M female housewife, Fujimori Rieko, 31 years old. Unable to find pleasure in sex with her husband, she seeks it from a sadistic lover, becoming aroused by public, taboo M play during the day. Aroused by humiliation play, reaching orgasm through forced masturbation, eagerly taking a large penis deep into her throat, restrained in an 'M' shape and brought to orgasm repeatedly with a vibrator and dildo. Made to wear a collar and walk on all fours for double penetration, becoming even more aroused as an erect large penis is screwed into her womb for a threesome, standing sex, inverted sex, continuous rapid piston thrusts resulting in internal ejaculation, driven to a frenzied orgasm.
