This release features a specially curated collection of training videos selected by the editorial team of an SM magazine from numerous submissions. The subjects of the training are two women: Yayoi, a slender and youthful-looking college student, and Maso woman Kako, who has undergone long-term conditioning. Yayoi has been interested in SM since childhood, entered into a slave contract with a man before college, and has since been trained by other men, living as an anal rental beast. Kako, over more than a decade since her college days, has been raised by men to become a livestock-like being specialized in having her body used to extract semen. This video documents various training acts including forced lesbian sex, creampie, semen cleanup, forced cunnilingus, double-headed dildo coupling, anal orgasm, abandonment punishment, double semen drinking, repeated bondage with anal hooks, semen-sharing kiss, orgiastic foursome, anal sex, tight bondage, whipping, long anal dildo insertion, and sexual slave sex training. Captured as a rare record, it shows Yayoi blossoming with delicate masochism amid pain and humiliation, while Kako exists solely to fulfill male desire by producing semen. Filmed by amateur SM enthusiasts, this is a raw and intensely lewd video without any AV-style acting, staging, or narrative. Be sure to watch.
