Ueno Aiko(上野愛子)

Aiko Ueno is a Japanese Adult Video (JAV) actress who debuted around 2004. Her career appears to have spanned at least a couple of years based on available information. Analyzing her work titles and genre tags, Ueno primarily starred in JAVs featuring mature women ("人妻" meaning married woman/housewife), often incorporating elements of forbidden romance and taboo themes. A recurring characteristic appears to be her involvement in productions highlighting large breasts (巨乳). Common elements in her works include masturbation (オナニー), vibrators (バイブ), and scenarios involving older sisters ("お姉さん") or sisters-in-law. Based on the limited information, there doesn't appear to be a significant evolution in her genre preferences over her career. She seems to have consistently worked within the niche of mature women-themed JAVs with a focus on busty performers. Ueno worked primarily with KT Factory, appearing in individual titles and at least one series, "Mou Gaman Dekinai." Her style seems to center around playing the role of a sensual and desirable older woman, often placed in suggestive or illicit scenarios.
