Rio is a curvy, big-breasted housewife who married a younger man she met at a matchmaking party. Her husband does not know that she once worked as a dominatrix at an SM bar—or that she still satisfies her intense desires with a longtime submissive sexual partner because she cannot show her true dominant side at home. Three months into marriage, she enters porn without telling him. She begins by licking a submissive man's nipples, tormenting his feet, and making him perform urine-soaked cunnilingus; then uses insertable objects for anal play and gives her partner a teasing handjob; finally, she tries her first threesome with two submissive men and punishes them with a strap-on.
