This video is a compilation of videos posted to the SM magazine "Mania Club". Keiko is a masochistic woman who has vowed to live the rest of her life as a masochistic livestock providing sexual service to her master, Hiromichi Chikushi (pseudonym). Keiko, who has repeatedly engaged in self-bondage masturbation since she was a child, was trained and kept by Mr. Chikushi, whom she met by chance during her university days. Even now that she has graduated from university, she works full-time as a caregiver, but spends most of her time training to become a masochistic livestock dedicated to sex 24 hours a day, 365 days a year in the livestock shed she has been given. On days when her master does not visit her at her livestock shed, she completes the female livestock program she is ordered to do, and also trains her genital contraction and lips for fellatio service, and shoots a self-deprecating masturbation video as requested. She makes perverted handmade costumes, and spends her days writing fantasy novels and illustrations. The video was filmed by Keiko's owner, Hiromichi Chikushi, at the request of the editorial department, and includes footage of the livestock Keiko being sexually processed in the livestock shed where she lives, as well as forced lesbian sex with Chika, a slave woman also owned by Chikushi. The main content is: being tormented in a BD costume; being hit with slippers while having sex with a sex toy; making Chika have an orgasm with a five-finger penis glove; caressing the clitoris, vagina, and anus with a three-pronged sex toy and beating with a leather paddle; making Keiko masturbate before rental training to make her horny; and managing her breathing with a paper diaper soaked in urine. Note: Unlike Chika, who serves the same master, Keiko's delicate and small body has not been modified, and she has been trained as a livestock woman dedicated to sex service, to make men horny and use her sexual techniques to milk their semen. In the early stages of her training, she was trained to serve the penis with all three holes, her mouth, vagina, and anus, but to differentiate herself from Chika, she has been banned from anal sex. Currently, she gives pleasure to her sensitive anus with toys the size of a finger or a vibrator, but does not use thicker toys. According to Chikushi, she will give him her second anal virginity on his 40th birthday.
