The series 'Haji+ Shinchishin' follows the escalating sexual debauchery of a once-innocent student council. It begins with the seemingly pure student council president, whose shame and curiosity are brutally exploited. She is systematically broken down through a series of increasingly hardcore BDSM encounters, including public humiliation, gangbangs, and intense bondage sessions. Her supposed friends and fellow council members are revealed to be depraved nymphomaniacs who orchestrate her downfall for their own twisted pleasure. Each episode dives deeper into depravity, showcasing her transformation from a shy girl into a broken, cum-addicted pleasure slave. The arc climaxes with her complete and total submission, eagerly participating in the most extreme orgies and accepting her new role as a public-use cocksleeve for the entire school, her mind shattered and her body forever craving the brutal fucking that defines her existence.
