Maki Taniguchi, 53 years old. Her late husband, who once ran a real estate company, passed away five years ago at the age of 73. Due to his age, he had not been sexually active for years, though Maki was always sexually driven and desired fulfillment. After his death, she fell into a sexless life once again. Two years ago, she began a relationship with a bank branch manager from a business connection, enjoying a satisfying sex life—until a year ago, when he was transferred, leaving her sexless once more. During this time, she discovered RUBY's online casting call for mature women. Having long been interested in adult videos, Maki decided to make her debut.
