Reiko Shimura is a 38-year-old woman exuding mature charm, with a figure measuring 162cm tall, 86cm (E-cup) bust, 63cm waist, and 90cm hips. Before marriage, she worked as a receptionist, and she often hears comments about her large, rounded buttocks stimulating her groin. Her relationship with her husband involves sex only about once a month, so she frequently enjoys masturbation. One of her favorite foods is cucumber, whose unique texture she finds perfectly suited to her.
