Andrea Obermeier, professionally known as Kerstin, is a retired German adult film actress who gained attention in the late 1990s as one of Germany's emerging talents in the pornography industry. Active primarily between 1997 and the early 2000s, she appeared in several European adult productions, including the 1997 title "Geiles Interview Video" and scenes in series like "Nachtschwester Stafanie." Her performances often featured in hardcore and amateur-style content popular at the time. Obermeier retired shortly after her initial success, leaving behind a modest but dedicated fanbase.
Little public information exists about her personal life or post-career activities, as she maintained privacy. Today, her vintage videos remain accessible on adult platforms, appreciated by enthusiasts of retro German pornography. As a representative of the era's domestic talent, she contributed to the expansion of the local adult entertainment scene before stepping away from the spotlight.
