Three years have passed since "The Noble Daughter's Humiliation: Days of Dual-Penetration." Following her initiation into anal and vaginal training in the previous installment, the true masochist Kazumi's degradation has continued unabated. Her life as a sexual servant, stripped of all dignity, embracing complete submission to her master, is fully exposed—years filled with constant conditioning and abuse. This period included outdoor toilet training, lesbian BDSM sessions, prolonged naked confinement, and permanent anal stretching. Part 1 features episodes such as "Outdoor Dog Play" and "Lesbian Play 1," heralding new developments in her ongoing downfall.
