The Sacrifice," rich people compete to strip participants of their virginity, including the student council president Ootori Rio. The vice president Kouzuka Mamoru, who secretly loves Rio, agrees to enter to protect her. He first encounters Rio's talent agency president Akitsugawa Jinsaku and his daughter, idol Yoshikawa Noa. Mamoru begins by sexually manipulating Noa under the guise of her job, and eventually they engage in coitus. After discussing Rio's father's crimes, Mamoru forcibly attacks and rapes Rio against her will, penetrating her forcefully and cumming inside her. Rio suffers physical and sexual changes and is then subjected to training by another participant or player, all under the direction of the game's manipulative organizer.
