Married for four years, Reiko Kobayakawa is a neglected wife with unfulfilled desires and a monstrous libido. When her work-obsessed husband goes on a business trip, her sexual urges go wild. She satisfies her cravings by sucking the key man's dick, having sex with a sexy lingerie salesman, and extracting semen from a delivery man with face riding, tit fucking, and blowjobs. The masochistic wife is then tied up, gagged, and pleasured by two delivery men in an oil-drenched 3P sex session, shaking her huge tits and ass as she orgasms repeatedly!
