Elegant and refined housewife Ryo Hitomi, age 45. She harbors a secret side—her body instantly reacts just from being watched. Weak against humiliation play, shame masturbation, and deep-throat semen swallowing, her desire quickly spirals out of control. Bound tightly with X-shaped restraints, she's brought to climax after climax through relentless torment by electric massagers and vibrators. In a blindfolded threesome with two men, erotic fluids gush from her crotch as her moans grow endless. Stimulated by these abnormal acts, Ryo becomes aroused beyond reason, climaxing uncontrollably again and again.
