Keiko, a masochist, vows absolute submission to a perverted sadist and deeply indulges in real and intense humiliation training. With her surroundings shut out by a vibrator and her hearing blocked by headphones, she experiences continuous orgasms. Her lewd masturbation is accompanied by another female slave performing intense cunnilingus on her shaved genitals, leaving her writhing in pleasure with her body filled with white discharge and love juice. She raises a voice of delight as she performs toe service with an anal vibrator still inside her. Additionally, she is tied up with her legs spread wide, her handmade slave panties exposing her private parts, and she endures intense torture with sex toys. The beating on her buttocks is converted into pleasure in her brain, causing her to convulse with a dirty, animal-like pleasure. In a livestock pen, she engages in oral training, desperately performing blowjobs with clumsy tongue techniques. Along with another female slave, she simultaneously takes care of a sadist's anus and penis, and is soon thrown into chaos by the pleasure of being used in both holes. With a vibrator applied to her vagina and tied to a pole outdoors, while another female slave becomes a receptacle for a sadist's semen, a jealousy-fueled masochistic orgasm is born. Unable to bear the pain of not being allowed to use her own holes, she begs for a penis with fervent blowjobs, but is eventually broken by a humiliating infantilization diaper play. The amateur masochist Keiko, whose body and mind are under the control of pleasure, is depicted in an Abnormal SM training video.
