Keiko-san (25), a piano teacher from Shimoshima, is a straightforward and gentle girl who enjoys watching anime and sleeping (laughs). Despite her innocent demeanor, she has a surprisingly erotic body when she's undressed, shocking everyone! She boasts a magnificent H-cup voluptuous bosom and a luscious figure, and she's also a virgin! When caressed, she reacts extremely sensitively, and her private parts become soaked; in fact, she's very erotic and easy to arouse.
