Marina Eto, 30, runs a beauty salon. A sparkling ring adorns her left hand... Her husband is the president of a real estate company, making her a true elite and celebrity. Marina, meanwhile, not only enjoys financial resources but also a high sex drive. Her age and work fatigue make her hard to please. Furthermore, because they're both masochists, she's not satisfied with sex with her husband, who doesn't dominate her even though she wants to be dominated. She's secretly found a partner to flirt with. Her sex friend recommended her for this AV appearance. Taking the suggestion seriously and appearing in the film suggests her sexual appetite and curiosity know no bounds. It seems she truly calls herself a masochist, and a real masochist. When the male actor observes her masturbating with her legs spread wide, she fidgets and squirms with embarrassment, but she also seems excited and doesn't try to stop. After that, she is teased with a vibrator, her armpits are sniffed and licked, and each time, her excitement seems to increase. If things continue like this, it will become even more erotic as they lead to sex, so please see for yourself.
