Veteran actress Natsuko Kayama, who has showcased masturbation in numerous works multiple times, has become a staple in AV with her masturbation scenes...but we had yet to see her serious self-pleasure! Her provocative masturbation with lewd language directed at the camera, the real-life masturbation of a dissatisfied housewife, and her triple dildo masturbation solely for her own pleasure, etc., Natsuko Kayama's serious self-pleasure is more lewd and obscene than sex! Even a veteran actress called a legend sheds one layer and reveals herself to be a vixen!
