The series 'Eisai Kyoiku' follows the brutal sexual 're-education' of Kaori Aso, a seemingly untouchable and pristine student council president. Her life is systematically destroyed by her conniving stepfather, who blackmails her with a secretly recorded video. He forces her into a depraved curriculum designed to break her spirit and remold her into a mindless sex toy. The 'lessons' begin with him and escalate to involve his degenerate colleagues, subjecting Kaori to relentless gangbangs, bukkake sessions, and public humiliation. Each episode details her psychological and physical degradation as she's passed around, her orifices used and abused until her defiant will shatters completely. She ultimately succumbs to the brainwashing, her mind broken, transforming from a proud idol into a debauched, cum-craving slut who eagerly accepts her new role as a public-use toilet for any man's pleasure.
