Hayashibara Eiko (Kikuchi Sayaka)(林原栄子（菊地沙也加）)

Hayashibara Eiko, also known as Kikuchi Sayaka, is a Japanese Adult Video (JAV) actress with measurements B87 W60 H89. While the exact details of her debut are unclear, her filmography suggests a career spanning from the early 2000s to the early 2010s, with a potential return in 2017. Her work primarily focuses on the mature woman ("熟女" or "jukujo") genre, often portraying married women ("人妻" or "hitodzuma") and MILF ("義母" or "hahaoya") themes. A strong emphasis is placed on onanism ("オナニー"), with frequent appearances of vibrators ("バイブ"). Other recurring themes include infidelity ("不倫"), incest ("近親相姦"), and group scenes ("3P・4P"). Analyzing her filmography, a slight shift in focus can be observed. While the "jukujo" and "hitodzuma" themes remain consistent throughout her career, some of her earlier work also features "chijo" (slut/bitch) elements. Towards the later part of her career, there is a noticeable increase in titles and series focusing on incestuous relationships, particularly those involving stepmothers and mothers.
