Haruka Araki, 30, is a full-time housewife with a well-toned athletic body who devoted herself to kendo in her student days. She has a family of three, including her husband, an office worker, whom she has been dating since her university days, and their daughter. "I can't help it if we have sex less after I got pregnant, but that didn't change even after I gave birth...but my libido has actually increased (laughs),"Haruka says shyly. "When I can't hold it in, I use my fingers or a vibrator..." She has been making up for the lack of sex, which occurs about once a month, by masturbating. "Actually, it was both my husband's and my first time, so I wondered if sex would actually feel better, and I thought I'd like to have a skilled professional actor take the lead, so I applied." We will do our best to meet the expectations of this wife who chose to film an adult video for her first infidelity, and she will experience the stimulation and pleasure of another man's penis to the fullest.
