Teacher "Shiokawa" becomes deeply involved with her student "Yugo," leading to a forbidden romance. However, "Yugo's" girlfriend "Ai" grows jealous of their relationship and gradually begins taking steps to dominate "Shiokawa." She starts by gathering her brother and friends to kidnap "Shiokawa" and carry out a brutal rape. During the assault, "Ai" films "Shiokawa's" violated state and uses the footage as leverage to completely subjugate her. Gradually, "Shiokawa" is subjected to various forms of BDSM training, including tight bondage, outdoor exposure, repeated female ejaculation, nipple play, whipping, female dog training, forced masturbation, and more—transforming her into an extreme female masochist. Through this process, she embraces her own desires and evolves into a new being. #EiP
