This work compiles footage featured in the SM magazine "Mania Club," depicting Keiko, a genuine female masochist, fulfilling her vow to live as a sex slave under her master, Yodo Tsukushi. Having engaged in self-bondage and masturbation since childhood, she was discovered and systematically trained by Tsukushi during her university years. After graduation, while working in elder care, she continues her life as a full-time, 24/7 sexual livestock in a dedicated animal pen. On days when her master does not visit, she follows strict routines: vaginal contraction exercises, oral servicing lip training, filming self-abusive masturbation sessions, crafting perverted handmade outfits, and writing fantasy novels and illustrations. This video was shot by owner Yodo Tsukushi at the request of the editorial department. It includes highly erotic and shocking content such as sexual maintenance sessions in the livestock pen and forced lesbian scenes with Chika. The footage features diverse BDSM acts, including triple stimulation with nipple vibrators, anal hooks, and vaginal vibrators, flogging with rose whips, blowjob servicing and intercourse inside the pen, enforced electro-stimulation torture, clitoral teasing with clips, bondage domination with whipping, full exposure of genital and anal areas, and gangbang-style mental orgasms. Content may vary depending on distribution platform.
