Yukiko Ishihara works daily as a teacher at a school, but in reality, she has made the solemn decision to live as a sex slave devoted entirely to men. As proof of her submission, she wears a nose ring like livestock, concealing it with a mask while teaching her students. Initially having small nostrils, she has since stretched them to a size capable of hanging a padlock.
Her body modifications extend beyond the nose ring. She undergoes training to stretch her labia by hanging nearly one kilogram of steel sex toys from them, while her nipples have been enlarged and elongated—now grown as large as a baby's penis.
Her anal training continues to progress, with anal penetration already possible, and she is set to undergo further stretching with even thicker objects. Additionally, padlocks serving as chastity devices are attached to her labia piercings, with the keys kept solely by her master.
This video documents her regular training sessions and includes a slideshow of photos sent as special bonus material. This work consists of submitted footage filmed by an amateur BDSM enthusiast, containing no scripted performances, artificial production, or narrative elements typical of commercial adult videos. Instead, it presents a raw, explicit, and authentic visual record, capturing her true reality as a sex slave.
