Ryo Hitomi is a refined housewife, 45 years old. This beautiful wife has a masochistic tendency. She gets wet just by being watched, gets aroused by humiliating play, masturbates in shame, and has semen splashed on her after deep throating. She is stuck to an X-rated restraint device, made to cum over and over again by being toyed with an electric massager and a vibrator, and moans as she squirts erotically from between her legs during a blindfolded threesome with two men. Ryo gets turned on by such abnormal play and goes crazy with pleasure.
