ACZD-137 The Diary of Keiko, the Pet Girl

This video is a compilation of footage submitted to the SM magazine 'Maniac Club.'
Keiko (alias), a human livestock, has vowed to spend the rest of her life serving sexually as a masochistic livestock under her master, Mr. Tsukushi Yomichi (alias).
Keiko, who had been practicing self-bondage and masturbation since childhood, was raised and trained by Mr. Tsukushi during her university years. Even after graduating, while working full-time in caregiving, she spends almost all of her remaining time in the livestock shed provided to her, training 24/7, 365 days a year to become an exemplary sex-slave masochist.
On days when her master does not visit, she completes the assigned female livestock programming, practices vaginal muscle exercises and oral techniques for sexual servitude, records self-inflicted masturbation videos as requested, creates perverted homemade outfits, writes erotic fiction, and draws illustrations as part of her daily routine.
This work is a documentary video of an actual masochistic couple who submitted their self-recorded SM play footage. It lacks the acting, production, or storyline typical of AVs. Please be aware that this is a documentary of a real masochistic couple before purchasing.
